ABSTRACT OBJECTIVE This study aims to investigate handgrip strength and dynapenia prevalence among older adults stratified by Brazilian macroregions. Additionally, we aim to evaluate the overlap between dynapenia and Instrumental Activities of Daily Living (IADL) disability, depression, and executive dysfunction on a national basis and by each Brazilian macroregion. METHODS This cross-sectional analysis was based on data from the Brazilian Longitudinal Study of Aging (ELSI-Brazil). A multistage cluster sample design was used, with a representative population-based study of non-institutionalized community-dwelling Brazilians aged ≥ 50 years from 70 municipalities across all five macroregions of the country. The outcome variable was dynapenia. Covariables were IADL disability, depression, and executive dysfunction. The Brazilian macroregions were used for stratification. In addition, the following additional variables were included: age group, gender, education level, macroregions (North, Northeast, Southeast, South, and Midwest), self-reported health, multimorbidity, and falls. RESULTS A total of 8,849 (94%) of the sample provided complete information for the handgrip strength assessment and were included in this analysis. Dynapenia prevalence was higher in North and Northeast regions (28.5% and 35.1%, respectively). We identified statistically significant differences between different macroregions for dynapenia, IADL disability, and verbal fluency, with worse values in the North and Northeast regions. In the North and Northeast macroregions, nearly half of the subjects that presented executive dysfunction and IADL disability also had dynapenia. There was a more significant overlap in the prevalence of all four conditions in the North and Northeast regions (4.8% and 5.5%, respectively), whereas the overlap was smaller in the South (2.3%). There was also a smaller overlap in the prevalence of dynapenia and depression in the South (5.8%) compared with other macroregions. CONCLUSIONS Macroregions in Brazil exhibit marked differences in the prevalence of dynapenia and in its overlap with IADL disability, depression, and executive dysfunction.

Objective: To translate, establish the diagnostic accuracy, and standardize the Brazilian Portuguese version of the European Cross-Cultural Neuropsychological Test Battery (CNTB) considering schooling level. Methods: We first completed an English-Brazilian Portuguese translation and back-translation of the CNTB. A total of 135 subjects aged over 60 years – 65 cognitively healthy (mean 72.83, SD = 7.71; mean education 9.42, SD = 7.69; illiterate = 25.8%) and 70 with Alzheimer’s disease (AD) (mean 78.87, SD = 7.09; mean education 7.62, SD = 5.13; illiterate = 10%) – completed an interview and were screened for depression. The receiver operating characteristic (ROC) analysis was used to verify the accuracy of each CNTB test to separate AD from healthy controls in participants with low levels of education (≤ 4 years of schooling) and high levels of education (≥ 8 years of schooling). The optimal cutoff score was determined for each test. Results: The Recall of Pictures Test (RPT)-delayed recall and the Enhanced Cued Recall (ECR) had the highest power to separate AD from controls. The tests with the least impact from schooling were the Rowland Universal Dementia Assessment Scale (RUDAS), supermarket fluency, RPT naming, delayed recall and recognition, and ECR. Conclusions: The Brazilian Portuguese version of the CNTB was well comprehended by the participants. The cognitive tests that best discriminated patients with AD from controls in lower and higher schooling participants were RPT delayed recall and ECR, both of which evaluate memory.

ABSTRACT OBJECTIVE In recent decades there has been an increase in the use of antidepressants (AD) and a decrease in the use of benzodiazepines (BDZ). Prevalence, cumulative incidence, and factors associated with the incidence of AD and BDZ use in a Brazilian population were estimated in this article. METHODS Data were collected with a self-administered questionnaire in a cohort of employees from a university in Rio de Janeiro. The prevalence of the use of AD and BDZ was calculated for 1999 (4,030), 2001 (3,574), 2006-07 (3,058), and 2012 (2,933). The cumulative incidences of the use of AD and BDZ between 1999 and 2007 were estimated by the Poisson models with robust variance estimates. RESULTS In 1999, the prevalence of the use of AD and BDZ were 1.4% (95%CI: 1.1–1.8) and 4.7% (95%CI: 4.1–5.4), respectively; in 2012, they were 5.4% (95%CI: 5.5–6.2) and 6.8% (95%CI: 6.0–7.8). The incidence of use, between 1999 and 2007, was 4.9% (95%CI: 4.2–5.7) for AD and 8.3% (95%CI: 7.3–9.3) for BDZ. The incidences of AD and BDZ use were higher among women and participants with a positive General Health Questionnaire. CONCLUSION In this population, the increase in the use of AD was not accompanied by a decrease in the use of BDZ, showing the prescriptions for psychotropic medication do not follow the currently recommended guidelines for treatment of common mental health disorders.

Resumo Introdução A utilização de indicadores válidos na avaliação do estado nutricional populacional é muito importante. Objetivo Avaliou-se a concordância entre medidas aferidas e autorrelatadas de peso corporal, estatura e IMC, e identificou-se fatores que exercem influência sobre o autorrelato. Método Estudo transversal de base populacional de adultos da Região Metropolitana de SP (N=766). Cálculo dos coeficientes de correlação intraclasse e análises gráficas de Bland & Altman foram conduzidos, avaliando a concordância dessas medidas. Resultados Na amostra total, e para ambos os sexos, foram subestimados o peso corporal autorrelatado e, consequentemente, o IMC, enquanto a estatura autorrelatada foi superestimada. A imprecisão no autorrelato foi influenciada pelo sexo, idade, escolaridade e estado nutricional. A confiabilidade encontrada entre as medidas foi elevada em ambos os sexos e na amostra total (peso corporal CCI 0,951/IC 0,938-0,961; estatura CCI 0,870/IC 0,597-0,939; IMC CCI 0,865/IC 0,677-0,928). A prevalência de excesso de peso pelas medidas autorrelatadas mostrou-se subestimada (13%), quando comparada àquela calculada através das medidas aferidas. Conclusão O autorrelato pode ser influenciado por diversos fatores, produzindo medidas imprecisas. Sua utilização em inquéritos populacionais pode acarretar em uma importante subestimativa do risco de adoecimento e mortalidade prematura por doenças cardiovasculares e metabólicas associados ao excesso de peso.

Abstract Background The use of valid indicators for the evaluation of the nutritional status of the population was very important. Objective The concordance between measured and self-reported data of body weight and height and BMI were evaluated and the factors that exert influence on the self-report. Method This is a cross-sectional population-based study of adults from the Metropolitan Region of SP (N=766). Calculation of the intraclass correlation coefficients and graphical analyzes of Bland & Altman were conducted, evaluating the agreement of these measures. Results In the total sample and for both genders, the self-reported body weight and the BMI were underestimated, while the self-reported height was overestimated. The imprecision in self-report was influenced by gender, age, school level,and nutritional status. The agreement between the measures was high in both genders and in the total sample (weight ICC 0.951/CI 0.938-0.961; height ICC 0.870/CI 0.597-0.939; BMI ICC 0.865/CI 0.677-0.928). The prevalence of overweight by self-reported measures was underestimated (13%) when compared to that calculated by the measured data. Conclusion Self-report can be influenced by several factors, producing imprecise measures. Its use in population surveys may lead to an important underestimation of the risk of illness and premature mortality for cardiovascular and metabolic diseases associated with overweight.

Objectives: To estimate the current prevalence of posttraumatic stress disorder (PTSD) and the diagnosis rate of this disorder ascertained by psychiatrists in training. Methods: We interviewed 200 adults under treatment in a university mental health outpatient clinic. The PTSD diagnoses obtained using the Structured Clinical Interview for DSM-IV (SCID-IV) were compared with the patients’ medical records. Results: Forty-one patients (20.5%) were diagnosed with current PTSD, but only one of them (2.4%) had previously received this diagnosis. This study confirms that although PTSD is highly prevalent among mental health outpatients, it is remarkably underdiagnosed in teaching hospitals. Conclusions: These findings suggest that psychiatrists in training may be failing to investigate traumatic events and their consequences and strongly indicate that trauma-related issues should be given more prominence in psychiatry curricula and psychiatrist training.

Resumo: O objetivo foi analisar a agregação do consumo de álcool, tabaco, excesso de peso e sono curto em adolescentes brasileiros. Trata-se de estudo transversal, multicêntrico realizado com base em adolescentes participantes do Estudo de Riscos Cardiovasculares em Adolescentes (ERICA). A amostra foi composta por adolescentes que responderam completamente aos questionários sobre sono, tabaco e uso de bebidas alcoólicas, além de terem realizado antropometria com medidas de peso e estatura aferidas. A agregação foi analisada comparando a prevalência observada com a esperada dos fatores de risco em todas as possibilidades de agrupamento, e seus intervalos de 95% de confiança. As análises foram realizadas no programa estatístico Stata 14, mediante uso do comando svy (survey) para dados de amostra complexa. São 73.624 adolescentes, 25,5% dos estudantes apresentam excesso de peso e 24,2% fazem uso de bebida alcoólica. A agregação dos quatro fatores de risco foi de O/E = 5,6. A prevalência de agregação dos três fatores foi maior naqueles com 15 a 17 anos (P = 4,8). Na análise de ORP (odds ratio de prevalência) da combinação de dois fatores de risco, observou-se que os fumantes têm 11,80 vezes mais chances de também beber quando comparados àqueles que não fumam e vice-versa, nas escolas privadas. Em relação à idade, adolescentes com 12 e 14 anos que fumam têm 15,46 vezes mais chances de também beber e vice-versa. Adolescentes estudados apresentam a presença dos quatro fatores de forma agregada e há relação significativa entre o tabaco e o consumo de álcool.

Abstract: This study aimed to analyze the aggregation of alcohol consumption, smoking, excess weight, and short sleep in Brazilian adolescents. This was a cross-sectional multicenter study conducted with teens participating in the Study of Cardiovascular Risk Factors in Adolescents (ERICA in Portuguese). The sample consisted of adolescents that answered the complete questionnaires on sleep, tobacco, and alcoholic beverages, in addition to having their weight and height measured. Aggregation was analyzed by comparing the observed and expected prevalence of risk factors in all possible groupings, with the respective 95% confidence intervals. Analyses were performed in Stata 14 using the svy (survey) command for complex sample data. The sample included 73,624 adolescents, of whom 25.5% had excess weight and 24.2% consumed alcoholic beverages. Aggregation of the four risk factors was O/E = 5.6. Aggregation of three factors was more prevalent in those 15 to 17 years of age (P = 4.8). In the POR (prevalence odds ratio) analysis of the combination of two risk factors, those that smoked showed 11.80 higher odds of also consuming alcohol, compared to those that did not smoke, and vice versa, in private schools. In relation to age, adolescents 12 to 14 years of age that smoked showed 15.46 times higher odds of also drinking, and vice and versa. Adolescents in the sample presented the aggregate presence of four risk factors, and there was a significant relationship between tobacco and alcohol consumption.

Os objetivos deste artigo são: (i) comparar medidas autorrelatadas de peso e estatura com medidas aferidas; (ii) avaliar o impacto dessas discrepâncias sobre o índice de massa corporal (IMC) e as prevalências de sobrepeso e obesidade; e (iii) aplicar modelos de correção das medidas autorrelatadas e avaliar o grau de melhoria das medidas corrigidas produzidas pelo uso desses modelos. Realizou-se estudo transversal, com avaliação de 4.151 adultos (18 a 60 anos) participantes do Estudo Epidemiológico dos Transtornos Mentais São Paulo Megacity. Foram propostos e testados modelos de regressão linear estratificados por sexo, para a correção das medidas autorrelatadas. Para avaliar a concordância, usou-se o coeficiente de correlação intraclasse para as medidas aferidas, medidas autorrelatadas e medidas corrigidas, bem como o coeficiente kappa para as categorias de classificação do IMC. O peso autorrelatado e o IMC resultantes foram subestimados, ao passo que a estatura foi superestimada, comparados às medidas aferidas. Com todos os modelos de correção, as medidas corrigidas tornaram-se mais próximas às medidas aferidas. As prevalências de excesso de peso, quando calculadas a partir das medidas autorrelatadas, estavam subestimadas em 24% em homens e 28% em mulheres. Com as correções, a subestimativa diminuiu para 8% e 10%, respectivamente. Identificou-se concordância moderada para as medidas autorrelatadas e concordância substancial para as medidas corrigidas, quando comparadas às medidas reais. O uso de equações de correção para dados autorrelatados mostrou-se um método útil para produzir estimativas mais fidedignas da prevalência de excesso de peso e obesidade na população geral, geralmente estimadas a partir de medidas de peso e estatura autorrelatadas nos inquéritos populacionais.

The study’s objectives: compare self-report measures of weight and height with direct measures; assess the impact of these discrepancies on body mass index (BMI) and prevalence of overweight and obesity; and apply correction models to the self-report measures and assess the degree of improvement in the corrected measures produced with the use of these models. A cross-sectional study was performed, assessing 4,151 adults (18 to 60 years) participating in the São Paulo Megacity Epidemiological Study. Linear regression models stratified by sex were proposed for correction of self-reported measures. Agreement was assessed with the intraclass correlation coefficient for the direct measures, self-report measures, and corrected measures, and kappa coefficient for BMI classification categories. Self-reported weight and the resulting BMI were underestimated, while height was overestimated, compared to direct measures. With all the correction models, the corrected measures were closer to the direct measures. Prevalence rates for excess weight, calculated by self-report measures, were underestimated by 24% in men and by 28% in women; with corrections, the underestimation decreased to 8% and 10%, respectively. The results showed moderate agreement for self-report measures and substantial agreement for corrected measures compared to direct measures. The use of correction equations for self-report data proved to be a useful method for producing more trustworthy estimates of prevalence of overweight and obesity in the general population, usually estimated from self-report measures of weight and height in population surveys.

Los objetivos fueron: comparar medidas autoinformadas de peso y estatura con medidas evaluadas; evaluar el impacto de estas discrepancias sobre el índice de masa corporal (IMC) y las prevalencias de sobrepeso y obesidad; y aplicar modelos de corrección de las medidas autoinformadas y evaluar el grado de mejoría de las medidas corregidas, producidas por el uso de esos modelos. Se realizó un estudio transversal evaluando a 4.151 adultos (18 a 60 años), participantes en el Estudio Epidemiológico São Paulo Megacity. Se propusieron y probaron modelos de regresión lineal estratificados por sexo para la corrección de las medidas autoinformadas. Para evaluar la concordancia, se usó el coeficiente de correlación intraclase para las medidas evaluadas, medidas autoinformadas y medidas corregidas, y el coeficiente kappa para las categorías de clasificación del IMC. El peso autoinformado y el IMC resultantes fueron subestimados mientras la estatura fue sobrestimada, comparados con las medidas evaluadas. Con todos los modelos de corrección, las medidas corregidas se convirtieron en más cercanas a las medidas evaluadas. Las prevalencias de exceso de peso, cuando se calculan a partir de las medidas autoinformadas, estaban subestimadas en un 24% en hombres y un 28% en las mujeres; con las correcciones, la infravaloración disminuyó a un 8% y un 10%, respectivamente. Se identificó una concordancia moderada para las medidas autoinformadas y una concordancia sustancial para las medidas corregidas, cuando se compararon con las medidas reales. El uso de ecuaciones de corrección para dados autoinformados se mostró un método útil para producir estimaciones más fidedignas de la prevalencia de exceso de peso y obesidad en la población general, generalmente estimadas a partir de medidas de peso y estatura autoinformadas en las encuestas poblacionales.

Resumo: O objetivo foi avaliar o efeito da exposição e do tempo de exposição ao aleitamento materno na ocorrência de transtornos mentais comuns (TMC) entre adolescentes escolares brasileiros. Este trabalho analisou dados do Estudo de Riscos Cardiovasculares em Adolescentes (ERICA), avaliando aqueles que tiveram o questionário referente ao aleitamento materno respondido pelos pais ou responsáveis. A presença de TMC foi identificada pelo General Health Questionnaire, versão 12 itens (GHQ-12), considerando-se dois pontos de corte (escores ≥ 3 e ≥ 5). As associações foram testadas em análises bivariadas e por meio de modelos de regressão logística múltipla, com ajustes por variáveis potenciais de confusão. Dentre os 41.723 adolescentes avaliados, a maioria foi composta por estudantes do sexo feminino (54,6%), que tinham idades entre 12 e 15 anos (71%), estudavam em escolas públicas (83,1%), residiam na Região Sudeste (51,9%) e eram das classes econômicas B (53,8%) e C (34,1%). Cerca de metade das mães dos adolescentes não tinha o ensino médio completo (51,7%). O grupo de adolescentes com mais de seis meses de aleitamento materno (51,8%) apresentou uma menor prevalência de TMC para os dois pontos de corte do GHQ-12 avaliados, quando comparado com o grupo que não recebeu aleitamento materno ou que o recebeu por período ≤ 1 mês (RI = 0,82; IC95%:0,69-0,97 e RI = 0,74; IC95%: 0,59-0,91 para 3 e 5 pontos, respectivamente). O aleitamento materno prolongado parece desempenhar um papel protetor para a ocorrência de TMC na adolescência.

Abstract: This article sought to evaluate the effect of exposure, and exposure time, to breastfeeding on the occurrence of common mental disorders (CMD) among Brazilian adolescents enrolled in school. This study analyzed data from the Study of Cardiovascular Risk in Adolescents (ERICA), evaluating those whose questionnaire regarding breastfeeding had been filled out by parents or guardians. The presence of CMD was identified using the General Health Questionnaire, version 12 items (GHQ-12), and we considered two cutoff points (scores ≥ 3 and ≥ 5). We tested the associations in bivariate analyses and through multiple logistical regression models, adjusting for potential confounding variables. Of the 41,723 adolescents we evaluated, most were students of the female sex (54.6%), aged between 12 and 15 years (71%), attended public schools (83.1%), resided in the Southeastern region (51.9%) and belonged to the economic classes B (53.8%) and C (34.1%). Around half of the adolescents’ mothers had not completed their secondary education (51.7%). The group of adolescents who were breastfed for more than six months (51.8%) had a lower CMD prevalence for both GHQ-12 cutoff points, when compared with the group who were not breastfed or who were breastfed for ≤ 1 month (IR = 0.82; 95%CI: 0.69-0.97 and IR = 0.74; 95%CI: 0.59-0.91 for 3 and 5 points, respectively). Prolonged breastfeeding seems to play a protective role on the occurrence of CMD in adolescence.

Resumen: El objetivo fue evaluar el efecto de la exposición y del tiempo de exposición a la lactancia materna en la ocurrencia de trastornos mentales comunes (TMC) entre adolescentes escolares brasileñas. Este trabajo analizó datos del Estudio de Riesgos Cardiovasculares en Adolescentes (ERICA), evaluando aquellos, cuyo cuestionario -referente a la lactancia materna- había sido respondido por los padres o responsables legales. La presencia de TMC fue identificada por el General Health Questionnaire, versión 12 ítems (GHQ-12), considerándose dos puntos de corte (puntuaciones ≥ 3 y ≥ 5). Las asociaciones fueron probadas en análisis bivariados, y a través de modelos de regresión logística múltiple, con ajustes por variables potenciales de confusión. Entre los 41.723 adolescentes evaluados, la mayoría estuvo compuesta por estudiantes que eran del sexo femenino (54,6%), que tenían una edad entre 12 y 15 años (71%), estudiaban en escuelas públicas (83,1%), residían en la región Sudeste (51,9%) y eran de las clases económicas B (53,8%) y C (34,1%). Cerca de la mitad de las madres de los adolescentes no contaba con la enseñanza media completa (51,7%). El grupo de adolescentes con más de seis meses de lactancia materna (51,8%) presentó una menor prevalencia de TMC para los dos puntos de corte del GHQ-12 evaluados, cuando se comparan con el grupo que no recibió lactancia materna o que la recibió durante un período ≤ 1 mes (RI = 0,82; IC95%: 0,69-0,97 y RI = 0,74 y IC95%: 0,59-0,91 para 3 y 5 puntos, respectivamente). La lactancia materna prolongada parece desempeñar un papel protector para la ocurrencia de TMC en la adolescencia.

O grupo de adolescentes com mais de seis meses de aleitamento materno (51,8%) apresentou uma menor prevalência de TMC para os dois pontos de corte do GHQ-12 avaliados, quando comparado com o grupo que não recebeu aleitamento materno ou que o recebeu por período ≤ 1 mês (RI = 0,82; IC95%:0,69-0,97 e RI = 0,74; IC95%: 0,59-0,91 para 3 e 5 pontos, respectivamente). O aleitamento materno prolongado parece desempenhar um papel protetor para a ocorrência de TMC na adolescência.

Abstract: This article sought to evaluate the effect of exposure, and exposure time, to breastfeeding on the occurrence of common mental disorders (CMD) among Brazilian adolescents enrolled in school. This study analyzed data from the Study of Cardiovascular Risk in Adolescents (ERICA), evaluating those whose questionnaire regarding breastfeeding had been filled out by parents or guardians. The presence of CMD was identified using the General Health Questionnaire, version 12 items (GHQ-12), and we considered two cutoff points (scores ≥ 3 and ≥ 5). We tested the associations in bivariate analyses and through multiple logistical regression models, adjusting for potential confounding variables. Of the 41,723 adolescents we evaluated, most were students of the female sex (54.6%), aged between 12 and 15 years (71%), attended public schools (83.1%), resided in the Southeastern region (51.9%) and belonged to the economic classes B (53.8%) and C (34.1%). Around half of the adolescents’ mothers had not completed their secondary education (51.7%). The group of adolescents who were breastfed for more than six months (51.8%) had a lower CMD prevalence for both GHQ-12 cutoff points, when compared with the group who were not breastfed or who were breastfed for ≤ 1 month (IR = 0.82; 95%CI: 0.69-0.97 and IR = 0.74; 95%CI: 0.59-0.91 for 3 and 5 points, respectively). Prolonged breastfeeding seems to play a protective role on the occurrence of CMD in adolescence.

Resumen: El objetivo fue evaluar el efecto de la exposición y del tiempo de exposición a la lactancia materna en la ocurrencia de trastornos mentales comunes (TMC) entre adolescentes escolares brasileñas. Este trabajo analizó datos del Estudio de Riesgos Cardiovasculares en Adolescentes (ERICA), evaluando aquellos, cuyo cuestionario -referente a la lactancia materna- había sido respondido por los padres o responsables legales. La presencia de TMC fue identificada por el General Health Questionnaire, versión 12 ítems (GHQ-12), considerándose dos puntos de corte (puntuaciones ≥ 3 y ≥ 5). Las asociaciones fueron probadas en análisis bivariados, y a través de modelos de regresión logística múltiple, con ajustes por variables potenciales de confusión. Entre los 41.723 adolescentes evaluados, la mayoría estuvo compuesta por estudiantes que eran del sexo femenino (54,6%), que tenían una edad entre 12 y 15 años (71%), estudiaban en escuelas públicas (83,1%), residían en la región Sudeste (51,9%) y eran de las clases económicas B (53,8%) y C (34,1%). Cerca de la mitad de las madres de los adolescentes no contaba con la enseñanza media completa (51,7%). El grupo de adolescentes con más de seis meses de lactancia materna (51,8%) presentó una menor prevalencia de TMC para los dos puntos de corte del GHQ-12 evaluados, cuando se comparan con el grupo que no recibió lactancia materna o que la recibió durante un período ≤ 1 mes (RI = 0,82; IC95%: 0,69-0,97 y RI = 0,74 y IC95%: 0,59-0,91 para 3 y 5 puntos, respectivamente). La lactancia materna prolongada parece desempeñar un papel protector para la ocurrencia de TMC en la adolescencia.

Os objetivos deste artigo são: (i) comparar medidas autorrelatadas de peso e estatura com medidas aferidas; (ii) avaliar o impacto dessas discrepâncias sobre o índice de massa corporal (IMC) e as prevalências de sobrepeso e obesidade; e (iii) aplicar modelos de correção das medidas autorrelatadas e avaliar o grau de melhoria das medidas corrigidas produzidas pelo uso desses modelos. Realizou-se estudo transversal, com avaliação de 4.151 adultos (18 a 60 anos) participantes do Estudo Epidemiológico dos Transtornos Mentais São Paulo Megacity. Foram propostos e testados modelos de regressão linear estratificados por sexo, para a correção das medidas autorrelatadas. Para avaliar a concordância, usou-se o coeficiente de correlação intraclasse para as medidas aferidas, medidas autorrelatadas e medidas corrigidas, bem como o coeficiente kappa para as categorias de classificação do IMC. O peso autorrelatado e o IMC resultantes foram subestimados, ao passo que a estatura foi superestimada, comparados às medidas aferidas. Com todos os modelos de correção, as medidas corrigidas tornaram-se mais próximas às medidas aferidas. As prevalências de excesso de peso, quando calculadas a partir das medidas autorrelatadas, estavam subestimadas em 24% em homens e 28% em mulheres. Com as correções, a subestimativa diminuiu para 8% e 10%, respectivamente. Identificou-se concordância moderada para as medidas autorrelatadas e concordância substancial para as medidas corrigidas, quando comparadas às medidas reais. O uso de equações de correção para dados autorrelatados mostrou-se um método útil para produzir estimativas mais fidedignas da prevalência de excesso de peso e obesidade na população geral, geralmente estimadas a partir de medidas de peso e estatura autorrelatadas nos inquéritos populacionais.

The study’s objectives: compare self-report measures of weight and height with direct measures; assess the impact of these discrepancies on body mass index (BMI) and prevalence of overweight and obesity; and apply correction models to the self-report measures and assess the degree of improvement in the corrected measures produced with the use of these models. A cross-sectional study was performed, assessing 4,151 adults (18 to 60 years) participating in the São Paulo Megacity Epidemiological Study. Linear regression models stratified by sex were proposed for correction of self-reported measures. Agreement was assessed with the intraclass correlation coefficient for the direct measures, self-report measures, and corrected measures, and kappa coefficient for BMI classification categories. Self-reported weight and the resulting BMI were underestimated, while height was overestimated, compared to direct measures. With all the correction models, the corrected measures were closer to the direct measures. Prevalence rates for excess weight, calculated by self-report measures, were underestimated by 24% in men and by 28% in women; with corrections, the underestimation decreased to 8% and 10%, respectively. The results showed moderate agreement for self-report measures and substantial agreement for corrected measures compared to direct measures. The use of correction equations for self-report data proved to be a useful method for producing more trustworthy estimates of prevalence of overweight and obesity in the general population, usually estimated from self-report measures of weight and height in population surveys.

Los objetivos fueron: comparar medidas autoinformadas de peso y estatura con medidas evaluadas; evaluar el impacto de estas discrepancias sobre el índice de masa corporal (IMC) y las prevalencias de sobrepeso y obesidad; y aplicar modelos de corrección de las medidas autoinformadas y evaluar el grado de mejoría de las medidas corregidas, producidas por el uso de esos modelos. Se realizó un estudio transversal evaluando a 4.151 adultos (18 a 60 años), participantes en el Estudio Epidemiológico São Paulo Megacity. Se propusieron y probaron modelos de regresión lineal estratificados por sexo para la corrección de las medidas autoinformadas. Para evaluar la concordancia, se usó el coeficiente de correlación intraclase para las medidas evaluadas, medidas autoinformadas y medidas corregidas, y el coeficiente kappa para las categorías de clasificación del IMC. El peso autoinformado y el IMC resultantes fueron subestimados mientras la estatura fue sobrestimada, comparados con las medidas evaluadas. Con todos los modelos de corrección, las medidas corregidas se convirtieron en más cercanas a las medidas evaluadas. Las prevalencias de exceso de peso, cuando se calculan a partir de las medidas autoinformadas, estaban subestimadas en un 24% en hombres y un 28% en las mujeres; con las correcciones, la infravaloración disminuyó a un 8% y un 10%, respectivamente. Se identificó una concordancia moderada para las medidas autoinformadas y una concordancia sustancial para las medidas corregidas, cuando se compararon con las medidas reales. El uso de ecuaciones de corrección para dados autoinformados se mostró un método útil para producir estimaciones más fidedignas de la prevalencia de exceso de peso y obesidad en la población general, generalmente estimadas a partir de medidas de peso y estatura autoinformadas en las encuestas poblacionales.

Resumo Introdução: Várias meta-análises anteriores documentaram a eficácia a curto prazo da terapia cognitivo-comportamental (TCC). No entanto, sua eficácia a longo prazo permanece desconhecida. O transtorno de estresse pós-traumático (TEPT) é uma doença crônica grave, debilitante e incapacitante. Objetivo: Estimar a eficácia a longo prazo da TCC no tratamento do TEPT, avaliando a manutenção do efeito após um ano de seguimento. Métodos: Realizamos uma revisão sistemática através de pesquisas nas bases de dados eletrônicas ISI Web of Science, PubMed, PsycInfo e Pilots. Incluímos estudos randomizados nos quais a TCC foi comparada com um grupo controle (lista de espera ou tratamento usual) em adultos com TEPT que relataram pelo menos um ano de seguimento da TCC. Resultados: A pesquisa identificou 2.324 estudos e 8 foram selecionados. A TCC mostrou-se eficaz no tratamento do TEPT no período pós-tratamento. A melhora nos sintomas de TEPT foi estatisticamente significativa em relação ao grupo controle. A melhora observada no grupo de tratamento ou grupo único (formado por ambos os grupos de tratamento e controle, que foi submetido à intervenção após algumas semanas na lista de espera) foi mantida no seguimento. Conclusão: Devido à ausência de grupo controle no período de follow-up em 6 dos 8 estudos incluídos nesta revisão, ainda não há base metodológica adequada para afirmar que a TCC tem efeitos duradouros no tratamento do TEPT. Nosso estudo encontrou graves deficiências metodológicas e a necessidade de preencher essa lacuna na literatura através de estudos com delineamentos robustos e sofisticados.

Abstract Introduction: While several previous meta-analyses have documented the short-term efficacy of cognitive-behavioral therapy (CBT), its long-term efficacy remains unknown. Posttraumatic stress disorder (PTSD) is a serious, debilitating, often chronic and disabling disease. Objective: To estimate the long-term efficacy of CBT in the treatment of PTSD by assessing the maintenance of the effect after one year of follow-up. Method: We performed a systematic review through electronic database searches including ISI Web of Science, PubMed, PsycInfo and Pilots. We included randomized studies in which CBT was compared with a control group (waiting list or usual care) in adults with PTSD that reported at least one year of CBT follow-up. Results: Our search identified 2,324 studies and 8 were selected. CBT was shown to be effective in the treatment of PTSD in the post-treatment period. Improvement in PTSD symptoms was statistically significant in relation to the control group. The improvement observed in the treatment group or single group (formed by both treatment group and control group, which was submitted to the intervention after a few weeks on the waiting list) was maintained in the follow-up. Conclusion: Due to the lack of control groups in the follow-up period in six of the eight studies included in this review, there is still no proper methodological basis to assert that CBT has lasting effects in the treatment of PTSD. Our study found serious methodological shortcomings and the need to fill this gap in the literature through the development of studies with robust and sophisticated designs.

RESUMO Objetivo Este trabalho buscou caracterizar os pacientes atendidos no ambulatório geral do Instituto de Psiquiatria da Universidade Federal do Rio de Janeiro (IPUB-UFRJ) e avaliar sua estabilidade clínica. Métodos Este estudo descritivo, transversal, coletou informações utilizando um questionário estruturado preenchido pelo médico assistente. O questionário, especificamente desenvolvido para esse propósito, continha dados sociodemográficos, área de moradia, diagnóstico psiquiátrico de acordo com a CID-10, avaliação da estabilidade clínica por meio de cinco critérios de instabilidade psiquiátrica e a impressão clínica global do médico, nos últimos seis meses. A estabilidade clínica foi definida como uma resposta negativa a todos os cinco critérios de instabilidade predefinidos. Resultados No total, 1.447 questionários foram preenchidos. A amostra foi composta por 824 (57%) mulheres, com média de idade de 49 anos; 1.104 (76,3%) pacientes residentes na cidade do Rio de Janeiro e 343 (23,7%) residentes fora da cidade; 983 (67,9%) pacientes com diagnóstico de transtorno mental grave (TMG) e 946 (65,3%) pacientes foram considerados estáveis. Estatisticamente, a estabilidade clínica por área de moradia não apresentou diferenças. O critério de instabilidade mais frequente foi “recrudescimento ou o surgimento de manifestações agudas da doença”. Conclusão A maioria dos pacientes apresentava um TMG e foi considerada clinicamente estável.

ABSTRACT Objective This study aimed to characterize the patients assisted at the general outpatient clinic of the Psychiatry Institute of Universidade Federal do Rio de Janeiro (IPUB-UFRJ) and to assess these patients’ clinical stability. Methods This cross-sectional study collected information using a structured questionnaire filled in by the patient’s physician. The questionnaire, specifically developed for this purpose, included sociodemographic data; the dwelling area; psychiatric diagnosis according to ICD-10; clinical stability assessment by means of five psychiatric instability criteria and the physician’s global clinical impression over the six previous months. Clinical stability was defined as a negative answer to all five pre-defined instability criteria. Results Overall, 1,447 questionnaires were filled in. The sample was composed of 824 (57%) women; with an average age of 49 years; 1,104 (76.3%) patients lived in the city of Rio de Janeiro and 343 (23.7%) lived outside the city; 983 (67.9%) patients had a severe mental disorder (SMD) diagnosis and 946 (65.3%) patients were considered stable. Statistically, the clinical stability by dwelling area did not differ. The most frequent clinical instability criterion was “exacerbation or emergence of acute manifestations of the disease”. Conclusion The major part of the patients displayed a SMD and was considered clinically stable.
