Objective: To evaluate the association between dietary patterns and mental disorders among pregnant women in southern Brazil. Methods: Cross-sectional study with 712 pregnant women recruited from the Study of Food Intake and Eating Behaviors in Pregnancy (ECCAGe). Food intake assessment was performed using the Food Frequency Questionnaire. Dietary patterns were identified by cluster analysis. The Primary Care Evaluation of Mental Disorders (PRIME-MD) was used to evaluate participants’ mental health. Poisson regression models with robust variance were fitted to estimate prevalence ratios (PR). Results: In the adjusted models, there was a high prevalence of major depressive disorder among women with low fruit intake (43%, PR 1.43, 95%CI 1.04-1.95) and high sweets and sugars intake (91%, PR 1.91, 95%CI 1.19-3.07). Women with a common-Brazilian dietary pattern had higher prevalence of major depressive disorder compared to those with a varied consumption pattern (PR 1.43, 95%CI 1.01-2.02). Low intake of beans was significantly associated with generalized anxiety disorder (PR 1.40, 95%CI 1.01-1.93). Conclusions: Low consumption of fruits and beans and intake of the common-Brazilian dietary pattern during pregnancy were associated with higher prevalence of mental disorders. These results reinforce the importance of an adequate dietary intake to ensure better mental health in pregnancy.

Objective: To assess the prevalence of common mental disorders (CMD) and the association of CMD with sociodemographic characteristics in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) cohort. Methods: We analyzed data from the cross-sectional baseline assessment of the ELSA-Brasil, a cohort study of 15,105 civil servants from six Brazilian cities. The Clinical Interview Schedule-Revised (CIS-R) was used to investigate the presence of CMD, with a score ≥ 12 indicating a current CMD (last week). Specific diagnostic algorithms for each disorder were based on the ICD-10 diagnostic criteria. Prevalence ratios (PR) of the association between CMD and sociodemographic characteristics were estimated by Poisson regression. Results: CMD (CIS-R score ≥ 12) was found in 26.8% (95% confidence intervals [95%CI] 26.1-27.5). The highest burden occurred among women (PR 1.9; 95%CI 1.8-2.0), the youngest (PR 1.7; 95%CI 1.5-1.9), non-white individuals, and those without a university degree. The most frequent diagnostic category was anxiety disorders (16.2%), followed by depressive episodes (4.2%). Conclusion: The burden of CMD was high, particularly among the more socially vulnerable groups. These findings highlight the need to strengthen public policies aimed to address health inequities related to mental disorders.

O Grupo de Trabalho em Diabetes e Gravidez, reunido durante o XI Congresso Brasileiro de Diabetes, em 1997, elaborou normas para o manejo do diabetes gestacional e pré-gestacional. O rastreamento do diabetes gestacional deve ser seletivo, isto é, dirigido a gestantes com fatores de risco. Para tanto, é sugerido o emprego da glicemia de jejum a partir da 20ª semana de gestação. Pontos de corte de 85mg/dl ou 90mg/dl são sugeridos para classificação de rastreamento positivo, que indica a necessidade de um teste oral de tolerância com 75g de glicose. Esse teste deve ser interpretado de acordo com os critérios sugeridos pela Organização Mundial da Saúde (glicemia de jejum ³126mg/dl ou glicemia de 2h ³140mg/dl). São apresentadas também estratégias de manejo metabólico e obstétrico do diabetes gestacional e do diabetes pré-gestacional.

Clinical guidelines for the management of gestational diabetes and pregestational diabetes were prepared by the Diabetes and Pregnancy Working Group, during the XI Brazilian Diabetes Congress, held in 1997. Selective screening of pregnant women based on the presence of risk factors is advised beginning at the 20th week of gestation, using a fasting plasma glucose. Cut points of 85mg/dl or 90mg/dl are used to classify a positive screening. A 75g oral glucose tolerance test is performed if the screening test is positive. Diagnostic cut points suggested by the World Health Organization are endorsed (fasting plasma glucose ³126mg/dl or 2h plasma glucose ³140mg/dl). Endocrine and obstetric management of gestational diabetes as well as a review on pre-gestational diabetes management are also presented.

Para avaliar a validade do peso auto-referido em inquéritos de prevalência de obesidade, o mesmo foi comparado com o peso medido de 659 adultos, residentes em Porto Alegre, RS, Brasil, em 1986-87. Ambos os pesos foram obtidos por entrevistador, na casa do participante, na mesma ocasião. A média das diferenças entre peso auto-referido e peso medido foi pequena (-0,06 +/-3,16 kg; média +/- desvio padrão) e a correlação entre eles alta (r=0,97). Sessenta e dois por cento dos participantes referiram seu peso com erro < 2 kg, 87% com erro menor do que 4 kg e 95% com erro < 6 kg. Indivíduos de baixo peso hiperestimaram seu peso, o oposto ocorrendo com indivíduos obesos (p<0,05). Os homens tendiam a superestimar seu peso, o oposto ocorrendo com as mulheres (p=0,04). A prevalência geral de baixo peso (índice de massa corporal (IMC) < 20) por peso auto-referido foi de 11% e a por peso medido, de 13%; a prevalência geral de obesidade (IMC > 30) por peso referido, foi de 10% e a por peso medido, de 11%. Concluindo, a validade do peso auto-referido é aceitável para inquéritos de prevalência realizados em contextos similares.

In order to evaluate the validity of self-reported weight for use in obesity prevalence surveys, self-reported weight was compared to measured weight for 659 adults living in the Porto Alegre county, RS Brazil in 1986-87, both weights being obtained by a technician in the individual's home on the same visit. The mean difference between self-reported and measured weight was small (-0.06 +/- 3.16 kg; mean +/- standard deviation), and the correlation between reported and measured weight was high (r=0.97). Sixty-two percent of participants reported their weight with an error of < 2 kg, 87% with an error of < 4 kg, and 95% with an error of < 6 kg. Underweight individuals overestimated their weight, while obese individuals underestimated theirs (p<0.05). Men tended to overestimate their weight and women underestimate theirs, this difference between sexes being statistically significant (p=0.04). The overall prevalence of underweight (body mass index < 20) by reported weight was 11%, by measured weight 13%; the overall prevalence of obesity (body mass index > 30) by reported weight was 10%, by measured weight 11%. Thus, the validity of reported weight is acceptable for surveys of the prevalence of ponderosity in similar settings.

Três quartos da mortalidade no Estado do Rio Grande do Sul (Brasil) ocorrem por doenças não-transmissíveis. Dentre elas as doenças cardiovasculares, por si só, correspondem a 35% das causas de morte. Para avaliar a prevalência de fatores de risco para essas doenças, foi realizado inquérito domiciliar no período de 1986/87. Foram entrevistados 1.157 indivíduos entre 15-64 anos, residentes em setores censitários de 4 áreas docente-assistenciais do Município de Porto Alegre, RS. A prevalência padronizada de tabagismo foi de 40%, hipertensão 14%, obesidade 18%, sedentarismo geral 47% e consumo excessivo de álcool, 7%. Trinta e nove por cento da amostra acumulavam dois ou mais desses cinco fatores de risco, somente 22% de homens e 21% de mulheres não apresentaram esses fatores de risco. As elevadas freqüências e concomitâncias desses fatores de risco alertam para sua importância em programas que visam a prevenção das doenças não-transmissíveis.

Three-quarters of deaths in Rio Grande do Sul State, Brazil, are due to non-communicable diseases - cardiovascular diseases, alone, being responsible for 35% of them. To evaluate the prevalence of risk factors for these diseases, a household survey of 1,157 randomly sampled individuals between 15 and 64 years of age was undertaken in 1986 and 1987 in census tracts of 4 areas of the city of Porto Alegre. The age-and sex-adjusted prevalence of smoking was 40%, hypertension 14%, obesity 18%, overall sedentary lifestyle 47%, and excessive alcohol consumption 7%. Thirty-nine percent of the sample presented two or more of these five risk factors, and only 22% of men and 21% of women had none of them. The high frequencies and simultaneous presence of these risk factors indicate their importance for programs aimed at the prevention of non-communicable diseases and the promotion of adult health.
