Abstract This study aimed to evaluate trends in the prevalence of dental caries in preschool children and associated factors considering different time variations. This is a time series study performed using data from three cross-sectional studies with pre-school children from southern Brazil in 2008, 2013 and 2019. This children group was born between the years of 2003 to 2018. Dental caries was evaluated by decayed, missing and filled deciduous teeth (dmft index). Demographic, socioeconomic, behavioural and psychosocial variables were also collected. Chi-square test for trends and a hierarchical age-period-cohort (HAPC) analysis using multilevel Poisson regression model for testing the associations between predictor variables and dental caries experience were used. A total of 1,644 pre-school children participated in all surveys. There was a significant difference in caries experience considering all APC effects. The prevalence of dental caries was 25.0% in 2008, 16.3% in 2013, and 19.4% in 2019 (p < 0.01) and no statistical difference was observed. An age effect showed that older children were more likely to experience dental caries. Considering the cohort effect, there is a significant difference between the generations, mainly between 2003 and 2018. Household income, use of dental services, and parent’s perception of child oral health were associated with dental caries experience no matter the time variation. Despite recent declines in dental caries prevalence among preschool children, caries levels increased with age and social inequalities persisted through the years, indicating a need of reviewing the policies to reduce the burden of this oral disease. variations crosssectional cross sectional pre school 2008 201 200 2018 decayed dmft index. index . index) Demographic socioeconomic collected Chisquare Chi square ageperiodcohort period HAPC (HAPC used 1644 1 644 1,64 surveys effects 250 25 0 25.0 163 16 3 16.3 194 19 4 19.4 p 0.01 001 01 observed generations income services parents parent s variation disease 20 164 64 1,6 2 25. 16. 19. 0.0 00 6 1, 0.

Abstract This study aimed to explore the pathways that can influence cigarette smoking among adolescents. This population-based cohort followed a random sample of 12-year-old adolescents from southern Brazil for 6 years. Regular cigarette smoking was assessed through a self-reported question, previously used in the Brazilian National Survey of Scholar Health. We also gathered data on bullying, dental caries at baseline, incidence of caries, sex, friend network, and Sense of Coherence (SOC). Socioeconomic and demographic characteristics were also collected. Structural equation modeling was used to evaluate the pathways. Of the 1,134 adolescents examined at baseline, 768 were re-evaluated (67.7% retention rate). The prevalence of smoking was 37.6%. This prevalence was directly affected by low SOC (SC: -0.14, p < 0.01), low household income (SC: -0.12, p < 0.01), and male sex (SC: 0.15, p < 0.01). Presence of dental caries at baseline indirectly influenced the occurrence of dental bullying at follow-up via the incidence of dental caries (SC: 0.01, p < 0.05). Dental bullying indirectly influenced cigarettes consumption via SOC (SC: 0.62, p < 0.05). Friend network also indirectly influenced the consumption of cigarettes via SOC (SC: 0.32, p < 0.05). Psychosocial factors influence adolescent cigarette consumption through its higher direct and indirect effects (via bullying). In addition, behavioral, sociodemographic, and clinical factors also influence the occurrence of smoking. populationbased population based 12yearold yearold 12 year old years selfreported self reported question Health SOC. .

Resumo Este estudo teve como objetivo avaliar a influência do número de cirurgiões-dentistas do bairro na incidência de cárie dentária na dentição permanente. Esta coorte teve início em 2010 (T1) com uma amostra aleatória de 639 crianças (1 a 5 anos) acompanhadas por 7 anos, no sul do Brasil. A reavaliação (T2) ocorreu em 2017. A cárie dentária não tratada foi avaliada no T2 por meio do índice de superfícies cariadas, perdidas e obturadas (CPO-S). O número de dentistas do bairro foi obtido no banco de dados oficial da cidade e usada como uma variável contextual. Variáveis socioeconômicas, demográficas e de saúde bucal no nível individual foram avaliadas no T1. Foi realizada uma análise de regressão de Poisson multinível para avaliar a influência das variáveis preditoras na incidência de cárie dentária não tratada. Das 639 crianças no T1, 449 foram reavaliadas no T2 (taxa de retenção de 70,3%). A média das superfícies cariadas no T2 foi de 0,92 (EP 0,01). Quanto maior o número de dentistas nos bairros em que as crianças residiam, menor era a incidência de cárie dentária. Crianças com baixo nível socioeconômico, que não consultaram rotineiramente o dentista nos últimos 6 meses, que apresentaram experiência de cárie dentária e cujos pais perceberam sua saúde bucal como regular/ruim apresentaram maior incidência de superfícies com cárie dentária não tratada. Como conclusão, crianças que moram em bairros com menos dentistas têm maior incidência de cárie não tratada na dentição permanente.

Abstract This study aimed to evaluate the influence of the number of dentists in the neighborhood on the incidence of dental caries in the children permanent dentition. This cohort began in 2010 (T1) with a random sample of 639 children (1 to 5 years-old) followed for 7 years, in southern Brazil. The follow-up reassessment (T2) took place in 2017. Untreated dental caries was evaluated at T2 through the Decayed, Missing, and Filled surfaces index (DMF-S). The number of dentists in the neighborhood was obtained from the city’s official database and used as a contextual variable. Socioeconomic, demographic, and oral health variables at the individual level were evaluated at T1. A multilevel Poisson regression was performed to evaluate the influence of the predictor variables in the incidence of untreated dental caries. From 639 children at T1, 449 were reassessed at T2 (a 70.3% retention rate). The mean of decayed surfaces at T2 was 0.92 (SE 0.01). The greater the number of dentists in the neighborhoods where the children lived, the lower the incidence of dental caries. Children with low socioeconomic status, who have not routinely visited the dentist in the last 6 months, who presented a experience of dental caries, and whose parents perceived their oral health as fair/poor showed a higher incidence of surfaces with untreated dental caries. As conclusion, children who live in neighborhoods with fewer dentists have a higher incidence of untreated dental caries in permanent dentition.

Abstract: This study evaluated the influence of Oral Health-Related Quality of Life (OHRQoL) on the consumption of alcohol and cigarette use in adolescents. This prospective cohort began in 2012 (T1) with an initial random sample of 1134 12-year-old adolescents followed for 6 years in Santa Maria, southern Brazil. The present study comprised data from the two cohort reassessments that took place in 2014 (T2) and 2018 (T3). OHRQoL was measured with the Brazilian short version of the Child Perceptions Questionnaire (CPQ11-14) at T2. Socioeconomic, demographic, and oral health measures were also collected during this period. Alcohol and cigarette consumption (regular use) in the past 30 days was evaluated at T3 through questions in the of the National School Health Survey (PeNSE) questionnaire. A multilevel Poisson regression model was used to evaluate the influence of predictor variables on substance use. Of the 770 adolescents at T2, 575 and 576 adolescents were reassessed at T3 for alcohol and cigarette consumption, respectively. Adolescents with higher overall CPQ11-14 scores were at higher risk for regular consumption of alcohol (IRR 1.01; 95% CI 1.01-1.02) and cigarette (IRR 1.04; 95% CI 1.03-1.05). Non-white adolescents with low socioeconomic status, untreated dental caries, and who had not been to the dentist (last 6 months) were also associated with increased regular consumption of licit substances. Adolescents with worse OHRQoL presented a higher consumption of alcohol and cigarette. These findings are useful for planning public health strategies to improve adolescent OHRQoL and reduce the harmful substance use.

ABSTRACT Surgical patients with gastrointestinal cancer often suffer from malnutrition. This study aimed to evaluate the influence of fasting time on the nutritional status of patients hospitalized with preoperative and postoperative gastrointestinal tract neoplasms. Observational, longitudinal, and prospective study conducted in the surgical unit at a public-school hospital. The patients were divided into groups: upper (UGIT) and lower (LGIT) gastrointestinal tract. Follow-up started within 72 h of hospitalization with reassessment 72 h after surgery. Data collected: sex, age, type and duration of surgery, preoperative (compared with 8 h) and postoperative (compared with 24 h) fasting time, food acceptance, Subjective Global Assessment, anthropometry, and laboratory tests. Analyses: Student t, Wilcoxon, and chi-square tests. Fifty-one patients were followed up, 29 (57%) UGIT and 22 (43%) LGIT. The preoperative fasting time was 8.2±2.8 h in UGIT and 8.1±2.2 h in LGIT groups, respectively; however, postoperative fasting times in UGIT (60.4±40.7 h) and LGIT groups (57.6±38.2 h) were longer than 24 h (P<0.001). Although eutrophic in the preoperative period, in the postoperative most patients in the UGIT and LGIT groups presented, respectively, malnutrition (71%; 59%; P<0.001), severe weight loss (79%; 80%), a significant correlation between triceps skinfold and postoperative fasting time (r= -0.306; P= 0.03), and hemoglobin and albumin values (r= 0.633; P<0.001), additionally low dietary acceptance, especially in the UGIT group. Prolonging postoperative fasting time worsened the nutritional status of surgical patients, especially in the UGIT group.

RESUMEN Los pacientes quirúrgicos con cáncer gastrointestinal a menudo sufren desnutrición. El objetivo de este estudio fue evaluar la influencia del tiempo de ayuno en estado nutricional de pacientes hospitalizados con neoplasias del tracto gastrointestinal preoperatorio y posoperatorio. Estudio observacional, longitudinal y prospectivo realizado en unidad quirúrgica de un hospital escolar público. Los pacientes fueron divididos en grupos: tracto gastrointestinal superior (UGIT) y inferior (LGIT). El seguimiento se inició dentro del 72 h de la hospitalización con reevaluación 72 h después de la cirugía. Datos recolectados: sexo, edad, tipo y duración de la cirugía, tiempo de ayuno preoperatorio (comparado con 8 h) y postoperatorio (comparado con 24 h), aceptación de dieta, Evaluación Subjetiva Global, antropometría y pruebas de laboratorio. Análisis: pruebas de T, Wilcoxon y chi-cuadrado. Se siguió 51 pacientes, 29 (57%) en UGIT y 22 (43%) en LGIT. El tiempo de ayuno preoperatorio fue 8,2±2,8 h (UGIT) y 8,1±2,2 h (LGIT); sin embargo, los tiempos de ayuno posoperatorio en UGIT (60,4±40,7 h) y LGIT (57,6±38,2 h) fueron superiores a 24 h (P<0,001). Aunque eutróficos en preoperatorio, en postoperatorio la mayoría de los pacientes (UGIT y LGIT, respectivamente) presentaron desnutrición (71%; 59%; P<0,001), pérdida de peso severa (79%; 80%), correlación significativa entre pliegue cutáneo del tríceps y tiempo de ayuno posoperatorio (r= -0.306; P= 0.03), valores de hemoglobina y albúmina (r= 0,633; P<0,001), y baja aceptación de dieta, especialmente del UGIT. La prolongación del ayuno postoperatorio empeoró el estado nutricional de los pacientes quirúrgicos, especialmente del UGIT.

ABSTRACT Objective: To evaluate the intake of micronutrients with antioxidant properties through exclusive enteral nutrition therapy (ENT) in hospitalized patients with chronic diseases compared to the estimated average requirement (EAR). Methods: This prospective, longitudinal, descriptive, observational study was performed in a public hospital, with adult and elderly patients. The adequacy of the volume of ENT prescribed and offered was considered satisfactory when >80%. The adequacy of micronutrients with antioxidant properties was performed according to the estimated average need (EAR). Data were considered statistically significant when p<0.05. Results: Of the 53 included patients, 58.5% were male. Most of patients (45.3%) were in the neurology clinic, and the main cause was cerebral vascular accident (18.9%). The volume administered was less than the prescribed volume of ENT in both male and female patients. However, recommendations for micronutrients with antioxidant properties, such as vitamin A, vitamin C, vitamin E, zinc, selenium, copper and iron, are according to EAR and did not exceed the tolerable intake limit (upper limit, UL), (p<0.05). The present study shows a very large variability in the concentration of micronutrients in each enteral diet. It is necessary to consider the pathologies that affect the patient, as some health conditions may be able to require specific amounts of micronutrients. Conclusions: Patients received a lower volume of enteral nutrition therapy compared to the prescribed volume. The micronutrient concentrations were consistent with daily EAR recommendations and did not exceed the tolerable intake limit (UL) for healthy individuals.

RESUMEN Objetivo: Evaluar la ingesta de micronutrientes con propiedades antioxidantes a través de la terapia de nutrición enteral exclusiva (ENT) en pacientes hospitalizados con enfermedades crónicas en comparación con el requerimiento promedio estimado (RPE). Métodos: Prospectivo, longitudinal, descriptivo y de observación, se realizó en un hospital público con pacientes adultos y ancianos. La adecuación del volumen de ENT prescrito y ofrecido se consideró satisfactoria cuando fue >80%. La adecuación de micronutrientes con propiedades antioxidantes se realizó de acuerdo con la RPE. Se consideraron estadísticamente significativos p<0,05. Resultados: De los 53 pacientes incluidos, 58,5% eran hombres. La mayoría de los pacientes (45,3%) se encontraban en la consulta de neurología y la principal causa fue el accidente vascular cerebral (18,9%). El volumen administrado fue menor que el volumen prescrito de ENT tanto en pacientes masculinos como femeninos. Sin embargo, las recomendaciones de micronutrientes con propiedades antioxidantes, como vitamina A, vitamina C, vitamina E, zinc, selenio, cobre y hierro, están de acuerdo con la RPE y no superan el límite de ingesta tolerable (UL), (p<0,05). El presente estudio muestra una variabilidad muy grande en la concentración de micronutrientes en cada dieta enteral. Es necesario considerar las patologías que afectan al paciente, ya que algunas condiciones de salud pueden requerir cantidades específicas de micronutrientes. Conclusiones: Los pacientes recibieron un volumen menor de ENT en comparación con el volumen prescrito. Las concentraciones de micronutrientes fueron consistentes con las recomendaciones diarias de la RPE y no excedieron el límite de ingesta tolerable (UL) para individuos sanos.

Trata-se de uma revisão integrativa de literatura que teve como objetivo identificar as evidências acerca dos fatores geradores de sobrecarga e suas consequências para os familiares cuidadores de adultos ou idosos. A revisão abrangeu 27 estudos em base de dados, com as palavras-chave cuidadores, família e sobrecarga, no período de 1999 a 2009. Foram desveladas quatro categorias: a imposição de ser o cuidador, o cuidar solitário, a dependência do ser cuidado e o desgaste biopsicossocial do cuidador. Os resultados demonstram que a imposição do papel de cuidador, a falta de apoio dos outros familiares, o grau de dependência do enfermo relacionada à patologia, e o desgaste físico e psicológico são os principais fatores geradores de sobrecarga dos familiares cuidadores. Verifica-se a necessidade de maior suporte dos profissionais de saúde no sentido de apoiar e estar disponível aos familiares cuidadores nas intercorrências das atividades cuidativas no domicílio.

This is an integrative literature review that aims to identify evidences on the factors causing overload and their consequences for family caregivers of adults or the elderly. The review covered 27 studies at databases, using the keywords caregivers, family, and overload, in the period from 1999 to 2009. Four categories came up: the imposition of being a caregiver, taking care alone, the dependence of the person that receives care, and the bio-psychosocial weariness of the caregiver. The results showed that the imposition of the role of caregiver, lack of support from other family members, level of dependency of the patient related to the pathology, and physical and psychological weariness are the main factors causing overload in family caregivers. The need for more support and availability by health professionals to family caregivers in their home activities is evident.

Se trata de una revisión integradora de la literatura dirigida a identificar la evidencia de los factores que causan sobrecarga y sus consecuencias para los familiares cuidadores de adultos o ancianos. La revisión abarcó 27 estudios en base de datos con los descriptores cuidadores, familia y sobrecarga, de 1999 a 2009. Cuatro categorías se desvelaron: la imposición de ser el cuidador, el cuidado solitario, la dependencia del ser cuidado y el desgaste biopsicosocial del cuidador. Los resultados muestran que la imposición del rol de cuidador, la falta de apoyo de otros familiares, el grado de dependencia del enfermo relacionado con la patología y el desgaste físico y psicológico son los principales factores generadores de sobrecarga de familiares cuidadores. Se constata la necesidad de mayor soporte de profesionales de la salud para apoyar y estar a disposición de los familiares cuidadores en las complicaciones de las actividades cuidadoras en hogar.
