    ABSTRACT: Association between three physical activity (PA) measurements throughout adolescence and bone density at 18 years of age was investigated. PA was associated with both lumbar spine and femoral neck bone mineral density (BMD) in early adulthood independent of type of PA used in the analysis. The results were more consistent in boys. This study amis to evaluate if PA during adolescence could influence BMD later in life. A population-based birth cohort study was carried out. PA was assessed at 11 and 15 years of age by questionnaire and included sports performed while BMD (lumbar spine and femoral neck) was measured by dual-energy X-ray absorptiometry at 18 years. A peak strain score was generated based on ground reaction forces of different PA. PA was measured as peak strain score, peak strain score multiplied by minutes/week and minutes/week. Unadjusted and adjusted analyses were performed using linear regression. Overall, 3,811 adolescents were studied (1,866 boys and 1,945 girls). The peak strain score at 11 and 15 years was associated with lumbar and femoral neck BMD at 18 years in boys. Among girls, high-impact PA at 11 years was positively associated with lumbar and femoral BMD (p = 0.01; p < 0.001). After adjusted analysis, weekly minutes of PA at 11 years were not associated with lumbar spine but were associated with femoral neck BMD (p < 0.001); at 15 years, weekly minutes of PA were positively associated with BMD at both sites. Regardless of PA status at 11 years of age, attaining the recommendations of PA (300 min/week) at 15 years appears to be important for BMD at 18 years in both sites in boys and girls. The results Appeared to be more consistent in boys. PA during adolescence was positively associated with both lumbar spine and femoral neck BMD in early adulthood independent of type of PA used in the analysis.

    ABSTRACT: To estimate the point prevalence of self-medication among adolescents aged 18 years and to evaluate the type of drugs used (either over-the-counter or prescription drugs) and socioeconomic, health-related, and behavioral correlates of self-medication. This cross-sectional study used data from the 1993 Pelotas (Brazil) Birth Cohort Study. Data were obtained through the administration of a questionnaire to adolescents aged 18 years. The outcome variables were point prevalence of medicine use and self-medication collected by self-report. The independent variables studied were gender, continuous medicine use, socioeconomic status, schooling, self-rated health, body mass index, and physical activity levels. Medicines were classified into therapeutic groups according to the Anatomical Therapeutic Chemical classification system. A total of 4,106 adolescents were interviewed. The point prevalence of medicine use was 41.1% (95% confidence interval [CI] 39.6-42.6), and the proportion of self-medication among medicine users was 65.1% (95% CI 62.8-67.4). The point prevalence of self-medication was 26.7% (95% CI 25.4-28.1), and it was higher among female adolescents, those more educated, and those who rated their health as poor. Out of the drugs used for self-medication (58% of all drugs used), 1,003 (78.7%) were nonprescription drugs and 271 (21.3%) were prescription drugs. The most frequently used drugs for self-medication were analgesics (56.1%), systemic antihistamines (7.4%), and anti-inflammatory and antirheumatic products (7.1%). A high point prevalence of self-medication was found among adolescents, which is particularly concerning due to high use of prescription drugs for self-medication. Interventions are needed to promote rational use of medicines in this population.

    ABSTRACT: This study aimed to describe dietary patterns and to investigate associations with demographic and socioeconomic factors among children one to six years of age in the city of Pelotas, Rio Grande do Sul State, Brazil. Pearson correlation was used to group different foods. Dietary patterns were constructed using principal components analysis (PCA). Associations were established with the Kruskal Wallis test (α = 0.05). The study evaluated 667 children. Five dietary patterns were identified: "vegetables", "traditional" (bread, butter/margarine, rice/pasta, coffee, sugar), "sweets and sausages", "snacks" (dairy products, chocolate, cookies, and juice), and "fruits". Children of mothers with more schooling and higher income showed greater adherence to "vegetables" and "fruits". The "traditional" pattern was more common in children of mothers with less education and lower family income. The "vegetables" and "traditional" patterns showed greater variance. Families' socioeconomic status played a key role in determining children's dietary patterns.

    ABSTRACT: The aim of this study was to analyze the effect of lifestyle counseling on metabolic syndrome (MetS) prevalence in the short term. This was a before-after study design conducted in a nutrition outpatient clinic. Participants were adults presenting with MetS according to the International Diabetes Federation criteria. In the study 109 individuals (mean age 41 ± 9.6 years old) were included, the majority women (82,6%). Participants received individualized dietary prescription guidelines for healthy eating and were encouraged to perform physical activity. After five months, a decrease of 21.5% in the prevalence of MetS (p<0,001) was observed Significant mean reductions (p<0,001) in bodyweight (3.5 ± 3.4 Kg), waist circumference (4.0 ± 4.0 cm), triglycerides (33.8 ± 69.6 mg/dl) and fasting glucose we observed (6.6 ± 18.3 mg/dl), while HDL cholesterol showed an increase (2.6 ± 6.1mg/ dl, p<0,001). We conclude that lifestyle counseling consisting of individualized nutritional guidance through a balanced diet, physical activity promotion and change in lifestyle can reduce the prevalence of MetS in the short term.

    ABSTRACT: This study evaluated the association between obesity and emotional and behavioral difficulties in adolescents. We studied 4,325 individuals 11 to 15 years of age who were members of the 1993 birth cohort in Pelotas, Rio Grande do Sul State, Brazil. Information on body mass index (BMI), maternal assessment of the adolescents' emotional and behavioral health (Strengths and Difficulties Questionnaire - SDQ), and sociodemographic and behavioral characteristics were used. Gender-stratified analyses were conducted with simple and multivariate linear regression. In the adjusted analysis, obesity only correlated with total SDQ scores in boys. Among the latter, teenage obesity was associated with higher scores on the subscale of relational problems with peers. Given current knowledge on the future implications of obesity and mental health and in dealing with adolescents, studies on gender differences in adolescence may contribute to understanding such associations.

    ABSTRACT: Early childhood nutritional factors can play a crucial role in the development of body composition in later phases of life. A systematic literature review was conducted to identify studies on the association between early nutritional determinants and fat-free mass in adulthood. The PubMed and Virtual Health Library electronic databases were used. Nine articles were included after a peer review of the 576 references initially found, published from 2003 to 2009, with healthy subjects and longitudinal analysis. Birth weight and birth length and variations across childhood were strong predictors of fat-free mass at later ages. The studies showed that higher birth weight and greater weight gain in early childhood were associated with greater fat-free mass in adulthood. However, the available data are limited and inconclusive in relation to eating in early childhood as a predictor of fat-free mass at later ages.

    ABSTRACT: The aim of this study was to characterize the methodology of data collection on physical activity using accelerometry in two birth cohorts (2004 and 1993) in Pelotas, Rio Grande do Sul State, Brazil, at the 6-7 and 18-year follow-up visits, respectively. During visits to the study headquarters for a health evaluation, cohort subjects received the accelerometer to be worn on the wrist for 5 to 8 days, after which the device was retrieved at their homes. Genea and GENEActiv triaxial estimators of gravity (g) acceleration were employed. Accelerometry data were collected from 3,331 children (93.7% of those included in follow-up) and 3,816 adolescents (99% of those in follow-up). The study characterizes the data collection methodology in more than 7,000 individuals and discusses issues in its implementation. It thus provides a methodological framework aimed at helping to plan future population-based studies with the use of such technology and to improve understanding of physical activity in the context of epidemiological studies.

    ABSTRACT: Prenatal cigarette smoke exposure may have adverse psychological effects on offspring. The objective was to assess the association between parental smoking during pregnancy and offspring happiness at age 18, as well as depression. Participants were part of a birth cohort study in Pelotas, Brazil (5,249 participants). Happiness was measured by the Subjective Happiness Scale, a Likert-like scale with four questions generating a score from 1 to 7, with ≥ 6 indicating "happiness". Depression was measured using the Mini International Psychiatric Interview. About one third of mothers reported having smoked during pregnancy and 4.6% reported smoking 20 or more cigarettes a day. The prevalence of happiness was 32.2% (95% CI 30.8; 33.7), depression 6.8% (95% CI 6.1; 7.6), and simultaneous happiness and depression less than 1%. The prevalence of offspring happiness decreased as smoking in pregnancy increased, even after control for confounding variables, showing an OR = 0.79 [95% CI 0.55; 1.13]. The opposite happened to depression; the prevalence of offspring depression increased as smoking in pregnancy increased (<20 cigarettes/day OR = 1.38 [95% CI 1.03; 1.84] and ≥20 cigarettes/day OR = 2.11[95% CI 1.31; 3.40]. Smoking by the partner was associated with decreased offspring happiness after adjustment for confounders, but did no show association with offspring depression. Offspring were less likely to be happy and more likely to be depressed if their mother smoked during pregnancy, and less likely to be happy if their father smoked during mother's pregnancy. Although we can not affirm that this is a "causal pathway", public policies to reduce smoking in pregnancy could improve the health of the offspring in the short and long term.

    ABSTRACT: OBJECTIVE: The present study investigated the consumption frequency of various meats according to sociodemographic and nutritional variables and analyzed the consumption of high-fat diets according to type of meat by southern Brazilian adolescents. METHODS: This cross-sectional study included the 1993 birth cohort from Pelotas (RS). The consumption frequency of red, white and organ meats and sausage were investigated by a food frequency questionnaire adapted for this study. Dietary fat content was determined as proposed by Block. The independent variables were gender, skin color, socioeconomic level, maternal education level and nutritional status. The statistical analyses included the Chi-square linear tendency test and the Chi-square test of homogeneity. RESULTS: A total of 4,325 adolescents with a mean age of 14.7 years, SD=0.3 years, were assessed, of which 51.2% were females. Red meat was consumed more frequently daily than white meat (43.0% and 9.7%, respectively). Sausage consumption frequency greater than 4 times per week was reported by 48.5% of the sample, and 81.4% reported to consume organ meats rarely or never. Adolescents of higher socioeconomic levels and of mothers with higher education levels consumed more red meats and sausages, while those in the opposite situation consumed more white meats. Adolescents who consumed meats more frequently also consumed a high-fat diet. CONCLUSION: Red meats and sausages were the meats most frequently consumed by the study adolescents. However, adolescents of higher socioeconomic levels consumed red meats more often, while those of lower socioeconomic levels consumed white meats more often.

    ABSTRACT: Maternal nutrition interventions are efficacious in improving birth outcomes. It is important to demonstrate that if delivered in field conditions they produce improvements in health and nutrition. Analyses of scaling-up of five program implemented in several countries. These include micronutrient supplementation, food fortification, food supplements, nutrition education and counseling, and conditional cash transfers (as a platform for delivering interventions). Evidence on impact and cost-effectiveness is assessed, especially on achieving high, equitable, and sustained coverage, and reasons for success or failure Systematic review of articles on large-scale programs in several databases. Two separate reviewers carried out independent searches. A separate review of the gray literature was carried out including websites of the most important organizations leading with these programs. With Google Scholar a detailed review of the 100 most frequently cited references on each of the five above topics was conducted. Food fortification programs: iron and folic acid fortification were less successful than salt iodization initiatives, as the latter attracted more advocacy. Micronutrient supplementation programs: Nicaragua and Nepal achieved good coverage. Key elements of success are antenatal care coverage, ensuring availability of tablets, and improving compliance. Integrated nutrition programs in India, Bangladesh, and Madagascar with food supplementation and/or behavioral change interventions report improved coverage and behaviors, but achievements are below targets. The Mexican conditional cash transfer program provides a good example of use of this platform to deliver maternal nutritional interventions. Programs differ in complexity, and key elements for success vary with the type of program and the context in which they operate. Special attention must be given to equity, as even with improved overall coverage and impact inequalities may even be increased. Finally, much greater investments are needed in independent monitoring and evaluation.

    ABSTRACT: O objetivo do estudo foi avaliar a efetividade de um programa educacional sobre tabagismo desenvolvido pelo Instituto Nacional do Câncer em adolescentes escolares de Pelotas, RS. Das 46 escolas públicas da cidade, 32 foram sorteadas aleatoriamente e, posteriormente, randomizadas em grupo controle ou intervenção. Em ambas as fases do estudo (pré e pós-intervenção), os estudantes de 7ª e 8ª série responderam a um questionário, e uma amostra de urina foi coletada para análise de cotinina. A intervenção educativa teve duração de seis meses. Os desfechos estudados foram: "auto-relato de uso de cigarros nos últimos 30 dias" e "concentração de cotinina na urina (categorizada em > 10 ng/ml e > 30 ng/ml)". A intervenção não provocou mudança na prevalência de tabagismo, tanto mensurado por auto-relato como pela concentração de cotinina. No entanto, o conhecimento dos alunos acerca dos malefícios do cigarro aumentou no grupo intervenção. Em resumo, não houve efetividade da intervenção educacional para mudanças de comportamento, mas houve melhora no conhecimento dos prejuízos do fumo.

    ABSTRACT: The study aims to describe and compare two methods of energy intake assessment and one measure of energy expenditure applied in adolescents from a birth cohort. In a sub-sample of the 1993 Pelotas (Brazil) birth cohort, followed up in 2006-7, information on intake was obtained through a food-frequency questionnaire (FFQ) and three 24-hour-recalls (24hR), while energy expenditure was assessed using an accelerometer. Bland & Altman plots were used in the analyses in order to compare the methods. The mean difference between FFQ and 24hR was 592 ± 929cal/day. Compared to energy expenditure, intake was overestimated when measured by FFQ (357 ± 968cal/day) and underestimated by 24hR (-278 ± 714cal/day). In spite of the great differences between energy intake obtained using the two methods, lower differences were observed when these methods were compared to expenditure.

    ABSTRACT: The present study sought to assess the impact of an intervention to reduce weight and control risk factors of noncommunicable chronic diseases in overweight or obese adults who are users of primary and secondary healthcare units of the public health system of Pelotas, Brazil. We hypothesized that individuals who received an educational intervention regarding how to lose weight and prevent other noncommunicable chronic disease risk factors through nutrition would lose weight and acquire active habits during leisure time more frequently than individuals under regular care. Two hundred forty-one participants from the Nutrition Outpatient Clinic of the Medical Teaching Hospital of the Federal University of Pelotas, Brazil, aged 20 years or older and classified as overweight or obese were randomly allocated to either the intervention group (IG; n = 120) or control group (CG; n = 121). The IG received individualized nutritional care for 6 months, and the CG received individualized usual care of the health services. Intention-to-treat analyses showed that at 6 months, mean fasting glycemia and daily consumption of sweet foods and sodium were reduced, and the time spent on physical leisure activity was increased in IG. Analysis of adherence to the protocol of the study revealed that individuals from IG had lost more in body weight, waist circumference, and fasting glucose compared to the CG. Leisure time physical activity increased in IG. Individuals adhered equally to the dietetic recommendations, irrespective of the nutrition approach that was used.

    ABSTRACT: To estimate the prevalence of traumatic injury in primary dentition among children aged 12-71 months old, as well as to evaluate the distribution of traumatic injuries, type of trauma and associated factors. After the research project approval by the Ethics Research Committee, a cross-sectional study was carried out including 571 preschool children--both from public and private schools--in the city of Pelotas, Southern Brazil. Data were collected by means of anterior teeth examination, and by the administration of a structured questionnaire to parents. The classification proposed by Andreasen & Andreasen was used, and crown discoloration and fistula were added to this criterion. The prevalence of dental trauma was 36.6% (95% CI 32.7-40.5), with no significant differences between boys and girls. Trauma were more frequent among older children (P = 0.001). No associations were found for maternal schooling, income and type of school. The most frequent trauma was enamel fracture, and the most affected tooth was number 61. A significant statistical association was observed between the presence of dental trauma during clinical examination and parental report of trauma occurrence. The percentage of parents who looked for dental treatment was higher among children from private schools (P = 0.001). The most frequent place of occurrence was home, and the most frequently reported etiology was child's own-height fall. Dental trauma in primary teeth is characterized as an accident that occurs due to the children's development stage, even when they are cared for by mothers of higher schooling and income. Parents should search for assistance right after trauma occurrence to minimize sequelae.

    ABSTRACT: Phase angle (PA), determined by bioelectrical impedance analysis (BIA), has been considered as a prognostic factor in several clinical conditions. The purpose of this study is to investigate PA, after adjusting for sex and age (standardized phase angle; SPA) as a prognostic factor for survival in cancer patients. A prospective study was conducted in 195 patients before the first chemotherapy course. BIA was performed in all patients and SPA was calculated. The Kaplan-Meier method was used to calculate survival. The Cox regression method was used to evaluate the independent prognostic effect of PA after adjustment for other variables. Patients with SPA < -1.65 had a smaller survival rate than those with SPA ≥ -1.65 (p < 0.001). Using Cox regression, the mortality rate was higher in patients with SPA < -1.65 (RR 3.12 CI: 2.03-4.79; p < 0.001). After multivariate analysis, patients with PA < -1.65 still presented a higher mortality rate (RR 2.35 CI: 1.41-3.90; p = 0.001). The present study demonstrates that PA, used as SPA, is an independent prognostic indicator in this group of cancer patients receiving chemotherapy treatment even after adjustment for other prognostic variables.
