This is a cross-sectional school-based study that evaluated the prevalence and associated factors of the daily intake of fruit and vegetables by adolescents at public schools in Caruaru, Pernambuco. Poisson regression with a hierarchical model, including sociodemographic variables in the first hierarchical level, behavioral variables in the second and diet-related variables in the third was used to assess the factors associated with fruit and vegetable intake. The results showed that of the 600 adolescents interviewed, 10% reported never eating fruit and 30.7% mentioned not eating vegetables. Prevalence of fruit intake was 32.9% and vegetables 29.0%. Only 6.5% reported eating both kinds of food daily. Merely the daily vegetable intake showed a significant difference according to sex (higher among girls). Daily fruit intake was 63% higher among adolescents living in urban areas. Not consuming alcohol was associated with higher fruit intake, though not to vegetable intake. Daily intake of fruits and vegetables was 2.4 times higher among adolescents who consumed rice and beans daily. Daily fruit and vegetable intake among adolescents in Caruaru is below the recommendations, and was associated with gender, residence area, consumption of alcoholic beverages and consumption of rice and beans.

This population-based study evaluated the use of diet sweeteners by adults (> 20 years) in Pelotas, Rio Grande do Sul State, Brazil. Data were collected from January to July 2010 (n = 2,732). Besides specific questions on diet sweeteners, demographic, socioeconomic, and health characteristics were recorded. Heterogeneity and linear trend chi-square tests were used for the statistical analysis. Prevalence of sweetener use was 19% (95%CI: 1.1-20.9), and was 3.7 times higher in elderly individuals as compared to 20-29-year-olds. Economic level and nutritional status were significantly associated with sweetener use. Nearly 98% of the sample used liquid sweeteners; the most frequently consumed (89.2%) were those containing saccharin or sodium cyclamate. Average intake was 10 drops of liquid sweetener or 1.5 sachets of powdered sweetener. Use of diet sweeteners was higher among women and the elderly.

OBJETIVO: Descrever a frequencia de consumo de diferentes tipos de carnes conforme variaveis sociodemograficas e nutricionais, e analisar o consumo, em adolescentes do Sul do Brasil, de dieta rica em gordura conforme os tipos de carne consumidos. METODOS: Estudo transversal realizado com adolescentes pertencentes a coorte de nascimentos de 1993, em Pelotas (RS). A frequencia de consumo de carnes vermelhas, brancas, visceras e embutidos foi avaliada por um Questionario de Frequencia de Consumo Alimentar, adaptado para este estudo. A ingestao de dieta rica em gordura foi avaliada a partir do instrumento proposto por Block. As variaveis independentes foram sexo, cor da pele, nivel socioeconomico, escolaridade materna e estado nutricional. Nas analises estatisticas, foram utilizados testes Qui-quadrado de heterogeneidade e de tendencia linear. RESULTADOS: Foram avaliados 4.325 adolescentes com idade media de 14,7, DP=0,3 anos, dos quais 51,2% eram do sexo feminino. A frequencia de consumo diario de carnes vermelhas foi maior do que a de carnes brancas (43,0% e 9,7%, respectivamente). O consumo de embutidos por mais do que quatro vezes por semana foi referido por 48,5% dos individuos, e 81,4% relataram consumir visceras raramente ou nunca. Adolescentes de maior nivel socioeconomico e filhos de maes com maior escolaridade apresentaram maior consumo de carnes vermelhas e embutidos, enquanto aqueles em situacao oposta apresentaram maior consumo de carnes brancas. Adolescentes que consomem carnes com maior frequencia tambem consomem dieta rica em gordura. CONCLUSAO: As carnes consumidas com maior frequencia pelos adolescentes foram as vermelhas e os embutidos. No entanto, adolescentes de maior nivel socioeconomico consomem carnes vermelhas com maior frequencia, enquanto adolescentes menos favorecidos economicamente consomem mais carnes brancas.

A school-based cross-sectional study in 2007 evaluated the prevalence and associated factors of daily consumption of soft drinks, sweets and fried foods among adolescents (15 to 20 years of age) in public schools in Caruaru in the state of Pernambuco. To evaluate the factors associated with the daily consumption of the above foods, a multivariate and hierarchical analysis was conducted using Poisson regression, with social and demographic variables at the first hierarchical level, behavioral variables at the second level and dietary standards at the third level. Consumption of soft drinks, sweets and fried foods at least once a week was declared by 90.9%, 95.4% and 89.6% of the adolescents, respectively. The corresponding prevalence of the daily consumption of these items was 30.2%, 42% and 28.3%. The daily consumption of sweets was 21% higher among girls and 25% higher among adolescents who ate rice and beans daily. With respect to fried foods, girls mentioned 37% greater consumption than boys. Adolescents who consumed meat every day admitted a 43% higher daily consumption of fried foods. The consumption of soft drinks, sweets and fried foods among the adolescents from Caruaru was high and showed a homogeneous consumption standard for most variables analyzed.

The aim of this study was to describe fat (FM) and lean body mass (LBM) in six-year-old children from the 2004 Pelotas Birth Cohort, stratified by gender. Dual-Energy X-ray Absorptiometry was used to measure FM and LBM, FM and LBM indexes, and percentage (%) of FM and LBM. Mean measures of adiposity were higher among girls (6.3 kg, 4.2 kg/m(2) and 23.4% vs. 5 kg, 3.3 kg/m(2) and 18%) while LBM measures were higher among boys (19.3 kg, 13 kg/m(2) and 78.5% vs. 17.7 kg, 12.2 kg/m(2) and 73.2%). In both boys and girls mean measures of adiposity increased with socioeconomic status and maternal education. Mean measures of adiposity were higher among white-skinned children while %LBM was higher among black-skinned children. Preterm compared to full-term children showed lower mean measures of adiposity and LBM. Female sex, white skin color and higher socioeconomic conditions are associated with higher adiposity in childhood.

A cross-sectional population-based study was conducted in Pelotas, Rio Grande do Sul State, Brazil, to assess the prevalence of menstrual disorders and their distribution according to parity and demographic, social, and behavioral characteristics among 1,078 women aged 15-54 years. Menstrual disorders included heavy menstrual bleeding, inter-menstrual bleeding, short cycle, long cycle, and prolonged menses. Prevalence rates and 95% confidence intervals were calculated. Overall prevalence of menstrual disorders was 46.4% (43.3-49.4). The most prevalent disorder was heavy menstrual bleeding (23.2%; 20.5-25.8), followed by short cycle (19.2%; 16.6-21.8), long cycle (14.8%; 12.7-16.9), inter-menstrual bleeding (11.1%; 9.1-13.2), and prolonged menses (7.9%; 6.3-9.4). Menstrual disorders are frequent in the population and are associated with age 35 years or older, low schooling, high parity, tubal ligation, and smoking.
