Objective: To verify the prevalence of sleep quality and duration and its association with the level of physical activity, screen time and nutritional status in adolescents. Methods: This is a cross-sectional study with 1,432 adolescents (53.1%, female), ten to 14 years old (12.0±1.0 year) from public schools in Joao Pessoa, Northeast Brazil. Physical activity (≥300 vs. 2 h/day) and duration (

The scope of this article is to analyze the relationship between insufficient sleep duration, overweight/obesity and the consumption of ultra-processed foods among adolescents aged 10 to 14 years. This is a cross-sectional study, with an evaluation of 1,384 adolescents from public schools in João Pessoa-PB, participating in the Longitudinal Study on Sedentary Behavior, Physical Activity, Diet and Adolescent Health (LONCAAFS). Sociodemographic variables, sleep duration, class shift, anthropometric nutritional status, sedentary behavior and food consumption were measured. Linear and logistic regression of the following were performed using Stata 13.0 Software: the prevalence of short sleep duration of 29.5% (9h/night); a significant association between short sleep duration and excess weight only for adolescents12 years old. With respect to the relationship between sleep duration and the consumption of ultra-processed foods, the longer the sleep duration, the lower the consumption of snacks by adolescents under 12 years old, with a positive association for ≥12 years old only with adjustment by the physical activity variable. There was no association with the "sugary drinks" and "cookies" groups for any of the age groups analyzed.O objetivo deste artigo é analisar a relação entre duração insuficiente do sono, sobrepeso/obesidade e o consumo de alimentos ultraprocessados em adolescentes de 10 a 14 anos.

Associação significativa entre a curta duração do sono e o excesso de peso somente para adolescentes12 anos. Quanto à relação entre a duração do sono e o consumo de alimentos ultraprocessados, quanto maior a duração do sono, menor o consumo de lanches pelos adolescentes menores de 12 anos, com associação positiva para ≥12 anos apenas com ajuste pela variável atividade física. Não houve associação com os grupos “bebidas açucaradas” e “biscoitos” para nenhuma das faixas etárias analisadas.

Objective: To evaluate the pre-gestational and current nutritional status of pregnant women and its intercurrences that influence on the maternal health. Material and Methods: This cross-sectional study had a convenience sample composed by 36 pregnant women. The data collection instrument was a questionnaire containing open questions and dichotomous and multiple-choice closed questions. Information referring to age, nutritional status, pre-gestational and gestational weight, existing pathologies and obstetric outcome was collected. Data were analyzed using the SPSS software and presented by descriptive statistics. Results: The age of the pregnant women ranged from 14 to 39 years and it was observed that 11.1% of the women presented malnutrition in the pre-gestational period and this percentage increased to 27.7% during pregnancy. Overweight increased from 22.2% in the pre-gestational period to 33.3% during pregnancy. The mean pre-gestational weight was 58.8 kg (±6.77 kg) while the mean gestational weight was 68.0 kg (±12.2 kg). The mean weight gain in the patients who had vaginal delivery was 9.2 kg, while in those who had cesarean section delivery the mean weight gain was 12.2 kg. Conclusion: It was observed an increase in malnutrition and overweight during pregnancy, demonstrating the importance of having a healthy diet and a maintaining an adequate weight gain during pregnancy in order to preserve mother-child health. DESCRIPTORS: Pregnant Women. Nutritional Status. Weight Gain. Obesity.
