- Eating meals with parents is associated with better quality of diet for Brazilian adolescents(2019) MARTINS, Bianca Garcia; RICARDO, Camila Zancheta; MACHADO, Priscila Pereira; RAUBER, Fernanda; AZEREDO, Catarina Machado; LEVY, Renata BertazziThe objective was to investigate how often Brazilian adolescents eat meals with their parents and verify the association between this habit and quality of the diet. Data were from the Brazilian National Survey of School Health (PeNSE 2015). The sample consisted of adolescents enrolled in the ninth grade in public and private schools, ranging in age from 11 to 19 years. The target exposure was eating meals with parents (0-4 and >= 5 days/ week) and the outcomes were frequent consumption (>= 5 days/week) of healthy and unhealthy dietary markers. Healthy diet scores (range 0-21) and unhealthy diet scores (range 0-35) were based on total days that the adolescent reported consuming each of the dietary markers. Poisson and linear regression models were used, adjusted by sociodemographic variables. Frequent sharing of meals with parents (>= 5 days/week) was seen in 74% (9.5%CI: 73.4-74.7) of the adolescents. Those reporting this habit showed higher likelihood of frequent consumption of beans (PR = 1.22; 9.5%CI: 1.19-1.26), fruits (PR = 1.34; 9.5%CI: 1.28- 1.39), and vegetables (PR = 1.39; 9.5%CI: 1.34-1.44), and lower likelihood of frequent consumption of sweets (PR = 0.91; 95%CI: 0.88-0.94), ultra-processed salty foods (PR = 0.91; 95%CI: 0.87-0.94), and fried salty snacks (PR = 0.85; 95%CI: 0.80-0.90). Eating meals with parents was positively associated with healthy diet scores and inversely associated with unhealthy diet scores . Eating meals with parents is a common habit in Brazilian adolescents and is associated with better quality of diet.
- School meals consumption is associated with a better diet quality of Brazilian adolescents: results from the PeNSE 2015 survey(2021) BOKLIS-BERER, Mirena; RAUBER, Fernanda; AZEREDO, Catarina Machado; LEVY, Renata Bertazzi; LOUZADA, Maria Laura da CostaObjective: To assess the association between the consumption of school meals offered by the National School Feeding Program (PNAE, in the Portuguese acronym) and the diet quality of adolescents aged 11 to 19 years from Brazilian public schools. Design: Cross-sectional. Setting: Public schools in Brazil. Participants: A sample of 12 260 adolescents aged 11 to 19 years from 2015 National School Health Survey. High consumption of PNAE school meals were considered when the adolescents consumed school meals 5 d/week. Food consumption data were obtained from a 7-d FFQ and converted into three diet quality assessment scores, namely (1) consumption of healthy foods; (2) consumption of unhealthy foods and (3) overall diet quality. Crude and adjusted linear regression models were used to test the association between high consumption to school meals (daily consumption) and each diet quality score. Results: More than one-fifth of the adolescents (21 center dot 5 %) reported high consumption of school meals. High consumption of school meals was directly associated with the score of the overall diet quality (adjusted coefficient = 0 center dot 18; 95 % CI 0 center dot 07, 0 center dot 30) and healthy food consumption (adjusted coefficient = 0 center dot 42; 95 % CI 0 center dot 26, 0 center dot 57), and inversely associated with the unhealthy food consumption score (adjusted coefficient = -0 center dot 23; 95 % CI -0 center dot 35, -0 center dot 10). Conclusion: Our results showed that the consumption of PNAE meals may contribute to healthy eating promotion in Brazil.
- Plasma omega-3 fatty acids are positively associated with appendicular muscle mass index only in adults with low protein intake: Results from NHANES 2011-2012(2023) BRANCO, Flavia M. S. De; RINALDI, Ana Elisa M.; PEREIRA, Jaqueline L.; ROSCHEL, Hamilton; AZEREDO, Catarina M.; OLIVEIRA, Erick P. DeBackground: Omega-3 (6)-3) fatty acids may indirectly increase muscle protein synthesis making the muscle more sensitive to amino acids uptake; therefore, 6)-3 could promote benefits on muscle mass mainly when protein intake is low. However, no study has evaluated the association between 6)-3 fatty acids and muscle mass according to protein intake. Aim: To evaluate the association between plasma 6)-3 fatty acids and appendicular muscle mass index (AMMI) in adults according to the protein intake. Methods: A cross-sectional study was performed evaluating 1037 individuals aged 20-59 years from a sub -sample of the National Health and Nutrition Examination Survey (NHANES) 2011-2012. Gas chromatography-mass spectrometry method was used to assess plasma 6)-3 fatty acids. The lean mass was evaluated by dual-energy x-ray absorptiometry (DXA) and AMMI (kg/m2) was calculated by appendicular lean mass (kg) divided by height squared. The evaluation of protein intake was performed using two 24-h dietary recalls. Linear regression analysis was performed to assess the association of total plasma 6)-3, docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), alpha-linolenic acid (ALA), and EPA plus DHA with AMMI according to protein intake (<0.8; >= 0.8; >= 0.8 -<1.2; >= 1.2 -<1.6; and >= 1.6 g/kg/d). Results: Total plasma 6)-3 (0 = 0.0030; CI = 0.0013-0.0046; p = 0.002), ALA (0 = 0.0063; CI = 0.0020 -0.0107; p = 0.008), EPA (0 = 0.0073; CI = 0.0005-0.0142, p = 0.037), DHA (0 = 0.0057; CI = 0.0022 -0.0093; p = 0.004) and EPA + DHA (0 = 0.0040; CI = 0.0010-0.0071; p = 0.013) were positively associated with AMMI in individuals with low protein intake (<0.8 g/kg). However, no association was observed in individuals with protein intake higher than 0.8 g/kg. Conclusion: Plasma 6)-3 fatty acids were positively associated with AMMI only in individuals with low protein intake.
- Individual and contextual factors associated with verbal bullying among Brazilian adolescents(2015) AZEREDO, Catarina Machado; LEVY, Renata Bertazzi; ARAYA, Ricardo; MENEZES, Paulo RossiBackground: Few studies have been carried out in low-middle-income countries assessing contextual characteristics associated with bullying. This study aimed to assess the relative importance of contextual (school and city) and individual-level factors to explain the variance in verbal bullying among a nationally representative sample of Brazilian adolescents. Methods: 59,348 students from 1,453 schools and 26 state capitals and the Federal District participated in the National Survey of School Health among 9th Grade Students (PeNSE, 2009). We performed multilevel logistic regression in a three level model (individual, school and city). Results: The 30-day prevalence of verbal bullying among these students was 14.2%. We found that 1.8% and 0.3% of the total variance in bullying occurred at school-level and city-level, respectively, and 97.9% at individual-level. At city-level, all factors included failed to demonstrate a significant association with bullying (p <0.05) whereas at school-level, private schools presented more bullying than public schools (OR = 1.17, CI 1.04-1.31). At individual-level, male gender, younger age, not living with both parents, exposed to domestic violence, under or overweight were all associated with bullying. Conclusions: All socioeconomic indicators assessed contributed little to explain the variance in bullying at individual, school or city-level. Population subgroups at risk identified according to their individual profile could be targeted in future interventions in Brazil.
- The Role of School Environment in Physical Activity among Brazilian Adolescents(2015) REZENDE, Leandro Fornias Machado de; AZEREDO, Catarina Machado; SILVA, Kelly Samara; CLARO, Rafael Moreira; FRANCA-JUNIOR, Ivan; PERES, Maria Fernanda Tourinho; LUIZ, Olinda do Carmo; LEVY, Renata Bertazzi; ELUF-NETO, JoseObjective To analyze the association of physical activity facilities and extracurricular sports activities in schools with physical activity among adolescents. Methodology/Principal Findings We used data collected for the National Survey of School Health in 2012. The national representative sample comprised 109,104 Brazilian students from 2,842 schools. We calculated the prevalence of participation in physical education classes, leisure-time physical activity, and total physical activity level. We also evaluated the following physical activity facilities: sports courts, running/athletics tracks, schoolyard with teacher-directed physical activities, swimming pools, locker rooms; and the offer of extracurricular sports activities. Schools with at least one physical activity facility had increased odds of participation in physical education (OR 1.59; 95% CI 1.20 to 2.10). However, in order to increase leisure-time physical activity (OR 1.14; 95% CI 1.03 to 1.26) and total physical activity level (OR 1.15; 95% CI 1.06 to 1.24) at least four and two facilities, respectively, were necessary. Extracurricular sports activities in schools were positively associated with leisure-time physical activity and physical activity level. The number of sports courts and swimming pool in a school were associated with participation in physical education classes. Availability of sports courts, running/athletics tracks, and swimming pool in schools were associated with leisure-time physical activity. Total physical activity was associated with schools with sports courts, schoolyard with teacher-directed physical activities, and swimming pool. Conclusions School-level characteristics have important potential to increase the possibility of engagement in physical activity in and out of school, and therefore have a fundamental role in promoting these practices.
