- Food environments in schools and in the immediate vicinity are associated with unhealthy food consumption among Brazilian adolescents(2016) AZEREDO, Catarina Machado; REZENDE, Leandro Fornias Machado de; CANELLA, Daniela Silva; CLARO, Rafael Moreira; PERES, Maria Fernanda Tourinho; LUIZ, Olinda do Carmo; FRANCA-JUNIOR, Ivan; KINRA, Sanjay; HAWKESWORTH, Sophie; LEVY, Renata BertazziBackground. Evidence of the influence of the school food environment on adolescent diet is still little explored in low-and middle-income countries. We aimed to evaluate the association between food environment in schools and the immediate vicinity and the regular consumption of unhealthy food among adolescents. Methods. We used cross-sectional data collected by the Brazilian National Survey of School Health (PeNSE) from a representative sample of adolescents attending 9th grade public and private schools in Brazil, in 2012. We estimated students' regular consumption (>5 days/week) of unhealthy food (soft drinks, bagged salty snacks, deep fried salty snacks and sweets) and school availability, in the cafeteria or an alternative outlet, of the same food plus some healthy options (fruit and natural fruit juice). We performed multilevel logistic regression models. Results. Having a cafeteria inside school selling soft drinks (private schools OR = 1.23; 95% CI = 1.14-1.33; public schools OR = 1.13; 95% CI = 1.06-1.20) and deep fried salty snacks (private schools OR = 1.41 95% CI = 1.26-1.57; public schools OR = 1.16 95% CI = 1.08-1.24) was associated with a higher consumption of these unhealthy foods of among students. In private schools, cafeteria selling fruit and natural fruit juice was associated with lower student consumption of bagged salty snacks (OR = 0.86; 95% CI 0.77-0.96) and soft drinks (OR = 0.85; 95% CI = 0.76-0.94). In addition, eating meals from the Brazilian School Food Program in public schools was associated with a lower consumption of unhealthy foods. Conclusions. Foods available in the school food environment are associated with the consumption of unhealthy food among adolescents in Brazil.
- Coronary heart disease mortality, cardiovascular disease mortality and all-cause mortality attributable to dietary intake over 20 years in Brazil(2016) REZENDE, Leandro Fornias Machado de; AZEREDO, Catarina Machado; CANELLA, Daniela Silva; LUIZ, Olinda do Carmo; LEVY, Renata Bertazzi; ELUF-NETO, JoseBackground/objectives: In the last two decades, in Brazil, there has been a decreasing trend of consumption of in natura or minimally processed food, while intake of ultra-processed food has markedly increased. We estimated the contribution of dietary intake in trends from coronary heart disease mortality (CHDM), cardiovascular disease mortality (CVDM), and all-cause mortality (ACM) over 20 years in Brazil. Methods: We used a representative sample of Brazilian households located in metropolitan areas to estimate dietary intake in 1987/88 and 2008/09. For both periods, we estimated fractions of CHDM, CVDM, and ACM attributable to healthy (fruits and vegetables) and unhealthy food items (sugar-sweetened beverages, processed and red meat). We also estimated the number of prevented or postponed deaths attributable to these food items. Results: The fraction of CHDM attributable to all food items increased from 28.6% in 1987/88 to 38.7% in 2008/09. CVDM attributable to food items increased from 13.7% in 1974 to 19.3% in 2008/09. ACM attributable to all food items increased from 20.1% in 1987/88 to 27.3% in 2008/09. Without the decrease in healthy food item consumption, and the increase in unhealthy food items, 3195 deaths from coronary heart disease, 5340 from cardiovascular disease, and 16,970 from all causes could have been prevented or postponed. Conclusions: The burden of cardiovascular diseases and mortality attributable to dietary intake has increased over the last 20 years in Brazil. These findings suggest a need for a population prevention approach, focused on dietary intake to reduce the burden of disease.
- Adesão ao tratamento farmacológico de pacientes hipertensos entre participantes do Programa Remédio em Casa(2016) MANSOUR, Samir Nicola; MONTEIRO, Camila Nascimento; LUIZ, Olinda do CarmoAbstract OBJECTIVE: to analyze adherence to medication and associated among factors hypertensive individuals taking part in the Medicine at Home Programme. METHODS: this was a cross-sectional study using a questionnaire administered to patients with full access to medication participating in the São Paulo City Health Department's Medicine at Home Programme; treatment adherence was analyzed according to sociodemographic and behavioral characteristics using Poisson regression. RESULTS: 106 patients with arterial hypertension and with full access to medication were interviewed and 80.2% had high adherence; there were no significant differences (p>0.05) between adhering and non-adhering participants with regard to sociodemographic, behavioral or clinical characteristics. CONCLUSION: with adequate provision of health care and full access to medicine, sociodemographic, behavioral and clinical factors did not influence adherence to medicine indicating that health service organization and health policies play a fundamental role in controlling hypertension.
- Case study in prevention(2016) REZENDE, L. F. M. de; REY-LóPEZ, J. P.; LUIZ, O. do Carmo; ELUF-NETO, J.In this chapter, we highlight our specifi c experience in conducting and reporting an overview of systematic reviews about sedentary behavior and health outcomes. In this overview, we aimed to cover all types of sedentary behavior, health outcomes, and age groups, taking into account the methodological quality of the systematic reviews. We hope to contribute to the discussion of methodological aspects of overviews of systematic reviews for prevention and health, especially on emerging determinants of health, where there is little conceptual or methodological uniformity between studies. © Springer International Publishing Switzerland 2016.
