ABSTRACT Objective: The aim of the present study was to evaluate the prevalence of total cholesterol (TC) and low-density lipoprotein (LDL) alterations in children and adolescents in Brazil. Materials and methods: A systematic review and meta-analysis of prevalence. The search for articles was carried out in the databases: Medline (PubMed), Embase, Scientific Electronic Library Online (SciELO), Latin American and Caribbean Literature in Health Sciences (Lilacs). The meta-analysis was performed using the random effects model. The I² test was used to identify heterogeneity. Results: The present metanalysis revealed a significant prevalence of altered lipid profile in children and adolescents in Brazil. Regarding lipoprotein fractions, the prevalence of altered TC level was 27.47% (95% CI 24.36-30.82), and a smaller prevalence was observed for LDL cholesterol (19.29% – 95% CI 15.21-24.16). The models revealed high heterogeneity (I² = 99%; p < 0.01), however the precise source of it was not identified; although type of school, age group, year and the region of Brazil appeared to influence the estimations of altered lipid profiles. Conclusion: An important prevalence of lipid alterations was observed among Brazilian children and adolescents. Those results reinforce the importance of knowing the lipid profile of children and adolescents to perform early interventions for this public.

Resumo O objetivo é examinar sistematicamente as evidências científicas que associam fatores ambientais (meio ambiente, meio ambiente social, planejamento ambiental e distribuição espacial da população) com o excessivo ganho de peso gestacional. Trata-se de uma revisão sistemática e meta-análise realizada seguindo os passos recomendados pelo Preferred Reporting Items for Systematic Reviews and Meta-Analyzes. Os estudos de incluídos basearam-se nos seguintes critérios PECO: P-gestantes, E-fatores ambientais, O-ganho de peso gestacional. O procedimento de pesquisa foi conduzido nas bases de dados EMBASE, Web of Science, Cinahl, LILACS e MEDLINE (PubMed). A relação entre os fatores socioeconômicos da microrregião de residência e o ganho de peso gestacional foi evidenciada pela ligação entre a residência em bairros de alta pobreza e o ganho de peso gestacional inadequado. Este estudo revelou a maior prevalência de ganho de peso gestacional excessivo em gestantes que vivem em áreas urbanas. Fatores ambientais da área de residência das gestantes implicados no ganho de peso gestacional excessivo. As descobertas desse estudo podem, portanto, contribuir para o desenvolvimento de políticas públicas para evitar o ganho de peso gestacional inadequado.

Abstract The aim is, systematically examine the scientific evidences that associated environmental factors (environment, social environment, environmental planning and spatial population distribution) with the excessive gestational weight gain. A meta-analysis and systematic review carried out as per the Cochrane Handbook recommendations and following the steps recommended by the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes. The inclusion studies were done with the following PECO criteria: P-pregnant women, E-environmental factors, O-weight gain. The search procedure was conducted on the databases EMBASE, Web of Science, Cinahl, LILACS and MEDLINE (PubMed). The relationship between the socioeconomic factors of the micro-region of residence and gestational weight gain was evidenced by the linkage between residing in high-poverty neighborhoods and inadequate gestational weight gain. This study revealed the higher prevalence of excessive gestational weight gain in pregnant women those lives in urban areas. Environmental factors of the pregnant women’s residence area implicated in the excessive gestational weight gain. Our findings can therefore contribute to the development of public policies to prevent inadequate gestational weight gain.

OBJETIVO: Comparar nível de atividade física (NAF) e cuidados relacionados ao exercício físico (EF) em pacientes com diabetes mellitus (DM). MÉTODOS: Pacientes com DM ambulatoriais (adultos e usuários de insulina) foram avaliados conforme NAF (questionário internacional; atividades moderadas, intensas e caminhadas realizadas em uma semana típica), questionados sobre prática formal de EF, autocuidado e episódios de hipoglicemia relacionados ao EF e motivos para não praticá-lo. RESULTADOS: Foram avaliados 225 pacientes: 107 (47,6%) com diabetes mellitus tipo 2 (DM2) e 118 (52,4%) com diabetes mellitus tipo 1 (DM1), sendo maior o número de pacientes com DM2 classificados como pouco ativos [33 (30,7%) vs. 12 (10,3%)] e menor a proporção dos muito ativos [9 (8,7%) vs. 29 (25%)], quando comparados com pacientes com DM1. Não praticantes de EF (n = 140) o faziam por motivos diferentes: pacientes com DM2 por "desconforto", "restrição médica" e "não gostarem"; pacientes com DM1 por "falta de tempo", "preguiça" e "hipoglicemia". Apenas 85 pacientes praticavam EF regularmente, independente do NAF, e 38,8% realizavam autocuidados como alimentação, alongamento, monitoramento da glicemia capilar. Pacientes com DM2 [5 (14,3%)] relataram menos episódios de hipoglicemia relacionada ao EF do que aqueles com DM1 [17 (34%)]. CONCLUSÃO: Pacientes com DM2 possuem NAF e comportamento relacionado à prática de EF diferentes de pacientes com DM1.

OBJECTIVE: To compare physical activity level (PAL) and care related to exercise in patients with diabetes mellitus (DM). METHODS: DM outpatients (adult, insulin-user patients) were assessed for PAL (international questionnaire; moderate- and high-level activities, as well as walking, over a typical week) and questioned about formal exercise practice, self-care, and hypoglycemic episodes related to exercise or reasons for not exercising. RESULTS: Two hundred twenty five patients were assessed: 107 (47.6%) had type 2 diabetes mellitus (DM2) and 118 (52.4%) had type 1 diabetes mellitus (DM1), with a larger percentage of patients with DM2 being classified as poorly active [33 (30.7%) versus 12 (10.3%)] and a lower percentage being classified as highly active [9 (8.7%) versus 29 (25%)], compared with patients having DM1. Patients who do not exercise (n = 140) gave different reasons for not doing so: patients with DM2 claimed that they "felt uncomfortable", "presented medical restrictions", and "did not like it"; DM1 patients claimed that they "had no time to exercise", "were lazy", and "had hypoglycemic episodes". Only 85 patients exercised regularly, regardless of the PAL, and 38.8% performed self-care, such as eating, stretching, and capillary glucose monitoring. Patients with DM2 [5 (14.3%)] reported a lower number of hypoglycemic episodes related to exercise than those with DM1 [17 (34%)]. CONCLUSION: Patients with DM2 have different PAL and behavior related to exercise than those seen in DM1 patients.

A doença cardiovascular (DCV) é a principal causa de mortalidade em pacientes com diabetes melito (DM), sendo essencial a intervenção dietética no manejo dessa complicação. O objetivo deste manuscrito foi revisar as evidências científicas que fundamentam as recomendações dietéticas da American Diabetes Association (ADA) para prevenção e tratamento da DCV nos pacientes com DM. As diretrizes da ADA baseiam-se, em sua maioria, em estudos com pacientes com DCV, porém sem DM. Nos pacientes com DM, um aumento na ingestão de peixe e de fibras solúveis são as recomendações dietéticas com benefício comprovado. Embora o DM possa ser considerado um equivalente de DCV estabelecida, a adoção das recomendações dietéticas de pacientes sem DM e com DCV para todos pacientes com DM é questionável - em especial quando são consideradas as peculiaridades da DCV no DM. Ensaios clínicos aleatorizados em pacientes com DM deverão fundamentar melhor os benefícios das intervenções dietéticas sobre a DCV.

Cardiovascular disease (CVD) is the main cause of mortality among patients with diabetes mellitus (DM), and dietary intervention is an essential measure to prevent and treat this complication. The aim of this manuscript was to review scientific evidence that underlies the dietetic recommendations of the American Diabetes Association (ADA) for prevention and treatment of CVD in patients with DM. The ADA guidelines are mostly based on studies performed on patients with CVD and without DM. The evidence-based dietary recommendations for patients with DM are to increase the intake of fish and soluble fibers. Although DM has been considered as an equivalent of established CVD, the adoption of the same dietary recommendations for patients without DM and with CVD for all patients with DM is still questionable - especially considering the peculiarities of CVD in DM. Randomized clinical trials including patients with DM should provide further information regarding the benefits of these dietary interventions for CVD.
