Artigo originAl RESUMOAdequados hábitos alimentares e a prática de exercícios físicos exercem efeito benéfico sobre as dislipidemias. Se associados, podem ainda otimizar as mudanças do perfil lipoprotéico plasmático, sendo, além disso, intervenções de custo moderado quando comparados com tratamentos medicamentosos e dependentes de alta tecnologia. Este estudo tem por objetivo avaliar o impacto do exercício físico isolado e combinado com dieta sobre o perfil lipídico em indivíduos com sobrepeso/obesos. O presente trabalho é do tipo retrospectivo analítico observacional. Nele foi analisada a evolução do perfil lipídico e do peso, por período entre três e seis meses, de 30 indivíduos, divididos em dois grupos: grupo exercício (prática de exercício físico) e grupo dieta (prática de exercício físico associada à intervenção nutricional). Foram encontradas reduções estatisticamente significativas no CT (-14,4mg/dl; P = 0,022) e no LDL-c (-20,9mg/dl; P = 0,013) para os componentes do grupo exercício. Tal redução também ocorreu em relação à razão CT/ HDL-c (-0,9; P = 0,005) para os componentes do grupo dieta. Foi observada elevação dos níveis de HDL-c, apenas no grupo dieta (+4,2 mg/dl). Nesse mesmo grupo verificou-se diminuição no CT (-8mg/dl) e no LDL-c (-9,8mg/dl), bem como redução de peso (-2,6kg), no entanto, tais resultados não foram estatisticamente significativos. Quanto aos níveis de TG, não foi verificada evolução positiva em ambos os grupos. Concluiu-se que o efeito isolado do exercício físico foi mais evidente em relação às variáveis CT e LDL-c. Os TG não sofreram modificações positivas com a prática exclusiva de exercícios físicos ou com sua associação à dieta. Para as variáveis HDL-c e peso, a combinação da dieta com o exercício físico apresentou maiores benefícios.Palavras-chave: nutrição, atividade física, dislipidemia, obesidade, doenças cardiovasculares. ABSTRACTAdequate eating habits and physical exercise have a beneficial effect on dislipidemies. When associated, they might even optimize changes to the plasmatic lipoproteic profile, apart of which they are moderatecost interventions if compared to drug-based and high-tech depending treatments. The present study aims at assessing the impact of physical exercise as isolated and combined with a diet on the lipidic profile of overweight/obese individuals. Tn observational analytical retrospective study has looked into the evolution of the lipidic profile and weight over a period of 3 to 6 months of 30 individuals divided in two groups: the exercise group (physical exercise practice) and the diet group (physical exercise associated with a nutritional intervention). Significant statistical reductions were found in the CT (-14.4 mg/dl; P=0,022) and in the LDL-c (-20.9 mg/dl; P = 0,013) for the components in the exercise group. Such reduction has also occurred regarding the CT/HDL-c (-0,9; P = 0,005) ratio for the components of the diet group. The increase in the HDL-c levels was observed only in the diet group (+4.2 mg/dl). In this same group a decrease in t...
The aim of this study was to evaluate the impact of the Dietary Approaches to Stop Hypertension (DASH) diet on glycaemic control and consumption of processed (PF) and ultraprocessed (UPF) foods in pregnant women with pre-gestational diabetes mellitus (PGDM). This is a randomised, controlled, single-blind clinical trial with forty-nine adult women with PGDM, followed at a public maternity hospital in Rio de Janeiro, Brazil. The control group (CG) received a standard diet consisting of 45–55 % of the total energy intake of carbohydrates, 15–20 % of proteins and 25–30 % of lipids. The DASH group (DG) received an adapted DASH diet, which did not differ from the standard diet in the percentage of macronutrients, but had higher contents of fibre, unsaturated fats and minerals such as Ca, Mg and K; and lower contents of Na and saturated fats than the standard diet. In the analysis by protocol, the DG presented a higher incidence of glycaemic control after 12 weeks of intervention (57·1 v. 8·3 %, P = 0·01, moderate effect size) and a lower mean consumption of UPF (−9·9 %, P = 0·01) compared with the CG. There was no statistically significant difference in fasting and postprandial blood glucose concentrations, or in the consumption of PF between the groups (P > 0·05). The DASH diet may be a strategy for glycaemic control in pregnant women with PGDM, favouring the adoption of a nutritionally adequate diet with lower consumption of UPF. Further studies are needed to investigate the effect of the DASH diet on glycaemic profile, and maternal and perinatal outcomes in women with PGDM.
RESUMOObjetivo: Descrever procedimentos metodológicos para elaboração de plano alimentar para gestantes com Diabetes Mellitus (DM) com base na Dietary Approaches to Stop Hypertension (dieta DASH). Métodos: Estudo metodológico. Etapas: revisão da literatura; tradução e adaptação da DASH original; elaboração do plano alimentar DASH adaptado, boletim de orientação nutricional, listas de substituições e materiais educativos; discussão com especialistas; comparação dos custos dos cardápios, e discussão com gestantes. Resultados: Adaptação: foram incluídos alimentos brasileiros, fontes dos nutrientes da DASH e consumidos com frequência pela população. Foram elaborados boletim de orientação nutricional, listas de substituições e, para a pesquisa de custos, cardápios, com valor energético total (VET) médio de 2300 kcal, listas de equivalentes com VETs de 2000 a 2800 kcal e materiais educativos. Foram realizadas discussões com especialistas e com gestantes com DM prévio. O custo das dietas foi distinto (R$ 19,55: DASH x R$ 16,50: tradicional), mas não foi considerado significativo por especialistas e gestantes. Conclusão: A adaptação da dieta DASH original resultou na primeira versão em português adaptada à cultura brasileira e aos hábitos alimentares de gestantes com DM prévio. Este plano alimentar poderá contribuir para a prevenção de complicações gestacionais como as Síndromes Hipertensivas da Gravidez.
Objective To evaluate the effect of the carbohydrate counting method (CCM) on glycemic control, maternal, and perinatal outcomes of pregnant women with pregestational diabetes mellitus (DM). Methods Nonrandomized controlled clinical trial performed with 89 pregnant women who had pregestational DM and received prenatal care in a public hospital in Rio de Janeiro, state of Rio de Janeiro, Brazil, between 2009 and 2014, subdivided into historic control group and intervention group, not simultaneous. The intervention group (n = 51) received nutritional guidance from the carbohydrate counting method (CCM), and the historical control group (n = 38), was guided by the traditional method (TM). The Mann-Whitney test or the Wilcoxon test were used to compare intra- and intergroup outcomes and analysis of variance (ANOVA) for repeated measures, corrected by the Bonferroni post-hoc test, was used to assess postprandial blood glucose. Results Only the CCM group showed a reduction in fasting blood glucose. Postprandial blood glucose decreased in the 2nd (p = 0.00) and 3rd (p = 0.00) gestational trimester in the CCM group, while in the TM group the reduction occurred only in the 2nd trimester (p = 0.015). For perinatal outcomes and hypertensive disorders of pregnancy, there were no differences between groups. Cesarean delivery was performed in 82% of the pregnant women and was associated with hypertensive disorders (gestational hypertension or pre-eclampsia; p = 0.047). Conclusion Both methods of nutritional guidance contributed to the reduction of postprandial glycemia of women and no differences were observed for maternal and perinatal outcomes. However, CCM had a better effect on postprandial glycemia and only this method contributed to reducing fasting blood glucose throughout the intervention.
