Vitamin D is associated with the hypertriglyceridemic waist phenotype in Brazilian children.

BACKGROUND: Prevalence of cardiometabolic risk factors is increasing and vitamin D insufficiency/deficiency has become a worldwide public health problem, even in tropical countries. Therefore, we identified the prevalence of hypertriglyceridemic waist phenotype (HWP) and evaluate its relationship with vitamin D insufficiency/deficiency. METHODS: A cross-sectional study with 378 children aged 8 and 9 enrolled in all urban schools in the city of Viçosa, MG, Brazil. Anthropometric measurements, body composition (dual energy X-ray absorptiometry), biochemical tests and clinical evaluation were performed. Poisson regression was used to analyze the association between vitamin D and HWP. RESULTS: Prevalence of HWP was 16.4%. This prevalence was higher among children with vitamin D insufficiency and deficiency and in those with a greater number of other cardiometabolic risk factors. Multiple regression analysis showed that children with vitamin D insufficiency and deficiency had, respectively, prevalence 85% (95% CI: 1.03-3.30) and 121% (95% CI: 1.11-4.45) higher of HWP than the vitamin D sufficiency group. CONCLUSION: Vitamin D insuffiency and deficiency were associated with a higher prevalence of HWP among children, regardless of the presence of other cardiometabolic risk factors, indicating an additional risk of inadequate vitamin D status to cardiometabolic health in childhood.

Consumo de carotenoides e polifenóis em indivíduos com risco cardiometabólico / Carotenoid and polyphenol consumption in subjects with cardiometabolic risk

Introdução: Os compostos bioativos possuem um importante papel antioxidante e proporcionam um tratamento adjuvante no combate às Doenças Crônicas Não Transmissíveis. Objetivo: Determinar o consumo atual de compostos bioativos (carotenoides e polifenóis) em indivíduos com risco cardiometabólico. Metodologia: Estudo transversal com 227 sujeitos participantes do Programa de Atenção à Saúde Cardiovascular da Universidade Federal de Viçosa. Foram coletados dados de ingestão alimentar atual para determinação do consumo de carotenoides, polifenóis, micro e macronutrientes utilizando um recordatório 24 horas. Dados antropométricos, de composição corporal, sociodemográficos e de estilo de vida também foram avaliados. O teste de Mann Whitney e correlação de Spearman foram realizados no SPSS v.20.0, com significância de p2,52 mg/dia) obtiveram menores valores de gordura corporal total (p<0,001). Conclusão: Nossos resultados indicam que um maior consumo de quempferol esteve relacionado com menores valores de indicadores de adiposidade total. Porém, mais estudos são necessários para se estabelecer os mecanismos envolvidos em seus potenciais benefícios em relação à adiposidade e resposta metabólica (AU)

Introduction: The bioactive compounds play an important antioxidant role and provide an adjuvant treatment to fight Chronic Noncommunicable Diseases. Objective: To determine the current intake of bioactive compounds (carotenoids and polyphenols) in subjects with cardiometabolic risk. Methods: Cross-sectional study of 227 subjects who participated in the Cardiovascular Health Care Program of the Federal University of Viçosa. Data of current dietary intake were collected for the determination of carotenoids, polyphenols, micronutrients and macronutrients consumption using a 24-hour recall. Data of anthropometry, body composition, sociodemographic conditions and lifestyle were also evaluated. The Mann Whitney test and Spearman correlation were performed using SPSS v.20.0, with significance of p 2.52 mg / day) had lower values of total body fat (p< 0.001). Conclusion: Our results indicate that a higher intake of kaempferol was associated with lower values of total adiposity indicators. However, more studies are necessary to establish the mechanisms involved in their potential benefits regarding adiposity and metabolic response (AU)
