SUMMARY:

Metabolic Syndrome (MS) is a group of risk factors associated with the development of cardiovascular diseases and diabetes, with high global and national prevalence. Among the causal factors, inadequate nutrient intake and vitamin D deficiency stand out. The COVID-19 pandemic has worsened these conditions by negatively impacting eating habits and sunlight exposure, with potentially prolonged effects. In light of this, this study aims to examine the association between vitamin D status and MS components in the Brazuca Natal Study and the Brazuca Natal Post-COVID-19 Study. Both studies have a population-based, cross-sectional design. The Brazuca Natal Study began data collection in 2019 but was interrupted in 2020 due to the COVID-19 pandemic. The Brazuca Natal Post-COVID-19 Study was initiated in 2023 and completed in 2024, involving adults and elderly individuals of both sexes living in Natal. Socioeconomic data, food consumption, anthropometric measurements, blood pressure, sunlight exposure, and nutritional biomarkers related to MS and vitamin D status were collected in three stages: face-to-face interviews, biological sample collection, and two dietary recalls.
We initially assessed the prevalence of inadequate dietary intake of micronutrients in the Brazuca Natal Study, stratified by age group and income, primarily focusing on vitamin D intake among the study population. The results indicated high prevalences of inadequacy (>50%) before the pandemic in the consumption of calcium, vitamins B6, D, and E in adults and elderly individuals of both sexes, as well as magnesium in elderly men, and selenium and thiamine in adult and elderly women. The highest prevalence of inadequacy (>80%) was observed for vitamins D and E in all groups, with vitamin D inadequacy exceeding 95% regardless of sex and age group. We found that the prevalence of inadequacy varied according to income level, depending on the specific micronutrient.
Next, we assessed vitamin D status in relation to MS components and sunlight exposure in both studies. The analysis showed a significant association between total and HDL cholesterol and vitamin D deficiency in the Brazuca Natal Study (p<0.05). In the Brazuca Natal Post-COVID-19 Study, these associations were not observed. Fasting blood glucose was associated with vitamin D deficiency only in the Brazuca Natal Post-COVID-19 Study (p<0.05).
We conclude that the population evaluated has a high prevalence of micronutrient inadequacy, with an emphasis on vitamin D, in addition to associations between its deficiency and changes in MS components, which vary between the Brazuca Natal and Brazuca Natal Post-COVID-19 studies.
