Vitamin D is a micronutrient that plays a key role in phosphocalcic metabolism. The postmenopausal population presents a risk of deficiency in this vitamin due to hormonal alterations which, in the case of obesity, would be exacerbated. The objective was to assess the status of vitamin D in a postmenopausal population and determine the relationship of 25-hydroxivitamin D [25(OH)D] and its metabolites with anthropometric parameters. The study included 78 healthy postmenopausal women aged from 44 to 76. The nutrient intake assessment was carried out using the 24 h reminder (R24h). 25(OH)D was analyzed using ultra-high-performance liquid chromatography (UHPLC). A total of 80% and 68% of the women studied did not reach sufficient values of 25(OH)D and 25-hydroxivitamin D 3 [25(OH)D 3 ], respectively, which was inversely correlated with Body Mass Index (BMI) ( r = -0.25, p = 0.04), hip perimeter ( r = -0.26 and r = -0.24, all p &lt; 0.05), arm circumference ( r = -0.29, p = 0.01) and fat mass ( r = -0.28 and r = -0.26, all p &lt; 0.05). 25(OH)D 3 is the metabolite that contributed most to this association. In conclusion, 25(OH)D 3 levels are related to anthropometric parameters in the postmenopausal women in this study, confirming insufficient status in the majority of the population. Approach strategies are necessary to correct and avoid this risk in order to ensure future quality of life.
