To assess the prevalence of hypovitaminosis D, altered arterial blood pressure, and serum levels of glucose and lipids in community-dwelling women in the city of Ribeirão Preto, in the southeast of Brazil. This was a cross-sectional study of women aged 40-70 years old. Calcium intake and level of sun exposure were assessed by means of a questionnaire. A blood sample was used to determine glucose, lipid profile and 25-hydroxyvitamin D (25[OH]D) concentration. Ninety-one women were enrolled (age = 54.2 ± 7.1 years). The mean serum 25(OH)D concentration was 25.7 ± 8.9 ng/mL. A total of 24 (26.4%) women had 25(OH)D levels < 20 ng/mL. Seventy women (76.9%) had 25(OH)D levels < 30 ng/mL. Seventy-five women (90.4%) had inadequate calcium intake, and 61 women (67%) had appropriate sun exposure, 49 of whom (80.3%) had serum 25(OH)D levels < 30 ng/mL. This study indicates that even in community-dwelling women, living in a city with high sun exposure, serum levels of 25(OH)D > 30 ng/ml are hardly reached. Thus, it is probable that other intrinsic factors besides sun exposure may regulate the levels of vitamin D.
评估巴西东南部里贝朗普雷图市社区居住女性中维生素D缺乏症、动脉血压改变以及血糖和血脂水平的患病率。 这是一项针对40 - 70岁女性的横断面研究。通过问卷调查评估钙摄入量和阳光暴露水平。采集血样以测定血糖、血脂谱和25 - 羟基维生素D（25[OH]D）浓度。 共纳入91名女性（年龄 = 54.2 ± 7.1岁）。血清25(OH)D平均浓度为25.7 ± 8.9 ng/mL。共有24名（26.4%）女性的25(OH)D水平 < 20 ng/mL。70名（76.9%）女性的25(OH)D水平 < 30 ng/mL。75名（90.4%）女性钙摄入量不足，61名（67%）女性阳光暴露适宜，其中49名（80.3%）女性的血清25(OH)D水平 < 30 ng/mL。 本研究表明，即使是居住在阳光照射充足城市的社区女性，血清25(OH)D水平 > 30 ng/ml也很难达到。因此，除阳光暴露外，可能还有其他内在因素调节维生素D水平。
