维生素D缺乏症在世界范围内普遍存在。我们调查了维生素D摄入量和紫外线（UV）暴露对日本血清维生素D浓度的影响。从北海道（北纬43度）和熊本（北纬33度）县共招募了107名健康成人参与者。所有参与者都在夏季和冬季进行了调查。检测血清25-羟基维生素D（25（OH）D-3），并通过饮食史问卷评估维生素D摄入量。用可穿戴的UV剂量计测量UV暴露。进行回归分析，以调查这些因素之间的关系，协变量，如太阳回避行为。维生素D不足的患病率（血清25（OH）D-3; 12 ng/mL（30 nmol/L））
Vitamin D insufficiency/deficiency is prevalent worldwide. We investigated the effect of vitamin D intake and ultraviolet ray (UV) exposure on serum vitamin D concentration in Japan. A total of 107 healthy adult participants were recruited from Hokkaido (43 degrees N) and Kumamoto (33 degrees N) prefectures. All participants undertook surveys in both summer and winter. Serum 25-hydroxyvitamin D (25(OH)D-3) was examined, and vitamin D intake was assessed with a diet history questionnaire. UV exposure was measured with a wearable UV dosimeter. Regression analysis was performed to investigate the relationship between these factors, with covariates such as sun avoidance behavior. The prevalence of vitamin D insufficiency (serum 25(OH)D-3; 12 ng/mL (30 nmol/L)
