Vitamin D is an important factor for bone health. It is uncertain which lifestyle is associated with vitamin D status, especially in healthy middle aged Asian men. A cross-sectional analysis was performed in 149 men aged 40-69 years who visited a health check-up center in Korea. Serum vitamin D (25-OHD3) was measured and smoking, alcohol, exercise, occupation, frequency of fish and dairy intake were estimated by self-administered questionnaire. The mean (+/-SD) 25-OHD3 concentration was 96.5+/-30.7 nmol/L. Higher and lower 25-OHD3 groups were generated with the median concentration as the cut-off point. By univariate analysis, exercise status and fish intake frequency were significantly different between two 25-OHD3 groups (p=0.012, 0.019 respectively). After multivariable logistic regression, higher fish intake frequency and regular exercise were associated with higher levels of 25-OHD3 (p for trend=0.017 and 0.02 respectively). In conclusion, frequent fish intake and regular exercise are positively associated with serum 25-OHD3 concentrations in healthy Korean men.
维生素D是骨骼健康的重要因素。目前尚不确定哪种生活方式与维生素D水平相关，尤其是在健康的中年亚洲男性中。对149名年龄在40至69岁之间、前往韩国一家健康体检中心的男性进行了横断面分析。通过自我填写问卷评估吸烟、饮酒、运动、职业、鱼类和乳制品摄入频率，并测量血清维生素D（25-羟基维生素D3）。25-羟基维生素D3的平均（±标准差）浓度为96.5±30.7nmol/L。以中位数浓度为分界点，划分出较高和较低的25-羟基维生素D3组。通过单因素分析，两组25-羟基维生素D3组之间的运动状况和鱼类摄入频率存在显著差异（分别为p = 0.012、0.019）。经过多变量逻辑回归分析，较高的鱼类摄入频率和规律运动与较高水平的25-羟基维生素D3相关（趋势p值分别为0.017和0.02）。总之，在健康的韩国男性中，频繁摄入鱼类和规律运动与血清25-羟基维生素D3浓度呈正相关。
