Serum 25-hydroxyvitamin D3 is related to fish intake and exercise in Korean adult men.
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.
