Abstract
Vitamin D status is influenced by sun exposure, geographic latitude, daily outdoor activities, body surface exposed to sunlight and dietary intakes. Malaysia, is sunny all year round. However, the vitamin D status of this population especially among the healthy and free living adults is not known. Therefore a study of vitamin D status and associated factors was initiated among an existing Malay cohort in Kuala Lumpur. A total of 380 subjects were sampled to have their vitamin D status assessed using 25-hydroxyvitamin D (25(OH)D). A short questionnaire enquiring socio-demographic characteristics, exposure to sunlight and clothing style was administered. Their mean age was 48.5 ± 5.2 years and the mean 25(OH)D for males and females were 56.2 ± 18.9 nmol/L and 36.2 ± 13.4 nmol/L respectively. There were significant positive correlation for sun exposure score (r = 0.27, p < 0.001) and negative correlation for sun protection score (r = -0.41, p < 0.001) with 25(OH)D levels. In the logistic regression model, females (OR = 2.93; 95 CI: 1.17, 7.31), BMI (1.1; 1.03, 1.20) and sun exposure score (0.998; 0.996, 0.999) were significantly associated with vitamin D status as represented by 25(OH)D levels. Our findings show that obesity, lifestyle behaviours and clothing style are directly associated with our participants especially females' low vitamin D status. © 2011 Elsevier B.V.
