Although laboratory workers is constantly increasing every year, there is few study on the health and nutritional status of research workers. The purpose of this study was to determine the health status for laboratory workers by analyzing dietary habits and blood clinical indices.
The subjects were 100 female laboratory workers. This study investigated the anthropometric parameters, clinical blood indices, dietary intake, and questionnaire. Subjects were divided into two group according to duration of laboratory work(< 1 year, 1 year ?). In addition, we investigated the nutritional status of the vitamin D in laboratory workers and were divided into two groups who have <10ng/mL, 10ng/mL? by the serum 25-(OH)-Vitamin D concentration. The average age and BMI of subjects were 23.18years and 21.51kg/m2. The over 1 year(1 year ?) group was significantly higher than the less than 1 year(< 1 year) group in Waist-hip ratio. The mean serum vitamin D level of all subjects was 10.04ng/mL which is close to the WHO standard vitamin D deficiency level. There was significantly higher average intake of energy in the over 1 year group compared to the less than 1 year group. The mean ratio of calories from carbohydrate: protein: fat was 54.4:14.7:30.9. The mean intake of vitamin D of all subjects was insufficient to less than 30% of adequate intake(AI). They did not have enough time to have a meal and they had a meal very irregularly. The frequency of sweet snack showed that there was a significant higher in the over 1 year group.
The less than 10ng/mL(<10ng/mL) group was a significantly higher than the over 10ng/mL(10ng/mL?) group in body fat percentage and visceral fat. Cardiovascular-related indices showed significantly higher level of CRF in the less than 10ng/mL(<10ng/mL) group. Serum 25-(OH) vitamin D concentration was significantly increased according to sunlight. It revealed a positive correlation between serum 25-(OH) -vitamin D concentration and exposure time to sunlight while dietary intake of vitamin D did not show positive correlation with serum 25-(OH)-vitamin D levels
In conclusion, laboratory workers are a very high risk group in terms of nutritional status of vitamin D. Therefore, they need more exposure time to sunlight as well as dietary consumption of vitamin D. In addition, it is important for laboratory worker to practice regular and balanced dietary habits in order to maintain a healthy life.
