High Proportion of Vitamin D Deficiency in Male Adolescents in Yogyakarta Indonesia
Abstract
Deficiency of vitamin D in the world is high. Vitamin D deficiency has numerous negative effects. The purpose of this study was to determine the proportion of vitamin D deficiency in male adolescents in Yogyakarta Indonesia. This research is a cross-sectional study. The height, weight, physical activity, lipid profile laboratory data and vitamin D levels of subjects were recorded in the study. Body mass index (BMI) is calculated as body weight divided by height. Moderate exercise in physical is determined as enough activity for 150 minutes in week for moderate exercise and 75 minutes in week for strenuous exercise. Dyslipidaemia is diagnosed as an abnormal lipid level of three criteria: LowDensity Lipoprotein (LDL) ≥140 mg/dl, High-Density Lipoprotein (HDL) <40 mg/dl, and triglyceride ≥150 mg/dl. Vitamin deficiency was determined using the enzymes linked immunoassay method by measuring the activity of 25hydroxy vitamin D using serum samples of subjects. A total of 60 male adolescents aged 19–25 years participated in the study. A total of 30 subjects (50%) had obesity with an average BMI of 29.65 kg/m2. A total of 38 subjects had increased dyslipidaemia, with the highest proportion having low HDL (15%). A total of 39 subjects (65%) had had sufficient physical activity. The proportion of vitamin D deficiency was experienced by 26 subjects (43.3%) while the proportion of vitamin D insufficiency was experienced by 31 subjects (51.7%). Statistical analysis showed there was no correlation between the occurrence of vitamin D deficiency and obesity, dyslipidaemia and physical activity (Χ = 0.778, p = 0.6779; Χ = 1.8, p = 0.4065; Χ = 0.087, p = 0.575). Proportion of vitamin D deficiency and insufficiency was quite high among male adolescents but not related to physical activity. Interventions are needed to treat conditions of vitamin D deficiency and insufficiency.
