Abstract

Background: Determinants of vitamin D status are of growing interest as vitamin D is now recognized to play an important role in overall health and decreases the risk of diseases such as osteoporosis, cancer, and cardiovascular disease. Understanding modifiable determinants of vitamin D status is necessary to increase the possibilities of improving vitamin D deficiency. Aim: The aim of this study is to determine the frequency of deficiency and insufficiency of vitamin D in a sample of apparently healthy children aged 12-36 months in relation to anthropometric measurements and other modifiable determinants. Methodology: A cross-sectional study with concurrent measurement of dietary, lifestyle and anthropometric exposures as well as 25(OH)D level was performed, in which 126 children between 12 and 36 months of age were studied at their first visit to Ard El Insan (AEI) clinics in Gaza and Khanyounis cities between April and May 2013. Results: The prevalence of vitamin D deficiency and insufficiency was 37.3% and 21.4% respectively. The risk of having lower vitamin D levels was 8.6 times more in children exposed to sunlight less than 15 minutes/day when compared with children exposed to sunlight for durations more than 15 minutes/day, (OR=8.587, 95% CI=3.178-23.206). Overweight children were significantly more likely to have lower vitamin D levels (OR=12.253, 95% CI=1.383-108.589) than underweight to normal weight children. Children with dietary vitamin D intake less than 250 IU per day were 8 times more likely to have lower vitamin D levels compared to those with daily vitamin D intake ≥250 IU (OR=8.317, 95% CI=2.344-29.513). The likelihood of lower vitamin D status in children who participated in indoor activities and watched T.V. for more than 8 hours per day was significantly higher (OR=10.398, 95% CI=1.783-60.632) relative to children who participated in indoor activities for shorter durations. Conclusion: Subclinical vitamin D deficiency is commonly undiagnosed and is an unrecognized epidemic among children in the Gaza Strip. Given the results of this study, overweight, indoor activities, poor dietary intake of vitamin D and behaviors that decrease skin exposure to direct UVB radiation were associated with the vitamin D deficient state and increased the odds for vitamin D deficiency in this group of children. Therefore it may be beneficial to require a higher oral intake of vitamin D for vulnerable groups. Keywords: Vitamin D, Determinants, Anthropometric measurements, Gaza Strip, Children.
