Demographic Differences and Trends of Vitamin D Levels Among the Teenaged Girls in Balochistan.

Background Vitamin D is a vital micronutrient and plays a vital role in defining the bone mineral density of an individual. There are many factors that regulate the levels of vitamin D in our body. The deficiency in vitamin D leads to various complications, with the most important one weakening of bones. Adolescence defines the degree of bone mineral density, which reduces with the growing age in a gradual fashion. Methods The study was a cross-sectional study conducted in Zarghoon town, Quetta, Pakistan. A sample size of 142 was taken from urban and rural areas. Participants were adolescent girls falling in the age bracket of 13-18 years. The circulating level of 25-hydroxy vitamin D was assessed using the ELISA (enzyme-linked immunosorbent assay) technique. Data were analyzed with SPSS Version 20 (IBM Corp.). Results Overall, vitamin D deficiency was 32.4%, and 9.9 % of girls were found to be severely deficient, where the highest proportion belonged to urban samples. The prevalence rate of vitamin D insufficiency was 39.4%. The urban population had a higher prevalence of low levels of vitamin D. In urban respondents, 49.1% had an insufficient vitamin D level, 33.3% had a deficient vitamin D level, and 17.5% had a severely deficient vitamin D level. In rural respondents, 47.1% had normal vitamin D levels, 32.9% had insufficient vitamin D levels, 15.3% were deficient, and 4.7% were severely deficient. Conclusion It was concluded that vitamin D deficiency has a high prevalence among adolescent girls of school age. Additionally, it is more prevalent in urban areas than in rural areas.
