Abstract
Background:Many studies show a high prevalence of vitamin D deficiency across various populations the world over. There is relative lack of prevalence data in Punjab, India. This cross-sectional study was carried out to assess the prevalence of vitamin D deficiency in the north-west Punjab population.Aim:To study the prevalence of vitamin D deficiency in the north-west Punjab population across various population characteristics such as gender, education, locality, occupation, and dietary habits.Materials and Methods:Healthy volunteers (N = 150) of either sex were enrolled and their fasting plasma samples tested for 25-hydroxy vitamin D [25(OH) D] levels. Data were compiled as percentages and means across different population characteristics. Statistical analysis was done using Chi-square test and Fisher's exact test.Results:A high overall prevalence (90%) of vitamin D deficiency was observed in the study subjects. There was a significant difference in the prevalence of vitamin D insufficiency between rural and urban subjects (P < 0.05) and among the subjects pursuing different occupations (P < 0.001). A significant gender-specific difference was also recorded at the cut-off level of 25 (OH) D, with women showing higher prevalence of deficiency compared to men (P < 0.05).Conclusions:There is a high prevalence of vitamin D deficiency in the population of Punjab. Lower prevalence is displayed by those subjects who have greater opportunities for sunlight exposure, such as like rural individuals, farmers, and housewives.
