The present study has been conducted to examine the prevalence of osteopenia and osteoporosis among 190 adult girls ranging in age between 20 and 31 years, residing in the hostels of Panjab University, Chandigarh. T-scores of subjects were calculated utilizing Calcaneal Quantitative ultrasound (QUS) as diagnostic tool. Anthropometric variables namely height, weight, waist circumference, hip circumference were also taken on each subject by using standard techniques. Percent body fat, BMI and Visceral fat were measured by using body fat analyzer. ANOVA showed significant age group differences in all the parameters except for hip circumference, percent body fat, fat mass, fat mass index and BMI. The results revealed that the prevalence of osteoporosis and osteopenia among subjects was 7.37% and 64.21% respectively. According to the nutritional status of the subjects, maximum numbers of osteopenia cases were observed in normal (69.72%) category whereas, maximum numbers of osteoporotic cases were noticed in underweight (42.86) category and only 4.59% cases belonged to normal category. An improvement in bone density was observed in girls with increase in age. In the present study, BMD was found to be positively correlated with all the anthropometric measurements and indices except for height. Chi-square test showed that nutritional status and fracture in past, significantly affected bone mineral density of the girls included in the present study. Regression analysis revealed significant prediction of BMD by WC, WHtR, BMI, Weight, FM, VFA, FMI, FFMI, HC, FFM, PBF and WHR. Of all the variables, waist circumference (10.3%) is found to be the best predictor of BMD followed by WHtR (9.1%). Results of the present study are quite alarming and indicate towards an increase in the prevalence of osteoporosis if not checked at younger ages.
