Ultrasound bone mineral density of Os Calcis - its relationship with bone mineral markers and 25(OH) vitamin D in endemic fluorotic and non-fluorotic villages

Objectives: To study the relationship between the nutritional status, serum bone mineral markers, 25 hydroxy vitaminD [25(OH)D] levels and ultrasound bone mineral density (USBMD) of Os Calcis in subjects living in endemic fluorotic and non-fluorotic villages. Methods: Subjects from fluorotic (n=57) and non-fluorotic (n=79) villages were studied for their dietary habits, biochemical parameters of bone mineral markers, 25(OH)D levels and correlated with stiffness index (SI) measured using Achilles ultrasound bone densitometer. Results: Dietary calcium intake in both the villages is far below the recommended daily allowances (RDA) by Indian Council of Medical Research (ICMR), India for Indian population. The 25(OH)D correlated positively with energy intake (r=0.7; p
