Effect of variable diet and physical activity on bone mineral density in adults using peripheral-Dexa scan

The study was conducted to detect and compare BMD (Bone mineral density)in adults of variable diet and physical activity by using Pixi Lunar Heel Densitometer that uses dexa(Dual energy x-ray absorptiometry) technique. Methodology: This is across-sectional observational research work to measure the mineral density of the heel bonein 173 individuals who attended orthopedic health camp conducted by Kasturba Medical College (KMC), Mangalore, Manipal Academy of Higher Education (MAHE), Karnataka, India. Results: Depicted as Mean ± SEM.p² 0.05 was taken as statistically significant. 89individuals had some exercise historyand the remaining 104 were not having exercise history. Among 173 individuals 32 were consuming vegetarian diet and remaining 141 consumed mixed diet. Subjects with history of exercise had mean BMD of 0.48gm/cm2 and subjects without history of exercise were having mean BMD of 0.465gm/cm2(NS). Vegetarians had mean BMD of 0.46 gm/cm2 and people having mixed diet had mean BMD of 0.48gm/cm²(NS).
