Objective: The purpose of this study was to evaluate prevalence of osteopenia in young Non- athletic women. Methods: Forty young untrained women between the age of 20-25 years (obese n=20, BMI over 30 and thin n=20, BMI below 18.5) volunteered to participate in this study. Bone mass density (BMD), percentage body fat and lean mass (g/cm2) were measured with the dual X-ray absorptiometry scans (DEXA). Student's t-test was used for determine the amount of bone normalization among subjects.Result: The study findings showed that 20% of obese and 65% of thin women had Osteopenia. Thin women were 3.2% more at risk of developingosteopenia compared to obese group .Conclusion: These findings will help educate the medical community and the public about the importance of prevention targeting young women who are at risk while they still have time to change their habits and improve their bone health.Key words: Osteopenia, Bone mass density, Non-athletic women.
