Effects of passive smoking on bone mineral density in premenopausal women

Objective To observe the impact of passive smoking on bone mineral density in premenopausal women.Method Altogether 394 premenopausal women were selected from out-patient department in the Department of Gerontology Zhongshan Hospital of Xiamen University.Their passive smoking exposure behaviors were inquired,their corresponding passive smoking exposure indexes were calculated,and simultaneously the bone density,in left side femur neck,great rotator and words triangle were measured.With variance and covariance analysis,analysis of the impact of passive smoking on bone mineral density.Results Among the 394 Premenopausal women;Passive smoking women each part(left side femur neck,great rotator and words triangle) bone mineral density decreased with increasing smoking index,the passive smoking exposure resulted in decreased bone density as compared with the non-exposure females.Conclusions Passive smoking can lead to decreased bone mineral density in premenopausal women.Its influence and passive smoking index are positively related.Passive smoking has similar adverse effects on bone density as the active smokers,In order to prevent osteoporosis,smoking should be inhibited.It is important to keep a clear living environment without passive smoking exposure.
