Influence of Age at Menarche on Bone Mineral Density of Rural Women

The primary estrogen, estradiol plays a crucial role in bone formation and after the onset of menarche in girls influences the bone growth and is the base for determining the peak bone mass in late adolescence years. Thus the onset of menarche is crucial in determining the bone health status of women in later years. In this regard, the present study is focused to test the influence of age at menarche in the life of adulthood. Rural women with  age range of 35 to 74 years (n=260) are selected and evaluated for the influence of age at menarche by considering menarche nature in terms of age at menarche as early, ideal and late . The present study results have demonstrated the late menarche is the major detrimental factor for poor bone mass. Early and ideal menarche conditions are associated significantly with greater retention of bone density among adults.
