  1. Physical activity and bone mineral density in italian middle-aged women.

    Article - En anglais

    Osteoporosis is a major health issue in postmenopausal women on account of the association between low bone mineral density and fractures.

    A role of physical activity in the prevention and treatment of low bone mineral density is possible but still unclear.

    The relationship between low spine bone mineral density measured by means of dual photon absorptiometry at lumbar spines, and levels of past and recent physical activity has been assessed by means of a population-based screening study carried out on 1373 women (age 40-64 years) in the North-East of Italy.

    Physical activity at work and in leisure time was investigated for three specific periods of life : at age 12, between 15 and 19 years (during bone formative years), and in the recent years prior to the interview (30-39 or 50-59 years).

    Data were analysed comparing low versus high bone mineral density tertile (i.e., 458 and 461 women, respectively), after controlling for other known contributory factors in the development of osteoporosis.

    A positive association emerged with leisure time physical activity, with significant trends at age 15-19 (odds ratio (OR) for low versus high tertile of leisure time activity : 1.4,95% confidence interval (CI) : 0.8-2.4) and at most recent age (OR : 1.7,95% CI : 1.1-2.6).

    Risk trends with occupational physical activity were less clear and non-statistically significant. (...)
