  1. Physical activity in adolescence and bone density in peri-and postmenopausal women : A population-based study.

    Article - En anglais

    The association between sports participation during adolescence and peri-and postmenopausal bone mineral density (BMD) was examined among 2025 women aged 48-58 years.

    Adolescent recreational and competitive sporting activities were registered with a self-administered questionnaire.

    Altogether, 881 (43.5%) women stated that they had taken part in sports during their adolescence.

    BMD was measured using dual X-ray absorptiometry (DXA) in lumbar vertebrae 2-4 and the left femoral neck.

    The unadjusted BMD was 2.4% higher (p=0.001) and the adjusted BMD was 1.4% higher in the spine (p=0.015 after adjusting for age, weight, time from menopause to densitometry, and duration of estrogen replacement therapy) among women who had taken part in sports during their adolescence compared to women who had been inactive.

    There was no significant difference in femoral neck BMD between these groups.

    The results of this population-based study suggest that intense recreational physical activity in adolescence could play some role in preventing axial osteoporosis in later life.
