  1. Lower levels of physical functioning are associated with higher body weight among middle-aged and older women.

    Article - En anglais


    To compare levels of physical function, across levels of body mass index (BMI), among middle-to older-aged women.


    Cross-sectional study.

    Physical function, body weight and other covariates were measured in 1992.


    56 510 women aged 45-71 y, free of cardiovascular disease and cancer, participating in the Nurses'Health Study.


    The four physical function scores on the Medical Outcomes Study (MOS) Short Form36 (SF36) Health Survey : physical functioning, vitality, bodily pain and role limitations.


    After adjusting for age, race, smoking status, menopausal status, physical activity and alcohol consumption, there was a significant dose-response gradient between increasing levels of BMI in 1992 and reduced function.

    For example, women with a BMI between 30-34.9 kg/m2 averaged : 9.0 point lower physical functioning score (95% Confidence interval (CI) - 9.5, - 8.5), 5.6 point lower vitality score (95% CI : - 6.1, - 5.1), and 7.0 point lower freedom from pain score (95% CI : - 7.6, - 6.4).

    These declines represent an approximate 10% loss of function comoared to the reference category of women with BMls ranging from 22.0-23.9 kg/m2.

    For the same BMI comparison, heavier women were at 66% increased risk of limitations in ability to work or perform other roles (RR=1.66 ; 95% odds ratio (OR) Cl : 1.56,1.76). (...)
