  1. Body weight and mortality : a prospective evaluation in a cohort of middle-aged men in Shanghai, China.

    Article - En anglais

    Background The relationship between relative body weight and mortality has been well studied in Western populations and remains controversial.

    Little is known about the weight-mortality association in less well fed people in developing countries.

    Methods A cohort of 18 244 Chinese men aged 45-64 years in Shanghai, China enrolled in a prospective study of diet and cancer during January 1986 through September 1989.

    At recruitment, height and usual body weight were collected through interview.

    An active, annual follow-up of the cohort was conducted for cancer and death.

    Proportional hazards regression method was used to examine the relation between body mass index (BMI, weight in kg/height in m2) and overall and cause-specific mortality.

    Results By 28 February 1995,1198 deaths (498 from cancer, 422 from cardio-and cerebrovascular disease, and 278 from other causes) had been identified.

    We found a U-shaped relation between BMI and total mortality among lifelong non-smokers.

    Compared with non-smokers with BMI 21.0-<23.5, the relative risk (RR) for all cause mortality was 1.73 (95% confidence interval [CI] : 1.23-2.42) for men with BMI<18.5 and 1.48 (95% CI : 1.07-2.03) for men with BMI >=26 after adjustment for age, level of education, and alcohol drinking.

    The elevated risk of death in men with BMI >=26 was largely due to fatal cardio-and cerebro-vascular diseases. (...)
