Abstract:
〈 b 〉 〈 i 〉 Objectives: 〈 /i 〉 〈 /b 〉 The objectives of this study were to examine whether weight loss, weight status (based on body mass index [BMI] categories), and abdominal obesity (based on waist circumference [WC] ) were associated with a 17-year mortality risk in community-dwelling older adults. 〈 b 〉 〈 i 〉 Methods: 〈 /i 〉 〈 /b 〉 Participants were 2,017 community-dwelling adults aged 65 years or above in the longitudinal Enquête de Santé Psychologique-Risques, Incidence et Traitement study. Self-reported weight loss was collected at baseline during face-to-face interviews. Bodyweight (kg), height (m), and WC (cm) were independently measured at the baseline. BMI was categorized as follows: underweight (BMI & #x3c;18.5 kg/m 〈 sup 〉 2 〈 /sup 〉 ), normal weight (18.5–24.9 kg/m 〈 sup 〉 2 〈 /sup 〉 ), overweight (25–29.9 kg/m 〈 sup 〉 2 〈 /sup 〉 ), and obese (≥30 kg/m 〈 sup 〉 2 〈 /sup 〉 ). Abdominal obesity was defined by a WC of ≥102 cm in men and ≥88 cm in women. Adjusted Cox proportional hazards models were used to examine associations of weight loss, weight status, and abdominal obesity with all-cause mortality. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 Over 17 years of follow-up (median 15.5 years), 812 participants died. Abdominal obesity compared to nonabdominal obesity was associated with a 49% increased mortality risk (95% confidence interval (CI): 1.22–1.83). However, being overweight (but not obese) was associated with a 20% decreased risk (95% CI: 0.66–0.97) compared to a normal BMI. Gender did not affect these associations. In the whole cohort, self-reported weight loss at baseline was not associated with an increased mortality risk after adjusting for health and lifestyle factors. However, in men, a baseline self-reported recent weight loss of & #x3e;3 kg was associated with a 52% increase in mortality risk (95% CI: 1.05–2.18) in a fully adjusted model. 〈 b 〉 〈 i 〉 Conclusion: 〈 /i 〉 〈 /b 〉 In community-dwelling adults aged ≥65 years, abdominal obesity was strongly associated with increased mortality risk. Being overweight appeared, however, to be protective against mortality. Modest self-reported weight loss was not associated with all-cause mortality in community-dwelling older adults after adjusting for health and lifestyle factors. However, men reporting recent weight loss of more than 3 kg may be at increased risk. The findings of this study support the use of WC, rather than BMI, as a predictor of mortality risk in older adults.
