The association between obesity and severe disability among adults aged 50 or over in nine high-income, middle-income and low-income countries: a cross-sectional study.
Bottom Line: Compared to normal BMI (18.5-24.9 kg/m(2)), BMI≥35 kg/m(2) was associated with significantly higher odds for ADL disability in Finland (OR 4.64), Poland (OR 2.77), South Africa (OR 2.19) and Spain (OR 2.42).Interaction analysis showed that obese individuals in high-income countries were more likely to have ADL limitations than those in low-income or middle-income countries.The higher odds for disability among obese individuals in high-income countries may imply longer life lived with disability due to factors such as the decline in cardiovascular disease mortality.

Mentions: Figure 1 illustrates the prevalence of ADL limitations by BMI category. A clear dose-dependent relationship between BMI and ADL limitations was observed in Finland, Poland and Spain. The prevalence (95% CI) of limitations in ADL when using lower cut-offs for Asia were 1.6% (1.2% to 2.2%), 1.4% (1% to 1.9%) and 1.4% (0.8% to 2.2%) for BMI 18.5–22.9 kg/m2, 23.0–27.4 kg/m2, and ≥27.5 kg/m2, respectively in China. The corresponding figures for India were 10.7% (8.7% to 13%), 11.8% (9% to 15.3%) and 10.1% (6.7% to 15%). The association between BMI and ADL limitations estimated by multivariable logistic regression is shown in table 2. With the exception of China, a trend for higher BMI to have stronger associations with ADL limitations compared to normal weight was observed in most countries although this association was not significant in some. In China, a non-significant trend for a decrease in the odds for ADL disability with higher BMI was observed.
