Independent associations between weight status and disability in adults: Results from the health survey for England

SummaryObjectivesWhile direct links between obesity and some illnesses are well-established, there is a relative paucity of research on associations between obesity and disabilities. The aim of this study was to test for significant associations between overweight and obesity and the presence of a wide range of disabling conditions in adults, controlling for sex, age, education, social class, income, cigarette smoking status and alcohol consumption.Study designData were extracted from the Health Survey for England (2001); a cross-sectional survey of the community-dwelling population. In total, 8613 adult participants were included in the analysis.MethodsMultivariate logistic regression was employed to test whether the odds of having a range of disabling conditions are higher in the overweight and obese populations compared with those in the ideal weight range.ResultsThe risk of nearly all disabling conditions tested was elevated in the obese and morbidly obese groups. Of great importance for public health, the risks of musculoskeletal illness, arthritis and rheumatism, and personal care disability were significantly elevated, even in those in the overweight category (currently about half of the adult population living in the UK).ConclusionsObesity is independently associated with a range of disabling conditions in adults. The present study highlights the need for further research into the mechanisms by which these associations occur.
