Aim To investigate the relationship between waist circumference ( WC ) and activities of daily living ( ADL )/instrumental activities of daily living ( IADL ) disability among nonagenarians and centenarians. Methods We analyzed data obtained from a cross‐sectional study carried out in 870 older C hinese adults aged 90 years and older in D ujiangyan, a town in W est C hina. The participants were divided into four groups according to their sex and WC quartile. The ADL and IADL disabilities were measured using the physical self‐maintenance scale and L awton and Brody's IADL scale, respectively. Results We included 233 men and 505 women in this statistical analysis. The prevalence of ADL or IADL disability was 53.6% in men and 71.3% in women. Participants in the highest WC quartile group ( WC ≥83.0 cm for men or WC ≥82.0 cm for women) had higher prevalence of ADL or IADL disability compared with those in the lowest WC quartile group ( WC <73.0 cm for men or WC <70.5 cm for women). Adjusting for relevant confounders, the highest quartile group showed significantly increased odds ratios for either ADL (1.7 for men and 2.1 for women) or IADL disability (odds ratios 3.3 for men and 2.0 for women) compared with the lowest quartile group. Conclusion Among Chinese older adults aged 90 years and older, both men and women in the highest quartile of WC were at higher risk of ADL or IADL disability compared with those in the lowest quartile of WC .
