To explore the associations of central obesity indicators including waist circumference (WC), waist-to-height ratio (WHtR), and weight-adjusted index (WWI) with impairment basic activities daily living (BADL) instrumental (IADL) among middle-aged elderly population in China. This prospective study used baseline data from 2011 follow-up data, involving 6440 9646 participants, respectively. Binary logistic regression analysis was to assess relationships. Restricted cubic spline (RCS) curve also analyze correlation trends. Stratified analyses were performed identify potential differences. Receiver operating characteristic curves plotted evaluate predictive value each indicator. WC (OR = 1.01, 95% CI:1.01-1.02), WHtR 1.21, CI 1.09-1.33), WWI 1.10, CI:1.02-1.19) significantly associated BADL impairment. Only 1.16, 95%CI:1.09-1.23) IADL WC, linearly while The risk association between stronger drinking individuals males. In participants a BMI less than 24 kg/m² who had received high school education or above, increase accompanied by more significant ability is higher that WHtR, AUC values 0.597 0.615. WWI, as comprehensive indicator obesity, may be useful comprehensively identifying early activity population.
