Abstract: Background　As the number of Chinese elderly people's life expectancy lengthens，they may live with an illness for a longer period. For the large number of Henan older adults，chronic diseases have become a major challenge to daily living. Objective　To assess the comprehensive ability and chronic disease prevalence，and to examine the relationship between them in Henan older adults. Methods　This study was implemented between January and September 2019. By use of multistage stratified random sampling，permanent residents（≥60 years old） were selected from 18 provincial cities of Henan province to attend a interviewer-administered survey to collect general health information（prevalence of chronic diseases，such as hypertension，diabetes，coronary heart disease，chronic obstructive pulmonary disease，malignant tumor，stroke，and so on） using a health information questionnaire developed by us，and to obtain information about comprehensive ability 〔intact ability，or comprehensive disability （mild，moderate or severe）〕 using the Ability Assessment for Older Adults （MZ/T 039—2013） . Binary logistic regression analysis was used to identify factors associated with comprehensive ability. Results　In total，6 094 attended the survey，and 5 570 of them who responded effectively were included for final analysis. Among the respondents，the prevalence of intact ability，and comprehensive disability was 49.55%（2 760/5 570），50.45%〔2 810（including 2 291 cases of mild disability，340 cases of moderate disability，and 177 cases of severe disability）/5 570〕，respectively. The prevalence of having no chronic diseases，one，two，three，four，five，six and seven chronic diseases，was 48.67%（2 711/5 570），33.03%（1 840/5 570），12.30%（685/5 570），3.16%（176/5 570），0.59%（33/5 570），0.63%（35/5 570），1.15%（64/5 570），and 0.47%（26/5 570），respectively. The prevalence of hypertension，diabetes，coronary heart disease，chronic obstructive pulmonary disease，cancer，stroke and other chronic diseases was 34.49%（1 921/5 570），11.97%（667/5 570），12.41%（691/5 570），3.99%（222/5 570），2.85%（159/5 570），4.97% （277/5 570），and 12.10%（674/5 570），respectively. Binary Logistic regression analysis showed that cancer 〔OR=0.537，95%CI （0.319，0.904）〕，number of coexisted chronic conditions 〔one：OR=2.520，95%CI （1.715，3.702）； two：OR=3.859，95%CI （1.825，8.163）； three：OR=7.388，95%CI （2.381，22.928）〕 were associated with comprehensive ability （P<0.05）. Conclusion　In Henan older adults，the prevalence of disability was high，and the comprehensive ability was unsatisfactory. The coexistence of multiple conditions may be associated with the comprehensive ability.
