            This is a descriptive cross-sectional study aimed to investigate work ability and associated factors of aging healthcare workers. The samples obtained from stratified sampling were 285 healthcare workers aged 45 and older who worked in Nopparat Rajathanee hospital. Work ability was assessed by a Work Ability Index questionnaire (WAI) Thai version and associated factors were assessed by a questionnaire that had a content validity index of 0.99 and Cronbach’s alpha coefficient of 0.81. Work ability scores were presented in mean and standard deviation while categorical variables were presented in number and percentage. Those associated factors to work ability were analysed by multiple logistic regression and presented as crude and adjusted odds ratios (ORs).
            According to the results of the present survey, the mean score of the WAI was 38.8 (SD = 4.50). Most samples obtained work ability at a “Good” category (58.2%). Factors significantly associated to poor work ability included physicians (ORadj = 12.36, 95% CI = 2.15 - 71.00), history of smoking (ORadj = 11.43, 95% CI = 1.78 - 73.36), ergonomics problems in working environment (ORadj = 4.22, 95% CI = 1.80 - 9.90), and conflict in family (ORadj = 2.63, 95% CI = 1.14 - 6.06). Protective factors significantly associated to poor work ability included males (ORadj = 0.06, 95% CI = 0.01 - 0.32), the highest education level more than bachelor,s degree (ORadj = 0.37, 95% CI = 0.14 - 0.93), and more income (every 1,000 baht) (ORadj = 0.95, 95% CI = 0.92 - 0.99). Therefore, we should focus on this situation and find ways to increase work ability by improving the factors that are associated to work ability of aging healthcare workers, such as launching a campaign to stop smoking, improving the working environment especially in ergonomics problem.
