To investigate the needed, unneeded and unmet health care services among rural community-dwelling older adults in China and examine the influencing factors, aiming to facilitate the global development of the home care system for a healthier world. This cross-sectional study investigated rural areas in three provinces in Western China. A total of 1727 rural community-dwelling older adults were enrolled. The needed, unneeded and unmet health care services were assessed by the Supply and Demand of Health Care Services (SD-HCS) questionnaire for older adults. Respect (73%, 1265/1727) was the most needed. The other top 9 needed mainly belonged to the divisions of health monitoring and information regarding chronic diseases. Re-employment or part-time jobs (71%, 1230/1727) was the most unneeded. All five protection and safety items were the most unmet but needed. Religion was the main influencing factor of those health care services that were less unmet but needed. Respect was basic for older adults, and chronic disease management was in great demand among rural community-dwelling older adults. Due to low willingness and the crisis workforce, a more flexible retirement policy is needed in rural China. It is urgent to improve the emergency care system in rural areas. Last but not least, more research is needed to explore the association between religion and health. Copyright © 2021 Elsevier Inc. All rights reserved.
