STUDY DESIGN AND OUTCOME VARIABLES: This study used data from four waves of the Chinese Longitudinal Health and Longevity Survey (CLHLS) conducted in 2002, 2005, 2008 and 2011. The sample comprised 2137 older adults who were interviewed in 2002 and re-interviewed in the following waves. Cross-tabulations were run to show the rise in chronic disease and disability with age. Ordinal logistic regression was run to examine the debilitating effects of these diseases in terms of the ability of the oldest old to perform activities of daily living.
RESULTS: The prevalence of chronic diseases rose sharply with age. The prevalence rate of six major diseases increased between 38% (respiratory diseases) and 533% (neurological disorder) among respondents who were re-interviewed nine years later. Cardiovascular diseases were the most common. Neurological disorder and cancer were less common, but had the most debilitating effects on patients. Overall, 10.0%, 3.1% and 3.1% of the respondents were disabled by cardiovascular, musculoskeletal and sensorial diseases, respectively. Ordinal logistic regression showed that neurological disorder had the strongest debilitating effects, followed by musculoskeletal and cardiovascular diseases among 2137 older persons who had survived and were followed up from the base year (2002) through 2011.
CONCLUSION: The rapid rise in chronic diseases has resulted in an increased burden of disability among the oldest old in China. There is a need to improve health care systems for the prevention and management of chronic diseases.
METHODS: Data for this analysis came from 2002, 2005, 2008 and 2011 waves of the Chinese Longitudinal Healthy Longevity Survey (CLHLS). We used a random intercept multilevel multinomial logit model to analyze data from 3208 older adults aged 65 from the 2002 wave, which decreased to 1385 in 2011. The main study variable is older adults' engagement in paid jobs and unpaid work (including housework, care-taking, poultry farming, and planting vegetables that have an economic value).
RESULTS: There was a strong association between older adults' productive engagement and their functional limitations to daily living activities, health and healthy behavior. Older adults with inadequate finance were more likely to be working to support themselves. Those who exercised less and living in the provinces with higher GDP were less likely to work post-retirement. Chronic diseases, advances in age, no education and rural residence did not deter older adults from doing unpaid work.
CONCLUSION: Older adults in China were actively engaged in paid and unpaid activities. Efforts to support the active engagement of older adults require all stakeholders to promote healthy living, facilitate social engagements and provide an age-friendly work environment.
