ABSTRACT
<p><b>OBJECTIVE</b>This study aims to assess the status of successful aging (SA) in longevity areas in China and explore multiple factors associated with SA among the young-old and oldest-old.</p><p><b>METHODS</b>A total of 2296 elderly people aged 65 and older were interviewed in the longevity areas sub-sample of the Chinese Longitudinal Healthy Longevity Survey (CLHLS) in 2012. Baseline assessments included a researcher-administered questionnaire, physical examination, and laboratory testing. A logistic regression model was used to identify factors associated with SA.</p><p><b>RESULTS</b>The prevalence of SA was 38.81% in the CLHLS in 2012. There were significant differences between ages groups, with SA compromising 56.85% among ⋝65 years group and 20.31% among ⋝100 years group (χ2trend=126.73, P<0.01). The prevalence of SA among females was 33.59%, which was significantly lower than that among males (45.58%) (χ2gender=33.65, P<0.05). In the regression analysis, having anemia (OR=0.744, 95% CI: 0.609-0.910), poor lifestyle (OR=0.697, 95% CI: 0.568-0.854), poor sleep quality (OR=0.558, 95% CI: 0.456-0.682), and central obesity (OR=0.684, 95% CI: 0.556-0.841) were the main factors associated with SA. The promoting SA rate decreased as age increased, and the group of 65-79 years had higher odds than the other age group.</p><p><b>CONCLUSION</b>Preventing central obesity, improving sleep quality and promoting healthy lifestyle may contribute to achieve SA among the elderly.</p>
