Abstract

Background: It is unclear to what degree centenarians are successful agers. We assess successful aging (SA) and its subtypes in a large Chinese sample.

Methods: Based on a large national sample of 18,311 Chinese centenarians, we first estimated the prevalence of SA among centenarians, and then used the Latent Class Analysis to classify centenarians into different types based on the five dimensions of SA. Multinomial regression analysis was used to examine how demographic, socioeconomic, and lifestyle covariates are associated with these identified types.

Results: 5.7% of centenarians fulfilled all five criteria of SA, and 1.3% failed all five criteria. The remainder could be classified into six types of SA. The regression analysis further revealed that these SA types were related to various social factors. For example, with timely access to medical care, centenarians were three times more likely to be successful agers.

Conclusions: Centenarians demonstrate substantial heterogeneity in terms of achieving five SA criteria. Social factors are found to be significantly associated with centenarians' aging performances. Specific subtypes of SA among centenarians may be associated with and help explore different underlying biological-environmental mechanisms of exceptional longevity.

Keywords: China; centenarian; longevity; oldest-old; successful aging.
