BackgroundPrevious studies have concentrated on predictors of exceptional longevity, however, relevant studies have rarely extended to other fields of functioning. To date, little is known about what contributes to the experience of negative emotion in a very old population.ObjectiveWe aimed to provide a comprehensive key domain of functioning, including physical, cognitive, behavior, and negative emotion in older adults (OAs), followed by determination of predictors of negative emotion.MethodsData were collected from a nationally representative sample of 2570 Chinese OAs (aged 60 and above) from the 2014 wave of the Chinese Longitudinal Healthy Longevity Survey. Physical function was assessed using activities of daily living (ADL) and instrumental activities of daily living (IADL) measures. Cognitive function was assessed by the Modified Mini-Mental State Examination (mMMSE). Participants’ behavior included smoking, drinking, exercise, physical labor, and social activities. Negative emotion was assessed using four items on affective experiences to create an index of emotional well-being. The associations between various covariates and multiple health outcomes were examined using Pearson’s correlation. Multiple linear regressions were established to verify significant variables associated with respondents’ negative emotion.ResultsThe mean age was 80.20 years (SD=8.60). The mean ADL total score of the sample was 17.78 (SD=0.89), mean IADL total score was 21.93 (SD=3.69), the mean mMMSE total score was 21.63 (SD=2.23), the mean negative emotion total score was 8.89 (SD=2.64). Multiple linear regression analyses revealed that negative emotion was associated with self-perceived low economic status, poor self-rated health condition, poor sleep quality, low IADL function, less regular exercising, living in rural, and being female.ConclusionLimited physical functioning and social resources in rural residence may restrict the outpouring of emotion in OAs. Nevertheless, further intensive studies are warranted to provide guidance for the development of better living environment for this elderly population.
