Quality of life and its associated factors among older persons in Malaysia

Abstract

Aim Quality of life (QoL) among the older persons provides valuable insights into the potential modifiable risk factors that affect well‐being in later life. This study aimed to describe the QoL and psychosocial factors of QoL of older persons in Malaysia. Methods We used the 19‐item Control, Autonomy, Self‐realization and Pleasure scale, a validated instrument that measures psychological well‐being related to QoL in older persons. Scores range from 0 to 57, and higher scores indicate better QoL. We included several factors as covariates. Analysis of complex samples was carried out using Stata 15. Descriptive analysis was carried out to determine QoL by sociodemographic characteristics and other factors. Linear regression analysis was used to identify psychosocial factors that influence QoL. Results A total of 3444 individuals aged ≥60 years completed all 19‐item Control, Autonomy, Self‐realization and Pleasure items. The estimated mean QoL score was 47.01 (95% CI 46.30–47.72). Adjusted for confounders, QoL was lower among individuals with no formal education (−2.554, 95% CI −3.684, −1.424), probable depression (−1.042, 95% CI −1.212, −0.871) and food insecurity (−0.815, 95% CI −1.083, −0.548). QoL continued to improve with improved ADL score (0.302, 95% CI 0.052, 0.552), IADL score (0.646, 95% CI 0.382, 0.909) and better social support (0.308, 95% CI 0.187, 0.429). Conclusions Lower education, depression, food insecurity, presence of limited functional status and poor social support negatively influenced QoL in older Malaysians. This study identified potentially modifiable factors that could be targeted for interventions to enhance QoL of older persons in Malaysia. Geriatr Gerontol Int 2020; 20: 92–97.
