Determinants of Health-Related Quality of Life Among Community-Dwelling Thai Older Adults in Chiang Mai, Northern Thailand

Abstract

Background Population aging has been growing worldwide and Thailand has become an aged society with 20% of its population aged 60 and over. Age-related decline in physical and mental health impacts the health-related quality of life (HRQOL) of older adults. Purpose We aimed to describe the HRQOL of Thai older adults, residing in the community. Methods This cross-sectional survey was part of a Community-Integrated Intermediary Care project (CIIC), TCTR20190412004. A total of 1509 participants from an intervention arm of a cluster randomized controlled trial were included. A Thai version of the Euro-Qol questionnaire (EQ-5D-5L) was used to determine the HRQOL and associated sociodemographic background, health behaviors and underlying diseases of a representative sample from Maehia, Chiang Mai, Thailand. SPSS version 24 was used to analyze data via descriptive analysis and binary logistic regression. Results The mean age of the participants was 69.31±7.10 years, and nearly a quarter (23.8%) was older than 75 years. The mean EQ index score was 0.81±0.23 and older age, lower educational attainment, unemployment, lack of exercise habits, current smokers, having history of a fall in the last 6 months, diabetes, hyperlipidemia, dependency assessed using Barthel’s Activity of Daily Living (ADL) Index, and depression using the Geriatric Depression Scale (GDS) were more likely to represent HRQOL-related problems. Conclusion Our findings have highlighted the factors affecting the HRQOL of community-dwelling older adults which could be of importance in preparing for active and healthy aging communities. The routine dependency assessment using the ADL index will be useful in estimating the HRQOL of the aging population. Fall prevention programs are also recommended to reduce dependency. Moreover, the association of having diabetes and hyperlipidemia with problems in HRQOL dimensions highlight the need for public health intervention not only to prevent the increasing burden of non-communicable diseases but also to improve the HRQOL of older adults.

Tooth Loss, Cognitive Impairment and Fall Risk: A Cross-Sectional Study of Older Adults in Rural Thailand

“…The investigators involved in the assessment were blinded to the random sampling process. The ADLs were evaluated using Barthel’s ADL index with a Cronbach’s alpha reliability coefficient of 0.90 [ 16 ]. The evaluation form had ten items on the ADL checklist on bathing, dressing, bowel and bladder care, feeding, grooming, climbing stairs, ambulation, transfer, and toilet use.…”

Factors related to quality of life in community-dwelling adults in Sleman Regency, Special Region of Yogyakarta, Indonesia: Results from a cross-sectional study

“…In addition to other issues, such as the increasing prevalence of chronic diseases across all ages, shrinking family sizes [ 10 ] and limited access to mental health care [ 15 ], older adults in Indonesia may experience considerable challenges in maintaining their QoL. Previous studies in Indonesia [ 16 , 17 ] and Southeast Asia [ 18 , 19 ] have identified that sociodemographic, physical, and psychological factors may influence QoL among older adults; however, these studies did not explore the influence of these determinants on QoL aspects. Exploration of the association between the determinants and QoL aspects is important to describe the dynamics of QoL and its related factors, and thus may provide recommendations for various disciplines.…”
