Quality of Life in Elders with Suspected Alzheimer Disease: An Urban Health Centers-Based Study from Iran

BACKGROUND/AIMS: Quality of life (QOL) and Alzheimer disease (AD) among older people have been recognized as public health challenges. Here, we investigated the association between QOL and AD in the elders. METHODS: In this cross-sectional study, elderly people were selected from urban health centers (Shiraz, Iran) by multistage cluster random sampling and were interviewed using LEIPAD (for QOL) and Montreal Cognitive Assessment (for AD) questionnaires. The data was analyzed using Mplus (version 6.12) and IBM SPSS (version 25) software. RESULTS: The participants consisted of 182 elderly with a mean age of 67 ± 5.05 years, and 95 (52.2%) of them were females. There were 161 (88.5%) and 130 (71.4%) cases educated up to 12 years and married, respectively. Furthermore, 46 (25.3%) had low-to-moderate QOL, and 132 (72.5%) were suspected to have AD. QOL was inversely associated with AD, and men (β = −0.310) were more affected than women (β = −0.290). AD (β = −0.298), age (β = −0.288), hypertension (β = −0.267), education (β = 0.260), and body mass index (β = −0.198) were determinants of QOL. Also, physical activity was indirectly associated with QOL (β = 0.076). AD was correlated with the cognitive functioning component of QOL (r = −0.72). CONCLUSION: One elder out of 4, did not have desirable QOL and 3 elders out of 4 were suspected to have AD. AD can decrease QOL among the older people. Screening of the elders for AD is recommended to improve their QOL by health centers.
