Background
The increasing older adult population requires attention in terms of education and health, as higher education levels contribute to cognitive reserve and may protect against age-related cognitive impairment. Cognitive reserve is an individual’s cognitive flexibility in using cognitive functions affected by brain aging, neurological diseases, and injury. Indonesia has a high prevalence of low-educated older adults, which strongly correlates with progressive cognitive impairment. Identifying risk factors for cognitive decline in this population is crucial. This study determines the factors affecting cognitive impairment in low-educated older adults using cross-sectional data from the Indonesian Family Life Survey-5.
Methods
This descriptive study analyzed 2,313 low-educated older adults ≥60 years old. Univariate and bivariate analyses were used to describe the sample and identify the relationships between categorical variables. Logistic regression identified the most significant factor affecting cognitive impairment.
Results
The prevalence of cognitive impairment in low-educated older adults is 22.6%. The chi-square test revealed significant relationships between those who are aged 75 years, a status other than married, female, living in rural areas, and not participating in social activities. Age is the most prominent factor affecting cognitive impairment in such adults (P<0.001; adjusted odds ratio, 3.232; 95% confidence interval, 2.500–4.180).
Conclusion
Cognitive impairment in the aforementioned adults is associated with being ≥75 years old, being a status other than married, being female, living in rural areas, and not participating in social activities. After controlling other variables, low-educated older adults who participated in at least ≥1 social activity in the last 12 months experienced cognitive impairment 0.64 times compared to those who did not participate in social activities.
