Utilizing current information to project prospective ill health prevalence can help prepare the country to ensure the well-being of older people. The prevalence of ill health in terms of physical, psychological, and cognitive health dimensions was estimated by age, sex, and education attainment level using the 2018 Longitudinal Study on Aging and Health in the Philippines. Subsequently, the said rates were integrated into population projection estimates from 2020 to 2080. It was observed that the depression prevalence rate among older people was highest at above 40%, while physical and cognitive limitations were at around 18% and 22% respectively. It was also found that prevalence rates of ill health increased with age and that ill health was more prevalent among women than men, particularly at more advanced ages. The use of population projections has shown that education differentials in the analyses estimate lower prevalence rates of ill health for both sexes. The findings provide estimates for the prospective care needs of the older population in the Philippines. It was also suggested that education may possibly have preventive effects on ill health. Utilizing present information in order to prepare for issues can be beneficial for securing the well-being of older adults.
