The prevalence of chronic diseases among the participants was 69.0%. Nutritional status assessment revealed that 57.0% of the participants were overweight or obese based on BMI. Disability data indicated that 10.1% of the participants had hearing impairments, 63.9% had visual impairments, and 71.5% had oral health problems. Overall, 8.2% of the elderly had limitations in activities of daily living, and 19.6% experienced poor mental health.
