Knowledge and practice regarding hypertension and diabetes among the elderly in a rural area in southern India following an educational program: A comparative study

Abstract

Aim: Hypertension and diabetes mellitus are important problems in the elderly. They can largely be avoided through appropriate lifestyle modification. We implemented an ongoing education program for the elderly in the villages near Bangalore, Southern Karnataka, India. This study aimed to assess the knowledge and practice regarding hypertension and diabetes among elderly residents in the study area with and without exposure to the education program. Materials and Methods: Elderly residents of three villages who attended the educational sessions (exposed) and two similar villages without educational exposure (unexposed) were identified, matched with regard to age and gender, and interviewed to assess the knowledge and practice regarding hypertension and diabetes. The responses were scored, and mean scores were calculated in the two groups. Results and Discussion: A total of 130 elderly persons, 65 exposed and 65 unexposed to the education program were interviewed. Overall, the exposed group scored significantly higher than the unexposed group with respect to knowledge (11.17 vs 4.97, P < 0.05) and practice (1.35 vs 0.40, P < 0.05) regarding hypertension. Knowledge (14.85 vs 6.57, P < 0.05) and practice (1.49 vs 0.34, P < 0.05) scores regarding diabetes were also higher in the exposed group. However, the scores were less than 50% of the maximum attainable score even in the exposed group showing the need for further educational input. Conclusion: Regular health education sessions by physicians, nurses, and community health workers for the elderly are a useful strategy in improving the knowledge and practice for preventing and managing chronic disease. This is a model of health promotion in the elderly.
