Background: The Population Census 2011 reveals that there are nearly 104 million elderly persons (aged 60 years or above) in India. A report by UNFPA India estimates that the number of elderly persons is expected to grow to 173 million by 2026. The rapid advancement in technology had taken medical science to higher realms of offering better health care services as well as increased longevity to the population. Combining along with reduced birth rate, the elderly population has considerably increased. A supportive family and environment promotes health and sustains a better quality of life of elderly. Interventions promoting quality of life of older adults reduces the burden of care of them in the society. Objective of the study was to assess the effect of health promotion interventions on QoL among older adults. Method: Quantitative approach with pre experimental design was used to assess the effect of health promotion interventions on QoL among 30 older adults of a selected old age home, Thrissur, Kerala. After assessing the demographic variables of the study participants the modified WHO BREF scale was administered to assess their QoL. Posttest using the same tool was administered after seven days of the intervention which included brisk walking, stretching exercises and laughter therapy. Results: Data was tabulated and analyzed using differential and inferential statistics. The findings revealed that there is a significant difference between pre and post interventional mean score especially in three domains – physical, (54.53 and 73.90) psychological health (58.9 and 72.7) & social relationship (64.33 and 76.33) respectively. Whereas there was no significant difference in pre and post interventional score in the fourth domain. Conclusion: The study highlights that health promotion intervention if provided with regular health care services of elderly helps to sustain them with better quality of life with productivity within their limits.
