Social activity of patients with sarcopenic obesity and age-related pathology of the organ of vision

Introduction. Sarcopenic obesity and visual impairment increase the risk of developing certain functional deficits and reducing social activity in everyday life. However, social activity has been virtually ignored in the elderly population with age-related macular degeneration and sarcopenic obesity.

The purpose of the research is to assessment of social activity of patients with sarcopenic obesity and age-associated pathology of the organ of vision.

Materials and methods. To perform this study, two clinical groups were randomly selected, one of which consisted of one hundred thirty four patients with age-related macular degeneration and sarcopenic obesity. The control group consisted of 132 patients with sarcopenic obesity only. Determination of the body mass index and hand dynamometry were used to identify sarcopenic obesity. Social activity in everyday life was determined using the Lawton scale.

Results. The decrease in social activity in the compared groups is mainly due to difficulties in using transport — 0.52 ± 0.07 points with a combination of age-related macular degeneration and sarcopenic obesity compared to 0.78 ± 0.6 points (p < 0.01) in the control group. Making purchases — 0.62 ± 0.06 and 0.76 ± 0.08 points (p < 0.01) performing financial activities — 0.48 ± 0.05 and 0.61 ± 0.04 points (p < 0.001), respectively. In addition, sarcopenic obesity and age-related macular degeneration cause a statistically significant decrease in all types of social activity in everyday life with the exception of maintaining house (apartment) — 0.70 ± 0.06 points versus 0.73 ± 0.07 points (p > 0.05).

Research limitations. Study of social activity of elderly patients without comparison with other age groups.

Conclusion. The decline in social activity in elderly patients with age-related macular degeneration and sarcopenic obesity is more significant than with the impact of sarcopenic obesity alone. At the same time, the deterioration in social activity among patients with sarcopenic obesity and age-related macular degeneration occurs especially pronounced in the use of transport, making phone calls, shopping and conducting financial transactions.
