Abstract
Objective: Elderly with a low socioeconomic status (SES) face multiple health problems due to unhealthy lifestyle characteristics. Consequently, a multifactorial lifestyle changing intervention was implemented in sedentary elderly {65+) with a low SES. This study focuses on the response of sedentary elderly with a low SES to the multifactorial intervention program, the effects of this intervention on physical activity and physical fitness and the psychosocial determinants of physical activity and physical fitness. Methods: A pre-experimental design was used in a sample of 38 elderly (mean age: 73.6 ± 5.3 years) with a low SES (92% low income and/or low education), who were recruited with a personal approach strategy. Physical activity (steps/day) and physical fitness (leg/handgrip strength, endurance) measurements were taken before and after a 16 week, once a week multifactorial lifestyle changing intervention in elderly. Depressive symptoms, loneliness, and resilience were assessed on baseline. To test whether subjects improved on physical activity and physical fitness, a paired sample t-test was performed for steps/day, leg/handgrip strength, and endurance. A multiple regression analysis (method enter) was used to evaluate the impact of depression, loneliness and resilience on the change of physical activity and leg strength. In addition, the increase of physical activity (steps/day) was added in the multiple regression for leg strength. Results: One out of five sedentary elderly applied to the program. The number of steps per day increased with 23% after the intervention (t=-2.8(14), p=.01). Leg strength improved significantly with 13% (t=-3.9{37), p<.001). Results show a proportion explained variance of R2=.35 for physical activity by depressive symptoms, loneliness and resilience and R2=.24 for leg strength by physical activity, and the psychosocial determinants. None of the predictors contributed significantly to the explanation of variance in both physical activity and leg strength. Conclusions: The first results of the DELFGOUD program show a multifactorial intervention is successful in the recruitment and enhancement of physical activity (steps/day) and leg strength in elderly with a low SES.
