Global Self-Esteem, Physical Activity, and Body Composition Changes Following a 12-Week Dietary and Physical Activity Intervention in Older Women

Older adults show lower physical activity. These changes altogether promote the development of overweight, obesity, and other chronic diseases. These factors substantially influence the quality of life and self-esteem of older adults. This phenomenon is especially visible after the lockdown caused by the COVID-19 pandemic. Objectives: Our study aimed to evaluate the effect of a 12-week reductive diet and a 12-week physical activity plan for older adults on the global self-esteem of lifestyle in 60–70-year-old women. Materials and methods: Our participants were 600 women with increased body mass (BMI > 25 kg/m(2)) aged 60–70 years. After the initial evaluation, the participants were randomly divided into three groups: CG—control group (n = 200); DI—dietary group (n = 200) that committed to a 12-week reductive diet; PA—physical activity group (n = 200) that committed to a 12-week physical activity plan. The global self-esteem score (using the SES Rosenberg scale) and the anthropometric measurements were collected before and after the 12-week study. In the statistical analysis of data, the significance level was assumed to be 0.05. Results: The global self-esteem score for all groups before the study started was 30–31 points, which corresponded to average self-esteem. After a 12-week dietary or physical activity intervention, the score in the DI group was 33, which corresponded with high self-esteem. In the CG group, the self-esteem score remained unchanged (30 points). The average body mass loss was 0.5 kg/m(2) for CG, 1.92 kg/m(2) for DI, and 1.10 kg/m(2) for the PA group. The average waist–hip ratio (WHR) change for CG, DI, and PA was 1 cm, 1 cm, and 2 cm, respectively. A decrease in body mass and body composition indicators (BMI and WHR) corresponded to participants’ global self-esteem increase (p < 0.05); the greater the decrease noted for BMI and WHR, the greater the global self-esteem score that was achieved. In the CG group, a negative correlation between global self-esteem and BMI value (p < 0.05) was observed. Conclusions: A 12-week reductive diet and a 12-week regular physical activity plan lowered participants’ body mass. Adipose tissue content was reflected by decreased BMI and WHR indicators of participants from the DI and PA groups and was accompanied by higher global self-esteem scores.
