QUALITY OF LIFE IN PATIENTS WITH ABDOMINAL OBESITY AFTER WEIGHT LOSS VIA DIET AND PHYSICAL EXERCISE
The purpose of the study: to examine and compare changing in quality of life in patients with abdominal obesity (AO) after weight loss via diet and combination of diet and physical exercise. Material and methods: 106 patients with AO (age 43,1±0,6 yrs, BMI - 32,5±0,4 kg/m2) were examined. The waist circumference (WC) was 99,1±1,3 cm in women and 108,3±1,1cm in men. Patients were randomized into 2 groups: 1) diet and 2) diet plus physical exercise (PE). Patients kept hypocaloric diet and performed daily moderate intensity physical training during 6 month. Before and after the trial were assessed: caloricity of dietary and fat intake according to patients’ diaries, anthropometric parameters, exercise performance through the cardiopulmo- nary exercise testing, and quality of life (QoL) measured by SF-36 health survey. The results of the study. Qual- ity of life signiﬁcantly increased in physical and mental well-being irrespective of the weight-loss methods (р=0,001, р=0,0001). Patients group 2 had better QoL at the vitality scale (68,5±2,5 and 60,3±2,5, р=0,009) and at the total physical component (52,1±1,1 and 48,7±1,4, р=0,03). The rate of BMI decrease had the most inﬂuence on the total physical component (r2=0,1, p=0,02), and the degree of decrease in WC- on total men- tal component (r2=0,09, p=0,03). When reducing caloric and fat intake QoL improve in physical and mental dimension (р=0,0001; р=0,01). Improvement of exercise tolerance increasing such QoL scales as: physical functioning (r=0,3, p=0,02), mental health (r=0,3, p=0,04), and vitality (r=0,3, p=0,02). Conclusion: When reducing body weight, the quality of life in patients with abdominal obesity improves and particularly due to combination of diet and physical exercise.
