ENGLISH SUMMARY
Health-related quality of life during a clinical behavior weight loss intervention therapy
Hannesdottir SH, Gudmundsson L, Johannsson E
Introduction: The aim of this study was to assess the effect of a multidisciplinary, behavioural obesity treatment program on weight management, physical
improvements and health-related quality of life.
Material and methods: The participants counted 47 women aged 20-60 years. The measurement period was from October 2007-July 2009 and a median
time between measurements was six months. Measurements: height (cm), weight (kg), body mass index (BMI), waist circumference (WC), bioelectrical
impedance analysis (BIA), cycle ergometer fitness test (w/kg), electrocardiogram, maximal oxygen uptake (VOjmax), blood pressure (mmHg) and heart rate
(bpm). Different dimensions of mental and physical health were assessed using validated questionnaires: SF-36v2™of health-related quality of life, OP
scale of psychosocial functioning in the obese, BAI anxiety inventory scale and BDI-II depression inventory scale.
Results: BMI decreased on average by 3.9 kg/mJ (p<0.001). The total maximum output (watts) during the fitness test increased on average by 12%
(p<0.001), fitness (w/kg) increased by 21% (p<0.001) and V02max (ml/kg/min) by 18% (p<0.001). A decrease was noted in blood pressure as well as
resting heart rate (p<0.05) at the end of the program. The results from the questionnaires showed improvements in quality of life and psychological well
being (p<0.001).
Conclusion: These results highlight the importance of comprehensive weight management and emphasize the importance of permanent lifestyle changes
for the patients.
Keywords: Obesity, women, behavior therapy, ergometric.
