Obesity is a global burden that impairs an individual's Quality of life (QOL) psychologically, economically, physiologically, and socially. Nevertheless, QOL is a multi-dimensional term with no standard definition. Health related QOL (HRQOL) can be defined as" individual perception about social, physical, mental aspects of health, and how health affects the ability to function in life ". Many studies have addressed the negative association between excess weight and HRQOL. This study aimed to assess HRQOL and to assess the effect of weight loss among overweight/obese adults after attending short-term weight management programs on HRQOL and changes in HRQOL. Participants were recruited from adults referred to Nutri Health centers of(Ramallah, Nablus, Jenin, Hebron and Tulkarm) for weight management programs during the period between 1of May 2019 to 30 November 2020. A total of 466 participants (81 males and 383 females) with a BMI(body mass index) more than 25kg /m² were involved in the study. Body composition, anthropometric measurements, socio-demographic data, and HRQOL were determined at baseline and after 3 months of follow-up weight-management program. The results showed a significant decline in the mean weight of participants from93.9±17.2Kg to83.9±15.7 kg over three months; however, (48.7%) participants reported a reduction of less than 10% of their weight while (51.3%) participants had a reduction of more than 10% of their weight over 3 months. By using paired sample T-test participants reported significant improvement in all components of (36-SF) HRQOL after 3 months compared to baseline scores. At baseline, participants with higher BMI significantly reported lower scores in HRQOL subscales of Physical functioning, Pain, Vitality, and General health. while after 3 months, participants with ≥10% loss of baseline weight had a greater improvement in the overall QOL scores by 14.6±17.6 (mean ± SD) compared to 9.7±15.0 for those who lost <10% baseline body weight. Moreover, the Role limitation due to physical health achieved the highest score after 3 months with mean ±SD of 93.0±20.7 compared to baseline score of 80.8±32.2. The highest improvement was reported in Physical functioning with 18.9 ± 27.3 and 10.9 ± 27.3 for participants lost ≥ 10% and < 10%, respectively. In conclusion, weight management programs seemed to be not only effective to induce weight loss but also, to improve HRQOL. Excess weight is considered a detrimental factor for HRQOL. Moreover, data have shown that overweight/obese women were more likely to have poorer HRQOL at baseline with less improvement in HRQOL after 3 months compared to men. Finally, the findings of this study have confirmed that the weight management is a holistic process that should consider the patients views and improvement in QOL after weight reduction.
