We examined changes in weight-specific health-related quality of life (HRQOL) and the relation to weight loss in a Serbian population undergoing diet-induced weight loss treatment. HRQOL was assessed at intake and after 1 year using the Impact of Weight on Quality of Life-Lite (IWQOL-Lite) questionnaire. Study sample consists of 135 obese patients. After 1 year of diet therapy, patients experienced an average weight loss of ~12%, and significant improvements were noted in all IWQOL-Lite domains (Physical Function, Self-esteem, Sexual Life, Public Distress and Work). Amount of weight loss was closely linked to all domains (F = 27.49; p < 0.001), except Sexual Life (F = 2.08; p = 0.108). In patients with weight reductions of 5%-9.99%, there was a great improvement in physical function and self-esteem. In those with ≥10% weight loss, there was improvement in all dimensions of IWQOL-Lite. With the prevalence of obesity rising worldwide, including in Serbia, the positive effects of weight loss on weight-specific HRQOL are encouraging.
我们研究了在接受饮食诱导体重减轻治疗的塞尔维亚人群中，体重特异性健康相关生活质量（HRQOL）的变化及其与体重减轻的关系。使用体重对生活质量的影响简化版（IWQOL-Lite）问卷在入组时和 1 年后评估 HRQOL。研究样本包括 135 名肥胖患者。经过 1 年的饮食治疗，患者的平均体重减轻约 12%，所有 IWQOL-Lite 领域（身体功能、自尊、性生活、公众困扰和工作）均有显著改善。体重减轻量与所有领域密切相关（F=27.49；p<0.001），除性生活领域（F=2.08；p=0.108）。在体重减轻 5%-9.99%的患者中，身体功能和自尊有很大改善。在体重减轻≥10%的患者中，IWQOL-Lite 的所有维度都有改善。随着肥胖症在全球范围内（包括塞尔维亚）的流行率上升，体重减轻对体重特异性 HRQOL 的积极影响令人鼓舞。
