Obesity not only increases risk for morbidity/mortality, but also impacts the quality of life of obese individuals. In the United States, black women have the highest prevalence of obesity of any other group with approximately 80% of black women over age 20 having a body mass index (BMI) ≥25 kg/m. We aimed to examine the association between BMI and quality of life in this high risk population compared to this association in white women, using the Impact of Weight on Quality of Life (IWQOL)-Lite questionnaire. Data from 172 black women (mean BMI= 35.7; age=40.5) and 171 white women (mean BMI= 35.5; age=40.4) were collected between 2000 and 2010 analyzed in 2010. The mean IWQOL-Lite total score was 81.6 for black women compared to 66.9 for white women, a statistically significant difference. Hierarchical linear regression models revealed a significant BMI-by-race interaction indicating that the relationship between BMI and IWQOL-Lite score was moderated by race. Our findings suggest notable differences in weight-related quality of life in black and white women. At similar BMIs, black women consistently reported better quality of life than white women on all IWQOL-Lite subscales. The greatest difference in IWQOL-Lite scores between black and white women was seen in the self-esteem subscale. Additional research is needed to understand how to incorporate the weight perspectives of black women into weight management messages and interventions.
肥胖不仅会增加发病/死亡风险，还会影响肥胖个体的生活质量。在美国，黑人女性的肥胖患病率高于其他任何群体，20岁以上的黑人女性中约80%的体重指数（BMI）≥25kg/m²。我们旨在使用体重对生活质量的影响（IWQOL）-精简版问卷，研究该高危人群中BMI与生活质量之间的关联，并与白人女性中的这种关联进行比较。收集了2000年至2010年间172名黑人女性（平均BMI = 35.7；年龄 = 40.5岁）和171名白人女性（平均BMI = 35.5；年龄 = 40.4岁）的数据，并于2010年进行分析。黑人女性的IWQOL-精简版总分平均为81.6分，而白人女性为66.9分，差异具有统计学意义。分层线性回归模型显示BMI与种族之间存在显著的交互作用，表明BMI与IWQOL-精简版得分之间的关系受种族影响。我们的研究结果表明，黑人和白人女性在与体重相关的生活质量方面存在显著差异。在相似的BMI水平下，黑人女性在所有IWQOL-精简版子量表上的生活质量报告始终优于白人女性。黑人和白人女性在IWQOL-精简版得分上的最大差异出现在自尊子量表上。需要进一步研究，以了解如何将黑人女性的体重观念纳入体重管理信息和干预措施中。
