To determine whether the health-related quality of life (HRQOL) of overweight and obese adolescents is significantly lower than that of their healthy weight counterparts, and if so, whether any demographic trends exist and the relative contribution of each HRQOL dimension.
Cross-sectional analysis of 2,890 students participating in the Pacific Obesity Prevention in Communities Project, Australia. HRQOL was measured using the Pediatric Quality of Life Inventory (PedsQL) adolescent module. Adolescent height and weight were measured by trained field workers and weight categories assigned according to the International Obesity Task Force BMI cut-off points for adolescents. Multivariate linear regression analyses were undertaken to estimate the mean differences in HRQOL scores between (i) overweight and healthy weight, and (ii) obese and healthy weight adolescents, whilst adjusting for gender, age and socioeconomic status quartile.
The sample had a mean age of 14.6 years (range 11-18), 56.2% boys, 20.2% overweight and 6.3% obese. Higher weight status categories were associated with lower HRQOL scores (mean PedsQL scores: healthy weight: 79.1, overweight: 77.7 and obese: 73.7). Relative to the healthy weight group, and after adjustments, overweight and obese adolescents reported 1.44 (p = 0.005) and 5.55 (p < 0.001) lower HRQOL summary scores, respectively. Overweight adolescents reported significantly lower scores in physical and social functioning, whilst obese adolescents reported significantly lower scores in the same dimensions plus emotional functioning. Girls and younger (< 15 years) adolescents reported greater mean negative HRQOL differences associated with excess weight.
Overweight and obesity in adolescents are associated with significantly lower HRQOL scores.
确定超重和肥胖青少年的健康相关生活质量（HRQOL）是否显著低于体重正常的同龄人；若如此，是否存在任何人口统计学趋势以及各HRQOL维度的相对贡献情况。
对参与澳大利亚社区预防肥胖项目的2890名学生进行横断面分析。使用儿童生活质量量表（PedsQL）青少年模块来测量HRQOL。由经过培训的现场工作人员测量青少年的身高和体重，并根据国际肥胖特别工作组针对青少年的BMI切点划分体重类别。进行多变量线性回归分析，以估计（i）超重与体重正常以及（ii）肥胖与体重正常青少年之间HRQOL得分的平均差异，同时对性别、年龄和社会经济地位四分位数进行调整。
样本的平均年龄为14.6岁（范围11 - 18岁），男孩占56.2%，超重者占20.2%，肥胖者占6.3%。较高的体重状态类别与较低的HRQOL得分相关（PedsQL平均得分：体重正常：79.1，超重：77.7，肥胖：73.7）。相对于体重正常组，调整后超重和肥胖青少年的HRQOL综合得分分别低1.44（p = 0.005）和5.55（p < 0.001）。超重青少年在身体和社会功能方面的得分显著较低，而肥胖青少年在相同维度以及情绪功能方面的得分显著较低。女孩和年龄较小（< 15岁）的青少年报告与超重相关的平均HRQOL负差异更大。
青少年超重和肥胖与显著较低的HRQOL得分相关。
