Evidence suggests an inverse relationship between excess weight and health-related quality of life (HRQoL) in children and adolescents, however little is known about whether this association is moderated by variables such as gender and age. This study aimed to investigate these relationships.
Participants were secondary school students (818 females, 52% and 765 males, 48%) from 23 secondary schools in Victoria, Australia. Age ranged from 11.0 to 19.6 years (mean age 14.5 years). The adolescent version of the Assessment of Quality of Life (AQoL) Instrument (AQoL-6D) which is a self-reported measure of adolescent quality of life was administered and anthropometric measures (height and weight) were taken. Assessment of weight status was categorized using the Body Mass Index (BMI).
HRQoL was associated with gender and age, but not weight status or socio-economic status; with males and younger adolescents having higher HRQoL scores than their female and older adolescent counterparts (both p < 0.05). There was also a significant interaction of weight status by gender whereby overweight females had poorer HRQoL (-.06 units) relative to healthy weight females (p < 0.05).
This study contributes to the evidence base around factors associated with adolescent HRQoL and reveals that gender and age are important correlates of HRQoL in an Australian adolescent population. This knowledge is critical to inform the design of health promotion initiatives so they can be tailored to be gender- and age-specific.

有证据表明，儿童和青少年的超重与健康相关生活质量（HRQoL）之间存在负相关关系，然而，对于这种关联是否受到性别和年龄等变量的调节，人们知之甚少。本研究旨在调查这些关系。
参与者为来自澳大利亚维多利亚州23所中学的中学生（818名女生，占52%；765名男生，占48%）。年龄范围为11.0至19.6岁（平均年龄14.5岁）。使用青少年生活质量评估工具（AQoL）的青少年版（AQoL-6D）进行自我报告的青少年生活质量测量，并进行人体测量（身高和体重）。使用体重指数（BMI）对体重状况进行分类评估。
HRQoL与性别和年龄相关，但与体重状况或社会经济地位无关；男性和较年轻的青少年的HRQoL得分高于女性和年龄较大的青少年（均p<0.05）。体重状况和性别之间也存在显著的交互作用，超重女性的HRQoL（-0.06单位）相对于健康体重女性较差（p<0.05）。
本研究为围绕青少年HRQoL相关因素的证据库做出了贡献，并揭示了性别和年龄是澳大利亚青少年人群中HRQoL的重要相关因素。这些知识对于健康促进举措的设计至关重要，以便能够针对性别和年龄进行量身定制。
