Predictors and correlates of health-related quality of life and morbidity in overweight/obese adolescents: cohort study

现在，儿童肥胖流行病的规模和对健康的长期风险是毫无疑问的。然而，很少有研究在人口水平上审查其对心理健康和身体功能的直接影响，哪些途径会对这些后果产生风险和保护，以及它们可能对医疗保健产生的影响。这项研究将利用大约1500名维多利亚青少年的现有队列，从童年开始研究超重和肥胖的起源和影响的被忽视的方面。维多利亚青少年健康研究最初是在1997年进行的，当时孩子们正在读预科三年级。除了关于超重和肥胖的推定风险和保护因素以及身高和体重的直接测量的信息外，它的独特之处在于收集了自儿童在小学早期入学以来与健康有关的生活质量的数据。在第一波的八年后，孩子们将成为8-11年级的青少年。第三波将继续关注HRQoL。创新包括对儿童肥胖潜在的情绪、行为和身体后果的研究，这些后果可能反过来影响肥胖的自然史。这项以人口为基础的大型纵向研究将纠正2003年由NH和MRC特别确定的儿童和青少年超重肥胖的被忽视的方面。除了确定一系列常见问题是否与超重肥胖有关外，它还将能够揭示与青少年超重肥胖相关的不良后果的机制，并研究预测儿童期到青春期超重缓解的保护因素，这可能为预防活动提供信息。这项研究将为了解儿童和青少年超重肥胖的途径、患病率和预防机会做出国际贡献。

There is now no doubting the size and long-term risks to health of the childhood obesity epidemic. However, very little research has examined at population level its immediate consequences for mental health and physical functioning, what pathways confer risk and protection for these consequences, and their likely healthcare consequences. This study will utilise an existing cohort of approximately 1500 Victorian adolescents followed since childhood to examine neglected aspects of the genesis and impacts of overweight and obesity. The Health of Young Victorians Study was originally assembled in 1997 when the children were in Grades Prep-3. In addition to information on putative risk and protective factors for overweight-obesity and direct measures of height and weight, it is unique in having collected data on health-related quality of life (HRQoL) since children were first recruited during the early primary school years. Eight years after the first wave, the children will be adolescents in Grades 8-11. This third wave will retain a focus on HRQoL. Innovations include study of potential emotional, behavioural and physical consequences of childhood obesity that may in turn affect the natural history of obesity. This large, population-based longitudinal study will redress neglected aspects of child and adolescent overweight-obesity specifically identified in 2003 by the NH and MRC. As well as establishing whether a range of common problems are related to overweight-obesity, it will be able to shed light on mechanisms of adverse outcomes associated with adolescent overweight-obesity, and study protective factors predicting remitting overweight from childhood to adolescence that may inform preventive activities. The study will make an international contribution to knowledge about pathways, prevalence and preventive opportunities for child and adolescent overweight-obesity.
