DESCRIPTION (provided by applicant): We propose a longitudinal population-based study to identify modifiable factors associated with becoming overweight or obese. We will provide new evidence on the factors associated with the maintenance of stable weight and body mass index (BMI) in adults. Further, we will examine the dynamic relationships among physical activity, weight, health-related quality of life (HRQL), and the physical and social environment. Data come from a major longitudinal population health survey, the Canadian National Population Health Survey (NPHS), for the period 1994/95-2006/07. Analyses will exploit data on a cohort of 13,045 adults (18+) interviewed in 1996/97 and every two years thereafter, with follow-up data through 2006-07. Analyses will be conducted using a determinants of population-health framework in which demographic factors, number of chronic health conditions, health behaviors, psychological health, psychological resources, social resource and other variables known to be associated with health are included. Further, in this framework, we will investigate the importance of the physical and social environment in explaining the trends in weight and BMI. Analyses will be conducted separately for men and women. The research will be conducted by a multi- disciplinary team of investigators. There are two primary aims for the exploratory two-year project. Aim #1. In a longitudinal cohort of 13,045 adults, we will investigate the factors that predict the maintenance of stable weight, weight gain, and weight loss over a 10-year follow-up period. We will also investigate the factors that predict change (or lack thereof) in BMI category (underweight, normal, overweight, and obese). Aim #2. We will investigate the relationships among physical activity, BMI, the built environment, the social environment, and HRQL. In particular, we will examine the temporal relationships between changes in physical activity and changes in BMI and HRQL. PUBLIC HEALTH RELEVANCE: Obesity is a health risk. Little is known about the patterns of change in physical activity, weight, and health- related quality of life over time. Findings from this study will identify modifiable risk factors for obesity and overweight.

描述（由申请人提供）：我们提出一项基于人群的纵向研究，以确定与超重或肥胖相关的可改变因素。我们将提供与成人维持稳定体重和体重指数（BMI）相关的因素的新证据。此外，我们将研究身体活动、体重、健康相关生活质量 (HRQL) 以及身体和社会环境之间的动态关系。数据来自一项主要的纵向人口健康调查，即 1994/95 年至 2006/07 年期间的加拿大国家人口健康调查 (NPHS)。分析将利用 1996/97 年以及此后每两年接受采访的 13,045 名成年人（18 岁以上）的数据，以及 2006-07 年的后续数据。将使用人口健康决定因素框架进行分析，其中包括人口因素、慢性健康状况的数量、健康行为、心理健康、心理资源、社会资源和其他已知与健康相关的变量。此外，在此框架中，我们将研究物理和社会环境在解释体重和体重指数趋势方面的重要性。分析将分别针对男性和女性进行。该研究将由多学科研究人员团队进行。这个为期两年的探索性项目有两个主要目标。目标#1。在 13,045 名成年人的纵向队列中，我们将研究预测 10 年随访期间体重稳定、体重增加和体重减轻的预测因素。我们还将研究预测 BMI 类别（体重不足、正常、超重和肥胖）变化（或缺乏变化）的因素。目标#2。我们将研究身体活动、BMI、建筑环境、社会环境和 HRQL 之间的关系。特别是，我们将检查体力活动变化与 BMI 和 HRQL 变化之间的时间关系。公共卫生相关性：肥胖是一种健康风险。人们对身体活动、体重和健康相关生活质量随时间的变化模式知之甚少。这项研究的结果将确定肥胖和超重的可改变危险因素。
