BACKGROUND Obesity can develop during any life stage. Understanding the contexts within which obesity develops can inform our understanding of the disease and help tailor interventions specific to life stages. OBJECTIVE Using life-course theory as a guiding framework, this study aimed to explain the development of obesity in bariatric surgery patients by creating personalized weight trajectories. DESIGN Qualitative methods using semistructured interviews were used to uncover participants' experiences with and explanations for the development of obesity. A grounded theory approach using the constant comparative method was used to analyze transcripts for categories and themes. PARTICIPANTS/SETTING Thirty pre-bariatric surgery patients (24 women, 6 men) were recruited from a bariatric surgery center; 25 participants were available for follow-up. Participants were interviewed before surgery and at 6 and 12 months postsurgery. RESULTS Four weight history groups were created based on patterns of weight changes from adolescence through adulthood: Always Heavy, Late Peak, Steady Progression, and Weight Cycling. Participants' explanations for weight changes centered around themes of transitions and life-course events or stressors. Differences in the weight history groups could be explained by the timing of transitions, life events, and responses to stress. CONCLUSIONS The development of obesity does not follow the same pattern for all individuals. Weight gain patterns can be explained by the timing of life-course events, stressors, and the type and effects of environmental transitions. Weight management counseling should include strategies tailored to an individual's current life-stage and circumstance, but also acknowledge previous responses to transitions and stressors.

“带我了解你的体重历史”：使用定性访谈创建个性化的体重轨迹，了解准备减肥手术的患者肥胖的发展

背景肥胖可以在生命的任何阶段发展。了解肥胖发展的背景可以帮助我们了解这种疾病，并有助于定制针对特定生命阶段的干预措施。目的 以生命历程理论为指导框架，本研究旨在通过创建个性化的体重轨迹来解释减肥手术患者肥胖的发展。设计 使用半结构化访谈的定性方法来揭示参与者对肥胖发展的经历和解释。使用恒定比较方法的扎根理论方法用于分析类别和主题的成绩单。参与者/设置 从减肥手术中心招募了 30 名减肥手术前患者（24 名女性，6 名男性）；有 25 名参与者可进行随访。参与者在手术前以及术后 6 个月和 12 个月接受了采访。结果 根据从青春期到成年期的体重变化模式，创建了四个体重历史组：始终沉重、高峰晚期、稳定进展和体重循环。参与者对体重变化的解释以过渡和生命历程事件或压力源为主题。体重历史组的差异可以通过转变的时间、生活事件和对压力的反应来解释。结论 肥胖的发展并非所有个体都遵循相同的模式。体重增加模式可以通过生命历程事件发生的时间、压力源以及环境转变的类型和影响来解释。体重管理咨询应包括为个人量身定制的策略
