To describe the factors that motivate emerging adults to engage in weight-related self-monitoring (WRSM) and to determine the age of initiating WRSM.
Mixed-methods cross-sectional study, including quantitative survey and semi-structured interviews.
Tracking-EAT participants came from the population-based sample of Project EAT (Eating and Activity over Time); 138 participants (mean age=26.5 years; range 22-29) completed a survey, 25 of which also completed a semi-structured interview.
Internal and external motivations for WRSM and the age when participants began WRSM were assessed quantitatively. Semi-structured interviews assessed how participants were introduced to and why they used WRSM.
Descriptive statistics for quantitative measures. Inductive thematic analysis for qualitative analyses.
Participants reported internal (e.g., trying to lose weight, change body shape), external (e.g., advice from health professionals, friends/or family), and social/environmental motivations (e.g., WRSM being ubiquitous in our culture). A sense of moral obligation to strive for health contributed to participants' motivation to engage in WRSM. Participants reported self-monitoring dietary intake and weight as young as 8 years old and exercise as young as 9 years old.
Numerous factors converge to normalize and encourage WRSM, including internal, external, and social/environmental motivations. Future research could explore how the age of introduction and motivation for use affect the health impacts of WRSM.
描述促使青少年参与体重相关自我监测(WRSM)的因素,并确定开始进行WRSM的年龄。
混合方法横断面研究,包括定量调查和半结构化访谈。
追踪饮食研究的参与者来自“随时间推移的饮食与活动”(Project EAT)基于人群的样本;138名参与者(平均年龄 = 26.5岁;范围22 - 29岁)完成了一项调查,其中25人还完成了半结构化访谈。
对WRSM的内部和外部动机以及参与者开始进行WRSM的年龄进行定量评估。半结构化访谈评估参与者是如何接触到以及为何使用WRSM的。
对定量测量进行描述性统计。对定性分析进行归纳主题分析。
参与者报告了内部动机(例如,试图减肥、改变体型)、外部动机(例如,健康专业人员、朋友/家人的建议)以及社会/环境动机(例如,WRSM在我们的文化中无处不在)。追求健康的道德责任感促使参与者有动机参与WRSM。参与者报告早在8岁就开始自我监测饮食摄入量和体重,9岁开始自我监测运动。
包括内部、外部以及社会/环境动机在内的众多因素共同作用,使WRSM常态化并得到鼓励。未来的研究可以探索引入WRSM的年龄和使用动机如何影响WRSM对健康的影响。
