Abstract

Background

Research suggests underestimation of body weight may be associated with beneficial psychological resilience against consequences of obesity, compared with accurate perception. Less is known about the comparison between those who underestimate versus those who overestimate their body weight.

Objective

To investigate differences in life satisfaction, social/emotional support, and weight change intentions between those who underestimate vs overestimate vs accurately perceive their body weight.

Study Design, Settings, Participants

Data were collected between 2008-2023 from the College Health and Nutrition Assessment Survey, a cross-sectional study of undergraduates, ages 18-24 years. After exclusions for missing data, the final sample (n=8203) was 93.9% white, 69.3% female, and had a mean age of 18.9±1.1.

Measurable Outcome/Analysis

Weight self-perception, weight change intent, life satisfaction, and social/emotional support, were measured via online survey. BMI (kg/m2) was calculated via height and weight measured by technicians, then compared with weight self-perception to determine self-perception accuracy. Chi-square analysis was used to evaluate differences between self-perception accuracy categories.

Results

About two-thirds (68.9%) perceived their weight category accurately, while one-third (31.1%) misperceived, with 19.5% underestimating and 11.6% overestimating. Women were more likely to overestimate (14.7% vs. 4.6%, p<.001), while men were more likely to underestimate their weight (37.5% vs. 11.6%, p<.001). Underestimaters were more likely to report weight maintenance intent or no weight change intent vs. overestimaters (33.2% vs. 14.2%, p<.001). Overestimaters were less likely to report high life satisfaction compared with underestimators and accurate perceivers (19.9% vs. 35.8% vs. 33.4%, p<.001). No differences in self-reported social support between groups were observed.

Conclusions

In young adults, data suggest underestimation of weight was associated with less intentional weight change behavior and higher life satisfaction. These results may help guide practitioners working with young adults by revealing differing patterns in weight misperception.

心理复原力的衡量标准会随自我感觉的体重状况而变化吗?
背景研究表明,与准确感知体重相比,低估体重可能与对肥胖后果的有益心理复原力有关。研究设计、环境、参与者数据收集于 2008-2023 年间的大学生健康与营养评估调查,这是一项针对 18-24 岁大学生的横断面研究。在排除缺失数据后,最终样本(n=8203)中白人占 93.9%,女性占 69.3%,平均年龄为(18.9±1.1)岁。可测量结果/分析体重自我认知、体重改变意愿、生活满意度和社会/情感支持通过在线调查进行测量。体重指数(kg/m2)通过技术人员测量的身高和体重计算得出,然后与体重自我感觉进行比较,以确定自我感觉的准确性。结果 约有三分之二(68.9%)的人准确地感知了自己的体重类别,三分之一(31.1%)的人感知错误,其中19.5%的人低估了自己的体重,11.6%的人高估了自己的体重。女性更容易高估自己的体重(14.7% 对 4.6%,p< .001),而男性更容易低估自己的体重(37.5% 对 11.6%,p< .001)。与高估者相比,低估者更有可能报告体重维持意愿或无体重变化意愿(33.2% 对 14.2%,p< .001)。与低估者和准确感知者相比,高估者较少报告生活满意度高(19.9% vs. 35.8% vs. 33.4%,p<.001)。结论在年轻人中,数据表明低估体重与较少的有意改变体重行为和较高的生活满意度有关。通过揭示体重错误认知的不同模式,这些结果可能有助于指导从业人员与青壮年开展合作。

期刊介绍: The Journal of Nutrition Education and Behavior (JNEB), the official journal of the Society for Nutrition Education and Behavior, is a refereed, scientific periodical that serves as a global resource for all professionals with an interest in nutrition education; nutrition and physical activity behavior theories and intervention outcomes; complementary and alternative medicine related to nutrition behaviors; food environment; food, nutrition, and physical activity communication strategies including technology; nutrition-related economics; food safety education; and scholarship of learning related to these areas. The purpose of JNEB is to document and disseminate original research and emerging issues and practices relevant to these areas worldwide. The Journal of Nutrition Education and Behavior welcomes evidence-based manuscripts that provide new insights and useful findings related to nutrition education research, practice and policy. The content areas of JNEB reflect the diverse interests in nutrition and physical activity related to public health, nutritional sciences, education, behavioral economics, family and consumer sciences, and eHealth, including the interests of community-based nutrition-practitioners. As the Society''s official journal, JNEB also includes policy statements, issue perspectives, position papers, and member communications.
