Identify weight-related beliefs of college students and test the predictive power of the Health Belief Model for body mass index (BMI).
Cross-sectional online survey with beliefs measured on 5-point scales.
University in North Carolina.
Undergraduates (n = 516; 91.9%), females (n = 399; 71.3%), white non-Hispanic students (n = 507; 86.2%), and 20.3% of overweight or obese status.
Perceived severity, susceptibility, barriers, benefits, and internal and external cues to action.
One-way ANOVA and regression. Significance was P < .05.
Strongest beliefs concerned benefits of healthy eating and physical activity (mean, 4.1 ± 0.7); weakest beliefs concerned barriers to adopting such behaviors (mean, 2.6 ± 0.9). The regression model was statistically significant (P < .001) and explained 17% of variance in BMI (multivariate coefficient = 0.177). Perceived severity, susceptibility, external cues, barriers, and benefits predicted BMI.
Several beliefs were identified that could serve as the basis for weight-related interventions addressing specific concerns, needs, and goals of college students.
确定大学生的体重相关信念，并检验健康信念模型对体重指数（BMI）的预测能力。
采用横断面在线调查，使用 5 点量表测量信念。
北卡罗来纳州的一所大学。
本科生（n=516；91.9%），女性（n=399；71.3%），白人非西班牙裔学生（n=507；86.2%），超重或肥胖的占 20.3%。
感知严重程度、易感性、障碍、益处，以及行动的内部和外部线索。
单因素方差分析和回归。显著性水平为 P<0.05。
最强烈的信念是关于健康饮食和体育活动的益处（平均值为 4.1±0.7）；最薄弱的信念是关于采取这些行为的障碍（平均值为 2.6±0.9）。回归模型具有统计学意义（P<0.001），并解释了 BMI 变异的 17%（多元系数=0.177）。感知严重程度、易感性、外部线索、障碍和益处都预测了 BMI。
确定了一些信念，可以作为针对大学生特定关注、需求和目标的体重相关干预的基础。
