: Self-rated health (SRH) is consistent with objective health status and can serve as a global measure of health status in the general population. The purpose of this study is to find the connections of dietary habits, leisure-time exercise, exercise attitude, and body mass index (BMI) to SRH among college students. : The "dietary⁻exercise attitude and SRH" questionnaire was developed to investigate college students in Taiwan through the Internet. Partial least squares structural equation modeling (PLS-SEM) was used to test the relationship among them. : The reliability and validity were confirmed using PLS-SEM. The results found exercise habits, dietary habits, and BMI explained 26.5% of SRH. Poor dietary habits and being overweight led to bad health status (negative path coefficients to SRH). Additionally, the study found that positive exercise attitude had a positive relationship with exercise habits. : Based on the results, college students should be well-informed of the potential threat of poor dietary habits and being overweight to health and should improve their attitude with respect to exercise so as to prevent overweight-related diseases.
自评健康（SRH）与客观健康状况一致，可以作为一般人群健康状况的全球衡量标准。本研究旨在探讨饮食习惯、休闲时间运动、运动态度和体重指数（BMI）与大学生 SRH 的关系。
通过互联网，开发了“饮食-运动态度与 SRH”问卷，对台湾的大学生进行了调查。采用偏最小二乘法结构方程建模（PLS-SEM）对它们之间的关系进行了测试。
使用 PLS-SEM 验证了可靠性和有效性。结果发现，运动习惯、饮食习惯和 BMI 解释了 26.5%的 SRH。不良的饮食习惯和超重会导致健康状况不佳（对 SRH 的负路径系数）。此外，研究还发现，积极的运动态度与运动习惯呈正相关。
基于这些结果，大学生应该充分了解不良饮食习惯和超重对健康的潜在威胁，并改善他们对运动的态度，以预防与超重相关的疾病。
