To increase understanding about the healthfulness of school lunch and participation, this study measured 3 school lunch variables, students' perception of healthfulness, objective healthfulness, and participation, and examined associations between each pair of variables (3 associations).
Multilevel models were used for a secondary analysis of data from the Healthy Communities Study, a 2013-2015 observational study of schools (n = 423) and children (n = 5,106) from 130 US communities.
Students who reported that school lunches were sometimes, often, or very often healthy ate school lunches more frequently per week (β = .71; P < .001) than did students who responded never or rarely. No associations were found with objective school lunch healthfulness.
Student perception of healthfulness of school lunch is positively associated with participation but not with objective school lunch healthfulness. Understanding how student perception is associated with participation can inform effective communications to students to increase participation in the school lunch program.
为了增进对学校午餐健康性和参与度的了解，本研究测量了 3 个学校午餐变量，即学生对健康性的感知、客观健康性和参与度，并检验了每对变量之间的关联（3 种关联）。
对来自美国 130 个社区的 130 所学校（n=423）及其学生（n=5106）的 2013-2015 年观察性研究“健康社区研究”的数据进行了二次分析，采用多层模型进行分析。
报告学校午餐有时、经常或非常健康的学生每周吃学校午餐的频率更高（β=0.71；P<0.001），而从未或很少报告的学生则吃得更少。学生对学校午餐健康性的感知与客观学校午餐健康性之间没有关联。
学生对学校午餐健康性的感知与参与度呈正相关，但与客观学校午餐健康性无关。了解学生感知与参与度的关联方式，可以为加强与学生的有效沟通提供信息，以增加他们对学校午餐计划的参与度。
