To examine associations between parental limits on soft drinks and purchasing soft drinks from school vending machines and consuming soft drinks among middle school students.
Secondary analysis of cross-sectional data from the middle school Youth Risk Behavior Survey.
Eight public middle schools in central Kentucky.
All sixth- through eighth-grade students in 7 schools and all eighth-grade students in 1 school (n = 4,049).
Self-reported parental limits on soft drink intake, school vending machine soft drink purchases, soft drink consumption, and control variables.
Chi-square and binary logistic regression analyses.
Compared to students with no parental limits on soft drink consumption, students with the strictest limits were less likely to purchase soft drinks from school vending machines and consume soft drinks; conversely, students with minor parental limitations were more likely to consume soft drinks. The odds of consuming soft drinks were nearly 4 times greater when students purchased soft drinks from school vending machines than when they did not.
Further research may enhance understanding of the influence of varying degrees of parental limitations. Efforts to reduce children's soft drink consumption may be augmented by policies limiting soft drink purchases in schools.
探讨父母对软饮料的限制以及从学校自动售货机购买软饮料与中学生饮用软饮料之间的关联。
对肯塔基州中部 8 所公立中学的中学生风险行为调查的横断面数据进行二次分析。
肯塔基州中部 8 所公立中学。
7 所学校的所有六年级至八年级学生和 1 所学校的所有八年级学生（n=4049）。
父母对软饮料摄入量的限制、从学校自动售货机购买软饮料、软饮料消费以及控制变量。
卡方检验和二元逻辑回归分析。
与父母不限制软饮料消费的学生相比，限制最严格的学生从学校自动售货机购买软饮料和饮用软饮料的可能性较小；相反，父母限制较少的学生更有可能饮用软饮料。从学校自动售货机购买软饮料的学生饮用软饮料的可能性几乎是不购买的 4 倍。
进一步的研究可能会增强对不同程度父母限制影响的理解。通过限制学校购买软饮料的政策，可能会加强减少儿童软饮料消费的努力。
