目的：探讨超重儿童健康素养与体重指数（BMI） Z-score的关系。方法：对超重儿童及家长进行横断面调查。采用功能健康素养短测试（STOFHLA）测量家长和儿童的健康素养。线性回归测试了儿童BMI z分数的预测因子，调整了混杂因素。结果：171例患儿中有107例（62%）参与，其中78例（73%）资料完整。儿童BMI Z-score （SD）均值为2.3 (0.40)；儿童年龄中位数（四分位数间距）为11.5（10-16岁）；女性占53%；80%是医疗补助接受者。儿童平均STOFHLA为22.9 (9.0)；父母平均STOFHLA为29.1（8.6）。儿童STOFHLA与BMI Z-score呈负相关（r = 0.37, p = 0.0009），与儿童饮食自我效能呈正相关（r = 0.40, p < 0.0001）。在调整混杂因素后，儿童STOFHLA与儿童BMI Z-score独立相关（标准化B = -0.43, p < 0.0001）。回归模型的总体调整r方为38%。儿童STOFHLA占整个模型的13%。结论：儿童健康素养与超重儿童BMI z分数呈负相关，提示在计划旨在改善儿童BMI的干预措施时，需要考虑健康素养在自我效能感和行为改变之间的交叉关系。2009爱思唯尔爱尔兰有限公司版权所有。
Objective: To test the relationship between child health literacy and body mass index (BMI) Z-score in overweight children.Methods: Cross-sectional survey of overweight children and parents. Parent and child health literacy was measured by the Short Test of Functional Health Literacy (STOFHLA). Linear regression tested for predictors of childhood BMI Z-score, adjusting for confounders.Results: Of 171 total children, 107 (62%) participated, of whom 78 (73%) had complete data for analysis. Mean child BMI Z-score (SD) was 2.3 (0.40); median child age (interquartile range) was 11.5 (10-16); 53% were female; 80% were Medicaid recipients. Mean child STOFHLA was 22.9 (9.0); mean parental STOFHLA was 29.1 (8.6). Child STOFHLA correlated negatively with BMI Z-score (r = 0.37, p = 0.0009) and positively with child eating self-efficacy (r = 0.40, p < 0.0001). After adjusting for confounders, child STOFHLA was independently associated with child BMI Z-score (standardized B = -0.43, p < 0.0001). Overall adjusted r-squared for the regression model was 38%. Child STOFHLA contributed 13% to the overall model.Conclusions: Child health literacy was negatively correlated with BMI Z-scores in overweight children, suggesting the need to consider health literacy in the intersection between self-efficacy and behavior change when planning interventions that aim to improve child BMI.
