高摄入量的含糖饮料（SSB）已被认为有助于儿童肥胖症的流行，然而，家庭食品环境如何影响儿童摄入SSB的西班牙裔家庭仍然知之甚少。评估家庭食物环境和西班牙裔儿童饮食与体重状况和胰岛素抵抗（IR）之间的关系。对187名西班牙裔儿童（年龄10至14岁）进行了食物频率问卷调查，并进行了人体测量。采用胰岛素抵抗的稳态模型评估（HOMAIR），从空腹胰岛素和葡萄糖水平估计IR。父母报告了家庭人口统计数据和家庭食品环境。结构方程模型的方法被用来检查变量之间的假设关系。儿童期超重和肥胖患病率为52.8%，与HOMAIR呈正相关（β=0.687，P <0.0001）。儿童的SSB消耗量与儿童的BMI z评分呈正相关（β=0.151，P <0.05），随后与HOMAIR呈正相关。家庭可用性（β=0.191）和父母摄入SSB（β=0.419）对儿童SSB摄入量有预测作用（P <0.05）。模型拟合指数[X ~ 2 = 45.821（d.f. = 30，P > 0.01和< 0.05），X2/d. f. = 1.53，RMSEA = 0.053（90% C.I. = 0.016，0.082），CFI = 0.904]的拟合优度较好。家庭食物环境和父母的饮食似乎在儿童获得和摄入SSB中起着重要作用，这反过来又预测了儿童的体重状况。
High intake of sugar-sweetened beverages (SSB) has been suggested to contribute to the pediatric obesity epidemic, however, how the home food environment influence children’s intake of SSB among Hispanic families is still poorly understood. To evaluate the relationships between the home food environment and Hispanic children’s diet in relation to weight status and insulin resistance (IR). A food frequency questionnaire was administered to 187 Hispanic children (ages 10 to 14 years), and anthropometrics were measured. IR was estimated from fasting insulin and glucose levels using the homeostasis model assessment of insulin resistance (HOMAIR). Parents reported on family demographics and the home food environment. A structural equation modeling approach was applied to examine the hypothesized relationships among variables. The prevalence of childhood overweight and obesity was 52.8% and it was positively associated with HOMAIR (β=0.687, P <.0001). Children’s SSB consumption was positively associated with children’s BMI z-score (β=0.151, P <0.05) and subsequently to HOMAIR. Children’s SSB consumption was predicted by home availability (β=0.191) and parental intake of SSB (β=0.419) (P <0.05). The model fit indices [X2 = 45.821 (d.f. = 30, P > 0.01 and < 0.05), X2/d.f. = 1.53, RMSEA = 0.053 (90% C.I. = 0.016, 0.082), CFI = 0.904] suggested a satisfactory goodness-of-fit. The home food environment and parental diet seem to play an important role in the children’s access to and intake of SSB, which in turn predicted children’s weight status.
