A significant increase in the incidence of pediatric obesity has been reported in Texas. This study evaluated how effectively the Texas Public School Nutrition Policy promoted the understanding of proper nutrition by fourth-grade schoolchildren and their parents in three school districts in Bell County and Harris County. Fourth-grade schoolchildren were surveyed at two times (T1, T2) during the spring semester of the 2004-2005 school year to assess their dietary intake, their health-related quality of life (HRQOL), and their understanding and satisfaction with the Texas Public School Nutrition Policy. Participating students' parents also were surveyed. The overall obesity rate in surveyed children averaged 26.1%. No significant difference was found between HRQOL scores for obese and normal-weight children, although HRQOL scores for normal-weight children were significantly lower than those in previous population studies of healthy children. In addition, the HRQOL scores of obese and healthy children increased significantly from T1 to T2 for Bell County but only for healthy children in Harris County. Children from Bell County were more likely to eat food from the cafeteria while children from Harris County were more likely to eat food brought from home. Parents of minority children reported that they were more likely to change dietary habits at home as a result of the Texas Public School Nutrition Policy. Obese children were less likely than normal-weight children to try to lose weight. This study suggests that lunch intake varies considerably in Texas, and state policy should try to institute more uniform nutrition guidelines for all school districts. Because minority children are at increased risk of obesity, the preliminary findings that their parents are more likely to change their dietary habits at home are very encouraging.
据报道,得克萨斯州儿童肥胖症的发病率显著上升。本研究评估了得克萨斯州公立学校营养政策在贝尔县和哈里斯县的三个学区中,对四年级学童及其家长正确营养观念的促进效果。在2004 - 2005学年春季学期,对四年级学童进行了两次调查(T1、T2),以评估他们的饮食摄入量、健康相关生活质量(HRQOL),以及他们对得克萨斯州公立学校营养政策的理解和满意度。参与调查学生的家长也接受了调查。被调查儿童的总体肥胖率平均为26.1%。肥胖儿童和正常体重儿童的HRQOL得分之间没有显著差异,尽管正常体重儿童的HRQOL得分显著低于之前对健康儿童的人群研究中的得分。此外,贝尔县肥胖儿童和健康儿童的HRQOL得分从T1到T2显著增加,但哈里斯县只有健康儿童的得分增加。贝尔县的儿童更有可能在学校食堂就餐,而哈里斯县的儿童更有可能吃从家里带来的食物。少数族裔儿童的家长报告说,由于得克萨斯州公立学校营养政策,他们更有可能在家中改变饮食习惯。肥胖儿童比正常体重儿童减肥的可能性更小。这项研究表明,得克萨斯州的午餐摄入量差异很大,州政策应努力为所有学区制定更统一的营养指南。由于少数族裔儿童肥胖风险增加,其家长更有可能在家中改变饮食习惯这一初步发现非常令人鼓舞。
