目的：本研究的目的是确定是否参与了头开始与健康的变化在BMI.METHODS：样本包括儿童参与了头开始2005年和2013年之间和儿童从2个比较组从密歇根州的初级保健卫生系统：5405接受医疗补助和19320不接受医疗补助。BMI Z评分的变化，从开始到结束的每2学年和干预夏季组之间进行了比较，通过使用分段线性混合模型调整年龄，性别和种族/ethnication.RESULTS：总样本包括43 748名儿童提供83 239人体测量。开端样本是64.9%的白色，10.8%的黑人和14.4%的西班牙裔; 16.8%的儿童肥胖，16.6%的超重在最初的观察。与对照组相比，在第一学年，以肥胖进入Head Start的儿童在BMI z评分方面表现出更大的下降（β = -0.70 [SE：0.05] vs医疗补助组-0.07 [0.08][P < .001]和非医疗补助组-0.15 [SE：0.05][P < .001]）;超重儿童的情况也类似。先声夺人参与者肥胖，超重，体重不足，在后续的儿童比在comparationgroups.CONCLUSIONS：学龄前儿童与不健康的体重状况谁参加了先声夺人有一个显着健康的BMI比幼儿园入学年龄比较儿童在初级保健卫生系统（无论是那些接受和那些不接受医疗补助）。
OBJECTIVES: The goal of this study was to determine if Head Start participation is associated with healthy changes in BMI.METHODS: The sample included children participating in Head Start between 2005 and 2013 and children from 2 comparison groups drawn from a Michigan primary care health system: 5405 receiving Medicaid and 19 320 not receiving Medicaid. Change in BMI z score from the beginning to the end of each of 2 academic years and the intervening summer was compared between groups by using piecewise linear mixed models adjusted for age, gender, and race/ethnicity.RESULTS: The total sample included 43 748 children providing 83 239 anthropometric measures. The Head Start sample was 64.9% white, 10.8% black, and 14.4% Hispanic; 16.8% of the children were obese and 16.6% were overweight at the initial observation. Children who entered Head Start as obese exhibited a greater decline in the BMI z score during the first academic year versus the comparison groups (beta = -0.70 [SE: 0.05] vs -0.07 [0.08] in the Medicaid group [P < .001] and -0.15 [SE: 0.05] in the Not Medicaid group [P < .001]); patterns were similar for overweight children. Head Start participants were less obese, less overweight, and less underweight at follow-up than children in the comparison groups.CONCLUSIONS: Preschool-aged children with an unhealthy weight status who participated in Head Start had a significantly healthier BMI by kindergarten entry age than comparison children in a primary care health system (both those receiving and those not receiving Medicaid).
