美国的Head Start计划为低收入学龄前儿童及其照顾者提供服务，并为肥胖问题提供评估和干预的机会。我们试图确定儿童和他们的照顾者中肥胖的流行程度，并确定与儿童BMI z得分(BMIz)和照顾者BMI相关的变量。从阿拉巴马州和德克萨斯州的57个Head Start中心招募的770名照顾者-儿童二人组的饮食和BMI的横断面数据。每个照顾者和孩子的身高和体重都使用标准化方案进行测量。使用三个24小时饮食回忆和阻止食物频率问卷收集照顾者-儿童二人组的饮食摄入量。数据收集于2004年9月至2005年11月之间。较大的食物金字塔类别被分成17个食物消费组，并测试它们与儿童BMIz的关联。使用方差分析来测试食物组是否与儿童BMIz显著相关。黑人(B)、西班牙裔(H)和白人(W)儿童肥胖率分别为18.4%、24.3%和37.3%(P<；0.0001)，而B、H和W照顾者的肥胖率分别为58.3%、41.4%和41.6%(P<；0.0001)。儿童体重指数与照顾者体重指数呈正相关(r=0.16P<；0.0001)。在多变量模型中，如果照顾者肥胖，儿童患体重指数≥第95百分位数的可能性是1.9(95%CI：1.31-2.74)倍。五个变量(水果、无糖饮料、低脂奶制品、种族和照顾者的BMI)与儿童BMIz显著相关。水果与儿童体重指数呈负相关，而无糖饮料、低脂奶制品和照顾者的BMI与儿童BMIz呈正相关(P<；0.03)。与白人相比，B和H儿童的BMIz较低(P<；0.05)。这一人群中肥胖率很高，再加上观察到的水果消费与BMI之间的负相关，如果在其他研究中重复的话，这表明促进水果消费的干预措施可能对儿童BMI产生有益的影响。
The United States Head Start program serves low-income preschoolers and their caregivers and provides an opportunity for assessment and intervention on obesity. We sought to determine the prevalence of obesity among children and their caregivers and to identify variables that are associated with child BMI z-scores (BMIz) and caregiver BMI. Cross-sectional data on diet and BMI from 770 caregiver-child dyads recruited from 57 Head Start centers in Alabama and Texas. Height and weight of each caregiver and child were measured using standardized protocols. Dietary intakes of caregiver-child dyads were collected using three 24-hour dietary recalls and Block Food Frequency Questionnaires. Data were collected between September, 2004 and November, 2005. The larger food pyramid categories were divided into 17 food consumption groups and tested for their association with child BMIz. ANOVA was used to test whether food groups were significantly associated with child BMIz. The prevalence of obesity among children was 18.4%, 24.3% and 37.3% among Black (B), Hispanic (H) and White (W), respectively (P<0.0001), while it was 58.3%, 41.4% and 41.6% among B, H and W caregivers, respectively (P<0.0001). Child BMIz and caregiver BMI were correlated (r=0.16, P<0.0001). In multivariable models, children were 1.90 (95% CI: 1.31-2.74) times more likely to have BMI ≥95th percentile if their caregiver was obese. Five variables (fruits, unsweetened beverages, low-fat dairy, race and caregiver’s BMI) were significantly associated with child BMIz. Fruits were inversely related, while unsweetened beverages, low-fat dairy, and caregiver’s BMI were positively associated with child BMIz (P<0.03). Compared to whites, B and H children had lower BMIz (P<0.05). The high prevalence of obesity in this population together with the observed inverse association between fruit consumption and BMI, if replicated in other studies, suggests that interventions that promote fruit consumption could have beneficial effects on child BMI.
