Abstract：
OBJECTIVE: Test an obesity intervention for families with low incomes.
METHODS: A total of 208 families were included (a parent with a body mass index [BMI] ≥ 30 and a child aged 6-12 years). A 12-month randomized controlled trial combining family health coaching (motivational interviewing) and connection to community resources. Comparison group: referrals for basic needs, written educational materials. Questionnaires, accelerometry, and anthropometrics. Intention-to-treat analysis of change in outcomes. Two-sided t test with multiple imputation.
RESULTS: Parents were 95% female, 31% Black, and 27% Hispanic. Children had a mean BMI-Z score of 1.15. Primary outcomes did not differ between groups at 12 months. Both groups significantly (P < 0.05) improved on the Family Nutrition and Physical Activity Scale for behaviors related to childhood obesity (mean ± SE: comparison, 2.8 ± 1.0; intervention, 2.2 ± 0.9), increased child sedentary activity (comparison, 32.5 ± 12.1; intervention, 39.9 ± 12.4 min/d), and decreased child moderate-vigorous physical activity (comparison, -9.6 ± 3.3; intervention -7.0 ± 3.0 min/d). Parents had no change in BMI.
CONCLUSIONS: We successfully embedded screening and referral to address social needs within an obesity intervention. The coaching intervention did not provide additional benefits. Future research could explore ways to make these interventions more accessible, valuable, and effective for families.

摘要：
目标：测试低收入家庭的肥胖干预措施。
方法：共纳入208个家庭（体重指数[BMI]≥30的父母和6-12岁的儿童）。一项为期12个月的随机对照试验，结合了家庭健康指导（动机性访谈）和与社区资源的联系。比较组：基本需求转介，书面教育材料。问卷调查，加速计,和人体测量学。结果变化的意向治疗分析。具有多重插补的双侧t检验。
结果：父母95%为女性，31%黑色,和27%的西班牙裔。儿童的平均BMI-Z评分为1.15。在12个月时，两组之间的主要结局没有差异。两组在家庭营养和身体活动量表上对与儿童肥胖相关的行为均有显着改善（P<0.05）（平均值±SE：比较，2.8±1.0；干预，2.2±0.9),儿童久坐活动增加(比较，32.5±12.1；干预，39.9±12.4min/d),和减少儿童中等强度的体力活动(比较，-9.6±3.3；干预-7.0±3.0min/d）。父母的BMI没有变化。
结论：我们成功地将筛查和转诊纳入肥胖干预中，以满足社会需求。教练干预没有提供额外的好处。未来的研究可以探索使这些干预更容易获得的方法，有价值,对家庭有效。
