刚到美国时，新移民中超重和肥胖的患病率低于美国本土居民。随着在美国居住时间的延长，这些差异会随着时间的推移而趋同，随后移民中的患病率高于美国本土居民。来自大波士顿地区Live Well项目的结果表明，利用文化适应性、基于社区的参与性研究（CBPR）方法来减少新移民母子二人组体重增加的可行性。海地、拉丁美洲和巴西的母子二人组（n = 390），新到美国（不到10年），参加了一到两年的CBPR生活方式干预，以饮食和身体活动行为为目标。记录出勤情况以确定剂量。在基线、6个月、12个月、18个月和24个月收集参与者的人口统计学、人体测量学和相关协变量。身体质量指数（BMI）采用客观测量的身高和体重计算。采用线性混合回归模型分别评估母亲和儿童BMI和BMI z-score的变化。基线时，近75%的母亲和50%的儿童超重或肥胖（BMI≥25.0和BMI z-score≥85百分位）。只有20%的母亲在第一年参加了全部12次干预。通过意向治疗分析，在随访中没有观察到显著的时间、干预或时间×干预对母亲或儿童体重变化的影响。与低分位数的母亲（包括没有接触的母亲）相比，最高分位数的母亲（参加了所有12个干预课程的母亲）在18个月时（低1.76个单位，95%CI: -3.14, -0.37）和24个月时（2.61个单位，95%CI: -3.92, -1.29）的BMI显著降低。在儿童中没有发现这种剂量效应对BMI z分数的影响。Live Well的研究结果证明了利用CBPR方法解决移民母亲超重和肥胖问题的可行性。考虑到在美国居住6年以上的母子中超重和肥胖的患病率高于预期，以及较低的母亲参与干预的比例，需要进一步的研究来确定最佳的干预时间、保留策略和方法，以共同支持健康的母亲和儿童体重。
Upon arrival, the prevalence of overweight and obesity is lower in new immigrants than their native counterparts in the U.S. With longer residency in the U.S., these differences converge over time, followed by higher prevalence among immigrants than native U.S. residents. Results from the Live Well project in the Greater Boston area demonstrate the viability of utilizing a culturally adapted, community-based participatory research (CBPR) approach to reduce weight gain among newly immigrated mother–child dyads. Haitian, Latina, and Brazilian mother–child dyads (n = 390), new to the U.S. (fewer than 10 years) were enrolled in a one- to two-year long CBPR lifestyle intervention that targeted dietary and physical activity behaviors. Attendance was recorded to establish dose. Demographics, anthropometrics, and relevant covariates were collected from participants at baseline, 6, 12, 18, and 24 months. Body Mass Index (BMI) was calculated using objectively measured height and weight. Linear mixed regression models were used to assess change in BMI and BMI z-score of mothers and children respectively. At baseline, nearly 75% of mothers and 50% of children were either overweight or obese (BMI ≥ 25.0 and BMI z-score ≥ 85th percentile, respectively). Only 20% of mothers attended all 12 intervention sessions in year 1. Using intent-to-treat analyses, no significant time, intervention, or time × intervention effects were observed for weight change of mothers or children at follow-up. Mothers in the highest quantile (those who attended all 12 intervention sessions) had significant reductions in BMI at 18 months (1.76 units lower, 95%CI: -3.14, -0.37) and 24 months (2.61 units, 95%CI -3.92, -1.29) compared to mothers in the lower quantiles, including those with no exposure. Such dose effects on BMI z-scores were not noted for children. Findings from Live Well demonstrate the viability of utilizing a CBPR approach to address overweight and obesity among immigrant mothers. Given the higher-than-expected prevalence of overweight and obesity among mother–child dyads by ~ 6 years of U.S. residency, and lower maternal participation rates in the intervention, additional research is necessary to identify the optimal intervention length, retention strategies, and approach to jointly support healthy maternal and child weight.
