BACKGROUND Suboptimal diet quality, prevalent among postpartum women, is troubling for mothers and their children because positive relationships between maternal and child diet quality exist. OBJECTIVE The primary objective was to determine whether postnatal diet quality scores of participants in the two treatment arms differed or changed over time. DESIGN Delta Healthy Sprouts was a two-arm, randomized, controlled, comparative impact trial. PARTICIPANTS AND SETTING Pregnant women at least 18 years of age, less than 19 weeks pregnant, and residing in three Mississippi counties were recruited between March 2013 and December 2014. Postnatal data was collected from 54 participants between September 2013 and May 2016. The postnatal attrition rates were 17% and 13% for the control and experimental arms. INTERVENTION The control arm received the Parents as Teachers curriculum, and the experimental arm received a nutrition- and physical activity-enhanced Parents as Teachers curriculum. MAIN OUTCOME MEASURES Multiple-pass 24-hour dietary recalls were collected from participants at the postnatal month 1, 4, 6, 8, and 12 visits. Healthy Eating Index-2010 was used to calculate diet quality. STATISTICAL ANALYSIS PERFORMED Linear mixed models were used to test for treatment, time, and treatment by time (interaction) effects on postnatal dietary outcomes. RESULTS Control arm mean (95% confidence limits) total Healthy Eating Index-2010 scores were 36.8 (range=32.5 to 41.1), 36.5 (range=31.9 to 41.1), 40.2 (range=35.7 to 44.8), 39.3 (range=34.7 to 43.9), and 36.4 (range=31.8 to 41.0) at postnatal months 1, 4, 6, 8, and 12, respectively. Corresponding experimental arm scores were 42.3 (range=37.5 to 47.0), 41.6 (range=36.3 to 46.9), 40.2 (range=34.8 to 45.7), 45.8 (range=40.5 to 51.1), and 37.6 (range=32.6 to 42.7), respectively. Experimental scores were significantly higher than control scores across time. No other effects were significant. CONCLUSIONS Neither the standard Parents as Teachers curriculum nor the enhanced Parents as Teachers curriculum was effective at improving the poor diet quality of this cohort of rural, Southern, African-American women during the 12 months following the birth of their infant.

在农村、南部和非洲裔美国妇女的双臂随机对照影响比较试验中未观察到产后饮食结果的改善

背景在产后妇女中普遍存在的次优饮食质量对母亲和她们的孩子来说是麻烦的，因为母婴饮食质量之间存在正相关。目的 主要目的是确定两个治疗组参与者的产后饮食质量评分是否随时间不同或变化。设计 Delta Healthy Sprouts 是一项双臂、随机、对照、比较影响试验。参与者和地点 2013 年 3 月至 2014 年 12 月期间招募了居住在密西西比州三个县的 18 岁以上、怀孕不足 19 周的孕妇。从 2013 年 9 月至 2016 年 5 月期间收集了 54 名参与者的产后数据。对照组和实验组的比率分别为 17% 和 13%。干预 对照组接受家长作为教师的课程，而实验组接受加强营养和身体活动的家长作为教师的课程。主要观察指标 在产后第 1、4、6、8 和 12 个月就诊时收集参与者的多次 24 小时饮食回忆。健康饮食指数 2010 用于计算饮食质量。执行的统计分析 线性混合模型用于测试治疗、时间和治疗按时间（相互作用）对出生后饮食结果的影响。结果 对照组平均（95% 置信限）总健康饮食指数 - 2010 得分为 36.8（范围 = 32.5 到 41.1）、36.5（范围 = 31.9 到 41.1）、40.2（范围 = 35.7 到 44.8）、39.3（范围 = 34）到 43.9) 和 36.4（范围 = 31.8 到 41.0）分别在出生后第 1、4、6、8 和 12 个月。相应的实验组评分为 42.3（范围 = 37.5 至 47.0）、41.6（范围 = 36.3 至 46.9）、40.2（范围 = 34.8 至 45.7）、45.8（范围 = 40.5 至 51.1）和 37.6（范围 = 32.6） ， 分别。随着时间的推移，实验分数显着高于对照分数。没有其他影响是显着的。结论 无论是标准的家长教师课程还是增强的家长教师课程都不能有效改善这群农村、南部、非洲裔美国妇女在婴儿出生后 12 个月内的不良饮食质量。没有其他影响是显着的。结论 无论是标准的家长作为教师课程还是增强的家长作为教师课程都不能有效改善这群农村、南部、非洲裔美国妇女在婴儿出生后 12 个月内的不良饮食质量。没有其他影响是显着的。结论 无论是标准的家长教师课程还是强化的家长教师课程都不能有效改善这群农村、南部、非洲裔美国妇女在婴儿出生后 12 个月内的不良饮食质量。
