Few postpartum ethnic minority women perform leisure-time moderate-to-vigorous physical activity (MVPA). The study tested the effectiveness of a 12-month tailored intervention to increase MVPA in women with infants 2-12months old.
From 2008 to 2011, women (n=311) with infants (average age=5.7months) from Honolulu, Hawaii were randomly assigned to receive tailored telephone calls and access to a mom-centric website (n=154) or access to a standard PA website (n=157). MVPA was measured at baseline, 6, and 12months using self-report and acclerometers.
Controlling for covariates, the tailored condition significantly increased self-reported MVPA from an average of 44 to 246min/week compared with 46 to 156min/week for the standard condition (p=0.027). Mothers with≥2 children had significantly greater increases in MVPA in response to the tailored intervention than those with one child (p=0.016). Accelerometer-measured MVPA significantly increased over time (p=0.0001), with no condition differences. There was evidence of reactivity to initially wearing accelerometers; the tailored intervention significantly increased MVPA among women with low baseline accelerometer MVPA minutes, but not among those with high minutes (pinteraction=0.053).
A tailored intervention effectively increased MVPA over 12months in multiethnic women with infants, particularly those with more than one child.
很少有产后少数民族妇女进行休闲时间的中度至剧烈身体活动（MVPA）。本研究测试了一项为期12个月的针对性干预措施对增加有2至12个月大婴儿的妇女的MVPA的有效性。
2008年至2011年，来自夏威夷檀香山的有婴儿（平均年龄=5.7个月）的妇女（n=311）被随机分配接受针对性的电话咨询并可访问以妈妈为中心的网站（n=154）或访问标准体育活动网站（n=157）。在基线、6个月和12个月时使用自我报告和加速度计测量MVPA。
在控制协变量的情况下，与标准条件下从平均每周46分钟增加到156分钟相比，针对性条件下自我报告的MVPA从平均每周44分钟显著增加到246分钟（p=0.027）。有≥2个孩子的母亲对针对性干预的MVPA增加幅度明显大于只有一个孩子的母亲（p=0.016）。加速度计测量的MVPA随时间显著增加（p=0.0001），且无条件差异。有证据表明对最初佩戴加速度计存在反应性；针对性干预显著增加了基线加速度计MVPA分钟数较低的妇女的MVPA，但对分钟数较高的妇女则没有（p交互作用=0.053）。
一项针对性干预措施在12个月内有效增加了有婴儿的多民族妇女的MVPA，特别是那些有不止一个孩子的妇女。
