We examined the impact of a maternal-child home visitation program on birth spacing for first-time Latina mothers, focusing on adolescents and women who identified as Mexican or Puerto Rican.
This was a retrospective cohort study. One thousand Latina women enrolled in the Pennsylvania Nurse-Family Partnership between January 1, 2003, and December 31, 2007, were matched to nonenrolled Latina women using propensity scores. The primary outcome was the time to second pregnancy that resulted in a live birth (interpregnancy interval). Proportional hazards models and bootstrap methods compared the time to event.
Home visitation was associated with a small decrease in the risk of a short interpregnancy interval (≤ 18 months) among Latina women (hazards ratio [HR] = 0.86; 95% confidence interval [CI] = 0.75, 0.99). This effect was driven by outcomes among younger adolescent women (HR = 0.80; 95% CI = 0.65, 0.96). There was also a trend toward significance for women of Mexican heritage (HR = 0.74; 95% CI = 0.49, 1.07), although this effect might be attributed to individual agency performance.
Home visitation using the Nurse-Family Partnership model had measurable effects on birth spacing in Latina women.
我们研究了母婴家庭访视计划对初次生育的拉丁裔母亲生育间隔的影响，重点关注青少年和自认为是墨西哥裔或波多黎各裔的女性。
这是一项回顾性队列研究。2003 年 1 月 1 日至 2007 年 12 月 31 日期间，有 1000 名拉丁裔妇女参加了宾夕法尼亚州的护士家庭伙伴关系项目，她们与未参加该项目的拉丁裔妇女通过倾向得分进行匹配。主要结局是导致活产的第二次妊娠的时间（妊娠间隔）。比例风险模型和自举法比较了事件发生的时间。
家庭访视与拉丁裔妇女短妊娠间隔（≤18 个月）风险的小幅度降低相关（风险比 [HR] = 0.86；95%置信区间 [CI] = 0.75, 0.99）。这种效果是由年轻青少年女性（HR = 0.80；95% CI = 0.65, 0.96）的结局驱动的。对于墨西哥裔女性也存在显著趋势（HR = 0.74；95% CI = 0.49, 1.07），尽管这种效果可能归因于个体机构的表现。
使用护士家庭伙伴关系模式的家庭访视对拉丁裔妇女的生育间隔有可衡量的影响。
