Background: 

Sleep-associated infant death is the leading cause of postneonatal mortality in the United States. Preterm infants are at higher risk for sleep-associated death, but maternal adherence to safe sleep practices is lower than for mothers of full-term infants. Data are lacking on whether maternal neonatal intensive care unit (NICU) visitation time impacts safe sleep compliance after hospital discharge.

Purpose: 

For mothers of preterm infants, to investigate the association of time days per week spent in the NICU and adherence to safe sleep practices after discharge.

Methods: 

A prospective observational study of 109 mothers with infants born at less than 32 weeks from 4 Colorado NICUs who completed a survey at 6 weeks after discharge about infant sleep practices. Maternal time spent in the NICU was defined as the average number of days spent in the NICU per week of infant hospitalization, as documented in the electronic medical record. Multivariable logistic regression models assessed the relationship between time in the NICU and safe sleep adherence. Covariates included maternal/infant characteristics significant at P < .2 level in bivariate analysis.

Results: 

Predictors of compliance with all safe infant sleep practices included public/no insurance compared with private insurance (adjusted odds ratio [AOR] 0.29; 95% confidence interval [CI] 0.09-0.96), some college/associate-level education versus bachelor's degree (AOR 5.88; 95% CI 1.21-28.67), and depression/anxiety symptoms (AOR 0.37; 95% CI 0.14-0.97). NICU visitation days was not associated with adherence to safe sleep practices.

Implications for Practice and Research: 

Maternal visitation days was not associated with adherence to safe infant sleep practices after discharge, highlighting the need to identify barriers and facilitators to engaging families about SUID risk-reducing behaviors.

新生儿重症监护病房 (NICU) 探视时间以及极早产儿母亲对安全睡眠习惯的遵守情况

背景： 

与睡眠相关的婴儿死亡是美国新生儿后死亡的主要原因。早产儿因睡眠相关死亡的风险较高，但母亲对安全睡眠习惯的遵守程度低于足月婴儿的母亲。关于孕产妇新生儿重症监护病房 ( NICU ) 探视时间是否影响出院后的安全睡眠依从性尚缺乏数据。

目的： 

对于早产儿的母亲，调查每周在新生儿重症监护室度过的时间天数与出院后遵守安全睡眠习惯的关系。

方法： 

一项前瞻性观察性研究，对象是 109 名出生在 32 周以下婴儿的母亲，这些婴儿来自科罗拉多州 4 个新生儿重症监护室，她们在出院后 6 周完成了一项有关婴儿睡眠习惯的调查。产妇在新生儿重症监护病房(NICU)的时间定义为婴儿住院期间每周在新生儿重症监护病房 ( NICU)的平均天数，如电子病历中记录的那样。多变量逻辑回归模型评估了NICU 的时间与安全睡眠依从性之间的关系。协变量包括双变量分析中P < .2 水平显着的母婴特征。

结果： 

遵守所有婴儿安全睡眠习惯的预测因素包括与私人保险相比的公共/无保险（调整后优势比 [AOR] 0.29；95% 置信区间 [CI] 0.09-0.96）、一些大学/副学士学位教育与学士学位（ AOR 5.88；95% CI 1.21-28.67），以及抑郁/焦虑症状（AOR 0.37；95% CI 0.14-0.97）。新生儿重症监护病房(NICU)探视天数与遵守安全睡眠习惯无关。

对实践和研究的影响： 

产妇探视日与出院后遵守婴儿安全睡眠习惯无关，这凸显出需要找出障碍和促进因素，让家庭参与降低SUID风险的行为。
