INSIGHT Responsive Parenting Intervention and Infant Sleep

Ian M Paul et al. Pediatrics. 2016 Jul.

Abstract

Objectives: Inadequate sleep during infancy is associated with adverse outcomes for infants and families. We sought to improve sleep behaviors and duration through a responsive parenting (RP) intervention designed for obesity prevention.

Methods: The Intervention Nurses Start Infants Growing on Healthy Trajectories (INSIGHT) study is a randomized trial comparing a RP intervention with a safety control. Primiparous mother-newborn dyads were randomized after childbirth, and research nurses delivered intervention content at home visits at infant ages 3, 16, 28, and 40 weeks and at a research center visit at 1 year. The RP sleep component included developmentally appropriate messages about bedtime routines, sleep location and behaviors, and responses to wakings. Portions of the Brief Infant Sleep Questionnaire were administered 2, 8, and 52 weeks after birth with expanded sleep-related data collection at 16 and 40 weeks.

Results: Two hundred and seventy-nine dyads completed the first home visit; 90.7% completed the 1-year visit. Compared with controls, RP group infants were less likely to have prolonged bedtime routines >45 minutes and more likely to have earlier bedtimes at 16 and 40 weeks. They were less likely to be fed immediately before bed and more likely to self-soothe to sleep. At 8, 16, and 40 weeks, RP group nocturnal sleep duration was longer by 35, 25, and 22 minutes, respectively (P < .05 for all). Sleep duration at 1 year was similar between groups.

Conclusions: The INSIGHT RP intervention positively influenced developmentally appropriate bedtime routines, sleep-related behaviors, and sleep duration for infants.
