Prevalence and Predictors of Postpartum Maternal and Infant Bed-Sharing Among Chinese-Canadian Women.

Objective/

Background

Our primary objective was to describe and identify predictors of any and predominant bed-sharing at 4 and 12 weeks postpartum among Chinese-Canadian mothers.

Participants

We conducted a longitudinal study of 570 Chinese immigrant and Canadian-born women in Toronto, Ontario.

Methods

Any bed-sharing, defined as sharing a bed or mattress for any part of the night on any night in the previous week, and predominant bed-sharing, defined as sharing a bed or mattress for most of the night, on more than half the nights of the previous week, were evaluated at 4 and 12 weeks postpartum. Predictors of bed-sharing, evaluated in multivariable logistic regression models, were background (age, parity, education, household size, delivery mode, social support), cultural (immigrant status, acculturative stress, acculturation, postpartum ritual uptake), and postpartum variables (mental health, breastfeeding problems, fatigue, sleep knowledge, plans for bed-sharing, perceptions of infant sleep problems, cognitions about infant sleep).

Results

One in five women (20.7%) reported bed-sharing as the predominant sleep location for their infant at 4 weeks postpartum, with nearly half (45.6%) reporting any bed-sharing at this time. The prevalence of any bed-sharing remained relatively stable at 12 weeks postpartum (46.5%), while predominant bed-sharing increased to 30.1%. The most consistent predictors of any and predominant bed-sharing at 4 and 12 weeks postpartum were lower education level, greater acculturative stress, and predelivery plans to bed-share.

Conclusions

These findings have implications for the development of clinical recommendations given to expectant and new parents to promote infant sleep practices that are consistent with American Academy of Pediatrics recommendations.
