Family matters: the influence of partner and familial encouragement on home and car smoking bans

Background Secondhand smoke exposure (SHSe) poses health risks to neonatal intensive care unit (NICU) infants after they are discharged; these risks can be mitigated by the implementation of parent-enforced total home and car smoking bans. Understanding the influence that various family members have on household smoking policies may inform interventions to reduce SHSe among vulnerable infants.

Methods In a cross-sectional, secondary analysis of data collected between 2013 and 2015, mothers of NICU infants who reported smoking or living with a smoker (N=242) were asked about whether members of 9 separate relationship types (e.g., partner, mother, father) encouraged or discouraged smoking in the home and car. The influence of perceived encouragement from each relationship type on the odds of having a total smoking ban in place was estimated.

Results Participants reported that partners (47%) and siblings (32%) were most likely to encourage smoking in the home/car. In a multivariate model, both partner (p=0.0002) and sibling (p=0.004) encouragement of indoor smoking decreased the likelihood of having a total smoking home and car ban in place.

Conclusions Family members have significant influence on SHSe reduction practices. Innovative family-based interventions may be needed in order to reduce SHSe in this particularly vulnerable group of infants.
