Translating pediatric primary care best practice guidelines for addressing tobacco in the WIC system

Tobacco smoke exposure (TSE) adversely affects child health. Intervention research on reducing childhood TSE and uptake of evidence-based smoking cessation programs has had limited reach in high-risk communities. Intervening in clinics delivering the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) could address overlapping public health priorities essential for healthy child development - nutrition and smoke-free environments. The Babies Living Safe and Smokefree (BLiSS) trial addresses existing gaps by implementing and evaluating a WIC in-clinic evidence-based training based on Ask, Advise, and Refer (AAR) guidelines. WIC nutrition staff (n = 67) completed surveys pre- and post-training as part of the larger BLiSS trial. Staff sociodemographic data, knowledge, and attitudes about maternal smoking and child TSE prevention, and AAR practices in clinic were collected using self-administered surveys. Pre-post outcomes were assessed using bivariate statistics and multiple regression models. Controlling for baseline AAR-related practices and other covariates, nutrition managers were more likely to engage in post-training AAR practices than nutrition assistants. Sociodemographics and smoking status were not related to post-training AAR. Lower perceived barriers and higher reported frequency of tobacco intervention practices at baseline were associated with higher engagement in post-test AAR practices. WIC-system interventions aimed at reducing child TSE and maternal tobacco smoking may be more effective if nutrition management-level staff are involved in assessment and by addressing barriers related to TSE among nutrition assistants. Findings suggest that WIC in-clinic training may help to increase self-efficacy for staff engagement in brief screening, intervention, and referral practices.
