Abstract
OBJECTIVES: Understanding patterns of parental tobacco use and their association with child exposure can help us target interventions more appropriately. We aimed to examine the association between parental smoking practices and cotinine levels of hospitalized children. METHODS: This is a secondary analysis of data collected from parents of hospitalized children, recruited for a cessation intervention randomized controlled trial. Smoking parents were identified by using a medical record screening question. Parent-reported demographics and smoking habits were compared to child urine cotinine by using geometric means and log-transformed cotinine levels in multivariable linear regression analyses. RESULTS: A total of 213 patients had complete baseline parent-interview and urine cotinine data. The median age was 4 (interquartile range: 1-9); 57% were boys; 56% were white, 12% were Black, and 23% were multiracial; 36% identified as Hispanic. Most families (54%) had 1 smoker in the home; 36% had 2, and 9% had ≥3. Many (77%) reported having a ban on smoking in the home, and 86% reported smoking only outside. The geometric mean cotinine level of the cohort was 0.98 ng/mL. Higher cotinine levels were associated with more smokers in the home (ratio of 2.99) and smoking inside the house (ratio of 4.11). CONCLUSIONS: Having more smokers in the home and parents who smoke inside are associated with increased smoke exposure; however, even children whose families who smoke only outside the home have significant levels of cotinine, a marker for toxin exposure.
