Exposure to Tobacco Smoke and Temperament among U.S. Children 0–5 Years Old
Abstract Objectives This study examined the association between tobacco smoke exposure (TSE) and temperament among children 0–5 years old overall and within age groups: 0–2 and 3–5 years. Methods Data were obtained from the 2017–2018 NSCH (N = 14,345). TSE status was defined as whether children lived with a smoker who: does not smoke inside the home (no home TSE) or smokes inside the home (home TSE). We conducted logistic regression analyses while controlling for covariates. Results Overall, 12.5% of children lived with a smoker with no home TSE and 1.1% had home TSE. Children with home TSE were at increased odds to not always: be affectionate and tender (aOR = 1.74, 95% CI = 1.18–2.58), show interest and curiosity (aOR = 1.81, 95% CI = 1.23–2.68), and smile and laugh (aOR = 1.77, 95% CI = 1.13–2.77) than those with no TSE. Among 0- to 2-year-olds, those with home TSE were more likely to not always be affectionate and tender (aOR = 1.97, 95% CI = 1.04–3.74). Among 3- to 5-year-olds, those who lived with a smoker with no home TSE were more likely to not always: bounce back quickly (aOR = 1.21, 95% CI = 1.05–1.40) and smile and laugh (aOR = 1.26, 95% CI = 1.03–1.54), and those with home TSE were more likely to not always: show interest and curiosity (aOR = 2.24, 95% CI = 1.40–3.59) and smile and laugh (aOR = 2.43, 95% CI = 1.43–4.11). Conclusions Tobacco smoke-exposed children were at increased odds of not always demonstrating positive early childhood temperament behaviors, with 3- to 5-year-olds having more pronounced odds.
