WEDNESDAY, May 1, 2019 (HealthDay News) — The prevalence of current cigarette smoking is lower among pregnant women, while prevalence of current electronic cigarette smoking is equivalent for pregnant and nonpregnant women of reproductive age, according to a research letter published online April 29 in JAMA Pediatrics<\/i>.<\/p>\n
Buyun Liu, M.D., Ph.D., from the University of Iowa in Iowa City, and colleagues used data from the National Health Interview Survey to estimate the prevalence of e-cigarette and conventional cigarette use among women aged 18 to 44 years. Data were included for 27,920 women (1,071 pregnant women and 26,849 nonpregnant women).<\/p>\n
The researchers found that weighted prevalence of current conventional cigarette use was 8 and 14.3 percent among pregnant and nonpregnant women, respectively (P = 0.01 for difference). Weighted prevalence of current e-cigarette use was 3.6 and 3.3 percent among pregnant and nonpregnant women, respectively (P = 0.92 for difference). The prevalence of current e-cigarette use differed by conventional smoking status: The weighted prevalence of current e-cigarette use was 38.9, 1.3, and 0.3 percent, respectively, among current conventional cigarette smokers, former smokers, and never smokers among pregnant women; among nonpregnant women, the weighted prevalence was 13.5, 8.8, and 0.7 percent for current conventional cigarette smokers, former smokers, and never smokers.<\/p>\n
“The prevalence of current e-cigarette use was high among pregnant women who currently used conventional cigarettes,” the authors write. “It is possible that some pregnant women perceived e-cigarettes as a safe alternative to conventional cigarettes.”<\/p>\n
