Sex differences in associations between receiving and sharing tobacco-related information and tobacco product use among Appalachian Youth.
INTRODUCTION
Given that Appalachian youth tobacco use rates are higher than the US national average, it is important to understand whether sex differences shape associations between receiving and sharing product information and using tobacco.


METHODS
Middle and high school students in rural Appalachia (n=1038) were surveyed about tobacco-related perceptions and behaviors, including ways youth receive and share conventional tobacco-related and e-cigarette-related information. Youth were characterized as tobacco users (i.e. ever or current users of cigarettes, smokeless tobacco, or e-cigarettes) or never users. Descriptive characteristics were compared by tobacco use and sex. Adjusted logistic regression models evaluated associations between communication channels and tobacco use. Models were stratified by sex to examine effect modification.


RESULTS
Approximately one-third of Appalachian youth (33.8%) were tobacco users and use varied by sex (males: 54.4%; females: 45.6%). Male (OR=1.75; 95% CI: 1.18-2.60) and female (OR=2.30; 95% CI: 1.53-3.47) youth who received e-cigarette-related information through friends and family (FF) had higher odds of tobacco use. Additionally, females who received e-cigarette-related information through public displays and digital media had nearly two-fold increased odds of tobacco use. Although sharing conventional tobacco-related and e-cigarette-related information through FF was associated with increased odds of tobacco use among both sexes, these relationships were stronger among females.


CONCLUSIONS
Although specific communication channels were associated with tobacco use, associations involving receiving and sharing e-cigarette information were more pronounced in female tobacco users. Consideration of sex differences in how youth receive and share tobacco-related information may benefit tobacco prevention interventions.
