Smoking during pregnancy has adverse health consequences for the mother and fetus. E-cigarettes could aid with smoking cessation but there is limited research on the prevalence and patterns of e-cigarette use, and their association with smoking cessation among pregnant smokers. We conducted a secondary analysis of a randomized controlled trial of a text-messaging program for smoking cessation among a U.S. national cohort of pregnant smokers (n = 428). Outcomes assessed were trajectories of e-cigarettes use from baseline to one-month follow-up, and longitudinal association between e-cigarette use at baseline and smoking cessation at one-month follow-up. At baseline, 74 (17.29%) pregnant smokers used e-cigarettes in the past 30 days and 36 (8.41%) used e-cigarettes in the past 7 days. The primary reason stated for using e-cigarettes during pregnancy was for quitting. E-cigarette use between baseline and 1-month was inconsistent. Of 36 dual-users at baseline, 20 (55.56%) stopped using e-cigarettes by the 1-month follow-up and 14 initiated e-cigarette use. There was no evidence of an association between e-cigarette use at baseline and the primary smoking cessation outcome, 7-day point prevalence abstinence [adjusted odds ratio = 0.79, 95% confidence intervals = 0.33–1.92]. A secondary analysis of a national sample of pregnant smokers indicates that use of e-cigarettes is inconsistent and is not associated with improved smoking cessation outcomes. There is an urgent need to further examine the risk and benefits of e-cigarette use, especially during pregnancy.

Several barriers to successful breastfeeding exist, including a lack of support from peers or professionals. With the emergence of mobile health (mHealth) tools to provide additional breastfeeding support, a more thorough review of social support resources was needed. The aim of this study was to determine mHealth breastfeeding support resources and characterize the type of social support they provide. A content analysis of mHealth programs (n = 65), including text messaging (n = 12) and mobile applications (n = 53), was conducted on the basis of searches of the iTunes and Google Play stores (n = 50) and PubMed, the Cumulative Index of Nursing and Allied Health, and American Business Information/INFORM Complete Plus (n = 15). Results were then dual-coded for key characteristics and types of support provided. Thirty-eight apps (76%) were free to users, 14 (28%) were offered in a variety of languages, and 47 (94%) provided informational support. The mobile applications were targeted largely to postpartum women, focused on breastfeeding duration, and included troubleshooting information. Mobile applications often included media components (n = 12 [24%]); few were tailored or personalized (n = 5 [10%]) and interactive (n = 15 [30%]). Text-messaging programs were available in a variety of countries (n = 7 [58%]) and provided mostly informational support (n = 5 [42%]), were pro-breastfeeding (n = 12 [100%]), were targeted to both pregnant and postpartum women (n = 6 [50%]), focused on both breastfeeding initiation and duration (n = 9 [75%]), and had two-way interactivity (n = 6 [50%]) and personalization (n = 5 [42%]). Although freely available mobile applications and text-messaging programs exist, with potential for wide reach, the majority provide only informational support. These programs would benefit from additional study of their usefulness.

In the U.S., uptake of the HPV vaccine remains below coverage goals. There is concern that negative reactions to emergency initiatives during the COVID-19 pandemic, including vaccination, may have increased some parents' hesitancy towards all vaccines, including HPV. Understanding how different parent populations view routine vaccination post-pandemic is key to strategic efforts to maintaining and increasing uptake of HPV vaccine. In early 2022, we recruited an online panel of English-speaking U.S. parents and caregivers, who used the social media platform Twitter and had HPV vaccine-eligible but unvaccinated children age 9-14 years. Respondents completed a 20-minute survey measuring knowledge, attitudes and intentions regarding HPV vaccination for their child, as well as background socio-demographics and health information-seeking practices. Questions regarding experiences during the COVID-19 pandemic included changes in access to preventive care, and perceptions of whether pandemic experiences had positively or negatively affected their attitudes about routine vaccination, with open text capturing reasons for this change. Among 557 respondents, 81 % were definitely or likely to vaccinate their child against HPV, with 12 % being uncertain, and 7 % unlikely to vaccinate. Regarding routine vaccination, most (70 %) felt their attitudes had not changed, while 26 % felt more positively, and only 4 % felt more negatively. Reasons for positive attitude change included increased appreciation for vaccines overall, and motivation to proactively seek preventive care for their child. Negative attitude changes stemmed from distrust of COVID-19 public health efforts including vaccine development, and disillusionment with vaccines' ability to prevent disease. In multivariable models, intention to vaccinate was greater among parents reporting greater education, Democratic affiliation, greater religiosity, and urban residence. Negative attitude change due to the pandemic independently predicted reduced HPV vaccination intention, while positive attitude change predicted positive intention. Post-pandemic, most U.S. parents remain committed to vaccinating their children against HPV. However, addressing residual COVID-19 concerns could improve uptake among vaccine-hesitant parents.
