In this egocentric network study, we explored Chinese collectivism in relation to social network characteristics and sex work-related stigma among mid-age female sex workers (FSWs). Respondent-driven sampling was used to recruit 1245 mid-age FSWs from three cities in China. We found that a one standard deviation (SD) increase in FSWs’ collectivism was associated with a 0.18 SD decrease in social support (95% CI − 0.32, − 0.04), a 0.20 SD decrease in network effective size (i.e., the diversity of a social network; 95% CI − 0.30, − 0.10), and a 0.21 SD decrease in network betweenness (i.e., the “bridging potential” of egos within their networks; 95% CI − 0.33, − 0.09). Among participants who perceived more sex work stigma, the association between collectivism and FSWs' network betweenness was attenuated. In a collective culture emphasizing group values and honor, belonging to a less interconnected social network may give FSWs a structural advantage to cope with stigma and secure social support.

The aim of this study was to assess university students' knowledge and understanding about HPV and its association with their vaccination status and health literacy. A sample of 383 undergraduate university students between the ages of 18 and 26 were recruited between February 14 and March 22, 2018. An electronic survey was administered to assess knowledge and HPV awareness, vaccination status, and health literacy. Participants had moderate mean knowledge scores of 6.02 of a possible 11 (SD = 3.06). There was a positive association between health literacy and HPV knowledge and a statistically significant difference in knowledge scores between those who are vaccinated and unvaccinated p < 0.001. This study expanded available research on HPV vaccine and its uptake among university students and can be used to develop educational interventions. Continuous examination of HPV knowledge gaps and identifying factors that affect vaccine uptake is pivotal to increasing vaccination rates.

A random telephone survey of attitudes toward underage drinking was conducted in the Washington, DC, metropolitan area. The results revealed that alcohol use, especially alcohol-impaired driving, among youth were seen as serious problems by a majority (>80%) of the respondents. Strong support (>80%) was detected for imposing suffer penalties on bars and restaurants that sell alcohol to minors, older peers who purchase alcohol for minors, and driver's license restrictions for minors who possess and use alcohol. Over 50% favored stiffer penalties for parents who provide alcohol to minors. Respondents who were parents of teenage children were more likely to believe their teen's friends drink and drive (37%) than they were to believe their own teen drives drunk (10%). These parents were also unlikely to believe their teen had ever come home intoxicated (19%) despite the fact that almost 60% believed their teen has been to parties where there is drinking. These findings, and others from this survey, indicate that parents (especially whites) are unaware of the nature of teen drinking and are reluctant to accept the fact that their teens are involved with alcohol and high-risk alcohol-related behaviors. The implications of these findings for prevention programs are discussed.

This study investigated the potential effects of alcohol price increases on alcohol-related attitudes and perceptions of youth. Data were collected through a survey of high school students conducted after the federal excise taxes on alcohol beverages were increased in January 1991. Survey data lend support to previous research showing that higher alcohol prices contribute to lower alcohol consumption by youth, as well as to a decrease in related problems such as driving while intoxicated. Survey data also suggest that a price of around $7.50 for a six-pack of beer or a four-pack of wine coolers would discourage purchases by youth. Further studies are called for to substantiate and to expand on these findings with more diverse adolescent populations.

The use of a multivariate procedure is demonstrated in the analysis of a survey of various firesafety actions and beliefs in a college student population. A canonical correlation analysis identified three significant factors and revealed that performing a safety inspection of one's residence for potential hazards was associated with beliefs in one's personal efficacy in handling fire situations, whereas engaging in more emergency-related actions such as checking to see if one's smoke detector was working properly, knowing the emergency telephone number, having it posted by the telephone, and knowing two exits out of each area of the home was related to beliefs of susceptibility and seriousness concerning fires. A third factor revealed an association between having a sprinkler system (but not a fire extinguisher) present in the place of residence, vacuuming the dust from a smoke detector, and having ever practiced an emergency escape with beliefs reflecting susceptibility to future (but not present) fire hazards, adequacy of firesafety knowledge, and beliefs in the effectiveness of firesafety inspections. It is shown that the results of this analysis can be quite useful in guiding the development of firesafety education materials; also, the need to differentiate the specific motivational approach depending upon the type of firesafety action being promoted with this particular population is revealed.
