Children, adolescents, and the media in the 21st century.
TL;DR: American children and adolescents spend an average of 3-5 hours per day with a variety of media, including television, radio, videos, videogames, and the Internet, but little research exists concerning adolescents' use of the Internet and the potential behavioral impact.
Abstract: American children and adolescents spend an average of 3-5 hours per day with a variety of media, including television, radio, videos, videogames, and the Internet. Considerable research exists to document concerns about media violence, the impact of media on teen sexual attitudes and behavior, the relationship between alcohol and cigarette advertising and adolescent drug use, and the impact of R-rated films on attitudes about sexual violence. Very little research exists concerning adolescents' use of the Internet and the potential behavioral impact, but many parents and professionals are concerned. Solutions include: better programming, stricter regulation by parents, media education at home and in schools, and greater advocacy on the part of health professionals.

TL;DR: There was a strong, direct, and independent association between seeing tobacco use in films and trying cigarettes, a finding that supports the hypothesis that smoking in films has a role in the initiation of smoking in adolescents.
Abstract: Objective: To test the hypothesis that greater exposure to smoking in films is associated with trying smoking among adolescents.
Design: Cross sectional survey of 4919 schoolchildren aged 9–15 years, and assessment of occurrence of smoking in 601 films.
Setting: Randomly selected middle schools in Vermont and New Hampshire, USA.
Main outcome measure: Number of schoolchildren who had ever tried smoking a cigarette.
Results: The films contained a median of 5 (interquartile range 1-12) occurrences of smoking. The typical adolescent had seen 17 of 50 films listed. Exposure to smoking in films varied widely: median 91 (49–152) occurrences. The prevalence of ever trying smoking increased with higher categories of exposure: 4.9% among students who saw 0–50 occurrences of smoking, 13.7% for 51–100 occurrences, 22.1% for 101-150, and 31.3% for >150. The association remained significant after adjustment for age; sex; school performance; school; parents' education; smoking by friend, sibling, or parent; and receptivity to tobacco promotions. The adjusted odds ratios of ever trying smoking for students in the higher categories of exposure, compared with students exposed to 0–50 occurrences of smoking in films, were 1.7 (95% confidence interval 1.2 to 2.4), 2.4 (1.7 to 3.4), and 2.7 (2.0 to 3.8). These odds ratios were not substantially affected by adjustment for parenting style or for personality traits of the adolescent.
Conclusion: In this sample of adolescents there was a strong, direct, and independent association between seeing tobacco use in films and trying cigarettes, a finding that supports the hypothesis that smoking in films has a role in the initiation of smoking in adolescents.
#### What is already known on this topic
What is already known on this topic Smoking is often depicted in films, and watching films is a favourite activity of adolescents
Adolescents whose favourite actors smoke in films are more likely to have tried smoking
#### What this study adds
What this study adds Adolescents' exposure to smoking in films varies widely
Adolescents with higher exposure are significantly more likely to have tried smoking, even when other factors linked with adolescent smoking have been taken into account
This study supports the hypothesis that depictions of smoking in films influence adolescents to smoke

TL;DR: There is an extensive body of literature examining the use of social media in patient and caregiver populations and much of this work is descriptive; however, with such widespread use, evaluations of effectiveness are required.
Abstract: Objective: To map the state of the existing literature evaluating the use of social media in patient and caregiver populations. Design: Scoping review. Data sources: Medline, CENTRAL, ERIC, PubMed, CINAHL Plus Full Text, Academic Search Complete, Alt Health Watch, Health Source, Communication and Mass Media Complete, Web of Knowledge and ProQuest (2000–2012). Study selection: Studies reporting primary research on the use of social media (collaborative projects, blogs/microblogs, content communities, social networking sites, virtual worlds) by patients or caregivers. Data extraction: Two reviewers screened studies for eligibility; one reviewer extracted data from relevant studies and a second performed verification for accuracy and completeness on a 10% sample. Data were analysed to describe which social media tools are being used, by whom, for what purpose and how they are being evaluated. Results: Two hundred eighty-four studies were included. Discussion forums were highly prevalent and constitute 66.6% of the sample. Social networking sites (14.8%) and blogs/microblogs (14.1%) were the next most commonly used tools. The intended purpose of the tool was to facilitate self-care in 77.1% of studies. While there were clusters of studies that focused on similar conditions (eg, lifestyle/weight loss (12.7%), cancer (11.3%)), there were no patterns in the objectives or tools used. A large proportion of the studies were descriptive (42.3%); however, there were also 48 (16.9%) randomised controlled trials (RCTs). Among the RCTs, 35.4% reported statistically significant results favouring the social media intervention being evaluated; however, 72.9% presented positive conclusions regarding the use of social media. Conclusions: There is an extensive body of literature examining the use of social media in patient and caregiver populations. Much of this work is descriptive; however, with such widespread use, evaluations of effectiveness are required. In studies that have examined effectiveness, positive conclusions are often reported, despite non-significant findings.

TL;DR: Attitude, subjective norm and perceived behavioral control had statistically significant positive associations with intention, and were each significant predictors of intention to drink regular soda and together explained 64% of its variance.
Abstract: This study identified factors that influence regular soda consumption among 707 female students, aged 13-18 years, attending North Los Angeles County public high schools. Participants completed a group-administered Theory of Planned Behavior-based questionnaire. Almost all of the participants, 96.3%, reported that they currently drink soda; 50.1% reported drinking 2 glasses of soda or more per day during the past year. Students reported drinking regular soda more than diet soda and reported drinking phosphoric acid-containing soda more than non-phosphoric acid-containing soda. Attitude, subjective norm and perceived behavioral control had statistically significant positive associations with intention, and were each significant predictors of intention to drink regular soda and together explained 64% of its variance. The strongest predictor was attitude, followed by perceived behavioral control and subjective norm. Our results suggest that efforts to reduce soda consumption among female adolescents should include parents and friends. It is also important that soda should not be excessively available at home or widely accessible to teenagers at schools. Healthy eating messages for adolescents need to be developed and incorporated into existing and future campaigns to reinforce the perception that there are other healthier drinks that quench thirst and that taste good as well.

TL;DR: Research needs to include development of well-specified and robust research measures and methodologies; ongoing national surveillance of the sexual content of media and the exposure of various demographic subgroups of adolescents to that content; and longitudinal studies of the effects of that exposure on the sexual decision-making, attitudes, and behaviors of those subgroups.
Abstract: Background. Adolescents in the United States are engaging in sexual activity at early ages and with multiple partners. The mass media have been shown to affect a broad range of adolescent health-related attitudes and behaviors including violence, eating disorders, and tobacco and alcohol use. One largely unexplored factor that may contribute to adolescents' sexual activity is their exposure to mass media. Objective. We sought to determine of what is and is not known on a scientific basis of the effects of mass media on adolescent sexual attitudes and behaviors. Method. We performed an extensive, systematic review of the relevant biomedical and social science literature and other sources on the sexual content of various mass media, the exposure of adolescents to that media, the effects of that exposure on the adolescents' sexual attitudes and behaviors, and ways to mitigate those effects. Inclusion criteria were: published in 1983–2004, inclusive; published in English; peer-reviewed (for effects) or otherwise authoritative (for content and exposure); and a study population of American adolescents 11 to 19 years old or comparable groups in other postindustrial English-speaking countries. Excluded from the study were populations drawn from college students. Results. Although television is subject to ongoing tracking of its sexual content, other media are terra incognita. Data regarding adolescent exposure to various media are, for the most part, severely dated. Few studies have examined the effects of mass media on adolescent sexual attitudes and behaviors: only 12 of 2522 research-related documents (<1%) involving media and youth addressed effects, 10 of which were peer reviewed. None can serve as the grounding for evidence-based public policy. These studies are limited in their generalizability by their cross-sectional study designs, limited sampling designs, and small sample sizes. In addition, we do not know the long-term effectiveness of various social-cultural, technologic, and media approaches to minimizing that exposure (eg, V-Chips on television, Internet-filtering-software, parental supervision, rating systems) or minimizing the effects of that exposure (eg, media-literacy programs). Conclusions. Research needs to include development of well-specified and robust research measures and methodologies; ongoing national surveillance of the sexual content of media and the exposure of various demographic subgroups of adolescents to that content; and longitudinal studies of the effects of that exposure on the sexual decision-making, attitudes, and behaviors of those subgroups. Additional specific research foci involve the success of various types of controls in limiting exposure and the mitigative effects of, for example, parental influence and best-practice media-literacy programs.

TL;DR: This article identified factors that influence regular soda consumption among 564 male students, aged 13-18 years, attending North Los Angeles County public high schools and found that attitude, subjective norm and perceived behavioral control were significant predictors of intention to drink regular soda and together explained 61% of its variance.
Abstract: This study identified factors that influence regular soda consumption among 564 male students, aged 13-18 years, attending North Los Angeles County public high schools. Participants completed a group-administered Theory of Planned Behavior based questionnaire. Almost all of the participants, 96.5%, reported that they currently drink soda, 60.2% reported drinking two glasses of soda or more per day during the past year. Students reported drinking regular soda more than diet soda and reported drinking phosphoric acid containing soda (cola) more than nonphosphoric acid containing soda (noncola). Attitude, subjective norm, and perceived behavioral control were significant predictors of intention to drink regular soda and together explained 61% of its variance. Our results suggest that parents, teachers/coaches, and health professionals should encourage the perception that there are other healthier drinks that quench thirst better than soft drinks and taste good, and that soda should not be excessively available at home.
