    Engaging adolescent males is a promising violence prevention strategy. This study explored primary versus secondary prevention effects of a gender-transformative program (i.e., Manhood 2.0) versus job-readiness training on multiple forms of violence perpetration. Adolescent males, ages 13 to 19 years, were recruited through youth-serving organizations in Pittsburgh, PA, between July 27, 2015, and June 5, 2017, to participate in an unblinded community-based cluster-randomized trial in 20 neighborhoods. The intervention curriculum, Manhood 2.0, focused on challenging norms that foster gender-based violence and building bystander skills. The control program was job-readiness training. We completed a planned secondary analysis of surveys from baseline and 9 months post intervention (follow-up), wherein we stratified participants based on any sexual violence/adolescent relationship abuse (SV/ARA) at baseline and examined risk of perpetration of SV/ARA, incapacitated sex, sexual harassment, cyber sexual abuse, peer violence, bullying, and homophobic teasing at follow-up. Among 866 participants, mean age was 15.6 years, 70% identified as Black, 6% as Hispanic, and 6% as multiracial. In both the Manhood 2.0 intervention group and job-readiness control groups, youth who reported SV/ARA at baseline were significantly more likely to report any form of SV/ARA, incapacitated sex, sexual harassment, cyber sexual abuse, bullying, and homophobic teasing at follow-up. Among participants who reported no SV/ARA perpetration at baseline, participating in the Manhood 2.0 intervention program was associated with increased risk of SV/ARA at follow-up compared to participating in the job-readiness control program. Among participants who reported SV/ARA perpetration at baseline, participating in the Manhood 2.0 intervention group was associated with lower risk of peer violence at follow-up. Synergizing gender-transformative approaches with job-readiness training may offer opportunities for crosscutting prevention programming to address multiple forms of violence.

    BACKGROUND: Smoking reduction remains a pivotal issue in public health policy, but quit rates obtained with traditional quit-smoking therapies remain disappointingly low. Tobacco Harm Reduction (THR), aiming at less harmful ways of consuming nicotine, may provide a more effective alternative. One promising candidate for THR are electronic cigarettes (e-cigs). The aim of this study was to investigate the efficacy of second-generation e-cigs both in terms of acute craving-reduction in the lab and in terms of smoking reduction and experienced benefits/complaints in an eight-month Randomized Controlled Trial (RCT).
    DESIGN: RCT with three arms.
    METHODS: Participants (N = 48) unwilling to quit smoking were randomized into two e-cig groups and one control group. During three lab sessions (over two months) participants, who had been abstinent for four hours, vaped/smoked for five minutes, after which we monitored the effect on craving and withdrawal symptoms. eCO and saliva cotinine levels were also measured. In between lab sessions, participants in the e-cig groups could use e-cigs or smoke ad libitum, whereas the control group could only smoke. After the lab sessions, the control group also received an e-cig. The RCT included several questionnaires, which repeatedly monitored the effect of ad libitum e-cig use on the use of tobacco cigarettes and the experienced benefits/complaints up to six months after the last lab session.
    RESULTS: From the first lab session on, e-cig use after four hours of abstinence resulted in a reduction in cigarette craving which was of the same magnitude as when a cigarette was smoked, while eCO was unaffected. After two months, we observed that 34% of the e-cig groups had stopped smoking tobacco cigarettes, versus 0% of the control group. After five months, the e-cig groups demonstrated a total quit-rate of 37%, whereas the control group showed a quit rate of 38% three months after initiating e-cig use. At the end of the eight-month study, 19% of the e-cig groups and 25% of the control group were totally abstinent from smoking, while an overall reduction of 60% in the number of cigarettes smoked per day was observed (compared to intake). eCO levels decreased, whereas cotinine levels were the same in all groups at each moment of measurement. Reported benefits far outweighed the reported complaints.
    CONCLUSION: In a series of controlled lab sessions with e-cig naïve tobacco smokers, second generation e-cigs were shown to be immediately and highly effective in reducing abstinence induced cigarette craving and withdrawal symptoms, while not resulting in increases in eCO. Remarkable (>50 pc) eight-month reductions in, or complete abstinence from tobacco smoking was achieved with the e-cig in almost half (44%) of the participants.
