ReviewCognitions and behaviours of general practitioners in France regarding HPV vaccination: A theory-based systematic review.
Human papillomavirus (HPV) vaccination is safe and efficacious to prevent persistent HPV infection, precancerous anogenital lesions and cervical cancer. However, in countries where vaccination programmes are implemented outside of schools, such as France, reaching high HPV vaccination coverage of the target population is challenging. Many studies have been performed in France to assess cognitions of general practitioners (GPs) regarding HPV vaccination. ⋯ GPs' injunctive norms, i.e. trust in institutional information, were shown to be associated positively with GPs' willingness to recommend HPV vaccination. Parents' fears, girls' age, and potential connection with sexuality do not seem to affect GPs' recommendations. These results will inform the development of a professional educational intervention targeting GPs in France.

The prospective association between illicit drug use and nonprescription opioid use among vulnerable adolescents.
In recent years, more than half of all drug overdose deaths in United States involved an opioid. To address this epidemic, antecedents to opioid misuse must be identified and empirically validated. The objective of the current investigation was to examine whether illicit drug use was prospectively associated with nonprescription opioid use among adolescents from a vulnerable population with a greater prevalence of substance abuse. ⋯ Multilevel, covariate-adjusted logistic regression models indicated that the odds of experimentation with nonprescription opioids was greater among adolescents who had used illicit drugs or illicit drugs excluding marijuana. Nonmedical marijuana use alone was a statistically significant predictor in unadjusted but not covariate-adjusted models. While prior studies have examined the progression from nicotine, alcohol, and marijuana use to nonprescription opioid use, the present findings emphasize the importance of illicit drug use as a detectable and empirically supported risk factor for future opioid misuse.

The bidirectional association between sleep and physical activity: A 6.9 years longitudinal analysis of 38,601 UK Biobank participants.
Although physical activity and sleep may influence each other, little is known about the bidirectional association of these two behaviors. The present analyses included 38,601 UK Biobank participants (51% female, 55.7 ± 7.6 years old, 6.9 ± 2.2 years of follow-up). Physical activity was categorized by the weekly metabolic equivalent of task minutes (highly active: ≥ 1200; active: 600 to <1200; inactive: < 600), and sleep patterns were determined using a composite score of healthy sleep characteristics: morning chronotype, adequate sleep duration (7-8 h/d), never or rare insomnia, never or rare snoring, and infrequent daytime sleepiness. ⋯ Compared to individuals highly active at both time points, being physically inactive at baseline and reducing physical activity over time were both associated with higher odds for poor sleep at follow-up. In conclusion, sleep improvements over time benefitted physical activity at follow-up, while reduced physical activity had a detrimental effect on sleep patterns at follow-up. Our results provide scope for interventions to concurrently target physical activity and sleep.

ReviewCharacteristics and impact of theory of planned behavior interventions on smoking behavior: A systematic review of the literature.
Theoretical frameworks such as the theory of planned behavior (TPB) can be applied to design and evaluate smoking behavior interventions. The present systematic review aimed to: (i) determine the characteristics of TPB-based interventions and their reported impact on smoking behavior and TPB variables, (ii) evaluate the level of methodological quality in the included studies, and (iii) assess the quality of the theoretical implementation. Studies were eligible for inclusion if the intervention targeted smoking behavior, was explicitly based on the TPB, and if smoking behavior or intention was measured at least at post-intervention. ⋯ Regarding methodological quality, unclear or high risks of bias were notably found regarding the selection of participants, data collection methods, withdrawal and drop-outs, and blinding. Regarding theoretical implementation, the reciprocal link between intervention techniques and TPB variables targeted remain unclear for a majority of studies. To better inform tobacco prevention and TPB research, future studies should more systematically use rigorous methods when designing, implementing, and reporting TPB-based interventions.

Review Meta AnalysisObjectively measured physical activity and all cause mortality: A systematic review and meta-analysis.
Current physical activity recommendations have been based on evidence from systematic reviews of questionnaire-based data. Questionnaire-based physical activity data are subject to both random and non-random error. If the estimated association between physical activity and health outcomes was different when a more accurate, objective measure was used, this would have important health policy implications for physical activity. ⋯ Individuals in the highest category of light, moderate-to-vigorous, and total physical activity had 40% (95%CI 20% to 55%), 56% (95%CI 41% to 67%), and 67% (95%CI 57% to 75%), respectively, lower risk for mortality compared to individuals in the lowest category of light, moderate-to-vigorous, and total physical activity. The summary hazard ratio for objectively measured physical activity and all cause mortality is lower than previously estimated from questionnaire based studies. Current recommendations for physical activity that are based on subjective measurement may underestimate the true reduction in mortality risk associated with physical activity.
