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.

ReviewUniversal school-based mental health programmes in low- and middle-income countries: A systematic review and narrative synthesis.
Depression and anxiety pose a significant burden during adolescence, which may have consequences for adulthood and future generations. The mental health needs of children and adolescents in low- and middle-income countries are not adequately addressed due to a lack of availability and access to services, and limited intervention research in these contexts. Universal school-based interventions provide a unique and potentially scalable opportunity to prevent and address mental health concerns amongst children and adolescents in low- and middle-income countries. ⋯ Of the 12,478 articles identified, 12 studies met our inclusion criteria and were included in this review. The included studies report on a variety of interventions differing in approach, format and content. Given the small number of studies and concerns with study quality, we are unable to conclude that universal school-based interventions may reduce symptoms of anxiety and depression in children in low- and middle-income countries.

Comparative StudyA longitudinal study of psychological distress in the United States before and during the COVID-19 pandemic.
The COVID-19 pandemic has caused financial stress and disrupted daily life more quickly than any prior economic downturn and on a scale beyond any prior natural disaster. This study aimed to assess the impact of the pandemic on psychological distress and identify vulnerable groups using longitudinal data to account for pre-pandemic mental health status. Clinically significant psychological distress was assessed with the Kessler-6 in a national probability sample of adults in the United States at two time points, February 2019 (T1) and May 2020 (T2). ⋯ Increase in psychological distress above T1 was associated with gender, age, household income, and census region. Equal numbers of people experienced serious psychological distress in 30-days during the pandemic as did over an entire year prior to the pandemic. Mental health services and research efforts should be targeted to those with a history of mental health conditions and groups identified as at high risk for increases in distress above pre-pandemic levels.

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.
