Most risk factors for smoking initiation were stable across age. Tobacco control interventions may be robust for risk factors across age groups and may not need adjustment. At all ages, interventions should focus on eliminating smoking in the social environment and on reducing the availability of tobacco products.

OBJECTIVES: This article presents the first study of the economic consequences of obesity and overweight in the Canadian province of Quebec. The article examines three types of direct costs: hospitalizations, medical visits and drug consumption; and one type of indirect cost: productivity loss due to disability.

Mission TNT.06 may encourage young smokers to misreport their smoking status and to marginalise classmates who smoke. These findings prompted recommendations to conduct more in-depth evaluation of the smoke-free class competition before widespread dissemination of the program across the province.

Over the last years, many actions have been implemented in the Canadian province of Quebec to prevent health issues related to diet, physical activity and obesity. As a new public health programme is being launched, the 'How can we do better?' project aimed to identify priority areas for further action. An exhaustive search led to identify 166 interventions rolled out in Quebec between 2006 and 2014. We compared it with evidence-based recommendations. Findings were challenged during a 2-d deliberative forum gathering 25 key stakeholders. At the crossroads of these analyses, 50 proposals emerged to sustain/bolster current efforts or to implement new initiatives. Specific improvements were recommended, e.g. about food supply quality monitoring, healthy food accessibility and affordability, physical activity promotion through land use policies, schools and childcare facilities retrofit and urban planning. Crosscutting proposals stress the importance to implement a new governmental prevention strategy and to reinforce evaluation at all levels. This call for action takes place at a critical period for political commitment and should be maintained until and after curbing the prevalence of obesity and related diseases. Although Quebec-focused, 'How can we do better?' project outcomes may be informative for other jurisdictions, and the methods may be inspiring for those interested in combining knowledge syntheses and deliberative processes to inform decision makers in a limited time frame.

Cet article analyse les politiques et mesures publiques mises en oeuvre depuis 2006 au Québec afin que l’aménagement du territoire devienne plus propice à l’adoption d’un mode de vie physiquement actif et d’une saine alimentation. L’analyse est fondée sur un inventaire et un codage caractérisant les mesures qui tentent de modifier l’environnement physique, pour influencer l’alimentation, l’utilisation du transport actif et public, de même que la pratique d’activités physiques diverses. Nous comparons ces mesures québécoises adoptées par les autorités locales, régionales et nationales aux recommandations scientifiques en promotion des saines habitudes de vie. Cette comparaison a été soumise à un processus délibératif incluant experts et parties prenantes. L’article présente des recommandations quant aux stratégies d’aménagement du territoire les plus prometteuses pour favoriser un mode de vie physiquement actif et une saine alimentation aux niveaux local, régional et national, ainsi que les implications que cela comporte sur le plan politique.This article analyzes public policies and measures implemented since 2006 in Quebec, and aimed at making land-use planning more favourable to a physically active lifestyle and a healthy diet. The analysis is based on an inventory and coding scheme characterizing measures used for targeting changes in the physical environment, to influence diet, active and public transportation and physical activity. We compare these measures adopted by local, regional and national authorities in Quebec with the international scientific recommendations on the promotion of healthy lifestyles. This comparison is subjected to a deliberative process involving experts and stakeholders. The article presents recommendations for the most promising land-use planning policies, promoting a physically active lifestyle and healthy eating habits at the local, regional and national levels
