The Happy Meal® Effect: the impact of toy premiums on healthy eating among children in Ontario, Canada.

OBJECTIVES: "Toy premiums", offered with McDonald's Happy Meals®, are a prominent form of food marketing directed at children. Two California jurisdictions recently implemented policies that only permit offering fast-food toy premiums with meals that meet certain nutritional criteria. The primary objective of the current study was to examine elements of this policy in a Canadian context and determine if children select healthier food products if toy premiums are only offered with healthier food options. The study also examined if the impact of restricting toy premiums to healthier foods varied by gender and age. METHODS: A between-groups experimental study was conducted with 337 children aged 6-12 years attending day camps in Ontario, Canada. Children were offered one of four McDonald's Happy Meals® as part of the camp lunch program: two "healthier" meals that met the nutritional criteria and two meals that did not. In the control condition, all four meals were offered with a toy premium. In the intervention condition, the toy was only offered with the two "healthier" meals. RESULTS: Children were significantly more likely to select the healthier meals when toys were only offered with meals that met nutritional criteria (OR=3.19, 95% CI: 1.89-5.40). The effect of pairing toys with healthier meals had a stronger effect on boys than girls (OR=1.90, 95% CI: 1.14-3.17). CONCLUSION: Policies that restrict toy premiums to food that meet nutritional criteria may promote healthier eating at fast-food restaurants.

Marijuana and tobacco use among young adults in Canada: are they smoking what we think they are smoking?

The authors characterized marijuana smoking among young adult Canadians, examined the co-morbidity of tobacco and marijuana use, and identified correlates associated with different marijuana use consumption patterns. Data were collected from 20,275 individuals as part of the 2004 Canadian Tobacco Use Monitoring Survey. Logistic regression models were conducted to examine characteristics associated with marijuana use behaviors among young adults (aged 15-24). Rates of marijuana use were highest among current smokers and lowest among never smokers. Marijuana use was more prevalent among males, young adults living in rural areas, and increased with age. Young adults who were still in school were more likely to have tried marijuana, although among those who had tried, young adults outside of school were more like to be heavy users. Males and those who first tried marijuana at an earlier age also reported more frequent marijuana use. These findings illustrate remarkably high rates of marijuana use and high co-morbidity of tobacco use among young adult Canadians. These findings suggest that future research should consider whether the increasing popularity of marijuana use among young adults represents a threat to the continuing decline in tobacco use among this population.
