You eat “like a girl”: gender differences in content and effects of food advertising depicting sports

Research to date is just beginning to examine the nature and impact of portrayals of physical activity on children’s attitudes in the marketing literature. The following two-part study therefore examines gender differences in the content and effects of food advertising depicting physical activities among children. Study one presents a content analysis of food advertisements shown during children’s television programming, revealing that healthy foods are associated with females while healthy activities are associated predominantly with males. Study two then examines children’s responses to an advertisement for an unhealthy food that portrays both male and female characters engaged in physical activities. Gender differences appeared to be the result of males’ greater belief that a junk food can aid in one’s physical abilities, leading them to hold greater intentions to engage in physical activity as compared to females and males who viewed an ad without physical activity.     

Healthy food, unhealthy food and obesity

We examine whether the latent behavioral mechanisms embedded in two “price effects” explanations of the obesity problem are operative. Our findings lend support to the hypothesis that falling food price is one likely cause of the obesity epidemic.     

Improving the food environment in kindergartens and schools: An overview of policies and policy opportunities in Europe

Childhood obesity and unhealthy nutrition are high on the European policy agenda because of their association with chronic diseases and due to the related social and economic burden. In 2014, the EU Action Plan on Childhood Obesity 2014–2020 was launched with an overarching goal to halt the rise of overweight and obesity in children by the year 2020. To facilitate the implementation of the Action Plan, the Directorate-General for Health and Food Safety of the European Commission provided support to bring together 25 Member States plus Norway for a Joint Action on Nutrition and Physical Activity (JANPA). The current paper is based on the results of JANPA and presents the explored policy options to improve children's nutrition by targeting the food environment in and around kindergartens and schools. We conclude that for effective actions countries need to combine various mutually reinforcing policies in parallel, including the provision of healthy foods, lowering the availability of unhealthy foods, restricting marketing, and promoting education. Success will depend on the coherence of messages and on the engagement of a wide range of stakeholders and sectors. Evaluation should be carefully designed, using indicators of progress towards the goal of improving diet and reducing obesity in children.

Comparing adolescent-focused obesity prevention and reduction messages

Drug abuse, smoking, and disordered eating literature reveal that some health promoting messages can induce unintended or harmful effects on the target audience. Scholars recommend careful messaging in social marketing campaigns, by shifting the focus away from health outcomes. This study tests the effects of adolescent-targeted obesity prevention messages (body-image, health benefit) with positive experience and unrelated messages on health behavior intentions and unintended effects. A pre-post experiment (N = 95) reveals that body-image public service advertisements (PSAs) may increase anxiety when compared to unrelated PSAs (no main effect, significant planned comparisons are found). Health benefit PSAs are more readable (F = 4.59, p < .05) than all other PSA groups and show higher healthy eating planning (F = 3.19, p < .05) compared to unrelated ones. No significant weight attitudes, self-esteem, and stages of change differences are found by message type. Overall, health benefit messages are not less effective.     

Farm subsidies and obesity in the United States: National evidence and international comparisons

Many commentators have claimed that farm subsidies have contributed significantly to the “obesity epidemic” by making fattening foods relatively cheap and abundant. But U.S. farm policies have generally small and mixed effects on farm commodity prices, which in turn have even smaller and still mixed effects on the relative prices of more- and less-fattening foods. Other factors have had much more influence on reducing the farm prices of food commodities and the consumer prices of food such that any effects of U.S. farm policies on U.S. obesity patterns must have been negligible. Moreover, while many arguments can be made for changing U.S. farm subsidies, even entirely eliminating the current programs could not be expected to have a significant influence on obesity rates. International evidence reinforces this finding. The countries that support their farmers most strongly tend to have relatively low obesity rates. In these countries the main support for farmers comes through trade barriers and higher consumer prices, which—like U.S. policies for sugar, dairy, orange juice, and beef—discourage consumption and reduce obesity. In contrast with agricultural subsidies, agricultural R&D has had a significant effect in the past on the relative price of food commodities and food, and has the potential to influence obesity patterns in the future, but R&D policy is a very blunt instrument for pursuing public health policy objectives.     

Incentive contract design for food retailers to reduce food deserts in the US

In the US, obesity affects over 37% of the adult population and over 16% of the child and adolescent population. Although not-for-profit agencies cannot directly control what a person eats, they can influence the supply side of the obesity epidemic by incentivizing food retailers to open stores in regions of the US where food deserts exist. An incentive contract design dependent upon performance and resulting health benefit is presented for food retailers to reduce food deserts in the US. A principal-agent framework is used to capture the competing interests and moral hazard from the contracting mechanism. Optimization models are developed to determine the most effective and equitable resource allocations from the initiative given a target reduction in obesity rate or a set budget, while determining the optimal subsidy these agencies should offer to food retailers to incentivize operation in certain counties. These subsidies are designed to create financially viable conditions for food retailers to offer high quality, healthy food alternatives. The impact of retailer location on obesity is based on estimates of marginal effect on obesity rate. Given an example initiative in metropolitan Atlanta, Georgia and surrounding counties, the overall county-wide obesity rate would decrease by 1.17% with a fixed budget of $400M. Sensitivity analysis on the reduction in obesity is performed for varying total budget amounts. This incentive contract design strategy is a positive step toward ensuring that the underserved US population has better access to healthy foods while helping solve the obesity epidemic.     

THE CAUSAL LINK BETWEEN FINANCIAL INCENTIVES AND WEIGHT LOSS: AN EVIDENCE‐BASED SURVEY OF THE LITERATURE

Obesity and overweight are linked to diseases that cost society a significant amount of resources. While behavior modification can reduce the problem, instigating such lifestyle changes is an uneasy task. One potential way to reduce the problem is through the use of financial incentives. In this survey, we review the available evidence, properly emphasizing studies that credibly yield meaningful estimates of the effect of financial incentives on weight loss. We find that the scientific literature on the subject has not yet satisfactorily settled whether such a mechanism is effective at eliciting the desired behavioral and health outcomes. We therefore advocate a rigorous large‐scale randomized experiment to provide reliable estimates of the effect.     

Neighborhood socioeconomics,food environment and land use determinants of public health: Isolating the relative importance for essential policy insights

Recent literature has advocated the connection between land use policies with public health promotion. In this regard, examining the land use determinants of public health and isolating the relative importance with other influential factors should provide essential policy insights. However, very limited efforts have been made in this aspect, particularly for the developing countries. Using a case of Wuhan (China), this paper attempts to capture the land use determinants of obesity prevalence among middle-aged adults and to compare the relative importance with neighborhood socioeconomics and food environment. A conceptual framework is first proposed to guide the analysis within a land use policy context. Data are then collected during the China’s National Physical Fitness Survey in 2010 and multivariate linear regression is applied to analyze the district level determinants. Results show that neighborhood socioeconomics, food environment and land use all have significant effects on obesity prevalence among the middle-aged adults. The men obesity is associated with the occupation, education and housing, while women obesity is correlated with income and housing. Women obesity associates with healthy food environment, while men obesity correlates with unhealthy food environment. Open public space is negative to women obesity, and institutional land is negative to men obesity. Greater walkability and street connectivity associate with lower obesity risk for both genders. The variance decomposition demonstrates that food environment is the most important determinant of men obesity, while land use is the most essential determinant of women obesity. For the obesity prevalence among total population, neighborhood socioeconomics are key determinants. Based on our analysis, we finally provide some insights for land use policies that aim at addressing the obesity issue in developing countries.     

Does shelf space management intervention have an effect on calorie turnover at supermarkets?

Despite recognizing the potential of retail settings for interventions aimed at bringing the rate of obesity down, there have been few attempts to implement experimental studies aiming to increase consumption of healthy foods and decrease consumption of unhealthy foods in the retail setting. An experimental controlled trial has been conducted using 10 supermarkets in Denmark. The study looked specifically into the possible effect of shelf space management intervention at supermarkets. The study found a significant intervention effect for individual products targeted by the project. But overall, care is needed to interpret results on aggregate level since statistical findings do not support category wide effect of shelf space intervention.
