Childhood obesity and the income gradient: evidence from Australia

This article examines the dynamic nature of human capital formation in the context of childhood obesity and the association of household income and childhood obesity in Australia using the first five waves of the Longitudinal Study of Australian Children. Our results show a strong evidence of dynamic nature of child obesity: the lag obesity is a significant and robust predictor of obesity in the current period. We also found that the main channel for childhood obesity is inter-generational trait: the probability of obesity in children born to an obese mother or father is 15% higher than that of other children. Other important determinants are lifestyle factors, including the consumption of drinks with a high sugar content and the amount of time watching TV. Income becomes an insignificant determinant of childhood obesity once we control for unobserved individual heterogeneity.     

Socio-economic analysis of U.K. home accidents

Abstract

Drowning is the third commonest cause of accidental death of children in the UK and many children drown in domestic swimming pools. Concern has been raised about the design and safety of the covers used on domestic swimming pools since the majority of drowning and near-drowning incidents occur in pools with covers on. Swimming pool covers are a diverse range of products and fulfil a number of functions. This diversity in their design and the associated hazards necessitated a multidisciplinary approach to their evaluation. A study of the epidemiology of drownings was carried out in order to specify the risks of swimming pool covers, together with a study of the market and a survey of pool owners and their attitudes to safety. The risks of swimming pool covers were then evaluated by engineering, materials and ergonomics testing which included simulation of both the user and the products. This study is an example of the need for a mix of test methods and types of simulations in order to provide an overall statement of the safety of some consumer products. Results showed that the floating, heat retaining covers used on the majority of UK domestic pools possibly add to the intrinsic risks of a swimming pool. Winter debris covers, although appearing to seal the pool and considered by the majority of owners to make pools safer, were shown to allow children relatively easy access under the cover.     

FAT TAXES AND OTHER INTERVENTIONS WON'T CURE OBESITY

Many countries are either introducing or proposing to introduce taxes on fat in foods as an attempt to curb growing rates of obesity. It is argued here that such taxes would be uneconomic, ineffective, discriminate racially, encourage rent‐seeking behaviour and result in various adverse unintended consequences.     

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.     

The Fight Against Obesity: Influences of Self-Efficacy on Exercise Regularity

Given the current social problem of obesity, past and current research efforts have examined consumer choice and decisionmaking regarding food consumption. However, preventative health behaviors such as exercise are also instrumental in combating the obesity epidemic. Limited studies in the marketing literature have explored how internal and psychological characteristics influence physical activity and exercise regularity. Thus, this study seeks to examine how individual self-efficacy impacts exercise behavior. Findings indicate that in order to fully explain the relationship between perceived self-efficacy and exercise regularity, significant mediating factors such as health consciousness, goal progress, attitude toward exercise, and satisfaction with current weight must be included in the decision-making process. Implications for consumers, social marketers, and public policy makers are discussed.     

Inversionary and Liminoidal Consumption: Gluttony on Holidays and Obesity

This study aims to explore gluttony as a liminoidal and inversionary form of behavior on all-inclusive holidays and its possible relationship with obesity. The study particularly looks at tourists’ attitudes toward food and drinks on all-inclusive holidays, that is, whether they consume food and drinks excessively on holidays; and if they do, whether their excessive eating and drinking habits are continued after their all-inclusive holidays. The findings suggest that people who go on all-inclusive holidays consume more food and drinks (both in terms quantity and variety) and a significant proportion of them, though to a varying extent, continue their excessive consumption habits after their holidays.     

Measuring the total impact of demographic and behavioural factors on the risk of obesity accounting for the depression status: a structural model approach using new BMI

Building upon previous studies that highlight considerable overlap in the influential factors of both obesity and depression, we employ a structural model to investigate the direct and indirect impacts of behavioural and demographic factors on obesity. We use new body mass index (BMI) to calculate the obesity status and find a significant relationship between an individual’s depression status and his/her obesity status. The results and simulations imply that demographic and behavioural factors can significantly influence the obesity status both directly and indirectly through their impact on depression. Therefore, this study suggests that models which do not account for these various pathways of influence are most likely misrepresenting the impact of these factors on obesity.     

Demand for carbonated soft drinks: implications for obesity policy

This article examines consumer choices of Carbonated Soft Drinks (CSDs) and their implications for obesity policy. Demand in relation to product and consumer heterogeneity is estimated via a random coefficients logit model (Berry et al., 1995) applied to quarterly scanner data for 26 brands in 20 US cities, involving 40?000 consumers. Counterfactual experiments show that caloric taxes could be effective in decreasing caloric CSD consumption though having little impact on obesity incidence.     

Early claiming of social security benefits and labour supply behaviour of older Americans

The labour supply incentives provided by the early retirement rules of the United States Social Security Old Age benefits program are of growing importance as the Normal Retirement Age (NRA) increases to 67 and the labour force participation of older Americans starts to increase. These incentives allow individuals who claim benefits before the NRA but continue to work, or return to the labour force, to increase their future rate of benefit pay by having benefits withheld. Since the adjustment of the benefit rate takes place only after the NRA is reached, benefits received before the NRA can become actuarially unfair for those who continue to work after claiming. Consistent with these incentives, estimates from bivariate models of the monthly labour force exit and claiming hazards using data from the Health and Retirement Study indicate that early claimers who do not withdraw from the labour force around the time they claim are increasingly likely to stay in the labour force.     

Dollars and pounds: the impact of family income on childhood weight

This article examines the impact of family income on childhood weight status for children in the United States using matched mother-child data from the National Longitudinal Survey of Youth (NLSY 79). Instrumental variable (IV) models, family Fixed Effects (FE) models and family Fixed Effects IV (FEIV) models are estimated in order to control for causality. The results suggest that although the prevalence of childhood obesity is higher in low-income families in the sample, family income might be acting primarily as a proxy for other unobserved characteristics that determine the child's weight status rather having a major direct causative role in determining the child's weight status.
