For the first time, Chang and Nayga looked at the relationship between unhealthy dietary habits and children’s psychological health. In particular, they studied the effects of fast food and soft drink consumption on children’s body weight and unhappiness. Using data from the National Health Interview Survey in Taiwan - a nationwide survey carried out in 2001 – the authors looked at the fast food and soft drink consumption, body weight and level of happiness of 2,366 children aged between 2 and 12 years old. Fast food included French fries, pizza and hamburgers; soft drinks included soda and other sugar-sweetened beverages.
A quarter of the children in the survey sample were overweight or obese and approximately 19 percent sometimes or often felt unhappy, sad or depressed. The study’s key finding was that children who ate fast food and drank soft drinks were more likely to be overweight, but they were also less likely to be unhappy. The authors’ analysis also highlighted a number of factors influencing children’s body weight, eating patterns and happiness. For example, mothers’ consumption of fast food and soft drinks predicted her child’s eating habits. Those children who ate fast food were more likely to also consume soft drinks. Children from lower income households were more likely to have unhealthy dietary habits and be overweight or obese.
What is going on with this result? Is the relationship real? If so, in which direction does the arrow of causality flow?
Keep in mind this result is from Taiwan. Would it hold in Japan or Scotland or Greece?
