Prevention of child obesity: 'first, do no harm'.

The prevalence of child obesity has steadily increased in Western and developing countries over the last two decades, and child obesity prevention is now firmly on the agendas of nearly all major governments. We are now confronted with the challenge of what to do about the problem, and the general consensus among various academics, researchers, practitioners and administrators worldwide is that prevention needs to begin. Before governments and other agencies leap into actions that they assume to be beneficial in the battle against child obesity, we must remember to employ one of the most important principles of modern medicine and prevention science, ‘First, do no harm’. An examination of potentially unhelpful or dangerous outcomes of child obesity prevention efforts is required before prevention activities begin. There are many examples of perfectly reasonable and wellintentioned health messages being partially misconstrued or misunderstood by members of the general public, resulting in the inadvertent production of undesirable effects in the implementation of supposedly health-promoting activities. The uptake of dieting and slimming among girls and young women is one example of a health message gone wrong. The moderate and sensible government dietary guideline of the late 1970s was taken up by the target audience who required it least—young women, who adhered to the ‘control your weight’ message most vehemently. The exponential rise in disordered eating that followed these early messages has left health educators with the huge challenge of normalizing body image and eating behavior among a large proportion of our young population. The government message to control weight within reasonable limits was clearly exploited by cigarette advertisers who utilized the belief that cigarette smoking could be an effective slimming agent. This is an example of a health-related message going astray. What we failed to achieve as health educators, was to clarify this situation, that yes, controlling your weight is important, but not at the expense of other health behaviors. Multi-national corporations and marketers of the 1950s to 1980s clearly delivered the ‘smoking is slimming message’ and this well entrenched way of thinking has placed current health educators in the uneasy predicament of having to encourage quitters to believe that the benefits of quitting despite the expected risk of weight gain outweigh the perceived benefits of slimness. A huge challenge indeed! Similarly, the early ‘control your weight’ messages of the past, and those of today, clearly identify people who were overweight as failures, deviants or moral outcasts who needed some sort of ‘treatment’, most of which, when undertaken by the overweight person, resulted in further failure, defeat and humiliation, leaving us with the current prevalence of obesity of today. Is our message to overweight people and obese children any different today? Are our current preventive strategies any different or any more likely to succeed?
