Child obesity: what can be done and who will do it?

Among the measures recommended by the WHO to reduce the risk of obesity and non-communicable disease, the consumption of a diet rich in micronutrients but with a relatively-low energy density features prominently. However, only a small percentage of the UK population (<1) appears to be consuming the recommended diet. Dietary behaviour is strongly influenced by the dietary environment, shaped by food supplies, investment policies and advertising, to create an obesogenic food market. Substantial resources have been invested in food production of a sort that does not promote better health; agriculture and food supply sectors have benefited from decades of public-sector support, but this practice has encouraged the production of meat, dairy, oils and sugar and the withdrawal from sale of fruit, vegetables and fish. The result is an 'obesogenic economy', i.e. a market economy that encourages weight gain, in which children are a prime target. Interventions in the obesogenic market need to be considered and several opportunities are described in the present paper. Recent moves to strengthen national and international food policies aimed to promote healthier behaviour have been undertaken, but they will need political support if they are to be fully implemented. Alliances of public health interests can help to create that political support and promote health-enhancing environments.
