Nutrition and food behaviours of children and adolescents: a health promotion perspective

Poor nutrition and the rise in inequalities in diet and obesity during childhood and adolescence are of concern in Ireland and globally. Food insecurity among families is also on the rise and impacts children and youth beyond the effects of poverty alone. The social, structural and commercial determinants of health help to explain why dietary and health inequalities exist yet the solutions to such inequity have been slow, delayed and difficult to implement. This review takes a health promotion approach to the diet of children and adolescents, drawing on evidence in the Republic of Ireland and beyond to emphasize a need for supportive environments and health promoting public policy. Schools are a key setting to improve dietary habits and diet-related diseases. The impact of food environments on dietary habits both within and external to schools is clear with evidence supporting the implementation of universal school meal provision and the use of planning regulations to enable healthier environments. Evidence of how best to support children and adolescent's diet out-of-term time is needed, especially within the Irish context. There is a clear need for upstream measures to support healthy dietary habits such as legislation to enforce restrictions of food marketing to children and extension of taxation of foods. Children and adolescents have the right and capacity to be involved in changes needed to our food system so that the marketing, availability and affordability of healthy foods becomes the norm for children and adolescents.
