Concerns have been expressed about using tools developed from the epidemiological literature to identify overweight and obesity risk where there are few effective evidence-based interventions for those affected. There is evidence that complex interventions targeting diet and feeding delivered to parents of infants <2 years old show some positive intervention effects on feeding practices and physical activity, although many of these interventions do not tackle the psycho-emotional aspects of feeding and are not underpinned by behavioural change theory. The impact on weight outcomes is less certain, and in some cases this may be due to intervention components and behaviour change techniques targeted at the parent rather than infant level. Universal eligibility for overweight and obesity prevention is costly and may be unnecessary for those with a low baseline risk. However, targeting of certain groups where overweight and obesity is more prevalent (for example, lower socio-economic status, minority ethnic groups) has raised concerns around stigmatisation. Preliminary work with parents/legal guardians/carers suggests that targeting may be appropriate provided the person conveying the information has appropriate knowledge and sensitivity. his suggests a novel approach to such discussions is needed. Digital technologies are being used to provide information to patients about health care related areas. The findings of a recent review suggest that interactive multimedia programmes have the capacity to facilitate communication between health professionals and patients, but further research in this field is needed.
