Introduction:

The increasing prevalence of obesity or overweight at all ages, their associated morbidity and mortality associated, and the increased perception of the problem by the society have generated several hypotheses in response to the scientific and the international community.

Objective:

Investigate the preventive interventions in childhood obesity so far.

Methods:

Integrative review during the study period from April 2013 to November 2014. The MEDLINE international database was used, including PubMed, the Cochrane Library (Issue 4 2002), the national database Isooc (CSIC) national database, as well as the Internet. The review included health articles published in Spanish and English between 1990 and 2014 that focused on or included education, prevention, diagnostic, and treatment of obesity interventions.

Results:

Of the 726 articles identified, 34 of most relevant (peer reviewed) were selected. It was noted that there is limited generalisable evidence on interventions that could be imple mented in Primary Care or referral services available, although numerous studies suggest that improvements in the overweight are possible.

Conclusions:

Despite the abundant literature and that many institutions place childhood obesity as one of the priorities of Public Health, we face the paradox that the evidence on cost-effectiveness of prevention interventions is sparse. Knowing these gaps in knowledge should lead to filling them with rigorous and well-designed studies.
