Systematic reviews on infant and child feeding practices to prevent overweight and obesity and other risk factors for noncommunicable diseases in children and adolescents
Call for authors and review teams
Malnutrition, in all its forms presents significant threats to human health. Undernutrition contributes to about one third of all child deaths. Globally, an estimated 43 million children under-five years of age, or 7%, were overweight (i.e., weight-for-height above +2SD) in 2011 — a 54% increase from an estimated 28 million in 1990.
Increasing trends in child overweight have been noted in all regions. The prevalence of obesity in children is increasing in all regions of the world, including countries that suffer high levels of maternal and child undernutrition. Overweight and obese children are at higher risk of developing serious health problems including type 2 diabetes, high blood pressure, asthma and other respiratory problems, sleep disorders and liver disease.
They may also suffer from psychological effects, such as low self-esteem, depression and social isolation. Childhood obesity also increases the risk of obesity, noncommunicable diseases, premature death and disability in adulthood. In 2012, the World Health Organization (WHO)'s Member States endorsed six global targets for improving maternal, infant and young child nutrition and are committed to monitoring progress. The global targets are vital for identifying priority areas for action and catalysing global change.
The targets for 2025 include: reduction of childhood stunting, reduction of anaemia in women of reproductive age, reduction of low birth weight; no increase in childhood overweight, increasing exclusive breastfeeding rates in the first six months of life, and reduction of wasting in children.
The Departments of Maternal, Newborn, Child and Adolescent Health (MCA), and Nutrition for Health and Development (NHD) in collaboration with the Department of Prevention of Noncommunicable Disease (PND) are in a process of developing various guidance on the prevention and control of childhood obesity. As part of this effort, we are currently revising the recommendations for feeding infants and children to prevent obesity and other risk factors for noncommunicable diseases in children and adolescents . In March 2013 a consultation was convened in Geneva, Switzerland to review available research and epidemiological data on priority questions for recommendations in this topic.
As a follow-up, WHO is plans to develop comprehensive guidelines for preventing obesity and other risk factors for noncommunicable diseases in children and adolescents. A first step in this process is to review current WHO recommendations on infant and child feeding. To inform the guideline development process, WHO will commission several systematic reviews to retrieve, synthesise and assess the available evidence. A guideline review meeting is planned for November 2014.
- 28 March 2014 - Interested authors or teams submit concept notes and budget
- 18 April 2014 - WHO review of proposals complete and contact authors and review teams
- 2 May 2014 - Contracts agreed (subject to WHO conditions including review of declarations of interest of members of the systematic review teams)
- 19 September 2014 - Draft systematic reviews (for questions 1-6 listed at the end) submitted
- 17 October 2014 - Final systematic reviews with GRADE tables submitted
Qualifications of the author(s) / review team
- Interested author(s)/teams must have experience with conducting complex systematic reviews and should provide references of systematic reviews that they have published in peer-review journals
- Interested author(s)/teams should have members with complementary skills and competencies including knowledge of the technical area, statistical analysis and excellent writing capabilities.
Concept proposal and budget
Interested author(s)/teams are invited to submit a concept note (2-3 pages) outlining:
- The principal investigator and host institution with overall responsibility for the review.
- The questions that the author(s)/review team will address through systematic reviews. Author(s)/teams may undertake one or more reviews. However, they need to demonstrate capacity to conduct the review(s) within the timeline above.
- Questions #1-6 will be addressed in the review process and timelines outlined above. Questions #7-8 will be addressed in a second round of systematic reviews.
- The databases and process for review that the author(s)/teams would undertake and should reflect the scope of work described below.
- The competencies and specific contributions of the author(s)/teams who would undertake the review.
- Budget (US $). This should outline the total amount for the review including an approximate breakdown of personnel vs. institutional/other costs.
It is expected that WHO will provide technical input on the final protocols that will govern the systematic reviews. For the purpose of the concept note, it is not necessary to describe every detail of the systematic review.
