Insights
Child stunting, affecting 165 million children, stems from poor nutrition and infections during the critical 6-24 month complementary feeding period. Addressing this requires understanding broader societal factors influencing infant feeding practices.
Area of Science:
- Public Health
- Pediatrics
- Nutrition Science
Background:
- Child stunting affects 165 million children globally, with severe consequences.
- The complementary feeding period (6-24 months) is critical for development and sensitive to stunting.
- Stunting results from a complex interplay of poor nutrition, infection, and inadequate stimulation.
Purpose of the Study:
- To present a conceptual framework on stunting.
- To highlight the role of complementary feeding in child development.
- To identify contextual and causal factors influencing stunting.
Main Methods:
- Literature review and conceptual framework development.
- Analysis of contextual determinants of stunting.
- Synthesis of factors influencing infant and young child feeding practices.
Main Results:
- A framework is presented linking complementary feeding to stunting.
- Contextual factors include political economy, health systems, education, socio-culture, food systems, and environment.
- Infant feeding practices are influenced by societal conditions, impacting growth.
Conclusions:
- Effective stunting prevention requires addressing multi-level contextual factors.
- Interventions must consider proximal and distal determinants of child growth.
- Transdisciplinary research and policy informed by comprehensive assessments are crucial.
Abstract:
An estimated 165 million children are stunted due to the combined effects of poor nutrition, repeated infection and inadequate psychosocial stimulation. The complementary feeding period, generally corresponding to age 6-24 months, represents an important period of sensitivity to stunting with lifelong, possibly irrevocable consequences. Interventions to improve complementary feeding practices or the nutritional quality of complementary foods must take into consideration the contextual as well as proximal determinants of stunting. This review presents a conceptual framework that highlights the role of complementary feeding within the layers of contextual and causal factors that lead to stunted growth and development and the resulting short- and long-term consequences. Contextual factors are organized into the following groups: political economy; health and health care systems; education; society and culture; agriculture and food systems; and water, sanitation and environment. We argue that these community and societal conditions underlie infant and young child feeding practices, which are a central pillar to healthy growth and development, and can serve to either impede or enable progress. Effectiveness studies with a strong process evaluation component are needed to identify transdisciplinary solutions. Programme and policy interventions aimed at preventing stunting should be informed by careful assessment of these factors at all levels.
