Development of severely malnourished children who received psychosocial stimulation: six-year follow-up
Insights
A home-visiting program of psychosocial stimulation helped severely malnourished children catch up developmentally. While some gains slightly declined after the program, children maintained significant advantages over those receiving standard care only.
Area of Science:
- Child Development
- Pediatric Nutrition
- Psychosocial Intervention
Background:
- Severe malnutrition significantly impacts child development, leading to developmental delays compared to well-nourished peers.
- Hospitalization for severe malnutrition necessitates interventions beyond standard medical care to address developmental deficits.
- Long-term developmental outcomes for malnourished children require ongoing assessment and support.
Purpose of the Study:
- To evaluate the long-term developmental impact of a home-visiting psychosocial stimulation program for severely malnourished children.
- To compare the developmental trajectories of malnourished children receiving psychosocial intervention versus standard care.
- To assess the sustainability of developmental gains after the cessation of the intervention.
Main Methods:
- A longitudinal study comparing three groups: malnourished children with psychosocial stimulation (n=16), malnourished children with standard care (n=18), and adequately nourished children (n=20).
- Regular assessments using the Griffiths Mental Development Scales and the Stanford-Binet intelligence test.
- Follow-up evaluations conducted during the third year of home-visiting and for three years post-intervention.
Main Results:
- The intervention group demonstrated catch-up development, reaching the level of adequately nourished children within two years.
- While some subscale scores declined post-intervention, the intervention group maintained a significant advantage on the Stanford-Binet test compared to the non-intervention malnourished group.
- Neither malnourished group achieved comparable height growth to the adequately nourished group throughout the study.
Conclusions:
- A simple home-visiting psychosocial stimulation intervention can significantly benefit the cognitive development of severely malnourished children.
- The positive effects of psychosocial stimulation on cognitive development can be sustained long-term, even after the intervention period.
- Nutritional rehabilitation alone is insufficient to fully address developmental deficits; targeted psychosocial interventions are crucial for improving developmental outcomes in malnourished children.
Abstract:
The development of 16 children who were hospitalized for severe malnutrition and participated in a home-visiting program of psychosocial stimulation was compared with that of two other groups who were also hospitalized but received standard medical care only: severely malnourished group (n = 18) and an adequately nourished one (n = 20). All groups were assessed regularly on the Griffiths Mental Development Scales and the Stanford-Binet test. Both groups of malnourished children were markedly behind the adequately nourished group on admission to the hospital and the group that received no intervention showed little sign of catching up. The intervention group caught up to the adequately nourished group in 2 years. This report covers the third year of home-visiting and the 3 years following its cessation. The intervention group showed a decline in three of the five Griffiths subscales. However, they retained a marked advantage over the nonintervention group of malnourished children on the Stanford-Binet test until the end of follow-up, showing no further decline in the last year. For height, both malnourished groups failed to catch up to the adequately nourished group. It was concluded that a relatively simple intervention can benefit the development of severely malnourished children.
