Abstract

Objective: To describe the change of nutritional status in children under 24 months of
age in 3 Northern mountainous provinces through the local production and marketing
model of complementary foods. Methods: A semi-experimental community intervention
study without a control group through 2 independent cross-sectional investigations
before the intervention (n=799) and after 6 months of the intervention (n=680) in over
680 children under 24 months of age have enough assessment before and after 6 months
of intervention in 3 provinces of Lai Chau, Lao Cai and Ha Giang. Interventions include
social marketing of locally produced micronutrient supplements and nutritional counseling
on the basis of the Baby Sun system. Results: After the intervention, there was a
statistically significant change (p<0.01) Z-Score of weight for age (increased from -0.93
to -0.73) and Z-Score of weight for each dimension. high (up from -0.41 to -0.16). The
rate of malnutrition in children under 2 years old tends to decrease (p > 0.05) after the intervention:
underweight decreased from 15.0% to 12.3%; stunting decreased from 24.0%
to 23.2%; emaciation decreased from 8.8% to 7.7%. Conclusion: The initial intervention
model showed an increase in weight-for-age and weight-for-height Z-Score, but there
was no clear change in the malnutrition status of children under 24 months of age in the
study area.
