Clinical Trial Summary

The severity of the stunting in the provinces of Huíla and Cunene, Angola, in children aged 6 to 59 months is considered to be very high, as defined by the World Health Organization (WHO) classification of 2018. Some of the strategies that present promising results in the fight against chronic malnutrition have been specific nutritional interventions and money transfers. Among these, those that have so far had a greater impact in reducing chronic malnutrition indicators are fortified foods and lipid-based nutrient supplementation in small amounts. The hypothesis of the study is that these interventions applied from pregnancy can significantly reduce chronic malnutrition, each of which may have different impacts. The study intends, therefore, to evaluate an intervention that aims to obtain the highest quality scientific evidence on the best package of sensitive and specific measures that reduce chronic malnutrition and mortality in children under 2 years of age, maintaining the fundamental premises of sustainability, cost-benefit ratio, and scalability for other regions of the country. To this end, it was designed a community trial randomized by clusters in which different strategies will be evaluated separately: - Standard Intervention (CONTROL Arm) The Standard package includes a series of actions carried out by Community and Health Development Agents (ADECOS), which are characterized by having demonstrated strong evidence of their effectiveness in the scientific literature, and are part of the WHO guidelines and national health guidelines in different countries, including Angola. - CONTROL+ NUT (Nutrients Arm): Standard Intervention plus nutritional supplementation - CONTROL+ TM (Money transfers Arm): Standard Intervention plus money transfers Study population: pregnant women with more than 16 years of age; however the target population of the interventions will be the household where the pregnant woman lives. The impacts of interventions on indicators of chronic malnutrition in children under 5 years of age belonging to the household will also be analyzed.

Study Design


Intervention

Dietary Supplement:
Nutritional Supplementation
The Small-quantity lipid-based nutrient supplementation (SQ-LNS) consists of micronutrients delivered in a lipid-based vehicle. All pregnant women (as of 12 weeks self-referred) within households who were randomly included in the study in the nutritional supplementation arm and their children as of 6 months of age will receive the SQ-LNS. ? Pregnant women: 20-g sachets, 20 g (1 sachet) dose per day. Nutritional composition and caloric intake. Total = 12/13 months approximately. ? Children from 6 months of age: 20-g sachets, 20 g (1 sachet) dose per day. Nutritional composition and caloric intake. Total = 18 months. The distribution will be made by ADECOS on a fortnightly basis. A family ration will be distributed: family supplementation is presented in a basket of locally produced basic foods that complement the usual diet. The caloric distribution of the basket will be 45% of cereals, 30% of pulses, and 25% in oil, and 1 kg of iodized salt.
Behavioral:
Money transfers
The distribution of the amounts will be made through the corresponding financial providers, together with the Municipal or Communal Administration authorities, the Assistants of Community Activities, the Investigator's personnel, and the ADECOS. The distribution frequency will be every 3 months until the end of the study.
Standard intervention
The activities included are the following: Community interventions against malnutrition and promotion of adequate nutrition: raise awareness of malnutrition and training mothers to recognize signs of malnutrition. Community interventions in promoting hygiene and proper sanitation: a) Promotion of Community-Led Total Sanitation approach (CLTS)strategy: community awareness of the entire population included in the cluster about the dangers of open defecation, and the direct link to malnutrition; b) Promotion of Baby-Wash strategy: to make the community aware of the problems and consequences of unsafe water consumption. Biannual supplementation with vitamin A for children from 6 to 24 months of age. Biannual deworming (albendazole/mebendazole) for children from 12 months to 24 months of age and pregnant women as of 2nd quarter. Malaria prophylaxis with sulfadoxine-pyrimethamine (SP) in pregnant women as of 13 weeks of pregnancy.

Outcome

Type Measure Description Time frame Safety issue
Primary ? Proportion of children with moderate an serious chronic malnutrition (indices below -2 and -3 Z- scores below the reference median) at 24 months of age in the provinces of Huíla and Cunene. Effectiveness of three interventions (standard care, money transfers, and nutritional supplements) to reduce chronic malnutrition in children under two years of age in the provinces of Huíla and Cunene by the proportion of children with different degrees of malnutrition. 24 months
Secondary ? Proportion of children under 5 years of age with moderate and severe chronic malnutrition (indices below -2 and -3 Z-scores below the reference median) at the beginning and end of the study in the provinces of Huíla and Cunene. Effectiveness of three interventions (standard care, money transfers, and nutritional supplements) individually to reduce chronic malnutrition in children under 5 years of age in the provinces of Huíla and Cunene will be assessed by measuring height/length per age score. 0-1 and 24 months
Secondary Mortality rate at 3, 6, 12, 18, and 24 months after enrollment in the study. Mortality will be assessed during all study at selected time frames 3, 6, 12, 18, and 24 months
Secondary Incidence rate in relevant comorbidities Incidence of malaria, pneumonia, diarrhea, and anemia (Hemoglobin < 12g/dL) in children up to 2 years of age in the provinces of Huíla and Cunene will be measured. 6, 12, 18, and 24 months
Secondary Increment of food diversity grade at the end of the study compared to baseline. Attitudes and eating habits of families in the provinces of Huíla and Cunene will be quantified. 0-1 and 24 months
Secondary Number of pre- and post-natal visits. Pre- and post-natal care indicators such as exclusive breastfeeding rate in children up to 6 months of age and low birth weight will be assessed 6 months
Secondary Cost-effectiveness incremental ratios (obtained dividing the incremental cost by the incremental benefit for health ). The cost-effectiveness of different interventions will be measured. 2 years
Secondary Proportion of children with moderate and severe chronic malnutrition (indices below -2 and -3 Z- scores below the reference median) at 3, 6, 12, 18, months of age in the provinces of Huíla and Cunene. Effectiveness of three interventions (standard care, money transfers, and nutritional supplements) to reduce chronic malnutrition in children under two years of age in the provinces of Huíla and Cunene by the proportion of children with different degrees of malnutrition. 3, 6, 12, 18 months
