Community-based, Controlled, Open-label, Cluster-randomized Trial for the Reduction of Chronic Malnutrition in Children Under Two Years of Age, With Three Intervention Arms Grouped by Clusters, in Two Provinces in Southern Angola, Huíla and Cunene.
Maternal and Child Interventions Against Chronic Malnutrition in Angola. A Cluster-randomized Cost-benefit Community-based Study.
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.

Arms and Interventions

---|---|
Active Comparator: Standard Intervention (CONTROL Arm)
The Standard package includes a series of actions carried out by the Community and Health Development Agents (ADECOS), who improves access to primary health care practices and promotes well-being behaviors at community levels. ADECOS has the potential to facilitate improvements in the health state and quality of life in rural communities. Activities performed by ADECOS can be grouped into two blocks:
|
The activities included are the following:
|
Experimental: Standard Intervention plus nutritional supplementation (CONTROL+NUT Arm)
In addition to the services performed by the ADECOS, it is included a supply of complementary food rations (individual + family) at the relative level, being:
|
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. |
Experimental: Standard Intervention plus money transfers (CONTROL+TM Arm)
In addition to the services performed by the ADECOS, it will be delivered a total of 14,000.00
Kz per month and per relative with 4 or more people living in the same household by the end of the study.
It will be delivered a total of 11,000.00
Kz per month and per relative with 3 or fewer people living in the same household by the end of the study.
The monetary value will be delivered in cash with unconditional format, and it will not be determined by the investigator team the use and the destination of said amount and nothing will be requested in return.
|
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.
