Malnutrition Clinical Trial

Official title: Livestock Programming for Nutritional Improvements in Pregnant, Lactating Mothers and Children Under Five Years of Age in Marsabit County, Kenya

Status Completed

Clinical Trial Summary

Children 5 years and below, and pregnant/lactating women in pastoralist communities suffer a high burden of acute malnutrition. Improving the health and productivity of animals can reduce the risk malnutrition during the dry periods. The aim of this study is to assess how providing livestock with feeds during critical dry periods can improve household milk availability, consumption and risk of malnutrition in pregnant and lactating mothers, and children 5 years and below. The study will be a cluster randomized control trial conducted in Marsabit County and will involve a total of 1800 households that own livestock and have children 5 years and below. The households will be divided into three groups and each group will have a total of 600 households. Group one, will receive livestock feed enough to maintain 2-3 milking animals during the critical dry period. The second group will receive similar livestock feed but will also receive education and counselling on human nutrition. The third group will be the control arm and will not receive any of the two interventions. The study will aim to estimate how these interventions impact stunting and underweight in children and weight gain for pregnant women by collecting data on middle upper arm circumference, height, weight, and weight-gain during pregnancy every three months in a year. In addition, data on food consumption patterns such as number of meals taken, type/diversity of foods consumed including animal source foods, frequency of times and quantity of specific foods consumed) on at least 6-weekly basis will be collected. To further understand this problem the investigators will collect human illness data including on fever, diarrhoea, and respiratory syndromes among study participants during the regular visits. Socio-economic data including household demographics, incomes, expenditures, asset accumulation, gender roles, and workload and time allocation will be collected quarterly. Biological samples will be collected (venous blood and mother's milk) at recruitment, six months and 12 months. Screening for infections such as brucellosis, micronutrient and mycotoxin analysis will be conducted on the biological samples in order account for infections or conditions that could have an impact on nutritional status of study participants. The study will also assess which of the interventions provide value for money given that resources are scarce.

Clinical Trial Description

Background: In households heavily dependent on livestock, declining availability of forage is associated with decreased consumption of animal source foods such as milk and meat, and consequently decline in child nutritional status. Populations living in Kenya's Arid and Semi-Arid Lands(ASALs) are predominantly pastoral, heavily dependent on livestock and practice seasonal mobility to access livestock pasture and water. Livestock interventions that maintain or improve health and productivity of animals have been postulated as important for reducing the risk of malnutrition during critical drought periods. Objectives: Here the investigators implement a cluster randomized control study trial to determine the effect of providing livestock feed, livestock feed and nutritional education and counselling during critical dry periods on household milk availability and consumption, and the risk of malnutrition in pregnant and lactating mothers, and children 5 years and below. Methods: A total of 1800 households owning livestock and with children 3 years and below in Marsabit County will be enrolled into three equal groups (arms) of 600 households each. Each household and participant will be followed for 18 months. Households in Arm 1 will receive livestock feed enough to maintain 2-3 milking animals during the critical dry period. Arm 2 will receive similar livestock feed and human nutritional education and counselling. Arm 3 (control arm) will not have any of the two interventions. Primary outcome measures will be child anthropometric indicators (height-for-age, weight-for-age and middle upper arm circumference) and maternal anthropometric measures (middle upper arm circumference, height, weight, weight-gain during pregnancy) collected quarterly. Data on a 24-hour recall of diet (number of meals taken, type/diversity of foods consumed including animal source foods, frequency of times and quantity of specific foods consumed) will be collected every 6 weeks. To control for additional factors that would influence nutritional status, the investigators will collect human health syndromic data (fever, diarrhoea, respiratory syndromes) and livestock health data every six weeks and socio-economic data quarterly including household demographics, incomes, expenditures, asset accumulation, gender roles, workload and time allocation. To control for exposure to infections such as brucellosis in humans and animals and for micronutrient and mycotoxin analysis, biological samples (venous blood of mother and child), animal biological samples (blood and milk) and household drinking water will be collected at recruitment, 6 months and at 12 months. The study will test the cost-effectiveness of livestock interventions and nutritional counselling in prevention of malnutrition and its health consequences, compared to treatment of malnutrition. Cost data associated with each study arm will be tracked to provide estimates of resources required to scale up for implementation. Results from this study will form the basis for monitoring efficiency and effectiveness of interventions aimed at reducing seasonal spikes in levels of acute malnutrition in children under five years and pregnant and lactating women in pastoralist communities. Study duration: Each study household and participant is followed for a period of 24 months from the time of enrolment into the study. ;
