Clinical Trial Summary

Diet quality is generally poor in rural Nepal, especially among vulnerable household members. Consumption of milk (and other animal source foods [ASF]) could contribute to improvements in diet quality. However, multiple cultural, structural and economic barriers constrain the inclusion of ASF in the diet in these households, even though most raise dairy animals. This study will 1. characterize these barriers in detail 2. conduct a randomized controlled trial to test a multi-dimensional behavior change intervention designed to increase ASF/milk consumption by young children 6-60 months, adolescent girls 10-15 years, and women of child-bearing age (WCBA). Matched clusters of villages in Kapilbastu and Nawalparasi districts (Nepal) will be randomized to Intervention or Control status. Household surveys will be conducted at baseline and 12 months later to collect demographic, diet, feeding practices, nutrition knowledge, etc. Fathers and adolescent girls will respond to mini-surveys. Growth parameters of children, adolescent girls, and WCBA will be assessed. The intervention consists of 4 components: 1) didactic training (mothers, fathers, adolescent girls), 2) participatory learning activities (mothers, fathers, adolescent girls), 3) model kitchens (mothers, adolescent girls), and 4) Nutrition Club (adolescent girls). The primary outcome will be the impact of the intervention on diet, household feeding practices, and nutrition knowledge.

Description:

Animal-source-foods (ASF) contains nutrients essential to human health. These nutrients are especially important for vulnerable household members (young children, adolescent girls, women of child-bearing age [WCBA]). 1, 2 In developing countries, milk is generally one of the largest sources and most widely consumed animal-based dietary protein 3 Although livestock farmers are more likely than their counterparts to consume ASF 3-5, paradoxically, families that rely on agriculture and livestock production for their livelihoods are significantly food and nutrition insecure households. This is partly due to use of the income earned from livestock for purposes other than improving household diet diversity and quality, and partly due to inadequate knowledge about the importance of doing so. In addition, household food allocation practices and cultural beliefs and taboos impact ASF consumption by individual family members. ASF consumption in Nepal, for example, is often prioritized for the primary household bread winner (usually an adult male) 6. Thus, multiple cultural, structural and economic barriers converge to limit consumption of ASF by vulnerable household memb8rs. Many governmental and non-governmental organizations attempt to improve diet quality in rural households via nutrition education in hopes of motivating behavior change among participants. However, results of such programs have been inconsistent and generally disappointing 7-9. Even programs which provide a robust agricultural intervention are not always successful in improving diets or child growth 10, 11. Therefore, the study will define the barriers to household ASF consumption in rural Nepal and introduce a package of solutions to overcome these barriers. The design of the intervention builds on prior formative work 1, 12-20 21, and will be tested in a randomized controlled trial. While young children under 5 years of age remain a strong focus of this work, adolescent girls, WCBA and fathers will also be included in the intervention activities. This intervention addresses implementation gaps identified in the investigators' prior work and incorporates findings in recent literature regarding the effectiveness of specific behavior change interventions on nutrition outcomes 22. The investigators' previous work demonstrated that barriers to improving child nutrition are not overcome by increased income, nutrition education, or enhanced household milk production. Recent work has highlighted the value of specific components of behavior change programs: (1) demonstrations of how to perform the behavior, (2) cooking/recipe demonstrations, (3) restructuring the social environment (e.g., women's groups) and engaging with fathers and other groups not typically included, (4) providing households with prompts/cues, (5) action planning, goal-setting and problem-solving, (6) providing information about health consequences, (7) offering strategies to families to self-monitor behaviors. This planned multi-faceted intervention incorporates these elements to augment the effectiveness of behavior change messaging provided to household members, while strengthening community involvement, fostering sustainability and facilitating scaling-up activities.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Animal Source Foods Consumed in prior 24 hours (diet recall survey), baseline to endline	Impact of nutrition education on diet of mothers, children 6-60 months, and adolescent girls will compared between baseline and endline.	~1 year
Secondary	Change in height-for-age z score from baseline to endline for children 6-60 months	Child height in centimeters will be measured at baseline and endline. Results will be converted to z scores using World Health Organization standards. Changes in height-for-age z score between baseline and endline will be compared, and related to child consumption of animal source foods.	~1 year
Secondary	Change in head circumference-for-age z score from baseline to endline for children 6-60 months	Child head circumference in centimeters will be measured at baseline and endline. Results will be converted to z scores using World Health Organization standards. Changes in head circumference-for-age z score between baseline and endline will be compared, and related to child consumption of animal source foods.	~1 year
Secondary	Change in BMI from baseline to endline for adolescent girls	Height in centimeters and weight in kilograms will be measured in adolescent girls 10-15 years of age at baseline and endline. Results will be converted to BMI (kg/m^2) using World Health Organization standards. Changes in BMI between baseline and endline will be compared, and related to adolescent consumption of animal source foods.	~1 year
