Brief Summary

This project is a delayed pragmatic delayed-intervention cluster randomized control study in a subset of households (n=600) enrolled in a larger scale up program of enhanced homestead food production (EHFP) in Cambodia. The trial is designed to evaluate the impact of EHFP (home gardens only; home garden and fishponds; home gardens and poultry) versus control group on dietary intake of women and youngest child, household food security, income, and production throughout the agricultural cycle. Following administration of the baseline survey 300 households will be randomized to the EHFP package of their choosing (Intervention Group) for two years. The other 300 households will not receive any intervention during the first year and will act as the control group; data will be collected monthly on production and income generated from gardening (and other homestead food production activities) and at two points throughout the year 24-hour dietary recall data will be collected from the women head of the household (aged 15-49y) and the youngest child between the ages of 6 - 59 months. After one year, the control group will be offered the intervention (EHFP package of their choice) fully subsidized and the project team will collect identical data on intervention group for one year as described for the control group.

Outcome Measures

Primary Outcomes (2)

• Difference in mean intake of zinc

  Sample size was calculated to detect a difference in zinc and vitamin A intake between any two groups, with 80% power and alpha of 0.05, assuming a 30% attrition. Measured by 24 hour dietary recall surveys with repeat recalls on a sub-set of the sample in order to adjust for intra-individual variations in intake and provide an estimate of usual intake.

  Measurements will be made for women of reproductive age and the youngest child in the household (> 6 mo < 60 mo) at baseline and ~ 7 months later

• Difference in mean intake of vitamin A

  Sample size was calculated to detect a difference in zinc and vitamin A intake between any two groups, with 80% power and alpha of 0.05, assuming a 30% attrition. Measured by 24 hour dietary recall surveys with repeat recalls on a sub-set of the sample in order to adjust for intra-individual variations in intake and provide an estimate of usual intake.

  Measurements will be made for women of reproductive age aand the youngest child in the household (> 6 mo < 60 mo) at baseline and ~ 7 months later

Secondary Outcomes (10)

• Household food security

  Baseline (2016) through to study completion, on average 2 years

• Women's empowerment / gender equity

  Baseline (2016) through to study completion, on average 2 years

• Incremental net monetary benefit

  Monthly for 1 year

• WASH practices

  Baseline (2016) through to study completion, on average 2 years

• Difference in mean energy intake

  Measurements will be made for women of reproductive age and the youngest child in the household (> 6 mo < 60 mo) at baseline and ~ 7 months later

Study Arms (2)

Control group

OTHER

For year one, this arm will receive no intervention. Usual agriculture production and income will be assessed monthly for one year. Additionally, every season (twice yearly), household food security and usual dietary intake of woman of reproductive age (WRA) and their child aged 6-59 mo will also be collected. After one year of implementation, this group will be offered the Enhanced Homestead Food Production package fully subsidized, as well as training on nutrition, WASH, gender and business/marketing.

Behavioral: Control group

EHFP group

EXPERIMENTAL

Households will receive training and inputs for an Enhanced Homestead Food Production (EHFP) package. Participants will also receive educational components through inter-personal behavioural change communication on nutrition (Essential Nutrition Actions), Water Sanitation and Hygiene (WASH), gender, and business/marketing.

Behavioral: EHFP group

Interventions

Control group BEHAVIORAL

A comparison group; no intervention for year 1, EHFP after 1 year of program implementation.

Control group

EHFP group BEHAVIORAL

Intervention group: training; inputs cost-sharing for EHFP activities.

EHFP group
