Clinical Trial Summary
The purpose of this study is to test the effectiveness of a bundled intervention to address
malnutrition and its intersections with nutrition security and fisheries sustainability in
Kilifi, Kenya.
Description:
One in five young children globally suffer the consequences of stunted growth and
development, while millions experience deficiencies in zinc, iron, iodine, vitamins A and
B12, nutrients found bioavailable in fish foods. Small-scale fisheries (SSF) have the
potential to generate wealth and augment fish consumption while being environmentally
sustainable if appropriate systems are in place. However, those engaged in SSF are often
marginalized by large industrial fisheries and other factors. Coastal communities in Kenya
are dominated by SSF and are among the poorest and most malnourished globally. To address
these critical issues, investigators aim to test the effectiveness of a bundled intervention
to address malnutrition and its intersections with nutrition security and fisheries
sustainability.
A matched intervention/control study will be conducted to examine the multifaceted Samaki
Salama ("fish security" in Kiswahili) intervention in Kilifi, Kenya. The matched communities
will be divided into three groups: (1) control; (2) multi-tiered nutrition social marketing
intervention to fishers, mothers, and health workers; (3) multi-tiered nutrition social
marketing intervention plus fisher gear modification and training.
A total of 8 communities will be matched based on based on location (rural), livelihoods and
child nutritional status into control (n=4) and intervention (n=4) groups. Participants from
400 small-scale fisher households will be recruited and enrolled by Kenyan partners from
Egerton University and Pwani University using the eligibility criteria. Group 1 (n=200
households) will be the control group. Group 2 (n=100 households) will receive a multi-tiered
nutrition social marketing intervention focused on promoting dietary diversity and fish food
consumption specifically among infants, young children and women of reproductive age. The
nutrition intervention will target fishers, mother and health workers and involve monthly
communications of key nutrition messages across a range of platforms including mobile phone
messaging through WhatsApp or SMS, social media, radio, t-shirts, stickers, flyers, cooking
classes, meetings of mother's groups and other convening opportunities. Group 3 (n=100
households) will receive a bundled intervention of the multi-tiered nutrition social
marketing intervention plus fisher gear modification and training. Fishers from Group 3 will
receive modified fishing gear (traps) designed specifically to improve harvest efficiency and
promote sustainable fish populations. Training on modified gear use will be administered
through local fishing cooperatives.
Investigators hypothesize that the combined impact of the targeted social marketing and
fisher trap interventions will improve the diet, health and nutritional status of children as
well increase fisheries yield and fisher's earnings in intervention communities. Specific
hypotheses of primary and secondary outcomes are as follows:
Hypotheses: primary outcomes
- The children in the intervention groups (combined groups 2 and 3) with have increased
height-for-age Z score (HAZ) by 0.20 compared to children in the control (group 1).
- The children in the intervention groups (combined groups 2 and 3) with have increased
weight-for-age Z score (WAZ) by 0.10 compared to children in the control (group 1).
- The children in the intervention groups (combined groups 2 and 3) with have increased
fish food intakes by 100 g compared to children in the control (group 1).
- Fishers in the group 3 will have significantly increased fisheries yields of mature fish
compared to fishers in the control (group 1).
Hypotheses: secondary outcomes
- The children in the intervention groups (combined 2 and 3) with have increased dietary
diversity by 1.2 compared to children in the control (group 1).
- The children in the intervention groups (combined 2 and 3) with have reduced diarrheal
morbidity by 5 percentage points compared to children in the control (group 1).
- Fishers in group 3 will have significantly increased earnings compared to fishers in the
control (group 1).
