简要总结
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.
详细描述
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:

结局指标
主要结局
Change in child weight
时间窗: Change from baseline weight-for-age (WAZ) at 12 months
Child weight in kilograms. A weight-for-age Z score (WAZ), a measure of underweight, will be calculated using weight and date of birth.
Change in child height
时间窗: Change from baseline height-for-age (HAZ) at 12 months
Child height in centimeters. A height-for-age Z score (HAZ), a measure of stunting, using height and date of birth
Change in child fish foods intake
时间窗: Change from baseline fish foods intake at 12 months
Intake of fish foods assessed for children 6-60 months using a Kenya-specific semi-quantitative food frequency questionnaire (FFQ) that includes both 24-hour and 7-day recalls.
Change in fisheries yield
时间窗: Change from baseline fisheries yield at 12 months
Fisher's catch will be counted and weighed and identified at landing sites. Lengths of fish will be measured for a sub-sample of individuals (n=20). Monthly catch per unit effort (i.e. yield) will be calculated as the mean daily catch multiplied by the fishing days per month. Sustainable yields will be determined by comparing the initial yields versus the rate of change of yields for each landing site or Beach Management Unit (BMU).
次要结局
- Child Dietary Diversity(Baseline and months 6 and 12)
- Fisheries Earnings(Baseline, regular intervals (5-10 times per month) for 12 months)
- Child Diarrheal Morbidity(Baseline and months 6 and 12)
