Study Details

Study Description

Brief Summary

This pilot study aims to introduce three interventions directed toward mitigating anemia among women in Ghana, including: 1) multi-sectoral behavior change, 2) strengthening market engagement of fish processors, 3) improving fish smoking technology and practices. These interventions will be implemented among female fish processors, a population that represents a promising focal area for intervention within fisheries value chains, which have been identified as a uniquely promising sector for intervention to mitigate anemia among women. The investigators expect that the findings from this study will inform understanding of how best to design, implement, and evaluate interventions into fisheries and other animal-source food value chains in Ghana and across sub-Saharan Africa to address anemia and other nutritional and health concerns.

Detailed Description

Anemia among women of reproductive age remains an intractable public health problem in many low- and middle-income countries, especially in sub-Saharan Africa (SSA) where more than one-third of women of reproductive age are anemic. The complex etiology of anemia suggests the importance of designing interventions that address both nutritional deficiencies and environmental drivers of anemia risk. This proposed research builds on new knowledge generated from ongoing formative research by our investigator team aimed at understanding the potential for interventions into animal-source food (ASF) value chains to influence anemia among adolescent girls and women in Ghana. The investigators have identified fisheries value chains in Ghana as a uniquely promising sector for intervention to mitigate anemia among women. Specifically, our research indicates that fish processing is the most promising focal area for intervention within fisheries value chains to address anemia among women. Therefore, the overall research objective of this proposed research is to develop, adapt, and pilot test a set of interventions into fisheries value chains in Ghana aimed at mitigating anemia among women. Specifically, the investigators aim to: 1) define the scope, feasibility, and scalability of priority intervention strategies that have been identified through our ongoing formative research, 2) adapt the interventions to the proposed study contexts, and 3) design and pilot test specific implementation strategies, as well as a monitoring and evaluation (M&E) framework for assessing intervention delivery, uptake, impacts, and mechanisms of impact at multiple loci along hypothesized program impact pathways.

Our ongoing formative research and an extended consultation process with stakeholders and community participants have identified priority strategies for intervention within fisheries value chains in Ghana that are feasible, scalable, likely to reduce anemia through multiple mechanisms, and for which there is clear potential for sustainability of impact. The investigators expect that the pilot testing of these interventions and the associated M&E framework will directly inform the design, implementation and evaluation of a full randomized controlled trial (RCT) that will evaluate the effectiveness of these interventions on anemia mitigation among women in Ghana. As such, the design of this pilot research will mimic that of a RCT with three distinct treatments delivered to women in separate study arms, each arm reflecting the priority intervention strategies identified through our ongoing formative research:

  • Treatment Arm 1 (TA1): a multi-sectoral anemia behavior change intervention focused on promoting a diversity of anemia-mitigating behaviors including consumption of micronutrient-rich ASFs, malaria and soil-transmitted helminth control practices, and water, sanitation and hygiene best practices (TA1 is also a component of Treatment Arms 2 and 3);

  • Treatment Arm 2 (TA2): an intervention aimed at strengthening women fish processors' engagement with markets through a group-based microcredit scheme, providing entrepreneurship training, and facilitating enhanced access to market price information;

  • Treatment Arm 3 (TA3): an intervention introducing improved fish smoking technology and practices to women processors aimed both at improving earnings and reducing harmful occupational exposures associated with fish smoking.

The investigators will recruit a total of 120 total participants from 12 communites in two regions of Ghana that represent marine and fresh water small-scale fisheries systems. Participants will be recruited into a nine-month pilot intervention with data collection occurring at baseline prior to the start of the intervention, at the middle point of intervention implementation, and at endline immediately following completion of intervention implementation. The investigators will use survey-based instruments, direct observation, participant diaries, anthropometric and dietary assessment, occupational exposure assessment, as well as analysis of blood and stool specimens to evaluate changes in anemia, micronutrient status, inflammation and infection, as well as changes in participants' knowledge, attitudes, behaviors, and exposures that the investigators hypothesize are linked to intervention exposure. Such an analysis is critical for understanding the relative importance of different mechanisms of impact for each intervention. The investigators will further carry out qualitative, semi-structured interviews with study participants and project implementation staff to understand their perceptions of the interventions, factors that facilitated or prevented successful implementation and uptake of interventions, and their perceptions of positive and negative changes resulting from participation in the project. These insights will be important for addressing our proposed research questions related to defining the scope of the proposed interventions, and assessing the feasibility of intervention uptake and implementation. A final project assessment workshop will also be carried out to internally assess the strengths and limitations of the project's M&E framework.

Smoked fish value chains in Ghana have clear potential to influence anemia risk among women fish smokers via multiple, potentially interconnected and contradictory mechanisms. More broadly, these value chains also have significant potential to affect the nutrition and health status of coastal and lake communities and of consumers across the country whose diets are profoundly shaped by these value chains. The investigators expect that the findings of this research will significantly contribute to understanding how best to design, implement, and evaluate interventions into fisheries and other ASF value chains in Ghana and across SSA to address anemia and related nutrition and health concerns.

Study Design

Study Type:
Interventional
Actual Enrollment :
120 participants
Allocation:
Randomized
Intervention Model:
Parallel Assignment
Intervention Model Description:
Two communities in each of two study regions will be assigned to one of the three treatments (i.e., six communities in total per region). Assigning two communities to the same treatment in each region will allow us to assess differential intervention design and implementation needs for communities in similar geographic areas. Ten women in each community will be purposefully selected for participation to ensure intra-community variation on participant age, socioeconomic status, years of experience with fish smoking, and the scale of fish smoking enterprises. Across both regions, 120 women will be recruited from a total of 12 communities. While the interventions will be delivered to individual women, treatment assignment will be carried out at the community-level given the risk of sharing information and inputs within communities that could contaminate intervention exposure and bias observed treatment effects.Two communities in each of two study regions will be assigned to one of the three treatments (i.e., six communities in total per region).

Arms and Interventions

Arm Intervention/Treatment
Experimental: Multi-sectoral anemia behavior change

Address multiple behavioral determinants of anemia by promoting the identification, knowledge, valuation and practice of four behavioral domains: 1) consumption of micronutrient-rich animal-source foods; 2) malaria and soil-transmitted helminth infection control practices; 3) water, sanitation and hygiene (WASH) best practices; and 4) women's autonomy in decision-making and control of the use of earned income.

Behavioral: Mobile phone audio messaging
Audio messages will be "pushed" to participants' mobile phones twice weekly on a set schedule in discrete modules that include basic information related to each of the four behavioral domains followed by an integration of the information across behaviors through relatable, character-driven narratives that enable message recipients to engage with the content through a real-world context.

Behavioral: Peer-to-peer learning
Women participants in each community will meet twice monthly for peer-to-peer learning sessions to reinforce the content of audio messages. These sessions will further use women's empowerment approaches including critical examination of gender dynamics, and discussions of solutions for equitable decision-making and control of resources within households. These discussions will be facilitated with male household members and grandmothers in separate learning sessions that will be held three times throughout the intervention period.
Experimental: Strengthening market engagement of fish processors

Assist women in overcoming limited access to credit, inadequate storage facilities, and insufficient information about market prices, which constrain the timeliness and amount of market-ready product available for sale, through a three-pronged approach that includes: 1) a conditional cash transfer; 2) entrepreneurship training; and 3) enhanced access to market price information.

These discussions will be facilitated with male household members and grandmothers in separate learning sessions that will be held three times throughout the intervention period.

Behavioral: Conditional cash transfer
Participants will receive a conditional cash transfer to support their fish smoking business. The payment will be conditional on their participation in entrepreneurship trainings and the use of the investment into their fish smoking business.

Behavioral: Entrepreneurship training
Entrepreneurship training will focus on commonly lacking business knowledge, with an emphasis on establishing fundamental entrepreneurial skills (i.e., customer care, accounting), sound business management and decision-making, building strong and sustainable business relationships, and encouraging the use of loans for their intended purposes. This training will be introduced during the credit and savings group (CSG) meetings that will occur twice per month.

Behavioral: Market price information
Average market prices for fresh and processed fish at community, district, and regional markets will be disseminated via audio message calls (using Viamo's Infoline platform) to the mobile phones of women with the price information in their preferred language. These market prices will be collected twice weekly by Viamo field enumerators and sent to regional coordinators for validation. A second, independent validation will be carried out to ensure that there are no discrepancies.
Experimental: Improving fish smoking technology and practices

Introduce and promote a recently developed fish smoking oven known as the Ahotor, which was explicitly designed to reduce emission from biomass fuel combustion, decrease polycyclic aromatic hydrocarbon (PAH) levels of smoked fish, and increase fuel efficiency. Use of this oven will reduce workload, increase earnings, and reduce harmful occupational exposures. Introduction of this improved fish smoking oven will be combined with behavior change education focused on promoting optimal fish smoking and handling practices.

Behavioral: Mobile phone audio messaging
Audio messages will be "pushed" to participants' mobile phones twice weekly on a set schedule in discrete modules that include basic information related to each of the four behavioral domains followed by an integration of the information across behaviors through relatable, character-driven narratives that enable message recipients to engage with the content through a real-world context.

Behavioral: Peer-to-peer learning
Women participants in each community will meet twice monthly for peer-to-peer learning sessions to reinforce the content of audio messages. These sessions will further use women's empowerment approaches including critical examination of gender dynamics, and discussions of solutions for equitable decision-making and control of resources within households. These discussions will be facilitated with male household members and grandmothers in separate learning sessions that will be held three times throughout the intervention period.

Behavioral: Improved smoke ovens
Local private sector artisans will construct and serve as suppliers of the new ovens. The promotion, uptake and impact of these improved Ahotor ovens will be tested among study participants. Awareness-raising workshops held in each community will promote the Ahotor in concert with a public retrofitting of a Chorkor stove. Immediately following this event, one month later, and three months later, study participants will receive additional one-on-one counseling to provide further support on the proper use of the smoke oven, as well as on optimal handling and smoking practices to enhance product quality.
