Prior studies explored the production and technical efficiency of fish farms and farmers from the perspectives of factors such as credit access and cooperative membership. We focused on the chronic non-communicable diseases (NCDs) of household members and their quantitative impacts on fish farm production efficiency, based on data of earthen pond fish farms from two regions (Bono East and Ashanti) in Ghana. A data envelopment analysis (DEA) and the IV Tobit technique were employed for the study's analysis. From the study's observations, we draw the following conclusions. We found that the NCDs of household members indeed reduce farm production efficiency, and the heterogeneous impact of the NCDs of female members on farm production efficiency was more prominent than that of male members. Insights from this study suggest that the national government should provide farmers with the necessary medical care through the provision of subsidized health insurance, which can facilitate access to healthcare services. Moreover, NGOs and governments should encourage health literacy, i.e., organizing programs aimed at educating farmers on NCDs and their impact on agriculture.
先前的研究从信贷获取和合作社成员资格等因素的角度探讨了鱼类养殖场和渔民的生产和技术效率。我们根据加纳两个地区（博诺东和阿散蒂）的土塘鱼类养殖场的数据，关注家庭成员的慢性非传染性疾病（NCDs）及其对鱼类养殖场生产效率的定量影响。该研究采用数据包络分析（DEA）和 IV 托宾技术进行分析。从研究观察中，我们得出以下结论。我们发现家庭成员的 NCDs 确实会降低农场的生产效率，而且女性成员的 NCDs 对农场生产效率的异质影响比男性成员更为突出。本研究的结果表明，国家政府应通过提供补贴性健康保险为农民提供必要的医疗服务，这有助于农民获得医疗保健服务。此外，非政府组织和政府应鼓励健康素养，即组织旨在向农民宣传 NCDs 及其对农业影响的计划。
