Table_1_HIARA study protocol: impacts of artificial coral reef development on fisheries, human livelihoods and health in southwestern Madagascar.DOCX

The Health Impacts of Artificial Reef Advancement (HIARA; in the Malagasy language, “together”) study cohort was set up in December 2022 to assess the economic and nutritional importance of seafood for the coastal Malagasy population living along the Bay of Ranobe in southwestern Madagascar. Over the course of the research, which will continue until at least 2026, the primary question we seek to answer is whether the creation of artificial coral reefs can rehabilitate fish biomass, increase fish catch, and positively influence fisher livelihoods, community nutrition, and mental health. Through prospective, longitudinal monitoring of the ecological and social systems of Bay of Ranobe, we aim to understand the influence of seasonal and long-term shifts in marine ecological resources and their benefits to human livelihoods and health. Fourteen communities (12 coastal and two inland) were enrolled into the study including 450 households across both the coastal (n = 360 households) and inland (n = 90 households) ecosystems. In the ecological component, we quantify the extent and health of coral reef ecosystems and collect data on the diversity and abundance of fisheries resources. In the social component, we collect data on the diets, resource acquisition strategies, fisheries and agricultural practices, and other social, demographic and economic indicators, repeated every 3 months. At these visits, clinical measures are collected including anthropometric measures, blood pressure, and mental health diagnostic screening. By analyzing changes in fish catch and consumption arising from varying distances to artificial reef construction and associated impacts on fish biomass, our cohort study could provide valuable insights into the public health impacts of artificial coral reef construction on local populations. Specifically, we aim to assess the impact of changes in fish catch (caused by artificial reefs) on various health outcomes, such as stunting, underweight, wasting, nutrient intake, hypertension, anxiety, and depression.

人工礁开发健康影响（Health Impacts of Artificial Reef Advancement，缩写HIARA；在马达加斯加语中意为"携手"）研究队列于2022年12月组建，旨在评估海鲜对于马达加斯加西南部拉诺贝湾沿岸沿海居民的经济与营养重要性。
本研究将持续至至少2026年，我们旨在解答的核心问题为：人工珊瑚礁的建设能否恢复鱼类生物量、提升渔获量，并对渔民生计、社区营养与心理健康产生积极影响。
通过对拉诺贝湾的生态与社会系统开展前瞻性纵向监测，本研究旨在阐明海洋生态资源的季节与长期变化规律，及其对人类生计与健康的影响。
本研究共纳入14个社区（12个沿海社区、2个内陆社区），覆盖沿海生态系统（n=360户）与内陆生态系统（n=90户）的450户家庭。
在生态研究模块中，我们将量化珊瑚礁生态系统的规模与健康状况，并收集渔业资源的多样性与丰度数据。
在社会研究模块中，我们将收集饮食结构、资源获取策略、渔业与农业生产方式，以及其他社会、人口与经济指标数据，每3个月开展一次重复调研。
每次调研访视均采集临床检测数据，包括人体测量指标、血压检测结果及心理健康诊断筛查结果。
通过分析距人工礁建设点不同距离区域的渔获量与消费模式变化，及其对鱼类生物量的相关影响，本队列研究可为人工珊瑚礁建设对当地人群的公共健康影响提供极具价值的研究见解。
具体而言，本研究旨在评估人工礁引发的渔获量变化对多种健康结局的影响，包括发育迟缓、体重不足、消瘦、营养摄入、高血压、焦虑与抑郁。
