Fish consumption comprises an important part of what the Anishinaabe (Great Lakes Native Americans) call "minobimaadiziiwin" which translates roughly to "living in a good way". Industrial activity leading to the accumulation of persistent contaminants in fish disrupts minobimaadiziiwin. Our team of academic and Anishinaabe scientists co-developed a fish consumption advisory for the Anishinaabe using software that can be accessed via mobile phones and/or the internet.
The software, Gigiigoo'inaan ("our fish") is designed to improve environmental health literacy using culturally congruent messaging and aesthetics. We tested the following hypotheses: 1) the Gigiigoo'inaan would encourage consumption of fish high in Polyunsaturated Omega-3 fatty acids (PFUA-3) whilst minimizing contaminant intake (methylmercury (MeHg) and Polychorinated Biphenyls (PCBs)); and 2) intervention participants will be more likely than controls to achieve a favorable n-3 PUFA/MeHg consumption ratios.
We conducted a randomized controlled trial with prospective self-reported fish consumption using automated email surveys. One-month pre and one month post, control and intervention outcome variables were calculated per participant as µg/kg/day of MeHg, µg/kg/day of PCB, g of fish, and mg/day of EPA+DHA. These were modeled using an analysis of covariance (ANCOVA) with a-priori covariates: age, sex, and tribal affiliation.
Most participants in both trial arms reported eating relatively elevated amounts of fish yet remained within advisory guidelines for contaminants. EPA+DHA:MeHg ratios were also favorable in most participants. Advisory limits for contaminants were exceeded by relatively few participants in the study.
Gigiigoo'inaan was previously reported to increase confidence, the current user feedback confirms this. Most participants ate fish but did not exceed the advisory limits, which demonstrates Environmental Health Literacy progress in the region despite a lack of observed behavior change during the trial. A small number of participants exceeded contaminant intake guidelines which matches the pilot work for this study.
鱼类消费是阿尼希纳比贝（大湖地区的北美原住民）所谓的“minobimaadiziiwin”的重要组成部分，大致翻译为“以好的方式生活”。导致鱼类中持久性污染物积累的工业活动扰乱了 minobimaadiziiwin。我们的学术和阿尼希纳比贝科学家团队合作开发了一种针对阿尼希纳贝的鱼类消费咨询，使用可以通过手机和/或互联网访问的软件。
该软件 Gigiigoo'inaan（“我们的鱼”）旨在通过使用文化上一致的信息和美学来提高环境健康素养。我们检验了以下假设：1）Gigiigoo'inaan 将鼓励食用富含多不饱和ω-3 脂肪酸 (PFUA-3) 的鱼类，同时最大限度地减少污染物摄入（甲基汞 (MeHg) 和多氯联苯 (PCBs)）；2）干预参与者比对照组更有可能实现有利的 n-3 PUFA/MeHg 消费比例。
我们使用自动电子邮件调查进行了一项随机对照试验，前瞻性自我报告鱼类消费。每个参与者的一个月前和一个月后的控制和干预结果变量分别计算为µg/kg/天的 MeHg、µg/kg/天的 PCB、g 的鱼和 mg/天的 EPA+DHA。这些使用协方差分析 (ANCOVA) 进行建模，具有预先设定的协变量：年龄、性别和部落归属。
试验组和对照组的大多数参与者都报告说食用了相对较高量的鱼类，但仍符合污染物咨询建议。大多数参与者的 EPA+DHA：MeHg 比例也很有利。研究中相对较少的参与者超过了污染物的咨询限制。
Gigiigoo'inaan 之前被报道可以提高信心，当前的用户反馈证实了这一点。大多数参与者吃鱼，但没有超过咨询限制，这表明尽管在试验期间没有观察到行为变化，但该地区的环境健康素养取得了进展。少数参与者超过了污染物摄入指南，这与该研究的试点工作相符。
