Water-related health challenges on First Nations reserves in Canada have been previously documented. Our objective was to describe factors associated with self-reported health effects from tap water in 8 First Nations reserve communities in Saskatchewan, Canada. Community-based participatory approaches were used in designing and implementing cross-sectional household surveys. Individual, household, community, and contextual effects were considered in multilevel analysis. Negative health effects from tap water were reported by 28% of households (n = 579). Concerns about environmental factors affecting water quality (odds ratio [OR] = 3.4, 95% confidence interval [CI] = 1.8-6.7), rarely or never drinking tap water (OR = 2.9, 95% CI = 1.3-6.6), insufficient tap water (OR = 3.0, 95% CI = 1.4-6.3), paying for bottled water (OR = 3.2, 95% CI = 1.2-8.7), and dissatisfaction with tap water were associated with self-reported health effects (n = 393); however, the effect of dissatisfaction was modified by respondent age ( = .03). Quality and availability were associated with perceptions of health effects from drinking water, providing additional information on how ongoing concerns about drinking water influence self-reported health in some First Nations.
加拿大原住民保留地与水相关的健康挑战此前已有记录。我们的目标是描述加拿大萨斯喀彻温省8个原住民保留地社区中与自来水自我报告的健康影响相关的因素。在设计和实施横断面家庭调查时采用了基于社区的参与式方法。在多层次分析中考虑了个体、家庭、社区和背景影响。28%的家庭（n = 579）报告了自来水对健康的负面影响。对影响水质的环境因素的担忧（比值比[OR]=3.4，95%置信区间[CI]=1.8 - 6.7）、很少或从不饮用自来水（OR = 2.9，95% CI = 1.3 - 6.6）、自来水供应不足（OR = 3.0，95% CI = 1.4 - 6.3）、购买瓶装水（OR = 3.2，95% CI = 1.2 - 8.7）以及对自来水的不满与自我报告的健康影响相关（n = 393）；然而，不满的影响因受访者年龄而有所改变（P = 0.03）。水质和可获得性与饮用水对健康影响的认知相关，这为一些原住民持续关注饮用水如何影响自我报告的健康提供了更多信息。
