Concerns regarding the safety and aesthetic qualities of one's municipal drinking water supply are important factors influencing drinking water perceptions and consumption patterns (i.e. sources used and daily volume of consumption). In northern Canada, Inuit communities face challenges with drinking water quality, and many Inuit have reported concerns regarding the safety of their drinking water. The objectives of this research were to describe perceptions of municipal tap water, examine use of water sources and changes following the installation of a potable water dispensing unit (PWDU) in 2014, and identify factors associated with water consumption in the Inuit community of Rigolet. This study used data from three cross-sectional census surveys conducted between 2012 and 2014. Principal component analysis (PCA) was used to aggregate data from multiple variables related to perceptions of water, and logistic regressions were used to identify variables associated with water consumption patterns. Three quarters of residents reported using the PWDU after its installation, with concomitant declines reported in consumption of bottled, tap, and brook water. Negative perceptions of tap water were associated with lower odds of consuming tap water (OR=0.73, 95% CI 0.56-0.94; OR=0.67, 95% CI 0.49-0.93); women had higher odds of drinking purchased water compared to men (OR=1.90, 95% CI 1.11-3.26). The median amount of water consumed per day was 1L. Using brook water (OR=2.60, 95% CI 1.22-5.56) and living in a household where no one had full-time employment (OR=2.94, 95% CI 1.35-6.39) were associated with consuming >2L of water per day. Results of this study may inform drinking water interventions, risk assessments, and public health messaging in Rigolet and other Indigenous communities.
人们对市政饮用水的安全性和美学质量的担忧是影响饮用水认知和消费模式的重要因素（即使用的水源和每天的消耗量）。在加拿大北部，因纽特人社区面临着饮用水质量的挑战，许多因纽特人表示担心他们的饮用水安全。本研究的目的是描述对市政自来水的看法，研究在 2014 年安装饮用水分配装置（PWDU）后对水源的使用情况和变化，并确定与里戈莱特因纽特社区的用水有关的因素。本研究使用了 2012 年至 2014 年期间进行的三次横断面普查调查的数据。主成分分析（PCA）用于聚合与水的认知有关的多个变量的数据，并使用逻辑回归确定与用水模式相关的变量。四分之三的居民报告在安装 PWDU 后使用它，同时报告瓶装水、自来水和溪流水的消耗量下降。对自来水的负面看法与自来水消费量较低有关（OR=0.73，95%CI 0.56-0.94；OR=0.67，95%CI 0.49-0.93）；与男性相比，女性饮用购买水的可能性更高（OR=1.90，95%CI 1.11-3.26）。每天饮用的水量中位数为 1 升。使用溪流水（OR=2.60，95%CI 1.22-5.56）和家中无人全职就业（OR=2.94，95%CI 1.35-6.39）与每天饮用超过 2 升水有关。本研究的结果可能为里戈莱特和其他土著社区的饮用水干预、风险评估和公共卫生宣传提供信息。
