Poor tap water quality experiences and poor sleep quality during the Flint, Michigan Municipal Water Crisis

Objectives: After inadequate official response to community concerns over water quality following changes in Flint's municipal water supply, this study sought evidence for a relationship between water quality and community mental health. Design: The Speak to Your Health Community Survey is a community-based participatory component of the health surveillance system in Genesee County, Michigan. This cross-sectional survey recruits participants from every residential Census Tract of the county and strives for demographic representativeness. Results: Respondents (n = 834) rated their tap water quality (taste, smell, appearance) as poor (36%), fair (18%), good (20%), very good (17%), and excellent (10%). They rated their sleep quality as poor (12%), fair (28%), good (39%), very good (18%), and excellent (4%), and had an average (SD) sleep length of 408 (90) minutes. Controlling for age, sex, years of education, and whether respondents were African American and Hispanic/Latino/a, lower perceived tap water quality was associated with lower sleep quality and shorter sleep length. Conclusion: Results indicate that adverse health conditions related to the water crisis extend beyond lead poisoning in children and include deterioration of sleep conditions among adult residents.
