Drinking water consumption patterns in British Columbia: an investigation of associations with demographic factors and acute gastrointestinal illness.
A cross-sectional telephone survey was performed in the province of British Columbia, Canada, to investigate drinking water consumption patterns and their associations with various demographic characteristics and acute gastrointestinal illness (AGI). Water consumption included plain water and water used in the preparation of cold beverages. The median amount of water consumed daily was four-250 mL servings (1.0 L), although responses were highly variable (0 to 9.0 L). Alternative water use was common: bottled water was the primary source of drinking water (i.e. >or=75% of the total daily water intake) for 23% of respondents and 47% of households used in-home water treatment methods. Approximately 10% of respondents reported an episode of AGI (vomiting or diarrhea) in the previous 4-week period. Such illness was associated with age (continuous variable in years, OR=-0.98), sex (male vs. female, OR=0.8) and the amount of water consumed (continuous variable in 250-mL servings, OR=1.06); however, a causal relationship with water consumption cannot be established based on this study alone. Overall, the associations of drinking water patterns with age, sex, education, and household income serve as important reminders to researchers and public health professionals of the non-uniform nature of drinking water consumption, and indicate potential differences in exposure to waterborne hazards in this population.
