Int. J. Environ. Res. Public Health 2011, 8 572 scores (8–10), and the lower extreme scores (1–3) are only 6% of the total responses. This represents a balanced, somewhat more pro-environmental view towards the relationship between protection of nature and human use of natural resources. Mean age of the survey respondents was 56.8, while average formal educational achievement was between “some college” and “college degree.” About two thirds of the respondents were male. 3.2. Logistic Regression Model 1: Primary Bottled Water Users Our first model used a logistic regression model to examine the relationship between primary bottled water users and water quality perceptions (Table 2). Table 2. Logistic Regression for primary bottled water users (N = 3,232). OR Variables CI 95% (Odds Ratio) Surface water quality 0.778 * 0.593–1.021 Ground water quality 0.670 *** 0.529–0.849 Environmental attitudes 0.967 0.897–1.041 Age 0.978 *** 0.970–0.986 Community size 1.116 ** 1.014–1.229 Education 0.915 0.817–1.025 Gender (control: male) 1.323 ** 1.025–1.707 Drinking water (control: safe) 5.884 *** 4.464–7.757 Region (control: region 9) Region 4 0.764 0.550–1.061 Region 6 0.966 0.692–1.348 Region 7 0.191 *** 0.108–0.337 Region 8 0.470 *** 0.317–0.697 Pseudo R2 (Nagelkerke) 0.263 Note: * P < 0.10; ** P< 0.05; *** < 0.001. We found that groundwater quality perception was a significant predictor. As the ground water quality perception increased by one ascending-ordered category, the odds of a person using bottled water as primary source of drinking water was reduced by 33%. Compared with a person who feels their home water is safe to drink, a person who does not trust their home drinking water safety was more than 4.8 times more likely to use bottled water as their primary source of drinking water. However, there was no significant difference in bottled water use among respondents with different surface water quality perceptions. Environmental attitudes were not a significant predictor for primary bottled water use. Age and gender were also found to be significant predictors for bottled water use. When all other conditions were exactly equal, a respondent who was one year older in age was about 2% less likely to use bottled water as the primary source of drinking water. From a gender standpoint, the odds that a female uses bottled water for primary drinking source are 1.32 times as much as the odds for a male, with all other conditions being equal. Education level was not a significant predictor for bottled water use.
