*Note.* All estimates are odds radios (ORs) except for bedtime and wake time which are unstandardized Beta estimates; ORs and Beta estimates reflect the change in outcome for each IQR (i.e. 0.52 mg/L) increase in water fluoride concentration. Regression analyses were adjusted for age, sex, race/ethnicity, body mass index, and ratio of family income to poverty. Reweighted MEC weights were applied to these regression analyses; *Significant at *p* ≤ 0.05 after Holm-Bonferroni correction. †The *p*-value for a Type 3 Analysis of Effects with 2 degrees of freedom; ǂ The *p*-value for a Type 3 Analysis of Effects with 4 degrees of freedom; ^{a.} Odds ratio for association between water fluoride and snoring among males; interaction between sex and water fluoride in predicting snoring (B = 1.35, *p* < 0.001)
