*Analysis of covariance (p value adjusted for age).
NS indicates p > 0.05; ^f, females only; ^w, whites only.
^† Mean values are presented and their Log transformed values were used to calculate p values.
^‡ p < 0.05 baseline survey vs follow-up survey.
^§ p < 0.01 baseline survey vs follow-up survey.
^¶ p < 0.001 baseline survey vs follow-up survey.
