*The analytic sample only included participants who remained in the four baseline CARDIA cities at any given examination year, with a total of 4314, 2461, 1727, 1480, 1202 and 1119 participants at baseline and examination years 7, 10, 15, 20 and 25, respectively.
†One-way ANOVA was used to test whether the difference between values at baseline and examination year 25 was statistically significantly different from one another.
