Abbreviations: BNH = Black, non-Hispanic, MA = Mexican American, WNH = White, non-Hispanic; BMI = body mass index.
*Laboratory sample weights were used in all analyses. Actual sample numbers are presented with their weighted results expressed as standard error range in the 95% confidence intervals.
† MA and BNH were compared to WNH for all analyses. Variables with p-values for each group (MA and BNH) that are < 0.05 are significantly different than WNH.
