^*Low relative height defined as more than 2 standard deviations below the standard mean height-for-age or a height z-score of <−2.0. Underweight defined as more than 2 standard deviations below the standard mean BMIfor-age or a BMI z-score of <−2.0. For ages 5–20 y, z-scores were calculated using NCHS/WHO growth standards; for ages 21–3 0 y, z-scores were calculated using mean height and BMI standards for African-American adults from NHANES III were used to calculate z-scores.
