Values are means (SD); n, number of participants. *Avon Longitudinal Study of Parents and Children (ALSPAC) population-specific indexed height 0.82 for left ventricular mass (LVM) indexed (LVMI) measures at 17 yr and 0.58 for LVMI measures at 24 yr. Differences between sexes were tested using Student’s t test. P < 0.05, statistically significant for sex differences.
