Sample sizes (N), means, SDs, 95% CIs (minimum and maximum provided for Adult Age) for adulthood cardiac structure, body size and composition, and lifestyle measurements. Cardiac Structure includes LVMI, RWT, and IVST (both systolic and diastolic). Body size, composition and blood pressure measurements include BMI, WCHt, %BF, FFM, TBF, SBP and DBP. Lifestyle measurements include ALC, SMK and PA.

SD: standard deviation.

Min, Max: Minimum and Maximum.

CI: Confidence Interval.

LVMI: Left-ventricular mass index, g/m^2.7.

RWT: Relative wall thickness, cm.

IVSTs: interventricular septum thickness – systolic, cm.

IVSTd: interventricular septum thickness – diastolic, cm.

BMI: Body mass index, kg/m².

WCHt: Waist circumference divided by height, %.

%BF: Percentage body fat, %.

FFM: Fat-free mass, kg.

TBF: Total body fat, kg.

ALC: Number of servings of alcohol consumed per day.

SMK: Number of cigarettes smoked per day.

PA: Physical activity index (scale 1–5).
