Demographic Data

	Young Group ≤30 years (n=32)	Old Group ≥50 years (n=32)	P Value
Age (yr)	26±2.8	61.8±7.6
BMI (kg/m²)	22.7±3	27.1±6.1	0.001
White (%)	78.1	90.6	0.168

BMI = body mass index.

Data are means±standard deviations unless otherwise indicated (Student's t-test, chi-squared test).

Statistical analysis was not performed for age (study design). Although the chi-squared test showed that there was no significant difference in comparing white and non-white females, the study's sample size did not allow for detailed racial differences to be addressed.
