¹ Results on WC are based on a sub-sample of 250 subjects (176 males and 74 females; low age group [N = 125], high age group [N = 125]; low BMI group [N = 163], high BMI group [N = 87]; low SES group [N = 99], high SES group [N = 151]; smoking [N = 36], non-smoking [N = 212]; medication use [N = 33], no medication use [N = 209]; low frequency of weighing [125], high frequency of weighing [123]).
² 45 subjects (5.2%) had a healthy weight based on their self-reported BMI
