♂, man; ♀, woman; N, number; pNN50, percentage of successive normal sinus RR intervals >50 ms; LF, low frequency; HF, high frequency; LF/HF, low frequency/high frequency; b, regression coefficient of the time^*predictor parameter to show the longitudinal relation—p, significance; Model 1, correction for age, socioeconomic status; Model 2, Model 1 + body fat%; Model 3, Model 2 + mean heart rate. Bold indicates p < 0.05.
