  1. SRH self-reported health, PA physical activity, BMI body mass index, RHR resting heart rate, SBP systolic blood pressure, CI 95% confidence intervals, Adj.rate age and gender standarized rates
  2. P-value is based on chi square. SRH: Pearson chi2(6) = 324.5484, p < 0.001; Hard physical activity: Pearson chi2(6) = 6.3e+ 03, p < 0.001; Light physical activity Pearson chi2(6) = 1.2e+ 03, p < 0.001; Daily smokers Pearson chi2(2) = 981.7926, p < 0.001. P-value for the continuous variables are based upon ANOVA grouped on survey time: Comorbidity: F(2) = 385.46, p < 0.001; BMI: F (2) = 699.31, p < 0.001; RHR: F (2) = 1481.70, p < 0.001; SBP: F (2) = 26.44, p < 0.001; Tot.cholesterol F (2) = 612.58, p < 0.001
