Table 1 Basic characteristics of biomarkers and lifestyle factors, divided by sex, for the 834 study participants in the LBA study. P-value and significance indicate differences between women and men

From: The importance of cardiorespiratory fitness and sleep duration in early CVD prevention: BMI, resting heart rate and questions about sleep patterns are suggested in risk assessment of young adults, 18–25 years

BMI body mass index, Body fat (%) percentage of body fat, HDL-C high-density lipoprotein cholesterol, LDL-C low-density lipoprotein cholesterol, Resting HR resting heart rate, MAP mean arterial pressure, HOMA-IR homeostasis model assessment of insulin resistance, MVPA moderate- and vigorous intensity physical activity and CRF cardiorespiratory fitness measured as estimated maximal oxygen uptake, VO2 max
  2. Data are presented as mean and SD. Differences between women and men were analysed by unpaired Student’s t-test. Food habits and MVPA are presented as median and interquartile range (Q1-Q3). Differences in food habits and MVPA between women and men were analysed by Mann-Whitney U test
  3. Levels of significance were set to P < 0.05 = *, P < 0.01 = ** or P < 0.001 = *** and NS, not significant
