HDL‐C, HDL cholesterol; non‐HDL‐C, non‐HDL cholesterol.

Day (9:00 h – 23:00 h and 8.00 h – 9.00 h) and night (23:00 h – 8:00 h) mean values were calculated using the individual 24‐h serum cholesterol concentrations. Day–Night difference was calculated by subtracting the individual mean night value from mean day value. Data are presented as means ± SEM.

^a P‐value calculated between day and night based on paired Student's t‐test.

^b P‐value calculated of day–night difference between offspring and controls, Student's t‐test.
