[HDL and LDL cholesterol changes in psychological stress in relation to stress experience]

During examinations and after a three-month examination period the changes of the parameters of fat metabolism were investigated depending upon stress experience before examinations. Students with a distinct stress experience showed a higher total cholesterol and LDL-cholesterol as well as a higher LDL/HDL-cholesterol quotient within a concrete examination. After the examination period in this group a higher LDL/HDL-cholesterol quotient and a lower HDL-cholesterol level was established in comparison to the group with an insignificant stress experience. A positive dependence on the initial value of the parameters of fat metabolism consists only in the group with distinct stress experience. According to these results also stress has an influence on the reactions of the fractions of cholesterol.
