Influence of Sex, Blood Group, Secretor Character, Smoking Habits, Acetylsalicylic Acid, Oral Contraceptives, Fasting and General Health State on Blood Coagulation Variables in Randomly Selected Young Adults
Blood samples were drawn from 129 randomly selected young adults. Intake of acetylsalicylic acid (ASA), contraceptive drugs, smoking habits and health state were registered. Males had significantly higher systolic blood pressure, shorter bleeding time and lower VIII:C. Smoking was only correlated to some variables assessed in the female group. Users of oral contraceptives smoked more, had a shorter bleeding time and higher fibrinogen levels. Factor VIIIR;Ag was elevated only in female smokers with blood group non-O. Non-secretors had shorter bleeding times and a tendency towards higher VIIIR:Ag.
