Ambulatory blood pressure (ABP) measurements were performed in a Danish population of 295 males and 275 females aged 19-21 years. Individualised day and night periods were defined from the subjects own recording of bedtime and rising on the day of their ABP measurements. During these individualised periods the ABP values for daytime, night-time and for the whole 24-h period were measured. The mean +/- s.d. values for systolic/diastolic ABP for the whole population were (124+/-11)/(70+/-7) mm Hg in the daytime, (106+/-12)/(60+/-9) mm Hg in the night-time, and (120+/-11)/(68+/-7) mm Hg in the whole 24-h period. Males had a mean systolic ABP of 9 mm Hg and mean diastolic ABP of 5 mm Hg higher than females. In males mean +/- s.d. systolic/diastolic ABP values in the daytime were (129+/-10)/(73+/-7) mm Hg, in the night-time (111+/-12)/(63+/-8) mm Hg, and in the whole 24-h period (125+/-10)/(71+/-7) mm Hg. The corresponding values in females were (119+/-10)/(68+/-6) mm Hg, (103+/-11)/(57+/-8) mmHg, and (115+/-10)/(66+/-6) mm Hg, respectively. In conclusion this study provides sex-specific normal values for ABP in a 19 to 21-year-old age group based on individualised daytime and night-time periods.
对丹麦295名年龄在19至21岁之间的男性和275名同龄女性进行了动态血压（ABP）测量。根据受试者在ABP测量当天自行记录的就寝时间和起床时间来确定个性化的白天和夜间时段。在这些个性化时段内，测量白天、夜间以及整个24小时期间的ABP值。整个人群收缩压/舒张压ABP的均值±标准差在白天为（124±11）/（70±7）毫米汞柱，夜间为（106±12）/（60±9）毫米汞柱，24小时期间为（120±11）/（68±7）毫米汞柱。男性的平均收缩压ABP比女性高9毫米汞柱，平均舒张压ABP比女性高5毫米汞柱。男性白天收缩压/舒张压ABP的均值±标准差为（129±10）/（73±7）毫米汞柱，夜间为（111±12）/（63±8）毫米汞柱，24小时期间为（125±10）/（71±7）毫米汞柱。女性相应的值分别为（119±10）/（68±6）毫米汞柱、（103±11）/（57±8）毫米汞柱和（115±10）/（66±6）毫米汞柱。总之，本研究基于个性化的白天和夜间时段，提供了19至21岁年龄组ABP的性别特异性正常值。
