目的定量研究女大学生月经失血量,并对其铁营养状况进行评价。方法用简单随机抽样的方法抽取30名在校女大学生,用调查表收集一般信息。通过称量卫生巾在使用前后的重量,计算收集到卫生巾上的失血量,估计未收集到卫生巾上的失血量,两者相加得月经周期失血量。常规方法测量血中血红蛋白浓度、血清游离原卟啉与血清铁蛋白含量。采用双变量相关分析法分析月经失血量和铁营养状况之间的关系。结果女大学生平均月经周期持续天数为(4.5±1.4)天,平均失血量为(59.3±25.1)g,范围为24～110g。血清铁蛋白、游离原卟啉、血红蛋白的平均含量分别为(25.13±14.33)ng/ml、(0.06±0.01)μg/ml和(131.61±9.76)g/L,22.58%的女大学生处于铁减少期,无临床贫血者。月经失血量与血清铁蛋白含量呈负相关。结论女大学生月经失血量有很大的个体差异,临床上无贫血并不意味着铁营养状况良好,血清铁蛋白是反映机体铁营养状况的敏感指标。
Objective To quantitatively study the female students’ menstrual blood loss and to evaluate their iron nutrition status. Methods A total of 30 female college students were recruited by using simple random sampling method and a general questionnaire was collected. By weighing the weight of the sanitary napkin before and after use, the amount of blood loss collected on the sanitary napkin is calculated, it is estimated that the amount of blood loss on the sanitary napkin is not collected, and the sum of the two amounts is the amount of blood loss in the menstrual cycle. The blood hemoglobin concentration, serum free protoporphyrin and serum ferritin were measured by routine methods. Bivariate correlation analysis was used to analyze the relationship between menstrual blood loss and iron nutrition status. Results The average duration of menstrual cycle in female college students was (4.5 ± 1.4) days, with an average blood loss of (59.3 ± 25.1) g, ranging from 24 to 110 g. The average levels of serum ferritin, protoporphyrin and hemoglobin were (25.13 ± 14.33) ng / ml, (0.06 ± 0.01) μg / ml and (131.61 ± 9.76) g / Period, no clinical anemia. Menstrual blood loss and serum ferritin content was negatively correlated. Conclusions There is a great individual difference in menstrual blood loss among female college students. No clinical anemia does not mean that iron nutrition is good. Serum ferritin is a sensitive index reflecting the nutritional status of iron in the body.
