摘要: 目的 探讨性别、年龄和ABO血型与血小板计数的关系。方法 4 657名健康献血者被纳入研究。血型采用血清学方法确定,血小板计数由自动血液分析仪测定。使用R软件(4.4.1)分析各项关联。结果 男性平均血小板计数低于女性[男性:(243±45.3)×109/L,女性:(259±50.2)×109/L](t=-10.15,P<0.001)。年龄与血小板计数在两性中均呈负相关(男性:r=-0.13,女性:r=-0.14;均P<0.001)。按年龄分层的趋势分析显示,总体随年龄下降;男性呈持续缓慢下降,而女性在30~49岁相对稳定。多元线性回归分析表明,性别、年龄和ABO血型为血小板计数的独立影响因子;B型献血者的血小板计数低于A型(P<0.05)。结论 男性血小板计数低于女性。血小板计数随年龄缓慢下降,女性存在相对稳定的阶段。不同血型与血小板计数相关,提示其可能是影响血小板计数的一个遗传性状。

Abstract: Objective This study is to assess associations of sex, age, and ABO blood group with platelet counts. Methods A total of 4 657 healthy donors were enrolled. ABO groups were determined serologically and platelet counts measured by automated hematology analyzer. Associations were evaluated using R software (4.4.1). Results Mean platelet count was lower in males [(243±45.3)×109/L] than that in females [(259±50.2)×109/L] (t=-10.15, P<0.001). Age correlated negatively with platelet count in both sexes (male: r=-0.13, female: r=-0.14; both P<0.001). Age-stratified trend analysis showed an overall decline with age; males exhibited a steady gradual decrease, while females remained relatively stable between ages 30~49. Multivariable linear regression identified sex, age, and ABO group as independent predictors; group B had lower platelet counts than group A (P<0.05). Conclusion Platelet counts are lower in males than in females. Platelet counts decline slowly with age, with a relatively stable phase in females. ABO blood group is associated with platelet count; it may be a heritable trait affecting platelet count.

Key words: Sex, Age, ABO blood group, Platelet count
