ABSTRACT
Objective To investigate the incidence of leukopenia in superficial healthy population and its correlation with age and sex.Methods A total of 40 031 healthy subjects, including 23 393 males and 16 638 females, were selected from January to July, 2018.Their blood routine tests were performed to analyze the age, sex, neutropenia of leukopenia patients.Results The prevalence of leukopenia was 1.22％ (490/40 031), 0.37％ (151/40 031) in males, 0.85％ (339/40 031) in females.The incidence in females was higher, with statistical significance (P＜0.05).Age:the average age of males was higher.There was no difference between the incidence of leukopenia in the population aged less than 60 years and over 60 years.There was no significant difference in lymphocyte and monocyte counts between men and women with leukopenia (P＞0.05), but there was significant difference in WBC and NEU counts (P＜0.05).Neutropenia was found in 206 leukopenia patients, accounting for 42.04％ (206/490), and thrombocytopenia was found in 21 patients, accounting for4.29％ (21/490), and anemia was found in 71 patients, accounting for 14.49％ (71/490).Conclusion The incidence of leukopenia is 1.22％in the apparently healthy population.The incidence of leukopenia in females is higher than that in males.Leukopenia is more severe in women than in men, neutropenia is more severe too.
