目的分析2015年甘肃省朝觐人员血液指标分布情况及影响因素,为制定适合朝觐人群的血液指标参考值范围提供依据。方法对2015年在甘肃国际旅行卫生保健中心体检的3 080名朝觐人员红细胞数(RBC)、血红蛋白数(HGB)、血小板数(PLT)和红细胞平均压积(MCV)4种指标进行检测。结果检测3 080人,RBC和HGB升高比例、PLT和MCV降低比例女性高于男性(P<0.01);RBC和MCV升高与MCV降低人数在各年龄组所占比例差异有统计学意义(P<0.01),其中RBC在41~50岁年龄组升高人数构成比最高为27.72%;临夏州、甘南州、定西市的RBC和HGB升高人数,陇南市、天水市的PLT降低人数和MCV升高人数与其余地区相比差异均有统计学意义(P<0.01);且RBC和HGB与海拔呈正相关(P<0.01),PLT和MCV与海拔呈负相关(P<0.01)。结论在甘肃朝觐人群不同性别、年龄和地区间4种血液指标分布有差异,应根据不同情况制定适宜的参考值范围。
Objective To analyze the distribution and influencing factors of blood indexes of pilgrims in Gansu Province in 2015 and provide evidences for setting reference range of blood indexes suitable for pilgrims. Methods RBC, HGB, PLT and MCV were detected in 3 080 pilgrims who were inspected at the International Travel Health Care Center in 2015 in Gansu Province. Results There were significant differences in the proportion of RBC, MCV and the number of MCV among all age groups (P <0.01) P <0.01). The RBC and RBC increased in Rare-Earth, Gannan and Dingxi counties and the PLT decreased in Longnan and Tianshui cities were the highest There was a significant difference in elevation of MCV between the two groups (P <0.01). RBC and HGB were positively correlated with altitude (P <0.01). PLT and MCV were negatively correlated with altitude (P <0.01). Conclusions There are differences in the distribution of four kinds of blood indicators among different gender, age and region in Hajj in Gansu Province. The appropriate reference value range should be worked out according to different situations.
