Abstract

Objective To explore population characteristics of voluntary blood donors of central urban and suburban blood donation houses in Chengdu City from 2012 to 2016, in order to provide support and reference for optimizing promotion of blood donation house and recruitment strategy of voluntary blood donors. Methods From 2012 to 2016, a total of 73 305 voluntary blood donors who participated in blood donation at 16 blood donation houses in Chengdu were selected as subjects in this study. According to the different regions of voluntary blood donors participating in blood donation, they were divided into the suburban blood donation houses group (n=17 028) and central urban donation houses group (n=56 277). The demographic data such as age, education levels and occupation of voluntary blood donors in this study were collected by Chengdu Blood Center Information Management System SHINOW9.0. A retrospective analysis was conducted to compare the distribution of voluntary blood donors′ age, education levels and occupation between suburban and central urban blood donation houses group. The composition ratios of the two groups of voluntary blood donors with different age, educational levels and occupation were compared by chi-square test, respectively. Results ① There was statistically difference in composition ratios of different ages of voluntary blood donors between suburban and central urban blood donation houses group in Chengdu from 2012 to 2016 (χ2 =3 204.590, P<0.001). The voluntary blood donors in suburban blood donation houses group were mainly concentrated in the age of 25-54 years old, with the proportion of 83.0% (14 131/17 028), and the proportion of 35-44 years old voluntary blood donors was the highest, account for 35.6% (6 061/17 028). The voluntary blood donors in central urban blood donation houses group were mainly concentrated in the age of 18-44 years old, with the proportion of 87.0% (48 949/56 277), among which proportion of 18-24 years old voluntary blood donors was the highest, account for 32.1% (18 091/56 277). ② There was statistically difference in composition ratios of different education levels between suburban and central urban blood donation houses groups in Chengdu from 2012 to 2016 (χ2=32 987.363, P<0.001). The education levels of voluntary blood donors in suburban blood donation houses group were mainly of junior high school, high school and specialty education, with proportion of 82.2% (14 005/17 028), among them the proportion of voluntary blood donors with junior high school education was the highest, account for 34.7% (5 912/17 028). The education levels of voluntary blood donors in central urban blood donation houses group were mainly of high school, specialist and undergraduate education, with proportion of 71.9% (40 454/56 277), and proportion of specialist education voluntary blood donors was the highest, account for 29.6% (16 669/56 277). ③ There was statistically difference in composition ratios of occupation between central suburban and urban blood donation houses groups in Chengdu from 2012 to 2016 (χ2 =4 127.468, P<0.001). The main occupations of voluntary blood donors in suburban blood donation houses group were farmers, account for 17.9% (3 053/17 028); public officials, account for 12.2% (2 084/17 028) and workers, account for 12.2% (2 083/17 028).

Conclusions The population characteristics of voluntary blood donors in suburban and central urban blood donation houses are different in Chengdu City.
