Cognition and influencing factors of non-remunerated blood donation among different population in Jiangsu province

Objective To compare and analyze the cognitive level of non-remunerated blood donation among different populations, and to explore the influencing factors of non-remunerated blood donation cognition, and to provide evidence for improving the awareness of non-remunerated blood donation. Methods Using stratified sampling method, the survey area was selected according to geographical location and economic development status. Four cities including Nanjing, Suzhou, Yangzhou and Xuzhou in Jiangsu province were selected, and 2 986 people were effectively investigated by self-designed questionnaires. Results The overall score of cognition of non-remunerated blood donation was more than 60 points in different populations in Jiangsu province, accounting for 44.1%. The cognitive level was most significantly affected by the number of blood donation. The cognition rate of people with blood donation times of 4 times and above was 68.9%, and that of those without blood donation was 24.3%,the difference was statistically significant (P<0.05). The cognition rate of blood donation among urban residents was 50.6%, and that of rural residents was 38.3%, the difference was statistically significant (P<0.05). Conclusions At present, people’s understanding of non-remunerated blood donation is not high, and there are great differences among different groups. Publicity related to non-remunerated blood donation should be strengthened for those with low education level, school students, and rural residents,which may improve the overall cognitive level of non-remunerated blood donation.
