The nutritional health knowledge was investigated using the Chinese Nutrition Health Knowledge Questionnaire for Adults compiled by Chinese Center for Disease Control and Prevention, and the awareness and source of nutritional health knowledge was descriptively analyzed. Results Totally 526 questionnaires were allocated, and 502 valid questionnaires were recovered, with an effective recovery rate of 95.44%. The respondents included 240 men (47.81%) and 262 women (52.19%), and included 343 individuals at ages of 18 to 44 years (68.33%), and 159 individuals at ages of 45 years and older (31.67%). The overall awareness of nutritional health knowledge was 14.54% among regular unpaid blood donors in Zhoushan City, and a higher awareness was seen among female regular unpaid blood donors (17.56%) than among males (11.25%) (P<0.05), while the awareness of nutritional health knowledge was significantly higher among respondents at ages of 18 to 44 years than among those at ages of 45 years and older (16.91% vs. 9.43%, P<0.05). The awareness of nutritional health knowledge was significantly higher among respondents with an educational level of junior college and above than among those with an educational level of high school/technical secondary school/technical school (17.24% vs. 12.22%, P<0.05), and the awareness was significantly higher among respondents with healthcare-related occupations than among those with other occupations (16.44% vs. 14.22%, P<0.05). Wechat, Weibo, Tik Tok and Kuaishou were main routes to obtain nutritional health knowledge (83.86%). Conclusions The awareness of nutritional health knowledge is low among regular unpaid blood donors in Zhoushan City.
