This study investigated the characteristics of the personal background variables of anemia vocational high school students, and statistically analyzed the status and differences in anemic prevention nutritional knowledge and dietary behaviors of anemia and non-anemia vocational high school students. We further analyzed the correlation between nutritional knowledge and dietary behaviors. Because anemia may cause insufficient oxygen supply in the brain and affect learning, this study also compares the differences in academic performance. We selected 50 students with anemia (anemia group) and 50 normal students (non-anemia group) for this study according to the results of freshmen health inspection. We also tested the differences of academic performance between anemia group and non-anemia group students. The correlation between anemia-prevention nutrition knowledge and dietary behaviors were also examined. A self-administered questionnaire which included individual background factors, anemia-prevention nutrition knowledge and dietary behaviors were used to collect data. Data were analyzed using descriptive and inferential statistics. The findings were as follows: (1) With regarding to individual background variables, there were higher percentages of anemia students in 'female', 'overweight or underweight', 'daily pocket money less than 150 New Taiwan dollars', 'mother's academic level is (vocational) high school', 'mother's academic level is university/college' anemia subgroups. Furthermore, the proportion of anemia was high in the subgroup with longer than 7 days menstrual cramps duration. There were about one third of anemia-group students with negative awareness of anemia. (2) The average scores of anemia-prevention nutrition knowledge for anemia group and non-anemia group were 4.18±1.49 and 4.54± 1.38 (total score 10), respectively. There was no significant difference between anemia and non-anemia group. (3) The average scores of anemia-prevention dietary behaviors for anemia group and non-anemia group were 28.1±9.7 and 29.3±9.6 (total score 50), respectively. There was no significant difference between anemia and non-anemia group. (4) There was no significant correlation between anemia-prevention nutrition knowledge and dietary behaviors. (5) The average scores of common and professional courses, including English, Mandarin, mathematics, facial beauty, skin care courses for anemia group students were significantly lower than non-anemia group. However, there was no difference between anemia and non-anemia groups in average score of gym lessons. This study suggests that freshmen health inspection results should inform students and their parents. Teachers must make sure that students with anemia receive follow-up medical care to improve health of students. Teachers at high schools are advised to incorporate issues such as anemia related nutrition knowledge into their teaching materials to fortify students with good anemia-prevention nutrition knowledge. High schools are also recommended to conduct anemia-prevention diet workshop for students to prepare meal for themselves and to reduce the morbidity of anemia.
