Objective To investigate the status quo of nutrition knowledge,attitude and practice(KAP)among elite female small ball athletes of Guangdong province and its influencing factors. Their serumferritin was also observed to explore its correlation with their KAP,so as to provide evidences for formulating and implementing scientific and reasonable nutrition education schemes. Methods Fifty-four fe-male small ball athletes,including 20 handball,20 hockey and 14 softball players,were selected to com-plete a self-designed diet questionnaire based on KAP education mode and their serum ferritin indica-tors were analyzed at the same time. Results(1)The average scores(all out of 100)of nutrition knowledge(K),attitude(A)and practice(P)were 43.64 ± 11.66(with a failure rate of 90.7%),78.37 ± 10.21(with the rate of excellence of 59.3%)and 63.10 ± 10.17(with a passing rate of 37.0%),and the aver-age KAP score was 185.10 ± 23.01,with a passing rate of 44.4%.(2)The one-way ANOVA found thatthere were significant differences in the average A score and the total KAP score(P0.05)among theathletes of different small ball teams. The correlation analysis results showed that the average A scorewas of significant positive correlation to the average P score. Moreover,the average KAP total scorewas of significant correlation with sports events(P0.05)and the education level(P0.05),but not withthe age,training period and exercise level(P0.05). The multiple stepwise regression analysis resultsshowed that training period(P0.05) and sports events(P0.05) was the influencing factor of nutritionknowledge and attitude respectively,and that education level(P0.01) was the influencing factor ofboth nutrition practice and KAP.(3)Significant differences were found in the serum ferritin among ath-letes of different sports events(P0.05)the serum ferritin was of significant positive correlation with thenutrition knowledge(P0.05). Conclusion(1)The lack of sports nutrition knowledge and the unbalanceof nutrition behavior are common in elite female small ball athletes,but they had a positive attitude. Itis necessary to carry out a series of effective nutrition education programs to improve their sports nutri-tion knowledge,cultivate their good nutrition attitudes and finally formulate rational and effective nutritional intervention measures to promote the formation of healthy nutrition behavior of athletes.(2)Thesport event is the key influencing factor of the nutrition attitude and dietary behaviors,which suggeststhat more more attention should be paid to athletes' dietary management and focus should be put ontheir diary behavior on notraining days and on their energy ratios control of each meal,especiallybreakfast and extra meals,and rational intake of snacks.(3)The incidence of iron deficiency is consistent with KAP questionnaire survey results,which indicates that it may be an effective measure to prevent iron deficiency anemia through strengthening athletes' dietary nutrition education.
