ABSTRACT
Objective@#To investigate the prevalence of dyslipidemia among adult professional athletes in Guangdong Province, so as to provide insights into dyslipidemia screening and health management among professional athletes.@*Methods@#In 2019, active athletes at ages of 18 to 30 years were recruited from 12 provincial sports teams in Guangdong Province using a cluster sampling method. A self-designed questionnaire survey was conducted to collect gender, age and sport items, and the levels of triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were detected. The non-HDL-C level was calculated, and the gender- and sport item-specific prevalence of dyslipidemia was estimated.@*Results@#Totally 460 athletes were investigated, including 245 males (53.26%) and 215 females (46.74%), with a mean age of (21.91±2.77) years. The overall detection of dyslipidemia was 25.87%, and the detection rates of high TG, high TC, high LDL-C, low-HDL-C and high non-HDL-C were 20.22%, 5.87%, 13.04%, 3.26% and 9.57%, respectively. The detection rates of high TG (9.39% vs. 1.86%; χ2=11.743, P<0.05), low HDL-C (5.31% vs. 0.93%; χ2=6.951, P<0.05) and high non-HDL-C (12.24% vs. 6.51%; χ2=4.351, P<0.05) were significantly greater in men than in women, and the detection of high TC was lower in men than in women (17.96% vs. 22.79%; χ2=8.627, P<0.05). There was a significant difference in the detection of dyslipidemia among athletes engaging in different sport items (χ2=47.552, P<0.05), and a high detection rate of dyslipidemia was seen in baseball athletes (34.29%), softball athletes (37.04%), shooting/archery athletes (52.73%).@*Conclusion@#The prevalence of dyslipidemia was 25.87% among adult professional athletes in Guangdong Province, and high TC in combination with high LDL-C were the predominant type of dyslipidemia. The management of blood lipids should be given a high priority to male athletes and baseball, softball and shooting/archery athletes.
ABSTRACT
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 serum ferritin 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 female small ball athletes,including 20 handball,20 hockey and 14 softball players,were selected to complete a self-designed diet questionnaire based on KAP education mode and their serum ferritin indicators 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 average KAP score was 185.10 ± 23.01,with a passing rate of 44.4％.(2)The one-way ANOVA found that there were significant differences in the average A score and the total KAP score (P＜0.05) among the athletes of different small ball teams.The correlation analysis results showed that the average A score was of significant positive correlation to the average P score.Moreover,the average KAP total score was of significant correlation with sports events (P＜0.05) and the education level (P＜0.05),but not with the age,training period and exercise level(P＞0.05).The multiple stepwise regression analysis results showed that training period(P＜0.05) and sports events(P＜0.05) was the influencing factor of nutrition knowledge and attitude respectively,and that education level (P＜0.01) was the influencing factor of both nutrition practice and KAP.(3)Significant differences were found in the serum ferritin among athletes of different sports events(P＜0.05)the serum ferritin was of significant positive correlation with the nutrition knowledge(P＜0.05).Conclusion (1)The lack of sports nutrition knowledge and the unbalance of nutrition behavior are common in elite female small ball athletes,but they had a positive attitude.It is necessary to carry out a series of effective nutrition education programs to improve their sports nutrition 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) The sport event is the key influencing factor of the nutrition attitude and dietary behaviors,which suggests that more more attention should be paid to athletes' dietary management and focus should be put on their diary behavior on no-training days and on their energy ratios control of each meal,especially breakfast 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.
