Abstract
Purpose: The purpose of this study was to examine caffeine consumption and the factors that affect caffeine use in high school athletes.
Methods: Three hundred and ninety-four Rhode Island high school athletes (age: 16.8 ± 1.27 years) completed a cross-sectional online survey to assess caffeine consumption. A multivariate logistic regression analysis and binary logistic regression were performed to characterize associations between use and nonuse and the independent variables of ethnicity, grade, sex, and sport played. 95% confidence intervals (CI) were calculated for all models. Statistical significance was set to p ≤ 0.05 for all analysis.
Results: Fifteen point five percent of the variance in caffeine use was related to ethnicity, grade, and sex(R2 = 0.155), with significant results for each variable. A majority of female athletes consumed caffeine (67.4%), compared to male athletes (37.8%) (p < 0.001). Athletes identifying as Caucasian reported significantly more caffeine use (55.9%), compared to athletes from underrepresented backgrounds (32.6%) (p < 0.001). Caffeine use was significantly different across grades, where 30.6% of 9th graders, 49.2% of 10th graders, 55.2% of 11th graders, and 49.2% of 12th graders reported caffeine use (p = 0.049). Coffee (51%) and energy drinks (43%) were the primary sources of caffeine consumption. Dance, cheerleading, and gymnastics participants were more than ten times as likely to consume caffeine compared to other sports (95% CI [2.28, 48.94], Exp (β) = 10.57).
Conclusion: Caffeine use in young athletes is related to factors including sex and ethnicity. Given the prevalence of use, young athletes, coaches, and parents/guardians should be educated on the risks and benefits of caffeine use. Future research should focus on the potential benefits of caffeine use to athletic performance verses possible side effects in this population.

目的：本研究的目的是检查高中运动员的咖啡因摄入量和影响咖啡因使用的因素。方法：394名罗德岛高中运动员（年龄：16.8±1.27岁）完成了一项评估咖啡因摄入的横断面在线调查。采用多元逻辑回归分析和二元逻辑回归分析来表征使用和不使用与种族、年级、性别和运动等自变量之间的关系。对所有模型计算95%置信区间（CI）。所有分析的统计学意义均为p≤0.05。结果：15.5%的咖啡因使用差异与种族、年级和性别有关（R2 = 0.155），每个变量的结果都很显著。大多数女性运动员摄入咖啡因（67.4%），而男性运动员摄入咖啡因（37.8%）（p p p = 0.049）。咖啡（51%）和能量饮料（43%）是咖啡因摄入的主要来源。舞蹈、啦啦队和体操的参与者摄入咖啡因的可能性是其他运动的十倍以上（95% CI [2.28, 48.94], Exp (β) = 10.57）。结论：年轻运动员咖啡因的使用与性别和种族等因素有关。鉴于咖啡因使用的普遍性，年轻运动员、教练和家长/监护人应该了解咖啡因使用的风险和益处。未来的研究应该关注咖啡因对运动表现的潜在益处，以及对这一人群可能产生的副作用。资助：罗德岛基金会清洁竞争基金。
期刊介绍：
Journal of the International Society of Sports Nutrition (JISSN) focuses on the acute and chronic effects of sports nutrition and supplementation strategies on body composition, physical performance and metabolism. JISSN is aimed at researchers and sport enthusiasts focused on delivering knowledge on exercise and nutrition on health, disease, rehabilitation, training, and performance. The journal provides a platform on which readers can determine nutritional strategies that may enhance exercise and/or training adaptations leading to improved health and performance.
