Background

Nutrition is an important predictor of an athlete's performance. It is more important for particularly those athletes who are in the growing stage (adolescents). This study aimed to assess their current level of knowledge, attitude, and practices (KAP) of nutrition and to predict potential factors impacting their level of these KAP.

Methods

A cross-sectional study was conducted among adolescent trainee athletes selected conveniently from 11 sports departments (e.g. cricket, football, hockey, etc.) of Bangladesh Krira Shikkha Protishtan (BKSP). A semi-structured interviewer-administered questionnaire was used for data collection. Anthropometric measurements (e.g. height, weight, BMI, BF %) were taken using appropriate methods. The data were analyzed using R (v3.6.1) and Python Jupyter Notebook. Descriptive statistics, t-test, analysis of variance (ANOVA), and logistic regression were used to determine the relationship between dependent and independent variables.

Results

A total number of 260 participants were enrolled in this study, most of them (86%) were male. Their mean age was 15.50 ± 1.83 ranging from 12-19 years. More than half of the participants had good nutrition knowledge (n = 149, 57.3%). Fifty-seven percent of participants had a positive attitude (n = 146) and 57.69% (n = 150) had a good level of practices regarding nutrition. Age (p = 0.007), gender (p = 0.004), department of training (p = 0.0034), and duration of sports training (p = 0.004) of participants were significantly associated with knowledge, while only age and BMI were significantly associated with practices. Athletes with less body fat were more likely to have good nutrition practice behavior (AOR 0.895; 95% CI 0.83, 0.96; p < 0.05) and nutrition knowledge was positively associated with nutrition practice (AOR 2.335; 95% CI 1.405, 3.88; p = 0.001).

Conclusion

Knowledge, attitude, and practices level observed among many of our participants was satisfactory. Previous nutrition training was found as a potentially modifiable factor of good nutrition knowledge and good nutrition knowledge was found to be a predictor of good practice score. Thus, it is necessary to provide appropriate nutrition information to adolescent athletes through proper educational training and intervention on a regular basis.

青少年体育学员营养知识、态度和实践的决定因素：孟加拉国的横断面研究

背景

营养是运动员表现的重要预测指标。特别是对于那些处于成长阶段的运动员（青少年）来说更为重要。本研究旨在评估他们当前的营养知识、态度和实践 (KAP) 水平，并预测影响他们这些 KAP 水平的潜在因素。

方法

对从孟加拉国 Krira Shikkha Protishtan (BKSP) 的 11 个体育部门（如板球、足球、曲棍球等）方便地挑选出来的青少年学员运动员进行了一项横断面研究。使用半结构化的采访者管理的问卷进行数据收集。使用适当的方法进行人体测量（例如身高、体重、BMI、BF %）。使用 R (v3.6.1) 和 Python Jupyter Notebook 分析数据。描述性统计、t 检验、方差分析 (ANOVA) 和逻辑回归用于确定因变量和自变量之间的关系。

结果

共有 260 名参与者参加了这项研究，其中大多数 (86%) 是男性。他们的平均年龄为 15.50 ± 1.83，介于 12-19 岁之间。超过一半的参与者具有良好的营养知识（n = 149, 57.3%）。57% 的参与者持积极态度（n = 146），57.69%（n = 150）在营养方面有良好的实践水平。参与者的年龄 (p = 0.007)、性别 (p = 0.004)、训练部门 (p = 0.0034) 和运动训练持续时间 (p = 0.004) 与知识显着相关，而只有年龄和 BMI 与知识显着相关。实践。体脂较少的运动员更有可能有良好的营养实践行为（AOR 0.895；95% CI 0.83, 0.96；p < 0.05），营养知识与营养实践呈正相关（AOR 2.335；95% CI 1.405, 3.88；

结论

在我们的许多参与者中观察到的知识、态度和实践水平令人满意。以前的营养培训被发现是良好营养知识的潜在可修改因素，而良好的营养知识被发现是良好实践得分的预测因素。因此，有必要通过适当的教育培训和定期干预，为青少年运动员提供适当的营养信息。
