Sample characteristics (n = 1746).

While studies from high-income countries have shown an association between adolescents’ poor dietary habits and a lack of quality sleep, there is a dearth of similar data from developing nations. This study intends to investigate the relationship between the consumption of carbonated soft drinks and fast food and sleep disturbances linked to anxiety in school-going adolescents in Bangladesh. The data used for this study came from the 2014 Bangladesh Global School-based Health Survey. Information of 1746 adolescents was utilized in this current analysis. Multivariable logistic regression analyses were used to identify the associations of interest. In this sample, sleep disturbance associated with anxiety was prevalent at 3.5%. Approximately half of the adolescents (44.4%) consumed soft drinks for one or more occurrences per day during the past 30 days, and 51.2% consumed fast food on one or more days during the past 7 days. Results show that the odds of sleep disturbance associated with anxiety were higher among adolescents who consumed soft drinks (odds ratio [OR] = 2.43; 95% confidence interval [CI] = 1.15–5.15) and fast food (OR = 2.34; 95% CI = 1.01–5.43) than their respective counterparts after controlling for other covariates, such as age, gender, grade, feeling hungry, engagement in physical violence, physical activity, being bullied, having close friends, peer support, and parental attachment. Sleep disturbance due to anxiety is more common among Bangladeshi school-aged adolescents who consume carbonated beverages or fast food. Further longitudinal studies are necessary to validate or refute our findings and investigate relevant explanations.

尽管高收入国家的相关研究已证实青少年不良膳食习惯与睡眠质量低下存在相关性，但发展中国家的同类研究数据仍较为匮乏。本研究旨在探讨孟加拉国在校青少年饮用碳酸软饮料（carbonated soft drinks）、食用快餐与焦虑相关睡眠障碍之间的关联。本研究数据来源于2014年孟加拉国全球校园健康调查（Bangladesh Global School-based Health Survey），最终纳入1746名青少年的信息开展本次分析。本研究采用多变量logistic回归分析（multivariable logistic regression analyses）识别目标关联。在本次研究样本中，伴焦虑症状的睡眠障碍患病率为3.5%。约44.4%的青少年在过去30天内每日饮用软饮料至少1次，51.2%的青少年在过去7天内至少有1天食用快餐。分析结果显示，在控制年龄、性别、年级、饥饿感、躯体暴力经历、体力活动、受欺凌情况、亲密好友拥有情况、同伴支持及亲子依恋等其他混杂变量后，饮用软饮料的青少年（比值比[OR]=2.43；95%置信区间[CI]=1.15–5.15）与食用快餐的青少年（OR=2.34；95%CI=1.01–5.43）出现伴焦虑症状的睡眠障碍的风险均显著高于其对应对照组。研究表明，孟加拉国在校青少年若饮用碳酸饮料或食用快餐，其伴焦虑症状的睡眠障碍发生率更高。后续仍需开展纵向研究以验证或推翻本研究结论，并探究其相关机制。
