Use of Caffeine-Containing Energy Drinks by Japanese Middle School Students: A Cross-Sectional Study of Related Factors. Nutrients 2023; 15:nu15051275. [PMID: 36904274 PMCID: PMC10004827 DOI: 10.3390/nu15051275] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2023] [Revised: 03/01/2023] [Accepted: 03/02/2023] [Indexed: 03/08/2023] Open
Abstract
Excessive consumption of caffeine negatively affects individuals' health. Therefore, we studied the use of energy drinks and the conditions associated with it among Japanese secondary school students. Participants were 236 students in grades 7-9 who completed anonymous questionnaires at home in July 2018. We measured the basic attributes and dietary, sleeping, and exercise habits. We used Chi-squared tests to compare differences between users and non-users of energy drinks. Logistic regression analyses were used to elucidate the complex association between the variables. The results showed that boys were more willing to consume energy drinks than girls. The reasons were 'feeling fatigued', 'needing to stay awake', 'for curiosity', and 'to quench one's thirst'. Among boys, the following were associated with the use of EDs. Buying their own snacks , not understanding nutritional labels on foods, high caffeinated beverage intake, late bed-times on weekdays, always waking up at about the same time, and weight. Health guidance is needed to prevent overconsumption and dependence on energy drinks. The cooperation of parents and teachers is needed to achieve these goals.

Relationships between constituents of energy drinks and beating parameters in human induced pluripotent stem cell (iPSC)-Derived cardiomyocytes. Food Chem Toxicol 2021; 149:111979. [PMID: 33450301 DOI: 10.1016/j.fct.2021.111979] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2020] [Revised: 01/05/2021] [Accepted: 01/06/2021] [Indexed: 12/24/2022]
Abstract
Consumption of energy drinks has been associated with adverse cardiovascular effects; however, little is known about the ingredients that may contribute to these effects. We therefore characterized the chemical profiles and in vitro effects of energy drinks and their ingredients on human induced pluripotent stem cell (iPSC)-derived cardiomyocytes, and identified the putative active ingredients using a multivariate prediction model. Energy drinks from 17 widely-available over-the-counter brands were evaluated in this study. The concentrations of six common ingredients (caffeine, taurine, riboflavin, pantothenic acid, adenine, and L-methionine) were quantified by coupling liquid chromatography with a triple quadrupole mass spectrometer for the acquisition of LC-MS/MS spectra. In addition, untargeted analyses for each beverage were performed with a platform combining LC, ion mobility spectrometry and mass spectrometry (LC-IMS-MS) measurements. Approximately 300 features were observed across samples in the untargeted studies, and of these ~100 were identified. In vitro effects of energy drinks and some of their ingredients were then tested in iPSC-derived cardiomyocytes. Data on the beat rate (positive and negative chronotropy), ion channel function (QT prolongation), and cytotoxicity were collected in a dilution series. We found that some of the energy drinks elicited adverse effects on the cardiomyocytes with the most common being an increase in the beat rate, while QT prolongation was also observed at the lowest concentrations. Finally, concentration addition modeling using quantitative data from the 6 common ingredients and multivariate prediction modeling was used to determine potential ingredients responsible for the adverse effects on the cardiomyocytes. These analyses suggested theophylline, adenine, and azelate as possibly contributing to the in vitro effects of energy drinks on QT prolongation in cardiomyocytes.

Abstract
INTRODUCTION The wide range of non-alcoholic drinks are currently grouped as soft (carbonated), sports, and energy drinks, and all of them have a high sugar content, along with their known risk of obesity. Their consumption is increasing and in inadvisable circumstances also an elevated health risk. The real consumption of sports and energy drinks is not well known. OBJECTIVE To determine the habits and consumption of soft, sports, and energy drinks in adolescents. MATERIAL AND METHODS A descriptive, cross-sectional study was performed in which questionnaires were obtained from 4769 schoolchildren from 13-18 years-old from Sabadell, Barcelona, Spain. RESULTS The prevalence of consuming soft drinks was observed in 92.9% of the adolescents, and was predominantly done during leisure time, during meals, or any time during the day. In sports it was 61.7%, mainly on practising the sport and in leisure time. In energy drinks, it was 49.2%, mainly in leisure time (they were mixed with alcohol in 49%) and on practising sport. The simultaneous consumption of the three types was 38%, and soft drinks were the most common. DISCUSSION A description is presented on the consumption of sports drinks, normally included as soft drinks, as well as the simultaneous consumption of the three types of drinks, and the time in which they are consumed. We have a diagnostic tool of consumption of these drinks by adolescents in our setting that will enable us to design and evaluate educational interventions in order to make the adolescent population and their families aware.

Abstract
INTRODUCTION Mortality and morbidity rates related to prescription opioid analgesics have been rising in North America and may be a gateway to the nonmedical use of prescription opioids (NUPO). The purpose of this study was to explore correlates of NUPO in the adolescent population given the scarce literature in this area. METHODS Cross-sectional data from 10,163 middle- and high-school students (15.1 ± 1.8 years old; 57.0% female; 55.6% White ethnic background) in Ontario were derived from the 2017 Ontario Student Drug Use and Health Survey. Potential correlates of NUPO in the past year included sociodemographic, behavioral, parental, and school characteristics. RESULTS Overall prevalence of NUPO was 10.7%. In the final multivariable model, NUPO was significantly associated with 8 of the 21 correlates examined. Students who used prescription opioids nonmedically were of black, South Asian, and "other" ethnic backgrounds (OR 2.83, OR 1.77, and OR 1.67, respectively); reported a lower subjective socioeconomic status (OR 0.92), lower parental support (OR 0.90), and lower academic performance (OR 0.86); met physical activity recommendations (OR 1.48); consumed energy drinks (OR 1.42); smoked tobacco cigarettes (OR 2.33); and used cannabis (OR 1.84). CONCLUSIONS Findings from this study show a wide variety of correlates of NUPO among Canadian adolescents, and highlight the need for further research and the value in targeted prevention and multi-level intervention programs for NUPO in this population.

Abstract
The present study examined the national prevalence and distribution of adolescent use of caffeinated energy drinks, assessing variations in sociodemographic characteristics, personality traits, lifestyles, and patterns of alcohol and caffeine use. A cross-sectional survey was conducted in May 2014, using a nationally representative sample of 1,032 U.S. early (aged 13-15; n = 602) and middle adolescents (aged 16-17; n = 430). Nearly two thirds of teens reported ever using energy drinks; 41% had done so recently, that is, in the past 3 months. Middle adolescents reported higher prevalences of both lifetime and recent use of energy drinks than early adolescents. Common situational contexts for use (e.g., compensating for lack of sleep or playing sports) differed by both gender and age cohort. In hierarchical logistic regression analyses, gender and geographic region significantly predicted both lifetime and recent use for early adolescents only, whereas age and race were significant predictors only for middle adolescents. For both age cohorts, odds of both lifetime and recent use increased with sensation-seeking score, lifetime alcohol use, and recent caffeinated soft drink use. Among early adolescents, grade point average predicted lifetime use only, whereas coffee and caffeine pill use predicted recent use only. Among middle adolescents, impulsivity and past sports participation predicted lifetime but not recent use. Our findings show that adolescent energy drink use is widespread and varies as a function of demographic, psychosocial, lifestyle, and substance use characteristics. Future research is needed to assess whether differences between early and middle adolescent use patterns are primarily developmental or cohort effects. (PsycINFO Database Record

Sympatho-adrenergic activation by endurance exercise: Effect on metanephrines spillover and its role in predicting athlete's performance. Oncotarget 2018; 9:15650-15657. [PMID: 29643999 PMCID: PMC5884654 DOI: 10.18632/oncotarget.24584] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2017] [Accepted: 02/20/2018] [Indexed: 11/25/2022] Open
Abstract
Background The sympatho-adrenergic activation during exercise is implicated in many cardiovascular respiratory and metabolic adaptations which have been thought to partially explain the different levels of performance observed between trained and untrained subjects. To date, no evidence exists about the association between competition performance and markers of “acute stress response”. We designed this study to investigate; (i) the acute sympatho-adrenergic activation during endurance exercise in recreational runners by measuring plasma levels of free metanephrine (MN) and normethanephrine (NMN) before and after a half-marathon run; (ii) the association between the metanephrines levels and the running time. Methods 26 amateur runners (15 males, 11 females) aged 30 to 63 years were enrolled. The quantification of MN and NMN was performed by LC-MS/MS. Anthropometric ergonomic and routine laboratory data were recorded. Statistical analyses included paired T-test, univariate and multivariate regressions. Results The post-run values of MN and NMN displayed a nearly 3.5 and 7 fold increase respectively compared to the baseline values (p < 0.0001 for both). NMN pre-run values and pre/post run delta values showed a significant direct and inverse association (p = 0.021 and p = 0.033, respectively) with running performance. No correlations were found for MN values. Conclusion NMN is a reliable marker of sympatho-adrenergic activation by exercise and can predict endurance performance in the individual athlete. Adaptation phenomenon occurring not only in the adrenal medulla might represent the biological mechanism underlying this association. Further studies on sympatho-adrenergic activation, competition performance and training status should contemplate the measurement of these metabolites instead of their unstable precursors.

Abstract
Intense exercise may cause heart remodeling to compensate increases in blood pressure or volume by increasing muscle mass. Cardiac changes do not involve only the left ventricle, but all heart chambers. Physiological cardiac modeling in athletes is associated with normal or enhanced cardiac function, but recent studies have documented decrements in left ventricular function during intense exercise and the release of cardiac markers of necrosis in athlete’s blood of uncertain significance. Furthermore, cardiac remodeling may predispose athletes to heart disease and result in electrical remodeling, responsible for arrhythmias. Athlete’s heart is a physiological condition and does not require a specific treatment. In some conditions, it is important to differentiate the physiological adaptations from pathological conditions, such as hypertrophic cardiomyopathy, arrhythmogenic dysplasia of the right ventricle, and non-compaction myocardium, for the greater risk of sudden cardiac death of these conditions. Moreover, some drugs and performance-enhancing drugs can cause structural alterations and arrhythmias, therefore, their use should be excluded.

Abstract
Globally, the popularity of energy drinks is steadily increasing. Scientific interest in their effects on cardiovascular and cerebrovascular systems in humans is also expanding and with it comes a growing number of case reports of adverse events associated with energy drinks. The vast majority of studies carried out in the general population report effects on blood pressure and heart rate. However, inconsistencies in the current literature render it difficult to draw firm conclusions with regard to the effects of energy drinks on cardiovascular and cerebrovascular variables. These inconsistencies are due, in part, to differences in methodologies, volume of drink ingested, and duration of postconsumption measurements, as well as subject variables during the test. Recent well-controlled, randomized crossover studies that used continuous beat-to-beat measurements provide evidence that cardiovascular responses to the ingestion of energy drinks are best explained by the actions of caffeine and sugar, with little influence from other ingredients. However, a role for other active constituents, such as taurine and glucuronolactone, cannot be ruled out. This article reviews the potentially adverse hemodynamic effects of energy drinks, particularly on blood pressure and heart rate, and discusses the mechanisms by which their active ingredients may interact to adversely affect the cardiovascular system. Research areas and gaps in the literature are discussed with particular reference to the use of energy drinks among high-risk individuals.
