[PMID: 38466174 DOI: 10.1080/15502783.2024.2323919] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Accepted: 02/17/2024] [Indexed: 03/12/2024] Open
Abstract
Caffeine is a popular ergogenic aid that has a plethora of evidence highlighting its positive effects. A Google Scholar search using the keywords "caffeine" and "exercise" yields over 200,000 results, emphasizing the extensive research on this topic. However, despite the vast amount of available data, it is intriguing that uncertainties persist regarding the effectiveness and safety of caffeine. These include but are not limited to: 1. Does caffeine dehydrate you at rest? 2. Does caffeine dehydrate you during exercise? 3. Does caffeine promote the loss of body fat? 4. Does habitual caffeine consumption influence the performance response to acute caffeine supplementation? 5. Does caffeine affect upper vs. lower body performance/strength differently? 6. Is there a relationship between caffeine and depression? 7. Can too much caffeine kill you? 8. Are there sex differences regarding caffeine's effects? 9. Does caffeine work for everyone? 10. Does caffeine cause heart problems? 11. Does caffeine promote the loss of bone mineral? 12. Should pregnant women avoid caffeine? 13. Is caffeine addictive? 14. Does waiting 1.5-2.0 hours after waking to consume caffeine help you avoid the afternoon "crash?" To answer these questions, we performed an evidence-based scientific evaluation of the literature regarding caffeine supplementation.

[PMID: 39368541 DOI: 10.1016/j.fct.2024.115025] [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: 07/10/2024] [Revised: 09/13/2024] [Accepted: 09/25/2024] [Indexed: 10/07/2024]
Abstract
BACKGROUND The popularity of caffeinated foods and beverages poses risks of high caffeine exposure among Chinese children and adolescents. Nevertheless, there is a lack of national assessments on their caffeine consumption. OBJECTIVE To estimate daily caffeine intake and analyze time trends among Chinese children and adolescents. METHODS The study subjects were participants of the China Health and Nutrition Survey in 2004, 2006, 2009 and 2011, and the National Food and Beverage Consumption Survey in 2014 and 2018. Caffeine content was determined using chromatographic instrument. The Monte Carlo simulation was utilized to estimate daily caffeine intake and the Kruskal-Wallis test was used to analyze differences between population characteristics. To examine yearly trends in caffeine intake from 2004 to 2018, the partial Mann-Kendall test was applied. RESULTS The median daily caffeine intake of Chinese children and adolescents was 0.17 (95%CI: 0.15-0.20) mg/kg BW/day. Main contributors were tea (55.52%), sodas (19.52%) and tea beverages (10.37%). Approximately 4.68% of individuals consumed caffeine exceeding 2.5 mg/kg BW/day. Higher caffeine intake was observed in adolescents aged 12-17 years, males, and consumers residing in northeastern China. While no significant overall yearly trends in caffeine intake were detected from 2004 to 2018, there was an increase in intake driven by beverage consumption between 2006 and 2014. CONCLUSION This study provided a national assessment of caffeine consumption among Chinese children and adolescents. Caffeinated beverages like tea, soda, and tea beverages emerged as major contributors to caffeine intake. These findings could contribute to the regulation of caffeine consumption and the promotion of healthy habits among children and adolescents.

J Affect Disord 2024:S0165-0327(24)01670-7. [PMID: 39368777 DOI: 10.1016/j.jad.2024.10.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2024] [Revised: 09/28/2024] [Accepted: 10/02/2024] [Indexed: 10/07/2024]
Abstract
BACKGROUND Previous research revealed an association between coffee consumption and depressive symptoms. However, the results differed between studies in adults and adolescents. Additionally, limited research on coffee and depressive symptoms has distinguished between black and sugar-sweetened coffee. Furthermore, few studies have examined the potential sex differences in the abovementioned association. This longitudinal study aimed to explore the associations of black and sugar-sweetened coffee consumption with subsequent depressive symptoms in adolescents while also investigating sex disparities within these associations. METHODS In this longitudinal study, 10,770 individuals completing standardized questionnaires at baseline and follow-up were included in the main analysis. The data were analyzed using generalized linear mixed-effects models, and subgroup analyses were grouped according to sex. RESULTS After adjusting for covariates and baseline depressive symptoms status, adolescents who consumed black coffee daily (OR, 1.45; 95 % CI, 1.14-1.84) had a greater risk of experiencing depressive symptoms compared with those who did not consume it or consumed it monthly. Similarly, in comparison with none or monthly consumers, those who consumed sugar-sweetened coffee weekly (OR, 1.22; 95 % CI, 1.03-1.44) and daily (OR, 1.32; 95 % CI, 1.02-1.73) demonstrated an elevated risk of having depressive symptoms. Subgroup analyses showed that black and sugar-sweetened coffee consumption was associated with depressive symptoms only in males. LIMITATIONS Self-reported data on coffee consumption and depressive symptoms. CONCLUSIONS Adolescents who consume black or sugar-sweetened coffee weekly or daily are at a higher risk of developing depressive symptoms, with this association appearing to be more pronounced in male adolescents. Future studies are needed to confirm these findings.

Abstract
Purpose: Hoarseness and voice problems are one of the chronic conditions experienced by children. The aim of this study was to investigate the prevalence of hoarseness, possible risk factors and effects of the remediation of school buildings to the prevalence of hoarseness among school children. Methods: The material was gathered from all the schools in a large city in the south of Finland and the collection method used was an e-mail survey sent to the parents of the pupils and a simultaneous survey sent to the personnel in the schools. Results: All 51 schools participated, and 5889 pupils returned the questionnaire (39%). The exposure data was obtained from two building experts who knew the repair history of the schools. A subjective estimation of the quality of the indoor air was obtained from teachers and the parents. The overall prevalence of hoarseness among pupils was 6.3%; prevalence being higher in unrepaired school buildings than in schools in a good condition or buildings with a thorough remediation. Hoarseness was associated with asthma and allergies, several respiratory symptoms, and respiratory infections. Exposure to tobacco smoke increased the risk, and consumption of caffeine containing drinks seemed to reduce the risk. Noise, stuffiness of the indoor air and microbial smells correlated strongly with the occurrence of hoarseness in a logistic regression model when controlled for age, gender, asthma, passive smoking, and caffeine consumption. Conclusions: We recommend renovations in school buildings with the aim of providing better acoustics, sufficient ventilation, and a reduction in exposure to moisture damage microbes.

Abstract
BACKGROUND Coffee is widely consumed around the world. In Japan, it is a type of "Shikohin" (consumed for flavor, not nutrition). Several medical studies have reported the beneficial effects of coffee consumption, whereas others suggest that these beneficial effects on psychological aspects are marginal. The habit of consuming large amounts of caffeine through coffee may improve short-term resilience in stressful situations and may exhaust individuals in the long term. We hypothesized that people who habitually drink high amounts of coffee would have lower resilience scores and higher acute stress responses. METHODS Adult Japanese men completed a questionnaire that included a resilience scale and Shikohin consumption habits. Experimental participants were recruited from the survey respondents and classified into three groups based on their coffee consumption per day: No Coffee, Low Coffee, and High Coffee. All participants were asked to join the Trier Social Stress Test-Online (TSST-OL). Subjective stress and salivary cortisol concentrations was measured at eight time points during the experiment. There were 16 participants in each group for the analysis (mean age = 46.10 years, SD = 12.58). RESULTS Statistical analysis showed that both subjective stress and salivary cortisol concentrations significantly increased following TSST-OL exposure. However, there were no significant differences among the groups, and the hypotheses were not supported. CONCLUSIONS This study demonstrated the effectiveness and stability of the TSST-OL. Additionally, coffee consumption habits were not significantly related to resilience scale scores or acute stress responses.

Froehner: A review and bibliometric analysis. World J Biol Psychiatry 2024; 25:353-369. [PMID: 38900601 DOI: 10.1080/15622975.2024.2369329] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/21/2024] [Revised: 05/07/2024] [Accepted: 06/13/2024] [Indexed: 06/22/2024]
Abstract
OBJECTIVE Syzygium aromaticum and Coffea canephora are acknowledged for their outstanding antioxidant, anti-inflammatory, and nerve-stimulant properties, showcasing potential in brain protection. Therefore, this study aims to quantitatively review existing literature and assess the potential of using it to formulate a herbal tea blend for managing stress and anxiety. METHODS Data was retrieved from the Scopus database, and a bibliometric analysis was performed using VOSviewer software. RESULTS Following a screening process, a total of 121 articles were identified, with S. aromaticum yielding a higher number compared to C. canephora. A detailed exploration of each plant revealed active components such as eugenol, β-caryophyllene, α-humulene, caffeine, mangiferin, and chlorogenic acids, each exhibiting stimulatory effects alongside antioxidant and anti-inflammatory properties. The neuroprotective effects were attributed to the reduction of oxidative stress and inflammation, coupled with the stimulation of neurotransmitters and hormones like dopamine, serotonin, cortisol, and adrenaline. CONCLUSIONS The review showed that these plants positively affect mood and cognition by influencing the brain's pleasure system. This suggests the need for further research to combine these plant extracts for developing 'Tenang tea', a potential herbal blend for managing stress and anxiety.

Abstract
Background and Aims Premature atrial contractions (PACs) and premature ventricular contractions (PVCs) are ectopic heart rhythm disorders with implications for cardiovascular health. This study explores the relationship between caffeine consumption and the risk of PACs and PVCs, with a focus on healthcare workers, such as doctors, nurses, pharmacists, and midwives, who often rely on caffeine to combat fatigue, especially during night shifts. Methods A thorough review was conducted through PubMed, Scopus, Google Scholar, and Web of Science, utilizing a combination of MeSH terms and keywords. Studies examining the link between caffeine consumption and PACs and PVCs, particularly in healthcare workers, were included. Results We found that caffeine shows various effects based on dosage and can impact arrhythmia risk. Individuals working long shifts, including healthcare professionals, are prone to increased caffeine intake, leading to higher cardiovascular risk. To mitigate these risks, tailored guidelines for caffeine consumption, flexible shift scheduling, and mental health support services are recommended. Promoting caffeine alternatives within healthcare institutions can be beneficial. Conclusion Although caffeine may have potential benefits, its drawbacks, particularly concerning cardiovascular health, may surpass its advantages, especially when consumed in high doses. A multidisciplinary approach is crucial for healthcare workers' well-being and quality of patient care. Further research is required to refine and support these recommendations.

Abstract
INTRODUCTION Sugar-sweetened beverage and caffeinated beverage consumption are associated with a variety of health issues among youth. Food and beverage marketing has been shown to affect youth's preferences, purchases, and consumption of marketed products. Previous research suggests that outdoor food and beverage marketing differs by community demographics, with more advertisements in lower-income communities and near schools. The purpose of this study is to examine the density of sugar-sweetened and caffeinated beverage advertisements near schools by school type (middle vs. high school) and by school-level SES. METHODS Data are from the Outdoor Measuring and Evaluating the Determinants and Influence of Advertising (MEDIA)study, which documented and described all outdoor food and beverage advertisements near 47 middle and high schools in 2012. Beverage advertisements were categorized as: sugar-sweetened/caffeinated, sugar-sweetened/non-caffeinated, non-sugar-sweetened/caffeinated, or non-sugar-sweetened/non-caffeinated. Schools were categorized by type (middle vs high) and by SES as determined by the percentage of students qualifying for free or reduced-price lunch. Bootstrapped non-parametric Mann-Whitney U tests compared the number of advertisements in each category by school type and school-level SES (higher vs lower). RESULTS Compared to schools with higher SES, schools with lower SES had significantly more advertisements for sugar-sweetened/non-caffeinated beverages (Medianlow = 28.5 (IQR 17-69), vs Medianhigh = 10.5 (IQR 4-17) (p = 0.002)., sugar-sweetened non-caffeinated (Medianlow = 46 (IQR 16-99) vs Medianhigh = 13.5 (IQR 6-25), p = 0.002), -sugar-sweetened caffeinated (Medianlow = 12 (IQR 8-19) vs Medianhigh = 6 (IQR 2-8), p = 0.000), and non-sugar-sweetened non-caffeinated (Medianlow = 30 (IQR 13-65) vs Medianhigh = 14 (IQR 4-29), p = 0.045).There were no significant differences by school type. CONCLUSION This study adds to the literature demonstrating pervasive marketing of unhealthy products in lower-income communities. Disproportionate exposure to sugar-sweetened and caffeinated beverage advertisements in lower-income communities may contribute to the disparities in associated health outcomes by economic status.

Abdoli F, Davoudi M, Momeni F, Djafari F, Dolatshahi B, Hosseinzadeh S, Aliyaki H, Khalili Z. Estimate the prevalence of daily caffeine consumption, caffeine use disorder, caffeine withdrawal and perceived harm in Iran: a cross-sectional study. Sci Rep 2024; 14:7644. [PMID: 38561480 PMCID: PMC10984976 DOI: 10.1038/s41598-024-58496-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2023] [Accepted: 03/29/2024] [Indexed: 04/04/2024] Open
Abstract
One of the informal diagnoses in DSM-5 is Caffeine Use Disorder (CUD). CUD and high levels of caffeine consumption could impact mental health conditions. This study aimed to estimate the prevalence of CUD, caffeine consumption, caffeine-related harms, and related psychiatric symptoms in Iran. A cross-sectional survey with a convenience sample of 1228 adults were conducted in Iran. Caffeine consumption was assessed across 20 products in Iran. Caffeine Use Disorder Questionnaire (CUDQ), Caffeine Withdrawal Symptoms Questionnaire (CWSQ), 14-item Caffeine-related Harm Screening (CHS), and Symptom Checklist-25 (SCL-25) were used in the present study. We used SPSS (desktop version 26.0) to analyze the data using descriptive statistics, chi-square, and the least significant difference (LSD) post hoc test. The daily average caffeine consumption was 146.67 mg. The prevalence of CUD and caffeine withdrawal (C.W.) were estimated at 19.5% and 46.62%, respectively. Also, 12.9% of responders received CUD and C.W.s simultaneously. The prevalence of CUD was higher in men than females (25.08% vs. 13.93%). 95% of participants (n = 1166) reported using at least one caffeine product yesterday. Moreover, the most reported caffeine-related harms were the desire for sugar (42.9%), insomnia (39.3%), and caffeine dependence (38.3%). Age significantly correlates with CUD (- 0.07) and daily caffeine intake (0.08). Moreover, all SCL-90 subscales had a significant correlation with daily caffeine intake. Finally, responders at younger ages reported higher levels of CUD and caffeine consumption than older adults(P < 0.05). High rates of C.W. and CUD in the Iranian population suggest that it is necessary to develop evidence-based treatments.

Problematic coffee use and associated factors among medical and health science students in Dilla University, Ethiopia. SAGE Open Med 2024; 12:20503121241235455. [PMID: 38533201 PMCID: PMC10964470 DOI: 10.1177/20503121241235455] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Accepted: 02/08/2024] [Indexed: 03/28/2024] Open
Abstract
Objective Coffee holds a cherished place in Ethiopian culture, its consumption among students raises concerns despite its perceived benefits for alertness and productivity. Moderate caffeine intake remains unproblematic, but exceeding 400 mg daily can trigger detrimental health effects such as fatigue, memory impairment, and even attention-deficit disorder. Research on problematic coffee use among young adults, specifically Ethiopian students, remains limited, hindering our understanding of its potential scope and impact. To address this knowledge gap, researchers at Dilla University, Ethiopia, undertook a comprehensive study in 2022, focusing on the university's student population. This investigation holds significant potential to unveil the previously obscured landscape of excessive coffee consumption in this demographic and inform future research and potential interventions. Methodology An institutional-based cross-sectional study design was conducted in August-July, 2022. To measure problematic coffee use, this study used the Diagnostic Statistical Manual five criteria for substance use disorder. Those who scored >2 out of 11 criteria were considered to have problematic coffee use. To measure a significant association between the outcome and independent variable, a multivariable logistic regression analysis at p < 0.05 and 95% confidence interval was employed. Result This study included 414 respondents. More than half of the respondents, 347 (59.7%) were male. Out of all respondents, 182 (44.0%) had a boy/girlfriend. Nearly half of the respondents, 218 (52.7%) were orthodox, Christian religion followers. According to this study's findings, 137 (33.1%) respondents were considered to have problematic coffee use. Multivariable logistic regression analysis showed that 5-10 years duration of coffee use (AOR = 4.62, 95% CI: 2.96-7.85; p = 0.001), start to use coffee before joining university (AOR = 2.977, 95% CI: 1.332-6.653; p = 0.008) and 6-9 cups of daily coffee use (AOR = 3.26, 95% CI: 2.14-5.89; p = 0.00) were associated with problematic coffee use. Conclusion This study showed that one-third of the respondents had problematic coffee use. The starting point, duration, and amount of use had a strong association with problematic coffee use. Hence, focusing on addressing the mental health challenges associated with problematic/excessive coffee consumption among higher education students is advisable. Additionally, promoting awareness of problematic/excessive coffee use and its potential remedies is recommended.

Abstract
BACKGROUND AND OBJECTIVES While the health promoting effects of green tea polyphenols have been identi-fied among adult, research on children is scarce probably due to safety concerns about caffeine. This study aims to evaluate the safety of decaffeinated green tea polyphenols (DGTP) supplementation in girls with obesity and lay the foundation for its application in children population. METHODS AND STUDY DESIGN This 12-week randomized, double-blinded, parallel-controlled trial was performed among 62 girls with obesity aged 6 to 10 years old. Participants were allocated to take 400 mg/d DGTP (DGTP group, n = 31) or isodose placebo (Control group, n = 31) at random. Anthropometric measurements and biochemical parameters including hepatic and renal function indicators, serum minerals concentrations, and routine blood parameters, were measured at baseline and the end of this trial. DGTP intake diary was required for each participant to record any abnormal reactions. RESULTS After the 12-week supplementation, compared to Control group, the uric acid concentration in DGTP group showed a significant decrease (-48.0 ± 83.2 vs -0.01 ± 69.1, μmol/L), within the normal range. Regarding other biochemical indicators, there were no significant differences in changed values between the two groups. Throughout the trial, no adverse effects were reported in either group. CONCLUSIONS This study indicated that the supplementation of 400 mg/d DGTP for 12 weeks had no adverse health effects in girls with obesity, providing evidence for the DGTP adoption in children research.

Abstract
The results from studies on relationship between caffeine intake and risk of anxiety remains controversial, so we conducted a meta-analysis to summarize the evidence about the association between caffeine intake and risk of anxiety. Relevant articles were identified by researching PubMed, Web of Science, Cochrane library, Embase, CNKI, WANFANG DATA, SinoMed and VIP from the inception to December, 2022. Three investigators independently sifted through the literature, extracted the data, and evaluated the quality of the included studies based on predetermined selection criteria and assessed articles with Risk of bias assessment tool for Cochrane systematic reviews and analytical cross-sectional study quality assessment tool from JBI PACES. After assessing the quality of the literature, meta-analysis was performed using Revman 5.4 and Stata 12.0. Data were obtained from eight articles, and 546 participants from 14 studies in eight articles from healthy populations were included in the caffeine-anxiety analyses. As the scales used to assess anxiety vary in the literature, we chose standardized mean difference as the outcome indicator. In terms of overall effect, the results of the meta-analysis showed that caffeine intake increased the risk of anxiety [SMD = 0.94, 95% Cl = (0.28, 1.60), p < 0.05]. After suspecting that dose size might be responsible for the heterogeneity by sensitivity analysis, we performed subgroup analysis according to dose size and found that low-dose caffeine intake moderately increased the risk of anxiety [SMD = 0.61, 95%Cl = (0.42, 0.79), p < 0.05], whereas high-dose caffeine intake had a highly significant increase in the risk of anxiety [SMD = 2.86, 95%Cl = (2.50, 3.22), p < 0.05]. The results confirm that caffeine intake is associated with an elevated risk of anxiety in healthy individuals without psychiatric disorders, especially when the intake dose is greater than 400 mg.

Abstract
OBJECTIVE Panic attacks are an impairing mental health problem that affects 11% of adults every year. Current criteria describe them as occurring without warning, despite evidence suggesting individuals can often identify attack triggers. We aimed to prospectively explore qualitative and quantitative factors associated with the onset of panic attacks. RESULTS Of 87 participants, 95% retrospectively identified a trigger for their panic attacks. Worse individually reported mood and state-level mood, as indicated by Twitter ratings, were related to greater likelihood of next-day panic attack. In a subsample of participants who uploaded their wearable sensor data (n = 32), louder ambient noise and higher resting heart rate were related to greater likelihood of next-day panic attack. CONCLUSIONS These promising results suggest that individuals who experience panic attacks may be able to anticipate their next attack which could be used to inform future prevention and intervention efforts.

Abstract
This study explored the effect of naringin (NAR) on HGPRT1 deficiency and hyperuricemia through NOS-cAMP-PKA and BDNF/TrkB signaling pathways induced by caffeine (CAF) and KBrO3 in a rat model. Sixty-three adult male albino rats were randomly assigned into nine (n = 7) groups. Group I: control animals, Group II was treated with 100 mg/kg KBrO3 , Group III was treated with 250 mg/kg CAF, Group IV was treated with 100 mg/kg KBrO3 + 250 mg/kg CAF, Group V was administered with 100 mg/kg KBrO3 + 100 mg/kg haloperidol, Group VI was administered with 100 mg/kg KBrO3 + 50 mg/kg NAR, Group VII was administered with 500 mg/kg CAF + 50 mg/kg NAR, and Group VIII was administered with 100 mg/kg KBrO3 + 250 mg/kg CAF + 50 mg/kg NAR. Finally, group IX was treated with 50 mg/kg NAR. The exposure of rats to KBrO3 and CAF for 21 days induced renal dysfunction linked with Lesch-Nyhan disease. NAR obliterated renal dysfunction linked with Lesch-Nyhan disease by decreasing uric acid, renal malondialdehyde level, inhibiting the activities of arginase, and phosphodiesterase-51 (PDE-51) with corresponding upregulation of brain derived-neurotrophic factor and its receptor (BDNF-TrkB), Bcl11b, HGPRT1, and DARPP-32. Additionally, renal failure related to Lesch-Nyhan disease was remarkably corrected by NAR as shown by the reduced activities of AChE and enzymes of ATP hydrolysis (ATPase, AMPase, and ADA) with affiliated increase in the NO level. This study therefore validates NAR as nontoxic and effective chemotherapy against kidney-related Lesch-Nyhan disease by mitigating effects of toxic food additives and enzymes of ATP-hydrolysis via NOS-cAMP-PKA and BDNF/TrkB signaling pathways.

Abstract
Caffeine, which shares consubstantial structural similarity with purine adenosine, has been demonstrated as a nonselective adenosine receptor antagonist for eliciting most of the biological functions at physiologically relevant dosages. Accumulating evidence supports caffeine's beneficial effects against different disorders, such as total cardiovascular diseases and type 2 diabetes. Conversely, paradoxical effects are also linked to caffeine ingestion in humans including hypertension-hypotension and tachycardia-bradycardia. These observations suggest the association of caffeine action with its ingested concentration and/or concurrent interaction with preferential molecular targets to direct explicit events in the human body. Thus, a coherent analysis of the functional targets of caffeine, relevant to normal physiology, and disease pathophysiology, is required to understand the pharmacology of caffeine. This review provides a broad overview of the experimentally validated targets of caffeine, particularly those of therapeutic interest, and the impacts of caffeine on organ-specific physiology and pathophysiology. Overall, the available empirical and epidemiological evidence supports the dose-dependent functional activities of caffeine and advocates for further studies to get insights into the caffeine-induced changes under specific conditions, such as asthma, DNA repair, and cancer, in view of its therapeutic applications.

Abstract
Although there is an established connection between diet and mental health, the relationship between diet and dental anxiety has not been examined yet. The purpose of this study was to fill this gap by assessing the association between diet quality, mental distress, and dental anxiety. The data was collected through an anonymous Google Forms survey. The survey consisted of a modified version of the validated Food-Mood Questionnaire and the Modified Dental Anxiety Scale with questions about demographics, dental health, and dental health anxieties. Data collection was performed over seven months, from April to October 2021. Data were analyzed using Pearson's correlation coefficient in SPSS version 25.0 and STATA 17 for sample size calculation, data processing and regression analyses. A total of 506 responses were collected. Our data verified that diet quality modulates dental anxiety. Women exhibited a stronger link with dental anxiety than men (p < 0.01). Consumption of sugary foods was associated with different attributes of dental anxiety (p < 0.01). Low-quality energy-dense foods and dairy were associated with dental anxiety, whereas caffeine, meat, nuts, and green leafy vegetables produced a negative correlation. This cross-sectional study provides proof of concept that dietary patterns are potentially associated with dental anxiety.

Abstract
Depression and cancer are both prevalent diseases worldwide. Numerous cancer patients experience psychological illnesses, especially depression, following a malignancy's dismal prognosis. Although some research has suggested that caffeine may be protective against depressive symptoms, it is still unclear how caffeine and cancer patients are related. Thus, we hypothesized that moderate daily caffeine intake may reduce the risk of depression in both the cancer and noncancer populations. Data were extracted and combined from the National Health and Nutrition Examination Survey from 2007 to 2016. After controlling for potential confounding factors, interaction effects analysis was used to clarify the interaction between caffeine and cancer on depressive symptoms. Linear regression analysis and restricted cubic splines were used to further analyze the relationship between caffeine and depression in cancer and noncancer populations. A total of 24,145 participants were included in the analysis. In the noncancer population, the quartile 3 group of caffeine intake showed a negative association between caffeine intake and Patient Health Questionnaire-9 (PHQ-9) scores (β = -0.23, 95% confidence interval, -0.45 to -0.01; P = .041). No association between caffeine intake and PHQ-9 scores was observed in the cancer population. In both cancer and noncancer populations, restricted cubic splines indicated a nonlinear trend between caffeine and PHQ-9 scores, with the lowest PHQ-9 scores when caffeine intake was 119.52 mg. In the noncancer population, moderate daily caffeine intake (quartile 3 group; range, 119.5-236.5 mg) was associated with reduced depressive symptoms, whereas in the cancer population, no association was found between caffeine intake and depression.

Abstract
Introduction Caffeine is a psychoactive stimulant frequently found in coffee, tea, energy drinks, and some medications. Various mental health challenges, including stress, anxiety, and depression, commonly affect college students. Moreover, an individual's mental and physical health can be significantly impacted by stress, anxiety, and depression. However, the impact of caffeine on mental health, particularly its association with depressive and anxiety symptoms, remains inconclusive. Thus, this study aimed to evaluate the amount of caffeine consumed by university students and its association with depression, anxiety, and stress levels. Material and method This cross-sectional study was performed on Taibah University students in Medina from both health-related and non-health-related colleges. We used a self-administrated questionnaire composed of four sections: the informed consent section; sociodemographic information; the Depression, Anxiety, and Stress Scale (DASS-21), which assessed the depression, anxiety, and stress levels; and a caffeine-measuring questionnaire, which reported daily caffeine intake in milligrams per day. Result This cross-sectional study examined a 520 convenience sample of Taibah University students with an age range from 17 to 29 years. The majority of the participants were single (95.2%), most of them were female (73.8%), and slightly more than half (51.5%) were recruited from health-related colleges. According to the study's DASS-21 score results, 45.8% of the students had extremely severe stress, 61% had extremely severe anxiety, and 51% had extremely severe depression. The most frequently reported sources of daily caffeine among the participants were Arabic coffee (69.6%), specialty coffee (57.5%), black tea (56.3%), cola (48.7%), and regular coffee (48.5%). The overall daily amount of consumed caffeine ranged from zero to 4276.7 mg/oz. However, no significant association was found between the severity of the DASS-21 score and the daily consumption of caffeine among Taibah University students. Conclusion Our study shows no significant association between the severity of depression, anxiety, and stress and daily caffeine consumption among university students. This proves the opposite of the theory that high levels of caffeine consumption can be correlated to high levels of depression, stress, and anxiety.

Psychiatry Res 2023; 326:115307. [PMID: 37352747 DOI: 10.1016/j.psychres.2023.115307] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/07/2023] [Revised: 06/10/2023] [Accepted: 06/12/2023] [Indexed: 06/25/2023]
Abstract
Accumulating evidence has reported the associations of coffee consumption with physical conditions and mortality, but the associations with mental disorders were limited. The objective of this study was to examine the associations of coffee consumption with incident depression and anxiety, and to assess whether the associations differed by coffee subtypes (instant, ground, and decaffeinated coffee) or additives (milk, sugar-sweetened, and artificial-sweetened). In this prospective cohort study, we utilized data from the UK Biobank and included a total of 146,566 participants who completed the touchscreen questionnaire at baseline between 2006 and 2010. During the follow-up, incident depression and anxiety were measured in 2016 using the Patient Health Questionnaire (PHQ)-9 and the Generalised Anxiety Disorder Assessment (GAD)-7, respectively. Multivariable-adjusted logistic regression models and restricted cubic splines were used to assess the associations. Approximately 80.7% of participants reported consuming coffee, and most drank 2 to 3 cups per day (41.2%). We found J-shaped associations between coffee consumption and both incident depression and anxiety, with the lowest risk of the mental disorders occurring at around 2-3 cups per day. Results were similar for participants who drank 2-3 cups of ground coffee, milk-coffee, or unsweetened coffee. Our findings highlight that 2-3 cups of coffee consumption could be recommended as part of a healthy lifestyle to improve mental health.

Abstract
How differently male and female responds in a stressful situation is a matter of curiosity. Apart from curiosity, this opens a new arena to the synthesis of personalized/individualized medications. Here, we used zebrafish, a suitable experimental animal model to study stress and anxiety. We evaluated the differential responses in adult male and female zebrafish on the acute exposure of three different stressors: Caffeine (100mg/L), Conspecific alarm substance (3.5ml/L), and sight of sympatric predators (Leaf fish and Snakehead) with the help of two different behavioural paradigms (Novel tank test & Predator exposure). Behavioural responses were captured over 6minutes and quantified using Smart 3.0. Male zebrafish were found to be more responsive to caffeine treatment. Conspecific alarm substance-challenged males and females showed robust alarm reactions whereas females were found to be more prone to it. Female zebrafish showed statistically significant aversion to the visual representation of sympatric predators. Taken together, each stressor induced differential responses in male and female zebrafish.

Abstract
This cross-sectional study examines the association between coffee and caffeine consumption and depressive symptoms in postpartum women. In total, 821 postpartum women who met the study's inclusion criteria were interviewed. Data were extracted from the 2007-2018 National Health and Nutrition Examination Survey. Coffee consumption and 11 confounding variables were considered and analyzed as baseline data. Weighted logistic regression models were constructed by adjusting the variables, and the odds ratios of total coffee, caffeinated coffee, and decaffeinated coffee were assessed for their impact on depression status. In addition, subgroup analyses were conducted according to race, breastfeeding status, and postpartum period. The results show that generic coffee and caffeinated coffee intake have a potentially protective effect in postpartum women. Drinking more than three cups of caffeinated coffee may lower the risk of postpartum depression, particularly in the 1-2 year postpartum period and in non-breastfeeding women. The association between decaffeinated coffee consumption and postpartum depression remains unclear.

Abstract
This paper reviews the principles identified in analytic neuroscience that could be used in the setup of an international project, "Hippocrates" (H-project), named after the author of the endocrine theory of temperaments. The H-project can aim to summarize the findings in functional neurochemistry of consistent behavioural patterns (CBPs) in health (such as temperament traits) and psychopathology (symptoms of psychiatric disorders); to have systematically structured neurochemical investigations; to have an analysis of CBPs that include all ranges of behavioural histories and to have these modules complemented by regional contrasts related to climate, diets and other bio-environmental factors. The review highlights the benefits of constructivism and illustrates the contrast between constructivism and current approaches in terms of analytic and methodological aspects. (1) "Where" the neurochemical biomarkers should be measured: the review expands the range of needed measurements to out-of-brain systems, including environmental factors, and explores the concept of Specialized Extended Phenotype. (2) "What" should be measured but is missing: the review points to the need for measurement of the "Throw & Catch" neurochemical relays; behavioural and neuronal events contributing to the consistency of the CBPs but not documented in measurements. (3) Structuring the H-project's setup: the paper briefly describes a proposed earlier neurochemical framework, Functional Ensemble of Temperament that that accommodates the neurochemical continuum between temperament and symptoms of psychiatric disorders. This framework is in line with documented "Throw & Catch" neurochemical relays and can also be used to organize data about the personal and professional history of an individual.

Abstract
Background: Depression is the third leading cause of worldwide disease burden among youth, and nutrition- and diet-related behaviors have been considered as an effective strategy for reducing the risk of depressive symptoms. This systematic review aims to examine associations between dietary intake and diet quality with depressive symptoms among youth. Methods: In this systematic review, a search of scientific articles published between 2000 and 2021 was performed in four databases (CINAHL, Embase, PsycInfo, and PubMed) according to the PRISMA checklist. After applying inclusion and exclusion criteria, observational studies that focused on associations between micronutrient, macronutrient, food group intake, and diet quality and depressive symptoms among youth, ages 3 to 18, were selected for review. Results: Thirty-two articles met the review criteria. Dietary intake of magnesium, vitamin B12, fiber, fruits, vegetables, and fish were consistently inversely related to depressive symptoms. However, the evidence of associations between intake of vitamins B6, C, D, and E, iron, copper, zinc, omega-3 fatty acids, carbohydrate, and dietary fat and depressive symptoms was mixed. Dietary effects on decreased depressive symptoms were more pronounced in children than adolescents. Additionally, most studies failed to adjust for potential confounding variables. Conclusion: This review provides preliminary and comprehensive evidence for a relationship between dietary intake, diet quality, and depressive symptoms in youth. Although the results are heterogeneous and more research is needed, our findings indicate the importance of nutrition interventions for youth for decreasing depressive symptoms or for preventing further symptom exacerbation.

Abstract
Using the Unpredictable Chronic Sleep Deprivation (UCSD) paradigm we developed, the combined effects of chronic sleep deprivation and high caffeine intake on prefrontal cortical synaptophysin expression, neurochemical profiles, and behavioural outcomes in Long-Evans rats were evaluated. The combination of chronic sleep deprivation and high-dose caffeine treatment produced varying degrees of behavioural impairments, depletion of antioxidants, serotonin, and an upregulation of acetylcholinesterase (AChE) activity in the prefrontal cortex. An immunohistochemical assessment revealed a reduction in synaptophysin protein expression in the prefrontal cortex following exposure to high-dose caffeine and chronic sleep deprivation. Overall, our findings support the advocacy for adequate sleep for optimal mental performance as a high intake of caffeine to attenuate the effects of sleep deprivation that may alter the neurochemical profile and synaptic plasticity in the prefrontal cortex, significantly increasing the risk of neuropsychiatric/degenerative disorders.

Abstract
INTRODUCTION Alcohol, tobacco and coffee are commonly used substances and use in adolescence has previously been linked to mood disorders. However, few large prospective studies have investigated adolescent use in relation to mental health outcomes in adulthood. The main aim of this study was to examine the prospective associations between alcohol use, cigarette smoking and coffee consumption at age 16 and subsequent mood disorders up to 33 years of age. METHODS Data from The Northern Finland Birth Cohort 1986 Study were used and a total of 7660 participants (49.9% male) were included. Associations between alcohol use, cigarette smoking and coffee consumption at age 16 and later diagnoses of major depression and bipolar disorder were examined using multinomial logistic regression analyses. RESULTS Mean number of cigarettes/day (OR, 1.23 [95% CI 1.01-1.50]) and mean volume of alcohol consumption (OR, 1.22 [95% CI 1.01-1.47]), but not frequency of excessive drinking, in adolescence were associated with increased risk for subsequent bipolar disorder after adjustment for sex, parental psychiatric disorders, family structure, illicit substance use, and emotional and behavioral problems at age 16. An association between cigarette smoking and major depression attenuated to statistically non-significant when adjusted for emotional and behavioral problems. No associations were observed between adolescent coffee consumption and subsequent mood disorders. CONCLUSIONS This is the first study to report an association of adolescent cigarette smoking and subsequent bipolar disorder diagnosis providing grounds for further research and pointing to a place for preventive measures among adolescents.

Abstract
Fermentation is one of the world’s oldest techniques for food preservation, nutrient enhancement, and alcohol manufacturing. During fermentation, carbohydrates such as glucose and starch are converted into other molecules, such as alcohol and acid, anaerobically through enzymatic action while generating energy for the microorganism or cells involved. Black tea is among the most popular fermented beverages; it is made from the dried tea leaves of the evergreen shrub plant known as Camellia sinensis. The adequate consumption of black tea is beneficial to health as it contains high levels of flavanols, also known as catechins, which act as effective antioxidants and are responsible for protecting the body against the development of illnesses, such as inflammation, diabetes, hypertension, cancer, and obesity. The prevalence of obesity is a severe public health concern associated with the incidence of various serious diseases and is now increasing, including in Malaysia. Advances in ‘omic’ research have allowed researchers to identify the pivotal role of the gut microbiota in the development of obesity. This review explores fermented black tea and its correlation with the regulation of the gut microbiota and obesity.

Abstract
Background Caffeine is widely consumed among students due to its cognitive and physical enhancing effects. However, little is known about the consumption pattern of different caffeinated products among university students in the United Arab Emirates (UAE). Aim To investigate the frequency of caffeine consumption among the young population of students, assess types of caffeinated products consumed, and document adverse effects and withdrawal symptoms experienced by university students. Methods A cross-sectional study was conducted in the UAE from December 2019 to March 2020. A random sample of 500 university students from different universities in the UAE were approached and asked to complete a self-administered online-based questionnaire. Data were analyzed using the Statistical Package for Social Science (SPSS) version 26. Results Of (n = 500) surveyed students, (n = 467) completed the survey 93.4%. The average level of caffeine consumption was significantly higher in females compared to male students (p < 0.005). Coffee was the highest favored source of caffeine (67.7%) followed by tea (47.3%). The average daily intake of caffeine was found to be 264 mg/day. Surprisingly, almost a third of students reported a high level of daily consumption (>400 mg/day) and more than half of them consumed less than 199 mg/day. Large proportions of students 91.1% have their caffeinated beverage after or while eating meals and 42.8% considered that this habit helped in avoiding acid reflux. Interestingly, around one third of participants have poor knowledge of caffeine-containing medical products, which seemed to affect the level of consumption in the student population (p < 0.05). The highest reported reason for caffeine intake was for studying purposes (59.4%). Conclusion Caffeine consumption is highly prevalent among university students in the UAE. Yet, there is insufficiency in the current knowledge of safe caffeine consumption patterns reflecting the importance of health awareness programs and nutritional lectures to decrease the long-term health issues and unintentional overdose of caffeine.

Abstract
As a nonspecific antagonist of the adenosine A2A receptor (A2AR), caffeine enhances learning and improves memory impairment. Simultaneously, the consumption of caffeine correlates with a feeling of anxiety. The hippocampus is functionally differentiated along its dorsal/ventral axis and plays a crucial role both in memory and anxiety. Whether caffeine exerts its regulation by inhibiting A2ARs in different subregions of the hippocampus is still unknown. In the present study, we found that after chronic intake of drinking water containing caffeine (1 g/L, 3 weeks), mice exhibited aggravated anxiety-like behavior and enhanced memory function. Tissue-specific, functional disruption of dorsal hippocampal A2ARs by the CRE-LoxP system prevented the memory-enhancing effect of caffeine, while selective disruption of ventral hippocampal A2ARs blocked the impact of caffeine on anxiety. These results, together with the enhanced memory of dorsal hippocampus A2AR knockout mice and greater anxiety-like behavior of ventral hippocampus A2AR knockout mice without caffeine, indicates a dissociation between the roles of ventral and dorsal hippocampal A2A receptors in caffeine’s effects on anxiety-like and memory-related behavioral measures, respectively. Furthermore, optogenetic activation of dorsal or ventral hippocampal A2ARs reversed the behavioral alterations caused by drinking caffeine, leading to impaired memory or decreased anxiety-like behaviors, respectively. Taken together, our findings suggest that the memory- and anxiety-enhancing effects of caffeine are related to the differential effects of inhibiting A2ARs in the dorsal and ventral hippocampus, respectively.

Abstract
Attention-deficit/hyperactivity disorder (ADHD) and anxiety disorders (AD) frequently co-occur, increasing morbidity and challenging treatment. Caffeine is a central nervous system stimulant and acts in the brain through adenosine receptors, influencing attention, alertness, and anxiety. In the present study, we performed a gene-set analysis to verify if genes related to caffeine response are associated with anxiety disorders in 240 children and 406 adults with ADHD. We demonstrated an association between the gene-set with AD in children (P = 0.0054) and with the number of anxiety disorders in adults (P = 0.0197). In order to test if this effect is a result of anxiety in general or is related to AD comorbid with ADHD, we evaluated the association between caffeine gene-set with AD in an adult control sample. The gene-set was neither associated with the AD presence (P = 0.3008) nor with the number of AD (P = 0.5594) in this control sample. We also test this gene set with ADHD (n = 55,374) and AD (n = 18,186) GWAS summary statistics, and we did not observe significant results with ADHD (P = 0.5587) or AD (P = 0.3930). These findings suggest the caffeine-related genes play a role in the etiology of an anxiety disorder phenotype present in children and adults with ADHD.

Abstract
Coffee is the most widely consumed source of caffeine worldwide, partly due to the psychoactive effects of this methylxanthine. Interestingly, the effects of its chronic consumption on the brain's intrinsic functional networks are still largely unknown. This study provides the first extended characterization of the effects of chronic coffee consumption on human brain networks. Subjects were recruited and divided into two groups: habitual coffee drinkers (CD) and non-coffee drinkers (NCD). Resting-state functional magnetic resonance imaging (fMRI) was acquired in these volunteers who were also assessed regarding stress, anxiety, and depression scores. In the neuroimaging evaluation, the CD group showed decreased functional connectivity in the somatosensory and limbic networks during resting state as assessed with independent component analysis. The CD group also showed decreased functional connectivity in a network comprising subcortical and posterior brain regions associated with somatosensory, motor, and emotional processing as assessed with network-based statistics; moreover, CD displayed longer lifetime of a functional network involving subcortical regions, the visual network and the cerebellum. Importantly, all these differences were dependent on the frequency of caffeine consumption, and were reproduced after NCD drank coffee. CD showed higher stress levels than NCD, and although no other group effects were observed in this psychological assessment, increased frequency of caffeine consumption was also associated with increased anxiety in males. In conclusion, higher consumption of coffee and caffeinated products has an impact in brain functional connectivity at rest with implications in emotionality, alertness, and readiness to action.

Abstract
Nowadays, caffeine is one of the most commonly consumed substances, which presents in many plants and products. It has both positive and negative effects on the human body, and its activity concerns a variety of systems including the central nervous system, immune system, digestive system, respiratory system, urinary tract, etc. These effects are dependent on quantity, the type of product in which caffeine is contained, and also on the individual differences among people (sex, age, diet etc.). The main aim of this review was to collect, present, and analyze the available information including the latest discoveries on the impact of caffeine on human health and the functioning of human body systems, taking into account the role of caffeine in individual disease entities. We present both the positive and negative sides of caffeine consumption and the healing properties of this purine alkaloid in diseases such as asthma, Parkinson's disease, and others, not forgetting about the negative effects of excess caffeine (e.g., in people with hypertension, children, adolescents, and the elderly). In summary, we can conclude, however, that caffeine has a multi-directional influence on various organs of the human body, and because of its anti-oxidative properties, it was, and still is, an interesting topic for research studies including those aimed at developing new therapeutic strategies.

Abstract
The aim of the current review was to analyze primary studies about energy drink consumption patterns in adolescents and their relationship with mental health. PubMed, PLOS ONE, PsycINFO, and ScienceDirect databases were searched to identify articles related to adverse effects of energy drinks in adolescents and young adults aged 11 to 18 years. Psychological and behavioral measures were based on validated screening tools used in various contexts, and bias was detected in energy drink consumption patterns. In regard to sex, boys consumed more energy drinks than girls, and a strong, positive association was reported between consumption and probability of risky behaviors; tendency for anxiety, depression, and impulsivity; poor academic performance; and sleep disturbances. A progressive increase in consumption was also noted of 25% to 75% within 5 years. Findings suggest that standardized consumption pattern assessment be included in evaluations of mental health to determine potential causal relationships.

Abstract
OBJECTIVE This study was conducted to study the anxiety scores among undergraduate university students in Jordan during COVID-19 pandemic and to assess the relationship between quarantine and shifting to distance learning resulted from the governmental strict isolation measures and severity of anxiety among students. METHODS A cross-sectional design was conducted to meet the study objectives. A convenience sample of 736 undergraduate university students in Jordan was recruited, and anxiety was assessed using the Hamilton Anxiety Scale. RESULTS The results indicated that anxiety score was 22.76 and 40.6% of the participant experienced moderate to severe anxiety, whereas 23.5% experienced mild to moderate anxiety and 35.9% experienced mild anxiety. Factors like suffering from chronic illnesses, having chronic medications, grade point average, shifting to distance learning, quarantine during the pandemic, study duties, the newly developed evaluation methods and the experience of students towards the use of anti-anxiety drugs and herbs had significantly increased the anxiety scores. CONCLUSION Our findings indicate that quarantine and shifting to distance learning during COVID-19 pandemic have negatively affected the anxiety scores of the university students which should be taken in consideration by the policymakers in Jordan in order to support this vulnerable group.

Abstract
Abstract
Background
University students use caffeine to cope with stress in spite of its adverse effects. The purpose of this study is to explore caffeine consumption among university students in Saudi Arabia, as well as its correlation with stress and caffeine intoxication. This cross-sectional study examined a convenience sample of 547 students at Princess Nourah Bint Abdulrahman University (PNU). A self-administrated questionnaire was used to assess caffeine consumption in milligrams per day, stress was assessed by the perceived stress scale (PSS), and caffeine intoxication was assessed using the DSM-5 criteria.
Results
The mean total caffeine consumption was 424.69 ± 385.31 mg/day. High levels of caffeine consumption were found among students of non-health colleges and students who were undiagnosed with psychiatric disorders (p values <0.040 and 0.027, respectively). A significant positive correlation was found between caffeine consumption and perceived stress (p<0.045). Only 13.26% of all participants fulfilled the DSM-5 criteria for caffeine use disorder. The majority of participants showed moderate and high stress levels (69.9% and 18.7%).
Conclusion
This study revealed high caffeine consumption and perceived stress levels among female undergraduate students with a significant positive association between them. The results emphasize the importance of educational campaigns about caffeine consumption and intoxication. They also encourage the development of stress management programs. Longitudinal studies need to be designed for evidence-based intervention.

Abstract
Diet, dietary practices and exercise are modifiable risk factors for individuals living with mental distress. However, these relationships are intricate and multilayered in such a way that individual factors may influence mental health differently when combined within a pattern. Additionally, two important factors that need to be considered are gender and level of brain maturity. Therefore, it is essential to assess these modifiable risk factors based on gender and age group. The purpose of the study was to explore the combined and individual relationships between food groups, dietary practices and exercise to appreciate their association with mental distress in mature men and women. Adults 30 years and older were invited to complete the food–mood questionnaire. The anonymous questionnaire link was circulated on several social media platforms. A multi-analyses approach was used. A combination of data mining techniques, namely, a mediation regression analysis, the K-means clustering and principal component analysis as well as Spearman’s rank–order correlation were used to explore these research questions. The results suggest that women’s mental health has a higher association with dietary factors than men. Mental distress and exercise frequency were associated with different dietary and lifestyle patterns, which support the concept of customizing diet and lifestyle factors to improve mental wellbeing.

Abstract
Purpose
The purpose of this study is to analyse various risks associated with third-party logistics (3PL) in the coffee supply chain and to present a framework that computes the influence of these risks on the critical success factors of the coffee supply chain.
Design/methodology/approach
The risks have been identified through a comprehensive literature review and validation by industry experts. The paper utilises an interpretive structural modelling (ISM) methodology for developing a hierarchical relationship among the CSFs. Furthermore, fuzzy MICMAC analysis is carried out to categorise these CSFs based on their driving power and dependence value. The fuzzy technique for order preferences by the similarity of an ideal solution (fuzzy-TOPSIS) approach has been applied to prioritise the risks associated with 3PL based on their ability to influence the CSFs of the coffee SC. Furthermore, we performed a sensitivity analysis to analyse the stability of the results obtained in this study.
Findings
This study illustrates ten risks associated with 3PL and five CSFs in the coffee supply chain. The analysis revealed that coffee enterprises need to develop a balanced pricing strategy to ensure a sustainable competitive advantage, whereas the lack of direct customer communication is the most dominant 3PL risk affecting the CSFs.
Practical implications
This research provides coffee enterprises with a generalised framework with set parameters that can be used to attain a successful coffee supply chain in any developing nation.
Originality/value
The study contributes to the literature by being the first kind of study, which has used fuzzy ISM-MICMAC to analyse the CSFs of the coffee supply chain and fuzzy-TOPSIS for analysing the impact of various risks associated with the 3PL in the coffee supply chain. Thus, this work can be considered a benchmark for future research and advancement in the coffee business field.

Abstract
Background The effect of caffeine on the human body, both short-term and long-term, has been studied in great depth, particularly its association with psychiatric disorders. This study aims to investigate whether there is a correlation between caffeine intake and anxiety and depression among college students. Methodology A survey was administered to college students at Florida State University. Data regarding participant characteristics and caffeine intake were collected. Generalized Anxiety Disorder-7 and Patient Health Questionnaire-9 scores were used to assess symptoms of anxiety and depression, respectively. Results A total of 114 participants were included in the survey, consisting mainly of women (94 [82.5%]) and junior-level students (37 [32.5%]). The main source of caffeine was coffee (64.0%), and the main reasons for caffeine intake were pleasure (43.9%) and to study outside of class (29.8%); however, no association was found between sex or grade point average and number of cups of caffeine consumed. Upper levels of education (super senior or fifth-year students), depressive symptoms (poor appetite, overeating, sleep disorders, depressed mood), and anxiety were statistically associated with greater caffeine intake (P < 0.05). Conclusions As caffeine is commonly consumed and our study showed that its intake was associated with depressive symptoms and higher levels of anxiety in college students, further studies are needed to determine a possible causality, so that measures may be taken to educate these students about alternative methods for increasing energy and alertness.

Abstract
Background: Adolescent caffeine consumption has been linked to aggressive behaviors, although no longitudinal tests have been reported to date. The purpose of this study was to test the longitudinal relations between daily adolescent caffeine consumption and aggressive behaviors. Methods: Two waves of survey data collected 12 months apart in the spring of 2018 and 2019, from the 2004 birth cohort in the Icelandic LIFECOURSE study, were analyzed using structural equation modeling (N = 2,278). Both direct and mediated models were employed. Results: Caffeine use at time 1 (T1) was associated with aggressive behavior at time 2 (T2) (β = .12, p < .001) independent of aggressive behavior at T1. A considerable added relation was observed between caffeine at T1 and aggressive behavior at T2 via indirect (i.e., mediated) effects of aggressive behavior at T1 (standardized β = .20, p < .001). Over 64% of the standardized total effect (β = .31) observed between caffeine at T1 and aggressive behavior at T2 was due to mediation. Conclusion: Adolescent caffeine consumption forecasts aggressive behaviors. Caffeine use at T1 increased the likelihood of self-reported aggressive behaviors 12 months later irrespective of level of reported aggressive behavior at T1 while controlling for common confounders.

Abstract
Background: Caffeine use and abuse is a concern among treatment seekers for psychological problems. This aspect has not been documented an Indian context as well as its relevance in primary care setting. The aim of the present study was to explore and compare the caffeine intake and prevalence in Indian psychiatric patients and healthy subjects. Materials and Methods: Caffeine analysis in urine samples was carried out using a gold technique, gas chromatograph and mass selective detectors. This analytical technique is highly sensitive for identification of unambiguous compound. Two hundred and forty-three subjects having psychiatric disorders, along with forty-two healthy subjects were included in the study. They were assessed by using structured interview for caffeine use and screened for substance dependence as well. Results: One hundred twenty-eight subjects had history of substance use along with other comorbid psychiatric problems The mean of caffeine values was 1459 ± 1140 ng/mL, Whereas 42 subjects in control group (male 26, female 16) in the age group of 21–60 years had the mean caffeine levels of 1023 ± 788.8 ng/mL. The Caffeine use was significantly higher (P ≥ 0.84) in the subjects with psychiatric problems in comparison to the healthy subjects. Conclusions: It implies the need to enable and sensitize the primary care physicians in screening and educating treatment seekers with psychiatric morbidities for the management of caffeine use.

Xie L, Tang Q, Yao D, Gu Q, Zheng H, Wang X, Yu Z, Shen X. Effect of Decaffeinated Green Tea Polyphenols on Body Fat and Precocious Puberty in Obese Girls: A Randomized Controlled Trial. Front Endocrinol (Lausanne) 2021; 12:736724. [PMID: 34712203 PMCID: PMC8546255 DOI: 10.3389/fendo.2021.736724] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2021] [Accepted: 09/20/2021] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Obesity has been reported to be an important contributing factor for precocious puberty, especially in girls. The effect of green tea polyphenols on weight reduction in adult population has been shown, but few related studies have been conducted in children. This study was performed to examine the effectiveness and safety of decaffeinated green tea polyphenols (DGTP) on ameliorating obesity and early sexual development in girls with obesity. DESIGN This is a double-blinded randomized controlled trial. Girls with obesity aged 6-10 years old were randomly assigned to receive 400 mg/day DGTP or isodose placebo orally for 12 weeks. During this period, all participants received the same instruction on diet and exercise from trained dietitians. Anthropometric measurements, secondary sexual characteristics, B-scan ultrasonography of uterus, ovaries and breast tissues, and related biochemical parameters were examined and assessed pre- and post-treatment. RESULTS Between August 2018 and January 2020, 62 girls with obesity (DGTP group n = 31, control group n = 31) completed the intervention and were included in analysis. After the intervention, body mass index, waist circumference, and waist-to-hip ratio significantly decreased in both groups, but the percentage of body fat (PBF), serum uric acid (UA), and the volumes of ovaries decreased significantly only within the DGTP group. After controlling confounders, DGTP showed a significantly decreased effect on the change of PBF (β = 2.932, 95% CI: 0.214 to 5.650), serum UA (β = 52.601, 95% CI: 2.520 to 102.681), and ovarian volumes (right: β = 1.881, 95% CI: 0.062 to 3.699, left: β = 0.971, 95% CI: 0.019 to 1.923) in girls with obesity. No side effect was reported in both groups during the whole period. CONCLUSION DGTP have shown beneficial effects of ameliorated obesity and postponed early sexual development in girls with obesity without any adverse effects.

Effect of Caffeine Consumption on the Risk for Neurological and Psychiatric Disorders: Sex Differences in Human. Nutrients 2020; 12:nu12103080. [PMID: 33050315 PMCID: PMC7601837 DOI: 10.3390/nu12103080] [Citation(s) in RCA: 54] [Impact Index Per Article: 13.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2020] [Revised: 10/02/2020] [Accepted: 10/04/2020] [Indexed: 02/06/2023] Open
Abstract
Caffeine occurs naturally in various foods, such as coffee, tea, and cocoa, and it has been used safely as a mild stimulant for a long time. However, excessive caffeine consumption (1~1.5 g/day) can cause caffeine poisoning (caffeinism), which includes symptoms such as anxiety, agitation, insomnia, and gastrointestinal disorders. Recently, there has been increasing interest in the effect of caffeine consumption as a protective factor or risk factor for neurological and psychiatric disorders. Currently, the importance of personalized medicine is being emphasized, and research on sex/gender differences needs to be conducted. Our review focuses on the effect of caffeine consumption on several neurological and psychiatric disorders with respect to sex differences to provide a better understanding of caffeine use as a risk or protective factor for those disorders. The findings may help establish new strategies for developing sex-specific caffeine therapies.

Abstract
There is growing interest in lifestyle and behavioral strategies not only in prevention but also in the management of psychiatric morbidity. Available literature in this direction was accessed, and the role of various lifestyle and behavioral factors was explored. There is strong evidence of the role of good sleep, nutritious diet, exercise, social connectedness, enhanced self-esteem, sense of purpose in life, resilience, mindfulness, and environmental mastery in the promotion of mental well-being and prevention and management of psychiatric disorders. There is a significant scope of lifestyle and behavioral intervention in ensuring positive mental health spanning from preventive to therapeutic dimension.

Abstract
The Dietary Guidelines for Americans (DGA) provide nutrition advice for Americans >2 y of age. The 2020-2025 DGA proposes a life stage approach, focusing on birth through older adulthood. Limited recommendations for beverages exist except for milk, 100% fruit juice, and alcohol. The goal of this article is to provide a better understanding of the role of beverages in the diet using current scientific evidence. A Medline search of observational studies, randomized controlled trials, and meta-analyses was undertaken using key beverage words. We highlight the role beverages can play as a part of the DGA and considered beverages not traditionally included, such as those that are phytonutrient dense. Our primary consideration for beverage consumption targeted healthy Americans aged ≥2 y. However, with the proposed expansion to the life span for the 2020-2025 DGA, we also reviewed evidence for infants and toddlers from birth to 24 mo. Examples are provided on how minor changes in beverage choices aid in meeting recommended intakes of certain nutrients. Guidance on beverage consumption may aid in development of better consumer products to meet broader dietary advice. For example, beverage products that are nutrient/phytonutrient dense and lower in sugar could be developed as alternatives to 100% juice to help meet the fruit and vegetable guidelines. Although beverages are not meant to replace foods, e.g., it is difficult to meet the requirements for vitamin E, dietary fiber, or essential fatty acids through beverages alone, beverages are important sources of nutrients and phytonutrients, phenolic acids and flavonoids in particular. When considering the micronutrients from diet alone, mean intakes of calcium (in women), potassium, and vitamins A, C, and D are below recommendations and sodium intakes are well above. Careful beverage choices could close these gaps and be considered a part of a healthy dietary pattern.

Lee CH, George O, Kimbrough A. Chronic voluntary caffeine intake in male Wistar rats reveals individual differences in addiction-like behavior. Pharmacol Biochem Behav 2020; 191:172880.

Abstract
Caffeine is the most widely consumed psychoactive substance in the world. However, there is controversy about whether becoming addicted to caffeine is possible and a lack of well-established animal models to examine caffeine consumption. The present study sought to establish a model of caffeine consumption in Wistar rats, identify different rat populations based on caffeine preference, and determine whether extended voluntary caffeine consumption produces compulsive-like caffeine intake and withdrawal symptoms. Male Wistar rats were used throughout the experiment. The optimal concentration of caffeine to maximize caffeine consumption and caffeine preference was determined. Rats were then given continuous access to caffeine, followed by intermittent access. Rats were tested for signs of withdrawal-like behavior by measuring mechanical nociception and irritability-like behavior. Rats were further examined for compulsive-like caffeine consumption using quinine adulteration. Dose-response testing indicated an optimal caffeine concentration of 0.3 mg/mL. During intermittent access to caffeine, the rats did not escalate their caffeine intake and instead exhibited a decrease in intake over sessions. Three groups of rats were identified based on caffeine preference (high, medium, and low) across continuous and intermittent access. These three groups of rats matched low (1 cup), medium (2 cups), and high (4 cups) levels of daily coffee consumption in humans. Caffeine-consuming rats did not exhibit differences in mechanical nociception or irritability-like behavior compared with controls. In high caffeine-preferring rats but not in medium or low caffeine-preferring rats, compulsive-like caffeine consumption was observed. The present study established a rodent model of caffeine consumption that resulted in large individual differences in caffeine intake, similar to humans. Compulsive-like caffeine consumption in high caffeine-preferring rats and differences in caffeine preference between groups suggest that caffeine may result in compulsive-like intake in a subpopulation of subjects. Further testing is necessary to determine the factors that contribute to differences in caffeine preference and compulsive-like intake.

Community pharmacists' recommendations for natural products for stress in Melbourne, Australia: a simulated patient study. Pharm Pract (Granada) 2020; 18:1660. [PMID: 32256893 PMCID: PMC7092712 DOI: 10.18549/pharmpract.2020.1.1660] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2019] [Accepted: 02/16/2020] [Indexed: 12/20/2022] Open
Abstract
Background: Community pharmacists are often the first health professional approached to provide treatment for health issues, including the important mental health challenge, stress. Over-the-counter products for stress almost always are complementary and alternative medicines (CAM) and in Australia no protocol exists for their recommendation and sale in community pharmacies. Objective: To assess the quality and relevance of community pharmacists’ information gathering (questioning), counselling and product selection when interacting with customers requesting a CAM product for stress and consequently determine whether Australian pharmacy practice indicates the need for guidelines similar to those provided for ‘pharmacy only’ (S2) and ‘pharmacist only’ (S3) medicines. Methods: A covert simulated patient was used to investigate the response of pharmacists to a request for a natural product for stress. The SPs documented the details of the pharmacist-simulated patient interaction immediately on leaving the pharmacy and then re-entered the pharmacy to debrief the pharmacist. The quality of the interaction was scored as a Total CARE (check, assess, respond, explain) Score, based on anticipated questions and counselling advice. The appropriateness of the product was scored as a Product Efficacy Score, based on evidence-based literature. Results: Data from 100 pharmacies was provided. Information gathering illustrated by the questioning components Check and Assess (C and A) of the total CARE score by pharmacists was poor. The number of questions asked ranged from zero (13 pharmacists) to 7 (four pharmacists), the average being 3.1 (SD 1.9). Provision of advice was generally better (a description of the suggested product was offered by 87 pharmacists) but was lacking in other areas (duration of use and side effects were explained by only 41 and 16 pharmacists respectively). The most common product suggested was B-group vitamins (57 pharmacists) followed by a proprietary flower essence product (19 pharmacists). A two-step cluster analysis revealed two sub-groups of pharmacists: one cluster (74 pharmacists) with a high Total CARE score provided an appropriate product. The other cluster (20 pharmacists) had a low total CARE score and provided an inappropriate product. Conclusions: The pharmacy visits revealed major shortcomings in questioning, counselling and product recommendation. There is a need to develop guidelines for pharmacists to make evidence-based decisions in recommending complementary and alternative medicine.

Ann Gen Psychiatry 2020; 19:29. [PMID: 32391067 PMCID: PMC7196228 DOI: 10.1186/s12991-020-00274-7] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2018] [Accepted: 03/26/2020] [Indexed: 11/25/2022] Open
Abstract
INTRODUCTION Medical education is proven to be associated with a high degree of psychological stress. Different coping strategies used by students have been investigated on their efficacy. So far, studies on medical students have been limited to a single population. AIM OF THE STUDY Our study aimed to identify differences in the prevalence of depressive symptoms, anxiety, stress levels, and defense mechanisms among two groups of medical students, the Polish and English-speaking divisions. MATERIALS AND METHODS The study included two groups of first-year medical students, the Polish and English-speaking divisions, comprising 305 participants (n = 204 Polish, n = 101 English, men = 127, women = 176). It was divided into two periods: the students received author questionnaires during an exam-free academic period and then completed the same questionnaires during an exam session. The survey contained questions pertaining to demographics and studying habits among participants and included the Defense Style Questionnaire and Depression Anxiety Stress Scales. Data were analyzed using STATISTICA version 12.0, and p ≤ 0.05 was considered significant. RESULTS Polish medical students presented with significantly increased overall stress levels (p = 0.007858) and depressive symptoms (p = 0.030420) compared to the English division students. Polish students also presented with more symptoms of stress, depression, and anxiety during the exam period compared to the exam-free period (p = 0.000625), which did not apply to the English-speaking students. The English division students reached higher scores in the mature defense mechanisms section than the Polish students (p = 0.000001). The use of mature defense mechanisms correlated negatively with the intensity of stress, anxiety, and depressive symptoms in both groups, while immature defense mechanisms promoted higher values of those variables (p = 0.000001). CONCLUSIONS Our study showed significant and multidirectional differences between medical students of the Polish and English divisions attending the same university. Such results could suggest that strategies aimed at reducing depressive symptoms among medical students ought to be adapted towards the needs of a specific population.
