“…On the one hand, people who are used to drinking coffee in family contexts on a daily basisalso enjoy coffee in social situations. Especially among adolescents, drinking coffee is a way to spend time with friends and improve one's mood [24,25]. Moreover, compared to adults, adolescents are particularly oriented toward the upgraded social image they can project by consuming caffeinated beverages.…”

Over the last two years, many countries have enforced confinement to limit both the spread of COVID-19 and the demand for medical care. Confinement has resulted in a disruption of work routines, boredom, depression, and changes in eating habits, among them consumption of coffee and tea. Following six databases, we examined articles tracking consumption of these beverages. Out of 472 articles, including 23 beverage entries, 13 matched our criteria. While no clear trend in coffee consumption during the coronavirus pandemic emerged (7 of 13 studies indicated an increase, accounting for 53.8%), tea consumption clearly increased (70% versus 30%). Considering the global health emergency continuum, more research is needed to better understand the paths underlying food choices and the ways those changes may influence health outcomes, including those related to COVID-19 disease.

“…Indeed, adolescents report using caffeine to maintain focus and reduce fatigue during tasks that require sustained attention (e.g., classes at school) or to compensate for insufficient or inadequate sleep (Owens et al, 2014; Owens & Weiss, 2017). For example, adolescents report “getting through the day” as a primary motive for caffeine consumption (Bryant Ludden & Wolfson, 2010), and teenagers who consume more than 50 mg/day report using caffeine to stay awake and for its stimulant effects (Ludden, O’Brien, & Pasch, 2017; J. L. Temple, Dewey, & Briatico, 2010; see also Visram, Cheetham, Riby, Crossley, & Lake, 2016).…”

Despite the growing interest in caffeine use and its effects among adolescents, and a large literature on caffeine and attention among adults, there is a lack of experimental work examining the impact of caffeine on sustained attention among adolescents. We evaluated the acute effects of caffeine (vs. placebo) during a long (33-min) classic vigilance task among 31 adolescents (aged 12–17; 15 female; median caffeine use = 28 mg/day). We predicted a dose-dependent effect of caffeine, which would attenuate declines in target detection over time (i.e., a vigilance decrement). In each of 3 visits, participants completed an identical pairs continuous performance task beginning ∼25 min after consumption of noncaloric flavored water containing placebo, 1 mg/kg, or 3 mg/kg caffeine (order counterbalanced). Percent hits for low probability targets across 12 100-trial blocks was the primary outcome measure. As predicted, the linear decline in hits across trial blocks was attenuated by caffeine (Caffeine vs. Placebo × Block Linear, p = .01), with significant improvements in Blocks 9–12 (ps < .03). Compared to 1 mg/kg, 3 mg/kg caffeine resulted in earlier improvement in target detection (Drug Dose × Block Quadratic, p = .001). This study demonstrated that caffeine acutely and dose-dependently improves sustained attention among adolescents. These results were likely due to the attention-enhancing effect of caffeine, rather than withdrawal reversal, as our sample was characterized by light to moderate caffeine use. This study provides the foundation for further work on the impact of chronic caffeine consumption on cognitive function during adolescence.

“…It may be the case that caffeine impacts sleep when it is consumed in the evening, whereas there is little or no effect when it is consumed during the day. It is likely that most caffeine is consumed earlier during the day, given that a common reason for consuming caffeinated beverages is their stimulant effects (Ludden, O'Brien, & Pasch, ; Reich, Dietrich, Reid Finlayson, Fischer, & Martin, ). One small study ( n = 12) looked at the effects of a high dose of caffeine (400 mg, similar to the amount of caffeine in at least four cups of coffee) on sleep when administered 0, 3 or 6 hr before bedtime and did find disruptive effects on sleep at all time‐points (Drake, Roehrs, Shambroom, & Roth, ).…”

SummaryObservationally, higher caffeine consumption is associated with poorer sleep and insomnia. We investigated whether these associations are a result of shared genetic risk factors and/or (possibly bidirectional) causal effects. Summary‐level data were available from genome‐wide association studies on caffeine intake (n = 91 462), plasma caffeine and caffeine metabolic rate (n = 9876), sleep duration and chronotype (being a “morning” versus an “evening” person) (n = 128 266), and insomnia complaints (n = 113 006). First, genetic correlations were calculated, reflecting the extent to which genetic variants influencing caffeine consumption and those influencing sleep overlap. Next, causal effects were estimated with bidirectional, two‐sample Mendelian randomization. This approach utilizes the genetic variants most robustly associated with an exposure variable as an “instrument” to test causal effects. Estimates from individual variants were combined using inverse‐variance weighted meta‐analysis, weighted median regression and MR‐Egger regression. We found no clear evidence for a genetic correlation between caffeine intake and sleep duration (rg = 0.000, p = .998), chronotype (rg = 0.086, p = .192) or insomnia complaints (rg = −0.034, p = .700). For plasma caffeine and caffeine metabolic rate, genetic correlations could not be calculated because of the small sample size. Mendelian randomization did not support causal effects of caffeine intake on sleep, or vice versa. There was weak evidence that higher plasma caffeine levels causally decrease the odds of being a morning person. Although caffeine may acutely affect sleep when taken shortly before bedtime, our findings suggest that a sustained pattern of high caffeine consumption is more likely to be associated with poorer sleep through shared environmental factors. Future research should identify such environments, which could aid the development of interventions to improve sleep.
