Slide1: Gender Differences in Caffeine Consumption LITERATURE REVIEW DISCUSSION RESULTS Chart 1. Label in 24pt Arial. Table 1. Initial Survey Results Table 2. Survery Results Including Means and Standard Deviation METHODS AND MATERIALS REFERENCES CONTACT Of 26 respondents 23% were male and 76% female It was broken down into four specific attributes Preference Influence on Alertness Brands influence on choice Differing of Price Mood was one of the biggest factors prevalent when it came to choosing coffee or tea The research was inconclusive when it came to supporting or going against our hypothesis Current study supports previous studies that coffee is the preferred choice between coffee and tea (Mahoney, 2018) Current study also found that caffeine is mainly used for alertness and needing to feel awake, which supports previous research (Agoston et. al, 2017) Current study found that women preferred coffee over tea which is contrary to previous research which showed women drank less coffee than men with taste being a factor ( Ghali (2016) and Demura et.al (2013) Limitations of current study are… Size of sample Due to size of sample, lack of generalizability Respondents were female by majority which may represent a gender bias in the data Unable to directly link gender to responses Future research should… Control for different additives into novelty coffee and tea drinks Include other genders now included Update studies to identify new patterns of caffeine use with new social norms Research consisted of 26 participants, both men and women, ranging from non graduate to graduate students including family. Survey was conducted through a volunteered basis and was distributed via social media (facebook, twitter) Survey consisted of 10 questions, 8 qualitative questions and 2 quantitative questions. Qualitative questions were answered through a series of “strongly agree to strongly Disagree” while qualitative question were answered to participants discretion. Samples mainly included college-aged students (ages 18-25). Literature showed that there is a gender difference between caffeine consumption. Mostly that men consume more coffee than women. 50% of men drink coffee versus 32% of women (D’Souza 2018). Most studies were conducted through surveys, but there were also twin studies conducted to look for a genetic component to caffeine consumption (Laitala et.al 2008) Caffeine takes less time to activate in males (Adan et.al 2008) Reasons for consumption included stress and enhancing mood and performance (Mahoney 2018). Tifferet, Shani, & Cohen (2013) sought to explore the differences in caffeine use between males and females, in regards to the brands of caffeine products and the need to express their status in social circles. The study found that men are more likely than women to purchase higher brand caffeine products than women. In the study by Roth (2015), they tested the way different caffeine, mainly coffee, intake has an effect on an individual's mood and thinking and the duration of the effects. They found that individuals would peak in mood 2.5 hours after consuming coffee and then decrease at the 5 hour mark. V.L. Errisuiriz et. al writes, “findings indicate greater stress is associated with poor dietary choices among college freshmen” (V.L. Errizuiriz et. al., p. 211, 2013). This idea may explain why there is an increase in caffeine consumption in college-aged individuals. Adan et al.
