Abstract:

The purpose of this study was to determine the prevalence of caffeine and catechin consumption among university students, as well as their effect on depression and stress. We conducted a study in which we administered a questionnaire to 950 undergraduate students studying at Istanbul Aydn University between February and March 2020. The questionnaire included descriptive questions, caffeine and catechin consumption amounts, the Beck Depression Inventory, and a "perceived stress scale". We evaluated general characteristics, the Beck Depression Inventory, and the "perceived stress scale, and used logistic regression analysis. This study included 950 students (54.6 percent of whom were female). BMI classification of 950 students: 3.0% of men are obese, 32.5 % are slightly obese, 62.6 % are normal, 1.9 % are thin; 2.3 % of women are obese, 15.6 % are slightly obese, 71.7 % are normal, and 10.4 % are weak. The average daily caffeine consumption of the majority of students (465.01 156.48 males, 488.70 142.05 females) and catechin consumption (831.11 327.55 males, 841.58 348.07 females) is quite high. The average caffeine consumption of male and female students indicates that the majority of them consume a high dose of caffeine. There was a statistically significant difference (p<0.05) between the caffeine consumption rates of female and male students, and this difference is due to female students' higher caffeine consumption than male students. Caffeine consumption levels are not significantly different according to the students' age distribution (p > 0.05). According to their average catechin consumption, the majority of female and male students consume high levels of catechin. There is no significant difference in catechin consumption levels between students' genders or ages (p > 0.05). Depression levels among students differ significantly by gender (p< 0.05). Female students experience significantly higher rates of borderline, moderate, and severe depression than male students. Females perceived more stress than males. (0.05) There was a statistically significant difference (p 0.05) between the students' averages of total stress according to their ages. The level of depression rises in parallel with the level of caffeine intake (r =.194, p< .01). Stress levels rise in tandem with caffeine intake (r =.096, p< .01). When the level of perceived tension rises, so does the amount of caffeine consumed. (p < .01, r =.137). The degree of depression decreases as catechin intake increases (r = -.684, p< .01). When the amount of catechin consumed rises, so does the level of stress. (p < .01, r = -.164). The effects of caffeine on depression and stress, as well as the effects of catechin intake on depression and stress reduction.
