EFFECT OF CAFFEINE CONSUMPTION ON THE SLEEP QUALITY AMONG UNDERGRADUATE STUDENTS – CROSS SECTIONAL STUDY

Abstract

Caffeine is a common component in the modern diet, and its popularity is fueled by both its reputation as a stimulant and its flavor. The study conducted on undergraduate students to assess the patterns of sleep quality and investigate the degree to which poor sleep quality is connected with consumption of caffeine and other stimulants by any mean.

Methods. This cross-sectional study was carried out on 550 undergraduate students from various institutes in Karachi, Pakistan. After elimination, a total of 416 participants participated in the research with a slightly higher percentage of men (272) than women (144) in it. The average PSQI global score (SD) for the male participants was 6.32 (3.170), and 68.6% of them scored >5, indicating poor sleep. There are 84 undergraduate students who had not consumed caffeine by which 46 participants have poor sleep while 38 have good sleep quality (45.2%) It shows significant association between caffeine consumption on sleep quality (p-value  0.05) whereas for female students, there is no correlation (P-value > 0.05).

Conclusion. This study shows that the majority most undergraduate students have bad sleep quality, which has been correlated with consuming too many beverages high in caffeine. The results are in line with earlier studies that show college students who drink caffeinated beverages have a higher prevalence of sleep disruption.
