Background: The number of prehypertension patients will always be higher than hypertension patients; this is supported by the prevalence of prehypertension being 48.40% according to JNC 7, and hypertension being 34.10% according to Basic Health Research in 2018. Coffee consumption and sleep quality were risk factors that are closely related to the lifestyle of students, this is also reinforced by the number of 24-hour coffee outlets that are open around Universitas Airlangga. Purpose: This aim of this study is to analyze the relationship between coffee consumption and sleep quality on the incidence of prehypertension in final year Universitas Airlangga students. Methods: This type of research is a quantitative study with a cross-sectional study design and uses the Chi-square test. The samples consisted of 146 people, which were taken using a simple random sampling method. Data collection was carried out through an online questionnaire. This study involved coffee consumption and sleep quality as independent variables and the incidence of prehypertension in final year Universitas Airlangga students as the dependent variable. Results: There is a correlation between coffee consumption (p=0.00) and sleep quality (p=0.01) with prehypertension in final year Universitas Airlangga students. Coffee consumption has a 2,47 times greater risk and sleep quality has a 2,09 times greater risk of prehypertension in final year Universitas Airlangga students. Conclusion: Poor coffee consumption and sleep quality are related with prehypertension in final year Universitas Airlangga students.

Diabetes mellitus (DM) is a chronic metabolic disorder and a major global problem. Coffee contains several bioactive compounds, such as caffeine, chlorogenic acid, trigonelline, cafestol, and kahweol, associated with a reduced risk of type 2 DM. This study aimed to assess the relationship between coffee consumption habits and blood glucose levels of farmers in Jenggawah Village, Jenggawah Subdistrict, Jember Regency. We used a cross-sectional study design. The sample of this study was 137 farmers who were taken by purposive sampling. Assessment of coffee consumption habits was conducted using a questionnaire. At the same time, data on random blood glucose levels were obtained from medical records of the Bakti Sosial Akbar dan Pengobatan Gratis Agromedis activities in Jenggawah Village in June 2022. Statistical analysis was performed using the Kruskall-Wallis test, and multivariate analysis using linear regression. The results showed that there was no statistically significant difference in random blood glucose levels between groups based on the variable type of coffee consumed (p=0.212), the level of coffee consumption (p=0.211), and the amount of sugar added to the coffee (p=0.086). However, the linear regression test results showed that the amount of added sugar in coffee had the greatest relationship with blood glucose levels compared to other independent variables (p=0.031). In conclusion, there was no relationship between coffee consumption habits and random blood glucose levels of farmers in Jenggawah Village. Further research is needed to confirm these findings.
