T, et al. – In a Japanese population, this study assessed the
relationship amongst coffee and greed tea intake and brain tumor risk,
study authors recommended that coffee consumption may decrease the
danger of brain tumor, including that of glioma.
Methods
- In the Japan Public Health Center-based Prospective Study (JPHC Study), the researchers assessed a cohort of 106,324 subjects (50,438 men and 55,886 women).
- From 1990 for Cohort I and 1993 for Cohort II until December 31, 2012, subjects were followed.
- During the study period, 157 (70 men and 87 women) newly diagnosed cases of brain tumor were distinguished.
- Using a Cox proportional hazards regression model, hazard ratio (HR) and 95% confidence intervals (95%CIs) for the relationship between coffee or green tea consumption and brain tumor risk were surveyed.
Results
- Researchers found a significant inverse relationship between coffee consumption and brain tumor risk in both total subjects (≥3 cups/day; HR=0.47, 95%CI=0.22-0.98) and in women (≥3 cups/day; HR=0.24, 95%CI=0.06-0.99), although the number of cases in the highest category was small.
- It was also observed that glioma risk tended to diminish with higher coffee consumption (≥3 cups/day; HR=0.54, 95%CI=0.16-1.80).
- As per the findings, no affiliation was seen between green tea and brain tumor risk.
