Ce. Lewis et al., INCONSISTENT ASSOCIATIONS OF CAFFEINE-CONTAINING BEVERAGES WITH BLOOD-PRESSURE AND WITH LIPOPROTEINS - THE CARDIA STUDY, American journal of epidemiology, 138(7), 1993, pp. 502-507
The authors examined associations of caffeine and caffeinated beverage
intakes with blood pressure and with lipoproteins in 5,115 black and
white men and women aged 18-30 years during 1985-1986. Caffeine and be
verage intakes were not consistently associated with blood pressure in
analyses controlling for race, sex, Keys score, sucrose intake, physi
cal activity, oral contraceptive use, body mass index, alcohol use, ag
e, and smoking. Associations of caffeine and beverage intakes with cho
lesterol, triglycerides, high-density lipoprotein cholesterol, and hig
h-density lipoprotein2 cholesterol were also inconsistent. There is li
ttle or no association of caffeine with lipoproteins or with blood pre
ssure in this cohort of healthy young adults.
