Insights
Drinking coffee is linked to higher serum cholesterol levels in adults. This study found a significant positive association, even after accounting for other lifestyle factors.
Area of Science:
- Cardiovascular Health
- Nutritional Epidemiology
- Clinical Research
Background:
- Hypertension Detection and Follow-up Program involved 9,043 hypertensive adults.
- Previous research on coffee consumption and serum cholesterol has yielded mixed results.
- Understanding dietary impacts on cardiovascular markers is crucial for public health.
Purpose of the Study:
- To investigate the association between coffee consumption and serum cholesterol levels.
- To determine if this association persists after controlling for potential confounding variables.
Main Methods:
- Longitudinal study of 9,043 hypertensive adults (aged 30-69) from 1973-1974 to 1975-1976.
- Serum cholesterol measured at baseline and two-year follow-up.
- Dietary intake, including coffee, tea, and cola, assessed via food frequency questionnaire.
- Multiple regression analysis used to control for age, race, sex, smoking, and other factors.
Main Results:
- A significant positive association was found between coffee consumption and serum cholesterol levels (p < 0.05).
- No significant relationship was observed between serum cholesterol and tea, cola, or decaffeinated coffee intake.
- Total caffeine intake did not show a significant association with serum cholesterol levels.
Conclusions:
- Regular consumption of coffee is associated with elevated serum cholesterol levels in hypertensive adults.
- The observed association appears specific to coffee and not other caffeinated beverages or total caffeine intake.
- Further research may be warranted to elucidate the mechanisms behind this coffee-cholesterol relationship.
Abstract:
The relation between coffee consumption and serum cholesterol level was investigated in a group of 9,043 hypertensive adults who were in the Hypertension Detection and Follow-up Program. In this study, men and women aged 30-69 years at baseline (1973-1974) had their serum cholesterol level measured at the two-year examination (1975-1976). Information about coffee, tea, and cola consumption was also obtained at that time from a food frequency questionnaire. The relation of coffee consumption and serum cholesterol level with potentially confounding variables including age, race, sex, diuretic status, diastolic blood pressure, cigarette smoking, relative weight, physical activity, stress, and education level was examined. When these variables were entered into a multiple regression equation, a positive association with coffee consumption and serum cholesterol level (p less than 0.05) was present. There was no significant relation between serum cholesterol level and consumption of tea, cola, or decaffeinated coffee--the other major contributors of caffeine to the diet--or total caffeine intake. This study indicates a significant positive relation between coffee consumption and serum cholesterol level.
