The effect of long-term intake of cis unsaturated fats on the risk for gallstone disease in men: a prospective cohort study.

Abstract

BACKGROUND

Monounsaturated and polyunsaturated fats act as inhibitors of cholesterol cholelithiasis in animal experiments.

OBJECTIVE

To examine the association between long-term intake of cis unsaturated fats and the incidence of gallstone disease in humans.

DESIGN

Prospective population-based cohort study.

SETTING

The Health Professional Follow-up Study.

PARTICIPANTS

45,756 men, age 40 to 75 years in 1986, who were free of gallstone disease.

MEASUREMENTS

Consumption of cis unsaturated fats was assessed starting in 1986 as part of the 131-item semi-quantitative food-frequency questionnaires. Questionnaires were mailed to participants every 2 years. The main outcome measure was self-reported newly diagnosed symptomatic gallstone disease.

RESULTS

During 14 years of follow-up, 2323 new cases of gallstone disease were documented. After adjustment for age and other potential risk factors, the relative risk for gallstone disease among men in the highest quintile of dietary intake of cis unsaturated fats compared with men in the lowest quintile was 0.82 (95% CI, 0.69 to 0.96; P for trend = 0.006). The relative risk among men in the highest quintile of polyunsaturated fat consumption compared with men in the lowest quintile was 0.84 (CI, 0.73 to 0.96; P for trend = 0.01), and the relative risk among men in the highest quintile of monounsaturated fat consumption compared with men in the lowest quintile was 0.83 (CI, 0.70 to 1.00; P for trend = 0.01).

LIMITATIONS

Outcomes were restricted to men with cholecystectomy or diagnostically confirmed but unremoved symptomatic gallstones.

CONCLUSIONS

A high intake of polyunsaturated and monounsaturated fats in the context of an energy-balanced diet is associated with a reduced risk for gallstone disease in men. For definitions of terms used in the text, see Glossary.
