Why the study?

Does a diet rich in polyunsaturated fatty acids reduce cardiovascular risk factors and new coronary heart disease morbidity in middle-aged men?

Comparison

Diet relatively rich in polyunsaturated fatty… vs Control group of 463 men of similar age with…

Implication

Should not yet change dietary practice; leaves open whether PUFA-rich diets causally reduce CHD risk in middle-aged men.

Key Points

To determine the long-term impact of a diet rich in polyunsaturated fatty acids on coronary heart disease risk factors and disease morbidity in middle-aged men.
A controlled dietary intervention assigned 814 men aged 40 to 59 years to a diet relatively rich in polyunsaturated fatty acids.
An age-matched control group of 463 men was followed concurrently for comparison.
Serum cholesterol, obesity, hypertension, and new coronary heart disease morbidity were tracked across four to five years of follow-up.
The intervention diet significantly lowered serum cholesterol levels compared to baseline, sustaining these reductions for up to five years.
After four years, prevalence rates of obesity, hypertension, and hypercholesterolemia were significantly lower in the experimental group than in the control group, where rates remained stable.
A statistically significant reduction in morbidity from new coronary heart disease was observed in the experimental diet group compared to the control group.

Structured PICO

Does a diet rich in polyunsaturated fatty acids reduce cardiovascular risk factors and new coronary heart disease morbidity in middle-aged men?

Population

1,277 men aged 40 to 59 years old (814 in the intervention group, 463 in the control group).

Intervention

Diet relatively rich in polyunsaturated fatty acids (Anti-Coronary Club Program) for up to 5 years.

Comparator

Control group of 463 men of similar age with stable prevalence of conditions (presumably usual diet).

Outcome

Prevalence of risk factors (obesity, hypertension, and hypercholesterolemia) and morbidity from new coronary heart disease at 4 to 5 years.surrogate

A diet rich in polyunsaturated fatty acids significantly improves cardiovascular risk factors and reduces new coronary heart disease morbidity in middle-aged men.
