[Show abstract][Hide abstract] ABSTRACT: To prepare a dietary recommendation for young Japanese for the prevention of coronary heart disease, we surveyed the dietary habits, serum lipids, serum fatty acids and blood pressure levels among male and female students.
In this study, 175 male and 246 female university students were interviewed for the frequency of consumption of selected food items and the habit of skipping breakfast. Serum fatty acids were analyzed by gas chromatography.
The frequencies of consumption of dishes cooked with oil and intake of vegetables were higher in female students than in male students. Serum n-6 polyunsaturated fatty acids were slightly higher in females students than in male students while that of serum n-3 polyunsaturated fatty acids was 6.4% in both sexes. For both males and females, those who skipped breakfast at least once a week were less likely to consume vegetables and fruits than those who did not. Female students who skipped breakfast were also less likely to consume fish and had lower composition of n-3 polyunsaturated fatty acid and higher systolic and diastolic blood pressure levels than males. For female, the intake of milk and dairy products correlated inversely with systolic blood pressure levels and the intake of n-3 polyunsaturated fatty acids correlated inversely with diastolic blood pressure levels. For males, the intake of fruits and consumption of dishes cooked with oil correlated inversely with systolic and diastolic blood pressure levels.
Our findings suggest that increased intake of fish, milk and dairy products, fruits and vegetables from early adulthood and a regular dietary pattern are important to reduce the risk factors for coronary heart disease.

[Show abstract][Hide abstract] ABSTRACT: Westernization of lifestyles among Japanese, in particular among young generations, is a matter of concern for future increase in coronary heart disease. We surveyed a total of 349 male university students to examine changes in lifestyles and coronary risk factors in campus life. We compared dietary habits and serum fatty acid compositions as well as other coronary risk characteristics between freshmen (n=171) and fourth-year (senior) students (n=178). Serum fatty acid compositions and dietary intakes of selected foods as well as serum lipids, blood pressures and physical characteristics were examined at the 1996 and 1997 annual health examinations.Compared to freshmen, senior students had a lower frequency of fish, vegetable, milk and egg intake, and a higher frequency of oil and fat intake. The proportions of serum saturated and monounsaturated fatty acids were significantly higher among senior students than among freshmen, whereas the proportion of serum polyunsaturated fatty acids was significantly lower among senior students than among freshmen. Senior students also had higher systolic and diastolic blood pressures, percent body fat, smoking rate and alcohol usage than freshmen. Mean body weight and mean body mass index were not different between the two groups.Senior students generally showed Westernized dietary habits and higher coronary risk profiles than freshmen as indicated by the change of serum fatty acid compositions. Modification of these dietary habits and lifestyles may be important for the prevention of future CHD among Japanese young adults.
