Dietary practices and lipid intake in relation to plasma lipid profile in Hong Kong Chinese

Abstract

Objective: To study dietary lipid intake and plasma lipid profile of the Hong Kong Chinese population as part of a territory wide survey on cardiovascular risk factors. Design: Randomised age and sex stratified survey. Subjects: 1010 subjects aged 25–74 y (500 men, 510 women). Measurements: A food frequency method with food tables compiled for Hong Kong was used for nutrient quantitation, while a separate questionnaire was used to examine dietary practices. Plasma lipid profile was estimated using standard laboratory methods. Results: Total calorie, fat, saturated fatty acid (SFA), poly- and mono-unsaturated fatty acid (PUFA and MUFA), and cholesterol intake were higher in men; however when adjusted for calorie intake no difference was observed. Men had lower intake of PUFA as percentage of total energy and a higher Hegsted Score compared with women. Subjects consuming beans twice or more per week had lower total cholesterol and LDL-cholesterol concentrations. Overall, the population dietary intake was close to the ideal for cardiovascular health: percentage fat not greater than 30% of the total calorie intake, saturated fat intake not greater than 10% of calories, and cholesterol less than 180 mg/1000 Kcal. Conclusion: The dietary pattern for Hong Kong Chinese appear to be satisfactory with respect to cardiovascular health. Sponsorship: Hong Kong Health Services Research Grant.
