[Applicating food frequency questionnaire to assess the relationship between dietary polyunsaturated fatty acid intake and hypertension, dyslipidemia of Pumi nationality].

OBJECTIVE:The relationship between dietary polyunsaturated fatty acid intake and hypertension, dyslipidemia of Pumi nationality was studied,which provides a scientific basis of prevention and cure of hypertension and dyslipidemia. METHODS:A total of 376 Pumi nationality residents over 18 years in Lanping Bai Pumi nationality County of Nujiang state in Yunnan Province were selected as the research object, and a variety of food intake, intake frequency, the history of present illness and family history in recent years were collected by questionnaire survey.

RESULTS:The Pumi nationality residents' dietary fat intake was high, accounted for 198.5% of RNI. Energy ratio of three large capacity nutrient were imbalanced, but the per capita intake of n-3PUFA, EPA, DHA were not high. Hypertension prevalence of the Pumi nationality residents was 15.4%. Dyslipidemia type main performs that low high-density lipoprotein occupying 54. 8% , hypercholesterolemia occupying 8% , hypertriglyceridemia occupying 19.1%, and TC or TG anomaly crowd occupying 25%. PUFAs and dyslipidemia, n-6PUFA and hypertension were both showed a negative correlation. CONCLUSION:In order to prevent the occurrence and development of cardiovascular disease, to reduce blood lipids, the Pumi nationality residents should reduce the intake of grease and food rich in fat, and increase the intake of food rich in DHA, EPA.
