Study on Relationships Between Dietary Mineral Intakes and Blood Pressure and Blood Lipid in TB patients

摘要

The relationship between pulmonary tuberculosis (PTB) and diabetes mellitus (DM) has been previously attracted much attention. DM co-morbidity in PTB is associated with poor PTB treatment outcomes. The purpose of this study is to evaluate the food diversification levels, and the correlation between blood pressure, blood lipids and dietary intake of Ca, P, Mg, Fe, Zn, Cu and Mn. A total of 108 patients were eligible in the study and 36 of them were suffering from both TB and DM, 72 were TB only. Food types were detected by the investigation of dietary frequency, the intakes of minerals were assessed by using food intake survey for 3 days using a 24-h recall method. The result showed that energy and nutrients in TB patients with and without DM were significantly lower than the Recommended Nutrient Intake (RNI), formulated by the Chinese Nutrition Society. And correlation analysis showed that Zn dietary intake had a positive correlation with systolic BP and diastolic BP. And Ca, P, Mg, Fe, Zn, Cu and Mn were positively correlated with HDL cholesterol. Thus it is concluded that the dietary intake of minerals may play an important role in controlling blood pressure and lipids in TB patients.
