Reducing cardiometabolic disease risk dietary pattern in the Chinese population with dyslipidemia: a single-center, open-label, randomized, dietary intervention study

BACKGROUND: There is no specific dietary pattern for cardiometabolic health based on Chinese food culture. OBJECTIVES: The study aimed to develop and assess the efficacy of the reducing cardiometabolic disease risk (RCMDR) dietary pattern on cardiometabolic disease risk in the Chinese population with dyslipidemia. METHODS: In this single-center, open-label, randomized, 12-wk dietary intervention study, 100 adults aged 35-45 y with dyslipidemia were randomly assigned (1:1) to the RCMDR dietary pattern intervention or general health education control group. RESULTS: Compared with the control group, the RCMDR dietary pattern intervention resulted in a significantly lower clustered cardiometabolic risk score (primary outcome) (β: -0.17; 95% CI: -0.29, -0.05); diastolic blood pressure (β: -0.23; 95% CI: -0.40, -0.07); total cholesterol, LDL cholesterol, triglyceride (β: -0.27; 95% CI: -0.49, -0.04; β: -0.24; 95% CI: -0.41, -0.07; and β: -0.19; 95% CI: -0.35, -0.04, respectively); homocysteine (β: -0.19; 95% CI: -0.28, -0.09); waist circumference, waist-to-hip ratio, body fat percentage, body fat mass, visceral adipose tissue, visceral fat area, and a significantly higher lean body mass (β: -1.12; 95% CI: -1.65, -0.59; β: -1.01; 95% CI: -1.66, -0.36; β: -1.43; 95% CI: -1.87, -0.98; β: -0.98; 95% CI: -1.35, -0.60; β: -1.93; 95% CI: -2.75, -1.11; β: -6.52; 95% CI: -9.10, -3.95; and β: 1.24; 95% CI: 0.84, 1.65, respectively). CONCLUSIONS: Compared with the control group, the RCMDR dietary pattern intervention lowers cardiometabolic risk, blood lipids, blood pressure, abdominal obesity, and circulating homocysteine concentration among Chinese population with dyslipidemia.
