The study aims to compare the effectiveness of individual and group nutrition education methods in improving key anthropometric and biochemical markers in drug-treated, overweight-obese hypertensive adults. The randomized trial included 170 patients with pharmacologically well-controlled primary hypertension and body mass index (BMI) ≥ 25 kg/m . For six months, the patients received six sessions, either one-to-one individual nutrition education (IE, = 89) or group education (GE, = 81), developed by dietitians. Anthropometric measurements, body composition, and fasting measures of biochemical parameters were obtained at baseline and after six months of intervention. 150 patients completed the nutrition education program. The IE group significantly improved in many parameters compared to the GE group, including weight ( < 0.001), waist circumference ( < 0.001), BMI ( < 0.001), systolic and diastolic blood pressure (BP) ( < 0.001), fasting plasma glucose ( = 0.011), oral glucose tolerance test (OGGT) ( = 0.030), and insulin resistance (homeostatic model assessment of insulin resistance, HOMA-IR) ( < 0.001). The groups did not differ in terms of total cholesterol, high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) concentrations. Individual nutrition education is more effective than group education in terms of improving anthropometric and biochemical indices in overweight-obese hypertensive adults.
