Effectiveness of Individual Nutrition Education Compared to Group Education, in Improving Anthropometric and Biochemical Indices among Hypertensive Adults with Excessive Body Weight: A Randomized Controlled Trial

Abstract

Objective: 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. Methods: The randomized trial included 170 patients with pharmacologically well-controlled primary hypertension and body mass index (BMI) ≥ 25 kg/m2. For six months, the patients received six sessions, either one-to-one individual nutrition education (IE, n = 89) or group education (GE, n = 81), developed by dietitians. Anthropometric measurements, body composition, and fasting measures of biochemical parameters were obtained at baseline and after six months of intervention. Results: 150 patients completed the nutrition education program. The IE group significantly improved in many parameters compared to the GE group, including weight (p < 0.001), waist circumference (p < 0.001), BMI (p < 0.001), systolic and diastolic blood pressure (BP) (p < 0.001), fasting plasma glucose (p = 0.011), oral glucose tolerance test (OGGT) (p = 0.030), and insulin resistance (homeostatic model assessment of insulin resistance, HOMA-IR) (p < 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. Conclusion: Individual nutrition education is more effective than group education in terms of improving anthropometric and biochemical indices in overweight-obese hypertensive adults.

Effects of the Modified DASH Diet on Adults With Elevated Blood Pressure or Hypertension: A Systematic Review and Meta-Analysis

“…However, the results were inconsistent. Some studies reported that the modified DASH diet could reduce BP (18)(19)(20), body mass index (BMI) (19), blood sugar (18), and lipidemia (21); while other studies suggested the modified DASH diet might increase BP (22), blood sugar (18), and insulin resistance (23). Thus, we conducted a systematic review and meta-analysis to assess the efficacy of modified DASH diet for hypertension patients.…”

Improved Nutritional Knowledge in the Obese Adult Population Modifies Eating Habits and Serum and Anthropometric Markers

“…The same was seen to occur with waist circumference and the rest of the anthropometric ratios. The recorded weight reduction of 3% was less than that found in other longitudinal studies, despite the fact that 60% of the sample was engaged in moderate weekly physical activity [48][49][50]. Multicomponent interventions achieve better outcomes than those based on other intervention modalities, though interventions that achieve small reductions in daily calories from fat also afford reductions in weight, BMI and waist circumference [51].…”

Nutritional concepts of health promotion in sub urban community: focus on obesity and hypertension

“…19 By enhancing anthropometric and biochemical indicators in people who are overweight, obese, and hypertensive, dietitian-provided dietary counseling can dramatically enhance the management of patients with obesity and hypertension. 51 It has been estimated that 60-70% of adult hypertension is caused by adiposity, and excess fat is linked to increases in arterial pressure. Peripheral body fat has less of an impact on blood pressure than central body fat, which is linked to insulin resistance and dyslipidemia.…”
