Summary
Nutritional counseling by doctors and dietitians significantly improved weight and blood pressure in overweight patients with hypertension or type 2 diabetes. This integrated approach proved effective for health promotion.
Area of Science:
- Public Health
- General Practice
- Nutritional Science
Background:
- Overweight, hypertension, and type 2 diabetes are prevalent conditions requiring effective management strategies.
- Nutritional counseling is a key component in managing these chronic diseases.
- Integrated care models may enhance patient outcomes.
Purpose of the Study:
- To evaluate the clinical and cost-effectiveness of nutritional counseling for patients with overweight, hypertension, and/or type 2 diabetes.
- To compare outcomes between a doctor/dietitian intervention group and a dietitian-only group.
Main Methods:
- Randomized controlled trial involving 273 patients screened for overweight, hypertension, or type 2 diabetes.
- Intervention groups received six dietitian counseling sessions over 12 months.
- One group involved doctor-led patient invitation and progress reviews.
Main Results:
- Both intervention groups achieved significant reductions in weight and blood pressure compared to the control group.
- The doctor/dietitian group showed higher program completion rates.
- Average weight loss was 6.7 kg in the doctor/dietitian group ($A9.76/kg) and 5.6 kg in the dietitian group ($A7.30/kg).
Conclusions:
- General practitioners and dietitians collaborating can effectively improve weight and blood pressure.
- Health promotion strategies involving integrated care show significant clinical benefits.
- This model offers a viable approach for managing common chronic conditions.
