Patient empowerment and the Mediterranean diet as a possible tool to tackle prediabetes associated with overweight or obesity: a pilot study.

AIM: The objective of this study was to investigate the effect of implementation of short-term patient empowerment as applied to Mediterranean diet (MD) adherence on metabolic and anthropometric parameters in prediabetic overweight or obese subjects. METHODS: The sample included 42 subjects with prediabetes, aged 18-75 years and with body mass index (BMI) > 25 kg/m2, who received dietary advice on MD by nutritionists during session groups every 2 weeks for 4 months. Data on energy caloric intake and macronutrient consumption were collected using a 7-day food diary record. Adherence to MD was investigated through the PREvención con DIeta MEDiterránea (PREDIMED) questionnaire. No advice was given regarding caloric restriction and physical activity. At baseline and at the end of the study, each subject underwent anthropometric, metabolic, and nutritional assessments. RESULTS: Approximately 40.5% of subjects had achieved restoration of normal glucose tolerance by the end of the study. Fasting plasma glucose, glycated hemoglobin (HbA1C), BMI, waist circumference, blood pressure, visceral adiposity index, triglycerides, and total and LDL cholesterol levels were significantly decreased, while HDL cholesterol had significantly increased by the end of the study. The subjects significantly increased adherence to MD, as assessed by the PREDIMED questionnaire at follow-up. A reduction of prevalence of the metabolic syndrome was also reported. Interestingly, the PREDIMED score correlated with HbA1C values at follow-up, after adjusting for BMI and total caloric intake. CONCLUSIONS: Implementation of short-term patient empowerment as applied to MD adherence was shown to improve anthropometric and metabolic parameters in prediabetic overweight or obese subjects. This is of considerable importance, given that diet must be the cornerstone of treatment in patients at high risk of developing type 2 diabetes.

Improving Self-Management of Type 2 Diabetes in Overweight and Inactive Patients Through an Educational and Motivational Intervention Addressing Diet and Physical Activity: A Prospective Study in Naples, South Italy.

INTRODUCTION: Nutrition and physical activity are key elements in the prevention and management of type 2 diabetes. A community-based, multidisciplinary educational intervention aimed to improve quality of life and disease self-management in sedentary, overweight/obese type 2 diabetic patients was implemented in Naples, South Italy. METHODS: The 9-month intervention included a motivational program, a nutrition program, and an exercise program. Satisfaction, worry, and embarrassment regarding their condition, together with disease-related behaviors and propensity towards physical activity, were evaluated through a validated questionnaire before and after the intervention; health status perception was evaluated through the short-form 12 questionnaire. Changes in HbA1c level and weight were also checked. RESULTS: A significant improvement (p < 0.05) was registered in behaviors related to the management of hypoglycemic crisis and food choice; in nearly all the items related to living with the disease (p < 0.01); and in health status perception (p < 0.01). The adoption of healthy behavior was more common among women (OR 2.17, 95% CI 1.09, 3.02) and persons with higher educational levels (OR 1.26, 95% CI 0.83, 2.17; OR 1.54, 95% CI 0.56, 2.27). About 30% of participants did not modify their emotional status after the intervention. Although not significantly (p = 0.18), the trust of patients towards physical activity increased at the end of the study, together with their active lifestyle (p < 0.01) and with the decrease of perceived barriers (p < 0.01). A significant improvement was registered in glycemic control and weight status (p < 0.01). CONCLUSIONS: The intervention was feasible and effective in addressing diet and physical activity among participants, giving consequent improvements in health status. Similar educational interventions including a training program for people with diabetes should be standardized and adopted by the Italian National Health System.
