Trial summary

Obesity and overweight are noncommunicable diseases with increasing incidence in children, adolescents and adults. In 2016, more than 1.9 billion adults aged 18 and over were overweight and over 650 million were obese (WHO). Read more about this study

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages Any age
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Study population: Enrolled in the study will be 200 overweight or obese adult patients (comparable sex ratio) entering the outpatient clinic for metabolic diseases. Subjects will be randomized in two groups (i.e., n=100 treated and n=100 controls). For an unpaired t-test (i.e., comparison of two groups), 50 is the minimum sample size needed in each group to obtain a power of 0.80, when the effect size is medium and a significance level of 0.05 is employed.

About this study

Official title: Effects of Personalized Dietary and Lifestyle Treatments on the Reduction of Cardiovascular and Metabolic Risk in Overweight and Obese Patients

Obesity and overweight are noncommunicable diseases with increasing incidence in children, adolescents and adults. In 2016, more than 1.9 billion adults aged 18 and over were overweight and over 650 million were obese (WHO). In the EU-27 (Eurostat data), 45.7% of women and 60.2% of men were overweight, while 16.3% and 16.8%, respectively, were obese. The growing incidence of overweight and obesity generate worldwide increasing incidence of related conditions as cardiovascular diseases, diabetes, metabolic disorders, and cancer, with relevant socio-economical (increase in health costs, increase in disabilities) and environmental consequences (unsustainability of food models, increase in ecological footprint, worsening of climate changes). A transformation of food systems and individual behaviours are necessary to improve the quality of life and the sustainability of lifestyle, which should be oriented at preventing o treating overweight and obesity.

Read the detailed description

The study is aimed to measure the beneficial effects of specific dietary models (i.e., Mediterranean Diet) and healthy lifestyle (i.e., controlled physical activity) in reducing body/organ fat accumulation and in the improvement of metabolic health. A comprehensive and combined analysis of these effects (mainly following personalized strategies and close follow-up) on pathogenic mechanisms affecting cardiovascular and metabolic risk, pro-inflammatory status and intestinal permeability in the medium-long term is still lacking.

During the study, overweight/obese subjects (i.e. Body Mass Index equal or higher to 25Kg/m2) will be assessed at basal and monitored during a 24 months follow-up

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Effects of treatments on Body Mass Index and waist circumference

    waist circumference will be measured and expressed in cm. weight and height will be combined to report BMI in kg/m^2. Measurements will be taken at enrollment and during follow-up.

    Measured: 24 months

  2. Effects of treatments on visceral fat

    Measurement of visceral fat by ultrasonography (expressed in mm) will be performed at baseline and during follow-up

    Measured: 24 months

Secondary outcomes (4)
  1. Change in metabolic indices and in hormones involved in the regulation of glucose metabolism

    gluco-lipid profile, adipokines, insulinemia, HOMA index will be measured at baseline and during the follow-up

    Measured: 24 months

  2. Change in hormones involved in nutrient sensing

    GLP-1, GIP, total and acylated ghrelin, PYY will be measured at baseline and during the follow-up

    Measured: 24 months

  3. Effects of microbiota and metabolome

    profiling of gut microbiota and assessment of metabolome will be assessed in enrolled subjects at baseline and during follow-up

    Measured: 24 months

  4. Effects on intestinal permeability

    markers of intestinal permeability (blood / urine dosage of LPS, zonulin) urinary dosage of sugars with selective gastrointestinal absorption, aimed at evaluating intestinal permeability at the gastric, ileal and colic level. Assessments will be performed at baseline and during the follow-up

    Measured: 24 months
