Beneficial Effects of Dietary and Lifestyle Change in Overweight and Obese Subjects
An observational study of Overweight and Obesity and Cardiovascular Diseases, run by University of Bari at 1 site in Italy.
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

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 participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Treated | Counselling, personalized dietary strategy aimed at increasing the adherence to Mediterranean diet, personalized physical activity program with a personal trainer, use of digital tools (i.e., games, apps) aimed at improving the adherence to dietary/lifestyle indications. | |
| Control | generic dietary indications oriented to weight reduction; generic invitations to increase physical activity, routine monitoring |
What is being measured
The primary outcome is the main question the study is designed to answer.
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
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)
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
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
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
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

Questions about this trial
What is this clinical trial studying?
An observational study of Overweight and Obesity and Cardiovascular Diseases, run by University of Bari at 1 site in Italy.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 7 Jul 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Piero Portincasa (+39-080-5592731, piero.portincasa@uniba.it), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Effects of treatments on Body Mass Index and waist circumference (time frame: 24 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05447351, which also lists 20 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jul 2022.
