Clinical Trial Summary

The prevalence of obesity in the developed world has increased markedly over the last 20 years. Considering the prevalence of obese and overweight adult subjects, and the fact that pregnancy itself induces a state of insulin resistance and inflammation, maternal obesity may be the most common health risk for the developing fetus. It is well established that what we eat has a major impact on our health. However, there is growing evidence to suggest that diet during pregnancy and lactation may be particularly important as not only does it influence the health of the mother, it may have a permanent effect on the health of her children and even her grandchildren. The concept that environmental factors, such as nutrition during early development, influence both our health span and lifespan has been termed the developmental origins of health and disease hypothesis.

The objective of the study are:

- to compare subjects with frailty (condition developed with ageing) with controls and characterize the unhealthy aged condition with the measurements described below

- to examine if signs of frailty can be reversed by lifestyle induced modifications (exercise training programme) of its primary components (IR, sarcopenia, psychological profile) in offspring of overweight/obese (OOM) vs lean mothers (OLM).

The study consists of 37 frail old subjects, age ≥ 65 sub-grouped in 17 OOM, and 20 OLM and 11 non frail controls. These subjects will be studied with positron emission tomography (PET), computed tomography (CT), magnetic resonance imaging (MRI) and spectroscopy (MRS) and ultra sounds (US). In addition functional MRI (fMRI) will be performed. Adipose tissue biopsies will be taken.

Subjects will undergo characterization of biohumoral markers, a 75 g oral glucose tolerance test, imaging biomarkers (PET/CT, US, fMRI-MRS), genetic biomarkers (DNA and telomere damage) and inflammatory biomarkers (macrophage infiltration) before and after the 4-month lifestyle intervention period (physical exercise). By PET/CT it will be measured tissue-specific IR in skeletal muscle, adipose tissue, liver, myocardium and targeted brain regions. MRS will be used to measure organ steatosis in the skeletal muscle and liver, MRI will be used to measure fat masses in abdominal areas, and fMRI will be performed to assess activation in brain regions regulating cognition and appetite/energy control. US will be used to assess cardiovascular markers (IMT, strain and function).
