VEGOMNI: The Influence of the Nutritional Status of Women Between 30 and 45 Years of Age on the Condition of the Skin and Body Composition
Study Details
Study Description
Brief Summary
Goal is to investigate the differences in skin condition and body composition among women with different dietary habits aged 30-45 years. Study will be focused onto sub-groups of female subjects following omnivorous, vegetarian or vegan diet.
| Condition or Disease | Intervention/Treatment | Phase |

Detailed Description
Investigators will investigate differences among female subjects aged 30-45 years following one of the following diet for at least 3 years:
-
vegan
-
vegetarian
-
omnivorous
Study will focus into the differences in dermal protein density and dermal thickness, skin hydration and trans-epidermal water loss. Study will focus also into body composition, specifically into % of body fat and % of lean body weight.

Outcome Measures
Primary Outcome Measures
- Dermal density [baseline]
It will be measured on forearm using ultrasonography as score 0-100.
- Dermal thickness [baseline]
It will be measured on forearm using ultrasonography in micrometeres.
- Skin hydration [baseline]
It will be measured on forearm using Cortex DermaLab flat hydration probe in microsiemens.
- Skin elasticity [baseline]
It will be measured on forearm using Cortex DermaLab elasticity probe in MPa.
- Trans epidermal water loss [baseline]
It will be measured on forearm using Cortex DermaLab open-chamberTEWL probe.
- % of lean body weight [baseline]
It will be measured using Multiscan is a spectroscopy (BIS).
- % of body fat [baseline]
It will be measured using Multiscan is a spectroscopy (BIS).
