Body Composition, Skin Condition
Conditions
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.
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.
Interventions
OTHERdietary habit
As it is observational study, women that follow three different dietary patterns will be inlcuded .

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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). |
