The Influence of the Nutritional Status of Women Between 30 and 45 Years of Age on the Condition of the Skin and Body Composition

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.

About this study

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.

Treatment and study plan

dietary habit

Other

As it is observational study, women that follow three different dietary patterns will be inlcuded .

Primary outcomes

  1. Dermal density

    Time frame: baseline

    It will be measured on forearm using ultrasonography as score 0-100.

  2. Dermal thickness

    Time frame: baseline

    It will be measured on forearm using ultrasonography in micrometeres.

  3. Skin hydration

    Time frame: baseline

    It will be measured on forearm using Cortex DermaLab flat hydration probe in microsiemens.

  4. Skin elasticity

    Time frame: baseline

    It will be measured on forearm using Cortex DermaLab elasticity probe in MPa.

  5. Trans epidermal water loss

    Time frame: baseline

    It will be measured on forearm using Cortex DermaLab open-chamberTEWL probe.

  6. % of lean body weight

    Time frame: baseline

    It will be measured using Multiscan is a spectroscopy (BIS).

  7. % of body fat

    Time frame: baseline

    It will be measured using Multiscan is a spectroscopy (BIS).
