| Popis: | Background Estimation of gestational age (GA) is important to make timely decisions and provide appropriate neonatal care. Clinical maturity scales to estimate GA have used skin texture and color to assess maturity at birth facing situations of the uncertainty of pregnancy dating. The size and darkness of the areola around the nipple to grade skin characteristics are based on visual appearance. The melanin index (M‐Index) is an optical skin parameter related to the melanin content in the tissue. This study is aimed to associate the M‐Index of the skin with the GA. Methods A cross‐sectional study evaluated 80 newborns at birth. A photometer device quantified the skin pigmentation on the areolae, forearms, and soles. Paired average differences of M‐Index were compared among the three body sites. The skin M‐Indexes were compared between subgroups of newborns until 34 weeks or with 34 and more. Results The skin over the areola had the highest values of M‐Index compared with the forearm or sole areas (P |
