Evaluation of the severity of striae distensae using the new scoring system

Abstract

Background: Striae distensae (SD) is a harmless skin disorder that can cause cosmetic and psychological problems. Until now, no easy-to-use, useful and non-invasive method can be used to determine the severity of SD. The scoring system can be used as a guide for selecting and administering effective therapy for striae distensae. This study aimed to assess the severity of striae distensae using INA score. Methods: This research was a descriptive observational study with a cross-sectional approach involving 72 female health workers at the Universitas Sumatera Utara Hospital. The diagnosis of stretch marks is made through history and physical examination. We did the whole body examination for scoring of striae distensae. This research has been approved by the Research Ethics Commission of the Universitas Sumatera Utara. Results: A new scoring system, namely the INA score, to assess the severity of striae distensae at the mammae, axilla, abdomen, femoral, gluteus, and popliteal locations. The assessment of the INA score based on the entire region of the study subjects was obtained at a mild degree (54.2%). The characteristics of majority of the subjects were in the age range of 18-25 years (93.1%) and had a family history of striae distensae (54.2%). The distribution of the majority of striae distensae locations is in the femoral and gluteus region (47.2%). Based on each region, the majority of the subjects had striae distensae with severe degree in the mammae (20.8%), abdomen (8.3%), femoral (90.3%), gluteus (94.4%), and popliteal (22.2%);. In comparison, the axilla was dominant with a moderate degree (5.5%). Conclusion: The new scoring system named INA score assesses the severity of striae distensae at the mammary, axillary, abdominal, femur, gluteus and popliteal locations.
