Abstract
Background
Striae distensae (SD) or stretch marks are a common dermatological condition where the dermis becomes scarred. This phenomenon is associated with many risk factors. This study aimed to evaluate the clinical variables and risk factors in patients with SD in Riyadh, Kingdom of Saudi Arabia (KSA).
Methods
A cross-sectional study was conducted to assess the clinical variables and risk factors for stretch marks among adults in Riyadh, KSA. An electronic questionnaire with an informed consent section was distributed randomly to a sample of adult patients in Riyadh city, KSA, from April to June 2021. A sample size of 512 participants was calculated using the Cochran formula (n = Z2pq/e2), considering 95% confidence and precision of at least ±5%. A 95% confidence level yielded Z values of 1.96, per the normal tables.
Results
A total of 512 participants were included in this study. This study found that 41.4% of the participants were aged 15 to 25 years of which, 70.4% of the participants were females, and 38.2% had a body mass index (BMI) of 24 or more. More than half of the participants (54.0%) indicated white skin color. The most prevalent area of striae, as reported by the participants, was the abdomen (57%). Around 19.1% of the participants with stretch marks stated that they were smokers, and 23.9% stated that they were obese o, had a chronic condition such as hypertension or diabetes mellitus. The majority of the participants (70.5%) had a family history of stretch marks.
Conclusions
This study showed that the prevalence of stretch marks was higher in females, younger participants, smokers, participants with a family history of stretch marks, and participants with a higher BMI and multiparity. More studies should be conducted to assess the correlations between these factors and the presence of stretch marks, and their influence on the quality of life of individuals.
