Abstract

Background:

Striae have been reported to be one of the most common skin changes and a commonly encountered esthetic problem.

Objectives:

To analyze risk factors of striae not associated with pregnancy and verify if body build and composition influence striae distensae (SD) occurrence and visibility.

Methods:

Eighty female students (40 with striae (the mean age 23.9 years, SD 2.05 years) and 40 without these lesions (24.7 years, SD 6.2 years)) were included in the study. The subjects were asked to fill out a questionnaire including questions concerning risk factors of SD. Body build and composition were examined using Tanita SC-331S Body Composition Analyzer.

Results:

Women without striae more often reported a history of intended weight loss (P < .0001), less frequently had a history of contraceptives intake (P < .001) and more often their family history of striae was negative or unknown (P = .01). Multivariate analysis including body build and composition parameters indicated BMI as risk factor of SD (P = .021; OR =1.155, 95% CI 1.006; 1.325).

Conclusions:

History of contraceptives intake and a family history of striae are risk factors of SD occurrence, while weight loss can reduce the risk of these lesions. BMI appeared to be the risk factor of striae visibility, especially in abdomen, but not on the buttocks. Further clinical researches are needed to examine the pathophysiology of this condition and to inform patients about the possibility to reduce the risk of striae occurrence.
