There is no validated instrument to assess the clinical severity of striae distensae. Here, we aimed to develop a striae distensae severity scale.
After a Delphi-based consensus, 15 items related to striae severity were assessed in 110 areas (breasts, abdomen, and buttocks) from 45 participants. The items were analyzed through a partial least squares model to select the most important variables. To assess the reliability of the scale, 43 areas were retested.
Of the 110 areas evaluated, 34 were breasts, 24 abdomens, and 52 buttocks. Striae were considered mild in 30% of the evaluations, moderate in 33%, severe in 21%, and extremely severe in 16%. The final model was composed by: width of the widest striae, width of the striae with the most frequent pattern, atrophy, number of affected quadrants, distribution (multiple or isolated), hypo or hyperchromia and topography. The scores of the scale demonstrated a high correlation with the clinical classification (rho = 0.77). There was a high agreement in the scores from the reassessed areas (intraclass correlation coefficient = 0.90).
An objective and reliable scale to assess the clinical severity of striae distensae on the breasts, abdomen, and buttocks was developed.
目前尚无评估膨胀纹临床严重程度的有效工具。在此，我们旨在开发一种膨胀纹严重程度量表。
在基于德尔菲法的共识后，从 45 名参与者的 110 个部位（乳房、腹部和臀部）评估了 15 个与膨胀纹严重程度相关的项目。通过偏最小二乘模型对这些项目进行分析，以选择最重要的变量。为了评估该量表的可靠性，对 43 个部位进行了重测。
在评估的 110 个部位中，有 34 个是乳房，24 个是腹部，52 个是臀部。30%的评估结果认为膨胀纹为轻度，33%为中度，21%为重度，16%为极重度。最终的模型由最宽纹的宽度、最常见模式纹的宽度、萎缩、受累象限数量、分布（多部位或孤立部位）、色素减退或色素沉着过度以及部位组成。该量表的评分与临床分类高度相关（rho=0.77）。重测部位的评分具有很高的一致性（组内相关系数=0.90）。
我们开发了一种用于评估乳房、腹部和臀部膨胀纹临床严重程度的客观、可靠的量表。
