Assessment of predictors of sun sensitivity as defined by Fitzpatrick skin phototype in an Ecuadorian population and its correlation with skin damage

Abstract:

Background: The Fitzpatrick skin phototype scale (FSPTS) is a widely used instrument to assess skin type. Methods: A cross-sectional survey collected responses from 254 subjects from Quito regarding self-reported FSPTS, gender, age, education, and tobacco and alcohol consumption. Univariate and multivariate logistic regression analyses were performed to determine if ethnicity, hair color, and eye color significantly predict FSPTS. In addition, we studied the correlation between FSPTS and the SCINEXA scale with Pearson’s correlation coefficient. Results: Ethnicity, eye color, and hair color are significant independent predictors of FSPTS (p < 0.0001). Conclusions: Patient self-reported race and pigmentary phenotypes are inaccurate predictors of sun sensitivity as defined by Fitzpatrick skin phototype. Our study does not fully represent the population of the country. There are limitations to …
