Background<\/strong><\/p>\n

Fitzpatrick skin phototype<\/a> (FSPT) is the most common method used to assess sunburn risk and is an independent predictor of skin cancer risk. Because of a conventional assumption that FSPT is predictable based on pigmentary phenotypes, physicians frequently estimate FSPT based on patient appearance.<\/p>\n

Objective<\/strong><\/p>\n

We sought to determine the degree to which self-reported race and pigmentary phenotypes are predictive of FSPT in a large, ethnically diverse population.<\/p>\n

Methods<\/strong><\/p>\n

A cross-sectional survey collected responses from 3386 individuals regarding self-reported FSPT, pigmentary phenotypes, race, age, and sex. Univariate and multivariate logistic regression<\/a> analyses were performed to determine variables that significantly predict FSPT.<\/p>\n

Results<\/strong><\/p>\n

Race, sex, skin color, eye color, and hair color are significant but weak independent predictors of FSPT (P<\/em><\/a> < .0001). A multivariate model constructed using all independent predictors of FSPT only accurately predicted FSPT to within 1 point on the Fitzpatrick scale with 92% accuracy (weighted kappa statistic<\/a> 0.53).<\/p>\n

Limitations<\/strong><\/p>\n

Our study enriched for responses from ethnic minorities and does not fully represent the demographics of the US population.<\/p>\n

Conclusions<\/strong><\/p>\n

Patient self-reported race and pigmentary phenotypes are inaccurate predictors of sun sensitivity as defined by FSPT.<\/strong> There are limitations to using patient-reported race and appearance in predicting individual sunburn risk.<\/p>\n
