Racial, ethnic minorities often don’t practice sun protective behaviors

Despite higher rates of skin cancer morbidity and mortality among racial and ethnic minorities, affected adults often are not recognizing their risks or taking preventive measures, said Costner McKenzie, BA, and Roopal V. Kundu, MD of Northwestern University, Chicago.

In a multivariable logistic regression analysis, Mr. Costner and Dr. Kundu sampled data of 33,672 adults included in the 2015 National Health Interview Survey. Data from the 2010 U.S. Census Bureau also were used to develop sample weights representative of the U.S. population. There was a survey of a smaller sample of adults who were determined to have sun-sensitive skin. The findings were published in the Journal of the American Academy of Dermatology.

Sun sensitivity was determined by skin reaction to 1 hour of unprotected sun exposure. Those who self-reported severe sunburn with blisters or moderate sunburn with peeling were determined to be sun sensitive.

The sample surveyed comprised 3,665 women (41%) and 5,287 men (59%). Of these, 82% were white non-Hispanic, 3% black non-Hispanic, 3% Asian non-Hispanic, 11% Hispanic, and 1% other non-Hispanic.

Mr. McKenzie and Dr. Kundu found that non-Hispanic black, non-Hispanic Asian, and Hispanic adults were less likely to use sunscreen than were non-Hispanic white adults (adjusted odds ratio [aOR], 0.43, 0.54, and 0.70, respectively). Non-Hispanic blacks and Hispanics also were less likely to use sunscreen greater than SPF 15 (a0R, 0.39 and 0.64, respectively). Non-Hispanic blacks, non-Hispanic Asians, and Hispanics were less likely to have ever had a total body skin examination (aOR, 0.29, 0.21, and 0.39, respectively).

Yet these same three groups were more likely to wear long sleeves outside (non-Hispanic blacks aOR, 1.96, non-Hispanic Asians aOR, 2.09, and Hispanics aOR, 2.29). In addition, non-Hispanic Asians and Hispanics were more likely to shelter in the shade on warm, sunny days (aOR, 1.63 and 1.85, respectively).

Citing recent literature, the authors noted that although skin cancer is the most commonly diagnosed cancer, it is not typically thought of as a disease that afflicts minority populations, especially among minorities themselves, who do not generally recognize their own risk (Arch Dermatol. 2009;145[2]:207-8). In fact, morbidity and mortality from skin cancer actually are greater in racial and ethnic minorities (J Am Acad Dermatol. 2016;75[5]:983-91; J Am Acad Dermatol. 2006;55[5]:741-60), despite greater incidence of skin cancer among white adults.

“This study highlights the impact of race and ethnicity on sun protective behaviors,” said Mr. McKenzie and Dr. Kundu. Cultural beliefs, stigma, personal preferences, as well as a lack of “knowledge-based interventions” specifically intended for minorities could be responsible for the observed differences between population groups, they speculated.

The primary limitations of the study were its cross-sectional design and the use of self-reported data, the authors noted.

Additional research is needed to fully examine the reasons behind these differences as well as to identify appropriate interventions that promote sun protection, they added.

There was no external funding and the authors had no conflicts of interest to disclose.
