Individuals with a family history of colorectal cancer have a higher risk of developing colorectal cancer than the general population, and studies have shown that they are more likely to undergo colorectal cancer screening.
Dr Sapna Syngal and colleagues from Massachussetts, USA assessed the overall and race- and ethnicity-specific effects of a family history of colorectal cancer on screening.
The team analyzed data from the 2009 California Health Interview Survey to estimate overall and race- and ethnicity-specific odds ratios for the association between family history of colorectal cancer and screening.
The unweighted and weighted sample sizes were 23,837 and 8,851,003, respectively.
The research team found that individuals with a family history of colorectal cancer were more likely to participate in any form of screening, and in colonoscopy screening than those without a family history, but this association varied among racial and ethnic groups.
The magnitude of the association between family history and colonoscopy screening was highest among Asians, lowest among Hispanics, and comparable between non-Hispanic whites, and non-Hispanic blacks.
Dr Syngal's team concludes, "The effects of family history of colorectal cancer on participation in screening vary among racial and ethnic groups, and have the lowest effects on Hispanics, compared with other groups."
"Consequently, interventions to promote colorectal cancer screening among Hispanics with a family history should be considered."
