Interactive effects of individual and neighborhood race and ethnicity on rates of high-grade cervical lesions
Menée dans le comté de New Haven (Etats-Unis) à partir de données médicales et socio-démographiques portant sur la période 2008-2011 (âge des femmes : 20 à 39 ans), cette étude analyse la relation entre l'appartenance ethnique, la composition ethnique du quartier de résidence, son niveau socio-économique et le taux de lésions cervicales de haut grade
We estimated the main and interactive effects of individual race/ethnicity (black, Hispanic, white) and area race, ethnicity, and poverty (proportions of the female population black, Hispanic, and living below the federal poverty level at the census tract level, respectively) on rates of high-grade cervical lesions among young women. Using data from a statewide surveillance system during 2008–2011, we found a marginally significant interaction (P < 0.05) between individual race/ethnicity and area race, with black and Hispanic women living in areas with ≥20% of the female population black having elevated rates compared to those living in areas with <20% of the female population black. These findings indicate a possible synergistic effect between individual race/ethnicity and racial composition in neighborhoods on precancerous cervical lesions.
