HealthDay News – Sociodemographic factors associated with the risk for a positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) test result include deprivation, population density, and ethnicity, according to a study published online May 15 in The Lancet Infectious Diseases.

Simon de Lusignan, MBBS, MD, from the University of Oxford in the United Kingdom, and colleagues analyzed data for patients in a primary care sentinel network who were tested for SARS-CoV-2 between January 28 and April 4, 2020. Of 3802 SARS-CoV-2 test results, 587 were positive.

The researchers found that male sex was independently associated with testing positive for SARS-CoV-2 (adjusted odds ratio [aOR], 1.55) in a multivariable analysis. Compared with children, adults were at increased risk for testing positive for SARS-CoV-2; in the multivariable model, adults aged 40 to 64 years were at highest risk (aOR, 5.36 versus children). The adjusted odds of a positive test were increased in black vs white people (aOR, 4.75). The likelihood of testing positive was also increased for those living in urban vs rural areas (aOR, 4.59) and in the most vs the least deprived areas (aOR, 2.03). People with chronic kidney disease were more likely to test positive (aOR, 1.91), as were those with obesity versus normal weight (aOR, 1.41). Active smoking was associated with a reduced risk for a positive test result (aOR, 0.49).
