A new CDC report estimating the lifetime risk of HIV diagnosis for several populations found great disparities by racial/ethnic groups, reports The Associated Press. Based on HIV surveillance, vital statistics, and census data from 37 states and Puerto Rico for 2007, an estimated 4.65 percent of blacks/African Americans would receive an HIV diagnosis during their lifetime, or 1 in 22, according to the new report.
The 1 in 22 risk was more than twice the estimated lifetime risk of HIV diagnosis for Hispanics/Latinos (1.92 percent, or 1 in 52) and eight times that of whites (0.59 percent, or 1 in 170), the report found.
The estimates of lifetime risk of HIV diagnosis are not representative of all HIV diagnoses in the United States. However, the data also were not considered unusual. A report published in 2008 found a similar high estimated lifetime risk of HIV diagnosis for blacks.
The new report, "Estimated Lifetime Risk for Diagnosis of HIV Infection Among Hispanics/Latinos - 37 States and Puerto Rico, 2007," was published in Morbidity and Mortality Weekly Report.
But, here's another alarming statistic: nearly one in five gay and bisexual men in 21 major U.S. cities are infected with HIV, and nearly half of them do not know it, U.S. health officials said in September.
Young men, and especially young black men, are least likely to know if
they are infected with HIV, according to a study by the U.S. Centers for
Disease Control and Prevention.
Researchers at the CDC studied
8,153 men who have sex with men in 21 U.S. cities. The men were taking
part in the 2008 National HIV Behavioral Surveillance System, which
looked at prevalence and awareness of the human immunodeficiency virus
or HIV, the virus that causes AIDS.
Overall, they found that 19
percent of gay men are infected with HIV. The study found that 28
percent of gay black men infected with HIV, compared with 18 percent of
Hispanic men and 16 percent of white men.
Black men in the study
were also least likely to be aware of their infection, with 59 percent
unaware of their infection compared with 46 percent of Hispanic men and
26 percent of white men.
Age also plays a role. Among 18 to
29-year-old men, 63-percent did not know they were infected with HIV,
compared with 37 percent of men aged 30 and older, the team reported in
the CDC's weekly report on death and disease.
The CDC recommends
that gay and bisexual men of all ages get an HIV test each year, and men
at highest risk -- those who have multiple sex partners or use drugs
during sex -- get tested every three to six months.
