Missing the HIV message (American Public Health Assn. annual meeting)

After decades, efforts toward AIDS prevention may seem tired and worn. But people are still getting sick, as new at-risk populations are being identified.

Although the HIV/AIDS epidemic is decades old and preventive measures have been widely promoted, another 40,000 people become infected each year. And, despite considerable progress in reducing the disease's impact among populations hardest hit initially -- gay men and intravenous drug users -- other populations, especially racial and ethnic minorities, continue to bear a disproportionate burden, according to a recent report from the Centers for Disease Control and Prevention.

That's why researchers are crafting prevention messages to reach these vulnerable people. Several presenters at the American Public Health Assn.'s 135th annual meeting, held Nov. 3-7 in Washington, D.C., provided examples of effective programs.

Some researchers zeroed in on young minority students at colleges and universities, a group not traditionally thought of as at high risk for contracting the AIDS virus.

Young, female, Hispanic college students were the focus of research done at Florida International University in Miami. Hispanic women ages 16 to 24 are one of the fastest-growing groups for getting HIV infection, said Robert Malow, PhD, professor of public health and director of FIU's AIDS Prevention Project.

These women, who may have been born in Latin American nations such as Cuba, Panama, Honduras, Guatemala and Columbia, are often caught in a cultural crunch. While focusing on the importance of remaining virgins for marriage, they are also intent upon not chasing men away. They may practice oral and anal sex in order to maintain their virginity, but are unaware of the HIV risks those options involve, he said.

The need to educate this often-sheltered population led to the formation of the university's peer education program, SENORITAS -- Student Education Needed in Order to Reduce Infection and Transmission of AIDS/HIV and STIs.

Spreading the word

The situation is similar for African-American college students, noted CDC medical epidemiologist Madeline Sutton, MD, MPH. She led surveys on student attitudes and behaviors about HIV and AIDS and found a difference between perceived and actual risk.

Of 1,172 students surveyed at historically black colleges and universities, 79% said they were at low risk for acquiring the virus, but only 55% had used condoms during their last sexual encounter. In addition, many of the students, both males and females, reported encounters with multiple partners during the previous 12 months.

40,000 people become infected with HIV each year.

On the plus side, many said they would be willing to have an HIV test. And those who said they already had been tested said they had done so after a talk with a doctor or other health professional, said Dr. Sutton. She urged physicians to take advantage of their persuasive powers. "Students take it to heart when we sit down and discuss with them getting an HIV test."

Physicians and other health professionals were also found to be believers in packaging the prevention message with medical care, according to a survey sent to 136 physicians, nurse practitioners and physician assistants by the AIDS Activities Coordinating Office in Philadelphia.

The surveyors thought physicians and others might be too time-strapped by patient care to think about prevention, said Marlene Matosky, MPH, RN, a member of the research team. But that wasn't the case.

Although nearly everyone who responded thought prevention was important, almost half said they would like to be more effective at communicating the message to patients. The physicians particularly needed materials to distribute to those already infected. As a result, the city is now gearing up to supply such handouts as well as information on bleach kits to use when cleaning needles, needle-exchange programs and condom distribution sites, Matosky said.

Another session focused on reaching Hispanic men who have sex with men. These men do not necessarily consider themselves to be gay and so are often missed by the messages that began going out to that group decades ago, said Ana Martinez-Donate, PhD, assistant professor of health promotion and behavioral sciences at San Diego State University's Graduate School of Public Health.

She led a research team in a campaign called Hombres Sanos, or "healthy men." It promotes condom use and HIV testing among this high-risk group. Researchers distributed materials at nightspots and barbershops and aired radio promos. The effort has produced good results, she said. Condom use increased, as did the men's perception of their risk.

How AIDS is spreading

Adolescent girls and young adult women have been identified as being at high risk for HIV infection. From 2001 to 2005, the majority of AIDS cases diagnosed among these groups were attributed to high-risk heterosexual contact.

Injection drug use333800
High-risk heterosexual contact2,0864,740

Disproportionate burden

Hispanics made up about 14% of the U.S. population in 2005, but accounted for 19% of the AIDS cases reported to the CDC that year. Similarly, blacks made up about 13% of the U.S. population but 40% of total AIDS cases. Of the 956,019 AIDS cases reported to the CDC through 2005, the disease burden for these two ethnic groups breaks out as follows:

HispanicsBlacks
Total cases19%40%
Women with AIDS19%60%
Heterosexual people at high risk22%59%
Children younger than 1323%59%
Adults and adolescents*20%48%

CDC, states at odds on HIV testing

State laws often stand in the way of implementing a 2006 Centers for Disease Control and Prevention recommendation to offer HIV testing routinely to most patients, said a study presented at the APHA's annual meeting last month.

Many state laws require specific consent for an HIV test rather than the CDC-recommended "opt out" procedure in which a physician notifies patients that HIV testing will be conducted and offers them an opportunity to decline. Pre- and posttest counseling also is required by many states.

Robert Wood Johnson Foundation clinical scholar and researcher Anish Mahajan, MD, MPH, and others found that 22 states have laws that are incompatible with the federal outline.

Their search of state health department Web sites also found that few provide guidance about the CDC approach. "Our contention is that proper and responsible implementation of the recommendations will depend on providers being well informed and well educated on how best to ensure patient autonomy, and how best to recognize when a patient really needs a referral to counseling and getting them there," Dr. Mahajan said.

A separate presentation detailed how the California Medical Assn. and state AIDS advocacy groups worked together to change that state's law to facilitate routine screening in all health care settings. The bill, signed into law in October, simplifies the consent necessary for the test. It takes effect Jan. 1.

Rebuilding a Gulf Coast health care system

The health care infrastructure that was demolished in the aftermath of the hurricanes and floods that hit the Gulf Coast in 2005 is being rebuilt. And the plan now in the works could produce a very different system from what existed before.

Reports of recovery efforts were shared during the American Public Health Assn.'s 135th annual meeting held Nov. 3-7 in Washington, D.C.

A Louisiana blueprint calls for a system of local facilities to provide primary and preventive care. Its goal would be to keep people out of hospitals. "We knew we needed to take the opportunity and build something that was more resilient," said Karen DeSalvo, MD, MPH, associate professor of medicine at Tulane University in New Orleans.

No one wants to replicate what was there before, she said. Health care in Louisiana had been costly and was not always good quality. And health outcomes were not optimal. "Who would want to go back to that?" Dr. DeSalvo asked.

The new approach would create a safety net to replace the state public hospital system and would provide each patient with a convenient medical home. The system would be supported by state-of-the-art health information technology, for which Louisiana has set aside $50 million.

New Orleans has made some strides already in returning to normal with about 80% of the population and 80% of the physicians back. Eleven hospitals are open.

Erin Brewer, MD, MPH, director of the city's Center for Community Health, said public health units also are opening, and a rebuilt newborn screening lab should be operational soon. Until now, Iowa's public health department had been providing screening help.

But there is no clear measure of recovery when it comes to people, noted David Abramson, PhD, MPH, director of research at Columbia University's National Center for Disaster Preparedness in New York City. He led a 1,244 household study of the health and social consequences of the storms on the people who were, for the most part, driven from their homes.

Health data for children show a huge increase in depression and anxiety, he said. Asthma rates have increased, and care for children with chronic conditions is lacking. Data also suggest a divide in which those with access to resources are more likely to rebuild than those without, he added.

The accelerating disappearance of temporary trailer parks is viewed as promising. But whether returning families are connecting with social services, schools and medical care is still an open question, Dr. Abramson said.

Gulf Coast burnout

The adrenaline that kept health care workers on the go in the first year after hurricanes and floods devastated the Gulf Coast waned by the second year, and burnout was common, said physicians there.

The drop in spirits was caused in part by patients' many nonmedical concerns, said Karen DeSalvo, MD, MPH, associate professor of medicine at Tulane University in New Orleans. People had nowhere to live and no jobs.

"We aren't equipped to deal with that," she said, adding that the medical staff had to accept that there was only so much they could do.

Every staff member "was made to go to a therapist." The process was not only good at lowering anxiety levels, but it also helped in understanding patients' mental health status, Dr. DeSalvo said.

College-age drinking; tobacco-related mortality; mental health services and teens

Research presented at the American Public Health Assn.'s annual meeting last month in Washington, D.C., covered a broad range of topics that included alcohol and tobacco use and mental health.

Researchers from Wake Forest University School of Medicine reported on a new college drinking phenomenon -- mixing caffeinated energy drinks with alcohol. Students say this mixture lets them consume more alcohol without -- at least in their minds -- appearing intoxicated. The researchers found, though, that those who engaged in the practice were at increased risk for alcohol-related health consequences.

Findings were based on a survey of 4,271 college students from 10 North Carolina universities. Of those queried, 697 reported drinking such mixtures in the previous 30 days.

In another presentation, researchers offered evidence that increases in tobacco taxes, smoking bans and other such controls may be helping to reduce cancer deaths, at least among those studied -- African-Americans living in New York City.

An analysis found that tobacco control measures adopted by the city were mirrored by a drop in the cancer death rate for this group. By 2003, New York City African-American cancer death rates had dropped since 1981 to below levels for whites in every state except Utah and Hawaii, reported Bruce N. Leistikow, MD, associate professor of public health at the University of California, Davis.

Meanwhile, a study conducted by researchers from Columbia University in New York City found that fewer minority adolescents who are suicidal seek mental health services than do white teens. These findings were based on the responses to a national survey of 12- to 17-year-olds.

The largest gap was seen in outpatient care. While 29% of white youth used such services, the number dipped to 13% among blacks. Overall, 50% of white teens reported receiving services for emotional or behavioral problems. The number fell to 37% for Hispanic teens and 31% for black teens. The gap narrowed in the use of school-based services.

Lastly, a presentation by Evan Kanter, MD, PhD, a staff psychiatrist at the VA Puget Sound Health Care System in Seattle, sought to quantify the high levels of mental health concerns among soldiers returning from conflicts in Iraq and Afghanistan. Dr. Kanter reported that posttraumatic stress disorder is the most common mental health disorder currently being diagnosed within this population. Specifically, an estimated 12% to 20% of returning veterans from Iraq, or as many as 300,000 soldiers, are expected to have PTSD, he said, noting that the figure could go higher.
