National Minority Health Month: Child Asthma

According to the CDC, 7 million children suffer from asthma nationwide. According to the New York City Department of Health and Mental Hygiene, children in New York City were almost twice as likely to be hospitalized for asthma as children in the United States as a whole. Even more alarming, in recent years, the Bronx has been the New York City borough with the highest overall rates of asthma hospitalizations, deaths and prevalence among children as well as adults. Clearly, disparities exist.

Asthma is a chronic lung disease that can cause the airways to become inflamed and narrow. This can result in coughing, wheezing and tightness of the chest which may make it difficult to breathe. Asthma attacks are often triggered by illness, strenuous activity and the environment; smoke, allergies, pets, mold, dust and pollution can be a trigger. Cockroaches can also trigger asthma attacks, as many children are allergic to the material associated with decaying roaches, and live roaches' excrement. Partners Healthcare, a team of doctors, nurses, respiratory therapists and other health care professionals, cites cockroaches as a bigger trigger than pet dander and dust. Though asthma cannot be cured, it can be treated with regular long-acting medications, and fast-acting medications in the event of an attack.

Children with asthma tend to have family members with asthma, implying that the condition is inherited. However, it is difficult to establish a link between inheritance and an entire race because race is a social construct that cannot be clearly defined by genetics. Asthma can be inherited by any child, regardless of their ethnic background, depending on the child's family history. However, asthma affects children from ethnic minority groups at disparate rates. For example, non-Hispanic black children have a higher prevalence of asthma and die at higher rates from asthma than non-Hispanic white children. Hispanic children have a higher prevalence of asthma compared to non-Hispanic white children.

Many ethnic minority children tend to live in areas in which smoke, mold, dust, pollution and roach infestation may be a problem. These triggers can greatly exacerbate asthma. Due to a lack of health insurance or a regular primary care physician, minority children suffering from asthma may be forced to use a hospital's emergency department for care. Also, due to lack of insurance and/or family instability, it may be difficult for children to regularly take required long-acting asthma medication, as prescribed. One study actually examined the degree to which instability within a family can negatively impact a child's health. Investigators found that family instability is related to poor child health, including asthma.

Additionally, cultural boundaries may contribute to disparities if they result in poor communication between the physician and patient or sub-par care. Poorly controlled asthma has also been linked to poorer performance in school (for example, more absenteeism), and may even help explain the academic achievement gap that exists among children from different ethnic groups. The aforementioned factors contribute to health disparities but are really symptoms of much greater social injustices. In order to rectify the problem, we must more closely examine our society.

National Minority Health Month: HPV and Cervical Cancer

At the American Association for Cancer Research (AACR) annual meeting on April 1, researchers said that the human papillomavirus (HPV) lasts longer in African-American women than in their white counterparts. This may shed light on some of the disparities that exist among women from different ethnic groups regarding HPV and cervical cancer.

HPV is a virus that is contracted through sexual contact. According to the Center for Disease Control and Prevention (CDC), there are over 40 types of HPV that can infect the genital area, throat and mouth. Condoms lower the risk of transmitting the virus, but areas not covered by condoms can still become infected. The CDC estimates that 20 million Americans are currently infected with HPV.

In addition to causing genital warts, another major health problem that results from HPV is cervical cancer and other genital cancers. Cancer and warts result from the body's inability to return the infected cells back to normal. In addition to the use of condoms, a vaccine (i.e. Gardasil) can lower your risk of developing warts and/or cancer. Gardasil protects against 4 types of HPV. Condoms should still be used because other types of HPV exist, and to protect against other sexually transmitted infections. Gardasil is recommended for girls and boys ages 9-26. Prevention means working to stop something before it occurs. Even if an individual has not yet had her first sexual contact, she should still be vaccinated.

In recognition of National Minority Health Month, it is important to outline the disparities associated with HPV and cervical cancer among women. While the incidence of cervical cancer among non-Hispanic white women was 8.5 in 100,000 women, the incidence was 13.8 and 11.4 for Hispanic and African-American women respectively. Despite the fact that Asians and Native Americans and Alaskins had a lower incidence of cervical cancer than their white counterparts, these minority groups were more likely to die from cervical cancer; Hispanics and African-Americans were more likely to die as well.These disparities may stem from several issues. Regardless of race, uninsured women are less likely to have regular PAP smears, and thus may not learn they have cervical cancer until it is advanced. However, it is also true that many uninsured women happen to come from low socioeconomic backgrounds and/or are from ethnic minority groups. Health and Human Services (HHS) said in a report that in 2005 many uninsured people were just above, at or well below the poverty line. The same HHS report said that Hispanics are disproportionately uninsured as they represent 14% of the general population but 30% of the uninsured population. As a group, Hispanics, African Americans, American Indians and Asians/Pacfiic Islanders constituted 52% of the uninsured population.

Many cases of cervical cancer are related to HPV. Many minority groups are not well-educated about how HPV is contracted, spread and treated. This may relate to the level of access to general education and health care. Even among minority women that are educated and have access to regular health care, cultural attitudes toward Western medicine and the health care system may contribute to these disparities. These same factors can also influence whether or not a woman chooses to be vaccinated for HPV. Lower vaccination rates can lead to an increased risk for contracting HPV, and the development of cervical cancer.

The study presented at the AACR annual meeting found a biological factor that may also contribute to disparities related to HPV. The investigators found that African-American women hold on to HPV longer in the body than their white counterparts; this may be a reflection of their genes and immune systems. Kim Creek, vice-chair and professor of pharmaceutical and biomedical sciences at South Carolina College of Pharmacy said, " [the] body recognizes it [HPV] as a viral infection and usually clears the virus within one or two years...It is those women who have difficulty clearing it that are at higher risk of cervical disease and cervical cancer." This recent finding may help explain the higher prevalence of cervical cancer among African-Americans. It would be interesting to study whether other minority groups disparately affected by HPV and cervical cancer, also hold on to the HPV virus longer than their white counterparts.

In summary, access to health insurance, education, health care, cultural attitudes and genetics are all factors that contribute to health disparities related to HPV and cervical cancer. It is clear that this is a complex problem. Cultural competency within the health care system, and initiatives that target high-risk populations will help us make great strides toward the elimination of health disparities.
