Prevention Mother to Child HIV transmission

            The “AIDS epidemic” may be one of the most widely recognized and globally concerning health issues to date. Contrary to its centrality in world health forums and non-profit organizations today, being a key target of scrutiny for the World Health Organization (WHO) and UNAIDS, a subgroup of the United Nations focused on HIV/AIDS, the acquired immunodeficiency syndrome, which we call “AIDS”, has only been named and known as a disease for close to thirty years. In the United States, the first records of clinical observance of the disease occurred in 1981 among populations of drug-injecting users and homosexual men. During that time of limited knowledge, doctors were forced to make logical assumptions based on early cases and what was most probable. Thus, the earliest AIDS patients were diagnosed with “GRID”, an acronym for gay-related immune deficiency, because of the belief that the disease was associated with the gay community.
Ever since its discovery, medical efforts in order to battle AIDS have persisted consistently, resulting in countless research hours and some successful advances. Consequentially, medical knowledge has expanded immensely within the last few decades. Human immunodeficiency virus (HIV) is understood to be the root cause of AIDS by slowly attacking white blood cells in the human immune system resulting in the ultimate inability of the body to fight previously harmless pathogens. The virus progresses in stages: a flu-like infection, an asymptomatic period, and finally acquired immunodeficiency syndrome (AIDS), in which the low blood count makes the individual especially susceptible to infections.  Transmission is through the exchange of bodily fluids most commonly via unprotected sexual intercourse or contaminated needles. Currently, no cure or vaccine exists. The most effective prevention methods, safe sex and clean needles, are strongly emphasized. Beyond prevention, the WHO also focuses on global availability of treatment. Antiretroviral therapy coverage among people with advanced HIV infection was one of WHO’s indicator for one of its 2012 millennium development goals (WHO page 26). Many other goals exist, including elimination of new HIV infections among children, prevention of HIV among drug users, reduction of sexual transmission, etc.
WHO’s 2012 Report lists ten categories of “global health indicators”, each quantitatively analyzed through various statistics. “Health service coverage indicators reflect the extent to which people in need actually receive important health interventions,” one indicator being, “pregnant women with HIV receiving antiretrovirals to prevent mother to child transmission” (WHO page 96). This shows that the WHO acknowledges the importance of preventing HIV/AIDS from HIV-positive women via mother to child transmission (MTCT).
MTCT can occur during pregnancy, labor, delivery, or breastfeeding, so transmission can be prevented in various ways. According to the WHO website: “In the absence of any interventions transmission rates range from 15-45%. This rate can be reduced to levels below 5% with effective interventions.” Prevention of mother to child transmission (PMTCT) through counseling on infant feeding is the subject of the article Breast or Bottle? HIV-Positive Women’s Responses to Global Health Policy on Infant Feeding in India, written by Cecilia Van Hollen, an anthropology professor at Syracuse University. The article presents an ethnographic study of HIV positive woman living in Tamil Nadu, India concentrating on their experiences with maternal counseling, responses to the seemingly constantly-changing guidelines set by WHO and UNICEF, and a study of the complex decision making process of selecting breastfeeding or bottle-feeding. Interviews suggest that decisions were based on availability and affordability, but more importantly cultural values, perceptions, history. This study also suggests that sociocultural values are dynamic and can shift depending on global health initiatives.
Hollen does an excellent job of viewing the problem from a holistic perspective. She is clearly knowledgeable in Indian culture since she is able to make connections with women’s reasoning and Indian perspectives of female power and motherhood. Through the thoroughness of her study, I was able to recognize the importance of sociocultural beliefs for understanding the thought processes of these Indian women. Coherent to our class teachings, this situation clearly demonstrates how cultural perceptions and social representations overlap between medical anthropology and global health. Hollen’s anthropological approach to HIV/AIDS prevention provides insight on the shortcomings of the present systems in practice.
Before further discussion of the article, it is important to gain overview the history of AIDS/HIV. In accordance with the disease’s identification followed an incredible amount of social stigma. Initially, the lack of understanding surrounding transmission, treatment, and prevention ignited reactions, from the public and even within the healthcare community, of anxiety towards AIDS sufferers. The community response was probably heightened by the grave health risk posed in conjunction with the disease’s untreatable aspect. Adding to the fear was the fact that early victims of the diseases experienced painful deaths from rare complications. A great deal of negativity sprouted from the disease’s “GRID” origin and the fallacious belief that the disease selectively affected homosexuals.
Numerous records from 1980’s onward indicate discrimination against people with AIDS, which include many cases of social rejection and violence. Even after proven to affect broader populations, including children and heterosexual people, HIV/AIDS-related stigma has continued and resulted in social discrimination, ostracism, fear, and hate. Having the disease is often associated with negative assumptions of one’s behaviors regarding promiscuity, prostitution, drug use, etc. Although later information has specified the virus’s route of transmission, public fear has persisted, even causing self-stigmatization by people living with the disease.
            The Global Health Watch 3 does not address the stigmas of AIDS specifically, but notes that social factors play a role in maternal mortality, gender inequality, and mental health. The existence of “cultural and stigmatized notions of sexuality and morality” is attributed to numerous factors, some which are, “discrimination on the grounds of gender, race, ethnicity, religion, caste, and social factors such as lack of education and employment opportunities, increased workload, and political and legal issues” (Global Health Watch 3, page 125). Gender biases lead to “barriers in emergency care, poor referral practices, gaps in continuity of care, and improper demands for payment as a condition for delivery of health services,” for women in India. (Global Health Watch 3, page 125) The combination of these multiple social factors play a significant role in the uncomfortably high maternal mortality statistic of 500,000 women per year. Undoubtedly, a combination of these factors affects the target population in the article, Breast or Bottle?…, as well. First of all as women of Indian culture, they are already subject to minimal socioeconomic status and individual autonomy; thus as HIV-positive positive women, they are prime victims to the stigmas surrounding sexuality and morality.
The reason that I found it necessary to include extensive background information is because in order to fully comprehend current AIDS-related health issues, an understanding of its history is required. Since its origin, AIDS has been complexly intertwined between a health condition and mark of social judgment. Society reasoned that AIDS was a punishment for deviancy, a violation of social norms, thus discrimination was justified. Thus, people suffering from the disease are often shameful and secretive. Prevention or treatment of aids is stunted by people’s reluctance to be tested or seek out medical help. Fortunately, the adverse effects of society’s predispositions are widely recognized and targeted as problems in need ot immediate resolution. The theme of World AIDS Day 2012 hosted by World Health Organization was: Getting to Zero: Zero new HIV infections. Zero deaths from AIDS-related illness. Zero discrimination. It is important to note that alongside the goal for eradication of the disease is the elimination of discrimination, suggesting it is an equally important factor.
Thus returning to the article, Breast or Bottle?, HIV-positive mothers interviewed in the article were receiving counseling because of WHO’s efforts to prevent mother to child transmission (PMTCT). Several options of infant-feeding are available, each with different success rates.
“…Using the ‘full package’ of PMTCT interventions (antiretroviral treatments, cesarean section and replacement feeding) in industrialized countries have been able to reduce the rates of transmission to less than 2 percent. The risk of HIV infection through exclusive breastfeeding…is approximately 4 percent. However, the possibility of morbidity because of malnutrition, dehydration, or infection from improper use of replacement feeding may exceed 4 percent. And the risk of HIV transmission with mixed breastfeeding and alternative feeding is higher than exclusive breast feeding” (Hollen page 500).
Although the “full package” is the most successful prevention method, it is not economically available for all women, in addition to posing a risk of malnutrition. The distinction between versus bottle-feeding in determining the superior prevention method is highly dependent on each mother’s situation. Because the risks and benefits of each option don’t point to a clear solution, WHO and UNICEF implemented a system where counselors are faced with subjective decision of determining eligibility for replacement feeding using the AFASS criteria, which stands for Affordability, Feasibility, Acceptability, Sustainability, and Safety. If a woman meets the AFASS criteria, a counselor may recommend replacement feeding if guidance is sought.
Hollen mentions two major problems that exist with this system. First, the guidance counselor is supposed to provide the proper information in order to allow women to make informed decisions themselves. However, in practice, the counselor almost always steers their client in one direction or another. Mothers are much less given a choice, but told what to do. In just one of many examples, the counselor is found dictating the decision for the mother. Hollen writes, “a counselor working in one government hospital with a PPTCT program told me that, ‘we tell them not to breastfeed; to only give bottled milk’” (Hollen 503). Here issue lies in the fact that replacement feeding is expensive and when directed, women are forced to make incredible sacrifices. Even for women meeting the AFASS criteria, sustainability is a challenge and often women dilute the formula in order to extend its use, thus unknowingly restricting a child’s nutrition and potentially harming his/her growth and health. Lack of finances could possibly lead to inconsistent feeding methods, which could be harmful for HIV transmission.
The second problem concerns the lack of feasibility of the AFASS assessment. Most often the counselors consult HIV-positive mothers once in a hospital setting in order to determine their socioeconomic standing. Hollen suggests that current assessment practices are inadequate. “In principle the AFASS approach is laudable, but can a counselor really assess all of the AFASS criteria in the context of a very brief, decontextualized counseling session in a hospital? My research suggests not.” (Hollen page 515) The criteria itself is creditable, but because AFASS is not a simple checklist, yet an intricate measurement involving multiple factors, counselors are probably unable to make a correct evaluation in one brief sitting.
A culmination of these problems has revealed an instance where two women in seemingly identical situations were counseled in opposing directions. The counselors stated that the difference was that one woman was receiving financial/emotional support from a local NGO, “whereas the other woman was not affiliated with any such organization and, therefore, her family would not be able to overcome the social stigma that she would face from community members if she did not breastfeed.” (Hollen page 503) Despite the AFASS criteria, the end-deciding factor was sustainability via external support and the counselor explicitly directed the women. Interestingly, the counselor recognizes the critical impact of social stigmas, which is in agreement with Global Health Watch 3. 
An often-overlooked, but highly influential factor is the powerful cultural norm of breastfeeding. Many women are inclined to breastfeed because it is a symbol of maternal love, a fulfillment of a woman’s duty, and the transfer of “ethirppu sakti”, meaning immune power. Paralleling this is the notion of shame when a woman diverges from these norms, which is evident in Indian society. A woman not breastfeeding could be subject to high communal scrutiny and judgment. Because of the stigmas surrounding HIV/AIDS, a majority of the women who bottle-fed gave secondary rationales to curious community members. “To avoid public stigma, women therefore have developed creative, culturally informed rationales to avoid the critiques and also to avoid disclosure of their HIV status and the stigma and discrimination that may ensue” (Hollen page 509). Dealing with the negativity may truly be unbearable for some women, thus becoming a key determinant in their decision to breast or bottle-feed.
Important as it is, the cultural perspective of breastfeeding is not explicitly included in the AFASS criteria. Therein lies the key difference between the medical anthropology perspective compared to the approach by the WHO and UNICEF. An anthropological perspective would focus on the sociocultural values engrained within Indian society and the effect of social stigmas. This perspective would focus on societal factors and women’s response to them. It would also study the fluidity of perceptions and how they are affected by global health initiatives. The approach by the WHO and UNICEF is the one in place today, which accounts for mainly affordability and sustainability. The assessment will be more qualitative rather than quantitative.
I agree with Hollen that the AFASS assessment in practice is underdetermining. Conceptually, it would be ideal to have an anthropologist assessing each HIV-positive woman’s mental health and socioeconomic status in order to assess which prevention method will be most ideal. The benefit of having an anthropologist is that he/she will account for current and shifting cultural perceptions in the assessment. This will allow a more inclusive understanding between the counselor and the counseled, increasing communication, therefore having better results. Actually, the most ideal situation would be if funding were available in order to provide the “full package” of PMTCT free of charge to the mother. By being free, the concerns of affordability and sustainability are resolved.
Unfortunately, it is not practical since that would require tremendous funding.
A practical perspective could possibly suggest a more extensive AFASS assessment that encompasses multiple visits and an emotional/social/cultural component of consideration. This perspective is practical because it utilizes the current system in place, but improves it in a realistic way. A possible challenge could be the subjectivity of assessing an individual’s emotional/social/cultural being. Researchers could possibly find certain indicators that may be easier to assess.
            In conclusion, in this essay I have discussed the history and current HIV/AIDS related health problems from an anthropological perspective. HIV/AIDS is a concrete example of a global health problem that entails much more than the “disease” aspect of it. In order to understand AIDS, it is necessary to recognize how it is socially constructed as a “sickness” and the personal “illness” experience. By approaching the problem through a medical anthropological perspective, I was able to recognize often-overlooked characteristics and gain a better understanding of how to proceed in a global health perspective.
