The public's problem with public health research

Public health research is divided into factions which are oftenengaged in bitter theoretical and methodological disputes, especiallywhen issues of funding are discussed. From the perspective ofa user of health services, these rivalries are an obstacle topublic health. This paper explores three approaches to understandingthe foundations of these differences. The first is a discussionof disciplinary sub-cultures, the second a brief discussionof a philosophy of knowledge and the third a social perspectiveon paradigms. The unifying theme is the idea of disciplinarysub-cultures.     

The problem of "significant risk": exploring the public health impact of criminalizing HIV non-disclosure

Using criminal law powers to respond to people living with HIV (PHAs) who expose sexual partners to HIV or transmit the virus to them is a prominent global HIV public policy issue. While there are widespread concerns about the public health impact of HIV-related criminalization, the social science literature on the topic is limited. This article responds to that gap in knowledge by reporting on the results of qualitative research conducted with service providers and PHAs in Canada. The article draws on a studies in the social organization of knowledge perspective and insights from critical criminology and work on the "medico-legal borderland." It investigates the role played by the legal concept of "significant risk" in coordinating criminal law governance and its interface with public health and HIV prevention. In doing so, the article emphasizes that exploring the public health impact of criminalization must move past the criminal law--PHA dyad to address broader social and institutional processes relevant to HIV prevention. Drawing on individual and focus group interviews, this article explores how criminal law governance shapes the activities of providers engaged in HIV prevention counseling, conceptualized as a complex of activities linking clinicians, public health officials, front-line counselors, PHAs, and others. It emphasizes three key findings: (1) the concept of significant risk poses serious problems to risk communication in HIV counseling and contributes to contradictory advice about disclosure obligations; (2) criminalization discourages PHAs' openness about HIV non-disclosure in counseling relationships; and (3) the recontextualization of public health interpretations of significant risk in criminal proceedings can intensify criminalization.     

Nutritional anaemia--a major controllable public health problem.

Nutritional anaemia, due chiefly to iron deficiency, is widely prevalent in many parts of the world. There is increasing evidence that even mild anaemia affects health and reduces productivity and that a high prevalence of anaemia has profound socioeconomic consequences. The pathogenesis of nutritional anaemia is now reasonably well understood. Measures avilable for combating it include: therapeutic supplementation for accessible population groups with a high prevalence of anaemia, such as pregnant women and schoolchildren; iron fortification of one or more widely consumed foodstuffs; management of those conditions, such as hookworm infestation, that increase requirements for haemopoietic nutrients; and education of the public, and of all categories of health personnel, regarding the importance of anaemia and the ways of controlling it. Experience has shown that there is no simple solution to the problem and in each area where iron deficiency anaemia is prevalent it will probably be necessary to develop and combine many or all of these measures. In each community it will be necessary to introduce these measures so that their effectiveness can first be studied in a pilot trial. When this has been successfully completed it should be followed by a field trial under realistic conditions, and only when this has proved successful should a regional or national programme be introduced. However, the problem is complex and it is only by sustained effort of all concerned that it will prove possible to develop adequate public health control of nutritional anaemia.
