Public image and governance of epidemics: comparing HIV/AIDS and SARS.

A comparative analysis of the 2002-2003 infectious disease outbreak, severe acute respiratory syndrome (SARS), and the HIV/AIDS epidemic that has affected the world over the past two decades reveals the significant role of socio-cultural beliefs and attitudes in the shaping of people's lifestyles and approaches to the control and prevention of epidemics. The main research question is: what can we learn from the SARS experience about effective prevention of HIV/AIDS? The sources of data include population figures on the development of these epidemics and findings from two sociological studies of representative samples of Singapore's multi-ethnic population. The comparative study illustrates the impact of cultural beliefs and attitudes in shaping the public image of these two different infectious diseases; the relevance of public image of the disease for effective prevention and control of epidemics.

Crisis prevention and management during SARS outbreak, Singapore.

We discuss crisis prevention and management during the first 3 months of the severe acute respiratory syndrome (SARS) outbreak in Singapore. Four public health issues were considered: prevention measures, self-health evaluation, SARS knowledge, and appraisal of crisis management. We conducted telephone interviews with a representative sample of 1,201 adults, > or = 21 years of age. We found that sex, age, and attitude (anxiety and perception of open communication with authorities) were associated with practicing preventive measures. Analysis of Singapore's outbreak improves our understanding of the social dimensions of infectious disease outbreaks.

Traditional healing systems and the ethos of science.

This paper addresses the challenge posed to traditional Chinese medicine by the ethos of science and explores three related assumptions. First, the ethos of traditional Chinese medicine is incompatible with the ethos of science. Second, the challenge of science to traditional Chinese medicine is represented by the requirement to comply with internationally recognized standards of medical research and practice applied to biomedicine, adopted and implemented by the State. The State requires that the safety and effectiveness of traditional Chinese medicine procedures and medications be ascertained following the methodology chartered by the ethos of science. Third, traditional Chinese medicine practitioners present a third ethos, the "ethos of pragmatic healing" based on the pragmatic acculturation of clinical practice, as an alternative to the ethos of science. This third ethos is an inadequate response to the challenge because it increases the divergence between health care policy requirements of scientific scrutiny and the fostering of traditional Chinese medicine as an icon of Chinese culture. The study is based on data from personal interviews with representative samples of three ethnic populations in Singapore; secondary data from other studies; relevant official data; and documents from biomedical and traditional Chinese medicine organizations. The methods include inductive analysis, multiple correlation and regression, and factor analysis among others. The analysis indicates that the pressure to comply with official health regulations and the inability to succeed under the ethos of science lead traditional Chinese medicine practitioners to respond with an ethos of pragmatic healing that eschews conceptual analysis, ignores the paradigmatic divide with biomedicine, and focuses on "using what works". This third ethos can only be a temporary response to the pressure to upgrade the practice of traditional Chinese medicine and it does not correspond to pragmatic acculturation commonly found in the population. The ethos of pragmatic healing leaves the challenge of science unresolved and it is likely to increase the level of conflict between the realm of biomedicine (including health care policy requirements of scientific scrutiny) and the ethos of traditional Chinese medicine.

Food groups and the risk of colorectal carcinoma in an Asian population.

BACKGROUND: Singapore Chinese have experienced a rapid transition toward a pattern of disease in which lifestyle-related, chronic, degenerative diseases are major public health concerns. The rates of colorectal carcinoma have increased 2-fold over the last 3 decades. It has long been known that dietary factors play a role in the risk of this disease, although studies in Asian populations, with their unique dietary intake, have been few. METHODS: The authors conducted a population-based case-control study that included 121 Chinese patients with colorectal carcinoma and 222 healthy control participants who provided information on usual intake of major food groups in the preceding 3 years, physical activity, family history of colorectal carcinoma, and demographic variables through an in-person questionnaire. RESULTS: High intake of red meat, but not other meats, indicated a predisposition to risk of colorectal carcinoma (adjusted odds ratio [OR] for the highest tertile vs. the lowest tertile, 2.2; 95% confidence interval [95%CI], 1.1-4.2). A low vegetable intake also was associated with a higher risk, and the combined effect appeared to be additive. Those in the highest tertile of meat intake and the lowest quartile of vegetable intake had an OR of 2.6 (95%CI, 1.0-6.7). The authors observed a slight, albeit nonsignificant, positive association with foods high in refined sugars. There was no association observed with fruit or soy-legume intake in this study. Among nondietary variables, a family history of colorectal carcinoma conferred a significant increase in risk (OR, 6.7; 95% CI 2.4-18.7). CONCLUSIONS: Meat intake and vegetable intake were associated significantly with risk of colorectal carcinoma in this Asian population, and further studies on the effects of changes in these specific types of food may shed light on how best to reduce the rapid increase in rates in similar populations.
