Declining prevalence of HIV-1 infection in young Thai men.
ABSTRACT To evaluate trends in HIV-1 seroprevalence in Thailand.
HIV-1 serosurvey of successive cohorts of young Thai men entering service with the Royal Thai Army (RTA) between November 1989 and November 1994.
In November 1989, the RTA Medical Department began routine HIV-1-antibody screening of men who were selected by lottery for conscription. Between November 1989 and November 1994, 311,108 young men were screened at induction. Demographic data were collected between November 1991 and May 1993 and again in November 1994.
The seroprevalence of HIV-1 among conscripts nationwide increased rapidly from 0.5% in 1989 to 3.5% in 1992 and reached 3.7% in 1993. In 1994, the overall prevalence decreased to 3.0%. The decrease was greatest in the upper North (from 12.4% in 1992 to 7.9% in 1994), where the prevalence has been the highest. However, decreases were observed in men from all regions of residence in the country, from both rural and urban areas, and at all educational levels.
The decline in prevalence suggests declining incidence and that HIV control programs in Thailand are having an impact on the HIV epidemic.

ABSTRACT: We systematically examine community reaction to persons living with HIV/AIDS (PHAs) and their older parents in Thailand. We focus on parents as well as PHAs because parents are major providers of care for their ill adult children. Our analyses are based on several sources of recently collected survey and qualitative data from a wide range of perspectives. We find important variations in community reaction to PHAs and their families, but overall these reactions are much more positive than is widely assumed. We conclude that much existing research on community reaction to AIDS neglects both a rich body of social theory on stigma and a strong tradition of population-based empirical research in sociology. Much existing research also fails to adequately distinguish between key aspects of the social settings where most AIDS cases occur and the social settings where most of the stereotypes surrounding AIDS-related stigma have originated. A closer marriage between empirical and theoretical approaches to social stigma is required to advance our understanding of this critically important dimension of the AIDS epidemic.Journal of Health and Social Behavior 01/2006; 46(4):392-410.

- "However it is also important to assess what else happened in line with trends in biological markers, HIV/AIDS and STDs (Figures 3a, 3b, 3c). HIV prevalence in Thailand increased rapidly in the late 1980s in surveillance data in quick succession among drug users, sex workers, army recruits, and pregnant women (showing the practical problems of targeting HIV prevention first to risk groups suggested by STD prevention) (Brown et al. 1994; Mason et al. 1995; Rojanapithayakorn & Hanenberg, 1996). Early HIV, AIDS and behavioural surveillance was central to the response, providing information politically and publicly. "
ABSTRACT: The clearest example of declines in HIV prevalence and changes in sexual behaviour comes from Uganda. Are there lessons to learn for other countries or is Uganda unique? In this paper, we assess the epidemiological and behavioural data on Uganda comparatively to other African countries and then analyse data from other populations where HIV has declined. In Uganda, HIV prevalence declined from 21% to 9.8% from 1991–1998, there was a reduction in non-regular sexual partners by 65% and greater levels of communication about AIDS and people with AIDS through social networks, unlike the comparison countries. There is evidence of a basic population level response initiated at community level, to avoid risk, reduce risk behaviours and care for people with AIDS. The basic elements—a continuum of communication, behaviour change and care—were integrated at community level. They were also strongly supported by distinctive Ugandan policies from the 1980s. We identify a similar, early behaviour and communication response in other situations where HIV has declined: Thailand, Zambia and the US Gay community. In Thailand, visits to sex workers decreased by 55% and non-regular partners declined from 28% to 15% (1990–1993): as important as the ‘100% condom use policy’. Similarly, in Zambia and Ethiopia risk behaviour has decreased and analysis of Sexually Transmitted Disease (STD) rates among Gay populations in the USA shows a decline from as early as 1985 in White Gay populations, with later declines in Hispanic and Black Gay populations. These responses preceded and exceeded HIV prevention. However, where they were built on by distinctive HIV policies, HIV prevention has been scaled and led to national level declines in HIV. It is not easy to transfer the lessons of these successes. They require real social and political capital in addition to financial capital. Nevertheless, similar characteristics are present in community responses in Africa, Asia and USA, and even in fragmented signs of HIV declines in other African cities. Only in a few situations has this behaviour and communication process been recognised, mobilised and built on by HIV prevention policy. Where this has occurred, HIV prevention success has been greater than biomedical approaches or methods introduced from outside. It represents a social vaccine for HIV from Africa, and is available now.African Journal of AIDS Research 01/2003; 2(1):9-21. DOI:10.2989/16085906.2003.9626555

ABSTRACT: To assess whether educational status is associated with HIV-1 infection in developing countries by conducting a systematic review of published literature. Articles were identified through electronic databases and hand searching key journals. Studies containing appropriately analysed individual level data on the association between educational attainment and HIV-1 status in general population groups were included. Twenty-seven articles with appropriately analysed results from general population groups in developing countries were identified, providing information on only six countries. Large studies in four areas in Africa showed an increased risk of HIV-1 infection among the more educated, whilst among 21-year-old Thai army conscripts, longer duration of schooling was strongly protective against HIV infection. The association between education and schooling in Africa was stronger in rural areas and in older cohorts, but was similar in men and women. Serial prevalence studies showed little change in the association between schooling and HIV over time in Tanzania, but greater decreases in HIV prevalence among the more educated in Uganda, Zambia and Thailand. In Africa, higher educational attainment is often associated with a greater risk of HIV infection. However, the pattern of new HIV infections may be changing towards a greater burden among less educated groups. In Thailand those with more schooling remain at lower risk of HIV infection.Tropical Medicine & International Health 07/2002; 7(6):489-98. DOI:10.1046/j.1365-3156.2002.00889.x
