Occupation and breast cancer: a Canadian case-control study.

A local collaborative process was launched in Windsor, Ontario, Canada to explore the role of occupation as a risk factor for cancer. An initial hypothesis-generating study found an increased risk for breast cancer among women aged 55 years or younger who had ever worked in farming. On the basis of this result, a 2-year case-control study was undertaken to evaluate the lifetime occupational histories of women with breast cancer. The results indicate that women with breast cancer were nearly three times more likely to have worked in agriculture when compared to the controls (OR = 2.80 [95% CI, 1.6-4.8]). The risk for those who worked in agriculture and subsequently worked in automotive-related manufacturing was further elevated (OR = 4.0 [95% CI, 1.7-9.9]). The risk for those employed in agriculture and subsequently employed in health care was also elevated (OR = 2.3 [95% CI, 1.1-4.6]). Farming tended to be among the earlier jobs worked, often during adolescence. While this article has limitations including the small sample size and the lack of information regarding specific exposures, it does provide evidence of a possible association between farming and breast cancer. The findings indicate the need for further study to determine which aspects of farming may be of biological importance and to better understand the significance of timing of exposure in terms of cancer risk.

The effectiveness of community interventions targeting HIV and AIDS prevention at young people in developing countries.

OBJECTIVE: To identify successful HIV/AIDS prevention interventions targeting youths and delivered in geographically bounded communities (for example, rural villages, urban settlements or neighbourhoods) in developing countries. METHODS: A systematic review and synthesis of studies evaluating interventions that were published between January 1990 and December 2004 was conducted. Using predetermined criteria, all interventions were summarized into multiple tables to facilitate comparison. Results of the evaluations of each of four types of intervention were reviewed using predetermined thresholds of evidence. The four types of interventions were classified as follows. Type 1 interventions were those targeting youths and delivered through existing organizations or centres that served youths. Type 2 were those targeting youths but not affiliated with existing organizations or centres. Type 3 were those targeting all community members and delivered through traditional kinship networks. Type 4 were those targeting communities as a whole and delivered through community-wide events. FINDINGS: Evaluations of 22 interventions were reviewed. Type 1 interventions produced primarily positive results at the required threshold of evidence. They are recommended for use in scaling-up projects but should be subject to continued rigorous evaluations. Studies of all other intervention types produced primarily positive results, but the evaluations were less rigorous so clear conclusions could not be drawn about their effectiveness. It is recommended that these interventions be continued and that priority should be given to implementing rigorous evaluations of these interventions. CONCLUSIONS: Considerable creativity, ingenuity and commitment is demonstrated in designing and delivering HIV interventions but there is a paucity of adequate evidence of their effectiveness. This precludes identification of the types of interventions that actually produce the targeted changes. It is essential that governments and donor agencies invest in high quality process and outcome evaluations and cost-benefit analyses so that effective interventions can be identified and promoted.

Challenges of a pandemic: HIV/AIDS-related problems affecting Kenyan widows.

The paper reports the findings of a qualitative study using focus group discussions and in-depth interviews about the challenges faced by widows as they confront the direct and indirect impacts of HIV/AIDS in Nyanza, Kenya. Two focus groups were conducted with widows from two community-based organizations. This was followed by in-depth interviews with four members and two leaders from each of the community-based organizations. The contents were analysed using grounded theory. The findings reveal several challenges encountered by widows in their struggles with the direct and indirect impacts of HIV/AIDS. Widows who know or do not know their HIV status are conscious about the possibility of contracting or transmitting the virus. Wife inheritance (a Luo custom), emerged as an outstanding issue for the widows in the context of HIV/AIDS transmission. The widows employ various strategies to resist being inherited. Widows in the current epidemic navigate issues of sexuality in various ways, such as insisting their partners use condoms or permanently abstaining from sexual intercourse.

Making a place for escort work: a case study.

This case study focused on the steps taken by a Canadian city bordering the United States to manage the commercial sex component of an adult entertainment package that draws many American visitors. It explored how the city dealt with the potential of community stigmatization resulting from its growing reputation as a place for easily accessible sex trade. The distinctive Canadian laws related to the sex industry, the predominantly laissez-faire attitude toward people's sex lives, and concerns about maintaining the atmosphere of safety and privacy protection preferred by many residents set boundaries to the approach that could be taken. The specific historical, geographic, social, and political location of the city figured prominently in its choice of a normalization rather than a spatialization strategy.

The sexual scripts of Kenyan young people and HIV prevention.

The scripting of sexual encounters among young people in Kenyan is described using results of 28 focus group discussions conducted with young people attending primary school standard 7, from four different ethnic groups and living in 22 different communities. Sexual encounters were described as both mundane and inevitable and followed a predetermined scripted sequence of events and interactions in which girls and boys played complementary roles. These scripts were set within discourses of force and the exchange of gifts for sex. The gendered nature of the script and its social and cultural foundations are discussed. Potential strategies for developing HIV prevention programming are discussed from the perspective of existing sexual scripts.

School-based HIV prevention programmes for African youth.

The high rate of HIV infection among youth in Africa has prompted both national and international attention. Education and prevention programmes are seen as the primary way of decreasing this rate. This paper reviews 11 published and evaluated school-based HIV/AIDS risk reduction programmes for youth in Africa. Most evaluations were quasi-experimental designs with pre-post test assessments. The programme objectives varied, with some targeting only knowledge, others attitudes, and others behaviour change. Ten of the 11 studies that assessed knowledge reported significant improvements. All seven that assessed attitudes reported some degree of change toward an increase in attitudes favourable to risk reduction. In one of the three studies that targeted sexual behaviours, sexual debut was delayed, and the number of sexual partners decreased. In one of the two that targeted condom use, condom use behaviours improved. The results of this review suggest that knowledge and attitudes are easiest to change, but behaviours are much more challenging. The article provides details about programmes and identifies characteristics of the most successful programmes. Clearly, however, more research is needed to identify, with certainty, the factors that drive successful school-based HIV/AIDS risk reduction programmes in Africa.

Assumptions and values of community health psychology.

There is a need to widen the practice of health psychologists to include the theories and methods of community psychology and an awareness of contemporary issues in community health. The aim of such a community health psychology would be both to deepen our understanding of the aetiology of health and illness in society and to develop strategies that will contribute to a reduction in human suffering and an improvement in quality of life. The aim of this article is to review the background and assumptions of community health psychology and to consider some values that would underlie such an approach.

Casual sex among Australian schoolies.

This study of the casual sexual partnering of 570 male and 776 female Australian high school students on a schoolies week vacation expands on earlier research on factors that influence the sexual activity of vacationing youth. Over 60% of the men and nearly 40% of the women who engaged in sexual intercourse during schoolies week did so with a casual partner. We used logistic regression to test an expanded version of Triandis Theory of Interpersonal Behavior (TIB) in explaining casual sexual partnering. Situational experiences (similar to what others have called situational disinhibition), prior sexual experiences and intentions (similar to what others have called spillover) influenced casual sexual partnering. Different causal pathways were demonstrated for men and women.

To work or not to work: combination therapies and HIV.

The authors describe the labor force experiences of people living with HIV and AIDS (PHAs) who are taking combination therapies using information from in-depth interviews conducted in 1999 and 2000 in the Windsor and Essex County region of Canada with 35 PHAs. They analyze labor force experience contextually, setting it within the contexts of personal illness experience (including disease trajectory and treatment history), workplace structure and discrimination, the labor market, and the structure of health and social service systems. Barriers to returning to or remaining in the labor force are numerous and require a specific commitment to overcome. Existing workplace and government policies and programs and labor market conditions impede labor force participation for PHAs who have recovered from serious illness and are now able and willing to work.
