Fertility and reproductive choice in women with HIV-1 infection.

OBJECTIVE: To measure fertility and birth rates and to describe the reproductive histories of women diagnosed with HIV-1 infection in Australia. METHODS: The medical records of 294 women with HIV-1 infection in four states of Australia were reviewed. Expected fertility and birth rates were calculated using national statistics. RESULTS: In the study population, 152 (52%) women had at least one pregnancy prior or subsequent to HIV-1 diagnosis. At maternal HIV-1 diagnosis, 71 (24%) women had a total of 106 children aged under 15 years. During the study period, 246 women were aged 15, 44 years and 58 (23%) of these became pregnant after HIV-1 diagnosis. Women whose exposure to HIV-1 was injecting drug use were twice as likely to become pregnant and more likely to have multiple pregnancies than women who did not report injecting drug use. The annual general fertility rate was 30 per 10,000 compared with 63 per 10,000 for the Australian female population aged 15-44 years, and the birth rate in women with HIV-1 infection was one-half that of the general female population. Of pregnancies confirmed after HIV-1 diagnosis, 47% were voluntarily terminated, a rate more than double that of the general population. All multiple terminations were among women whose exposure to HIV-1 was injecting drug use. CONCLUSIONS: Fertility and birth rates among women with HIV-1 infection are lower than the general population and the rate of termination higher. The results of this study provide a basis for the management of women with HIV-1 infection who are considering pregnancy.

PIP: Review of the medical records of 294 HIV-1-infected women in four states of Australia found the fertility and birth rates among those women to be lower and the rate of pregnancy termination higher than those of the general female Australian population. Expected fertility and birth rates were calculated using national statistics. 152 women had at least one pregnancy before or subsequent to HIV-1 diagnosis. At maternal HIV-1 diagnosis, 71 women had a total of 106 children under age 15 years. During the study period of 1987-92, 58 of the 246 women aged 15-44 years became pregnant after HIV-1 diagnosis. Women whose exposure to HIV-1 was IV drug use were twice as likely to become pregnant and more likely to have multiple pregnancies than women who did not report such drug use. The annual general fertility rate was 30/10,000 compared to 63/10,000 for the general Australian female population, while the birth rate among HIV-1-infected women was also half that of the general female population. Of pregnancies confirmed after HIV-1 diagnosis, 47% were voluntarily terminated, a rate more than double that of the general population. All multiple terminations were among women whose exposure to HIV-1 was through IV drug use.

Watching the Games: public health surveillance for the Sydney 2000 Olympic Games.

STUDY OBJECTIVE: To describe the development of the public health surveillance system for the Sydney 2000 Olympic Games; document its major findings; and discuss the implications for public health surveillance for future events. DESIGN: Planning for the system took almost three years. Its major components included increased surveillance of communicable diseases; presentations to sentinel emergency departments; medical encounters at Olympic venues; cruise ship surveillance; environmental and food safety inspections; surveillance for bioterrorism; and global epidemic intelligence. A daily report integrated data from all sources. SETTING: Sydney, Australia. Surveillance spanned the period 28 August to 4 October 2000. PARTICIPANTS: Residents of Sydney, athletes and officials, Australian and international visitors. MAIN RESULTS: No outbreaks of communicable diseases were detected. There were around 5% more presentations to Sydney emergency departments than in comparable periods in other years. Several incidents detected through surveillance, including injuries caused by broken glass, and a cluster of presentations related to the use of the drug ecstasy, prompted further action. CONCLUSIONS: Key elements in the success of public health surveillance for the Games included its careful planning, its comprehensive coverage of public health issues, and its timely reporting and communication processes. Future systems need to be flexible enough to detect the unexpected.

Epidemiological evidence for a relationship between life events, coping style, and personality factors in the development of breast cancer.

OBJECTIVE: Review empirical evidence for a relationship between psychosocial factors and breast cancer development. METHODS: Standardised quality assessment criteria were utilised to assess the evidence of psychosocial predictors of breast cancer development in the following domains: (a) stressful life events, (b) coping style, (c) social support, and (d) emotional and personality factors. RESULTS: Few well-designed studies report any association between life events and breast cancer, the exception being two small studies using the Life Events and Difficulties Schedule (LEDS) reporting an association between severely threatening events and breast cancer risk. Seven studies show anger repression or alexithymia are predictors, the strongest evidence suggesting younger women are at increased risk. There is no evidence that social support, chronic anxiety, or depression affects breast cancer development. With the exception of rationality/anti-emotionality, personality factors do not predict breast cancer risk. CONCLUSION: The evidence for a relationship between psychosocial factors and breast cancer is weak. The strongest predictors are emotional repression and severe life events. Future research would benefit from theoretical grounding and greater methodological rigour. Recommendations are given.

Monitoring acute diseases during the Sydney 2000 Olympic and Paralympic Games.

The Sydney 2000 Olympic Games (the XXVII Olympiad) will be the biggest peacetime event ever held in Australia. During the Games, all public health decisions will be centralised, with daily briefing sessions held to review emerging public health issues and facilitate responses. Infectious diseases will be monitored and reported through the Olympic Surveillance System, with particular attention to foodborne diseases and conditions spread via the respiratory route. This system relies heavily on the cooperation of key notifiers such as emergency departments, laboratories and general practitioners. The lessons learned during the Games, and the new and enhanced systems and linkages that have been developed to support it, will strengthen future disease surveillance in NSW.

Hepatitis A in south-eastern Sydney 1997-1999: continuing concerns for gay men and an outbreak among illicit drug users.

The incidence of hepatitis A virus (HAV) in south-eastern Sydney is one of the highest in Australia with large outbreaks previously associated with male-to-male sexual contact. We report HAV notification trends over the period 1 June 1997 to 31 May 1999 for this location. In the first twelve-month period, 233 cases were notified (crude rate 30.5/100,000 per year) with a peak incidence of 110/100,000 in males aged 20-39 years. Over 60% of male cases reported male-to-male sexual contact. The notification rate (crude rate 15.5/100,000) and proportion of males (61%) was considerably lower in the following twelve month period with 118 cases notified. Less than a third of males reported male-to-male sexual contact. An outbreak (n = 45) of HAV among illicit drug users and their contacts was detected in December 1998. The transmission of HAV remains endemic in south-eastern Sydney. Vaccination among high-risk groups remains an important preventive strategy.
