Design: Cross-sectional postal survey assessing demographic characteristics and vaccine knowledge.
Setting: British Columbia (BC).
Community research into women's experiences in the indoor commercial sex industry illustrated an urgent need for sexually transmitted infection (STI) and HIV education, prevention, testing, and treatment and culturally appropriate services to support the sexual and reproductive health of commercial sex workers (CSWs). This work also revealed that a high number of immigrant--primarily Asian--women are involved in the indoor sex industry. In response, the authors developed a community-academic research partnership to design and implement a blended outreach research program to provide STI and HIV prevention interventions for indoor CSWs and their clients.

At present, pregnant women are only screened if they fit risk criteria, which may result in under-identification of HCV in this population. The purpose of this study was to determine the overall prevalence rate, age and geographic distribution of reported HCV infection among pregnant women in BC, and compare results to a previously conducted anonymous seroprevalence survey.

Background: Immunization is an important and effective public health intervention. Understanding immunization providers' attitudes and beliefs toward immunization has the potential to improve educational efforts and lead to behavioural change.
Background: The purpose of this study was to: (a) compare rates of local reactions from meningococcal C conjugate (Neis Vac-C) and hepatitis B vaccines (Recombivax HB), and (b) compare local reactions when both injections were given in one arm versus one in each arm.
Methods: Schools were randomized to have grade six students receive both vaccines in one arm (One Arm Group), or one vaccine in each arm (Two Arm Group; MCC always given in left arm). Structured telephone interviews of parents were conducted, and respondents were asked about local and systemic reactions, interference with school or other activities, need for medical attention, and lost parental work time.

Background: A relationship between Chlamydia pneumoniae infection and acute coronary syndromes has not been consistently found in published studies. It has been hypothesized that a bacteriophage-infected subset of C pneumoniae may be uniquely equipped to promote atherosclerosis and acute coronary syndromes through the expression of phage genes.
Methods: The authors performed a pilot case-control study of acute coronary events.
Background: Concerns have been raised that parents may be reluctant to have their daughters receive the human papillomavirus (HPV) vaccine, because of a belief that doing so might be interpreted as condoning earlier and more frequent sexual activity. We determined intentions regarding vaccination among Canadian parents and factors that predicted parental intention to have their daughters vaccinated against HPV.
Methods: Parents of children 8-18 years of age, recruited from across Canada, were asked to respond to questions in the context of a grade 6, publicly funded, school-based HPV vaccine program.
Objectives: To determine whether "high-risk" clients occupied important sociometric positions in sexual networks of commercial sex workers and to estimate whether they were more likely to be HIV and STI infected.
Goal: To determine whether a classification of high-risk clients could be validated by network analysis.
Study Design: We used proxy data on clients collected from a cross-sectional survey of 49 indoor female sex workers.
Background: A review of infectious disease research activity and capacity was performed in British Columbia and linked to a process for identifying needs, gaps and opportunities from a public health perspective.
Methods: The study was organized in three phases: an environmental scan to describe current research activity in BC; a consultation to identify needs, gaps and opportunities with those conducting research (key informants) and the end users of research results (stakeholders); and a prioritization of the research needs emerging from the consultation.
Results: Analysis and synthesis of the consultation data resulted in the identification of nine research themes, which were prioritized in the following order: efficacy and cost-benefit, disease patterns, emerging infectious disease, immunology and vaccines, disease-specific research, health promotion and communications, safe food and water, knowledge translation research and genomics.

Background: Although comprising up to 80% of the commercial sex industry in Canada, indoor female sex workers (FSW) are generally not represented in research because they are a hidden population and difficult to access.
Objectives: This paper describes a community-academic partnership model that was established to gain access to, deliver outreach services to, and conduct community-based research with the indoor commercial sex industry in four cities in British Columbia.
Methods: The project employed an ongoing community consultation, peer-delivered approach to reaching this overlooked segment of the commercial sex industry.
Background: We undertook a study to examine the fertility intentions and reproductive health issues of women living with HIV in a broad-based sample in British Columbia, Canada.
Methods: Between November 2003 and December 2004, we invited women with HIV at all HIV clinics and AIDS service organizations in the province of British Columbia, Canada, to complete the survey instrument 'Contraceptive Decisions of HIV-positive Women'. Logistic regression analysis was conducted to calculate adjusted odds ratios to identify factors that may be significant predictors of the intention of women living with HIV to have children.
Objectives: We assessed adverse events, including oculorespiratory syndrome, following influenza immunization during the first year of a publicly-funded program for infants, toddlers and their household members in Canada.
Methods: Parents bringing infants and toddlers for influenza immunization to clinics in Quebec or British Columbia consented to structured telephone interview 5 to 10 days later. One adult provided information for all household members.
To assess the reproducibility of measurements of cervical and vaginal human immunodeficiency virus (HIV) viral load, 92 duplicate cervical and 88 duplicate vaginal samples were collected from 13 HIV-infected women using Sno Strip filter-paper wicks. RNA was eluted from the strips, extracted, and assayed using a modified protocol for the Roche Cobas Amplicor HIV-1 Monitor assay. Pearson's correlation coefficient (R), coefficient of determination (D), and Bland-Altman plots (BA) were used to compare paired log10-transformed viral loads.

Methods: A cross-sectional observational data set was created using an anonymous 61-item self-administered survey.
Results: Eighty-three percent (104/126) of eligible inmates participated.
Background: Lifetime protection against pertussis has been adopted as a goal of immunization programs in Canada. To anticipate adult coverage with a combined product containing tetanus (T) and diphtheria (d) toxoids and acellular pertussis (aP) vaccine as a booster dose, we conducted a survey of households in British Columbia, Canada.
Methods: In a random telephone survey involving 800 adults, 25 years of age and older, we assessed current behaviors related to adult Td immunization and beliefs regarding pertussis vaccine under various scenarios relevant to adult decision-making.
We investigated personal protective behaviors against West Nile virus infection. Barriers to adopting these behaviors were identified, including the perception that DEET (N,N-diethyl-m-toluamide and related compounds) is a health and environmental hazard. Televised public health messages and knowing that family or friends practiced protective behaviors were important cues to action.

Methods: A retrospective cohort study, through review of maternal and neonatal charts and placental pathology, of 100 sequential pregnancies in which placentas were submitted to pathology. Data were examined using descriptive statistics, and proportional differences were compared using the chi-square test and Fisher's exact test.
Objective: The purpose of this study was to determine the vaginal, cervical, and plasma viral load through the menstrual cycle in women who are positive for human immunodeficiency virus.
Study Design: A prospective cohort study was performed on 14 women with ovulatory menstrual cycles who have human immunodeficiency virus. Duplicate cervical and vaginal viral load samples (n = 301) were taken at four stages (menstrual, follicular, periovulatory, and luteal) of two consecutive cycles.
