Cost effectiveness of cervical cancer screening among Chinese women in North America.

BACKGROUND: Chinese North American women have high invasive cervical cancer rates and low screening rates. The cost-effectiveness of strategies to improve Pap testing rates for Chinese women living in Seattle, Washington and Vancouver, British Columbia was examined. OBJECTIVES: To calculate the costs and cost-effectiveness of implementing two strategies to motivate women to obtain a Pap smear. RESEARCH DESIGN: A three-armed randomized, controlled trial was conducted. Women in each of two interventions (high-intensity outreach and low-intensity mailing intervention) were compared to a group of women who received usual care. MEASURES: Costs were captured via a group discussion of costs, accounting records, sampling of staff time logs, and estimation of costs and task times. Effectiveness was measured as the proportion of women in each intervention arm who reported receiving a Pap smear since the trial began. Cost-effectiveness was calculated as the incremental cost of screening each additional woman between an intervention arm and the control arm. RESULTS: A greater percentage of women who received the outreach intervention had a Pap test than women who received mailed materials or women who were in the usual care arm. The intent-to-treat cost for each additional woman to be screened for a Pap test was $415 in the Outreach arm and $676 for the Direct Mailing arm. The outreach worker intervention, though more expensive overall, was more cost-effective than the mailing intervention. CONCLUSIONS: Outreach intervention is cost-effective for sponsors and should be considered as a strategy to motivate Chinese women living in North America to seek cervical cancer screening.

Predisposing, reinforcing and enabling factors associated with hepatitis B testing in Chinese Canadians in British Columbia.

BACKGROUND: Liver cancer, a significant health problem in Chinese, can be controlled through HBV blood testing, vaccination, and community education about HBV. The PRECEDE framework has been very helpful in identifying factors associated with health practices. OBJECTIVES: The objective was to identify factors associated with HBV testing in Chinese Canadians, using the PRECEDE framework. METHODS: Five hundred and thirty-three randomly selected Chinese Canadian adults were interviewed about HBV blood testing practices. Factors were grouped as predisposing, reinforcing and enabling. RESULTS: Fifty-five percent had received HBV blood testing. Several predisposing factors, all reinforcing factors and one enabling factor were associated with HBV testing in bivariate analysis. A physician's recommendation for testing was the strongest factor associated with testing in multiple logistic regression analysis (OR=4.4, p<0.0001). INTERPRETATION: Many Chinese Canadian adults in Vancouver have not been tested for HBV. Continuing educational efforts are needed and the PRECEDE framework can inform the development of health education interventions.

Tobacco knowledge and beliefs in Chinese American men.

BACKGROUND: Chinese American men have relatively high smoking rates. However, there are limited data about the tobacco-related knowledge, attitudes, and beliefs of this racial/ethnic group. METHODS: We conducted a community-based telephone survey in Seattle, Washington during 2004. Households were identified by applying a previously validated list of Chinese last names to an electronic version of the Seattle telephone book. Interviews were completed in Cantonese, Mandarin, or English. Survey items addressed tobacco knowledge, cultural beliefs, and practices. RESULTS: The study sample included 168 Chinese American men. Current, former, and never smoking rates were 22%, 42%, and 36%, respectively. Current smokers were less likely to be proficient in English than never smokers, and were less likely to have a regular doctor than former smokers. They also had lower levels of knowledge about the health effects of tobacco, and were more likely to have traditional Chinese cultural beliefs about tobacco use than non-smokers. CONCLUSION: Tobacco use continues to be a public health problem among Chinese American men. Smoking cessation programs should target men with limited English proficiency and those without a regular source of health care. Educational materials should specifically address the negative health effects of smoking. They should also both acknowledge and address Chinese cultural beliefs about tobacco use.

Hepatitis B knowledge and practices among Chinese immigrants to the United States.

INTRODUCTION: Chinese immigrants to the United States experience high rates of liver cancer. Chronic carriage of hepatitis B virus (HBV) is the most common underlying cause of liver cancer among Chinese Americans. Our objective was to describe Chinese immigrants' hepatitis B knowledge, testing, and vaccination levels. METHODS: A community-based, in-person survey of Chinese men and women was conducted in Seattle during 2005. Our study sample included 395 individuals. RESULTS: Less than one-half (48%) of our study group indicated they had received a hepatitis B blood test, and about one-third (31%) indicated they had been vaccinated against hepatitis B. The proportions of respondents who knew HBV can be spread during childbirth, during sexual intercourse, and by sharing razors were 70%, 54%, and 55%, respectively. Less than one-quarter of the study group knew that HBV cannot be spread by eating food that was prepared by an infected person (23%) and by sharing eating utensils with an infected person (16%). DISCUSSION: Over 50% of our respondents did not recall being tested for HBV. Important knowledge deficits about routes of hepatitis B transmission were identified. Continued efforts should be made to develop and implement hepatitis B educational campaigns for Chinese immigrant communities.
