Selected AbstractsLosartan reduces the costs of diabetic end-stage renal disease: An Asian perspectiveNEPHROLOGY, Issue 5 2005WONG KOK SENG SUMMARY: Objective: To evaluate losartan and conventional antihypertensive therapy (CT) compared with CT alone on the cost associated with end-stage renal disease (ESRD) in Hong Kong, Japan, Korea, Malaysia, Singapore and Taiwan. Methods: Reduction of end-points in non-insulin-dependent diabetes mellitus with the angiotensin II antagonist losartan (RENAAL) was a multinational, double-blind, randomized, placebo-controlled trial to evaluate the renal protective effects of losartan on a background of CT in patients with type 2 diabetes and nephropathy. The primary composite end-point was a doubling of serum creatinine, ESRD or death. Data on the duration of ESRD for the Asian subgroup of patients enrolled in RENAAL were used to estimate the economic benefits of slowing the progression of nephropathy. The cost associated with ESRD was estimated by combining the number of days each patient experienced ESRD with the average daily cost of dialysis from the third-party payer perspective in Hong Kong, Japan, Korea, Malaysia, Singapore and Taiwan. Total cost, converted to US dollars, was the sum of ESRD and losartan costs. Results: Losartan plus CT reduced the number of days with ESRD by 37.9 per patient over 3.5 years compared with CT alone. This reduction in ESRD days resulted in a decrease in the cost associated with ESRD, which ranges from $910 to $4346 per patient over 3.5 years across the six countries or regions. After accounting for the cost of losartan, the reduction in ESRD days resulted in net savings in each of the six countries or regions, ranging from $55 to $515 per patient. Conclusion: Treatment with losartan in patients with type 2 diabetic nephropathy not only reduced the incidence of ESRD among Asian patients, but resulted in direct medical cost savings in countries or regions representing Asia. [source] The Asian birth outcome gapPAEDIATRIC & PERINATAL EPIDEMIOLOGY, Issue 4 2006Cheng Qin Summary Asians are often considered a single group in epidemiological research. This study examines the extent of differences in maternal risks and birth outcomes for six Asian subgroups. Using linked birth/infant death certificate data from the State of California for the years 1992,97, we assessed maternal socio-economic risks and their effect on birthweight, preterm delivery (PTD), neonatal, post-neonatal and infant mortality for Filipino (87 120), Chinese (67 228), Vietnamese (45 237), Korean (23 431), Cambodian/Laotian (21 239) and Japanese (18 276) live singleton births. The analysis also included information about non-Hispanic whites and non-Hispanic blacks in order to give a sense of the magnitude of risks among Asians. Logistic regression models explored the effect of maternal risk factors and PTD on Asian subgroup differences in neonatal and post-neonatal mortality, using Japanese as the reference group. Across Asian subgroups, the differences ranged from 2.5- to 135-fold for maternal risks, and 2.2-fold for infant mortality rate. PTD was an important contributor to neonatal mortality differences. Maternal risk factors contributed to the disparities in post-neonatal mortality. Significant differences in perinatal health across Asian subgroups deserve ethnicity-specific interventions addressing PTD, teen pregnancy, maternal education, parity and access to prenatal care.

Abstract BACKGROUND Asian Americans have lower cancer screening rates compared with non-Hispanic whites (NHWs). Little is known about mechanisms that underlie disparities in cancer screening. The objectives of the current study were 1) to determine the relation between nativity, years in the United States, language, and cancer screening in NHWs and Asian Americans, independent of access to care and 2) to determine whether Asians reported different reasons than NHWs for not obtaining cancer screening. METHODS This population-based study included 36,660 NHWs, 1298 Chinese, 944 Filipinos, 803 Koreans, 857 Vietnamese, and 1036 Other Asians from the 2001 California Health Interview Survey. The main study outcomes were 1) self-reported colorectal, cervical, and breast cancer screening and 2) reasons for not obtaining cancer screening. RESULTS After adjusting for access to care, several Asian subgroups still had significantly lower rates of all types of cancer screening compared with NHWs. Adjusting for nativity, years in the United States, and English language attenuated the relation between Asian ethnicity and lower rates of colorectal and breast cancer screening. When they were asked what the most important reason was for not having each screening test, foreign-born Asians were significantly more likely than United States-born NHWs to report that they "didn't have problems/symptoms" (P<.01). CONCLUSIONS Nativity, years in the United States, and English language may be markers of cultural differences that are mediating cancer screening disparities. Foreign-born Asians may believe that cancer screening is in response to symptoms rather than tests that are used prior to the development of symptoms. Health education messages must consider how to communicate effectively that "cancer screening is valuable, because it finds cancer before it is advanced enough to cause symptoms."

[source] English language proficiency and smoking prevalence among California's Asian Americans,CANCER, Issue S12 2005Hao Tang M.D., Ph.D. Abstract The authors documented California's tobacco control initiatives for Asian Americans and the current tobacco use status among Asian subgroups and provide a discussion of the challenges ahead. The California Tobacco Control Program has employed a comprehensive approach to decrease tobacco use in Asian Americans, including ethnic-specific media campaigns, culturally competent interventions, and technical assistance and training networks. Surveillance of tobacco use among Asian Americans and the interpretation of the results have always been a challenge. Data from the 2001 The California Health Interview Survey (CHIS) were analyzed to provide smoking prevalence estimates for all Asian Americans and Asian-American subgroups, including Korean, Filipino, Japanese, South Asian, Chinese, and Vietnamese. Current smoking prevalence was analyzed by gender and by English proficiency level. Cigarette smoking prevalence among Asian males in general was almost three times of that among Asian females. Korean and Vietnamese males had higher cigarette smoking prevalence rates than males in other subgroups. Although Asian females in general had low smoking prevalence rates, significant differences were found among Asian subgroups, from 1.1% (Vietnamese) to 12.7% (Japanese). Asian men who had high English proficiency were less likely to be smokers than men with lower English proficiency. Asian women with high English proficiency were more likely to be smokers than women with lower English proficiency. Smoking prevalence rates among Asian Americans in California differed significantly on the basis of ethnicity, gender, and English proficiency. English proficiency seemed to have the effect of reducing smoking prevalence rates among Asian males but had just the opposite effect among Asian females. Cancer 2005. © 2005 American Cancer Society.
