Drug use behaviors among Asian drug users in San Francisco.

Due to a pervasive bias toward Asian Americans, such as tendency to view Asian Americans as model minorities, drug use behaviors among them are often ignored by health professionals, researchers, and community members, including Asian community members. This study identified patterns of drug use behaviors in relation to cultural factors among Asian drug users in San Francisco, CA. A sample of 92 Asian drug users (35 Chinese, 31 Filipino, 26 Vietnamese) who were not currently enrolled in drug treatment programs were recruited through targeted sampling methods and interviewed using a questionnaire with open-ended questions. The study evaluated responses of the participants and used content analyses. This study clearly revealed that the patterns of drug use among Asian drug users are unique to their ethnicity, gender, immigrant status, and age groups. Also, Asian drug users share cultural constructs related to drug use such as fear of addiction and injecting drugs, and stigma attached to drug users in the community. Therefore, drug abuse prevention programs should address both common factors among Asian drug users, as well as unique factors in specific target groups (e.g., ethnic groups, Asian immigrants, Asian women, refugees, and adolescents).

AIDS among Asians and Pacific Islanders in the United States.

OBJECTIVE: To characterize Asians and Pacific Islanders in the United States with reported acquired immunodeficiency syndrome (AIDS). METHODS: AIDS surveillance data reported through June 1998 were analyzed. Characteristics of cumulative case patients, rates of AIDS incidence in 1996 through 1997, and trends from 1982 through 1996 were analyzed. RESULTS: Through December 1998, 4,928 Asian and Pacific Islander adults and 46 Asian and Pacific Islander children with AIDS were reported in the United States. Of the total cases, 89% were in men, and 79% of those were in men who have sex with men (MSM). Five states, which account for 63% of the Asian and Pacific Islander population in the United States, reported 78% of the cases: California (45%), Hawaii (12%), New York (15%), Texas (3%), and Washington (3%). Of the 92% of Asian and Pacific Islander patients with country of birth information, 59% were foreign-born, a percentage that corresponds to the distribution in the general population. The overall incidence rate per 100,000 for 1996 through 1997 was 12.8 (21.3 for men; 3.3 for women). The highest rate was in the Northeast (15.9), followed by the West (13.8), South (10.6), and Midwest (5.7). Tuberculosis, reported for 6% of Asians and Pacific Islanders, was higher among foreign-born than among U.S.-born Asians and Pacific Islanders (8% and 4%, respectively). Between 1982 and 1996, AIDS incidence among MSM increased and peaked in 1994. Among heterosexual contacts and injection drug users, incidence has increased but remained low. CONCLUSIONS: The AIDS epidemic among Asians and Pacific Islanders in the United States has primarily affected MSM and is concentrated in a few states where most Asians and Pacific Islanders reside. Prevention activities should include consideration of cultural diversity and an understanding of cultural norms regarding sexuality. Additional information on risk behaviors and seroprevalence among Asian and Pacific Islander MSM is needed to better guide prevention planning.

South Asian patients' views and experiences of clinical trial participation.

OBJECTIVES: This paper explores South Asian patients' views and experiences of clinical trial participation, as part of a larger study which sought to assess British South Asian under-representation in clinical trials. METHODS: The study was based on semi-structured interviews with South Asian trial participants in primary care and specialist treatment centres in the north of England. Fifteen South Asian patients who had participated in one of six different clinical trials to test pharmaceutical products comprised the study cohort. RESULTS: South Asian motivations to participate in clinical trials are similar to those of the majority 'White' population. Clear and concise trial information (provided by caring and understanding trial staff) was considered an important aspect of the respondents' experiences. Appealing to South Asian peoples' altruistic nature by making them aware of South Asian under-representation (especially in clinical trials that investigate illnesses prevalent in their community) was also identified as a strong motivational factor. Potential barriers to their participation included: trial burden (which bears heavily on the poor), language, and discriminatory practices in the NHS, which can lead to mistrust of health professionals. In addition, female modesty and preference for female trial staff was recognized as a 'cultural' barrier to participation. CONCLUSION: There are more similarities than differences between the experiences of British South Asians and 'White' trial participants. Present findings suggest that ethnicity operates at different levels. In addition to South Asian trial participants' culture, social class and gender are also as likely to affect their participation in clinical trials. To improve South Asian accrual rates, strategies should be designed to take into consideration linguistic differences and improving overall trust in the clinical trial team.

Predicted and observed cardiovascular disease in South Asians: application of FINRISK, Framingham and SCORE models to Newcastle Heart Project data.

BACKGROUND: South Asian populations in the United Kingdom have a high risk of cardiovascular disease (CVD) mortality. Risk prediction models appear to be inaccurate in South Asians. OBJECTIVE: To explore the predictive capacity of the FINRISK, Framingham (1991) and SCORE risk prediction models in the Newcastle Heart Project population (n = 1301). METHODS: Mortality data for England and Wales were used to define the expected ranking of CVD risk by country of birth. CVD mortality in the Newcastle Heart Project sample was examined. Risk factor measures were obtained from the Newcastle Heart Project, where 90 percent of South Asians were born in the Indian Subcontinent. The predicted outcomes for FINRISK were acute myocardial infarction and CHD mortality, for Framingham CHD mortality, myocardial infarction, new angina and coronary insufficiency and for SCORE CHD and non-CHD CVD mortality. RESULTS: The FINRISK model predicted in South Asian men combined, compared with Europeans, a risk ratio of 122 per cent (SMR 142) with substantial subgroup heterogeneity, e.g. 154 per cent in Bangladeshis (SMR 151), 129 per cent in Pakistanis (SMR 148), 99 per cent in Indians (SMR 142). The FINRISK risk ratios for South Asian women combined were 160 per cent (SMR 145), for Bangladeshis 184 per cent (SMR 91), Pakistanis 172 per cent (SMR 111) and for Indians 145 per cent (SMR 158). The Framingham model results were very similar to FINRISK, but the SCORE model showed comparatively low 10 year risk in all South Asian groups. Both the Framingham stroke model and the SCORE non-CHD CVD model predicted comparatively low rates, while national data showed these to be high. Control of the five major risk factors was modelled by FINRISK to reduce risk by about 59 per cent in South Asian men and 67 per cent in South Asian women, with some subgroup heterogeneity, compared to 50 per cent in European men and 48 per cent in European women. The Framingham model results were similar. The absolute rates for each ethnic group varied by model. CONCLUSION: The Framingham and FINRISK models gave similar results, mostly following expected patterns, but the SCORE model did not, probably reflecting its lack of inclusion of HDL and diabetes as risk factors. National mortality data and modelled predictions agreed reasonably well for South Asians combined, and Bangladeshi and Pakistani men, but not for Indian men and Pakistani and Bangladeshi women. The varying rates show the limits of modelling. The models suggest the potential gains from controlling major established risk factors could be substantial in South Asians and greater than in Europeans.

Improved survival of Asians with corpus cancer compared with whites: an analysis of underlying factors.

OBJECTIVE: To compare the clinicopathologic prognosticators and survival of Asians and whites with corpus cancer. METHODS: Demographic, clinicopathologic, and survival data were obtained from the 1992-2001 Surveillance, Epidemiology, and End Results Program. Statistical analyses were performed by Kaplan-Meier methods and Cox proportional hazards model. RESULTS: A total of 2,144 Asians and 32,999 whites with corpus cancer were identified. The age-adjusted incidence of uterine cancer in Asians compared with whites was 16.8 compared with 26.1 per 100,000. Asians presented at a younger age (mean 58.4 years compared with 65.1; P < .01) and with more advanced stage disease than whites (21.5% compared with 15.4%; P < .01). The 5-year survival rate for Asians was 79.4% compared with 75.2% for whites (P < .01). Asians with stage I-II and III-IV cancers had 5-year survival rates of 89.3% and 41.2% compared with 82.3% and 34.0% for the whites, respectively (P < .01, early stage; P < .01, advanced stage). The survival advantage of Asians persists in endometrioid (P < .01) and uterine papillary serous carcinomas (P < .01), but not in clear cell carcinoma (P = .62) or sarcomas (P = .78). In multivariate analysis, younger age (P < .01), earlier stage (P < .01), favorable histology (P < .01), and lower grade (P < .01) remained as significant independent prognosticators for improved survival. However, race was not an important prognosticator. CONCLUSION: The overall survival advantage experienced by Asians with uterine cancer is attributable to their younger age at diagnosis. Because Asian women present at a younger age with more advanced disease, physicians should have an increased index of suspicion for malignancy in young Asian women with suspicious symptoms and consider a lower age threshold for biopsy in this group. LEVEL OF EVIDENCE: II-2.

Asian MODY: are we missing an important diagnosis?

AIMS: Maturity onset diabetes of the young (MODY) is a monogenic form of diabetes where correct diagnosis alters treatment, prognosis and genetic counselling. The first UK survey of childhood MODY identified 20 White, but no Asian children with MODY. We hypothesized that MODY causes diabetes in UK Asians, but is underdiagnosed. METHODS: Children with dominant family histories of diabetes were recruited. Direct sequencing for mutations in the two most common MODY genes; HNF1A (TCF1) and GCK was performed in autoantibody-negative probands. We also compared MODY testing data for Asian and White cases from the Exeter MODY database, to 2001 UK census data. RESULTS: We recruited 30 families and identified three Asian families with MODY gene mutations (two HNF1A, one GCK) and three White UK families (two HNF1A, one GCK). Heterozygous MODY phenotypes were similar in Asians and Whites. Only eight (0.5%) of 1369 UK referrals for MODY testing were known to be Asian, but in 2001 Asians represented 4% of the English/Welsh population and have a higher prevalence of diabetes. CONCLUSIONS: We identified three cases of childhood MODY in UK Asians and demonstrated reduced rates of MODY testing in Asians, which has negative implications for treatment. It is unclear why this is. MODY should be considered in autoantibody-negative Asian diabetes patients lacking evidence of insulin resistance.

Cultural health care or child abuse? The Southeast Asian practice of cao gio.

Although the immigration of Southeast Asians more than doubled over the past 20 years, much misunderstanding still persists regarding traditional, culture-bound health practices used by Vietnamese, Cambodian and Laotian families. The research presented in this paper explains one such traditional practice, that of cao gio. Cao gio, a dermabrasion therapy, is used extensively by many Southeast Asian women to treat a variety of illnesses. Health care providers do not appreciate this practice, however, to the extent that it is claimed to be a form of child abuse in some of the literature reviewed. A better understanding of the practice by those involved in the primary care of Southeast Asian families is not only necessary, but essential to avoid the mislabeling and misinterpretation of cultural, traditional health practices as child abuse. Lack of awareness of Southeast Asian cultural practices is quite significant, even though the United States experienced three major waves of Southeast Asian immigration during the past 20 years (Takeuchi, & Young, 1994). Over the past decade, the number of Southeast Asian immigrants and refugees to the United States has increased 108% or by more than 1 million individuals (Fong, & Mokuau, 1994; Frank-Stromborg, 1991; Ja, & Aoki, 1993; Tran, 1991; U.S. Census Bureau, 1998). Yet, despite this, Southeast Asian individuals are poorly understood, and the literature reveals little about what health, illness and treatment constitute for these different cultures (Boston, 1992; Buchwald, Panwala, & Hooton, 1992). The ethnic groups that comprise Southeast Asians, formerly known as the Indochinese, include individuals from Vietnam, Cambodia and Laos (Catanzaro, & Moser, 1982; Chung, & Kagawa-Singer, 1993). The majority of these individuals are refugees who fled their countries due to political persecution (Toole, & Waldman, 1993). This paper describes the findings of a phenomenological research study completed among 19 Southeast Asian women regarding beliefs about health and health practices. The women discussed the practice of cao gio (phonetically pronounced as gow yaw) and its importance, effectiveness and significance to their cultures. The discussion relates the study findings to the debate and issues surrounding child abuse, the consequences of misreporting, as well as the consequences of cultural ignorance in the provision of health care to those of different cultural practices and beliefs, particularly those of Southeast Asian ethnicity.

Prepubertal Asians have less limb skeletal muscle.

Skeletal muscle mass in prepubertal Asian children has not been examined previously. The aims of this study were to test the hypotheses that 1) prepubertal Asians have less appendicular skeletal muscle (ASM) mass compared with African-Americans and Caucasians, and 2) ASM is less in prepubertal Asian girls compared with Asian boys. ASM was estimated by using dual-energy X-ray absorptiometry in healthy prepubertal girls (n = 170) and boys (n = 166). The results showed that, after adjusting for age, height, and body weight, 1) Asian girls and boys had less amounts of ASM than African-Americans (P < 0.001); 2) Asian girls had less amounts of ASM than Caucasian girls (P = 0.004); 3) there was a trend towards less ASM in Asian compared with Caucasian boys (P = 0.07); 4) and Asian girls had significantly less ASM than Asian boys (P < 0.001). This study indicates that skeletal muscle mass as a fraction of body weight is smaller in Asian compared with African-American and Caucasian children.

Complement C3 and C-reactive protein are elevated in South Asians independent of a family history of stroke.

BACKGROUND AND PURPOSE: Complement components are emerging risk factors for cardiovascular disease. In this study, we examined the relation among C3, C-reactive protein (CRP), factor B, and features of the insulin resistance (IR) syndrome in 143 first-degree relatives of South Asian subjects with ischemic stroke, 141 South Asian controls, and 121 white controls. METHODS: C3, CRP (high-sensitivity assay), and factor B levels were measured by ELISAs, and their relation to features of the IR syndrome were assessed. Data are presented as geometric mean (95% CI). RESULTS: There was no significant difference in the levels of C3 between South Asian relatives (1.25 [1.21, 1.29] g/L) and South Asian controls (1.20 [1.15, 1.24] g/L, P=0.2). Levels in both South Asian groups were significantly higher than in white controls (0.95 [0.92, 0.98] g/L; P<0.001 for both comparisons). These differences remained significant after adjustment for covariates. Similarly, levels of CRP were not different between the 2 South Asian groups, but levels in both South Asian groups, after adjustment for covariates, were significantly higher than in white controls. There was no difference in the levels of factor B among the 3 groups. South Asian subjects with elevated C3 levels clustered risk factors associated with IR to a greater extent than those with high CRP. CONCLUSIONS: These results suggest that South Asians have a greater level of chronic subclinical inflammation than do whites, independent of a family history of stroke. In addition, C3 is more likely to cluster with features of the IR syndrome compared with CRP in South Asians.

Calcium, vitamin D and parathyroid hormone relationships in pregnant Caucasian and Asian women and their neonates.

Plasma calcium, serum 25 hydroxyvitamin D [25(OH)D], 1,25 dihydroxyvitamin D[1,25(OH)2D] and parathyroid hormone (PTH) have been measured in pregnant and newborn Caucasians and Asians. Calcium and 25(OH)D concentrations were lower in Caucasian than in Asian women at all four stages (three trimesters and during labour) of pregnancy. PTH concentrations were greater in Asian than in Caucasian women during the three trimesters, but not at labour, and increased in both groups through pregnancy, without a concomitant change in plasma calcium concentrations. There was a significant inverse correlation between calcium and PTH, as well as 25(OH)D and PTH, concentrations. These data demonstrate the presence of progressive 'hyperparathyroidism' during pregnancy in Caucasian and Asian women. The higher PTH concentrations in Asian women may reflect the necessity of maintaining adequate plasma calcium concentrations through PTH-induced osteolysis in the face of vitamin D deficiency. Relative hyperparathyroidism in Asians may contribute to net loss of calcium from the skeleton and osteopenia in Asian women. Calcium, 25(OH)D and 1,25(OH)2D concentrations were lower, and those of PTH higher, in Asian newborns compared with Caucasian newborns. Serum 1,25(OH)2D concentrations in the Asian newborn, though lower than respective maternal levels, were comparable with normal adult levels, indicating that 1,25(OH)2D biosynthesis is stimulated in the Asian newborn to compensate for the low serum 25(OH)D concentrations.

Cultural barriers to health care for southeast Asian refugees.

Many Southeast Asians now living in the United States experience severe health problems, attributable to physical trauma and inadequate health care in Asia, and low socioeconomic status in this country. Evidence indicates that despite their health problems, Southeast Asian refugees underuse the American health care system. Cultural reasons for this underuse are examined. Southeast Asian cultural attitudes toward suffering, such as beliefs that suffering is inevitable or that one's life span is predetermined, can cause Southeast Asians not to seek health care. Cultural beliefs about the sources of illness and correspondingly appropriate forms of treatment can be a barrier to Western health care. Many lack familiarity with Western diagnostic techniques and treatments and thus are apprehensive. Health care providers' ignorance of Southeast Asian cultures can interfere with communication with patients, resulting in culturally irrelevant services or misinterpretation of side effects of Southeast Asian folk medicines. Southeast Asians' lack of familiarity with American culture can make health care services geographically and economically inaccessible and can cause Southeast Asians to be ignorant of available services or how to access them. An understanding of Southeast Asian cultures and additional outreach efforts by Western medical practitioners and health care providers are needed to improve the use of health care services by Southeast Asian refugees in this country.

Health status of Asian Pacific Americans in Missouri.

The dramatic increase in Asian Pacific Americans has created a different set of social, economic and health issues for the country as well as for this state. Asian Pacific Americans are extremely heterogeneous and bipolar in socioeconomic status and health issues. Asian Pacific Islander Americans come from over 43 countries and speak over 100 languages and dialects. This study reveals that in this state, 23% of Asian Pacific American households are linguistically isolated. Almost 20% of Asian Pacific American families (married couples with children under 5 years old) have an income below the poverty line. The need for severe mental health service is four times higher for southeast Asian refugees than the overall population. The death rates from communicable disease and suicide are lowest for Asian Pacific Americans, and for Asian Pacific Americans, the age-adjusted death rates are widely different. For example, people with Hawaiian background appear to have a high incidence of death from heart disease (363.3 per 100,000) whereas Chinese experienced a higher incidence of death from cancer (70.2 per 100,000). The Asian Pacific Americans have the lowest infant mortality rate. This paper suggests that providers, educators and legislators should pay more attention to Asian Pacific American communities regarding socioeconomic and health care needs to create a healthy and productive community.

Evaluation of hepatitis B and C viral markers: clinical significance in Asian and Caucasian patients with hepatocellular carcinoma in the United States of America.

In order to evaluate the roles of hepatitis B virus (HBV) and hepatitis C virus (HCV) and their clinical significance in Asian-American and Caucasian patients with hepatocellular carcinoma (HCC) in the USA, 110 HCC patients, seen in a community-based teaching hospital in the Los Angeles area over a 10 year period, were enrolled. Seventy-nine (72%) patients were Asian-American and 31 (28%) were Caucasians. Of the 110 HCC patients, 69 (63%) were positive for serum hepatitis B surface antigen (HBsAg), 26 (24%) were positive for serum antibody to hepatitis C virus (anti-HCV), five (all Asian-Americans) were positive for both markers; 11 (10%) patients had a history of alcoholism. HBsAg was detected in 63 (80%) Asian-American patients, significantly higher than in the six (19%) Caucasian HCC patients (P < 0.01). Anti-HCV was detected in 10 (32%) Caucasian and in 16 (20%) Asian-American HCC patients (P > 0.05). Among Asian-American HCC patients, anti-HCV was more prevalent in those who were HBsAg-negative than in the HBsAg-positive patients (69 vs 8%; P < 0.01). A history of alcoholism was obtained in nine (29%) Caucasian HCC patients, significantly higher than in the two (3%) Asian-American HCC patients (P < 0.05). Comparing HCC patients with positive HBsAg and with anti-HCV, HBsAg-positive HCC patients were younger, Asian-Americans and predominantly male; 38% had a family history of liver disease. In contrast, anti-HCV-positive HCC patients were older by nearly a decade and 46% had a history of blood transfusion. Using a stepwise logistic regression analysis, Asian race and patient age < 50 years were found to be independent predictors for HBsAg-positivity, while a history of blood transfusion was the only predictor for anti-HCV-positivity in HCC patients. There was no significant difference in the rate of cirrhosis, serum levels of alpha-fetoprotein and survival between HBsAg-positive and anti-HCV-positive HCC patients. In conclusion, chronic HBV infection was the major aetiological factor in Asian-American HCC patients, while chronic HCV infection and alcoholism were major aetiological factors in Caucasian HCC patients in the USA.

A profile of six community-based HIV prevention programs targeting Asian and Pacific Islander Americans.

Based on a framework (i.e., research and evaluation, prevention and services, and advocacy and policy), the goal of this article is to profile six community-based HIV prevention programs targeting Asian and Pacific Islander (API) Americans, especially among men who have sex with men. These six programs were chosen based on one or more of the following three criteria: (a) epidemiological profiles of AIDS cases among Asian and Pacific Islander Americans, (b) ethnic diversity, and (b) community development among Asian and Pacific Islander Americans in the fight against HIV. The six programs are (a) the Kokua Kalih Valley Health Center, Honolulu; (b) the Asian and Pacific Islander Wellness Center, San Francisco; (c) the Asian Pacific AIDS Intervention Team, Los Angeles; (d) the Asian and Pacific Islander Coalition on HIV and AIDS, New York City; (e) the AIDS Services in Asian Communities, Philadelphia; and (f) the Massachusetts Asian AIDS Prevention Project, Boston. The present analysis reveals that five programs have their roots in the gay or bisexual communities. Two programs have existed for about 3 years (the epidemic is going into its 17th year). Major financial support for the six programs are federal, state, or county sources; private support is generally minimal. All six programs offer a wide range of culturally competent and linguistically appropriate prevention activities and services (including two national projects) targeting a diverse API population. However, gaps in services exist in the younger programs. In addition to a paucity of epidemiological, surveillance, and empirical data, most reported that barriers fall into one or two interrelated categories: (a) structural (e.g., lack of governmental or private funding) or (b) cultural (e.g., denial of risk, homophobia, fear of confidentiality). These findings suggest that HIV prevention activities and services for Asian and Pacific Islander Americans should be based on empirical and cultural data, and that API Americans should become more actively involved in social and political activities. Asian and Pacific Islander American agencies are challenged to integrate HIV with other health and social issues pertinent to the communities.

Comparison of prevalence and risk factors for microalbuminuria in South Asians and Europeans with type 2 diabetes mellitus.

Although Type 2 (non-insulin-dependent) diabetes mellitus (Type 2 DM) is more common in South Asians than in Europeans in the UK, very little is known about complications and their risk factors in South Asians. We sought microalbuminuria in a cross-sectional study of 583 European and 889 South Asian Type 2 DM clinic attenders to Ealing Hospital, London, over 1 year. Albumin/creatinine ratios were measured in early morning urines. Prevalence of microalbuminuria was greater in South Asians compared to Europeans (40% versus 33% in men, p = 0.003, and 33% versus 19% in women, p < 0.0001). Glycaemic control was worse and prevalence of hypertension, retinopathy and heart disease was higher in South Asians. Key risk factors for microalbuminuria in both ethnic groups were glycaemic control, diabetes duration, blood pressure, triglyceride and retinopathy, but none accounted for the higher microalbuminuria prevalence in South Asians. Age and sex adjusted odds ratio for microalbuminuria was 1.78 (95% CI 1.02, 2.82, p = 0.02) in South Asians versus Europeans. After adjustment for confounders, this became 2.07, 95% CI 1.13, 3.79, p = 0.02. We conclude that microalbuminuria is more common in South Asians with Type 2 DM than in Europeans and, although risk factor relationships appeared similar in both groups, and some risk factors were more prominent in South Asians, this cannot account for the high prevalence of microalbuminuria observed in South Asians.

Impaired fibrinolysis and increased fibrinogen levels in South Asian subjects.

The potential role of haemostatic risk markers is largely unexplored in South Asians, who have increased morbidity and mortality from cardiovascular disease and an increased prevalence of insulin resistance. To investigate differences in thrombotic risk markers between South Asian and White populations, 42 Asian and 50 White males and 96 Asian and 80 White females, clinically free from vascular disease, were recruited. Venous blood samples were taken for measures of haemostasis and determination of blood lipids. South Asian females showed lower fasting blood glucose than White females (4.6 vs. 4.8 mmol/l, P<0.008). In the South Asian population, total cholesterol was lower in females, with a similar trend in males (females 5.0 vs. 5.5 mmol/l, P<0.001; males 5.1 vs. WM 5.5 mmol/l, P=0.09), but no difference in triglyceride levels. South Asian subjects of both genders had markedly higher levels of fibrinogen (females 3.3 vs. 2.8 mg/dl, P<0.0005; males 3.0 vs. 2.5 mg/dl P<0.002) and PAI-1 activity (females 14.6 vs. 8.7 ng/ml, P<0.0005, males 21.3 vs. 12.2 ng/ml, ) P<0.0005). Factor VII:C was lower in both South Asian groups (females 110.9 vs. 122.4%, P<0.005; males 103.3 vs. 125%, P<0.0005). Factor XII was lower in South Asian females and there were no differences in Factor XII levels in male populations. These results suggest that elevated PAI-1 and fibrinogen in Asians of both genders may contribute to the increased vascular risk experienced in this population; however, the role of dyslipidaemia and Factor VII are not clear in these processes.

Plasma 25-hydroxyvitamin D in pregnant Asian women and their babies.

Plasma 25-hydroxyvitamin D (25-OHD) was measured in cord blood taken at delivery and in fasting blood taken from 44 Asian mothers in the first day of the puerperium. Blood was taken from the baby 48 h after delivery. Cord-blood samples were also taken at 43 non-Asian deliveries. Plasma 25-OHD concentrations in Asians were low at delivery; in 81% of the mothers and 36% of the babies plasma 25-OHD was in the osteomalacic range. Asian lower than concentrations in non-Asian controls. 4 Asian babies had vraniotabes and 1 had neonatal tetany. 1 non-Asian baby had craniotabes. A review of 3327 deliveries in 1978 confirmed that neonatal tetany was significantly more common in Asian babies (2.3%) than in non-Asian babies (0.3%). In 44 other Asian mothers supplements of 1000 units of vitamin D daily during pregnancy significantly increased plasma-25-OHD concentrations at delivery.

Hodgkin's disease in Asians: incidence patterns and risk factors in population-based data.

Hodgkin's disease (HD) has been reported to be rare in Asians. Data sparseness has hindered studies exploring the relative contributions of environment and heredity to HD etiology, and individual risk factors have never been studied in an Asian population. With the most recent, uniformly collected population-based data from the US and Asia, we compared HD incidence rates in Chinese, Japanese, Filipinos, and Asian Indians in the US and in Asia. HD incidence rates were quite low in all Asian subgroups, but approximately double in US Asians as in native Asians. In both, rates were lower for Japanese and Chinese than for Filipinos and Asian Indians. A modest young-adult rate peak occurred for most US Asian groups, but not for any population in Asia. In data from a population-based case-control study of HD in San Francisco area women, young-adult Asian cases, like young-adult cases of other racial/ethnic groups, had childhood social environments indicative of less early contact with children. Given environmental and lifestyle differences between the US and Asia, the consistently low rates of HD in Asians suggest genetic resistance to disease development, possibly associated with HLA type. International and inter-ethnic differences, and risk factor patterns in case-control data, implicate environmental influences in the etiology of HD.
