Attitudes to and perceived use of health care services among Asian and non-Asian patients in Leicester.

A random sample of 449 Asian patients and 447 non-Asian patients were interviewed at home in their preferred language using a personally administered questionnaire comparing attitudes to and perceived use of health care services in Leicester. The overall response rate was 89.6%. There were differences in the responses of the Asian and non-Asian populations. With respect to communication, language as a barrier appears to be a diminishing problem among Asian patients in Leicester. However, Asian patients reported finding it more difficult to gain access to their general practitioners than non-Asian patients. More Asian than non-Asian patients would have preferred direct access to consultants and most respondents from both populations felt they should be able to request a hospital opinion from their general practitioner. More Asian patients disliked management of illness by telephone than non-Asian patients, the latter feeling that telephone advice could save them a trip to the surgery, or their general practitioner a home visit. However, both groups regarded home visiting as essential. Asian patients disliked deputizing services more than non-Asian patients, and there was some support for 24 hour surgeries, particularly among the Asian population, with doctors working in shifts. As Asian patients appear to differ from non-Asian patients with respect to attitudes and perceived need for health care services, this type of survey may form the basis for the more rational planning of health care delivery to ethnic minority patients in the future.

Quality of hospital service: a study comparing 'Asian' and 'non-Asian' patients in Middlesbrough.

To compare 'Asian' and 'non-Asian' patients' experience of and satisfaction with non-clinical aspects of their hospital care, and to evaluate the effect of subsequent provision of 'Asian' food, we undertook interview surveys of recently discharged adult patients in Middlesbrough. Fifty-two 'Asians' and 52 'non-Asians' matched for sex, age, specialty of admission and hospital reported similar experiences in regard to the amount of information received, the presence of medical students during examination, and satisfaction with privacy and visiting arrangements. The main differences between the groups related to the receipt of written information in the patients' first language, 'Asian' patients' inability to communicate because of lack of English and their dissatisfaction with existing interpreting arrangements, 'Asian' women's attitudes to examination by male doctors, and provision of and satisfaction with hospital food. For example, 47 (90 per cent) 'Asians' and 14 (27 per cent) 'non-Asians' required a special diet but 19 per cent and 86 per cent, respectively, received it; and 'Asians' were less satisfied with the food overall. Despite being disadvantaged 'Asian' patients seldom complained. Following the provision of 'Asian' food, 'Asian' patients reported satisfaction levels comparable with those of 'non-Asians'. Equitable health care provision for ethnic minorities requires a level of service comparable with that enjoyed by the majority community. Written information in minority languages, professional interpreters, examination of female patients by women doctors and culturally suitable food were confirmed as priority needs. Staff training and community education may ensure successful implementation of policy on health care of ethnic minorities. Finally, the quality of non-clinical care in hospital needs to be raised for all groups of patients.

Insulin resistance, diabetes, and risk markers for ischaemic heart disease in Asian men and non-Asian in Bradford.

OBJECTIVE: To examine the hypothesis, in a community not studied before, that insulin resistance associated with centralised adiposity is the mechanism underlying the predisposition of Asian immigrant communities to both ischaemic heart disease and diabetes mellitus. DESIGN: Cross sectional study within one socioeconomic stratum. SETTING: Two factories in the textile sector in Bradford, West Yorkshire. SUBJECTS: Male manual workers of Asian (110) and non-Asian origin (156) aged 20-65 years. RESULTS: Diabetes was almost three times more prevalent in the Asian group. Two hours after an oral glucose load Asian men had double the serum insulin concentrations of non-Asian men (p < 0.0001). Asian men also had significantly lower concentrations of plasma total cholesterol (p < 0.03), high density lipoprotein cholesterol (HDL) (HDL2, p < 0.0001; HDL3, p < 0.0001), and apolipoprotein AI (p < 0.0001). Fasting plasma triglyceride concentrations were slightly higher (p = 0.072) in the Asian men; thus the ratio of triglyceride cholesterol was higher (p = 0.006). The inter-relation between serum insulin and plasma lipid concentrations indicated metabolic differences between the ethnic groups. Insulin concentrations were associated with cholesterol concentrations in the Asian men only and there was a lack of association between triglyceride, low density lipoprotein cholesterol, and HDL cholesterol in this group. The risk marker profile in the Asian men was therefore quite different to that of their non-Asian counterparts and was associated with a greater tendency to centralised adiposity. CONCLUSION: These data support the insulin resistance hypothesis and thus have important implications for strategies for the prevention of heart disease in Asian communities in the United Kingdom.

A comparative study of hepatitis B viral markers in the family members of Asian and non-Asian patients with hepatitis B surface antigen-positive hepatocellular carcinoma and with chronic hepatitis B infection.

Serologic tests for evidence of hepatitis B virus (HBV) infection were performed on family members of Asian and non-Asian patients with either hepatitis B surface antigen (HBsAg)-positive hepatocellular carcinoma or chronic HBV infection. Asian family members had a significant increase of HBsAg (34% higher) and of antibody to HBsAg or of antibody to hepatitis B core antigen (50% higher) when they were compared with non-Asian family members. In the Asian group, viral markers were detected more frequently in blood relatives than in nonblood relatives of the index cases. Within this group, birthplace did not influence the frequency of antigenemia, since HBsAg was positive in 55 (44%) of 125 Asians born in Asia and in 36 (38%) of the 94 Asians who were born in the United States. Also, HBsAg positivity frequently was seen in offspring from HBsAg-positive carrier mothers as well as from HBsAg-positive carrier fathers whose spouses were either HBsAg-negative or who had antibody. The e antigen was found more often in individuals 30 years of age or younger than in older individuals. This study indicates that intrafamilial spread of HBsAg in Asian families plays an important role in the perpetuation of HBV infection and in the eventual development of chronic liver disease in this ethnic group.

General practitioners' perceptions of Asian and non-Asian patients.

The literature on the health of the population of Asian origin contains little on their interaction with primary care services. This paper reports results of a postal survey of GPs' attitudes towards Asian and Non-Asian patients. The response rate was 78%-141 of the 182 GPs replied. Compared with non-Asian patients, GPs held less positive attitudes towards Asian origin patients who were thought to require longer for consultations, be less compliant, and make excessive and inappropriate use of health services. These perceptions have implications for patient care and the GP workload.

Asians, Asian-Americans and alcohol.

The association of flushing (vasodilation, reddening of the skin) with the alcohol use of Asians and Asian-Americans is examined. Historical changes in alcohol use, recent secular changes in alcohol use, and marked differences in consumption among Asian populations and among Asian-Americans of the same national origins, as well as the lack of reduction of sex differences among flushers, indicate that flushing has little influence on alcohol consumption. Social, psychological, and cultural influences seem to be more adequate explanatory devices with regard to Oriental alcohol use.

Psychiatric education and training of Asian and Asian-American psychiatrists.

The Asian and Asian-American physician in a standard psychiatric residency is faced with discrimination at several levels, as well as special problems of professional role confusion and personal identity, all of which can create barriers to professional development and productivity. Further, most standard psychiatric residencies do not include teaching or supervision specific to treating Asian patients. The author proposes the establishment of a specialized program, focusing on ethnic minority groups, within a general psychiatric residency; he discusses specific features of such a program. This approach may help to alleviate the problem of inadequate resources for handling the mental health problems of Asian-Americans and underutilization of mental health resources by this group.

Quantitation of beta-thalassemia genes in Quebec immigrants of Mediterranean, southeast Asian, and Asian Indian origins.

Beta-thalassemia minor occurs at 5% frequency (on average) in populations migrant (since 1945) from Mediterranean countries to the province of Quebec. Individuals of Southeast Asian/Chinese and Asian Indian origin now living in the province also carry beta-thalassemia genes at similar frequencies. We characterized beta-thalassemia genes on 68 chromosomes (19 patients and 30 carriers identified by screening) to describe heterogeneity of beta-thalassemia alleles and to evaluate desirability of DNA tests in carrier screening. Thirteen different mutations account for 74% of the 68 beta-thalassemia chromosomes: seven occur on Mediterranean chromosomes (IVS I,nt110, Non 39, IVS I,nt6, IVS I,nt1G----A, IVS II,nt1, Fr8, IVS II,nt745) another three on SE Asian chromosomes (Fr 41-42, IVS II,nt654, HbE) and yet another three on Asian Indian chromosomes (IVS I,nt5, 619 bp del, IVS I,nt1G----T). Twenty-six percent (18/68) of the chromosomes carried none of 17 alleles accounting for 92-96% of beta-thalassemia molecular pathology in reference populations. The Italian beta-thalassemia chromosomes in the Quebec sample least resembled those in the corresponding source population. Until the spectrum of mutations in Quebec populations is fully defined, phenotype assay remains the most reliable and efficient method for beta-thalassemia carrier screening.

Commercialization of biotechnology in the Asian region. Report of meeting of Asian Productivity Organization (APO) in Osaka, Japan.

Detailed studies on the commercial development of biotechnology in five countries in the Asian Region (viz. Japan, Korea, Taiwan, Thailand, India) indicate a very significant role played by government in strategic planning and R & D financing. Strong growth is projected in some traditional biotechnology products e.g. amino acids such as monosodium glutamate and L-lysine, animal and human vaccines, and in environmental applications of biotechnology. The cash flow from these products will underpin future development and marketing of diagnostics, anticancer and antiviral drugs, particularly in Japan and Korea.

First myocardial infarctions in Asian and white men.

OBJECTIVE: To compare the presentation and natural course of first myocardial infarctions in immigrant Asians and the indigenous white population in Britain and the subsequent risk states of the two groups. DESIGN: Prospective ethnic comparison of consecutive patients with first myocardial infarctions. SETTING: Secondary referrals to a coronary care unit of a district general hospital. PATIENTS: 128 Men (77 white, 54 Asian) presenting consecutively with a first myocardial infarction diagnosed on the basis of clinical, biochemical, and electrocardiographic findings. END POINT: Identification of mechanisms accounting for the increased rate of ischaemic heart disease in Asians. MEASUREMENTS AND MAIN RESULTS: Infarct size was assessed by measuring the release of creatine phosphokinase (all patients), radionuclide ventriculography (50), and contrast ventriculography (103). Risk states after infarction were assessed from the degree of ventricular dysfunction as determined by exercise electrocardiography (82 patients) and from the extent of coronary atheroma as determined by coronary arteriography (103). Glucose state was measured in fasting venous blood samples. Overall the relative rate of infarction was 4.9 times higher in Asians (95% confidence interval 3.4 to 6.9) than in the white population. Moreover, the relative rate of infarction was higher in Asians in all 10 year age groups, the greatest difference being in 30-39 year olds. The mean age of the Asian denominator population was 47.1 years compared with 49.5 years in the white population. Age at infarction was less in Asians (50.2 years) than in white patients (55.5 years; mean difference 5.5 years (95% confidence interval 2.5 to 7.1]. In Asians the mean creatine phosphokinase activity was 777 (95% confidence interval 155 to 1399) U/1 higher, radionuclide ejection fraction 8.9% (1.0% to 16.9%) lower, and left ventricular fractional shortening 4.8% (1.4% to 8.2%) lower than in white patients. The extent of coronary atheroma was significantly greater in Asians. The mean numbers of plaques in vessels not associated with infarction were 3.66 (median 3.0, range 0-10) in Asians compared with 1.97 (median 2.0, range 0-6) in white patients (p less than 0.001), and a higher proportion of Asians had three vessel coronary artery disease (p less than 0.001). Asians with diabetes or impaired glucose tolerance did not differ from those with normal blood glucose values. CONCLUSIONS: Atherogenesis arises earlier in Asians, contributing to premature first myocardial infarctions. The increased incidence of diabetes in Asians may not in itself be relevant in the greater propensity to coronary atheroma in Asians.

Disturbances of insulin in British Asian and white men surviving myocardial infarction.

OBJECTIVE: To examine the role of insulin as a cardiovascular risk factor in British Asian and white men. DESIGN: Case-controlled study of survivors of first myocardial infarction. SETTING: District general hospital. PATIENTS: Consecutive series of 76 white and 74 Asian men who survived first myocardial infarction compared with 58 white and 61 Asian male controls without coronary artery disease who were randomly sampled from the community. RESULTS: More Asians than white subjects had impaired glucose tolerance or overt diabetes as measured by the two hour glucose tolerance test (23/74 (32%) v 11/76 (15%) (p less than 0.001) among patients; 17/61 (28%) v 3/58 (6%) (p less than 0.001) among controls). Insulin and C peptide concentrations were higher in both patient groups than in respective controls (p less than 0.001) and higher in Asian than in white subjects, irrespective of their glucose tolerance. Triglyceride concentrations were higher in patients than in controls (1.92 (SD 1.05) v 1.43 (0.82) mmol/l among Asian men; 1.65 (0.83) v 1.3 (0.61) mmol/l among white subjects; p less than 0.001). Total cholesterol concentrations were lower in both groups of Asians than in respective white subjects (5.78 (0.99) v 6.22 (1.04) mmol/l (p less than 0.01) among patients; 5.54 (1.01) v 5.65 (1.11) mmol/l (p less than 0.6) among controls). High density lipoprotein cholesterol concentrations were lower in Asian than in white subjects. The ratio of total cholesterol to high density lipoprotein cholesterol was significantly higher (p less than 0.001) in both patient groups (6.69 (1.81) in Asian patients and 6.31 (1.91) in white patients) than in respective controls (5.24 (1.19) and 4.77 (1.43)). Regression analysis identified C peptide concentration and the ratio of total to high density lipoprotein cholesterol as powerful independent predictors of myocardial infarction in Asian and white men. Total cholesterol concentration predicted infarction in white but not in Asian men. CONCLUSIONS: Secretion and hepatic extraction of insulin are high in survivors of myocardial infarction and especially high in British Asians. Tissue resistance to the action of insulin, giving rise to increased pancreatic secretion, may be an important risk factor for coronary artery disease in both ethnic groups and may be partly responsible for the high incidence of diabetes and coronary artery disease in Asian populations.

Does the MRCGP examination discriminate against Asian doctors?

OBJECTIVE: To ascertain whether the membership examination for the Royal College of General Practitioners (MRCGP) discriminates against doctors of Indian subcontinent ethnic origin ("Asian doctors"). DESIGN: Retrospective analysis of data from five administrations of the MRCGP examination (December 1988-December 1990). SETTING: United Kingdom national examination body. SUBJECTS: 3686 doctors taking the examination for the first time, 244 of whom were classified as Asian, the remainder as non-Asian. MAIN OUTCOME MEASURES: Comparison of performance in each of the written and oral components of the examination between Asian doctors, identified by their names and classified into subgroups by countries of birth and primary medical training from data provided at registration, and non-Asian doctors. RESULTS: On written components of the examination (multiple choice paper mean score Asians versus non-Asians 42.3 v 48.6, modified essay paper 40.9 v 48.9, practice topic/critical reading paper 41.5 v 48.7, all p less than 0.001 by t testing). But analysis by countries of birth and primary training showed that these differences were due largely to poor performance by certain groups of Asian doctors, especially those born and trained in the Indian subcontinent or elsewhere outside the United Kingdom. Asian doctors born and trained in the United Kingdom and those born in Africa or the West Indies and trained in the United Kingdom performed similarly to the non-Asian doctors. CONCLUSIONS: The examination does not systematically discriminate against Asian doctors, but the poor performance of the two subgroups of Asians is cause for serious concern and requires investigation.

Incidence of cancer in Bradford Asians.

STUDY OBJECTIVE: The aim of the study was to investigate the incidence of cancer in Asians living in Bradford. DESIGN: Cancer registrations were obtained from the Yorkshire Regional Cancer Registry for the six year period 1979-1984. Registrations relating to persons of Asian background were extracted using forenames and surnames. Data were analysed by disease category and age and sex specific incidence rates were calculated. These were compared with expected incidence rates for the non-Asian population and with rates for the Indian subcontinent derived from the Bombay Cancer Registry. SETTING: Data collection was confined to the Bradford Metropolitan District, population 449,897 (1981). SUBJECTS: The Asians studied originated from Pakistan (65%), India (28%), Bangladesh (4%), and East Africa (3%). The total Asian population of the Bradford Metropolitan District was approximately 45,000. MAIN RESULTS: Over the study period there were 178 Asian cancer registrations. The overall standardised registration ratio was 53.7 for males (100 cases, 95% confidence interval 43-64), and 43.5 for females (78 cases, 95% CI 34-53). The standardised registration ratios for cancer of the hypopharynx in males and gall bladder in females were significantly raised. There was a particularly low incidence of cancer of the stomach, large bowel, lung, skin, and bladder in males, and of skin, breast, cervix (in situ), and ovary in females. The analyses suggested that lung and breast cancer incidence may be increasing towards the non-Asian level. In situ cancer of cervix in Asians shows no evidence of the high rates found in younger non-Asian age groups. CONCLUSIONS: Lower incidence of many cancers in Asians may be due to lower exposure to major risk factors. Demographic change resulting in increased exposure to these risk factors can be expected to result in an increase in cancer incidence in Asians.

The molecular basis of alpha-thalassemias: frequent occurrence of dysfunctional alpha loci among non-Asians with Hb H disease.

Study of Asians has previously indicated that deletion of alpha-globin structural genes is the predominant lesion in alpha-thalassemias and that Hb H disease occurs when three of four normal alpha loci per cell are deleted. To test the generality of this model, Hb H disease DNAs of both Asian and non-Asian origin were analyzed by restriction endonuclease mapping using the technique of Southern (1975). Whereas in normal DNA, alpha sequences are present in a single Eco Rl fragment of cellular DNA approximately 22.5 kb long, fragments of 22.5, 20 and 2.6 kb were found in various Hb H disease DNAs. The 20 kb Eco Rl fragment alone, in which a single alpha-globin structural locus resides, was found in Asian Hb H disease DNA. This finding is consistent with the deletion model of alpha-thalassemia. In contrast, seven of eight non-Asian Hb H disease DNAs displayed a more complex molecular composition. The fragment patterns observed were 22.5 kb alone, 22.5 plus 2.6 kb, 20 plus 2.6 kb and 20 kb alone. Non-Asian Hb H disease DNAs contained one, two or three alpha loci per cell in contrast to the one locus predicted by the simple deletion model of alpha-thalassemia. The data are best explained by the existence of defective alpha loci in certain individuals with alpha-thalassemia, particularly outside the Asian population. Restriction mapping of the 20 kb Eco Rl fragment found in Asian and some non-Asian Hb H disease DNAs demonstrated a striking similarity in the placement of restriction sites about the single alpha gene compared with sites about the two genes in the 22.5 kb Eco Rl fragment seen in normal DNA. These data are consistent with origin of the 20 kb fragment from the 22.5 kb normal Eco Rl fragment by either unequal crossing-over or a deletion event. The molecular heterogeneity and frequent occurrence of defective alpha loci in non-Asian Hb H disease DNAs described here may explain, in part, the clinical heterogeneity of alpha-thalassemias and the absence of the homozygous deletion state (hydrops fetalis) in non-Asians. Further study of cellular DNA fragments containing the defective alpha loci identified in this work may indicate the types of specific mutations responsible for abnormal globin gene expression and complement similar studies on abnormal beta genes in beta-thalassemias.
