Behaviours and expectations in relation to sexual intercourse among 18-20 year old Asians and non-Asians.
(1/114)
OBJECTIVES: To begin to map the reported behaviours and attitudes of young Britons of south Asian origin that may have implications for sexual health. "South Asian" refers to people able to trace their ancestry from the Indian subcontinent (that is, India, Pakistan, and Bangladesh), henceforth referred to as "Asian". DESIGN: A cross sectional study of sexual behaviour using self report measures in a self complete section of a social survey administered by trained interviewers in 1996. SETTING: Greater Glasgow, Scotland. SUBJECTS: Sample (n = 824) originally recruited aged 14-15 in 1992 in secondary schools in Greater Glasgow and subsequently traced through general practitioner registration for 1996 survey. 492 Asians and non-Asians aged 18-20 years old eventually interviewed in their own homes. MAIN OUTCOME MEASURES: Self reported experience of sexual intercourse, age at first intercourse, and contraceptive practice over year before interview. METHODS: Measures of sexual behaviour and attitudes were elicited through a self complete questionnaire filled out in the presence of, and returned to, a trained social interviewer. RESULTS: Asians, and particularly Asian women, were far less likely to report having had heterosexual intercourse. Those Asian women who had had intercourse were likely to do so for the first time at an older age, and with an older partner, than the non-Asian women. Asian women were less likely to report using the pill than non-Asian women, irrespective of their marital status, and Asian men were less likely than non-Asian men to report using condoms. Asian sexual abstinence was reported to be for religious reasons, which were not important for non-Asians. In contrast with non-Asians, Asians saw themselves as likely to be married with children within the next 5 years. Asian men considered the ideal age to marry for men and women to be younger than the non-Asian men's average estimate. Asian and non-Asian women suggested a similar ideal age for men to marry, but Asian women considered a younger age appropriate for women than did non-Asian women. CONCLUSIONS: The higher level of sexual abstinence among Asians, and particularly women, has implications for the delivery of sexual health services to the minority who are sexually active before marriage. The underreporting of condom use by Asian men compared with their non-Asian counterparts, suggests a failure of the existing sexual health education and health services to reach minority ethnic young men which may be remedied by collaborative work with institutions currently used by the Asian community.

Do Indo-Asians have smaller coronary arteries?
(2/114)
There is a widespread belief that coronary arteries are smaller in Indo-Asians. The aim of the present study was to compare the size of atheroma-free proximal and distal epicardial coronary arteries of Indo-Asians and Caucasians. We analysed normal coronary angiograms from 77 Caucasians and 39 Indo-Asians. The two groups were comparable for dominance of the coronary arteries. Indo-Asian patients had generally smaller coronary arteries, with a statistically significant difference in the mean diameters of the left main coronary artery, proximal, mid and left anterior descending, and proximal and distal right coronary artery segments. There was a non-significant trend towards smaller coronary artery segment diameters for the distal left anterior descending, proximal and distal circumflex, and obtuse marginal artery segments. However, after correction for body surface area, none of these differences in size were statistically significant. Thus, the smaller coronary arteries in Indo-Asian patients were explained by body size alone and were not due to ethnic origin per se. This finding nevertheless has important therapeutic implications, since smaller coronary arteries may give rise to technical difficulties during bypass graft and intervention procedures such as percutaneous transluminal coronary angioplasty, stents and atherectomy. On smaller arteries, atheroma may also give an impression of more severe disease than on larger diameter arteries. (+info)
Progress toward poliomyelitis eradication--South-East Asia Region, 1998-1999.
(3/114)
In 1988, the World Health Assembly resolved to eradicate poliomyelitis by the end of 2000 (1). To achieve this goal, the 10 member countries of the World Health Organization (WHO) South-East Asia Region (SEAR) began implementing polio eradication strategies in 1994. In 1999, most polio cases worldwide were reported in SEAR (i.e., 48% of reported polio cases and 62% of cases with wild poliovirus isolation) (2,3). This report summarizes progress in achieving high routine and supplemental vaccination coverage, the surveillance of cases of acute flaccid paralysis (AFP), and the impact of these activities on polio eradication in the region during 1998-1999.

Y-chromosome lineages trace diffusion of people and languages in southwestern Asia.
(4/114)
The origins and dispersal of farming and pastoral nomadism in southwestern Asia are complex, and there is controversy about whether they were associated with cultural transmission or demic diffusion. In addition, the spread of these technological innovations has been associated with the dispersal of Dravidian and Indo-Iranian languages in southwestern Asia. Here we present genetic evidence for the occurrence of two major population movements, supporting a model of demic diffusion of early farmers from southwestern Iran-and of pastoral nomads from western and central Asia-into India, associated with Dravidian and Indo-European-language dispersals, respectively.

A signal, from human mtDNA, of postglacial recolonization in Europe.
(5/114)
Mitochondrial HVS-I sequences from 10,365 subjects belonging to 56 populations/geographical regions of western Eurasia and northern Africa were first surveyed for the presence of the T-->C transition at nucleotide position 16298, a mutation which has previously been shown to characterize haplogroup V mtDNAs. All mtDNAs with this mutation were then screened for a number of diagnostic RFLP sites, revealing two major subsets of mtDNAs. One is haplogroup V proper, and the other has been termed "pre*V," since it predates V phylogenetically. The rather uncommon pre*V tends to be scattered throughout Europe (and northwestern Africa), whereas V attains two peaks of frequency: one situated in southwestern Europe and one in the Saami of northern Scandinavia. Geographical distributions and ages support the scenario that pre*V originated in Europe before the Last Glacial Maximum (LGM), whereas the more recently derived haplogroup V arose in a southwestern European refugium soon after the LGM. The arrival of V in eastern/central Europe, however, occurred much later, possibly with (post-)Neolithic contacts. The distribution of haplogroup V mtDNAs in modern European populations would thus, at least in part, reflect the pattern of postglacial human recolonization from that refugium, affecting even the Saami. Overall, the present study shows that the dissection of mtDNA variation into small and well-defined evolutionary units is an essential step in the identification of spatial frequency patterns. Mass screening of a few markers identified using complete mtDNA sequences promises to be an efficient strategy for inferring features of human prehistory. (+info)
Development of guidelines to facilitate improved support of South Asian carers by primary health care teams.
(6/114)
BACKGROUND: Evidence based guidelines are regarded as an appropriate basis for providing effective health care, but few guidelines incorporate the views of users such as carers. AIM: To develop guidelines to assist primary health care teams (PHCTs) in their work with carers within South Asian communities. METHODS: The guidelines were drawn up by a development group consisting of members of teams in areas with South Asian communities (Leicester and Bradford). The teams were invited to make their recommendations based on a systematic review of literature on minority ethnic carers and the findings of a study of the needs and experiences of local South Asian carers. A grading system was devised to enable the teams and a group of expert peer reviewers to assess the quality of evidence in support of each recommendation. RESULTS: The teams agreed seven recommendations, graded according to available evidence and strength of opinion. External peer review supported the PHCTs' interpretation of evidence and their recommendations. The recommendations included consideration of communication and information for carers, coordination of care within teams, and recognition by team members of the roles of carers and their cultural and religious beliefs. CONCLUSION: There are particular steps that PHCTs can take to improve their support of South Asian carers. It is possible to develop guidelines that take users' views into account and incorporate evidence from qualitative studies. (+info)
Perceptions of vocational trainees on gender and racial disadvantage within the Thames vocational training programme.
(7/114)
BACKGROUND: A recent report has suggested that vocational trainees within London experienced racial or gender disadvantage during their selection. This exploratory study did not investigate the extent or the nature of this disadvantage. AIM: To undertake a survey using a pre-tested questionnaire with dental vocational trainees on the Thames Scheme. The questionnaire explored perceived and experienced aspects of gender and racial disadvantage during their vocational training programme. RESULTS: 127 trainees completed the questionnaire (response rate 92%). Minority ethnic respondents were more than twice as likely to feel their selection was influenced by gender (odds ratio [OR] 2.25, 95% Confidence Interval [CI] 1.02, 5.10) and more than three times likely to feel selection was influenced by their race when compared with their white colleagues (OR 3.05, 95%; CI 1.01,11.45). The majority of trainees did not perceive any disadvantage whilst on the vocational training course. For example, only five respondents (4%) felt that minority ethnic individuals were treated less favourably during the vocational training course. CONCLUSION: In conclusion, this preliminary study has attempted to explore inter-ethnic differences within the profession on perceived racial disadvantage and possible strategies for change. It is clear that the perception of disadvantage is greater than the reality within the experience of most trainees. (+info)
DNA sequence variability of IGHG3 alleles associated to the main G3m haplotypes in human populations.
(8/114)
The present study investigates the molecular basis of the G3m polymorphism expressed by the heavy constant domains of human immunoglobulins gamma 3 chains. By using a new protocol allowing the specific cloning of IGHG3 genes, a total of 51 full-length IGHG3 genomic sequences (about 2 kb) isolated from African, Siberian, West Asian and European population samples were sequenced. IGHG3 sequences were assigned precise G3m haplotypes on the basis of specific associations between G3m allotypes and IGHG3 RFLPs. Specific DNA substitutions involved in the expression of G3m(5), G3m(6), G3m(15), G3m(16), G3m(21), G3m(24) and G3m(28) allotypes were then deduced, elucidating almost completely the determination of the G3m polymorphism at the DNA level. The molecular evolution of G3m haplotypes was investigated by a maximum likelihood phylogeny of IGHG3 sequences. Sequence clusters are shown to be G3m haplotype-specific, corroborating the Gm molecular model deduced from serology, and showing that populations differentiation is much more recent than G3m haplotypes differentiation. The widely distributed G3m(5,10,11,13,14) haplotype is likely to be ancestral to the other G3m haplotypes presently found at high frequencies in different continental areas. (+info)
