Ethnic differences in diabetes, cardiovascular risk factors and health care: the Amsterdam Health Survey of 2004

The prevalence of diabetes in inhabitants of Amsterdam (18 years and older) is 4%. The prevalence of diabetes is three times higher among Turkish people and four times higher among Moroccans in comparison to Dutch people. Turkish diabetes patients have a higher mean body mass index compared to Dutch diabetes patients, but Turkish and Moroccan diabetes patients are admitted to hospital less often than Dutch diabetes patients. It is important for policy makers to know the differences in disease prevalence and health care use between ethnic groups, considering the expected rise in the proportion of immigrants. These results formed contributions to this report that was brought out by the National Institute for Public Health and the Environment and in cooperation with the Amsterdam Health Monitor of the Amsterdam Health Service. Forty-three percent of the 4042 invited Amsterdam inhabitants participated in the study in 2004. Ethnic differences in health and health care use were analyzed for the age group of 18-70 years, standardized for age and gender. Turkish and Moroccan people without diabetes differed from Dutch people without diabetes on many counts. For example, Turkish and Moroccan people were more often overweight and had higher mean blood glucose levels. They visited their general practitioners more often and experienced their own health as being moderate or poor on a more frequent basis. Turkish people without diabetes experienced more serious cardiac problems than Dutch people. The prevalence of cardiovascular risk factors in diabetes patients was high among all ethnic groups. In general, cardiovascular risk factors were more frequent in Turkish diabetes patients, and to a lesser extent in Moroccan diabetes patients, compared to Dutch diabetes patients. Treatment of cardiovascular risk factors in diabetes patients is important for the prevention of or delay in cardiovascular complications.De prevalentie van diabetes bij inwoners van Amsterdam (18 jaar en ouder) wordt geschat op vier procent. Turken en Marokkanen hebben respectievelijk driemaal en viermaal vaker diabetes vergeleken met Nederlanders. Turkse diabeten zijn gemiddeld zwaarder dan Nederlandse diabeten. Turkse en Marokkaanse diabeten worden echter minder vaak opgenomen in een ziekenhuis dan Nederlandse diabeten. Een beschrijving van etniciteitverschillen in het voorkomen van ziekten en zorggebruik is van belang voor het beleid omdat immigranten een steeds groter deel van de bevolking zullen gaan uitmaken. De Amsterdamse Gezondheidsmonitor 2004 is uitgevoerd door de GGD Amsterdam in samenwerking met het RIVM. Drieenveertig procent van 4042 uitgenodigde Amsterdammers (18 jaar en ouder) heeft aan het onderzoek meegedaan. Etnische verschillen in gezondheid en zorg werden geanalyseerd voor de leeftijd 18-70 jaar, gestandaardiseerd naar leeftijd en geslacht. Turken en Marokkanen zonder diabetes verschilden op bijna alle uitkomsten van Nederlanders zonder diabetes. Turken en Marokkanen waren bijvoorbeeld gemiddeld zwaarder dan Nederlanders en zij hadden hogere gemiddelde bloedglucosewaarden. Zij gingen vaker naar de huisarts en waren minder tevreden over de eigen gezondheid. Acht procent van de Turken zonder diabetes heeft ooit een ernstige hartaandoening gehad, dit is bijna viermaal zo vaak als bij Nederlanders zonder diabetes. Risicofactoren voor hart- en vaatziekten kwamen veel voor bij diabeten uit alle etnische groepen. Turkse diabeten, en in mindere mate Marokkaanse diabeten, hadden over het algemeen een ongunstiger risicoprofiel dan Nederlandse diabeten. Behandeling van het risicoprofiel van diabetespatienten is belangrijk om het optreden van complicaties te voorkomen of uit te stellen

Low migrant mortality in Germany for men aged 65 and older: fact or artifact?

Migrant mortality in Europe was found to be lower than mortality of host populations. In Germany, residents with migrant background constitute nearly one tenth of the population aged 65+ with about 40% of them being foreigners. The German Pension Scheme follows vital status of pensioners very accurately. Mortality re-estimation reveals two-fold underestimation of mortality of foreigners due to biased death numerator and population denominator

The effectiveness of "Exercise on Prescription" in stimulating physical activity among women in ethnic minority groups in the Netherlands: protocol for a randomized controlled trial

<p>Abstract</p> <p>Background</p> <p>Lack of physical activity is an important risk factor for overweight, diabetes, cardiovascular disease and other chronic conditions. In the Netherlands, ethnic minority groups are generally less physically active and rate their own health poorer compared to ethnic Dutch. This applies in particular to women. For this reason women from ethnic minority groups are an important target group for interventions to promote physical activity.</p> <p>In the Netherlands, an exercise referral program ("Exercise on Prescription") seems successful in reaching women from ethnic minority groups, in particular because of referral by the general practitioner and because the program fits well with the needs of these women. However, the effect of the intervention on the level of physical activity and related health outcomes has not been formally evaluated within this population. This paper describes the study design for the evaluation of the effect of "Exercise on Prescription" on level of physical activity and related health outcomes.</p> <p>Methods</p> <p>The randomized controlled trial will include 360 inactive women from ethnic minority groups, with the majority having a non-Western background, aged between 18 and 65 years old, with regular visits to their general practitioner. Participants will be recruited at healthcare centres within a deprived neighbourhood in the city of The Hague, the Netherlands.</p> <p>An intervention group of 180 women will participate in an exercise program with weekly exercise sessions during 20 weeks. The control group (n = 180) will be offered care as usual. Measurements will take place at baseline, and after 6 and 12 months. Main outcome measure is minutes of self reported physical activity per week. Secondary outcomes are the mediating motivational factors regarding physical activity, subjective and objective health outcomes (including wellbeing, perceived health, fitness and body size) and use of (primary) health care. Attendance and attrition during the program will be determined.</p> <p>Conclusion</p> <p>This trial will provide information on the effectiveness of an exercise referral scheme on the short and long term among women from ethnic minority groups, mainly non-Western, in the Netherlands. The results of this study will contribute to the evidence base for interventions in ethnic minority populations.</p> <p>Trial registration</p> <p>Dutch Trial register: NTR1294</p

Lifestyle behaviours of young adult survivors of childhood cancer

This cross-sectional study collected baseline data on the health behaviours of a large population of survivors of childhood cancer in the UK, aged 18–30 years, compared with those of sex- and age-matched controls. Data from 178 young adult survivors of childhood cancer, diagnosed and treated at Bristol Children's Hospital, 184 peers from the survivors' GP practices and 67 siblings were collected by postal questionnaire. Conditional logistic regression analysis showed that, for matched sets of survivors and controls, survivors of a variety of childhood cancers reported lower levels of alcohol consumption (P=0.005), lower levels of cigarette smoking (P=0.027) and lower levels of recreational drug use (P=0.001) than controls. Analysis of matched sets of survivors and siblings showed similar trends but no significant differences. A health behaviour index for each participant was constructed from the data collected on five key health behaviours which influence future health status. Comparison of the means for each case group showed that survivors of childhood cancer were leading healthier lives than controls or siblings. This finding was expressed most clearly as the difference in the means of the health behaviour index for each case group, derived from five health behaviours (one-way ANOVA, P<0.001)

Clinical Heterogeneity of Duchenne Muscular Dystrophy (DMD): Definition of Sub-Phenotypes and Predictive Criteria by Long-Term Follow-Up

International audienceBACKGROUND: To explore clinical heterogeneity of Duchenne muscular dystrophy (DMD), viewed as a major obstacle to the interpretation of therapeutic trials METHODOLOGY/PRINCIPAL FINDINGS: A retrospective single institution long-term follow-up study was carried out in DMD patients with both complete lack of muscle dystrophin and genotyping. An exploratory series (series 1) was used to assess phenotypic heterogeneity and to identify early criteria predicting future outcome; it included 75 consecutive steroid-free patients, longitudinally evaluated for motor, respiratory, cardiac and cognitive functions (median follow-up: 10.5 yrs). A validation series (series 2) was used to test robustness of the selected predictive criteria; it included 34 more routinely evaluated patients (age>12 yrs). Multivariate analysis of series 1 classified 70/75 patients into 4 clusters with distinctive intellectual and motor outcomes: A (early infantile DMD, 20%): severe intellectual and motor outcomes; B (classical DMD, 28%): intermediate intellectual and poor motor outcome; C (moderate pure motor DMD, 22%): normal intelligence and delayed motor impairment; and D (severe pure motor DMD, 30%): normal intelligence and poor motor outcome. Group A patients had the most severe respiratory and cardiac involvement. Frequency of mutations upstream to exon 30 increased from group A to D, but genotype/phenotype correlations were restricted to cognition (IQ>71: OR 7.7, 95%CI 1.6-20.4, p6 at 8 yrs" with "normal or borderline mental status" reliably assigned patients to group C (sensitivity: 1, specificity: 0.94). These criteria were also predictive of "early infantile DMD" and "moderate pure motor DMD" in series 2. CONCLUSIONS/SIGNIFICANCE: DMD can be divided into 4 sub-phenotypes differing by severity of muscle and brain dysfunction. Simple early criteria can be used to include patients with similar outcomes in future therapeutic trials

Acculturation and use of health care services by Turkish and Moroccan migrants: a cross-sectional population-based study

<p>Abstract</p> <p>Background</p> <p>There is insufficient empirical evidence which shows if and how there is an interrelation between acculturation and health care utilisation. The present study seeks to establish this evidence within first generation Turkish and Moroccan migrants, two of the largest migrant groups in present-day Western Europe.</p> <p>Methods</p> <p>Data were derived from the Amsterdam Health Monitor 2004, and were complete for 358 Turkish and 288 Moroccan foreign-born migrants. Use of health services (general practitioner, outpatient specialist and health care for mental health problems) was measured by means of self-report. Acculturation was measured by a structured questionnaire grading (i) ethnic self-identification, (ii) social interaction with ethnic Dutch, (iii) communication in Dutch within one's private social network, (iv) emancipation, and (v) cultural orientation towards the public domain.</p> <p>Results</p> <p>Acculturation was hardly associated with the use of general practitioner care. However, in case of higher adaptation to the host culture there was less uptake of outpatient specialist care among Turkish respondents (odds ratio [OR] = 0.90, 95% confidence interval [CI] = 0.82-0.99) and Moroccan male respondents (OR = 0.81, 95% CI = 0.71-0.93). Conversely, there was a higher uptake of mental health care among Turkish men (OR = 0.81, 95% CI = 0.71-0.93) and women (OR = 0.81, 95% CI = 0.71-0.93). Uptake of mental health care among Moroccan respondents again appeared lower (OR = 0.74, 95% CI = 0.55-0.99). Language ability appeared to play a central role in the uptake of health care.</p> <p>Conclusion</p> <p>Some results were in accordance with the popular view that an increased participation in the host society is concomitant to an increased use of health services. However, there was heterogeneity across ethnic and gender groups, and across the domains of acculturation. Language ability appeared to play a central role. Further research needs to explore this heterogeneity into more detail. Also, other cultural and/or contextual aspects that influence the use of health services require further identification.</p

ATM variants and cancer risk in breast cancer patients from Southern Finland

BACKGROUND: Individuals heterozygous for germline ATM mutations have been reported to have an increased risk for breast cancer but the role for ATM genetic variants for breast cancer risk has remained unclear. Recently, a common ATM variant, ATMivs38 -8T>C in cis with the ATMex39 5557G>A (D1853N) variant, was suggested to associate with bilateral breast cancer among familial breast cancer patients from Northern Finland. We have here evaluated the 5557G>A and ivs38-8T>C variants in an extensive case-control association analysis. We also aimed to investigate whether there are other ATM mutations or variants contributing to breast cancer risk in our population. METHODS: Two common ATM variants, 5557G>A and ivs38-8T>C, previously suggested to associate with bilateral breast cancer, were genotyped in an extensive set of 786 familial and 884 unselected breast cancer cases as well as 708 healthy controls. We also screened the entire coding region and exon-intron boundaries of the ATM gene in 47 familial breast cancer patients and constructed haplotypes of the patients. The identified variants were also evaluated for increased breast cancer risk among additional breast cancer cases and controls. RESULTS: Neither of the two common variants, 5557G>A and ivs38-8T>C, nor any haplotype containing them, was significantly associated with breast cancer risk, bilateral breast cancer or multiple primary cancers in any of the patient groups or subgoups. Three rare missense alterations and one intronic change were each found in only one patient of over 250 familial patients studied and not among controls. The fourth missense alteration studied further was found with closely similar frequencies in over 600 familial cases and controls. CONCLUSION: Altogether, our results suggest very minor effect, if any, of ATM genetic variants on familial breast cancer in Southern Finland. Our results do not support association of the 5557G>A or ivs38-8T>C variant with increased breast cancer risk or with bilateral breast cancer

Social inequalities in changes in health-related behaviour among Slovak adolescents aged between 15 and 19: A longitudinal study

<p>Abstract</p> <p>Background</p> <p>Lower socioeconomic position is generally associated with higher rates of smoking and alcohol consumption and lower levels of physical activity. Health-related behaviour is usually established during late childhood and adolescence. The aim of this study is to explore changes in health-related behaviour in a cohort of adolescents aged between 15 and 19, overall and by socioeconomic position.</p> <p>Methods</p> <p>The sample consisted of 844 first-year students (42.8% males, baseline in 1998 – mean age 14.9, follow-up in 2002 – mean age 18.8) from 31 secondary schools located in Kosice, Slovakia. This study focuses on changes in adolescents' smoking, alcohol use, experience with marijuana and lack of physical exercise with regard to their socioeconomic position. Four indicators of socioeconomic position were used – adolescents' current education level and employment status, and the highest education level and highest occupational status of their parents. We first made cross tabulations of HRB with these four indicators, using McNemar's test to assess differences. Next, we used logistic regression to assess adjusted associations, using likelihood ratio tests to assess statistical significance.</p> <p>Results</p> <p>Statistically significant increases were found in all health-related behaviours. Among males, the most obvious socioeconomic gradient was found in smoking, both at age 15 and at 19. Variations in socioeconomic differences in health-related behaviour were more apparent among females. Although at age 15, almost no socioeconomic differences in health-related behaviour were found, at age 19 differences were found for almost all socioeconomic indicators. Among males, only traditional socioeconomic gradients were found (the lower the socioeconomic position, the higher the prevalence of potentially harmful health-related behaviour), while among females reverse socioeconomic gradients were also found.</p> <p>Conclusion</p> <p>We confirmed an increase in unhealthy health-related behaviour during adolescence. This increase was related to socioeconomic position, and was more apparent in females.</p
