RESUMO
BACKGROUND AND AIMS: Evidence shows that migrant children have a higher risk of developing obesity than those with native parents. We aimed to investigate the association between parental migration background and cardiometabolic health in children and adolescents in Europe. METHODS AND RESULTS: We included 8745 children aged 2-17 from the second follow-up of the European IDEFICS/I.Family cohort. Linear regression models were used to investigate the association between parental migration background (one or two migrant parent(s) vs native parents) and body mass index (BMI), metabolic syndrome (MetS) score and its individual components. Outcome variables were parametrized as age and sex-specific z-scores. We adjusted for age, sex, country, and parental education, and additionally for parental income, lifestyle including dietary factors, and maternal BMI. On average, children with two migrant parents had higher z-scores of BMI (+0.24 standard deviation (SD)) and MetS score (+0.30 SD) compared to those with native parents, whereas no significant differences were seen for children with one migrant parent. Associations were attenuated when controlling for maternal BMI and sports club activity. Parental education modified the associations with BMI and MetS z-scores such that they were more pronounced in children with low parental education. CONCLUSION: Children with two migrant parents were at higher risk for adverse cardiometabolic health compared to children with native parents, especially in families with low parental education. These associations were explained by lower physical activity and maternal body weight and encourages early intervention strategies by schools and communities.

BACKGROUND: The government-subsidized health insurance scheme Seguro Integral de Salud ("SIS") was introduced in Peru initially to provide coverage to uninsured and poor pregnant women and children under five years old and was later extended to cover all uninsured members of the population following the Peruvian Plan Esencial de Aseguramiento Universal - "PEAS" (Essential UHC Package). Our study aimed to analyze the extent to which the introduction of SIS has increased equity in access and quality by comparing the utilization of maternal healthcare services among women with different insurance coverages. METHODS: Relying on the 2021 round of the nationally-representative survey "ENDES" (Encuesta Nacional Demográfica y de Salud Familiar), we analyzed data for 19,181 women aged 15-49 with a history of pregnancy in the five years preceding the survey date. We used a series of logistic regressions to explore the association between health insurance coverage (defined as No Insurance, SIS, or Standard Insurance) and a series of outcome variables measuring access to and quality of all services along the available maternal healthcare continuum. RESULTS: Only 46.5% of women across all insurance schemes reported having accessed effective ANC prevention. Findings from the adjusted logistic regression confirmed that insured women were more likely to have accessed ANC services compared with uninsured women. Our findings indicate that women in the "SIS" group were more likely to have accessed six ANC visits (aOR = 1.40; 95% CI 1.14-1.73) as well as effective ANC prevention (aOR = 1.32; 95% CI 1.17-1.48), ANC education (aOR = 1.59; 95% CI 1.41-1.80) and ANC screening (aOR = 1.46; 95% CI 1.27-1.69) during pregnancy, compared with women in the "Standard Insurance" group [aOR = 1.35 (95% CI 1.13-1.62), 1.22 (95% CI 1.04-1.42), 1.34 (95% CI 1.18-1.51) and 1.31(95% CI 1.15-1.49)] respectively. In addition, women in the "Standard Insurance" group were more likely to have received skilled attendance at birth (aOR = 2.17, 95% CI 1.33-3.55) compared with the women in the "SIS" insurance group (aOR = 2.12; 95% CI 1.41-3.17). CONCLUSIONS: Our findings indicate the persistence of inequities in access to maternal healthcare services that manifest themselves not only in the reduced utilization among the uninsured, but also in the lower quality of service coverage that uninsured women received compared with women insured under "Standard Insurance" or "SIS". Further policy reforms are needed both to expand insurance coverage and to ensure that all women receive the same access to care irrespective of their specific insurance coverage.

Background: Chordomas have a high risk of recurrence. Radiotherapy (RT) is required as adjuvant therapy after resection. Sufficient radiation doses for local control (LC) can be achieved using either particle therapy, if this technology is available and feasible, or intensity-modulated radiotherapy. Materials and methods: 57 patients (age, 11.8-81.6 years) with chordomas of the skull base, spine and pelvis who received photon radiotherapy between 1995 and 2017 were enrolled in the study. Patients were treated at the time of initial diagnosis (68.4%) or during recurrence (31.6%). 44 patients received adjuvant radiotherapy and 13 received definitive radiotherapy. The median total dose to the physical target volume was 70 Gy equivalent dose in 2 Gy fractions (EQD2) (range: 54.7-82.5) in 22-36 fractions. Results: LC was 76.4%, 58.4%, 46.7% and 39.9% and overall survival (OS) was 98.3%, 89%, 76.9% and 47.9% after 1, 3, 5 and 10 years, respectively, with a median follow-up period of 6.5 years (range, 0.5-24.3 years). Age, dose and treatment concept (post-operative or definitive) were significant prognostic factors for OS. Primary treatment, macroscopic tumour at RT and size of the irradiated volume were statistically significant prognostic factors for LC. Conclusion: Photon treatment is a safe and effective treatment for chordomas if no particle therapy is available. The best results can be achieved against primary tumours if the application of curative doses is possible due to organs at risk in direct proximity. We recommend high-dose radiotherapy, regardless of the resection status, as part of the initial treatment of chordoma, using the high conformal radiation technique if particle therapy is not feasible.
RESUMO
OBJECTIVES: Cervical cancer still poses a considerable threat to women in low- and middle-income countries, particularly on the African continent. Self-collection of a vaginal sample promises advantages over the established sampling by clinicians. We aimed to assess the accuracy of self-sampling compared to clinician sampling in order to inform its application in primary care in the African context. METHODS: We searched Pubmed, Livivo, Web of Science, Cochrane Library and African Index Medicus on the 07th of February 2022. The eligibility criteria were: reporting (i) self-sampling against clinician-sampling, (ii) study location in Africa, (iii) relevant outcome-measures: (a) Cohen's kappa (b) sensitivity and specificity of self-sampling tests. We combined Cohen's kappa effects, additionally sensitivity and specificity estimates using random-effects models. The study is registered with PROSPERO (CRD42020218081). RESULTS: We included 28 studies in the systematic review and 21 studies in the meta-analysis. Self-sampling was used to test for high-risk HPV infections. Two studies additionally tested for low-risk HPV infections. The pooled Cohen's kappa was 0.66 (95%CI: 0.61-0.71). Populations at risk yielded 0.63 (95%CI: 0.56-0.71). Target amplification tests based on PCR performed best with a kappa of 0.68 (95%CI: 0.63-0.73) compared to isothermal mRNA tests, 0.61 (95%CI: 0.51-0.71). Point of care tests performed exceptionally well, 0.73 (95%CI: 0.67-0.80). Sensitivities are close to 80% and specificities close to 90% of self-sampling to detect high-risk HPV. CONCLUSIONS: Self-sampling agrees moderately to substantially with clinician sampling in the African context. Point of care tests might be particularly suited for application in cervical cancer primary screening in low- and middle-income countries. Populations at risk should get special attention while using self-sampling. Screening protocols should be established.

BACKGROUND: The COVID-19 pandemic and its collateral damage severely impact health systems globally and risk to worsen the malaria situation in endemic countries. Malaria is a leading cause of morbidity and mortality in Ghana. This study aims to describe the potential effects of the COVID-19 pandemic on malaria cases observed in health facilities in the Northern Region of Ghana. METHODS: Monthly routine data from the District Health Information Management System II (DHIMS2) of the Northern Region of Ghana were analysed. Overall outpatient department visits (OPD) and malaria case rates from the years 2015-2019 were compared to the corresponding data of the year 2020. RESULTS: Compared to the corresponding periods of the years 2015-2019, overall visits and malaria cases in paediatric and adult OPDs in northern Ghana decreased in March and April 2020, when major movement and social restrictions were implemented in response to the pandemic. Cases slightly rebounded afterwards in 2020, but stayed below the average of the previous years. Malaria data from inpatient departments showed a similar but more pronounced trend when compared to OPDs. In pregnant women, however, malaria cases in OPDs increased after the first COVID-19 wave. CONCLUSIONS: The findings from this study show that the COVID-19 pandemic affects the malaria burden in health facilities of northern Ghana, with declines in inpatient and outpatient rates except for pregnant women. They may have experienced reduced access to insecticide-treated nets and intermittent preventive malaria treatment in pregnancy, resulting in subsequent higher malaria morbidity. Further data, particularly from community-based studies and ideally complemented by qualitative research, are needed to fully determine the impact of the pandemic on the malaria situation in Africa.

Exposure to second-hand smoke (SHS) is an important public health problem. We assessed SHS exposure in restaurants and bars across the European Union (EU) and studied associations with country-level smoke-free legislation. Data of Eurobarometer surveys 2014 and 2017 were used to estimate country-specific prevalence of observing smoking in restaurants and bars, which can be considered a marker of SHS exposure. Additionally, we used multilevel logistic regression models to study associations with comprehensiveness of national smoke-free regulations in restaurants and bars, which were derived from the Tobacco Control Scale. In total, 44,809 people from all 28 EU member states were included in the analysis. The results of the multilevel logistic analysis show that in countries with complete and extensive bans, respondents were less likely to have observed people smoking inside restaurants than in countries with partial bans, which represented the lowest level of smoke-free policy implementation (OR 0.24, 95%CI 0.10-0.57 for complete ban and OR 0.23, 95%CI 0.10-0.54 for incomplete but extensive ban). Also, the prevalence of seeing people smoking in a bar was lower in the countries with an extensive ban (OR 0.23 95%CI 0.11-0.45) and with a complete ban (OR 0.20 95%CI 0.10-0.40). Between 2014 and 2017, SHS exposure in restaurants and bars decreased significantly. Our results confirm that in countries with extensive or complete smoking bans, people were less exposed to SHS in restaurants and bars; and that partial bans are less effective in reducing SHS exposure.

Tobacco cessation is a key component of WHO's Framework Convention on Tobacco Control. However, success rates decline significantly from intending to quit tobacco, through attempting and becoming a successful quitter. Among Indian adults, the prevalence of smoking and smokeless tobacco use was 10.7% and 21.4% respectively in 2016. Furthermore, 9% of all deaths were estimated to be attributable to tobacco. This study aims to explore associations of socio-demographic, environmental and behavioural dimensions of tobacco users with the process of successful quitting. Multivariable logistic regression analyses were conducted to study (i) attempting to quit and (ii) being a successful quitter for smoked and smokeless tobacco, using cross-sectional Global Adult Tobacco Survey (GATS) datasets for India (2009-10 and 2016-17), where data was pooled from the two surveys (n = 53,463). Advise to quit by health care provider was associated with quit attempts of smoking (1.82, 95% CI: [1.51; 2.20]), and smokeless tobacco (1.71, 95% CI: [1.45; 2.01]). Never being exposed to smoke at home was the strongest environmental factor for successful smoking cessation (4.04, 95% CI: [2.59; 6.31]). Noticing label warnings and advertisements was also associated with attempting to quit smoked and smokeless tobacco. Being a former smoker/smokeless tobacco user was positively connected with attempting to quit the current use of the other tobacco form. We recommend strategies to promote smoke-free homes, and incorporating 'tobacco cessation advocacy' into the curriculum of health care workers. Strengthening the tobacco control law and program promulgated in India since 2003 and its implementation would significantly promote tobacco cessation.

INTRODUCTION: Georgia, like other Eastern European countries, showed a dramatic increase of international labour emigration after becoming independent in 1991. The collapse of the Soviet Union caused economic instability, unemployment and poverty resulting in labour migration. Since then, thousands of children have been left behind in the care of extended family members while their parents work abroad. The aim of this study is to explore schoolteachers' perceptions on parental migration and left-behind children (LBC) in Georgia as schoolteachers are the main contact persons for LBC and their caregivers. METHODS: We conducted six focus-group discussions with public school teachers, namely class-tutors and six in-depth interviews with school principals from two migrant sending regions. We applied reflexive thematic analysis to systematically analyse the data and identify main and sub-themes. The contextual model of family stress underpins this study. RESULTS: We identified the following themes expressed by both, teachers, and school principals: social and economic impact of migrant labour and relationships between schools and migrant families. School teachers and principals acknowledged some positive aspects of migrant labour, but primarily perceived parental migration as a negative experience for children leading to problems in mental health, well-being, and academic performance. Structural factors, lack of support and lack of community involvement were expressed to further worsen the situation. Teachers saw themselves as one of the main supporters for LBC while they described the role of caregivers ranging from caring to unhelpful or even destructive. School principals stated mitigating the situation by regular meetings with class tutors, extra-tutoring for LBC, psychological counselling, and developing/enacting internal guidelines. CONCLUSIONS: Our findings suggest that LBCs and transnational families could benefit from the provision of psychological services at schools.

BACKGROUND: In recent years, there has been greater recognition of the important role of community health volunteers in many countries and their important role informs many health programs. This include health education, provision of services such as screening, monitoring and referral to health facilities. Their roles are better understood in the areas of communicable diseases like HIV infection, Tuberculosis and Malaria however little is known about their role in non-communicable diseases. This study seeks to explore perception of CHVs' functions, tasks, and their fulfilment in identifying people with elevated blood pressure for diagnosis and monitoring of hypertension in Lilongwe, Malawi. METHODS: This was a qualitative naturalistic research design utilizing observation and semi-structured interviews with community health volunteers working in Lilongwe, Malawi. Interviews were carried out with the researcher. Participants were recruited from the ZaMaC project. An interview guide was developed with a category-guided deductive approach. The interviews were recorded through note taking. Data analysis was performed using content analysis approach. RESULTS: Community health volunteers have multiple roles in prevention and monitoring of hypertension. They act as health educators and provide lifestyle counselling. They screened for hypertension and monitored blood pressure and assisted community members to navigate the health system such as linkage to health facilities. These roles were shaped in response to community needs. CONCLUSION: This study indicates the complexities of the roles of community health volunteer in identifying people with elevated BP for diagnosis and monitoring of hypertension. Understanding community health volunteers' roles provides insight into their required competencies in provision of their daily activities as well as required training to fill in their knowledge gaps.

OBJECTIVE: Non-communicable diseases are rapidly becoming one of the leading causes of morbidity and mortality in sub-Saharan Africa. Yet, little is known about patterns of healthcare seeking among people with chronic conditions in these settings. We aimed to explore determinants of healthcare seeking among people who reported at least one chronic condition in rural Burkina Faso. METHODS: Data were drawn from a cross-sectional population-based survey conducted across 24 districts on 52 562 individuals from March to June 2017. We used multinomial logistic regression to assess factors associated with seeking care at a formal provider (facility-based care) or at an informal provider (home and traditional treatment) compared to no care. RESULTS: 1124 individuals (2% of all respondents) reported at least one chronic condition. Among those, 22.8% reported formal care use, 10.6% informal care use, and 66.6% no care. The presence of other household members reporting a chronic condition (RRR = 0.57, 95%-CI [0.39, 0.82]) was negatively associated with seeking formal care. Wealthier households (RRR = 2.14, 95%-CI [1.26, 3.64]), perceived illness severity (RRR = 3.23, 95%-CI [2.22, 4.70]) and suffering from major chronic conditions (RRR = 1.54, 95%-CI [1.13, 2.11]) were positively associated with seeking formal care. CONCLUSION: Only a minority of individuals with chronic conditions sought formal care, with important differences due to socio-economic status. Policies and interventions aimed at increasing the availability and affordability of services for early detection and management in peripheral settings should be prioritised.
OBJECTIF: Les maladies non transmissibles deviennent rapidement l'une des principales causes de morbidité et de mortalité en Afrique subsaharienne. Pourtant, on en sait peu sur les profils de recherche de soins de santé chez les personnes atteintes de maladies chroniques dans ces milieux. Nous visions à explorer les déterminants de la recherche de soins de santé chez les personnes qui ont déclaré au moins une maladie chronique dans les régions rurales du Burkina Faso. MÉTHODES: Les données ont été tirées d'une enquête transversale de population menée dans 24 districts auprès de 52.562 personnes de mars à juin 2017. Nous avons utilisé une régression logistique multinomiale pour évaluer les facteurs associés à la recherche de soins chez un prestataire formels (soins en établissement) ou chez un prestataire informel (traitement à domicile et traditionnel) par rapport à l'absence de soins. RÉSULTATS: 1.124 personnes (2% de tous les répondants) ont déclaré au moins une maladie chronique. Parmi ceux-ci, 22,8% ont déclaré avoir recours à des soins formels, 10,6% à des soins informels et 66,6% à aucun soin. La présence d'autres membres du ménage déclarant une maladie chronique (RRR = 0,57, IC95%: 0,39, 0,82) était associée négativement à la recherche de soins formels. Les ménages plus riches (RRR = 2,14; IC95%: 1,26-3,64), la sévérité perçue de la maladie (RRR = 3,23 ; IC95%: 2,22-4,70) et souffrir de maladies chroniques majeures (RRR = 1,54 ; IC95%: 1,13-2,11) étaient positivement associés à la recherche de soins formels. CONCLUSION: Seule une minorité de personnes atteintes de maladies chroniques ont recherché des soins formels, avec des différences importantes en raison du statut socioéconomique. Les politiques et interventions visant à accroître la disponibilité et l'accessibilité des services de détection précoce et de prise en charge dans les régions périphériques doivent être prioritaires.

BACKGROUND: Like many other Latin America- and Caribbean countries, Peru has introduced a tax-financed health insurance scheme called "Sistema Integral de Salud (SIS)" to foster progress towards Universal Health Coverage. The scheme explicitly targets the poorest sections of the population. Our study explores levels of health insurance coverage and their determinants among Peruvian women following the introduction of SIS. We wish to determine the extent to which the introduction of SIS has effectively closed gaps in insurance coverage and for whom. METHODS: Relying on the 2017 round of ENDES (Encuesta Nacional Demográfica y de Salud Familiar) survey, we analyzed data for 33,168 women aged 15-49. We used multinomial logistic regression to explore the association between health insurance coverage (defined as No Insurance, SIS, Standard Insurance) and women's socio-demographic and economic characteristics. RESULTS: Out of the 33,168 women, 25.3% did not have any insurance coverage, 45.5% were covered by SIS and 29.2% were covered by a Standard Insurance scheme. Women in the SIS group were found to have lower educational levels, live in rural areas and more likely to be poorer. Women in the Standard insurance group were found to be more educated, more likely to be "Spanish", and to be wealthier. Most uninsured women appeared to belong to a middle class, not poor enough to be eligible for SIS, but also not eligible for standard insurance. CONCLUSIONS: Our study confirms that SIS has been effective in increasing coverage among vulnerable women, with coverage rates comparable with those observed among men. Nevertheless, on its own, it has proven to be insufficient to ensure universal coverage among women. Further reforms are needed to ensure that coverage is extended to all population groups.

BACKGROUND: European studies showed that women with a migration background are less likely to participate in mammography screenings than autochthonous women. However, the participation in the German mammography screening programme (MSP) among ethnic German migrants from countries of the former Soviet Union (called resettlers) is unclear so far. The aim of this study was to identify possible differences regarding MSP participation between resettlers from the FSU and the general German population. METHODS: Data from two independent, complementary studies from North Rhine-Westphalia, Germany (a retrospective cohort study 1994-2013; a cross-sectional study 2013/14) were used for comparisons between resettlers and the general population: Odds Ratios (ORs) for MSP participation utilizing the cross-sectional data and time trends of breast cancer incidence rates as well as Chi-Square tests for breast cancer stages utilizing the cohort data. RESULTS: Resettlers showed higher Odds to participate in the MSP than the general population (OR 2.42, 95% CI 1.08-5.42). Among resettlers, a large increase in incidence rates was observed during the MSP implementation (2005-2009), resulting in stable and comparable incidence rates after the implementation. Furthermore, pre-MSP implementation, the proportion of advanced breast cancer stages was higher among resettlers than in the German population, post-MSP implementation the proportion was comparable. CONCLUSIONS: MSP participating seems surprisingly high among resettlers. An explanation for the increased willingness to participate might be the structured invitation procedure of the MSP. However, the exact reasons remain unclear and future research is needed to confirm this hypothesis and rule out the possibility of selection bias in the cross-sectional study.

BACKGROUND: Few studies compared cancer incidence among migrants both to their host countries and to their population of origin. We aimed to compare cancer incidence of ethnic Germans who migrated from the former Soviet Union to Germany (resettlers) to those living in Russia as well as to the German and the Russian general populations. METHODS: The cancer registry of North Rhine-Westphalia identified incident cases of stomach, colorectal, lung, breast and prostate cancer in resettlers and the general population of the administrative district of Münster (Germany) between 2004 and 2013. The Tomsk cancer registry collected the same data in ethnic Germans and the general population of the Tomsk region (Russia). We used standardised incidence rate ratios (SIRs) to compare rates of resettlers and ethnic Germans with the respective general populations. RESULTS: The total number of person-years under risk was 83,289 for ethnic Germans, 8,006,775 for the population of Tomsk, 219,604 for resettlers, and 20,516,782 for the population of Münster. Incidence of the five investigated cancer types among ethnic Germans did not differ from incidence of the general population of Tomsk. Compared to the general population of Tomsk, incidence among resettlers was higher for colorectal cancer in both sexes (females: SIR 1.45 [95% CI 1.14-1.83], males: SIR 1.56 [95% CI 1.23-1.97]), breast cancer in females (SIR 1.65 [95% CI 1.40-1.95]), and prostate cancer (SIR 1.64 [95% CI 1.34-2.01]). Incidence rates of these cancer types among resettlers were more similar to rates of the general population of Münster. Incidence of stomach and lung cancer did not differ between resettlers and the general population of Tomsk. CONCLUSIONS: After an average stay of 15 years, we observed that incidence of colorectal, breast and prostate cancer among resettlers converged to levels of the general population of Münster. Resettler's incidence of stomach and lung cancer, however, was comparable to incidence in their population of origin. Causes must be investigated in subsequent analytical studies.

BACKGROUND: Triggered by the successive implementation of organized mammography screening programs (MSPs) throughout western European countries over the last decades, there is an ongoing debate questioning their effectiveness. Since it is difficult to assess the effect of MSPs on a population level, we rather aim to assess the impact of the implementation itself on breast cancer mortality rates utilizing an ecological study design. METHODS: We analyzed age group-specific (50-59, 60-69 and 70-79 years) female breast cancer mortality rates in 14 western European countries between 1980 and 2017 using Joinpoint regression, interrupted time series (ITS) regression and multivariable Poisson regression. RESULTS: The Joinpoint analysis demonstrated decreasing trends resulting in annual percentage changes ranging from - 1.5% to - 5.4% (50-59), - 0.2% to - 8.1% (60-69) and 0% to - 7.1% (70-79) depending on the country within 3 years after MSP implementation. The ITS analysis results in highly significant interaction terms (calendar year * binary MSP indicator) for all age groups. The multivariable regression using "calendar year", "year of MSP implementation" and "years with MSP" as independent variables yielded a significant yearly decrease for "years with MSP" ranging from 0.9 to 1.2%. CONCLUSIONS: The results of this study suggest a positive association between the implementation of MSPs and the (accelerated) reduction of breast cancer mortality rates. Measuring and quantifying the isolated effect of MSPs on a population level will require additional studies using individual data.

BACKGROUND: In this study, we compared stage at diagnosis, standardized incidence ratio (SIR) and standardized mortality ratio (SMR) of most frequent cancer diagnoses between re-settlers (Aussiedler) from the former Soviet Union and the general population in the Saarland in Germany to assess possible delays in diagnosis of cancer among this migrant group. METHODS: Lung cancer, colorectal cancer, breast cancer, prostate cancer, malignant melanoma of the skin and stomach cancer diagnoses among a cohort of 18,619 re-settlers living in the Saarland between 1990 and 2009 were identified by the federal state's cancer registry. Vital status was available for the respective time-period and used to calculate SIR and SMR in comparison to the autochthonous population. Tumor stages were condensed into local and advanced stages. Odds ratios (OR) for an advanced tumor stage were modeled in dependence of re-settler-status and relevant covariates by logistic regression. Missing values were addressed in a sensitivity analysis. The influence of duration of stay in Germany on advanced stage diagnosis was analyzed among re-settlers. RESULTS: SIR and SMR of lung and breast cancer were lower among female re-settlers, while SIR and SMR of colorectal and prostate cancer were lower among male re-settlers. SIR and SMR of stomach cancer were elevated among both sexes. Female re-settlers showed an elevated OR for being diagnosed with advanced stage breast cancer. Both male and female re-settlers showed an elevated OR when observing all six sites combined (OR among males 1.47, p = 0.04; OR among females 1.37, p = 0.05). The result of elevated ORs was supported in the sensitivity analysis. Finally, male re-settlers showed a weak association between duration of stay in Germany and reduced risk for advanced stage diagnosis. CONCLUSION: Re-settlers were more likely to be diagnosed at an advanced tumor stage. These findings are in line with previous research having shown unfavorable health care utilization of re-settlers. Overall, low mortality rates despite an increased risk of advanced stage at diagnosis argue for a sufficient follow-up care, comparable to the autochthonous population.

BACKGROUND: A standard parameter to compare the disease incidence of a cohort relative to the population is the standardized incidence ratio (SIR). For statistical inference is commonly assumed that the denominator, the expected number of cases, is fixed. If a disease registry is available, incident cases can sometimes be identified by linkage with the registry, however, registries may not contain information on migration or death from other causes. A complete follow-up with a population registry may not be possible. In that case, end-of-follow-up date and therefore, exact person-years of observation are unknown. METHODS: We have developed a method to estimate the observation times and to derive the expected number of cases using population data on mortality and migration rates. We investigate the impact of the underlying assumptions with a sensitivity analysis. RESULTS: The method provides a useful estimate of the SIR. We illustrate the method with a numerical example, a simulation study and with a study on standardized cancer incidence ratios in a cohort of migrants relative to the German population. We show that the additional variance induced by the estimation method is small, so that standard methods for inference can be applied. CONCLUSIONS: Estimation of the observation time is possible for cohort studies with incomplete follow-up.

Resettlers (in German: (Spät-)Aussiedler) form one of the biggest migrant groups in Germany. It is known that migrants have different mortality patterns compared to the autochthon population. In this paper, we combined data from three resettler cohorts and examined differences in mortality from non-communicable diseases among resettlers in Germany and the German population. Furthermore, we investigated time trends of cause-specific mortality for 20 years of follow-up and compared it with the German mortality rates. To assess differences in cause-specific mortality between resettlers and the general German population, we calculated standardized mortality ratios (SMRs). To ascertain mortality trends, cause-specific age-standardized mortality rates were calculated and modeled with Poisson regression and fractional polynomials. During the observation period, the study population accumulated almost 800,000 person-years and 5572 deaths were observed. All-cause mortality among resettlers was lower (SMR = 0.91, 95% CI = 0.89-0.94) compared to the general German population, as well as cardiovascular diseases (CVD) mortality (SMR = 0.82, 95% CI = 0.79-0.86). Results for cancer mortality varied considerably by cancer site. Analyses of time trends showed that all-cause and CVD mortality were decreasing over time in resettlers, as well as in the general German population. Lower all-cause mortality among resettlers is mainly explained by lower CVD mortality. Cancer-site specific mortality showed different results. Converging mortality rates may indicate an adaption of lifestyle behavior. However, there are no data on individual risk factors in this study.

BACKGROUND: The WHO Framework Convention on Tobacco Control was shown to effectively lower smoking prevalence in in high income countries, however knowledge for low and middle income settings is sparse. The objective of this study was to describe WHO MPOWER policy measures in thirteen West-African countries and to investigate their correlation with smoking prevalence. METHODS: Age-standardized smoking prevalence data and policy measures were collected from various WHO reports. For analysis MPOWER measures from 2008 and 2010, were combined with prevalence data from 2009 and 2011. Multiple linear regression models were set up. RESULTS: In West-Africa mean smoking prevalence was approximately 20% among males and approximately 3% among females. Policy measures were mostly at a middle or low level. Regression analysis showed that tobacco cessation programs, health warnings on cigarettes, and higher price of cigarettes were negatively correlated with smoking prevalence. Significant effects were observed for only one policy measure (tobacco cessation programs) and only within the male population where smoking prevalence is generally higher. CONCLUSIONS: Tobacco control policies are enforced at relatively low levels in West-African countries. However, improving tobacco control policy implementation according to the WHO Framework Convention on Tobacco Control should assist in the reduction of smoking prevalence in African countries, thereby counteracting pro-smoking initiatives set forth by the tobacco industry.

BACKGROUND: The burden of cardiovascular diseases (CVDs) is much more pronounced in Eastern Europe, a spatial gradient within Europe still exists. However, former studies showed a significantly lower CVD mortality of German repatriates from the Former Soviet Union compared with the German population. METHODS: All-cause, CVD and ischemic heart disease (IHD) standardized mortality ratio (SMR), IHD standardized incidence ratio and annual age-standardized mortality and acute myocardial infarction (AMI) incidence rates were calculated in a retrospective cohort. Time trends were investigated by loess regression. RESULTS: A total of 6378 German repatriates were observed from 1990 to 2010, accumulating 92 149 person-years. We observed a lower all-cause mortality [SMR = 0.86 (0.75, 0.98)] in females and CVD mortality [International Statistical Classification of Diseases and Related Health Problems, version 10 (ICD) 10: I00-I99; SMR = 0.82 (0.65, 1.03)] and IHD mortality (I20-I25) [SMR = 0.84 (0.60, 1.15)] in males. In contrast, AMI incidence was significantly higher in male repatriates [standardized incidence ratio = 1.30 (1.02, 1.65)]. Whereas in the general population, mortality rates of CVD, IHD and AMI incidence have continuously decreased over time, the pattern in the repatriates was not as clear. In male repatriates, mortality rates seemed to be lower after immigration and remained rather constant. Incidence rates possibly exceed Germans rates by now. CONCLUSIONS: A possible historical repatriates' IHD advantage shown in former studies has disappeared. The increasing AMI incidence in (male) repatriates might demonstrate the delaying onset of the impact of changes in the CVD risk profile due to migration. Health politics and the health system should be sensitized and take care of the development of IHD mortality and AMI incidence among the repatriates.

Background: Even though Thailand has launched multiple migrant health policies, migrants still face various barriers in accessing health care. To some extent, these barriers may be reduced by health microinsurance. The M-FUND is a low-cost, not-for-profit health protection scheme for migrant workers in Thailand, created by Dreamlopments Social Enterprise and Foundation to support sustainable access to quality healthcare services for migrants. We aimed to investigate the impact of the M-FUND on utilization of health services. Methods: Over a period of three months, we conducted quantitative face-to-face interviews with 408 M-FUND members, and 452 age, sex and location matched non-member controls in Tak Province, Thailand. We compared utilization of health services between members and non-members using logistic regression controlling for a number of socio-demographic variables and variables related to migration such as years in Thailand, legal status, etc. Findings: M-FUND members were more likely to have utilized outpatient services (adjusted odds ratio: 1·74, 95 % confidence interval: 1·24-2·44), inpatient services (2·96, 1.11-7·92), and emergency care (1·89, 0·78-4·56), although the latter was not statistically significant. Members were more likely not to have purchased medicines over-the-counter (1·67, 1·22-2·27) than non-members. Members were also more likely to have utilized any additional specific service during a consultation (2·31, 1·49-3·58) including any type of imaging method (2·62, 1·29-5·29) and blood tests (1·64, 0·99-2·71). There were some differences between men and women, but most were not statistically significant. Interpretation: The M-FUND health microinsurance was positively associated with the utilization of all major types of health services among migrant workers and their dependents in Thailand. For migrants, particularly vulnerable migrant workers and their dependents, the M-FUND appears to be a good approach to reducing barriers to health care. This study of the impact of health microinsurance for migrants provides important information for policy and program planners in the field of migrant health. However, more research is needed on health microinsurance schemes for migrants in different settings and for other underserved communities as well as the sex-specific impact on health service utilization.
