[Epidemiologic studies among foreign immigrants in Germany--rational and obstacles].

About 7.2 million foreign nationals are living in Germany. Only few epidemiological studies have assessed their health status, unlike in other countries with large migrant populations. Hence, it is not known whether foreigners in Germany experience special health risks and whether there is a need for specific public health interventions. The size of the group (9% of the total population) and their increasing length of stay further emphasise the need for epidemiological research on migrants. In this article we describe the obstacles for such studies in Germany: difficulties in characterising the group of interest; problems of availability and accessibility of data sources; and aspects of data protection. Minor changes in mortality statistics and improved access to existing data sources within the limits of data protection would improve research opportunities.

Monitoring cardiovascular disease in Zimbabwe: a review of needs and options.

The relative and absolute importance of cardiovascular disease (CVD) in countries of sub-Saharan Africa is assumed to be increasing, but information on morbidity, mortality and prevalence of risk factors is scant. This paper reviews available information on CVD in Zimbabwe; in particular, which type of CVD is important, which segments of the population are affected, which risk factors are relevant and at what levels they are present. Based on the findings, options for monitoring CVD rates and risk factors in Zimbabwe are discussed. For the purpose of identifying risk groups and monitoring secular trends, CVD morbidity data derived from the National Health Information System are insufficient in terms of completeness, accuracy and precision of diagnosis. Useful vital registration data are available for Harare, where persons aged 45 to 64 years experience a relatively high mortality from hypertensive sequelae and a low mortality from ischaemic heart disease. This finding, however, cannot be generalised. Clinical studies confirm a high prevalence of hypertension; it is presently the most important risk factor for CVD. Smoking rates, however, appear to be increasing. Little is known about CVD rates and levels of risk factors in poor and rural population strata and in ethnic minorities. Options to improve monitoring of CVD morbidity and risk factor levels include establishing community registries of stroke and repeatedly examining representative population samples. Nation wide vital registration would be desirable to monitor CVD mortality but appears not to be feasible at present; maintaining a sample registration system would be prohibitively expensive.

Mothers voice their opinion on immunization services.

A survey of the Expanded Programme on Immunization (EPI) in eastern Zimbabwe showed a low valid immunization coverage by one year of age. While health personnel originally thought traditional and religious beliefs were to blame, the survey indicated the problem lay in the poor quality of EPI services. Focus group discussions with mothers confirmed this. Mothers were well informed, highly motivated and had many suggestions on how services could be improved, but were rarely given the opportunity to discuss them with health workers.
