Definitions of healthy ageing include survival to a specific age, being free of chronic diseases, autonomy in activities of daily living, wellbeing, good quality of life, high social participation, only mild cognitive or functional impairment, and little or no disability. The working group Epidemiology of Ageing of the German Association of Epidemiology organized a workshop in 2012 with the aim to present different indicators used in German studies and to discuss their impact on health for an ageing middle-European population. Workshop presentations focused on prevalence of chronic diseases and multimorbidity, development of healthy life expectancy at the transition to oldest-age, physical activity, assessment of cognitive capability, and functioning and disability in old age. The communication describes the results regarding specific indicators for Germany, and hereby contributes to the further development of a set of indicators for the assessment of healthy ageing.
We report on a nested case-control study with 328 cases with second malignant neoplasm (SMN) following childhood cancer and 639 matched controls based on the German Childhood Cancer Registry. In the adjusted overall analysis, the odds ratio (OR) for SMN following any radiotherapy or chemotherapy is 2.1 [95% confidence interval (CI): 1.8-3.3] and 1.8 (95% CI: 0.98-3.1), respectively. The strongest effect is seen for alkylating agents (OR=2.0, 95% CI: 1.2-3.3). The risk of SMN after leukemia is pronounced for antimetabolites (OR=17.2, 95% CI: 1.7-177) and asparaginase (OR=4.3, 95% CI: 1.7-11.0). Following solid tumors, the greatest effect is seen for platinum derivatives (OR=4.1, 95% CI: 1.7-10.1). For anthracyclines, a decreased risk is observed (OR=0.3, 95% CI: 0.1-0.6). Secondary solid tumors are mainly associated with radiotherapy (OR=4.5, 95% CI: 2.5-8.0), especially secondary carcinomas. Secondary acute myeloid leukemia and myelodysplastic syndrome are mainly associated with alkylating agents (OR=8.5, 95% CI: 0.97-74.8), asparaginase (OR=6.8, 95% CI: 2.3-20.6), and platinum derivatives (OR=4.5, 95% CI: 1.5-13.6). The observed risks are in many instances lower than the ones published in previous studies relating to earlier treatment eras of the primary diseases. These differences may be attributed to less toxic but still effective treatment regimes but also to differences in the length of follow-up.
The phase of retirement has been steadily growing since the 1950s. Rules and regulations related to retirement have been changing. Recent cohorts have reached this phase in better health than previous ones. Until recently, retirement has been rather void of societal expectations, leaving room for individual decisions regarding amount and type of activity. Thus, investigating activity patterns displayed during this life phase, their predictors and outcomes seems overdue. The study addresses three questions: (a) Which distinct clusters of productive activities among retirees can be identified in Germany? (b) Do activity patterns of clusters follow complementary or substitutive composition rules? (c) Which are the most important predictors of cluster membership? Using probability-based sample data (N = 2,141) from the survey ‘Transitions and Old Age Potential’ (TOP), this study investigated clusters of productive activities among retirees aged 60–70 years in Germany. The activities examined included paid work after retirement, formal and informal volunteering, child care and care-giving. Results showed a four-cluster structure. The clusters (Multiple Engagers, Volunteers, Family Helpers and Family Disengagers) differed with regard to the composition and the intensity of productive activities. Both complementary and substitutive relations were identified within clusters. Individual, familial and economic resources were predictors of cluster membership. Results are discussed with regard to role theory, cumulative inequality theory and the ongoing debate about old-age potential.
This paper presents data on the German and Europe-wide incidence, time trends and regional variations of childhood leukaemia. Data were provided by the German Childhood Cancer Registry (GCCR), a population-based cancer registry recording all cases of malignant diseases in children under 15 y of age residing in Germany and by the Automated Childhood Cancer Information System (ACCIS) co-ordinated at International Agency for Research on Cancer, Lyon, that combines and evaluates data from several European population-based cancer registries. The incidence of leukaemia (44.0 per million) has increased in Europe as well as in Germany in the last decades (0.6% annually on average). Germany shows no systematic aggregation of regions with low or high cancer incidence in terms of regional clustering. Incidence rates differ between European regions with the highest rates in Northern Europe (48.0 per million) and the lowest rates in Eastern Europe (39.1). Altogether, the results from ACCIS and the GCCR show good agreement.
So far, only a few studies investigated occupational exposure to ionizing radiation in pregnancy to cause birth defects (BDs). No association between BDs and ionizing radiation, although described for high-dose exposure, could ever be confirmed for employees, or specific job titles. Here, an explorative analysis of a prospective population-based birth cohort used to quantify the prevalence of BDs in infants between 1/2007 and 2/2008 is presented. An active examination of all livebirths by specially trained paediatricians in two defined areas was performed. Additionally, a study-specific questionnaire distributed among all becoming mothers in the surveyed regions included questions on maternal occupational exposure to ionizing radiation within the first trimester of pregnancy. In 3,816 births (including 165 infants with BDs; 4.3%), maternal answers concerning possible exposures to medical and occupational ionizing radiation were available. Relative risk (RR) estimates in mothers surveyed for occupational exposure to ionizing radiation (wearing a radiation dosimeter) and BDs in the offspring were calculated exploratively. A higher prevalence of infants with BDs (n = 4; 13.8%) was documented in newborns of the 29 surveyed mothers compared to that in 3,787 births from unexposed mothers (n = 161; 4.3%), corresponding to a RR of 3.2 (1.2-8.7). Excluding deformations, the RR increased to 4.0 (1.5-10.7). Adjustment for possible confounders did not change the results substantially.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
