Implementation and evaluation of the population-based programme "health literacy in school-aged children" (GeKoKidS)

Aim: Health literacy (HL) is a key outcome of health education. Low HL is associated with a higher risk of health-related impairments and high health-related costs. This article therefore describes the contents and evaluation of the school-based programme “Health literacy in school-aged children” (GeKoKidS) and its acceptance by teachers. A second focus of the study is the description of methods to increase the response of schools, students and parents as a crucial condition for the validity and generalizability of results from epidemiologic prevention studies. Subjects and methods: The evaluation of the prevention program GeKoKidS included 5th grade students aged 9–13 years in schools in the region of Greifswald and East Pomerania [longitudinal randomised control group pre-post design (RCT)]. Data collections took place within the extended school dentist examination visits at the beginning of the 2007/2008 school year and at the beginning of the second half term of the 2008/2009 school year. This included medical examinations and self-completion questionnaires of students, parents and teachers. The study was authorised by the data protection commissioner of Mecklenburg-West Pomerania, the Ministry of Education, Science and Culture of Mecklenburg-West Pomerania and the Ethics Commitee of the Ernst Moritz Arndt University Greifswald. Based on the authorisation of the data protection concept and concerns about selective response, parents were not granted a consent but rather a right to refuse participation. Results: In Greifswald/East Pomerania, 19 of 22 schools with 5th year classes participated in GeKoKidS (response rate: 86.3%). Out of 914 eligible students in the participating schools, 882 children (96.4%) took part in the school dentist examinations. A total of 863 children (94.4%) participated in the extended school dentist examination; 852 children (93.2%) took part in the student survey. In the parental survey 721 parents participated (response rate: 78.8%). A high level of acceptance referring to teacher training and the appropriateness of the GeKoKidS programme was achieved. Conclusion: As shown by the low rate of refusal, the programme and the evaluation study were well accepted. Possible reasons for these results could be the chosen procedure of establishing contact with schools before sending the questionnaires and the parent’s right to refuse their child's participation instead of giving an active confirmation. Because of this high response rate, the database enables comprehensive conclusions to be reached on the health-related state of students in Greifswald/East Pomerania

Association between lifestyle factors and headache

Modification of lifestyle habits is a key preventive strategy for many diseases. The role of lifestyle for the onset of headache in general and for specific headache types, such as migraine and tension-type headache (TTH), has been discussed for many years. Most results, however, were inconsistent and data on the association between lifestyle factors and probable headache forms are completely lacking. We evaluated the cross-sectional association between different lifestyle factors and headache subtypes using data from three different German cohorts. Information was assessed by standardized face-to-face interviews. Lifestyle factors included alcohol consumption, smoking status, physical activity and body mass index. According to the 2004 diagnostic criteria, we distinguished the following headache types: migraine, TTH and their probable forms. Regional variations of lifestyle factors were observed. In the age- and gender-adjusted logistic regression models, none of the lifestyle factors was statistically significant associated with migraine, TTH, and their probable headache forms. In addition, we found no association between headache subtypes and the health index representing the sum of individual lifestyle factors. The lifestyle factors such as alcohol consumption, smoking, physical activity and overweight seem to be unrelated to migraine and TTH prevalence. For a judgement on their role in the onset of new or first attacks of migraine or TTH (incident cases), prospective cohort studies are required

Demographic Changes: The Impact for Safe Blood Supply

The population structure in most European countries is currently changing, with a shift from younger to older age groups. Only sparse data exist on the impact of these demographic changes on future blood demand and supply. Data on blood recipients are sparse and unconnected to data on blood donors. The first part of this review summarizes studies on the effect of the demographic change on blood supply and demand. With respect to studies in North America and Europe on the impact of demographic changes on future blood supply, the demographic trends will affect many regions in the Western world similarly. These effects are most pronounced in the new member states of the European Union where birth rates declined abruptly after 1989. Coordinated efforts will be required to prevent blood shortages based upon these demographic trends in Western societies. The second part of this review is an overview of methodological approaches to obtain data on the sociodemographic background of the blood donor population

Changing maternity leave policy: Short-term effects on fertility rates and demographic variables in Germany

Changes in reproductive behaviour and decreasing fertility rates have recently led to policy actions that attempt to counteract these developments. Evidence on the efficacy of such policy interventions, however, is limited. The present analysis examines fertility rates and demographic variables of a population in Germany in response to new maternity leave regulations, which were introduced in January 2007. As part of a population-based survey of neonates in Pomerania (SNiP), all births in the study region from the period 23 months prior to January 1st, 2007 until 23 months afterwards were examined. Crude Birth Rates (CBR) per month, General Fertility Rates (GFR) per month, parity and sociodemographic variables were compared using bivariate techniques. Logistic regression analysis was performed. No statistically significant difference in the CBR or GFR after Jan. 1st, 2007 was found. There were statistically significant differences in other demographic variables, however. The proportion of mothers who (a) were employed full-time before pregnancy; (b) came from a higher socioeconomic status; and (c) had higher income levels all increased after January 1st, 2007. The magnitude of these effects was higher in multigravid women. Forward stepwise logistic regression found an odds ratio of 1.79 for women with a family income of more than 3000[euro] to give birth after the new law was introduced. This is the first analysis of population-based data that examines fertility rates and sociodemographic variables in response to new legal regulations. No short-term effects on birth rates were detected, but there was a differential effect on the subgroup of multigravidae. The focus of this policy was to provide financial support, which is certainly important, but the complexity of having a child suggests that attitudinal and motivational aspects also need to be taken into account. Furthermore, these analyses were only able to evaluate the short-term consequences of the policy; further studies are needed to assess for different, long-term effects.Fertility rate Sociodemography Maternity leave policy Germany

Discrimination and the Effects of Drug Testing on Black Employment

Nearly half of U.S. employers test job applicants and workers for drugs. I use variation in the timing and nature of drug testing regulation to study discrimination against blacks related to perceived drug use. I find evidence of widespread discrimination against blacks in the absence of drug testing. Adoption of pro-testing legislation increases the share of blacks working in the testing sector by 7 to 30 % and relative wages by 1.4-12.0%, with the largest shifts among low skilled black men. Results suggest that employers substitute white women for blacks in the absence of testing
