Functional and Postural Lateral Preferences in Humans: Interrelations and Life-Span Age Differences
2002
This study aimed to provide data on lateral preferences among older subjects, to analyze age differences, and to determine interrelations between lateral preferences. Four functional preferences (handedness, footedness, eyedness, earedness) and three postural lateral preferences (hand-clasping, arm-folding, leg-crossing) were assessed in 628 Germans (252 men, 376 women) aged between 19 and 90 years. Sex differences, age differences, and associations between lateralities were analyzed applying chi-square tests. Logistic regression analyses considering age, sex, and interactions between variables were applied to analyze combined effects on laterality measures. Right-sided preference for hande…
The benefits of sustained leisure-time physical activity on job strain
2010
Background The long-term effects of leisure-time physical activity (LTPA) on job strain have not been assessed in a large prospective population-based cohort study. Aims To examine the relationship between the LTPA and the prevalence of job strain. Methods The participants were 861 full-time employees (406 men and 455 women), aged 24―39 years in 2001, from the ongoing Cardiovascular Risk in Young Finns Study. LTPA was assessed using a self-report questionnaire in 1992 and in 2001. The participants were grouped into four categories according to tertiles of LTPA index at two time points: persistently active, increasingly active, decreasingly active and persistently inactive. Job strain was me…
Death certificate only proportions should be age adjusted in studies comparing cancer survival across populations and over time
2015
Abstract Background The proportion of cases notified by death certificate only (DCO) is a commonly used data quality indicator in studies comparing cancer survival across regions and over time. We aimed to assess dependence of DCO proportions on the age structure of cancer patients. Methods Using data from a national cancer survival study in Germany, we determined age specific and overall (crude) DCO proportions for 24 common forms of cancer. We then derived overall (crude) DCO proportions expected in case of shifts of the age distribution of the cancer populations by 5 and 10 years, respectively, assuming age specific DCO proportions to remain constant. Results Median DCO proportions acros…
The association between night eating and body mass depends on age
2014
Night eating syndrome (NES) is marked by substantial evening or nocturnal food intake, insomnia, morning anorexia, and depressed mood. Originally, NES was described as an eating pattern among obese individuals.However, subsequent studies showed that NES also occurs among non-obese individuals, who appear to be younger than obese individuals with NES. Thus, it has been proposed that NES may lead to future weight gain,which may explain inconsistent findings about associations between NES and body mass. The current study investigated the relationships between age, body mass index (BMI), and night eating severity in a representative sample of German adults (n = 2317). It was found that age mode…
Testing a model of physical activity and obesity tracking from youth to adulthood: the cardiovascular risk in young Finns study
2006
To test a potential model of the relationship between physical activity and obesity from youth to adulthood.Longitudinal study data from the cardiovascular risk in young Finns study.A total of 1319 boys (n=626) and girls (n=693) aged 9, 12, 15 and 18 years were randomly selected from five university towns and their rural surroundings in 1980. They were followed up for 21 years. In 2001 they were 30, 33, 36 and 39 years old.Physical activity was assessed by a short questionnaire at two measurement points. Obesity was measured by body mass index (BMI) and sum of skinfolds in 1980 and BMI and waist circumference in 2001.Structural equation analysis (LISREL) indicated that the prevalence of abd…
Trends in survival of multiple myeloma patients in Germany and the United States in the first decade of the 21st century
2015
Multiple myeloma is a chronic, incurable but highly treatable neoplasm. Recent population-based studies have shown improvements in survival for patients diagnosed in the early 21st century. Here, we examine trends in survival for patients diagnosed with multiple myeloma in Germany and the United States (US) between 2002 and 2010. Data were extracted from 11 population-based cancer registries in Germany and from the Surveillance, Epidemiology and End Results database in the US. Myeloma patients aged 15-74 years with diagnosis and follow-up between 1997 and 2010 from Germany and the US were included. Period analysis was employed to assess trends in 5-year relative survival in Germany and the …
Incidence of amyotrophic lateral sclerosis in Sicily: A population based study
2012
Our objective was to investigate incidence of amyotrophic lateral sclerosis (ALS) in Sicily, southern Italy, by means of a population based study. We included people with ALS resident in fi ve Sicilian provinces, whose onset occurred in the two-year period 2005 2006 (population at 31 December 2006: 3,481,096 inhabitants). A multisource case-fi nding procedure was adopted and patients were classifi ed as affected by ALS according to revised El Escorial criteria. During the two-year surveillance period, 97 patients meeting eligibility criteria included 57 males (58.8%) and 40 females (41.2%). Crude annual incidence rate was 1.4/100,000 person years (95% CI 1.33 1.47). The incidence rate was h…
Impaired Health-Related Quality of Life in Inflammatory Bowel Diseases Psychosocial Impact and Coping Styles in a National German Sample
2001
The purpose of this study is to give a detailed survey of the disease-specific and generic quality of life (HRQOL) of adult patients suffering from inflammatory bowel disease (IBD) in Germany.1322 patients suffering from IBD were examined in a cross-sectional study. A questionnaire assessing disease-specific and generic quality of life, coping, and hopelessness was sent to members of the German Crohn/Colitis association.Compared to the general population, the generic HRQOL in IBD patients is significantly reduced. Active coping has a negative influence on patients' generic physical HRQOL during an active phase (beta = -0.31), while this association is not present in the case of patients in …
Psychosocial and occupational risk perception among health care workers: a Moroccan multicenter study.
2015
Background International studies on occupational risks in public hospitals are infrequent and only few researchers have focused on psychosocial stress in Moroccan Health Care Workers (HCWs). The aim of this study was to present and analyze Moroccan HCWs occupational risk perception. Across nine public hospitals from three Moroccan regions (northern, central and southern), a 49 item French questionnaire with 4 occupational risks subscales, was distributed to 4746 HCWs. This questionnaire was based on the Job Content Questionnaire. Psychosocial job demand, job decision latitude and social support scores analysis were used to isolate high strain jobs. Occupational risks and high strain percept…
Dietary polyunsaturated fatty acids may increase plasma LDL-cholesterol and plasma cholesterol concentrations in carriers of an ABCG1 gene single nuc…
2011
Abstract Background ABCG1 mediates cellular cholesterol transport, but there is very little known about the influence of ABCG1 polymorphisms on human plasma lipoprotein cholesterol concentrations or on the interactions of these polymorphisms with diet. Objective Our objective was to investigate whether interactions between PUFA intake and ABCG1 polymorphisms modulate associations with plasma total cholesterol (TC), LDL- and HDL-cholesterol in two Spanish populations. Methods We grounded our investigation on two general population-based studies: the Hortega study (population A) and the Pizarra study (population B). Participants included 1178 individuals (50.0% women, age range 21–85 years) a…
