Cross-country comparisons of trends in adolescent psychosomatic symptoms : a Rasch analysis of HBSC data from four Nordic countries
2018
BACKGROUND: To analyse the psychometric properties of the HBSC Symptom Checklist (HBSC-SCL) on psychosomatic symptoms with a focus on the operating characteristics of the items, and on the impacts of measurement distortions on the comparisons of person measures across time and between countries.METHODS: Data were collected in 1993/94, 1997/98, 2001/02, 2005/06, 2008/09, 2013/14 in Denmark, Finland, Norway and Sweden as part of the Health Behaviour in School-aged Children (HBSC) study. Data comprised 116,531 students 11, 13 and 15 years old. Rasch analysis was conducted of the HBSC-SCL consisting of eight items with a focus on Differential Item Functioning (DIF) and item threshold ordering. …
Trends in life satisfaction in European and North-American adolescents from 2002 to 2010 in over 30 countries
2015
Background: Life satisfaction (LS) is an indicator which is widely used for assessing the perception of a child's feeling about his life. Methods: LS is assessed in Health Behaviour in School-aged Children via the Cantril ladder with 10 steps indicating the worst and best possible life. This range of values (0-10) was dichotomized into 'low' (0-5) vs. 'high' (6-10). Countries, age groups and genders were compared based on the odds ratio (OR) of declaring a higher LS in 2010 with respect to 2002. Results: Analyzing the difference between 2002 and 2010, six countries from Western Europe show decreasing LS: Austria, Canada, Switzerland, Denmark, Finland and Greenland. In contrast, a group of E…
Worldwide trends in diabetes since 1980: a pooled analysis of 751 population-based studies with 4.4 million participants
2016
Background One of the global targets for non-communicable diseases is to halt, by 2025, the rise in the age-standardised adult prevalence of diabetes at its 2010 levels. We aimed to estimate worldwide trends in diabetes, how likely it is for countries to achieve the global target, and how changes in prevalence, together with population growth and ageing, are affecting the number of adults with diabetes. Methods We pooled data from population-based studies that had collected data on diabetes through measurement of its biomarkers. We used a Bayesian hierarchical model to estimate trends in diabetes prevalence-defined as fasting plasma glucose of 7.0 mmol/L or higher, or history of diagnosis w…
Trends in net survival from stomach cancer in six European Latin countries: results from the SUDCAN population-based study
2016
IF 2.415; International audience; Gastric cancers are a clinical challenge. The aim of the SUDCAN collaborative study was to compare the net survival from gastric cancer between six European Latin countries (Belgium, France, Italy, Portugal, Spain and Switzerland) and explore the trends in net survival and in the dynamics of the excess mortality rates (EMRs) up to 5 years after diagnosis. The data were extracted from the EUROCARE-5 database. First, net survival was studied over the period 2000-2004 using the Pohar-Perme estimator. For trend analyses, the study period was specific to each country. The results are reported from 1992 to 2004 in France, Italy, Spain and Switzerland and from 200…
Trends in net survival from colon cancer in six European Latin countries: results from the SUDCAN population-based study.
2016
IF 2.415; International audience; Colon cancer represents a major public health issue. The aim of the SUDCAN collaborative study was to compare the net survival from colon cancer between six European Latin countries (Belgium, France, Italy, Portugal, Spain, and Switzerland) and provide trends in net survival and dynamics of the excess mortality rates up to 5 years after diagnosis. The data were extracted from the EUROCARE-5 database. First, net survival was studied over the 2000-2004 period using the Pohar-Perme estimator. For trend analyses, the study period was specific to each country. Results were reported from 1992 to 2004 in France, Italy, Spain, and Switzerland and from 2000 to 2004 …
Trends in net survival from liver cancer in six European Latin countries: results from the SUDCAN population-based study
2016
Liver cancer represents a major clinical challenge. The aim of the SUDCAN collaborative study was to compare the net survival from liver cancer between six European Latin countries (Belgium, France, Italy, Portugal, Spain and Switzerland) and provide trends in net survival and dynamics of excess mortality rates (EMRs) up to 5 years after diagnosis. The data were extracted from the EUROCARE-5 database. First, net survival was studied over the period 2000-2004 using the Pohar-Perme estimator. For trend analyses, the study period was specific to each country. Results are reported from 1992 to 2004 in France, Italy, Spain and Switzerland and from 2000 to 2004 in Belgium and Portugal. These tren…
The impact of overdiagnosis on thyroid cancer epidemic in Italy,1998-2012
2018
Aims: In Italy, incidence rates of thyroid cancer (TC) are among the highest world- wide with substantial intracountry heterogeneity. The aim of the study was to examine time trends of TC incidence in Italy and to estimate the proportion of TC cases potentially attribut- able to overdiagnosis. Methods: Data on TC cases reported to Italian cancer registries during 1998e2012 aged <85 years were included. Age-standardised incidence rates (ASR) were computed by sex, period, and histology. TC overdiagnosis was estimated by sex, period, age, and Italian region. Results: In Italy between 1998e2002 and 2008e2012, TC ASR increased of 74% in women (from 16.2 to 28.2/100,000) and of 90% in men (fro…
Changes in hepatocellular carcinoma aggressiveness characteristics with an increase in tumor diameter
2021
Background: Hepatocellular carcinoma prognosis depends on both liver and tumor determinants, especially on maximum tumor diameter, multifocality, and presence of portal vein thrombosis, despite apparently complete tumor removal by resection or liver transplantation. Aims: To examine parameters of hepatocellular carcinoma aggressiveness as tumor size increases. Methods: A large hepatocellular carcinoma database was examined for trends in serum alpha-fetoprotein and the percentage of patients with macroscopic portal vein thrombosis or tumor multifocality. Results: A total of 13,016 hepatocellular carcinoma patients were identified having full tumor and survival data. Of these, 76.56% were mal…
Temporal trends in the incidence rate of childhood cancer in Germany 1987-2004.
2007
The German Childhood Cancer Registry regularly presents graphs of childhood cancer incidence rates by period, but no systematic analysis. The Automated Childhood Cancer Information System-project found an increasing trend in Europe. Against this background we present the first detailed trend analysis of childhood (aged under 15) malignancies in Germany. We examined incidence rates separately in western Germany 1987-2004 and eastern Germany 1991-2004. We analyzed all malignancies, all main diagnostic groups and relevant subsets using an age-period-cohort model. Additionally we fitted fractional polynomials to assess the linearity of the drift. All malignancies combined (excluding Central Ner…
The use of national administrative data to describe the spatial distribution of in-hospital mortality following stroke in France, 2008-2011.
2016
International audience; Background: In the context of implementing the National Stroke Plan in France, a spatial approach was used to measure inequalities in this disease. Using the national PMSI-MCO databases, we analyzed the in-hospital prevalence of stroke and established a map of in-hospital mortality rates with regard to the socio-demographic structure of the country.Methods: The principal characteristics of patients identified according to ICD10 codes relative to stroke (in accordance with earlier validation work) were studied. A map of standardized mortality rates at the level of PMSI geographic codes was established. An exploratory analysis (principal component analysis followed by …
