Heterogeneous contributions of change in population distribution of body mass index to change in obesity and underweight

From 1985 to 2016, the prevalence of underweight decreased, and that of obesity and severe obesity increased, in most regions, with significant variation in the magnitude of these changes across regions. We investigated how much change in mean body mass index (BMI) explains changes in the prevalence of underweight, obesity, and severe obesity in different regions using data from 2896 population-based studies with 187 million participants. Changes in the prevalence of underweight and total obesity, and to a lesser extent severe obesity, are largely driven by shifts in the distribution of BMI, with smaller contributions from changes in the shape of the distribution. In East and Southeast Asia…

Le réseau REDSIAM (Réseau données Sniiram) – Spécial REDSIAM

The French national health database (SNIIRAM) proved to be very useful for epidemiology, health economics, evaluation, surveillance or public health. However, it is a complex database requiring important resources and expertise for being used. The REDSIAM network has been set up for promoting the collaboration of teams working on the Sniiram. The main aim of REDSIAM is to develop and validate methods for analyzing the Sniiram database for research, surveillance, evaluation and public health purposes by sharing the knowledge and experience of specialized teams in the fields of diseases identification from the Sniiram data. The work conducted within the network is devoted to the development a…

Impact of recommendations on the initial therapy of Parkinson’s disease: A population-based study in France

International audience; Levodopa induces long-term motor complications in Parkinson's disease (PD). Therapeutic strategies that prevent motor complications are needed. Our aim was to evaluate the impact of recommendations of a French consensus conference published in 2000 on initial PD therapy. We identified 308 PD patients as part of a population-based study performed within the Mutualité Sociale Agricole in five French districts (2007). Neurologists confirmed PD diagnosis. We compared initial therapy in 102 patients treated before 12/31/2000 to that of 206 patients treated afterwards. Initial treatment was in agreement with the recommendations if dopamine agonists were used in patients <6…
