Place of death in France
Overall mortality increased during the first wave of the Covid-19 epidemic. Most Covid-19 deaths took place in public hospitals and nursing homes at old ages. There was a displacement of non-Covid-19 mortality from public hospitals to home and nursing homes, particularly in the most highly exposed area. Among hypotheses to explain such a displacement, population avoidance of hospital care, or redeployment of hospital activity in this emergent con…
Ability of municipality-level deprivation indices to capture social inequalities in perinatal health in France
Some components of FDep and FEDI were less relevant than others for capturing ecological inequalities in PTB and SGA. Results varied for each DI and perinatal outcome studied. These findings highlight the importance of testing DI relevance prior to examining perinatal health inequalities, and suggest the need to develop DIs that are suitable for pregnant women
Expert consultation using the on-line Delphi method for the revision of syndromic groups compiled from emergency data (SOS Médecins and Oscour®) in France
This study involved a panel of national experts with international representation and a good level of involvement throughout the survey. In the absence of a standard definition, the Delphi method has been shown to be useful in defining and validating syndromic surveillance indicators
Self-consciousness impairments in schizophrenia with and without first rank symptoms using the moving rubber hand illusion
Migration experiences, life conditions, and drug use practices of Russian-speaking drug users who live in Paris
BACKGROUND: After the collapse of the Soviet Union at the beginning of the 1990s, people who inject drugs spiked in Eastern Europe. Facing local repression and an array of factors encouraging emigration, some users have migrated to France. This population now make up to a third of the patient list of some harm reduction services in Paris. This article aims to present original data on the sociodemographic profiles of these users, on their migratio…
Diphtheria-Tetanus-Polio, Measles-Mumps-Rubella, and Hepatitis B Vaccination Coverage and Associated Factors among Homeless Children in the Paris Region in 2013
Background : The number of homeless families has increased considerably since the 1990s in France. We aimed to estimate the homeless children vaccination coverage (VC) for diphtheria, tetanus, polio, measles-mumps-rubella and hepatitis B and identify factors associated with insufficient VC according to birthplace. Methods : A cross-sectional survey was conducted among homeless shelter families in the greater Paris area. A nurse conducted face-to-…
A cross sectional survey to estimate prevalence and associated factors of asthma on Reunion Island, Indian Ocean
Preventive actions including asthma diagnosis, promotion of individual measures to reduce risk exposure as well as the development of study to improve knowledge on indoor air allergens are recommended
Waterborne Disease Outbreak Detection
Waterborne disease outbreaks (WBDOs) remain a public health issue in developed countries, but to date the surveillance of WBDOs in France, mainly based on the voluntary reporting of clusters of acute gastrointestinal infections (AGIs) by general practitioners to health authorities, is characterized by low sensitivity. In this context, a detection algorithm using health insurance data and based on a space−time method was developed to improve WBDO …
Prevalence of Mental Disorders and Addictions among Homeless People in the Greater Paris Area, France
The Samenta study was conducted in 2009 in the Greater Paris area to estimate the prevalence of psychiatric disorders in homeless people. A cross-sectional survey was performed with a three-stage random sample of homeless people ( n = 859), including users of day services, emergency shelters, hot meal distribution, long-term rehabilitation centres, and social hotels. Information was collected by a lay interviewer, using the Mini International Neu…
Sexual health in the French military
These results highlight gendered pattern of sexual health in the French military with women suffering greater sexual risks than men. Military health services should include women's health services to address the sexual and reproductive health gender gap
Very low prevalence of iron deficiency among young French children
Although iron deficiency (ID) is considered the most frequent micronutrient deficiency in industrialized countries and is associated with impaired neurodevelopment when occurring in early years, accurate recent estimations of its prevalence are lacking. Our objective was to estimate ID prevalence and associated sociodemographic markers in young children in France. The Saturn-Inf national cross-sectional hospital-based survey recruited 3,831 Frenc…
Update on respondent-driven sampling
In the last 5 years, more than 600 articles using respondent-driven sampling has been published. This article aims to provide an overview of this sampling technique with an update on the key questions that remain when using respondent-driven sampling, with regard to its application and estimators. Respondent-driven sampling was developed by Heckathorn in 1997 and was based on the principle of individuals recruiting other individuals, who themselv…
Screening for Elevated Blood Lead Levels in Children
The decline in children's Blood Lead Levels (BLL) raises questions about the ability of current lead poisoning screening criteria to identify those children most exposed. The objectives of the study were to evaluate the performance of current screening criteria in identifying children with blood lead levels higher than 50 μg/L in France, and to propose new criteria. Data from a national French survey, conducted among 3831 children aged 6 months t…
Burden of influenza, healthcare seeking behaviour and hygiene measures during the A(H1N1)2009 pandemic in France
Self-defined influenza causes a significant burden of illness in the French population and is a frequent cause for consultation. These results allow a more accurate interpretation of influenza surveillance data and an opportunity to adapt future health education messages

Influenza vaccination coverage against seasonal and pandemic influenza and their determinants in France
Overall A(H1N1)2009 influenza vaccine uptake remained low, particularly among individuals with higher risk for influenza and was lower than that observed for seasonal influenza. The reasons behind people's reluctance to be vaccinated need to be investigated further
How generalisable to community samples are clinical trial results for treatment of nicotine dependence
Further studies and interventions should explore the efficacy of tobacco treatment interventions in a larger segment of the population, notably in the subpopulations of people with nicotine dependence who smoke fewer than 10 cigarettes per day or who have comorbid depression
Association Between Peptic Ulcer and Personality Disorders in a Nationally Representative US Sample
Objective: To assess the association between peptic ulcer and a wide range of personality disorders in a large sample representative of the general population in the United States. Methods: Data were drawn from the National Epidemiologic Survey on Alcohol and Related Conditions, on the basis of a face-to-face interview of more than 43,000 adults. Univariate and multivariate logistic regression were used to examine the relationship between self-re…
Conception, échantillonnage, organisation du terrain d'une enquête TLS et nouveaux développements
Afin de suivre la dynamique de l’épidémie d'hépatite C chez les usagers de drogue (UD) en France, l'enquête ANRS-Coquelicot a été réalisée en France entre 2004 et 2007. Cette enquête menée sur 5 villes (Lille, Strasbourg, Paris, Bordeaux, Marseille) est constituée d'un volet épidémiologique et socio-anthropologique. La population cible de cette enquête est à la fois difficile à définir et à atteindre, en raison de profils sociaux et de rapports à…
Design, Sampling, Organising the Field for a TLS Survey and New Developments
The French ANRS-Coquelicot survey was conducted between 2004 and 2007 to follow the dynamics of the epidemic of hepatitis C among drug users (DU) in France. Having taken place in 5 cities (Lille, Strasbourg, Paris, Bordeaux, Marseilles), the survey was constituted of two parts, one epidemiological and the other socio-anthropological. The target population of this survey was both difficult to define and hard to reach, because of diversified social…
Differential improvement in survival among patients with Aids after the introduction of Haart
We explored changes in the survival of patients with AIDS (PWA) according to the availability of antiretroviral drugs (1994-2002). We tested whether changes in the hazard ratio of progression to death (HR) have been homogeneous among various groups of PWA. We included 4158 PWA diagnosed in Paris, notified to the French National Surveillance Institute by 2002. Four calendar periods were defined: monotherapy (1994-95), bitherapy-HAART transition (1…
Influenza pandemic preparedness in France
Background: Influenza pandemics result in excess mortality and social disruption. To assist health authorities update the French pandemic plan, the authors estimated the number of health events (cases, hospitalisations, and deaths) in a pandemic and compared interventions in terms of impact and efficiency. Method: A Monte Carlo simulation model, incorporating probability distributions of key variables, provided estimates of health events (HE) by …
Analysis of Postpartum Lactational Amenorrhoea in Relation to Breast-Feeding
A large multicentre epidemiological study was carried out by WHO between 1991 and 1995 to analyse the duration of lactational amenorrhoea in relation to breast-feeding. The main results of this analysis, which used classical statistical modelling, have been already published. However, some specific aspects of the postpartum fertility amenorrhoea and breast-feeding covariates, and more specifically the observed progressive exhaustion of the breast…
