Background: Despite prevention programs, a rising incidence of sexually transmitted infections is currently reported in France., Aims: Research factors associated with risky sexual behaviors (RSBs) among the French population., Methods: Subjects aged 15-54 years from the French national survey 'Baromètre santé 2010' were included (n = 16 598). RSB was defined as having multiple partners or failure to use condom at first intercourse with a new partner over past 12 months. Factors associated were identified using one logistic regression by gender., Results: The overall RSB prevalence was 9.5%, being higher among men (P < 0.001). Factors associated with RSB for both genders were young age (OR = 1.5), single status (men: OR = 7.1; women: OR = 6.4), homosexual relations (men: OR = 2.0; women: OR = 3.2), low incomes (men: OR = 1.5; women: OR = 1.4), use of cannabis (men: OR = 1.4; women: OR = 3.0). Men-specific factors were history of STI (OR = 2.5) and alcohol drunkenness (OR = 2.2), and women-specific factors history of suicide attempt (OR = 1.6) and history of sexual assault (OR = 1.6)., Conclusions: Confirming most of known determinants of RSB, this study also identified some specific risky patterns for whom preventive actions can be developed: multiusers of psychoactive substances, people living with low incomes, women having sex with women or presenting history of psychological vulnerability (suicide attempts, sexually harassed)., (© The Author 2016.

Objective: The main objective of this study was to evaluate the contribution of a newly implemented daily surveillance system to the management of the 2009 A(H1N1) influenza pandemic by the military decision-makers at different levels in the French Department of Defence., Methods: The study sample included all medical advisors in the Ministry of Defence and the French Armed Forces Staff and also the members of the specific committee dedicated to flu pandemic control. The variables studied were mental representation of epidemiology, relevance, usefulness, and real-time use of surveillance data using quantitative questionnaires and qualitative face-to-face semistructured interviews., Results: Among the risk managers of the flu pandemic in the Armed Forces, 84% responded. The data generated by epidemiological surveillance were considered relevant and useful, and were reported as effectively used. On the basis of the information produced, concrete actions were planned and implemented in the French Armed Forces., Conclusion: In a pandemic situation involving low mortality, the daily monitoring of the disease did not target public health issues, but it was mainly used to assess the availability of the Armed Forces in real time. For the military staff, epidemiological surveillance represents an essential information tool for the conduct of operations., (Reprint & Copyright © 2014 Association of Military Surgeons of the U.S.)

Background: The French military forces had to modify their epidemiological surveillance systems at the time of the 2009 A(H1N1) influenza pandemic. The aim of this article was to present an evaluation of the different systems used., Methods: Two influenza surveillance systems are usually used in the French forces: one permanent (Surveillance épidémiologique des armées or SEA) and one seasonal (Système militaire d'observation de la grippe or SMOG). The pandemic required the implementation of a daily surveillance system (Surveillance quotidienne--SQ), which aimed to monitor disrupted activity owing to 2009 A(H1N1) influenza. The qualitative evaluation of these three systems during the period from September 2009 to February 2010 was performed using 11 criteria based on the list defined by Centers for Disease Control and Prevention of Atlanta., Results: Although it included only 30 sentinel units vs. 320 for the other systems, the SMOG system was the best-performing system in terms of relevance, feasibility, efficacy, quality of data, usefulness, acceptability, efficiency and cost/benefits/costs ratio. The SQ proved very expensive in terms of logistics., Conclusion: The SQ did not bring any significant advantage compared with the weekly surveillance schemes. In the eventuality of another similar episode, influenza surveillance could be significantly improved by using the SMOG system extended to more units for better geographical coverage.

Surveillance of travel-acquired dengue could improve dengue risk estimation in countries without ability. Surveillance in the French army in 2010 to 2011 highlighted 330 dengue cases, mainly in French West Indies and Guiana: DENV-1 circulated in Guadeloupe, Martinique, French Guiana, New Caledonia, Djibouti; DENV-3 in Mayotte and Djibouti; and DENV-4 in French Guiana., (© 2012 International Society of Travel Medicine.)

Background: The aims were to evaluate the accuracy of self-report of past-month cannabis use in a representative sample of French military staff members and to evaluate the scale of the prevarication bias., Method: Data from three cross-sectional surveys conducted between 2005 and 2008 (n = 3493) were used. The characteristics of self-report (sensitivity, specificity, positive predictive value and negative predictive value) were computed using tetrahydrocannabinol detection in urine as the reference., Results: The prevalence for past-month cannabis use was 16.1% and for positive testing was 13.4%. The discriminant power of self-report was good, with an area under the receiver operating characteristics curve 0.90. Specificity (94.5%) and negative predictive values (97.8%) were good, but sensitivity (85.7%) and positive predictive values (70.4%) were lower. The lowest sensitivity values were observed in the higher categories of personnel and in the Navy, which could reflect some prevarication in these sub-populations who might believe they were more exposed to sanctions if detected., Conclusions: Despite certain limitations of urine analysis as a reference, because of its poor detection of occasional users, our study is in favour of good accuracy of self-reported data on cannabis use, even among the military. However, our results, derived from a population study, do not enable any assumptions on the validity of self-reported data collected during individual testing procedures for the purpose of improving occupational safety.

Background: In the Armed Forces, knowledge about the causes of deaths is required in order to develop prevention strategies. This study presents the main characteristics of causes of deaths among male active-duty personnel in the French Armed Forces during the 2006-10 period and compares them with the general French male population., Methods: The data are provided by military public health surveillance. Comparisons of the specific mortality rates (MR) were performed using a Poisson regression. Standardized mortality ratios (SMRs) were calculated to compare mortality with the general French male population., Results: There were 1455 deaths among male active-duty personnel during the study period [MR: 100.9 per 100,000 person-years (PY); 95% confidence interval 95.7-106.1]. The 17-24 age group was characterized by violent deaths: transport accident (MR: 45.9 per 100,000 PY) and suicide (18.8 per 100 000 PY). Overall SMRs show significantly lower MR compared with the French national MR with the exception of SMR for transport accident and suicide in the 17-24 age group., Conclusions: There is a significantly lower deficit of mortality compared with the French male general population, reflecting a strong healthy worker effect. However, health promotion programmes should continue to put emphasis on transport accident especially among the 17-24 age group.

Objective: To ascertain the different profiles of alcohol and cannabis consumers in the French Army to improve prevention measures., Method: A representative sample of 990 French Army staff filled in self-questionnaires in 2006. A multiple correspondence analysis identified associations between consumption and consumer profiles., Results: The multiple correspondence analysis found three main consumer profiles: non-consumers (women and officers), moderate consumers (non-commissioned officers > 30-years old, single parents with children), and occasional multi-consumers (18-25-years-old enlisted males, who occasionally consumed cannabis and high levels of alcohol, also tobacco-addicts). Two minor profiles emerged: daily alcohol drinkers (men, > or = 30 years) and regular dependent cannabis users (identical profile to multi-consumers)., Conclusion: Our results favor targeting the youngest to prevent the risks of high alcohol intake and cannabis consumption and addiction linked to repeated binge drinking. Systematic questionnaires on consumption habits and addiction self-evaluations during medical consultations could lead to early care.

In 2006, a French Army unit reported 39 malaria cases among service persons returning from Ivory Coast. Thirty, including three serious forms, occurred after the return to France. The risk of post-return malaria was higher than the risk in Ivory Coast. Half of the imported cases had stopped post-return chemoprophylaxis early., (© 2010 International Society of Travel Medicine.)

To perform epidemiological surveillance during deployments, the French military health service has developed a real-time surveillance approach. The objective was to identify the benefits and problems of this approach. A prototype of real-time surveillance has been set up in French Guiana since 2004. Its permanent evaluation has allowed identifying strengths and weaknesses. The experience has permitted expansion of the concept to French forces in Djibouti and also development of a global approach for the whole French armed forces. Real-time surveillance has shown its usefulness for early warning during different real and simulated situations. Functional and architectural choices have permitted interoperability with allied nations. However, the information produced was only the first step of the diagnostic epidemiological situation followed by other investigations. This first step of development has highlighted the required complementarity with traditional epidemiological surveillance.

An integrated larval mosquito control program was carried out in Tiputa village on Rangiroa atoll of French Polynesia. Mosquito abundance before and after treatment was compared with the abundance in an untreated village. Mosquito larval habitats consisted of large concrete or polyurethane cisterns, wells, and 200-liter drums. Depending on the target species, larval habitat category, its configuration, and purpose (drinking consumption or not), abatement methods consisted of sealing the larval habitats with mosquito gauze, treating them with 1% Temephos, covering the water with a 10-cm thick layer of polystyrene beads or introducing fish (Poecillia reticulata Rosen & Bailey). All premises of the chosen village were treated and a health education program explained basic mosquito ecology and the methods of control. A community health agent was trained to continue the control program at the end of the experiment. Entomological indices from human bait collections and larval surveys indicated that mosquito populations were reduced significantly, compared with concurrent samples from the untreated control village, and that mosquito control remained effective for 6 mo after treatment. Effects of the treatment were noticed by the inhabitants in terms of a reduction in the number of mosquito bites. In the Polynesian context, such control programs may succeed in the long-term only if strong political decisions are taken at the village level, if a community member is designated as being responsible for maintaining the program, and if the inhabitants are motivated sufficiently by the mosquito nuisance to intervene.
