[Identifying and assisting sedentary patients: a practical guide]. / Identifier et accompagner les patient-es sédentaires : un guide pratique.

A sedentary lifestyle is a significant cardiovascular risk factor and increases premature mortality. Engaging in routine physical activity (PA) provides a wide range of health benefits. Accordingly, physical inactivity must be identified and sedentary patients supported systematically to achieve recommended levels of PA. The level of PA can be assessed by taking patients' history and using specific tools. Support begins by assessing PA contraindications and patients' level of motivation to change their lifestyle. Patients are then encouraged to adopt a more active lifestyle through tailored advice, and if necessary, referred to specialists with expertise in exercise medicine. This article details the key aspects of accompanying sedentary patients, to help healthcare professionals integrate them into their practice.

La sédentarité est un facteur de risque cardiovasculaire et de mortalité prématurée important et la pratique d'une activité physique (AP) procure un éventail large de bénéfices pour la santé. Elle doit donc être identifiée et adressée de manière systématique en consultation médicale. Le niveau d'AP peut être évalué par l'anamnèse et des outils spécifiques. L'accompagnement débute par une évaluation des contre-indications à la pratique d'une AP et du niveau de motivation des patient-es à changer leur mode de vie. Ceux-ci sont ensuite encouragé-es à adopter un mode de vie plus actif à travers des conseils adaptés, et si nécessaire, adressé-es à d'autres spécialistes. Cet article détaille les aspects clés de l'accompagnement des patient-es sédentaires afin d'aider les professionnel-les de la santé à les intégrer dans leur pratique.

Incidence of sexually transmitted infections and association with behavioural factors: Time-to-event analysis of a large pre-exposure prophylaxis (PrEP) cohort.

OBJECTIVES: Our objective was to obtain long-term data on the incidence of sexually transmitted infections (STIs) and their association with behavioural factors after widespread pre-exposure prophylaxis (PrEP) implementation. METHODS: This was a time-to-event analysis of a national PrEP cohort in Switzerland (SwissPrEPared study). Participants were people without HIV interested in taking PrEP with at least two STI screening visits. Primary outcomes were incidence rate of gonorrhoea, chlamydia, and syphilis. The association between behavioural factors and STI diagnosis was expressed using hazard ratios. We adjusted for testing frequency and calendar year. RESULTS: This analysis included 3907 participants enrolled between April 2019 and April 2022, yielding 3815.7 person-years of follow-up for gonorrhoea (15 134 screenings), 3802.5 for chlamydia (15 141 screenings), and 3858.6 for syphilis (15 001 screenings). The median age was 39 years (interquartile range [IQR] 32-47), 93.8% (n = 3664) identified as men who have sex with men (MSM). The incidence was 22.8 (95% confidence interval [CI] 21.3-24.4) per 100 person-years for gonorrhoea, 26.3 (95% CI 24.7-28.0) for chlamydia, and 4.4 (95% CI 3.8-5.1) for syphilis. Yearly incidence rates decreased between 2019 (all bacterial STIs: 81.6; 95% CI 59.1-109.9) and 2022 (all bacterial STIs: 49.8; 95% CI 44.6-55.3). Participants reporting chemsex substance use were at higher risk of incident STIs, as were those reporting multiple sexual partners. Younger age was associated with a higher risk of gonorrhoea and chlamydia. CONCLUSIONS: Incidence rates of bacterial STIs decreased over time. Young MSM, those with multiple partners, and those using chemsex substances were at increased risk of STIs.

[Teaching health equity in the French-speaking part of Switzerland : inventory in 2023]. / Enseignements sur l'équité en santé en Suisse romande : état des lieux en 2023.

The theme of health equity was for a long time absent or little addressed in the pre- and postgraduate teaching programs of universities and training university hospitals in Switzerland. This gap has gradually been filled by the development and provision of structured teaching on health equity, adapted to the needs of their target audiences. This article aims to highlight a selection of teachings that have emerged in recent years in the French-speaking part of Switzerland.

La thématique de l'équité en santé a été pendant longtemps absente ou peu abordée dans les programmes d'enseignement pré et post-gradué des universités et établissements hospitaliers de formation en Suisse. Cette lacune a été progressivement comblée par le développement et la mise à disposition de formations structurées portant sur l'équité en santé, adaptées aux besoins de leurs publics cibles. Cet article vise à mettre en avant une sélection d'enseignements qui ont vu le jour ces dernières années en Suisse romande.

[I-CARE: a pioneering e-learning training program on LGBTIQ+ health]. / I-CARE : une formation pionnière par apprentissage en ligne sur la santé des personnes LGBTIQ.

While several recent studies suggest that approximately 1 in 6 young people in Switzerland are part of the rainbow diversity, a high proportion of health professionals have never had a course on LGBTIQ+ (lesbian, gay, bisexual, transgender, intersex, queer, questioning or other) health. This situation leads to significant gaps in the medical care of LGBTIQ+ persons as well as difficulties in accessing equitable, culturally appropriate and quality care. This article presents the ambitious and novel e-learning project I-CARE (Improving Care and Access for Rainbow Equity) which should contribute, from the end of this year, to filling the current gaps in the undergraduate and continuing education of health professionals.

Alors que plusieurs études récentes suggèrent qu'environ 1 jeune sur 6 fait partie de la diversité arc-en-ciel en Suisse, une proportion élevée des professionnel-les de santé n'a jamais eu de cours sur la santé des personnes LGBTIQ+ (lesbiennes, gays, bisexuelles, transgenres, intersexuées, queers, en questionnement ou autres). Cette situation entraîne d'importantes lacunes dans la prise en charge médicale des personnes LGBTIQ+, ainsi qu'une difficulté d'accès à des soins équitables, culturellement appropriés et de qualité. Cet article présente l'ambitieux et inédit projet de formation par apprentissage en ligne I-CARE (Improving Care and Access for Rainbow Equity) qui devra contribuer, à partir de la fin de cette année, à combler les lacunes actuelles dans la formation prégraduée et continue des professionnel-les de santé.

[COVID-19 screening strategy in workplaces in the canton of Vaud: what lessons?] / Stratégie de dépistage du Covid-19 dans les entreprises vaudoises : quels enseignements ?

Repetitive screening in enterprises was one of the measures recommended in Switzerland in the fight against COVID-19. In the canton of Vaud, 70 companies participated in the program, 73 % of which were small and medium-sized enterprises. The SARS-CoV-2 positivity rate was 0.07 % out of 70'105 tests performed. The impossibility of teleworking and the reduction of transmission were the main motivations for joining the program. The facilitating elements were the availability of the Cantonal Medical Office, the existence of a starter kit and the support of the hierarchy within the companies. The main obstacles were the arrival of vaccination, the multiplicity of screening providers and the workload. The program was a pragmatic action tool for companies rather than a population-based strategy.

Le dépistage en entreprise était une des mesures de lutte contre l'épidémie de Covid-19 promues par la Confédération. Dans le canton de Vaud, 70 entreprises ont participé au programme, dont 73 % de petites et moyennes entreprises. Le taux de positivité au SARS-CoV-2 a été de 0,07 % sur 70 105 tests réalisés. L'impossibilité du télétravail et la réduction de la transmission ont été les principales motivations d'adhésion. Les éléments facilitateurs ont été la disponibilité de l'Office du médecin cantonal, l'existence d'un starter kit et le soutien de la hiérarchie au sein des entreprises. Les freins principaux ont été l'arrivée de la vaccination, la multiplicité des prestataires de dépistage et la charge de travail. Le programme a représenté un outil d'action pragmatique pour les entreprises plutôt qu'une stratégie à visée populationnelle.

Detecting and describing heterogeneity in health care cost trajectories among asylum seekers.

BACKGROUND: The mechanism underlying the health care cost trajectories among asylum seekers is not well understood. In the canton of Vaud in Switzerland, a nurse-led health care and medical Network for Migrant Health ("Réseau santé et migration" RESAMI) has established a health care model focusing on the first year after arrival of asylum seekers, called the "community health phase". This model aims to provide tailored care and facilitate integration into the Swiss health care system. The aim of this study is to explore different health care cost trajectories among asylum seekers during this phase and identify the associated factors. METHODS: We detected different patterns of health care cost trajectories using time-series clustering of longitudinal data of asylum seekers in the canton of Vaud in Switzerland. These data included all adult asylum seekers and recipients of emergency aid who entered the canton between 2012 and 2015 and were followed until 2018. The different clusters of health care cost trajectories were then described using a multinomial logistic regression model. RESULTS: We identified a concave, an upward trending, and a downward trending cluster of health care cost trajectories with different characteristics being associated with each cluster. The likelihood of being in the concave cluster is positively associated with coming from the Eastern Mediterranean region or Africa rather than Europe and with a higher share of consultations with an interpreter. The likelihood of being in the upward trending cluster, which accrued the highest costs, is positively associated with 20-24-year-olds rather than older individuals, coming from Europe than any other region and having a mental disorder. In contrast to the other two clusters, the likelihood of being in the downward trending cluster is positively associated with having contacted the RESAMI network within the first month after arrival, which might indicate the potential of early intervention. It is also positively associated with older age and living in a group lodge. CONCLUSIONS: Asylum seekers are heterogeneous in terms of health care cost trajectories. Exploring these differences can help point to possible ways to improve the care and supporting services provided to asylum seekers. Our findings could indicate that early and patient-centered interventions might be well-suited to this aim.

Changes in mental and sexual health among MSM using HIV pre-exposure prophylaxis during the SARS-CoV-2 pandemic: longitudinal analysis of the SwissPrEPared cohort study.

BACKGROUND: Changes in mental and sexual health among men having sex with men (MSM) due to the SARS-CoV-2 pandemic remain unclear. METHODS: Design: Longitudinal analysis of an ongoing, multicentre, pre-exposure prophylaxis (PrEP) cohort (NCT03893188) in Switzerland. Participants: HIV-negative MSM aged ≥18 who completed at least one questionnaire before and one after the start of the SARS-CoV-2 pandemic. Outcomes: Primary: mental health, defined as anxiety and depression scores assessed by the Patient Health Questionnaire-4. Secondary: sexual behaviour, well-being, PrEP use and disruption of care. Outcomes were assessed over seven periods corresponding to different SARS-CoV-2 prevention measures in Switzerland. We performed pairwise comparisons between periods (Wilcoxon signed rank test). RESULTS: Data from 1,043 participants were included. Whilst anxiety scores remained stable over time, depression scores worsened in the second wave and the second lockdown period compared to pre-pandemic scores. This was confirmed by pairwise comparisons (pre-SARS-CoV-2/second wave and pre-SARS-CoV-2/second lockdown: p <0.001). Downward trends in sexual activity,sexualized substance use, and a switch from daily to "event-driven" PrEP were found. Disruption of care affected 42.6% (790/1856) of daily PrEP users' follow-up visits. CONCLUSION: In this longitudinal analysis of a PrEP cohort enrolling MSM, depression scores worsened in the second wave and the second lockdown compared to the pre-pandemic period.

Care and cost trajectories of asylum seekers in a nurse-led, patient centered, care network in Switzerland.

BACKGROUND: Switzerland, with its decentralized health system, has seen the emergence of a variety of care models to meet the complex needs of asylum seekers. A network of public and private providers was designed in the canton Vaud, in which a nurse-led team acts as a first contact point to the health system and provides health checks, preventive care, and health education to this population. In addition, the service plays a case management role for more complex and vulnerable patients. While the network has been examined from a clinical angle, we provide the first descriptive evidence on the care and cost trajectories of asylum seekers in the canton. METHODS: We used routinely collected administrative, patient-level data in a Swiss region responsible for 10% of the asylum seekers in the country. We extracted data on all asylum seekers aged 18 or older who entered the network between 2012 and 2015. The data covered all healthcare costs during the period until they left the network, either because they were granted residence, they left the country, or until 31 December 2018. We estimated random effects regression models for costs and consultations within and outside the network for each month of stay in the network. We investigated language barriers in access to care by stratifying the analysis between patients who spoke one of the official Swiss languages or English and patients who did not speak any of these languages. PRINCIPAL FINDINGS: We found that both overall health care costs and contacts with the nurse-led team were relatively high during the first year of stay. Asylum seekers then progressively integrated into the regular health system. Individuals who did not speak the language generally had more contacts with the network and fewer contacts outside. CONCLUSIONS: In this exploratory study, we observe a transition from nurse-led specific care with frequent contacts to care in the regular health system. This leads us to generate the hypothesis that a nurse-led, patient-centered care network for asylum seekers can play an important role in providing primary care during the first year after their arrival and can subsequently help them navigate autonomously within the conventional healthcare system.

Epidemiology of sexually transmitted infections among female sex workers in Switzerland: a local, exploratory, cross-sectional study.

Female sex workers are often considered highly vulnerable to sexually transmitted infections (STIs). However, data on STI epidemiology in female sex workers are lacking in Switzerland. Our main goal was to evaluate the prevalence of six STIs (human immunodeficiency virus [HIV], hepatitis B, hepatitis C, Chlamydia trachomatis, Neisseria gonorrhoeae and syphilis) among local female sex workers in Lausanne. A local, exploratory, cross-sectional study was conducted on a convenience sample of adult (≥18 years) Female sex workers in Lausanne, Switzerland, from 1 April 2015 to 31 December 2016. female sex workers who worked in street sex venues, massage parlours and brothels were approached for recruitment by a local non-governmental organisation. They were then invited to present at the Lausanne University Hospital, where they were offered a free STI screening and hepatitis A and B vaccination. We enrolled 96 female sex workers. They were predominantly undocumented immigrants (60%) from Africa and Eastern Europe with no health insurance; only one participant (1%) was Swiss born. During the study, 15 (16%; 95% confidence interval [CI] 9–23%) participants were newly confirmed to have an STI: six (6%; 95% CI 1–11%) had C. trachomatis, five (5%; 95% CI 0.6-9%) latent syphilis and four (4%; 95% CI 0.1–8%) hepatitis B (three with chronic active infection and one with past exposure). No human immunodeficiency virus (HIV) infections were newly diagnosed among the participants. Nineteen (20%) of the female sex workers were already vaccinated against hepatitis B, and 73 (76%) initiated vaccination against hepatitis A and hepatitis B during the study. Forty-four (46%) of the female sex workers required translation and assistance from social services.

Medical students' knowledge of and attitudes towards LGBT people and their health care needs: Impact of a lecture on LGBT health.

OBJECTIVES: Lesbian, gay, bisexual, and transgender (LGBT) adolescents have specific health care needs and are susceptible to health care disparities. Lack of skills and knowledge on the part of health care providers have a negative effect on their access to care and health outcomes. This study 1) explores the knowledge and attitudes of medical students regarding LGBT people, and 2) assesses the impact of a one-hour lecture targeting adolescent LGBT health needs. METHODS: Fourth-year medical students attended a compulsory one-hour lecture on sexual orientation and gender identity development in adolescence, highlighting health issues. We created a questionnaire with items to elicit students' knowledge and attitudes about LGBT health issues. Students were invited to complete this questionnaire online anonymously one week before the lecture and one month after the lecture. RESULTS: Out of a total of 157 students, 107 (68.2%) responded to the pre-intervention questionnaire and 96 (61.1%) to the post-intervention questionnaire. A significant proportion-13.7% of all respondents-identified as LGBT or questioning. Our results show that most medical students already show favorable attitudes towards LGBT people and a certain degree of knowledge of LGBT health needs. They demonstrated a large and significant increase in knowledge of LGBT health issues one month after the lecture. DISCUSSION: A single one-hour lecture on sexual orientation and LGBT health issues may increase knowledge among medical students. Medical students and professionals should receive such training to increase their knowledge about LGBT patients as it, together with favorable attitudes, has the potential to improve health outcomes among this vulnerable population.

[Physical activity counseling Referring to an adapted physical activity specialist†: example of the Step by Step+ project]. / Conseil en activité physique - Sa délégation vers une spécialiste en activité physique adaptée†: le projet Pas à Pas.

The health benefits of regular physical activity are undeniable. There is a dose-response relationship between total physical activity and health outcomes, and thus every opportunity should be seized to exercise more. Among the methods used to increase the level of physical activity, physical activity counselling delivered in clinical practice is effective. The Pas à Pas+ project presented in this article allows to extend the advice from the healthcare professional and to lead up the patient to a physically more active lifestyle, providing a support in physical activity on prescription. There are several -challenges that need to be addressed in order to anchor definitely physical activity counselling and its delegation to professionals in adapted physical activity in the healthcare setting.

Les bénéfices d'une activité physique régulière pour la santé sont indéniables. Il existe une relation dose-réponse entre la quantité totale d'activités physiques pratiquées et la santé, si bien que chaque occasion doit être saisie pour bouger davantage. Parmi les moyens permettant d'augmenter le niveau d'activité physique de la population, le conseil réalisé en pratique clinique est ­efficace. Le projet Pas à Pas+ présenté dans cet article permet de prolonger le conseil du ou de la professionnelle de santé et d'accompagner concrètement le ou la patiente vers un mode de vie plus actif à travers une prestation de suivi en activité physique sur délégation médicale. Plusieurs défis doivent être relevés afin d'ancrer solidement dans le domaine des soins le conseil en ­matière d'activité physique et sa délégation vers des profes­sionnelles de l'activité physique adaptée.

'Break the Chains 2015' community-based HIV prevention campaign for men who have sex with men in Switzerland: non-randomised evaluation and cost analysis.

OBJECTIVES: To study the implementation, effects and costs of Break the Chains, a community-based HIV prevention campaign for men who have sex with men (MSM) in Switzerland, from March to May 2015, which aimed to reduce early HIV transmission by promoting the campaign message to adopt short-term risk reduction followed by HIV testing. DESIGN: Non-randomised evaluation and cost analysis. SETTING: Gay venues in 11 of 26 cantons in Switzerland and national online media campaign. PARTICIPANTS: MSM in online surveys (precampaign n=834, postcampaign n=688) or attending HIV testing centres (n=885); campaign managers (n=9); and campaign staff (n=38) or further intermediaries (n=80) in an online survey. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome measure was the proportion of MSM at risk of HIV acquisition or transmission who adhered to the campaign message. Secondary outcomes were postcampaign test uptake, knowledge about HIV primary infection and sense of belonging to the gay community. RESULTS: Campaign staff estimated that they contacted 17 145 MSM in 11 cantons. Among 688 respondents to the postcampaign survey, 311 (45.2%) were categorised as MSM at risk. Of 402/688 (58.5%) MSM who had heard about Break the Chains 2015, MSM categorised as being at risk were less likely to report adherence to the campaign message than MSM not at risk (adjusted OR 0.24; 95% CI 0.14 to 0.42). Twenty per cent of MSM with a defined risk of HIV acquisition or transmission who adopted risk reduction declared having done so because of the campaign. Costs for one MSM at risk to adhere to the campaign message were estimated at USD purchasing power parity 36-55. The number of HIV tests in the month after the campaign was twice the monthly average. CONCLUSION: Break the Chains increased HIV testing, implying that community-based campaigns are useful HIV prevention strategies for MSM. Additional interventions are needed to reach MSM at the highest risk of infection more effectively.

Biomedical risk assessment as an aid for smoking cessation.

BACKGROUND: A possible strategy for increasing smoking cessation rates could be to provide smokers with feedback on the current or potential future biomedical effects of smoking using, for example, measurement of exhaled carbon monoxide (CO), lung function, or genetic susceptibility to lung cancer or other diseases. OBJECTIVES: The main objective was to determine the efficacy of providing smokers with feedback on their exhaled CO measurement, spirometry results, atherosclerotic plaque imaging, and genetic susceptibility to smoking-related diseases in helping them to quit smoking. SEARCH METHODS: For the most recent update, we searched the Cochrane Tobacco Addiction Group Specialized Register in March 2018 and ClinicalTrials.gov and the WHO ICTRP in September 2018 for studies added since the last update in 2012. SELECTION CRITERIA: Inclusion criteria for the review were: a randomised controlled trial design; participants being current smokers; interventions based on a biomedical test to increase smoking cessation rates; control groups receiving all other components of intervention; and an outcome of smoking cessation rate at least six months after the start of the intervention. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. We expressed results as a risk ratio (RR) for smoking cessation with 95% confidence intervals (CI). Where appropriate, we pooled studies using a Mantel-Haenszel random-effects method. MAIN RESULTS: We included 20 trials using a variety of biomedical tests interventions; one trial included two interventions, for a total of 21 interventions. We included a total of 9262 participants, all of whom were adult smokers. All studies included both men and women adult smokers at different stages of change and motivation for smoking cessation. We judged all but three studies to be at high or unclear risk of bias in at least one domain. We pooled trials in three categories according to the type of biofeedback provided: feedback on risk exposure (five studies); feedback on smoking-related disease risk (five studies); and feedback on smoking-related harm (11 studies). There was no evidence of increased cessation rates from feedback on risk exposure, consisting mainly of feedback on CO measurement, in five pooled trials (RR 1.00, 95% CI 0.83 to 1.21; I2 = 0%; n = 2368). Feedback on smoking-related disease risk, including four studies testing feedback on genetic markers for cancer risk and one study with feedback on genetic markers for risk of Crohn's disease, did not show a benefit in smoking cessation (RR 0.80, 95% CI 0.63 to 1.01; I2 = 0%; n = 2064). Feedback on smoking-related harm, including nine studies testing spirometry with or without feedback on lung age and two studies on feedback on carotid ultrasound, also did not show a benefit (RR 1.26, 95% CI 0.99 to 1.61; I2 = 34%; n = 3314). Only one study directly compared multiple forms of measurement with a single form of measurement, and did not detect a significant difference in effect between measurement of CO plus genetic susceptibility to lung cancer and measurement of CO only (RR 0.82, 95% CI 0.43 to 1.56; n = 189). AUTHORS' CONCLUSIONS: There is little evidence about the effects of biomedical risk assessment as an aid for smoking cessation. The most promising results relate to spirometry and carotid ultrasound, where moderate-certainty evidence, limited by imprecision and risk of bias, did not detect a statistically significant benefit, but confidence intervals very narrowly missed one, and the point estimate favoured the intervention. A sensitivity analysis removing those studies at high risk of bias did detect a benefit. Moderate-certainty evidence limited by risk of bias did not detect an effect of feedback on smoking exposure by CO monitoring. Low-certainty evidence, limited by risk of bias and imprecision, did not detect a benefit from feedback on smoking-related risk by genetic marker testing. There is insufficient evidence with which to evaluate the hypothesis that multiple types of assessment are more effective than single forms of assessment.

Interprofessional collaboration and diabetes care in Switzerland: A mixed-methods study.

To face the increasing prevalence of diabetes in Switzerland, a cantonal programme has been implemented. One of its goals is to promote collaborative approaches among healthcare professionals (HCPs). The objectives of the current study were to examine HCPs' perceptions about the collaboration they experience in diabetes care and to determine whether perceptions differed among professional groups. A mixed-methods study was conducted. First, a total of 332 HCPs comprising diabetes specialists and non-specialists participated by completing a questionnaire on interprofessional collaboration. Focus groups were then led in order to deepen the understanding and complement the interpretation of quantitative results. Quantitative results showed a perception of a moderate level of collaboration. Mean scores for specialists were systematically worse than those of non-specialists and more prominently in the "level of conflict dimension," which means that specialists generally perceived a lower level of collaboration and a higher level of possible conflict associated with it. Qualitative results highlighted the vagueness in role definition and emphasised a form of reluctance by general physicians to collaborate with specialists, as the physicians felt that they were losing their responsibilities. The findings suggest that it is not the need to collaborate that encourages HCPs involved in collaborative schemes to desire or to know how to successfully initiate, promote, or conduct interprofessional collaboration. This study highlights the important perceptions about collaboration that could be taken into account when planning future collaborative programmes.

[Exercise-referral to a specialist in adapted physical activity (APA) : a pilot project]. / Délégation médicale vers un(e) spécialiste en activité physique adaptée (APA) : un projet pilote.

Family physicians have a key role in the promotion of physical activity, in particular in identifying and counseling persons who have a sedentary lifestyle. Some patients could benefit from intensive individual counseling. Physicians are often not aware of all physical activity promotion activities in the community that they could recommend their patients. In a pilot study, we have tested and adapted the referral of patients from family physicians to specialists in adapted physical activity (APAs). APAs are trained to assess and guide persons towards physical activities adapted to their needs and pathologies and thus towards an increase in physical activity. Pilot data suggest that, while few patients were oriented to the APAs in the pilot project, family physicians appreciate the possibility of collaborating with the APAs.

Les médecins de famille ont un rôle clé pour la promotion de l'activité physique, en particulier pour identifier et conseiller des personnes sédentaires. Certains patients pourraient bénéficier d'un accompagnement individuel plus intensif. Les offres d'activité physique dans la communauté ne sont pas toujours connues des médecins. Dans une étude pilote, nous avons testé et adapté la délégation de patients par des médecins de famille vers des spécialistes en activité physique adaptée (APAs). Les APAs sont formés à évaluer et accompagner des personnes vers des activités physiques adaptées à leurs besoins et pathologies et d'ainsi permettre une augmentation du niveau d'activité physique. Les données pilotes suggèrent que, si peu de patients ont été orientés vers les APAs, les médecins apprécient la possibilité de collaborer avec un APAs.

Leptin and smoking cessation: secondary analyses of a randomized controlled trial assessing physical activity as an aid for smoking cessation.

BACKGROUND: Smokers have a lower body weight compared to non-smokers. Smoking cessation is associated with weight gain in most cases. A hormonal mechanism of action might be implicated in weight variations related to smoking, and leptin might be implicated. We made secondary analyses of an RCT, with a hypothesis-free exploratory approach to study the dynamic of leptin following smoking cessation. METHODS: We measured serum leptin levels among 271 sedentary smokers willing to quit who participated in a randomized controlled trial assessing a 9-week moderate-intensity physical activity intervention as an aid for smoking cessation. We adjusted leptin for body fat levels. We performed linear regressions to test for an association between leptin levels and the study group over time. RESULTS: One year after smoking cessation, the mean serum leptin change was +3.23 mg/l (SD 4.89) in the control group and +1.25 mg/l (SD 4.86) in the intervention group (p of the difference < 0.05). When adjusted for body fat levels, leptin was higher in the control group than in the intervention group (p of the difference < 0.01). The mean weight gain was +2.91 (SD 6.66) Kg in the intervention and +3.33 (SD 4.47) Kg in the control groups, respectively (p not significant). CONCLUSIONS: Serum leptin levels significantly increased after smoking cessation, in spite of substantial weight gain. The leptin dynamic might be different in chronic tobacco users who quit smoking, and physical activity might impact the dynamic of leptin in such a situation. Clinical trial registration number: NCT00521391.

[Physical activity promotion in 0-6 years old children]. / Pédiatrie 3. Formation continue: promotion du mouvement et de l'activité physique chez les 0-6 ans.

Sedentary lifestyle in children is increasing at an alarming rate. Now, promotion of physical activity by health professionals is a promising way. To support childhood specialists in this role, a transdisciplinary training is being developped.
