RESUMO
BACKGROUND: Few studies evaluated the use of Household Disinfectant and Cleaning Products (HDCPs) during the COVID-19 pandemic, but no population-based cohorts used longitudinal data. We studied changes in HDCPs during the first lockdown, based on longitudinal data from the French population-based NutriNet-Santé and CONSTANCES cohorts. METHODS: Based on standardized questionnaires on household cleaning tasks in 2018-2019 and around the first lockdown in France (March17-May3 2020), we compared the duration of weekly use of HDCPs (< 1 day/week, < 10 min/week; 10-30 min/week; > 30 min/week) and the household cleaning help (yes/no) before and during the lockdown period by Bhapkar and McNemar's tests. Moreover, we assessed self-reported changes in the frequency of HDCPs during the lockdown from before (unchanged/increased). RESULTS: Analyses were carried on 31,105 participants of NutriNet-Santé (48 years, 75% women, 81% ≥ high school diploma) and 49,491 of CONSTANCES (47 years, 51% women, 87% ≥ high school diploma). During the lockdown, compared with 2018-2019, duration of HDCPs use increased (> 30 min; NutriNet-Santé: 44% versus 18%; CONSTANCES: 63% versus 16%) and household help decreased (NutriNet-Santé: 5% versus 40%; CONSTANCES: 3% versus 56%). Regarding the frequency of HDCPs use, 55% of participants of NutriNet-Santé (57% women/49% men) and 83% of CONSTANCES (86% women/81% men) reported an increased use since the beginning of the lockdown, significantly higher among women (p < 0.0001). CONCLUSIONS: The frequency and duration of weekly use of HDCPs has significantly increased since the pandemic. As the use of HDCPs is associated with health issues, further studies are now needed to evaluate the potential health impacts of these changes.

Importance: Most observational studies examining the association between hearing loss (HL) and cognitive impairment used subjective measures of hearing and addressed only one dimension of cognition, and very few investigated the potential benefit of hearing aids (HAs). Objective: To evaluate objectively measured HL and several dimensions of cognition and estimate the association with HA use. Design, Setting, and Participants: A cross-sectional analysis of the CONSTANCES cohort study, which recruited participants from January 1, 2012, to December 31, 2020, was conducted. Participants were a representative sample of adults (age, 45-69 years) with audiometric data and cognitive evaluation from 21 preventive health centers in France. Data analysis was conducted from April 1 to September 15, 2023. Exposure: The main exposure was HL, which was defined by a pure-tone average in the best ear higher than 20 dB hearing level for mild loss and 35 dB hearing level for disabling loss. Secondary exposure was self-reported HA use. Main Outcomes and Measures: Cognition was evaluated at study inclusion by a standardized battery of 5 cognitive tests conducted by trained neuropsychologists. A global cognitive score was computed from principal component analysis and global cognitive impairment was defined as having a score less than or equal to the 25th percentile of the distribution. Results: The study population included 62â¯072 participants with audiometric data (mean [SD] age, 57.4 [7] years; 52% women). Overall, 38% (n = 23â¯768) had mild HL, 10% (n = 6012) had disabling HL, and 3% (n = 1668) were HA users. In multivariable analyses, mild HL (odds ratio [OR], 1.10; 95% CI, 1.05-1.15) and disabling HL (OR, 1.24; 95% CI, 1.16-1.33) were associated with greater global cognitive impairment. The odds of cognitive impairment did not differ significantly between all participants with HA use and participants with disabling HL without HAs (OR, 0.94; 95% CI, 0.83-1.07), except among participants with depression (OR, 0.62; 95% CI, 0.44-0.88). Conclusions and Relevance: In this cohort study, an association between the severity of HL and global cognitive impairment was found. The use of HAs was not associated with significantly lower odds of cognitive impairment. The findings suggest that it may be useful to monitor cognitive function in middle-aged individuals with HL.

BACKGROUND: There is a strong association between obstructive sleep apnea and hypertension, but the effects of obstructive sleep apnea symptoms on the risk of incident hypertension are not well documented. The aim of this prospective study was to examine whether snoring and sleepiness are associated with incident hypertension. METHODS: Data from the French population-based CONSTANCES cohort were analyzed. Normotensive participants, aged 18 to 69 years, were included between 2012 and 2016 and screened for snoring, morning fatigue, and daytime sleepiness in 2017 using items of the Berlin Questionnaire. We used Cox models, adjusted for multiple potential confounders, including body mass index, baseline blood pressure, sleep duration, and depressive symptoms, to compute hazards ratios of incidentally treated hypertension. RESULTS: Among 34â 727 subjects, the prevalence of self-reported habitual snoring, morning fatigue, and excessive daytime sleepiness (≥3× a week for each) was 23.6%, 16.6%, and 19.1%, respectively. During a median follow-up of 3.1 years (interquartile range, 3.0-3.5), the incidence of treated hypertension was 4.1%. The risk of de novo treated hypertension was higher in participants who reported habitual snoring (adjusted hazard ratio, 1.17 [95% CI, 1.03-1.32]) and excessive daytime sleepiness (adjusted hazard ratio, 1.42 [95% CI, 1.24-1.62]), and increased with the weekly frequency of symptoms, with a dose-dependent relationship (Ptrend≤0.02 for all symptoms). CONCLUSIONS: Self-reported snoring and excessive daytime sleepiness are associated with an increased risk of developing hypertension. Identification of snoring and daytime sleepiness may be a useful public health screening tool in primary care for hypertension prevention.
RESUMO
The demographical history of France remains largely understudied despite its central role toward understanding modern population structure across Western Europe. Here, by exploring publicly available Europe-wide genotype datasets together with the genomes of 3234 present-day and six newly sequenced medieval individuals from Northern France, we found extensive fine-scale population structure across Brittany and the downstream Loire basin and increased population differentiation between the northern and southern sides of the river Loire, associated with higher proportions of steppe vs. Neolithic-related ancestry. We also found increased allele sharing between individuals from Western Brittany and those associated with the Bell Beaker complex. Our results emphasise the need for investigating local populations to better understand the distribution of rare (putatively deleterious) variants across space and the importance of common genetic legacy in understanding the sharing of disease-related alleles between Brittany and people from western Britain and Ireland.

BACKGROUND: Lung cancer risk prediction models might efficiently identify individuals who should be offered lung cancer screening. However, their performance has not been comprehensively evaluated in Europe. We aimed to externally validate and evaluate the performance of several risk prediction models that predict lung cancer incidence or mortality in prospective European cohorts. METHODS: We analysed 240â137 participants aged 45-80 years with a current or former smoking history from nine European countries in four prospective cohorts from the pooled database of the Lung Cancer Cohort Consortium: the Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study (Finland), the Nord-Trøndelag Health Study (Norway), CONSTANCES (France), and the European Prospective Investigation into Cancer and Nutrition (Denmark, Germany, Italy, Spain, Sweden, the Netherlands, and Norway). We evaluated ten lung cancer risk models, which comprised the Bach, the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial 2012 model (PLCOm2012), the Lung Cancer Risk Assessment Tool (LCRAT), the Lung Cancer Death Risk Assessment Tool (LCDRAT), the Nord-Trøndelag Health Study (HUNT), the Optimized Early Warning Model for Lung Cancer Risk (OWL), the University College London-Death (UCLD), the University College London-Incidence (UCLI), the Liverpool Lung Project version 2 (LLP version 2), and the Liverpool Lung Project version 3 (LLP version 3) models. We quantified model calibration as the ratio of expected to observed cases or deaths and discrimination using the area under the receiver operating characteristic curve (AUC). For each model, we also identified risk thresholds that would screen the same number of individuals as each of the US Preventive Services Task Force 2021 (USPSTF-2021), the US Preventive Services Task Force 2013 (USPSTF-2013), and the Nederlands-Leuvens Longkanker Screenings Onderzoek (NELSON) criteria. FINDINGS: Among the participants, 1734 lung cancer cases and 1072 lung cancer deaths occurred within five years of enrolment. Most models had reasonable calibration in most countries, although the LLP version 2 overpredicted risk by more than 50% in eight countries (expected to observed ≥1·50). The PLCOm2012, LCDRAT, LCRAT, Bach, HUNT, OWL, UCLD, and UCLI models showed similar discrimination in most countries, with AUCs ranging from 0·68 (95% CI 0·59-0·77) to 0·83 (0·78-0·89), whereas the LLP version 2 and LLP version 3 showed lower discrimination, with AUCs ranging from 0·64 (95% CI 0·57-0·72) to 0·78 (0·74-0·83). When pooling data from all countries (but excluding the HUNT cohort), 33·9% (73 313 of 216 387) of individuals were eligible by USPSTF-2021 criteria, which included 74·8% (1185) of lung cancers and 76·3% (730) of lung cancer deaths occurring over 5 years. Fewer individuals were selected by USPSTF-2013 and NELSON criteria. After applying thresholds to select a population of equal size to USPSTF-2021, the PLCOm2012, LCDRAT, LCRAT, Bach, HUNT, OWL, UCLD, and UCLI, models identified 77·6%-79·1% of future cases, although they selected slightly older individuals compared with USPSTF-2021 criteria. Results were similar for USPSTF-2013 and NELSON. INTERPRETATION: Several lung cancer risk prediction models showed good performance in European countries and might improve the efficiency of lung cancer screening if used in place of categorical eligibility criteria.

Trihalomethanes (THMs) and nitrate are widespread chemicals in drinking water. Chronic exposure has been associated with increased cancer risk despite inconclusive evidence, partly due to the challenges in long-term exposure assessment and potential exposure misclassification. We estimated concentrations of nitrate and THMs in drinking water using a public regulatory monitoring database (SISE-Eaux) for CONSTANCES, a French population-based prospective cohort. We obtained 26,322,366 measurements of drinking water parameters from 2000 to 2020. We excluded missing, implausible and duplicated measurements; we corrected or imputed missing geocodes of sampling locations; we calculated the annual median concentration of nitrate and THMs by surveillance area. To predict missing annual median concentrations, linear mixed models with random intercept using surveillance area as a clustering variable were developed for each region for nitrate and the four THM components (chloroform, chlorodibromomethane, bromodichloromethane and bromoform) separately. Concentrations in the nearest surveillance area from the household were merged per year among 75,462 participants with residential history geocoded for 2000-2020. Estimated concentrations resulting from this approach were compared with measured concentrations in 100 samples collected in Paris, Rennes and Saint-Brieuc in 2021. Median annual concentrations of total THMs and nitrate at study participants' homes for 2000-2020 were, respectively, 15.7 µg/l (IQR: 15.2) and 15.2 mg/l (IQR: 20.8). Among these, 35% were based on measurements for nitrate (16% for THMs), 44% (46%) were predicted using on linear mixed models, and 21% (38%) were based on distribution unit median values. Conditional R2 predictive models ranged from 0.71 to 0.91 (median: 0.85) for nitrate, and from 0.48 to 0.80 for THMs (median: 0.68). These concentrations will allow future association analyses with risk of breast and colorectal cancer. Our cleaning process introduced here could be adapted to other large drinking water monitoring data.

BACKGROUND: To measure the association of prematurity and non-preterm low birth weight (LBW) with several long-term health outcomes. METHODS: We selected adult participants from the Constances cohort. Associations between preterm birth (<37 weeks versus ≥37 weeks) and outcomes were measured using modified Poisson regression with adjustment for participant age and parental history. We used the same modeling methods to measure the association between LBW (i.e.,
RESUMO
We quantified the extent to which the association between education and fast walking speed (FWS) is explained by 17 mediators (cardiovascular risk factors/diseases, comorbidities, health behaviours, socio-professional characteristics, cognition), and examined whether mediators interact with education, in favor of a reserve hypothesis. Cross-sectional analyses are based on Constances (population-based study of French adults 45-69y). 3m-FWS was measured using photoelectric cells. Education was categorized as lower/higher. After multiple imputation of missing values, we used counterfactual mediation models for multiple mediators allowing for education×mediator interactions, to estimate the total effect (TE), total indirect effect (TIE), and mediated interaction (IMD) of lower education on FWS. Analyses are based on 71,222 participants (52.6% women; mean age=57.2y; 27.2% higher education; mean FWS=180.2cm/s). In joint mediation analyses, the TE of lower education was -8.19cm/s (95% confidence interval [CI]=-8.87;-7.51), with a TIE of -5.76cm/s (95%CI=-6.10;-5.41; proportion mediated=70.3%, 95%CI=65.6;75.0). The IMD was negative (-2.52, 95%CI=-3.31;-1.72); 30.8% of the TE and 43.8% of the TIE were attributable to the IMD. Several mediators explain a large part of the association between lower education and slower FWS. The detrimental effect of mediators was more pronounced in participants with lower than in those with higher education, in agreement with a reserve hypothesis.
RESUMO
OBJECTIVE: Pituitary stalk interruption syndrome (PSIS) is a rare cause of congenital hypopituitarism. Limited data exist on the gonadotropic status and fertility of adult women with PSIS. Our study aims to describe pubertal development and the evolution of gonadotropic function and fertility in adult women with PSIS. DESIGN: A retrospective multicentric French study. METHODS: We described gonadotropic function in 56 adult women with PSIS from puberty onward. We compared live birth rates per woman with PSIS with age-matched controls from the large French epidemiological cohort (CONSTANCES). Additionally, we assessed height, body mass index (BMI), blood pressure, other metabolic parameters, and socioeconomic status. RESULTS AND CONCLUSIONS: Among 56 women with PSIS, 36 did not experience spontaneous puberty. Of these, 13 underwent ovarian stimulation, resulting in 7 women having a total of 11 children. In the subgroup with spontaneous puberty (n = 20), 4 had a total of 8 pregnancies, while 6 developed secondary gonadotropic deficiency. Women with PSIS had fewer children than controls (0.33 vs 0.63, P = .04). Median height was also lower (160.5 vs 165.0â cm, P < .0001). Although mean blood pressure was lower in women with PSIS compared with controls (111.3/65.9 ± 11.2/8.1 vs 118.7/72.1 ± 10.1/7.7â mmHg, P < .001), there were no significant differences in other metabolic parameters, notably BMI and lipid profile. Employment/academic status was not different in the 2 groups, but fewer women with PSIS were in relationships (42% vs 57.6% in controls, P = .02). The fertility prognosis in patients with PSIS needs optimization. Patients should be informed about the likelihood of declining gonadotropic function over time.

The individual results of SARS-CoV-2 serological tests measured after the first pandemic wave of 2020 cannot be directly interpreted as a probability of having been infected. Plus, these results are usually returned as a binary or ternary variable, relying on predefined cut-offs. We propose a Bayesian mixture model to estimate individual infection probabilities, based on 81,797 continuous anti-spike IgG tests from Euroimmun collected in France after the first wave. This approach used serological results as a continuous variable, and was therefore not based on diagnostic cut-offs. Cumulative incidence, which is necessary to compute infection probabilities, was estimated according to age and administrative region. In France, we found that a "negative" or a "positive" test, as classified by the manufacturer, could correspond to a probability of infection as high as 61.8% or as low as 67.7%, respectively. "Indeterminate" tests encompassed probabilities of infection ranging from 10.8 to 96.6%. Our model estimated tailored individual probabilities of SARS-CoV-2 infection based on age, region, and serological result. It can be applied in other contexts, if estimates of cumulative incidence are available.

BACKGROUND & AIMS: Despite its high prevalence in the western world metabolic dysfunction-associated steatotic liver disease (MASLD) does not benefit from targeted pharmacological therapy. We measured healthcare utilisation and identified factors associated with high-cost MASLD patients in France. METHODS: The prevalent population with MASLD (including non-alcoholic steatohepatitis) in the CONSTANCES cohort, a nationally representative sample of 200,000 adults aged between 18 and 69, was linked to the French centralised national claims database (SNDS). Study participants were identified by the fatty liver index (FLI) over the period 2015-2019. MASLD individuals were classified according as "high-cost" (above 90th percentile) or "non-high cost" (below 90th percentile). Factors significantly associated with high costs were identified using a multivariate logistic regression model. RESULTS: A total of 14,437 predominantly male (69%) participants with an average age of 53 ± SD 12 years were included. They mainly belonged to socially deprived population groups with co-morbidities such as diabetes, high blood pressure, mental health disorders and cardiovascular complications. The average expenditure was 1860 ± SD 4634 per year. High-cost MASLD cost 10,863 ± SD 10,859 per year. Conditions associated with high-cost were mental health disorders OR 1.79 (1.44-2.22), cardiovascular diseases OR 1.54 (1.21-1.95), metabolic comorbidities OR 1.50 (1.25-1.81), and respiratory disease OR 1.50 (1.11-2.00). The 10% high-cost participants accounted for 58% of the total national health care expenditures for MASLD. CONCLUSION: Our results emphasize the need for comprehensive management of the comorbid conditions which were the major cost drivers of MASLD.
Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common chronic liver disease in European countries, affecting 450% of the European population. Confirmation of diagnosis requires liver biopsy which is an invasive procedure. We studied the healthcare costs of patients with MASLD in order to identify cost predictors and cost drivers. We found that patients cost on average 1860 per year. Conditions associated with high-cost were mental health disorders, cardiovascular diseases, metabolic comorbidities, and respiratory disease.
RESUMO
AIM: To assess the prevalence of severe periodontitis based on the population-based CONSTANCES cohort using a validated self-reported questionnaire. MATERIALS AND METHODS: Individuals were selected from the adult population in France using a random sampling scheme. Analyses were restricted to those invited in 2013-2014 who completed the periodontal health questionnaire at the 2017 follow-up. The risk of severe periodontitis was assessed using the periodontal screening score (PESS) and weighting coefficients were applied to provide representative results in the general French population. RESULTS: The study included 19,859 participants (9204 men, mean age: 52.8 ± 12.6 years). Based on a PESS ≥ 5, 7106 participants were at risk of severe periodontitis, corresponding to a weighted prevalence of 31.6% (95% confidence interval: 30.6%-32.7%). This prevalence was higher among participants aged 55 and over, those with lower socio-economic status as well as current smokers, e-cigarette users and heavy drinkers. Among individuals at risk of severe periodontitis, only 18.8% (17.3%-20.4%) thought they had gum disease, although 50.5% (48.6%-52.5%) reported that their last dental visit was less than 6 months. CONCLUSIONS: The present survey indicates that (1) self-reported severe periodontitis is highly prevalent with marked disparities between groups in the general French adult population, and (2) periodontitis could frequently be under-diagnosed given the low awareness.

BACKGROUND: Identifying factors that predict the course of persistent symptoms that occurred during the COVID-19 pandemic is a public health issue. Modifiable factors could be targeted in therapeutic interventions. OBJECTIVE: This prospective study based on the population-based CONSTANCES cohort examined whether the psychological burden associated with incident persistent symptoms (ie, that first occurred from March 2020) would predict having ≥1 persistent symptom 6-10 months later. METHODS: A total of 8424 participants (mean age=54.6 years (SD=12.6), 57.2% women) having ≥1 incident persistent symptom at baseline (ie, between December 2020 and February 2021) were included. The psychological burden associated with these persistent symptoms was assessed with the Somatic Symptom Disorder-B Criteria Scale (SSD-12). The outcome was having ≥1 persistent symptom at follow-up. Adjusted binary logistic regression models examined the association between the SSD-12 score and the outcome. FINDINGS: At follow-up, 1124 participants (13.3%) still had ≥1 persistent symptom. The SSD-12 score at baseline was associated with persistent symptoms at follow-up in both participants with (OR (95% CI) for one IQR increase: 1.42 (1.09 to 1.84)) and without SARS-CoV-2 infection prior to baseline (1.39 (1.25 to 1.55)). Female gender, older age, poorer self-rated health and infection prior to baseline were also associated with persistent symptoms at follow-up. CONCLUSIONS: The psychological burden associated with persistent symptoms at baseline predicted the presence of ≥1 persistent symptom at follow-up regardless of infection prior to baseline. CLINICAL IMPLICATIONS: Intervention studies should test whether reducing the psychological burden associated with persistent symptoms could improve the course of these symptoms.

Objective: To estimate the proportion of the participants of the French national population-based CONSTANCES cohort exceeding the new low-risk drinking guidelines according to sociodemographic and clinical factors. Methods: From 34,470 participants with follow-up data in 2019, among volunteers aged 18-69 years and invited to enroll in the CONSTANCES cohort in 2016 and 2017, weighted prevalence and odds ratios with 95% confidence intervals (CI) exceeding the guidelines using logistic regressions were presented stratified for age, gender, education, occupational grade, employment, income, marital status, pregnancy, work stress, depression, alcohol dependence, binge drinking, cannabis use, smoking status, e-cigarette use, cardiovascular diseases, and cancer. Results: The guidelines were exceeded more by men at 60.2% (95%CI: 59.3%-61.0%) than by women at 36.6% (95%CI: 35.9%-37.4%). Exceeding the guidelines increased with age, socioeconomic status, smoking, vaping, using cannabis, binge drinking, and alcohol dependence. Being depressed was associated with exceeding the guidelines in women. Even though pregnant women were less likely to exceed the guidelines, 7.6% (95%CI: 5.4%-10.6%) were at-risk drinkers. Conclusion: These findings highlight the need to implement effective prevention measures for at-risk alcohol use among the French population.

BACKGROUND & AIMS: Beyond cardiovascular disease protection, the health consequences of very low concentrations of low-density lipoprotein-cholesterol (LDL-C) remain a matter of debate. In primary hypobetalipoproteinemia (HBL), liver steatosis and cirrhosis have occasionally been reported. Here, we aimed to investigate the association between HBL and the risk of hepatic complications (cirrhosis complications and/or primary liver cancer) in the general population. METHODS: A cohort study was conducted in the French population-based cohort CONSTANCES. Participants with primary HBL (LDL-C <5th percentile for age and sex, [HBL]) were compared with those with normal LDL-C concentrations (40th-60th percentile, [Control]). Participants on lipid-lowering therapies were excluded. For hepatic complications, follow-up events were compared by calculating the incidence density ratio (IDR). The same analyses were replicated in the UK Biobank (UKBB) cohort. RESULTS: In the CONSTANCES and UKBB cohorts, 34,653 and 94,666 patients were analyzed, with median ages of 45 and 56 years, mean LDL-C concentrations (HBL vs. control) of 71 vs. 128 mg/dl and 86 vs. 142 mg/dl, and mean follow-up durations of 5.0 and 11.5 years, respectively. The HBL group presented a higher incidence of hepatic complications than the control group: 0.32/ vs. 0.07/1,000 person-years (IDR = 4.50, 95% CI 1.91-10.6) in CONSTANCES, and 0.69/ vs. 0.21/1,000 person-years (IDR = 3.27, 95% CI 2.63-4.06) in the UKBB. This risk proved to be independent of classic risk factors for liver disease (obesity, alcohol consumption, diabetes, viral hepatitis), including in a 5-year landmark analysis excluding early events. Sensitivity analyses based on apoliprotein-B levels (instead of LDL-C levels) or genetically defined HBL showed similar results. CONCLUSIONS: HBL is associated with a markedly increased risk of hepatic complications. HBL must be considered as a substantial independent risk factor for liver diseases which justifies specific prevention and screening. IMPACT AND IMPLICATIONS: Hypobetalipoproteinemia (HBL) is a lipid disorder characterized by permanent, inherited low levels (below the 5th percentile) of low-density lipoprotein-cholesterol. While HBL is associated with a lower risk of cardiovascular events, some studies suggest that it may be associated with a potential risk of hepatic steatosis and hepatic complications. Here, we studied the association between HBL and hepatic complications (defined as cirrhosis complications and/or primary liver cancer) in two populations of several hundred thousand people, both in France (CONSTANCES cohort) and the United Kingdom (UKBB). The results show that HBL is associated with a significant and independent excess risk of hepatic complications, including primary liver cancer. Thus, in people with HBL, the value of regular liver monitoring must be studied.

BACKGROUND: We aimed to assess factors associated with uncontrolled blood pressure (BP) among individuals with hypertension on treatment, by sex. METHODS: We conducted a nested cross-sectional analysis using data from the population-based cohort study CONSTANCES, designed as a randomly selected sample of French adults aged 18-69 years at study inception. We included 11â760 participants previously diagnosed with hypertension and taking antihypertensive medications. Uncontrolled BP was defined as mean systolic BP ≥140 mmHg and/or mean diastolic BP ≥90 mmHg. Sex-specific age-adjusted multivariable analyses were performed using logistic regression models stratified by stages of uncontrolled hypertension. RESULTS: The mean age of participants was 59.4 years. The prevalence of uncontrolled BP was 51.4%, and it was higher in men than in women [adjusted odds ratio (aOR), 1.80; 95% CI, 1.67-1.94]. In both sexes, the lower the age, the lower the prevalence of uncontrolled hypertension. Low level of education and history of cardiovascular events had, respectively, higher and lower odds of uncontrolled BP. In men, additional risk factors included overweight and obesity (aOR, 1.15; 95% CI, 1.00-1.32; and aOR, 1.45; 95% CI, 1.23-1.70, respectively), lack of physical activity (aOR, 1.20; 95% CI, 1.04-1.40), low adherence to a Dietary Approach to Stop Hypertension diet (aOR, 1.21; 95% CI, 1.05-1.40) and heavy alcohol consumption (aOR, 1.33; 95% CI, 1.08-1.63), with the last two factors persisting across different stages of uncontrolled BP. CONCLUSIONS: From a population-based perspective, socio-economic and behavioural characteristics were risk factors for uncontrolled hypertension, but they differed by sex and by stage of uncontrolled hypertension. Modifiable risk factors, such as weight, diet, physical activity and alcohol consumption, have an important role in the control of hypertension.

OBJECTIVES: The impact of chronic occupational exposures to irritants on asthma remains discussed. We studied the associations between occupational exposures and asthma, with specific interest for chronic exposure to irritants, including disinfectants and cleaning products (DCPs) and solvents. METHODS: Cross-sectional analyses included 115 540 adults (55% women, mean age 43 years, 10% current asthma) working at inclusion in the French population-based CONSTANCES cohort (2012-2020). Current asthma was defined by ever asthma with symptoms, medication or asthma attacks (past 12 months), and the asthma symptom score by the sum of 5 respiratory symptoms (past 12 months). Both lifetime and current occupational exposures were assessed by the Occupational Asthma-specific Job-Exposure Matrix. Associations were evaluated by gender using logistic and binomial negative regressions adjusted for age, smoking status and body mass index. RESULTS: In women, associations were observed between current asthma and lifetime exposure to irritants (OR 1.05, 95% CI 1.00 to 1.11), DCPs (1.06, 95% CI 1.00 to 1.12) and solvents (1.06, 95% CI 0.98 to 1.14). In men, only lifetime exposure to DCPs (1.10, 95% CI 1.01 to 1.20) was associated with current asthma. Lifetime exposure to irritants was associated with higher asthma symptom score both in women (mean score ratio: 1.08, 95% CI 1.05 to 1.11) and men (1.11, 95% CI 1.07 to 1.15), especially for DCPs (women: 1.09, 95% CI 1.06 to 1.13, men: 1.21, 95% CI 1.15 to 1.27) and solvents (women 1.14, 95% CI 1.10 to 1.19, men: 1.10, 95% CI 1.05 to 1.15). For current exposures, no consistent associations were observed with current asthma and asthma symptom score. CONCLUSIONS: Lifetime occupational exposures to irritants were associated with current asthma and higher asthma symptom score. These exposures should be carefully considered in asthma management.

This study aims to estimate the prevalence of tobacco use in 2017 and 2019 in the French population covered by the Régime Général d'Assurance Maladie according to employment status. From the French national CONSTANCES cohort, 18,008 randomly recruited volunteers aged between 18 and 69 years, affiliated to the Régime Général d'Assurance Maladie and enrolled in 2017, were included in the analysis. The prevalence of tobacco use according to employment status was estimated. Estimates of these prevalence data were calculated in 2017 and 2019 after correction for selection bias at inclusion and non-response at follow-up. In 2019, smoking prevalence was higher among unemployed people (29.2% among men and 20.7% among women) than among employed people (16.5% among men and 13.8% among women). Smoking prevalence was highest among those not in work for health reasons (38.5% among men and 35.8% among women). Smokers were more likely to be unemployed than non-smokers (OR 2.63 [95% confidence interval (CI): 1.79; 3.85] in men and OR 1.55 [95% CI: 1.08; 2.22] in women). Among men, the prevalence of employed people among light smokers (<10 cigarettes/day) significantly decreased between 2017 (87.1%) and 2019 (74.8%). These results underline the importance of reinforcing smoking prevention campaigns among the unemployed, particularly for health reasons.
Estimer les prévalences d'usage de tabac en 2017 et en 2019 en population française couverte par le Régime Général d'Assurance Maladie en fonction du statut vis-à-vis de l'emploi. À partir d'un échantillon de 18 008 volontaires inclus en 2017 dans CONSTANCES, une cohorte nationale en population générale française ayant recruté de manière aléatoire des volontaires de 18-69 ans affiliés au Régime Général d'Assurance Maladie, les prévalences d'usage du tabac en fonction de du statut vis-à-vis de l'emploi ont été estimées en 2017 et en 2019 après correction pour les biais de sélection à l'inclusion et de non-réponse au suivi. En 2019, la prévalence du tabagisme était plus élevée chez les actifs inoccupés (29,2 % chez les hommes et 20,7 % chez les femmes) par rapport aux actifs occupés (16,5 % chez les hommes et 13,8 % chez les femmes). La prévalence du tabagisme la plus élevée concernait les personnes sans activité professionnelle pour raisons de santé (38,5 % chez les hommes et 35,8 % chez les femmes). Les fumeurs étaient plus à risque d'être actifs inoccupés comparativement aux non-fumeurs (OR 2,63 [95 % Intervalle de confiance [IC] : 1,79 ; 3,85] chez les hommes et OR 1,55 [95 % IC : 1,08 ; 2,22] chez les femmes). Chez les hommes, la prévalence d'actifs occupés parmi les petits fumeurs (<10 cigarettes/jour) a baissé entre 2017 (87,1 %) et 2019 (74,8 %). Ces analyses soulignent l'importance d'intensifier les campagnes de prévention sur le tabagisme parmi les actifs inoccupés et les inactifs, en particulier pour raisons de santé.
