Main Causal Agents of Occupational Asthma in France, Reported to the National Network for Occupational Disease Vigilance and Prevention (RNV3P) 2001-2018.

OBJECTIVES: The definition of work-related Asthma (WRA) has changed in recent years and new etiologies and agents have been identified. The aim of this study is to describe the main causal agents of WRA in France in the period 2001-2018 in the main work sectors. METHODS: Data were collected from the French national network of occupational health surveillance and prevention [Réseau National de Vigilance et de Prévention des Pathologies Professionnelles (RNV3P)], Data between 2001 and 2018 with at least a probable or certain association with one occupational agent, were included. RESULTS: Work sectors with more cases OF WRA included personal service activities (10.6%), food industry (10.2%) and healthcare activities (7.6%). WRA cases were most frequently related to flour (10%), quaternary ammoniums compounds (5.3%), isocyanates (5.1%) and cleaning products (4.8%). CONCLUSION: Occupational exposure to specific agents capable of causing WRA is still present, and four agents represent more than 25% of the cases. Actions to prevent respiratory exposure are still relevant.

[Obesity and high blood pressure in French West Indies women, some difference according to definition of obesity; BMI or abdominal obesity]. / Obésité et hypertension artérielle chez la femme antillaise, la prévalence diffère selon la définition utilisée, indice de masse corporelle ou tour de taille.

OBJECTIVES: To compare prevalence of abdominal obesity with obesity defined as BMI >or=30 kg/m2 in a West Indies population, and to define the relation between obesity and hypertension. METHODS: A cross-sectional study of 2420 consecutive unemployed subjects referred for check-up in the two health centres of Guadeloupe, a French Caribbean island. Height and weight were measured and the body mass index (BMI) was calculated as weight/height2 (kg/m2). Obesity was defined as BMI >or=30 kg/m2 and excess weight as BMI >or=25 kg/m2 and<30 kg/m2. Abdominal obesity was defined as waist measurement more than 88 cm for women and more than 102 cm for men. RESULTS: [table: see text] CONCLUSION: A high prevalence of obesity was observed in this Caribbean population suggesting the interest of primary prevention in The Caribbean. In women, abdominal obesity (waist measurement>88 cm) was more frequent than obesity defined as BMI>30 kg/m2). In a multivariate analysis, obesity is an independent risk factor of hypertension (Odds-ratio=3), however the definition of obesity.

[Prevalence of hypertension in a disadvantaged population in Antilles: a major role for obesity?]. / Prévalence de l'HTA en population précaire aux Antilles : rôle majeur de l'obésité?

UNLABELLED: The aim of this study was to evaluate the prevalence of hypertension and its management in a disadvantaged population, essentially composed of those receiving state subsidies and the unemployed. METHODS: The PHAPPG study : Prevalence of Hypertension in a Population Précaire Guadeloupéenne (disadvantaged population in Guadeloupe) included 2420 consecutive people considered to be 'disadvantaged' seen in the two medical examination centres in Guadeloupe between November 2001 and November 2003. RESULTS: The prevalence of obesity was considerable throughout the female population of Antilles (29%). It was recorded in 12% of men. The prevalence of hypertension in the population was 24.7% for men and 22.1% for women. Obesity was the main factor that could explain the higher prevalence of hypertension noted in Antilles, especially among 'disadvantaged' women. In effect, after correction for other risk factors and for age, this prevalence of hypertension was on average three times higher amongst the obese compared to subjects with normal weights. CONCLUSION: The prevalence of hypertension is elevated in the population of Antilles, especially among the disadvantaged. Obesity is the key factor, upon which a primary prevention policy for hypertension could be based.

Reducing the burden of arterial hypertension: what can be expected from an improved access to health care? Results from a study in 2420 unemployed subjects in the Caribbean.

High prevalence and poor control of hypertension have been observed in populations with low-socioeconomic status. Comparing an unemployed population with another employed population sharing the same culture, and another employed population living in another environment might enlighten the effects of factors accessible to primary prevention on the one hand and access to health care on the other hand. The objectives are, first, to describe blood pressure (BP) prevalence and control in an unemployed Caribbean population benefiting from State financial support and good access to health care and second, compare the results in this population with those observed, with the same methodology in two employed populations, one in the Caribbean and one in metropolitan France. A cross-sectional study of 2420 consecutive unemployed subjects referred for check-up in the two health centres of Guadeloupe, a French Caribbean island. Hypertension prevalence was 25.2% in men and 22.1% in women. BP was controlled in 17.3% of men and 37.2% of women receiving antihypertensive medication. Among women, 58% were overweight and 29% obese. Prevalence of hypertension was higher among the unemployed and employed Caribbean population, than among an employed metropolitan French population. A high prevalence of obesity was observed in the two Caribbean populations suggesting the interest of primary prevention in the Caribbean. Burden of hypertension in a population relates to the development of hypertension (primary prevention) and control of hypertension (secondary prevention). Identifying hypertensive patients and controlling blood pressure are both important to reduce the disease burden.

[Access to care: not enough to completely abolish the disparity in hypertension management at the socio-economic level]. / Une bonne couverture sociale et un bon accès aux soins: un prérequis nécessaire mais insuffisant pour faire disparaître une disparité de prise en charge de l'HTA selon le niveau socio-économique.

Higher prevalence and poorer control of hypertension have been observed in populations with low socioeconomic status. The causal link between socioeconomic factors and hypertension is complex. What is the impact of medical services compared with other health status determinants? We aimed to assess blood pressure prevalence and control in an unemployed disadvantaged population receiving state financial support and with easy access to health care. This was a cross-sectional study of 2420 consecutive subjects in Guadeloupe, a French Caribbean island, who were referred for check-up in a health centre. As unemployed persons, they all benefited from state financial support and special coverage. Blood pressure was averaged from three consecutive measurements. Subjects not taking antihypertensive medications and with average BP > 140/90 mmHg underwent an additional visit. A total of 1088 men aged 42 +/- 10.6 years and 1332 women aged 40 +/- 11 years were included from November 2001 to November 2003. Hypertension prevalence was 25.2% in men and 22.1% in women, while awareness was 40.2% in men and 73% in women. Blood pressure was controlled (<140/90 mmHg) in 19% of men and 37,2 % of women receiving antihypertensive medication. Among women, 58% were overweight and 29% obese. Hypertension prevalence was slightly higher than that recently observed in cohorts of workers in Caribbean regions and metropolitan France. Control was poorer despite similar awareness and treatment rates. These findings suggest that a universal healthcare system can reduce, but not fully eliminate, disparities in hypertension care and prevalence across income categories.

[Arterial hypertension in the French Caribbean regions: gender related differences]. / Hypertension artérielle aux Antilles: différences liées au sexe.

BACKGROUND: Arterial hypertension is a frequent disease, responsible for a significant morbidity, in the French Caribbean regions. Today, epidemiological studies on this topic remain few. OBJECTIVES: To analyse the prevalence, awareness, treatment and control of arterial hypertension in the French Caribbean regions. METHODS: Analysis of the INHAPAG cohort (Incidence of Arterial Hypertension in the Working population Antillo-Guyanaise) carried out in 2001, and including 6113 active subjects recruited in Guadeloupe, Martinique and Guyana. The procedure of diagnosis of arterial hypertension comprises two visits, with a series of three measurements of the blood pressure at each visit. RESULTS: Prevalence of hypertension is estimated to be 18.9% among women and 19.5% among men. The rates of treatment are higher among women (74.8 vs 34.4%) than among men, resulting in a much better control rate (61.3% vs 38.6% among men). An analysis of factors associated with the presence of arterial hypertension shows a noxious role of low education level among women. CONCLUSION: Our study finds marked differences between women and men in the treatment and control of arterial hypertension and underline the need for improving blood pressure management of the latter.

Job constraints and arterial hypertension: different effects in men and women: the IHPAF II case control study.

AIMS: To examine, in a working population of men and women, the relation between organisational job constraints (job strain, passive and active jobs) and incident hypertension and the buffering effect of social support at work on this relation. METHODS: A nested case control study was designed within the IHPAF (Incidence of Hypertension in a French Working Population) cohort study. The 20 worksite physicians participating in the study enrolled 203 cases and matched each case for age (SD 10 years) and sex with two normotensive subjects attending the follow up screening immediately after him or her. As a result, 426 men and 183 women were included in the study. RESULTS: Mean age was 41.8 (SD 7.8) years in men and 43.5 (SD 7.5) years in women. Relations between job constraints and hypertension were stronger in women than in men. Odds ratios (OR) were 3.20 (95% CI 0.92 to 11.12) in women and 2.60 (95% CI 1.15 to 5.85) in men for job strain, 4.73 (95% CI 1.36 to 16.42) in women and 2.30 (95% CI 1.01 to 5.26) in men for passive jobs, and 4.51 (95% CI 1.24 to 16.43) in women and 2.39 (95% CI 1.10 to 5.18) in men for active jobs. Low social support at work was not related to hypertension and did not decrease the association with organisational risk factors. In both hypertensive men and women, obesity was related to hypertension (OR = 13.20 (95% CI 3.34 to 52.14) in women and 6.54 (95% CI 2.99 to 14.29) in men) and the prevalence of recent stressful life events was significantly lower in hypertensive women (OR = 0.32 (95% CI 0.12 to 0.89)) and men (OR = 0.37 (95% CI 0.20 to 0.67) compared with normotensives. Alcohol consumption was a significant risk factor for hypertension in women (OR = 3.47 (95% CI 1.18 to 10.25)). CONCLUSION: A stronger relation between job constraints and hypertension was observed in women compared with men. These findings emphasise the need of addressing more sex-specific concepts of work related stress on the one hand, and of understanding the direct and indirect mechanisms linking psychosocial factors and hypertension in both sexes on the other hand.

One-year hypertension incidence and its predictors in a working population: the IHPAF study.

THE AIMS OF OUR STUDY WERE: (i). to estimate the yearly incidence rates based on one vs two visits in a working population and (ii). to identify incident hypertension modifiable risk factors. A total of 21566 normotensive subjects were included in a 1-year cohort study. Blood pressure (BP) levels at inclusion and at the second year screening were measured on the basis of two visits, that is, if BP was over 140/90 mmHg in untreated subjects, they were invited to a control visit 1 month later. Height and weight were measured and behavioural risk factors were collected. Among the 17465 subjects who completed the entire protocol (9691 men and 7774 women), 17026 remained normotensive at a 1-year interval and 439 (325 men and 114 women) became hypertensive. Crude yearly incidence rates based on one visit were 6.21% in men and 3.06% in women, compared with 3.04% in men and 1.34% in women when incidence rates were based on two visits, a more than twofold difference. Age and body mass index at baseline were the two major independent determinants of incident hypertension in both genders. Smoking and alcohol consumption were significant risk factors in men but not in women, and a low educational level only in women. BP measurement on separate occasions is necessary to avoid overestimation of incidence. Weight in both genders and alcohol consumption in men were the main modifiable predictors of hypertension.
