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.

Prevalence and therapeutic control of hypertension in 30,000 subjects in the workplace.

-To assess blood pressure (BP) control in a French working population through the use of a careful assessment of BP based on 2 different visits in 1 month, 17 359 men and 12 267 women were evaluated from January 1997 to April 1998. The initial phase was a cross-sectional analysis of a cohort study designed to assess the incidence of arterial hypertension in a French working population. Information was collected by the work-site physician during the annual examination. BP was measured with a validated automatic device. Among subjects with BP >/= mm Hg, patients not treated with antihypertensive drugs were invited to have an additional BP measurement taken 1 month later. The prevalence of hypertension (BP >/= mm Hg) based on 2 visits was 16.2% in men and 9.4% in women. When the diagnosis of hypertension was based on 2 visits, its prevalence was 41% lower in men and 36% lower in women compared with that of a diagnosis based on a single visit. Accordingly, the awareness of hypertension was 49% higher in men and 40% higher in women. Overall, 12.5% of hypertensive men and 33.2% of hypertensive women taking antihypertensive medication had their BP levels lowered to < mm Hg by treatment. Although the percentage of hypertensive men and women under current treatment who were aware of their hypertension increased with age, BP control among treated subjects decreased with age. Ineffective BP control with treatment accounted for 33% of BP levels >/= mm Hg in men and 40% of those observed in women. In this large French working population, estimates of hypertension therapeutic control depend heavily on the number of BP measurements. Despite these methodological precautions, insufficient awareness of BP and insufficient BP control through treatment remain 2 major public health problems.

[Cause of non-pertinent hospital stays: interobserver concordance using the French version of the Appropriateness Evaluation Protocol]. / Etude de la concordance inter-observateurs des raisons de non-pertinence des journées d'hospitalisation identifiée par la version française de l'Appropriateness Evaluation Protocol (2e partie).

BACKGROUND: The modified French version of the Appropriateness Evaluation Protocol (AEPf) has been validated. Inappropriate days according to simple medical and technical criteria are identified with this tool. The aim of this study is to highlight the interest of investigating the reasons for inappropriate days and to assess the inter-observers reliability of the questionnaire developed for this purpose. METHODS: This questionnaire collects on one hand the needs of patients - distinguishing health care and accommodation needs - and on the other hand the reasons for inappropriate hospital days. The data were collected from January to September 1998 in nine voluntary medical and surgical departments. For each day of study randomly selected, each inappropriate hospital day according to AEPf has been included. Data were collected by two health professionals (a nurse and a physician), using a concurrent design. RESULTS: The reliability of the over-ride option of the appropriateness assessment of the 345 hospital days was good (overall Kappa coefficient: 0.66; 95% CI: 0.55-0.78). The comparison of the two expert judgments on health care needs fulfilled during the hospital day was acceptable; the Kappa coefficient was 0.62 (95% CI: 0.52-0.72). The reliability of expert assessment on patient accommodation needs (home, housing facilities or hospital) was good (Kappa coefficient: 0.67; 95% CI: 0.60-0.75). When hospital was not the accommodation the most adapted for patient, the reliability of the reasons for inappropriate days was high (Kappa coefficient: 0.75; 95% CI: 0.61-0.80). Kappa coefficients were different between hospitals, indicating a center effect. CONCLUSION: This instrument has been found to be reliable and should be used in complement of the first part of the AEPf which assess the prevalence of inappropriate days. It might help to detect dysfunctions within or outside the hospital and thus be used for evaluation or planning of health care.
