Background: The work ability index (WAI) is a frequently used tool in occupational health to identify workers at risk for a reduced work performance and for work-related disability. However, information about the prognostic value of the WAI to identify workers at risk for sickness absence is scarce. Objectives: To investigate the prognostic value of the WAI for sickness absence, and whether the discriminative ability differs across demographic subgroups. Methods: At baseline, the WAI (score 7-49) was assessed among 1,331 office workers from a Dutch financial service company. Sickness absence was registered during 12-months follow-up and categorised as 0 days, 0

Background: Guidelines on home blood pressure measurement (HBPM) recommend taking at least 12 measurements. For screening purposes, however, it is preferred to reduce this number. We therefore derived and validated cut-off values to determine hypertension status after the first duplicate reading of a HBPM series in a web-based worksite health promotion programme. Method: Nine hundred forty-five employees were included in the derivation and 528 in the validation cohort, which was divided into a normal (n = 297) and increased cardiometabolic risk subgroup (n = 231), and a subgroup with a history of hypertension (n = 98). Six duplicate home measurements were collected during three consecutive days. Systolic and diastolic readings at the first duplicate measurement were used as predictors for hypertension in a multivariate logistic model. Cut-off values were determined using receiver operating characteristics analysis. Results: Upper (≥150 or ≥95 mmHg) and lower limit (<135 and <80 mmHg) cut-off values were derived to confirm or reject presence of hypertension after one duplicate reading. The area under the curve was 0.94 (standard error 0.01, 95% confidence interval 0.93–0.95). In 62.5% of participants, hypertension status was determined, with 1.1% false positive and 4.7% false negatives. Performance was similar in participants with high and low cardiometabolic risk, but worse in participants with a history of hypertension (10.4% false negatives). Conclusion: One duplicate home reading is sufficient to accurately assess hypertension status in 62.5% of participants, leaving 37.5% in which the whole HBPM series needs to be completed. HBPM can thus be reliably used as screening tool for hypertension in a working population. [ABSTRACT FROM AUTHOR]

Background: Primary prevention programs at the worksite can improve employee health and reduce the burden of cardiovascular disease. Programs that include a web-based health risk assessment (HRA) with tailored feedback hold the advantage of simultaneously increasing awareness of risk and enhancing initiation of health-behaviour change. In this study we evaluated initial health-behaviour change among employees who voluntarily participated in such a HRA program. Methods: We conducted a questionnaire survey among 2289 employees who voluntarily participated in a HRA program at seven Dutch worksites between 2007 and 2009. The HRA included a web-based questionnaire, biometric measurements, laboratory evaluation, and tailored feedback. The survey questionnaire assessed initial self-reported health-behaviour change and satisfaction with the web-based HRA, and was e-mailed four weeks after employees completed the HRA. Results: Response was received from 638 (28%) employees. Of all, 86% rated the program as positive, 74% recommended it to others, and 58% reported to have initiated overall health-behaviour change. Compared with employees at low CVD risk, those at high risk more often reported to have increased physical activity (OR 3.36, 95% CI 1.52-7.45). Obese employees more frequently reported to have increased physical activity (OR 3.35, 95% CI 1.72-6.54) and improved diet (OR 3.38, 95% CI 1.50-7.60). Being satisfied with the HRA program in general was associated with more frequent self-reported initiation of overall health-behaviour change (OR 2.77, 95% CI 1.73-4.44), increased physical activity (OR 1.89, 95% CI 1.06-3.39), and improved diet (OR 2.89, 95% CI 1.61-5.17). Conclusions: More than half of the employees who voluntarily participated in a web-based HRA with tailored feedback, reported to have initiated health-behaviour change. Self-reported initiation of health-behaviour change was more frequent among those at high CVD risk and BMI levels. In general employees reported to be satisfied with the HRA, which was also positively associated with initiation of health-behaviour change. These findings indicate that among voluntary participating employees a web-based HRA with tailored feedback may motivate those in greatest need of health-behaviour change and may be a valuable component of workplace health promotion programs.

Background: European guidelines on primary prevention of cardiovascular disease (CVD) recommend the SCORE risk charts for determining CVD risk, which include blood pressure and serum cholesterol as risk parameters. To facilitate cost-effective large-scale screening, we aimed to construct a risk score with 'non-invasive' parameters as a first screening step to identify persons at increased CVD risk requiring further risk assessment.Methods: We used data of Dutch employees from 25 organisations participating in a health risk assessment between August 2007 and January 2013. Backward multivariate logistic regression analysis was employed to select non-invasive, independent predictors of high CVD risk, defined as the 10-year risk of fatal CVD of ≥5 % based on the SCORE formula. The total CVD risk score was calculated as the summed coefficients of the retained variables.Results: Data of 6189 male participants was used for the development and validation of the risk score. Age, tobacco use, history of hypertension, alcohol consumption, BMI, and waist circumference were independent predictors of high CVD risk. Ten-fold cross-validation resulted in an area under the curve of 0.95 (SE 0.01, 95 % confidence interval 0.94-0.96). A cut-off score ≥45 on the CVD risk score yielded a sensitivity of 0.93, and a specificity of 0.85.Conclusions: We developed a simple, non-invasive risk score that accurately identifies persons at increased CVD risk according to the SCORE formula in a population of working men. The risk score enables a stepwise approach in large screening programmes, strongly reducing the number of persons that require full risk estimation including blood pressure and cholesterol measures.
