Objectives Individuals with reduced nocturnal blood pressure (BP) dipping are at increased risk of cardiovascular disease compared to persons with normal BP dipping. Although the relation of work-related factors and BP has been studied extensively, very little is known of the association between work-related factors and 24-h BP patterns in aging workers. We examined the cross-sectional relation of work-related risk factors, including occupational status, work-time mode, job demands and job control, with ambulatory BP in aging workers, focusing on nocturnal BP dipping. Methods 208 workers (mean age 62 ± 3 years; 75% women) from two Finnish population-based cohort studies underwent 24-h ambulatory BP monitoring. Work-related factors were inquired using a questionnaire. Nocturnal BP dipping was calculated as [1 − (asleep BP/awake BP)] × 100. Results Shift workers demonstrated a higher nocturnal diastolic BP dipping than regular day workers (19% vs. 17%, p = 0.03) and had a significantly higher systolic awake BP than regular day workers (136.5 mmHg vs. 132.5 mmHg, p = 0.03). Participants with high job demands demonstrated a smaller nocturnal systolic BP dipping than participants with low job demands (14% vs. 16%, p = 0.04). We did not observe significant differences in nocturnal systolic or diastolic BP dipping between groups categorized by occupational status or job control. Conclusions Although shift workers have a higher daytime BP than regular daytime workers, they exhibit greater nighttime BP dipping. Participants with high job demand had smaller nighttime BP dipping than participants with low job demand. Job control or occupation did not affect the 24-h ambulatory BP profile of aging workers.

Objectives:Retirement is a major life event characterized by removal of work-related stressors and changes in health behaviours. The association between retirement and changes in blood pressure (BP), and particularly in ambulatory BP, has been scarcely studied. We aimed to examine changes in ambulatory BP during retirement transition.Methods:Two hundred and fifty ageing workers (mean age 63.2 years, 84% women) from the Finnish Retirement and Aging study participated in annual office BP measurements and 114 (mean age 63.1, 90% women) of them underwent annual ambulatory BP measurements before and after retirement. On average, the participants provided data on ambulatory BP at 2.7 (range 2–4) measurements. We used generalized linear models to examine BP changes at retirement.Results:Most marked changes in BP during the follow-up were observed for asleep SBP, which decreased before retirement, increased during retirement transition and plateaued after retirement (before retirement vs. retirement transition P = 0.07 and after retirement vs. retirement transition P = 0.02). Awake SBP and 24-h SBP declined with most apparent decrease before retirement (before retirement vs. retirement transition P = 0.07 and P = 0.07). Awake DBP and 24-h DBP showed relatively consistent decline throughout the follow-up with no differences between the time periods. SBP and DBP dipping reduced before and during retirement transition, but not after retirement. Among shift workers, asleep BP increased and BP dipping decreased more than in regular day workers.Conclusion:Retirement was found to associate with beneficial changes in awake BP but unfavourable changes in asleep BP, especially in shift workers.

Cardiovascular Disease (CVD) is a leading cause of mortality worldwide. Conventional risk factors, e.g., smoking, hypercholesterolemia and high blood pressure has been shown to partially explain the increased risk [1]. However, other CVD risk factors have also been identified, including exposure to stressors in private life or at work, such as stressful events and job strain [2]. Chronic stress resulting from occupational stressors has been associated with higher blood pressure in some studies, but the association between other life stressors and blood pressure is more complicated [3,4].The exact mechanisms through which mental strain and stress increase CVD risk remain obscure [5]. Increased arterial stiffness, most commonly measured using carotid-femoral Pulse Wave Velocity (PWV), is a strong predictor of future CVD events [6]. A few studies have examined the association of stressful life events, life stress and job strain with arterial stiffness [7-13]. However,

Objective: Retirement is a major life event characterized by removal of work-related stressors and changes in health behaviours. The association between retirement and changes in blood pressure (BP), and particularly in ambulatory BP, has been scarcely studied. We aimed to examine changes in ambulatory BP during retirement transition. Design and method: Two hundred and fifty ageing workers (mean age 63.2 years, 84% women) from the Finnish Retirement and Aging study participated in annual office BP measurements and 114 (mean age 63.1, 90% women) of them underwent annual ambulatory BP measurements before and after retirement. On average, the participants provided data on ambulatory BP at 2.7 (range 2 - 4) measurements. We used generalized linear models to examine BP changes at retirement. The FIREA study was conducted in accordance with the Helsinki declaration and was approved by the Ethics Committee of Hospital District of Southwest Finland (ETMK: 84/1801/2014). All participants gave written informed consent. Results: Most marked changes in BP during the follow-up were observed for asleep SBP, which decreased before retirement, increased during retirement transition and plateaued after retirement (before retirement vs. retirement transition P = 0.07 and after retirement vs. retirement transition P = 0.02). Awake SBP and 24-h SBP declined with most apparent decrease before retirement (before retirement vs. retirement transition P = 0.07 and P = 0.07). Awake DBP and 24-h DBP showed relatively consistent decline throughout the follow-up with no differences between the time periods. SBP and DBP dipping reduced before and during retirement transition, but not after retirement. Among shift workers, asleep BP increased and BP dipping decreased more than in regular day workers. Conclusions: Retirement was found to associate with beneficial changes in awake BP but unfavourable changes in asleep BP, especially in shift workers.
