Influence of lifestyle factors on long-term sickness absence among female healthcare workers: a prospective cohort study

The importance of a healthy lifestyle despite chronic pain: Prospective cohort with 11-year register follow-up

The purpose of the study was to investigate to which extent a healthy lifestyle in female healthcare workers with chronic pain contributes to reducing the risk of disability pension. We conducted a prospective cohort study with an 11-year registry follow-up. Overall, 2386 Danish female healthcare workers with chronic pain completed a questionnaire about work and lifestyle (leisure-time physical activity, smoking, and body mass index (BMI)). Data on disability benefit payments were obtained from the Danish Register for Evaluation of Marginalization. Two models (minimally and fully adjusted for different potential confounders) were tested using the Cox proportional hazards model. During the follow-up period, 17.9% of the healthcare workers obtained disability pension. Low levels of leisure time physical activity (reference: moderate level) increased the risk of disability pension in the minimally (Hazard Ratio: 1.38 (95% CI: 1.14-1.69)) and fully adjusted models (Hazard Ratio: 1.27 (95% CI: 1.04-1.56)). Being highly physically active, as opposed to being moderately active, did not confer additional protection. Additionally, a positive association was observed between smoking and disability pension in the minimally adjusted model (Hazard Ratio: 1.27 (95% CI: 1.05-1.54)). BMI was not an influential factor. In female healthcare workers with chronic pain, at least moderate levels of physical activity is a protective factor for disability pension. Effective promotion strategies should be designed for both workplace and non-workplace settings.

Latent classes of unhealthy behaviours and their associations with subsequent sickness absence: a prospective register-linkage study among Finnish young and early midlife employees

OBJECTIVES

Unhealthy behaviours are associated with increased sickness absence (SA), but few studies have considered person-oriented approach in these associations. Using latent class analysis, we examined clustering of unhealthy behaviours among Finnish municipal employees and their associations with subsequent SA.

DESIGN

A prospective register-linkage study.

SETTING

Unhealthy behaviours (low leisure-time physical activity, non-daily fruit and vegetable consumption, insufficient sleep, excessive alcohol use and tobacco use) were derived from the Helsinki Health Study questionnaire survey, collected in 2017 among 19- to 39-year-old employees of the City of Helsinki, Finland.

PARTICIPANTS

A total of 4002 employees (81% women) of the City of Helsinki, Finland.

PRIMARY OUTCOME MEASURES

The questionnaire data were prospectively linked to employer's SA register through March 2020. Associations between latent classes of unhealthy behaviours and subsequent SA (1-7 days/8+ days/all lengths) were examined using negative binomial regression.

RESULTS

Among women, a three-class latent class model was selected: (1) few unhealthy behaviours (84%), (2) excessive alcohol and tobacco use (12%) and (3) several unhealthy behaviours (5%). Women belonging to classes 2 and 3 had increased SA rates compared with those in class 1, regardless of the length of SA spells. Among men, a 2-latent class model was selected: (1) few unhealthy behaviours (53%) and (2) several unhealthy behaviours (47%). Men belonging to class 2 had increased rates of 1-7 days' SA compared with men in class 1.

CONCLUSIONS

This study suggests that preventive actions aiming to reduce employees' SA should consider simultaneously several unhealthy behaviours. Targeted interventions may benefit of identifying the clustering of these behaviours among occupational groups.

Effectiveness of eHealth Interventions Targeting Employee Health Behaviors: Systematic Review

BACKGROUND

The number of people with noncommunicable diseases is increasing. Noncommunicable diseases are the major cause of disability and premature mortality worldwide, associated with negative workplace outcomes such as sickness absence and reduced work productivity. There is a need to identify scalable interventions and their active components to relieve disease and treatment burden and facilitate work participation. eHealth interventions have shown potential in clinical and general populations to increase well-being and physical activity and could be well suited for workplace settings.

OBJECTIVE

We aimed to provide an overview of the effectiveness of eHealth interventions at the workplace targeting employee health behaviors and map behavior change techniques (BCTs) used in these interventions.

METHODS

A systematic literature search was performed in PubMed, Embase, PsycINFO, Cochrane CENTRAL, and CINAHL in September 2020 and updated in September 2021. Extracted data included participant characteristics, setting, eHealth intervention type, mode of delivery, reported outcomes, effect sizes, and attrition rates. Quality and risk of bias of the included studies were assessed using the Cochrane Collaboration risk-of-bias 2 tool. BCTs were mapped in accordance with the BCT Taxonomy v1. The review was reported according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) checklist.

RESULTS

In total, 17 randomized controlled trials met the inclusion criteria. The measured outcomes, treatment and follow-up periods, content of eHealth interventions, and workplace contexts had high heterogeneity. Of the 17 studies, 4 (24%) reported unequivocally significant findings for all primary outcomes, with effect sizes ranging from small to large. Furthermore, 53% (9/17) of the studies reported mixed results, and 24% (4/17) reported nonsignificant results. The most frequently targeted behavior was physical activity (15/17, 88% of the studies); the least frequently targeted behavior was smoking (2/17, 12% of the studies). Attrition varied greatly across the studies (0%-37%). Risk of bias was high in 65% (11/17) of the studies, with some concerns in the remaining 35% (6/17). Interventions used various BCTs, and the most frequently used were feedback and monitoring (14/17, 82%), goals and planning (10/17, 59%), antecedents (10/17, 59%), and social support (7/17, 41%).

CONCLUSIONS

This review suggests that, although eHealth interventions may have potential, there are still unanswered questions regarding their effectiveness and what drives the mechanism behind these effects. Low methodological quality, high heterogeneity and complexity, the characteristics of the included samples, and often high attrition rates challenge the investigation of the effectiveness and the making of sound inferences about the effect sizes and significance of the results. To address this, new studies and methods are needed. A megastudy design in which different interventions are evaluated in the same population over the same period on the same outcomes may solve some of the challenges.

Can a Healthy Lifestyle Prevent Disability Pension among Female Healthcare Workers with Good and Poor Self-Rated Health? Prospective Cohort Study with 11-Year Register Follow-Up

BACKGROUND

Our purpose was to investigate whether healthy lifestyle habits prevent disability pension among female healthcare workers.

METHODS

We conducted a prospective cohort study with an 11-year register follow-up in which 8159 female healthcare workers from Denmark completed a questionnaire concerning self-rated health, work environment, leisure-time physical activity (LTPA), smoking, and body mass index (BMI). Data on disability benefit payments were obtained from the Danish Register for Evaluation of Marginalization during an 11-year follow-up. Potential confounders included age, occupational education, psychosocial work factors, and physical exertion during work.

RESULTS

Among workers in good health at baseline, smoking, obesity, and low levels of LTPA were risk factors for disability pension during 11-year follow-up. Among workers with poor health, only low levels of physical activity were a risk factor for disability pension.

CONCLUSIONS

This underscores the importance of a healthy lifestyle, specially being physically active, for preventing premature exit from the labor market in female healthcare workers.

Enhancing the health of NHS staff: eTHOS - protocol for a randomised controlled pilot trial of an employee health screening clinic for NHS staff to reduce absenteeism and presenteeism, compared with usual care

BACKGROUND

Staff absenteeism and presenteeism incur high costs to the NHS and are associated with adverse health outcomes. The main causes are musculoskeletal complaints and mental ill-health, which are potentially modifiable, and cardiovascular risk factors are also common. We will test the feasibility of an RCT to evaluate the clinical and cost-effectiveness of an employee health screening clinic on reducing sickness absenteeism and presenteeism.

METHODS

This is an individually randomised controlled pilot trial aiming to recruit 480 participants. All previously unscreened employees from four hospitals within three UK NHS hospital Trusts will be eligible. Those randomised to the intervention arm will be invited to attend an employee health screening clinic consisting of a screening assessment for musculoskeletal (STarT MSK and STarT Back), mental (PHQ-9 and GAD-7) and cardiovascular (NHS Health Check if aged ≥ 40, lifestyle check if < 40 years) health. Screen positives will be given advice and/or referral to recommended services. Those randomised to the control arm will receive usual care. Participants will complete a questionnaire at baseline and 26 weeks; anonymised absenteeism and staff demographics will also be collected from personnel records. The co-primary outcomes are as follows: recruitment, referrals and uptake of recommended services in the intervention arm. Secondary outcomes include the following: results of screening assessments, uptake of individual referrals, reported changes in health behaviours, acceptability and feasibility of intervention, indication of contamination and costs. Outcomes related to the definitive trial include self-reported and employee records of absenteeism with reasons. Process evaluation to inform a future trial includes interviews with participants, intervention delivery staff and service providers receiving referrals. Analyses will include presentation of descriptive statistics, framework analysis for qualitative data and costs and consequences presented for health economics.

DISCUSSION

The study will provide data to inform the design of a definitive RCT which aims to find an effective and cost-effective method of reducing absenteeism and presenteeism amongst NHS staff. The feasibility study will test trial procedures, and process outcomes, including the success of strategies for including underserved groups, and provide information and data to help inform the design and sample size for a definitive trial.

Resumo Objetivo: descrever indicadores de absenteísmo-doença entre trabalhadores de indústria de petróleo. Métodos: estudo de coorte retrospectiva, realizado de 2012 a 2016, com dados secundários de prontuários médicos e de bases de dados da empresa. Foram calculados indicadores de absenteísmo por morbidade, características sociodemográficas e ocupacionais. Resultados: participaram 2.028 trabalhadores, do sexo masculino (87,6%), com idade maior ou igual a 50 anos (46,9%), nível médio de escolaridade (49,2%) e que trabalhavam em atividade não-operacional (65,1%). A incidência acumulada de afastamento do trabalho foi de 71,5% e a taxa de incidência de 25,8/100 pessoas-ano. Maiores taxas foram observadas entre mulheres (31,6), trabalhadores com 50 ou mais anos (29,9), 30 ou mais anos de serviço (31,9), menor escolaridade (29,2), em atividade operacional (27,9) e horário regular (26,1). Doenças osteomusculares (n=2001), respiratórias (n=1016) e digestivas (n=967) foram responsáveis pelo maior número de licenças. Os maiores números de dias de ausência ao trabalho foram por doenças osteomusculares (n=11640), lesões por causas externas (n=6267) e transtornos mentais (n=5042). Dor lombar foi o diagnóstico com maior número de dias de absenteísmo (n=3632). Conclusão: mulheres, trabalhadores com mais tempo de serviço e de menor escolaridade devem ser alvo de programas de saúde que visem o controle das morbidades identificadas.

Musculoskeletal diseases are the main cause of sick leave among oil industry workers in Brazil: results of a cohort study

Abstract Objective: to describe the incidence of sickness absence among workers of an oil industry in Brazil. Methods: retrospective cohort study conducted with 2,028 workers. Study data were obtained from workers’ medical records from 2012 to 2016. Indicators of absenteeism were calculated by sociodemographic characteristics, occupational characteristics, and morbidity. Results: of the participants, 87.6% were men, 49.2% with high school educational level, 46.9% aged 50 years or older, 65.1% worked in non-operational activities. The cumulative incidence of sick leave was 71.5% and its incidence rate, 25.8 per 100 person-years. We found the highest incidence rates amongst women (31.6), workers aged 50 years or older (29.9), lower educational attainment (29.2), work experience spanned 30 years or more (31.9), working in operational activities (27.9), and regular work schedule (26.1). Musculoskeletal (n=2,001), respiratory (n=1,016), and digestive diseases (n=967) were responsible for the largest number of sick leaves. The highest number of absence days was due to musculoskeletal diseases (n=11,640), followed by injuries (n=6,267) and mental disorders (n=5,042). Low back pain diagnostic was responsible for the greatest number of absence days (n=3,632). Conclusions: health programs aimed at controlling the identified morbidities should target women, those with longer work experiences, and those with lower educational attainment.

Risk factors for absenteeism due to musculoskeletal diseases in workers in the judiciary sector

Introduction

Musculoskeletal diseases represent an important health problem for workers, due to the degree of suffering caused by pain and to the high frequency of absenteeism.

Objectives

To identify risk factors for absenteeism due to musculoskeletal disease in employees at a judiciary court and to describe incidence, frequency, and duration of sick leaves.

Methods

This is a 6-year follow-up study conducted in the state of Bahia, Brazil. The dependent variable was absenteeism, measured by the time of the first sick leave in the period. The Kaplan-Meier method was used to estimate survival functions, whereas risk factors for absenteeism were obtained by Cox regression.

Results

Overall, 594 workers took sick leaves, with an incidence of 23% at the end of the period. The most frequent diagnoses were back pain (38.5%), shoulder lesions (11.7%), and synovitis and tenosynovitis (8.8%). Cases of one episode of sick leave per worker over the 6 years predominated (42.8%). Cox regression multivariate analysis identified the following variables as posing the greatest risk for sick leave: female sex (hazard ratio 1.39), age older than 40 years (hazard ratio 2.57), judicial technician workers (hazard ratio 1.48), and administrative workers (hazard ratio 1.30).

Conclusions

Women, older adults, and individuals who hold technical positions are worthy of attention from health management department of the court, since they presented the highest rates of incapacity to work during the study period. Back pain was the main reason for musculoskeletal disability.

Smoking and Long-Term Sick Leave in a Japanese Working Population: Findings of the Japan Epidemiology Collaboration on Occupational Health Study

Background

Few studies have investigated the association between tobacco smoking and sick leave (SL) in Japan.

Methods

We followed 70 896 workers aged 20–59 years (60 133 males, 10 763 females) between April 2012 and March 2017. A Cox proportional hazards model was used to investigate the associations between smoking (smoking status and intensity) and long-term SL (ie, SL lasting ≥30 consecutive days). Cause-specific analyses were also conducted.

Results

A total of 1777 people took long-term SL during a follow-up of 307 749 person years. Compared with never-smokers, current smokers were at a higher risk of long-term SL (hazard ratio [HR] = 1.32; 95% confidence interval [CI] = 1.19 to 1.48). Cause-specific analyses revealed that current smoking was associated with a higher risk of SL due to all physical disorders (HR = 1.44, 95% CI = 1.22 to 1.69), cancer (HR = 1.49, 95% CI = 1.10 to 2.01), cardiovascular disease (CVD; HR = 2.16, 95% CI = 1.31 to 3.55), and injuries/external causes (HR = 1.83, 95% CI = 1.31 to 2.58). Former smokers were at a higher risk of SL due to cancer at a borderline significance level (HR = 1.38, 95% CI = 0.99 to 1.92). Low-intensity smoking (ie, 1–10 cigarettes smoked per day) was associated with all-cause SL, SL due to CVD, and SL due to injuries/external causes compared with never-smokers.

Conclusion

In a large cohort of working-age Japanese, smoking was associated with a greater risk of long-term SL. Greater effort is needed to mitigate disease burden associated with smoking at workplace in Japan.

Implications

Our study contributes to the literature on the association between smoking and SL in several ways. First, the study was conducted among a Japanese working population. While the association has been extensively studied in Western setting, few attempts have been made elsewhere. Second, cause-specific analyses were undertaken in our study. Third, we paid attention to the effect of low-intensity smoking on SL given that there is growing evidence of an elevated health risk associated with low-intensity smoking.

P, Neupane S. Process of Work Disability: From Determinants of Sickness Absence Trajectories to Disability Retirement in A Long-Term Follow-Up of Municipal Employees

Work disability may originate early during work history and involve sickness absences (SA) and eventually permanent disability. We studied this process over 15 years. Questionnaire data collected in 1981 on health, working conditions, and lifestyle of Finnish municipal employees aged 44-58 years (n = 6257) were linked with registers on SA (≥10 workdays), disability pension, and death from the period 1986-1995. Trajectory analysis was used to assess development in SA (days/year) over 5 years (1981-1985). We analyzed determinants of the trajectories with multinomial regression, while trajectory membership was used as a predictor of disability pension (DP) during the subsequent 10 years in survival analysis. Three SA trajectories emerged: increasing (women: 6.8%; men: 10.2%), moderate (21.2%; 22.7%), and low. In a mutually adjusted model, the increasing trajectory in women was associated with baseline musculoskeletal (MSD), mental and respiratory disorders, injuries, obesity, sleep problems, and low exercise (effect sizes OR > 2), and in men with MSD, sleep problems, smoking, low exercise, and non-satisfaction with management. The moderate trajectory associated with MSD, 'other somatic disorders', sleep problems, and awkward work postures in both genders; in women, also overweight, cardiovascular and respiratory morbidity, and (inversely) knowledge-intensive work, and in men, smoking and mental disorders were thus associated. Ten-year risks of DP contrasting increasing vs. low SA were more than 10-fold in both genders and contrasting moderate vs. low SA 3-fold in women and 2-fold in men. These findings emphasize the need for early identification of workers with short-term problems of work ability and interventions regarding lifestyle, health, and working conditions, to help prevent permanent disability.

Is low-back pain a limiting factor for senior workers with high physical work demands? A cross-sectional study

BACKGROUND

Low-back pain (LBP) is highly prevalent among senior workers and may affect work ability, especially among those with hard physical work. This study determined the joint association of LBP intensity and physical work demands with work limitiations due to pain in senior workers.

METHODS

In the SeniorWorkingLife study (2018), 11,738 senior workers (≥50 years) replied to questions about physical work demands, LBP intensity, and work limitations due to pain. Using logistic regression analyses and controlling for potential confounders, associations between the physical work demands and LBP intensity (interaction) with work limitiations due to pain (outcome) was modeled.

RESULTS

Higher LBP intensity, as well as higher physical work demands, significantly increased the odds of experiencing work limitiations due to pain, and these two factors interacted with each other (p < 0.0001). In analyses stratified for LBP intensity, higher physical work demands gradually increased the odds of experiencing work limitiations due to pain.

CONCLUSIONS

Senior workers with a combination of physically demanding work and LBP are more affected by their pain during everyday work tasks compared to workers with similar LBP-intensity in sedentary occupations. Accommodation of work demands seems especially relevant for this group of workers.

BMI and Medically Certified Long-Term Sickness Absence Among Japanese Employees

OBJECTIVE

In contrast to the association between excess weight and sickness absence (SA), the association in relation to underweight has been under-researched. This study aimed to examine the effects of BMI at both extremes of its distribution on SA.

METHODS

Data came from the Japan Epidemiology Collaboration on Occupational Health study of 77,760 workers aged 20 to 59 years (66,166 males, 11,594 females). Information was collected on medically certified long-term SA (LTSA) (i.e., SA lasting ≥ 30 consecutive days) from April 2012 to March 2017. A sex-specific Cox proportional hazards model was used to investigate the associations.

RESULTS

Among males, both obesity (hazard ratio [HR] = 1.81, 95% CI: 1.50-2.17) and underweight (HR = 1.56, 95% CI: 1.23-1.96) were significantly associated with LTSA compared with normal weight. This U-shaped association between BMI categories and LTSA was observed both for mental and physical disorders. Among females, an elevated risk was observed among those with overweight (HR = 1.54, 95% CI: 1.16-2.05).

CONCLUSIONS

In a cohort of the Japanese working-age population, both obesity and underweight were associated with a greater risk of LTSA in males. Future research should not overlook the excess risk of LTSA associated with underweight.

Cardiorespiratory Fitness and Device-Measured Sedentary Behaviour are Associated with Sickness Absence in Office Workers

Physical activity reduces the risk of several noncommunicable diseases, and a number of studies have found self-reported physical activity to be associated with sickness absence. The aim of this study was to examine if cardiorespiratory fitness, device-measured physical activity, and sedentary behaviour were associated with sickness absence among office workers. Participants were recruited from two Swedish companies. Data on sickness absence (frequency and duration) and covariates were collected via questionnaires. Physical activity pattern was assessed using ActiGraph and activPAL, and fitness was estimated from submaximal cycle ergometry. The sample consisted of 159 office workers (67% women, aged 43 ± 8 years). Higher cardiorespiratory fitness was significantly associated with a lower odds ratio (OR) for both sickness absence duration (OR = 0.92, 95% confidence interval (CI) 0.87-0.96) and frequency (OR = 0.93, 95% CI 0.90-0.97). Sedentary time was positively associated with higher odds of sickness absence frequency (OR = 1.03, 95% CI 0.99-1.08). No associations were found for physical activity at any intensity level and sickness absence. Higher sickness absence was found among office workers with low cardiorespiratory fitness and more daily time spent sedentary. In contrast to reports using self-reported physical activity, device-measured physical activity was not associated with sickness absence.

Occupational health professionals' attitudes, knowledge, and motivation concerning smoking cessation-Cross-sectional survey

OBJECTIVES

Occupational health (OH) professionals could play a prominent role in smoking cessation treatment and support (SCTS) and help individuals and workplaces become smoke free. However, their role has not been evaluated. The aim of this study was to assess differences between OH professionals' perceptions of their role in SCTS by measuring three groups of OH professionals' attitudes, knowledge, and motivation concerning SCTS.

METHODS

We collected data through an online survey completed by a cross-sectional sample of OH professionals: OH physicians (n = 182), OH nurses (n = 296), and OH physiotherapists (n = 96), collected from national trade union registers. The differences between the OH professional groups were analyzed using ANOVA, the Kruskal-Wallis, and chi-square tests.

RESULTS

The OH professionals had a positive attitude toward offering SCTS and were highly motivated to enhance their knowledge of this topic and acquire further training. The OH physicians and OH nurses assessed their current knowledge as sufficient. Conversely, the OH physiotherapists' level of knowledge was seen as insufficient. Traditionally, OH physicians and OH nurses have been responsible for carrying out SCTS, but the majority of the OH physiotherapists thought that SCTS should also be included in their job description.

CONCLUSIONS

All the OH professionals were highly motivated to deepen their knowledge of SCTS. The barriers between different professionals need to be recognized in occupational health services (OHS). OHS should organize its SCTS more effectively, strengthen their contributions to smoking cessation programs, and recognize the potential of OH physiotherapists for providing SCTS and enable them to expand their training.

The joint contribution of physical activity, insomnia symptoms, and smoking to the cost of short-term sickness absence

Physical inactivity has been associated with both insomnia symptoms and smoking. Further, they are all independently associated with increased sickness absence (SA) from work. However, joint contribution of either physical activity (PA) with insomnia symptoms or with smoking to SA and, especially, their direct cost for the employer is poorly understood. Therefore, we aimed to examine these joint associations with short-term (<15 days) SA cost. The Helsinki Health Study is a cohort of midlife employees of the City of Helsinki, Finland (baseline n = 8960, response rate 67%). During 2000-2002, the participants were mailed a survey questionnaire that gathered information on health behavior and sociodemographic characteristics. SA, salary, and time of employment were followed up through the employer's personnel register between 2002 and 2016 for those with a written consent to the use of their register data (78% of the participants). Individual salary data were used to calculate the direct cost of short-term SA. Data were analyzed with a two-part model. Inactive participants with frequent insomnia symptoms had 2526€ (95% CI 1736€-3915€) higher cost of short-term SA than vigorously active participants without insomnia symptoms. Furthermore, inactive smokers had 4166€ (95% CI 2737€-5595€) higher cost for the employer over the follow-up than vigorously active non-smokers. In conclusion, this study showed that PA and insomnia symptoms as well as PA and smoking are jointly associated with short-term SA cost. The results emphasize encouraging employers to improve work environments so that they promote active lifestyle, good sleep, and non-smoking in order to reduce the cost of SA.

Leisure-time physical activity and absenteeism

Regular physical activity has a significant impact on health. There is scientific evidence for prescription of exercise in the treatment of at least 26 different chronic non-communicable diseases. Furthermore, it has an indirect role in the preservation of work capacity. The aim of this study was to review the published results of research on the relationship between leisure-time PA and absenteeism due to sickness. Medline database was searched using the keywords "leisuretime physical activity AND (sick leave OR sickness absence OR absenteeism)". Fifteen studies were included in the final analysis. A negative correlation between leisure-time PA and absenteeism due to sickness in working population was determined in 11 studies. The results support the inclusion of PA promotion in the programmes intended to reduce absenteeism prevalence, the latter being an important public health issue.

The joint associations of smoking and obesity with subsequent short and long sickness absence: a five year follow-up study with register-linkage

Background

Both smoking and obesity are separately associated with sickness absence. Unhealthy lifestyle habits and health conditions may occur concurrently yet studies focusing on their joint association are few. This study examined the joint associations of smoking and obesity with sickness absence (SA).

Methods

A mail survey among employees of the City of Helsinki, Finland, during 2000–2002 included data on obesity, smoking and covariates (N = 8960, response rate 67%, 80% women). These data were prospectively linked with register data on self- (1–3 days) and medically certified (4 days or longer) SA among those consenting to the linkage (n = 6986). Pregnant, underweight and those with missing data on key variables were excluded (n = 138). The total number of participants included in the analyses was 6847. The follow-up time was 5 years. Poisson regression was used to calculate rate ratios (RR).

Results

Among women and men smoking and obesity were associated with self-certified SA. Among women there was a joint association with self-certified SA (obese smokers RR 1.81, 95% CI 1.59–2.07).

Among women and men smoking and obesity were jointly associated with medically certified SA (for obese smoking women RR 2.23, 95% CI 1.93–2.57, for obese smoking men RR 2.69, 95% CI 2.03–3.55). Associations remained after adjustments for socioeconomic position, working conditions, health behaviours and self-rated health.

Conclusion

Both smoking and obesity are jointly associated with all lengths of sickness absence. Support measures for smoking cessation and prevention of obesity could likely to reduce SA.

Physical activity and unplanned illness-related work absenteeism: Data from an employee wellness program

BACKGROUND

Illness-related absenteeism is a major threat to work productivity. Our objective was to assess the relationship between physical activity and unplanned illness-related absenteeism from work.

METHODS

We implemented physical activity program for sedentary non-clinician employees of a tertiary medical center. Financial rewards were available for reaching accelerometer-measured ambulatory physical activity goals over a 24-week period. We categorized participants into three groups based on mean levels of physical activity: low (0-74 min/week), medium (75-149 min/week) and meeting CDC guidelines (≥150 min/week). We built a multivariable Poisson regression model to evaluate the relationship between physical activity and rates of unplanned illness-related absenteeism.

RESULTS

The sample consisted of 292 employees who participated in the program. Their mean age was 38 years (SD 11), 83% were female, and 38% were obese. Over the 24 intervention weeks, participants engaged in a mean of 90 min/week (SD 74) of physical activity and missed a mean of 14 hours of work (SD 38) due to illness. Unplanned absenteeism due to illness was associated with physical activity. As compared to the group meeting CDC guidelines, in multivariable analyses those in the medium physical activity group had a 2.4 (95% CI 1.3-4.5) fold higher rate of illness-related absenteeism and those in the lowest physical activity group had a 3.5 (95% CI 1.7-7.2) fold higher rate of illness-related absenteeism.

DISCUSSION

Less physical activity was associated with more illness-related absenteeism. Workforce-based interventions to increase physical activity may thus be a promising vehicle to reduce unplanned illness-related absenteeism.

Association between V̇O2max, handgrip strength, and musculoskeletal pain among construction and health care workers

Background

Construction and health care workers have a high prevalence of musculoskeletal disorders, and they are assumed to have physically demanding jobs. Profession- and gender-specific associations between individual capacity and musculoskeletal pain have not been sufficiently investigated. The main aim of this study was to examine the association between individual capacity (maximal oxygen uptake (V̇O_2max) and handgrip strength) and musculoskeletal pain among construction and health care workers.

Methods

This cross-sectional study examined 137 construction and health care workers (58 women and 79 men) with a mean age of 41.8 years (standard deviation 12). Aerobic capacity was indirectly assessed by the Åstrand cycle test, and strength was assessed by a handgrip test. Musculoskeletal pain was described by total pain, divided into neck, shoulder, and low back pain, during the last 12 months, and it was dichotomized in below or above 30 days. Logistic regression was used to analyse the associations between V̇O_2max, strength, and musculoskeletal pain in the total study sample and separately for construction and health care workers. Analyses were adjusted for age, gender, body mass index (BMI), and selected mechanical and psychosocial factors.

Results

Every second participant (51.8%) reported pain in either neck, shoulders or low back for more than 30 days during the last 12 months. Among the health care workers, a small but significant association was found between a high V̇O_2max, high handgrip strength, and a low level of musculoskeletal pain. No association was found for the construction workers.

Conclusions

An association between V̇O_2max, handgrip strength, and musculoskeletal pain was found for health care workers but not for construction workers. These results indicate that activities promoting individual capacity may reduce musculoskeletal pain for health care workers.

[Prevalence of physical activity in primary health care workers of Catalonia]

INTRODUCTION

Physical inactivity is the fourth leading risk factor for global mortality, and a significant percentage of the world population does not perform the necessary physical activity for health benefits. Certain professional groups are seen as an example for the general population with whom they interact. Prevalence of physical activity in health workers, one of these reference groups, is mainly unknown. The aim of this study has been to assess the prevalence of physical activity levels in Primary Health Care professionals.

MATERIAL AND METHODS

A study was conducted on the physical activity levels in Primary Health Care workers who came voluntarily for a medical examination in 2014, and completed the short version of the International Physical Activity Questionnaire activity.

RESULTS

A low level of physical activity was reported by 26.5% of those taking part, with 31.5% of the medical group indicating a low level of activity, followed by support staff (28.1%), nurses (24.7%), and finally the administrative staff (19.0%).

CONCLUSIONS

The physical activity levels of Primary Health Care staff are significantly different from those of the general reference population. The latter has a higher percentage of physical activity of mild to moderate intensity, and below the level of physical activity of high intensity. Although there seems to be a tendency to significantly lower physical activity in other health groups, we do not have sufficiently reliable data to compare them.
