Exposure to occupational hazards for pregnancy and sick leave in pregnant workers: a cross-sectional study

Hospital managers' perspectives on pregnancy policy and work adjustments: A cross-sectional study

BACKGROUND

Risk assessment and work adjustment according to EU legislation may safeguard pregnant employees and their offspring. Knowledge on management perspectives in relation to implementation of protective measures is limited.

OBJECTIVES

The primary aim was to describe Danish hospital managers' engagement in pregnancy policy and work adjustment for pregnant employees. The secondary aim was to investigate how managers' characteristics and the setting affect engagement and behaviour.

METHODS

This was a cross-sectional study of survey data from 212 managers. Outcomes were within dimensions of health promotion, pregnancy policy, work adjustment, collaboration, manager support, and sick leave. Logistic and ordinal logistic regression models were applied to identify associations between background information and outcomes.

RESULTS

Of the managers included, 84% arranged meetings and 76% conducted occupational risk assessment. Most managers (96%) engaged in dialogue with the employees before sick leave. Most managers felt competent in providing guidance for pregnant employees and 99% considered work adjustment important, mainly to safeguard mothers and children. The self-reported data showed positive associations between female managers and feeling competent to guide the employee. Further, management training was associated with meetings with pregnant employees. Seniority was associated with feeling competent to guide and dialogue. Midwifery support was associated with competence in guiding employees about risk factors.

CONCLUSION

Work adjustment and risk assessment for pregnant employees are considered a priority by Danish hospital managers. Overall, managers feel competent guiding pregnant employees. However, managers experience midwifery support beneficial for the guidance of pregnant employees.

Workplace intervention among pregnant hospital employees - A protocol of a cluster randomized trial

BACKGROUND

Sick leave during pregnancy is frequent and 36 % of Danish pregnant employees are on sick leave > 14 days. Health care professionals are considered a risk population. This intervention applies preventive sessions including the pregnant employee, her manager and a midwife in addition to usual practiceat Aarhus University Hospital, Denmark (AUH). It is hypothesised that pregnant employees who participate in preventive sessions will have less sick leave and report better wellbeing compared to the reference group.

METHODS

All departments at AUHare cluster randomized. A total of 25 and 24 departments are allocated to the intervention and reference group, respectively. The intervention is protocolled with preventive sessions in addition to usual practice. The reference group receives usual practice. The primary outcome is mean number of days on sick leave during pregnancy. Secondary outcomes are wellbeing measured as physical and mental health, general work ability, work-life balance, manager support, and completed work adjustments during pregnancy. Data on sick leave will be collected from the hospital payment system and survey data will be collected at inclusion and follow-up.

DISCUSSION

This study will contribute to limited experimental research aimed to reduce sickness leave during pregnancy. The overall strength is the study design with easy access to study participants within a large hospital. The main limitation of the study is the high complexity of the study.

TRIAL REGISTRATION

The trial is registered in ClinicalTrials.gov with ID number 29-2019-03.

A narrative review on factors associated with job interruption during pregnancy

Most women continue to work during pregnancy. However, some of them have to stop working before giving birth. Absence from work poses several challenges for employers and employees, as well as for society. The literature on absence from work during pregnancy and its determinants remains inconsistent and rather scarce. To conduct a narrative literature review on the factors associated with work interruption and on existing interventions aimed at reducing the absence prevalence during pregnancy. The review refers to published peer-reviewed articles dealing with all types of work interruption among pregnant women. Keyword searches were performed in the electronic databases PubMed, EMBASE, and Google Scholar, covering the period 2000-2022. The review, which includes 42 papers, presents a broad and comprehensive picture of factors and interventions associated with absence from work among pregnant workers. The factors appear at different levels and include factors related to the pregnant women, such as individual health and socio-demographic factors; employer and workplace-related factors, such as risk exposures and working conditions; factors related to the role of the healthcare provider; and factors related to the national context (social benefits/insurance). The determinants of absence from work during pregnancy are complex and multifactorial and involve multiple stakeholders. The discussion addresses gaps and needs in the literature on pregnancy at work and in the field of occupational health. Int J Occup Med Environ Health. 2023;36(3):303-23.

Women's Health and Working Life: A Scoping Review

Women's health matters for participation in working life. The objective of this study was to explore female physiology in a work-life context and to investigate possible associations between women's health, sickness absence and work ability. A scoping review was conducted to develop a systematic overview of the current research and to identify knowledge gaps. The search strategy was developed through a population, concept and context (PCC) model, and three areas of women's health were identified for investigation in the context of work. A total of 5798 articles were screened by title and abstract and 274 articles were screened by full text; 130 articles were included in the review. The material included research from 19 countries; the majority of the studies used quantitative methods. The results showed an impact on the occupational setting and an association between sickness absence, work ability and all three areas of women's health, but a holistic and overall perspective on female biology in the work context is missing. This review calls for more knowledge on health and work and possible gender differences in this regard. Women's health and working life involve a complex connection that has the potential to develop new knowledge.

Sick leave during pregnancy and occupational factors: a systematic review

BACKGROUND

The reported prevalence of sick leave (SL) during pregnancy is high among European pregnant workers (PW). The causes of SL during pregnancy are complex, and further research is necessary to explain their occurrence.

AIMS

Summarize the evidence for an association between occupational risks for pregnancy and SL.

METHODS

A systematic review was conducted by two independent reviewers using PRISMA guidelines. Two databases (Pubmed, Embase) were interrogated between January 1990 and November 2021. The search question integrated key terms according to the PICOS acronym (free terms, MeSH, EMTREE). The quality of the selected studies was assessed according to the Methodological Index for Non-randomized Studies score.

RESULTS

This review assessed 11 epidemiological studies. Overall, the mean Methodological Index for Non-Randomized Studies score was 11, indicating moderate study quality. The results of the limited number of studies showed limited evidence for associations between psychosocial and physical work-related risk factors and the occurrence of SL among PW. However, this assessment was strengthened by the observation in several studies of a dose-response relationship between the number of occupational risks during pregnancy and SL.

CONCLUSIONS

The analysis of this review implicates PW'S exposure to occupational risks in the occurrence of SL. However, the few studies that support this conclusion have provided weak evidence; thus, further research is necessary.

A survey of Australian and New Zealand medical parents' experiences of infertility, pregnancy, and parenthood

Objective

To describe the incidence of infertility, pregnancy complications, and breastfeeding practices among Australian and New Zealand doctors and identify factors associated with increased pregnancy complication rates.

Methods

A survey of ANZ doctors using an online questionnaire during November 2021.

Results

One thousand ninety-nine completed responses were received. The median age of female doctors at the time of their first child was 32.4. Fertility testing was undertaken by 37%, with 27% having in vitro fertilization. More than 60% of respondents delayed family planning due to work. Pregnancy loss occurred in 36% of respondents, and 50% suffered a pregnancy complication. There were significant differences between specialists, with surgeons working longer hours before and after pregnancy, but having greater access to maternity leave than general practitioners.

Conclusion

Female doctors delay starting and completing their family due to work-related demands and structural biases in career progression, which may result in higher infertility and pregnancy complication rates.

Evaluation of a pilot consultation for maternity protection at work in Switzerland

STUDY AIMS

Switzerland's Labour Law and its Ordonnance on Maternity Protection aim to protect the health of pregnant employees and their unborn children while enabling them to continue to pursue their professional activities. Some companies encounter difficulties implementing the law's provisions. The Department of Occupational and Environmental Health, part of the Center for Primary Care and Public Health (Unisanté), has provided specialist occupational medicine consultations for pregnant employees since 2015. This study aimed to evaluate how well Swiss' maternity protection legislation is implemented by examining a list of relevant indicators measured during the occupational health consultation. The study also sought to investigate the consultation support provided to the relevant stakeholders and the adjustments made to pregnant employees' working conditions.

METHODS

Descriptive variables and indicators relative to the application of the Swiss maternity protection legislation for 83 pregnant employees were collected during the consultation's pilot phase (between 2015 and 2016). Descriptive statistics and cross-analyses of these indicators were made.

RESULTS

Most pregnant employees faced multiple exposures to occupational risks. Preventive risk analyses were rare. Few adjustments to workstations were proposed. We found a tendency for employees to leave their workstations early on in their pregnancies due to sick leave certificate prescriptions. Specialist consultation and collaboration with occupational health physicians to recommend interventions for pregnant employees can provide significant benefits and help some pregnant women to continue at their workstations with appropriate adjustments.

DISCUSSION

A specialised occupational health consultation is a useful instrument for identifying occupational hazards for both the pregnant woman and her unborn child. It is also an opportunity to explain employers' legal responsibilities and obligations to safeguard the health of their pregnant employees and to give specific advice for their company's situation. This consultation also enables employers to maintain their employees' valuable professional competencies in the workplace for as long as possible. Finally, occupational health consultation helps and supports healthcare providers who must, according to the law, make decisions about whether pregnant employees can continue working safely or not.

Evaluation of a blended care programme for caregivers and working pregnant women to prevent adverse pregnancy outcomes: an intervention study

Objective

Work-related activities can be a risk factor for pregnancy complications such as preterm birth. This study evaluates the effectiveness of a blended care programme, Pregnancy and Work, that provides pregnant workers and their obstetrical caregivers with advice on work adjustment.

Methods

Women less than 20 weeks of gestation, in paid employment or self-employed, in the care of four participating hospitals and their referring midwifery practices in the Netherlands received either the blended care programme (n=119), consisting of a training for professionals and a mobile health application, or care as usual (n=122) in a controlled intervention study with a follow-up in intervention and control populations. All participants completed three questionnaires concerning health and working conditions at 16, 24 and 32 weeks of pregnancy. Primary outcome was the percentage of women who received advice from their obstetrical caregiver about work adjustment. Secondary outcomes were work status, realised work adjustment and working conditions. Groups were compared using univariate and multivariate regression analyses.

Results

A total of 188 (78%) completed all three questionnaires. In the blended care group, women received more advice from obstetrical caregivers to adjust their work than in the control group, 41 (39%) vs 21 (18%) (adjusted relative risk (aRR) 2.2, 95% CI 1.4 to 3.4), but less from their employer 8 (8%) vs 31 (28%) (aRR 0.29, 95% CI 0.14 to 0.61). There were no significant differences in realised work adjustments. At 24 weeks, 30% of the pregnant women in both groups continued to work in hazardous workplaces.

Conclusion

Among working pregnant women, the blended care intervention increases advice on work adjustment given by midwives and obstetricians, but does not lead to more work adjustments.

[Working at the hospital during pregnancy: A descriptive national cross-sectional study in France]

OBJECTIVE

The objective of the article is to describe the follow-up of pregnancies at work and occupational exposure to potential risks for pregnancy.

METHODS

A descriptive cross-sectional study was performed from April 1, 2017 to October 31, 2017 in the occupational health departments of French hospitals. After delivery and at the time of returning to work, 1,165 eligible workers were interviewed by occupational health physicians (OHPs). Socio-demographic information was self-reported. Occupational exposures were assessed by an OHP. Birth weight, gestational age, and sick leaves were also collected.

RESULTS

Among recruited workers, 51.8% were exposed to more than 5 occupational hazards. Biological and physical hazards were the most common hazards at the workplace. Note that heavy lifting ≥ 15 kg concerned 9.5% of workers. Only 20.1% of workers had a specific "pregnancy at work" medical visit with OHP during pregnancy; 26.8% benefited from workstation adjustments. In contrast, the level of sick leaves was high (86.7%).

CONCLUSIONS

Our data suggest that pregnant workers in hospitals must be strictly supervised.

Implementation of maternity protection legislation: Gynecologists' perceptions and practices in French-speaking Switzerland

Background

In several countries, maternity protection legislations (MPL) confer an essential role to gynecologist-obstetricians (OBGYNs) for the protection of pregnant workers and their future children from occupational exposures. This study explores OBGYNs’ practices and difficulties in implementing MPL in the French-speaking part of Switzerland.

Methods

An online survey was sent to 333 OBGYNs. Data analysis included: 1) descriptive and correlational statistics and 2) hierarchical cluster analysis to identify patterns of practices.

Results

OBGYNs evoked several problems in MPL implementation: absence of risk analysis in the companies, difficult collaboration with employers, lack of competencies in the field of occupational health. Preventive leave was underused, with sick leave being prescribed instead. Training had a positive effect on OBGYNs’ knowledge and implementation of MPL. Hierarchical cluster analysis highlighted three main types of practices: 1) practice in line with legislation; 2) practice on a case-by-case basis; 3) limited practice. OBGYNs with good knowledge of MPL more consistently applied its provisions.

Conclusion

The implementation of MPL appears challenging for OBGYNs. Collaboration with occupational physicians and training might help OBGYNs to better take on their role in maternity protection. MPL in itself could be improved.

Night work and sick leave during pregnancy: a national register-based within-worker cohort study

Objective

The aim of our study was to investigate the acute effect of night work during pregnancy on the risk of calling in sick the following day using register-based information and the workers as their own controls.

Methods

Using the payroll-based national Danish Working Hour Database, including all public hospital employees in Denmark, we identified 9799 pregnant women with ≥1 day shift and ≥1 night shift and ≥1 day of sick leave during the first 32 pregnancy weeks from January 2007 to December 2013. We performed fixed effects logistic regression, that is, within-worker comparisons, of the risk of sick leave of any duration starting within 24 hours after night shifts of different length versus day shifts.

Results

Most of the participants were nurses (64%) or physicians (16%). We found an increased relative risk of sick leave following night shifts compared with day shifts during all pregnancy trimesters. The risk was highest for night shifts lasting >12 hours (OR 1.37, 95% CI 1.15 to 1.63 for nurses; OR 1.87, 95% CI 1.69 to 2.08 for physicians) and among women aged >35 years (OR 1.42, 95% CI 1.24 to 1.63).

Conclusion

Among Danish public hospital employees night shifts during pregnancy, especially shifts longer than 12 hours, increased the risk of calling in sick the following day independent of personal factors and time-invariant confounders in all pregnancy trimesters.

[Occupational risks during pregnancy: Feedback from occupational medical services]

OBJECTIVES

To describe the follow-up of pregnancies at work and exposures to pregnancy occupational hazards.

METHODS

A cross-sectional study was performed between January and December 2014 in occupational health services of Languedoc-Roussillon region. Eligible workers were interviewed by occupational health physicians (OHPs) after delivery and at the time of returning to work (exposure, anticipation, prevention, communication, sick leave). Occupational skill levels were classified according to the French standard classification of occupations (version 2003) from the French National Institute of Statistics. Socioeconomic deprivation was assessed using the Evaluation of Deprivation and Inequalities in Health Examination (EPICES) individual scale.

RESULTS

A total of 1347 workers were recruited. The mean age was at 30.7±4.5 years. Among pregnant workers, there were 54.2% of employees, 30.7% of intermediate occupations, 10.4% of managers and, 4.7% of manual workers. Twenty-two percent of workers were classed as deprived. Also, 43.2% of workers were exposed to three or more occupational hazards during pregnancy. Only 17.7% of workers had medical visits with OHP during pregnancy and 14.7% benefited from workstation adjustments. In contrast, the level of sick leaves was high (74.2%).

CONCLUSION

Our results argue for the need to follow pregnancies at work. However, the low level of prevention activities and the high level of sick leaves raise the question of the management of pregnant women at work.
