The association between self-employed workers’ risk perception and use of preventive occupational physician care
Open AccessSuzanne Pees, S Orhan Pees et al.ARTICLEBMC Public Health2025
Self-employed workers (SEW) face (work-related) health risks, but their access to occupational health care is generally not well arranged. This study assesses the association between SEW’ risk perception (i.e. perceived likelihood and seriousness) of work- related health problems and work disability, and their use of preventive occupational physician (OP) care. Data were collected from 348 self-employed workers via an online questionnaire in June…

Barriers and facilitators to the implementation of workplace health promotion programs
Open AccessJennifer M D Campmans, Denise J M Smit et al.ARTICLEFrontiers in Public Health2023
Background: Workplace health promotion programs (WHPPs) can benefit the lifestyle and health of employees. However, not all WHPPs have been successful in their implementation, and thus their effectiveness. This study aimed to identify the barriers and facilitators to implementing an integrated WHPP, which targets multiple lifestyle factors at different levels (individual and organizational), from an employer's perspective. Methods: Data were coll…
Mental health of healthcare workers during the first year of the Covid-19 pandemic in the Netherlands
Open AccessMaaike van der Noordt, Karin I Proper et al.ARTICLEFrontiers in Public Health2023
Purpose: In March 2020, the WHO declared COVID-19 a pandemic. Previous virus outbreaks, such as the SARS outbreak in 2003, appeared to have a great impact on the mental health of healthcare workers. The aim of this study is to examine to what extent mental health of healthcare workers differed from non-healthcare workers during the first year of the COVID-19 pandemic. Methods: = 16,615; number of observations = 64,206). Mental health, as measured…

Views of Older Adults on Using Support to Prevent Overload in Informal Caregivers
Open AccessEline E Vos, Simone R de Bruin et al.ARTICLEHealth & Social Care in the…2023
Older care recipients living at home increasingly rely on support from informal caregivers. As informal caregivers often combine these caregiving tasks with other tasks, such as paid work, they are at risk of becoming overloaded. To decrease informal caregiver burden, different forms of support are available that also affect older care recipients’ lives, such as respite care, technology, or home care. The aim of this qualitative study was to obta…
The mediating role of physical activity and sedentary behavior in the association between working from home and musculoskeletal pain during the Covid-19 pandemic
Open AccessGary W Ladd, Bette Loef et al.ARTICLEFrontiers in Public Health2022
Home and hybrid workers were more likely to have pain in the upper musculoskeletal system during the COVID-19 pandemic than location workers, which was partly mediated by increased sedentary behavior, but not by reduced physical activity. Measures to reduce sedentary time in home workers may contribute to preventing musculoskeletal pain
The Implementation of Preventive Health Measures in Small- and Medium-Sized Enterprises—A Combined Quantitative/Qualitative Study of Its Determinants from the Perspective of Enterprise Representatives
Open AccessFriederike E Benning, Sandra H van Oostrom et al.ARTICLEInternational Journal of…2022
The workplace is an ideal environment for promoting workers' health. Nevertheless, preventive health measures are insufficiently implemented, especially in small and medium-sized enterprises (SMEs) with up to 250 employees. The aim of this study was to investigate determinants for the implementation of measures to prevent musculoskeletal and mental health disorders from the perspective of enterprise representatives in Dutch SMEs. An online survey…
Changes in Fruit and Vegetable Consumption and Leisure Time Physical Exercise after a Citizen Science-Based Worksite Health Promotion Program for Blue-Collar Workers
Open AccessSophie van der Feltz, Henk F van der Molen et al.ARTICLEInternational Journal of…2022
Blue-collar workers have, on average, poorer health than white-collar workers. Existing worksite health promotion programs (WHPPs) are often not successful among blue-collar workers. This study evaluates the effect of the Citizen Science-based WHPP on the targeted lifestyle behaviors among construction workers. The data of 114 participants were retrieved from questionnaires before (T0) and after (T1) the WHPP. Outcome measures were mean and categ…
The process evaluation of a citizen science approach to design and implement workplace health promotion programs
Open AccessLisa Lelie, Henk F van der Molen et al.ARTICLEBMC Public Health2022
Workers were satisfied with the involvement in WHPPs. Organizational and social cultural factors were barriers for the CS approach and its reach. Involvement and interaction in WHPPs were particularly experienced in small grouped sessions. Consequently, contextual and personal factors need be considered in the design and implementation of WHPPs with CS approach among blue-collar workers

It’s Like Juggling, Constantly Trying to Keep All Balls in the Air”
Open AccessEline E Vos, Eline Vos et al.ARTICLEInternational Journal of…2021
Many informal caregivers of older adults combine their caregiving tasks with a paid job. Adequate support is important to enable them to combine paid work with caregiving, while maintaining their health and wellbeing. To date, however, knowledge about working caregivers' support needs is fragmented. This study, therefore, aimed to obtain more insight into the support needs of working caregivers of older adults. We conducted six online semi-struct…
The mediating role of unhealthy behavior in the relationship between shift work and perceived health
Open AccessKarin I Proper, Eva A Jaarsma et al.ARTICLEBMC Public Health2021
Shift workers did not report lower mental or physical health than non-shift workers. Though mediation effects of unhealthy behavior were observed in the relationship between shift work and perceived health, these small effects had minor public health relevance
Adapting Citizen Science to Improve Health in an Occupational Setting
Open AccessMandy van den Berge, Gerben Hulsegge et al.ARTICLEInternational Journal of…2020
Health interventions often do not reach blue-collar workers. Citizen science engages target groups in the design and execution of health interventions, but has not yet been applied in an occupational setting. This preliminary study determines barriers and facilitators and feasible elements for citizen science to improve the health of blue-collar workers. The study was conducted in a terminal and construction company by performing semi-structured …
Single transitions and persistence of unemployment are associated with poor health outcomes
Open AccessGerrie-Cor Herber, Gerrie-Cor M Herber et al.ARTICLEBMC Public Health2019
Single transitions into unemployment and persistent unemployment are associated with poor mental and general health, obesity, and to a lesser extend smoking. Our study suggests that re-employment might be an important strategy to improve health of unemployed individuals. The relatively extensive Dutch social security system may explain that the economic recession did not modify these associations

An exploratory study of associations of physical activity with mental health and work engagement
Open AccessJantien van Berkel, Karin I Proper et al.ARTICLEBMC Public Health2013
Although the beneficial effects of MVPA on the negative side of MH (i.e. mental disorders) have been established in previous studies, this study found no evidence for the beneficial effects of MVPA on positive side of MH (i.e. well-being). The possible difference in how the physical activity-mental health relationship works for negative and positive sides of MH should be considered in future studies
Measurement error of waist circumference

Ethical considerations of worksite health promotion
Open AccessJantien van Berkel, Agnes Meershoek et al.ARTICLEBMC Public Health2014
All stakeholders, including employees, should be given a voice in developing, implementing and evaluating worksite health promotion. Moreover, since stakeholders agree on lifestyle being the responsibility of the employee, but disagree on what this responsibility means (duty versus autonomy), it is of utmost importance to examine the discourse of stakeholders. This way, ambivalence in relationships between stakeholders could be prevented
A qualitative study of the anticipated barriers and facilitators to the implementation of a lifestyle intervention in the dutch construction industry
Open AccessSusanne Tonnon, S C Tonnon et al.ARTICLEBMC Public Health2014
The findings suggest that employees can be motivated to sign up for a lifestyle intervention by tailoring the implementation strategy to various subgroups within the target group. Occupational physicians can be motivated to refer employees for the intervention by making a referral personally and professionally rewarding
