RESUMEN

Workplace injuries constitute a serious and growing public health concern worldwide. Despite work-related injuries being highly common, especially among workers in the manufacturing industry, their growing complexities are not adequately addressed in the current literature. Therefore this study aims to investigate the association between sociodemographic, workplace, and behavioral characteristics with work-related injuries among large-scale factory workers in Ethiopia. A cross-sectional study was conducted from February to April 2020 with 457 workers selected from large-scale factories in Addis Ababa, the capital of Ethiopia. Survey data included sociodemographic characteristics, working and safety conditions, and behavioral factors as predictors of occupational injuries. A logistic regression model was fitted to estimate the probability of injury and identify its associated factors. The 12-month prevalence of work-related injuries was 25%. Most injuries occurred at midnight (8.8%). Factors associated with work-related injury were excessive working hours (OR = 3.26; 95%CI: 1.26-8.41), cigarette smoking (OR = 2.72; 95%CI: 1.22-6.08), and manual handling (OR = 2.30; 95%CI: 1.13-4.72). Use of personal protective equipment reduced the odds of injury (OR = 0.42; 95%CI: 0.21-0.83). Although our estimated prevalence of occupational injury was lower than that found in other studies, our findings suggest that actions on modifiable conditions must be taken to reduce the burden of workplace injuries in Ethiopia. The results could inform preparedness and policy efforts aimed at improving worker safety and health.

Los accidentes laborales constituyen un grave y creciente problema de salud pública mundial. Aunque este tipo de accidente es frecuente, especialmente entre los trabajadores de las industrias manufactureras, su creciente complejidad no ha sido abordada adecuadamente en la literatura actual. El objetivo de este estudio fue analizar la asociación entre las características sociodemográficas, ambientales y conductuales y los accidentes laborales en trabajadores de grandes fábricas de Etiopía. Se trató de un estudio transversal, realizado de febrero a abril de 2020 con 457 trabajadores de grandes fábricas en Adís Abeba, la capital de Etiopía. Los datos recopilados contenían características sociodemográficas, condiciones de trabajo, de seguridad y factores conductuales como predictores de accidentes laborales. Se utilizó un modelo de regresión logística para estimar la probabilidad de lesión e identificar sus factores asociados. La prevalencia de accidentes laborales en 12 meses fue del 25%. La mayoría de las lesiones se produjeron a medianoche (8,8%). Los factores asociados a los accidentes laborales fueron el exceso de horas de trabajo (OR = 3,26; IC95%: 1,26-8,41), el tabaquismo (OR = 2,72; IC95%: 1,22-6,08) y la manipulación manual (OR = 2,30; IC95%: 1,13-4,72). El uso de equipos de protección individual redujo la probabilidad de lesiones (OR = 0,42; IC95%: 0,21-0,83). Aunque la prevalencia estimada de accidentes laborales fue inferior a la de otros estudios, los resultados apuntan a acciones que deben adoptarse para reducir la carga de accidentes laborales en Etiopía. Los resultados permiten reflexionar sobre los esfuerzos de preparación y las políticas dirigidas a mejorar la seguridad y la salud de los trabajadores.

Acidentes de trabalho são preocupações de saúde pública sérias e crescentes em todo o mundo. Apesar de acidentes de trabalho serem comuns, especialmente entre trabalhadores de indústrias manufatureiras, suas crescentes complexidades não são adequadamente abordadas na literatura atual. O objetivo deste estudo foi investigar a associação de características sociodemográficas, de ambiente e comportamentais com acidentes de trabalho em trabalhadores de fábricas de grande porte na Etiópia. Um estudo transversal foi conduzido de fevereiro a abril de 2020 com 457 trabalhadores selecionados de fábricas de grande escala em Adis Abeba, capital da Etiópia. Os dados da pesquisa incluíram características sociodemográficas, condições de trabalho e segurança e fatores comportamentais como preditores de acidentes de trabalho. Ajustou-se um modelo de regressão logística para estimar a probabilidade de lesão e identificar seus fatores associados. A prevalência de 12 meses de acidentes de trabalho foi de 25%. A maioria das lesões ocorreu à meia-noite (8,8%). Os fatores associados aos acidentes de trabalho foram jornada excessiva (OR = 3,26; IC95%: 1,26-8,41), tabagismo (OR = 2,72; IC95%: 1,22-6,08) e manuseio manual (OR = 2,30; IC95%: 1,13-4,72). O uso de equipamentos de proteção individual diminuiu a chance de lesão (OR = 0,42; IC95%: 0,21-0,83). Embora nossa prevalência estimada de acidentes ocupacionais tenha sido menor em comparação com outros estudos, nossos resultados apontam para ações pendentes sobre condições modificáveis a serem tomadas para reduzir a carga de acidentes de trabalho na Etiópia. Os resultados poderão informar os esforços de preparação e políticas destinados a melhorar a segurança e a saúde dos trabalhadores.

RESUMEN

BACKGROUND: Office workers are specifically vulnerable to headache conditions. Neck pain is reported by almost 80% of patients with headaches. Associations between currently recommended tests to examine cervical musculoskeletal impairments, pressure pain sensitivity and self-reported variables in headache, are unknown. The aim of this study is to evaluate whether cervical musculoskeletal impairments and pressure pain sensitivity are associated with self-reported headache variables in office workers. METHODS: This study reports a cross-sectional analysis using baseline data of a randomized controlled trial. Office workers with headache were included in this analysis. Multivariate associations, controlled for age, sex and neck pain, between cervical musculoskeletal variables (strength, endurance, range of motion, movement control) and pressure pain threshold (PPT) over the neck and self-reported headache variables, such as frequency, intensity, and the Headache-Impact-Test-6, were examined. RESULTS: Eighty-eight office workers with a 4-week headache frequency of 4.8 (±5.1) days, a moderate average headache intensity (4.5 ± 2.1 on the NRS), and "some impact" (mean score: 53.7 ± 7.9) on the headache-impact-test-6, were included. Range of motion and PPT tested over the upper cervical spine were found to be most consistently associated with any headache variable. An adjusted R2 of 0.26 was found to explain headache intensity and the score on the Headache-Impact-Test-6 by several cervical musculoskeletal and PPT variables. DISCUSSION: Cervical musculoskeletal impairments can explain, irrespective of coexisting neck pain, only little variability of the presence of headache in office workers. Neck pain is likely a symptom of the headache condition, and not a separate entity.

RESUMEN

Purpose Neck pain is common among office workers and leads to work productivity loss. This study aimed to investigate the effect of a multi-component intervention on neck pain-related work productivity loss among Swiss office workers. Methods Office workers, aged 18-65 years, and without serious neck-related health problems were recruited from two organisations for our stepped-wedge cluster randomized controlled trial. The 12-week multi-component intervention included neck exercises, health-promotion information, and workplace ergonomics. The primary outcome of neck pain-related work productivity loss was measured using the Work Productivity and Activity Impairment Questionnaire and expressed as percentages of working time. In addition, we reported the weekly monetary value of neck pain-related work productivity loss. Data was analysed on an intention-to-treat basis using a generalized linear mixed-effects model. Results Data from 120 participants were analysed with 517 observations. At baseline, the mean age was 43.7 years (SD 9.8 years), 71.7% of participants were female (N = 86), about 80% (N = 95) reported mild to moderate neck pain, and neck pain-related work productivity loss was 12% of working time (absenteeism: 1.2%, presenteeism: 10.8%). We found an effect of our multi-component intervention on neck pain-related work productivity loss, with a marginal predicted mean reduction of 2.8 percentage points (b = -0.27; 95% CI: -0.54 to -0.001, p = 0.049). Weekly saved costs were Swiss Francs 27.40 per participant. Conclusions: Our study provides evidence for the effectiveness of a multi-component intervention to reduce neck pain-related work productivity loss with implications for employers, employees, and policy makers.Trial Registration ClinicalTrials.gov, NCT04169646.

RESUMEN

PURPOSE: The aim of this study was to investigate the effect of working from home on neck pain (NP) among office workers during the COVID-19 pandemic. METHODS: Participants from two Swiss organisations, aged 18-65 years and working from home during the lockdown (n = 69) were included. Baseline data collected in January 2020 before the lockdown (office work) were compared with follow-up data in April 2020 during lockdown (working from home). The primary outcome of NP was assessed with a measure of intensity and disability. Secondary outcomes were quality of workstation ergonomics, number of work breaks, and time spent working at the computer. Two linear mixed effects models were fitted to the data to estimate the change in NP. RESULTS: No clinically relevant change in the average NP intensity and neck disability was found between measurement time points. Each working hour at the computer increased NP intensity by 0.36 points (95% CI: 0.09 to 0.62) indicating strong evidence. No such effect was found for neck disability. Each work break taken reduced neck disability by 2.30 points (95% CI: - 4.18 to - 0.42, evidence). No such effect was found for NP intensity. There is very strong evidence that workstation ergonomics was poorer at home. CONCLUSION: The number of work breaks and hours spent at the computer seem to have a greater effect on NP than the place of work (office, at home), measurement time point (before COVID-19, during lockdown) or the workstation ergonomics. Further research should investigate the effect of social and psychological factors. TRIAL REGISTRATION: ClinicalTrials.gov, NCT04169646.

RESUMEN

PURPOSE: The COVID-19 lockdown interrupted normal daily activities, which may have led to an increase in sedentary behavior (Castelnuovo et al., 2020). The aim of this study was to investigate the effect of the COVID-19 pandemic on the level of physical activity among Swiss office workers. METHODS: Office workers from two Swiss organizations, aged 18-65 years, were included. Baseline data from January 2020 before the COVID-19 pandemic became effective in Switzerland were compared with follow-up data during the lockdown phase in April 2020. Levels of physical activity were assessed using the International Physical Activity Questionnaire. Paired sample t-tests or Wilcoxon signed-rank test were performed for statistical analysis. RESULTS: Data from 76 participants were analyzed. Fifty-four participants were female (71.1%). The mean age was 42.7 years (range from 21.8 to 62.7) at baseline. About 75% of the participants met the recommendations on minimal physical activity, both before the COVID-19 pandemic and during the lockdown. Weak statistical evidence for a decline in total physical activity in metabolic equivalent of task minutes per week (MET min/week) was found (estimate = -292, 95% CI from - ∞ to 74, p-value = 0.09), with no evidence for a decrease in the three types of activity: walking (estimate = -189, 95% CI from - ∞ to 100, p-value = 0.28), moderate-intensity activity (estimate = -200, 95% CI from - ∞ to 30, p-value = 0.22) and vigorous-intensity activity (estimate = 80, 95% CI from - ∞ to 460, p-value = 0.74). Across the three categories "high," "moderate," and "low" physical activity, 17% of the participants became less active during the lockdown while 29% became more active. CONCLUSION: The COVID-19 pandemic did not result in a reduction in total physical activity levels among a sample of Swiss office workers during the first weeks of lockdown. Improved work-life balance and working times may have contributed to this finding. CLINICAL TRIAL REGISTRATION: www.ClinicalTrials.gov, NCT04169646.

RESUMEN

BACKGROUND: Non-specific neck pain and headache are major economic and individual burden in office-workers. The aim of this study is to investigate the effect of a multi-component intervention combining workstation ergonomics, health promotion information group workshops, neck exercises, and an app to enhance intervention adherence to assess possible reductions in the economic and individual burden of prevalent and incident neck pain and headache in office workers. METHODS/DESIGN: This study is a stepped wedge cluster-randomized controlled trial. Eligible participants will be any office-worker aged 18-65 years from two Swiss organisations in the Cantons of Zurich and Aargau, working more than 25 h a week in predominantly sedentary office work and without serious health conditions of the neck. One hundred twenty voluntary participants will be assigned to 15 clusters which, at randomly selected time steps, switch from the control to the intervention group. The intervention will last 12 weeks and comprises workstation ergonomics, health promotion information group workshops, neck exercises and an adherence app. The primary outcome will be health-related productivity losses (presenteeism, absenteeism) using the Work Productivity and Activity Impairment Questionnaire. Secondary outcomes are neck disability and pain (measured by the Neck Disability Index, and muscle strength and endurance measures), headache (measured by the short-form headache impact test), psychosocial outcomes (e.g. job-stress index, Fear-Avoidance Beliefs Questionnaire), workplace outcomes (e.g. workstation ergonomics), adherence to intervention, and additional measures (e.g. care-seeking). Measurements will take place at baseline, 4 months, 8 months, and 12 months after commencement. Data will be analysed on an intention to treat basis and per protocol. Primary and secondary outcomes will be examined using linear mixed-effects models. DISCUSSION: To the authors' knowledge, this study is the first that investigates the impact of a multi-component intervention combining current evidence of effective interventions with an adherence app to assess the potential benefits on productivity, prevalent and incident neck pain, and headache. The outcomes will impact the individual, their workplace, as well as private and public policy by offering evidence for treatment and prevention of neck pain and headache in office-workers.
