Enhancing Nutritional Status and Addressing Micronutrient Deficiencies: Evaluating the Impact of Workplace Nutrition Program on Female Workers in Vietnam

This randomized controlled clinical study aimed to assess the effectiveness of a nutrition intervention program for non-pregnant female workers in Vietnam. A total of 500 female workers were randomly assigned to the intervention and control groups. Participants in the intervention group were provided nutrition education, personalized specific dietary, and received oral nutrition supplements (ONS)-which contained multi-minerals and vitamins according to recommendations for adults for a duration of 12 wk, while participants in the control group received only nutrition education. The result shows the percentage of malnutrition by BMI in the control group rose from 15.6% to 21.3% after 12 wk; the figure for counterpart experienced a remain unchanged (p<0.05). Additionally, the mean of serum zinc in the intervention group significantly increased from 49.0±21.2 μg/dL to 53.6±19.5 μg/dL after 12 wk. Moreover, the intervention group demonstrated significant increases in serum iron and total serum calcium levels (p<0.05), with from 13.9±5.6 μmol/L to 15.3±5.8 μmol/L, and from 2.36±0.15 mmol/L to 2.4±0.09 mmol/L, respectively. The participants of the intervention group were more likely to have higher total serum calcium (Coef=0.04, p<0.05), serum iron (Coef=1.99, p<0.05), and serum zinc (Coef=18.9, p<0.05), which presents a reduce micronutrient deficiency. In conclusion, workplace nutrition interventions effectively mitigate micronutrient deficiencies and improve the nutritional status of female workers.

Breast Cancer Incidence among Female Workers by Different Occupations and Industries: A Longitudinal Population-Based Matched Case-Control Study in Taiwan

BACKGROUND

Breast cancer is the leading cause of cancer incidence worldwide and in Taiwan. The relationship between breast cancer and occupational types remains unclear. This study aimed to investigate lifetime breast cancer incidence by different occupational industries among female workers in Taiwan.

METHODS

A population-based retrospective case-control study was conducted using three nationwide population-based databases. Matched case and control groups were identified with 1-to-4 exact matching among 103,047 female workers with breast cancer diagnosed in 2008-2017 and those without breast cancer. Their lifetime labor enrollment records were tracked using the National Labor Insurance Database, 1950-2017. Conditional logistic regression was used to analyze the association between types of occupational industries and risk of incident breast cancer.

RESULTS

Our study found slightly significant breast cancer risk among the following major occupational classifications: manufacturing (OR: 1.027, 95% CI: 1.011-1.043); wholesale and retail trade (OR: 1.068, 95% CI: 1.052-1.084); information and communication (OR: 1.074, 95% CI: 1.043-1.105); financial and insurance activities (OR: 1.109, 95% CI: 1.086-1.133); real estate activities (OR: 1.050, 95% CI: 1.016-1.085); professional, scientific, and technical activities (OR: 1.118, 95% CI: 1.091-1.145); public administration, defense, and social security (OR: 1.054, 95% CI: 1.023-1.087), education (OR: 1.199, 95% CI: 1.168-1.230); and human health and social work activities (OR: 1.125, 95% CI: 1.096-1.156).

CONCLUSIONS

Greater percentages of industrial occupations (i.e., manufacturing, wholesale and retail, or health professionals) were associated with slightly increased breast cancer risk. Further studies should investigate the possible risk factors among female workers in those industries with slightly higher incidence of breast cancer.

COVID-19's impacts on business activities and female workers: Empirical evidence from global developing economies

This paper empirically examines the economic impacts of COVID-19 on firms' business activities and female workers in 10 developing economies around the world. Based on a survey conducted by the World Bank, we constructed a firm-level panel dataset and investigated how firms' production and finances have developed during COVID-19. We also investigated female workers' employment situations and how they were affected by firm performance. COVID-19 indeed casted seriously adverse impacts in the developing world. As time passes, firms' production has been recovering, but their finances are worsening, and the female workers are facing worse situations in forms of higher probabilities of losing jobs and getting furloughed. Other variables such as workforce, capacity utilisation, and exports also play important roles in this process.

Football and Zumba Training in Female Hospital Staff: Effects after 12 and 40 Weeks on Self-Reported Health Status, Emotional Wellbeing, General Self-Efficacy and Sleep Problems

Background: This 40-weeks intervention study evaluates the effects on self-reported health status, emotional wellbeing, general self-efficacy and sleep problems among female hospital employees. Methods: 107 employees were cluster-randomized into three groups; football (FG), Zumba (ZG) and control (CG). Outcome measurements were conducted at baseline, 12 and 40 weeks. Weekly training frequencies in the first 12 and next 28 weeks were 2.4 ± 0.3 and 0.8 ± 0.2 in FG and 2.3 ± 0.3 and 0.9 ± 0.2 in ZG. Results: Compared to the CG, the ZG showed significant improvement in self-reported health status (p = 0.025), a reduced frequency of poor and restless sleep (on a 0–4 scale) (p = 0.004), as well as a tendency for reduction in the frequency of problems falling asleep (p = 0.055) and overall sleep problems (p = 0.051). Between baseline and 12 weeks, both the FG (p = 0.017) and the ZG (p = 0.017) showed within-group improvements in emotional wellbeing, whereas this improvement was maintained only in the ZG between baseline and 40 weeks (p = 0.002). The FG showed a significant within-group improvement in general self-efficacy (p = 0.012) between baseline and 12 weeks follow-up, with no such improvements in the other groups. Conclusion: The present findings revealed that a physical activity intervention with Zumba as well as football training may improve mental health and sleep outcomes in female hospital staff.

Effect of family stress on life satisfaction among female workers during the COVID-19 epidemic in China: Exploring the roles of anxiety symptoms and age

The study aimed to investigate the level of life satisfaction (LS) among Chinese female workers after resuming work during the COVID-19 epidemic, and to further explore the potential mediating and moderating roles in the association between family stress and LS. Self-reported questionnaires were completed by 10,175 participants. Results showed that the level of LS decreased. The family stress had a negative effect on LS, and the effect was mediated by anxiety symptoms. Additionally, age moderated the direct and indirect effects within this relationship. Interventions aiming to improve LS should consider these aspects and younger workers should be given special attention.

The association between health status and job satisfaction among female workers: A nationwide cross-sectional study

The purpose of this study was to determine the job satisfaction among female workers in Korea and the association between health status and job satisfaction. The Korean Longitudinal Survey of Women and Families was used for this nationwide cross-sectional study. Data from 1570 female workers were analyzed to determine job satisfaction and examine the association between health status and job satisfaction, controlling for other variables such as personal characteristics, work attributes, job opportunities, and work conditions. Analyses included descriptive statistics, independent t-tests, ANOVA, Pearson's correlation, and multivariate regression. Subjective health status was positively related, while diagnosed disease and depressive symptoms were negatively associated with job satisfaction. Monthly salary, work hours, fringe benefits, and geographical region were also significantly related to female workers' job satisfaction, and commute distance was related to job satisfaction with a small effect size. This study thus found that subjective health status, diagnosed disease, and depressive symptoms were related to female workers' job satisfaction. Health promotion and supporting mental health among female workers may be important managerial strategies for supporting increased job satisfaction in female workers.

Working Conditions and Urinalysis Dipstick Testing among Female Rice Farmers: A Preliminary Cross-Sectional Study

This cross-sectional study aimed to assess working conditions and renal function among female rice farmers in Nan Province, Thailand. Purposive random sampling was used to select participants who met the inclusion criteria. Data were collected from 65 female rice farmers using in-depth interviews. A walk-through survey was performed to examine hazards in the rice farm and a dipstick test was used for urinalysis. The results demonstrated that all rice farming stages contained risks from physical, chemical, biological and ergonomic hazards and that no measures had been implemented to protect participants' health from these risks. The screening test results showed low urinary pH (5-6) in 54 women (83.0%), but high urinary specific gravity (1.030) in 25 women (38.5%). Participants' urine contained leukocytes in 15 women (23.1%), protein in 14 women (21.5%) and blood in 13 women (20%). This study results suggest that farming activities affect female rice farmers' health and safety. Urinalysis dipstick tests, which can be administered at the local public health promoting hospital, should be used to assess the occupational health status. The results will be useful for health surveillance and follow-up of the participants. These preliminary findings need to be confirmed in a larger study including non-farmers.

Development and psychometric properties of the attitude scale towards female workers in the healthcare settings

AIM

The aim of this study was to develop a new instrument to evaluate healthcare professionals' attitudes towards female workers in the healthcare settings-the Attitude Scale Towards Female Workers (ASTFW)-and test its psychometric properties.

DESIGN

This is a scale development study.

METHOD

A three-phase structure was used: (1) creating the item pool, (2) preliminarily evaluating items and (3) refining the scale and evaluating psychometric properties. The scale's content validity, construct validity, internal consistency and temporal stability were evaluated according to the scale development guidelines. The scale's psychometric properties were tested with 1,635 healthcare professionals working in six different hospitals. The data were collected between November 2018 and July 2019.

RESULTS

The scale items were obtained from face-to-face, semi-structured, in-depth individual interviews with the healthcare professionals. The scale's content validity index was 0.96. According to exploratory factor analysis, the scale consisted of 30 items and five subdimensions; the subdimensions were found to explain 54.48% of the total variance. Fit indices obtained with confirmatory factor analysis were at acceptable and good levels. The scale was found to have high internal consistency and temporal stability.

CONCLUSION

The ASTFW is a psychometrically valid and reliable measurement instrument. The 30-item scale consists of five subdimensions: performance, gender roles, recruitment and retention, career, and emotionality. Impact This scale, which has good psychometric properties, can be used to perform a multidimensional evaluation of the attitudes of healthcare professionals in healthcare workplaces towards female workers. This scale can be useful in shedding light on negative attitudes towards female healthcare professionals in the health sector.

Revisiting the Women Workplace Culture Scale: Validation and Psychometric Properties of a Three-Factor Structure in an Iranian Study Sample

This paper describes the validation process of the Persian version of the Women Workplace Culture Scale and provides information about the perception of this culture in an Iranian working environment. A 30-item Persian version of the Women Workplace Culture (WWC) Questionnaire was administered to women working in public departments of the city of Bojnord, Iran (N = 200). As a result of a theory- and data-driven bottom-up empirical approach, a reduced 10-item three-dimensional scale was achieved entailing (I) perceived societal barriers for career development, (II) perceived organizational barriers, and (III) sexual harassment. This parsimonious solution showed satisfactory values of reliability, factorial validity and convergent-discriminant validity analysis based on correlations with the unidimensional 10-item Perceived Stress Scale and the 12-item Career Success Questionnaire. The scale can be used to measure women workplace culture in Iran and other Persian-speaking, Islamic-Arabic countries. It can also constitute a starting point for organizational diagnosis in projects aimed to enhance working women’s occupational health and societal participation.

Association between Occupational Characteristics and Overweight and Obesity among Working Korean Women: The 2010-2015 Korea National Health and Nutrition Examination Survey

Associations between several occupational characteristics and obesity are not fully elucidated in Korean working populations, especially in females. This study investigated associations between occupational characteristics and overweight/obesity among Korean women. Data on 2090 female workers (the mean age was 38.8 ± 0.2 years), extracted from Korean National Health and Nutrition Examination Surveys in 2010-2015, were analyzed and showed that 6.8% of subjects were underweight, 50.8% had normal weight, 20.1% were overweight, and 22.2% were individuals with obesity. Multiple regression analysis was performed to examine associations between occupational characteristics and overweight/obesity, after controlling for demographic, behavioral, and health-related characteristics. The reference group was normal weight. Working hours were strongly associated with overweight/obesity. The odds ratio (OR) of obesity in women who worked for ≥60 hours per week was 2.68 (95% confidence interval: [CI] 2.13-3.36) compared with those who worked for <40 hours. Night/shift workers were 1.21 times (95% confidence interval: [CI] 1.01-1.45) more likely to experience obesity than day or evening workers. In conclusion, obesity rates increase among female workers with longer working hours and those who work at night or in shifts. Occupational characteristics should be considered in the prevention of obesity among working women.

Improving Workplace-Based Intervention in Indonesia to Prevent and Control Anemia

Purpose: The present study determined female workers' experiences and preferences to improve the workplace anemia prevention program in Indonesia by studying their perception of anemia, as well as its risk factors and control. Methods: This qualitative study was conducted using focus group discussions (FGDs) to assess female workers' understanding about anemia and possible improvements for workplace-based intervention in a factory located in East Jakarta, Indonesia. Participants were consisted of 14 FGD groups according to anemia status and potential affecting characteristics, including marital status, ethnicity, religion, and frequency of medical consultations. A semistructured questionnaire was used to determine participants' ideas and experiences of anemia control. Results: A total of 14 FGDs were conducted including 105 female workers who participated in this study. More than half of the participants showed a good understanding of the signs and symptoms of anemia. They expected the company to improve the factory health service by improving accessibility and affordability of food and controlling hazardous substances considered risk factors of anemia in the workplace. Conclusion: Female workers have valuable experience and ideas that should be considered to improve workplace-based anemia intervention. They proposed improvement of workplace-based health services such as improving factory canteen and clinics services and controlling potential anemia risk hazards in the workplace.

Effectiveness of Workplace Nutrition Programs on Anemia Status among Female Readymade Garment Workers in Bangladesh: A Program Evaluation

Eight in ten female readymade garment (RMG) workers in Bangladesh suffer from anemia, a condition which damages both health and productivity. This study evaluated the effectiveness of a workplace nutrition program on anemia reduction in female RMG workers of Bangladesh. A quasi-experimental mixed method study was conducted on 1310 non-pregnant female RMG workers from four factories. Two types of intervention packages (A and C) were tested against their respective controls (B and D) over a 10-month period. Among factories that already provided lunch to workers with regular behavior change counseling (BCC), one intervention (A) and one control (B) factory were selected, and among factories that did not provide lunches to their workers but provided regular BCC, one intervention (C) and one control (D) factory were selected: (A) Lunch meal intervention package: daily nutritionally-enhanced (with fortified rice) hot lunch, once weekly iron-folic acid (IFA) supplement and monthly enhanced (with nutrition module) behavior change counseling (BCC) versus (B) Lunch meal control package: regular lunch and BCC; and (C) Non-meal intervention package: twice-weekly IFA and enhanced BCC versus (D) Non-meal control package: BCC alone. Body weight and capillary hemoglobin were measured. Changes in anemia prevalence were estimated by difference-in-difference (DID) method. Thematic analysis of qualitative in-depth interviews with RMG workers was performed and findings were triangulated. Anemia was reduced significantly in both lunch meal and non-meal intervention (A and C) group (DID: 32 and 12 percentage points, p: <0.001 and <0.05 respectively). The mean hemoglobin concentration also significantly increased by 1 gm/dL and 0.4 gm/dL in both A and C group (p: <0.001 respectively). Weight did not change in the intervention groups (A and C) but significantly increased by more than 1.5 kg in the comparison groups (B and D). The knowledge of different vitamin and mineral containing foods and their benefits was increased significantly among all participants. Workplace nutrition programs can reduce anemia in female RMG workers, with the greatest benefits observed when both nutritionally enhanced lunches and IFA supplements are provided.

Effort-reward imbalance and ambulatory blood pressure among female Las Vegas hotel room cleaners

BACKGROUND

Effort-reward imbalance (ERI) was hypothesized to be associated with ambulatory blood pressure (ABP) and pulse pressure (PP) among female hotel room cleaners.

METHODS

ERI, ABP, and PP were assessed among 419 cleaners from five hotels during 18 waking hours. Adjusted linear regression models were used to assess associations of ERI with ABP and PP during 18-hours, work hours, and after work hours.

RESULTS

There was a pattern of higher ERI being associated with higher 18-hour systolic ABP and 18-hour PP although the results were imprecise. An increase of ERI by half its range was associated with a 1.6 mmHg (95% CI, -1.6-4.7) increase in 18-hour systolic blood pressure (SBP) and a 0.7 mmHg (95% CI, -1.1-2.5) increase in 18-hour PP. An increase in rewards by half its range was associated with a 2 mmHg decrease in after-hours SBP (-2.2, 95% CI, -5.4-1.0) and after-hours PP (-1.9, 95% CI, -3.8-0.0). Among females 45 years or older, ERI was associated with 2.1 and 2.2 mmHg increase in 18-hour and work hours diastolic ABP, respectively, compared to a 0 mmHg change in 18-hour and work hours diastolic ABP in younger women. The number of dependents at home attenuated the association.

CONCLUSIONS

ERI was positively associated with ABP, particularly SBP, and the association was modified by age and the number dependents at home, although the estimates were imprecise. Workplace interventions that integrate stress management and active ABP surveillance appear warranted. However, larger studies with Latina women need to confirm our results.

Occupational violence among female workers in an Iranian industrial area

Few studies have examined violence against female workers in the industrial sector. This study explored the prevalence of various types of violence and associated factors among female workers in the industrial sector. This descriptive survey was conducted in eleven industrial sites in Kashan, Iran, from April through September 2014. We used a 78-item questionnaire to obtain data from 817 female workers. More than half of the participants reported having experienced at least one type of violence. The prevalence rates of verbal aggression, sexual harassment, and physical violence were 52.5%, 12% and 11.5%, respectively. Single female workers (adjusted odds ratio [AOR] = 2.06, 95% CI = 1.09-4.27), and age older than 35 years were (AOR = 2.37, 95% CI = 1.26-2.93) each significantly related to increased odds of verbal violence. Short duration of employment (≤ five years) was the most strongly associated factor for sexual harassment (AOR = 2.82, 95% CI = 1.7-2.94). Working the night shift was significantly associated with encountering verbal violence (AOR = 2.79, 95% CI = 1.69-3.06). The high prevalence of violence suggests that management in industrial workplaces should invest time and resources in addressing violence. Developing a reporting procedure and training programs are recommended in dealing with workplace violence risk.

Job strain associated with increases in ambulatory blood and pulse pressure during and after work hours among female hotel room cleaners

BACKGROUND

Previously documented elevated hypertension rates among Las Vegas hotel room cleaners are hypothesized to be associated with job strain.

METHODS

Job strain was assessed by questionnaire. Ambulatory blood pressure (ABP) was recorded among 419 female cleaners from five hotels during 18 waking hours. Multiple linear regression models assessed associations of job strain with ABP and pulse pressure for 18-h, work hours, and after work hours.

RESULTS

Higher job strain was associated with increased 18-h systolic ABP, after work hours systolic ABP, and ambulatory pulse pressure. Dependents at home but not social support at work attenuated effects. Among hypertensive workers, job strain effects were partially buffered by anti-hypertensive medication.

CONCLUSIONS

High job strain is positively associated with blood pressure among female hotel workers suggesting potential for primary prevention at work. Work organizational changes, stress management, and active ABP surveillance and hypertension management should be considered for integrated intervention programs.

Returning to Work after Childbirth in Europe: Well-Being, Work-Life Balance, and the Interplay of Supervisor Support

Parents returning to work after the arrival of a new son or daughter is an important question for understanding the trajectory of people's lives and professional careers amid current debates about gender equality and work-life balance (WLB). Interestingly, current research concludes that general WLB practices at the workplace may be necessary in the specific case of women returning to work after childbirth because of the particular maternal and infant factors involved. However, WLB practices as a flexible arrangement may work against women because they may be viewed as a lack of organizational commitment. Therefore, research on this topic could benefit from considering supervisor support as a complement of such practices, but previous research has analyzed WLB and supervisor support separately and scarcely. To fill this gap in the literature, we use two sub-samples of 664 female employees and 749 male employees with children under the age of one from 27 European countries participating in the 6th European Working Conditions Survey (EWCS-2015) to study the impact of perceived WLB on European women's perceived well-being after childbirth, in contrast with previous literature. We also analyze the impact of perceived supervisor support (SS) and its interaction with perceived WLB on women's well-being after childbirth, and explore differences with men after childbirth, a collective underexplored by the literature. We find significant gender differences on the relative impact of WLB, SS, and their interaction on perceived job well-being. Our results have important implications for human resource practices in organizations. In particular, they suggest that gendered WLB practices should be encouraged, and stress the relevance of the human factor over human resource practices in addressing the difficulties that women returning to work face after childbirth.

Prevalence of carpal tunnel syndrome and its correlation with pain amongst female hairdressers

OBJECTIVES

Carpal tunnel syndrome (CTS) may develop with repetitive and forced movements of the hands and wrists. In this study, we have aimed to evaluate whether the frequency of CTS is increased amongst female hairdressers as compared with unemployed women or not. Besides, we have also analyzed whether the functionality and pain intensity levels amongst female hairdressers with CTS are different from the ones of unemployed women with CTS or not.

MATERIAL AND METHODS

The consecutive female hairdressers and unemployed women who had referred to our electroneuromyography (ENMG) laboratory for the upper extremity nerve conduction studies were included. They were evaluated in terms of clinical and ENMG findings, socio-demographic characteristics, functionality and pain intensity levels determined with the Boston CTS Questionnaire and visual analog scale (VAS).

RESULTS

In this study, 110 women (70 female hairdressers and 40 unemployed women) were included. The frequency of CTS among hairdressers (74.3%) was higher than the one of the unemployed control group (55%) (p = 0.032). We detected that as the time period of occupation in hairdressing increased, the risk of developing CTS also increased among hairdressers (p < 0.001). Additionally, pain intensity and functional loss levels were higher for hairdressers with CTS than those for the control group with CTS (p = 0.005, p < 0.001, p = 0.028, respectively).

CONCLUSIONS

The frequency of CTS is elevated for female hairdressers with respect to the unemployed women as in many other occupations requiring forced or repetitive hand movements. Besides, the occupational exposure in hairdressing also results in more elevated pain intensity and functional loss levels related with CTS as compared with the unemployed subjects.

Work, gender roles, and health: neglected mental health issues among female workers in the ready-made garment industry in Bangladesh

BACKGROUND

Traditionally, women in Bangladesh stayed at home in their role as daughter, wife, or mother. In the 1980s, economic reforms created a job market for poor, uneducated rural women in the ready-made garment industry, mostly located in urban areas. This increased participation in paid work has changed the gender roles of these women. Women's earnings support their family, but they are also separated from their children, with impacts on their mental health and well-being. This study explores the lived experience of women in Bangladesh working in the ready-made garment industry as they strive to be mothers and family providers, often in high-stress conditions.

METHODS

The study was conducted in two industrial areas of Dhaka over 8 months. Data collection included a literature review, 20 in-depth interviews with married female garment workers, and 14 key-informant interviews with officials from the Ministry of Labour and Employment, health-service providers within the garment factories, factory managers, and representatives of the Bangladesh Garment Manufacturers and Exporters Association. The data collected were analyzed thematically.

RESULTS

Poverty was a key motivating factor for female migrant workers to move from rural areas. Their children stay in their village with their grandparents, because of their mothers' work conditions and the lack of childcare. The women reported stress, anxiety, restlessness, and thoughts of suicide, due to the double burden of work and separation from their children and family support. Further, they cannot easily access government hospital services due to their long work hours, and the limited medical services provided in the workplace do not meet their needs.

CONCLUSION

In order to improve the health and well-being of female garment workers, steps should be taken to develop health interventions to meet the needs of this important group of workers who are contributing significantly to the economic development of the country.

Housing for Female Factory Workers: The Association between Renting Accommodation and Satisfaction with Income and Living Conditions

Background

Vietnam has experienced a strong wave of migrants to urban and industrialized areas. This is a challenge for both local and national governments, which need to address the problems of the poor and socially marginalized, including providing housing for rural-to-urban migrants. Poor housing and the economic burden of house renting are increasingly recognized as determinants of both physical and mental health.

Objectives

This paper examined the association between renting accommodation and income satisfaction and living conditions of female workers in light manufacturing industries in Vietnam.

Methods

A cross-sectional study was implemented with quantitative survey of 2,818 female workers in 10 light manufacturing factories in 3 industrial zones by a self-administered questionnaire.

Results

Over 38% of female workers had to rent accommodation. The average expense for accommodation, water and electricity accounted for 30.1% of renters' income, which is 7.2% (CI 95%, 5.3–9.3%) higher than for non-renters. A higher proportion of renters than non-renters considered their income was unstable and insufficient for living costs. In addition, only 7.2% of renters reported that their living conditions were suitable, notably lower than non-renters (22.4%).

Conclusion

The study showed the economic burden of renting accommodation on workers' income satisfaction and living conditions. The findings have implications for an adequate housing access strategy for workers including the integration of housing development in the planning and development of industrial zones and factories.

Roles of age, length of service and job in work-related injury: a prospective study of 63,620 person-years in female workers

BACKGROUND

The roles of age, length of service and job in various work-related injury types are unknown and deserve investigations among female workers. This study assessed their roles in the occurrence of injury.

METHODS

Three-year prospective study of all 22,952 permanently employed women at the French national railway company: 63,620 person-years, 756 injuries with working days lost, coded using the company's injury classification derived from that of the French health insurance scheme. We investigated the incidence of four types of injury: fall on same level, fall to lower level, materials/equipment/objects handling, and other injuries. Data were analyzed using negative binomial regression.

RESULTS

Workers aged <25 were subject to a higher risk for all types of injuries. Older workers (45-55 years) were subject to a higher injury risk for fall on same level and fall to lower level. For fall on same level as for fall to lower level the relative risk decreased steadily with increasing length of service with the company, from 1.60 for 1 year to 0.50-0.60 for ≥30 years. For injuries due to materials/equipment/objects handling the relative risk decreased from 1.05 for one year to 0.49 for 5-9 years, and then increased to about 1.50 for 20-29 years and ≥30 years.

CONCLUSIONS

Younger and shorter lengths of service were at risk for various types of injuries. Higher length of service was at risk for injury due to materials/equipment/objects handling. Preventive measures should consider the respective risks associated with age, years of employment and job.
