ABSTRACT
Introducción Las cifras migratorias sitúan a Chile como uno de los países sudamericanos con mayor número de migrantes. El presente estudio estimó la relación entre características sociodemográficas, calidad de vida y riesgos psicosociales laborales en migrantes trabajadores de la región del Maule. Métodos Estudio transversal con trabajadores migrantes entre 18 y 60 años, residentes en la Región del Maule (n = 145). Las encuestas aplicadas fueron: Cuestionario de riesgo psicosocial, Cuestionario de salud y calidad de vida y Cuestionario sociodemográfico. Se realizó un análisis estadístico bivariado con pruebas no paramétricas de U de Mann Whitney, Kruskal Wallis, correlación de Spearman y modelos de regresión lineal múltiple. Resultados Un 21% de los migrantes mantuvo en Chile la misma actividad laboral a la que se dedicaban en su país de origen. Si bien la calidad de vida de la salud física y mental es adecuada, 52% presenta bajas demandas psicológicas en el trabajo, 48,9% bajos niveles de trabajo activo y habilidades de desarrollo, 57,7% tiene un nivel de alto riesgo en la compensación y la autoestima, y 65,5% un nivel de alto riesgo de doble presencia en el trabajo. Los migrantes con mayor calidad de vida en la dimensión salud física presentan menor riesgo de mantener el equilibrio entre el esfuerzo y recompensa, poseen un trabajo de 44 horas a la semana y no llegaron a trabajar directamente al Maule. Los migrantes con mayor calidad de vida en la dimensión salud mental poseen menor riesgo en las demandas emocionales, perciben mayor apoyo social en la empresa y menor preocupación por las tareas domésticas. Conclusiones Los migrantes con menor calidad de vida en la dimensión salud física, presentan menores compensaciones en el trabajo, bajo reconocimiento, llegaron directamente a trabajar a la región y poseían trabajos con menos horas de contrato. Los trabajadores con menor calidad de vida en su salud mental exhiben mayor riesgo en las exigencias psicológicas en el trabajo, perciben bajo apoyo social en la empresa y preocupación por responder al trabajo doméstico y al asalariado.
Introduction Migration figures place Chile as one of the South American countries with the highest rate of migrants. The present study estimated the relationship between sociodemographic characteristics, quality of life, and psychosocial occupational risks in migrant workers from the Maule region. Methods Cross-sectional study with migrant workers between 18 and 60 years of age residing in the Maule region (n = 145). The applied questionnaires were: a psychosocial risk questionnaire, a health and quality of life questionnaire, and a sociodemographic questionnaire. A bivariate statistical analysis was performed using nonparametric Mann-Whitney U tests, Kruskal Wallis, Spearman correlation, and multiple linear regression models. Results In Chile, 21% of the migrants maintained the same work activity as in their country of origin. Although the quality of life in physical and mental health is adequate, 52% have low psychological demands at work, 48.9% have low levels of active work and development skills, 57.7% have a high-risk level of compensation and self-esteem, and 65.5% have a high-risk level of double presence at work. Migrants with a higher quality of life in the physical health dimension have a lower risk of maintaining a balance between effort and reward; they worked 44 hours a week and did not work directly at Maule. Migrants with a higher quality of life in the mental health dimension have a lower risk of emotional demands, perceive greater social support in the company, and are less concerned about domestic chores. Conclusions Migrants with lower quality of life in the physical health dimension presented less compensation at work and recognition, came to work directly in the region, and had jobs with fewer contract hours. Workers with lower quality of life in their mental health exhibited a greater risk of psychological demands at work and perceived low social support in the company; they were concerned about having to respond to domestic and salaried work.
ABSTRACT
Objective To understand the health-related quality of life (HRQOL) of migrant workers with pneumoconiosis who received basic medical treatment in Hunan Province. Methods A total of 613 migrant workers with pneumoconiosis who received basic medical treatment and assistance in Hunan Province was selected as the study subjects using stratified random sampling method. The European Quality of Life-5 Dimensions (EQ-5D) questionnaire was used to assess their HRQOL. Results The abnormality of the five dimensions of the EQ-5D health description system, from high to low, were as follows： daily activities, mobility, pain/discomfort, anxiety/depression, and self-care, with the abnormal rates of 50.9%, 46.8%, 41.1%, 21.0%, and 14.5%, respectively. The visual analogue scale (VAS) score of EQ-5D was (63.5±18.6) points. Patients with stage Ⅲ pneumoconiosis had high abnormality in mobility, daily activities, and pain/discomfort compared with those with stage Ⅰ and Ⅱ disease (all P<0.02). Patients in stage Ⅱ and Ⅲ of pneumoconiosis had higher incidence of anxiety/depression compared with those with stage I disease (all P<0.02). Patients with complications in addition to pneumoconiosis had higher abnormality in mobility, self-care, and pain/discomfort compared to those with simple pneumoconiosis or those eligible for lung lavage treatment (all P<0.02). Patients with simple pneumoconiosis had a higher incidence of anxiety/depression compared with those eligible for lung lavage treatment (P<0.02). Patients with stage Ⅲ pneumoconiosis had lower average VAS scores compared with stage Ⅰ and Ⅱ patients (all P<0.02). Patients with simple pneumoconiosis or those with complications had lower average VAS scores compared with those eligible for lung lavage treatment (all P<0.05). Conclusion The HRQOL of pneumoconiosis patients among migrant workers needs improvement, especially for patients with stage Ⅲ disease and those with complications. This study indicates the need of optimizing policies, raising the hospitalization expense limit for critically ill patients with stage Ⅲ pneumoconiosis or with complications, and improving their HRQOL.
ABSTRACT
Objective: To investigate and understand the medical security and quality of life of migrant workers with pneumoconiosis, so as to provide scientific basis for the prevention and control countermeasures of migrant workers with pneumoconiosis and targeted poverty alleviation. Methods: Using a stratified random sampling method, 200 migrant workers diagnosed with pneumoconiosis at the Shandong Academy of Occupational Health and Occupational Medicine from January 2016 to December 2021 were selected as the observation group, while 200 non migrant workers diagnosed with pneumoconiosis were selected as the control group. St. George's Respiratory Questionnaire (SGRQ) and Pneumoconiosis Questionnaire were used to collect and compare information on the age, working age of dust exposure, economic sources, employment status, income, medical security and quality of life of two groups of patients. Results: The age of migrant worker pneumoconiosis patients in the observation group was (58.1±8.1) years old, and the working age of dust exposure was (19.3±10.1) years. The main source of income was children support (85.5%, 171/200), employment status was mainly wait for employment or unemployed (69.0%, 138/200), personal monthly income was mainly non income (90.0%, 180/200), and family annual income was mainly less than 10000 yuan (48.0%, 96/200). The average personal annual medical expenditure of 5000-<10000 yuan accounted for 42.0% (84/200). The age of pneumoconiosis patients in the control group was (59.2±8.9) years old, and the working age of dust exposure was (20.2±10.5) years. The main source of income was retirement pension or salary (99.0%, 198/200), with retirement as the main employment status (66.0%, 132/200), the main personal monthly income was 2000-<4000 yuan (61.5%, 123/200), the main family annual income was 20000-<40000 yuan (44.0%, 88/200), and the average personal annual medical expenditure was mostly non-expenditure (92.0%, 184/200). There were statistically significant differences in the distribution of economic sources, employment status, personal monthly income, family annual income and average personal annual medical expenditure between the two groups (P<0.001). The main type of insurance for the observation group was rural cooperative medical care (68.5%, 137/200), and 87.0% (174/200) had no medical reimbursement and a proportion less than 50%. There were statistically significant differences in insurance type and medical reimbursement proportion between the two groups (P<0.001). The respiratory symptoms, activity ability, daily life influence and total quality of life scores of pneumoconiosis patients in the observation group were significantly higher than those in the control group, the differences were statistically significant (P<0.001) . Conclusion: Migrant workers with pneumoconiosis have low income, high medical expenditure, low medical reimbursement proportion and poor quality of life. Therefore, it is necessary to draw high attention from relevant departments and provide timely attention and assistance to improve the quality of life of migrant workers with pneumoconiosis.

Purpose The number of Vietnamese technical intern trainees is increasing annually due to the revision of the Immigration Control Law in Japan. However, there are few studies focusing on the trainees’ health issues and medical consultations. This study aims to clarify the difficulties they face in obtaining healthcare services after coming to Japan.Method Semi-structured interviews regarding the difficulties faced by trainees in accessing medical services were conducted. Twelve Vietnamese technical intern trainees (eight men [66.6%] and four women [33.4%] with an average age of 26.3 years and average stay period of 2 years and 3 months) living in the Kansai area were interviewed. Data analysis was conducted using a qualitative descriptive method.Results and Discussion Four categories of difficulties in receiving medical treatment were found: “no hospital visits unless the situation worsens,” “inability to receive medical services without the support of company or supervising organization officials,” “inability to seek confirmation even if they have questions or are dissatisfied,” and “hesitation for seeking medical help due to work and scheduling.” For Vietnamese technical intern trainees, the company or supervising organization officials’ support played an important role in accessing medical services. Moreover, even if the trainees had doubts or dissatisfactions, they were unable to ask questions and receive confirmation. Therefore, it is necessary not only to actively explain the need for medical services to the company or supervising organization officials but also to ask the trainees if they have any doubts.Conclusion The company and supervising organization official’s support played an important role at accessing medical service. It will be essential to cooperate not only with them but also with the occupational health field and regional medical institutions.
ABSTRACT
ABSTRACT: Based on the data of "employment and food demand of urban migrant workers", this paper empirically analyzed the impact of urban pension insurance on the nutritional intake structure of migrant workers. The results showed that participating in urban pension insurance can change the nutritional intake structure of migrant workers. Additionally, fat and protein replace carbohydrate as the main nutrition sources for migrant workers. After controlling the income and labor intensity of migrant workers and other factors, urban pension insurance has a positive effect on the intake of fat and protein of migrant workers for they increase by 13.5% and 8.8% respectively. There is no significant effect on the intake of carbohydrates of migrant workers. The calorie intake of migrant workers increases by 6.8% accounting for the change of nutritional intake structure. Endogenous and robustness tests showed that the above conclusions are robust. Heterogeneity analysis showed that there is no significant difference in the effect of urban pension insurance on calorie intake of migrant workers in different income levels and age groups.
RESUMO: Este artigo usa os dados da pesquisa de "Emprego e demanda alimentar dos trabalhadores migrantes urbanos" para analisar empiricamente o impacto do seguro patrimonial urbano na estrutura de ingestão nutricional dos trabalhadores migrantes. O estudo constatou que: o seguro-pensão urbano mudou a estrutura de ingestão nutricional dos trabalhadores migrantes. Gordura e proteína substituíram os carboidratos e se tornaram a principal fonte de nutrição dos trabalhadores migrantes. Depois de controlar fatores como a renda e a intensidade do trabalho dos trabalhadores migrantes, o seguro de pensão urbana aumentou significativamente a ingestão de gordura e proteína dos trabalhadores migrantes em 13,5% e 8,8%, respectivamente, enquanto a ingestão de carboidratos dos trabalhadores migrantes não foi afetada. Significativamente afetado. A transformação da estrutura de ingestão nutricional dos trabalhadores migrantes aumentou sua ingestão calórica em 6,8%. Os testes de endogenia e robustez mostram que as conclusões acima são robustas. A análise de heterogeneidade mostra que não há diferença significativa no efeito do seguro previdenciário urbano sobre o aumento da ingestão de calorias para trabalhadores migrantes de diferentes níveis de renda e diferentes grupos etários.
ABSTRACT
Objective:To understand the health self-assessment and related influencing factors in the migrant workers who received of physical examination in Shanghai， so as to provide reference for formulating health service policies for migrant workers. Methods:Taking Shanghai "Intelligent Blue Collar" Health Science Popularization Service Station as the investigation site， 8，100 urban workers were surveyed by questionnaire. The questionnaire includes basic information， health self-assessment， basic medical insurance coverage and satisfaction， subjective well-being and so on. Results:There were significant differences between migrant workers and local workers in health self-assessment， two-week disease prevalence rate， and chronic disease prevalence rate（χ2=32.981，P<0.05；χ2=4.554，P<0.05；χ2=86.695，P<0.05）. The differences between migrant workers and local workers were also significant in the basic medical insurance coverage rate and the level of satisfaction （χ2=221.592，P<0.05；χ2=30.950，P<0.05）. There was no significant difference in subjective well-being between these two groups（χ2=8.787，P>0.05）. The health self-assessment of older migrant workers was significantly better than that of new generation migrant workers（β=0.062，P<0.05）， and was significantly worse in female migrant workers than that in male migrant workers（β=-0.120，P<0.05）. The health self-assessment was significantly better in migrant workers with agricultural household registration than that in non-agricultural household registration（β=0.060，P<0.05）. The higher the satisfaction of basic medical insurance，the higher the subjective well-being and the better the health self-assessment（β=0.148，P<0.05；β=0.422，P<0.05）. Conclusion:The health status of migrant workers in Shanghai who received physical examination is better than that of local workers， and the participation rate of basic medical insurance is lower than that of local workers. Age， gender and household registration are the important factors influencing the health self-assessment. Satisfaction with basic medical insurance level and subjective well-being is a significant factor to predict health self-assessment positively . We should further improve the fairness of medical insurance benefits for migrant workers， improve subjective well-being， and ensure the health fairness of the group.
ABSTRACT
OBJECTIVE: To explore the effect of intervention adherence on the use of respiratory protective equipment(RPE) among migrant workers who occupationally exposed to organic solvents. METHODS: A total of 901 migrant workers from 60 small and medium-sized enterprises exposed to organic solvents in a district of Guangzhou City were selected as study subjects using three-arm cluster randomized controlled trial. The enterprises were divided into control group, intervention group, and combined intervention group. Migrant workers in the control group did not receive any intervention, while migrant workers in the intervention group received traditional health education and mobile health(mHealth) intervention, and migrant workers in the combined intervention group received interventions of the intervention group plus peer education. The use of RPE by the migrant workers was evaluated in these three groups in the last week, and at the sixth month. RESULTS: The adherence rates of the three mHealth intervention measures(following the WeChat official account of the project, joining the WeChat/QQ group of the project, and reading the provided messages from project team) in the combined intervention group were higher than that in the intervention group(74.8% vs 53.6%, 70.7% vs 41.8%, 78.5% vs 65.0%, all P<0.01). In the two intervention groups, the adherence rates of traditional health education(attending occupational health training, and browsing public welfare posters) were higher than that of mHealth intervention and/or peer education(all P<0.01). Logistic regression analysis showed that regardless of mHealth intervention, traditional health education or peer education, the high compliance subgroups of the two intervention groups were more likely to wear RPE all the time(all P<0.05) compared with the control group. The intervention effectiveness of the combined intervention group was better than that of the intervention group. CONCLUSION: Improving compliance with occupational health education interventions can promote the use of RPE among migrant workers. The implementation of peer education is beneficial to improve intervention compliance and intervention effect of migrant workers.
ABSTRACT
Objective: The aim of this study was to determine the prevalence and factors influencing alcohol consumption behavior of migrant workers. Method: A community-based analytical cross-sectional study was carried out on 559 samples drawn from 15 communities of the lower northern region of Thailand through a multistage random sampling technique. Descriptive statistics were used to describe basic socio-demographic characteristics, Chi-square tests were used for the univariate analyses to determine the relationship between the study outcome and other demographic characteristics. A binary logistic regression was used for the multivariate analyses to investigate factors associated with the research outcome. Result: The results revealed a 65.5% prevalence of alcohol consumption. Being male, above 30 years, in permanent employment, Agriculture-related jobs, living in a factory dormitory, having no relatives in Thailand, and earning between 5,000-10,000 Baht monthly were significant risk factors for alcohol consumption. However, being married, with over 5 years of work experience, and living in a comfortable condition were mitigating factors for alcohol consumption. Conclusion: Given the exceedingly high prevalence of alcohol consumption in the migrant workers’ communities, it is, therefore, imperative to enforce and continuously reinforce alcohol control laws, with the provision of specially designed health promotion and education programs in order to achieve a long-lasting reduction in alcohol consumption.
ABSTRACT
To examine the potential risk of hepatitis B virus (HBV) spread in Indonesia by migrant workers, based on the molecular characteristics of HBV strains. Methods: Sera collected from migrant workers traveling to their destination countries (pre-migrant workers) and those returning to Indonesia (post-migrant workers) were screened for HBsAg by ELISA, followed by HBV DNA detection by PCR and (sub) genotype/subtype determination according to surface region and whole genome sequencing. Results: Of 87 pre-migrant workers, 15 (17.24%) were HBsAgpositive, whereas 15 (12.10%) of 124 post-migrant workers were HBsAg seropositive. HBV genotype analysis based on the S region showed that HBV-B3/adw2 was predominant (96.15%, 25/26) whereas 3.85% (1/26) of isolates were HBV-C3/adrq+. Whole genome sequencing of selected strains and phylogenetic tree analysis identified subgenotype B7 in three samples previously categorized as subgenotype B3 based on S region analysis, supporting a recent argument that subgenotypes B5/B7/B8/B9 could be considered as a quasi-subgenotype of B3. Conclusions: A high prevalence of HBsAg carriers was detected among migrant workers from Lombok Island, with no significant difference in prevalence between before and after returning to Indonesia. All strains were classified into genotypes common in Indonesia, and the results suggested that migrant workers are not a risk factor for HBV transmission into Indonesia.
ABSTRACT
Objective To investigate the status of hepatitis B virus (HBV) infection and hepatitis B vaccination in junior middle school children of migrant workers in Pudong New Area of Shanghai, so as to provide evidence for prevention and treatment of hepatitis B. Methods A total of 298 children of migrant workers were recruited from junior middle schools of five communities in Pudong New Area, where migrant workers gathered. Questionnaire survey and HBV serological test were conducted. Results The 298 students had a hepatitis B vaccination coverage rate of 70.8% (211/298) and the whole-course vaccination coverage rate of 48.3% (144/298). The vaccination coverage rate of ethnic minority students was significantly lower than that of Han students (P<0.01). The vaccination coverage rate of children whose fathers were private business owners was the highest (P<0.001). The vaccination coverage rate of children whose fathers had junior college or above education background was significantly higher than those whose fathers had a lower one (P<0.01). The positive rates of hepatitis B virus surface antigen (HBsAg) and hepatitis B virus core antibody (HBcAb) in these children were 2.3% (7/298) and 4.7% (14/298), respectively. HBV infected family member was the independent influencing factors for positive HBsAg or HBcAb (P<0.01). HBsAb positive rate was 36.6% (109/298) in these children, with that of ethnic minority students being significantly higher than that of Han students (P<0.05). The proportion of low hepatitis B virus surface antibody (HBsAb) titer (10 mU/mL≤HBsAb<100 mU/mL) in Han students was higher than that of ethnic minority students, while the proportions of normal level (100 mU/mL≤HBsAb<1 000 mU/mL) and high level (HBsAb≥1 000 mU/mL) of ethnic minority students were significantly higher than those of Han students (P<0.05). Conclusion The hepatitis B vaccination coverage rate is relatively low in junior middle school children of migrant workers, and the positive rates of HBsAg and HBcAb are slightly higher, and these children are important targets for hepatitis B prevention and treatment in Shanghai and other megacities in the future. Health management and education of hepatitis B prevention and treatment should be strengthened for migrant workers and their children.
ABSTRACT
Background@#There is an increasing number of distressed Overseas Filipino Workers (OFWs) due to adverse working conditions and unresolved post-repatriation issues. The enactment of the Republic Act 11036 (Mental Health Act) in 2018 supports the commitment of the State in promoting and protecting the mental health of every Filipino. @*Methods@#A systematic review of literature was conducted to generate evidence-based policy tools for the round table discussion conducted by the UP Manila Health Policy Development Hub, engaging all major stakeholders from all sides of the policy issue. Strengths and challenges of the current government initiatives in the phases of predeployment, deployment, repatriation, and reintegration were discussed to attain consensus policy recommendations. @*Results@#Increased migration led to a cascade of distressed OFWs and their subsequent need for trained mental health professionals. In host countries, challenges in on-site services include (i) limited psychiatry practice as prescribed by law of the host countries, (ii) reciprocity of the host country in allowing more welfare officers, and (iii) budget to support more plantilla items of Assistance to Nationals (ATN) staff. The inter-agency collaboration and legal support for all phases of migration should be holistic and set. @*Conclusions and Recommendations@#From the literature review and policy discussion, consensus recommendations included strengthening pre-deployment preparation, curbing the trafficking of minors, improving psychiatry practice through the Bilateral Labor Agreement, developing psychosocial counseling competencies among front line host country personnel, enhancing telecounselling services and exploring telemedicine, among others.

Objective To evaluate the current status of sexual and reproductive health knowledge and behavior of young migrant workers in Shanghai, which would provide information for the development of intervention measures. Methods A cluster random sampling with self-filled questionnaires was used for survey in two factories of Shanghai.The total number of young migrant workers surveyed was 713.The questionnaire contents included socioeconomic characters, knowledge, attitude and behavior of sex and reproductive health. Results There were 428 males and 285 females ranged from 17 to 24 years old.Eighty-eight percent of them were from rural area of China, and 79.7% of them were unmarried.Their awareness of sexual and reproductive health was low, including misunderstandings of sexually transmitted diseases and HIV transmission pathways, and failure to realize the difference between condom and contraceptive pills.Only 46.5% of the males and 31.5% of the females answered correctly about the role of contraceptive pills.Their sexual attitude was open on premarital sex and cohabitation.Males were more tolerant than women; 59.1% of the males thought they could have sex before marriage if they got consent, which was much higher than females (39.6%, P < 0.01).While the rate of premarital sex was high (64.0% in males and 56.1% in females), sexual safety awareness was not strong.The rate of condom use was only 20%, and 12.4% of the females had unwilling pregnancy and abortion. Conclusion The sexual and reproductive health status in young migrant workers need to be improved by strengthening health education and health promotion.

ABSTRACT
Objective:To investigate the suicidal ideation among unmarried female migrant workers in Shanghai and Guangzhou and explore the association between suicidal ideation and some psychosocial problems, reproductive health factors. Methods:A questionnaire survey was conducted among 3 553 unmarried female migrant workers in two factories in Shanghai and two in Guangzhou by convenient sampling. Logistic regression was used to analyze the related factors of suicide ideation including psychosocial problems and reproductive health factors. Results:Overall, 287(8.1%) of the respondents had suicidal ideation during the past year. Univariate Logistic regression showed that alcohol, low self-esteem, depression, anxiety, loneliness, poor social support (emotional support and economic support), favorable attitude toward premarital pregnancy, favorable attitude toward multiple induced abortion, experience of unplanned pregnancy and experience of induced abortion were related to suicidal ideation after demographic factors being corrected. Multivariate Logistic regression showed that alcohol (OR=1.42, 95% CI 1.04-1.93), low self-esteem (OR=1.47, 95% CI 1.03-2.11), loneliness (OR=3.30, 95% CI 2.42-4.51), poor emotional support (OR=2.68, 95% CI 2.00-3.61) and poor economic support (OR=3.79, 95% CI 2.86-5.04) were the critical factors. Conclusion:The factors such as risk behavior, mental health, lack of social support were associated with increased odds for suicidal ideation among the unmarried female migrant workers. The prevention and intervention mechanism should be constructed, and the social support should be enhanced to effectively prevent the occurrence of suicidal ideation.
ABSTRACT
Background: Construction industry is one of the stable growing industries of the world and construction labour form 7.5% of the world labour force. In India, it is the largest economic activity after agriculture. Migrant construction workers are at a greater risk of developing certain health disorders and sickness than workers in many other industries. The objective was to study the socio demographic profile, morbidity profile among construction workers.Methods: A cross sectional study conducted at two construction sites in southern Bangalore and all workers were enrolled as study subjects. Data was collected using a pretested semi structured questionnaire. Statistical analysis used: descriptive statistics like percentages and Chi square test for test of significance.Results: Majority of the study population belonged to 15-45 years age group (87.3%), class IV (40.3%) socioeconomic status, Hindu religion (85%). Around 40% of them were illiterates and 68% of them were unskilled workers, rest semiskilled workers. Around 50% were from Raichur district of North Karnataka. Prevalence of injury was 8%, musculo-skeletal problems were around 50% followed by respiratory infections and gastrointestinal infections.Conclusions: The prevalence of musculoskeletal problems, respiratory problems and gastrointestinal infections was reported to be high among unskilled and semiskilled construction workers. There is need for health education and other prevention strategies for control of the same. Measures are needed to improve the work environment of construction workers by ensuring availability of personal protective equipments, good living conditions and sanitation facilities at the sites.
ABSTRACT
To investigate the status of Strongyloides(S.) stercoralis infections among migrant workers in Malaysia for the first time and identify risk factors. Methods: Four diagnostic methods were employed for the detection of S. stercoralis including microscopy, enzyme-linked immunosorbent assay (ELISA) using a commercial kit, ELISA using the rSs1a antigen and polymerase chain reaction (PCR). Low and semi-skilled workers from five working sectors (i.e. manufacturing, food service, agriculture and plantation, construction and domestic service) were tested on a voluntary basis. Results: The overall seroprevalence of S. stercoralis from 483 workers employing the ELISA commercial kit for IgG was 35.8% (n=173; 95% CI: 31.5%-40.1%) whereas seroprevalence using the rSs1a-ELISA was 13.0% (n=63; 95% CI: 10.0%-16.0%). Cross tabulation between the ELISA commercial kit and rSs1a-ELISA showed that only 6.4% (n=31; 95% CI: 4.2%-8.6%) of the samples were positive in both tests. Microscopic examination of all 388 fecal samples were negative; however subsequent testing by a nested PCR against DNA from the same samples successfully amplified DNA from three male subjects (0.8%; 3/388). Male workers, India and Myanmar nationality, food service occupation and those living in the hostel were statistically significant with seroprevalence (P<0.005). Conclusion: This is the first report on the epidemiology of S. stercoralis infections among the migrant workers in Malaysia. Our results highlight the importance of using appropriate diagnostic tools for detection. The presence of anti-S. stercoralis antibodies in the study population calls for improvements in personal hygiene and sanitation standards among migrant workers in Malaysia through control strategies including health education campaigns and programs aimed at increasing awareness and healthy behaviors.
ABSTRACT
Objective@#To explore the incidence regularity and characteristics of pneumoconiosis among migrant workers in Shiyan city, and to provide a basis for making policies about pneumoconiosis prevention and treatment among migrant workers.@*Methods@#In September 2018, 338 cases of pneumoconiosis among migrant workers and 354 cases of pneumoconiosis among non-migrant workers were collected between 2013 and 2017. The proportions of pneumoconiosis types, the age and seniority of onset workers, the severity grade of pneumoconiosis, the type of pneumoconiosis, the type of work and regional distribution, etc. were analyzed.@*Results@#The age at onset of pneumoconiosisand the length of service of migrant workers and non-migrant workers in Shiyan city were significantly different (t=2.237, 3.208, P<0.05) . The proportion of pneumoconiosis stage was significantly different from that of non-migrant workers (χ2=47.897, P<0.05) , among migrant workers, the types of pneumoconiosis were mainly silicosis (308 cases, 91.1%) , coal worker's pneumoconiosis (29 cases, 8.6%) . The leading work types are rock drilling (115 cases, 34.0%) and blasting (105 cases, 31.1%) . The industry was mainly engaged in non-ferrous metal mining (205 cases, 60.7%) and coal (105 cases, 31.1%) . The area distribution involved each counties of Shiyan city, with Zhushan county (175 cases, 51.8%) and Yunxi county (125 cases, 37.0%) as the top two districts in number of cases. Of the cases of migrant workers, 89 cases (26.3%) had blood relationship with any others. There was no work-related injury insurance for migrant workers with pneumoconiosis.@*Conclusion@#There is a high incidence of pneumoconiosis among migrant workers in Shiyan city, featured with the phenomenon of "late occurrence" and "family clustering", so it is urgent to strengthen the prevention and treatment of pneumoconiosis of migrant workers.
ABSTRACT
Objective@#To analyze the prevalence of pneumoconiosis and assistance guarantee of the migrant workers of the district in Chongqing from 2006 to 2017, so as to provide scientific basis for prevention and control of pneumoconiosis of the migrant workers.@*Methods@#The database of new pneumoconiosis cases of the migrant workers and assistance guarantee of the district in Chongqing from 2006 to 2017 were subjected to systematic arrangement. SPSS 18.0 was adopted for statistical description and analysis.@*Results@#From 2006 to 2017 a total of 2188 new cases of pneumoconiosis were diagnosed, including I (917, 41.91%) , II (1003, 45.84%) , III (268, 12.25%) . Most of new cases of pneumoconiosis were silicosis. The median length of seniority was 6 years. The mean diagnostic age was 44.25. Significant difference was found in diagnosis age between different stages (F=3.161, P=0.043) . 98.77% of migrant workers had no units. There were 5.07% of migrant workers who took out industrial injury insurance, 14.58% receiving civil aid, 31.12% receiving aid from poverty alleviation, and 93.46% participating medical insurance.@*Conclusion@#The prevalence of pneumoconiosis of the migrant workers of the district in Chongqing was serious. The prevention and control of pneumoconiosis should be enhanced to reduce the harm of pneumoconiosis of the migrant workers in Chongqing.
ABSTRACT
Objective@#To explore the prevalence of occupational musculoskeletal disorders (OMD) and its influencing factors among rural migrant workers in Tianjin, with the aim of developing strategies to improve the health condition of this specific population.@*Methods@#Questionnaire survey was conducted among 415 rural migrant workers working in Tianjin about their fundamental state and occupational musculoskeletal disorders (OMD) during January 2015 to January 2016. Statistical methods were utilized to analyze the influencing factor.@*Results@#A total of 415 rural migrant workers were investigated, in which young Young adults and low education level were in the majority of rural migrant workers. The prevalence of OMD for whole population, male and female were 28.92% (120/415), 33.06% (81/245) and 22.94% (39/170), respectively. Prevalence showed significant differences njin and workplace hygiene. Multivariate logistic regression analysis showed that the risks of OMD increased with age group, and decreased with higher education level. The risk of OMD among rural migrant workers with monthly income between 3000 to 5000 yuan was 2.26 times (95%CI: 1.37-3.75) higher than that of low-income workers (<3000 yuan per month). Workers engaged in housekeeping service had 2.28 times higher risk of OMD than those in manufacturing industry (95%CI: 1.06-4.89) .@*Conclusion@#Prevalence of OMD among rural migrant workers is higher than that of general people. Age, education, monthly income, occupation are the independent influencing factors for OMD among rural migrant workers.
ABSTRACT
To investigate the status of Strongyloides(S.) stercoralis infections among migrant workers in Malaysia for the first time and identify risk factors. Methods: Four diagnostic methods were employed for the detection of S. stercoralis including microscopy, enzyme-linked immunosorbent assay (ELISA) using a commercial kit, ELISA using the rSs1a antigen and polymerase chain reaction (PCR). Low and semi-skilled workers from five working sectors (i.e. manufacturing, food service, agriculture and plantation, construction and domestic service) were tested on a voluntary basis. Results: The overall seroprevalence of S. stercoralis from 483 workers employing the ELISA commercial kit for IgG was 35.8% (n=173; 95% CI: 31.5%-40.1%) whereas seroprevalence using the rSs1a-ELISA was 13.0% (n=63; 95% CI: 10.0%-16.0%). Cross tabulation between the ELISA commercial kit and rSs1a-ELISA showed that only 6.4% (n=31; 95% CI: 4.2%-8.6%) of the samples were positive in both tests. Microscopic examination of all 388 fecal samples were negative; however subsequent testing by a nested PCR against DNA from the same samples successfully amplified DNA from three male subjects (0.8%; 3/388). Male workers, India and Myanmar nationality, food service occupation and those living in the hostel were statistically significant with seroprevalence (P<0.005). Conclusion: This is the first report on the epidemiology of S. stercoralis infections among the migrant workers in Malaysia. Our results highlight the importance of using appropriate diagnostic tools for detection. The presence of anti-S. stercoralis antibodies in the study population calls for improvements in personal hygiene and sanitation standards among migrant workers in Malaysia through control strategies including health education campaigns and programs aimed at increasing awareness and healthy behaviors.
