However, this has not been extensively studied in Africa. The aim of this study was therefore to determine the prevalence of obstructive lung disease and its relationship to concurrent nicotine and pesticide exposure among small-scale tobacco farmers in Malawi. For this purpose, sociodemographic characteristics, occupational and environmental exposures were evaluated in relation to work-related respiratory symptoms and lung function impairment. A cross-sectional study was conducted enrolling 279 workers in flue-cured tobacco farms in Zomba, Malawi. The study instruments used for assessing the health outcomes were a standardised European Community Respiratory Health Survey II (ECRHS) questionnaire and Spirometry testing. The questionnaires were aimed at collecting relevant data on sociodemographic factors and self-reported respiratory health outcomes. Data were also collected on potential pesticide and nicotine exposures. Spirometry was done to evaluate objective respiratory impairment in accordance with American Thoracic Society guidelines. The mean age of participants was 38 years with 68% being male. The prevalence of work-related ocular nasal symptoms, chronic bronchitis, and work-related chest symptoms was 20%, 17%, and 29%, respectively. Airflow limitation (FEV1/FVC <70%) was found in 8% of workers. Self-reported exposure to pesticides varied from 72%- to 83%, whilst the prevalence of recent green tobacco sickness was 26%. Tasks linked to nicotine exposure, such as sowing (OR: 2.5; CI 1.1-5.7) and harvesting (OR: 2.6; CI 1.4-5.1), were significantly associated with work-related chest symptoms. Pesticide application (OR:1.96; CI 1.0-3.7) was associated with an increased risk of work-related oculonasal symptoms. Duration of pesticide exposure was also associated with obstructive impairment FEV1/FVC<LLN (OR: 5.11; CI 1.6-16.7) and FEV1/FVC <70% (OR: 4.68; CI 1.2-18.0). This study demonstrated that tobacco farmers in Malawi had a high prevalence of respiratory symptoms and airflow limitation due to obstructive lung disease. This could be attributed to nicotine or pesticide exposure in small-scale tobacco farming. The implementation of occupational health and safety measures to mitigate these exposures may play an important role in modifying the risk of obstructive lung disease in this population.</p>","PeriodicalId":49172,"journal":{"name":"Journal of Agromedicine","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9886416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A gatekeeper is an individual who has been trained to recognize warning symptoms of possible suicidal ideations in others. Gatekeeper programs are recognized by the federal Substance Abuse and Mental Health Services Administration as a best practice for suicide prevention. While gatekeeper programs offer promise to addressing the increasing worldwide suicide rate, how to develop these networks in communities with largely ingrained stigma and taboo related to mental health and suicide remains unanswered. Three of this study's researchers were part of the development and pilot of an agricultural community gatekeeper program and questioned how gatekeeper instructor psychological comfort could be conceptualized and operationalized for the purpose of informing gatekeeper instructor recruitment and training. After a thorough review of the literature, the researchers constructed a conceptual developmental model of gatekeeper instructor comfort and created a Gatekeeper Instructor Comfort Measure instrument which was then piloted with Kentucky K-12 and university agricultural educators. The researchers of this study employed the Rasch model to determine whether the developmental model of gatekeeper instructor comfort held together empirically. Infit and outfit mean squares (0.73 to 1.33) indicate that the items measure one construct, or are unidimensional, while person reliability and separation statistics indicate that the Gatekeeper Instructor Comfort Measure is composed of enough items to differentiate respondents into almost four strata of gatekeeper comfort. The Gatekeeper Instructor Comfort Measure's fit to the Rasch model indicates that the instrument meets the requirements of invariant measurement and should serve as a useful measure for other researchers. The instrument's item difficulty hierarchy also serves as a guide for those training gatekeepers on how to target different gatekeeper outcomes sequentially or developmentally. Researchers recommend restructuring item responses to enable greater discrimination between categories and then piloting the instrument again with a more diverse sample. The revised measure could be used pre- and post-gatekeeper instructor training to determine the impact of training on gatekeeper comfort.</p>","PeriodicalId":49172,"journal":{"name":"Journal of Agromedicine","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9569503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
