Prevalence and Geographic Distribution of Self-Reported Chronic Kidney Disease and Potential Risk Factors in Central America.

Background: Cases for chronic kidney disease of unknown etiology (CKDu) are increasing in specific disease hotspots located in rural agricultural communities over Central America. The goal of the study was to estimate the prevalence and geographic distribution of self-reported work-related CKD and associated risk factors for CKDu by industry sector in Central America.

Methods: We calculated the prevalence and distribution of self-reported CKD, work-related CKD, and suspected CKDu risk factors among the 9032 workers in the Second Central American Survey of Working Conditions and Health (II ECCTS, 2018).

[Precarious employment Measurement in Central America: psychometric properties based on the II Central American Survey of Working Conditions and Health].

Objective: Identify the psychometric properties of a measure of Employment Precariousness (EP) in six Central American Spanish-speaking countries (Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama) through the items of the EPRES scale (Employment Precariousness Scale) included in the II Central American Survey of Working Conditions and Health (II ECCTS) of 2018.

Methods: The sample was 3,782 salaried persons, aged 18 and older, formal and informal, who participated in the II ECCTS. An EP measure of 10 items was constructed, grouped in the dimensions of temporality, salary, labor rights, and exercise of these rights.

Kidney Function in Rice Workers Exposed to Heat and Dehydration in Costa Rica.

The aim of this study was to evaluate heat exposure, dehydration, and kidney function in rice workers over the course of three months, in Guanacaste, Costa Rica. We collected biological and questionnaire data across a three-month-period in male field (n = 27) and other (n = 45) workers from a rice company where chronic kidney disease of unknown origin (CKDu) is endemic. We used stepwise forward regression to determine variables associated with estimated glomerular filtration rate eGFR at enrollment and/or change in eGFR, and Poisson regression to assess associations with incident kidney injury (IKI) over the course of three months.

Monitoring Self-Perceived Occupational Health Inequities in Central America, 2011 and 2018.

To analyze changes in occupational health inequity between 2011 and 2018 among workers in Central America. Data were collected by face-to-face interviews at the workers' homes for the 2 Central America Working Conditions Surveys (n  = 12 024 in 2011 and n = 9030 in 2018). We estimated health inequity gaps by means of absolute and relative population attributable risks and the weighted Keppel index.

Effect of informal employment on the relationship between psychosocial work risk factors and musculoskeletal pain in Central American workers.

Introduction: The constant increase on the psychosocial demands experienced at work seems to contribute to the increase in health problems such as musculoskeletal pain (MSP). This association may be especially important in low-income and middle-income countries, where there is a large proportion of informal workers among whom there is little research. We analysed the association between psychosocial work risk factors and MSP among formal and informal workers using the First Central American Survey of Working Conditions and Health.
