Affordable measurement of core body temperature (Tc) in a continuous, real-time fashion is now possible. With this advance comes a new data analysis paradigm for occupational epidemiology. We characterize issues arising after obtaining Tc data over 188 workdays for 83 participating farmworkers, a population vulnerable to effects of rising temperatures due to climate change. We describe a novel approach to these data using smoothing and functional data analysis. This approach highlights different data aspects compared with describing Tc at a single time point or summaries of the time course into an indicator function (e...

In California's central valley, childhood obesity rates are above the national average. The majority of families living in the rural, agricultural communities of this region are immigrant of Mexican heritage, and face numerous social and environmental challenges. Demographic and anthropometric data were collected from a population of Mexican-heritage children 3-8 years (N = 609) and families (N = 466) living in two central valley communities. Overall, 45 % of children and 82 % of mothers were classified as overweight or obese...

PURPOSE: Visual impairment presents significant risks for occupational injuries among farmworkers, a vulnerable population with limited access to vision care. Although previous research has noted farmworkers' low lifetime experience with vision screening and high rates of complaints of eye ailments and poor vision, there have been few screening data collected to evaluate these self-reports. The objectives of this analysis are to (1) describe farmworker visual health using standardized visual acuity screening data and self-reported visual function, and (2) to compare the screening and self-report data...

A good understanding of underlying causes of obesity prevalence in the farmworker population is critical in finding effective strategies to fight obesity and related chronic diseases. There is growing evidence that the population of farmworkers fares poorly with regard to health status, but available data on obesity levels and related chronic diseases is scarce or missing. This study examined the prevalence of overweight and obesity among a sample of farmworker population in California. Results of the regression model indicate that along with demographic variables such as age and gender, several lifestyle and behavioral risk factors are associated with obesity of the farmworkers...

BACKGROUND: Recent studies have highlighted the increased potency of oxygen analogs of organophosphorus pesticides. These pesticides and oxygen analogs have previously been identified in the atmosphere following spray applications in California and Washington states. OBJECTIVES: In 2011, we used two passive sampling methods to measure organophosphorus pesticides chlorpyrifos, azinphos-methyl, and their oxygen analogs at 14 farmworker and 9 non-farmworker households in an agricultural region of central Washington State...

BACKGROUND: The original objective was to measure the impact of kneepads on musculoskeletal pain in migrant and seasonal farmworkers (MSFWs). Secondary analyses were conducted to quantify the extent to which response bias may have skewed the study's results. METHODS: Surveys were used to collect data on baseline pain and post-intervention pain, the amount of time participants spent wearing kneepads, and their overall ratings of the intervention. RESULTS: Participants did not experience significantly less pain with kneepads, and wore them for considerably less than the prescribed amount of time...

BACKGROUND: Syrian migrant farmworkers are among the most marginalized populations in Lebanon, living in poverty, lacking basic legal protections and frequent targets of discrimination. These realities produce living conditions that undermine their basic health and wellbeing. This study explores associations between household living conditions and acute and chronic health problems among Syrian migrant agricultural workers in the Bekaa region of Lebanon. METHODS: A survey was carried out in summer of 2011 with a sample of 290 migrant agriculture workers and members of their household living in a migrant farmworker camp...

PURPOSE: The occupational risk to farmworkers, particularly chronic exposure to pesticides, is an acknowledged environmental and work-related health problem. Epigenetics has recently been shown to contribute to a number of complex diseases and traits, including measures of cognitive function and preclinical neurodegenerative disease. We sought to determine whether changes in DNA methylation existed between farmworker and non-farmworker populations and to identify the genes most likely involved in those changes...

BACKGROUND: Farmworkers are at high-risk for tick bites, which potentially transmit various tick-borne diseases. Previous studies show that personal prevention against tick bites is key, and certain factors namely, knowledge, experience of tick bites, and health beliefs influence compliance with tick bites preventive behaviour. This study aimed to assess these factors and their associations with tick bite preventive practices among Malaysian farmworkers. METHODS: A total of eight cattle, goat and sheep farms in six states in Peninsular Malaysia participated in a cross-sectional survey between August and October 2013...

Organophosphate (OP) pesticides are widely used for crop protection in many countries including Thailand. Aside from causing environmental contamination, they affect human health especially by over-stimulating of the neurotransmission system. OP pesticides, as with other non-persistent pesticides, degrade quickly in the environment as well as are metabolized quite rapidly in humans. Assessing human exposures to these compounds requires analytical methods that are sensitive, robust, and most importantly, suitable for specific laboratory settings...
