Work-Related Injury and Healthcare Access Among Day Laborers. Struggling at the Esquina.

California has a significant day laborer population, with about one-third of the total U.S. day laborer population working in the state.

Developing a short standard questionnaire for assessing work organization hazards: the Healthy Work Survey (HWS).

Background: At present, no short standard questionnaire exists for assessing and comparing major work organization hazards in the workplaces of the United States.

Methods: We conducted a series of psychometric tests (content validity, factor analysis, differential-item functioning analysis, reliability, and concurrent validity) to validate and identify core items and scales for major work organization hazards using the data from the 2002-2014 General Social Surveys (GSSs), including the Quality of Worklife (QWL) questionnaire. In addition, an extensive literature review was undertaken to find other major work organization hazards which were not addressed in the GSS.

Comparison of Social Inequality in Human Papillomavirus (HPV) Vaccination among Teenagers with Parental Reports and Healthcare Providers' Records in the 2019 National Immunization Survey-Teen.

Background: Relatively little is known about social inequality in human papillomavirus (HPV) vaccination among teenagers in the United States. This study aims to investigate whether there is a social disparity in HPV vaccination among teenagers and if so, whether it can differ according to the source of teen vaccination information (parental reports and provider records).

Methods: We used the data from the 2019 National Immunization Survey-Teen (NIS-Teen; 42,668 teenagers, aged 13-17) including parent-reported vaccination status.

Developing a Job Exposure Matrix of Work Organization Hazards in the United States: A Review on Methodological Issues and Research Protocol.

Background: Most job exposure matrices (JEMs) have been developed for chemical and physical hazards in the United States (US). In addition, the overall validity of most JEMs of work organization hazards using self-reported data in the literature remains to be further tested due to several methodological weaknesses.

Methods: This paper aims to review important methodological issues with regard to a JEM of work organization hazards using self-report data and to present a research protocol for developing a four-axis (job titles, hazards, sex, and time) JEM of major work organization hazards using the US General Social Survey-Quality of Work-Life (GSS-QWL) data (2002-2018; N = 7,100 workers).

Urinary bisphenol A, phthalate metabolites, and obesity: do gender and menopausal status matter?

Previous studies of urinary bisphenol A (BPA), phthalate metabolites, and obesity risk have shown inconsistent results. Menopausal status is one of the main factors that affect hormone secretion change in women. In this study, we examined whether urinary BPA and phthalate metabolite levels are associated with obesity and whether the associations differ by sex and menopausal status in a sample of Korean adult populations.

Opioid use disorder, job strain, and high physical job demands in US workers.

Purpose: Little is known about the work environmental risk factors for opioid use disorder (OUD) in working populations. The purpose of this study is to examine whether adverse physical and psychosocial working conditions are associated with OUD in a working population of the United States (US).

Methods: Among the participants of the National Survey of Midlife Development in the United States (MIDUS) II Study (2004-2006), 2134 workers (1059 men and 1075 women; mean age, 51 years) were chosen for this study.

Workplace breastfeeding support and job satisfaction among working mothers in the United States.

Background: Job satisfaction is associated with health and productivity. Workplace support for breastfeeding may affect working mothers' job satisfaction.

Methods: We analyzed responses from 488 women from the Infant Feeding Practices Study II (2005-2007).

Nonlinear Relationship Between Blood Pressure and Glaucoma in US Adults.

Background: Previous studies have reported that vascular disease is associated with glaucoma. However, the relationship between blood pressure (BP) and glaucoma has been inconsistent. We investigated whether there is a nonlinear association between BP and glaucoma in an adult population of the United States.

Resting heart rate, heart rate reserve, and metabolic syndrome in professional firefighters: A cross-sectional study.

Background: Little is known about the associations of resting heart rate (RHR) and heart rate reserve (HRR) with metabolic syndrome (MetS) in firefighters.

Methods: For each of 288 professional firefighters, HRR was calculated as the difference between measured RHR and estimated maximum HR. For comparison, VO max based on a treadmill test was included.

Work organization, health, and obesity in urban transit operators: A qualitative study.

Background: Urban transit operators have high rates of obesity, hypertension, and other cardiovascular risk-factors compared to other occupations. There have been few qualitative studies exploring the interrelationships between the organization of transit work, stress, and health including obesity, from the perspective of operators.

Methods: Five focus groups were conducted at five Divisions in a transit authority in Southern California and included 65 bus and rail operators.
