Factors affecting lead dust in construction workers' homes in the Greater Boston Area.

Lead is a known reproductive, developmental, and neurological toxicant. Workers with a high likelihood of being exposed to lead at work may inadvertently transport lead home from work, known as "take-home exposure." This is concerning for many workers for whom a workplace intervention is not feasible because their worksites and employers often change, rendering centralized strategies insufficient. This study aimed to better understand the connection between lead in the home of workers living with children and work in construction (n = 23), while other occupations were used as a comparison group (janitorial n = 5, autobody n = 2). Thirty workers living in disadvantaged communities in the Greater Boston area were recruited in 2018-2019 through collaboration with non-profits and worker unions with expertise working with low-income or immigrant workers. Construction workers that performed renovations, bridge constructions, welding, metal work, and demolitions were prioritized during recruitment. During a visit to their residences, a worker questionnaire was administered, and observations and a dust vacuumed sample of the home were collected. Factors predicting lead in home dust were explored by a bivariate analysis and a multivariable regression model. We found lead in homes' dust in the range of 20-8,310 ppm. Homes of construction workers generally had higher and more variable lead dust concentrations (mean 775, max 8,300 ppm) than autobody and janitor worker homes combined (mean 296, max 579 ppm). Five of the construction workers' home lead dust concentrations exceeded US guidelines for yard soil in children's play areas of 400 ppm, and were similar to other studies of homes near lead smelters, superfund sites, or in the Boston area in the early 1990s, pointing to disparities relating to work. Results from the multivariable regression model suggest that lead dust in homes of workers was associated with sociodemographic-, home-, and work-related factors, and pointed to overlapping vulnerabilities; however, a larger sample size is needed to verify findings. Results provide evidence that work-related factors are important to consider when assessing home exposures, and that take-home exposures for workers in lead high-risk jobs such as construction may be an important source of exposure in the home prime for public health intervention at work, home, and community levels.

Electronic Partner Notification for Sexually Transmitted Infections: A Qualitative Assessment of Patient, Clinical Staff, and State Field Epidemiologist Perspectives.

In Massachusetts (MA), partner notification is routinely offered for new HIV and infectious syphilis cases, but there are no formal partner notification services for gonorrhea and chlamydia. Electronic partner notification (ePN), which allows patients to anonymously notify their partners of sexually transmitted infection exposure, could fill this gap. We evaluated the acceptability of and ideal characteristics for a statewide ePN service in MA. We performed semistructured interviews with patients at a Boston area sexual health clinic and conducted focus groups with clinicians and Massachusetts Department of Public Health Field Epidemiologists (FEs). We developed a codebook and thematically analyzed interview and focus group data; 25% of interviews were double coded. We identified six main themes from our data: (1) partner notification is a relational process and (2) partner notification is situation dependent. There are three pairs of challenges and core values for an effective ePN system: (3) stigmatization versus inclusivity, (4) trust versus mistrust, and (5) privacy versus helpful information sharing. Therefore, (6) a statewide ePN platform must be customizable at each possible step. Although ePN was acceptable across all three groups, the likelihood of individual use was grounded in a patient's sociocultural context, interpersonal relationships, trust in the platform and health authorities, desire to avoid stigmatization, and privacy needs. These factors are best accommodated by a platform that adapts to users' preferences and needs. ePN presents an opportunity to link partners at risk for gonorrhea or chlamydia to clinical care that is complementary to the more labor-intensive FE role.

Eliminating Take-Home Exposures: Recognizing the Role of Occupational Health and Safety in Broader Community Health.

Toxic contaminants inadvertently brought from the workplace to the home, known as take-home or paraoccupational exposures, have often been framed as a problem that arises due to unsanitary worker behavior. This review article conceptualizes take-home exposures as a public health hazard by (i) investigating the history of take-home contaminants and how they have been studied, (ii) arguing that an ecosocial view of the problem is essential for effective prevention, (iii) summarizing key structural vulnerabilities that lead populations to be at risk, and (iv) discussing future research and prevention effort needs. This article reframes take-home exposures as one of many chronic pathways that contributes to persistent health disparities among workers, their families, and communities. Including the role of work in community health will increase the comprehensiveness of prevention efforts for contaminants such as lead and pesticides that contribute to environmental disparities.
