Household Food Insufficiency, Financial Strain, Work–Family Spillover, and Depressive Symptoms in the Working Class: The Work, Family, and Health Network Study

OBJECTIVES We evaluated the association of household-level stressors with depressive symptoms among low-wage nursing home employees. METHODS Data were collected in 2006 and 2007 from 452 multiethnic primary and nonprimary wage earners in 4 facilities in Massachusetts. We used logistic regression to estimate the association of depressive symptoms with household financial strain, food insufficiency, and work-family spillover (preoccupation with work-related concerns while at home and vice versa). RESULTS Depressive symptoms were significantly associated with household financial strain (odds ratio [OR] = 1.82; 95% confidence interval [CI] = 1.03, 3.21) and food insufficiency (OR = 2.10; 95% CI = 1.10, 4.18). Among primary earners, stratified analyses showed that food insufficiency was associated with depressive symptoms (OR = 3.60; 95% CI = 1.42, 9.11) but financial strain was not. Among nonprimary wage earners, depressive symptoms correlated with financial strain (OR = 3.65; 95% CI = 1.48, 9.01) and work-family spillover (OR = 3.22; 95% CI = 1.11, 9.35). CONCLUSIONS Household financial strain, food insufficiency, and work-family spillover are pervasive problems for working populations, but associations vary by primary wage earner status. The prevalence of food insufficiency among full-time employees was striking and might have a detrimental influence on depressive symptoms and the health of working-class families.

Work and family demands: predictors of all-cause sickness absence in the GAZEL cohort

BACKGROUND The aim of this study is to assess the impact of combined work and family demands on all-cause sickness absence and to examine variation in this relationship by occupational grade and gender. METHODS The study sample consists of 13,179 employees of Electricité de France-Gaz de France (EDF-GDF) who were members of the GAZEL occupational cohort in 1995. Combined work and family demands are assessed based on measures of job strain and number of dependants assessed at baseline (1995). Covariates include occupational grade and demographic, behavioural and social variables assessed at baseline. Ratios of sickness absence days to total person-days contributed by each employee were established from administrative data between baseline and the end of follow-up in 2003. Rate ratios across levels of work-family demands were then calculated. Effect modification by gender and grade of employment was tested. RESULTS In fully adjusted models, individuals with the highest work-family demands had a rate ratio of sickness absence of 1.78 (95% CI 1.47-2.14) compared with low-demand workers. This association was independent of occupational grade and did not vary with gender. Results were not attributable solely to psychiatric sickness absences. CONCLUSION High work-family demands at baseline predict long-term all-cause sickness absence across a socio-economically diverse occupational cohort.

Occupational solvent exposure and cognition: does the association vary by level of education?

Objective: Chronic occupational solvent exposure is associated with long-term cognitive deficits. Cognitive reserve may protect solvent-exposed workers from cognitive impairment. We tested whether the association between chronic solvent exposure and cognition varied by educational attainment, a proxy for cognitive reserve. Methods: Data were drawn from a prospective cohort of French national gas and electricity (GAZEL) employees (n = 4,134). Lifetime exposure to 4 solvent types (chlorinated solvents, petroleum solvents, benzene, and nonbenzene aromatic solvents) was assessed using a validated job-exposure matrix. Education was dichotomized at less than secondary school or below. Cognitive impairment was defined as scoring below the 25th percentile on the Digit Symbol Substitution Test at mean age 59 (SD 2.8; 88% of participants were retired at testing). Log-binomial regression was used to model risk ratios (RRs) for poor cognition as predicted by solvent exposure, stratified by education and adjusted for sociodemographic and behavioral factors. Results: Solvent exposure rates were higher among less-educated patients. Within this group, there was a dose-response relationship between lifetime exposure to each solvent type and RR for poor cognition (e.g., for high exposure to benzene, RR = 1.24, 95% confidence interval 1.09–1.41), with significant linear trends (p < 0.05) in 3 out of 4 solvent types. Recency of solvent exposure also predicted worse cognition among less-educated patients. Among those with secondary education or higher, there was no significant or near-significant relationship between any quantification of solvent exposure and cognition. Conclusions: Solvent exposure is associated with poor cognition only among less-educated individuals. Higher cognitive reserve in the more-educated group may explain this finding.

Mothering alone: cross-national comparisons of later-life disability and health among women who were single mothers

Background Single motherhood is associated with poorer health, but whether this association varies between countries is not known. We examine associations between single motherhood and poor later-life health in the USA, England and 13 European countries. Methods Data came from 25 125 women aged 50+ who participated in the US Health and Retirement Study, the English Longitudinal Study of Ageing and Survey of Health, Ageing and Retirement in Europe. We tested whether single motherhood at ages 16–49 was associated with increased risk of limitations with activities of daily living (ADL), instrumental ADL and fair/poor self-rated health in later life. Results 33% of American mothers had experienced single motherhood before age 50, versus 22% in England, 38% in Scandinavia, 22% in Western Europe and 10% in Southern Europe. Single mothers had higher risk of poorer health and disability in later life than married mothers, but associations varied between countries. For example, risk ratios for ADL limitations were 1.51 (95% CI 1.29 to 1.98) in England, 1.50 (1.10 to 2.05) in Scandinavia and 1.27 (1.17 to 1.40) in the USA, versus 1.09 (0.80 to 1.47) in Western Europe, 1.13 (0.80 to 1.60) in Southern Europe and 0.93 (0.66 to 1.31) in Eastern Europe. Women who were single mothers before age 20, for 8+ years, or resulting from divorce or non-marital childbearing, were at particular risk. Conclusions Single motherhood during early-adulthood or mid-adulthood is associated with poorer health in later life. Risks were greatest in England, the USA and Scandinavia. Selection and causation mechanisms might both explain between-country variation.

Racial disparities in job strain among American and immigrant long-term care workers

BACKGROUND Nursing homes are occupational settings, with an increasing minority and immigrant workforce where several psychosocial stressors intersect. AIM This study aimed to examine racial/ethnic differences in job strain between Black (n = 127) and White (n = 110) immigrant and American direct-care workers at nursing homes (total n = 237). METHODS Cross-sectional study with data collected at four nursing homes in Massachusetts during 2006-2007. We contrasted Black and White workers within higher-skilled occupations such as registered nurses or licensed practical nurses (n = 82) and lower-skilled staff such as certified nursing assistants (CNAs, n = 155). RESULTS Almost all Black workers (96%) were immigrants. After adjusting for demographic and occupational characteristics, Black employees were more likely to report job strain, compared with Whites [relative risk (RR): 2.9, 95% confidence interval (CI) 1.3 to 6.6]. Analyses stratified by occupation showed that Black CNAs were more likely to report job strain, compared with White CNAs (RR: 3.1, 95% CI: 1.0 to 9.4). Black workers were also more likely to report low control (RR: 2.1, 95% CI: 1.1 to 4.0). Additionally, Black workers earned

Physical Activity and Body Mass Index: The Contribution of Age and Workplace Characteristics

2.58 less per hour and worked 7.1 more hours per week on average, controlling for potential confounders. CONCLUSION Black immigrant workers were 2.9 times more likely to report job strain than White workers, with greater differences among CNAs. These findings may reflect differential organizational or individual characteristics but also interpersonal or institutional racial/ethnic discrimination. Further research should consider the role of race/ethnicity in shaping patterns of occupational stress.

Integrating worksite health protection and health promotion: A conceptual model for intervention and research.

BACKGROUND The workplace is an important domain for adults, and many effective interventions targeting physical activity and weight reduction have been implemented in the workplace. However, the U.S. workforce is aging, and few studies have examined the relationship of BMI, physical activity, and age as they relate to workplace characteristics. PURPOSE This paper reports on the distribution of physical activity and BMI by age in a population of hospital-based healthcare workers and investigates the relationships among workplace characteristics, physical activity, and BMI. METHODS Data from a survey of patient care workers in two large academic hospitals in the Boston area were collected in late 2009 and analyzed in early 2013. RESULTS In multivariate models, workers reporting greater decision latitude (OR=1.02, 95% CI=1.01, 1.03) and job flexibility (OR=1.05, 95% CI=1.01, 1.10) reported greater physical activity. Overweight and obesity increased with age (p<0.01), even after adjusting for workplace characteristics. Sleep deficiency (OR=1.56, 95% CI=1.15, 2.12) and workplace harassment (OR=1.62, 95% CI=1.20, 2.18) were also associated with obesity. CONCLUSIONS These findings underscore the persistent impact of the work environment for workers of all ages. Based on these results, programs or policies aimed at improving the work environment, especially decision latitude, job flexibility, and workplace harassment should be included in the design of worksite-based health promotion interventions targeting physical activity or obesity.

Occupational injury among hospital patient-care workers: what is the association with workplace verbal abuse?

There is increasing recognition of the value added by integrating traditionally separate efforts to protect and promote worker safety and health. This paper presents an innovative conceptual model to guide research on determinants of worker safety and health and to inform the design, implementation and evaluation of integrated approaches to promoting and protecting worker health. This model is rooted in multiple theories and the premise that the conditions of work are important determinants of individual safety and health outcomes and behaviors, and outcomes important to enterprises such as absence and turnover. Integrated policies, programs and practices simultaneously address multiple conditions of work, including the physical work environment and the organization of work (e.g., psychosocial factors, job tasks and demands). Findings from two recent studies conducted in Boston and Minnesota (2009-2015) illustrate the application of this model to guide social epidemiological research. This paper focuses particular attention on the relationships of the conditions of work to worker health-related behaviors, musculoskeletal symptoms, and occupational injury; and to the design of integrated interventions in response to specific settings and conditions of work of small and medium size manufacturing businesses, based on a systematic assessment of priorities, needs, and resources within an organization. This model provides an organizing framework for both research and practice by specifying the causal pathways through which work may influence health outcomes, and for designing and testing interventions to improve worker safety and health that are meaningful for workers and employers, and responsive to that settings conditions of work.

Use of life course work-family profiles to predict mortality risk among US women.

OBJECTIVE To test the association between workplace abuse exposure and injury risk among hospital workers. We hypothesized that exposed workers would have higher injury rates than unexposed workers. METHODS Survey of direct-care workers (n = 1,497) in two hospitals. Exposure to workplace abuse was assessed through self-report; occupational injury reports were extracted from employee records. We tested associations between non-physical workplace violence and injury using log-binomial regression and multilevel modeling. RESULTS Adjusted prevalence ratio (PR) for injury associated with being yelled at was 1.52 (95% CI 1.19, 1.95); for experiencing hostile/offensive gestures 1.43 (1.11, 1.82); and for being sworn at 1.41 (1.09, 1.81). In analyses by injury subtypes, musculoskeletal injuries were more strongly associated with abuse than were acute traumatic injuries. Associations operated on group and individual levels and were most consistently associated with abuse perpetrated by patients. CONCLUSION Exposure to workplace abuse may be a risk factor for injuries among hospital workers.

Time may not fully attenuate solvent-associated cognitive deficits in highly exposed workers

OBJECTIVES We examined relationships between US womens exposure to midlife work-family demands and subsequent mortality risk. METHODS We used data from women born 1935 to 1956 in the Health and Retirement Study to calculate employment, marital, and parenthood statuses for each age between 16 and 50 years. We used sequence analysis to identify 7 prototypical work-family trajectories. We calculated age-standardized mortality rates and hazard ratios (HRs) for mortality associated with work-family sequences, with adjustment for covariates and potentially explanatory later-life factors. RESULTS Married women staying home with children briefly before reentering the workforce had the lowest mortality rates. In comparison, after adjustment for age, race/ethnicity, and education, HRs for mortality were 2.14 (95% confidence interval [CI] = 1.58, 2.90) among single nonworking mothers, 1.48 (95% CI = 1.06, 1.98) among single working mothers, and 1.36 (95% CI = 1.02, 1.80) among married nonworking mothers. Adjustment for later-life behavioral and economic factors partially attenuated risks. CONCLUSIONS Sequence analysis is a promising exposure assessment tool for life course research. This method permitted identification of certain lifetime work-family profiles associated with mortality risk before age 75 years.
