Informal Employment Under the Skin: Informality and Health Inequalities Among Chilean Workers

Informal employment has been identified as an important social determinant of health. This article addresses the processes through which informal employment affects workers' health in Chile. The study's methodological approach was based on qualitative interviews with 34 formal and informal workers. The findings show how workers perceive informal employment as negatively affecting their mental and physical health through different dimensions of their living and working conditions. Incorporating a gender perspective proves to be integral to the analysis of these processes. The article concludes by discussing how neoliberalism underlies such vulnerability processes and negatively impacts on the population's health.

Corporate influenced state preemption and health: A legal mapping analysis of workers' rights preemption bills in the US south

Work is a structural determinant of health. As local governments have taken the lead on implementing workers' rights policies, state governments have increasingly been using preemption to block local them. These policies would improve work and employment conditions, particularly for Black, Brown, immigrant, and low-wage workers. Thus, preemption of workers' right policies is an important health equity issue. Legal epidemiology methods were used to analyze and quantify worker's rights preemption bills introduced in southern state legislatures between 2009 and 2019. Between 2009 and 2019, over 100 workers' rights preemption bills were introduced in southern state legislatures, and there was significant variation between states. Preemption of local paid leave and minimum wage ordinances were the most common. Textual analysis of the bills revealed that states prioritize the perspectives of employers instead of workers. State labor policies are prioritizing the perspectives of businesses over workers resulting in a labor environment that creates structural advantages for employers and is hostile to the well-being of workers. Preemption is part of the political and social context that is shaping the association between work and health in and is likely re (creating) racial and economic inequities.

Early retirement intentions: the impact of employment biographies, work stress and health among a baby-boomer generation

In recent years, early retirement decisions have become more frequent in the European Union despite political efforts to prevent early retirement. This is a growing problem for the social security system. The study focuses on a life course approach using employment biographies and investigates the influence of work stress and health on early retirement intentions. Data of employees who were born in either 1959 or 1965 of the German cohort study on work, age, health and work participation are analysed (n = 3338). By linking survey and register data from 1993 to 2011, a sequence analysis is conducted to identify employment biographies. To analyse the relationship between the employment biographies and intended early retirement, a longitudinal path analysis is computed and includes work stress, measured through effort-reward imbalance, and self-rated health. The statistical analyses identify three adverse employment biographies, i.e. part-time work, episodes of unemployment or marginal employment. In addition, two favourable employment biographies are determined, characterised by full-time work and few episodes of unemployment. The results of the path analysis show that employment biographies with high work-related stress have early retirement intentions. Among adverse employment biographies, indirect effects of poor health on the association between work stress and early retirement intentions are found. Unexpectedly, among full-time workers, work stress is also associated with early retirement intentions with an additional mediation through health. The findings of this study highlight the importance of the life course perspective when analysing retirement decisions. In addition to health-promoting interventions in the labour market, effects of psychosocial factors should be focussed on in order to reduce early exits from the labour market.

Mental and social wellbeing and the UK coronavirus job retention scheme: Evidence from nine longitudinal studies

BACKGROUND

The COVID-19 pandemic has led to major economic disruptions. In March 2020, the UK implemented the Coronavirus Job Retention Scheme - known as furlough - to minimize the impact of job losses. We investigate associations between change in employment status and mental and social wellbeing during the early stages of the pandemic.

METHODS

Data were from 25,670 respondents, aged 17-66, across nine UK longitudinal studies. Furlough and other employment changes were defined using employment status pre-pandemic and during the first lockdown (April-June 2020). Mental and social wellbeing outcomes included psychological distress, life satisfaction, self-rated health, social contact, and loneliness. Study-specific modified Poisson regression estimates, adjusting for socio-demographic characteristics and pre-pandemic mental and social wellbeing, were pooled using meta-analysis. Associations were also stratified by sex, age, education, and household composition.

RESULTS

Compared to those who remained working, furloughed workers were at greater risk of psychological distress (adjusted risk ratio, ARR = 1.12; 95%CI: 0.97, 1.29), low life satisfaction (ARR = 1.14; 95%CI: 1.07, 1.22), loneliness (ARR = 1.12; 95%CI: 1.01, 1.23), and poor self-rated health (ARR = 1.26; 95%CI: 1.05, 1.50). Nevertheless, compared to furloughed workers, those who became unemployed had greater risk of psychological distress (ARR = 1.30; 95%CI: 1.12, 1.52), low life satisfaction (ARR = 1.16; 95%CI: 0.98, 1.38), and loneliness (ARR = 1.67; 95%CI: 1.08, 2.59). Effects were not uniform across all sub-groups.

CONCLUSIONS

During the early stages of the pandemic, those furloughed had increased risk of poor mental and social wellbeing, but furloughed workers fared better than those who became unemployed, suggesting that furlough may have partly mitigated poorer outcomes.

Building a better understanding of labour exploitation's impact on migrant health: An operational framework

Background

There is limited evidence on labour exploitation’s impact on migrant health. This population is, however, often employed in manual low-skilled jobs known for poor labour conditions and exploitation risks. The lack of a common conceptualisation of labour exploitation in health research impedes the development of research measuring its effects on migrant health and, ultimately, our understanding of migrants’ health needs.

Aim

To develop an operational conceptual framework of labour exploitation focusing on migrant workers in manual low-skilled jobs.

Methods

Non-probabilistic sampling was used to recruit multidisciplinary experts on labour exploitation. An online Group Concept Mapping (GCM) was conducted. Experts: 1) generated statements describing the concept ‘labour exploitation’ focusing on migrants working in manual low-skilled jobs; 2) sorted generated statements into groups reflecting common themes; and 3) rated them according to their importance in characterising a situation as migrant labour exploitation. Multidimensional Scaling and Cluster Analysis were used to produce an operational framework detailing the concept content (dimensions, statements, and corresponding averaged rating).

Findings

Thirty-two experts sorted and rated 96 statements according to their relative importance (1 “relatively unimportant” to 5 “extremely important”). The operational framework consists of four key dimensions of migrant labour exploitation, distributed along a continuum of severity revealed by the rating: ‘Shelter and personal security’ (rating: 4.47); ‘Finance and migration’ (4.15); ‘Health and safety’ (3.96); and ‘Social and legal protection’ (3.71).

Conclusion

This study is the first to both generate an empirical operational framework of migrant labour exploitation, and demonstrate the existence of a "continuum from decent work to forced labour". The framework content can be operationalised to measure labour exploitation. It paves the way to better understand how different levels of exploitation affect migrant workers’ health for global policymakers, health researchers, and professionals working in the field of migrant exploitation.

Unconditional cash transfers for reducing poverty and vulnerabilities: effect on use of health services and health outcomes in low- and middle-income countries

BACKGROUND

Unconditional cash transfers (UCTs; provided without obligation) for reducing poverty and vulnerabilities (e.g. orphanhood, old age, or HIV infection) are a social protection intervention addressing a key social determinant of health (income) in low- and middle-income countries (LMICs). The relative effectiveness of UCTs compared with conditional cash transfers (CCTs; provided only if recipients follow prescribed behaviours, e.g. use a health service or attend school) is unknown.

OBJECTIVES

To assess the effects of UCTs on health services use and health outcomes in children and adults in LMICs. Secondary objectives are to assess the effects of UCTs on social determinants of health and healthcare expenditure, and to compare the effects of UCTs versus CCTs.

SEARCH METHODS

For this update, we searched 15 electronic academic databases, including CENTRAL, MEDLINE and EconLit, in September 2021. We also searched four electronic grey literature databases, websites of key organisations and reference lists of previous systematic reviews, key journals and included study records.

SELECTION CRITERIA

We included both parallel-group and cluster-randomised controlled trials (C-RCTs), quasi-RCTs, cohort studies, controlled before-and-after studies (CBAs), and interrupted time series studies of UCT interventions in children (0 to 17 years) and adults (≥ 18 years) in LMICs. Comparison groups received either no UCT, a smaller UCT or a CCT. Our primary outcomes were any health services use or health outcome.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened potentially relevant records for inclusion, extracted data and assessed the risk of bias. We obtained missing data from study authors if feasible. For C-RCTs, we generally calculated risk ratios for dichotomous outcomes from crude frequency measures in approximately correct analyses. Meta-analyses applied the inverse variance or Mantel-Haenszel method using a random-effects model. Where meta-analysis was impossible, we synthesised results using vote counting based on effect direction. We assessed the certainty of the evidence using GRADE.

MAIN RESULTS

We included 34 studies (25 studies of 20 C-RCTs, six CBAs, and three cohort studies) involving 1,140,385 participants (45,538 children, 1,094,847 adults) and 50,095 households in Africa, the Americas and South-East Asia in our meta-analyses and narrative syntheses. These analysed 29 independent data sets. The 24 UCTs identified, including one basic universal income intervention, were pilot or established government programmes or research experiments. The cash value was equivalent to 1.3% to 81.9% of the annualised gross domestic product per capita. All studies compared a UCT with no UCT; three studies also compared a UCT with a CCT. Most studies carried an overall high risk of bias (i.e. often selection or performance bias, or both). Most studies were funded by national governments or international organisations, or both. Throughout the review, we use the words 'probably' to indicate moderate-certainty evidence, 'may/maybe' for low-certainty evidence, and 'uncertain' for very low-certainty evidence. Health services use We assumed greater use of any health services to be beneficial. UCTs may not have impacted the likelihood of having used any health service in the previous 1 to 12 months, when participants were followed up between 12 and 24 months into the intervention (risk ratio (RR) 1.04, 95% confidence interval (CI) 1.00 to 1.09; I² = 2%; 5 C-RCTs, 4972 participants; low-certainty evidence). Health outcomes At one to two years, UCTs probably led to a clinically meaningful, very large reduction in the likelihood of having had any illness in the previous two weeks to three months (RR 0.79, 95% CI 0.67 to 0.92; I² = 53%; 6 C-RCTs, 9367 participants; moderate-certainty evidence). UCTs may have increased the likelihood of having been food secure over the previous month, at 13 to 36 months into the intervention (RR 1.25, 95% CI 1.09 to 1.45; I² = 85%; 5 C-RCTs, 2687 participants; low-certainty evidence). UCTs may have increased participants' level of dietary diversity over the previous week, when assessed with the Household Dietary Diversity Score and followed up 24 months into the intervention (mean difference (MD) 0.59 food categories, 95% CI 0.18 to 1.01; I² = 79%; 4 C-RCTs, 9347 participants; low-certainty evidence). Despite several studies providing relevant evidence, the effects of UCTs on the likelihood of being moderately stunted and on the level of depression remain uncertain. We found no study on the effect of UCTs on mortality risk. Social determinants of health UCTs probably led to a clinically meaningful, moderate increase in the likelihood of currently attending school, when assessed at 12 to 24 months into the intervention (RR 1.06, 95% CI 1.04 to 1.09; I² = 0%; 8 C-RCTs, 7136 participants; moderate-certainty evidence). UCTs may have reduced the likelihood of households being extremely poor, at 12 to 36 months into the intervention (RR 0.92, 95% CI 0.87 to 0.97; I² = 63%; 6 C-RCTs, 3805 participants; low-certainty evidence). The evidence was uncertain for whether UCTs impacted livestock ownership, participation in labour, and parenting quality. Healthcare expenditure Evidence from eight cluster-RCTs on healthcare expenditure was too inconsistent to be combined in a meta-analysis, but it suggested that UCTs may have increased the amount of money spent on health care at 7 to 36 months into the intervention (low-certainty evidence). Equity, harms and comparison with CCTs The effects of UCTs on health equity (or unfair and remedial health inequalities) were very uncertain. We did not identify any harms from UCTs. Three cluster-RCTs compared UCTs versus CCTs with regard to the likelihood of having used any health services or had any illness, or the level of dietary diversity, but evidence was limited to one study per outcome and was very uncertain for all three.

AUTHORS' CONCLUSIONS

This body of evidence suggests that unconditional cash transfers (UCTs) may not impact a summary measure of health service use in children and adults in LMICs. However, UCTs probably or may improve some health outcomes (i.e. the likelihood of having had any illness, the likelihood of having been food secure, and the level of dietary diversity), two social determinants of health (i.e. the likelihoods of attending school and being extremely poor), and healthcare expenditure. The evidence on the relative effectiveness of UCTs and CCTs remains very uncertain.

Community Resident Perceptions of and Experiences with Precarious Work at the Neighborhood Level: The Greater Lawndale Healthy Work Project

Work is a key social determinant of health. Community health and well-being may be impacted in neighborhoods with high proportions of people engaged in precarious work situations compounded by health inequities produced by other social determinants associated with their residential geography. However, little is known about how community residents experience work at the neighborhood level nor how work impacts health at the community-level, particularly in communities with a high proportion of residents engaged in precarious work. We sought to understand, through participatory research strategies, how work is experienced at the community level and to identify community interventions to establish a culture of healthy work. As part of a mixed-methods community health assessment, community researchers conducted focus groups with residents in two high social and economic hardship neighborhoods on Chicago’s southwest side. Community and academic researchers engaged in participatory data analysis and developed and implemented member-checking modules to engage residents in the data interpretation process. Twelve focus group discussions (77 community resident participants) were completed. Three major themes emerged: systematic marginalization from the pathways to healthy work situations; contextual and structural hostility to sustain healthy work; and violations in the rights, agency, and autonomy of resident workers. Findings were triangulated with findings from the concept-mapping research component of the project to inform the development of a community health survey focused on work characteristics and experiences. Listening to residents in communities with a high proportion of residents engaging in precarious work allows for the identification of nuanced community-informed intervention points to begin to build a culture of healthy work.

The impact of Active Labour Market Policies on health outcomes: a Scoping review

BACKGROUND

Since the last Western great recession of 2008, an increasing interest on the effects of Active Labour Market Policies (ALMPs) on improving health has emerged. The aim of our review is to synthesize evidence on the effectiveness of ALMPs and whether some types of ALMP are more effective.

METHODS

Using the Scoping review methodology, we conducted a literature review in PubMed/MEDLINE, Scopus and Web of Science and selected articles published between 1990 and 2017 in high income countries. We applied four sequential phases of document screening to the list of retrieved articles.

RESULTS

Of the 416 documents detected in the search, 36 documents were finally selected. Most of them focused on mental health and related components (72.2%) and found positive results at least in one outcome (80.6%). The ALMPs reported mainly attempt to build capacity through job search assistance (31.6%) with a component on mental health, showing positive results on health; some offer job training (16.7%) and few subsidized employment (8.3%), showing more controversial results, although mostly positive. The rest include a combination of different types of ALMPs.

CONCLUSIONS

This review shows that ALMPs have a positive impact on health and quality of life. There are relatively few studies of the impact of ALMPs on general health, and most of the studies found are focused on Anglo-Saxon and Nordic countries. The most significant knowledge gaps are the mechanisms involved in achieving this improvement, and above all the differential health impacts according to axes of inequality and welfare state.

Decent Work, ILO's Response to the Globalization of Working Life: Basic Concepts and Global Implementation with Special Reference to Occupational Health

Twenty years ago, the International Labour Organization (ILO) launched a new strategy, the Decent Work Agenda, to ensure human-oriented development in the globalization of working life and to provide an effective response to the challenges of globalization. We searched for and analysed the origin of the Decent Work concept and identified the key principles in ILO policy documents, survey reports, and relevant United Nations’ (UN) documents. We also analysed the implementation of the Decent Work Country Programmes (DWCPs) and examined the available external evaluation reports. Finally, we examined the objectives of the ILO Decent Work Agenda and the Decent Work targets in the UN 2030 Agenda for Sustainable Development in view of occupational health. In two thirds of the ILO’s Member States, the Decent Work Agenda has been successfully introduced and so far fully or partly implemented in their DWCPs. The sustainability of the Decent Work approach was ensured through the UN 2030 Agenda, the ILO Global Commission Report on the Future of Work, and the ILO Centenary Declaration. However, objectives in line with the ILO Convention No. 161 on Occupational Health Services were not found in the DWCPs. Although successful in numerous aspects in terms of the achievement of the Decent Work objectives and the UN Sustainable Development Goals (SDGs), the Decent Work Agenda and the Decent Work Country Programmes need further development and inclusion of the necessary strategies, objectives, and actions for occupational health services, particularly in view of the high burden of work-related diseases and, for example, the present global pandemic. In many countries, national capabilities for participation and implementation of Decent Work Country Programmes need strengthening.

Unravelling Hidden Informal Employment in Chile: Towards a New Classification and Measurements to Study Its Public Health Impact

This study aims to assess differences in the working population of Chile under the definition of informal employment. A new categorization of informal employment is proposed, with a focus on social protection as a key element in the definition of informal employment status, thereby making visible different groups of workers that until now remained hidden. From a mixed methodological strategy that combines literature review, key informant interviews, and quantitative data analysis, the researchers seek to understand the complexity of the social phenomenon of informality.

Health inequalities and health equity challenges for victims of modern slavery

Background

Modern slavery is a serious organized crime, with severe consequences for the physical and mental health of victims, and so has public health implications. Anecdotally many victims of sex slavery experience difficulties accessing healthcare. Public Health England recently articulated the importance of health engagement to address modern slavery but little is known about the experiences of the survivors.

Methods

We conducted in depth interviews with Albanian female survivors of sex slavery who all displayed significant and complex health needs. Interviews were conducted between July 2017 and January 2018. Thematic analysis identified four primary themes: (i) barriers to access, (ii) negotiating access, (iii) health needs and care received and (iv) overall experience of primary care.

Results

Survivors experienced repeated challenges accessing healthcare, for themselves and their children, and initially could not access GP services. When accompanied by an advocate they reported qualitatively and quantitatively improved experiences resulting in improved permeability. Confusion surrounding eligibility criteria and a lack of understanding of modern slavery emerged as the primary barriers, fueling biased adjudications.

Conclusions

The importance of advocates, enabling rights-based approaches, improving understanding about access to health services for vulnerable groups, and a need for education across health service settings are discussed.

Unconditional cash transfers for reducing poverty and vulnerabilities: effect on use of health services and health outcomes in low- and middle-income countries

BACKGROUND

Unconditional cash transfers (UCTs; provided without obligation) for reducing poverty and vulnerabilities (e.g. orphanhood, old age or HIV infection) are a type of social protection intervention that addresses a key social determinant of health (income) in low- and middle-income countries (LMICs). The relative effectiveness of UCTs compared with conditional cash transfers (CCTs; provided so long as the recipient engages in prescribed behaviours such as using a health service or attending school) is unknown.

OBJECTIVES

To assess the effects of UCTs for improving health services use and health outcomes in vulnerable children and adults in LMICs. Secondary objectives are to assess the effects of UCTs on social determinants of health and healthcare expenditure and to compare to effects of UCTs versus CCTs.

SEARCH METHODS

We searched 17 electronic academic databases, including the Cochrane Public Health Group Specialised Register, the Cochrane Database of Systematic Reviews (the Cochrane Library 2017, Issue 5), MEDLINE and Embase, in May 2017. We also searched six electronic grey literature databases and websites of key organisations, handsearched key journals and included records, and sought expert advice.

SELECTION CRITERIA

We included both parallel group and cluster-randomised controlled trials (RCTs), quasi-RCTs, cohort and controlled before-and-after (CBAs) studies, and interrupted time series studies of UCT interventions in children (0 to 17 years) and adults (18 years or older) in LMICs. Comparison groups received either no UCT or a smaller UCT. Our primary outcomes were any health services use or health outcome.

DATA COLLECTION AND ANALYSIS

Two reviewers independently screened potentially relevant records for inclusion criteria, extracted data and assessed the risk of bias. We tried to obtain missing data from study authors if feasible. For cluster-RCTs, we generally calculated risk ratios for dichotomous outcomes from crude frequency measures in approximately correct analyses. Meta-analyses applied the inverse variance or Mantel-Haenszel method with random effects. We assessed the quality of evidence using the GRADE approach.

MAIN RESULTS

We included 21 studies (16 cluster-RCTs, 4 CBAs and 1 cohort study) involving 1,092,877 participants (36,068 children and 1,056,809 adults) and 31,865 households in Africa, the Americas and South-East Asia in our meta-analyses and narrative synthesis. The 17 types of UCTs we identified, including one basic universal income intervention, were pilot or established government programmes or research experiments. The cash value was equivalent to 1.3% to 53.9% of the annualised gross domestic product per capita. All studies compared a UCT with no UCT, and three studies also compared a UCT with a CCT. Most studies carried an overall high risk of bias (i.e. often selection and/or performance bias). Most studies were funded by national governments and/or international organisations.Throughout the review, we use the words 'probably' to indicate moderate-quality evidence, 'may/maybe' for low-quality evidence, and 'uncertain' for very low-quality evidence. UCTs may not have impacted the likelihood of having used any health service in the previous 1 to 12 months, when participants were followed up between 12 and 24 months into the intervention (risk ratio (RR) 1.04, 95% confidence interval (CI) 1.00 to 1.09, P = 0.07, 5 cluster-RCTs, N = 4972, I² = 2%, low-quality evidence). At one to two years, UCTs probably led to a clinically meaningful, very large reduction in the likelihood of having had any illness in the previous two weeks to three months (odds ratio (OR) 0.73, 95% CI 0.57 to 0.93, 5 cluster-RCTs, N = 8446, I² = 57%, moderate-quality evidence). Evidence from five cluster-RCTs on food security was too inconsistent to be combined in a meta-analysis, but it suggested that at 13 to 24 months' follow-up, UCTs could increase the likelihood of having been food secure over the previous month (low-quality evidence). UCTs may have increased participants' level of dietary diversity over the previous week, when assessed with the Household Dietary Diversity Score and followed up 24 months into the intervention (mean difference (MD) 0.59 food categories, 95% CI 0.18 to 1.01, 4 cluster-RCTs, N = 9347, I² = 79%, low-quality evidence). Despite several studies providing relevant evidence, the effects of UCTs on the likelihood of being moderately stunted and on the level of depression remain uncertain. No evidence was available on the effect of a UCT on the likelihood of having died. UCTs probably led to a clinically meaningful, moderate increase in the likelihood of currently attending school, when assessed at 12 to 24 months into the intervention (RR 1.06, 95% CI 1.03 to 1.09, 6 cluster-RCTs, N = 4800, I² = 0%, moderate-quality evidence). The evidence was uncertain for whether UCTs impacted livestock ownership, extreme poverty, participation in child labour, adult employment or parenting quality. Evidence from six cluster-RCTs on healthcare expenditure was too inconsistent to be combined in a meta-analysis, but it suggested that UCTs may have increased the amount of money spent on health care at 7 to 24 months into the intervention (low-quality evidence). The effects of UCTs on health equity (or unfair and remedial health inequalities) were very uncertain. We did not identify any harms from UCTs. Three cluster-RCTs compared UCTs versus CCTs with regard to the likelihood of having used any health services, the likelihood of having had any illness or the level of dietary diversity, but evidence was limited to one study per outcome and was very uncertain for all three.

This body of evidence suggests that unconditional cash transfers (UCTs) may not impact a summary measure of health service use in children and adults in LMICs. However, UCTs probably or may improve some health outcomes (i.e. the likelihood of having had any illness, the likelihood of having been food secure, and the level of dietary diversity), one social determinant of health (i.e. the likelihood of attending school), and healthcare expenditure. The evidence on the relative effectiveness of UCTs and CCTs remains very uncertain.

Informal employment in high-income countries for a health inequalities research: A scoping review

BACKGROUND

Informal employment (IE) is one of the least studied employment conditions in public health research, mainly due to the difficulty of its conceptualization and its measurement, producing a lack of a unique concept and a common method of measurement.

OBJECTIVE

The aim of this review is to identify literature on IE in order to improve its definition and methods of measurement, with special attention given to high-income countries, to be able to study the possible impact on health inequalities within and between countries.

METHODS

A scoping review of definitions and methods of measurement of IE was conducted reviewing relevant databases and grey literature and analyzing selected articles.

RESULTS

We found a wide spectrum of terms for describing IE as well as definitions and methods of measurement. We provide a definition of IE to be used in health inequalities research in high-income countries. Direct methods such as surveys can capture more information about workers and firms in order to estimate IE.

CONCLUSIONS

These results can be used in further investigations about the impacts of this IE on health inequalities. Public health research must improve monitoring and analysis of IE in order to know the impacts of this employment condition on health inequalities.

Mental health and migration: depression, alcohol abuse, and access to health care among migrants in Central Asia

One-fifth of Kazakhstan's population is labor migrants working in poor conditions with limited legal rights. This paper examines self-rated health, mental health and access to health care among migrant workers. Using geo-mapping, a random sample of internal and external migrant market workers was selected in Almaty (N = 450). We used survey logistic regression adjusted for clustering of workers within stalls. Almost half of participants described their health as fair or poor and reported not seeing a doctor when needed, 6.2% had clinical depression and 8.7% met criteria for alcohol abuse. Female external migrants were at higher risk for poor health and underutilization of health services. High mobility was associated with depression among internal migrants and with alcohol abuse among female migrant workers. This study demonstrates the urgent need to address health and mental health needs and improve access to health care among labor migrants in Central Asia.

Unconditional cash transfers for assistance in humanitarian disasters: effect on use of health services and health outcomes in low- and middle-income countries

BACKGROUND

Unconditional cash transfers (UCTs) are a common social protection intervention that increases income, a key social determinant of health, in disaster contexts in low- and middle-income countries (LMICs).

OBJECTIVES

To assess the effects of UCTs in improving health services use, health outcomes, social determinants of health, health care expenditure, and local markets and infrastructure in LMICs. We also compared the relative effectiveness of UCTs delivered in-hand with in-kind transfers, conditional cash transfers, and UCTs paid through other mechanisms.

SEARCH METHODS

We searched 17 academic databases, including the Cochrane Public Health Group Specialised Register, the Cochrane Database of Systematic Reviews (The Cochrane Library 2014, Issue 7), MEDLINE, and EMBASE between May and July 2014 for any records published up until 4 May 2014. We also searched grey literature databases, organisational websites, reference lists of included records, and academic journals, as well as seeking expert advice.

SELECTION CRITERIA

We included randomised and quasi-randomised controlled trials (RCTs), as well as cohort, interrupted time series, and controlled before-and-after studies (CBAs) on UCTs in LMICs. Primary outcomes were the use of health services and health outcomes.

DATA COLLECTION AND ANALYSIS

Two authors independently screened all potentially relevant records for inclusion criteria, extracted the data, and assessed the included studies' risk of bias. We requested missing information from the study authors.

MAIN RESULTS

Three studies (one cluster-RCT and two CBAs) comprising a total of 13,885 participants (9640 children and 4245 adults) as well as 1200 households in two LMICs (Nicaragua and Niger) met the inclusion criteria. They examined five UCTs between USD 145 and USD 250 (or more, depending on household characteristics) that were provided by governmental, non-governmental or research organisations during experiments or pilot programmes in response to droughts. Two studies examined the effectiveness of UCTs, and one study examined the relative effectiveness of in-hand UCTs compared with in-kind transfers and UCTs paid via mobile phone. Due to the methodologic limitations of the retrieved records, which carried a high risk of bias and very serious indirectness, we considered the body of evidence to be of very low overall quality and thus very uncertain across all outcomes.Depending on the specific health services use and health outcomes examined, the included studies either reported no evidence that UCTs had impacted the outcome, or they reported that UCTs improved the outcome. No single outcome was reported by more than one study. There was a very small increase in the proportion of children who received vitamin or iron supplements (mean difference (MD) 0.10 standard deviations (SDs), 95% confidence interval (CI) 0.06 to 0.14) and on the child's home environment, as well as clinically meaningful, very large reductions in the chance of child death (hazard ratio (HR) 0.26, 95% CI 0.10 to 0.66) and the incidence of severe acute malnutrition (HR 0.44, 95% CI 0.24 to 0.80). There was also a moderate reduction in the number of days children spent sick in bed (MD - 0.36 SDs, 95% CI - 0.62 to - 0.10). There was no evidence for any effect on the proportion of children receiving deworming drugs, height for age among children, adults' level of depression, or the quality of parenting behaviour. No adverse effects were identified. The included comparisons did not examine several important outcomes, including food security and equity impacts.With regard to the relative effectiveness of UCTs compared with a food transfer providing a relatively high total caloric value, there was no evidence that a UCT had any effect on the chance of child death (HR 2.27, 95% CI 0.69 to 7.44) or severe acute malnutrition (HR 1.15, 95% CI 0.67 to 1.99). A UCT paid in-hand led to a clinically meaningful, moderate increase in the household dietary diversity score, compared with the same UCT paid via mobile phone (difference-in-differences estimator 0.43 scores, 95% CI 0.06 to 0.80), but there was no evidence for an effect on social determinants of health, health service expenditure, or local markets and infrastructure.

AUTHORS' CONCLUSIONS

Additional high-quality evidence (especially RCTs of humanitarian disaster contexts other than droughts) is required to reach clear conclusions regarding the effectiveness and relative effectiveness of UCTs for improving health services use and health outcomes in humanitarian disasters in LMICs.

Socioeconomic indicators of health inequalities and female mortality: a nested cohort study within the United Kingdom Collaborative Trial of Ovarian Cancer Screening (UKCTOCS)

Background

Evidence is mounting that area-level socioeconomic indicators are important tools for predicting health outcomes. However, few studies have examined these alongside individual-level education. This nested cohort study within the control arm of the United Kingdom Collaborative Trial of Ovarian Cancer Screening (UKCTOCS) assesses the association of mutually adjusted individual (education) and area-level (Index of Multiple Deprivation-IMD 2007) socioeconomic status indicators and all-cause female mortality.

Methods

Participants resident in England who had completed both baseline (Wave 1) and follow up (Wave 2) questionnaires were included. Follow-up was through the Health and Social Care Information Centre with deaths censored on 31st December 2012. IMD, education and a range of covariates were explored. Cox regression models adjusted for all covariates were used. Sensitivity analysis using imputation was performed (1) including those with missing data and (2) on the entire cohort who had completed the baseline questionnaire.

Results

Of the 54,539 women resident in England who completed both Wave 1 and Wave 2 questionnaires, 4,510 had missing data. The remaining 50,029 women were included in the primary analysis. Area-level IMD was positively associated with all-cause mortality for the most deprived group compared to the least deprived (HR=1.42, CI=1.14-1.78) after adjusting for all potential confounders. Sensitivity analyses showed similar results with stronger associations in the entire cohort (HR=1.90, CI=1.68-2.16). The less educated an individual, the higher the mortality risk (test for trend p=<0.001). However, the crude effect on mortality of having no formal education compared to college/university education disappeared when adjusted for IMD rank (HR=1.08, CI=0.93-1.26).

Conclusion

Women living in more deprived areas continue to have higher mortality even in this less deprived cohort and after adjustment for a range of potential confounders.

The effect of leaving employment on mental health: testing 'adaptation' versus 'sensitisation' in a cohort of working-age Australians

OBJECTIVES

To investigate the 'adaptation' versus 'sensitisation' hypotheses in relation to mental health and labour market transitions out of employment to determine whether mental health stabilised (adaptation) or worsened (sensitisation) as people experienced one or more periods without work.

METHODS

The Household Income and Labour Dynamics of Australia (HILDA) longitudinal survey was used to investigate the relationship between the number of times a person had been unemployed or had periods out of the labour force (ie, spells without work) and the Mental Component Summary (MCS) of the Short Form 36 (SF-36). Demographic, health and employment related confounders were included in a series of multilevel regression models.

RESULTS

During 2001-2010, 3362 people shifted into unemployment and 1105 shifted from employment to not in the labour force. Compared with participants who did not shift, there was a 1.64-point decline (95% CI -2.05 to -1.23, p<0.001) in scores of the MCS SF-36 among those who had one spell of unemployment (excluding not in the labour force), and a 2.56-point decline (95% CI -3.93 to -1.19, p<0.001) among those who had two or more spells of unemployment after adjusting for other variables. Findings for shifts from employment to 'not in the labour force' were in the same direction; however, effect sizes were smaller.

CONCLUSIONS

These results indicate that multiple spells of unemployment are associated with continued, though small, declines in mental health. Those who leave employment for reasons other than unemployment experience a smaller reduction in mental health.

In-work tax credits for families and their impact on health status in adults

BACKGROUND

By improving two social determinants of health (poverty and unemployment) in low- and middle-income families on or at risk of welfare, in-work tax credit for families (IWTC) interventions could impact health status and outcomes in adults.

OBJECTIVES

To assess the effects of IWTCs on health outcomes in working-age adults (18 to 64 years).

SEARCH METHODS

We searched 16 electronic academic databases, including the Cochrane Public Health Group Specialised Register, Cochrane Database of Systematic Reviews (The Cochrane Library 2012, Issue 7), MEDLINE and EMBASE, as well as six grey literature databases between July and September 2012 for records published between January 1980 and July 2012. We also searched key organisational websites, handsearched reference lists of included records and relevant journals, and contacted academic experts.

SELECTION CRITERIA

We included randomised and quasi-randomised controlled trials and cohort, controlled before-and-after (CBA) and interrupted time series (ITS) studies of IWTCs in working-age adults. Included primary outcomes were: self rated general health; mental health/psychological distress; mental illness; overweight/obesity; alcohol use and tobacco use.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed the risk of bias in included studies. We contacted study authors to obtain missing information.

MAIN RESULTS

Five studies (one CBA and four ITS) comprising a total of 5,677,383 participants (all women) fulfilled the inclusion criteria and were synthesised narratively. The in-work tax credit intervention assessed in all included studies is the permanent Earned Income Tax Credit in the United States, established in 1975. This intervention distributed nearly USD 62 billion to over 27 million individuals in 2011, and its administration costs were less than one per cent of its total costs. All included studies carried a high risk of bias (especially from confounding and insufficient control for underlying time trends). Due to the small number of (observational) studies and their high risk of bias, we judged this body of evidence to have very low overall quality.One study found that IWTC had no detectable effect on self rated general health and mental health/psychological distress five years after its implementation (i.e. a considerable change in the generosity of the permanent IWTC) and on overweight/obesity eight years after implementation. One study found no effect of IWTC on tobacco use five years after implementation, one a moderate reduction in tobacco use one year after implementation (odds ratio 0.95, 95% confidence interval (CI) 0.94 to 0.96), and one differential effects, with no effect in African-Americans and a large reduction in European-Americans two years after implementation (risk difference -11.1%, 95% CI -20.9% to -1.3%). No evidence was available for the effect of IWTC on mental illness and alcohol use. No adverse effects of IWTC were identified.One study also found no detectable effect of IWTC on the number of bad physical health days and of risky biomarkers for inflammation, cardiovascular disease and metabolic conditions eight years after implementation. One study found that IWTC had a large, positive effect on income from wages or salaries one year after implementation. Two studies found no effect on employment two and five years after implementation, whereas two found a moderate increase five and eight years after implementation and one a large increase in employment due to IWTC one year after implementation.No differences in outcomes between groups with different educational status were found for self rated health and mental health/psychological distress. In one study European-American women with lower levels of education were more likely to reduce tobacco use, while tobacco use did not change among African-American women with lower levels of education. However, no differences in tobacco use by educational status were observed in a second study. Two studies found that the intervention may have reduced inequity with respect to employment, where women with less education were more likely to move into employment (although one did not establish whether this difference was statistically significant), while two studies found no such difference and no studies found differences by ethnic group on employment rates.

AUTHORS' CONCLUSIONS

In summary, the small and methodologically limited existing body of evidence with a high risk of bias provides no evidence for an effect of in-work tax credit for families interventions on health status (except for mixed evidence for tobacco smoking) in adults.

Gender inequalities in occupational health related to the unequal distribution of working and employment conditions: a systematic review

Introduction

Gender inequalities exist in work life, but little is known about their presence in relation to factors examined in occupation health settings. The aim of this study was to identify and summarize the working and employment conditions described as determinants of gender inequalities in occupational health in studies related to occupational health published between 1999 and 2010.

Methods

A systematic literature review was undertaken of studies available in MEDLINE, EMBASE, Sociological Abstracts, LILACS, EconLit and CINAHL between 1999 and 2010. Epidemiologic studies were selected by applying a set of inclusion criteria to the title, abstract, and complete text. The quality of the studies was also assessed. Selected studies were qualitatively analysed, resulting in a compilation of all differences between women and men in the prevalence of exposure to working and employment conditions and work-related health problems as outcomes.

Results

Most of the 30 studies included were conducted in Europe (n=19) and had a cross-sectional design (n=24). The most common topic analysed was related to the exposure to work-related psychosocial hazards (n=8). Employed women had more job insecurity, lower control, worse contractual working conditions and poorer self-perceived physical and mental health than men did. Conversely, employed men had a higher degree of physically demanding work, lower support, higher levels of effort-reward imbalance, higher job status, were more exposed to noise and worked longer hours than women did.

Conclusions

This systematic review has identified a set of working and employment conditions as determinants of gender inequalities in occupational health from the occupational health literature. These results may be useful to policy makers seeking to reduce gender inequalities in occupational health, and to researchers wishing to analyse these determinants in greater depth.

Complementarities or Contradictions? Scoping the Health Dimensions of “Flexicurity” Labor Market Policies

Flexicurity, or the integration of labor market flexibility with social security and active labor market policies, has figured prominently in economic and social policy discussions in Europe since the mid-1990s. Such policies are designed to transcend traditional labor-capital conflicts and to form a mutually supportive nexus of flexibility and security within a climate of intensified competition and rapid technological change. International bodies have marketed flexicurity as an innovative win-win strategy for employers and workers alike, commonly citing Denmark and the Netherlands as exemplars of best practice. In this article, we apply a social determinants of health framework to conduct a scoping review of the academic and gray literature to: ( a) better understand the empirical associations between flexicurity practices and population health in Denmark and ( b) assess the relevance and feasibility of implementing such policies to improve health and reduce health inequalities in Ontario, Canada. Based on 39 studies meeting our full inclusion criteria, preliminary findings suggest that flexicurity is limited as a potential health promotion strategy in Ontario, offers more risks to workers' health than benefits, and requires the strengthening of other social protections before it could be realistically implemented within a Canadian context.

The association between nonstandard work and occupational injury in Korea

BACKGROUND

The number of workers who died due to occupational injury in Korea as of 2007 was 1,383. The aim of this study was to identify whether there were any differences in the risk of occupational injury between nonstandard workers (temporary workers and/or subcontract workers) and regular workers.

METHODS

1,576 injured workers, selected from National Health Insurance and National Workers' Compensation Insurance, were interviewed via telephone survey using standardized questionnaires in 2007. The control group was 1,500 workers matched for age, gender, and severity of injury. A multivariate logistic regression model was used to analyze the association between the type of nonstandard work and occupational injury.

RESULTS

Nonstandard temporary workers were more likely to be injured than regular workers even if other related factors of occupational injury were statistically adjusted (adjusted odds ratio, OR 2.87, 95% confidence interval 2.37-3.49).

CONCLUSIONS

The reason why the risks of nonstandard workers are higher than those of regular workers is that nonstandard workers are placed in poor working conditions.

[Gender inequalities in occupational health in Spain]

OBJECTIVES

To analyze gender inequalities in employment and working conditions, the work-life balance, and work-related health problems in a sample of the employed population in Spain in 2007, taking into account social class and the economic sector.

METHODS

Gender inequalities were analyzed by applying 25 indicators to the 11,054 workers interviewed for the VI edition of the National Working Conditions Survey. Multivariate logistic regression models were used to calculate odds ratios (OR) and 95% confidence intervals (95% CI), stratifying by occupational social class and economic sector.

RESULTS

More women than men worked without a contract (OR=1.83; 95% CI: 1.51-2.21) and under high-effort/low-reward conditions (1.14:1.05-1.25). Women also experienced more sexual harassment (2.85:1.75-4.62), discrimination (1.60:1.26-2.03) and musculoskeletal pain (1.38:1.19-1.59). More men than women carried out shift work (0.86:0.79-0.94), with high noise levels (0.34:0.30-0.40), and high physical demands (0.58:0.54-0.63). Men also suffered more injuries due to occupational accidents (0.67:0.59-0.76). Women white-collar-workers were more likely than their male counterparts to have a temporary contract (1.34:1.09-1.63), be exposed to psychosocial hazards and discrimination (2.47:1.49-4.09) and have occupational diseases (1.91:1.28-2.83). Gender inequalities were higher in the industry sector.

CONCLUSIONS

There are substantial gender inequalities in employment, working conditions, and work-related health problems in Spain. These gender inequalities are influenced by social class and the economic sector, and should be considered in the design of public policies in occupational health.

The impact of public employment on health and health inequalities: evidence from China

Because the public and private sectors often operate with different goals, individuals employed by the two sectors may receive different levels of welfare. This can potentially lead to different health status. As such, employment sector offers an important perspective for understanding labor market outcomes. Using micro-level data from a recent Chinese household survey, this study empirically evaluated the impact of employment sector on health and within-sector health inequalities. It found that public sector employment generated better health outcomes than private sector employment, controlling for individual characteristics. The provision of more job security explained an important part of the association between public sector employment and better health. The study also found less health inequality by social class within the public sector. These findings suggest that policymakers should think critically about the "conventional wisdom" that private ownership is almost always superior, and should adjust their labor market policies accordingly.

Gender and age disparities in the associations of occupational factors with alcohol abuse and smoking in the French working population

BACKGROUND

This study assessed the associations of short-term employment, physical and psychological occupational demands, and job dissatisfaction with alcohol abuse (using the Audit-C test) and daily smoking among working French men and women in different age groups.

METHODS

The sample included 13,241 working people, 18-29, 30-39, and 40-59-years-old, randomly selected in France and interviewed by phone. Occupation, type of employment, physical demands, psychological demands, job dissatisfaction, gender, age, educational level, and income were considered. Data were analyzed with logistic models.

RESULTS

Alcohol abuse affected 20.4% of men and 7.5% of women; smoking 32.1% and 24.2%, respectively. Their patterns of association with the occupational factors varied with gender and age. Job dissatisfaction was the leading factor among young men (adjusted odds ratio for alcohol abuse and smoking: 1.71 and 2.02), whereas short-term employment was the leading factor among young women (1.69 and 1.58), this pattern being reversed in older generations. The pattern of associations of physical and psychological demands with outcomes is more complex, but overall psychological demands were more important for women (especially the younger ones) than men, especially for smoking (OR>1.6). Smoking within 5 min after waking was much more common among male and female smokers with these occupational factors, suggesting a potential dependency.

CONCLUSIONS

Workers with short-term employment and occupational demands are subject to a higher risk for alcohol abuse and smoking with high gender and age disparities. Gender and age should be considered when designing measures to prevent substance abuse related to occupation.

Maternity care professionals' perceptions of supporting employed women in Norway

The World Health Organization calls on health professionals to support women in combining maternity and work. The aim of this study was to explore midwives' and public health nurses' perceptions of supporting employed women to balance work and family life during pregnancy and early motherhood. An exploratory design, including multistage focus group interviews, was used. The focus group consisted of five midwives and one public health nurse who was working in maternity care. The data were analyzed by using qualitative content analysis. The comprehensive theme, "empowering the women when they are in 'another' state of normality", was based on two themes, "being in dialogue with the women" and "supporting the women to manage daily activities". The first theme was based on the subthemes, "perceiving the women to be in 'another' state of normality" and "providing an open atmosphere for dialogue", while the second subtheme was based on "confirming self-esteem" and "suggesting adjustments at work". The midwives and public health nurse empowered the women by enhancing their ability to carry out the self-care that was necessary in order to manage both their work and family life. Collaboration between maternity healthcare providers and employers should be developed in order to support employed women.

Monitoring Social Determinants of Health Inequalities: The Impact of Unemployment among Vulnerable Groups

Surveillance of social determinants of health inequalities is an essential but still underdeveloped issue in public health. Existing research has identified unemployment as an important social determinant of health inequalities. This cross-sectional study investigates the impact of unemployment on mental health outcomes among vulnerable groups, using the 2006 Catalonian Health Survey (N = 8,591). The authors estimate the prevalence ratios and differences (excess of prevalence) for poor mental health in the unemployed and employed, with 95 percent confidence intervals. After taking into account the interactions among social mechanisms of inequality and related factors, the authors identified seven vulnerable groups to monitor. Primary findings indicate that unemployment has a greater adverse effect on the mental health of male manual workers, single mothers, main-earner women, and manual workers without unemployment benefits for both sexes. Findings support the need to devote more research to the surveillance of unemployment as a social determinant of health inequalities, to identify additional unemployment indicators, and to consider how various social mechanisms of inequality interact with each other to produce health inequalities among vulnerable groups.
