SELF-RATINGS OF HEALTH BY AGE AND BIRTH COHORT: FOR WHOM DO THEY PREDICT MORTALITY?

Abstract Global self-rated health as a predictor of mortality has become one of the most reliable outcomes in population-based follow-up studies. However, few studies focus on age or birth cohort differences in the mortality predictiveness of self-ratings of health. Personal knowledge of health accumulates throughout the life course, leading to the hypothesis that self-rated health would be most predictive in old age or in earlier birth cohorts. However, the pronounced effect of self-rated health on mortality means that those with the higher mortality risk of poor self-rated health in earlier adulthood would be less likely to survive to old age, potentially diminishing the effect through selective survival. In this paper we test for potential variations in the effects of age and birth cohort on the association between self-rated health and mortality in a large sample of adults aged 25-101 in the Panel Study of Income Dynamics (N=6437) followed from 1999-2019. We ask if self-rated health -- net of sociodemographic factors, physical and mental health conditions, and health risk behaviors – is equally predictive of mortality in three age groups spanning young, middle, and late adulthood, and in four birth cohorts. Fully adjusted models show that self-rated health was the most predictive for the group aged 41-64, and for those born 1946-1980, and that there were nearly null effects for those aged 25-40 or born 1981-1994. Thus, the effects of self-rated health on mortality vary by age and cohort, in ways that support both knowledge-based and selective survival interpretations of the association.

Differential Associations of Sports Participation With Self-Rated Health and Depressive Symptoms Among Japanese Adolescents.

We aimed to evaluate the associations of sports participation with self-rated health and depressive symptoms in a nationally representative sample of Japanese adolescents. A questionnaire survey was conducted with 1,658 adolescents aged between 12 and 21 years. Sports participation levels were divided into high-frequency, moderate-frequency, low-frequency, and no-participation groups. Self-rated health was evaluated using a four-grade scale. Depressive symptoms were assessed using the Japanese version of the Patient Health Questionnaire-8. Other lifestyle behaviors were also surveyed. The associations of sports participation with self-rated health and depressive symptoms were examined using multiple logistic regression analysis. The participants in the high- (odds ratio (OR), 0.45) and moderate-frequency (OR, 0.46) groups were less likely to self-report poor health than those in the non-participation group. By contrast, a U-shaped association was found between sports participation and depression, in which the participants in the moderate-frequency group (OR, 0.52) were less likely to have depressive symptoms. The OR for the high- (0.89) and low-frequency (0.91) groups were not significant. Furthermore, eating regular breakfasts, six or more days/week, and having shorter screen times of less than two hours/day were negatively associated with poor self-reported health and depressive symptoms. Moderate- to high-frequency sports activities are associated with a reduced risk of poor self-rated health among Japanese adolescents. However, only moderate-frequency activities were associated with a reduced risk of depression. Participation in optimal sports activities may effectively lower the risk of poor health in adolescents.

Insufficient Workplace Infection Control and Unhealthy Lifestyle Behaviors Are Related to Poor Self-Rated Health During the COVID-19 Pandemic.

This study investigated whether workers who practiced unhealthy lifestyles but worked under organizations with insufficient control against coronavirus disease 2019 (COVID-19) would pose a synergistic risk of poor self-rated health (SRH). A total of 22,637 workers (men, 48.5%) were extracted from an online survey during the COVID-19 pandemic in Japan (December 2020). Multiple logistic regression analyses were performed to estimate adjusted odds ratio (AOR) against poor (poor, fair) SRH. Accumulation of unhealthy lifestyle behaviors (AOR, 1.49 to 4.40; P < 0.05) and insufficient infection control (AOR, 1.80; P < 0.05) were independently related to poor SRH; however, when these factors were combined, SRH was additively worsened (AOR, 2.14 to 7.72; P < 0.05). This study highlights that not only unhealthy lifestyle practices but also poor organizational management against infection would worsen workers' SRH during the COVID-19 pandemic.

The spiral of disadvantage: Ethnolinguistic discrimination, acculturative stress and health in Nahua indigenous communities in Mexico.

The aim of this study was to test the hypothesis that ethnic and ethnolinguistic discrimination, and Post-Traumatic Stress Disorder (PTSD) related to being Indigenous as well as different aspects of acculturative stress, are associated with poorer health and higher levels of depression among the Nahua Indigenous communities. Our quantitative survey was carried out in four different regions inhabited by the Nahua people in Mexico. Self-rated health and depression, the symptoms of PTSD, two facets of acculturative stress and ethnolinguistic discrimination were assessed by questionnaires. The data were analyzed using binary logistic regression models. The symptoms of PTSD and acculturative stress experienced in the workplace were significantly associated with a higher risk of poor self-rated health, adjusted for various socio-demographic characteristics. Acculturative stress, discouragement of language use, language avoidance and ethnolinguistic discrimination were related to a higher risk of depression and PTSD. Our research implies that ethnic and linguistic discrimination, acculturative stress and the memory of harm linked to being Indigenous reflected in the symptoms of PTSD, are important predictors of poorer health and depression among Nahua groups in Mexico. These adverse effects could be significantly counteracted by effective dealing with stigmatization and discrimination against Indigenous people in Mexico and by replacing strong assimilation pressures with integrational approaches that respect ethnolinguistic diversity and reduce socioeconomic marginalization.

Over-indebtedness and health in Switzerland: A cross-sectional study comparing over-indebted individuals and the general population.

Previous international studies have shown that over-indebtedness is associated with poor health. However, in Switzerland research addressing over-indebtedness is widely lacking, strongly needed and particularly important because it is evidently a rising but still commonly tabooed, socially "undesired" and highly stigmatized phenomenon that is rarely discussed and largely ignored and unexplored. A cross-sectional survey was conducted among over-indebted adults seeking advice from one of the four official debt advisory centers in the Canton of Zurich. The survey finally included 219 respondents participating voluntarily and anonymously. This sample was then linked with a comparable subsample of the nationally representative Swiss Health Survey of 2017, namely 1,997 respondents of the same age from the Canton of Zurich. For reasons of comparability identical health questions and measures were taken from the Swiss Health Survey and used in the over-indebtedness survey. The pooled or combined dataset covered a total of 2,216 adult individuals. Remarkably high prevalence rates and relative risks of poor self-rated health, severe musculoskeletal and sleep disorders and moderate to severe depression were observed among over-indebted individuals compared to the general population. More than 50% of the over-indebted individuals had poor general health or moderate to severe depression compared to the general population with 14% and 7%, respectively. And far above one third of the over-indebted but 'only' between 6% and 8% of the general population showed severe musculoskeletal disorders and sleep disorders. Even after adjustment for various control variables and covariates, over-indebtedness increased the odds ratios for poor health outcomes consistently and dramatically, i.e. by a factor of 8 and more (aOR = 8.5-11.6). Over-indebtedness in Switzerland has particularly negative effects on various aspects of the health of the persons concerned, irrespective of their demographic characteristics and their social and employment status.

Perceived healthcare discrimination and well-being among older adults in the United States and Brazil

Despite well-documented evidence illustrating the relationship between discrimination and health, less is known about the influence of unfair treatment when receiving medical care. Moreover, our current knowledge of cross-national and racial variations in healthcare discrimination is limited in aging populations. This article addresses these gaps using two harmonized data sets of aging populations to clarify the relationship between healthcare discrimination and health in the United States and Brazil. We use nationally representative, harmonized data from the Health and Retirement Study in the United States and the Brazilian Longitudinal Study of Aging to examine and compare perceived discrimination in the healthcare setting and its relationship to self-rated health, depression diagnosis, and depressive symptoms across national contexts. Using Poisson regression models and population attributable risk percent estimates, we found that aging adults reporting healthcare discrimination were at higher risk of poor self-rated health, diagnosed depression, and depressive symptoms. Our results also suggest that reducing perceived healthcare discrimination may contribute to improved self-rated health and mental well-being in later life across racialized societies. In two comparative settings, we highlight the differential impact of healthcare discrimination on self-rated health and depression. We describe the implications of our study's findings for national public health strategies focused on eliminating discrimination in the healthcare setting, particularly among aging countries.

Poor worker's long working hours paradox: evidence from the Korea National Health and Nutrition Examination Survey, 2013-2018.

BackgroundBecause income and working hours are closely related, the health impact of working hours can vary according to economic status. This study aimed to investigate the relationship between working hours and the risk of poor self-rated health according to household income level.MethodsWe used the data from the Korea National Health and Nutrition Examination Survey VI and VII. The information on working hours and self-rated health was obtained from the questionnaire. After stratifying by household income level, the risk of poor self-rated health for long working hour group (≥ 52 hours a week), compared to the 35–51 working hour group as a reference, were calculated using multiple logistic regression.ResultsLong working hours increased the risk of poor self-rated health in the group with the highest income, but not in the group with the lowest income. On the other hand, the overall weighted prevalence of poor self-rated health was higher in the low-income group.ConclusionsThe relationship between long working hours and the risk of poor self-rated health varied by household income level. This phenomenon, in which the health effects of long working hours appear to diminish in low-income households can be referred to as the ‘poor worker’s long working hours paradox’. Our findings suggest that the recent working hour restriction policy implemented by the Korean government should be promoted, together with a basic wage preservation to improve workers’ general health and well-being.

Change in cardiorespiratory fitness on self-rated health: prospective cohort study in 98 718 Swedish adults.

Aim: To study how change in cardiorespiratory fitness over time is associated with the development of poor self-rated health in healthy Swedish adults, and whether this association varies with sex, age, body mass index and cardiorespiratory fitness at baseline. A secondary aim was to study the influence of other predictors of self-rated health. Methods: A total of 98,718 participants (45% women, mean age 42.2 years) with two assessments from occupational health service screenings between 1988 and 2019 (mean duration 4.3 years), with good self-rated health at baseline were included. Cardiorespiratory fitness was assessed as estimated maximal oxygen consumption using submaximal cycle testing. Change in cardiorespiratory fitness was expressed as percentage annual change. Poor self-rated health at follow-up was defined as percieving self-rated health as 'poor' or 'very poor'. Results: A large decrease in cardiorespiratory fitness (⩾-3%) was associated with a 34% higher risk of poor self-rated health compared to maintainers (-1 to +1%) after multi-adjustment including change in body mass index, back/neck pain, stress, exercise habits and sleep quality or sleep problems. The associations for decreasers were stronger with longer follow-up time (>10 years). Preserving, or changing to, risk level for body mass index, back/neck pain, stress, exercise and sleep quality/problems were associated with a higher risk of poor self-rated health. Conclusions: Preserving or increasing cardiorespiratory fitness is associated with a lower risk of poor self-rated health, independently of change in other health-related variables, which may act as a protection against future poor self-rated health. This is of high clinical value, and strategies for maintaining or improving cardiorespiratory fitness have the potential to influence both disease and mortality.

Working-age adults using food banks in England have significantly poorer health and higher rates of mental health conditions than adults in the general population: A cross-sectional quantitative study.

Food bank use has risen rapidly in the UK since 2010. The negative health impacts of food insecurity are well-documented, but there is a lack of quantitative research exploring the health of people using food banks, who are most often severely food insecure. To address this gap, this study compares health outcomes between working-age adults using food banks and those in the general population in England, investigating whether adults using food banks are disproportionately affected by poor health, even after accounting for socioeconomic differences. Data from a survey of 598 adults using Trussell Trust food banks in 2016-2017 were merged with data from the Health Survey for England (HSE) from 2016. Outcome variables of interest were: self-rated health, life-limiting health conditions (disability) and self-reported metabolic, cardiovascular, musculoskeletal and mental health conditions. Logistic regression models were used to examine the odds of adults using food banks having health conditions, disability and poor self-rated health compared to the general population. The prevalence rates of poor self-rated health, disability, mental health disorders and musculoskeletal conditions were significantly higher among adults using food banks than the general population (p<.05 for all outcomes). These associations remained after accounting for gender, age, marital status, employment and education. This comparative study highlights the many health disadvantages among adults using food bank compared to the general population. The higher risk of poor self-rated health, disability and mental health conditions was not fully explained by measures of low socioeconomic status. Possible explanations for these findings include: first, that poor health may increase vulnerability to food insecurity, and, in turn, use of food banks; second, that experiences of food insecurity and food bank use may cause declines in health; and third, that food bank use and poor health may be joint outcomes arising from the last decade of austerity in the UK.

The role of welfare regimes in the relationship between childhood economic stress and adult health: a multilevel study of 20 European countries.

Childhood economic conditions are important for adult health, and welfare regimes may modify this relationship by altering exposure to social determinants of health. We examine the association between childhood economic stress (CES) and self-rated health (SRH) and cancer (any type), and how welfare regimes may influence these associations. We used data from European Social Survey round 7. Our study is based on 30 024 individuals between 25 to 75 years from 20 European countries grouped into five welfare regimes (Scandinavian, Anglo-Saxon, Bismarckian, Southern and Eastern). Multilevel models were used to assess the association between CES and SRH/cancer, and interactions between CES and welfare regimes. CES increased the risk of poor SRH (RR 1.41, 95% CI 1.29–1.54) and cancer (RR 1.19, 95% CI 1.02–1.37). Controlling for adult socioeconomic status slightly reduced risk for poor SRH, but not cancer. CES increased the probability of poor SRH in the Southern and Eastern regime, and the probability of cancer in the Anglo-Saxon regime, relative to the Scandinavian regime. Childhood economic stress increases the risk of poor self-rated health and cancer. More comprehensive welfare states mitigate these associations, which emphasizes the impact of welfare policies on long-term health outcomes of childhood economic conditions.

Exposure to discrimination and subsequent changes in self-rated health: prospective evidence from the UK's Life Opportunities Survey

ObjectivesWe sought to estimate risk of poor self-rated health (SRH) following exposure to disability-related and other forms of overt discrimination in a cohort of working age adults. Study designThe study design is a population-based cohort survey. MethodsSecondary analysis of data collected in Waves 1 and 2 of the UK's Life Opportunities Survey which at Wave 2 involved the participation of 12,789 working age adults. Adjusted prevalence rate ratios were used to estimate the impact of exposure to disability and non-disability discrimination on two measures of SRH at Wave 2, controlling for SRH status at Wave 1. ResultsExposure to disability discrimination in the previous year was reported by 3.9% of working age British adults. Other forms of discrimination were reported less frequently (age: 3.7%, ethnicity: 2.5%, gender: 1.6%, religion: 0.8%, sexual orientation: 0.4%). In all analyses, there were stronger associations between exposure to disability discrimination and poor SRH at Wave 2 when compared with exposure to other forms of discrimination. ConclusionsDisability discrimination represents a violation of human rights. It is also likely to be a major contributor to the health inequities experienced by working age adults with disability.

Association between Working Hours and Self-Rated Health.

This study compared the association between working hours and self-rated health (SRH) according to sex, socioeconomic status, and working conditions. In all, 25,144 participants were selected from the Korea National Health and Nutrition Examination Survey (KNHANES), conducted from 2010 to 2018. The risks of poor SRH, according to working hours, were investigated using multiple logistic regression. Both short and long working hours were associated with poor SRH. Men working short hours and women working long hours were at risk of poor SRH. Workers with fewer than nine years of education were at risk of poor SRH when working short hours, whereas workers with more than nine years of education were at risk when working long hours. Similarly, simple laborers were at risk of poor SRH when working short hours, while managers and professional workers were at risk when working long hours. When working for short hours, paid employees were at risk of poor SRH. Workers with a non-fixed work schedule showed no risk of poor SRH when working long or short hours. In conclusion, workers working short hours with low education and workers working long hours with high education were at risk of poor SRH. Working conditions were significantly related to the association between SRH and working hours.

Do Welfare Regimes Moderate Cumulative Dis/advantages Over the Life Course? Cross-National Evidence from Longitudinal SHARE Data.

This study aimed to examine the cumulative disadvantage of different forms of childhood misfortune and adult-life socioeconomic conditions (SEC) with regard to trajectories and levels of self-rated health in old age and whether these associations differed between welfare regimes (Scandinavian, Bismarckian, Southern European, and Eastern European). The study included 24,004 respondents aged 50-96 from the longitudinal SHARE survey. Childhood misfortune included childhood SEC, adverse childhood experiences, and adverse childhood health experiences. Adult-life SEC consisted of education, main occupational position, and financial strain. We analyzed associations with poor self-rated health using confounder-adjusted mixed-effects logistic regression models for the complete sample and stratified by welfare regime. Disadvantaged respondents in terms of childhood misfortune and adult-life SEC had a higher risk of poor self-rated health at age 50. However, differences narrowed with aging between adverse-childhood-health-experiences categories (driven by Southern and Eastern European welfare regimes), categories of education (driven by Bismarckian welfare regime), and main occupational position (driven by Scandinavian welfare regime). Our research did not find evidence of cumulative disadvantage with aging in the studied life-course characteristics and age range. Instead, trajectories showed narrowing differences with differing patterns across welfare regimes.

Health risks associated with social isolation in general and in young, middle and old age.

IntroductionHealth effects of social isolation are well-studied at older age, in English-speaking countries, for individual health conditions, and based on unidimensional measures of isolation. Hardly any evidence exists for younger ages, for continental European and particularly German-speaking countries and based on multidimensional measures of isolation. This study therefore aimed to examine prevalence rates and associations of social isolation with various health conditions and behaviors in the entire Swiss population and across different age groups.MethodsNationally representative cross-sectional data from the Swiss Health Survey collected in 2012 were used and analyzed. The study sample covered 21,597 randomly selected adolescents and adults living in Switzerland and aged 15 and older. A multifactorial five-item social integration index was used to assess social disconnectedness and perceived isolation.ResultsSocial isolation has been found to steadily increase with age and almost consistently to be strongly associated with poor health conditions and unfavorable behaviors across all ages. Nearly a quarter of the general population could be categorized as either only partly integrated or even poorly integrated and largely isolated. The socially isolated people independent of their age showed strongly elevated relative risks of poor self-rated health (aOR = 4.0), musculoskeletal disorders (aOR = 2.8), moderate to severe depression (aOR = 11.5), and multiple health problems (aOR = 5.0). They were also found to be at comparably high risk of behaving unhealthy with regard to physical inactivity (aOR = 2.2), poor diet (aOR = 1.9) and use of psychotropic medications (aOR = 3.6). Although prevalence rates of poor health conditions and behaviors differed greatly between the studied age groups, strong associations and clear dose-response relationships have been found separately for all age groups and particularly for the youngest. A fairly weak or no association at all (depending on the age group) with the degree of social integration was observed only for daily smoking.ConclusionsSocial isolation may be less prevalent at younger ages, but is then even more strongly associated with poor health conditions and behaviors than at older ages.

How Did Employment and Financial Strain Affect the Self-rated Health of Lone Mothers Around the Time of the Economic Crisis? A Cross-sectional Comparison of the United Kingdom and Sweden

Lone mothers face higher risk of poor self-rated health (SRH) than coupled mothers, partly explained by financial strain, non-employment, and welfare context. Comparing the United Kingdom and Sweden, we sought to determine how the economic crisis of 2008 affected the inequality in lone and coupled mothers SRH and what socioeconomic factors impacted this. Survey data was divided into periods corresponding to before, during, and after the economic crisis. Logistic regression was used to evaluate the impact of socioeconomic factors. Financial strain explained 70%–80% of the excess risk for poor health among Swedish lone mothers and 40% of those in the United Kingdom. Controlling for background and socioeconomic factors eliminated the health inequality among Swedish mothers. In the United Kingdom this inequality remained and may reflect the impact of social mechanisms such as stigma. Converse to what was expected, we did not observe significant variation over time in factors affecting SRH, nor did we find conclusive evidence of the impact of the economic crisis on the SRH of lone mothers. Factors that may account for these counterintuitive results, including retrenchment of the Swedish welfare state, economic lag, and reduction in overall inequality in health, are discussed.

Perinatal health of refugee and asylum-seeking women in Sweden 2014-17: a register-based cohort study.

BackgroundAn increasing number of migrants have fled armed conflict, persecution and deteriorating living conditions, many of whom have also endured risky migration journeys to reach Europe. Despite this, little is known about the perinatal health of migrant women who are particularly vulnerable, such as refugees, asylum-seekers, and undocumented migrants, and their access to perinatal care in the host country.MethodsUsing the Swedish Pregnancy Register, we analyzed indicators of perinatal health and health care usage in 31 897 migrant women from the top five refugee countries of origin between 2014 and 2017. We also compared them to native-born Swedish women.ResultsCompared to Swedish-born women, migrant women from Syria, Iraq, Somali, Eritrea and Afghanistan had higher risks of poor self-rated health, gestational diabetes, stillbirth and infants with low birthweight. Within the migrant population, asylum-seekers and undocumented migrants had a higher risk of poor maternal self-rated health than refugee women with residency, with an adjusted risk ratio (RR) of 1.84 and 95% confidence interval (95% CI) of 1.72–1.97. They also had a higher risk of preterm birth (RR 1.47, 95% CI 1.21–1.79), inadequate antenatal care (RR 2.56, 95% CI 2.27–2.89) and missed postpartum care visits (RR 1.15, 95% CI 1.10–1.22).ConclusionRefugee, asylum-seeking and undocumented migrant women were vulnerable during pregnancy and childbirth. Living without residence permits negatively affected self-rated health, pregnancy and birth outcomes in asylum-seekers and undocumented migrants. Pregnant migrant women’s special needs should be addressed by those involved in the asylum reception process and by health care providers.

The relationship between self-reported sensory impairments and psychosocial health in older adults: a 4-year follow-up study using the English Longitudinal Study of Ageing

ObjectivesTo explore cross-sectional and longitudinal relationships between self-reported hearing and vision impairments and self-rated health, quality of life (QoL) and depressive symptoms at 4-year follow-up. Study designThe study involved cross-sectional and longitudinal analyses with 4-year follow-up using data from the English Longitudinal Study of Ageing. MethodsCommunity-dwelling adults (n = 3931) aged ≥50 years from the English Longitudinal Study of Ageing participated in this study. Self-reported hearing and vision were defined as good or poor. Self-rated health was treated as a dichotomous variable (good and poor health). QoL was based on the 19-item Critical Appraisal Skills Programme and treated as a continuous variable (score 0–57). Depressive symptoms were assessed using the eight-item Center for Epidemiologic Studies Depression Scale (CES-D8) and defined as CES-D≥3. Relationships between sensory impairments and self-rated health and depressive symptoms were analysed using logistic regression. Linear regression was used to assess the relationships between sensory impairments and QoL. ResultsIn cross-sectional analyses, both self-reported hearing and vision impairment were positively associated with all outcomes assessed. In longitudinal analyses, self-reported poor hearing and vision were associated with increased risks of poor self-rated health (hearing: odds ratio [OR] 1.65, 95% confidence interval [CI] 1.32, 2.05; vision: OR 1.57, 95% CI 1.16, 2.12) and depressive symptoms (hearing: OR 1.35, 95% CI 1.07, 1.71; vision: OR 1.44, 95% CI 1.09, 1.90) after adjustment for sociodemographic and lifestyle factors, chronic illness, mobility limitations and cognition. Poor hearing and poor vision were not associated with reduced QoL after adjustment for covariates. ConclusionsThe findings stress the importance of identifying and addressing sensory impairments in older adults to improve their health and well-being.

Welfare regimes modify the association of disadvantaged adult-life socioeconomic circumstances with self-rated health in old age.

Welfare regimes in Europe modify individuals' socioeconomic trajectories over their life-course, and, ultimately, the link between socioeconomic circumstances (SECs) and health. This paper aimed to assess whether the associations between life-course SECs (early-life, young adult-life, middle-age and old-age) and risk of poor self-rated health (SRH) trajectories in old age are modified by welfare regimes (Scandinavian [SC], Bismarckian [BM], Southern European [SE], Eastern European [EE]). We used data from the longitudinal SHARE survey. Early-life SECs consisted of four indicators of living conditions at age 10. Young adult-life, middle-age, and old-age SECs indicators were education, main occupation and satisfaction with household income, respectively. The association of life-course SECs with poor SRH trajectories was analysed by confounder-adjusted multilevel logistic regression models stratified by welfare regime. We included 24 011 participants (3626 in SC, 10 256 in BM, 6891 in SE, 3238 in EE) aged 50 to 96 years from 13 European countries. The risk of poor SRH increased gradually with early-life SECs from most advantaged to most disadvantaged. The addition of adult-life SECs differentially attenuated the association of early-life SECs and SRH at older age across regimes: education attenuated the association only in SC and SE regimes and occupation only in SC and BM regimes; satisfaction with household income attenuated the association across regimes. Early-life SECs have a long-lasting effect on SRH in all welfare regimes. Adult-life SECs attenuated this influence differently across welfare regimes.

Internal workplace violence from colleagues is more strongly associated with poor health outcomes in nurses than violence from patients and families.

To examine the associations between different workplace violence sources and health outcome in nurses. Workplace violence is a major threat to nurses' physical and mental health. Other workers in the health sector, patients and visitors can cause workplace violence. To effectively prevent workplace violence-related health problems, the differential impact of internal and external violence needs to be explored. A cross-sectional survey of 1,690 fully employed female nurses. A self-administered questionnaire was used to record the nurses' experiences of workplace violence, including types (physical, psychological, verbal and sexual) and sources (internal and external) of violence. Data on psychosocial work conditions including work shift, psychological job demands, job control and workplace justice, were also collected. The nurses' health condition was measured using the 5-item Brief Symptom Rating Scale and Self-Rated Health Scale and multivariable logistic regression was used to examine the associations between workplace violence and health. The study was carried out in 2015-2016. Sixty percent of the internal workplace violence was psychological and verbal and adverse psychosocial work conditions were associated with workplace violence. After adjustment for demographic characteristics and psychosocial work conditions, internal workplace violence resulted in higher risks of poor self-rated health and mental health than did external workplace violence, particularly in nurses who had experienced psychological and verbal violence. Internal workplace violence in the form of psychological and verbal violence had a stronger effect on nurses' health than did external workplace violence. Organization-level measures should be implemented to prevent internal violence.
