Differences in self-rated health and work ability between self-employed workers and employees: Results from a prospective cohort study in the Netherlands

Work participation, social roles, and empowerment of Q-fever fatigue syndrome patients ≥10 years after infection

OBJECTIVE

To determine work participation, social roles, and empowerment of QFS patients ≥10-year after infection.

METHODS

QFS patients ≥10-year after acute infection, who were of working age, participated in a cross-sectional survey study. Work participation, fulfilment of social roles, and empowerment outcomes were studied for the total population, as well as for subgroups based on employment type and current work status. Associations between empowerment, work and social roles were examined.

RESULTS

291 participants were included. Of the 250 participants who had paid work before Q-fever, 80.4% stopped working or worked less hours due to QFS. For each social role, more than half of the participants (56.6-87.8%) spent less time on the role compared to before Q-fever. The median empowerment score was 41.0 (IQR: 37.0-44.0) out of 60. A higher empowerment score was significantly associated with lower odds of performing all social roles less due to QFS (OR = 0.871-0.933; p<0.001-0.026), except for parenting and informal care provision (p = 0.070-0.460). No associations were found between empowerment and current work status.

CONCLUSION

Work participation and fulfilment of social roles is generally low in QFS patients. Many of the participants stopped working or are working less hours due to QFS, and most spent less time on social roles compared to before Q-fever. Minor variation was seen in total empowerment scores of participants; however, these slight differences were associated with the fulfilment of social roles, but not work participation. This new insight should be further explored in future studies.

Difference in employment status and onset of disability among Japanese community-dwelling older adults: a prospective cohort study

OBJECTIVE

This prospective cohort study investigates the relationship between the onset of disability and employment status.

METHODS

We investigated 3,741 community-dwelling adults aged 70 or older, who participated in a population-based cohort study in Japan. Their onset of disability was monitored monthly using the long-term care insurance certification registration system, for five years from baseline. Based on an employment status questionnaire, we categorized participants into three groups: (1) employee, (2) self-employed, and (3) not working. Covariates included demographic information, medical history, number of medications, educational level, living alone, social group engagement, smoking status, walking speed, instrumental activities of daily living, global cognitive function, and depressive symptoms. Missing values were managed using multiple imputation. Cox proportional hazard models were used to calculate hazard ratios (HRs) with 95% confidence intervals (CIs) for incident disability risk by employment status.

RESULTS

The disability incidence rates were 15.3/1,000 (95% CIs: 10.7-22.0) person-years among employees, and 33.0/1000 (95% CIs: 24.4-44.6) and 39.6/1000 (95% CIs: 36.5-43.0) person-years among self-employed and non-working participants, respectively. The adjusted HRs for the onset of disability among non-working and self-employed participants were 1.69 (95% CIs: 1.16-2.46, p = 0.007) and 1.63 (95% CIs: 1.01-2.62, p = 0.044) compared with employees, respectively. Similar results were found among men. Among women, disability onset was not associated with employment status.

CONCLUSIONS

Older adults' risk of disability onset differed according to their employment status. Older employees had a lower risk of disability onset than those not working or self-employed.

Glucose Metabolism in Midlife Is Associated With Preceding 30-Year Employment Trajectories: A Northern Finland Birth Cohort 1966 Study

OBJECTIVE

The aim of the study is to evaluate how glucose metabolism in midlife is related to preceding 30-year-long employment trajectories.

METHODS

In the Northern Finland Birth Cohort 1966, we compared glucose metabolism at 46 to employment trajectories (previously defined for men and women and named as high-educated, traditional, self-employed, delayed, and floundering; n = 6399).

RESULTS

Compared with individuals in high-educated trajectories, odds ratios for type 2 diabetes (T2D, 95% confidence interval) in traditional and floundering trajectories in men were 1.65 (1.02-2.68) and 2.42 (1.38-4.23) and in women 1.89 (1.04-3.43) and 2.60 (1.46-4.62), respectively. In self-employed trajectory in women, odds ratios for prediabetes and T2D were 1.66 (1.09-2.51) and 2.47 (1.21-5.04).

CONCLUSIONS

The highest risks for T2D in midlife were associated after traditional and floundering trajectories in men and women and after self-employment trajectory in women.

Self-employment and health inequality of migrant workers

Background

Self-employment is one of the most common forms of employment for migrant workers in China. However, migrant workers’ lifestyle and behavior, as well as health disparities among them, would be impacted by self-employment. This research aims to explore the mechanism and group differences of the effect of self-employment on health inequality among Chinese migrant workers.

Materials and methods

To explore the effect of self-employment on health inequalities among migrant workers, this research uses the data from the 2018 China Migrant Workers Dynamic Monitoring Survey, and the RIF-I-OLS decomposition method.

Results

We find that self-employment will reduce the health inequality of Chinese migrant workers significantly, especially among migrant workers with low education, low income, and low social integration. A further examination reveals that self-employment can directly promote the self-rated health of migrant workers. Additionally, it indirectly alleviates the health inequality among migrant workers by mediating effect of expanding access to public welfare, such as by establishing health records and strengthening health education.

Conclusion

The government should permit and encourage migrant workers to engage in self-employment. It is necessary to provide public services such as health education, health records, and health rights for migrant workers, and focus on the employment of migrant workers in city, especially those with low income and low education. we believe that measures should be taken to enhance migrant workers’ sense of belonging in urban China Only on this basis can health inequality among migrant workers be truly reduced.

Occurrence of Mental Illness and Mental Health Risks among the Self-Employed: A Systematic Review

We aimed to systematically identify and evaluate all studies of good quality that compared the occurrence of mental disorders in the self-employed versus employees. Adhering to the Cochrane guidelines, we conducted a systematic review and searched three major medical databases (MEDLINE, Web of Science, Embase), complemented by hand search. We included 26 (three longitudinal and 23 cross-sectional) population-based studies of good quality (using a validated quality assessment tool), with data from 3,128,877 participants in total. The longest of these studies, a Swedish national register evaluation with 25 years follow-up, showed a higher incidence of mental illness among the self-employed compared to white-collar workers, but a lower incidence compared to blue-collar workers. In the second longitudinal study from Sweden the self-employed had a lower incidence of mental illness compared to both blue- and white-collar workers over 15 years, whereas the third longitudinal study (South Korea) did not find a difference regarding the incidence of depressive symptoms over 6 years. Results from the cross-sectional studies showed associations between self-employment and poor general mental health and stress, but were inconsistent regarding other mental outcomes. Most studies from South Korea found a higher prevalence of mental disorders among the self-employed compared to employees, whereas the results of cross-sectional studies from outside Asia were less consistent. In conclusion, we found evidence from population-based studies for a link between self-employment and increased risk of mental illness. Further longitudinal studies are needed examining the potential risk for the development of mental disorders in specific subtypes of the self-employed.

Relationship between Employment Type and Self-Rated Health among Korean Immigrants in the US: Focusing on Gender and Number of Years in the US

Although Korean immigrants report worse self-rated health and a higher self-employment rate than other Asian immigrant groups, the relationship between their employment type and self-rated health is understudied. This study examines the relationship between employment type and self-rated health among Korean immigrants in the US. Survey data of 421 first-generation working-age (18-64 years old) Korean immigrants in the New York-New Jersey area were analyzed. The self-administrated survey questionnaire included 39 items (e.g., sociodemographic characteristics, self-rated health, and health insurance status). A logistic regression analysis was conducted to examine the relationship between the dependent variable-self-rated health (e.g., bad/not bad vs. good/very good)-and independent variable-employment type (e.g., work at non-ethnic firms, work at co-ethnic firms, self-employed, and unemployed)-by focusing on differences regarding gender and number of years living in the US. Self-employed and unemployed Korean immigrants were less likely to report good health compared to those working in non-ethnic firms. After controlling for sociodemographic characteristics (age, gender, marital status, education, health insurance status, membership in any Koran association, religion, and English proficiency), the relationship between employment type and self-rated health remained significant among female and recent Korean immigrants. More worksite interventions by occupational health nurses that target self-employed Korean immigrants, especially women and recent immigrants, are necessary.

Self-employment and cardiovascular risk in the US general population

Background

Studies on self-employment and cardiovascular risk are very limited. We examined the relationship between self-employment and cardiovascular risk among the general population in the United States from 1999 to 2016.

Methods

Using the National Health and Nutrition Examination Survey (NHANES), we identified all patients with hypertension (HTN), hyperlipidemia (HLD), diabetes mellitus (DM), stroke, heart failure (HF), and coronary artery disease (CAD) between 1999 and 2016. Type of job was defined based on the participant's response to the survey question as “an employee of a private company, business, or individual for wages, salary, or commission” or “self-employed in own business, professional practice or farm”. Multivariable logistic regression analyses were performed to adjust for confounders.

Results

Of 30,103 patients, 2835 (9.4%) were self-employed in their own business, professional practice, or farm and 27,268 (90.6%) were employed by a private company, business, or government. After adjusting for age, race, sex, BMI, marital status, educational level, health insurance status, smoking status, sleep duration and lipid profiles, self-employed individuals had a higher prevalence of HTN (OR: 1.12; 95% confidence interval [CI] 1.05–1.20), HLD (OR: 1.10; 95% CI 1.07–1.31), stroke (OR: 1.45; 95% CI 1.27–1.67), HF (OR: 1.17; 95% CI 1.03–1.32), and CAD (OR: 1.26; 95% CI 1.13–1.35) (all P v< 0.05).

Conclusions

Self-employment may be associated with greater cardiovascular risk in the US general population. Further prospective studies are urgently needed to establish the optimal preventive strategy to reduce cardiovascular risk in self-employed individuals.
