Prospective Cohort Study of Sociodemographic Factors, Including Occupation and Subsequent Unemployment, Under COVID-19 in Japan

Abstract

Abstract Background: We examined the relationship between sociodemographic factors, including occupation and unemployment, among workers during COVID-19 in Japan.Methods: We conducted a prospective cohort study using a self-administrated questionnaire. We surveyed the socioeconomic status, personal characteristics, and occupation of recruited workers at baseline (December 22–25, 2020); subsequent unemployment was examined at follow-up (February 18-19, 2021). We determined the odds ratio (OR) of unemployment for sociodemographic status and occupation. The multivariate model was adjusted for sex and age.Results: Among the 19,941 participants, 725 (3.6%) had experienced unemployment. Multivariate analysis showed that the OR and 95% confidence interval (CI) of unemployment associated with sex were 1.35 (1.14–1.60) for women compared with men. With increasing age, the OR for unemployment was lower (OR, 0.98; 95% CI, 0.97–0.99; P <0.001), adjusted for sex. The OR and 95% CI for the association with marital status were as follows: 1.33 (1.03–1.71) for being married (spouse not working); 2.09 (1.65–2.64) for bereaved or divorced; and 1.29 (1.07–1.56) for unmarried compared with married (spouse working). The respective figures for the association with annual household income were as follows: 4.05 (3.00–5.46) for <2 million yen; 2.12 (1.62–2.78) for 2–4 million yen; and 1.46 (1.11–1.93) for 4–6 million yen, compared with >10 million yen. The figures for the association with education were 1.73 (1.12–2.66) for junior high or high school and 1.83 (1.19–2.83) for vocational school, junior college, or technical school. The association with occupation was 2.01 (1.63–2.48) for temporary or contract employees, 1.35 (1.02–1.78) for self-employed, and 3.02 (1.68–5.42) for agriculture, forestry, or fishing, compared with general employees; it was 0.56 (0.40–0.79) for public employees, faculty members, or non-profit organization employees. The association with job type was 1.25 (1.04–1.51) for jobs mainly involving interpersonal communication and 1.85 (1.55–2.21) for mainly manual or physical labor, compared with mainly desk work.Conclusions: COVID-19 appears to have created difficulties for previously vulnerable groups. This suggests the need for employment and economic support for such individuals.
