Role of SES on the association between childhood parental death and adulthood suicidal ideation: a mediation analysis using longitudinal dataset in South Korea

Table 2 Weighted distribution of mediators (adulthood education attainment and adulthood household income), and incidence of adulthood suicidal ideation in Korea

	Suicidal ideation in 2012–2019
	Early adulthood: 19–39 years old (N = 12,171,989)			Middle adulthood: 40–59 years old (N = 11,802,078)			Late adulthood: ≥60 years old (N = 5,500,948)

^a: P-value of the Rao-Scott design-adjusted chi-square test comparing the incidence of suicidal ideation across the different groups
^b: P-value of the t-test comparing the incidence of adulthood suicidal ideation, and mean of the household income
^c: Mean (standard deviation)
d: The early and middle adulthood groups: high school graduate or lower (low), and college graduate or more (high); the late adulthood group: middle school graduate or lower (low), and high school graduate or more (high)
^e: Equivalized household income with logarithmic transformation
