Late payments were measured from 2012 to 2014 (from 2013 to 2015 for the newly recruited members).; p-values of the Chi-square test compare the prevalence of suicidal behavior across the different groups; age and income were used as continuous covariates in multivariable analyses; depressed condition, past ideation, and past attempts were measured based on the 2011 survey (the 2012 survey for the newly recruited members), and dependent and other independent variables were measured based on the 2013 survey (the 2014 survey).
