Description of each of the input variables

Variable	Description
Input variables measured during both adolescence (EAT 2010) and emerging adulthood (EAT 2018)
Teasing and/or harassment	“How often do any of the following things happen?” Response options included: never, less than once a year, a few times a year, a few times a month, at least once a week.
Race	“You are teased or harassed about your race” (test–retest r = 0.64)
Financial situation	“You are teased or harassed about your family's financial situation” (test–retest r = 0.61)
Sexual harassment	“You are teased or harassed in a sexual way (e.g., grabbing/pinching, sexual comments, unwanted touching, etc…”) (test–retest r = 0.64)
Weight	“You are teased about your weight” (test–retest r = 0.73)
Appearance	“You are teased about your appearance” (test–retest r = .73)
Neighborhood safety	Neighborhood safety was measured with two questions at both measurement occasions: “The crime rate in my neighborhood makes it unsafe to go on walks during the [day/night].” Response options ranged from strongly disagree (1) to strongly agree (4). Responses were reverse coded and summed, with higher scores indicating greater neighborhood safety, and achieved adequate internal consistency at both EAT 2010 (α = .80) and EAT 2018 (α = .82).
Food insecurity	EAT 2010: If participants indicated they had ever been hungry (e.g., Some months but not every month) and experienced any compromise to food adequacy (e.g., Sometimes we do not have enough to eat) in the past 12 months, they were categorized as food insecure (test–retest r = .77, test–retest agreement = 96%) EAT 2018: Participants who indicated that they (1) had eaten less than they felt they should because there wasn't enough money and (2) that they were hungry but did not eat because there was not enough money for food in the past 12 months, they were categorized as experiencing food insecurity (test–retest agreement = 81.2%).
Public assistance	“In the past year, did you or any member of your household receive WIC (Women, Infants, and Children Program) benefits or SNAP (Supplemental Nutrition Assistance Program or Food Stamp Program) benefits?” Response options: no, yes, I do not know. (test–retest agreement = 92.7%)
Input variables measured only during adolescence (EAT 2010)
Race/ethnicity	Response options: (1) White; (2) Black or African American; (3) Hispanic or Latino; (4) Asian American; (5) Native Hawaiian or other Pacific Islander; (6) American Indian or Native American; and (7) Other. Due to small cell sizes, race/ethnicity was modeled with 5 categories: Asian, Black/African American, Hispanic/Latino, white, and Mixed/Other (test–retest agreement = 98–100%).
U.S. nativity	“Were you born in the United States?” Response options: yes, no
Household language	“What language is usually spoken in your home?” Response options: (1) English; (2) A language other than English; and (3) English and another language about equally

Responses to both questions were combined into a single variable, reflecting the highest known level of education that participants’ parents attained.
Parental employment	“Does your [mother/father]” (1) work full time; (2) work part time; (3) not work for pay; (4) I do not know
Input variables measured only during emerging adulthood (EAT 2018)
Gender	“Are you…?” Response options: (1) Male, (2) Female, (3) Different identity (test–retest agreement = 100%)
Personal income	“What is your current yearly income before taxes and deductions? Please do not include the income of others in your household.” (1) None; (2) under $5000 a year; (3) $5000–14,999 a year; (4) 15,000‐24,999; (5) $25,000‐29,999; (6) $30,000‐39,999; (7) ≥ $40,000 (r = 0.74)
Student status	(1) Not a student (2) Full time (3) part time (4) graduate. Test–retest agreement = 92.0%
Personal education	“What is the highest level of education that you have completed?” Responses ranged from (1) middle school or junior high to (8) graduate or professional degree (MS, MBA, MD, PhD, etc). Due to small cell size, responses were categorized into five groups: less than high school, high school or GED equivalent, college degree, advanced degree, and vocational or other. Test–retest agreement = 92.0%
Living situation	Participants were asked who they lived with the majority of the time during the past year. Categories: alone, with roommates, with parents, other. Test–retest agreement = 100%
Work status	Participants were asked about their current work status. Categories: full time, part time, unemployed, other. Test–retest agreement = 83.0%
Hours of work (weekly)	“How many hours a week do you currently work for pay?” Categories: 1–19 h, 20–39 h, 40 h, more than 40 h (test–retest r = 0.89).
Financial difficulty	How difficult is it for you to get by financially right now? (Price, Choi, & Vinokur, 2002). Response options: Not at all difficult, Somewhat difficult, Very difficult or can barely get by, Extremely difficult or impossible. Due to small cell sizes, response options very difficult or can barely get by and extremely difficult or impossible were merged (test–retest agreement = 92%).
Everyday discrimination	Participants responded to three questions pertaining to everyday experiences of discrimination, such as being treated with less respect or courtesy or receiving poorer service than other people. Response options included: never, less than once a year, a few times a year, a few times a month, at least once a year. Everyday discrimination frequency ranges between 3–15 (α = 0.83, test–retest r = 0.69).
Stressful life events	Participants indicated whether or not they had experienced six stressful life events related to: police activity, physical abuse, sexual abuse, violent death of a close friend or family member, or exposure to serious physical violence in their environment. Survey items were based on the Life Events Questionnaire and Brief Trauma Questionnaire. Responses were summed to represent the number of events experienced (test–retest agreement = 85%).
Adverse childhood experiences	Adverse experiences in childhood (<18 years) were assessed by asking participants about their own experiences of physical, emotional, and sexual abuse as well as three questions regarding other dimensions of dysfunction in their childhood household. The authors defined participants as exposed to each type of maltreatment using the following definitions, informed by the ACEs Scale. Responses were summed to represent the number of events experienced (test–retest agreement = 85%).
