Title: A Confederate Study of Indoor Tanning Facility Compliance with Laws

- This submission was designated as a Best of ASPO Abstract.
Trained and supervised pseudo-patrons called randomly selected indoor tanning facilities (indoor tanning salons, beauty salons/spas, gyms, apartment buildings) in 50 states and DC, posing as minors one year younger than the state’s permitted age to indoor tan (age 17 in states banning indoor tanning under 18) or age 16 in states with no age restriction. Using a semi-structured script, pseudo-patrons asked about scheduling an indoor tanning session, unlimited indoor tanning (contrary to FDA guidelines), risk of skin burns, and parental involvement requirements. Responses were coded, with discrepancies resolved by consensus, and summarized descriptively.
A total of 504 calls were completed to 206 indoor tanning salons, 111 gyms, 101 spas/beauty salons, and 86 apartment buildings. Overall, 55% of facilities would allow pseudo-patrons to book an appointment or “walk in” for indoor tanning, despite being underage, compared to 32% in states with under-18 bans. In states with minor restrictions, indoor tanning salons were least likely (48%) to permit minor indoor tanning and gyms, most likely to do so (56%). Twenty-six percent (26%) of staff did not ask pseudo-patrons their age, irrespective of law type. Forty-four percent (44%) of gyms/apartments did not require membership/tenancy to indoor tan. Most facilities (92%) offered unlimited indoor tanning packages or unlimited access to tanning beds when open. Only 52% of facility staff acknowledged that pseudo-patrons’ skin could be burned, when asked.
Although many states have laws restricting indoor tanning by minors, indoor tanning facilities were commonly non-compliant with age restrictions, suggesting inadequate law awareness and/or enforcement. Strategies must be identified to implement indoor tanning laws effectively and realize their benefits, including preventing skin burns, skin cancer, and other health consequences. Ongoing analyses are evaluating compliance when scheduling appointments online and by additional law provisions, state demographics, and U.S. region.

Title: Correlates of Human Papillomavirus Vaccination Among a Sample of Emerging Adults Aged 18-26 Living in Rural Locations in the Western United States

Human Papillomavirus (HPV) vaccination status and correlates were examined in a sample of emerging adults living in rural locations in the western United States. Eight hundred and ten (n=810) emerging adults residing in rural areas in 17 western U.S. states were recruited from online survey panels or by social media advertising from August 2024-2025 for a randomized trial. Emerging adults reported at baseline their HPV vaccine uptake status, including number of doses received. Using logistic regression analysis, we tested the association of demographics, attitudes, health care, and social media use with HPV vaccine uptake status (0=no/don’t know; 1=vaccinated) and vaccine doses received (0=0 or 1 dose/don’t know; 1=2 or 3 doses).
Overall, 424 (52.3%) rural emerging adults reported being vaccinated for HPV and 184 (22.7%) not being vaccinated, and 202 (24.9%) did not know. Of the 424 emerging adults vaccinated, 41 emerging adults (9.7%) recalled receiving one dose, 88 (20.7%) two doses, and 101 (23.8%) three doses of the vaccine, but 194 emerging adults (45.8%) did not know. More rural emerging adults who were vaccinated were female, more educated, attended religious services less frequently, had a personal/family history of cancer, were more confident vaccines are safe, and had less constraints on getting vaccinated. More rural emerging adults with multiple vaccine doses were older, female, visited a physician for a routine health check-up more recently, were more confident that vaccines are safe, and had less constraints on getting vaccinated.
Uptake of HPV vaccination among rural emerging adults (52.3%) was slightly higher than the national rate in the 2022 National Health Interview Survey (47.4%). Emerging adults need advice on how to confirm vaccination status (such as checking with parent, physician, or vaccine registry) when promoting catch-up HPV vaccination. HPV vaccination interventions should educate on vaccine safety/ constraints, how it can reduce personal/family cancer concerns, and religious groups that support it. Medical providers should offer HPV vaccination to emerging adults during routine health check-ups. Male and less educated emerging adults would benefit from intervention.

POSTER 2
Title: Associations Between Food Insecurity and Dietary Intake and Nicotine Use Among Rural Emerging Adults in the Western United States

The purpose of the study was to evaluate the associations between food insecurity, dietary intake, and tobacco/nicotine use among emerging adults aged 18-26 years living in rural areas of the western United States.
This analysis used baseline data from 810 rural emerging adults participating in a randomized trial evaluating a social media-delivered cancer prevention intervention. Emerging adults completed self-report surveys assessing demographics, dietary intake (NCI Dietary Screener Questionnaire), and any nicotine product use (yes/no) in the past 30 days. Dietary measures included predicted intake of fruit and vegetable (servings/day), fiber (g/day), added sugar from sugar sweetened beverages (tsp/day), and red/processed meat (frequency/week). Food insecurity was categorized as very low food secure, low food secure, and high food secure from a single item measuring worry about running out of food before having money to buy more. Associations between food insecurity and dietary intake or tobacco/nicotine use were examined using linear or logistic regression models, adjusting for significant demographic covariates. Linear trend tests assessed graded relationships across food insecurity levels.
Of emerging adults (mean age 22.7 years), 62% reported low or very low food security. Food insecurity was associated with race, sex, education, and employment and were used as model covariates. A positive linear trend was observed between food insecurity and added sugar from sugar sweetened beverages, with very low food secure emerging adults consuming an average of 13.0 tsp/day from sugar sweetened beverages. There were no significant associations between food insecurity and fruit and vegetable, fiber, or red/processed meat intake, although fruit and vegetable and fiber intake were low overall (2.3 ± 0.6 servings/day and 15.1 ± 3.4 g/day, respectively). Percent of emerging adults using nicotine was greater with increasing levels of food insecurity: 24% among those with high food security, 41% among those with low food security, and 53% among those with very low food security. Odds increased 2.5 times for each stepwise increase in food insecurity.
Experiencing food insecurity may be a determinant of cancer-preventive health behaviors in rural emerging adults. Very low food security may be an important target for interventions aimed at improving multiple cancer preventive health behaviors among rural emerging adults.
