The association between unhealthy dietary behaviors and participation in the Supplemental Nutrition Assistance Program (SNAP): No evidence in support of the self-selection hypothesis.

Supplemental Nutrition Assistance Program (SNAP) participants tend to have unhealthier dietary consumption compared to eligible non-participants. It has been suggested, though never empirically tested, that individuals who enroll in SNAP may have unhealthy diets prior to program participation. Using a longitudinal cohort study design, we examined the association between low-income adults' SNAP participation status and prior dietary behaviors to test the argument that individuals with unhealthier dietary consumption self-select into SNAP. A sample of households from predominantly lower-income cities were surveyed at baseline (T1) and 2-4 years later (T2). The main analyses were restricted to adults who did not participate in SNAP at T1 and with household income <200% of the federal poverty line (n = 170) at both T1 and T2. Participants were grouped into two categories, based on their SNAP participation at T2; (a) Non-participants (n = 132): no SNAP participation at T1 or T2, and (b) T2 SNAP participants (n = 38): SNAP participation at T2 but not T1. Daily consumption frequency of whole fruits, fruit juice, vegetables, sugar-sweetened beverages (SSBs), and energy dense snacks were measured through self-reports. To observe dietary differences between the two groups prior to SNAP participation, T1 behaviors were compared. There were no significant differences in dietary behaviors at T1 (prior to SNAP participation) between non-participants and T2 participants, providing no evidence of self-selection of individuals with unhealthier dietary consumption into SNAP among our study sample. Improvements in SNAP participants' diets may benefit from focusing on policy changes that encourage healthy dietary habits during participation in the program.

The Association Between Risk Behaviors and Race/Ethnicity on Dental Visiting Among High School Students in Hawai'i: Hawai'i Youth Risk Behavior Survey, 2013, 2015.

Risk behaviors are known to adversely affect health outcomes, but the relationship between youth risk behaviors and oral health remains unclear. The objective of this study is to examine the likelihood of dental visiting among Hawai'i public high school students by demographic factors and number of adverse risk behaviors. Aggregated 2013 and 2015 Hawai'i public high school Youth Risk and Behavior Survey (YRBS) data was analyzed from 10,720 students. Results showed that, overall, 77.1% of students reported a dental visit in the past 12 months. Students who were ages 15, 16, 17, and ≥ 18 years old were less likely than students who were ≤ 14 years old to visit a dentist. Those who identified as Hispanic, Native Hawaiian, Filipino, Other Pacific Islander, and students who identified as more than one race/ethnicity were less likely to visit the dentist than their white counterparts. In addition, students having either 4 risk behaviors or ≥ 5 risk behaviors were less likely to report a dental visit than those with no risk behaviors. These findings support the presence of disparities in oral health care utilization among high school students in Hawai'i and reveal a significant association between age, number of risk behaviors, and race/ethnicity with the likelihood of utilizing dental services. Oral health programs should consider screening for risk factors and multiple risk behaviors, integrating with other health programs that share similar risk behaviors, and account for cultural differences in their development, implementation, and evaluation.
