The Moderating Effect Of Socioeconomic Status And Walkability On The Efficacy Of Physical Activity Interventions, Analisa Vavoso, Vincent Berardi, Marc A. Adams

Student Scholar Symposium Abstracts and Posters

To enable physical activity (PA) interventions to better tailor procedures to participant characteristics, we investigated the role of neighborhood socioeconomic status (SES) and walkability on the differential effectiveness of adaptive versus static activity goals (AG vs. SG) and immediate versus delayed (IR vs. DR) reinforcement in a PA trial.

Data was collected as a part of the WalkIT Arizona study, where healthy, inactive adults (n = 512) were instructed to wear an accelerometer daily for one year and were provided with daily goals for moderate-to-vigorous PA (MVPA). The intersection of goal types (adaptive and static) as well as reinforcement types …

Urban-Rural Differences In School Districts' Local Wellness Policies And Policy Implementation Environments, Swati Iyer, Timothy J Walker, Alexandra L Macmillan Uribe, Chad D Rethorst, Rebecca A Seguin-Fowler, Jacob Szeszulski

Journal Articles

Higher rates of obesity in rural compared to urban districts suggest environmental differences that affect student health. This study examined urban-rural differences in districts' local wellness policies (LWPs) and LWP implementation environments. Cross-sectional data from two assessments in Texas were analyzed. In assessment one, each district's LWP was reviewed to see if 16 goals were included. In assessment two, an audit was conducted to identify the presence of a wellness plan (a document with recommendations for implementing LWPs), triennial LWP assessment, and school health advisory councils (SHACs) on the district website. Rural districts' LWPs had a smaller number of total …

Exploring The Associations Between Age Related Decline In Anti-Mullerian Hormone (Amh) And Physical Activity In The All Of Us Research Program, Robert J. Leone, Dr. Paige Coyne, Ze Meng, Dr. Sara Santarossa

Medical Student Research Symposium

Anti-Mullerian Hormone (AMH) is used to measure female fertility levels. Physical activity (PA) has previously been linked to increases in fertility rates. We explored associations between age related decline in AMH and PA, hypothesizing that consistent PA would lead to a lessened decline of AMH levels. This study is a secondary data analysis, sourced from the NIH’s All of Us Research Program database. Inclusion criteria for participant data : a) ≥1 AMH test record in their electronic health records, b) AMH level of < 7ng/ml, and c) ≥30 days of valid Fitbit data within 1 year prior to AMH test date. A series of generalized linear regression models were conducted between normalized AMH level and four different daily average activity intensity minutes based on metabolic equivalents (sedentary, lightly active, fairly active, and very active) and daily step count, adjusting for age at AMH test. The final dataset included 24 participants. Daily average of “very active” minutes had a strong positive effect on lessening the decline of AMH levels (β=0.0159, p=0.136). Two clusters (C1 and C2) were identified by applying the Kmeans method. C1 (N=9) has significantly higher daily “fairly active” minutes (C1: 19.61(8.05) vs C2: 7.59(3.81)) and daily “very active” minutes (C1: 22.81(10.23) vs C2: 8.95(5.12)) compared to C2 (N=15). In an association analysis, C1 AMH level is higher than C2 (0.35(-0.10,1.03), p=0.162. There may be an association between being very active and a preservation of AMH, which could be valuable to providers counseling women prolonging motherhood.
