Item Depression Mediates the Relationship between Food Insecurity and Pain Interference in College Students(2020-12-24) Umeda, Masataka; Ullevig, Sarah L.; Chung, Eunhee; Kim, Youngdeok; Escobedo, Tanya J.; Zeitz, Christopher J.Food insecurity (FI) typically produces unfavorable health conditions. Research shows the high prevalence of FI among college students, and depression is one of the adverse effects of FI among them. It is possible that FI may increase the risk of pain via depression; however, it is currently unclear whether FI is linked to pain among college students. Therefore, this study compared pain experiences between students with and without FI, and examined the relationship between FI, depression, and pain. One hundred seventy-six college students at a Hispanic-serving institution in the southwestern region of US completed self-report measures to assess FI, depression, pain severity, and pain interference. Results indicated that approximately 24% of the students were categorized as food insecure, and those students scored higher on pain interference compared to food-secure students. FI was positively associated with depression and pain interference scores, and depression scores were positively associated with pain interference scores. The mediation analyses based on the counterfactual framework demonstrated a significant mediation effect of depression, where 50.59% of the total effect of FI on pain interference was attributable to the depression. These results suggest that FI extends its negative effects into pain interference among college students, but better management of depression may help alleviate the effects of FI on pain interference.Item Effect of Dietary Geranylgeraniol and Green Tea Polyphenols on Glucose Homeostasis, Bone Turnover Biomarkers, and Bone Microstructure in Obese Mice(2023-01-04) Shen, Chwan-Li; Dufour, Jannette M.; Miranda, Jonathan M.; Kaur, Gurvinder; Chung, Eunhee; Ramalingam, Latha; Moustaid-Moussa, Naima; Cao, Jay J.Previously, we demonstrated that the administration of either geranylgeraniol (GGOH) or green tea polyphenols (GTP) improved bone health. This study examined the combined effects of GGOH and GTP on glucose homeostasis in addition to bone remodeling in obese mice. We hypothesized that GGOH and GTP would have an additive or synergistic effect on improving glucose homeostasis and bone remodeling possibly in part via suppression of proinflammatory cytokines. Forty-eight male C57BL/6J mice were assigned to a high-fat diet (control), HFD + 400 mg GGOH/kg diet (GG), HFD + 0.5% GTP water (TP), or HFD + GGOH + GTP (GGTP) diet for 14 weeks. Results demonstrated that GTP supplementation improved glucose tolerance in obese mice. Neither GGOH nor GTP affected pancreas insulin or bone formation procollagen type I intact N-terminal, bone volume at the lumbar vertebrae, or bone parameters at the trabecular bone and cortical bone of the femur. There was an interactive effect for serum bone resorption collagen type 1 cross-linked C-telopeptide concentrations, resulting in no-GGOH and no-GTP groups having the highest values. GGOH increased trabecular number and decreased trabecular separation at the lumbar vertebrae. GTP increased trabecular thickness at lumbar vertebrae. The GG group produced the greatest connectivity density and the lowest structure model index. Only GTP, not GGOH, decreased adipokines concentrations (resistin, leptin, monocyte chemoattractant protein-1, and interleukin-6). In an obese male mouse model, individual GGOH and GTP supplementation improved glucose homeostasis, serum CTX, and trabecular microstructure of LV-4. However, the combined GGOH and GTP supplementation compromises such osteoprotective effects on serum CTX and trabecular bone of obese mice.Item Gender Differences in the Prevalence of Chronic Pain and Leisure Time Physical Activity Among US Adults: A NHANES Study(2019-03-19) Umeda, Masataka; Kim, YoungdeokGender disparities in chronic pain are well documented in the literature. However, little is known regarding the relationship between physical activity (PA) and gender disparities in chronic pain. This study described gender differences in prevalence of chronic pain and PA, and identified a type of leisure time PA that individuals frequently chose in a nationally representative sample of US adults (N = 14,449). Data from the National Health Nutrition Examination Survey 1999–2004 were analyzed. Individuals were categorized into no chronic pain (NCP), localized chronic pain (LCP), and widespread chronic pain (WCP) groups based on responses to a pain questionnaire. A self-report PA questionnaire was used to estimate the time spent in different types of PA. Women showed higher prevalence of LCP and WCP compared to men. Men spent more hours per week for leisure time PA compared to women, but men and women showed similar prevalence of sufficient PA to meet a PA recommendation (≥150 min/week of moderate-to-vigorous intensity PA) across chronic pain categories. However, the prevalence of sufficient PA was substantially higher among men and women with NCP compared to men and women with LCP and WCP. Additionally, both men and women chose walking as the primary type of leisure time PA. Together, gender disparities exist in the prevalence of chronic pain and hours spent for leisure time PA. More research is needed to explore the role of increasing leisure time PA, such as walking, in reducing gender disparities in chronic pain.Item Geranylgeraniol and Green Tea Polyphenols Mitigate Negative Effects of a High-Fat Diet on Skeletal Muscle and the Gut Microbiome in Male C57BL/6J Mice(2022-09-27) Shen, Chwan-Li; Elmassry, Moamen M.; Grue, Katherine; Joiner, Hayli E.; Jacobo, A. Unique; Hamood, Abdul; Chung, EunheeNatural bioactive compounds are proposed as alternatives in mitigating obesity-associated skeletal muscle dysfunction. The objective of this study was to test the hypothesis that the combination of geranylgeraniol (GGOH) and green tea polyphenols (GTPs) can alleviate high-fat-diet (HFD)-induced muscle atrophy and alter gut microbiome composition. Male C57BL/6J mice fed an HFD were assigned to four groups (12 mice each) in a 2 (no GGOH vs. 400 mg GGOH/kg diet) × 2 (no GTPs vs. 0.5% weight/volume GTPs in water) factorial design. After 14 weeks of diet intervention, skeletal muscle and cecal samples were collected and examined. Compared to the control groups, the group that consumed a combination of GGOH and GTPs (GG + GTPs) had significantly decreased body and fat mass but increased skeletal muscle mass normalized by body weight and cross-sectional area. In soleus muscle, the GG + GTP diet increased citrate synthase activity but decreased lipid peroxidation. Gut microbiome beta-diversity analysis revealed a significant difference in the microbiome composition between diet groups. At the species level, the GG + GTP diet decreased the relative abundance of Dorea longicatena, Sporobacter termitidis, and Clostridium methylpentosum, and increased that of Akkermansia muciniphila and Subdoligranulum variabile. These results suggest that the addition of GGOH and GTPs to an HFD alleviates skeletal muscle atrophy, which is associated with changes in the gut microbiome composition.Item Reliability and Concurrent Validity of Global Physical Activity Questionnaire (GPAQ): A Systematic Review(2019-10-26) Keating, Xiaofen D.; Zhou, Ke; Liu, Xiaolu; Hodges, Michael; Liu, Jingwen; Guan, Jianmin; Phelps, Ashley; Castro-Piñero, JoseThis study aimed to systematically review previous studies on the reliability and concurrent validity of the Global Physical Activity Questionnaire (GPAQ). A systematic literature search was conducted (n = 26) using the online EBSCOHost databases, PubMed, Web of Science, and Google Scholar up to September 2019. A previously developed coding sheet was used to collect the data. The Modified Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies was employed to assess risk of bias and study quality. It was found that GPAQ was primarily revalidated in adult populations in Asian and European countries. The sample size ranged from 43 to 2657 with a wide age range (i.e., 15–79 years old). Different populations yielded inconsistent results concerning the reliability and validity of the GPAQ. Short term (i.e., one- to two-week interval) and long-term (i.e., two- to three-month apart) test–retest reliability was good to very good. The concurrent validity using accelerometers, pedometers, and physical activity (PA) log was poor to fair. The GPAQ data and accelerometer/pedometer/PA log data were not compared using the same measurements in some validation studies. Studies with more rigorous research designs are needed before any conclusions concerning the concurrent validity of GPAQ can be reached.Item Switching to a Standard Chow Diet at Weaning Improves the Effects of Maternal and Postnatal High-Fat and High-Sucrose Diet on Cardiometabolic Health in Adult Male Mouse Offspring(2022-06-18) Chiñas Merlin, Andrea; Gonzalez, Kassandra; Mockler, Sarah; Perez, Yessenia; Jia, U-Ter Aondo; Chicco, Adam J.; Ullevig, Sarah L.; Chung, EunheeCardiac mitochondrial dysfunction contributes to obesity-associated heart disease. Maternal and postnatal diet plays an important role in cardiac function, yet the impacts of a mismatch between prenatal and postweaning diet on cardiometabolic function are not well understood. We tested the hypothesis that switching to a standard chow diet after weaning would attenuate systemic metabolic disorders and cardiac and mitochondrial dysfunction associated with maternal and postnatal high-fat/high-sucrose (HFHS) diet in mice. Six-month-old male CD1 offspring from dams fed a HFHS diet and weaned to the same HFHS diet (HH) or switched to a standard chow diet (HC) were compared to offspring from dams fed a low-fat/low-sucrose diet and maintained on the same diet (LL). HC did not decrease body weight (BW) but normalized glucose tolerance, plasma cholesterol, LDL, and insulin levels compared to the HH. Systolic function indicated by the percent fractional shortening was not altered by diet. In freshly isolated cardiac mitochondria, maximal oxidative phosphorylation-linked respiratory capacity and coupling efficiency were significantly higher in the HC in the presence of fatty acid substrate compared to LL and HH, with modification of genes associated with metabolism and mitochondrial function. Switching to a standard chow diet at weaning can attenuate the deleterious effects of long-term HFHS in adult male mouse offspring.Item The Eyes Have It: Visual Feedback Methods to Make Walking in Immersive Virtual Reality More Accessible for People With Mobility Impairments While Utilizing Head-Mounted Displays(Association for Computing Machinery, 2023-10-22) Mahmud, M. Rasel; Cordova, Alberto; Quarles, JohnThe use of Head-Mounted Displays (HMDs) in Virtual Reality (VR) can cause gait disturbance problems for users because they are unable to see the real world while in VR. This is particularly challenging for individuals with mobility impairments who rely heavily on visual cues to maintain balance. The limited research that has been conducted on this issue has not focused on ways to solve it. IN this study, we investigated how different visual feedback methods affect walking patterns (i.e., gait) in VR. The study involved 50 participants, including 25 individuals with mobility impairments due to multiple sclerosis and 25 without mobility impairments. The participants completed timed walking tasks in both the real world and in VR environments that included various types of visual feedback, such as spatial, static, and rhythmic. The results showed that static and rhythmic visual feedback significantly improved gait performance in VR for people with mobility impairments compared to no visual feedback in VR. The results will help to make more accessible virtual environments for people with mobility impairments.Item The Roles of Perceived Physical Education Competence, Enjoyment, and Persistence on Middle School Students’ Physical Activity Engagement(SAGE Publications, 2023-05-24) Guan, Jianmin; Xiang, Ping; Land, William M.; Hamilton, Xiaofen D.We examined gender and grade differences in the relationship between students’ perceived competence, their enjoyment of physical education (PE), and their PA persistence on the frequency of their physical activity (PA). We also used structural equation modeling to assess the direct, indirect, and total effects of perceived competence and PE enjoyment on PA frequency through the mediator of PA persistence. Participants were 223 middle school students (115 boys, 108 girls) in grades 7 and 8. We found that, regardless of grade level, girls had lower perceived competence and PE enjoyment than boys. Both perceived competence and PE enjoyment had significant direct and positive connections to persistence, but they had no significant indirect effects on PA frequency through the mediator of persistence. These findings highlight the need for physical educators to be aware of gender differences in perceived competence and PE enjoyment, and the important roles these factors have in enhancing students’ PA participation.
