Item Addressing Food Insecurity: Lessons Learned from Co-Locating a Food Pantry with a Federally Qualified Health Center(Ubiquity Press, 2022-09-30) Reinoso, Deanna; Haut, Dawn; Claffey, Stephen; Hahn Keiner, Kathy; Chavez, Alejandra; Nace, Nicole; Carter, Amy; Pediatrics, School of MedicineIntroduction: Social determinants of health, such as food insecurity, contribute to chronic health conditions, decreased quality of life, and health disparities. Increasingly, healthcare systems seek to address social determinants of health by integrating medical and social care. Description: Eskenazi Health Center Pecar is a Federally Qualified Health Center providing comprehensive primary care to vulnerable patients in Indianapolis, IN, USA. This health center, in coalition with community partners, established and continually developed an integrated food pantry model to address food insecurity, improve nutrition education, and support patient access to healthy food. Discussion: Food insecurity and poor nutrition are common in primary care and contribute to the incidence and outcomes of chronic conditions such as obesity, hypertension, and diabetes. Long-term management of food assistance and nutrition programs requires substantial resources, partnerships, and leadership. We describe lessons learned in food pantry partnership, funding, logistics, and sustainability in a collaborative food access model integrated into healthcare. These lessons learned can be utilized by other health systems to scale up and accelerate strategies to better address food security and nutrition education. This paper articulates best practices for integrating a food pantry model within primary care with the goal of long-term sustainability and direct impact on patient health outcomes.Item Association of Self-Efficacy and Self-Regulation with Nutrition and Exercise Behaviors in a Community Sample of Adults(Taylor and Francis, 2015-11) Shieh, Carol; Weaver, Michael T.; Hanna, Kathleen M.; Newsome, Kathleen; Mogos, Mulubrhan; IU School of NursingThis study examined the association of self-efficacy and self-regulation with nutrition and exercise behaviors. The study used a cross-sectional design and included 108 participants (54 men, 54 women). Nutrition behaviors (fruit/vegetable consumption, dinner cooking, and restaurant eating) and exercise were measured using total days in last week a behavior was reported. Instruments measuring self-efficacy and self-regulation demonstrated excellent Cronbach’s alphas (.93–.95). Path analysis indicated only fruit/vegetable consumption and exercise were associated with self-efficacy and self-regulation. Self-regulation showed direct association with fruit/vegetable consumption and exercise, but self-efficacy had direct association only with exercise. Self-efficacy and self-regulation should be strategically used to promote health behaviors.Item Association of Vitamin E Intake at Early Childhood with Alanine Aminotransferase Levels at Mid-Childhood(Wiley, 2017) Woo Baidal, Jennifer A.; Cheng, Erika R.; Rifas-Shiman, Sheryl L.; Oken, Emily; Gillman, Matthew W.; Taveras, Elsie M.; Pediatrics, School of MedicineThe extent to which vitamin E (alpha-tocopherol) intake early in childhood is associated with alanine aminotransferase (ALT) level later in childhood is unknown. The objective of this research is to test the hypothesis that higher alpha-tocopherol intake during early childhood is associated with lower odds of elevated ALT levels during mid-childhood, and to examine how body mass index (BMI) influences these relationships. We studied 528 children in Project Viva. Mothers reported child dietary intake at early childhood visits (median 3.1 years) using a validated food frequency questionnaire. At mid-childhood (median 7.6 years), we collected child blood and anthropometric data. The main outcome was elevated sex-specific mid-childhood ALT level (≥ 22.1 units/liter for females and ≥ 25.8 units/liter for males). In multivariable logistic regression models, we assessed the association of energy-adjusted alpha-tocopherol intake with ALT levels, adjusting for child age, sex, race/ethnicity, diet, and age-adjusted, sex-specific BMIz at mid-childhood. Among children in this study, 48% were female, 63% were non-Hispanic white, 19% were non-Hispanic black, and 4% Hispanic/Latino. Mean alpha-tocopherol intake was 3.7±1.0 mg/day (range 1.4-9.2) at early childhood. At mid-childhood, mean BMIz was 0.41±1.0 units and 22% had an elevated ALT level. In multivariable-adjusted logistic regression models, children with higher early childhood vitamin E intake had lower odds of elevated mid-childhood ALT [adjusted odds ratio (AOR) 0.62 (95% CI: 0.39-0.99)] for quartiles 2-4 compared with the lowest quartile of intake. Findings persisted after accounting for early childhood diet [0.62 (0.36, 1.08)] and were strengthened after additionally accounting for mid-childhood BMIz [0.56 (0.32, 0.99)]. Conclusion: In this cohort, higher early childhood intake of alpha-tocopherol was associated with lower odds of elevated mid-childhood ALT level.Item Associations between Two Dietary Quality Scores and Pancreatic Cancer Risk in a US National Prospective Cohort Study(Taylor & Francis, 2024) Hoyt, Margaret; Song, Yiqing; Gao, Sujuan; O'Palka, Jacquelynn; Zhang, Jianjun; Biostatistics and Health Data Science, Richard M. Fairbanks School of Public HealthObjective Most previous studies investigated the associations between intake of individual nutrients and risk of disease, which failed to consider the potential interactions and correlations between various nutrients contained in food. Although dietary quality scores provide a comprehensive evaluation of the entire diet, it remains elusive whether they are associated with the risk of pancreatic cancer. Methods Dietary intake data collected with the Dietary Questionnaire (DQX) and Diet History Questionnaire (DHQ) were used to calculate HEI-2015 and DQI-R scores for participants in the Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial. A high score indicates an increased intake of adequacy components and a decreased intake of moderation components. This study included 252 cases of pancreatic cancer documented from 58,477 persons during a median follow-up of 12.2 years in the DQX cohort and 372 cases of pancreatic cancer ascertained from 101,721 persons during a median follow-up of 8.9 years in the DHQ cohort. Cox proportional hazards regression analysis was performed to calculate hazard ratios (HR) and 95% confidence intervals (CI) for the associations between the two dietary quality scores and pancreatic cancer risk. Results After adjustment for confounders, HEI-2015 and DQI-R scores were not significantly associated with pancreatic cancer risk. However, a significantly lower risk was observed for overweight persons with a higher HEI-2015 score in the DQX cohort (HR [95% CI] comparing the highest with lowest tertile: 0.52 [0.32, 0.85], p for trend = 0.009) and those with higher scores of some individual components. Conclusion Collectively, overall dietary quality is not associated with an altered risk of pancreatic cancer in this US population.Item Effects of biscuit-type feeding supplementation on the neurocognitive outcomes of HIV-affected school-age children: a randomized, double-blind, controlled intervention trial in Kenya(Compuscript, 2017-12-01) Khee Loo, Kek; Rizzo, Shemra; Chen, Qiaolin; Weiss, Robert E.; Sugar, Catherine A.; Ettyang, Grace; Ernst, Judith; Samari, Goleen; Neumann, Charlotte G.; Health Sciences, School of Health and Rehabilitation SciencesObjective: To determine if meat or soy protein dietary supplementation will enhance the neurocognitive performance of HIV-affected children at-risk of malnutrition and food insecurity. Methods: A randomized, double-blind, controlled intervention trial evaluated the effect of nutritional supplementation on the neurocognitive outcomes of 49 HIV-affected school-age children in western Kenya. The intervention consisted in providing the mother, target child, and siblings with one of three isocaloric biscuit-type supplements – soy, wheat, or beef – on 5 days per week for 18 months. Neurocognitive outcomes of the target children were assessed by a battery of eight measures and followed up longitudinally for up to 24 months. Results: Mixed effects modeling demonstrated significant differences in the rates of increase over time among all three groups (F test degrees of freedom of 2, P<0.05) for Raven’s progressive matrices performance, but not for verbal meaning, arithmetic, digit span backward, forward, and total, embedded figure test, and Beery visual–motor integration scores. Conclusion: HIV-affected school-age children provided with soy protein supplementation showed greater improvement in nonverbal cognitive (fluid intelligence) performance compared with peers who received isocaloric beef or wheat biscuits. Soy nutrients may have an enhancing effect on neurocognitive skills in HIV-affected school-age childrenItem Feeding Outcomes for Infants with Bronchopulmonary Dysplasia Discharged on Nasogastric Feeds(Thieme, 2019) Matharu, Preet; Cristea, A. Ioana; Slaven, James E.; Becker, Samantha; Niehaus, Jason Z.; Pediatrics, School of MedicineObjective While previous studies regarding neonatal home feeding regimens have demonstrated a more favorable prognosis for nasogastric (NG) versus gastrostomy tubes (GT), institutional practices of discharge on NG feeds are varied, particularly for infants with bronchopulmonary dysplasia (BPD). Little is known regarding the risk factors for patients treated with GT postdischarge in premature infants with BPD. Our objective was to identify frequency and risk factors for treating premature infants with BPD discharged on NG feeds with GT. Study Design In this retrospective study, we included infants born at 30 weeks’ gestational age with BPD transitioning from a tertiary care center to home on NG feeds from 2010 to 2016. Results Of the 86 infants included in this study, 25 (29%) underwent GT placement at a median age of 264 days postdischarge. Fourteen (56%) were able to remove the GT at a median age of 979.5 days. Infants not requiring GT placement postdischarge were found to have a significantly higher ccipitofrontal circumference (p = 0.0089) and length (p = 0.0166) at discharge compared with infants with GT. Conclusion NG feeding for infants with BPD appears to be a viable treatment with fewer patients (29%) requiring GT placement. Gestational age and abnormal magnetic resonance imaging results were found to have a significant association with GT placement postdischarge.Item High‐dose Cholecalciferol Supplementation in Adults with Cystic Fibrosis(Wiley, 2019-09) Janzen, Kristin M.; Sakon, Colleen; Lehman, Angela; Sommer, Bekah; Brown, Cynthia; Medicine, School of MedicineIntroduction Despite the availability of consensus guidelines for the treatment of vitamin D deficiency, prospective trials are lacking to examine alternative dosing strategies for adult patients with cystic fibrosis (CF) who do not meet therapeutic goals with standard regimens. Objectives The primary objective of this study was to determine the efficacy of high‐dose cholecalciferol supplementation in increasing serum vitamin D (25‐OHD) levels in adult patients with CF. Methods Patients were eligible for inclusion if they were 18 years or older, had baseline 25‐OHD levels lower than 30 ng/ml, and were diagnosed with CF and pancreatic insufficiency. Patients were given a single dose of cholecalciferol 300,000 or 500,000 IU based on baseline 25‐OHD levels. Response was defined by 25‐OHD and ionized calcium levels at 3 months. At 6 months, responders received a second dose of the same strength, and nonresponders were given a weekly supplement of cholecalciferol 50,000 IU in addition to cholecalciferol 500,000 IU. A second 25‐OHD level was obtained at 9 months. Results Of the 46 patients enrolled, 32 patients (70%) completed the study. Baseline levels of 25‐OHD significantly increased over time in the per protocol population at 3 and 9 months. A total of 16 patients (50%) were considered nonresponders and required weekly supplementation. Conclusion A protocol using high‐dose cholecalciferol or high‐dose plus weekly cholecalciferol is safe and effective in treating adult patients with CF and pancreatic insufficiency.Item Iron deficiency and high-intensity running interval training do not impact femoral or tibial bone in young female rats(Cambridge University Press, 2022-10-28) Scott, Jonathan M.; Swallow, Elizabeth A.; Metzger, Corinne E.; Kohler, Rachel; Wallace, Joseph M.; Stacy, Alexander J.; Allen, Matthew R.; Gasier, Heath G.; Anatomy, Cell Biology and Physiology, School of MedicineIn the US, as many as 20% of recruits sustain stress fractures during basic training. In addition, approximately one-third of female recruits develop iron deficiency upon completion of training. Iron is a cofactor in bone collagen formation and vitamin D activation, thus we hypothesized iron deficiency may be contributing to altered bone microarchitecture and mechanics during 12-weeks of increased mechanical loading. Three-week old female Sprague Dawley rats were assigned to one of four groups: iron adequate sedentary, iron deficient sedentary, iron adequate exercise, and iron deficient exercise. Exercise consisted of high-intensity treadmill running (54 min 3×/week). After 12-weeks, serum bone turnover markers, femoral geometry and microarchitecture, mechanical properties and fracture toughness, and tibiae mineral composition and morphometry were measured. Iron deficiency increased the bone resorption markers C-terminal telopeptide type I collagen and tartate-resistant acid phosphatase 5b (TRAcP 5b). In exercised rats, iron deficiency further increased bone TRAcP 5b, while in iron adequate rats, exercise increased the bone formation marker procollagen type I N-terminal propeptide. In the femur, exercise increased cortical thickness and maximum load. In the tibia, iron deficiency increased the rate of bone formation, mineral apposition, and zinc content. These data show that the femur and tibia structure and mechanical properties are not negatively impacted by iron deficiency despite a decrease in tibiae iron content and increase in serum bone resorption markers during 12-weeks of high-intensity running in young growing female rats.Item Kidney Disease Progression Does Not Decrease Intestinal Phosphorus Absorption in a Rat Model of Chronic Kidney Disease–Mineral Bone Disorder(Wiley, 2019) Vorland, Colby J.; Biruete, Annabel; Lachcik, Pamela J.; Srinivasan, Shruthi; Chen, Neal X.; Moe, Sharon M.; Gallant, Kathleen M. Hill; Medicine, School of MedicineThe Cy/+ rat has been characterized as a progressive model of chronic kidney disease–mineral bone disorder (CKD‐MBD). We aimed to determine the effect of kidney disease progression on intestinal phosphorus absorption and whole‐body phosphorus balance in this model. A total of 48 Cy/+ (CKD) and 48 normal littermates (NL) rats were studied at two ages: 20 weeks and 30 weeks, to model progressive kidney function decline at approximately 50% and 20% of normal kidney function. Sodium‐dependent and sodium‐independent intestinal phosphorus absorption efficiency were measured by the in situ jejunal ligated loop method using 33P radioisotope. Our results show that CKD rats had slightly higher sodium‐dependent phosphorus absorption compared to NL rats, and absorption decreased from 20 to 30 weeks. These results are in contrast to plasma 1,25OH2D, which was lower in CKD rats. Gene expression of the major intestinal phosphorus transporter, NaPi‐2b, was not different between CKD and NL rats in the jejunum but was lower in CKD rats versus NL rats in the duodenum. Jejunal ligated loop phosphorus absorption results are consistent with percent net phosphorus absorption results obtained from metabolic balance: higher net percent phosphorus absorption values in CKD rats compared with NL, and lower values in 30‐week‐olds compared with 20‐week‐olds. Phosphorus balance was negative (below zero) in CKD rats, significantly lower in 30‐week‐old rats compared with 20‐week‐old rats, and lower in CKD rats compared with NL rats at both ages. These results demonstrate no reduction in intestinal phosphorus absorption with progression of CKD despite lower 1,25OH2D status when assessed by an in situ ligated loop test, which is in contrast to the majority of in vitro studies, and if confirmed in further studies, could challenge the physiological relevance of in vitro findings.Item Long-Term Follow-up of Hypophosphatemic Bone Disease Associated With Elemental Formula Use: Sustained Correction of Bone Disease After Formula Change or Phosphate Supplementation(Sage, 2020-10) Eswarakumar, Abigail S.; Ma, Nina S.; Ward, Leanne M.; Backeljauw, Philippe; Wasserman, Halley; Weber, David R.; DiMeglio, Linda A.; Imel, Erik A.; Gagne, Julie; Cody, Declan; Zimakas, Paul; Swartz Topor, Lisa; Agrawal, Sungeeta; Calabria, Andrew; Tebben, Peter; Faircloth, Ruth; Gordon, Rebecca; Casey, Linda; Carpenter, Thomas O.; Pediatrics, School of MedicineIn this article, we describe the long-term outcomes of children who were previously reported to have developed hypophosphatemic bone disease in association with elemental formula use. An extended chart review allowed for an updated report of 34 children with regard to severity/duration of bone disease, extent of recovery, and time to correction using radiology reports and biochemical data. After implementation of formula change and/or phosphate supplementation, we found that serum phosphorus concentration increased and serum alkaline phosphatase activity decreased in all patients, normalizing by 6.6 ± 4.0 (mean ± SD) months following diagnosis. The decrease in serum alkaline phosphatase from diagnosis to the time of correction was moderately correlated with the concurrent increase in serum phosphorus (R = 0.48, P < .05). Age at diagnosis significantly correlated with time to resolution (R = 0.51, P = .01). This study supports the earlier report that bone disease associated with hypophosphatemia during elemental formula use responds to formula change and/or phosphate supplementation.
