Direct And Indirect Effects Of Parent Stress On Child Obesity Risk And Added Sugar Intake In A Sample Of Southern California Adolescents, Eleanor Tate Shonkoff, Genevieve F. Dunton, Chih-Ping Chou, Adam M. Leventhal, Ricky Bluthenthal, Mary Ann Pentz

Health Sciences Faculty Publications

Objective Research indicates that children are at higher risk for obesity if their parents have been exposed to a larger number of stressors, yet little is known about effects of parents’ subjective, perceived experience of stress on children’s eating behaviours and adiposity and whether weight-related parenting practices (i.e. parent rules and positive family meal practices) mediate this relationship. The present study evaluated the direct and mediated relationship between parent perceived stress and child waist circumference and parent stress and child consumption of added sugars one year later.

Monitoring Energy Expenditure Using A Multi-Sensor Device—Applications And Limitations Of The Sensewear Armband In Athletic Populations, Karsten Koehler, Clemens Drenowatz

Department of Nutrition and Health Sciences: Faculty Publications

In order to monitor their energy requirements, athletes may desire to assess energy expenditure (EE) during training and competition. Recent technological advances and increased customer interest have created a market for wearable devices that measure physiological variables and bodily movement over prolonged time periods and convert this information into EE data. This mini-review provides an overview of the applicability of the SenseWear armband (SWA), which combines accelerometry with measurements of heat production and skin conductivity, to measure total daily energy expenditure (TDEE) and its components such as exercise energy expenditure (ExEE) in athletic populations. While the SWA has been shown …

Choline Supplementation Normalizes Fetal Adiposity And Reduces Lipogenic Gene Expression In A Mouse Model Of Maternal Obesity, Chauntelle Jack-Roberts, Yaelle Joselit, Khatia Nanobashvili, Rachel Bretter, Olga V. Malysheva, Marie A. Caudill, Anjana Saxena, Kathleen Axen, Ahmed Gomaa, Xinyin Jiang

Publications and Research

Maternal obesity increases fetal adiposity which may adversely affect metabolic health of the offspring. Choline regulates lipid metabolism and thus may influence adiposity. This study investigates the effect of maternal choline supplementation on fetal adiposity in a mouse model of maternal obesity. C57BL/6J mice were fed either a high-fat (HF) diet or a control (NF) diet and received either 25 mM choline supplemented (CS) or control untreated (CO) drinking water for 6 weeks before timed-mating and throughout gestation. At embryonic day 17.5, HF feeding led to higher (p < 0.05) percent total body fat in fetuses from the HFCO group, while the choline supplemented HFCS group did not show significant difference versus the NFCO group. Similarly, HF feeding led to higher (p < 0.05) hepatic triglyceride accumulation in the HFCO but not the HFCS fetuses. mRNA levels of lipogenic genes such as Acc1, Fads1, and Elovl5, as well as the transcription factor Srebp1c that favors lipogenesis were downregulated (p < 0.05) by maternal choline supplementation in the HFCS group, which may serve as a mechanism to reduce fat accumulation in the fetal liver during maternal HF feeding. In summary, maternal choline supplementation improves indices of fetal adiposity in obese dams at late gestation.

Starch-Entrapped Microsphere Fibers Improve Bowel Habit But Do Not Exhibit Prebiotic Capacity In Those With Unsatisfactory Bowel Habits: A Phase I, Randomized, Double-Blind, Controlled Human Trial, Heather E. Rasmussen, Bruce Hamaker, Kumar B. Rajan, Ece Mutlu, Stefan J. Green, Michael Brown, Amandeep Kaur, Ali Keshavarzian

Department of Nutrition and Health Sciences: Faculty Publications

Approximately one-third of individuals in the United States experience unsatisfactory bowel habits, and dietary intake, especially one low in fiber, could be partly responsible. We hypothesized that intake of a fermentable fiber (starch-entrapped microspheres, SM) that has a delayed, slow fermentation profile in vitro would improve bowel habit while exhibiting prebiotic capacity in those with self-described unsatisfactory bowel habits, all with minimal adverse effects. A total of 43 healthy volunteers completed a 3-month,double-blind, parallel-arm randomized clinical trial to assess the ability of a daily dose (9 or 12 g) of SM vs. psyllium (12 g) to improve bowel habit, including …

Fernandez, Ivan Jose Vechetti Jr, Paula P. Freire, Rodrigo W. A. Souza, Rolando A.R. Villacis, Silvia R. Rogatto, Patricia P. Reis, Maeli Dal-Pai-Silvia, Robson F. Carvalho

Department of Nutrition and Health Sciences: Faculty Publications

Cardiac cachexia (CC) is a common complication of heart failure (HF) associated with muscle wasting and poor patient prognosis. Although different mechanisms have been proposed to explain muscle wasting during CC, its pathogenesis is still not understood. Here, we described an integrative analysis between miRNA and mRNA expression profiles of muscle wasting during CC. Global gene expression profiling identified 1,281 genes and 19 miRNAs differentially expressed in muscle wasting during CC. Several of these deregulated genes are known or putative targets of the altered miRNAs, including miR-29a-3p, miR-29b-3p, miR-210-5p, miR-214, and miR-489. Gene ontology analysis on integrative mRNA/miRNA expression profiling …

Objective—The potential influence of dietary factors on inflammation is important for cancer prevention. Utilizing data from control participants (312 men, 911 women) in two nested case-control studies of cancer within the Multiethnic Cohort, we examined the associations of red and processed meat intake with serum levels of leptin, adiponectin, C-reactive protein (CRP), tumor necrosis factor (TNF)-α, and interleukin (IL)-6 and the mediator effect of body mass index (BMI) on the above associations (if present).

Methods—Multivariable linear models were applied to assess the association between red and processed meat intake at cohort entry and serum biomarker levels measured 9.1 …

Formulation, Characterisation And Stability Assessment Of A Food Derived 1 Tripeptide, Leucine-Lysine-Proline Loaded Chitosan Nanoparticles, M.K. Danish, Giuliana Vozza, Hugh Byrne, Jesus Maria Frias, Sinead Ryan

Articles

The chicken or fish derived tripeptide, Leucine-Lysine-Proline (LKP), inhibits the Angiotensin Converting Enzyme and may be used as an alternative treatment for pre-hypertension. However, it has low permeation across the small intestine. The formulation of LKP into a nanoparticle (NP) has the potential to address this issue. LKP-loaded NPs were produced using an ionotropic gelation technique, using chitosan (CL113). Following optimisation of unloaded NPs, a mixture amount design was constructed using variable concentration of CL113 and tripolyphosphate at a fixed LKP concentration. Resultant particle sizes ranged from 120-271 nm, zeta potential values from 29-37 mV and polydispersity values from 0.3-0.6. …

Adaptive Thermogenesis And Metabolic Changes Following Diet- And Exercise- Induced Weight Loss, Alexandra R. Martin

Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research

With more than two-thirds of adults in the United States considered as overweight or obese, a myriad of weight loss programs and products that promise quick results have infiltrated the market. While many individuals successfully lose weight over the short term, almost half of the initial weight lost is regained within one year, indicating a general predisposition for weight cycling and fat replenishment. As weight is lost, fat-free mass (FFM) also decreases, and resting metabolic rate (RMR) declines, decreasing energy expenditure. After accounting for decreases in FFM, there remains a greater-than- predicted decrease in RMR, referred to as adaptive thermogenesis …

Relationships Between Nutrition-Related Knowledge, Self-Efficacy, And Behavior For Fifth Grade Students Attending Title I And Non-Title I Schools, Elisha M. Hall, Weiwen Chai, Julie A. Albrecht

Department of Nutrition and Health Sciences: Faculty Publications

The Social Cognitive Theory (SCT) is a widely used theory for nutrition education programming. Better understanding the relationships between knowledge, self-efficacy, and behavior among children of various income levels can help to form and improve nutrition programs, particularly for socioeconomically disadvantaged youth. The purpose of this study was to determine the relationships between knowledge, self-efficacy, and behavior among fifth grade students attending Title I (≥ 40% of students receiving free or reduced school meals) and non-Title I schools (< 40% of students receiving free or reduced school meals). A validated survey was completed by 55 fifth grade students from Title I and 122 from non-Title I schools. Differences in knowledge, self-efficacy, and behavior scores between groups were assessed using t test and adjusted for variations between participating schools. Regression analysis was used to determine the relationships between knowledge, self-efficacy, and behavior. In adjusted models, the Title I group had significantly lower scores on several knowledge items and summary knowledge (P = 0.04). The Title I group had significantly lower scores on several behavior variables including intakes of fruits (P = 0.02), vegetables (P = 0.0005), whole grains (P = 0.0003), and lean protein (P = 0.047), physical activity (P = 0.002) and summary behavior (P = 0.001). However the Title I group scored higher on self-efficacy for meal planning (P = 0.04) and choosing healthy snacks (P = 0.036). Both self-efficacy (β = 0.70, P < 0.0001) and knowledge (β = 0.35, P = 0.002) strongly predicted behavior; however, only self-efficacy remained significant in the Title I group (self-efficacy, β = 0.82, P = 0.0003; knowledge, β = 0.11, P = 0.59). Results demonstrate disparities in nutrition knowledge and behavior outcomes between students surveyed from Title I and non-Title I schools, suggesting more resources may be necessary for lower income populations. Findings suggest that future nutrition interventions should focus on facilitating the improvement of children's self-efficacy

Department of Nutrition and Health Sciences: Faculty Publications

Athyrium multidentatum (Doll.) Ching (AMC), a unique and nutritious potherb widely distributed in china, has been extensively used in traditional Chinese medicine. Previous studies indicated that AMC extract exhibited antioxidant and antitumor properties. However, the chemical composition of AMC and molecular mechanism of AMC toxicity to HepG2 cells have not yet been elucidated. Hence, this study aimed to investigate the chemical compositions and the underlying mechanisms of the antiproliferative and apoptotic effects of AMC on HepG2. HPLC-MS analysis showed that AMC contain five compounds with chlorogenic acid accounting for 43 percent. Also, AMC strongly inhibited the cell growth and induced …

Optimal Nutrition For Endurance Exercise: A Systematic Review, Sarah E. Andrus Ms, Bruce W. Andrus Md Ms

Dartmouth Scholarship

Introduction

As fatigue in endurance events correlates with depletion of muscle glycogen, the traditional approach to nutritional support has been carbohydrate loading. However, there has been recent interest in improving athletic endurance performance by novel diets in the days to weeks prior to endurance events, the pre-event meal, and during exercise.

Methods

We searched PubMed and SCOPUS for randomized trials published from 1992-2017 with a primary endpoint of endurance performance. We identified 407 citations which were examined against our inclusion criteria of randomization or crossover allocation to diet and for which a primary outcome was endurance performance.

The pathogenesis of atopic dermatitis (AD) is complex and related to allergic responses and defects in skin barrier function. In common with many atopic diseases, the prevalence of AD has been increasing across the world.1 One of the theories for this increase is increased hygiene and urbanization-related changes in the environment, which can affect the human microbiome.2 Previous studies have found associations between the composition of the early gut microbiome and development of atopic conditions, including AD.3 Although the rate of atopic conditions, including AD and food allergy, is increasing on all continents, the prevalence of these diseases is still …

Lactose Intolerance: An Overview Of The Facts And Their Implications, Noelle M. Yeo

Honors Theses

Lactose intolerance is often blamed for the symptoms such as bloating, diarrhea, gas, abdominal pain, and nausea, that ail many people. Patients often do not seek proper diagnosis from a physician and create their own treatment plans, severely restricting lactose intake, without professional guidance. Even those who do seek the care of a physician find that diagnosis is complicated by less-than ideal testing and confusion due to the symptoms common to many other conditions. The misconceptions and inability to confirm a diagnosis of lactose intolerance can cause nutrient deficiencies in these patients, as well as begin a pattern of unnecessary …

Nonprofit Pay In A Competitive Market: Wage Penalty Or Premium?, Christian King, Gregory B. Lewis

Department of Nutrition and Health Sciences: Faculty Publications

Two competing theories argue that the nonprofit sector pays differently: Nonprofit employees may accept lower pay to be able to do meaningful work for a good cause, or they may earn higher pay due to nonprofit organizations’ tax exemptions and weaker incentives to hold down wages. To test these opposing expectations, we use the 2005-2013 American Community Surveys to examine pay differences among registered nurses working for nonprofit, for-profit, and public hospitals. We also test hypotheses that public and nonprofit hospitals have smaller pay disparities by gender, race, and relationship status. We find that pay is highest in nonprofit hospitals, …

Healthy Eating: How Do We Define It And Measure It? What’S The Evidence?, Christy C. Tangney, Beth A. Staffileno, Heather Rasmussen

Department of Nutrition and Health Sciences: Faculty Publications

A healthy diet can be defined in many ways, including defining one’s food intake by a dietary pattern. As described in the Dietary Guidelines for Americans Committee report, there are several defined dietary patterns associated with lower rates of chronic diseases. These include the Healthy Eating Index, Dietary Approach to Stop Hypertension, and those based on the Mediterranean diet. This review will focus on guiding health care professionals, including nurse practitioners, how a healthy diet pattern is defined, how it is measured, and a summary of recent evidence supporting the healthfulness of these dietary patterns.

Evaluation Of A Dietary Screener: The Mediterranean Eating Pattern For Americans Tool, L. A. Cerwinske, Heather Rasmussen, S. Lipson, A. S. Volgman, Christy C. Tangney

Department of Nutrition and Health Sciences: Faculty Publications

Background: Evidence exists for an association between accordance with a Mediterranean diet pattern and slower rates of cognitive decline. However, an ‘Americanized’ version of the Mediterranean diet screener is needed to assess accordance in the USA. Thus, the Mediterranean Eating Pattern for Americans (MEPA) tool was developed to assess accordance with a Mediterranean-like food pattern when time is limited. The present study aimed to determine whether the MEPA screener captured the key elements of the Mediterranean diet compared to the more comprehensive food frequency questionnaire (FFQ).

Methods: The study comprised a cross-sectional study in which 70 women completed both the …

Plasma membrane (PM) free cholesterol (FC) is emerging as an important modulator of signal transduction. Here, we show that hepatocyte-specific knockout (HSKO) of the cellular FC exporter, ATPbinding cassette transporter A1 (ABCA1), leads to decreased PM FC content and defective trafficking of lysosomal FC to the PM. Compared with controls, chow-fed HSKO mice had reduced hepatic (1) insulin- stimulated Akt phosphorylation, (2) activation of the lipogenic transcription factor Sterol Regulatory Element Binding Protein (SREBP)-1c, and (3) lipogenic gene expression. Consequently, Westerntype diet-fed HSKO mice were protected from steatosis. Surprisingly, HSKO mice had intact glucose metabolism; they showed normal gluconeogenic gene …

Diet can influence the composition of the human microbiome, and yet relatively few dietary ingredients have been systematically investigated with respect to their impact on the functional potential of the microbiome. Dietary resistant starch (RS) has been shown to have health benefits, but we lack a mechanistic understanding of the metabolic processes that occur in the gut during digestion of RS. Here, we collected samples during a dietary crossover study with diets containing large or small amounts of RS. We determined the impact of RS on the gut microbiome and metabolic pathways in the gut, using a combination of “omics” …
