How Are Women Dealing With Polycystic Ovary Syndrome?, Adrianna A. Brown

Electronic Theses, Projects, and Dissertations

Background and Aims: PCOS is one of the leading multisystem conditions among women of reproductive age. Dietary changes may help improve outcomes associated with PCOS and its comorbidities. While a lower carbohydrate, moderate protein diet is often recommended, those with PCOS often use temporary diets or dietary supplements instead of or in addition to prescription medications due to dissatisfaction with their treatment options. Additionally, studies examining the usefulness of supplements and their effects on PCOS symptoms are lacking. This study explored the prevalence of use of temporary diets, prescription medications, and dietary supplements among women with PCOS.

Methods: An anonymous …


The Role Of Top-Down Appetite Self-Regulation In The Development Of Healthy Eating Behaviors Among Children: A Narrative Review And Socialization Framework, David J Bridgett, Sheryl O Hughes, Matthew Broussard, Daniela Mccourt, Christina M Croce, Jennifer O Fisher Mar 2026

The Role Of Top-Down Appetite Self-Regulation In The Development Of Healthy Eating Behaviors Among Children: A Narrative Review And Socialization Framework, David J Bridgett, Sheryl O Hughes, Matthew Broussard, Daniela Mccourt, Christina M Croce, Jennifer O Fisher

Children’s Nutrition Research Center Staff Publications

Appetite self-regulation (ASR) among children is thought to have a fundamental role in shaping the development of healthy eating behaviors, dietary intake, and growth during childhood. Parallel to developmental frameworks for understanding "general" self-regulation among children, ASR has been described as involving children's use of "top-down" cognitive processes to moderate "bottom-up" biological drives around food approach and avoidance in the interest of achieving desired eating behaviors or outcomes. Whereas bottom-up ASR processes during early childhood are well characterized, particularly in the context of dysregulation and obesity risk, the role of top-down ASR processes in the development of healthy eating behaviors …

Nutrition epidemiological models involve many analytic decisions, such as defining exposures, selecting which covariates to include, or configuring variables in different ways. We explored the impact of analytical decisions on conclusions in nutrition epidemiology using self-reported beef intake and incident coronary heart disease as a case study. We used REasons for Geographic and Racial Differences in Stroke (REGARDS) data, and selected covariates and their configurations from published literature to recapitulate common models used to assess associations between meat intake and health outcomes. Three model sets were designed: sets one and two used continuous and quintile-defined beef intakes, respectively, each with …

The essentiality of protein in the human diet is unequivocal. Yet researchers, clinicians, and lay people often believe numerous propositions about dietary protein despite insufficient supporting or refuting data in some instances. To address this disconnect, and to "pressure-test" current beliefs about dietary protein, the Indiana University School of Public Health-Bloomington convened a workshop in February 2025 titled "Human Dietary Protein Needs and Benefits: A Critical Assessment of Postulated Propositions." More than 20 international experts discussed (1) methodologic issues affecting data acquisition and interpretation; (2) "optimal" dietary protein intakes and effects on muscle protein synthesis rates, muscle protein accretion, …

Tall Orders: A Comparison Of Resident Food Behaviours By Dwelling Type And Apartment Characteristics In Australia, Joelie Mandzufas, Siobhan Hickling, Kevin Murray, Sarah Foster, Gina S.A. Trapp

Research outputs 2022 to 2026

To accommodate population growth, Australian cities are becoming denser, with more Australians living in apartments. However, there is little understanding of whether this shift towards apartment living raises any potential short- and long-term implications for dietary health. Using an Australian nationally representative household survey, this cross-sectional study compared meal-purchasing frequency and fruit and vegetable intake by dwelling type, apartment block height, and number of bedrooms in the apartment. Adjusted mean differences were derived from linear regressions, adjusting for socio-demographic characteristics. Apartment residents purchased 0.72 more meals out each week than house residents (p < 0.001, 95% CI [0.599,0.831]) and consumed 0.10 fewer daily serves of vegetables (p = 0.002, 95% CI [0.038,0.163]). Among apartment residents, those in high-rise blocks purchased 0.80 more meals out each week than low-rise residents (p = 0.012, 95% CI [0.250,1.348]), and residents of one-bedroom or studio apartments ate 0.25 fewer serves of fruit per day than residents in apartments with at least three bedrooms (p = 0.003, 95% CI [0.038,0.163]). These findings provide important evidence to inform policy and targeted interventions that promote healthy food behaviours in apartment-living populations.

Children’s Nutrition Research Center Staff Publications

Objectives: Sleep-disordered breathing (SDB) and diet quality impact cardiometabolic disease, but few studies have examined if SDB influences diet quality. This study estimated the association between SDB subtypes (with and without sleepiness) and future diet quality in the Multi-Ethnic Study of Atherosclerosis.

Methods: Probable SDB was characterized by self-reported physician-diagnosed sleep apnea (PDSA) or habitual snoring and subtyped by presence or absence of sleepiness. A food frequency questionnaire measured diet 1.6 years before, and 7.8 years after SDB assessment. Diet quality was measured with the Alternate Healthy Eating Index-2010 (AHEI). Mean differences in AHEI at follow-up by SDB subtypes were …

Randomised controlled trials in nutrition (RCTN) face unique challenges, including the considerable influence of the background diet and the challenge of assuring intervention adherence by participants. The impact of these factors on the outcome of RCTNs has been difficult to quantify, but nutritional biomarkers represent a valuable tool to address these challenges. Using flavanols as a model dietary intervention and a set of recently validated flavanol biomarkers, we here investigated the impact of background diet and adherence on the outcomes of a subcohort of the COcoa Supplement and Multivitamin Outcomes Study (COSMOS, NCT 02422745). We found that 20% of participants …

Children’s Nutrition Research Center Staff Publications

Background/objectives: Diet quality and sleep regularity both influence cardiovascular disease (CVD) risk and may influence each other, but there is scarce evidence for their joint or interacting associations in relation to CVD. We assessed these associations in the Multi-Ethnic Study of Atherosclerosis (MESA).

Methods: Participants free of CVD with valid diet and sleep measures in 2010-2013 were included and followed through 2020 for detection of incident CVD (188 events detected over 8.8 years among 1782 participants; 55% women). Sleep timing and duration regularity were assessed via the intra-individual SD of sleep onset time and duration across 5- to 7-day actigraphy. …


Exploring The Relationship Between Diet And Mental Health, Emory Layne May 2025

Exploring The Relationship Between Diet And Mental Health, Emory Layne

Honors Theses

Dietary patterns in Western societies have shifted over the past century due to the rise of food manufacturing and technological advancements. Ultra-processed foods now account for approximately half of the daily energy intake in high-income countries. Similarly, the national mental health crisis emerged in the 21st century and worsened after the COVID-19 pandemic. The changes in diet have impacted the gut microbiome, which interacts with the brain through the bidirectional gut-brain axis. Research suggests the concept of the gut-brain axis is a principal indicator of diet’s impact on mental health. However, this area of research is still emerging and requires …

The Small Gtpase Rap1 In Pomc Neurons Regulates Leptin Actions And Glucose Metabolism, Kentaro Kaneko, Weisheng Lu, Yong Xu, Alexei Morozov, Makoto Fukuda

Faculty, Staff and Students Publications

The hypothalamic leptin-proopiomelanocortin (POMC) pathway is critical for regulating metabolism. POMC neurons in the arcuate nucleus respond to leptin and play a pivotal role in mediating energy and glucose balance. However, during diet-induced obesity (DIO), these neurons often develop resistance to exogenous leptin. Recently, the small GTPase Rap1 has been implicated as an inhibitor of neuronal leptin signaling; however, its specific role within POMC neurons remains unexplored. We generated tamoxifen-inducible, POMC neuron-specific Rap1 knockout mice to selectively delete both Rap1a and Rap1b isoforms in POMC neurons. By analyzing these mice through metabolic phenotyping, immunohistochemistry, and biochemical assays, we show that …


The Impact Of Energy Intake And Macronutrient Distribution On Recovery Rates In Young Women With Functional Hypothalamic Amenorrhea, Hadley Day, Rebecca Lyons, Taylor Vas Apr 2025

The Impact Of Energy Intake And Macronutrient Distribution On Recovery Rates In Young Women With Functional Hypothalamic Amenorrhea, Hadley Day, Rebecca Lyons, Taylor Vas

Department of Nutrition Student Projects

Functional hypothalamic amenorrhea (FHA) is characterized by irregular or absent menstrual cycles due to disturbances in the hypothalamic-pituitary-ovarian (HPO) axis. Young women ages 18-25 are particularly vulnerable to FHA, which can have long-term consequences on bone health, fertility, and overall well-being. While meeting energy needs is essential for recovery, the question arises of whether different macronutrient distributions within an energy-sufficient diet influence the recovery rate. This study aims to evaluate the impact of varying macronutrient compositions on the recovery of young women with FHA. The study will be conducted using a randomized controlled trial design to examine whether diets with …

Industrialization adversely affects the gut microbiome and predisposes individuals to chronic non-communicable diseases. We tested a microbiome restoration strategy comprising a diet that recapitulated key characteristics of non-industrialized dietary patterns (restore diet) and a bacterium rarely found in industrialized microbiomes (Limosilactobacillus reuteri) in a randomized controlled feeding trial in healthy Canadian adults. The restore diet, despite reducing gut microbiome diversity, enhanced the persistence of L. reuteri strain from rural Papua New Guinea (PB-W1) and redressed several microbiome features altered by industrialization. The diet also beneficially altered microbiota-derived plasma metabolites implicated in the etiology of chronic non-communicable diseases. Considerable …

PURPOSE OF REVIEW: Hypertension (HTN) is a major risk factor for cardiovascular diseases (CVD). The global prevalence of HTN and related CVD mortality continues to rise. The development of HTN is influenced by genetic predisposition and modifiable risk factors, including diet. One area of ongoing debate is the relationship between red meat consumption and risk of HTN.

RECENT FINDINGS: Processed red meat has become increasingly implicated in the pathogenesis and morbidity of HTN, though randomized control trials comparing HTN-related outcomes associated with red meat subtypes have yielded heterogenous results. This review summarizes the existing relevant literature and highlights the methodological …

Background: Dairy consumption has been associated with various health outcomes that may be mediated by changes in gut microbiota.

Methods: This cross-sectional study investigated the association between the colonic mucosa-associated gut microbiota and the self-reported intake of total dairy, milk, cheese, and yogurt. A total of 97 colonic mucosal biopsies collected from 34 polyp-free individuals were analyzed. Dairy consumption in the past year was assessed using a food frequency questionnaire. The 16S rRNA gene V4 region was amplified and sequenced. Operational taxonomic unit (OTU) classification was performed using the UPARSE and SILVA databases. OTU diversity and relative abundance were compared …

BACKGROUND/OBJECTIVES: Persons with multiple sclerosis (MS) are interested in diet as a second-line approach for disease management. This study examined potential variables that correlate with inaccuracy of self-reported energy intake (EI) in adults with MS.

METHODS: Twenty-eight participants completed two assessment appointments within a 14-day period that included a standard doubly labeled water (DLW) protocol for estimating total energy expenditure (TEE). The participants reported their EI using the Automated Self-Administered 24 h (ASA24) Dietary Assessment Tool. The primary variables of interest for explaining the discrepancy between TEE and ASA24 EI (i.e., inaccuracy) included cognition (processing speed, visuospatial memory, and verbal …
