OBJECTIVE Prediabetes in young people is an emerging epidemic that disproportionately impacts Hispanic populations. We aimed to develop a metabolite-based prediction model for prediabetes in young people with overweight/obesity at risk for type 2 diabetes. RESEARCH DESIGN AND METHODS In independent, prospective cohorts of Hispanic youth (discovery; n = 143 without baseline prediabetes) and predominately Hispanic young adults (validation; n = 56 without baseline prediabetes), we assessed prediabetes via 2-h oral glucose tolerance tests. Baseline metabolite levels were measured in plasma from a 2-h postglucose challenge. In the discovery cohort, least absolute shrinkage and selection operator regression with a stability selection procedure was used to identify robust predictive metabolites for prediabetes. Predictive performance was evaluated in the discovery …

Although pediatric growth curves provide clinical utility, using these metrics for within‐person change over time can be misleading. As research is focused on understanding cardiometabolic consequences of weight gain, it is important to use precise metrics to analyze these longitudinal research questions. Despite several foundational recommendations to limit the use of reference pediatric growth curves (e.g., BMI z scores) for within‐person longitudinal research, it has evolved into the “gold standard” for using growth curves for pediatric weight gain analyses. Therefore, the objective of this paper is to discuss (A) the methodology used to create reference growth curves; (B) the appropriate use of reference pediatric BMI growth curves within the context of cross‐sectional and longitudinal analyses in research; and (C) how to select metrics based on desired evaluations. Careful consideration using standardized …

Introduction Shift work disorder (SWD) is a circadian rhythm sleep disorder associated with increased chance of experiencing poor mental health symptoms and physical health complaints. Traditional protective factors, such as resilience, as well as the ability to sleep at different times of the day, known as sleep flexibility, are known to reduce the risk of SWD, and to protect against poor mental health. However, more research is needed to understand how protective factors and SWD risk interact to predict health and wellbeing outcomes. The current study aimed to explore the role of traditional and sleep-specific protective factors in buffering the impact of high SWD risk on mental health and physical health complaints. Methods One hundred and twenty-six permanent nightshift workers or those working rotating shift schedules including nightshifts participated in an online cross …

The assessment of “omics” signatures may contribute to personalized medicine and precision nutrition. However, the existing literature is still limited in the homogeneity of participants’ characteristics and in limited assessments of integrated omics layers. Our objective was to use post-prandial metabolomics and fasting proteomics to identify biological pathways and functions associated with diet quality in a population of primarily Hispanic young adults. We conducted protein and metabolite-wide association studies and functional pathway analyses to assess the relationships between a priori diet indices, Healthy Eating Index-2015 (HEI) and Dietary Approaches to Stop Hypertension (DASH) diets, and proteins (n = 346) and untargeted metabolites (n = 23,173), using data from the MetaAIR study (n = 154, 61% Hispanic). Analyses were performed for each diet quality index separately, adjusting for demographics and BMI. Five proteins (ACY1, ADH4, AGXT, GSTA1, F7) and six metabolites (undecylenic acid, betaine, hyodeoxycholic acid, stearidonic acid, iprovalicarb, pyracarbolid) were associated with both diets (p < 0.05), though none were significant after adjustment for multiple comparisons. Overlapping proteins are involved in lipid and amino acid metabolism and in hemostasis, while overlapping metabolites include amino acid derivatives, bile acids, fatty acids, and pesticides. Enriched biological pathways were involved in macronutrient metabolism, immune function, and oxidative stress. These findings in young Hispanic adults contribute to efforts to develop precision nutrition and medicine for diverse populations.

Human milk oligosaccharides (HMOs) impact neonate immunity and health outcomes. However, the environmental factors influencing HMO composition remain understudied. This study examined the associations between ambient air pollutant (AAP) exposure and HMOs at 1-month postpartum. Human milk samples were collected at 1-month postpartum (n = 185). AAP (PM2.5, PM10, NO2) exposure included the 9-month pregnancy period through 1-month postpartum. Associations between AAP with (1) HMO diversity, (2) the sum of sialylated and fucosylated HMOs, (3) 6 a priori HMOs linked with infant health, and (4) all HMOs were examined using multivariable linear regression and principal component analysis (PCA).

Methods: MetaAir study participants (n= 154, 61% Hispanic) completed a clinical visit between 2014-2018. The Healthy Eating Index-2015, Dietary Approaches to Stop Hypertension, and Mediterranean diet scores were calculated from two 24-hour dietary recalls. Targeted proteomics (346 proteins) were measured in a cardiometabolic panel and untargeted metabolomics were assessed using LC-HRMS. The results of metabolite-and protein-wide association studies were used in functional pathway analysis with MetaboAnalyst and Reactome, respectively. Analyses were performed for each diet index separately, adjusting for demographics and BMI.Results: 16.4% of metabolite and 20% of protein features were significantly (p< 0.05) associated with at least one diet index. Two annotated metabolites (L-methionine, prostaglandin F2α) and four proteins (ACY1, ADH4, AGXT, GSTA1) were associated with all three dietary indices. These features are involved in amino acid metabolism, liver function, and inflammation, and are involved in biological pathways like arachidonic acid metabolism, prostaglandin formation, and biological oxidations. Overall, 21 metabolomics and 84 proteomics pathways were associated with at least one diet index and had similar functions, including those related to cell signaling and growth, hemostasis, immune function, and hormone regulation.Discussion: Adherence to healthy dietary patterns influences biological pathways involved in disease development and progression. Omics analyses may provide information about the mechanisms by which a healthy diet improves human health.

Breast milk contains thousands of bioactive compounds including extracellular vesicle microRNAs (EV-miRNAs), which may regulate pathways such as infant immune system development and metabolism. We examined the associations between the expression of EV-miRNAs and laboratory variables (i.e., batch effects, sample characteristics), sequencing quality indicators, and maternal-infant characteristics. The study included 109 Latino mother-infant dyads from the Southern California Mother’s Milk Study. Mothers were age 28.0 ± 5.6 and 23-46 days postpartum. We used principal components analysis to evaluate whether EV-miRNA expression was associated with factors of interest. Then, we used linear models to estimate relationships between these factors and specific EV-miRNA counts and analyzed functional pathways associated with those EV-miRNAs. Finally, we explored which maternal-infant characteristics predicted sequencing quality indicators. Sequencing quality indicators, predominant breastfeeding, and breastfeedings/day were associated with EV-miRNA principal components. Maternal body mass index and breast milk collection timing predicted proportion of unmapped reads. Expression of 2 EV-miRNAs were associated with days postpartum, 23 EV-miRNAs were associated with breast milk collection time, 23 EV-miRNAs were associated with predominant breastfeeding, and 38 EV-miRNAs were associated with breastfeedings/day. These EV-miRNAs were associated with pathways including Hippo signaling pathway and ECM-receptor interaction, among others. This study identifies several important factors that may …
