The objective was to examine associations between social jetlag and diet quality among young adults in the US using nationally representative data from the 2017-2018 NHANES survey, and evaluate effect modification by gender and race/ethnicity. Social jetlag was considered ≥2-hour difference in sleep midpoint (median of bedtime and wake time) between weekends and weekdays. Diet quality was assessed with the Healthy Eating Index (HEI)-2015 and its 13 dietary components.

Background And Objectives: Diet quality has improved over time for US adults and youth aged ≥2 years. Trends over time and disparities in the diet quality of toddlers 12 through 23 months old have not been documented. Our objective was to investigate the direction and magnitude of toddler diet quality trends from 1999 to 2018 overall and by household socioeconomic status.

Background: Ultraprocessed foods (UPFs) comprise >50% of United States adults' energy intake, with the proportion of calories from UPFs increasing over time and the proportion of unprocessed/minimally processed foods (MPFs) decreasing over time. Whether UPFs are primarily consumed at home (AH) or away from home (AFH) is important to inform policies and messages to improve dietary quality.

Objectives: We examined trends in consumption of UPFs and MPFs AH and AFH in a nationally representative sample of United States adults and within sociodemographic subgroups.

Article Synopsis
  • Chain restaurants in the US are promoting healthier and climate-conscious menu options, but research on their actual impact is limited.
  • A study analyzed menu data from 75 large chain restaurants between 2013-2021 to assess the availability and nutritional profiles of meat-based versus meat-free items.
  • While meat-free items generally had lower calories and better nutritional profiles, their availability hasn't significantly increased, indicating minimal progress in reducing climate impact.

In response to economic distress and food insecurity during the COVID-19 pandemic, Congress expanded the Supplemental Nutrition Assistance Program (SNAP) by introducing emergency allotments to increase monthly benefits, starting in March 2020. In March 2023, emergency allotments expired in the thirty-five states and territories still offering them. We provide some of the first evidence of the impacts of this loss of nutrition support-in some cases, more than $250 a month-for economically disadvantaged households.

Objectives: Growing research suggests that food insecurity is associated with worse cognitive functioning; however, prospective studies are needed to examine food insecurity and dementia risk. Using longitudinal and nationally representative data, we examined the effects of food insecurity on dementia risk among older adults.

Methods: Data were from 3,232 adults (≥65 years) from the Panel Study of Income Dynamics.

Quiescence is an important non-pathological state in which cells pause cell cycle progression temporarily, sometimes for decades, until they receive appropriate proliferative stimuli. Quiescent cells make up a significant proportion of the body, and maintaining genomic integrity during quiescence is crucial for tissue structure and function. While cells in quiescence are spared from DNA damage associated with DNA replication or mitosis, they are still exposed to various sources of endogenous DNA damage, including those induced by normal transcription and metabolism.

Background: Childhood food insecurity can persist among low socioeconomic areas in high-income countries. Universal Free School Meal (UFSM) programs are designed to respond to this pressing issue. This study aimed to conduct a multi-year evaluation of the DIATROFI Program's impact on household food insecurity in Greece.

Wheat, a component of the staple diet globally, is a common food allergen in children. The symptoms of wheat allergy (WA) range from skin rash to shortness of breath, significantly impairing quality of life. Following initial clinical suspicion, individuals may undergo routinely used allergy tests such as a wheat allergen-specific skin prick test (SPT), a blood test for specific immunoglobulin E (sIgE) levels, or oral food challenge.

Background: Food insecurity is a pivotal determinant of health outcomes. Little evidence exists on the association between food insecurity and health behaviors and outcomes, including diet quality, among graduate students or postdoctoral trainees.

Objectives: This study aimed to examine the association between food insecurity and diet quality among graduate students and postdoctoral trainees at 3 health-focused graduate schools (public health, medical, and dental medicine) within Harvard University.

Background: Effective interventions for metabolic liver disease include optimized nutritional intake. It is increasingly clear, however, that many patients with metabolic liver disease lack the resources to execute nutritional advice. Data on the trends of food insecurity are needed to prioritize public health strategies to address the burden of liver disease.

Article Synopsis
  • The study investigates how sexual identity, race, and ethnicity impact cardiovascular health disparities, highlighting a gap in existing research on these intersections.
  • Using data from the National Health and Nutrition Examination Survey, it analyzes cardiovascular health in noninstitutionalized, nonpregnant adults aged 18-59, focusing on self-reported sexual identity and race/ethnicity.
  • Results indicate that Black, Hispanic, and White sexual minority women have lower cardiovascular health scores compared to heterosexual women, after controlling for age, survey year, and socioeconomic factors.

Background: Food insecurity, a social and economic condition of limited availability of healthy food, is a risk factor for adverse cardiovascular health outcomes among adults; few studies have been conducted in adolescents. This study explores the association between food insecurity and cardiovascular health risk factors among a nationally representative sample of US adolescents, adopting the American Heart Association's Life's Essential 8 metric.

Methods And Results: We analyzed data from 2534 adolescents aged 12 to 19 years from the 2013 to 2018 National Health and Nutrition Examination Surveys.
