Objectives: The 50-59 age group in the United States experience higher levels of food insecurity (FI) compared to older adults. While previous research has identified an association between FI and cognition outcomes in older populations, limited research has examined midlife as a specific FI exposure window and the association of this hardship with long-run cognition outcomes.
Methods: Utilizing 14 waves of Health and Retirement Study (HRS) data (1995-2020), I applied mixed-effects models to assess the relationship between midlife FI exposure and later-life cognitive function, controlling for childhood disadvantages and other health-related and sociodemographic characteristics.
Results: Findings indicate that both cumulative FI duration and ever experiencing FI during ages 50-59 are significantly associated with subsequent cognitive decline. Specifically, ever experiencing FI during midlife was linked to a decrease in cognitive function by 0.07 standard units (95% confidence interval [CI], -0.13 to -0.003; p < .05). In addition, each additional year of FI exposure during midlife was associated with a reduction in cognitive function by 0.01 standard units (95% CI: -0.03 to -0.003; p < .05). These associations remained robust even after accounting for a range of potential confounders and covariates.
Discussion: The findings support the cumulative inequality model, suggesting that midlife FI is a significant predictor of lower cognitive function in later life. Both the timing and extent of FI during midlife are crucial factors in shaping cognitive health outcomes. Policy interventions targeting FI in the 50-59 age group could play a pivotal role in promoting healthy aging and mitigating cognitive decline in older adulthood.

Background: Food insecurity is associated with poor health outcomes; however, the connection with cancer care is not well understood. This study aimed to evaluate the impact of county-level food insecurity on the surgical management and survival of patients with esophageal cancer.
Methods: Patients with stage I to III esophageal cancer were identified from Surveillance Epidemiology and End Results data (2010-2016).

Objective: Explore the relationship between water insecurity and food security and their covariates in Mexican households.
Design: A cross-sectional study with nationally representative data from the National Health and Nutrition Survey-Continuous 2021 (in Spanish, ENSANUT-Continua 2021), collected data from 12,619 households.
Setting: Water insecurity was measured using the Household Water Insecurity Experiences (HWISE) Scale in Spanish and adapted to the Mexican context.
Understanding the Medical Education Experiences of Low-Income Students Through a Maslow's Hierarchy of Needs Lens: An Exploratory Qualitative Study.
J Gen Intern Med

MD/PhD Program, Yale School of Medicine, New Haven, CT, USA.
Background: Diversity in the physician workforce is critical for quality patient care. Students from low-income backgrounds represent an increasing proportion of medical school matriculants, yet little research has addressed their medical school experiences.
Objective: To explore the medical school experiences of students from low-income backgrounds using a modified version of Maslow's Hierarchy of Needs (physiologic, safety, love/belonging, esteem, and self-actualization) as a theoretical framework.
Drivers of stunting and wasting across serial cross-sectional household surveys of children under 2 years of age in Pakistan: potential contribution of ecological factors.

Background: The impact of direct and indirect drivers on linear growth and wasting in young children is of public health interest. While the contributions of poverty, maternal education, empowerment and birth weight to early childhood growth are well recognized, the contribution of environmental factors like heat, precipitation, agriculture outputs and food security in comparable datasets is less well established.
Objectives: To investigate the association of length-for-age z-score (LAZ) and weight-for-length z-score (WLZ) with various indicators among children under 2 years of age in Pakistan using representative household level nutrition surveys and ecological datasets.
