Background: Food insecurity remains a global public health problem. Experiencing food insecurity is related to poorer cognitive function among older adults. However, few studies have examined how food insecurity, experienced over the life-course, relates to cognitive function among older adults in Mexico.
Methods: Data came from the 2015 Mexican Health and Aging Study ( = 11,507 adults aged 50 and over). Early- and late-life food insecurity were ascertained by self-report. We evaluated how both measures of food insecurity related to the performance of multiple cognitive tasks (Verbal Learning, Verbal Recall, Visual Scanning, and Verbal Fluency), while controlling for key health and sociodemographic confounders using linear regression.
Results: In descriptive analyses, respondents who experienced food insecurity in either early or late life performed significantly worse on all cognitive tasks when compared to the food secure. In models adjusted for health and sociodemographic confounders, early-life food insecurity predicted worse Verbal Learning performance and late-life food insecurity was associated with poorer Visual Scanning performance.
Conclusions: Food insecurity was related to poorer cognitive function in a nationally representative sample of older adults in Mexico. However, results suggested that the significance of effects depended on cognitive task and when in the life-course food insecurity was experienced.

Background: In Zambia, dementia prevalence is unknown due to limited community awareness and a lack of providers skilled in recognizing and diagnosing this disease. Community healthcare workers (CHWs) are widely utilized across sub-Saharan Africa to improve health care access, particularly HIV services. CHWs may be an untapped resource to raise awareness, screen for dementia, and support dementia care in the community.

Background: Food insecurity is associated with high morbidity and mortality and is typically measured with the 10-item US Adult Food Security Survey Module. Shorter instruments may capture similar information, but this has not been validated against mortality in general populations.
Methods: A nationally representative sample of individuals aged 20 to 74 years from the US National Health Interview Survey 2011 to 2018 was included, with deaths linked to the National Death Index through 2019.

Background: Persons aged 13-24 years are a priority population in the National HIV/AIDS Strategy. Young adults with HIV have poorer health outcomes-including not being retained in care, antiretroviral nonadherence, and not being virally suppressed-than other persons with HIV.
Setting: Centers for Disease Control and Prevention's Medical Monitoring Project data collected June 2018 through May 2022.

Task-shared psychological interventions are effective for reducing the severity of depression symptoms, but differences in treatment outcome by socioeconomic status is uncertain. This study examines socioeconomic inequalities (SEI) in depression outcomes among people with HIV and/or diabetes who participated in a cluster randomised controlled trial in the Western Cape Province of South Africa. The trial took place at 24 primary care clinics randomised to deliver a task-shared psychological intervention or treatment as usual (TAU).
