Context: Meal skipping may contribute to nutrient deficiency across the lifespan. Multiple socioecological factors have been identified as correlates of meal skipping in adolescents and adults, but evidence in older adults is limited.
Objective: To determine the socioecological correlates of meal skipping in community-dwelling older adults.
Data Source: Embase, PsycINFO, CINAHL, and MEDLINE electronic databases were systematically searched from inception to March 2021.
Data Extraction: A total of 473 original research studies on socioecological factors and meal skipping among community-dwelling adults aged ≥65 years were identified. Title, abstract, and full-text review was performed by 2 reviewers independently, and a third reviewer resolved disagreements. A total of 23 studies met our inclusion criteria. Data were extracted by 1 reviewer from these studies and independently verified by another. The Newcastle-Ottawa Scale was used to assess methodological quality.
Data Analysis: The frequency of meal skipping in included studies ranged between 2.1% and 61%. This review identified 5 domains of socioecological correlates associated with meal skipping in older adults: sociodemographic, behavioral, biomedical, psychological, and social.
Conclusion: Understanding the factors associated with meal skipping in older adults can inform the development of targeted interventions to improve nutrition and health.
Systematic Review Registration: PROSPERO registration no. CRD42021249338.

Department of Geriatric Medicine, Xuanwu Hospital, Capital Medical University, China National Clinical Research Center for Geriatric Medicine, Beijing 100053, China.
Objective: Effective methods for establishing an aged animal model of diabetes and glycemic fluctuation have rarely been investigated. The aim of the study was to explore the feasibility of inducing glycemic fluctuation in aged Sprague-Dawley rats and to evaluate the corresponding changes in cognitive function.
Methods: Male rats aged 48 weeks were fed a high-fat and high-glucose diet and given streptozotocin intraperitoneally to establish a rat model of type 2 diabetes mellitus (T2DM).

Background And Aims: Obesity represents a crucial modifiable risk factor for cardiovascular complications. Two dietary approaches, Very Low-Calorie Ketogenic (VLCKD) and Intermittent Fasting (IFD) diets, have demonstrated to reduce blood pressure (BP) and produce cardiovascular and metabolic advantages. We aimed to evaluate the effects of VLCKD or IFD compared to Free Diet (FD) on office brachial and central systolic BP levels.

Ramadan intermittent fasting can pose challenges and risks for some groups of patients. Based on a narrative literature review and our clinical expertise, we provide practical guidance for clinicians managing patients with gastrointestinal and hepatobiliary conditions who wish to fast during Ramadan. Following the established International Diabetes Federation and Diabetes and Ramadan International Alliance risk stratification framework, we categorised patients' risk as low or moderate, high, or very high.

Objective: Identify the most important sociodemographic and behavioral factors related to the diet of low-income adults with hypertension in order to guide the development of a community health worker (CHW) healthy eating intervention for low-income populations with hypertension.
Design: In this cross-sectional analysis, dietary recalls were used to assess Healthy Eating Index-2020 (HEI-2020) total (range: 0 to 100 [best diet quality]) and component scores and sodium intake. Self-reported sociodemographic and behavioral data were entered into a Least Absolute Shrinkage and Selection Operator (LASSO) regression model to determine the relative importance of factors related to diet quality.
