Background: Stroke continues to be a major cause of morbidity mortality in the United States. In this study, we determined if the food insecurity status interacted with a history of stroke to influence the overall mortality risk. Methods: Data from the 2015–2018 National Health and Nutrition Examination Survey, a nationally representative survey among the non-institutionalized population that is published in two-year cycles, with a mortality follow-up through 31 December 2019 was analyzed in this investigation. Results: In stroke survivors, upon follow-up, a higher proportion of those with food insecurity died (38.1% vs. 31.6%, p < 0.05) than food-secure individuals. For overall mortality, the crude hazard ratio (HR) for stroke survivors was 5.87 (95% confidence interval [CI], 3.18–10.86, p < 0.01). After adjustment for multiple variables, the HR was significantly elevated, 3.66 (CI 1.64–8.14, p < 0.01), among stroke survivors with food insecurity, but among those with stroke only or just food insecurity, the HR was not significantly elevated. Similar interactions were seen among females but not among males. Conclusions: Food insecurity substantially increases mortality from all causes among stroke survivors. When considering various chronic diseases, such as stroke, the role of social problems must be taken into consideration. Full article

Real-time health assessment is crucial for diagnosing emerging threats to wildlife. Point-of-care instruments now allow detailed, affordable measurements of blood metabolites (e.g., glucose, triglycerides, ketones) in free-ranging animals. Ketones, however, remain understudied, especially in relation to environmental and life-history traits. Here, we assessed blood ketone variation in male House Finches (Haemorhous mexicanus) across two seasons (summer and winter) as a function of body condition, circulating glucose, carotenoids, lipid-soluble vitamins, and habitat urbanization (urban/suburban/rural). In both seasons, the interaction between capture site and glucose concentration predicted ketone levels: urban and suburban birds showed a negative relationship, while in summer, rural birds showed a positive one. Additionally, in winter, ketone levels were negatively associated with plasma carotenoids, indicating birds with higher carotenoid levels had lower ketone concentrations. These findings suggest that similar to patterns seen in biomedical research and our previous work on carotenoids and health, ketone status can serve as a valuable indicator of nutritional condition and fat metabolism in wild birds, particularly in the context of urbanization.

Background: Preconception diet and nutritional status are important determinants of reproductive and pregnancy health. As a comprehensive evaluation, this paper describes harmonization of diet data across multiple cohorts including over 50,000 participants and the differences between them. This information may be useful for developing targeted strategies to improve women’s diet prior to pregnancy for optimal prenatal health outcomes. Methods: The Preconception Period Analysis of Risks and Exposures influencing health and Development (PrePARED) consortium incorporates studies covering the preconception period and includes both couples planning pregnancy and studies covering the reproductive period but not focused on pregnancy. We harmonized data on 56,520 participants from seven cohort studies that collected data during the preconception period. We generated data on diet quality according to the International Federation of Gynecology and Obstetrics (FIGO) nutrition checklist to examine diet quality measures across the cohorts and compare estimates of diet quality across studies. Four studies used food frequency questionnaires; one used a study-specific diet history; one used two 24 h dietary recalls; and one used a short series of general diet questions. Positive responses on the six FIGO questions were tallied to calculate a total diet quality score. Results: Cohort samples varied in terms of age; socioeconomic status; race; ethnicity; and geographic region. Across the cohorts, participants met a median of three or four of the FIGO criteria for diet quality; those most commonly met were recommendations for consumption of meat and protein, while those least commonly met were recommendations for limiting consumption of processed foods and snacks. There was greater variation in meeting recommendations for the consumption of fruits and vegetables; dairy; fish; and whole grains. The percentage meeting ≤ 2 criteria ranged from 6.4% (Coronary Artery Risk Development in Young Adults) to 40.4% (Bogalusa Heart Study). Discussion: There was wide variability across preconception cohort studies in the extent to which participants met FIGO dietary guidelines. Although studies were conducted in populations that were not likely to be malnourished, it was rare for women to meet all the preconception dietary recommendations. These findings illustrate a need for strategies to promote meeting dietary guidelines prior to conception to improve health outcomes. Full article

Background/Objectives: In the last decade, there has been a notable increase in the prevalence of cognitive decline among the elderly population. This phenomenon is further compounded by the concurrent rise in life expectancy, indicating a growing concern for the health and well-being of individuals in this demographic. Dementia has become a disease with a strong social impact, not exclusively limited to its health dimension. It is generally accepted that lifestyle factors and psychological attitudes toward life challenges may serve as protective mechanisms against pathological cognitive decline. The objective of this contribution is to evaluate the impact of lifestyle factors (e.g., physical activity, employment history, nutrition, technology use, etc.), stressors (e.g., illness, rare events, abandonments, home moving, etc.), and sociability (e.g., marriage, active friend network, children proximity, work relationships, etc.) at the onset of pathological cognitive frailty. Methods: In this study, a semi-structured interview was administered to 32 individuals over the age of 65 during their initial neuropsychological evaluation for suspected dementia. Results: Linear regressions with Mini Mental State Examination scores indicated that lifestyle and sociability factors offer a degree of protection against cognitive decline, while stressors were found to be unrelated to this phenomenon. Conclusions: The utilization of contemporary technologies, the possession of a driver’s license, and the maintenance of an active social network have been demonstrated to possess a high degree of predictive value with respect to cognitive reserve in the context of aging.

: Depression, commonly known as unipolar affective disorder, is one of the most prevalent mental illnesses in contemporary society, affecting individuals to varying degrees. Tea is one of the three major non-alcoholic beverages globally; it has a rich history of consumption and is associated with numerous health and nutritional benefits. This review systematically summarizes the antidepressant effects of various bioactive compounds found in tea, drawing upon research findings in the field of tea’s functional health. It elucidates the impact of tea’s bioactive components on the hypothalamic–pituitary–adrenal (HPA) axis, the nervous system, the immune system, intestinal microflora, and the monoaminergic system, among other physiological sites, to achieve antidepressant effects. These effects primarily involve enhancing neural signaling pathways, regulating neural signaling molecule levels, and reducing neuroinflammation. Tea may normalize the body’s nervous system by bolstering immune function, alleviating or eliminating cellular inflammation to maintain healthy homeostasis, or improving intestinal flora and mitigating stress to prevent or treat depressive disorders. Additionally, the potential social support derived from tea-drinking activities, such as cultural rituals and interpersonal communication, may contribute to its antidepressant effects. This review discusses and analyzes the current research status regarding the antidepressant effects of tea and highlights that tea and its active ingredients can be utilized to prevent and alleviate depression.

Objectives: Dietary conditions are closely related to maternal health. This study aims to investigate the causal relationship between the first–second-trimester Dietary Inflammatory Index (DII) and developing anemia in the third trimester. Methods: This prospective cohort study comprised 545 pregnant women, with dietary data assessed via a semi-quantitative food frequency questionnaire (FFQ). Hemoglobin levels were obtained by hospital laboratory tests and used to diagnose anemia. Multivariable logistic regression models—adjusted for baseline serum iron, age, pre-pregnancy body mass index (BMI), occupation, education, history of adverse pregnancy outcomes, parity, serum iron, passive smoking exposure, and iron supplementation use during pregnancy—were employed to evaluate the relationships between the first-trimester DII, second-trimester DII, first–second-trimester average DII, and third-trimester anemia. Results: After multivariable adjustment, the first–second-trimester average DII in the pro-inflammatory diet group demonstrated a 3.73-fold elevated risk of third-trimester anemia compared to the anti-inflammatory diet group (Odds Ratio [OR] = 3.73, 95% Confidence Interval [CI]: 1.50–9.25). Conclusions: Pro-inflammatory dietary patterns during pregnancy exhibit a significant correlation with developing third-trimester anemia. This study demonstrates that reducing dietary pro-inflammatory components through prenatal nutrition programs may lower third-trimester anemia risk. Notably, this study carries potential risks of bias, including self-reporting bias in dietary data and incompletely controlled confounding factors (such as unmeasured biomarkers). Full article

Olive oil (OO) has longstanding significance in human history, particularly in the Mediterranean region, where it has been a cornerstone of diet, economy, and culture. This history adds to modern evidence-based knowledge. Background: The Mediterranean diet (MD), rich in plant-based foods and OO, has been extensively associated with improved cardiometabolic and cognitive health. Recent interest has emerged in understanding how intermittent fasting protocols may enhance these effects. Still, the quality of OO does not only lie in the extraction process; it is also dependent on the tree variety, the soil, and the agricultural practices, ending with the way in which the finished product is stored and consumed. Objectives: This review explores the synergistic potential between OO consumption and intermittent fasting, focusing on their combined impact on metabolic health, oxidative stress, and inflammatory pathways. Methods: A literature search was conducted using multiple databases to identify studies addressing the health effects of OO, fasting, and the MD. Both human and relevant preclinical studies were considered, with emphasis on those evaluating inflammatory markers, lipid metabolism, insulin sensitivity, and neuroprotective mechanisms. Results: Evidence suggests that the bioactive compounds in EVOO may potentiate the benefits of fasting by enhancing antioxidant capacity, reducing postprandial inflammation, and modulating gene expression related to cellular metabolism. Combined, these factors may support improved insulin sensitivity, reduced oxidative damage, and delayed onset of age-related diseases. Conclusions: Understanding the integrative role of OO and fasting within the MD framework could offer valuable insights for nutritional strategies aimed at preventing metabolic syndrome, type 2 diabetes, and neurodegeneration. These findings also support the need for future clinical trials exploring the timing, dosage, and dietary context in which these interventions are most effective. Full article

Suicide is a major public health problem that has grown at alarming rates in the last two decades. Colorectal cancer (CRC) is one of the most common causes of cancer deaths in the United States in both males and females. However, the influence of suicidal ideation (SI) on the association between CRC and risk of mortality has not been well examined. Methods: For this study, the 2005–2018 National Health and Nutrition Examination Survey (NHANES), a nationally representative survey of United States adults aged 20 years or older, was utilized. CRC survivorship was determined from self-reported data on CRC, and mortality was ascertained by linking the NHANES data with death files from the National Death Index up to December 2019. Suicidal ideation (SI) confirmation was based on a response to a survey question. Results: People with SI had a significantly higher rate (12.3% vs. 7.5%, p < 0.01) of mortality than those without SI. Also, individuals with CRC (2.4%) had a statistically significant higher rate of frequent SI (almost daily) than individuals without CRC (0.6%). Upon a mean follow-up of 7.5 years, more CRC survivors (34.6%) died than non-CRC survivors (7.6%). The adjusted HR was elevated HR = 5.4 among individuals who had CRC and SI but close to 1.0 among individuals who had a history of CRC alone after adjusting for demographic and health variables. Conclusions: In this first national study in the U.S., we found that SI and CRC combined had worse mortality outcomes than CRC alone. Additionally, people with CRC were more likely to experience frequent SI. Our findings underscore the importance of mental healthcare and psychological well-being promotion among individuals with chronic diseases and the high need for integrated care approaches that address both physical and mental health needs.

Background: Assessing nutrition-related health risks in older individuals is often overlooked in clinical practice due to the lack of appropriate methods of evaluation. While anthropometric measurements and body composition analyses are mainly used, these tools are not standardized for the oldest old and fail to account for age-related changes. This underscores the need for improved assessment techniques that accurately capture the progressive and non-linear shifts in nutritional status throughout the aging process. Accordingly, the primary aim of our paper is to identify the most effective tools to use for evaluating nutritional status in the oldest population. Methods: To address this gap, we conducted a cross-sectional study, investigating the nutritional status of a cohort of Sicilian individuals aged between 65 and 111, using methods commonly applied to adult and older adult populations. These included the BIoimpedance Analysis (BIA), the Mini Nutritional Assessment (MNA) evaluation, and nutritional risk indices such as the COntrolling NUTritional Status (CONUT) score and Geriatric Nutritional Risk Index (GNRI). Results: Despite the oldest population being classified as “at risk” of malnutrition by the MNA or “cachetic” by BIA, our results indicated a “normal” or “low risk” of malnutrition when assessments were performed using tools (GNRI and CONUT) that were not reliant on body composition parameters. These findings align with clinical history assessments conducted during their recruitment. Conclusions: This pilot study highlights the need for future research aimed at developing standardized, multidimensional assessment models tailored to the heterogeneity of each age group, to improve risk stratification, clinical outcomes, and personalized nutritional care.

Background: The growth patterns of children and adolescents are influenced by multiple factors. This study employed structural equation modeling (SEM) to determine the primary factors influencing the growth of Palestinian children and adolescents in the West Bank (WB). Methods: A cross-sectional survey conducted in 2022 in the WB collected data from 1400 households, of which 500 with children aged 5–17 years and were selected for analysis. The survey assessed household food insecurity, socioeconomic status (SES), parental health history, nutritional awareness, food consumption patterns, and nutrient intake. The latent construct “Child Growth” was measured using Body Mass Index-for-age Z-score (BAZ), height-for-age Z-score (HAZ), and Mean Adequacy Ratio (MAR). SEM was employed to examine the interrelations among latent variables and their observed indicators. Results: Mineral intake showed the strongest direct effect on child growth (β = 0.812, p < 0.001), followed by food availability (β = 0.492), vitamin intake (β = 0.481), SES (β = 0.439), and macronutrient intake (β = 0.383). MAR exhibited the highest factor loading as a growth indicator, while HAZ had limited significance, suggesting its chronic nature. SES influenced growth both directly and indirectly through its effects on food availability and dietary intake pathways. Strong correlations between nutritional knowledge and nutrient classes reflect the interrelationship between behavioral and biological determinants. Conclusions: Both structural and immediate nutritional factors influence child growth. In Palestinian youth, mineral intake, food security, and SES have the greatest influence. These findings offer a framework for understanding the growth determinants of Palestinian youth in the WB and support the development of targeted interventions to improve dietary quality and overall nutritional status.

Background/Objectives: The consumption of highly processed foods (HPFs) is increasing on a global scale, and these foods have been associated with non-communicable diseases (NCDs). In particular, the consumption of HPFs has been associated with the intensification of inflammatory responses, with these foods being implicated in the exacerbation of chronic inflammatory conditions. Conversely, ultra-processed foods (UPFs) have been indicated as a possible factor in the pathogenesis of inflammatory bowel disease (IBD), particularly Crohn’s disease (CD). Methods: From October 2023 to October 2024, 275 patients with IBD were screened at a tertiary referral center. This study’s control cohort comprises 101 individuals from the local population. All study participants answered a questionnaire asking about the participants’ sex, body type and weight, height, age, marital status, employment, and other sociodemographic information. All subjects had to complete a food frequency questionnaire (FFQ) and the German version of the Screening Questionnaire of Highly Processed Food Consumption (sQ-HPF). IBD patients answered questions about their disease course and history as well as objective parameters of inflammation have been collected. Results: The sQ-HPF (%) showed significant differences (p < 0.001; g = −0.5) between the IBD cohort and the control group, suggesting higher HPF consumption within the IBD cohort. A subsequent analysis of the IBD cohort found no significant difference by disease type (Crohn’s disease: p = 0.441; g = −0.1; ulcerative colitis: p = 0.170; g = −0.3) or sex (women: p = 0.219; g = 0.2; men: p = 0.522; g = 0.1), but men with colitis did show higher HPF% compared to women with the same diagnosis. Spearman’s rho revealed no significant correlation between fecal calprotectin and HPF% in men with CD (p = 0.155, r = 0.191) or women with CD (p = 0.836, r = 0.026), and no correlation in men with UC (p = 0.707, r = 0.057) or women with UC (p = 0.560, r = −0.099). IBD health-related quality of life showed a significant positive correlation with HPF consumption in CD men (p = 0.026, r = 0.278), but not in CD women (p = 0.539, r = 0.075). No significant correlations between HPF consumption and health-related quality of life have been found in UC (men: p = 0.663, r = −0.064; women: p = 0.445, r = 0.121). Conclusions: The German version of the sQ-HPF is a reliable tool for rapid screening of habitual HPF% consumption in IBD patients. The findings of this analysis indicate a clear deviation from the recommended nutritional regimens for IBD, emphasizing the imperative for further investigation and the potential development of interventions to address these dietary discrepancies, with the ultimate goal of optimizing health outcomes for these patients.

Background/Objectives: This study aims to determine the prevalence of stunting in children under two years old and its association with the maternal profile (including anthropometric measurements), care, feeding practices, and socioeconomic level. It also attempts to assess if stunting may contribute to an underestimation of wasting by performing a preliminary speculative analysis using the expected height for age instead of the real observed height of the children. Methods: The study employed a cross-sectional design, examining mother–child pairs in the rural municipality of Ampefy in the Itasy Region of Madagascar, between 2022 and 2023. A total of 437 mother–child (0–24 months) pairs participated in the study. A questionnaire was administered to collect data on the maternal lifestyle. Maternal medical histories were reviewed, and anthropometric parameters of both the mothers and their child were taken by specialized and trained health professionals with multiple years of experience. Results: The prevalence of stunting in children was 57.4% (95% CI: 52.64–62.10). Stunting was associated with maternal anthropometric measurements (p < 0.001), maternal education (p = 0.004), and breastfeeding (p = 0.047), which appears to have a protective effect. The weight-for-length z-score indicated that only 12.4% of the total children were affected by wasting. In the preliminary speculative analysis using the WHO height-for-age standard, the theoretical prevalence of wasting was estimated to be 42.3%, with a considerable prevalence of severe wasting. The main limitations of this study were the possible selection bias, the limitations inherent to the taking of anthropometric measurements in small children, and therefore, the possible misclassification of the children. The use of a theoretical weight-for-length z-score to estimate a theoretical prevalence of wasting using an untested speculative analysis is also a limitation to the validity of the estimation. Conclusions: Stunting affected over half of the children included in the study (57.4%), but the prevalence of wasting was below what was expected, at 12.4%. In the preliminary speculative analysis using the expected height for age, it was estimated that wasting could possibly affect up to 42.3% of the children. This discrepancy, while it cannot be taken as factual due to the nature of the analysis, could serve as a warning that perhaps the elevated rates of stunting may be masking wasting in some children and other forms of nutritional assessments may be needed in areas where stunting is prevalent.

Background/Objectives: Possible sarcopenia and malnutrition are critical public health concerns among older adults, particularly in vulnerable populations such as those with a history of homelessness. However, limited evidence exists on the nutritional status and muscle health of this group in Thailand. Methods: This study aimed to assess the nutritional status of formerly homeless older adults residing in supportive housing in Thailand and examine its association with possible sarcopenia. A cross-sectional study was conducted among 116 participants aged 50 years and older. Sociodemographic information was collected using a structured questionnaire. Nutritional status was then assessed using the Mini Nutritional Assessment short form (MNA-SF) and body mass index (BMI). Possible sarcopenia was determined based on the Asian Working Group for Sarcopenia (AWGS) 2019 criteria, including low calf circumference, reduced handgrip strength, and/or low gait speed. Data were analyzed using descriptive statistics and logistic regression. Results: Of all participants, 66.4% were male, with a mean age of 59.14 years (SD = 7.791). A total of 78.4% were identified as having possible sarcopenia. Univariate analysis revealed significant associations between possible sarcopenia and malnutrition (OR = 6.111, 95% CI = 2.104–17.750), low BMI (OR = 16.784, 95% CI = 3.729–75.535), and waist circumference (OR = 0.129, 95% CI = 0.049–0.342). Multivariate logistic regression indicated that malnutrition (OR = 3.429, 95% CI = 1.093–10.763) and low BMI (OR = 11.732, 95% CI = 2.523–54.567) were significant predictors of possible sarcopenia, collectively explaining 33.8% of the variance. Conclusions: The findings underscore a high prevalence of possible sarcopenia among formerly homeless older adults in supportive housing in Thailand and highlight poor nutritional status, particularly low BMI and malnutrition, as a key contributing factor. These results emphasize the importance of early nutritional screening and interventions to prevent or delay sarcopenia in this vulnerable population. Full article

Background/Objectives: Sarcopenia and frailty are interrelated conditions and have a high incidence in older adults. They contribute to increased morbidity and mortality and poor quality of life. There is emerging evidence that healthy diets such as the Mediterranean diet could delay the onset of sarcopenia and frailty. This review aims to evaluate the role of the MD in preventing these conditions. Methods: A literature search was conducted on PubMed (MEDLINE, NCBI) for English-language articles published within the last 10 years (2014–2024) using the search terms “Mediterranean diet”, “frailty”, “sarcopenia”, and “old people”. A total of 111 articles were identified, of which 36 were excluded during the initial screening. Subsequently, 75 manuscripts were assessed for eligibility. Subsequently, a further 62 articles were excluded (narrative reviews, articles not focused on the elderly population, or articles with different outcomes). Finally, 13 articles were included in the review. Results: The 13 selected studies comprised seven observational studies, three systematic reviews and meta-analyses, and three clinical trials. The findings suggest that adherence to the Mediterranean diet (MD), particularly when combined with physical activity, may improve body composition and cardiometabolic health and reduce indicators of sarcopenia in obese older adults. Furthermore, MD-based nutritional interventions were associated with improved physical functions such as balance, gait, fall risk, flexibility, and muscle strength (p < 0.05, all). The MD also demonstrated a preventive effect against frailty, particularly in pre-frail individuals. Conclusions: High adherence to the Mediterranean diet (MD) may delay the onset of sarcopenia and improve muscle function in older adults. However, the available scientific evidence is of low to moderate quality. Well-designed prospective intervention studies are needed to confirm whether the MD can modify the natural history of sarcopenia and/or frailty in older adults. Full article

Background: The aim of this study was to assess the relationship between sleep-related variables (sleep duration, sleep trouble, and sleep disorder), comprehensive sleep patterns, and the reported history of cataract surgery in the U.S. population aged 20 years and older. Methods: We utilized data from the National Health and Nutrition Examination Survey (NHANES) 2005–2008 database. First, we analyzed the association between covariates and the reported history of cataract surgery using univariable Poisson regression. Subsequently, we constructed three models to evaluate the association between sleep-related variables and the reported history of cataract surgery using multivariable Poisson regression. Subgroup analyses were conducted to determine whether the association between sleep and the reported history of cataract surgery exhibited heterogeneity. Finally, we performed a sensitivity analysis to assess the stability of the results. Results: A total of 8591 participants were included in this study, among whom 774 had a history of cataract surgery. After adjusting for all covariates, participants experiencing sleep trouble had a higher prevalence of reported history of cataract surgery than participants without sleep trouble [PR = 1.40; 95%CI = (1.22, 1.62)]. Regarding combined sleep, participants with poor sleep patterns had a 36% higher prevalence of reported history of cataract surgery than those with healthy sleep patterns [PR = 1.36; 95%CI = (1.13, 1.64)]. The results of the sensitivity analysis indicate that the relationship between sleep patterns and the reported history of cataract surgery is robust. Conclusions: Sleep trouble and poor sleep patterns are positively linked to the high prevalence of a reported history of cataract surgery. Further research is needed to explore the underlying mechanisms. Full article
