Mid- and long-term associations between food insecurity and sarcopenia.

Background: Sarcopenia is a complex geriatric syndrome characterized by progressive and generalized loss of skeletal muscle mass, muscle strength, and physical performance. Nutritional factors, including food insecurity, have been reported to be important in the development of sarcopenia. However, evidence on the relationship between sarcopenia and food insecurity is limited, especially with longitudinal data.

Next generation brain health: transforming global research and public health to promote prevention of dementia and reduce its risk in young adult populations.

Efforts to prevent dementia can benefit from precision interventions delivered to the right population at the right time; that is, when the potential to reduce risk is the highest. Young adults (aged 18-39 years) are a neglected population in dementia research and policy making despite being highly exposed to several known modifiable risk factors. The risk and protective factors that have the biggest effect on dementia outcomes in young adulthood, and how these associations differ across regions and groups, still remain unclear.

Capillary drops, capillary pooled, and venous blood samples for determining hemoglobin concentration using HemoCue: A measurement system analysis.

Several external and internal factors can affect the performance and variability of Hemoglobin concentration [Hb] measurements using HemoCue, and documentation on the contribution of different sources of [Hb] variation is limited. We used an experimental repeated measurements design with nine randomly selected participants, three HemoCue devices, and three trained field workers. HemoCue measurements for all samples were repeated three times.

Background: The study of dietary patterns in older adults (OA) and their association with geriatric syndromes (GS) is scarce in Latin America.

Objective: To describe the association of dietary patterns with GS in the Mexican older adult population, using data from the 2018-19 National Health and Nutrition Survey.

Methods: Dietary data were collected from 3,511 adults (≥60 years of age, both sexes) using a semi-quantitative food frequency questionnaire.

The Mediterranean diet is not associated with neuroimaging or cognition in middle-aged adults: a cross-sectional analysis of the PREVENT dementia programme.

Background And Purpose: The Mediterranean diet (MedDiet) has been associated with reduced dementia incidence in several studies. It is important to understand if diet is associated with brain health in midlife, when Alzheimer's disease and related dementias are known to begin.

Methods: This study used data from the PREVENT dementia programme.

Overview of Trends in Anemia and Iron Deficiency in the Mexican Population From 1999 to 2018-19.

Background: Despite the emergence of diverse programs in Mexico to address anemia and micronutrient deficiencies in disadvantaged groups, progress on reducing their prevalence has stagnated. In Mexico, anemia surveillance at the population level is conducted through the National Health and Nutrition Survey ENSANUT (for its acronym in Spanish).

Objective: To overview the trends in anemia and iron deficiency (ID) from 1999 to 2018-19 in the Mexican population before COVID-19 pandemic.

Prospective changes in anemia are associated with the incidence and persistence of sarcopenia among older Mexican adults.

Background: Low hemoglobin levels are a significant biomarker in the prognosis of sarcopenia. Anemia and sarcopenia are frequent and disabling conditions in the older adult population, but little is known about the role of anemia in the onset and progression of sarcopenia. This study aimed to determine whether prospective changes in anemia are associated with the incidence and persistence of sarcopenia.

Micronutrient Deficiencies in Older Adults in Latin America: A Narrative Review.

Background: The population in Latin America and Caribbean (LAC) has experienced a major demographic transition with increased numbers of older adults (OA). This change brings opportunities in the public health sector to implement health prevention interventions and delay the onset of geriatric syndromes. Micronutrients play an important role in the maintenance of biological function which contributes to longevity.

Hope for brain health: impacting the life course and society.

Hope is a cognitive process by which an individual can identify their personal goals and develop actionable steps to achieve results. It has the potential to positively impact people's lives by building resilience, and can be meaningfully experienced at both the individual and group level. Despite this significance, there are sizable gaps in our understanding of the neurobiology of hope.

Unveiling the Burden of Miscoding and Misclassification in Stroke Mortality: Analysis of Multiple Cause-of-Death Data in Mexico.

Background: The prevalence of risk factors for cerebrovascular diseases in Mexico is increasing although stroke mortality declined from 1990 to 2010, without meaningful changes afterward. While improving access to adequate prevention and care could explain this trend, miscoding and misclassification in death certificates need to be assessed to unveil the true burden of stroke in Mexico. Practices in death certification along with the presence of multi-morbidity could contribute to this distortion.

Anaemia in adolescent women: A priority for the nutrition agenda in Mexico. A comparison of data from the ENSANUT 2012 and 2018-2019 surveys.

The risk of anaemia in adolescence increases due to accelerated growth. This study aims to: (1) estimate the prevalence of anaemia in 2012 and 2018-2019 (Encuesta Nacional de Salud y Nutricion - ENSANUT [n = 5841 in 2012 and n = 2380 in 2018-2019]) in non-pregnant, Mexican adolescent women aged 12-19 years, and the changes in prevalence over this period according to sociodemographic, health and nutrition characteristics; (2) estimate the associations between anaemia and sociodemographic, health and nutrition characteristics in each year and overall, in non-pregnant Mexican adolescent women. Anaemia was defined as capillary haemoglobin <12 g/dL.

Trends in the burden of stroke in Mexico: A national and subnational analysis of the global burden of disease 1990-2019.

Background: Scarce epidemiological information on stroke in Mexico impedes evidence-based decisions and debilitates the design of effective prevention programmes at the local level.

Methods: Ecological and secondary analysis of Global Burden of Disease national and subnational data for Mexico, from 1990 to 2019. We analysed the incidence, prevalence, deaths, premature mortality, disability, and DALYs due to cerebrovascular disease included to identify the differences in the burden of stroke in Mexico by type of stroke (ischaemic [IS], intracerebral haemorrhage [ICH] and subarachnoid haemorrhage [SAH]), sex, age groups, and state levels ordered by quartiles of Sociodemographic Index (SDI).

Drops of Capillary Blood Are Not Appropriate for Hemoglobin Measurement with Point-of-Care Devices: A Comparative Study Using Drop Capillary, Pooled Capillary, and Venous Blood Samples.

Population-based surveys matched by time but using different methodologies for determining hemoglobin (Hb) concentration have shown inconsistencies in estimating anemia prevalence. This study aimed to estimate measurement errors in Hb quantification in HemoCue 201+ using venous blood (VB) and capillary blood both drops (DCB) and pools (PCB), and compare the results against those of a reference method (VB analyzed in hematology analyzers based on the cyanmethemoglobin method). Children ( = 49), adult females ( = 50), and older adults ( = 50) were randomly allocated to donate VB (4 mL) and either DCB (three drops) or PCB (350 µL).

Etiology of Anemia in Older Mexican Adults: The Role of Hepcidin, Vitamin A and Vitamin D.

Anemia in older adults is a growing public health issue in Mexico; however, its etiology remains largely unknown. Vitamin A deficiency (VAD) and vitamin D deficiency (VDD) have been implicated in the development of anemia, though by different mechanisms. The aim of this study is to analyze the etiology of anemia and anemia-related factors in older Mexican adults.
