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.

A First Estimate of the Prevalence of Developmental Language Disorder in Mexico: A Retrospective Study.

This was a retrospective study that aimed to provide a first estimate of the prevalence of developmental language disorder (DLD) in Mexico, where there is currently a lack of epidemiological data on this disorder. Children aged 4;0 to 6;11 years in the cities of Mexico, Queretaro, and Monterrey were classified into two groups: those with DLD ( = 46) and those with typical language development ( = 497). The diagnosis of DLD was based on standardized norm-referenced assessment and language sample analyses.

Lifestyles of 2- to 11-year-old children during the COVID-19 pandemic.

Introduction: risk factors associated with obesity such as poor dietary quality, low physical activity (PA), screen time (ST), and poor sleep duration (SD) were affected during confinement resulting from the SARS-CoV-2 pandemic. Objective: the aim of our study was to evaluate the association between PA, ST and SD with the consumption of non-recommended food groups (N-RFG) in children during the COVID-19 pandemic, using data from ENSARS-CoV-2 Girls and Boys. Methods: data were gathered through a self-administered electronic survey carried out in four regions of Mexico during September and October 2020.

Overweight and obesity in women participating in social feeding programs in Mexico: data from vulnerable population groups in the Mexican National Nutrition and Health Survey 2018.

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).
