Height growth of Mexican boys by geographic region: an evaluation based on nationally representative data of ENSANUT 2012 and 2018.

Existing research on human growth in Mexico is regionally focused, creating a gap in the understanding of growth patterns of children and adolescents at national level and regional variation. The objective of the present study was to characterize the height growth curve of the Mexican population by geographic area and to cluster the states of the Mexican Republic according to their somatic maturation characteristics, based on a national representative sample of boys. Data on age, height, socioeconomic level, and geographic area of 18,219 boys were obtained from the National Health and Nutrition Survey 2012 (ENSANUT) and ENSANUT 2018, carried out in 32 Mexican states.

Submandibular Skinfold Thickness Cut-off Values in Relation to Body Mass Index and Percentage Body Fat Among Chilean Adolescents.

The present study evaluates submandibular skinfold (SMS) cutoff values to estimate excess weight for BMI and percentage body fat (%BF) among Chilean adolescents. The results show an optimal area under the cutoff curve value of 83% among girls and 91% in boys to estimate SMS concerning %BF and BMI. The SMS cutoff value estimating obesity by %BF was 10 mm among girls and 9 mm among boys, 10 mm among girls, and 7 mm among boys by BMI.

Association Between Low-Grade Inflammation and Hyperuricemia in Adults With Metabolic Syndrome in Yucatán, México.

Background: Hyperuricemia (HUA) is commonly diagnosed among individuals with obesity, type 2 diabetes (T2D) and metabolic syndrome (MetS). Nevertheless, the association of HUA in individuals with MetS among the Mexican population is mostly unexplored. Low-grade inflammation has been postulated to have a key role in the pathogenesis of MetS and has been linked to insulin resistance (IR).

Maternal mortality during the COVID-19 pandemic in Mexico: a preliminary analysis during the first year.

Background: In Mexico, the COVID-19 pandemic led to preventative measures such as confinement and social interaction limitations that paradoxically may have aggravated healthcare access disparities for pregnant women and accentuated health system weaknesses addressing high-risk patients' pregnancies. Our objective is to estimate the maternal mortality ratio in 1 year and analyze the clinical course of pregnant women hospitalized due to acute respiratory distress syndrome and COVID-19.

Methods: A retrospective surveillance study of the national maternal mortality was performed from February 2020-February 2021 in Mexico related to COVID-19 cases in pregnant women, including their outcomes.

Evaluation of Anthropometric Indices and Lipid Parameters to Predict Metabolic Syndrome Among Adults in Mexico.

Background: Metabolic syndrome (MetS) is a cluster of conditions that increases the risk of cardiovascular disease (CVD) and is related to genetic background, dietary habits, and lifestyle. Anthropometric indices and lipid parameters have been shown to be simple and useful tools in clinical practice for predicting MetS. The aim of the present study was to evaluate the differential magnitudes of anthropometric characteristics (waist circumference and body mass index [BMI]) and lipid parameters, namely, lipid accumulation product (LAP), cardiometabolic index (CMI), and Castelli Risk Index (CRI-I), to estimate MetS, usingappropriate cut-off values, among adults from a public hospital in Yucatan, Mexico.

Inter-relationships between percentage body fat, relative subischial leg length and body mass index among adolescents and adults from the Limbu community of Darjeeling, West Bengal.

The main objective of this study was to evaluate the magnitude of association of percentage body fat (PBF) with relative subischial leg length (RSLL), adjusting for age, sex and body mass index (BMI), among adolescents and adults in a population of poor socioeconomic background in India. Data were taken from a cross-sectional study conducted in 2010-2014 among the Limbu community of Darjeeling, West Bengal - an indigenous community with poor socioeconomic background, low literacy rate, low income and inadequate living conditions.

Meeting Report: The Role of Beliefs and Perception on Body Size. Proceedings of the 26th Aschauer Soiree, Held at Aschauhof, Altenhof, Germany, May 26th, 2018.

Thirty-one scientists met at Aschauhof, Germany to discuss the role of beliefs and self-perception on body size. In view of apparent growth stimulatory effects of dominance within the social group that is observed in social mammals, they discussed various aspects of competitive growth strategies and growth adjustments. Presentations included new data from Indonesia, a cohort-based prospective study from Merida, Yucatan, and evidence from recent meta-analyses and patterns of growth in the socially deprived.
