We conducted semi-structured interviews and followed a thematic analysis framework. Maternity care providers' knowledge, attitudes, and practices regarding calcium supplementation during pregnancy are linked to barriers to the potential implementation of calcium supplementation.

Predictive Equations Overestimate Resting Metabolic Rate in Young Chilean Women with Excess Body Fat.

Underestimating/overestimating resting metabolic rate (RMR) affects energy prescription. The objective was to compare RMR by indirect calorimetry (RMR IC) and RMR estimated by predictive equations in women with excess body fat. This was an analytical cross-sectional study with 41 women aged 18-28 with overnutrition according to body composition.

Are and Isolated from Powdered Infant Formula a Hazard for Infants? A Genomic Analysis.

Powdered infant formulas (PIF) are the most used dietary substitutes that are used in order to supplement breastfeeding. However, PIF are not sterile and can be contaminated with different microorganisms. The objective of this study was to genomically characterize (ENT) and strains that were isolated from PIF.

Association between Homophobia and Sociodemographic Characteristics in Health Workers in Southern Chile.

Homophobic attitude in health workers is a social determinant in the health of the homosexual population because it affects healthcare and its access and equity. The objective was to determine the relationship between the level of homophobia and sociodemographic characteristics of primary health workers in southern Chile. This was an analytical cross-sectional study.

Chilean reference of length at birth.

Background: To generate a reference of length at birth (LB) according to sex and gestational age (GA) of the Chilean population.

Methods: This cross-sectional observational study used public pooled Chilean newborn (NB) population data registered by the Civil Registry and Identification Service in Chile from 2000 to 2016. Multiple births, entries without information for LB, GA, and sex, and birth lengths <-4SD and > 4SD, were excluded.

Maternal Factors Associated with Non-Exclusive Breastfeeding in Haitian Immigrant Women in Southern Chile.

There is limited knowledge concerning factors that affect non-exclusive breastfeeding (NEBF) practices in immigrant populations, especially in Latin America. The objective of the present study was to determine the association between maternal factors and the prevalence of NEBF in Haitian immigrant women in southern Chile. This was an analytical cross-sectional study.

Association between Maternal Factors, Preterm Birth, and Low Birth Weight of Chilean Singletons.

There has been an increase in preterm (PT) births in Western countries in recent years, which is associated with low-birthweight (LBW) children. The aim of this study was to determine the association between maternal factors and PT and LBW Chilean newborns. Methods: This was an analytical cross-sectional study of a national sample of 903,847 newborns and their mothers.

Obese Women Have a High Carbohydrate Intake without Changes in the Resting Metabolic Rate in the Luteal Phase.

Hormonal changes are caused by the menstrual cycle phases, which influence resting metabolic rate and eating behavior. The aim of the study was to determine resting metabolic rate (RMR) and its association with dietary intake according to the menstrual cycle phase in lean and obese Chilean women. This cross-sectional analytical study included 30 adult women (15 lean and 15 with obesity).

Association of Prematurity and Low Birth Weight with Gestational Exposure to PM and PM Particulate Matter in Chileans Newborns.

Fetal growth can be affected by gestational exposure to air pollution. The aim of the study was to determine the association between prematurity and low birth weight (LBW) with gestational exposure to PM2.5 and PM10 particulate matter in Chileans newborns.

Profiling the Virulence and Antibiotic Resistance Genes of Strains Isolated From Powdered and Dairy Formulas by Whole-Genome Sequencing.

is an enteropathogen that causes neonatal meningitis, septicemia, and necrotizing enterocolitis in preterm infants and newborns with a mortality rate of 15 to 80%. Powdered and dairy formulas (P-DF) have been implicated as major transmission vehicles and subsequently the presence of this pathogen in P-DF led to product recalls in Chile in 2017. The objective of this study was to use whole genome sequencing (WGS) and laboratory studies to characterize strains from the contaminated products.

Presence of in Ready-to-Eat Artisanal Chilean Foods.

Ready-to-eat (RTE) artisanal foods are very popular, but they can be contaminated by . The aim was to determine the presence of in artisanal RTE foods and evaluate its food safety risk. We analyzed 400 RTE artisanal food samples requiring minimal (fresh products manufactured by a primary producer) or moderate processing (culinary products for sale from the home, restaurants such as small cafés, or on the street).

Association between high pre-pregnancy body mass index, excess gestational weight gain, and poor breastfeeding with overweight in 3-4-year-old Chilean children.

Objective: The aim of this study was to determine the association between prepregnancy body mass, gestational weight gain, and inadequate breastfeeding (BF) with overweight in Chilean children ages 3 to 4 y.

Methods: This was an analytical and cross-sectional study with 560 participants. Age, residence, BF, and weight gain information were collected from child care records.

Microbiological Quality of Powdered Infant Formula in Latin America.

Abstract: Cronobacter is a bacterial genus that includes seven species, and the species Cronobacter sakazakii is most related to meningitis and septicemia in infants associated with powdered infant formula (PIF). The objectives of this study were to evaluate the presence of C. sakazakii and to determine the microbiological quality of PIF for infant consumption.

Association between body mass index and functional fitness of 9- to 10-year-old Chilean children.

Objective: This study aimed to determine the association between body mass index (BMI) and functional fitness (FF) in 9- to 10-year-old Chilean children.

Methods: This was an analytical and cross-sectional study with a probabilistic sample consisting of 139 children of both sexes. Anthropometric measurements, hemodynamic variables, physical activity (PAQ-C), and FF (measured by a 6-minute walk test: 6MWT) were recorded.
