You are What Your Parents Expect: Height and Local Reference Points.

Recent estimates are that about 150 million children under five years of age are stunted, with substantial negative consequences for their schooling, cognitive skills, health, and economic productivity. Therefore, understanding what determines such growth retardation is significant for designing public policies that aim to address this issue. We build a model for nutritional choices and health with reference-dependent preferences.

Socioeconomic gradients in child development: Evidence from a Chilean longitudinal study 2010-2017.

Empirical evidence shows that lack of resources during infancy and the process of accumulating disadvantages throughout childhood have important consequences for cognitive and socio-emotional development. This paper examines socioeconomic gradients across language and socio-emotional measures. Using longitudinal data from 7-year, three-wave panel data, we study the patterns of socioeconomic status and child development in Chile and estimate how much of the wealth gap can be explained by different mediators like maternal educational and skills, child attendance of preschool and school, possession of books, or domestic violence indicators.

Hospital admissions with influenza and impact of age and comorbidities on severe clinical outcomes in Brazil and Mexico.

Background: The risk of hospitalization or death after influenza infection is higher at the extremes of age and in individuals with comorbidities. We estimated the number of hospitalizations with influenza and characterized the cumulative risk of comorbidities and age on severe outcomes in Mexico and Brazil.

Methods: We used national hospital discharge data from Brazil (SIH/SUS) from 2010-2018 and Mexico (SAEH) from 2010-2017 to estimate the number of influenza admissions using ICD-10 discharge codes, stratified by age (0-4, 5-17, 18-49, 50-64, and ≥65 years).

Barriers and facilitators to influenza vaccination observed by officers of national immunization programs in South America countries with contrasting coverage rates.

Influenza is a severe, vaccine-preventable disease. Vaccination programs across Latin American countries show contrasting coverage rates, from 29% in Paraguay to 89% in Brazil. This study explores how national influenza vaccination programs in the chosen South American countries address vaccine confidence and convenience, as well as complacency toward the disease.

Parent reported outcomes to measure satisfaction, acceptability, and daily life impact after vaccination with whole-cell and acellular pertussis vaccine in Chile.

Aim: To compare parental satisfaction and impact on daily life among parents of children receiving whole-cell pentavalent + oral polio vaccine (Arm1) with an acellular hexavalent vaccine (Hexaxim; Arm2).

Methods: Self-administered electronic questionnaire at vaccination and one week later in six community health clinics of metropolitan Santiago, Chile, exploring parent-reported outcomes on satisfaction, acceptability, and impact on daily life after immunization. Univariate and multivariate analyses were conducted to determine differences in the responses in both groups (α = 0.

Early life height and weight production functions with endogenous energy and protein inputs.

We examine effects of protein and energy intakes on height and weight growth for children between 6 and 24 months old in Guatemala and the Philippines. Using instrumental variables to control for endogeneity and estimating multiple specifications, we find that protein intake plays an important and positive role in height and weight growth in the 6-24 month period. Energy from other macronutrients, however, does not have a robust relation with these two anthropometric measures.

Waiting times for surgical and diagnostic procedures in public hospitals in Mexico.

Objective: A retrospective evaluation of waiting times for elective procedures was conducted in a sample of Mexican public hospitals from the following institutions: the Mexican Institute for Social Security (IMSS), the Institute for Social Security and Social Services for Civil Servants (ISSSTE) and the Ministry of Health (MoH). Our aim was to describe current waiting times and identify opportunities to redistribute service demand among public institutions.

Materials And Methods: We examined current waiting times and productivity for seven elective surgical and four diagnostic imaging procedures, selected on the basis of their relative frequency and comparability with other national health systems.

[IgA antibody detection and PCR as first options in the diagnosis of perinatal HIV-1 infection].

Objective: To evaluate the sensitivity and specificity of the polymerase chain reaction (PCR), enzyme-linked immunosorbent assay (ELISA) and IgA-specific immunoblot assays as ancillary methods to diagnose human immunodeficiency virus (HIV-1) perinatal infection.

Material And Methods: A comparative study was conducted between February and October 2001 at the Human Retrovirus Research Unit of Mexico's National University. Ninety infected and 153 non-infected children were included in the study.
