Head Circumference Versus Length and Weight Deficits up to 2 Years of Age in Bangladesh
Infant undernutrition, defined by length- and weight-based indices, is common in low- and middle-income countries (LMICs), but corresponding deficits in head size have received less attention. In a cohort of term newborns in Dhaka, Bangladesh, we compared the severity of deficits (vs. World Health Organization Growth Standards) in head circumference (HC), length and weight at birth and every 3 months until 2 years of age (n range across timepoint…
Associations of linear growth and weight gain in the first 2 years with bone mass at 4 years of age in children in Dhaka, Bangladesh
Objective: Growth faltering is widespread in many low- and middle-income countries, but its effects on childhood bone mass accrual are unknown. The objective of this study was to estimate associations between length (conditional length-for-age z -scores, cLAZ) and weight (conditional weight-for-age z -scores, cWAZ) gain in three age intervals (ages 0–6, 6–12 and 12–24 months) with dual-energy X-ray absorptiometry-derived measures of bone mass (to…
Complementary and alternative metrics for tracking population-level trends in child linear growth
Stunting prevalence is commonly used to track population-level child nutritional status. However, other metrics derived from anthropometric datasets may be used as alternatives to stunting or provide complementary perspectives on the status of linear growth faltering in low- and middle-income countries (LMICs). Data from 156 Demographic and Health Surveys in 63 LMICs (years 2000 to 2020) were used to generate 2 types of linear growth metrics: (i)…
The impact of Muslim and Christian religious leaders responding to Covid-19 in Israel
Background: The COVID-19 pandemic is one of the most significant public health emergencies in decades and has affected all countries worldwide. Religious leaders have been recognized as playing a pivotal role in health promotion during times of crisis. This study explored the role that Muslim and Christian religious leaders played in Israel during the pandemic, and the impact that their activities had on the community. Methods: A qualitative stud…
Growth delay
GD is a population-level measure of child health that reflects the role of delayed skeletal development in linear growth faltering
Third-Party Peacemakers in Judaism
Third-Party Peacemakers in Judaism presents thirty-six case studies featuring third-party peacemakers found within Jewish rabbinic literature. Each case study is explored through three layers of analysis: text, theory, and practice. The textual analysis consists of close literary and historical readings of legends and historical accounts as found within classical, medieval, and early-modern rabbinic literature, many of which are critically analyz…
A novel development indicator based on population-average height trajectories of children aged 0–5 years modelled using 145 surveys in 64 countries, 2000–2018
INTRODUCTION: Children's growth status is an important measure commonly used as a proxy indicator of advancements in a country's health, human capital and economic development. We aimed to assess the feasibility of using Super-Imposition by Translation And Rotation (SITAR) models for summarising population-based cross-sectional height-by-age data of children under 5 years across 64 countries. METHODS: Using 145 publicly available Demographic and …
Association of maternal prenatal selenium concentration and preterm birth
BACKGROUND: Selenium (Se), an essential trace mineral, has been implicated in preterm birth (PTB). We aimed to determine the association of maternal Se concentrations during pregnancy with PTB risk and gestational duration in a large number of samples collected from diverse populations. METHODS: Gestational duration data and maternal plasma or serum samples of 9946 singleton live births were obtained from 17 geographically diverse study cohorts. …
Physical Activity and the Home Environment of Pre-School-Aged Children in Urban Bangladesh
Physical activity (PA) is a key determinant of health and development, yet few studies have examined PA levels and risk factors for low PA among young children in low- and middle-income countries. This study aimed to describe the PA and sedentary (SED) behavior levels of preschool-aged children in Dhaka, Bangladesh, and to estimate the associations between potential risk factors in the home built environment and moderate to vigorous PA (MVPA). In…
Conditional random slope
OBJECTIVES: Conditioning child growth measures on baseline accounts for regression to the mean (RTM). Here, we present the "conditional random slope" (CRS) model, based on a linear-mixed effects model that incorporates a baseline-time interaction term that can accommodate multiple data points for a child while also directly accounting for RTM. METHODS: In two birth cohorts, we applied five approaches to estimate child growth velocities from 0 to …
Prenatal vitamin D supplementation and infant vitamin D status in Bangladesh
Objective To determine the effect of prenatal maternal vitamin D supplementation on infant vitamin D status in a tropical region where vitamin D supplementation is not routine. Design A prospective observational follow-up of a randomized trial. Setting Maternal–child health facility in Dhaka, Bangladesh (23°N). Subjects Infants born to pregnant women ( n 160) randomized to receive 875 μg (35 000 IU) cholecalciferol (vitamin D 3 ) per week (VD) or…
Maternal vitamin D status and infant anthropometry in a US multi-centre cohort study
Low maternal vitamin D status was associated with deficits at birth in infant weight and BMI that were recouped across the first year of life; associations with reduced measures of linear and skeletal growth were sustained from birth to 12 months
Are National Vitamin D Guidelines Sufficient to Maintain Adequate Blood Levels in Children
Which Way Cognitive Development
The article addresses the current status of Piaget's theory as a perspective on the nature of the human intellect and its development. As a framework for discussion, we adopt Lakatos's methodology of research programs, which has been used by several authors to debate the role of Piaget's and other perspectives on cognitive development. The position we advocate is that, in recent years, research in cognitive development has undergone a profound ch…
