LMS GROWTH CHARTS AND SITAR GROWTH CURVES – OLD DOGS AND NEW TRICKS
Tim Cole. ABSTRACT (partial): The distinguished auxologist James Tanner greatly advanced the field of human growth and development. He popularised the construction and use of growth charts – the 1966 Tanner-Whitehouse standards set a high bar for what came later. However, his way of constructing skew weight centiles was both subjective and time-consuming, until the LMS method (Cole and Green, 1992) simplified the process. Later GAMLSS (generalised additive models for location, scale and shape) (Rigby and Stasinopoulos, 2005) provided a flexible toolbox for fitting centiles to data.
GUIDANCE FOR INTERNATIONAL GROWTH STANDARDS: WHEN, WHERE, AND HOW TO APPLY INTERNATIONAL GROWTH STANDARDS
Eric Ohuma. ABSTRACT (partial): Infant growth is a commonly used proxy of population health, human capital, and socioeconomic development. Additionally, failure to achieve growth potential is associated with increased risk of mortality and morbidity throughout an individual's life.
NEUROENDOCRINE TRANSDUCTION OF SOCIAL-ECONOMICPOLITICAL-EMOTIONAL (SEPE) FACTORS THAT REGULATE HUMAN SKELETAL GROWTH
Barry Bogin. Abstract (partial): There is renewed research focus on the regulation of human growth via biocultural interactions between community networks and hormonal physiology. Human communities are networks of Social-EconomicPolitical-Emotional (SEPE) factors. SEPE factors can enhance or diminish feelings of love and hope, which in turn can promote or delay skeletal growth.
CHANGES IN NUTRITIONAL STATUS AMONG WOMEN AND INFANTS AGED 6-23 MONTHS BEFORE AND AFTER THE COVID-19 PANDEMIC IN LOW-INCOME AREAS OF TWO CITIES IN PERU
Emily Rousham. ABSTRACT (partial): Background: Peru has made significant progress in the reduction of stunting and undernutrition in children. However, malnutrition persists with high rates of anaemia, overweight and obesity and stunting. We aimed to assess whether the changing conditions over the course of the COVID-19 pandemic (lockdowns, unemployment, access to healthcare) led to changes in maternal and infant and young child (IYC) nutritional status over this period.
A PHOTOANTHROPOMETRIC STUDY: A COMPARISON OF FACIAL INDICES DERIVED FROM PROFESSIONAL AND NON-PROFESSIONAL PHOTOGRAPHS
Egle Stukaite-Ruibiene. ABSTRACT (partial): Objectives. There are facial studies including professional photographs, however, studies investigating non-professional photographs are lacking. It is important to find out if non-professional photographs could be relevant for longitudinal facial analysis, as it could allow to perform such studies cheaper and save time. The aim of this study was to compare indices obtained from professional and non-professional photographs with anthropometrically determined indices.
MIXED METHODOLOGY TO ASSESS THE RELATIONSHIP BETWEEN MULTIPLE ENDOCRINE DISRUPTING CHEMICALS AND HUMAN GROWTH AND DEVELOPMENT
Casey West. ABTSRACT (partial): There is an association between dysregulation of the endocrine system in humans and exposure to specific toxicants identified by the U.S. Environmental Protection Agency. Much human exposure is from chemicals in waste dumps and chemical processing, compounded by exposures through personal use products and ingestion of contaminated food and water.
INFANT AND CHILDHOOD GROWTH DYNAMICS: MODELLING, PRENATAL CORRELATES, AND LIFECOURSE OUTCOME
Ahmed Elhakeem. ABSTRACT (partial): Childhood obesity rates have increased fourfold in the last three decades. Growth dynamics in infancy and childhood highlight early developmental processes driving the risk of increasing adiposity. Thus, it is important to characterize early life growth and identify its correlates and outcomes.
THE ‘MUSCLE-BONE UNIT’ FROM CHILDHOOD INTO EARLY ADULTHOOD: A SITAR NONLINEAR GROWTH MODEL
Adam Baxter-Jones. ABSTRACT (partial): One approach to modelling nonlinear longitudinal data is to fit Super Imposition by Translation and Rotation (SITAR) models. Using data from the paediatric bone mineral accrual study (PBMAS, 1991-2017) we have shown that during adolescence, bone development is driven by muscle development.
THE PROPORTION OF WEIGHT GAIN DUE TO CHANGE IN FAT MASSIN INFANTS WITH VS WITHOUT RAPID GROWTH
Will Johnson. ABSTRACT (partial): Background: There is extensive evidence that rapid infant weight gain increases the risk of childhood obesity, but this is normally based on childhood body mass index (BMI) only and whether or not this is because infants with rapid weight gain accrue greater fat mass is unknown.
