BACKGROUND/OBJECTIVES: An appreciation of infant body composition is helpful to understand the 'quality' of growth in early life. Air displacement plethysmography (ADP) using PEA POD and the deuterium dilution (DD) technique are commonly used body composition approaches in infants. We evaluated the comparability of body composition assessed using both techniques with two-compartment (2C) and three-compartment (3C) models in 6-month-old infants. SUBJECTS/METHODS: Infant fat mass (FM) and percent fat mass (%FM) obtained from a 2C model using PEA POD (2C-PP) and a 2C model using the deuterium dilution technique (2C-DD) were compared to those derived from a 3C model, and to each other, using Bland-Altman analysis and Deming regression...

Peroneal neuropathy and polyneuropathy are displayed with a variable percentage in subjects affected by eating disorders and in particular by anorexia nervosa. Actually, little is known on features of these complications during the paediatric age. We describe the case of a female adolescent with right peroneal palsy and subclinical polyneuropathy associated with anorexia nervosa (AN). We review previous research about peroneal mononeuropathy and polyneuropathy associated with AN, and we develop a diagnostic and therapeutic protocol to help clinicians recognize and treat these disorders...

BACKGROUND: Obesity is an important and growing health problem whose treatment involves dietary changes. In this context, studying the role of macronutrients in weight loss is required in order to understand which strategies may be applied for weight loss. We aimed to evaluate the effects of diets rich in polyunsaturated (PUFAs) and monounsaturated fatty acids (MUFAs) on resting energy expenditure (REE), substrate oxidation, and weight loss in women with obesity. METHODS: Randomized, controlled, single blind, parallel-group clinical trial was conducted for 60 days...

INTRODUCTION: While lifelong and strict adherence to gluten-free diet (GFD) is essential for the successful treatment of celiac disease (CeD), only 30-50% of patients are able to maintain a good adherence to GFD. We determined factors influencing the adherence to GFD at various ecological levels including intra-personal, inter-personal, organizational, community and system-based levels in adult patients with CeD. METHODS: A questionnaire to assess the adherence was developed and it was administered in the CeD clinic to patients with CeD on GFD for >1 year...

Dietary nitrates are thought to confer several cardiometabolic health benefits, including improvements in blood pressure and the plasma lipid profile. However, existing data from Iran is conflicting and there is a dearth of literature focusing on non-adult populations. A total of 988 adolescent girls were recruited from schools in different areas of Mashhad and Sabzevar, Iran. Dietary nitrate intake was assessed using a food frequency questionnaire and participants were categorized into quartiles based on this...

BACKGROUND: Outliers can influence regression model parameters and change the direction of the estimated effect, over-estimating or under-estimating the strength of the association between a response variable and an exposure of interest. Identifying visit-level outliers from longitudinal data with continuous time-dependent covariates is important when the distribution of such variable is highly skewed. OBJECTIVES: The primary objective was to identify potential outliers at follow-up visits using interquartile range (IQR) statistic and assess their influence on estimated Cox regression parameters...

There is currently no consensus on the guidelines for vitamin D prophylaxis in healthy children. The purpose of this study was to investigate the prescribing behaviour of vitamin D prophylaxis among Belgian paediatricians. Between June and September 2022, a questionnaire was distributed by email to all Belgian paediatricians who are a member of at least one of three scientific or professional organisations, as well as to the heads of every Belgian paediatric or neonatal hospital ward. We analysed 426 completed questionnaires...

BACKGROUND: Given the importance of infancy for establishing growth trajectories, with later-life health consequences, we investigated longitudinal body composition among infants from six economically and ethnically diverse countries. METHODS: We recruited mother-infant dyads using the WHO Multicenter Growth Reference Study criteria. We measured fat-free mass (FFM) in 1393 (49% female) infants from birth to 6 months of age (Australia, India, and South Africa; n = 468), 3-24 months of age (Brazil, Pakistan, South Africa, and Sri Lanka; n = 925), and derived fat mass (FM), fat mass index (FMI), and fat-free mass index (FFMI)...

Abdominal obesity, regardless of overall obesity, is associated with metabolic abnormalities and with direct impact on cardiovascular risk. The aim of this study was to compare body mass index (BMI), waist circumference (WC), and waist-to-height ratio (WHtR) to estimate cardiovascular disease (CVD) prevalence in individuals with chronic kidney disease (CKD). The data analyzed is from 2005-2016 cycles of the NHANES. A total of 2,825 participants with CKD were included in this study, and most of them had a high BMI, 66...

OBJECTIVE: The existence of seasonal changes in energy metabolism is uncertain. We investigated the relationship between the seasons and spontaneous physical activity (SPA), energy expenditure (EE), and other components measured in a respiratory chamber. METHODS: Between 1985-2005, 671 healthy adults (aged 28.8 ± 7.1 years; 403 men) in Phoenix, Arizona had a 24-hour stay in the respiratory chamber equipped with radar sensors; SPA (expressed as a percentage over the time interval), the energy cost of SPA, EE, and respiratory exchange ratio (RER) were measured...

BACKGROUND/OBJECTIVE: A successful Long-Term Weight Loss (LTWL) is associated with a more favorable metabolic disease risk profile. However, evidence is limited on the association of LTWL with obesity-related complications defined by Edmonton obesity staging system (EOSS). Hence, our study aims to assess the association between LTWL thresholds and obesity-related complications defined by EOSS among the adult US population. SUBJECTS/METHODS: We used data from the National Health and Nutrition Examination Survey (NHANES) from 2011 to 2018...

OBJECTIVE: To validate a short food frequency questionnaire (screener) estimating daily average calcium intake from dietary sources to guide calcium supplementation of patients with osteoporosis in clinical practice. METHODS: An eight-item calcium screener was developed based on existing literature, food consumption data and expert opinion. Convergent validity was determined by comparison with 3-day food records using mean difference, Spearman's correlation coefficients (SCC) and Bland-Altman analysis...

OBJECTIVES: Maximum grip strength (mGS) is a useful predictor of health-related outcomes in children and adults. The aim of the study was to generate sex- and age-adjusted reference centiles for mGS for children, adolescents and young adults, while adjusting for body height and body mass index (BMI). METHODS: A retrospective analysis of longitudinal data from children and young adults participating in the DOrtmund Nutritional and Anthropometric Longitudinally Designed (DONALD) study (single center, open cohort study) from 2004 to 2022 was conducted...

Currently available anthropometric body composition prediction equations were often developed on small participant samples, included only several measured predictor variables, or were prepared using conventional statistical regression methods. Machine learning approaches are increasingly publicly available and have key advantages over statistical modeling methods when developing prediction algorithms on large datasets with multiple complex covariates. This study aimed to test the feasibility of predicting DXA-measured appendicular lean mass (ALM) with a neural network (NN) algorithm developed on a sample of 576 participants using 10 demographic (sex, age, 7 ethnic groupings) and 43 anthropometric dimensions generated with a 3D optical scanner...

BACKGROUND/OBJECTIVES: In addition to the potential effects of nutrients on mood, eating behaviors have been suggested to be associated with depressive symptoms. We investigated the prospective association between the accumulation of unhealthy eating behaviors and depressive symptoms in a Japanese working population. METHODS: Participants were 914 workers (aged 19-68 years) who did not have depressive symptoms at baseline (April 2012 and May 2013) and attended a 3-year follow-up survey (April 2015 and May 2016)...

BACKGROUND & AIMS: Metabolic flexibility (MetF) is considered a metabolic health biomarker, as excess body weight is associated with lower MetF. We aimed to identify whether MetF indexes were associated with cardiometabolic risk factors before and after adjustment for body size-related factors (body weight, fat-free mass, and resting metabolic rate). METHODS: We studied 51 participants (55% women; 33.6 ± 8.7 years; 26.3 ± 3...
