Background: Osteocalcin is a metabolic active hormone, which correlates positively with bone formation and inversely with body mass index and waist circumference in adults.
Objectives: To investigate whether osteocalcin in infancy and early childhood were related to childhood growth or body composition.
Methods: A Swedish longitudinal birth cohort with blood samples from 551 children from birth until 5 years of age.
Purpose: Adults with neurodevelopmental disorders have an increased risk for chronic pain. This study aimed to describe the prevalence of frequent and multisite pain among children with symptoms of attention deficit hyperactivity disorder (ADHD) and explore potential sex differences in pain prevalence.
Participants And Methods: Children born in 2008 included in the "Halland Health and Growth Study" were invited to a follow-up (n = 1186) in 2018-19.
Objective: The longitudinal variations in serum levels of the hormone osteocalcin is largely unknown during infancy and early childhood. Our aim was to establish reference limits for total serum osteocalcin during specific time points from birth until 5 years of age and present those in the context of sex, breastfeeding practices and gestational age (GA).
Design: Blood samples from 551 Swedish children were analysed at birth, 4, 12, 36 and 60 months of age.
Introduction: Physical activity (PA), exercise, sedentary behavior and screen time are lifestyle factors that have been shown to significantly impact child health in different ways. These lifestyle factors were affected to different degrees by global restrictions during the COVID-19 pandemic. We investigated PA and screen time in a cohort of Swedish children in both 2019 and 2021, before and during the pandemic.
