Background: Body composition changes during the developmental period and differs in children with idiopathic scoliosis (IS). No large-scale study has been performed to reveal the link between scoliotic deformity and body composition assessed by bioimpedance method (BIA). The study objective was to correlate the extent of scoliotic-curve severity with nutritional status of patients with IS based on standard anthropometrical analysis and BIA.Material and m...

Background: Based on our recent data, nutritional status disturbances (both under- and overweight) can be associated with the severity of scoliotic curve. Objectives: The study objective was to compare two methods for the assessment of nutritional status (routine BMI calculation vs body composition analysis by bioelectrical impedance analyzer (BIA)) in the group of pediatric patients with idiopathic scoliosis (IS).Methods: 317 patients (240 girls/77 boys...

Objective: Insuficient vitamin D supply defined as serum hydroxyvitamin D (25OHD) <20 ng/ml is considered as one of possibile cardiovascular risk factors among adults with hypertension. Furthermore, some data also suggest an independent association between vitamin D deficits and hypertension and obesity during growth. The aim of the study was to assess vitamin D status in children and adolescents with hypertension.Methods: The cross sectional study w...

Vitamin D deficiency has been reported in adult patients with autoimmune diseases including rheumatoid arthritis, however, the data in patients with juvenile idiopathic arthritis (JIA) are inconsistent. The aim of the study was to assess serum 25-hydroxyvitamin D (25(OH) D in children and adolescents with JIA, and to determine potential risk factors for vitamin D deficiency.In this cross-sectional study, we evaluated 189 patients with JIA (113 girls, 76 ...

The link between scoliotic deformity and bone metabolism in adolescent idiopathic scoliosis (AIS) has not been well researched. Moreover, the data concerning the cross-talk between leptin level and bone markers in this group of patients are lacking. The objective of this study was to correlate the extent of scoliotic-curve severity with the bone turnover and leptin level in girls with AIS. The study encompassed 77 AIS girls, aged 14.7±2.17 years. Scoliotic curve severity ...

Introduction: Recently published data revealed that bone turnover is related to the body composition in pubertal children and may be impaired in obese adolescents. The aim of the study was to determine the relationship between bone turnover markers, body composition and leptin level in obese children.Material and methods: In 54 obese adolescents (25 boys and 29 girls) in the mean age of 13.96±2.78 years bone turnover markers – osteocalcin (OC),...

Introduction: Serum 25(OH)D concentrations for optimal bone metabolism in children is unknown. Only few data exist describing the effects of increasing serum 25(OH)D on bone metabolism markers.Aim: The aim of the study was to explore the association between serum 25(OH)D and bone metabolism markers in children.Patients and methods: Serum levels of bone formation (OC, P1NP) and bone resorption (CTx) markers (Cobas e411, Roche Diagno...

Introduction: The body composition at term equivalent age of infants born preterm is different than that of infants born at term.Aim: The aim of the study was to compare the body composition in preterm and full-term infants at age 3 and 4 years.Patients and methods: Total body bone mineral content (TBBMC, g), density (TBBMD, g/cm2), and body composition (fat mass – FM, g; lean body mass – LBM, g) were measured ...

Introduction: Optimal vitamin D intake for lactating women remains controversial. We hypothesized that 1200 IU/day (vs 400 IU/day) of vitamin D during breastfeeding will enhance maternal vitamin D status and bone mass.Methods: Healthy mothers after term, singleton delivery were randomized to receive vitamin D3: 1200 IU/day (800+400 IU/day from multivitamins) or 400 IU/day (placebo+400 IU/day from multivitamins) during lactation. Serum 25-hydroxyvitamin D...
