The present study aimed to evaluate bone mineral density (BMD) in children and adolescents with cerebral palsy (CP) and to critically analyze the effects of a variety of factors, particularly the Gross Motor Function Classification System (GMFCS) level, the Caregiver Priorities and Child Health Index of Life with Disabilities questionnaire, and the Pediatric Outcomes Data Collection Instrument (PODCI), on BMD. Fifty patients with CP who underwent dual-energy X-ray absorptiometry were included. Collected data included the extent of involvement, muscle tone, demographic data, factors determined through chart review, and laboratory results...

Concerns about bone health and potential fragility in children and adolescents have led to a high interest in bone densitometry. Pediatric patients with genetic and acquired chronic diseases, immobility, and inadequate nutrition may fail to achieve expected gains in bone size, mass, and strength, leaving them vulnerable to fracture. In older adults, bone densitometry has been shown to predict fracture risk and reflect response to therapy. The role of densitometry in the management of children at risk of bone fragility is less clear...

OBJECTIVES: To explore the prevalence and anatomic distribution of vertebral fractures in disease groups investigated for primary and secondary osteoporosis, using vertebral fracture assessment (VFA). STUDY DESIGN: VFA was performed independently by 2 nonradiologists, in 165 children (77 males, 88 females) as part of their investigation for osteoporosis. Vertebral bodies from T6 to L4 were assessed for vertebral fractures using the Genant scoring system. The common readings for the presence of vertebral fractures were used for evaluating the prevalence and anatomic distribution of vertebral fractures...

The bone mass peak is the maximum bone quantity to be achieved through bone modeling. About 40% of the total bone mass is achieved at puberty; therefore, adolescence is critical on the skeletal development. This paper is about the transfunctional analysis of nutrition, mineral metabolism, endocrinology and life style in adolescence. Core factors to achieve the maximum potential of bone modeling through puberty and prevent osteoporosis from a pediatric stage are addressed.

Osteoporosis is one of the most common chronic forms of disability in postmenopausal women and represents a major health burden around the world. Bone fragility is affected by bone mineral density (BMD), and, one of the most important factors in preventing osteoporosis is optimizing peak bone mass, which is achieved during growth in childhood and adolescence. BMD is a complex trait resulting from environmental and genetic factors. Genome-wide association studies have discovered robust genetic signals influencing BMD in adults, and similar studies have also been conducted to investigate the genetics of BMD in the pediatric setting...

Anorexia nervosa (AN) most often has its onset in adolescence, which is a crucial period to achieve peak bone mass. The hormonal abnormalities (hypoestrogenism, hypercortisolism, decreased secretion of dehydroepiandrosterone, testosterone, insulin-like growth factor) and malnutrition are associated with profound bone mineralization disorders. Densitomertic bone mineral density (BMD) values for osteopenia and osteoporosis were found respectively in 35-98% and 13-50% of women with AN. Prospective studies indicate a further decline in BMD at the beginning of treatment and a crucial importance of weight gain and return of spontaneous menses for its growth...

: This study assessed the prevalence and types of fractures in spina bifida and examined risk factors for fracture. Fracture prevalence was highest in childhood and reduced in adolescence and young adulthood. The importance of maintaining mobility is highlighted by the increased risk of fracture in those who are non-ambulatory. INTRODUCTION: The aims of this study are to study the prevalence and types of fractures according to age group in spina bifida and examine risk factors associated with fracture...

BACKGROUND: Childhood cancer survivors are at a higher risk of developing health conditions such as osteoporosis, and cardiovascular disease than their peers. Health-promoting behaviour, such as consuming a healthy diet, could lessen the impact of these chronic issues, yet the prevalence rate of health-protecting behaviour amongst survivors of childhood cancer is similar to that of the general population. Targeted nutritional interventions may prevent or reduce the incidence of these chronic diseases...

BACKGROUND: Acute lymphoblastic leukemia (ALL) and non-Hodgkin's lymphoma (NHL) are the most common malignancies in children and adolescents. Therapies such as corticosteroids, cytotoxic and radiotherapy will have harmful effect on bone mineral density (BMD) which can lead to increased possibility of osteoporosis and pathological fractures. SUBJECTS AND METHODS: This 3-year cross-sectional study was performed in 50 children with ALL (n=25) and NHL (n=25) at Dr. Sheikh Children's Hospital in Mashhad...

Long-term use of bisphosphonates has raised concerns about the association with Atypical Femur Fractures (AFFs) that have been reported mainly in postmenopausal women. We report a case of an 18-year-old patient with juvenile osteoporosis based on X-linked osteoporosis due to a PLS3 mutation who developed a low trauma femoral fracture after seven years of intravenous and two years of oral bisphosphonate use, fulfilling the revised ASBMR diagnostic criteria of an AFF. The occurrence of AFFs has not been described previously in children or adolescents...

The number of girls participating in sports has increased significantly since the introduction of Title XI in 1972. As a result, more girls have been able to experience the social, educational, and health-related benefits of sports participation. However, there are risks associated with sports participation, including the female athlete triad. The triad was originally recognized as the interrelationship of amenorrhea, osteoporosis, and disordered eating, but our understanding has evolved to recognize that each of the components of the triad exists on a spectrum from optimal health to disease...

Health outcomes of vitamin D deficiency (VDD) are beyond rickets, osteomalacia, osteoporosis, falls and fractures and have now touched the boundaries of CVD, diabetes and many types of cancer. Therefore, thinking of mere dependence on the sun to meet vitamin D requirements under the existing set of conditions is erroneous. Pakistan as a developing economy of South Asia and a region spanning latitude 24° 35' North and longitude 61° East to 78° East, gravely suffers from increased VDD among pregnant women, neonates, infants, children, adolescents, adults, and the elderly people despite its abundant sunshine...

Atypical subtrochanteric and diaphyseal femoral fractures (AFFs) have emerged as a potential complication of bisphosphonate treatment in adults. Despite increasing off-label use of bisphosphonates in children and adolescents for a variety of skeletal disorders, there have been no reports of AFFs in children or adolescents outside of the osteogenesis imperfecta population. We present the case of a 16-year-old girl who developed a subtrochanteric femoral stress fracture following pamidronate treatment for idiopathic juvenile osteoporosis...

Sedentary behaviors such as watching television (TV) are associated with increased risk of cardiometabolic disease. The effects of TV watching during key developmental stages on skeletal health are uncertain. Hours of TV watching/week were recorded by parental or self-report at 5, 8, 10, 14, 17, and 20 years of age in 1181 members (48% female) of a pregnancy cohort (the Raine Study). Participants were classified into one of three TV-watching trajectories (using latent class analysis): low (consistently <14 h/week; 20...

Osteoporosis and cardiovascular disease(CVD) are both common causes of morbidity and mortality. Previous studies, mainly of people over 60 years, suggest a relationship between these conditions. Our aim was to determine the association between bone characteristics and CVD markers in younger and middle-aged individuals. Women (n = 3,366) and their adolescent offspring (n= 4,368) from the UK population-based cohort study, Avon Longitudinal Study of Parents and Children(ALSPAC), were investigated. We measured total body(TB) and hip BMD, TB bone area(BA) and bone mineral content(BMC) by DXA, and carotid intima-media thickness(cIMT) by high-resolution ultrasound...

As discussed in Part 1, obesity is now a global epidemic affecting a significant and rapidly increasing number of adults, adolescents, and children. As the incidence of obesity has increased, so has the use of bariatric surgery to treat it. A growing number of recently published studies have reported that, despite calcium and vitamin D supplementation, the most frequently performed types of bariatric surgery, the Roux-en-Y gastric bypass (RYGB) and the sleeve gastrectomy (SG), cause significant, ongoing bone loss...

Peak bone mass, the maximum amount of bone accrued at the end of the growth period, is an important predictor of future risk of osteoporosis and fracture. Hence, the contribution of genetic factors influencing bone accrual is of considerable interest to the osteoporosis research community. In this article, we review evidence that genetic factors play an important role in bone growth, describe the genetic loci implicated so far and briefly discuss lessons learned from the application of genome-wide association studies...

OBJECTIVE: Recent studies demonstrated an association between low serum sodium levels and reduced bone density. Patients with anorexia nervosa (AN) are at greater risk for osteoporosis as well as for hyponatremia. The aim of the present study was to assess the association between hyponatremia and bone mineral density (BMD) in a large cohort of adolescent inpatients with AN. METHODS: A historic cohort study of 174 adolescent females (mean age 15.7 ± 1.8 y) hospitalized because of AN between 2003 and 2013...
