The Association between Overweight and Some Biological Markers among Fewer than 6 Years Aged Children

Abstract

Body mass index (BMI)is an important indicator of overweight and obesity in childhood and adolescence. When measurements are taken carefully and compared with appropriate growth charts and recommended cutoffs, BMI provides an excellent indicator of overweight and obesity that is sufficient for most clinical, screening, and surveillance purposes. Accurate measurements of height and weight require that adequate attention be given to data collection and management. Recent years have seen a rapid increase in the incidence of obesity in children and adolescents, leading to widespread concern.Obesity is a significant health problem world-wide, particularly in developed nations it is often associated with vitamin D deficiency and secondary hyperparathyroidism. The roles of vitamin D , and parathyroid hormone (PTH) are discussed controversially in obesity, and studies of these hormones in obese children are limited. Therefore, we studied the relationships between PTH, vitamin D (25-OH) , weight status, and calcium before and um level in Iraqi patients Patients and Methods: This study assessed 45  overweight/obese children and 30 healthy (control) children .The distributions of Age , gender , serum 25-hydroxyvitamin D (25(OH)D) concentration  PTH and calcium level were compared among different groups Results: The serum 25-hydroxyvitamin D (25(OH)D) concentration  , calcium level was significantly lower (p< 0.05)   in overweight/obese children as compared with control group  while the  parathyroid hormone and body mass index was  showed significantly higher(p< 0.05)  in overweight/obese children as compared with control group Conclusions: This studies was showed an association between calcium , parathyroid hormone and vitamin D with childhood obesity. So the Children with obesity have higher risk of vitamin D deficiency
