Abstract:
Objective To examine the relationship between the concentration of 25-hydroxy vitamin D3 [25-(OH) D3] in the serum and the body mass,the severity of obesity,body mass index(BMI),blood lipid,and their predicting role in obesity children.Methods The study recruited 244 subjects,who see the doctor in Wuxi Maternal and Child Health Hospital,Childhood Nutrition Outpatient from Jul.2011 to Feb.2013.The intake dose of vitamin D each day was investigated,and weight,height,BMI,concentration of 25-(OH) D3 in serum,and microelement were also measured.In addition,lipid metabolism of 38 cases with obesity over 3 years old was determined.Results 1.The serum 25-(OH) D3 concentration of obese children was (68.31 ± 23.06) nmol/L.The concentration of 25-(OH) D3 was lowest in the group of obese children over 36 months of age[(55.03 ± 15.18) nmol/L].2.The concentration of 25-(OH) D3 in the group of obese and overweight children was far lower than that of the children in the normal group (F =4.739,P ＜0.05).3.The concentrations of 25-(OH) D3 in the severely obese children was significantly lower than that of the mild and moderate obesity children(F =9.711,P ＜ 0.05).4.There were significantly inverse associations of serum 25-(OH) D3 with weight,weight and height percentage,BMI (r =-0.365,-0.237,-0.175,all P ＜ 0.001).5.There were significantly inverse associations between the concentration of 25-(OH) D3 in serum with weight,triglyceride in obese children more than 3 years old (r =0.476,-0.324,all P ＜ 0.05).Conclusions The decreasing level of 25-hydroxy vitamin D3 in the serum was associated with obesity.The cause of it might be the increase of the obese adipose tissue,vitamin D getting trapped in fat cells,and all these factors can lead to a less serum vitamin D levels.The vitamin D consumption of obese children is higher than that of normal children,and should supply more vitamin D to reach normal 25-(OH) D3 level.
