ABSTRACT
Objective@#To investigate the influence of change in blood pressure status from childhood to adulthood on renal damage.@*Methods@#Data were obtained from Beijing Blood Pressure Cohort initiated from 1987. 3 198 children and adolescents aged 6-18 years from 6 primary and 6 middle schools in Chaoyang, Xicheng and Haidian Districts of Beijing were enrolled at baseline by using a cluster random sampling method, and 1 222 participants were followed up during 2010-2012. The measurements included weight, height, and blood pressure at baseline and microalbumin, serum creatinine, cystatin C and blood pressure at follow-up. Based on blood pressure status in childhood and adulthood, the participants were divided into four groups: participants with normal blood pressure in both childhood and adulthood, participants with elevated blood pressure in childhood but normal blood pressure in adulthood, participants with normal blood pressure in childhood but elevated blood pressure in adulthood, and participants with elevated blood pressure in both childhood and adulthood. Multivariate linear regression model was used to investigate the association of change in blood pressure from childhood to adulthood on renal dysfunction.@*Results@#The prevalence of elevated blood pressure in childhood and adulthood was 17.9% and 39.9%, respectively. The P50 (P25-P75) of microalbumin was 5.7(3.0-12.0) mg/L, and the concentration of eGFR and cystatin C were (118.0±19.8)% and (0.734±0.184)mg/L, respectively. With adjustment for sex, baseline age and follow-up years, compared with participants with persistently normal blood pressure from childhood to adulthood, participants with normal blood pressure in childhood but elevated blood pressure in adulthood had significantly higher levels of microalbumin (β=0.502, 95%CI: 0.320-0.684) and cystatin C (β=0.049, 95%CI: 0.025-0.073). After adjustment for sex, baseline age, follow-up duration, and adult BMI, smoking and drinking, participants with normal blood pressure in childhood and elevated blood pressure in adulthood had higher levels of adult urine microalbumin (β=0.322, 95%CI: 0.128-0.516) and cystatin C (β=0.032, 95%CI:0.007-0.057).@*Conclusion@#An increase in blood pressure during childhood and adulthood has an adverse impact on renal functional damage in adulthood. These findings underscore the importance of maintaining normal blood pressure during life course to prevent the development of chronic kidney disease.
ABSTRACT
Objective To examine the value of child and adolescent Korotkoff phase Ⅳ(K4)and Korotkoff phaseⅤ(K5)diastolic blood pressures for predicting subclinical cardiovascular disease(CVD)in adulthood.Methods The data was obtained from the Beijing Children Blood Pressure Study.A total of 3 198(1 700 males,53.2%)healthy children aged 6-18 years from 6 districts in Beijing in 1987 were selected.The physical examination process included measuring height,weight,and blood pressure.From a follow-up survey in 2010-2012,1 252 subjects were analyzed by the same measurements (height,weight and blood pressure)and also by using subclinical markers for vascular damage,including carotid intima-media thickness (cIMT)and carotid-femoral pulse wave velocity (cfPWV).Childhood hypertension at baseline and adulthood hypertension were diagnosed according to the China Guideline for Hypertension Prevention and Control issued in 2010.High cfPWV and high cIMT were defined in adults as having higher than age and gender-specific 75th percentile of cfPWV and cIMT.Pearson correlation coefficients were calculated to describe the association of K4 and K5 in childhood with systolic blood pressure(SBP),diastolic blood pressure(DBP),cfPWV, and cIMT in adulthood.Logistic regression was used to analyze the values of K4 and K5 to predict subclinical CVD in adulthood.Results The baseline mean value of K4 DBP was (66.4 ± 9.1)mmHg (1 mmHg=0.133 kPa)and K5 DBP was (54.1 ± 11.1)mmHg.The prevalence rates of high-normal blood pressure were 9.4% with DBP measured by using K4,and 6.9% with DBP measured by using K5,respectively. The prevalence rates of hypertension were 11. 3% with DBP measured by using K4,and 8.4%with DBP measured by using K5.After adjustment for age and follow-up age,Pearson correlation analyses showed K4 DBP and K5 DBP in childhood were all significantly associated with adult SBP,DBP,cIMT,cfPWV in males and in females (all P<0.05).K4 in childhood was better correlated with SBP,DBP,cIMT and cfPWV in adulthood than K5.With multi-factor logistic regression analysis,K4 was better than K5 in predicting CVD in adulthood after controlling gender and age.Further K4 was more effective in predicting cfPWV than cIMT.Conclusions There was a significant difference between K4 and K5 in Chinese children and adolescents. K4 in childhood was better correlated with CVD in adults than K5,and K4 is superior to K5 when using auscultator technique to measure DBP.
ABSTRACT
Objective@#The present study aimed to prospectively validate whether the single nucleotide polymorphisms (SNPs) in obesity-related genes were associated with change in body mass index (BMI) and obesity status during childhood.@*Methods@#Based on the Beijing Child and Adolescent Metabolic Syndrome study (BCAMS), which was initiated between April and October in 2004, we conducted a follow-up study among 1 624 children aged 6 to 11 years old with genetic data in December 2010. A total of 777 children (246 obese and 531 non-obese) were reassessed for BMI. Z-score of BMI was used to standardize for age and sex. The changes in BMI Z-score during follow up were calcnlated SNPs were genotyped by quantitative Real-time PCR (rs9939609, rs6499640, rs7138803, rs1805081, rs17782313, rs6265, rs10938397, rs6235, rs29941, rs2844479, rs10913469 and rs4788102). Overweight and obesity were diagnosed by the age-and sex-specific BMI cutoffs recommended by the International Obesity Task Force. A multilocus genetic risk score for BMI was calculated as the simple sum of alleles of all the SNPs associated with BMI. Linear regression models and logistic regression models were performed to assess the associations of change in BMI Z-score and obese status with genotypes (assuming an additive model), respectively.@*Results@#During 6 years of follow-up, 158 previously obese children remained obese as they aged into adolescence, and 88 transiently obese children were not obese during the second survey, 58 children were newly identified obese, and the other 473 children remained their non-obese state. BMI Z-score increased from 1.41±0.05 at baseline to 1.57±0.06 at follow up.The genotypes of the SNPs except rs6499640(P=0.033) and rs6265(P=0.041) were in Hardy-Weinberg equilibrium in each group (P>0.05). Each additional copy of the rs9939609 A allele was significantly associated with an increase in BMI Z-score (β=0.205, P=0.014) during follow up. Per C allele of rs17782313 was associated with an increase in BMI Z-score at baseline (β=0.268, P=0.003). As the non-obese reference, a significantly relative risk of obesity at follow up was observed for children carrying rs9939609 A-allele versus the T-allele carriers (OR=2.37, 95%CI: 1.45-3.88, P=0.001). Rs17782313 C-allele was significantly increase the risk of obesity only at baseline (OR=1.79, 95%CI: 1.24-2.60, P=0.002). Rs1805081 A-allele was significantly associated with durative of obesity (OR=1.45, 95%CI: 1.04-2.03, P=0.028). Each unit higher genetic risk score was associated with increases risk of 0.18 times (OR=1.18, 95%CI: 1.05-1.33) in childhood transient obesity, and 0.22 times (OR=1.22, 95% CI: 1.06-1.42) in incident obesity at follow-up. But it was not significantly associated with persisted obesity during 6 years of follow-up (OR=1.09, 95% CI: 0.99-1.20).@*Conclusion@#We confirmed that the change of BMI and obesity status in children was affected by different genetic factors. Individual who carries more risk alleles in obesity-related genes may increase the susceptibility to obesity.
ABSTRACT
<p><b>OBJECTIVE</b>To examine the prevalence of obesity phenotypes and cardiometablic disorders (CDs) among children aged 6- 17 in Beijing from 2004 to 2013.</p><p><b>METHODS</b>Data were obtained from two cross-section surveys, which were conducted in 2004 and 2013. In 2004, by using stratified cluster sampling design, 20 primary or middle schools were selected from 7 districts (Xicheng, Dongcheng, Chaoyang, Haidian, Daxing, Pinggu, and Yanqing) in Beijing, and 20 554 school children aged 6-17 were recruited, with weight, height, waist circumference and blood pressure measured. Fasting plasma glucose (FPG), total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), and low density lipoprotein cholesterol (LDL-C) were measured in 962 subjects from one school. In 2013, by using the same sampling design, 7 211 students from two districts (Haidian and Dongcheng) were surveyed with weight, height, waist circumference and blood pressure measured, and fasting plasma glucose and lipid profile (TC, TG, HDL-C, LDL-C) were measured for 1 344 subjects in the same school measured in 2004. Student's-t test was used to analyze the difference in body mass index(BMI), WC, and waist to height ratio (WHtR) among children between 2004 and 2010. Chi-square test was used to analyze the difference of hypertension, impaired fasting glucose(IFG), dyslipidemia, and metabolic disorders clustering between 2004 and 2010, and among different types of obesity; logistic regression model was used to analyze the association between three types of obesity and risks of cardiovascular metabolic disorders.</p><p><b>RESULTS</b>In boys, BMI ((20.3 ± 4.4) vs (19.4 ± 4.2) kg/m(2), t=11.18, P<0.001), WC ((70.6 ± 12.8) vs (66.7 ± 11.8) cm, t=17.20, P<0.001) and WHtR (0.451 ± 0.064 vs 0.437 ± 0.059, t=11.64, P<0.001) were significantly higher in 2013 than those in 2004. Similarly in girls, BMI ((18.9 ± 3.6) vs (18.7 ± 3.7) kg/m(2), t=12.21, P<0.001), WC ((64.5 ± 9.6) vs (63.0 ± 9.3) cm, t=8.15, P<0.001) and WHtR (0.430 ± 0.047 vs 0.423 ± 0.047, t=14.13, P<0.001) were also significantly higher in 2013 than those in 2004. The prevalence of combined obesity rose from 8.27% (1 697/20 526) in 2004 to 10.74% (774/7 209) in 2013, and central obesity from 3.08% (632/20 526) to 4.44% (320/7 209). The prevalence of hypertension (10.78%(313/1 344) vs 4.29% (42/962), χ(2)=36.76, P<0.001), IFG(49.54%(664/1 344) vs 6.45%(63/962), χ(2)=506.61, P<0.001), high TC(11.53%(155/1 344) vs 5.03%(49/962), χ(2)=28.31, P< 0.001), high TG(7.51%(101/1 344) vs 3.59%(35/962), χ(2)=29.59, P<0.001) were significantly higher in 2013 than those in 2004. Subjects with combined obesity had higher risks of hypertension (OR=5.88, 95% CI: 4.42-7.82), high TG (OR=7.12, 95%CI: 4.35-11.64), low HDL-C (OR=3.04, 95%CI: 1.55-5.95), high LDL-C (OR=2.27, 95% CI: 1.22-4.02), CDs≥2 (OR=3.07, 95% CI: 2.09-4.50), comparing to children without obesity.</p><p><b>CONCLUSION</b>The prevalence of types of obesity and obesity-related metabolic disorders, except for low HDL-C and high HDL-C, were significantly higher in 2013 than those 2004 among chlildren aged 6-17 year in Beijing. Children with combined obesity had higher prevalence of metabolic disorders.</p>

<p><b>OBJECTIVE</b>To observe the effect of childhood excessive adiposity on long-term risk of adult carotid atherosclerosis and arterial stiffness.</p><p><b>METHODS</b>At baseline, in 1987, by using stratified cluster sampling design, 3 198 healthy children aged 6-18 were recruited from six primary schools and six middle schools from three districts (Chaoyang, Xicheng, and Haidian) in Beijing, with blood pressure, weight, height and left scapular skinfold thickness (LSSF) measured. From April 2010 to July 2012, 1 225 subjects were followed from childhood to adulthood. Questionnaire, biochemistry parameters, carotid-femoral pulse wave velocity (cfPWV), and carotid intima media thickness (cIMT) were measured at follow-up. Based on weight statuses in childhood and adulthood, subjects were classified into four groups (persistent non-overweight from childhood to adulthood, overweight in childhood but non-overweight in adulthood, non-overweight in childhood but overweight in adulthood, persistent overweight from childhood to adulthood). Multiple logistic regression model was used to analyze the association between weight statuses changing from childhood to adulthood and adult high cfPWV and high cIMT.</p><p><b>RESULTS</b>The prevalence of overweight (including obesity) at adulthood was 52.2% (639). Males had higher prevalence of smoking (62.5%(422/675) vs 29.4%(160/550), χ(2)=133.21, P<0.001), drinking (52.1%(353/675) vs 26.1%(140/550), χ(2)=87.13, P<0.001), overweight (including obesity) (69.3% (468/675) vs 31.1% (171/550), χ(2)=182.18, P< 0.001) than females. With adjusting for gender, age, and length of follow-up, the risk of high cfPWV and high cIMT increased by 26% and 58% for 1 units increase in BMI, and by 30% and 36% for 1 units increase in LSSF. Compared to subjects with persistent non-overweight from childhood to adulthood, subjects with overweight in childhood but non-overweight in adulthood had similar risks of high cfPWV (OR=1.59, 95%CI: 0.77-3.30)and high cIMT (OR=1.47, 95%CI:0.65-3.31). The risks of high cfPWV and high cIMT increased among subjects with non-overweight in childhood but overweight in adulthood (OR=1.92, 95%CI:1.37-2.68; OR=3.69, 95% CI:2.61- 5.23) and among subjects with persistent overweight from childhood to adulthood (OR=2.53, 95%CI:1.70-3.76; OR=5.37, 95%CI:3.62-7.97).</p><p><b>CONCLUSIONS</b>We concluded that a overweight children changed to a healthy weight adult, the risks of adult subclinical atherosclerosis and arterial stiffness would not be increased.</p>

<p><b>OBJECTIVE</b>To investigate the correlation between obesity in children and diabetes in adults from a cohort study, and further more to explore the necessity of preventing diabetes by controlling obesity in children.</p><p><b>METHODS</b>In 1987, 3 198 children and adolescents aged 6-18 were recruited from 6 elementary schools and 6 high schools located in 3 districts (Chaoyang, Haidian, and Xicheng) of Beijing using stratified cluster sampling design. The physical examination process included physical development test, blood pressure measurement, and questionnaire investigation. All children were invited to participate in the study, except for those who had history of congenital heart disease, chronic kidney disease, and limb disability. A total of 1,225 adults were enrolled in a prospective follow-up study from March 2010 to July 2012, anthropometric measures and blood sample were obtained. The obesity was defined by the following criteria: for children aged 6, the age-and the gender-specific 95th percentile of BMI from the US Centre for Disease Control and Prevention Growth charts 2000 as the baseline; for children age 7-18, recommendation from Working Group on Obesity in China (WGOC) as the standard; for adults, BMI≥28 kg/m(2) as the diagnosis standard. Diabetes was defined based on fasting plasma glucose(FPG) ≥7.0 mmol/L or 2 hours postprandial blood glucose (2 h PG) ≥11.1 mmol/L or glycosylated hemoglobin (HbA1c) ≥6.5% or current using blood glucose-lowering agents or current using insulin. Logistic regression was used to analyze the association obesity in children with diabetes in adults.</p><p><b>RESULTS</b>The prevalence of diabetes diagnosed by FPG and 2 h PG in adults who were obese children (16.2%, 18/111) was higher than those who were non-obese children (5.6%, 62/1,114)(χ(2)=18.76, P<0.001). The prevalence of diabetes diagnosed by HbA1c in adults who were obese children(18.1%,20/111) was higher than those who were non-obese children (6.9%, 77/1,114) (χ(2)=16.66, P<0.001). With multi-factor logistic regression analysis, we found that after controlling follow-up age, genders and lifestyle (smoking, alcohol consuming, dietary, and sleeping), in comparison with those non-obese from childhood to adulthood, those obese only in childhood or only in adulthood did not predict any risk of diabetes diagnosed by blood glucose in adults (OR(95%CI) were 1.90 (0.86-4.19), 1.71(0.50-5.79), respectively). Those obese both in childhood and in adulthood increased the risk of diabetes diagnosed by blood glucose in adults (OR(95%CI) was 4.50(2.22-9.14)). With multi-factor logistic regression analysis, we found that after controlling age, sex and lifestyle (smoking, alcohol consuming, dietary, and sleeping) in comparison with those non-obese from childhood to adulthood, those obese only in childhood or only in adulthood did not increase the risk of diabetes diagnosed by HbA1c in adults (OR(95%CI) were 1.42(0.71-2.86), 3.13(0.83-11.75), respectively). Those obese both in childhood and in adulthood increased the risk of diabetes diagnosed by HbA1c in adults (OR(95%CI) was 5.93(3.06- 11.49)).</p><p><b>CONCLUSION</b>Obesity in children even sustained to adulthood was a risk factor for diabetes in adulthood. It is necessary to control obesity in children to prevent diabetes in adults.</p>

Objective To assess the cardiovascular structure and function in children with confirmed primary hypertension,and to explore the impact of hypertension and related risk factors on cardiovascular structure and function of children.Methods Parameters related to cardiac structure,vascular structure and function were measured in 213 hypertensive children,who were confirmed upon repeated measurements on separate occasions.A total of 197 healthy children were recruited as controls.Results 1) In hypertensive children,left ventricular end-diastolic diameter (LVEDd),left ventricular end-systolic diameter (LVESd),left ventricular mass (LVM),left ventricular mass index (LVMI),left ventricular posterior wall thickness (LVPT) and interventricular septal thickness (IVST) were all significantly higher than their counterparts (P<0.05).No statistical differences were found in carotid intima-media thickness (cIMT),relative wall thickness (RWT) and brachial ankle pulse wave velocity (ba-PWV).2) Compared with controls,LVEDd,LVESd,LVM,LVMI were all significantly higher in hypertensive children (P<0.05),regardless of age group or weight-status.No statistical differences were found in ccIMT and RWT,while ba-PWV was statistically higher in controls among children aged 6-12 years.3) Data from multiple linear regression analysis noticed that LVMI was associated with age,sex,BMI and hypertension while RWT was associated with age and BMI.Conclusion In children with primary hypertension,changes of vascular structure and function were not shown but left ventricular remodeling and early changes of function had been developed in children under 12 years old.
ABSTRACT
Objective To evaluate the prevalence of metabolic syndrome (MS) in Chinese children and adolescents to provide scientific basis for early prevention of MS in the related populations.Methods Studies on CNKI,Wanfangdata,VIP and PubMed databases on related prevalence of metabolic syndrome in Chinese children and adolescents between 2004-2014 were searched.Quality of literatures was evaluated according to the cross-sectional study standard in Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement.Stata 12.0 software was used to estimate the prevalence of MS,as well as on gender,weight and other factors to make subgroup analysis.According to funnel plot and Egger assess publication bias,sensitivity analysis performed by excluding the impact of any article was generated by the combined effect of the value of literature.Results This study included 19 papers from the literature (5 in English,14 in Chinese).According to International Diabetes Federation (IDF),National Cholesterol Education Program Ⅲ (NCEP Ⅲ) and The definition and prevention recommends of metabolic syndrome in Chinese children and adolescents (CHN2012),the prevalence rates of MS in Chinese children were seen as 1.8%,2.6% and 2.0%.According to IDF,the prevalence rates of MS appeared 2.9% in boys and 1.8% in girls,0.2% in children with normal weight,4.7% in overweight and 17.3% in obesity.Both the results from NCEP Ⅲ and CHN2012 showed that the prevalence rates of MS as boys>girls,obesity>overweight>normal weight.Conclusion Prevalence of MS in Chinese children and adolescents showed a general trend.Data under different standards showed different prevalence rates.Obesity appeared an important risk factor of MS,suggesting that in order to control obesity in children,attention should be paid to identifying and carrying out effective interventions on children under overweight or obesity.
ABSTRACT
Objective To observe the prevalence of hyperuricemia(HUA)among obese children,and to ex-plore the association between uric acid(UA)levels and cardiometabolic risk factors,acanthosis nigricans and non - al-cohol fatty liver disease(NAFLD). Methods By using representative sampling method,1 753 obese children aged 6 -17 years old from 18 schools in 3 districts of Beijing(Xicheng,Haidian,Miyun)were selected to participate in the clini-cal examinations,including anthropometric measurements(height,weight)and blood pressure. Serum biochemical pa-rameters were assessed,including fasting plasma glucose(FPG),total cholesterol(TC),triglyceride(TG),high - densi-ty lipoprotein cholesterol(HDL - C),low - density lipoprotein cholesterol(LDL - C)and UA. Acanthosis nigricans and B - model ultrasonography of the liver were conducted. Results The prevalence of hypertension,impaired fasting glu-cose,dyslipidemia,acanthosis nigricans,and NAFLD among these 1 753 obese children was 33. 6%(589 cases), 66. 5%(1 156 cases),54. 3%(943 cases),23. 3%(408 cases),and 17. 0%(298 cases),respectively. The preva-lence of HUA was 40. 70%(714 / 1 753 cases),with 50. 17%(581 / 1 158 cases)in boys and 22. 34%(133 / 595 ca-ses)in girls. There was a significant increase in body mass index,systolic blood pressure,diastolic blood pressure, FPG,TG and LDL - C with the increase of UA,but there was a decrease in HLD - C with the increase of UA(all P ﹤0. 05). In boys,the adjusted odds ratios( OR)and 95% CI of the highest quartile of UA for hypertension,impaired fasting glucose,dyslipidemia,acanthosis nigricans,and NAFLD were 1. 16(0. 77 - 1. 74),1. 34(0. 90 - 1. 99),1. 29 (0. 89 - 1. 87),1. 89(1. 17 - 3. 04),and 1. 71(1. 03 - 2. 84),respectively;in girls,the adjusted OR and 95% CI of the highest quartile of UA for hypertension,impaired fas-ting glucose,dyslipidemia,acanthosis nigricans,and NAFLD was 0. 70(0. 40 - 1. 24),0. 60(0. 40 - 1. 00),1. 69(1. 04 - 2. 70),1. 67(0. 80 - 3. 49),and 1. 33(0. 48 - 3. 66),re-spectively. Conclusions The prevalence of HUA is relatively high in obese children and there is a strong association between UA and some car-diovascular metabolic disorders,acanthosis nigricans and NAFLD.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the relationship between high-sensitivity C-reactive protein (hsCRP) and obesity/metabolic syndrome (MetS) related factors in children.</p><p><b>METHODS</b>403 children aged 10-14 and born in Beijing were involved in this study. Height, weight, waist circumference, fat mass percentage (Fat%), blood pressure (BP), hsCRP, triglyceride (TG), total cholesterol (TC), fasting plasma glucose (FPG), high and low density lipoprotein cholesterol (HDL-C, LDL-C) were observed among these children. hsCRP was transformed with base 10 logarithm (lgCRP). MetS was defined according to the International Diabetes Federation 2007 definition. Associations between MetS related components and hsCRP were tested using partial correlation analysis, analysis of covariance and linear regression models.</p><p><b>RESULTS</b>1) lgCRP was positively correlated with BMI, waist circumference, Fat%,BP, FPG, LDL-C and TC while negatively correlated with HDL-C. With BMI under control, the relationships disappeared, but LDL-C (r = 0.102). 2) The distributions of lgCRP showed obvious differences in all the metabolic indices, in most groups, respectively. With BMI under control, close relationships between lgCRP and high blood pressure/high TG disappeared and the relationship with MetS weakened. 3) Through linear regression models, factors as waist circumference, BMI, Fat% were the strongest factors related to hsCRP, followed by systolic BP, HDL-C, diastolic BP, TG and LDL-C. With BMI under control, the relationships disappeared, but LDL-C(β = 0.045).</p><p><b>CONCLUSION</b>hsCRP was correlated with child obesity, lipid metabolism and MetS. Waist circumference was the strongest factors related with hsCRP. Obesity was the strongest and the independent influencing factor of hsCRP.</p>

<p><b>OBJECTIVE</b>To analyze the trends on the prevalence rates of obesity and cardiometabolic among children and adolescents in Beijing, during 2004-2013.</p><p><b>METHODS</b>Data was collected from three cross-sectional studies among children and adolescents, aged 7-17 years old in Beijing. Two studies in 2004 and 2013 were conducted in general population, and one was among obese children in 2007. Data on anthropometric measurements including weight, height, and age was collected from all the subjects. The obese children from all three studies underwent a clinic examination that containing blood pressure, fasting plasma glucose, lipid profile (TC, TG, LDL-C, HDL-C), and acanthosis nigricans. Liver transaminases detection (ALT and AST) and liver ultrasound examination were performed in obese children from surveys in 2007 and 2013.</p><p><b>RESULTS</b>The prevalence of severe obesity increased from 1.86% in 2004 to 4.17% in 2013, with an annual increase rate as 0.26%. The proportion of severe obesity in obesity increased from 18.92% in 2004 to 25.15% in 2013. After adjusting for age and gender, the prevalence of IFG, hypertriglyceridemia and low HDL-C in both obese children and adolescents increased during 2004-2013 (all P < 0.05). The prevalence rates of hypertension, dyslipidemia, hypertriglyceridemia, and acanthosis nigricans in severe obese children were higher than those in moderate obesity. The proportion of children with 2 or more cardiometabolic risk factors in severe obese children was higher than in moderate obese children.</p><p><b>CONCLUSION</b>The prevalence rates of obesity and cardiometabolic risk factors among children and adolescents in Beijing showed an increase during 2004-2013.</p>

Objective To analyze the dynamic trends of physical development,constitutional fitness,and prevalence of obesity among Han children and adolescents in Ningxia aged 7-18 years from 1985 to 2010.Methods Data were collected from the National Survey on Students Constitution and Health in 1985,1991,1995,2000,2005 and 2010,respectively.Height,weight and chest circumference were used to evaluate physical development,vital capacity,50-meter running and vital capacity versus weight ratio for the evaluation of constitutional fitness.Results 1.Weight and chest circumference increased faster than height.The average annual increase of weight among the urban girls was significantly faster than those in rural areas.2.The tempo per year of vital capacity in both boys and girls decreased during 25 years,especially after 2005.The rural students had a faster tempo than those in the urban students,and the rate in boys was higher than those in girls.Vital capacity to weight ratio in boys decreased from 2005 much more than before,and had a decreasing trend in each age group except for a few groups in girls.There was a decrease in the mean time of 50-meter running in both boys and girls from 1985 to 2005,whereas the decrease became slow during 1995-2005.The prolonged trend in 50-meter-run time existed during 2005-2010.The average prolonged speeds per decade in boys and urban students was higher than that in girls and rural areas.3.From 1985 to 2010 year,the increasing prevalence of overweight and obesity among boys and girls was 15.0%,25.0% and 28.1%,12.4%,respectively.The average increasing rate was much higher in the obese than in the over-weighted children,and there were more in boys than in girls.There was a similar positive trend of increasing prevalence of overweight and obesity with the increased gross domestic product.Conclusions The physical growth and development among students in Ningxia increased rapidly,along with the descending trend of average annual rate of physical fitness as well as the rising trend of prevalence obesity.Some measures should be taken by the government to tackle with the situation,and the healthy intervention should be applied to the high risk population.
ABSTRACT
Objective To explore the relationship between high-sensitivity C-reactive protein (hsCRP)and obesity/metabolic syndrome(MetS)related factors in children. Methods 403 children aged 10-14 and born in Beijing were involved in this study. Height,weight,waist circumference,fat mass percentage(Fat%),blood pressure(BP),hsCRP,triglyceride(TG),total cholesterol(TC), fasting plasma glucose(FPG),high and low density lipoprotein cholesterol(HDL-C,LDL-C)were observed among these children. hsCRP was transformed with base 10 logarithm(lgCRP). MetS was defined according to the International Diabetes Federation 2007 definition. Associations between MetS related components and hsCRP were tested using partial correlation analysis,analysis of covariance and linear regression models. Results 1) lgCRP was positively correlated with BMI,waist circumference,Fat%,BP,FPG,LDL-C and TC while negatively correlated with HDL-C. With BMI under control,the relationships disappeared,but LDL-C(r=0.102). 2)The distributions of lgCRP showed obvious differences in all the metabolic indices,in most groups,respectively. With BMI under control,close relationships between lgCRP and high blood pressure/high TG disappeared and the relationship with MetS weakened. 3) Through linear regression models, factors as waist circumference,BMI,Fat% were the strongest factors related to hsCRP,followed by systolic BP, HDL-C,diastolic BP,TG and LDL-C. With BMI under control,the relationships disappeared,but LDL-C (β=0.045). Conclusion hsCRP was correlated with child obesity,lipid metabolism and MetS. Waist circumference was the strongest factors related with hsCRP. Obesity was the strongest and the independent influencing factor of hsCRP.
