Are age references for waist circumference,hip circumference and waist-hip ratio in Dutch children useful in clinical practice?

The aim of this study was to present age references for waist circumference (WC), hip circumference (HC), and waist/hip ratio (WHR) in Dutch children. Cross-sectional data were obtained from 14,500 children of Dutch origin in the age range 0–21 years. National references were constructed with the LMS method. This method summarises the distribution by three smooth curves representing skewness (L curve), the median (M curve), and coefficient of variation (S curve). The correlations between body mass index-standard deviation score (BMI-SDS), the circumferences and their ratio, and demographic variables were assessed by (multiple) regression analysis for three age groups: 0-<5 years (1), 5-<12.5 years (2), and 12.5-<21 years (3). A cut-off for clinical use was suggested based on the International Obesity Task Force criteria for BMI. Mean WC and HC values increased with age. Mean WC was slightly higher in boys than in girls, and this difference was statistically significant from 11 years of age onwards. In contrast, HC was significantly higher in girls than in boys from 9 years onwards. The correlation between WC-SDS and BMI-SDS ( r =0.73, P <0.01) and between HC and BMI-SDS ( r =0.67, P <0.01) increased with age. With regard to WHR-SDS, a low correlation was found for 12.5–20 years of age ( r =0.2, P <0.01). WC-SDS correlated positively with height SDS ( r =0.35, P <0.01). Conclusion:Waist circumferences can be used to screen for increased abdominal fat mass in children, whereby a cut-off point of 1.3 standard deviation score seems most suitable.     

First reference curves of waist circumference for German children in comparison to international values: the PEP Family Heart Study

Background  Waist circumference (WC) is a sensitive marker for abdominal obesity in the pediatric age group. However, WC is influenced by age, sex, ethnicity and body mass index (BMI), causing difficulties in the selection of the most appropriate cut-off value. Considering the lack of reference values in Germany, we developed age- and gender-specific WC smoothed reference curves in German children, and compared them with reference curves obtained from different countries. Methods  A representative sample of 3531 German children (1788 boys, 1743 girls) aged 3–11 years participating in the Prevention Education Program (PEP) Family Heart Study was studied. WC was measured according to the recommendations of the World Health Organization, then age- and sex-specific WC reference curves were constructed and smoothed using the LMS method and SPSS 14.0 for statistical analysis. Results  WC increased with age in both boys and girls. Boys had higher values of WC than girls at every age and percentile level. 4.1% of the boys and 2.8% of the girls had WC values >97th percentile as compared to 6.3% of the boys and 4.9% of the girls with >97th percentile of BMI (severe obesity). 3.1% of the boys and 2% of the girls had both risk factors. Because 85.3% of the boys and 87.3% of the girls with WC<90th percentile had normal weight, this cut-off point might be appropriate for defining high WC. Conclusions  These first WC reference curves of German children can be added to the existing international curves for children; comparison of different populations demonstrated that the German values are in the middle range of the curves obtained in different countries. Our findings about significant differences between the reference curves obtained in various regions emphasize the necessity of developing population-specific percentiles, and to use them in clinical and epidemiological studies among children.

Anthropometric correlates of lipoprotein profile and blood pressure in high BMI African American children

Objective: To explore the association of anthropometric indices with lipoprotein profile and blood pressure as risk factors of cardiovascular disease, in African American (AA) children. Methods: A cross‐sectional analysis was carried out on children aged 9–13 years with BMI >85th percentile. Height, weight, waist and hip circumferences, % body fat and blood pressure [systolic (sBP) and diastolic (dBP)] were measured. Fasting plasma levels of triglycerides (TG), total cholesterol (TC), high‐density lipoprotein cholesterol (HDL‐C), low‐density lipoprotein cholesterol (LDL‐C), intermediate density lipoprotein cholesterol (IDL‐C) and very low‐density lipoprotein cholesterol (VLDL‐C) were analysed. Results: After accounting for age, gender and pubertal status of the child, multiple linear regression models showed that waist circumference and BMIz were strong predictors for lipoprotein variables. In independent analysis, waist circumference and BMI z‐scores were found to be interdependently associated with TG, LDL‐C:HDL‐C ratio, VLDL‐C and sBPz. However, for HDL‐C, TG:HDL‐C ratio and dBPz, waist circumference was independently and more strongly associated with these risk factors than BMI. Conclusion: Waist circumference was a stronger predictor for lipoprotein variables and blood pressure in high BMI AA children than other anthropometric indices, and may be adequate as a screening test to identify children who are at increased risk for cardiovascular disease.     

Study on the reference values of serum lipids in children aged 3–18 years old in Beijing,China

Background: The present study was designed to explore the reference values of serum lipids in children in Beijing. Methods: A total of 1071 healthy children from Beijing between 3 and 18 years of age were enrolled and divided into four groups: A, 3–5‐year‐old group; B, 6–9‐year‐old group; C, 10–14‐year‐old group; and D, 15–18‐year‐old group. Blood samples were obtained from the cubital veins of the participants under a fasting condition. A Hitachi 7600 Automatic Biochemistry Analyzer was used to determine the serum levels. The cut‐off points of reference values were the 75th and 95th percentiles for total cholesterol (TC), triglyceride (TG), and low‐density lipoprotein cholesterol (LDL‐C) while the 25th and 5th percentiles were used for high‐density lipoprotein cholesterol (HDL‐C) concentrations. Results: The highest 95th percentiles of TC among the four groups were 5.34 mmol/L for boys and 5.11 mmol/L for girls. Compared with those of boys, female TG levels were obviously higher in the 10–14‐year‐old group (P < 0.05) and HDL‐C levels were significantly higher in the 15–18‐year‐old group (P < 0.05). The serum TC, HDL‐C, and LDL‐C all peaked during the 6–9‐year‐old period and then declined during the adolescent stage. Also, the serum TG continuously increased with a relative plateau during the 6–14‐year‐old period. Obese and overweight children had higher TG and LDL‐C levels but lower HDL‐C levels. Conclusion: This study showed a picture of the serum lipids distribution in Chinese children and found that their TC levels were lower than those of children in Japan, Iran, and France, but were higher than those of Italian children.     

First reference curves of waist and hip circumferences in an Asian population of youths: CASPIAN study

The Objective of the present study is to develop the first age- and gender-specific reference curves for waist and hip circumferences in an Asian population of youths. This cross-sectional population survey was conducted in 2003-04 on a nationally representative sample of 21111 school-students living in urban (84.6%) and rural (15.4%) areas of 23 provinces in Iran. After anthropometric measurements, smoothed reference curves for waist and hip circumference (WC, HiC) and waist-to-hip ratio (WHR) were developed by the LMS method. In both genders, WC and HiC percentile values increased with age. For girls, the 50th to 95th percentile curves for WC had a sharp increase between 8 and 13 years and 11-15 years, respectively, and began to plateau after this age, whereas for boys, these curves had a persistent and less sharp increase with age, until the age of 18 years. The WHR curves of girls decreased with age until 15 years and began to plateau thereafter, whereas for boys the 25th to 95th curves had a plateau pattern. Comparison of the current reference curves with the British ones showed that in boys, the 5th and 50th percentile curves were similar in both studies, but the 95th percentile curve of our study was higher than the British curves. For girls, the 5th percentile curves of both studies were similar, but the 50th and 95th percentile curves of our study were higher than the British ones. These curves represent the first childhood WC, HiC and WHR reference curves obtained in Asia. These curves can provide baseline data for analysis of time trends, as well as for international comparisons.     

Waist circumference in relation to body perception reported by Finnish adolescent girls and their mothers

Aim: To study how waist circumference (WC) relates to body perception in adolescent girls and to maternal perception of the girl's body size.
Methods: Three hundred and four girls, 11–18 years, were measured for height, weight and WC. 294 girls provided self-report data on weight, height and body image before anthropometric measurements. Paired data from 237 girls and mothers on perception of the girls' body size were collected.
Results: In girls, self-reported weight indicated awareness of actual body size. The girls' body perception showed an overestimation of body size relative to international reference values for body mass index (BMI) (p < 0.05), but not for WC. Girls' body perception exceeded that of their mothers (p < 0.05). Maternal perception agreed better than the girls' perception with international reference values for BMI (p < 0.05). No significant difference between mothers and girls were found concerning agreement of body perception with international reference values for WC.
Conclusion: WC rather than BMI agrees with perception of body size, possibly due to its relation to abdominal fat at different ages. For effective prevention and treatment programmes for weight-related health problems among adolescent girls, we recommend measuring WC to diminish the discrepancy between measured and perceived body size.     

肥胖儿童血浆脂联素与肿瘤坏死因子-α的变化及意义

目的儿童肥胖症与血浆脂联素（ADPN）和肿瘤坏死因子-α（TNF-α）水平的变化密切相关。该文通过分析肥胖儿童血浆ADPN和TNF-α的变化及其相互关系,探讨儿童肥胖症的发病原因,为儿童肥胖症的预防提供科学依据。方法265名儿童随机分为肥胖组（147人）和正常对照组（118人）,分别测定腰围（WC）,臀围,腰臀比（WHR）,体脂百分比（%BF）,收缩压（SBP）,舒张压（DBP）,甘油三酯（TG）,总胆固醇（TC）,高密度脂蛋白胆固醇（HDL-C）,低密度脂蛋白胆固醇（LDL-C）,空腹血糖（FBG）,空腹胰岛素（FINS）,ADPN,TNF-α,计算稳态模型胰岛素抵抗指数（HOMA-IR）,并分析ADPN,TNF-α与体质量指标、糖脂代谢指标及二者的相关关系。结果①肥胖组儿童ADPN水平低于正常组儿童（P<0.05）,且与TNF-α,BMI,WHR,HOMA-IR,%BF,FINS,SBP,TG呈显著负相关（均P<0.05）;②肥胖组儿童TNF-α水平高于正常组儿童(P<0.01),且与BMI,WHR,%BF,FINS,HOMA-IR,TG,SBP呈显著正相关（P<0.01）,与HDL（P<0.05）呈负相关;③多元逐步回归分析显示ADPN,BMI和TNF-α是影响BF%的主要因素（R2=0.926）,且ADPN和TNF-α的交互作用有统计学意义。结论 肥胖儿童ADPN水平显著下降、TNF-α水平显著升高,且均是影响儿童体脂的主要因素。ADPN与TNF-α的交互作用提示二者在机体内可相互影响,共同参与儿童肥胖的形成。［中国当代儿科杂志,2009,11（1）：47-50］     

Predictive value of body mass index and waist circumference for metabolic syndrome in 6-12-year-olds

Aim: To determine the predictive value of body mass index (BMI) and waist circumference (WC) and their optimal cut‐off points for metabolic syndrome (MetS), and also the incidence of MetS. Methods: This study included 888 children, aged 6–12 years, who were followed for a mean of 6.6 years. BMI, WC and their optimal cut‐off points to predict MetS were investigated. Results: The cumulative incidence of MetS was 10.7%. The adjusted ORs for age, sex and family history to predict MetS for BMI and WC z‐scores were 2.6 (95% CI, 2.0–3.5) and 2.6 (95% CI, 1.9–3.5), respectively. In their correspondent models, area under the receiver operating characteristic (ROC) curve was 0.73 (95% CI, 0.68–0.79) for BMI z‐scores and 0.72 (95% CI, 0.67–0.78) for WC z‐scores with no statistically significant difference. The optimal cut‐off values for BMI were 16.5 kg/m² for boys and 16.3 kg/m² for girls and those for WC were 57.5 cm for boys and 56.5 cm for girls. Conclusions: Our findings suggest that both BMI and WC have the same power to predict MetS and also children with higher BMI or WC are more susceptible to MetS. Moreover, a high incidence of MetS in children highlights the importance of interventional strategies during early childhood.
