Growth status of Jordanian schoolchildren in military-funded schools

OBJECTIVE: To study the growth status of Jordanian boys and girls in comparison with the Centers for Disease Control (CDC) growth charts. DESIGN: Cross-sectional study. SUBJECTS AND DATA COLLECTION: A total of 5826 boys and 1414 girls, aged 6.5-17.5 y, were included in the study. Height and weight were measured. Body mass index (BMI) was calculated as weight (kg) divided by the square of the height (m). Socioeconomic data were collected using a structured questionnaire. RESULTS: The height-for-age values fluctuated between the 5th and 10th percentiles of the CDC for both sexes, and then after the age of 8.5 and 14.5 y for boys and girls, respectively, values were just above the 10th percentile. The body weight-for-age values were just above the 25th percentile for boys and fluctuated between the 25th and 50th percentiles for girls; then after the age of 14.5 and 12.5 y for boy and girls, respectively, values fluctuated between the 25th and 50th percentiles for boys and just above the 50th percentile for girls of the CDC values. BMI values for boys were just above the 50th percentile of the CDC and for girls values fluctuated between the 50th and 75th percentiles until the age of 13.5, then values matched the 75th percentile of the CDC. CONCLUSION: The height of Jordanian children ranges from the 5th to the 10th percentile of the CDC reference values during schools years. Girls have a tendency toward obesity after puberty.     

Height and weight of Southeast Asian preschool children in Northern California.

Anthropometric data were obtained from 526 Southeast Asian preschool children during 1980-84. Length of time in the United States averaged 21.8 months. Mean weights and heights were substantially below the National Center for Health Statistics (NCHS) 50th percentile. Although 39 per cent of children were below the 5th percentile of height for age, only 7 per cent were below the 5th percentile of weight for height. Rates of weight and height gain were similar to reference values, indicating adequate growth after arrival in the US.     

Most Short Children with Cystic Fibrosis Do Not Catch Up by Adulthood

Poor linear growth is common in children with cystic fibrosis (CF) and predicts pulmonary status and mortality. Growth impairment develops in infancy, prior to pulmonary decline and despite aggressive nutritional measures. We hypothesized that growth restriction during early childhood in CF is associated with reduced adult height. We used the Cystic Fibrosis Foundation (CFF) patient registry to identify CF adults between 2011 and 2015 (ages 18–19 y, n = 3655) and had height for age (HFA) records between ages 2 and 4 y. We found that only 26% CF adults were ≥median HFA and 25% were <10th percentile. Between 2 and 4 years, those with height < 10th percentile had increased odds of being <10th percentile in adulthood compared to children ≥ 10th percentile (OR = 7.7). Of HFA measured between the 10th and 25th percentiles at ages 2–4, 58% were <25th percentile as adults. Only 13% between the 10th and 25th percentile HFA at age 2–4 years were >50th percentile as adults. Maximum height between ages 2 and 4 highly correlated with adult height. These results demonstrate that low early childhood CF height correlates with height in adulthood. Since linear growth correlates with lung growth, identifying both risk factors and interventions for growth failure (nutritional support, confounders of clinical care, and potential endocrine involvement) could lead to improved overall health.

Body mass index cutoffs for underweight, overweight, and obesity in South Korean schoolgirls

OBJECTIVES: To establish BMI percentiles and cutoffs for underweight, overweight, and obesity in South Korean schoolgirls. RESEARCH METHODS AND PROCEDURES: A total of 1229 South Korean schoolgirls aged 8 to 18 years were randomly selected to complete a self-administered questionnaire. BMI charts and cutoffs were constructed after analyzing data from 1107 subjects. Percentile curves were established by the modified LMS method. RESULTS: The percentiles for underweight, overweight, and obesity corresponding to BMI of 18.5, 23.0, and 25.0 kg/m2 at age 18 were the 13.0th percentile, the 77.8th percentile, and the 91.2nd percentile, respectively. The corresponding prevalences of underweight, overweight, and obesity were 12.1, 12.5, and 9.8%, respectively. DISCUSSION: We established for the first time, to our knowledge, new BMI cutoffs for ages 8 to 18 that corresponded to BMIs of 18.5, 23.0, and 25.0 kg/m2 for Asian adults designated by the International Obesity Task Force. These newly established BMI cutoffs might help to estimate the prevalence of overweight and obesity in Asian children.     

Weight status in childhood as a predictor of becoming overweight or hypertensive in early adulthood

OBJECTIVE: To assess the extent to which weight status in childhood or adolescence predicts becoming overweight or hypertensive by young adulthood. RESEARCH METHODS AND PROCEDURES: We conducted a prospective study of 314 children, who were 8 to 15 years old at baseline, and were followed up 8 to 12 years later. Weight, height, and blood pressure were measured by trained research staff. Incident overweight was defined as BMI>or=25 kg/m2 among participants who had not been overweight as children. RESULTS: More male subjects (48.3%) than female subjects (23.5%) became overweight or obese between their first childhood visit and the young adult follow-up (p<0.001). Being in the upper one half of the normal weight range (i.e., BMI between the 50th and 84th percentiles for age and gender in childhood) was a good predictor of becoming overweight as a young adult. Compared with children with a BMI<50th percentile, girls and boys between the 50th and 74th percentiles of BMI were approximately 5 times more likely [boys, odds ratio (OR)=5.3, p=0.002; girls, OR=4.8, p=0.07] and those with a BMI between the 75th and 84th percentiles were up to 20 times more likely (boys, OR=4.3, p=0.02; girls, OR=20.2, p=0.001) to become overweight. The incidence of high blood pressure was greater among the male subjects (12.3% vs. 1.9%). Compared with boys who had childhood BMI below the 75th percentile, boys between the 75th and 85th percentiles of BMI as children were four times more likely (OR=3.6) and those at above the 85th percentile were five times more likely (OR=5.1) to become hypertensive. DISCUSSION: High normal weight status in childhood predicted becoming overweight or obese as an adult. Also, among the boys, elevated BMI in childhood predicted risk of hypertension in young adulthood.     

Reference growth curves for cypriot children 6 to 17 years of age.

OBJECTIVE: The purpose of the study was to present smoothed percentiles for body weight and height, waist circumference, and body mass index (BMI) in Cypriot children and to compare their BMI 85th and 95th percentiles with those of children in other countries. RESEARCH METHODS AND PROCEDURES: The study was a cross-sectional study, including a representative sample of 2472 healthy children (49.1% boys) in Cyprus ages 6 to 17 years, who were evaluated during the 1999-2000 school year. Body weight and height and waist circumference were measured using standard procedures. BMI was calculated as weight in kilograms per height in square meters. Smoothed, sex-specific percentiles for these variables were calculated using polynomial regression models. Crude weight, height, waist, and BMI percentile values are presented in sex-specific tables and smoothed percentile curves are presented in charts. The 85th and 95th percentiles for BMI were compared with measurements from other countries, because of the concern of the upper limits of BMI in respect to the evaluation of obesity. RESULTS: The 85th and 95th BMI percentile values are higher in Cypriot boys than in Swedish and Iranian boys through all ages and in girls ages 6 to 15 years, whereas after the age of 15 years, both Swedish and Iranian girls' percentiles are equalized with their Cypriot peers. DISCUSSION: Weight, height, waist circumference, and BMI values and charts are presented for the first time for Cypriot children and adolescents. Much concern should be addressed to the observation that for the majority of the Cypriot sample, the upper BMI limits are higher than the peers of developing and developed countries.     

Anthropometric Characteristics of Pakistani School Children Living in Bahrain

Background This survey was designed to study the gender difference in physical growth of 1113 Pakistani children (646 male and 467 female) living in Bahrain and to compare growth with their Bahraini and Pakistani counterparts. Methods Measurements of height, weight, mid-arm circumference, biceps, triceps, subscapular and suprailiac skinfold thickness were carried out using the standard methods, and the median values for height and weight were plotted against the National Center for Health Statistics (NCHS) standard charts. Results The median weight of the boys was below the 25th percentile rising slightly above the 25th percentile at 12 years. The median height was also below the 25th percentile touching the 25th percentile only between 10–12 and 17 years. In girls, the median weight touched the 50th percentile at 15 years, followed by a fall to the 5th percentile between 16 and 17 years of age while the median height touched the 5th percentile at 17 years of age. The median body mass index (BMI) values were above the 50th percentile between 13 and 15 years in boys, and below the 50th percentile at all ages in girls. The median triceps skinfold thickness in boys was above the 50th percentile between 10–15 and 17 years in boys and in girls it was mostly below the 50th percentile rising above 50th percentile at 14, 15 and 17 years of age. Conclusion The height and weight of the study group was similar to that of children residing in Pakistan for both the genders, but lower than their Bahraini counterparts for most age groups compared. Furthermore, Pakistani boys residing in Bahrain were taller after 14 years of age and heavier after 16 years of age compared to their female counterparts.     

Mexican anthropometric percentiles for ages 10-18

OBJECTIVE: To elaborate Mexican growth charts based on international methodology. DESIGN: Data were obtained from the Mexican National Health Survey. The survey was stratified and probabilistic representative of all the country. SETTING: Nationwide open population living in urban and rural areas. SUBJECTS: Boys (8545) and girls (9983) from 10 to 18 years participating in the survey. METHODS: Age, weight and height were recorded. Empirical percentiles were calculated and smoothed. Smoothed curves were approximated using least-mean square estimation. RESULTS: Tables and figures for percentile values of weight, height and body mass index (BMI) for age, as well as percentile values of weight and BMI for height for both genders are presented. Regarding 50th BMI for age percentiles, Mexicans had higher levels than the Americans in the Centers for Disease Control and Prevention growth charts; Mexicans were lower but had similar weights than the Americans. Owing to the high BMI, the percentile corresponding to an overweight level (25 kg/m(2)) at 18 years was 74.5 in boys and 72.5 in girls, whereas obesity level (30 kg/m(2)) at 18 years was 97.3 and 97.4 in boys and girls, respectively. CONCLUSIONS: The present growth charts are snapshots of a Mexican population. Because of the high median BMI compared to US and World Health Organization standards, we must be cautious in establishing an upper normal cutoff for clinical normality, not merely selecting the 85th and 95th percentiles as equivalents of overweight and obesity, respectively. Therefore, we proposed percentiles 74.5 in boys and 72.5 in girls as the action points of overweight as they are the percentiles corresponding to BMI 25 kg/m(2) at 18 years. SPONSORSHIP: The survey was supported by the Mexican Minister of Health. Statistical analyses were sponsored by Dr Del-Rio-Navarro.     

Comparison of growth status of patients with cystic fibrosis between the United States and Canada

BACKGROUND: Differences in growth status of patients with cystic fibrosis (CF) between the United States and Canada were reported in the 1980s based on analysis of data from 2 regional CF centers. OBJECTIVE: We evaluated the current growth status of the entire CF population in the United States and Canada in view of recent advances in the treatment of CF. DESIGN: Growth data from the 1992-1994 CF Patient Registries were analyzed. RESULTS: Mean height and weight were at approximately the 30th percentile for children with CF in the United States. Mean height and weight were 4-5 percentiles higher in children with CF in Canada than in those in the United States (P < 0.01), but percentages of ideal weight (104%) were similar in both populations. In adults with CF, mean height was similar at the 37th percentile; however, weight (26th compared with the 21st percentiles) and percentage of ideal weight (93% compared with 90%) were significantly higher in Canada than in the United States. Differences related to sex and age were similar in both countries for all indexes, which showed a high prevalence of underweight in infants and in older patients, but little sex discrepancy. CONCLUSION: We observed substantially smaller differences in the growth indexes of CF patients between the United States and Canada compared with results from the 1980s. These findings reflect significant improvements in the nutritional status of US patients in recent years. However, caution is required in the direct comparison of mean percentiles from reports using different growth standards because there are systematic differences in growth standards, which affect, in particular, the comparison of growth in males and females.     

Comparison of the use of body mass index percentiles and percentage of ideal body weight to screen for malnutrition in children with cystic fibrosis

BACKGROUND: The Cystic Fibrosis Foundation (CFF) recommends using the percentage of ideal body weight (%IBW(CFF)) and body mass index percentiles (BMIp) to assess weight-for-height status and to screen for malnutrition. OBJECTIVE: The objective was to examine the agreement and discrepancy between the use of %IBW(CFF) and BMIp for screening malnutrition. DESIGN: Data from 13 021 children reported to the 2000 CFF Patient Registry were analyzed. RESULTS: In children of average stature (ie, height-for-age between the 25th and 75th percentiles) and aged <10 y, %IBW(CFF) corresponded closely to BMIp, and the prevalence of underweight estimated by %IBW(CFF) < 90% was similar to that by BMIp < 15th percentile. However, in children with short stature (ie, height-for-age < 25th percentile), %IBW(CFF) reflected significantly better weight-for-height status than did the BMIp, whereas the opposite trend was observed in children with tall stature (ie, height-for-age > 75th percentile). Such discrepancies averaged 8-12 percentage points when BMIp was reexpressed to the same unit and scale as %IBW(CFF). Consequently, the prevalence of underweight estimated by %IBW(CFF) < 90% was significantly lower (7.3%) than that estimated by BMIp < 15th percentile (25.7%) in children with short stature, whereas the opposite trend was found in children with tall stature (47.7% and 14.4%, respectively). Additional analyses showed that BMIp was more sensitive to, and had stronger associations with, the percentage of predicted forced expiratory volume in 1 s. CONCLUSION: Compared with BMIp, %IBW(CFF) underestimated the severity of malnutrition in children with short stature and overestimated the severity of malnutrition in children with tall stature.     

Anthropometry of Mexican-American migrant children in northern California

Anthropometric data were obtained from 209 Mexican-American migrant children, aged 0 to 7 yr, in the Sacramento Valley of California. Hematocrit was measured for 170 children. Only 13 children (7.6%) had hematocrits below acceptable levels. Weight-for-age, height-for-age, and weight-for-height growth percentiles approximated the National Center for Health Statistics standards. Only 15% of the children were at or below the 10th percentile of height-for-age, and only 7% were above the 95th percentile of weight-for-height, in contrast to earlier studies of Mexican-American children. The mean percentile of weight-for-height increased significantly with age, while height-for-age decreased. The rate of growth in weight and height accelerated during their summer residence in the US, indicating that the adequate growth status of these children may be related to improved conditions for growth while in the US.     

Weight-for-stature compared with body mass index-for-age growth charts for the United States from the Centers for Disease Control and Prevention

BACKGROUND: The 2000 Centers for Disease Control and Prevention growth charts for the United States include population reference data for body mass index (BMI)-for-age (ages 2-19 y) and weight-for-stature (from 77 to 121 cm). For younger children, either set of reference data could be used. OBJECTIVE: The objective of this study was to compare BMI-for-age with weight-for-stature. DESIGN: We used data for 4348 children (aged 2-5 y) from the third National Health and Nutrition Examination Survey. Weight-for-stature and BMI-for-age percentiles were calculated for each child. The 10th and 85th percentiles of weight-for-stature at selected ages were also reexpressed as BMI-for-age percentiles. RESULTS: More than 63% of children had lower weight-for-stature than BMI-for-age percentiles. Children were more likely to be classified as < or = 10th percentile by weight-for-stature than by BMI-for-age, but less likely to be classified as > or = 85th percentile. Differences in classification by the 2 measures varied with age and stature and were greater for shorter children. The 10th and 85th percentiles of weight-for-stature corresponded to BMI-for-age percentiles from the 3rd to the 21st percentile and from the 74th to the 92nd percentile, respectively, depending on age and stature. CONCLUSIONS: Weight-for-stature is easier to use than BMI-for-age. However, BMI-for-age captures changes in the weight-height relation with age and can be used continuously up to the age of 20 y. BMI-for-age is recommended in most situations. BMI-for-age and weight-for-stature will not give identical results and are not interchangeable.     

Growth Status and Related Medical Conditions Among Refugee Children in Massachusetts, 1995–1998

OBJECTIVES: This study analyzed growth and identified related medical conditions among refugee children in Massachusetts. METHODS: Between July 1995 and June 1998, 1825 refugee children were screened. Variables included positive tuberculin (purified protein derivative; PPD) test; dental abnormalities; pathogenic parasites; weight-for-age, height-for-age, and weight-for-height z scores; and body mass index greater than the 84th percentile. RESULTS: Of all the children, 21% had parasites, 62% had caries, and 25% had a positive PPD reaction. Twelve percent overall and 28% younger than 2 years had anemia. Eight percent had height-for-age z scores less than -2, and 6% had weight-for-age z scores greater than +2. Of those aged 1 to 9 years, 7% had weight-for-height z scores greater than +2. Weight-for-height z scores less than -2 were concentrated among Africans and East Asians (both 8%). Height-for-age z scores less than -2 were seen among African (13%), Near Eastern (19%), and East Asian (30%) children. Weight-for-height z scores greater than +2 and body mass index greater than the 84th percentile were concentrated among children from the former Yugoslavia (8% and 15%) and the former Soviet Union (8% and 14%). CONCLUSIONS: Recently arrived refugee children have significant growth abnormalities. European refugees were overweight; those from developing countries had growth retardation.     

Selected body composition and growth measures of junior elite gymnasts

Selected body composition measures of female junior elite gymnasts (n = 146) were evaluated cross-sectionally (ie, we observed a younger and an older group at one point in time, not the same individuals over time). For certain comparisons, the gymnasts were grouped into a younger group (7- to 10-year-olds) and an older group (11- to 14-year-olds). Gymnasts were in the 50th percentile for weight:height ratio, regardless of age. However, weight:age and height:age percentiles progressively dropped from the 48th to the 20th as age increased. Body fat percentage did not differ significantly between age groups. Triceps and subscapular skinfolds were 63% and 56%, respectively, of the age-related standard for the younger group and 52% and 39%, respectively, of the age-related standard for the older group. Arm muscle circumference and calculated arm muscle area of the gymnasts were in about the 75th percentile, regardless of age grouping. In general, as they grew older, gymnasts became progressively smaller in weight and height for age but were highly muscled for size. The steady age-related drop in height:age and weight:age percentile may be attributable to nutritional deficits, a sport-specific selection favoring retention of small but powerful gymnasts, or a combination of these factors. We recommend that young gymnasts be carefully observed longitudinally by trained nutrition professionals to ensure that inadequate nutrient intake is not a contributing factor to poor growth or health.

Nutritional status of Southeast Asian refugee children.

Since 1975 nearly 300,000 Indochinese refugees have been relocated in the United States. The Nutrition Division, Centers for Disease Control. Atlanta, surveyed the medical records of four west coast clinics to obtain nutrition-related data on 821 Southeast Asian refugee children under six years of age, arriving between July 1979 and June 1989. Hemoglobin, hematocrit, and anthropometric data were compared to those of a comparison group of Southeast Asian children screened prior to 1979 and to a National Health Examination Survey reference population. The newly-arrived refugee group was found to be highly anemic and stunted relative to the comparison group. Although stunted, the study group did not appear greatly wasted.     

A nutritional status study on under-privileged Mid-Day-Meal program beneficiaries of India

The nutritional status of under-privileged Mid-Day-Meal (MDM) Program beneficiaries and the contribution of MDM to their homelevel nutrition intake was investigated. The 50th percentile of weight, height and arm circumference of subjects corresponded with only the 5th percentile of Indian national norms. By Waterlow's classification about one-third were ‘stunted’. ‘Wasting’ afflicted more 10–15 year olds than 5–9 year olds. Anemia (Hb<11g/dl) was present in 73% boys and 67% girls. Eleven percent boys and 4% girls were classed as ‘active cases of xerophthalmia’ (night-blindness with conjuctival lesions). Parasitic infestation was detected in 44% boys and 35% girls. Only 12% consumed MDM on-site, the rest shared it with siblings. It was consumed less by the older (Std V–VII) than younger (Std I–IV) children and it also contributed less calories, protein, iron and retinol (as percent of RDA) to the older child's intake. The home diet of subjects provided less than 25% RDA of retinol for 67% boys and 72% girls: the deficit being more prevalent in 10–15 than 5–9 year olds. Iron and calorie intake was also inadequate. MDM increased retinol intake marginally to about half the RDA for younger, and to only one-third the RDA for older children. Iron intake was brought upto 75% RDA, except in 10–15 year old girls (48% RDA). Thus, the older MDM beneficiaries, who have a poorer nutritional status and receive less MDM, need a higher allocation of MDM ration.     

中国7～18岁学龄儿童青少年腰围界值点研究

目的 根据儿童不同腰围水平罹患心血管疾病的危险,研究中同学龄儿童青少年腰围的适宜界值点.方法 利用受试者工作特征曲线(ROC)法分析从全国汇总的65 898名7～18岁学龄儿童青少年腰围及其相关代谢指征数据,探索预测心血管疾病的腰围最佳界值点.结果 儿童青少年腰围值小于第75百分位数(P75)时,收缩压、舒张压、血糖、总胆固醇、甘油三酯和低密度脂蛋白胆固醇水平以及血压升高率、血糖升高率、血脂异常率随腰围变化趋势不明显,当腰围大于P75后,上述指标逐渐增加,从P90开始,增加趋势明显,高密度脂蛋白胆固醇的变化趋势相反.ROC曲线结果表明,预测血压增加的腰围最佳界值点为P75;预测至少两项心血管疾病危险因素聚集的最佳界值点为P90.与腰围低于P75,的儿童青少年相比,在腰围处于P75～P90者中至少聚集两项心血管疾病危险因素的比例增加了1倍,腰围大于P90者中该比例则增加了5倍.按体重指数分类标准分层后,儿童青少年血压升高率仍然随腰围增加而显著增加.结论 建议将中国儿童青少年腰围的年龄别性别P7,和P90作为儿童青少年心血管病危险开始增加和明显增加的界值点.
