Longitudinal study on catch-up growth in preterm infants with small for gestational age at corrected ages 0-24 months / 中国当代儿科杂志

OBJECTIVES@#To understand the growth and development status and differences between small for gestational age (SGA) and appropriate for gestational age (AGA) preterm infants during corrected ages 0-24 months, and to provide a basis for early health interventions for preterm infants.@*METHODS@#A retrospective study was conducted, selecting 824 preterm infants who received regular health care at the Guangzhou Women and Children's Medical Center from July 2019 to July 2022, including 144 SGA and 680 AGA infants. The growth data of SGA and AGA groups at birth and corrected ages 0-24 months were analyzed and compared.@*RESULTS@#The SGA group had significantly lower weight and length than the AGA group at corrected ages 0-18 months (P<0.05), while there were no significant differences between the two groups at corrected age 24 months (P>0.05). At corrected age 24 months, 85% (34/40) of SGA and 79% (74/94) of AGA preterm infants achieved catch-up growth. Stratified analysis by gestational age showed that there were significant differences in weight and length at corrected ages 0-9 months between the SGA subgroup with gestational age <34 weeks and the AGA subgroups with gestational age <34 weeks and 34 weeks (P<0.05). In addition, the weight and length of the SGA subgroup with gestational age 34 weeks showed significant differences compared to the AGA subgroups with gestational age <34 weeks and 34 weeks at corrected ages 0-18 months and corrected ages 0-12 months, respectively (P<0.05). Catch-up growth for SGA infants with gestational age <34 weeks and 34 weeks mainly occurred at corrected ages 0-12 months and corrected ages 0-18 months, respectively.@*CONCLUSIONS@#SGA infants exhibit delayed early-life physical growth compared to AGA infants, but can achieve a higher proportion of catch-up growth by corrected age 24 months than AGA infants. Catch-up growth can be achieved earlier in SGA infants with a gestational age of <34 weeks compared to those with 34 weeks.

Physical growth and dietary characteristics of children with attention deficit hyperactivity disorder: a cross-sectional study / 中国当代儿科杂志

OBJECTIVES@#To investigate the physical growth and dietary characteristics of children with attention deficit hyperactivity disorder (ADHD), and to analyze their relationship with core symptoms of ADHD.@*METHODS@#A total of 268 children who were newly diagnosed with ADHD in Children's Hospital of Nanjing Medical University from June to December 2020 were included in the ADHD group, and 102 healthy children who underwent physical examination during the same period were selected as the control group. Physical evaluations and dietary surveys were conducted for both groups. ADHD diagnosis and scoring were performed according to the Diagnostic and Statistical Manual of Mental Disorders (5th edition). Factor analysis, Spearman correlation analysis, and mediation analysis were used to study the relationship between core symptoms of ADHD, dietary patterns, and physical growth.@*RESULTS@#The rate of overweight/obesity in the ADHD group was significantly higher than that in the control group (35.8% vs 21.6%, P<0.05). Three dietary patterns were extracted from the food frequency questionnaire: vegetarian dietary pattern, traditional dietary pattern, and snack/fast food pattern. The factor score for the snack/fast food pattern in the ADHD group was higher than that in the control group (P<0.05). There was a significant positive correlation between ADHD symptom scores, snack/fast food pattern factor scores, and body fat percentage (P<0.05). The mediation analysis showed that the snack/fast food pattern played a partial mediating role in the relationship between ADHD symptom scores and body fat percentage, with a mediation proportion of 26.66%.@*CONCLUSIONS@#The rate of overweight/obesity in children with ADHD is higher than that in non-ADHD children. Core symptoms of ADHD are related to dietary patterns and physical growth, with the snack/fast food pattern playing a partial mediating role in the relationship between core symptoms of ADHD and physical growth.

Follow-up and prognostic study of infants with positional plagiocephaly / 中国当代儿科杂志

OBJECTIVES@#To study the effects of infantile positional plagiocephaly on the growth and neural development.@*METHODS@#A retrospective study was conducted on the medical data of 467 children who underwent craniographic examination and were followed up to 3 years of age in Peking University Third Hospital from June 2018 to May 2022. They were divided into four groups: mild positional plagiocephaly (n=108), moderate positional plagiocephaly (n=49), severe positional plagiocephaly (n=12), and normal cranial shape (n=298). The general information of the four groups and the weight, length, head circumference, visual acuity screening results, hearing test results, and the scores of Pediatric Neuropsychological Developmental Scales/Gesell Developmental Schedules of the four groups from 6 to 36 months old were compared.@*RESULTS@#The rates of adverse perinatal factors, congenital muscular torticollis, and supine fixed sleeping posture in the mild, moderate, and severe positional plagiocephaly groups were higher than the normal cranial group (P<0.05). There was no significant difference in weight, length, and head circumference among the four groups at 6, 12, 24 and 36 months of age (P>0.05). The incidence rate of abnormal vision in the severe positional plagiocephaly group was higher than that in the mild positional plagiocephaly, moderate positional plagiocephaly and normal cranial shape groups at 24 and 36 months of age (P<0.05). The scores of the Pediatric Neuropsychological Developmental Scales at 12 and 24 months of age and the scores of the Gesell Developmental Schedules at 36 months of age in the severe positional plagiocephaly group were lower than those in the mild positional plagiocephaly, moderate positional plagiocephaly and normal cranial shape groups, but the difference was not statistically significant (P>0.05).@*CONCLUSIONS@#Adverse perinatal factors, congenital muscular torticollis, and supine fixed sleeping position may be associated with infantile positional plagiocephaly. Mild or moderate positional plagiocephaly has no significant impact on the growth and neural development of children. Severe positional plagiocephaly have adverse effects on the visual acuity. However, it is not considered that severe positional plagiocephaly can affect the neurological development.

Associations of sugar-sweetened beverages intake frequency with physical growth and glucolipid metabolism among children and adolescents / 环境与职业医学

Background Children and adolescents drink sugar-sweetened beverages (SSBs) frequently. Research has confirmed that SSBs associate with weight gain and overweight or obesity. However, it is unclear whether high SSBs intake associates with abnormal changes in physical growth and glucolipid metabolism before causing adverse health outcomes such as overweight and obesity. Early identification of associated health risks of overconsumption of SSBs have important public health implications. Objective To investigate the differences in physical growth and glucolipid metabolism between different SSBs intake frequency groups in normal weight children and adolescents aged 6-17 years, and to evaluate the early effects of SSBs intake on physical growth and glycolipid metabolism before causing overweight and obesity, aiming to provide a scientific basis for the prevention and control of childhood overweight and obesity and related chronic diseases, and for the formulation of policies on the control of SSBs consumption. Methods Data were from the Shanghai Diet and Health Survey (SDHS) among primary and secondary school students. The participants were normal weight children and adolescents aged 6-17 years. Propensity scores were calculated according to energy intake and physical activity factors, after stratifying by age and gender. Participants were 1:1 matched with the closest propensity scores in the high-frequency (≥1 time·d−1) and the low-frequency (≤1 time·week−1) SSBs intake groups. The outcome indicators were physical measurements such as height, weight, percent of body fat, and waist circumference, and metabolic indicators such as fasting blood glucose, total triglycerides, total cholesterol, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol. Body mass index (BMI) was calculated. Food frequency questionnaire was used to collect SSBs consumption in the past three months through face-to-face interview. A paired t-test was used to compare the differences in physical and glycolipid metabolic indicators between the high-frequency intake group and the low-frequency intake group of SSBs. Results A total of 431 pairs were obtained. For children and adolescents in grades 6-9, overall height (difference=2.92 cm, P=0.002), weight (difference=2.53 kg, P=0.003), and waist circumference (difference=1.34 cm, P=0.035) were higher in those who consumed SSBs ≥1 time·d−1 than in those who consumed ≤1 time·week−1. For children and adolescents in grades 10-12, overall weight (difference=2.27 kg, P=0.041) was higher in those who consumed SSBs ≥1 time·d−1 than in those who consumed ≤1 time·week−1. Over 95% of the study subjects reported blood glucose and lipid test results within the normal range; but girls in grades 1-5 who consumed SSBs ≥1 time·d−1 had a higher total cholesterol (difference=0.20 mmol·L−1, P=0.027) and low-density lipoprotein cholesterol (difference=0.19 mmol·L−1, P=0.010) than those who consumed ≤1 time·week−1; boys in grades 6-9 who consumed SSBs ≥1 time·d−1 had a lower high-density lipoprotein cholesterol (difference=-0.10 mmol·L−1, P=0.039) than those who consumed ≤1 time·week−1. Conclusion High-frequency intake of SSBs may be associated with higher total cholesterol and low-density lipoprotein cholesterol in normal weight children and adolescents in grades 1-5, and higher weight in normal weight children and adolescents in grades 6-12. There is an urgent need to educate children and adolescents about nutritional health, enhance their ability to make healthy food and beverage choices, and take early interventions to control the intake of SSBs in children.

Effects of different feeding patterns on physical and nutritional status of infants aged 6‒12 months / 上海预防医学

ObjectiveTo analyze the effects of different feeding patterns on the physical and nutritional status of children aged 6‒12 months， so as to provide reference for promoting scientific feeding and health development of infants and young children. MethodsChildren born between December 2019 and February 2020 and who had completed three follow-up visits at 6‒， 9‒ （8‒10 months） and 12‒ （11‒14 months） months old in all of the 13 communities of Minhang， Shanghai were selected. The subjects’ basic information was investigated by questionnaires. The indicators including feeding pattern， physical development （body weight， body length， head circumference） and nutritional status （the detection rate of overweight， obesity， low body weight， growth retardation， emaciation and iron deficiency anemia） were followed up in the outpatient department， with iron deficiency anemia only monitored at the 6‒ and 12‒ months old. According to different feeding patterns， the groups of 6‒ months old were divided into three groups of exclusive breast feeding （EBF）， mixed feeding （MF） and artificial feeding （AF）， while 9‒ and 12‒ months old were divided into MF and AF groups. The differences of basic information and follow-up results among the groups were analyzed. ResultsA total of 470 children were included， including 130 （27.66%）， 288 （61.28%） and 52 （11.06%） respectively in EBF， MF and AF groups at the 6‒ months old，and 319 （67.87%） and 196 （41.70%） in MF group at the 9‒ and 12‒ months old. There was no significant difference in the other follow-up results among the groups. The detection rate of iron deficiency anemia in 6‒ months old EBF （13.08%） was higher than that in MF group （5.90%） and AF group （1.92%） （χ2=8.40， P=0.010）， while it was still higher in 12‒ months old MF group （9.69%） than in AF group （2.92%） （χ2=9.68， P=0.002）. ConclusionThere is no significant difference in body weight，body length， head circumference， and the detection rates of overweight， obesity， low body weight， growth retardation and emaciation among the groups of different feeding patterns in the children aged 6‒12 months. The detection rate of iron deficiency anemia in the EBF and MF groups is significantly higher than that in the AF groups of children aged 6‒ and 12‒ months old.

Physical growth and neurodevelopment of preterm infants at the corrected age of 18-24 months / 中国当代儿科杂志

OBJECTIVES@#To investigate the levels of physical growth and neurodevelopment in preterm infants at the corrected age of 18-24 months.@*METHODS@#The physical growth data and neurodevelopment data of 484 preterm infants at corrected age of 18-24 months were prospectively collected by a post-discharge follow-up system for preterm infants. The infants were regularly followed up in Shenzhen Bao'an Maternal and Child Health Hospital Affiliated to Jinan University from April 2018 to December 2021. The neurodevelopment was evaluated by the Children Neuropsychological and Behavioral Scale-Revision 2016. A total of 219 full-term infants served as controls. The infants were divided into groups (extremely preterm, very preterm, moderate late preterm, and full-term) based on gestational age, and the groups were compared in the levels of physical growth and neurodevelopment.@*RESULTS@#Except that the moderate preterm group had a higher length-for-age Z-score than the full-term group (P=0.038), there was no significant difference in physical growth indicators between the preterm groups and the full-term group (P>0.05). Each preterm group had a significantly lower total developmental quotient (DQ) than the full-term group (P<0.05). Except for the social behavior domain, the DQ of other domains in the extremely preterm and very preterm groups was significantly lower than that in the full-term group (P<0.05). The <32 weeks preterm group had a significantly higher incidence rate of global developmental delay than the full-term group (16.7% vs 6.4%, P=0.012), and the incidence rate of global developmental delay tended to increase with the reduction in gestational age (P=0.026).@*CONCLUSIONS@#Preterm infants can catch up with full-term infants in terms of physical growth at the corrected age of 18-24 months, but with a lower neurodevelopmental level than full-term infants. Neurodevelopment monitoring and early intervention should be taken seriously for preterm infants with a gestational age of <32 weeks.

Objective:To investigate thyroid function, physical growth, and psychological and behavioral development in children with congenital hypothyroidism.Methods:Thirty-two children with congenital hypothyroidism who were born in Yuyao People's Hospital from January 2014 to December 2018 were included in the observation group. Thirty healthy neonates who were born in the same period were included in the control group. Thyroid function index changes at the age of 1 year relative to at birth, physical, intellectual, and neuropsychological development and bone age at the age of 1 year were compared between the observation and control groups.Results:Thyroid-stimulating hormone level at birth was significantly higher in the observation group than in the control group [(18.23 ± 2.71) mU/L vs. (2.85 ± 0.34) mU/L, t = 30.84, P < 0.001]. Free thyroxine level at birth was significantly lower in the observation group than in the control group [(6.76 ± 1.54) pmol/L vs. (17.91 ± 2.04) pmol/L, t = 24.39, P < 0.001]. In the observation group, thyroid-stimulating hormone and free thyroxine levels at the age of 1 year were (2.68 ± 0.78) mU/L and (17.26 ± 2.11) pmol/L, respectively, which were not significantly different from those in the control group [(2.77 ± 0.63) mU/L and (17.54 ± 2.20) pmol/L, t = 0.50, 0.51, both P > 0.05]. Body weight, body length, head circumference, and bone age at the age of 1 year were (9.21 ± 1.20) kg, (79.84 ± 3.05) cm, (43.73 ± 1.42) cm, (1.01 ± 0.15) years old, respectively in the observation group, which were significantly lower than those in the control group [(10.12 ± 1.32) kg, (84.54 ± 3.41) cm, (45.85 ± 2.04) cm, (1.14 ± 0.28) years old, t = 2.84, 5.73, 4.77, 2.30, P < 0.05]. The proportion of children patients with bone age lag was significantly higher in the observation group than in the control group [21.88% (7/32) vs. 3.33% (1/30), χ2 = 4.74, P < 0.05]. There was a significant difference in intellectual development at the age of 1 year between the two groups ( χ2 = 7.05, P < 0.05). Gross movement, fine movement, adaptability, language ability, and social ability in the observation group were scored (90.43 ± 6.96) points, (92.03 ± 6.03) points, (88.45 ± 4.85) points, (84.04 ± 5.71) points, and (85.05 ± 6.17) points, respectively, which were significantly lower than those in the control group [(99.47 ± 5.40) points, (104.12 ± 5.71) points, (98.47 ± 5.22) points, (94.16 ± 4.98) points, and (104.34 ± 5.70) points ( t = 5.69, 8.09, 7.84, 7.42, 12.76, all P < 0.001]. Conclusion:Neonate patients with congenital hypothyroidism have obvious physical growth and psychological and behavioral development disorders. Early screening and treatment of neonatal congenital hypothyroidism should be strengthened to improve the prognosis.

Effect of early comprehensive interventions on physical growth and nervedevelopment among premature infants / 预防医学

Objective@#To examine the effect of early comprehensive interventions on the physical growth and nerve development among premature infants, so as to provide insights into the follow-up management of premature infants after discharge from hospital.@*Methods@#A total of 130 premature infants delivered in Shaoxing Municipal Maternal and Child Health Care Hospital from 2019 to 2021 were selected and divided into high- and low-risk groups according to gestational age and birth weight, while 306 full-term normal infants in the same hospital during the study period served as controls. All premature infants were given early comprehensive interventions until age of 12 months, including nutritional support and parental guidance of children's feeding and development, and all normal infants received periodical health checkup according to the basic public health service program. All infants received periodical measurements of height, weight and head circumference, and the 12-month intellectual and motor development ability was measured using the Bayley Scales of Infant Development revised in Chinese cities was used to assess. Infants' physical growth, mental development index (MDI) and motor development index (PDI) were compared among groups.@*Results@#There were 130 premature infants with gestational ages of 28 to 36 weeks and birth weight of 1 200 to 3 440 g, including 79 male infants, and there were 80 infants in the low-risk group and 50 infants in the high-risk group. The full-term infants had a gestational age of 37 to 42 weeks, and birth weights of 2 500 to 4 000 g, including 162 male infants. There were significant differences in height (Wald χ2=28.664, P<0.001) and head circumference growth (Wald χ2=19.312, P=0.013) among the three groups as revealed by the generalized estimating equation; however, no significant differences were seen in the 12-month weight (F=0.639, P=0.528), height (F=1.051, P=0.350) or head circumference (F=0.318, P=0.728) among the three groups. The percentages of abnormal MDI were 2.00%, 0 and 1.31% among the high-risk premature infants, low-risk premature infants and full-term infants at ages of 12 months (χ2=1.319, P=0.517), while the percentages of abnormal PDI were 20.00%, 7.50% and 5.56% among the three groups at ages of 12 months (χ2=12.818, P=0.002).@*Conclusions@#Following implementation of early comprehensive interventions, the premature infants have favorable physical growth and comparable MDI with full-term infants; however, a high percentage of abnormal PDI is seen in high-risk premature infants. An improvement in the motor development among high-risk premature infants is recommended to be emphasized during the management of premature infants.

Effect of prophylactic use of hydrolyzed protein formula on gastrointestinal diseases and physical growth in preterm infants: a Meta analysis / 中国当代儿科杂志

OBJECTIVES@#To systematically evaluate the effect of prophylactic use of hydrolyzed protein formula on gastrointestinal diseases and physical development in preterm infants.@*METHODS@#A computerized search was performed in the databases including China National Knowledge Infrastructure, Wanfang Data, Weipu, PubMed, Embase, and the Cochrane Library to identify randomized controlled trials of the effect of prophylactic use of hydrolyzed protein formula on gastrointestinal diseases and physical growth in preterm infants. RevMan 5.3 software was used to perform a Meta analysis for the included studies.@*RESULTS@#A total of 7 randomized controlled studies were included. The results of Meta analysis showed that compared with the whole protein formula, the prophylactic use of hydrolyzed protein formula could reduce the risk of neonatal necrotizing enterocolitis (RR=0.40, P=0.04) and feeding intolerance (RR=0.40, P=0.005), and had no significant effect on the growth of weight, length and head circumference (P>0.05).@*CONCLUSIONS@#Compared with the whole protein formula, the prophylactic use of hydrolyzed protein formula in preterm infants may reduce the occurrence of necrotizing enterocolitis and feeding intolerance, and can meet the nutrient requirement of physical development. However, the evidence is limited, and the results of this study cannot support the routine prophylactic use of hydrolyzed protein formula in preterm infants.

Relationship between nutritional status and growth and development of children aged 1-12 / 公共卫生与预防医学

Objective To analyze the nutritional status and growth and development of children aged 1 to 12 years old, and to provide guidance for subsequent child health care work. Methods A total of 514 children aged 1 to 12 years old underwent physical examination in our hospital were enrolled, data including weight, height, bone mineral density, serum vitamin A, vitamin D and blood trace elements were detected, thereafter, Pearson correlation analysis was used to discuss the correlation between children's growth and development and serum trace elements. Results Among the 514 children in this study, there were 224 boys and 290 girls, including 86 children in early childhood group, 165 children in preschool age group and 263 children in school age group. The prevalence of vitamin A deficiency was 7.98% (41/514), with a significant difference among the different age groups, including 22.09% (19/86) in early childhood group, 7.88% (13/165) in preschool age group, and 4.56% (12/263) in school age group. The height and weight of children with vitamin A deficiency were lower than those of children in the same age group, and there was a positive correlation between serum vitamin A concentration and height and weight of children (P<0.05). The detection rate of vitamin D deficiency was 12.06% (62/514), with 16.07% (36/224) in girls, higher than 8.97% (26/290) in boys. The height of children with vitamin D deficiency was significantly lower than that of children with normal vitamin D levels (P<0.05), and the incidence of bone mineral deficiency was significantly higher than that of that with normal vitamin D levels. Serum vitamin D concentration was positively correlated with height in children (P<0.05) and negatively correlated with bone mineral deficiency (P<0.05). In addition, there were 51 children (9.92%) with hypocalcemia. Serum calcium levels were significantly lower in boys than in girls (P<0.05), and the incidence of hypocalcemia was significantly higher in boys than in girls (P<0.05).Serum calcium level was positively correlated with height (P<0.05), and negatively correlated with bone mineral deficiency (P<0.05). There were 35 cases (6.81%) of children with hypoglycemic zinc and 32 cases (6.23%) of children with hypoglycemic iron, and there was a positive correlation between serum zinc and iron levels and children's height and weight (P<0.05). Conclusions Vitamin A deficiency is more serious in younger children than in older children, and vitamin A deficiency affects children's height and weight; vitamin D deficiency is more serious in girls than in boys, and vitamin D deficiency affects children's bone density. Vitamin D supplementation and outdoor activities for girls are recommended. In addition, deficiencies in trace vitamins, including blood calcium, zinc and iron, will also affect children's height and weight, and a proper diet is recommended to supplement the body with essential elements.

Assessment of growth pattern of preterm infants up to a corrected age of 24 months / 中国当代儿科杂志

OBJECTIVES@#To assess the growth of preterm infants up to a corrected age of 24 months, and to understand the growth trend and pattern of preterm infants.@*METHODS@#A preterm infant follow-up database was established based on the Internet Plus follow-up system. A total of 3 188 preterm infants who were born from April 2018 to April 2021 were enrolled. Their length, weight, and head circumference were recorded at birth and at the corrected ages of 1, 3, 6, 12, 18, and 24 months. The preterm infants were grouped by perinatal factors. The growth curves of these infants were plotted and compared with the International Fetal and Newborn Growth Consortium for the 21st Century (INTERGROWTH-21st) standard and World Health Organization (WHO) standard.@*RESULTS@#The weight, length, and head circumference curves of each group of preterm infants grouped by various perinatal factors all rose rapidly within the corrected age of 6 months, but the growth rate slowed down after the corrected age of 6 months. Based on the actual age for the groups of preterm infants with different gestational ages (<28 weeks, 28-31@*CONCLUSIONS@#The physical growth rate of preterm infants is faster within the corrected age of 6 months, and the growth rate slows down after the corrected age of 6 months. Preterm infants with a smaller gestational age need longer time to catch up in weight and head circumference. More attention should be paid to the physical growth of extremely preterm infants, extremely low birth weight infants, and small-for-gestational-age infants.

Evaluation of physical and neurocognitive development of infants conceived from frozen embryo transfer / 上海交通大学学报（医学版）

Objective • To evaluate the physical and neurocognitive development of infants conceived from frozen embryo transfer (FET). Methods • Two hundred and forty-eight infants (1.5-4 years old) conceived from FET and natural conception (NC) were recruited as the follow-up cohort of FET offspring, and their physical and neurocognitive development were followed up and evaluated. Multiple Logistic regression analysis was used to assess the potential risk of cognitive retardation in FET offspring. Results • There was no significant difference in composition ratio of Z score for height, weight and body mass index between the FET group and the NC control group. Multiple Logistic regression analysis showed that compared with the NC control group, the risk of neurocognitive development abnormalities and retardation was higher in the FET group, especially in fine motor (OR=3.01, 95%CI 1.48-6.11) and social development domains (OR=3.76, 95%CI 1.63-8.69); and in the FET group, the social development risk of female infants was higher than that of male infants. Conclusion • FET may exert a negative impact on the early neurocognitive development of infants.

Study on the physical growth status of birthweight discordant twins under 4 years old / 中国实用儿科杂志

OBJECTIVE: To study the physical growth characteristics of birthweight discordant twins(BDT)under 4 years old. METHODS: The physical growth characteristics of BDT under 4 years old born from September 2010 to December 2017 in child health care system of Children's Hospital of Chongqing Medical University were analyzed retrospectively. R 3.5.3 was used to clean up the database,analyze the distribution of different degree of birthweight discordance,and draw the fitting curves. More than 20% of birth weight difference was taken as inclusive criteria of BDT. BDT were divided into preterm or full-term groups,and low birthweight or normal birthweight groups respectively. SPSS 19.0 software was used for statistical analysis. RESULTS: A total of 141 pairs of BDT were included,accounting for 15.4%(141/916). The degree of birthweight difference in premature BDT was higher than that of full-term BDT(t=3.820,P<0.001). The growth discordance of preterm BDT lasted longer. Physical growth of low/very low birthweight BDT was slower than that of normal birthweight BDT under 4 years old. The growth status of BDT didn't reach the average level of WHO growth chart by the time of the last follow-up. CONCLUSION: Birthweight discordance of twins could have longlasting effects on further growth and development. Preterm twins have higher degree of birthweight discordance,and the growth discordance lasts longer. Low birthweight is an important reason for growth retardation of the lighter BDT.Growth of BDT should be monitored regularly to increase follow-up compliance.

Long-term Outcomes of Augmentation Cystoplasty in a Pediatric Population With Refractory Bladder Dysfunction: A 12-Year Follow-up Experience at Single Center / 대한배뇨장애요실금학회지

PURPOSE: Augmentation cystoplasty (AC) is a surgical procedure used in adults and children with refractory bladder dysfunction, including a small bladder capacity and inadequate bladder compliance, and in whom conservative and medical treatment has failed. This study was aimed to determine the long-term outcomes of AC in children. METHODS: A retrospective analysis was conducted of 42 patients (31 males; mean age, 14.2±6.2 years) who underwent AC for neurogenic and nonneurogenic bladder dysfunction, with a median 12.0±1.5 years of follow-up. All patients underwent AC using the ileum with or without continent reconstruction. Pre-AC, concurrent, and post-AC procedures and complications were analyzed. Patients who underwent ureterocystoplasty, were lost to follow-up, or had less than 10 years of follow-up were excluded. The primary outcomes were the complication and continence rates, the post-AC linear rate of height and weight gain, and renal function. The Student t-test was used to evaluate between-group differences and the paired t-test was used to evaluate longitudinal changes in measured variables. RESULTS: Renal function was stable or improved in 32 of 42 patients (76.2%), with a post-AC continence rate of 88.1%. Thirty patients (71.4%) required 72 procedures post-AC. There was no statistically significant difference in the mean percentile of height (P=0. 212) or weight (P=0.142) of patients in the pre- and post-AC periods. No cases of bladder perforation or malignancy were detected. CONCLUSIONS: We consider AC to be a safe and effective procedure that does not negatively affect future physical growth, while achieving a good rate of stable renal function. Patients need long-term follow-up to address long-term complications.

Effects of three different ways of feeding on physical growth of low birth weight premature infants after discharge / 中国基层医药

Objective To investigate the effects of three different ways of feeding on the physical growth of low birth weight premature infants discharged from hospital.Methods 90 premature infants were selected.According to the different feeding methods,the infants were divided into A,B,C groups.Premature infants of A group were fed with preterm infants formula milk after discharge.B group received breast feeding.C group was fed with term infants formula milk.The physical growth at postnatal 30d,60d and 90d of three groups were observed and compared.Results The weight,length and head circumference of premature infants at postnatal 30d,90d in A group were better than those of B group and C group,the differences were statistically significant (all P ＜ 0.05).The weight,length and head circumference of premature infants at postnatal 60d in A group were similar to those in B group,the differences were not statistically significant (all P ＞ 0.05).The weight,length and head circumference of premature infants at postnatal 60d in A group and B group were better than those in C group,the differences were statistically significant (all P ＜0.05).Conclusion Compared with the breast feeding and traditional formula milk,formula milk for preterm infants is more conducive to the growth of premature infants to obtain nutrients,effectively promote the growth of premature infants,improve the prognosis and quality of life in preterm infants.

Investigation of physical growth in 115 infants with eczema / 临床儿科杂志

Objective To explore the physical growth in infants with eczema who treated with regular use of glucocorticoid.Methods A total of 115 full-term infants newly diagnosed with eczema were included in this study and treated with topical glucocorticoids regularly.The severity of eczema was assessed and anthropometric indices were measured regularly.Results Both weight for age (WAZ) and length for age (LAZ) at birth and 6-month-old were higher than those of World Health Organization (WHO) child growth standards.However,the LAZ at diagnosis and 3 months after treatment were lower than that of WHO child growth standards.The weight,length,and the growth rate from birth to the time of diagnosis were all lower than those of WHO child growth standards.While the growth rate after treatment for 3 to 6 months was higher than that of WHO child growth standards.The increases of WAZ and LAZ were significantly different among three periods:at birth to diagnose,at diagnosis to 3 months after treatment,and 3 months to 6 months after treatment (P＜0.001).Conclusion In the early stage of eczema,the growth rate was decreased when the symptoms were not controlled.However,after treatment,the growth rate was increased.It is suggested that treatment of regular topical glucocorticoids has no adverse effects on growth of eczema infants,and also is beneficial to the catch-up growth of infants.

Percentile curves on growth among breastfed 1-4 year olds in 8 urban areas / 中华流行病学杂志

Objective To construct the growth percentile curves of weight-,length/height-,head circumference and BMI for 1 to 4 year-olds who had been breastfed in urban areas.Methods Data was from the longitudinal study on 1 025 breastfed children aged 1 to 4 years,in 8 urban areas during 2008-2012.MLwiN2.25 was selected to construct the multi-level models of weight-for-age,length for-age,head circumference-for-age and BMI-for-age.The models included many growth relevant factors including gender,age,family and social demographic characteristics,perinatal factors,parent biological characteristics,dietary patterns and diseases of childen.Based on these models,predicted values (P3,P15,P50,Ps5,P97) were estimated to fit the percentiles reference curves.Results The percentiles reference curves of weight-,length/height,head circumferenceand BMI-for-age for the 1-4 year-olds who had been breastfed in the urban areas were developed.Differences of all the indicators between boys and girls were statistically significant (P＜0.001).Weight,length/height,head circumference and BMI were higher in boys than those in girls,with an average differences as 0.56-0.76 kg,0.89-1.12 cm,0.64-0.91 cm and 0.31-0.52 kg/m2.Conclusion The percentiles reference curves on growth,constructed by the longitudinal observational data and scientific method,were important in reflecting the development ofbreastfed children in urban areas.

Performance motora em crianças indígenas kaingang / Motor performance in Kaingang indigenous children

INTRODUCTION: Studies on indigenous children show low height for age, however there is a lack of literature on motor performance in these populations. Motor performance tests are important indicators in identifying factors of physical fitness related to health. OBJECTIVE: To compare the motor performance in Kaingang indigenous children. METHODS: The study was descriptive and cross-sectional with 78 Kaingang schoolchildren aged between 8 and 9 years from the indigenous area of Rio das Cobras, in Paraná, Brazil. The children were classified into two groups, Group A below (GA) and Group B (GB) above the -2 z-scores for the reference stature for age from the Centers for Disease Control and Prevention/National Center for Health Statistics. The data were collected using anthropometric measurements of their stature and motor performance tests for sitting and reaching (flexibility), jumping distance (muscle power), sitting and lying down (strength and muscular resistance) and coming and going (agility). Analysis of covariance (p < 0.05) was used to compare the stature between the groups as well as their motor performance, controlled by age, and separated per sex RESULTS: Among the 78 schoolchildren evaluated, 45.5% of boys and 55.5% of girls were below the -2 z-scores for stature at their age, classified in GA, and 54.5% of boys and 44.5% of girls were above the -2 z-scores for stature at their age, classified in GB. There was a significant difference in stature between the groups, in both sexes. There was a significant difference in the motor performance tests between children classified as having a short stature and those not characterized as such, in both sexes. CONCLUSION: Short stature did not influence motor performance in the children studied.

INTRODUÇÃO: Estudos em crianças indígenas apontam a baixa estatura para idade, entretanto existe escassez na literatura sobre performance motora nestas populações. Testes de performance motora são importantes indicadores para verificar fatores da aptidão física relacionada a saúde. OBJETIVO: Comparar a performance motora em crianças indígenas Kaingang. MÉTODO: O estudo caracterizou-se por ser descritivo e transversal e dele participaram 78 escolares entre 8 e 9 anos de idade, da etnia Kaingang da terra indígena Rio das Cobras, Paraná, Brasil. As crianças foram classificadas em dois grupos: Grupo A (GA) abaixo e Grupo B (GB) acima de -2 escore z de estatura para idade da referência Centers for Disease Control and Prevention/National Center for Health Statistics. Os dados foram coletados por meio da medida antropométrica da estatura e dos testes de performance motora: sentar e alcançar (flexibilidade), salto em distância (potência muscular), sentar e deitar (força e resistência muscular) e ir e vir (agilidade). Utilizou-se a analysis of covariance (p<0,05) para comparar a estatura entre os grupos, bem como a performance motora entre os grupos, controlando pela idade, com separação por sexo. RESULTADOS: Entre os 78 escolares avaliados, 45.5% dos meninos e 55.5% das meninas encontram-se abaixo de -2 escore z de estatura para a idade, classificados no GA, e 54.5% dos meninos e 44.5% das meninas acima de -2 escore z de estatura para a idade, classificados no GB, havendo diferença significativa em estatura entre os grupos, em ambos os sexos. Não houve diferença significativa nos testes de performance motora entre as crianças com baixa estatura e aquelas não caracterizadas com baixa estatura, em ambos os sexos. CONCLUSÃO: A baixa estatura não influenciou a performance motora das crianças estudadas.
