ABSTRACT
This paper is an attempt to assess the levels of regional development in Haryana in 2011. The basic unit of analysis is district. There are eight variables chosen for the measurement of the regional development levels in Haryana which are: Share of urban population, Literacy Rate, No. of Recognized High/Sr. Sec. Schools per 100 km² area, No. of Medical Institutions Per 100 km² area, No. of Medical Institutions Per Lakh Population, No. of Rural Development Co- operative Societies per Lakh Population, No. of registered working factories per 100 km² and Workers employed in registered working factories per Lakh Population. Further, Z- Scores have been computed for district wise scores of each indicator to prepare a composite index of regional development. By this exercise, it has been observed that Faridabad is the most developed district of the state, whereas Mewat is the most backward district of Haryana
ABSTRACT
ObjectiveTo investigate the factors influencing the catch-up growth of 12-months low birth weight infants in Suyu District of Suqian City during the period of COVID-19 prevention and control. MethodsAll 301 low birth weight infants were selected with clustered sampling from the database under authorized use， who made their regular check-ups and follow-ups to 12 months in Suyu District of Suqian City from January 2020 to May 2021. Data were collected on infants’ basic information， their birth situation and their weight upon birth and at12 months， while maternal situation during pregnancy and the infants’ postnatal feeding and diseases were investigated with a questionnaire.Z scores were calculated. All infants were divided into the catch-up growth group and the uncompleted catch-up growth group according to whether the △Z score was ≥0.67. The influencing factors were analyzed for catch-up growth of the low birth weight infants during the period of COVID-19 prevention and control. ResultsThere were statistically significant differences in the rate of small for gestational age， preterm birth， intrauterine growth retardation， postnatal nutrition enhancement and feeding mode between the two groups. The results in the multifactor logistics regression analysis showed that intrauterine growth retardation （OR=0.070， 95%CI： 0.015‒0.327） was an obstacle factor for catch-up growth， while postnatal fortified nutrition （OR=6.518， 95%CI 1.215‒34.955） was a promoting factor for catch-up growth. ConclusionThere is catch-up growth in postnatal weight among most of the low birth weight infants. Postnatal fortified nutrition is beneficial to catch-up growth， while intrauterine growth retardation may induce uncompleted catch-up growth.
ABSTRACT
Stunting is a significant public health problem in low- and middle-income countries. This study assessed the prevalence of stunting and associated risk factors of stunting among preschool and school-going children in flood-affected areas of Pakistan. A cross-sectional study was conducted by visiting 656 households through multi-stage sampling. Respondent's anthropometric measurements, socio-demographic information and sanitation facilities were explored. A logistic regression model was used to determine determinants of stunting, controlling for all possible confounders. The overall prevalence of stunting in children was 40.5%, among children 36.1% boys and 46.3% of girls were stunted. The prevalence of stunting in under-five children was 50.7%. Female children (OR=1.35, 95% CI:0.94-2.0), children aged 13-24 months (OR=6.5, 95% CI: 3.0-13.9), mothers aged 15-24 years (OR=4.4, 95% CI: 2.6-7.2), joint family (OR=2.1, 95% CI: 1.4-3.0) did not have access to improved drinking water (OR=3.3, 95% CI: 1.9-5.9), and the toilet facility (OR=2.8, 95% CI, 1.9-4.3), while the children from district Nowshera (OR=1.7, 95% CI: 0.9-3.2) were significantly (P<0.05) associated in univariate analysis. The regression model revealed that child age, maternal age, family type, quality of water, and toilet facility, were the significant (P<0.05) factors contributing to child stunting in the flood-hit areas. Identification of key factors might be helpful for policymakers in designing comprehensive community-based programs for the reduction of stunting in flood-affected areas. In disasters such as flood, the detrimental consequences of the stunting problem could be even more on children. Evidence-based education and care must be provided to the families in the flood-affected regions to reduce the stunting problem. The determinants of stunting should be targeted by making comprehensive policies regarding proper nutrition, livelihood, clean water, and sanitation facilities in flood-hit regions.
A baixa estatura é um problema significativo de saúde pública em países de baixa e média renda. Este estudo avaliou a prevalência de nanismo e os fatores de risco associados de nanismo entre crianças em idade pré-escolar e em idade escolar em áreas afetadas por inundações do Paquistão. Foi realizado um estudo transversal visitando 656 domicílios por meio de amostragem em múltiplos estágios. As medidas antropométricas do entrevistado, informações sociodemográficas e instalações de saneamento foram exploradas. Um modelo de regressão logística foi usado para determinar os determinantes do nanismo, controlando todos os possíveis fatores de confusão. A prevalência geral de baixa estatura em crianças foi de 40,5%, entre as crianças 36,1% dos meninos e 46,3% das meninas com baixa estatura. A prevalência de baixa estatura em crianças menores de 5 anos foi de 50,7%. Crianças do sexo feminino (OR = 1,35, IC de 95%: 0,94-2,0), crianças de 13-24 meses (OR = 6,5, IC de 95%: 3,0-13,9), mães de 15-24 anos (OR = 4,4, IC de 95%: 2,6-7,2), família conjunta (OR = 2,1, IC 95%: 1,4-3,0) não tiveram acesso a água potável de qualidade (OR = 3,3, IC 95%: 1,9-5,9) e a banheiro (OR = 2,8, IC de 95%, 1,9-4,3), enquanto as crianças do distrito de Nowshera (OR = 1,7, IC de 95%: 0,9-3,2) foram significativamente (P < 0,05) associadas na análise univariada. O modelo de regressão revelou que a idade da criança, idade materna, tipo de família, qualidade da água e banheiro foram os fatores significativos (P < 0,05) que contribuíram para a baixa estatura infantil nas áreas afetadas pelas enchentes. A identificação de fatores-chave pode ser útil para os formuladores de políticas no planejamento de programas comunitários abrangentes para a redução da baixa estatura em áreas afetadas pelas enchentes. Em desastres como enchentes, as consequências prejudiciais do problema de baixa estatura podem ser ainda maiores para as crianças. Educação baseada em evidências e cuidados deve ser fornecida às famílias nas regiões afetadas pelas enchentes para reduzir o problema de nanismo. Os determinantes do retardo de crescimento devem ser almejados pela formulação de políticas abrangentes sobre nutrição adequada, meios de subsistência, água potável e instalações de saneamento nas regiões afetadas pelas enchentes.

Objective:To investigate the application value of fetal heart quantification (fetal HQ) in the evaluation of fetal heart size, morphology and function in fetuses with right ventricular outflow obstruction (RVOTO).Methods:Fifty-five fetuses diagnosed as RVOTO by fetal echocardiography in Sir Run Run Shaw Hospital Affiliated to Medical College of Zhejiang University from April 2020 to February 2021 were selected. They were divided into simple pulmonary artery stenosis (PS) group and conus arteriosus malformation (CTD) group according to whether they were combined with other cardiovascular malformations. On the standard four chamber view, the end diastolic basal apical length (4CV length) and transverse width (4CV width) were obtained by fetal HQ analysis technique, and the cardiac global spherical index (4cv-gsi) was calculated. The left and right ventricles (LV and RV) were divided into 24 segments from the base to the apex. The endocardial curve was obtained by total HQ tracking. The 24 segment transverse width (ED), spherical index (SI), short axis shortening (FS) and its Z-score were calculated. The LV and RV of RVOTO fetuses were compared and analyzed from the aspects of heart size, morphology and function.Results:The 4CV length of RVOTO fetal heart was in the normal range, 4CV width increased in varying degrees, GSI decreased, and the whole heart showed spherical changes. In PS group, LV-ED was larger than that of RV and the difference was statistically significant in 5-24 segments( P<0.05). LV was more spherical than RV. There was no significant difference in ED between LV and RV in CTD group( P>0.05), and RV was more spherical than LV. Twenty-four segment FS decreased in different degrees in RVOTO fetal heart, and the decrease of RV was more obvious than that of LV. There was significant difference between the LV and RV in PS group from S5 to 19 ( P<0.05), and there was significant difference between the left and right ventricles in CTD group from S1 to 11 ( P<0.05). Conclusions:Fetal HQ can provide new insights of cardiac size, morphology and function in fetuses with RVOTO.
ABSTRACT
@#<b>Objective</b> To investigate the differences in output results between difference analysis software, and to provide a reference for the improvement of quality control and the standard revision of SPECT equipment. <b>Methods</b> The image analysis software for quality control held by 14 radiological health technical service institutions was selected as the research subjects using the cluster sampling method. The results of the comparison were analyzed and evaluated according to the Z-score method with certified reference values. <b>Results</b> In the comparison items of “intrinsic uniformity” and “intrinsic spatial linearity”, the number of software with suspicious, deviated and incorrect results accounted for a relatively high proportion, while the results of other comparison items were satisfactory. <b>Conclusion</b> The applicability of SPECT image analysis software lacks effective supervision measures. Relevant departments should introduce feasible measures to standardize the software production and update process, accelerate the construction of radiological health information reporting platform, and promote the healthy development of the radiation health testing industry.
ABSTRACT
Background Evidence on the association between greenness and adiposity in children and adolescents is inconsistent and mostly from developed countries. Relatively limited evidence is from China. Objective To assess the association between greenness and adiposity in children and adolescents based on satellite remote sensing data. Methods From 2016 to 2018, a cross-sectional study was conducted among 52316 children and adolescents aged 5-18 years in three cities in the Pearl River Delta region of China. Basic sociological and demographic characteristics of the population and adiposity levels were collected through questionnaires. Land Remote-Sensing Satellite (Landsat) data and moderate-resolution imaging spectroradiometer (MODIS) products were used to quantify the greenness around the schools and homes, including normalized difference vegetation index (NDVI), vegetation continuous field (VCF), soil-adjusted vegetation index (SAVI), and enhanced vegetation index (EVI) calculated within 500 m and 1000 m buffers centered around the participants' homes or schools. A restricted cubic spline function was used to assess the exposure-response relationship. After categorizing greenness levels into quartiles with the first quartile as the reference, two-level generalized linear models were applied to assess the change in body mass index z-scores (zBMI) and the risk of overweight of children and adolescents in higher quartiles relative to the lowest quartile. In addition, counterfactual framework modelling was applied to assess the potential mediation effects of PM2.5 and NO2, and physical activity levels on the associations between greenness and adiposity levels. Results Of the 52316 children included, 8406 (16.1%) were overweight. A non-linear negative association of the level of greenness around the homes or schools and zBMI was found, with a significant lower zBMI in children and adolescents when a certain level of greenness was reached. After adjusting for confounders, the participants in the highest quartile had a significantly lower level of zBMI and a significantly lower risk of overweight compared with those in the lowest quartile of NDVI500 m and VCF500 m. The estimate change (\begin{document}$b$\end{document}) for zBMI was −0.07 (95%CI: −0.10-−0.04) and the odds ratio (OR) for overweight was 0.92 (95%CI: 0.85-0.99) for the students in the highest NDVI500 m quartile based on home address compared to those in the lowest quartile. Significant negative associations were also observed when 1000 m buffer, SAVI, and EVI were used. The mediation analysis showed that PM2.5 and NO2 partially mediated the negative association of NDVI500 m with zBMI , and the proportions of mediation were 50% (95%CI: 20%-80%) and 90% (95%CI: 50%-160%), respectively while no significant mediation effect was observed for physical activity level. Conclusion Higher levels of greenness surrounding homes or schools may be associated with a reduced risk of overweight and decreased zBMI in children and adolescents, and such associations may be partially mediated by reducing air pollutant concentrations.

ABSTRACT
Objective:To analyze the characteristics of coronary artery lesions in infants under 6 months of age with Kawasaki disease(KD), and to explore their regression and risk factors.Methods:The clinical data of 61 infants with KD[34 boys, 24 girls, aged 2.2 (1.7, 3.1) months] admitted to the department of critical care medicine and neonatology, Children′s Hospital, Capital Institute of Pediatrics from October 2015 to February 2020 were retrospectively analyzed.Persistent coronary artery aneurysm(CAA)was defined as the persistent enlargement of coronary arteries(coronary Z-score≥2.5)on echocardiograms at 12 months after KD onset.Cox proportional hazards mode was conducted to evaluate the potential risk factors of persistent CAA.Results:The incidence of CAA in 61 infants with KD was 52.5% (32/61) and occurred on 5 (4, 8)d of the disease course.During a follow-up of 547 (399, 782)d, five(8.2%, 5/61)infants satisfied the definition of persistent CAA.The median recovery time of CAA was 20 (12, 82)d after KD onset.Cox proportional hazards mode revealed that the maximal coronary Z-score was an independent factor of CAA regression( HR=0.451, 95% CI 0.293-0.694, P<0.001). Receiver operating characteristic curve analysis showed that the best cutoff value of coronary Z-score for predicting persistent CAA was 6.15(sensitivity 80.0%, specificity 97.7%). Conclusion:CAA is common in infants younger than 6 months with KD.The maximal coronary Z-score is an independent factor of persistent CAA.
ABSTRACT
Objective:Pulmonary annulus index is used to predict the application value of transannular patch in children with tetralogy of Fallot.Methods:A retrospective analysis of 130 patients with pediatric heart disease diagnosis of TOF and undergoing TOF repair in Beijing Anzhen Hospital affiliated to Capital Medical University from December 2018 to December 2019, 112 cases were included in this study, 18 cases were excluded. They were divided into TAP group and no TAP group, related values of pulmonary annulus and aortic annulus were measured. The pulmonary annulus index, the pulmonary annulus Z-score and main pulmonary artery Z-score were calculated to do statistically analyze.Results:A total of 112 patients, average age(22.87±12.21) months; 66 males and 46 females; weight( 9.94±4.08)kg; 3 cases died, 1 case died of sepsis caused by pulmonary infection, 1 case died of low cardiac output syndrome, and 1 case died of multiple organ failure. 62 cases(55.8%) did not transannular patch, 50 cases(44.2%) transannular patch. The pulmonary annulus Z-score, main pulmonary artery Z-score and PAI in TAP group were smaller than those in no TAP group( P<0.05). Receiver operator curves( ROC) analysis showed that the cut-off value of PAI at 0.53 AUC was 0.85, the sensitivity was 75%, the specificity was 80%; the cutoff value of pulmonary annulus at -1.98 AUC was 0.88, the sensitivity was 80%, the specificity was 71%; the cutoff value of main pulmonary artery at -2.12 AUC was 0.87, the sensitivity was 77%, and the specificity was 87%. When the critical value of PAI(>0.53) and main pulmonary artery Z-score(>2.12), 88.2% of the children could avoid TAP, and 94% of the children could avoid TAP when the critical value of pulmonary annulus Z-score(> -1.91) and main pulmonary artery Z-score(>-2.12) were combined. Conclusion:The predictive effect of pulmonary annulus index as a simple and effective predictor of TAP in TOF radical operation is the same as that of pulmonary annulus Z-score. Combining either with main pulmonary artery Z-score was the most accurate method of prediction.
ABSTRACT
Objective:To monitor and investigate the long-term growth trend and nutritional status of very preterm infants (VPIs, born at gestational age between [28~31 +] weeks) with extrauterine growth restriction (EUGR) from birth to preschool period. Methods:VPIs who met with the following criteria were enrolled: infants born in Huai'an Maternity and Child Heath Care Hospital from January 1 to December 31, 2015; infants admitted to the Neonatal Medical Center and discharged alive; infants who received multi-disciplinary treatment in Child Care Division from discharge to preschool period. All of the VPIs were divided into the EUGR group and the non-EUGR group according to whether the weight at hospital discharge was below the 10 th percentile for corrected age in body weight. The weight for age Z score (WAZ), height for age Z score (HAZ), and head circumference for age Z score (HCZ) were calculated at each specified time point (at 40 weeks of age; at 1, 2, 3, 4, 5, 6 and 24 months of corrected age; and at 48 months of age). The growth trend and the nutritional status at 48 months of age were compared between the two groups. Results:1. A total of 53 VPIs were enrolled, among whom 35 cases were boys and 20 cases were with EUGR. The differences in the gestational age, birth weight, incidence of very low birth weight infants, neonatal respiratory distress syndrome (NRDS) and bronchopulmonary dysplasia (BPD) were all statistically significant between the EUGR group and the control group ( x 2= 2.306, 3.543, 10.852, 9.515, 0.001, respectively; all P<0.05). 2. The WAZ and HAZ of the EUGR group were lower at each time point. The WAZ at 40 weeks of age and the HAZ at 3 months of corrected age were significantly different between the two groups. From 40 weeks of age to 2 months of corrected age and from 6 months to 24 months of corrected age, the WAZ, HAZ and HCZ in both groups showed an increasing trend. However, the WAZ in the EUGR group and the WAZ, HAZ and HCZ in the non-EUGR group showed a declining trend from 24 months of corrected age to 48 months of age. 3. There was no significant differences in growth restriction incidence at each time point between the EUGR group and the control group. 4. The nutritional status showed no significant difference between the two groups, either ( P>0.05). Conclusions:Low gestational age, low birth weight, NRDS and BPD are the risk factors of EUGR. The growth trend of the EUGR VPIs shows an overall upward trend from hospital discharge to 24 months of corrected age but declined thereafter, while the nutritional status is good at 48 months of age. Thus, in addition to the integrated management, continuous monitoring of long-term growth and nutrient input after 24 months of age is required for VPIs.

ABSTRACT
OBJECTIVE@#To study the difference in age estimation based on quantitative analysis of DNA methylation by MassARRAY and pyrosequencing techniques.@*METHODS@#The methylation levels of 9 CpG sites from two independent whole blood sample sets (containing 65 and 62 samples) were detected using MassARRAY and pyrosequencing techniques. Z-score transformation was used to remove the batch effects of different techniques, and a linear regression model was used for age prediction.@*RESULTS@#For age prediction using the MassARRAY system, the 65 samples showed a mean absolute difference (MAD) of 2.49 years before Z-score transformation of the data and 2.44 years after the transformation, similar to the results in the 62 samples (MAD of 3.36 years before and 3.42 years after Z-score transformation). For data typed from pyrosequencing, the 65 samples showed a MAD of 4.20 years before and 2.76 years after data Z-score transformation, also similar to the results in the 62 samples (MAD of 3.92 years before and 3.63 years after data transformation).@*CONCLUSIONS@#Z-score transformation can effectively reduce the system batch effect between MassARRAY and pyrosequencing. Data from the MassARRAY system allows direct age estimation without further data processing, while the pyrosequencing data may increase the error in age estimation, which can be corrected by Z-score transformation of the data.

OBJECTIVE: To analyze the influence of noise measuring skills by continuous inter-laboratory comparison among occupational hygiene technical service organizations. METHODS: The results of 68, 55 and 50 occupational hygiene technical service organizations(reference organizations) participating in the inter-laboratory comparison of workplace noise measurement in 2014, 2017 and 2018 respectively were collected. The measurement operation and the calculation of equivalent sound level were evaluated according to the GBZ/T 189.8-2007 Measurement of Physical Agents in Workplace--Part 8: Noise.The measured results were analyzed by z score evaluation method. RESULTS: The results of noise measurement field operation of the reference organizations in the year 2014, 2017 and 2018 show that the accuracy rates of instrument setting was 89.7%, 98.2% and 100.0%, the accuracy rates of measuring position were 52.9%, 81.8% and 94.0%, the accuracy rates of sound level meter holding were 54.4%, 80.0% and 92.0%, the accuracy rates of microphone pointing were 98.5%, 98.2% and 94.0%, and the accuracy rates of noise type recognition were 83.8%, 92.7% and 84.0%, respectively. Among them, the accuracy of instrument setting, measurement position and sound level meter holding showed an increasing trend year by year(P<0.01). The pass rates of measurement results were 91.2%, 94.5% and 88.0% in 2014, 2017 and 2018 respectively. The pass rates of equivalent sound level calculation were 73.5%, 92.7% and 88.0%. The pass rates of comprehensive evaluation were 70.6%, 89.1% and 80.0% respectively. Among them, the pass rates of equivalent sound level calculation and comprehensive evaluation in 2017 were higher than that in 2014(P<0.017). There was no significant difference in the three-year comprehensive assessment total pass rate between private organizations and non-private organizations(84.0 % vs 75.5%, P>0.05). There was no significant difference in the total pass rate of three-year comprehensive evaluation between non-Pearl-River-Delta organizations and Pearl-River-Delta organizations(70.3% vs 81.6%, P>0.05). CONCLUSION: Continuous inter-laboratory comparison in occupational hygiene technical service organizations is beneficial to improve on-site noise measure capability.
ABSTRACT
Background: Overweight and obesity are important modifiable risk factors for various noncommunicable diseases. The link between obesity, poor health outcomes, and all-cause mortality is well established. Overweight and obesity during childhood increases the likelihood of diabetes, hypertension, coronary heart disease, stroke, certain cancers, obstructive sleep apnea, and osteoarthritis more early in younger age groups. Objectives: The aim of the study was to estimate the prevalence and some correlates of overweight and obesity in the study population. Methods: The present study was a cross-sectional study conducted during October 2017 among 300 boys of primary public schools from Baish City of Jazan Province, Saudi Arabia. A semi-structured questionnaire was used for data collection. Weight and height were measured using standard tools. The WHO Z-score reference values of body mass index-for-age were used for the screening of overweight and obesity. Analysis was done using the Statistical Package for the Social Sciences (SPSS version 19.0). Results: The prevalence of overweight and obesity was 10.1% and 12.4%, respectively, among the study participants. There was a significant difference in the overweight and obesity between urban and rural study population. Overweight and obesity was found higher among children who took frequently junk food. Conclusions: Overweight and obesity was substantially prevalent among primary schoolboys with a significant rural–urban difference.
ABSTRACT
Background: Undernutrition continues to be the primary cause of ill health and premature mortality. The sustainable development goal 2 aims to end all forms of hunger by 2030 and lead towards an improvement in child health. The national data categorize the level of undernutrition as underweight, wasting and stunting. The weight for age estimates used under ICDS misses out the other forms of malnutrition. This study was conducted to assess the prevalence of undernutrition using a composite index of anthropometric failure (CIAF) and compare it with conventional indices.Methods: A community based setting and cross-sectional study design. By simple random sampling 265 under-five children residing in a marginalized community of North West district of Delhi. Interviewer administered questionnaire was used to collect information and anthropometric measurements were taken using standard operative procedures. Z scores were calculated by WHO-ANTHRO software version 3.2.2. Descriptive analysis was conducted using statistical package for social sciences version 22.Results: The prevalence of anthropometric failure by CIAF was 60.5% and based on other indices undernutrition was found as 44.5% stunting, 35.4% underweight and 26.4% wasting. MUAC detected 23.7% of undernourished. CIAF provides a better picture of undernutrition compared to other indices.Conclusions: Since CIAF is more than that estimated by any of the conventional indicators, it proves to be a better indicator in assessing the overall burden of under-nutrition in a population. Development of policies based on CIAF to reduce the burden of undernutrition may prove to be more effective.
ABSTRACT
Background: In clinical settings, wasting in childhood has primarily been assessed with the use of a weight-for-height z score (WHZ), and in community settings, it has been assessed via the mid upper arm circumference (MUAC) with a cutoff <115mm for severe wasting and 115-125mm for moderate wasting. Our recent experience indicates that many wasted children were not identified when these cutoffs for MUAC were used.Methods: Authors determined the cutoffs for MUAC to detect wasting in Indian children aged 6-60 mo. A secondary analysis was carried out on data from 1446 children aged 6-59 mo. The area under the receiver operating curve was used to indicate the most appropriate choice for cutoffs that related MUAC with WHZ. The MUAC measurement of each subject was taken using standard technique. Following the World Health Organization (WHO) age and sex-specific cut-off points, nutritional status of children was determined.Results: The mean'SD age for the entire group was 19.8'13.6 mo, MUAC was 132'13mm, and 45% of subjects were girls. Age-stratified analyses revealed that, for ages 6-24 mo, MUAC cutoffs were <120mm for a WHZ <-3 and <125mm for a WHZ <-2 with a sensitivity of 68.3% and 64.7%, respectively, and a specificity of 82.6% and 83.4%, respectively; for ages 25-60 mo, MUAC cutoffs were <135mm for a WHZ <-3 and <140mm for a WHZ <-2 with a sensitivity of 63.7% and 65.4%, respectively, and a specificity of 81.6% and 78.3%, respectively.Conclusions: The respective cutoffs for MUAC to better capture the vulnerability and risk of severe (WHZ <-3) and moderate (WHZ <-2) wasting would be <120 and <125mm for ages 6-24 mo, <135 and <140mm for ages 37-60 mo.
