 The measurement of various components of infant growth is not only essential for monitoring infant health but is also associated with the well-being of infants and their parents, the use of human resources, frequent repositioning of infants, and a considerable amount of time.

 Therefore, the present study aimed to design and evaluate a device for the “simultaneous measurement of infants’ weight, height, head circumference, temperature, and heart rate”.

 This study follows a quantitative and semi-experimental approach. The “simultaneous measurement of weight, height, head circumference, temperature, and heart rate of a child” device was officially registered as an invention with the number 104232 on May 18, 2021. The sample for this study comprised 100 infants selected from hospitals affiliated with Shahid Beheshti University of Medical Sciences, Tehran, Iran. The data related to all 100 infants were collected and recorded using both routine measurement methods and digital devices. Data collection tools included the Wong-Baker Faces scale to assess infant distress and a demographic questionnaire for recording growth components and the time of measurement. Data analysis was conducted using SPSS software (version 20), and statistical significance was determined using the t-test (P < 0.05).

 The comparison of mean distress scores in both the control and intervention groups revealed a significant reduction in infant distress scores during all measurements except for weight (P < 0.05). It is worth noting that the number of infant repositions required for each measurement was reduced from 6 in the routine method to 2 with the digital device. Additionally, although 2 or 3 staff members were needed for measurements in the control group, only 1 staff member was sufficient for measurements in the intervention group.

 Based on the evaluation results of the digital device, it is anticipated that this device could serve as a suitable alternative to the routine methods of measuring infant growth components. However, further studies are warranted to explore the broader applications of this digital device.

The World Health Organization has introduced two sets of child growth standards for growth assessment. These reference values may not be suitable for use in other populations. Therefore, this study aimed to determine specific Z scores in the population covered by Mashhad University of Medical Sciences in Iran.

This cross-sectional study was conducted on data obtained from the evaluation of height, weight, and head circumference of children aged from 0 to 18 months visiting the healthcare centers of Mashhad University of Medical Sciences from March 2018 to March 2021. A total data of 128,472 children were extracted from the Electronic Health Records (SinaEHR®) and included in the study. Finally, the collected data were analyzed using Minitab and SPSS software (version 16).  

The L, M, and S parameters were used to calculate Z scores for weight, height, and head circumference. These Z scores were then compared to standard deviation values ​for each age from our study and international standards to determine any differences. Our study found that mean weight scores were 0.16 kg higher than the CDC standard and 0.34 kg higher than the WHO growth standard.  

The provision of this exclusive reference to children's growth indicators not only allows for a more accurate evaluation but also provides the possibility of comparison with other populations using their specific growth charts. It seems that one of the best plans is to compare growth charts with international populations and national growth charts, which due to the electronization of the entire processes of the health system, is more possible than ever.

The purpose of this study was to investigate the association between age at menarche (AAM) and anthropometric parameters in young female students in Shahrekord, southwest Iran.

A cross-sectional study was conducted in elementary and senior girls’ schools in Shahrekord in 2018. The sampling method was multistage cluster sampling. The 633 students were studied out of 4868 students selected before the commencement of the study. The statistical analysis was done with a one-way analysis of variance, Spearman’s correlation coefficient, and the Kaplan-Meier estimate. The checklist was used to collect the participants’ information. All analyses were conducted using SPSS version 24 (IBM Corp, Armonk, NY, USA).

The average AAM of our participants was 13.34±0.95 years. Only 8.5% of the 633 participants had reached menarche before the age of 12. In this study, the association between AAM and height (P<0.001) and weight (P=0.007) were significant, while there was no relationship between AAM and body mass index (P=0.91).

This study found that the average AAM was like that found in other studies in Iran and other regions of the world. Furthermore, efficient puberty health education is required for female students, especially those aged 12 years.

There is an association between treatment options and growth in patients with mucopolysaccharidoses (MPS). The appropriate management of MPS is an essential factor for the growth of the patients.

This study aims to review systematically the available data on the growth status and related treatment factors in patients with MPS type I and MPS type II.

A systematic literature search was performed in PubMed, Scopus, and the Web of Science using related keywords by March 2023. In this systematic review, the primary outcome was determining the growth status (mainly height z-score) of patients with MPSI and MPSII from reviewed studies and its association with different treatment options. The author’s name, year of publication, country, type of MPS, growth status, treatment options, and any associations between growth status, disease, and treatment variables in the article were extracted. 

From the initially retrieved 743 references, 100 were removed due to being duplicates, 31 articles were evaluated by reading the full text, and finally 20 were included in the systematic review. Based on the analyses, treatment options improved growth in the MPS patients. Certain variables regarding the treatment were key factors, such as the age of treatment initiation, combination therapy, and human growth hormone therapy. Some factors related to the characteristics of the patients, including genotype (type of mutation) and disease severity, are also key factors. Patients with MPSI and MPSII had normal growth and height during the first years of life, but after 2-5 years, their growth rate decreases progressively.

The findings of this review indicated that growth impairment is common in patients with MPSI and MPSII. Treatment improved the growth development in these patients but not as much as expected. Some patients’ characteristics, such as disease severity and type of mutations, affect treatment efficacy and height gain. From treatment-related factors, the most important factor is the age of treatment initiation. Regarding other factors such as donor type, human growth hormone administration, and combination therapies, current findings are inconclusive, and more studies are needed.

This study aimed to assess whether weight gain predicts the outcome of childhood leukemia.

This is a cohort study on patients with leukemia aged 2 to 19 years. Data was gathered by a form consisting of age, sex, baseline and final weight, height, Body Mass Index (BMI), and poor outcome (mortality plus occurrence). We used the Receiver Operator Characteristic (ROC) curve and the Area under the Curve (AUC) to define the cut-off points. Data analysis was performed in SPSS software version 19.

114 patients enrolled in the study, including 68 (59.6%) boys and 46 (40.4%) girls. Ten patients (8.7%) died, and 14 (12.2%) experienced a recurrence. Overall, 16 (14.1%) patients had poor outcomes. In this study, most patients had annual weight gain (95.6%), and all had height gain. AUC of weight and height gain at the diagnosis and the end regarding poor outcome were 0.672 and 0.718, respectively. The cut-off points of weight and height gain for poor outcomes were 1.2 % per month (14.5% annual weight gain, and 0.32 % per month (3.8% annual height gain), respectively. Besides, 60% of patients with weight loss had poor outcomes, and the results revealed that weight loss of more than 12% per year causes poor outcomes.

According to the results, weight and height gain during the treatment period can be related to a better outcome in children and adolescents with leukemia, irrespective of weight, height, and BMI at the diagnosis. Therefore, anthropometric indices may be associated with outcomes

 Zinc and vitamin D are essential factors required for growth. Recently, studies have shown a possible link between serum zinc and vitamin D levels.

 This study was designed to evaluate this link and its possible affecting growth factors in children and adolescents in Iran.

 This cross-sectional study was performed on the data obtained from children aged 2 to 18 years old referring to a growth assessment clinic for routine growth follow-ups in the city of Shiraz from April to August 2019. A total of 454 children who were checked for 25-hydroxyvitamin D and zinc simultaneously were included.

 Vitamin D was negatively correlated with body mass index (BMI) z-scores, while zinc was positively correlated with vitamin D and height z-scores. Subjects with vitamin D levels ≤ 8.6 ng/mL were 2.081 times as likely to have a zinc deficiency. Vitamin D insufficiency was significantly higher in overweight and obese children. Mean vitamin D and zinc levels were significantly lower, and vitamin D insufficiency was significantly higher in boys than girls. While mean zinc levels were significantly lower in short children, the prevalence of zinc deficiency was not statistically different between short and normal height statures.

 Very low vitamin D levels are likely to be accompanied by zinc deficiency, possibly caused by malnutrition and the modulatory effect of serum vitamin D on zinc absorption. Unlike zinc deficiency, vitamin D insufficiency is much more prevalent in Iranian children than in children from other countries. Vitamin D and zinc are associated with BMI and height z-scores, respectively.

Changes in blood pressure are of special importance in ensuring children's health. Various factors affect blood pressure in them. The aim of this study was to determine the factors affecting blood pressure in children and adolescents.

In this descriptive cross-sectional study, 1282 students aged 7 to 12 years were studied by cluster and random sampling methods from 49 schools in Kashmar city, Iran. After measuring blood pressure, weight, pulse rate, height, and BMI and collecting demographic and medical information of the research samples, the obtained data were evaluated in SPSS software ver. 21 using analysis of variance test.

Five hundred thirty-six boys and 746 girls participated in this study. Gender had an effect on diastolic and systolic blood pressure at all ages from 7 to 12 years (p=0.0001). The height, pulse rate, weight and BMI had an effect on blood pressure; although there was no significant relationship between height and systolic and diastolic blood pressure at the age of 7 years (p=0.379) and no significant relationship between height and systolic blood pressure at the age of 12 (p=0.239). Family history of high blood pressure had an effect on diastolic blood pressure only at the age of 8 (p=0.028).

Factors such as gender, weight, pulse rate, height, BMI and family history of hypertension were effective on blood pressure of children and adolescents. Considering the differences between the results of this research and other studies, their use in the field of regional prevention of high blood pressure is recommended.

Due to chronic respiratory and gastrointestinal problems, growth failure is a common issue in patients with cystic fibrosis (CF). The present study aimed to investigate the prevalence of growth hormone deficiency (GHD) in CF children with stable gastrointestinal and respiratory conditions.

In this study, the growth indicators of all 4–16‑year‑old children referred to two CF clinics were monitored over 3 years. Children without severe gastrointestinal or pulmonary symptoms with weight <3% percentile or whose height increase were two standard deviations below their expected height growth over 6 months were selected for the growth hormone (GH) stimulation test by clonidine and L‑dopa test. Some of the children without CF, who were also referred for height growth disorders and matched the CF group, were considered the control group. They underwent the GH stimulation test, and the results were compared.

From 150 patients with CF, growth failure was observed in 24 patients with stable gastrointestinal and respiratory conditions; in 10 of them, the GH stimulation test was deficient. The prevalence of GHD was 6.6% in CF patients. In the control group of 30 children without CF, but with growth failure, the GH was deficient in nine cases, implying no significant difference with the case group (P = 0.37).

In our study, the prevalence of GHD was 6.6% in CF patients, whereas the prevalence GHD in the normal population of childhood is <1%. Therefore, further studies should be designed to investigate the cause of GHD in CF patients.

Identification of victims is one of the main challenges of forensic medicine. Height is one of the key measurements of the biological profiles of individuals. This study aimed to evaluate height based on measuring three-dimensional CT scan indices of twelfth thoracic (T12), first lumbar (L1), and fifth lumbar (L5) vertebrae in Iranian adults.

The present study was a cross-sectional study performed on 100 patients who underwent a spinal CT scan. Vertebral T12, L1, and L5 indices were measured in these individuals. Finally, the evaluated indices were statistically compared and the diagnostic effect of each was evaluated to estimate the height. Independent t-test and linear regression were used using SPSS software v. 21. A P value less than 0.05 was considered significant.

The results showed that the mean difference between T12, L1, and L5 indices in the two groups of male and female patients was statistically significant. With one unit increase in the Transverse process distance T 12 (TDM T12), there is an increase of 0.42 units in height (P=0.02).

According to the results of the present study, the measurements of the T12, L1, and L5 vertebral indices have a significant relationship with gender. Among the measurements of the T12, L1, and L5 vertebral indices, just TDM T12 can be a predictive factor to estimate the height of the Iranian population

Various kinematics and kinetics methods have been proposed for the assessment of jumping ability as a critical skill in professional volleyball players, but little is known about the accuracy and differences between these methods. Therefore, the objective of the current study was to answer the question “Is there any difference between the results of various kinetic methods in the assessment of block jump height in volleyball players or not?” 

Twenty-one healthy male junior volleyball players of the Iran national team performed the block jump task on a force platform. Three common formulas mostly used in literature based on kinetics output of force platform were selected for the comparison of resultant jump height. Descriptive analysis, Shapiro-Wilk test, and ANOVA were used for statistical calculations (p<0.05).

The results showed no significant difference between the means of block jump heights measured based on different kinetic methods in volleyball players.

Formula calculation methods are very valid for measuring the jump height of the block jump and lead to very similar results for estimating jump height and are also replaceable with each other.

Nephrotic syndrome is a clinical manifestation of glomerular  disease characterized by severe or nephrotic-range proteinuria >3.5 g/24 hours. The treatment of nephrotic syndrome using corticosteroid especially prednisone, belongs to a class of glucocorticoid. Glucocorticoids are proven  to be  able to inhibit growth through several mechanisms.  The objective of this study  was  to  analyze  the  characteristic  of  height  in  childhood  nephrotic syndrome  and  analyze  the  correlation  between corticosteroid therapy and height in childhood nephrotic syndrome.

 This systematic review was conducted using the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA)  guideline.  The  literature  search  was  conducted  in  November  2020  in  four  databases:  PubMed,  Science  Direct, Scopus, and DOAJ. Quality assessment was carried out using a quality assessment tool for quantitative studies from EPHPP.

Six studies met the inclusion criteria for final analysis.  The mean final height z-scores were -0.66 ± 3.04. The height z-scores of Steroid-Dependent Nephrotic Syndrome (SDNS) (-0.33 ± 0.87) and Steroid-Resistant Nephrotic Syndrome (SRNS) (-0.97  ±  1.34)  patients  were  lower  than  Steroid-Sensitive  Nephrotic  Syndrome  (SSNS)  (-0.20  ±  3.14)  patients.  The height  zscores of nephrotic syndrome children were significantly lower than a normal population.  Five studies suggested that there is a correlation  between  corticosteroid  therapy  and  height  on  childhood  nephrotic syndrome  and  one  study  did  not  find  a correlation between them.

 According  to  findings,  there  is  a  negative  correlation  between  corticosteroid  therapy  and  height  in childhood nephrotic syndrome. Nephrotic syndrome children had significantly lower height z-scores than a normal population. The SDNS and  SRNS  patients  are  more  susceptible  to  have  a  lower  height  than  SNSS  patients  as  they  have  a  higher  cumulative corticosteroid dose.

Monitoring and evaluating physical growth in children is an important way to determine their nutritional and health status. Health personnel can diagnose growth impairment and malnutrition in children by growth monitoring from growth indices.

This study aimed to determine the cut-off points of body mass index (BMI) in children and adolescents and compare them with the National Center for Health Statistics (NCHS) standards.

In this cross-sectional study, 4,320 students (6 - 11 years old) were selected by cluster sampling in 24 primary schools. A class (a cluster) was randomly selected from each base in each school. Then, 30 students from each class were randomly selected. The height and weight of students were measured, and then BMI was calculated for students. After data collection, height, weight, and BMI tables were calculated based on age and sex and compared with the WHO standards using the LMSchartmaker Pro software 2.3.

The results showed that height, weight, and BMI percentiles in both gender were close to NCHS standards features in all ages, but some percentiles were higher in children in Yazd than NCHS standardsNCHS standards, including the 97th percentile of height for boys, the 97th percentile of BMI for both gender, the 97th percentile of weight for boys, the 75th percentile of weight for boys aged 9 and 10 years, and the same percentile in girls ages 7 - 11 and 9 - 11 years, respectively.

According to the results, the researchers recommend using the indices of the present study according to the differences observed between height, weight, and BMI in children studied with NCHS standards.

Augmentation of facial components is an acceptable approach in facial aesthetics. The best filler material and the optimal technique for facial soft tissue augmentation still remain to be determined. This study has assessed the lip augmentation using post-auricular fibroareolar tissue as a new autogenous filler.

This prospective study enrolled patients who were candidate for lip augmentation. Loose fibroareolar tissue was harvested from post-auricular region and was inserted in the prepared lip pocket. Standard digital photography was used for lip analysis in each patient before and 6 months after surgery (the height and projection of the upper lip and lower lip).

At a mean follow-up period of 6 months, average upper and lower lip height increased from 5.27 to 8.72 mm (p<0.001), and the average upper and lower lip projection increased from 3.97 to 7.75 mm (p<0.001).

Our technique was minimally invasive and a safe method, in which post-auricular loose fibroareolar tissue was applied for lip augmentation with minimum donor site morbidity and long-term results. On the follow-up, all patients were satisfied with the results and no patients required any revision operation. Moreover, the complication rate was negligible.

The aim of the study was to assess the relationship between height and dental caries among 13‑year‑old adolescents in schools of Bangalore, India.

A cross‑sectional study was undertaken on 1900 schoolchildren aged 13 years from both government and private schools of Bangalore using stratified random sampling. Demographic data; family‑related factors; and general and oral health‑related factors such as frequency of sugar consumption, dietary habits, oral hygiene practices, and dental attendance were interviewed using both open‑ended and close‑ended questions. Anthropometric measurements for height and weight were performed. Clinical examination was done and caries was recorded using the decayed, missing, and filled teeth (DMFT) index (WHO criteria, 1997). Data were analyzed using SPSS version 21.0, and descriptive statistics including percentages, mean, and frequencies were performed. Student’s t‑test and ANOVA were applied to find the significant differences between mean DMFT among groups. Categorical data were analyzed by Chi‑square test for differences between groups. Pearson correlation coefficient was used to find the correlation among dental caries and height and body mass index (BMI). P value was set at a statistical significance level of 0.05.

The prevalence of dental caries among the study population was 36.3% which was higher among girls as compared to boys. Dental caries was found to be significantly associated with socioeconomic status, family structure, birth order, use of oral hygiene aids, mouthrinsing, last dental visit, weight, and BMI. Height and BMI showed a strong negative correlation with dental caries.

The present study showed a significant negative correlation between height and dental caries. However, since both caries and height are a dynamic phenomenon, hence a longitudinal study exploring the possible relationship should be considered.

Measuring children's and adolescents’ height and weight are among the most important information sources and the best index forthe assessment of individual growth status and community’s nutrition and health status. Regular measurements of height and weight and recordingthe data on proper curves lead to the timely identification of growth disorders. The present study aimed at determining the average height, weight,and body mass index of 6-18-year-old boys and girls in Jiroft Town and comparing the results with the National Center for Health Statistics (NCHS). In this study, the values for height, weight, and body mass index of 5850 children aged between 6 and 18 were examined in a stratifiedrandom fashion. Growth percentile curves for height, weight, and body mass index were plotted by Microsoft Excel Software. In comparison to the NCHS height and weight percentiles, the data of the present study showed lower values for the studied children.The comparison of BMI percentiles of boys and girls with NCHS percentiles for each age proved that until the age of 8, the BMI percentiles are fitto NCHS percentiles. This is while in older ages, the calculated BMI percentiles of males and females were remarkably lower than NCHSpercentiles. Based on the results, it is generally concluded that using foreign criteria leads to a false diagnosis of underweight or shortness in somechildren and it is recommended to apply native and country-level percentiles for the examination of children’s growth.

The aim of this study was to find the prevalence of chronic hypertension and prehypertension conditions among children.

In this cross-sectional study, a total of 1017 students in Kerman schools were examined during a period from 2013 to 2014. The weight, height, body mass index (BMI), systolic and diastolic blood pressure and family history of high blood pressure were obtained. Pediatric Hypertension was defined as a mean systolic or diastolic reading (or both) ≥ 95th percentile and prehypertension was defined as the blood pressure reading between the 90th and 95th percentiles of the predicted values based on gender, age and height.

According to the results, the prevalence of prehypertension and hypertension in schoolchildren was 1.9% and 3%, respectively. According to BMI, 13.7% of children were overweight and 14.3% were obese. There was a positive association between BMI and the development of hypertension.

Our findings demonstrated that approximately 3% of schoolchildren were afflicted with hypertension. Hypertension showed a positive association with overweight and obesity.

Herbal medicine may have irreparable effects on fetal development. This study investigated the effect of Cariandrumsativum (coriander) aquous extract on mice fetal height and weight. In an experimental study, 120 pregnant mice were divided into four equal groups. The control group was without any intervention. The experimental group received 3500, 5000 and 6500 mg/kg of aquous extract of coriander. The height and weight of the embryos were recorded in first, second and third week of pregnancy. The height and weight of embryos in experimental groups in first, second and third week was significantly lower than the control group.  Coriander (C. Sativum) aquous extract was shown to reduce the fetal height and weight in a dose-dependent manner. These findings can be added to the literature when coriander is going to be used during pregnancy.
