Assessment of upper to lower body segment ratio and arm span to height difference in school children of Lahore.

Objective: To assess upper-to-lower body segment ratio and arm span to height difference in children. METHODS: The descriptive, cross-sectional study was conducted in schools of the Raiwind area near Lahore, Pakistan, from November 2021 to May 2022, after approval from the ethics review committee of the Sharif Medical and Dental College, Lahore. The sample comprised children aged 3-14 years whose height fell between the 3rd and 97th centiles on the Centers for Disease Control and Prevention height-for-age chart. Data was analysed using SPSS 23. RESULTS: Of the 1,836 children, 906(49.3%) were boys with mean age 8.45±3.02 years, mean height 132.54±17.78cm and mean weight 32.0±13.72kg. Besides, there were 930(50.7%) girls with mean age 8.26±3.21 years, mean height 130.41±18.03cm and mean weight 31.09±13.88kg. The mean upper-to-lower body segment ratio in boys was 1.06±0.15 at age 3 years, 0.96±0.08 at age 7 and 0.94±0.08 at age 10. The mean upper-to-lower body segment ratio in girls was 1.08±0.08 at age 3 years, 0.98±0.07 at age 7, and 0.92±0.10 at age 10. The mean arm span to height difference in boys was -1.81±5.83 and in girls -4.09±5.77. Conclusion: Upper-to-lower body segment ratio and arm span to height difference may help paediatricians in the evaluation of disproportionate short stature.

Correlation between anthropometric measurements of height and arm span in Indonesian children aged 7-12 years: a cross-sectional study.

BACKGROUND: Height is an anthropometric measurement that serves as the most constant indicator of growth. In certain circumstances, arm span can be used as an alternative to height measurements. This study aims to analyze the correlation between anthropometric measurements of height and arm span in children aged 7-12 years. METHODS: A cross-sectional study was carried out from September to December 2019 in six elementary schools in Bandung. Children aged 7-12 years were recruited with a multistage cluster random sampling method. Children with scoliosis, contractures, and stunting were excluded from the study. Height and arm span were measured by two pediatricians. RESULTS: A total of 1,114 children, comprising 596 boys and 518 girls, fulfilled the inclusion criteria. The ratio of height to arm span was 0.98-1.01. The regression equation used to predict height through measurement of arm span in male subjects was Height = 21.8623 + 0.7634 x Arm span (cm) + 0.0791 x age (month); R2 = 94%; standard error of estimate (SEE): 2.66 and that in female subjects was Height = 21.2395 + 0.7779 x Arm span (cm) + 0.0701 x age (month); R2 = 95.4%; SEE: 2.39. The predicted height and the average actual height were not significantly different. There is a strong correlation between height and arm span in children aged 7-12 years. CONCLUSIONS: Arm span can be used to predict the actual height of children aged 7-12 years and as an alternative measurement for growth.

Relationship between arm span to height ratio, aortic root diameter, and systolic blood pressure in collegiate athletes.

Study objective: Sudden cardiac death is the most common cause of non-traumatic death in collegiate athletes. Marfan syndrome poses a risk for sudden cardiac death secondary to aortic root dilation leading to aortic dissection or rupture. Arm span to height ratio (ASHR) > 1.05 has been proposed as a screening tool for Marfan syndrome in pre-participation examinations (PPE) for collegiate athletes but limited data exists on the association between ASHR and aortic root diameter (ARD). This study examines the relationship between ASHR and ARD and assesses for predictors of ARD. Design: Retrospective chart review. Setting: National Collegiate Athletic Association Division I University. Participants: 793 athletes across thirteen sports between 2012 and 2022 evaluated with PPE and screening echocardiogram. Interventions: Not applicable. Main outcome measures: (1) Relationships between ASHR, SBP, BSA, and ARD amongst all athletes as well as stratified by ASHR >1.05 or ≤1.05 using univariate analysis. (2) Predictors of ARD using multivariate analysis using linear regression. Results: 143 athletes (18 %) had ASHRs > 1.05. Athletes with ASHR > 1.05 had higher ARD (2.99 cm) than athletes with ASHR ≤ 1.05 (2.85 cm). Weak correlations were noted between ASHR, ARD, and SBP. Multivariate analysis showed that BSA, male sex, and participation in swimming were predictors of ARD. ASHR was not predictive of ARD in regression analysis. Conclusions: These findings showed a tendency towards higher ARD in athletes with ASHR >1.05 but this observation was not statistically significant in multivariate analysis.

Clinical and laboratory differences between chromosomal and undefined causes of non-obstructive azoospermia: A retrospective study

ABSTRACT BACKGROUND: Knowledge of clinical and laboratory differences between chromosomal and undefined causes aids etiological research on non-obstructive azoospermia. OBJECTIVE: Compare clinical and laboratory differences between men with non-obstructive azoospermia due to chromosomal anomalies versus undefined causes DESIGN AND SETTING: A cross-sectional retrospective study conducted at a public university hospital in Campinas (Brazil) METHODS: All men aged 20-40 years with non-obstructive azoospermia were included in the analysis. RESULTS: The 107 cases included 14 with Klinefelter syndrome (KS) (13%), 1 with mosaic KS, 4 with sex development disorders (2 testicular XX, 1 NR5A1 gene mutation, and 1 mild androgen insensitivity syndrome) (4%), 9 with other non-obstructive azoospermia etiologies (8%), and 79 with undefined causes. The 22 chromosomal anomaly cases (14 KS, 1 mosaic KS, 2 testicular XX, 4 sex chromosome anomalies, and 1 autosomal anomaly) were compared with the 79 undefined cause cases. The KS group had lower average testicular volume, shorter penile length, and lower total testosterone levels but greater height, arm span, serum luteinizing hormone (LH) and follicle stimulating hormone (FSH) levels, and gynecomastia frequency (absent in the undefined group and affecting more than half of the KS group). Patients with testicular XX DSD had LH, FSH, and penile length data intermediate between the KS and undefined cause groups, testicular volume similar to the KS group, and other data similar to the undefined group. CONCLUSION: Clinical and laboratory data differentiate men with non-obstructive azoospermia and chromosomal anomalies, particularly KS and testicular XX, from those with undefined causes or other chromosomal anomalies.

Estimation of Stature from Arm Span, Arm Length and Tibial Length among Adolescents of Aged 15-18 in Addis Ababa, Ethiopia.

BACKGROUND: Knowing the relationship between stature and different anatomical anthropometric parameters help forensic scientists, anatomists and clinicians to estimate standing height from mutilated remains of body parts in clinical practices and forensic investigations. It is a necessity when measuring height is unenviable due to certain medical conditions and in field studies. This study aims to estimate stature from arm span, arm length and tibial length among adolescents of age 15-18 in Ethiopia. METHODS: A school based cross-sectional study was carried out among 416 high school students in Addis Ababa, Ethiopia from May to June 2019. Stratified multi-stage sampling techniques were used to select the study participants. Anthropometric measurement including weight, height, arm span, arm length and tibial length was measured. Data entry was done by Epi-Data a version 4.4.3.1 and data analysis was carried out by Statistical Package for Social Sciences version 23. Regression models and multiplication factors were generated for estimation of height from anthropometric parameters. RESULT: From total participants 51.4% were females and 48.6% were males. The mean height of study participants was 164.36±8.89cm for males and 155.75±5.86cm for females. The correlation coefficients(R) of anatomical anthropometric measurements with height were: arm span (males R=0.843, females R=0.708), arm length (males R=0.806, females R=0.635), and tibial length (males R=0.738, females R=0.611). CONCLUSION: Stature predicted from arm span, arm length, and tibial length is a valid indicator of height. Arm span was appeared to be the best predictor of stature.

Predicted Reference Equations for Spirometry Indices as a Proxy from Anthropometry Measurements of Nigerian Children with Sickle Cell Anaemia Aged 5-12 Years.

BACKGROUND: Significant morbidity and mortality in patients with sickle cell disease are accounted for by lung complications. To facilitate good respiratory care for children with sickle cell anaemia the generation of local predicted values is highly important. OBJECTIVE: To determine the reference equations for spirometry indices estimation in children with sickle cell anaemia, which can be readily used as proxy when there is no easy accessibility to spirometer. METHODS: A cross-sectional study with linear regression models developed to estimate reference values for spirometric indices in Nigerian children with sickle cell anaemia aged 5-12 years. RESULTS: Age as independent variables for estimation of forced expiratory volume in 1 s (FEV1) was associated with lowest coefficient of determination (R2) and highest standard error. The coefficient of determination (R2) and standard error was highest and lowest, respectively, when arm span was used to determine peak expiratory flow rate (PEFR). Prediction models for PEFR and FEV1 gave the closest mean estimates that were 0.18 and 0.16 lower and higher than the actual mean PEFR and FEV1, respectively, but the differences was significant only in FEV1. On the contrary the prediction models for forced vital capacity (FVC) gave mean estimates that was 1.02 higher than the actual mean FVC, however, the finding was not significant. CONCLUSION: Preferred proxy for spirometry indices in children with sickle cell anaemia may be arm span.

Relationship between Anthropometric Parameters and Throwing Speed in Amateur Male Handball Players at Different Ages.

The objectives of this study were: (i) to analyse anthropometric parameters and throwing speed from seven meters in amateur male handball players of different ages; (ii) to know the relationship between anthropometric parameters and throwing. One hundred seventy-six male handball players (16.5 ± 5.1 years old) participated in the study, classified according to their age: senior (n = 35), U18 (n = 30), U16 (n = 37), U14 (n = 50) and U12 (n = 24). All participants were evaluated by anthropometric measurements (height, weight, body mass index, arm span, hand width) and throwing speed from 7 m standing. A one-way analysis of variance with a Bonferroni post hoc test was used to establish the differences between teams. Pearson's simple correlation coefficients were calculated between analyse anthropometric parameters and throwing speed. Multiple linear regression was used to predict the throwing speed. Only BMI was related with throwing speed in all age groups (0.506 > r < 0.813, p < 0.05). Throwing speed was predicted (24-72%) with only one or two variables in each model. The selected variables were: BMI, arm span in U16 model and height U14 model, and the BMI, arm span and height are proved to be good predictors of TS in male handball players.

Arm Span and Its Relation to Height in a 2- to 17-Year-Old Reference Population and Heterozygous Carriers of ACAN Variants.

BACKGROUND/OBJECTIVES: In the clinical assessment of a short or tall child, estimating body disproportion is useful to assess the likelihood of a primary growth disorder, e.g., skeletal dysplasia. Our objectives were (1) to use data from the Maastricht study on healthy children (2-17 years) to calculate relative arm span (AS) for height (H) to serve as age references for clinical purposes; (2) to assess its age and sex dependency; and (3) to investigate relative AS adjustment for age and sex in individuals with ACAN haploinsufficiency. METHODS: The Maastricht study data (2,595 Caucasian children, 52% boys, 48% girls) were re-analysed to produce reference tables and graphs for age and sex of AS - H and AS/H. Published information on AS/H in Europeans was used as reference data for adults. Relative AS from 33 patients with ACAN haploinsufficiency were plotted against reference data and expressed as standard deviation score (SDS) for age and sex. RESULTS: Mean AS - H from 2 to 17 years increased from -1.2 to +1.5 cm in boys and from -4.8 to +1.6 cm in girls. Mean AS/H increased from 0.9848 to 1.0155 in boys and from 0.9468 to 1.0028 in girls. Mean AS/H in patients with ACAN haploinsufficiency was approximately 1.0, 1.5 and 0.5 SDS in young children, adolescents and 20- to 50-year-olds, respectively, and normal thereafter. CONCLUSIONS: These reference charts can be used for 2- to 17-year-old children/adolescents. Carriers of ACAN haploinsufficiency have an elevated mean AS/H in childhood and adolescence and a slightly elevated ratio till 50 years.

Nationwide stature estimation from armspan measurements in Albanian youngsters / Estimación de estatura a nivel nacional a partir de mediciones de envergadura en jóvenes albaneses

The purpose of this research is to examine stature in both Albanian sexes as well as its association with arm span, as an alternative to estimating stature. A total of 445 individuals (266 boys and 179 girls) participated in this research. The anthropometric measurements were taken according to the protocol of ISAK. The relationships between stature and arm span were determined using simple correlation coefficients at a 95 % confidence interval. Then a linear regression analysis was carried out to examine extent to which arm span can reliably predict stature. Results displayed that Albanian boys are 176.57±7.36 cm tall and have an arm span of 179.98±9.41 cm, while Albanian girls are 166.84±9.28 cm tall and have an arm span of 167.53±10.34 cm. The results have shown that both sexes made Albanians a tall nation but not even close to their male compatriots from Kosovo that are almost 3 centimeters taller, while the results in female population are opposite. Moreover, the arm span reliably predicts stature in both sexes, which confirms a high R-square (%) for the boys (73.4) as well as for the girls (78.8).

El objetivo de esta investigación fue examinar la estatura en individuos de ambos sexos albaneses, además de su asociación con la extensión del brazo, como una alternativa a la estimación de la estatura. Un total de 445 individuos (266 niños y 179 niñas) participaron en esta investigación. Las medidas antropométricas se tomaron de acuerdo con el protocolo de ISAK. Las relaciones entre la estatura y el brazo se determinaron utilizando coeficientes de correlación simples en un intervalo de confianza del 95 %. Luego se realizó un análisis de regresión lineal para examinar en qué medida el brazo puede predecir de manera confiable la estatura. Los resultados muestran que los niños albaneses miden 176,57 ± 7,36 cm de alto y tienen una medida del brazo de 179,98 ± 9,41 cm, mientras que las niñas albanesas miden 166,84 ± 9,28 cm de alto y tienen una medida del brazo de 167,53 ± 10,34 cm. Los resultados han demostrado una altura importante en ambos sexos de la población albanesa. Sin embargo, se observó que respecto de la altura los varones de Kosovo miden casi 3 centímetros más, mientras que en la población femenina se observó lo contrario. Además, la extensión del brazo predice de manera confiable la estatura en ambos sexos, lo que confirma un alto Rcuadrado (%) para los varones (73,4) y para las mujeres (78,8).

Diagnosis of Presarcopenia Using Body Height and Arm Span for Postmenopausal Osteoporosis.

PURPOSE: Sarcopenia and osteoporosis are both serious health problems in postmenopausal women. The Asia Working Group for Sarcopenia recommends using the skeletal muscle index (SMI), which is height-adjusted appendicular skeletal muscle mass (ASMM). However, loss of height has been shown to be a common clinical finding in patients with osteoporosis. This study examined the prevalence of presarcopenia using height and arm span, which is a predictor of height, and investigated the diagnostic accuracy for presarcopenia. METHODS: A total of 55 post-menopausal osteoporotic patients aged 62-95 years underwent bioelectrical impedance analysis (BIA) for ASMM measurement and dual-energy X-ray absorptiometry (DXA) scan for bone mineral density (BMD). Anthropometric measurements, including height, weight, and arm span were taken, and body mass index (BMI), SMI, and arm span-adjusted SMI (Arm span SMI) were calculated. Presarcopenia was defined as SMI or Arm span SMI <5.7 kg/m2 in this study. RESULTS: The prevalence of presarcopenia was 27.3% and 38.2% evaluated by SMI and Arm span SMI, respectively. The prevalence of presarcopenia was higher when evaluated by Arm span SMI than by SMI. In the presarcopenia group diagnosed only by Arm span SMI (n=11), the arm span-height difference was significantly higher (p<0.001) and the percentage of young adult mean (YAM) femoral neck-BMD was significantly lower (p=0.013) compared to the normal group diagnosed by both SMI and Arm span-SMI (n=29). CONCLUSION: These results indicated that Arm span SMI might be useful for the diagnosis of sarcopenia in patients with severe osteoporosis and kyphosis.

Correlation between the arm-span and the standing height among males and females of the Khasi tribal population of Meghalaya state of North-Eastern India.

INTRODUCTION: The estimation of relationship between the arm span and the standing height has been an important tool in anthropometric measurements especially in cases where direct measurement of stature is not possible. OBJECTIVE: To find the relationship between the arm-span and the standing height of both males and females in the population of Khasi tribal population of Meghalaya. MATERIALS AND METHODS: The study involved 400 numbers (272 males and 128 females) of healthy human volunteer subjects belonging to Khasi tribe of Meghalaya. The standing height and arm-span were measured for each individual and analyzed. RESULT: Of the 400 healthy volunteers, 272 (68%) were males and 128 (32%) were females with age ranged from 25 to 45 years. Height and arm span in males (159.68 ± 4.12 cm and 166.30 ± 4.27 cm, respectively) werefound to be significantly (p < 0.001) higher than females (149.96 ± 3.04 cm and 155.77 ± 3.13 cm respectively). The Pearson correlation coefficient (r) between height (cm) and arm span (cm) showed significant positive correlation in both male (r = 0.988, P < 0.001) and female (r = 0.991, P < 0.001) study subjects. The regression equation was Height = 1.060 + 0.954 (Arm span); R2 = 0.976; SEE = 0.646 for male. For female subjects the regression equation was found as Height = 0.150 + 0.962 (Arm span); R2 = 0.983; SEE = 0.400. CONCLUSION: Arm-span can be used as one of the most reliable parameter in both males and females for obtaining the stature of an individual in alternative to the height.

Developing an equation for estimating body height from linear body measurements of Ethiopian adults.

BACKGROUND: Measurements of erect height in older people, hospitalized and bedridden patients, and people with skeletal deformity is difficult. As a result, using body mass index for assessing nutritional status is not valid. Height estimated from linear body measurements such as arm span, knee height, and half arm span was shown to be useful surrogate measures of stature. However, the relationship between linear body measurements and stature varies across populations implying the need for the development of population-specific prediction equation. The objective of this study was to develop a formula that predicts height from arm span, half arm span, and knee height for Ethiopian adults and assess its agreement with measured height. METHODS: A cross-sectional study was conducted from March 15 to April 21, 2016 in Jimma University among a total of 660 (330 females and 330 males) subjects aged 18-40 years. A two-stage sampling procedure was employed to select study participants. Data were collected using interviewer-administered questionnaire and measurement of anthropometric parameters. The data were edited and entered into Epi Data version 3.1 and exported to SPSS for windows version 20 for cleaning and analyses. Linear regression model was fitted to predict height from knee height, half arm span, and arm span. Bland-Altman analysis was employed to see the agreement between actual height and predicted heights. P values < 0.05 was used to declare as statistically significance. RESULTS: On multivariable linear regression analyses after adjusting for age and sex, arm span (ß = 0.63, p < 0.001, R2 = 87%), half arm span (ß = 1.05, p < 0.001, R2 = 83%), and knee height (ß = 1.62, p < 0.001, R2 = 84%) predicted height significantly. The Bland-Altman analyses showed a good agreement between measured height and predicted height using all the three linear body measurements. CONCLUSION: The findings imply that in the context where height cannot be measured, height predicted from arm span, half arm span, and knee height is a valid proxy indicator of height. Arm span was found to be the best predictor of height. The prediction equations can be used to assess the nutritional status of hospitalized and/or bedridden patients, people with skeletal deformity, and elderly population in Ethiopia.

Height Measures: Evaluating Alternatives to Standing Height in the Ambulatory Setting.

BACKGROUND: Height measurement is a key clinical component to measure body mass index and body surface area used for patient care, including calculating chemotherapy doses. Some patients cannot feasibly or safely stand for height measurement because of a number of diseases and disabilities. The literature is unclear regarding alternatives to standing height for patients unable to stand. OBJECTIVES: The purpose of this research study was to test equivalence of a number of measurements to find a reliable alternative to standing height for ambulatory oncology clinic patients who are unable to or cannot safely stand. METHODS: A repeated-measures design was used to measure the height of 60 volunteer adult participants using a convenience sample of 30 men and 30 women. Standing height was compared to self-reported height, recumbent length, arm span, half-arm span, demispan, and knee height measurements. FINDINGS: Results indicated that demispan was equivalent to standing height with a mean difference of -0.69. A practice change to use demispan in patients who cannot stand has been proposed and accepted at the authors' organization. The use of demispan was a feasible alternative to standing height in cost of supply and technique.

Development of body proportions in achondroplasia: Sitting height, leg length, arm span, and foot length.

The aims of this study was to construct references for sitting height, leg length, arm span, relative sitting height (sitting height/height), and foot length and to discuss the development for these anthropometric variables in achondroplasia. Sex-specific references covering ±2 SD are presented for ages 2-20 years. Legs and arms in achondroplasia are already at 2 years of age considerably shorter than in the general population and this deviation increases with age. At adult ages, legs are almost 50% shorter than in the general population and arm span roughly 35% shorter. As sitting height is only mildly affected, relative sitting height position develops far beyond normal ranges. Foot length is also not as affected as limbs.

Relationship between height and arm span of elderly persons in an urban colony of New Delhi.

Anthropometric changes take place with increasing age. Progressive loss of height makes it difficult to use height for calculation of body mass index in nutritional screening of elderly persons. There is a need to find other alternative methods which could be used as proxy measurements of height in them. To assess the relationship of height and arm span and among elderly persons. A community-based cross-sectional study was conducted among elderly persons in urban colony of Delhi. Height and arm span of persons aged 60 years and above (n = 711) were measured according to standard methods. Correlation between arm span and height was calculated. The mean arm span was seen to be more than the mean height in all age-groups and both sexes. There was a linear relationship between height and arm-span in all age-groups. There was a strong correlation between arm span and height in all age groups. Arm span could be used instead of height as an alternative in the conventional body mass index in elderly persons.

The Use of Arm Span as a Substitute for Height in Calculating Body Mass Index (BMI) for Spine Deformity Patients.

OBJECTIVE: To compare arm span and height in body mass index (BMI) calculation in patients with spinal curvature and investigate their impact on interpretation of BMI. STUDY DESIGN: Prospective case-control cohorts. SUMMARY OF BACKGROUND DATA: The BMI value is based on weight to height ratio. Spine deformity patients experience height loss and its use in calculating BMI is likely to produce errors. A surrogate for height should therefore be sought in BMI determination. METHODS: Ninety-three spine deformity patients were matched with 64 normal children. Anthropometric values (height, arm span, and weight) and spinal curve were obtained. BMIs using arm span and height were calculated, and statistical analysis performed to assess the relationship between BMI/height and BMI/arm span in both groups as well as the relationship between these values and Arm Span to Height difference (Delta AH). RESULTS: There were 46 males and 47 females, the average age was 15.5 years in Group 1 versus 33 males and 31 females, average age 14.8 years in Group 2. Major scoliosis in Group 1 averaged 125.7° (21° to 252°). The extreme curves show vertebral transposition, with overlapping segments making it more than 180°. A logistic regression showed that there was linearity in BMI scores (R2 = 0.97) for both arm span and height (R2 = 0.94) in group 2 patients. For group 1 patients there was a significant difference in the BMI values when comparing BMI/arm span versus BMI/height (p < .0001). Mean BMI values using height was overstated by 2.8 (18.6%). The threshold at which BMI score must be calculated using arm span as opposed to the height (Delta AH) was determined to be 3 cm. CONCLUSIONS: Spine deformity patients experience height loss, which can impact their true BMI values thereby giving an erroneous impression of their nutritional status. The arm span should be used in patients with Delta AH >3 cm to properly assess nutritional status.

Reference equations for predicting standing height of children by using arm span or forearm length as an index.

BACKGROUND: Standing height (SH) is the most reliable parameter used to predict spirometric values in children, but measurement of this parameter may be difficult in children with thoracic or spinal abnormalities. This study was designed to establish reference equations to estimate SHs of children using their arm span length (ASL) or forearm ulnar length (UL) as an index. METHODS: Children aged 1-17 years were enrolled to measure their SH, body weight, ASL, and UL. Sex and age were also recorded. The relationship between SH and children's weight, age, ASL, and UL were analyzed. Regression equations using different indexes for SH of enrolled cases were used, and adults aged 18-64 years were also enrolled for comparison. RESULTS: A total of 512 children and 144 adults were enrolled. There was a strong linear relationship between SH and both ASL and UL in children and adults. Pearson's correlation coefficients of SH for ASL and UL were 0.989 and 0.968 (p < 0.001) in children and 0.933 and 0.845 (p < 0.001) in adults. The linear regression equations for estimating SH in children were calculated as SH = 9.363 + 0.943 ASL (r2 = 0.978, p < 0.001) and SH = 14.542 + 5.570 UL (r2 = 0.936, p < 0.001). In adults, age and sex were also added as indexes: SH = 59.849 + 0.642 ASL-0.047 Age +3.431 Sex (male = 1; female = 0) (r2 = 0.887, p < 0.001) and SH = 102.824 + 2.317 UL -0.049 age + 6.739 sex (r2 = 0.773, p < 0.001). CONCLUSION: Both ASL and UL have a significant linear relationship with SHs of children and adults. True SH can be estimated using regression equations with ASL or UL as a single index for situations where direct measurement of SH is difficult.

Comparative study on three different methods for arm-span measurement: the Japan environment and Children's study pilot.

BACKGROUND: Arm span is an important measure for the assessment of growth and hormone deficiency diseases. In an epidemiological survey, with a large number of subjects' indicators, it is especially valuable to establish methods which can measure both quickly and accurately. However, there are various methods, and the length of arm span may vary according to the medical institution. METHODS: The arm span of nine 6-year old subjects was measured using two institutional standard methods, A and B, and a third method C which is an improved method and has been used for the first time in this study. A, No-Wall, with heels together the child stretches the arms out to the sides. B, Wall & No-Line, the child stands against the wall with heels together and spreads the arms against the wall. C, Wall & Line, the method is the same as B except a paper with horizontal lines is placed on the wall. We measured twice by each method. RESULTS: The difference between the 1st and 2nd measurements was marginally significantly smaller by using method of C. CONCLUSION: The method C, which we improved, is the best way to measure arm span.

Los resultados indicaron que los individuos kosovares de ambos sexos son una población alta, sin embargo las mediciones no se acercaron a poblaciones en las naciones de mayor altura. Además, la extensión de brazo fue predecible en cuanto a la estatura en ambos sexos.

Association of Age at Menarche with Anthropometric Measures in Punjabi Bania Girls.

INTRODUCTION: Menarcheal age is the age at which menstruation begins. Menarcheal age is regarded as a sensitive indicator of physical, biological and psychological environment. AIM: 1) To determine the menarcheal age and to examine the relationship between current age at menarche with anthropometric measures in Punjabi bania girls. 2) To develop maturity standards for Bania girls. MATERIALS AND METHODS: The present cross-sectional survey was carried out on 200 bania girls at the age of onset of menarche. Menarcheal data was obtained by status quo method by asking about whether menarche has been experienced or not. In the present survey adolescent girls were interviewed with the help of pre-designed questionnaire. Statistical analysis was carried out in SPSS software, version 16.0. The data were analysed using descriptive statistics and one-way ANOVA. Pearson's correlation coefficient was used for correlation studies. RESULTS: A total of 200 Punjabi bania girls were examined in the study. The median age of onset of menarche in these girls was 12.3 years. Menarcheal age was positively associated with bi-acromial width, bi-iliac width and arm span. CONCLUSION: The present research has revealed secular trend in the age of onset of menarche as indicated by median age of 12.3 years in Bania girls. The bi-acromial width, bi-iliac width and arm span were also correlated with the age of menarche.
