Shorter Women Are More Dissatisfied with Their Height: An Exploration of Height Dissatisfaction in Australian Women

Height dissatisfaction has recently been found to be an important contributor to body dissatisfaction in males, however, there is currently limited research examining this relationship in women. The present cross-sectional study aimed to examine the link between height and height dissatisfaction in Australian women, and the extent to which height and height dissatisfaction relate to body dissatisfaction and quality of life. Additionally, it explored the height preferences of oneself and romantic partners in Australian women. A final sample of 172 Australian women was recruited to complete an online survey relating to height preference, height dissatisfaction, muscularity, drive for thinness, and quality of life. Results showed that there was a significant difference between the reported actual height of participants and their ideal height. We also found that shorter women tended to be more dissatisfied with their height and were more likely to believe that they were treated poorly due to their height. Our study also identified that the vast majority (84%) preferred a romantic partner taller than them. Results were comparable to men aspiring to be taller than they were. Future studies should consider height dissatisfaction as a potential contributing factor to poor quality of life and negative affect.

Adult Stature Estimation from Radiographic Metatarsal Length in a Contemporary Korean Population

The ability to estimate stature can be important in the identification of skeletal remains. This study aims to develop a Korean-specific equation predicting stature using radiographic measurements in the contemporary Korean population. 200 healthy Korean adults, including 102 males and 98 females, were randomly selected (age, range 20–86 years). The first and second metatarsals of the foot were measured by a standing X-ray using a digital medical image viewer. The result showed a statistically significant correlation between metatarsal length and stature in Korean populations (male, R = 0.46, p < 0.001; female, R = 0.454, p < 0.001). Values of correlation coefficients (R) of the equations were 0.431 to 0.477. Compared to equations derived from other races, the Korean-specific equation showed significantly lower error values for estimating the actual height of Koreans through cross-validation. In conclusion, this study is the first to propose a Korean-specific regression formula for estimating stature using metatarsal length and a verified formula for precise application to the Korean population. However, given the relatively low correlation coefficient, the stature estimation formula derived from this study can be utilized when other bones that allow more accurate stature estimation are not available.

Analysis of Method of Axillary Crutch Measurement

The purpose of this study was to determine which of the 3 methods axillary measurement best predict ideal crutch length. Ideal crutch length is defined as the length of the crutch, including accessories, obtained during stance when the crutch tip is 15.2cm lateral and 15.2cm anterior to fifth toe and the axillary pad is 6.4cm below the axillary fold. Two hundred and twenty-four (224) volunteers were measured for crutches using each of the following methods: 77% of actual height; actual height minus 40.6cm and anterior axillary fold to heel in supine position with arm adducted. The result of the calculation were statistically significant (p<0.01). However, 77% of actual height and actual height minus 40.6cm had the strongest relationship to the ideal crutch length r (person Product Moment Correlation Coefficient) = 0.941; r2 (linear regression correlation coefficient) = 0.89; p<0.01. Axillary fold heel method had r =0.917: r2= 0.84; P<0.01.

Height Prediction Using the Knee Height Measurement Among Indonesian Children

Background: Height is essential for assessing growth and nutrition in children. Assessing height with appropriate measurement is important, although in certain physically disabled and hospitalized children direct height measurement is almost not possible. In these situations, segmental measurements can be used as proxy height. Knee height (KH) has been determined as the most reliable surrogate. Objective: This study aimed to establish a height-predicted equation using KH for use in both community and clinical practices. Methods: This was a cross-sectional study design that collected data from 1114 healthy children (596 boys and 518 girls) aged 7 to 12 years to develop the equations for predicting height from KH. A multiple linear regression analysis was used to develop the equations. Results: Two equations were established to predict height using KH: (1) for boys H = 29.895 + (0.081 × age [months] + (2.267 × KH)) and (2) for girls H = 26.297 + (0.110 × age [months] + (2.278 × KH)). The very high correlation between KH and actual height indicates a very strong agreement. Conclusions: Knee height can be used for prediction equations for height with a very good predictive power. The age variable using the month unit generates a more accurate equation.

Evaluation of the Effects of Malnutrition Detected in Children and Adolescents on the Adult Final Height

Aim: It is known that chronic malnutrition observed in the early childhood creates many negative results in adult life. Studies examining the effects of nutritional deficiency experienced at older ages and in adolescence are quite limited. In other words, the long-term consequences of nutritional defect in acute/ chronic moderate or mild malnutrition patients still remains important as an issue to be investigated. For this purpose; In this study, it was aimed to determine the final adult height (predicted adult height) of children and adolescents with different age distribution and who were diagnosed with malnutrition as a result of nutritional-endocrinological anthropometric evaluations, and to compare these data with their genetic potential. Material and Methods: The study included 21 cases diagnosed with malnutrition in the pediatric endocrinology department. After the detailed history of the cases, anthropometric measurements and physical examination, biochemistry, hormonal and micronutritional status, celiac antibody levels were evaluated. In the anthropometric evaluation of all cases, body weight, height, height deviation, bone age, target height, target height deviation parameters were used. Patients’ pubertal development was determined according to Tanner-Marshall staging. In the determination of the nutritional status of the patients, data including Weight for Age (WA), Height for Age (HA) and Weight for Height (WH) were used as a nutritional anthropometric measurement using the Gomez-Waterlow classification. In addition, the predicted adult height was calculated with special formulas based on skeletal ages in all cases. Predicted adult height data were obtained using Bayley N Pinneau tables. Results: Of the 21 cases with an average age of 9.81±4.34 years, 12 were prepubertal and 9 were pubertal. Acute episode over chronic malnutrition was found in 19 cases, chronic in 2 cases and acute malnutrition in one case. Considering the severity of malnutrition; WA parameter was determined as severe malnutrition in 1 case, mild-moderate malnutrition in 20 cases, HA parameter was determined as normal in 12 cases, mild-moderate malnutrition in 9 cases, WH parameter was determined as normal in 3 cases, mild-moderate malnutrition in 18 cases. While the predicted adult height of all cases was 164.89±7.96 cm, the target height average of these cases was 166.5±8.09 cm. It was observed that the predicted adult height compared to the target height was the lowest in the chronic group. In seven cases with bone age below 6 years of age, the actual height deviations were distinctly behind the target height deviation. All of these cases were compatible with chronic malnutrition. Conclusion: These results are valuable in terms of showing that malnutrition experienced in any period of growth may negatively affect the predicted adult height. On the other hand, this research; It emphasizes the importance of nutritional anthropometry in all cases with or without short stature. In addition, in another study we conducted in 11 adolescents, it was found that nutritional defect negatively affected growth by decreasing IGF1/IGFBP3 levels, and growth factors increased and growth was supported in the cases that were nutritionally supported. In this study, if the nutritional deficiency is not replaced in patients with malnutrition, it suggests that even if the actual height is not affected, there will be retardation in the final height of the patients.

Validated predictive equations based on tibial length in estimating height for children with cerebral palsy for 2–18 years, across all GMFCS levels

Children with cerebral palsy (CP) typically suffer from congenital deformities, such as scoliosis and contractures, therefore, it is a challenge to measure the stature of CP children. Studies have suggested that predictive equations based on tibia length (TL) may be used as an alternative method in measuring the actual height or stature. The present study aimed to develop and validate predictive equations based on TL for CP children in Malaysia across all five levels of gross motor functions (GMFCS I to V) through a cross-sectional study. All subjects were recruited from Hospitals and Community-Based Rehabilitation (CBR) in the central and southern regions of Malaysia. Two predictive equation models were developed using multiple linear regression. For Model 1, the predictive equation was developed based on TL. On the other hand, Model 2 was developed based on TL with age was included. A flexible Seca measuring tape was used to measure the stature and TL. CP children aged 2–18 years were classified into the equation development group (EDG), n 177 and the validation group (VG), n 139. Model 1, Height = 32⋅3 + 3⋅14 (TL), demonstrated a strong correlation with the actual height (R2 0⋅834), small SEE (1⋅42), and high intra correlation coefficient (0⋅929). The findings suggested that Model 1 was more accurate in estimating the height of CP children aged 2–18 years. This model was shown to suit the Malaysian population and applicable across all GMFCS levels.

Prediction of clinical height gain from surgical posterior correction of idiopathic scoliosis

OBJECTIVEThe best predictors of height gain due to surgical correction are the number of fused vertebrae and the degrees of the corrected Cobb angle. Existing studies of predictive models measured the radiographic spinal height and did not report the clinical height gain. The aims of this study were to determine the best predictive factors of clinical height gain before surgical correction, construct a predictive model using patient population data for machine learning, and test the performance of this model on a validation population.METHODSThe authors reviewed 145 medical records of consecutive patients who underwent surgery that included placement of posterior spinal instrumentation and fusion for idiopathic scoliosis between 2012 and 2016. Standing and sitting clinical heights were measured before and after surgery in patients who had been surgically treated under similar conditions. Multivariate analysis was then performed and the results were used to develop a predictive model for height gain after surgery. The data from the included patients were randomly assigned to a learning set or a test set.RESULTSIn total, 116 patients were included in the analysis, for whom the average postoperative clinical height gain in a standing position was 4.2 ± 1.8 cm (range 0–11 cm). The best prediction model was calculated as follows: standing clinical height gain (cm) = 1 − 0.023 × sitting clinical height (cm) − 0.19 × Risser stage + 0.058 × Cobb preoperative angle (°) + 0.021 × T5–12 kyphosis (°) + 0.14 × number of levels fused. In the validation cohort, 91% of the predicted values had an error of less than one-half of the actual height gain.CONCLUSIONSThis predictive model formula for calculating the potential postoperative height gain after surgical treatment can be used preoperatively to inform idiopathic scoliosis patients of what outcomes they may expect from posterior spinal instrumentation and fusion (taking into account the model’s uncertainty).

Potential of Pléiades and WorldView-3 Tri-Stereo DSMs to Represent Heights of Small Isolated Objects

High-resolution stereo and multi-view imagery are used for digital surface model (DSM) derivation over large areas for numerous applications in topography, cartography, geomorphology, and 3D surface modelling. Dense image matching is a key component in 3D reconstruction and mapping, although the 3D reconstruction process encounters difficulties for water surfaces, areas with no texture or with a repetitive pattern appearance in the images, and for very small objects. This study investigates the capabilities and limitations of space-borne very high resolution imagery, specifically Pléiades (0.70 m) and WorldView-3 (0.31 m) imagery, with respect to the automatic point cloud reconstruction of small isolated objects. For this purpose, single buildings, vehicles, and trees were analyzed. The main focus is to quantify their detectability in the photogrammetrically-derived DSMs by estimating their heights as a function of object type and size. The estimated height was investigated with respect to the following parameters: building length and width, vehicle length and width, and tree crown diameter. Manually measured object heights from the oriented images were used as a reference. We demonstrate that the DSM-based estimated height of a single object strongly depends on its size, and we quantify this effect. Starting from very small objects, which are not elevated against their surroundings, and ending with large objects, we obtained a gradual increase of the relative heights. For small vehicles, buildings, and trees (lengths <7 pixels, crown diameters <4 pixels), the Pléiades-derived DSM showed less than 20% or none of the actual object’s height. For large vehicles, buildings, and trees (lengths >14 pixels, crown diameters >7 pixels), the estimated heights were higher than 60% of the real values. In the case of the WorldView-3 derived DSM, the estimated height of small vehicles, buildings, and trees (lengths <16 pixels, crown diameters <8 pixels) was less than 50% of their actual height, whereas larger objects (lengths >33 pixels, crown diameters >16 pixels) were reconstructed at more than 90% in height.

FEATURES OF LAND RECLAMATION AND PROTECTION DURING MINING IN THE KRASNOYARSK TERRITORY

The purpose of the study is to influence land resources during mining operations, and the main stages of land reclamation during mining on the example of the Tyradinsky gold Deposit, the "Zolotaya Tyrada" quarry, located in the Yenisei region of the Krasnoyarsk territory. The main factors of impact on land resources in the process of mining the field are considered; the analysis of measures to reduce the negative impact on land resources in the process of mining the field is carried out. The actual height and area of overburden dump not to exceed project, the reconfiguration of dumps allowed us to reduce the impact of mining on the environment, to avoid placing parts of the dumps in the water protection zone of the river Terada, thus there is no need of land allocation to forests of the first group and reduced the amount of removed topsoil. During the reclamation, potentially fertile soils (loam) taken from the quarry were used. There will be no deterioration in the impact on land resources during the liquidation process, due to the short duration of the work and within the existing land allotment.
