The Relationship

The study was done to establish the relationship between measured renal volume and body parameters to estimate standard reference value of renal volume related body parameters (RV-BMI, RV-BSI and RV-BSA) in Ghana for clinical application. The estimates were done based on age and gender variation and compare the established standard reference renal volume with its related body parameters. The weight and BMI measuring machine together with tape measure and glass beaker were the measuring tools used. The procedure involve measurement of body height and weight and using the estimated values to calculate BMI with the BMI calculator. It also involve using DuBois formula to estimate local standard reference values of BSI and BSA in Ghana. The reference standard renal volume was determined using water displacement with the Archimedes' principle to confirm the established values in Ghana. These value were compare with established standard reference renal volume model in Ghana which were estimated using abdominal images on MeVisLab application software platform and determined the relationship between these parameters. The determined Ghanaian standard reference renal volume were: 146.74cm3, 151.76cm3, 142.04cm3 and 148.29cm3 for male and female, with its corresponding right and left kidneys respectively. The estimated mean BMI, BSI and BSA were; 25.19kg/m2 39.81 kg/m2 and 2.02m2 for male and 21.91kg/m2 36.58kg/m2 and 1.69m2 for female respectively. Hence from these set of values, the relationship between renal volume and its related BMI was determined to be 6.04cm3-kg/m2 for male and 6.47cm3-kg/m2 for female. While the male RV related-BSA was also determine to be 74.05cm3-m2 and 84.09cm3-m2 for female. Finally, the renal volume related-BSI was also estimated to be 3.81cm3-kg/m2 for male and 3.88cm3-kg/m2 for female. The standard reference renal volume related BMI, BSI and BSA are recommended to be used for renal assessment for clinical application in Ghana.

Individual Body

The relationship between body height and body weight has been described by using various terms. Notable among them is the body mass index, body surface area, body shape index and body surface index. In clinical setting the first descriptive parameter is the BMI scale, which provides information about whether an individual body weight is proportionate to the body height. Since the development of BMI, two other body parameters have been developed in an attempt to determine the relationship between body height and weight. These are the body surface area (BSA) and body surface index (BSI). Generally, these body parameters are described as clinical health indicators that described how healthy an individual body response to the other internal organs. The aim of the study is to discuss the use of BSI as a better clinical health indicator for preclinical assessment of body-organ/tissue relationship. Hence organ health condition as against other body composition. In addition the study is `also to determine the best body parameter the best predict other parameters for clinical application. The model parameters are presented as; modeled height and weight; modelled BSI and BSA, BSI and BMI and modeled BSA and BMI. The models are presented as clinical application software for comfortable working process and designed as GUI and CAD for use in clinical application.

The study is based on measurements of renal dimensions to determine standard reference renal volume model and renal volumetric ellipsoid coefficient. Two methods, Voxel count method and rotational renal ellipsoid equation were the two measuring tools used with an integrated MVL application software platform. The procedure involve measurement of linear dimensions together with using the snake technique to draw the region of interest (ROI) for the volumetric measurements. These were done to obtain: renal length, lateral diameter, A-P diameter and the total number of voxels to estimates the renal volume. These parameters were used to calculate renal volume using the rotational renal ellipsoid equation as well as using the Minitab statistical software to model renal volume equation. The reference standard renal volume was also determined using water displacement with the Archimedes' principle. The average renal shape index and its dispersion (i.e. covariance matrix) was approximately 1±0.02. The male average measured values for right and left kidneys were as follows: renal length, 103.35cm and 105.13cm, lateral diameter, 60.79 and 60.40 and A-P diameter, 44.12 and 44.95 and renal volume; 146.74cm3 and 151.76cm3 respectively. Furthermore, the female average measured values for right and left kidneys were as follows: renal length, 101.43 and 102.98, lateral diameter, 59.20 and 59.02 and A-P diameter, 43.09 and 44.82, renal volume 142.04cm3 and 148.29cm3 respectively. The average estimated renal volumetric ellipsoid coefficient (VeC) was 0.53. However, various variations for both male and female, with their corresponding right and left kidneys were, 0.5283, 0.5297, 0.5280 and 0.5304 respectively. The reference renal dimensions including the standard renal volume and renal volumetric ellipsoid coefficient are recommended for clinical application in Ghana.

Background: Knowledge of normal renal volume is a vital parameter for clinical assessment of renal diseases because renal size is altered by various medical conditions. Variations in renal dimension in different populations and it’s relation to individual’s body parameters are evident. Different studies have recommended the need for measurement of renal dimension for specific population. This study assesses normal range of renal volume in the study population and measures their correlation with individual’s body parameters.Methods: This descriptive study was done in 261 adults. After renal length measurement on reformatted coronal images, renal width and renal thickness on axil images, renal volume was calculated by ellipsoidal formula. Descriptive statistics and parametric tests were used to evaluate the association between renal volume and different parameters.Results: This study showed a significant difference in mean renal volume between male (right and left mean renal volume 120.52 ± 26.84 cm3 and 121.00 ± 27.23 cm3 respectively) and female (right and left mean renal volume 110.11 ± 21.79 cm3 and 111.15 ± 22.34 cm3 respectively) on each side. Similarly, a significant positive correlation was found between renal volume and body height, body weight and BMI of participant for both kidneys however a significant negative correlation was observed between renal volume and age 40 years and above for both kidneys.  Conclusions: This study provides morphometric data regarding normal kidneys and concludes that male renal volume is more than female and renal volume is correlated to individual’s body parameters.Keywords: Morphometric; nomogram; renal volume

The Relationship

The heart is a muscular organ about the size of a closed fist that function by pumping blood throughout the body making the body size extremely important in its performance. Hence, the work done by the heart depend largely on the total body size of the individual, measurements of which depends on the weight and height to estimate BMI, BSA and BSI. The aim of the study was to establish Ghanaian based standard reference values of cardiothoracic ratio and determine the relationship with body parameters for clinical application. The maximum transverse diameter of the heart was obtained by adding the widest distance of the right heart border from the midline and the left heart border to the midline (cardiac diameter). This value was then divided by the maximum transverse diameter of the thorax (the thoracic diameter) to give the cardiothoracic ratio (CTR). Which is described as a ratio of the cardiac width as against thoracic width. The measured CTR was approximately 15: 33 (cm) and is therefore within the normal limit of 50%. This is because a CTR of greater than fifty percent is abnormal, in terms of Posterior - Anterior (PA) or an Anterior - Posterior (AP) view. In addition, the height and weight were measured to estimate the BMI, BSA and BSI and the relationship of these parameters with the measured cardiothoracic ratio. The result shows that BSI better correlate with the cardiothoracic ratio than any other body parameter with 92.53% accuracy rate. The determination of the CTR which represent the size of the normal heart is of the greatest importance to cardiologists. This is because the heart size enlargement is better assess by determining the ratio of size of the heart (cardiac diameter) as against the size of the chest wall (the thoracic diameter). This is use for initial assessment of heart condition by cardiologist, with a standard adult heart having a CTR value of 0.5. The study shows that a normal size is so variable and depends so greatly on the sex, age and body parameters of the study population. In conclusion, the study will serve as basis of the relationship between body parameter and the CTR. It also established that a deviation of heart size with BSI may reveal an underlying pathologic condition, and called for further studies to be conducted for clinical decision.

Abstract. The ratio of second to fourth finger length (2D:4D ratio) is sexually dimorphic with women having higher 2D:4D ratio than men. Recent studies on the relationship between 2D:4D ratio and gender-role orientation yielded rather inconsistent results. The present study examines the moderating influence of nationality on the relationship between 2D:4D ratio and gender-role orientation, as assessed with the Bem Sex-Role Inventory, as a possible explanation for these inconsistencies. Participants were 176 female and 171 male university students from Germany, Italy, Spain, and Sweden ranging in age from 19 to 32 years. Left-hand 2D:4D ratio was significantly lower in men than in women across all nationalities. Right-hand 2D:4D ratio differed only between Swedish males and females indicating that nationality might effectively moderate the sexual dimorphism of 2D:4D ratio. In none of the examined nationalities was a reliable relationship between 2D:4D ratio and gender-role orientation obtained. Thus, the assumption of nationality-related between-population differences does not seem to account for the inconsistent results on the relationship between 2D:4D ratio and gender-role orientation.

Research background and hypothesis. The analysis of factors which might infl uence exercise adherence is important issue for physical activity promotion. Studies show that exercisers’ body image is important factor associated with well being, exercise motivation and specifi c exercise–related behaviour.Research aim was is to examine the relationship between exercise adherence, body image and social physique anxiety in a sample of fi tness centre participants. Research methods. Members of fi tness centres (n = 217, 66 of them were women) provided their answers on exercise experience, in three subscales (appearance evaluation, appearance orientation and overweight preoccupation) of The Multidimensional Body-Self Relations Questionnaire (MBSRQ-AS; Brown et al., 1990) and Social Physique Anxiety Scale (SPAS; Hart et al., 1989). Mean age of the sample was 29.02 (9.85) years (range = 18–68 years).Research results. Women demonstrated higher appearance orientation, overweight preoccupation and social physique anxiety compared to men. However, we observed no signifi cant differences in appearance evaluation, appearance orientation and overweight preoccupation in the groups of different exercise experience of men and women. When overweight respondents (≥ 25 kg / m²) were excluded from the analysis, there were no statistically signifi cant differences observed in body image and social physique anxiety in exercise experience groups of men and women. Exercising longer than 6 years signifi cantly predicted overweight preoccupation [95% CI: 1.25–16.94] controlled by age and gender. Discussion and conclusions. Exercising men demonstrated more positive body image and lower social physique anxiety compared to women, except for appearance evaluation. There were observed no body image and social physique relationships with exercise adherence observed in the sample of fi tness centre participants, however, exercise experience longer than 6 years predicted overweight preoccupation.Keywords: body image concerns, exercise experience, self-presentation.

The Relationship

Research on the relationship between fertility and gender ideology revealed inconsistent results. In the present study, we argue that inconsistencies may be due to the fact that such relationship may be nonlinear. We hypothesize a U- shaped relationship between two dimensions of gender ideology (i.e. primacy of breadwinner role and acceptance of male privilege) and fertility rates. We conducted a cross-national analysis of 60 countries using data from the World Values Survey as well as the World Population Prospects 2019. Controlling for gross domestic product, we found support for a U-shaped relationship between gender ideology and fertility. Higher levels of fertility rates were found at lower and especially higher levels of traditional gender ideology, while a medium level of gender ideology was associated with the lowest fertility rate. This curvilinear relationship is in agreement with the phase of the gender revolution in which the country is located. Traditional beliefs are linked to a complementary division of private versus public sphere between sexes, while egalitarian attitudes are associated with a more equitable division. Both conditions strengthen fertility. Instead, as in the transition phase, intermediate levels of gender ideology’s support are associated with an overload and a difficult reconciliation of the roles that women have to embody (i.e. working and nurturing) so reducing fertility. The present study has contributed to the literature by addressing the inconsistencies of prior research by demonstrating that the relationship between gender ideology and fertility rates is curvilinear rather than linear.
