The Relationship

The relationship between predator and prey size was studied in the buprestid hunting wasp Cerceris fumipennis Say in eight widely distributed nesting aggregations in North Carolina, USA. Initial work indicated a significant linear relationship between wasp head width and wasp wet weight; thus, head width was used to estimate wasp body mass in subsequent studies. Prey loads of hunting females was studied by measuring the head width of the wasp, then identifying and weighing the prey item brought back to the nest. There was significant variation in wasp size among nesting aggregations; the average estimated wasp body mass in one site was double that in another. Prey weight varied with wasp weight, but larger wasps had a slight tendency to carry proportionally larger prey. Beetles captured by large wasps (≥120 mg) were significantly more variable in weight than those taken by small wasps (<80 mg). All but the smallest wasps could carry more than their own body weight. Prey loads ranged from 4.8–150.2% of wasp weight. Evidence suggests that small wasps bring back more of the economically important buprestid genus Agrilus and thus would be most efficient in biosurveillance for pest buprestids.

The Relationship

1. A method is described by means of which the surface area of puparia of Drosophila melanogaster may be measured. 2. Measurement of almost 200 puparia showed that the relationship between surface area, per mg., and body weight could best be expressed in the form of the equation S=7.7049-2.1099X, where S=surface area, sq. mm. per mg. wet weight, for prepupae of mean wet weight X mg. As the standard error of estimate, ±0.117, is equal to only 2.2% of the mean surface area per mg., the surface area can be accurately estimated from the wet weight. 3. The prepupal oxygen consumption, per mg. wet weight, is shown to decrease steadily with increasing body weight; with an increase in mean wet weight from 0.847 to 1.700 mg., the oxygen consumption, per mg., decreases by about 50%. 4. Utilizing the above regression equation, the surface area of prepupae of known oxygen consumption was estimated and thus the oxygen consumption per sq. mm. of body surface. These values show no significant variation with increasing body weight, so that it can be concluded that the oxygen consumption of prepupae of D. melanogaster is proportional to the surface area.

Whether paternal epigenetic information of nutrition might be inherited by their offspring remained unknown. evaluate the relationship between preconception paternal body weight and their offspring's birth weight in 1,810 Chinese mother-father-baby trios. Information on paternal and maternal preconception body weight and height was collected via a self-reported questionnaire. Birth weight was collected from medical records. Paternal preconception body weight was associated with offspring's birth weight (p trend=0.02) after multivariable adjustment. Each standard deviation increment of paternal body mass index was associated with an additional 29.6 g increase of birth weight (95% confident interval: 5.7g, 53.5g). The association was more pronounced in male neonates, and neonates with overweight mothers, and with mothers who gained excessive gestational weight, compared to their counterparts (all p interaction<0.05). Sensitivity analyses showed similar pattern to that of the main analysis. Paternal preconception body weight was associated with birth weight of their offspring.

Background and Objectives. The purpose of the study was to investigate the relationship between children’s birth weight/length and a risk of overweight and obesity. Materials and Methods. The study involved 747 children from kindergartens, as well as primary and middle schools from southeastern Poland. All the subjects were examined on fasting status. Each child was examined for body mass and height, in order to calculate their body mass index (BMI), and BMI centile. The parents completed a questionnaire related to basic information about the child and the family. Results. In the study group, the male infants presented greater birth body weight and birth body length. A comparison of the distribution of birth weights and lengths between the children with normal BMI and with high BMI showed statistically significant differences only in the case of birth length of 12–15-year-old children and in the group of boys aged 12–15 years. In the case of the female children and the group of 7–11-year-olds a statistically significant difference was found in the BMI centile at a later age—a higher centile was found in the girls and in the children aged 7–11 years classified as adequate for gestational age (AGA). Conclusions. Birth body weight is positively related to BMI centile; however, no significant differences were found in birth weight between children with overweight/obesity and children with normal body weight. Birth length is associated with a lower BMI centile only in boys aged 12–15 years, and lower birth length is found in boys with overweight and obesity.

This study assesses the relationship between negative interaction and body mass index values among older adults. Throughout, an emphasis is placed on probing for individual differences in response to unpleasant encounters with significant others. Individual variations in personality (introversion-extraversion) as well as social status (gender) are evaluated within this context. Tests of the complex three-way interaction between negative interaction, gender, and introversion reveal that more negative interaction is associated with higher body mass index values among elderly women who are introverted. In contrast, a significant relationship between negative interaction, introversion, and body mass failed to emerge for older men.

Respiratory Area

Relationships between respiratory area, oxygen consumption, and body mass have been examined during the development of water- and air-breathing fish. It is concluded that there is at least one stage at which the slope of the relationship between log gill area and log body weight changes during fish development. This usually occurs in the weight range 0.05–1.0 g and is often associated with a distinct metamorphosis, but no common functional significance can be attached to them. However, the change in slope does not appear to be associated with a comparable inflexion in the corresponding relationship between body mass and oxygen consumption (routine). It seems probable that other surfaces are important during these transitions and that the total gas-exchange surface of the fish shows a more constant change throughout the life history. Further analyses of a wider range of species is required to test this hypothesis.

Body mass index (BMI) is to monitor nutritional status adults, especially those related to deficiency and overweight. Body fat percentage can describe the risk of degenerative diseases.This study was conducted to measure the relationship between BMI and body fat percentage. Methods An analytical study was conducted to 41 male and 51 female participant from Universitas Teuku Umar. The body weight was measured using scales, whereas the body height was measured using microtoise. The body fat percentage was measured using Karada Scan. The BMI was calculated by dividing the body weight in kilogram divided by body height in meter square. Data was collected from 16-18th February 2021 and analyzed by Pearson’s correlation test. The results showed BMI underweight, normal, and overweight were 10,9, 57,6, and 31,5. High body fat percentage in men were 75,6% and in women were 35,5%. There is a relationship between the nutritional status of the women group and the body fat percentage with p-value is obtained = 0.021. Furthermore, for men, there is no relationship between nutritional status in the men group and the body fat percentage. There is a relationship between nutritional status and body fat percentage in women. Among this population, BMI can still be used to determine body fat percentage

Introduction: Alterations in foot landing position have often been associated with the appearance of deformities in lower limbs. However, there are no studies that prove the relationship between these two variables in healthy individuals. Objective: To investigate the relation between changes in feet and lower limbs by plantigraphy and computerized photogrammetry. Methods: The study included 70 young adults, 42 women (height: 1.60±0.01 m; body weight: 58.0±0.92 kg; body mass index: 22.0±0.31 kg/m2 ) and 28 men (height: 1.70±0.01 m; body weight: 70.0±1.4 kg; body mass index: 23.0±0.42 kg/m2 ) with mean age of 21.62±2.0 and 22.18±2.09 years, respectively. Plantigraphy of both feet and photographic capture in the anterior frontal plane of lower limbs and foot, posterior frontal of the tendon of the calcaneus and in the sagittal plane of lower limbs were performed. Results: A strong positive correlation was observed between the Chippaux-Smirak and the Staheli indexes (Men– r: 0.863 and p<0.001; Women– r: 0.973 and p<0.001) and a weak positive correlation between the malleolar angle and the Cavanagh-Rodgers index (Men– r: 0.386 and p 0.003; Women– r: 0.280 and p 0.010). Conclusion: There was no correlation between footprint indexes and lower limb angles measured by computerized photogrammetry.

187 Background: Cancer anorexia-cachexia syndrome (CACS) in patients is associated with decreases in lean body mass and body weight. Self-reported lack of appetite may be an important indicator for early identification of CACS. The current analyses examined the relationship of perceived lack of appetite to patient characteristics and overall symptom burden in a large mixed cancer sample referred to a palliative care clinic. Methods: We conducted a retrospective review of patients newly referred to an outpatient palliative care clinic over a two-year period. Data on demographic and clinical characteristics and patient-reported symptom scores on the Edmonton Symptom Assessment Scale (ESAS) were abstracted. Pearson’s correlations and ANOVAs were used to assess relationships between variables. Multiple regression analysis was used to evaluate the relative contribution of variables that were significantly correlated with lack of appetite at the univariate level. Results: Data on 544 patients ( M=53.7 years) showed that older age (r=12, p<.01), not being married or in a marriage-like relationship (r=.09, p=.04), having insurance other than managed care insurance (r=.10, p=.02), lower body mass index (BMI; r=.11, p<.01), marijuana use (r=.18, p<.0001), and overall symptom burden (ESAS total score r=.52, p < .0001) were associated with worse lack of appetite ( M=3.5, SD=3.1). Patients who were underweight (BMI <18.5, 46.7%) reported significantly worse lack of appetite than patients who were normal weight, overweight, or obese ( M=3.9, SD=3.2, p<.01). The final hierarchical regression model accounted for 34% of the variance in lack of appetite, with age, marital status, BMI, marijuana use, and total symptom burden remaining significant independent correlates (p’ s <.01). Conclusions: Contrary to expectations, relatively few clinical correlates were associated with self-reported lack of appetite. Future research should explore inter-individual genetic factors to explain alterations in lean body mass and body weight that may contribute to poor appetite in patients. Such factors may be important indicators for early identification of CACS.

The current investigation aimed to comparatively examine the effects of minimalist, maximalist and conventional footwear on Achilles tendon forces (ATF) during running. Twelve male runners (age 23.11±5.01 years, height 1.78±0.10 cm and body mass 77.13±7.89 kg) ran at 4.0 m/s in the three footwear conditions. ATF’s were calculated using Opensim software allowing the magnitudal and temporal aspects of the ATF to be quantified. Differences between footwear were examined using one-way repeated measures ANOVA. The results showed the peak ATF was significantly larger in minimalist footwear (5.97±1.38 body weight (BW)) compared to maximalist (5.07±1.42 BW). In addition it was revealed that ATF per mile was significantly larger in minimalist (492.31±157.72 BW) in comparison to both maximalist (377.31±148.06 BW) and conventional (402.71±125.51 BW) footwear. Given the relationship between high ATF and Achilles tendon degradation, the current investigation indicated that minimalist footwear may increase runners risk for Achilles tendon injury.
