Somatotype and angiographically determined atherosclerotic coronary artery disease in men

Evaluation of the effects of somatotype profiles on pain, proprioception, isokinetic muscle strength and kinesiophobia in patients with meniscopathy

BACKGROUND

Somatotype causes differentiation of physical, physiological and biochemical metabolisms in the body. To what extent meniscopathy (M) is affected by somatotype profiles has been an issue of concern.

OBJECTIVE

The aim of the study was to investigate whether somatotype profiles have an effect on kinesiophobia, pain, proprioception and isokinetic muscle strength in patients with an M diagnosis.

METHODS

172 (85 female, 87 male) M patients between the ages of 18 and 65 were included in the study. The Heath-Carter method was used to determine somatotype components. Biodex Isokinetic system at 120∘/sec angular speed was used for muscle strength measurements, a digital inclinometer with goniometer was used for proprioception measurement, the Tampa Kinesiophobia Scale (TKS) was used for the assessment of kinesiophobia, the Functional Assessment of Chronic Illness Therapy (FACIT) fatigue scale was used for the assessment of fatigue and pain, and the visual analogue scale (VAS) was used for pain assessment.

RESULTS

Five somatotype profiles were found. When the right-left knee proprioception values were compared according to the somatotype profiles of patients, a significant difference was found in favor of balanced ectomorph at 15∘ and 30∘. No significant difference was found when TKS, FACIT, VAS values were compared in terms of somatotype profiles; while no significant difference was found in TKS, FACIT, VAS (REST-NIGHT) in terms of gender, a significant difference was found in VAS MOVE. Endomorph somatotype was dominant in the M patients.

CONCLUSIONS

Individuals with M disease showed significant differences in terms of endomorph components. Obesity may also be one of the negative findings for M disease. Somatotype classification may represent a suitable tool for monitoring M.

The association between somatotype and nutritional status: a cross-sectional study among the adult Sabar males of Purulia, West Bengal, India

Somatotype is the parameter used to determine the body composition, which is influenced by several factors and nutrition is the crucial one. This study aimed to determine somatotype and nutritional status as well as investigate the somatotype variations in relation to the age and nutritional status among the adult males of Sabar community living in Purulia district of West Bengal, India. The present cross-sectional study included 334 Sabar males aged between 18 to 60 years. Anthropometric measurements including height, weight, 2 breadths, 2 circumferences and 4 skinfolds were taken following standard protocol. Somatotype was determined following the Heath-Carter method and Body Mass Index (BMI) was used to access the level of nutrition. Descriptive statistics, Kruskal-Wallis H test, Pearson correlation, Spearman correlation and Chi-square test were performed to find out variation, correlation and association of the somatype components with age and nutritional categories. Prior ethical clearance had been obtained. As a result, the trend of undernutrition was gradually increasing with age and found highest among aged people (50–60 years) with an overall prevalence of 49.7%. Eleven different somatotype subgroups were identified. The mean somatotype of the participants was 2.3–3.6-3.9 which indicates mesomorph-ectomorph body type. Kruskal-Wallis H test revealed significant differences among somatotype components in different nutritional categories. Undernutrition was found highest among the mesomorphic ectomorph (62.7%) type. Chi-square test stated significant association between somatotype categories and nutritional statuses (Chi-square = 283.160, p < 0.01). This is the first reporting on the somatotype study among the Sabar community, where the dominant body type was found mesomorph-ectomorph. A highly significant correlation was found between somatotype and BMI. At the same time, this study expressed the need for immediate nutritional intervention.

Assessment of heart rate variability for different somatotype category among adolescents

Background Somatotype is a quantified expression of the morphological conformation of a person in terms of three-numeral rating each representing one component; fat (endomorphy), muscle mass (mesomorphy) and bone length (ectomorphy) in the same order. Certain somatotypes are more prone to develop the particular disease. Obesity and overweight are already epidemic among Indian adolescents and are increasing at an alarming rate, and obesity is linked to cardiovascular (CV) risk in this age group. Identifying the heart rate variability (HRV) is an established non-invasive test to identify the CV risk. The objective of this study is to record the HRV data for each somatotype category and to compare the HRV data among these somatotype categories in adolescents. Methods The volunteer adolescents in the age group of 12-17 years were classified into a different somatotyping categories based on the Heath Carter somatotyping method. The short-term HRV was recorded in all the subjects using wireless BioHarness 3.0. Results Based on the time domain and frequency domain parameters, the parasympathetic activity showed decreasing order as follows: central>ectomorphy>mesomorphy>endomorphy, whereas sympathetic activity showed increasing order as follows: central<ectomorphy<mesomorphy<endomorphy in both boys and girls. Girls have higher parasympathetic activity and lesser sympathetic activity than boys in ectomorphy and mesomorphy. In the central somatotype and endomorphy categories, genders were comparable. Conclusion Our study suggests that endomorphy and mesomorphy have poorer autonomic tone when compared to other somatotype categories.

Somatotype, diet and nutritional status of women

The relationship between energy value and nutrients intake and the body shape and size parameters (weight, height, waist and hip circumferences) has become an interesting research area for nutritionists and dieticians. The aim of this study was to determine the relationship between the body shape and size parameters (weight, height, waist and hip circumferences), somatotype (according to the Rohrer (RI) index) and energy value and nutrients intake of women. The study was conducted in 2014 and 2016 on 148 female volunteers aged 57-88 from the Mazovian and Lublin province (Poland). Sample selection was targeted at elderly people with different body types. The exclusion criteria were: multi-organ failure, cancer and disability. Then among the subjects, a survey was conducted, that included demographic data, lifestyle, health status and vitamins and minerals supplements use. Food intake has been assessed using a 3-day dietary food records. The somatotype was determined using the RI with the Curtis key, classifying the subjects as ectomorphic (n=30), mesomorphic (n=31) and endomorphic (n=87). The somatotype was significantly related to place of residence, physical activity, waist and hip circumference, WHR and BMI index, total protein intake, animal protein intake, vitamin E intake (p≤0.05) and to fat, phosphorus and thiamine intake (p≤0.1). The obtained results showed that the place of residence, physical activity, chronic diseases, the use of specialized diet, body weight fluctuations, BMI and WHR were different depending on the somatotype in the examined group of women. Endomorphic subjects had significantly greater waist and hip circumference and diastolic blood pressure compared to the other somatotypes. The somatotype had only a significant effect on total protein, animal protein and vitamin E intake, and ectomorphic elderly women may be particularly susceptible to nutrient deficiencies. Due to the risk of macronutrient, vitamin and mineral deficiencies in the diets of the examined women, it seems necessary to educate this group as well as caregivers and doctors in the area of nutrition adapted to the needs of the elderly.

The relation of somatotypes and stress response to central serous chorioretinopathy

PURPOSE

To investigate a possible relationship between central serous chorioretinopathy (CSC) and specific body types and compositions (somatotypes), and to examine the cortisol stress response among CSC patients of different somatotypes in comparison with healthy subjects.

METHODS

Prospective case-control study. A group of 28 patients with a previous or current diagnosis of CSC was compared with a group of 26 healthy subjects. Anthropometric measurements were used to estimate somatotype ratings in all subjects. Serum cortisol was measured at rest and following a stress-inducing computerized test in order to estimate response to stress in both groups. The main outcome measures included somatotype categorization and the change in serum cortisol following stress in both groups.

RESULTS

No significant difference in somatotype composition was found between the groups. There was no statistically significant difference between the groups in the elevation of cortisol following the stress-inducing test. The sample size was too small to exclude or find any significant difference between the different 13 subgroups of somatotype composition in the elevation of cortisol.

CONCLUSIONS

Our study did not show a typical somatotype related to CSC. While previous studies showed higher cortisol values in CSC patients, we did not see a higher elevation in blood cortisol following a stress response in this group in comparison with healthy subjects.

Body composition and personality traits in so-Yang type males

BACKGROUND

The purpose of the present study was to examine the body composition of So-Yang type males according to Sasang constitutional medicine, which is popular in Korea. Different Sasang constitutional types are associated with different muscle distributions, body shapes, and disease susceptibilities. We used the Sasang Personality Questionnaire (SPQ) as a measure of the temperament of each Sasang type.

METHODS

In total, 953 subjects aged over 20 years were recruited in Korea. We collected anthropometric parameters and bioimpedence information from the subjects and administered the SPQ. A logistic regression was conducted to calculate propensity scores.

RESULTS

The percentage of skeletal muscle mass in So-Yang (SY) and non-So-Yang (non-SY) males was 45.8 ± 2.7 and 44.2 ± 3.3, respectively, before matching and 45.8 ± 2.6 and 44.9 ± 3.0, respectively, after propensity score matching. The extracellular water (ECW)/intracellular water (ICW) and extracellular water (ECW)/total body water (TBW) ratios and SPQ scores were significantly different between the SY and non-SY types.

CONCLUSIONS

This study suggested that the SY type may be significantly and independently associated with body composition and could be associated with personality.

Selecting the implant height in breast augmentation with anatomical prosthesis: the "number Y"

BACKGROUND

Selecting the appropriate implant is one of the most important and demanding decisions in breast augmentation with anatomical implants, because different widths, heights, and projections can be found for a given volume. Most of the related literature and surgeons' concern have focused on width and projection. Implant height selection, however, has remained deeply overlooked, and it has been assumed that it depended on the suprasternal notch-to-nipple distance and, to a large extent, on the patient's height.

METHODS

With more than 5123 breast augmentations performed over the past 15 years, the authors performed an analysis of the breast and implant height with consequences in aesthetic augmentation of the breast. Two concepts--breast implantation base (or breast footprint) and somatotype--were explored. Their influence in the selection of the appropriate anatomical implant height is investigated.

RESULTS

Selection of implant height should follow the patient's breast implantation base, which is highly influenced by her somatotype. With this assumption, a "number Y" is proposed that correlates the suprasternal notch-to-nipple distance with the thoracic perimeter and unveils the shape of the breast implantation base in the particular patient.

CONCLUSIONS

Adjusting the implant shape/footprint to the breast implantation base/breast footprint gives the surgeon control over the upper pole of the breast and allows a predictable postoperative result. The number Y rationalizes the selection of the implant height in breast augmentation.

Validity of an alternative anthropometric trait as cardiovascular diseases risk factor: example from individuals with traumatic lower extremity amputation

BACKGROUND

Published studies reveal that individuals with lower extremity amputation are vulnerable to cardiovascular diseases (CVD) because of poor physical activity level. Many cardiovascular risk assessment studies have utilized anthropometric traits (primarily body mass index and waist circumference) as cardiovascular risk factor. However, some studies emphasized the technical limitations of measuring waist circumference for studying cardiovascular risk, and so it is difficult to obtain correct measurement from the individuals with lower extremity amputation.

OBJECTIVES

The objectives of the present article are to study the prevalence of CVD risk factors among the individuals with traumatic lower extremity amputation and to test the validity of upper arm circumference (UAC) as an alternative anthropometric measurement for screening the CVD risk condition.

SUBJECTS AND SETTING

Anthropometric data and other cardiovascular traits data have been collected from unilateral traumatic lower extremity amputated adult males (n = 85) residing in Calcutta and adjoining areas.

RESULTS

Results show higher prevalence of cardiovascular risk factor among individuals with above-knee amputation than below-knee amputation. The receiver operating characteristics curve analysis shows significant ability of upper arm circumference to diagnose cardiovascular risk condition. The cutoff value of UAC > 26.6 cm show maximum sensitivity and specificity for the diagnosis of cardiovascular risk condition. Although, binomial tests for equality of proportion does not show any significant difference, however, agreement statistics reveal better diagnostic ability of cutoff value of UAC than the existing cutoff value of waist circumference.

CONCLUSIONS

Therefore, UAC provides a better assessment of cardiovascular risk condition than does waist circumference especially for individuals with lower extremity amputation.

Sex- and age-related variations of the somatotype in a Chuvasha population

The aim of this large, cross-sectional study was to describe the age- and sex-related variations of the somatotype, employing Heath and Carter's method, in a Chuvasha population residing in a rural region in central Russia. The investigated sample included 802 males aged 18-89 years (mean 46.9) and 738 females aged 18-90 years (mean 48.6). We evaluated the age and sex differences by one-way ANOVA with somatotype components as dependent variables and sex or age groups as grouping variables. Sex differences of somatotypes appear to be the strongest for endomorphy, with generally higher values in women. Endomorphy in males remained virtually unchanged after 30 years of age, but endomorphy in females kept increasing up to the 6th decade, and then subsequently decreased. Virtually no differences were noted in mesomorphy and a very small difference in ectomorphy between males and females aged 18-30 years. A reduction of sexual dimorphism in all somatotype components after age 70 was also observed. The largest difference of all somatotype components appeared between age groups 18-30 and 31-40 years. Thereafter, somatotypes remained practically unchanged. Mesomorphy continued to increase until the 5th decade in both sexes, while in females, endomorphy continuously increased until their 6th decade. In the 7th and 8th decades, a decrease in mean values was observed. Mesomorphy and ectomorphy showed opposite age-related trends. Results of our study clearly suggest that in physique investigations, the somatotypes need to be studied in each sex separately, and in studies of young people, they need also to be adjusted to age.

Physical Attractiveness and Health in Western Societies: A Review

Evidence from developed Western societies is reviewed for the claims that (a) physical attractiveness judgments are substantially based on body size and shape, symmetry, sex-typical hormonal markers, and other specific cues and (b) physical attractiveness and these cues substantially predict health. Among the cues that the authors review, only female waist-to-hip ratio and weight appear to predict both attractiveness and health in the claimed manner. Other posited cues--symmetry and sex-typical hormonal markers among them--failed to predict either attractiveness or health (or both) in either sex. The authors find that there is some indication that attractiveness has an overall relationship with health among women, but little indication that male attractiveness relates to male health.

Variations of Somatotype in elderly Sardinians

Somatotyping is an effective technique for the study of anthropometric variations and body composition in elderly subjects, even though it has not often been used in this field. The present study was conducted on a sample of 280 healthy Sardinians (134 men and 146 women) of age 60-89 years, subdivided into three age classes (60-69 years; 70-79 years; and 80-89 years). Somatotypes were computed according to Carter and Heath (Somatotyping-Development and Applications. Cambridge, England: Cambridge University Press; 1990). The results show a dominance of the endo- and mesomorphic components in the elderly subjects, with less development of ectomorphy than in younger individuals. In a comparison with other populations, our sample shows strong development of endomorphy and especially of mesomorphy, while ectomorphy values are generally low. Age-related variations are significant in both sexes and consist in a progressive reduction of the endomorphic component, particularly in the 80-89-year class (endomorphy in the three age classes: 6.4, 6.1, and 5.3 in men; 8.1, 7.8, and 6.8 in women). The mesomorphic component is characterized by stability (age variations: 6.4, 6.4, and 5.9 in men; 6.3, 6.4, and 6.3 in women) and the ectomorphic component by a slight increase (age variations: 0.5, 0.6, and 0.8 in men; 0.4, 0.3, and 0.5 in women). Sex differences are significant and especially large for the endomorphic component, with generally higher values in women. The sexual dimorphism tends to decrease with age. The results are discussed with regard to the biology of aging, with emphasis on the potential application of somatotype to studies of the elderly population.

Evolution of life-history trade-offs in mate attractiveness and health: Comment on Weeden and Sabini (2005)

J. Weeden and J. Sabini's finding of small to no relation between traits rated as attractive in a mate and health of that mate might be interpreted as consistent with C. Darwin's (1859) proposal that these traits are arbitrary signs of beauty. However, such a conclusion would be premature. A combination of consistent empirical findings with nonhuman species and theoretical reasons argues for a continued search for honest signals of genetic fitness and reproductive health in human mate choices. Moreover, (a) even quite small relationships can be important when viewed across generations, and (b) traits that make a potential mate attractive at one age can result in poor health or early death at a later age. These life-history trade-offs greatly complicate the empirical study of attractiveness-health relations, and their potential importance has been underestimated by J. Weeden and J. Sabini.

Association between physique characteristics and hand skeletal aging status

The aim of the present study was to evaluate the association between skeletal aging traits (obtained from evaluation of hand radiographs) and physique characteristics, including indices of obesity, skeletal size, muscular development, and the somatotypes of Heath and Carter (1967) and of Deriabin (1985). To achieve our aims, we used multiple regression analysis, and Pearson's and canonical correlation analyses. The studied population comprised 629 males and 561 females aged 18-90 years, all members of the Chuvasha (Russian Federation). The present study provides evidence for a connection between hand bone aging traits and physique characteristics. The cortical index showed a small but significant correlation with adiposity and the index of overall physique, but bone mineral density (BMD) traits were not correlated with the index of overall physique. Deriabin's set of somatotypes was significantly correlated with BMD, but could explain only 2% of its variation. Significant correlations of the hand osteoarthritis trait were observed with indices of adiposity. Also observed were statistically significant canonical correlations with both sets of somatotypes, which enabled us to predict 2-3% of hand osteoarthritis variation by a combination of somatotype components. Osseometric score evinced statistically significant correlations with most indices of physique as well as with a combination of somatotype components. These findings may prove helpful in epidemiological studies, because they show that body composition is the factor that is statistically significantly associated with skeletal aging.

Somatic characteristics and cardiovascular risk factors in growth hormone deficiency: A randomized, double-blind, placebo-controlled study of the effect of treatment with recombinant human growth hormone

The purpose of the present study was to identify the effect of treatment with recombinant human growth hormone (rhGH) on seven somatic characteristics and eight clinical cardiovascular risk factors. Twenty-seven male and 24 female patients between the ages of 21 and 60 years were examined. The investigation was a double-blind, placebo-controlled study of 12 months duration. Patients were assigned randomly to treatment (T) and placebo (P) groups. In the first 6 months group T received rhGH and group P placebo. In the second 6 months both groups received rhGH. Complete data were available for 23 males and 20 females. Increments were calculated between 6 months -BL (increment 1) and 12-6 months (increment 2) in both T and P groups. Apart from the somatotype, data were analysed with a 2 x 2 mixed analysis of variance (ANOVA) using treatment (rhGH and placebo) and time (increments 1 and 2). Somatotype data were analysed using a 2 x 3 multivariate ANOVA. Three significant interactions were identified in males: waist circumference (P = 0.006), trunk fat (P = 0.0001), and conicity index (P = 0.001). The only significant interaction in females was trunk fat (P = 0.006). In general, treatment and placebo groups responded differently by time and treatment. Responses were similar in males and females. In the first 6 months when group P was on placebo, waist circumference, trunk fat, and conicity index increased slightly; with group T on rhGH somatic variables declined markedly. In the second 6 months when both groups received rhGH there was a marked decline in group P and a continued decline (but less steeply) in group T. In males there were significant decreases in endomorphy in group T and increases in mesomorphy in group P. In females the somatotype remained stable. There were no significant interactions in clinical cardiovascular risk factors in either males or females. Favourable responses occurred in male and female lipid profiles, although these were not significant. It was concluded that in males waist circumference, trunk fat, conicity index, and somatotype responded significantly to treatment with rhGH; in females the only significant response was trunk fat.
