RESUMO

AIMS: Less than 50% of patients treated for hypertension reach a target office systolic blood pressure (SBP). We aimed to evaluate the role of adiposity on antihypertensive drug responses in newly diagnosed hypertensive patients. METHODS: Estimated glomerular filtration rates, body mass index (BMI), skinfold thickness (SFT), body surface areas and waist circumferences of 150 hypertensive patients naïve to treatment were measured. Treatment protocols were started as combination of angiotensin converting enzyme inhibitor (ACE-I) plus calcium channel blocker (CCB), angiotensin receptor blocker plus CCB or ACE-I plus diuretic. Pre-treatment and change in blood pressure (ΔBP) after 4 weeks treatment were determined. Multiple linear regression analysis was used to find independent predictors of Δblood pressure changes, and multivariable binary logistic regression analysis to find independent predictors of target SBP < 140 mmHg at 4 weeks. RESULTS: A total of 104 patients reached the target systolic pressure of <140 mmHg at 4 weeks. Triceps, mid-abdomen and subscapular SFT were significantly thicker in the uncontrolled blood pressure group (P = .011, P = .006 and P = .016, respectively). Pretreatment SBP (r = 0.644), pretreatment diastolic blood pressure (DBP) (r = 0.188), subscapular SFT (r = -0.318), suprailiac SFT (r = -0.211) and ΔDBP (r = 0.433) were correlated with ΔSBP in correlation analysis. Pretreatment SBP (ß = 0.644, 95% CI = 0.697-0.993, P < .001), subscapular SFT (ß = -0.253, 95% CI = -0.886--0.329, P < .001), pretreatment DBP (ß = -0.380, 95% CI = -0.1001- -0.453, P = .001) and ΔDBP (ß = 0.401, 95% CI = 0.377-0.796, P < .001) were independent predictors of ΔSBP in multivariable linear regression analysis. Subscapular SFT was an independent predictor of target SBP < 140 mmHg in multivariable logistic regression analysis (OR = 0.895, 95% CI = 0.832-0.963, P = .003). CONCLUSIONS: Subscapular SFT may be a valuable marker for prediction of response to antihypertensive drugs.

RESUMO

BACKGROUND AND AIMS: The association of cardiometabolic disease (CMD) with body muscle and fat mass remains unclear. Mid-arm muscle circumference (MAMC) and triceps skinfold (TSF) thickness are easily obtained measuring methods for these two body compositions. This study aimed to investigate the association of CMD with MAMC and TSF thickness among Chinese residents. METHODS: A total of 9440 eligible participants from the China Health and Nutrition Survey were included in the analysis. Associations of CMD prevalence with MAMC and TSF thickness were estimated using logistic regression models. Multivariable COX proportional-hazards regression models were used to estimate the effect of baseline MAMC and TSF thickness on subsequent CMD. RESULTS: Positive associations of CMD prevalence with MAMC (odds ratio [OR] = 1.169, 95% confidence interval [CI] 1.110-1.232, P < 0.001) and TSF thickness (OR = 1.313, 95%CI 1.240-1.390, P < 0.001) were observed in the cross-sectional analysis. In the longitudinal study, a 1-SD increase in MAMC was associated with a 13.6% increased risk of CMD incidence (hazard ratio [HR] = 1.136, 95%CI 1.073-1.204, P < 0.001), and a 1-SD increase in TSF thickness had a 17.6% increased risk of CMD incidence (HR = 1.176, 95%CI 1.084-1.276, P < 0.001). For the CMD components, both MAMC and TSF thickness contributed to increased incidences of hypertension (HR = 1.163, 95%CI 1.097-1.233, P < 0.001 in MAMC; HR = 1.218, 95%CI 1.110-1.336, P < 0.001 in TSF thickness) and diabetes mellitus (HR = 1.166, 95%CI 1.028-1.323, P = 0.017 in MAMC; HR = 1.352, 95%CI 1.098-1.664, P = 0.004 in TSF thickness). CONCLUSIONS: Individuals with higher MAMC and TSF thickness had an increased incidence of CMD, mainly hypertension and diabetes mellitus. This study revealed a seemingly counterintuitive association between body muscle mass and metabolic homeostasis. Although the potential mechanisms require further exploration, the impact of body muscle mass on metabolic health cannot be ignored.

RESUMO

BACKGROUND: Currently, skinfold thickness in studies on arm venous access ports and the effect of venous access port application are unknown. MATERIALS AND METHODS: A total of 256 cancer patients who underwent primary venous access port placement in the Fourth Hospital of Hebei Medical University from September 2022 to March 2023 were selected as the study subjects. Two hundred fifty-six patients were divided into normal skinfold thickness group and high skinfold thickness group according to skinfold thickness. The success rate of primary catheterization of arm venous port catheterization, catheterization operation time, catheterization length and incidence rate of adverse reactions were compared. RESULTS: There was no significant difference in the basic data between the two groups. There was no significant difference in the success rate of primary catheterization between the two groups (p > 0.05), the catheterization operation time in the normal skinfold thickness group was significantly lower than that in the high skinfold thickness group (p < 0.05), the total length of the implanted catheter in the normal skinfold thickness group was significantly lower than that in the high skinfold thickness group (p < 0.05), and the incidence of adverse reactions in the normal skinfold thickness group was significantly lower than that in the high skinfold thickness group (p < 0.05). CONCLUSION: In cancer patients, skinfold thickness can significantly affect the application effect of arm venous port, and normal skinfold thickness for arm venous port has shorter operation time, total length of implanted catheter and lower incidence of adverse reactions.

RESUMO

Parental and pregnancy characteristics can affect proportions and tissue composition of the child's bodyand thereforecan influence their present and future health, as well as overall wellbeing. The aim of this study was to examine the differences between selected parental and birth-related parameters among preschool (3-7 years of age) children of varying adiposity status (n=541 girls and n=571 boys).The research was carried out in 20 randomly selected kindergartens in Krakow (Poland). Thickness of 6 skinfolds (biceps, triceps, subscapular, suprailiac, abdominal and calf) was measured. Sum of skinfolds was calculated and participants were divided into low, normal or high body fat groups. Birth-related characteristics were obtained using a questionnaire filled out by the children's parents. Children of mothers who gained the most gestational weight were characterised by high adiposity. Preschoolers with the highest birth weight, body length and head circumference had the greatest adiposity. Children of relatively younger mothers had higher body fat, in comparison to the rest of the study group. Parents of preschoolers in the high adiposity category were characterised by a greater body mass, compared to the parents of children in other body fat groups and that boys with the highest adiposity relatively more often had a close relative with obesity. Children in varying adiposity categories differed in terms of some birth-related factors. Particular attention should be paid to familial and parental characteristics, because they may influence the child's predisposition to excess adiposity deposition later in life.

RESUMO

BACKGROUND: Growth in the first year of life depends primarily on nutrition. Currently, the infant feeding practices of term babies are being extrapolated for preterms. While extrapolating, it is not clear if corrected age (CA) or chronological age should be used. In preterm infants, born ≤34 week gestation age, this difference may be more than 6 weeks. We studied the growth parameters and body composition of preterm infants born ≤34 week gestation age as compared to that of term infants at 12-13 months CA. METHODS: The growth of 99 term infants and 170 preterm infants born ≤34 weeks was evaluated at 12-13 months CA. The anthropometric measurements, body mass index (BMI) and skin fold thickness (SFT) at four sites (biceps, triceps, subscapular and suprailiac) were compared in the two groups. The sum of the SFT was taken as a marker of fat mass. RESULT: At 12-13 months CA, preterm infants had significantly less weight, length and BMI as compared to term babies. The weight and BMI for age Z-scores, weight for length Z-scores and fat mass were also significantly less in preterm babies. CONCLUSION: The anthropometry measures in preterms (<34 weeks) at 12-13 months CA were significantly lower than that of term infants. In our study population, preterms did not catch up in growth in the first year even when the CA is used for comparison. The causes could be multifactorial and need to be studied further.

RESUMO

Background: Skinfold callipers are often used in clinical practice to estimate subcutaneous adipose tissue thickness. Recently, LipoTool emerged as a potential digital system to measure skinfolds, however comparisons with competing equipment are lacking. Aim: The aim of this study was to test the agreement between two competing skinfold callipers (digital and mechanical). Methods: The sample included 22 healthy male adult participants. A certified observer measured eight skinfolds twice using different skinfold callipers (digital and mechanical). Differences between equipment were tested using Wilcoxon signed rank test The distribution of error was examined using the normality test Results: Differences between skinfold callipers were significantly in five skinfolds: triceps (Z = -3.546; P < 0.001), subscapular (Z = -3.984; P < 0.001), suprailiac (Z = 3.024; P = 0.002), supraspinale (Z = 3.885; P < 0.001), abdominal (Z z = -2.937; P = 0.003), thigh (Z = -2.224; P = 0.026) and calf (Z = -2.052; P = 0.040). Differences between callipers were constant. Conclusions: Mechanical and digital callipers tended to record different values of skinfold thickness. Clinical examination should consider equipment-related variation in fat mass estimation.

RESUMO

AIM: To ascertain to what extent it is possible to stop being obese (to normalize body mass index [BMI], waist circumference [WC] and/or body fat percentage [BFP]). DESIGN: Longitudinal observational and retrospective study. SITE: Eleven Spanish health centers. PARTICIPANTS: Men and women with BMI≥30kg/m2 (n=1246) or general obesity (GO), with WC>102cm and >88cm, respectively (n=2122) or abdominal obesity (AO) and with BFP>25% and >35%, respectively (n=2436) or excess body fat (EBF), from the PEPAF Study cohort of 4927 participants aged 20-80years. MAIN MEASUREMENTS: Data from the PEPAF study at baseline and at 6, 12 and 24months: gender, age, diagnoses of diabetes, hypertension and dyslipidemia, smoking, levels of and compliance with physical activity recommendations, maximum oxygen consumption, weigh, height, WC and three skin-folds (thoracic, umbilical and anterior thigh for men and triceps, suprailiac and anterior thigh for women). RESULTS: Of 2054 participants with any type of obesity at baseline and valid data at 2years, 240 (11.6%) had normalized all of their obesity diagnostic indexes. 19.5% (95% confidence interval (95%CI: 17.6-21.4) ceased to have EBF, 12.0% (95%CI: 10.4-13.7) ceased to have AO and 10.5% (95%CI: 8.5-12.7) ceased to have GO. CONCLUSIONS: Obesity differs from other chronic diseases in that it can be «cured¼ by normalizing the amount of body fat.

RESUMO

Background: Obesity is a multifactorial public health problem with varying effects on physical fitness determined by maximum aerobic capacity or VO2max. The relationship between body fat content and VO2max has shown varying results. The present study was planned as an experimental study to evaluate the relationship between body fat content and maximum aerobic capacity. Methods: 104 healthy Indian males [Age: 21 (4.87)years; Height: 171.4 (6.14)cm; Weight: 64.1 (8.57)kg] were evaluated for body fat content using body mass index (BMI), bioimpedance, skinfold thickness (SFT), body girth (BG) measurements, waist circumference (WC), and waist-hip ratio (WHR). Maximum aerobic capacity or VO2max for all subjects was determined indirectly from maximum heart rate achieved using an incremental treadmill protocol using Astrand and Astrand nomogram. Results: VO2max, when expressed in L/min, showed a statistically significant positive correlation with body fat irrespective of the method of estimation. VO2max, when expressed in ml/kg/min, showed negative correlation with five of the seven clinical parameters of fat estimation. Of these, a statistically significant negative correlation was seen with SFT. Conclusion: VO2max (L/min) shows a significant positive correlation with all methods of body fat estimation. VO2max (ml/kg/min) shows a significant negative correlation with skinfold thickness. Monitoring of body fat content using skinfold thickness could be studied further for its use in the early identification of young, healthy adult Indian males with low aerobic fitness.

RESUMO

Differences in physical activity (PA) might lead to long-term weight control. Studies on inverse relations between PA and changes in fatness among adolescents are limited. This paper examined the effect of PA on adolescents' changing body fatness over 5 years in Ho Chi Minh City (HCMC). Two hundred thirty-five boys and 247 girls who have had skinfold thickness measurements in the baseline survey in 2004 were selected to follow yearly. We estimated PA as the average number of accelerometers' counts/h. Slopes of triceps, sub-scapular skinfolds and BMI were calculated and classified as increasing or stable/decreasing. To assess the effects of the low level of activity (i.e. below the median of the average number of counts) on the fat gain (i.e. increasing slopes), relative risk and 95 % CI were estimated using Poisson regression. The average number of counts/h in boys (7·8) was significantly higher than that in girls (5·0) (P < 0·001). On average, active girls still gained 0·51 mm in triceps skinfold (TSF) over 5 years, while active boys lost 0·12 mm. After controlling for baseline energy intake, baseline triceps and baseline age, inactive adolescents were 1·39 times higher than active ones to increase the slope of triceps (95 % CI 1·19, 1·63). The risk ratio was 1·62 for those with more body fat at baseline. In general, inactive students gained substantially more subcutaneous fat, especially in their TSF, than more active ones. Thus, strategies to prevent adolescent obesity in HCMC should consider the important role of PA to control this problem in adolescents effectively.

RESUMO

The present study evaluated whether fat mass assessment using the triceps skinfold (TSF) thickness provides additional prognostic value to the Global Leadership Initiative on Malnutrition (GLIM) framework in patients with lung cancer (LC). We performed an observational cohort study including 2672 LC patients in China. Comprehensive demographic, disease and nutritional characteristics were collected. Malnutrition was retrospectively defined using the GLIM criteria, and optimal stratification was used to determine the best thresholds for the TSF. The associations of malnutrition and TSF categories with survival were estimated independently and jointly by calculating multivariable-adjusted hazard ratios (HR). Malnutrition was identified in 808 (30·2 %) patients, and the best TSF thresholds were 9·5 mm in men and 12 mm in women. Accordingly, 496 (18·6 %) patients were identified as having a low TSF. Patients with concurrent malnutrition and a low TSF had a 54 % (HR = 1·54, 95 % CI = 1·25, 1·88) greater death hazard compared with well-nourished individuals, which was also greater compared with malnourished patients with a normal TSF (HR = 1·23, 95 % CI = 1·06, 1·43) or malnourished patients without TSF assessment (HR = 1·31, 95 % CI = 1·14, 1·50). These associations were concentrated among those patients with adequate muscle mass (as indicated by the calf circumference). Additional fat mass assessment using the TSF enhances the prognostic value of the GLIM criteria. Using the population-derived thresholds for the TSF may provide significant prognostic value when used in combination with the GLIM criteria to guide strategies to optimise the long-term outcomes in patients with LC.

RESUMO

BACKGROUND: Obesity is one of the causes of glomerular hyperfiltration. Studies on the relationship between body fat content and glomerular hyperfiltration have been limited to special children. Therefore, we aimed to evaluate the correlation between skinfold thickness, which represents body fat content, and estimated glomerular filtration rate (eGFR). METHODS: The cross-sectional study included 6655 participants (3532 boys and 3123 girls; age: 12 - 17.99 years); data was obtained from the National Health and Nutrition Examination Survey (NHANES; 2001-2010). The independent variables were subscapular skinfold thickness and triceps skinfold thickness. The dependent variable was eGFR. We used multivariate linear regression models to evaluate their associations and also performed subgroup analyses. RESULTS: After adjusting for age, standing height, race, family income, blood urea nitrogen and uric acid variables, multivariate regression analysis identified that triceps skinfold thickness and subscapular skinfold thickness were positively correlated with eGFR and glomerular hyperfiltration in boys. In subgroup analyses stratified by age and body mass index, triceps skinfold thickness was also associated with glomerular hyperfiltration in boys. There was a linear relationship between triceps skinfold thickness and eGFR in boys (ß = 0.389, P < 0.001) and girls (ß = 0.159, P = 0.0003). CONCLUSIONS: Triceps skinfold thickness and subscapular skinfold thickness are positively correlated with eGFR and glomerular hyperfiltration in US male adolescents. In all adolescents, there is a linear relationship between triceps skinfold thickness and eGFR.

RESUMO

BACKGROUND: Kinanthropometry offers to exercise and health professionals a standardized procedure of acquiring surface anatomical measurements that might be used to track changes in body composition. AIM: To describe simple anthropometric indices to monitor body composition changes in amateur and elite athletes, and to provide reference values during the competition phase. METHODS: A search of articles indexed in PubMed/MEDLINE, ScienceDirect, Cochrane, and SciELO databases using the string body composition AND (anthropometric OR skinfolds OR circumferences OR girth OR estimation equation) AND "body fat". Inclusion criteria were: quantitative and/or qualitative research published between 2009 and 2020, written in English or Spanish, reporting simple anthropometric indices that included skinfolds, girths, or basic measures in amateur and elite athletes. RESULTS: A total of 51 studies (Price's index = 66.4%) met all the inclusion criteria and were included in this scoping review. Contrary to the frequent practice, the use of a regression equation might not be accurate to evaluate body composition. To avoid this, anthropometrists should base their analysis on the absolute values of the sum of skinfolds (∑S) and related variables, such as skinfold-corrected girths and lean mass index. While not definitive, because further research is required, the practical recommendations and updated reference values in competition phase provided by this review would contribute to the accurate identification of body composition changes. CONCLUSIONS: ∑S and lean mass index have been shown to be valid for monitoring changes in fat mass and fat-free mass, respectively. More research is needed to derive the lean mass index-specific coefficient for each sports population.

RESUMO

The aim of this study was to compare whole body composition, generated by air displacement plethysmography (ADP) and dual-energy X-ray absorptiometry (DXA), and to evaluate the potential predictive value of the sum of skinfolds (∑SFT) for whole body composition, in preterm infants at term equivalent age. A convenience sample of sixty-five preterm infants with a mean (SD) gestational age of 29 (1.6) weeks was studied at term equivalent age. Fat mass measured by DXA and ADP were compared and the ability of the ∑SFT to predict whole body fat mass was investigated. There was poor agreement between fat mass percentage measured with ADP compared with DXA (limits of agreement: - 4.8% and 13.7%). A previously modeled predictive equation with the ∑SFT as a predictor for absolute fat mass could not be validated. Corrected for confounders, the ∑SFT explained 42% (ADP, p = 0.001) and 75% (DXA, p = 0.001) of the variance in fat mass percentage.Conclusions: The ∑SFT was not able to accurately predict fat mass and ADP and DXA did not show comparable results. It remains to be elucidated whether or not DXA provides more accurate assessment of whole body fat mass than ADP in preterm infants.Trial registration: NTR5311 What is Known: • Diverse methods are used to assess fat mass in preterm infants. What is New: • This study showed that there is poor agreement between dual-energy X-ray absorptiometry, air displacement plethysmography, and skinfold thickness measurements. • Our results affirm the need for consensus guidelines on how to measure fat mass in preterm infants, to improve the assimilation of data from different studies and the implementation of the findings from those studies.

RESUMO

BACKGROUND: Estimating total body fat in public hospitals using gold-standard measurements such as air displacement plethysmography (ADP), deuterium oxide dilution, or dual-energy X-ray absorptiometry (DXA) is unaffordable, and it is challenging to use skinfold thickness. We aimed to identify the appropriate substitute marker for skinfold thickness to estimate total body fat in pregnant women and infants. METHODS: The study is part of a prospective cohort study titled MAASTHI in Bengaluru, from 2016 to 19. Anthropometric measurements such as body weight, head circumference, mid-upper arm circumference (MUAC), and skinfold thickness were measured in pregnant women between 14 and 36 weeks of gestational age; while measurements such as birth weight, head, chest, waist, hip, mid-upper arm circumference, and skinfold thickness were recorded for newborns. We calculated Kappa statistics to assess agreement between these anthropometric markers with skinfold thickness. RESULTS: We found the highest amount of agreement between total skinfold thickness and MUAC (Kappa statistic, 0.42; 95 % CI 0.38-0.46) in pregnant women. For newborns, the highest agreement with total skinfold thickness was with birth weight (0.57; 95 % CI 0.52-0.60). Our results indicate that MUAC higher than 29.2 cm can serve as a suitable alternative to total skinfolds-based assessments for obesity screening in pregnancy in public facilities. Similarly, a birth weight cut-off of 3.45 kg can be considered for classifying obesity among newborns. CONCLUSION: Mid-upper arm circumference and birth weight can be used as markers of skinfold thickness, reflecting total body fat in pregnant women and the infant, respectively. These two anthropometric measurements could substitute for skinfold thickness in low- and middle-income urban India settings.

RESUMO

OBJECTIVE: The primary purpose of the current study was to establish Turkish smoothed centile charts and Lambda, Mu, Sigma (LMS) tables for four-site skinfold thickness based on a population-based sample, and secondary purpose was to elaborate a reference for the percentage of body fat. DESIGN: A cross-sectional and descriptive study was conducted between January and May 2017. Triceps, biceps and subscapular, suprailiac skinfold thicknesses were measured using Holtain skinfold caliper. Age- and gender-specific percentile values were determined with the LMS method, and body fat percentage was calculated using the Westrate and Deurenberg equation. SETTING: Afyonkarahisar province in Turkey. PARTICIPANTS: The current study was conducted on 4565, 6-18-year-old students. RESULTS: The triceps, biceps and subscapular skinfolds of the girls were higher than the boys. From the age of seven, the sum of four skinfold thicknesses of the girls was more than those of the boys. This difference became more evident after the age of 12. Although fat percentages of girls showed a fluctuating change, it decreased with the age in boys. Westrate and Deurenberg equation fat percentages of girls until adolescence were lower than boys, but increased after 12 years of age and exceeded that of boys. CONCLUSIONS: The current study has provided sex- and age-specific reference values for skinfold thickness and has shown that obesity in girls is higher than in boys in schoolchildren in Afyonkarahisar. The current study has also shown that skinfold thickness measurements are a valuable tool for screening obesity in children.

RESUMO

Background & objectives: A etiologically symmetric and asymmetric small for gestational age (SGA) infants are two distinct entities. In view of absence of longitudinal information on growth pattern of skinfold thicknesses (SFTs) among Indian infants, this study was conducted to assess the auxological dynamics of SFTs (sub-cutaneous fat) of symmetric and asymmetric SGA infants. Methods: Triceps, sub-scapular, biceps, mid-axillary and anterior thigh SFTs among full-term, 100 symmetric SGA, 100 asymmetric SGA and 100 appropriate for gestational age (AGA) infants were measured at one, three, six, nine and 12 months. Ponderal Index (PI) was used to categorize infants into symmetric SGA (PI ≥2.2 g/cm3) and asymmetric SGA (PI <2.2 g/cm3). Intra-group (symmetric vs. asymmetric), inter-group (SGA vs. AGA) and gender differences were quantified. Results: SFTs among symmetric, asymmetric SGA infants increased to attain peak by six months. Maximum fat deposition in SGA infants was noticed for triceps, minimum for mid-axillary SFT. Mean triceps and sub-scapular skinfolds were measured higher in symmetric SGA than in asymmetric infants. SGA infants had significantly (P≤0.05) thinner SFTs than AGA. Growth velocity for SFTs, among symmetric and asymmetric SGA, was measured maximum between one and three months, threreafter it declined and relatively, steepness of fall was maximum for mid-axillary SFT followed by sub-scapular SFT. Interpretation & conclusions: Thinner SFTs obtained for symmetric and asymmetric SGA as compared to AGA infants reveal their compromised adiposity and nutritional status. Comparatively, higher SFTs in symmetric than in asymmetric SGA infants appear to suggest that the former have a tendency to accumulate more fat, than the latter during infancy.

RESUMO

OBJECTIVE: To determine the association between excess body fat, assessed by skinfold thickness, and the incidence of type 2 diabetes mellitus (T2DM) and hypertension (HT). DESIGN: Data from the ongoing PERU MIGRANT Study were analysed. The outcomes were T2DM and HT, and the exposure was skinfold thickness measured in bicipital, tricipital, subscapular and suprailiac areas. The Durnin-Womersley formula and SIRI equation were used for body fat percentage estimation. Risk ratios and population attributable fractions (PAF) were calculated using Poisson regression. SETTING: Rural (Ayacucho) and urban shantytown district (San Juan de Miraflores, Lima) in Peru. PARTICIPANTS: Adults (n 988) aged ≥30 years (rural, rural-to-urban migrants, urban) completed the baseline study. A total of 785 and 690 were included in T2DM and HT incidence analysis, respectively. RESULTS: At baseline, age mean was 48·0 (sd 12·0) years and 47 % were males. For T2DM, in 7·6 (sd 1·3) years, sixty-one new cases were identified, overall incidence of 1·0 (95 % CI 0·8, 1·3) per 100 person-years. Bicipital and subscapular skinfolds were associated with 2·8-fold and 6·4-fold risk of developing T2DM. On the other hand, in 6·5 (sd 2·5) years, overall incidence of HT was 2·6 (95 % CI 2·2, 3·1) per 100 person-years. Subscapular and overall fat obesity were associated with 2·4- and 2·9-fold risk for developing HT. The PAF for subscapular skinfold was 73·6 and 39·2 % for T2DM and HT, respectively. CONCLUSIONS: We found a strong association between subscapular skinfold thickness and developing T2DM and HT. Skinfold assessment can be a laboratory-free strategy to identify high-risk HT and T2DM cases.

RESUMO

BACKGROUND: The present study was conducted to jointly assess some specific factors related to body fat measures using a multivariate multilevel analysis in a representative sample of Iranian mid-adolescents. METHODS: This study was conducted among 2538 students (1286 boys) aged 14-20 years old, who were randomly selected among 16 public high schools by multi-stage random sampling procedure from all education districts of Shiraz, Iran. Data on demographic characteristics, family history of obesity, physical activity, socio-economic (SES) variables and screen time were collected. Height, weight, triceps (TST), abdominal (AST), and subscapular (SST) skinfold thickness were measured and their body mass index (BMI) was calculated. A multivariate multilevel approach was used to analyze the factors associated with obesity measures of the TST, AST, SST at the child and district levels. RESULTS: In this study, the prevalence of overweight and obesity was estimated to be 10.2 and 5.1%, respectively. Overall, the major portion of the total variance in TST (97.1%), AST (97.7%), and SST (97.5%) was found at the child level. The results of multivariate multilevel method revealed that being girls, having a family history of obesity, and SES were significantly associated with increasing of three body fat measures (all the p-values were less than 0.05). There were significant positive associations between moderate to vigorous physical activities with AST and SST (for AST: ß =2.54, SE = 1.40, p = 0.05; for SST: ß =2.24, SE = 1.20, p = 0.05). Compared to children in 14-16 age group, children in age group 16-18 years had less TST (ß = - 0.67, SE = 0.34, p = 0.04). Furthermore, other age groups and screen time did not play an important role in three outcome variables. CONCLUSIONS: The results showed some factors that contribute to three body fat measures. Therefore, it is necessary to develop effective interventions to prevent the effects of individual and environmental undesirable factors on childhood obesity in both family and community levels.

RESUMO

[Purpose] Whole-body electromyostimulation (WB-EMS) is an extension of the EMS application known in physical therapy. In WB-EMS, body composition and skinfold thickness seem to play a decisive role in influencing the Ohmic resistance and therefore the maximum intensity tolerance. That is why the therapeutic success of (WB-)EMS may depend on individual anatomical parameters. The aim of the study was to find out whether gender, skinfold thickness and parameters of body composition have an influence on the maximum intensity tolerance in WB-EMS. [Participants and Methods] Fifty-two participants were included in the study. Body composition (body impedance, body fat, fat mass, fat-free mass) and skinfold thicknesses were measured and set into relation to the maximum intensity tolerance. [Results] No relationship between the different anthropometric parameters and the maximum intensity tolerance was detected for both genders. Considering the individual muscle groups, no similarities were found in the results. [Conclusion] Body composition or skinfold thickness do not seem to have any influence on the maximum intensity tolerance in WB-EMS training. For the application in physiotherapy this means that a dosage of the electrical voltage within the scope of a (WB-) EMS application is only possible via the subjective feedback (BORG Scale).

RESUMO

AIMS/HYPOTHESIS: This study aimed to explore the infancy growth trajectories of 'recent' and 'earlier' offspring of mothers with gestational diabetes mellitus (OGDM), each compared with the same control infants, and investigate whether 'recent' OGDM still exhibit a classical phenotype, with macrosomia and increased adiposity. METHODS: Within a prospective observational birth cohort, 98 'earlier' OGDM born between 2001 and 2009 were identified using 75 g oral glucose tolerance testing at 28 weeks gestation, 122 recent OGDM born between 2011 and 2013 were recruited postnatally through antenatal diabetes clinics, and 876 normal birthweight infants of mothers with no history of diabetes were recruited across the full study period as the control group. All infants followed the same study protocol (measurements at birth, 3, 12 and 24 months, including weight, length and skinfold thickness indicating adiposity, and detailed demographic data). In all cases, GDM was defined using the International Association of Diabetes and Pregnancy Study Group criteria. RESULTS: Earlier OGDM had higher birthweight SD scores (SDS) than control infants. Conversely, recent OGDM had similar birthweight- and length SDS to control infants (mean ± SD, 0.1 ± 1.0 and- 0.1 ± 0.9, respectively), but lower mean skinfold thickness SDS (-0.4 ± 0.6 vs 0.0 ± 0.9; p < 0.001). After birth, earlier OGDM showed reduced gains in weight and length between 3 and 12 months. In contrast, recent OGDM had increased weight and skinfold thickness gains until 3 months, followed by reduced gains in those variables from 3 to 12 months, compared with control infants. At 24 months, recent OGDM had lower adiposity than control infants (mean skinfold thickness SDS -0.3 ± 0.7 vs 0.0 ± 0.8; p < 0.001). At all time points recent OGDM had lower growth measurements than earlier OGDM. CONCLUSIONS/INTERPRETATION: Recent OGDM showed different growth trajectories to the earlier group, namely normalisation of birthweight and reduced adiposity at birth, followed by initial rapid weight gain but subsequent reduced adiposity postnatally. While avoidance of macrosomia at birth may be advantageous, the longer-term health implications of these changing growth trajectories are uncertain.
