Cultivating Vitality: Unveiling the Transformative Effects of Exercise on Menopausal Women's Well-being and Physiological Markers: A Meta-Analysis of Randomized Control Trial

Introduction: Menopause frequently coincides with age-related hormonal decline, elevated blood pressure, and unfavorable body composition changes, collectively heightening the risk of cardiovascular disease. Addressing the adverse effects of menopause is crucial through the integration of suitable lifestyle interventions, such as exercise. Nonetheless, there remains controversy within studies regarding the significance of exercise in improving Quality of Life (QoL), reducing Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP), Total Cholesterol (TC), and Low-Density Lipoprotein (LDL), as well as maintaining Bone Mineral Density (BMD). Thus, this review aims to determine and clarify the influence of exercise on patient outcomes. Materials/Methods: This meta-analysis followed the PRISMA statement guidelines, utilizing databases such as PubMed, ScienceDirect, and Google Scholar over the past ten years. Inclusion criteria adhered to the PICOS framework, and the literature quality assessment was based on the Risk of Bias 2.0 Tool. Results: Out of 14 included studies, the majority indicated no significant improvements in menopause women undergoing exercise regarding QoL [MD: -6.62 (95% CI: -16.90 – -3.66, I2=91%)], SBP [MD: -4.74 (95% CI: -10.54 – 1.05, I2=100%)], DBP [MD: -4.52 (95% CI: -8.59 – -0.46, I2=99%)], TC [MD: -4.06 (95% CI: -8.75 –0.64, I2=57%)], LDL [MD: -2.26 (95% CI: -7.37 – 2.86, I2=65%)], and BMD [MD: 0.06 (95% CI: -0.01 – 0.13, I2=86%)]. Significant improvements were seen only in DBP outcomes Conclusion: Menopause exercise women may effectively raise QoL, reduce SBP, DBP, TC, and LDL, also maintain BMD.

Body composition of adults with chronic intestinal failure receiving home parenteral nutrition: A descriptive cohort study.

Chronic intestinal failure (CIF) refers to the long-lasting reduction of gut function below the minimum necessary to absorb macronutrients, water, and/or electrolytes. Patients with CIF likely develop various forms of malnutrition and dehydration, yet studies that focus primarily on body composition are lacking. Therefore, this study aimed to evaluate the body composition of adult patients with CIF. This retrospective descriptive cohort study was performed at the Radboud University Medical Center, a tertiary referral center for CIF treatment in the form of home parenteral nutrition. We collected available bioelectrical impedance analysis (BIA) data from routine care between 2019 and 2023. The primary outcome was body composition, which was evaluated by assessing body mass index (BMI), fat-free mass index (FFMI), and fat percentage (fat%). Overall, 147 adult patients with CIF were included with a median (interquartile range) age of 58 (25-68) years; 69% were female. The mean (SD) BMI was 22.1 (4.3) kg/m2, FFMI was 14.2 (1.9) kg/m2 in females and 17.0 (2.0) kg/m2 in males, and fat% was 33.7% (6.8%) in females and 24.6% (6.4%) in males. 63% had an FFMI below references, and 48% had a high fat%. This study found that most adult patients with CIF have an unfavorable body composition characterized by a high fat% and low FFMI despite having a normal mean BMI. These results highlight the necessity for in-depth nutrition assessment, including BIA measurement. Moreover, future studies should focus on exercise interventions to increase FFMI and improve body composition and function.

Association between body composition phenotypes and treatment toxicity in women with cervical cancer undergoing chemoradiotherapy

ObjectiveTo identify whether there is an association between body composition phenotypes and toxicity to chemoradiotherapy in women with cervical cancer. MethodsThis is a prospective cohort study that included 330 adult patients with cervical cancer treated with chemoradiotherapy. Computed tomography images were used to assess skeletal muscle index (SMI) and radiodensity (SMD), total adipose tissue index, and visceral adipose tissue index. Chemoradiotherapy toxicity was assessed weekly, and toxicity-induced modification of treatment (TIMT) was considered as any severe adverse event resulting in treatment interruption, delay, or dose reduction. ResultsApproximately 45% of the patients presented at least one unfavorable body composition parameter (lower SMI, lower SMD, higher total adipose tissue index, or higher visceral adipose tissue index), 23% had two conditions, and 3% had three conditions. The incidence of toxicity ≥ grade 3 and TIMT was 55% and 30%, respectively. For adverse events ≥ grade 3, lower SMI was the determining factor for worse outcomes when evaluated alone or combined with lower SMD and normal adiposity. All body composition phenotypes were associated with TIMT, increasing the risk when both conditions were present. ConclusionsLower SMI was an independent factor for the higher number of adverse events, as it remained a risk factor when analyzed in isolation or in association with adipose tissue. Women with excess adipose tissue associated with lower muscle mass had a risk approximately 4 times higher of delaying or interrupting chemoradiotherapy. Furthermore, for the sum of unfavorable conditions, there was a progressive increase in the risk of TIMT.

Age and body composition of patients receiving treatment for locally advanced esophageal cancer.

e16094 Background: Standard of care for locally advanced esophageal cancer consists of chemoradiation (chemoRT) followed by esophagectomy. Fewer patients in older populations with locally advanced esophageal cancer undergo esophagectomy when compared to their younger counterparts. Furthermore, frail patients frequently forgo surgery after chemoRT. The current study examined the relationship between age, body composition, and treatment decision-making in locally advanced esophageal cancer. Methods: Patients with clinical stage T2-4, N0-2, and M0 adenocarcinoma or squamous cell carcinoma of the mid or distal esophagus diagnosed between 2010-2021 were included from 11 hospitals across our healthcare system. Treatment decision-points included receipt of chemoRT versus non-curative therapy, unresectable disease after chemoRT defined by metastatic disease or upper mediastinal lymphadenopathy, and receipt of surgery stratified by histology. Sociodemographic data including age, race, sex, insurance status, socioeconomic status, body composition data from CT imaging (skeletal muscle gauge [SMG]), and outcome data were collected. Skeletal Muscle Gauge was calculated as the product of skeletal muscle cross-sectional area at L3 normalized for height and muscle density. Fisher's exact test was used for categorical variables and Kruskal-Wallis for continuous variables. Results: 513 patients were included in the analysis, of which 399 (78%) had adenocarcinoma and 114 (22%) had squamous cell carcinoma. Median age was 66. Of the 513 patients, 472 (92%) underwent chemoRT (366 [78%] adenocarcinoma, 106 [22%] squamous cell carcinoma). Patients who were over the age of 75 were less likely to undergo chemoRT when compared to their younger counterparts (85% vs. 94%, p = 0.002). After the completion of chemoRT, 419 (89%) patients were deemed resectable, 330 adenocarcinoma and 89 with squamous cell carcinoma. Among resectable patients with adenocarcinoma, those > 75 years old and lower SMG were less likely to receive surgery (p < 0.001 and p =0.001). Age and body composition associated with lower receipt of surgery in locally advanced esophageal cancer patients was significant on both univariate and multivariate analyses. Conclusions: Patients over 75 are less likely to undergo chemoRT and surgical resection for locally advanced esophageal cancer. Among patients with resectable disease who have completed chemoRT, those with unfavorable body composition as measured by low SMG on CT imaging are also less likely to undergo surgical resection. These measures may be helpful in surgical decision-making in patients with locally-advanced esophageal cancer. Further study is warranted to more precisely define the relationship between age, body composition, and risk of surgery in esophageal cancer.

Abstract PO1-11-11: A Novel Body Composition Risk Score (B-Score) and Overall Survival among Patients with Early-Stage Breast Cancer

Abstract Background: Measurements (amount, distribution, and radiodensity) of muscle and adipose tissue were reported to be individually associated with overall survival in breast cancer survivors, but they were not typically combined to develop an overall risk score. Such a score can identify patients at high risk of death and prioritize patients in need of lifestyle interventions. Objectives: We developed a novel body composition risk score (B-Score) by combining multiple tissue measurements. Methods: We included 3105 patients with stage II or III breast cancer (diagnosed from 2000 to 2013) at Kaiser Permanente Northern California and Dana Farber Cancer Institute. From CT scans at diagnosis, we used the third lumber vertebrae as the landmark to assess areas (cm2) and radiodensity (HU) of muscle and adipose tissue. We divided the area by height2 (m2) to derive the index and measured the average HU of the tissue area as the radiodensity, which acts as a marker of tissue 'quality' to be indicative of lipid content, inflammation, and angiogenesis. Out of all tissue measurements, we considered skeletal muscle index (SMI), subcutaneous adipose tissue index (SATI) and SAT radiodensity as they were independent predictors for overall survival. Each measurement was dichotomized using optimal stratification, with low SMI (< 40.1cm2/m2), high SATI (≥75.7cm2/m2), and high SAT radiodensity (≥ -97.2HU) considered risk factors. We calculated B-Score as the sum of these factors and estimated its association with overall survival using Cox proportional hazards regression with adjustment for clinicopathologic factors. Results: Mean (standard deviation) age at diagnosis was 53.9 (11.8) years, 2161 (70.1%) were Non-Hispanic White, 1880 (60.5%) were stage II, and 919 (29.6%) died over a median follow-up of 10.7 years. Most patients (60.6%) had only one body composition risk factor (B-Score = 1). Compared to those with no body composition risk factors (B-Score = 0), the risk of death increased with more body composition risk factors: the adjusted hazard ratios were 1.10 (95% CI: 0.85, 1.42), 1.47 (95% CI: 1.12, 1.92), and 2.11 (95% CI: 1.26, 3.53) for B-Scores of 1, 2, and 3, respectively (Ptrend < 0.001). Conclusions: More unfavorable body composition characteristics were associated with increased risks of overall mortality in a dose-response manner. Considering body composition measurements together as a composite score (B-Score) may prove a useful tool to identify patients at high risk of death following breast cancer diagnosis. Table. Adjusted Associations of the Body Composition Risk Score (B-Score) with Overall Mortality Among Patients with Early-Stage Breast Cancer Abbreviations: HR, hazard ratio. a Areas (cm2) and radiodensity (HU) of skeletal muscle and subcutaneous adipose tissue (SAT) were extracted from the single axial CT slice at the third lumbar vertebra. The body composition risk score was defined as the sum of three risk factors: low skeletal muscle index (SMI; <40.1cm2/m2), high SAT index (SATI; ≥75.7cm2/m2), and high SAT radiodensity (≥ -97.2HU). b Adjusted for age (years), race and ethnicity (Asian, Black, Hispanic, Non-Hispanic White, and Others), stage (II, III), ER (ER+, ER-), PR (PR+, PR-), HER2 (HER2+, HER2-, unknown), smoking (current, former, never), Charlson comorbidity index (0, 1-2, ≥3), and BMI (<18.5, 28.5-24.9, 25-29.9, and ≥30 kg/m2). For the trend test, B-Score was considered as a continuous variable with adjustment for the above covariates.

Early life poly- and perfluoroalkyl substance levels and adiposity in the first 2 years of life.

Poly- and perfluoroalkyl substances (PFASs) are nondegradable, man-made chemicals. They accumulate in humans with potential harmful effects, especially in susceptible periods of human development, such as the first months of life. We found that, in our cohort, exclusively breastfed (EBF) infants had 3 times higher PFAS plasma levels compared with exclusively formula-fed (EFF) infants at the age of 3 months. Thus, PFASs could potentially reduce the health benefits of breastfeeding. We investigated the associations between PFAS levels at the age of 3 months and accelerated gain in fat mass during the first 6 months of life, body composition at 2 years, and whether these associations differ between EBF and EFF infants. In 372 healthy term-born infants, we longitudinally assessed anthropometrics, body composition (by air-displacement plethysmography and dual-energy X-ray absorptiometry), and visceral and subcutaneous fat (by abdominal ultrasound) until the age of 2 years. The plasma levels of 5 individual PFASs were determined by liquid chromatography-electrospray ionization-tandem mass spectrometry at the age of 3 months. We studied associations between PFAS levels and outcomes using multiple regression analyses. Higher early life plasma perfluorooctanoic acid and total PFAS levels were associated with an accelerated gain in fat mass percentage [FM%; >0.67 SD score (SDS)] during the first 6 months of life. Higher early life PFAS levels were associated with lower fat-free mass (FFM) SDS at the age of 2 years, but not with total FM% SDS at 2 years. Furthermore, we found opposite effects of PFAS levels (negative) and exclusive breastfeeding (positive) at the age of 3 months on FFM SDS at 2 years. Higher PFAS levels in early life are associated with accelerated gains in FM% during the first 6 months of life and with lower FFM SDS at the age of 2 years, which have been associated with an unfavorable body composition and metabolic profile later in life. Our findings warrant further research with longer follow-up times.

Biologically Informed Polygenic Scores for Brain Insulin Receptor Network Are Associated with Cardiometabolic Risk Markers and Diabetes in Women.

To investigate associations between variations in the co-expression-based brain insulin receptor polygenic score and cardiometabolic risk factors and diabetes mellitus. This cross-sectional study included 1,573 participants from the Helsinki Birth Cohort Study. Biologically informed expression-based polygenic risk scores for the insulin receptor gene network were calculated for the hippocampal (hePRS-IR) and the mesocorticolimbic (mePRS-IR) regions. Cardiometabolic markers included body composition, waist circumference, circulating lipids, insulin-like growth factor 1 (IGF-1), and insulin-like growth factor-binding protein 1 and 3 (IGFBP-1 and -3). Glucose and insulin levels were measured during a standardized 2-hour 75 g oral glucose tolerance test and impaired glucose regulation status was defined by the World Health Organization 2019 criteria. Analyzes were adjusted for population stratification, age, smoking, alcohol consumption, socioeconomic status, chronic diseases, birth weight, and leisure-time physical activity. Multinomial logistic regression indicated that one standard deviation increase in hePRS-IR was associated with increased risk of diabetes mellitus in all participants (adjusted relative risk ratio, 1.17; 95% confidence interval, 1.01 to 1.35). In women, higher hePRS-IR was associated with greater waist circumference and higher body fat percentage, levels of glucose, insulin, total cholesterol, low-density lipoprotein cholesterol, triglycerides, apolipoprotein B, insulin, and IGFBP-1 (all P≤0.02). The mePRS-IR was associated with decreased IGF-1 level in women (P=0.02). No associations were detected in men and studied outcomes. hePRS-IR is associated with sex-specific differences in cardiometabolic risk factor profiles including impaired glucose regulation, abnormal metabolic markers, and unfavorable body composition in women.

A novel body composition risk score (B-Score) and overall survival among patients with nonmetastatic breast cancer

Measurements (amount, distribution, and radiodensity) of muscle and adipose tissue were reported to be individually associated with overall survival in patients with breast cancer. However, they were not typically combined to develop an overall risk score, which can identify patients at high risk of death and prioritize patients in need of dietary and lifestyle interventions. Thus, we aimed to develop a novel composite body composition risk score (B-Score). We included 3105 patients with stage II or III breast cancer at Kaiser Permanente Northern California and Dana Farber Cancer Institute. From CT scans at diagnosis, we assessed areas and radiodensity of muscle and adipose tissue at the third lumber vertebrae. We considered skeletal muscle index (SMI), subcutaneous adipose tissue index (SATI) and SAT radiodensity as they were independent prognostic factors for overall survival. Each measurement was dichotomized using optimal stratification, with low SMI (<40.1cm2/m2), high SATI (≥75.7cm2/m2), and high SAT radiodensity (≥-97.2HU) considered risk factors. We calculated B-Score as the sum of these factors and estimated its association with overall survival using Cox proportional hazards regression with adjustment for clinicopathologic factors. Mean (standard deviation) age was 53.9 (11.8) years, 70.3% were Non-Hispanic White, and 60.5% were stage II. Most patients (60.6%) had only one body composition risk factor (B-Score=1). Compared to those with no risk factors (B-Score=0), the risk of death increased with more body composition risk factors: the adjusted hazard ratios were 1.10 (95% CI: 0.85, 1.42), 1.47 (95% CI: 1.12, 1.92), and 2.11 (95% CI: 1.26, 3.53) for B-Scores of 1, 2, and 3, respectively (Ptrend < 0.001). More unfavorable body composition characteristics were associated with increased risks of overall mortality in a dose-response manner. Considering body composition measurements together as a composite score (B-Score) may improve risk stratification and inform dietary and lifestyle interventions following breast cancer diagnosis.

Association between Controlling Nutritional Status (CONUT) Score and Body Composition, Inflammation and Frailty in Hospitalized Elderly Patients.

a total of 361 patients were retrospectively recruited and divided into three groups based on the CONUT score. patients with a score ≥5 exhibited significantly higher levels of inflammatory markers, such as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), Neutrophil/Lymphocytes ratio (NLR), main platelet volume (MPV), and ferritin, compared to those with a lower score. Furthermore, these patients showed unfavorable changes in body composition, including a lower percentage of skeletal muscle mass (MM) and fat-free mass (FFM) and a higher percentage of fatty mass (FM). A positive correlation was found between the CONUT score and inflammatory markers, Geriatric Depression Scale Short Form (GDS-SF), and FM. Conversely, the Mini Nutritional Assessment (MNA), Mini-Mental Status Examination, activity daily living (ADL), instrumental activity daily living (IADL), Barthel index, FFM, and MM showed a negative correlation. Frailty was highly prevalent among patients with a higher CONUT score. The receiver operating characteristic (ROC) curve demonstrated high accuracy in identifying frail patients (sensitivity). a high CONUT score is associated with a pro-inflammatory status as well as with unfavorable body composition. Additionally, it is a good tool to identify frailty among hospitalized elderly patients.

Nedostatak hormona rasta kod odraslih - dijagnoza i lečenje

Growth hormone deficiency (GHD) in adults is a rare clinical syndrome with an incidence of 1.4-4.2 per 100,000 persons per year and a prevalence of 350/million. It is characterized by unfavorable body composition, reduced muscle, and bone mass, lower capacity to endure physical effort, abnormal lipid profile, increased cardiovascular risk and poor quality of life. Despite these clinical manifestations, GHD is often unrecognized, so its diagnosis is often missed or delayed. The reason is the non-specific and subtle clinical characteristics, which require the testing of growth hormone (GH) secretion with stimulation tests. Two tests are in use, the insulin tolerance test and the glucagon test, which require the experience of the team performing them. Recently, an oral secretagogue of growth hormone - macimorelin has been used, which is simple test to perform and is safe for the patient. Insufficient secretion of GH in adults can be manifested as isolated or in combination with deficits of other pituitary hormones. However, GH is the most frequently detected hormonal deficit in adults as part of hypopituitarism. Causes of GHD can be congenital or acquired. Congenital reasons are the result of disorders of the embryogenic development of the pituitary gland and hypothalamus, and acquired are the most common complications of tumors of the sellar region and head trauma. Patients with GHD have an increased mortality rate compared to the general population. The causes of the shortened life span of these patients depend on the etiology of hypopituitarism, the applied therapy of tumors of the hypothalamus/pituitary region (surgery, radiotherapy), and the replacement of other missing pituitary hormones. During the last two decades, growth hormone therapy in adults has entered routine clinical practice. The beneficial effects of this substitution are reflected in the body composition, skeletal system, metabolic status, and improvement of the quality of life. GH replacement in adults returns the mortality rate to that expected for age in the general population. Due to the known proliferative, angiogenic, and anti-apoptotic properties of GH, there is still some caution regarding the recurrence of hypopituitarism-causing tumors or the appearance of new tumors during GH replacement. However, large and long-term follow-up studies of adults on GH therapy have shown a high safety profile of this treatment. Daily injections of GH were until recently the only way of its application, and now longacting weekly forms have been marketed, which will significantly improve adherence to this therapy.

Prevalence of Obesity and Lifestyle Risk Factors Following Two Years' COVID-19 Related Service Closure at Wellness Center, Primary Health Care.

COVID-19 lockdown has affected health behaviors and daily life in unprecedented ways. This study aimed to assess (i) the prevalence of lifestyle behaviors including physical activity, sedentary behavior, sleep, and stress levels during the COVID confinement, and (ii) evaluate anthropometric measures, body composition, cardiopulmonary and muscular endurance among regular Wellness Center attendees, following two years' service closure. A cross-sectional study was undertaken between 1st June 2022 and 30th January 2023. A structured validated questionnaire was utilized to retrospectively collect data related to the closure period, and quantitative objective measurements were obtained at the time of data collection. A total of 100 adults with a mean age of 49.6 ± 10.5 years, mostly female (80%) and Qatari (76%) participated in the study. The results revealed high rates of low physical activity (47%), sedentary behavior (62%), poor sleep (58%), and stress levels (61% moderate and 5% high). Results also confirmed high prevalence of obesity (57%) marked by BMI and body circumferences, fat mass (34 ± 10.5 kg)/fat percentage (42.7 ± 7.2%) and muscle mass (20.6 ± 5.4 kg)/muscle percentage (25.4 ± 3.9%) above and below normal levels, respectively. The average cardiopulmonary (mean VO2 MAX was 15.5 ± 11 mL O2kg-1min-1) and muscular endurance (pushups per min 19 ± 8.9, L-sit 46 ± 35 secs, plank 42.7 ± 27.8 secs) were distinctly below normal levels for age and sex. The findings indicate that physically active adults have experienced adverse lifestyle behaviors during the COVID-19 lockdown. Obesity, unfavorable body composition, low cardiopulmonary and muscular endurance were evident. More emphasis should be put on the development of targeted intervention strategies to promote positive lifestyle behaviors during any potential future crises.

FRI186 Differences Of Body Composition And Comorbidities In Patients With Primary Aldosteronism According To Sex And Subtypes

Abstract Disclosure: S. Park: None. C. Ahn: None. S. Seo: None. S. Kim: None. J. Yoon: None. J. Kim: None. Background: Primary aldosteronism (PA) is associated with metabolic risks such as diabetes and obesity. However, controversy exists as to which subtype of PA has a higher metabolic risk between idiopathic hyperaldosteronism (IHA) and aldosterone-producing adenoma (APA). We aimed to assess the body composition of two PA subtypes according to sex and evaluate autonomous cortisol secretion (ACS) and its contribution to comorbidities. Methods: A total of 400 patients with PA and 1:10 age- and sex-matched healthy controls (n=4,000) were enrolled. Clinical and biochemical data were reveiwed. The skeletal muscle area (SMA), subcutaneous fat area, and visceral fat area (VFA) at the third lumbar spine were calculated using abdominal computed tomography-based body composition analysis. Results: In both sexes, a higher body mass index (BMI) was observed in patients with IHA than in those with APA (P&amp;lt;0.001 in men and P=0.049 in women). Hemoglobin A1c (HbA1c) level and the prevalence of diabetes were higher in female patients with IHA than in those with APA (6.0±0.9 vs. 5.6±0.5%, P=0.005 for HbA1c; 19.0% vs. 6.8%, P=0.016 for diabetes). The VFA/BMI ratio was significantly higher in patients with IHA than in patients with APA (5.77±2.69 vs. 4.56±2.35, P&amp;lt;0.001 in men; 4.03±2.58 vs. 2.53±2.05, P&amp;lt;0.001 in women). In subgroup analysis, decreased SMA was observed in PA patients with ACS compared with those without ACS. Compared with age- and sex-matched healthy controls, all patients with IHA and female patients with APA showed significantly higher VFA and VFA/BMI. Conclusion: Patients with IHA were more obese and had higher visercal adiposity than those with APA. This metabolically unfavorable body composition may contribute to a higher metabolic risk in patients with IHA. The role of adipose tissue in pathogenesis of IHA remains to be elucidated.

Mechanisms of improved body composition among perimenopausal women practicing Meditative Movement: a proposed biobehavioral model.

Weight gain and unfavorable body composition are prevalent among midlife/older women throughout menopause. These shifts may negatively impact health, well-being, and longevity. Efforts to attenuate weight and body composition changes are traditionally driven by manipulation of diet and/or exercise; however, sustained results are limited, possibly because the full spectrum of biobehavioral systems is not addressed by diet and exercise alone. We propose a biobehavioral model detailing mechanisms of body composition decline among perimenopausal women and the associated components of Meditative Movement (ie, tai chi, qigong, yoga) that address each of these factors. Based on our previous work and extensive review of the literature, we developed a multifactorial and multidimensional biobehavioral model including factors that most directly relate to body composition among perimenopausal women: 1) psychological (ie, stress and mood, mindfulness and self-compassion, body awareness), 2) behavioral (ie, sleep, physical activity, eating behaviors), and 3) physiological (ie, cortisol, estrogen). Relationships between each factor, Meditative Movement practice components, and predicted effects on body composition were explored in detail. Our model describes select psychological, behavioral, and physiological factors, and potential mechanistic pathways of Meditative Movement practice driving improved changes in body composition and weight outcomes for perimenopausal women. The proposed model details a novel, evidence-supported means to reduce the risk of deleterious shifts in body composition throughout perimenopause and menopause thereafter. We suggest that these changes may occur directly and/or indirectly through psychological, behavioral, and physiological mechanisms that facilitate the desired changes in body composition.

Nutritional Strategies to Improve Meat Quality and Composition in the Challenging Conditions of Broiler Production: A Review.

Poultry meat is becoming one of the most important animal protein sources for human beings in terms of health benefits, cost, and production efficiency. Effective genetic selection and nutritional programs have dramatically increased meat yield and broiler production efficiency. However, modern practices in broiler production result in unfavorable meat quality and body composition due to a diverse range of challenging conditions, including bacterial and parasitic infection, heat stress, and the consumption of mycotoxin and oxidized oils. Numerous studies have demonstrated that appropriate nutritional interventions have improved the meat quality and body composition of broiler chickens. Modulating nutritional composition [e.g., energy and crude protein (CP) levels] and amino acids (AA) levels has altered the meat quality and body composition of broiler chickens. The supplementation of bioactive compounds, such as vitamins, probiotics, prebiotics, exogenous enzymes, plant polyphenol compounds, and organic acids, has improved meat quality and changed the body composition of broiler chickens.

Reproductive hormones, bone mineral content, body composition and testosterone therapy in boys and adolescents with Klinefelter syndrome.

Adult patients with Klinefelter syndrome (KS) are characterized by a highly variable phenotype including tall stature, obesity and hypergonadotropic hypogonadism as well as an increased risk of developing insulin resistance, metabolic syndrome, and osteoporosis. Most adults need testosterone replacement therapy (TRT), whereas the use of TRT during puberty has been debated. In this retrospective, observational study reproductive hormones and whole-body dual-energy X-ray absorptiometry (DXA) derived body composition and bone mineral content were standardized to age-related standard deviation scores (SDS) in 62 patients with KS aged 5.9 to 20.6 years. Serum concentrations of total testosterone and inhibin B were low, whereas LH and FSH were high in patients before TRT. Despite normal body mass index (BMI), body fat% and ratio between android fat% and gynoid fat% were significantly higher in the entire group irrespective of treatment status. In patients evaluated before and during TRT a tendency towards a more beneficial body composition with a significant reduction in ratio between android fat% and gynoid fat% during TRT was found. Bone mineral content (BMC) did not differ from the reference, but BMC corrected for bone area was significantly lower when compared to the reference. This study confirms that patients with KS have an unfavorable body composition and an impaired bone mineral status already during childhood and adolescence. Systematic studies are needed to evaluate whether TRT during puberty will improve these parameters.

Herein, we characterize changes in body composition over one year after RCx and determine predictors of unfavorable change in radiographic nutritional indices. METHODS: CT images for 843 RCx patients from 2009-2017 were collected at baseline, 3 months, and 1 year. Artificial intelligence algorithms extracted two-dimensional axial skeletal muscle and adipose areas at the L3 level. Skeletal muscle index (SMI) and fat mass index (FMI) were calculated, and multivariable logistic regression models were performed to determine factors associated with unfavorable body composition change: absolute top tertile change in FMI and SMI. RESULTS: Muscle and fat body parameters decreased from baseline to 3 months but increased from 3 months to 1 year (Figure 1). However, the distributions of changes in SMI and FMI across these timepoints (Figure 2) show that some patients were able to maintain muscle and fat mass after surgery. In the first 3 months, increasing age and higher BMI were associated with greater loss in FMI (odds ratio (OR) < 1, p<.05); while neoadjuvant chemotherapy was associated with increased gains (OR 1.5, p=.03). After 3 months, robotic surgery was associated with greater gains in FMI (OR 1.8, p=.03). In the first 3 months, on multivariable analysis, men (OR 2.06), increasing BMI (OR 1.08), neoadjuvant chemotherapy (OR 3.98), and any 30-day complications (OR 1.79) were associated with greater loss in SMI from baseline to 3 months (p<.05 for all). After 3 months, older patients had smaller gains in SMI (p<.05), as did patients with bladder cancer recurrences (p<.05). On the contrary, patients with continent diversion were associated with greater gains in SMI (p<.05). CONCLUSIONS: Long-term changes in body composition after RCx are common, and clinically relevant predictors of unfavorable body composition change were identified indicating a catabolic state. Individualized rehabilitation interventions based on these predictors warrants further study.

Parent-Offspring Associations in Body Composition: Findings From the Southampton Women's Survey Prospective Cohort Study.

Children born to parents who are overweight or obese have a high risk of adult obesity, but it is unclear if transgenerational associations relating to unfavorable body composition differ by parent. To examine differential mother-offspring and father-offspring associations in body composition in early childhood. A total of 240 mother-father-offspring trios from a prospective UK population-based pre-birth cohort (Southampton Women's Survey) were included for anthropometry and dual-energy x-ray absorptiometry assessment of whole-body-less-head body composition in the offspring at 3 different ages (4, 6-7, and 8-9 years) and in the mother and father at the 8- to 9-year offspring visit. Associations were assessed using linear regression adjusting for the other parent. Positive associations between mother-daughter body mass index (BMI) and fat mass were observed at ages 6 to 7 (BMI: β = .29 SD/SD, 95% CI = .10, .48; fat mass β = .27 SD/SD, 95% CI = .05, .48) and 8 to 9 years (BMI: β = .33 SD/SD, 95% CI = .13, .54; fat mass β = .31 SD/SD, 95% CI = .12, .49), with similar associations at age 4 years but bounding the 95% CI. The mother-son, father-son, and father-daughter associations for BMI and fat mass were weaker at each of the ages studied. A strong association between the fat mass of mothers and their daughters but not their sons was observed. In contrast, father-offspring body composition associations were not evident. The dimorphic parent-offspring effects suggest particular attention should be given to early prevention of unfavorable body composition in girls born to mothers with excess adiposity.

Well-being predictors of body composition and associated behavioral risk factors in midlife/older women participating in a meditative movement intervention: an exploratory analysis.

Greater than 40% of women are obese, a key risk factor for cardiometabolic, neurocognitive disease, mood disorders, and certain cancers. Obesity and unfavorable body composition can compromise physical and psychological health and well-being. Preliminary evidence demonstrates Meditative Movement (i.e., Tai Chi Easy) improves health outcomes and body composition among midlife/older women. This single-group pilot study explored relationships between well-being predictors related to body composition and associated behavioral risk factors in midlife/older women pre-to-post Tai Chi Easy intervention. Eligible women 45-75 years old, participated in once-weekly 30-minute Tai Chi Easy classes over 8-weeks. Pre/post-intervention data included self-report surveys and on-site body composition. Multivariate linear regression models were fitted with putative predictor variables having correlations p-values of 0.20 or less with sleep quality and eating behaviors. Participants (N = 36) (M age = 53.7) were White (80.4%) and attended ≥ 4 years of college (70.6%). Analyses resulted in one independent variable per model as a predictor of the dependent variables of sleep quality and emotional eating. Results indicated: (1) stress explained 13.4% sleep quality variance (F (2, 20) = 2.71, p = 0.09) and (2) self-compassion explained 42.1% emotional eating variance (F (2, 31) = 12.54, p < .01). Findings suggest stress and self-compassion partially explain variance in the dependent variables of sleep quality and emotional eating, both associated behavioral risk factors of body composition. Additional research may guide interventions to test efficacy and examine mediators to improve well-being predictors, body composition, and associated behavioral risk factors among midlife/older women.

Osteosarcopenic Adiposity and Nutritional Status in Older Nursing Home Residents during the COVID-19 Pandemic.

The aim was to evaluate body composition and prevalence of osteosarcopenic adiposity (OSA) in nursing home residents (NHR) and to assess their nutritional status. This research builds on our pilot study (conducted prior COVID-19 pandemic) that revealed high OSA prevalence and poor nutritional status in NHR. The current study included newly recruited n = 365 NHR; 296 women, 69 men, aged 84.3 ± 5.6 and 83.1 ± 7.3 years, respectively. Body composition was measured by bioelectrical impedance BIA-ACC®, yielding total bone mass along with all components of lean and adipose tissues. The Mini Nutritional Assessment-Short Form (MNA-SF) was used to assess nutritional status. Participants reported about their present/past diseases, including COVID-19. Mean duration of stay in nursing homes was 46.3 ± 47.0 months. Approximately 30% of participants had COVID-19 prior (median 6.7 months) to entering the study. OSA was diagnosed in 70.8% women and 47.8% men (p < 0.001). Malnourishment was detected in 5.8% women and 6.2% men while the risk of malnourishment was found in 30.8% women and 30.0% men. No significant differences in age, body composition parameters, prevalence of OSA, malnutrition/risk for malnutrition were found in participants who had COVID-19 compared to those who did not. Regression analysis showed that intramuscular adipose tissue (%) was significantly positively, while bone mass was significantly negatively associated with OSA. In this population, the high prevalence of OSA coincided with the high prevalence of malnutrition/risk of malnutrition. Such unfavorable body composition status is more likely a consequence of potentially poor diet quality in nursing homes, rather than of health hazards caused by COVID-19.

Co-construct, implement and evaluate an intervention to prevent a sedentary lifestyle in children

Abstract Background In children a sedentary lifestyle is associated with the development of chronic diseases, as well as unfavorable body composition and physical condition, lower levels of self-esteem, sociability, and school results. In Europe 39,8% of children (6-9 years) spend on average more than 2h/day in front of a screen, and 14,6% over 3h/day. In this context, designing and testing effective interventions to decrease sedentary behavior in children is a major public health research gap. The CIPRES intervention aims to reduce sedentary time in school-age children (7-10 years). Methods The CIPRES intervention is co-constructed with key local actors, by using a socio-ecological approach, and theory-based on the transcontextual model. The intervention is evaluated by a cluster-randomized controlled study currently ongoing. The target population is made up of 1000 children from 13 primary schools (in years 4-5) from southeast of France with different levels of social deprivation. Main outcomes are assessed by accelerometer and questionnaires before (T0) and after a six-week intervention (T1) and include sedentary behavior, physical activity (PA) and variables of the transcontextual model. Results Preliminary data were available in 152 children (53 intervention and 99 control). There was no significant difference across the time in sedentary time between intervention and control group (p = 0.11; η2=0,017); however, moderate-to-vigorous physical activity (MVPA) tended to be better in intervention vs control (p = 0.06; η2=0,023). In the intervention group, sedentary time and MVPA were significantly better across the time (p = 0.028 and p = 0.011, respectively) for children having a father with a university diploma as compared to children having a father with a lower education level. Conclusions Preliminary results on a small group of subjects (n = 152) are encouraging and suggest a positive impact of the intervention on children. More results will be available by summer 2022. Key messages • Based on the socio-ecological model, the CIPRES intervention aims to prevent sedentary in school-aged children. • Preliminary data suggests a favorable impact of the intervention on physical activity.
