Absolute and adjusted hand grip strength values in obese patients. ENDOCRINOL DIAB NUTR 2025; 72:501560. [PMID: 40379598 DOI: 10.1016/j.endien.2025.501560] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/30/2024] [Revised: 11/27/2024] [Accepted: 11/28/2024] [Indexed: 05/19/2025]
Abstract
BACKGROUND Hand grip strength-measured by dynamometry-is an essential tool in nutritional assessment, particularly for detecting sarcopenia, even before weight or muscle mass loss is evident. In individuals with obesity, hand grip strength can help identify muscle weakness that may not be apparent due to high body mass. The purpose of this study is to describe the absolute and adjusted hand grip strength values for weight, height, body mass index (BMI), and appendicular skeletal muscle mass (ASMM) in obese patients. It also aims to determine the prevalence of low muscle strength in this group of patients and to compare these results with those obtained in a healthy population. METHODS Prospective observational study including patients with obesity and healthy volunteers. Absolute and adjusted hand grip strength values for weight, height, BMI and appendicular muscle mass were determined in patients with obesity and compared with the results of healthy volunteers. Muscle strength was measured by hand grip strength according to Sánchez-Torralvo, Dodds, and < -2SD cut-off points of healthy reference population. RESULTS The results obtained show that the absolute hand grip strength values are higher in healthy volunteers (30.7 ± 10.5 kg) vs patients with obesity (26.6 ± 9.7 kg); p < 0.008. As for hand grip strength values adjusted for height, weight, BMI and ASMM, they are also statistically significantly higher in healthy volunteers (18.0 ± 5.5 vs. 15.9 ± 5.4, p < 0.014; 05 ± 0.10 vs. 0.2 ± 0.06, p < 0.001; 1.4 ± 0.4 vs. 0.6 ± 0.2, p < 0.001; 1.5 ± 0.2 vs. 0.9 ± 0.3, p < 0.001). According to sex, men had significantly higher absolute and adjusted hand grip strength values in both obese patients and healthy volunteers. The prevalence of low muscle strength in patients with obesity goes from 14.5% up and 23.4% depending on the cut-off points used, being higher with those of Sánchez-Torralvo´s cut-off points. Based on sex distribution, obese men had a higher prevalence of low muscle strength with absolute hand grip strength values vs women, being these differences statistically significant only with the Sánchez-Torralvo´s cut-off points. In terms of the prevalence of low muscle strength with adjusted hand grip strength values, more variable percentages (3.2%-96.8%) were observed without clear differences across sexes. CONCLUSIONS Hand grip strength values in obese patients vary according to absolute or adjusted measurements. Obese patients have lower absolute and adjusted hand grip strength values vs the healthy population. However, more studies are needed to establish specific cut-off points for hand grip strength in patients with obesity.

Abstract
The present study aimed to determine gender differences in the hand grip strength (HGS) and to examine the relations between HGS, anthropometric characteristics, and physical activity (PA) in Greek young adults. A cross-sectional observational study of 276 students (21.5 ± 4.1 years, 122 men, 154 women) was conducted at the University of Patras, Greece. HGS was assessed via a hand-held grip strength dynamometer; body composition was determined by bioelectrical impedance analysis; and calf, mid-arm, and waist circumferences with inelastic tape. PA was assessed with the modified Baecke Questionnaire for Habitual Physical Activity (mBQHPA). The mean of HGS was 37.15 ± 11.2 kg. Men had significantly (p < 0.001) greater HGS than women. Statistically large correlation was detected between HGS and muscle mass (r = 0.73; p ≤ 0.001), gender (r = 0.6; p ≤ 0.001), mid-arm (r = 0.74; p ≤ 0.001), and calf circumference (r = 0.69; p ≤ 0.001). Results show that fat mass was a risk factor associated with HGS, found using regression analyses in both genders. However, PA was a significant associated factor only for women participants (ΟR = 0.77; 95% confidence interval [CI]: 0.17-1.38; p ≤ 0.05). In summary, the HGS of Greek physiotherapy students was associated with muscle mass, gender, mid-arm, and calf circumference.

Is there any association between migraine headache and polycystic ovary syndrome (PCOS)? A review article. Mol Biol Rep 2021; 49:595-603. [PMID: 34651295 DOI: 10.1007/s11033-021-06799-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2021] [Accepted: 10/01/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) and migraine headaches are considered to be common health problems that may share some risk factors. This study aimed to discuss the possible association between migraine headache and polycystic ovary syndrome. METHODS AND RESULTS In this narrative review, PubMed, Scopus, Web of Science, and Google Scholar were systematically searched for retrieving and summarizing published studies up to January 2021 to explore the possible interplay between migraine headache and PCOS. We discuss the possible pathways that may explain the association between migraine headaches and PCOS signs/symptoms and complications. While genetic factors have profound effects on the pathogenesis of migraine headaches, sex hormones, including estrogen and progesterone may also play an important role in inducing migraine headaches. Some disorders, such as sleep apnea, amenorrhea, and vascular disease that are more likely to occur in women with PCOS, may cause or exacerbate migraine headaches in women with PCOS. CONCLUSIONS Future comprehensive studies are needed to investigate the exact underlining mechanisms related to the association between PCOS and migraine headaches.

Abstract
BACKGROUND Handgrip strength (HGS) is used to assess muscle strength, which is an important indicator of health status in older adults. OBJECTIVE We evaluated associations of demographic, anthropometric, clinical, and nutritional factors with muscle strength in community-dwelling elderly adults. METHODS This population-based cross-sectional study employed the 2014-2015 Israeli Health and Nutrition Survey in the Elderly (n = 1039, age ≥65 y, 46.7% males, 9.9% Arabs). Trained personnel performed face-to-face interviews that focused on health and nutrition status, as well as anthropometric measurements and examinations. HGS was measured in the dominant hand 3 times using a digital grip strength dynamometer; the highest result was reported. Dietary intake data were collected using single-day 24-h recall. Multivariable logistic regressions were used to explore factors associated with low HGS (<27 kg for men and <16 kg for women). RESULTS HGS measurements were completed by 704 participants. Following adjustment for several factors, higher prevalence of low HGS was significantly associated with age (OR: 1.14; 95% CI: 1.11, 1.18), whereas decreased prevalence was associated with higher levels of education (OR: 0.55; 95% CI: 0.32, 0.94) and meeting physical activity recommendations (OR: 0.53; 95% CI: 0.31, 0.88); P < 0.05 for all. Incremental increases of 100 kcal/d in energy intake and of 1 cm in midarm circumference were associated with decreased prevalence of low HGS (OR: 0.95; 95% CI: 0.91, 0.99 and OR: 0.91; 95% CI: 0.85, 0.97, respectively; P < 0.01 for both). Associations were not found of low HGS with ethnicity, comorbidity, BMI, smoking, or alcohol consumption or with protein, carbohydrate, or fat intakes. CONCLUSION Energy intake, physical activity, midarm circumference, and education are associated with HGS in elderly Israeli adults. Further cohort studies are necessary to assess possible causal relations between these factors and HGS. Modifiable factors should be targeted in planning public health strategies for promoting a healthy aging population.

Abstract
Considerable researches on sex steroids and insulin action have suggested a mutual interaction between hyperandrogenemia and insulin resistance (IR). The objective of present study was to evaluate the androgens levels in young females with emphasis on the association of 17OHP with IR. Serum concentrations of glucose, insulin, and androgens in 80 young females were measured by standard routine procedures. Total testosterone (TT), dihydrotestosterone (DHT), dehydroepiandrosterone sulfate (DHEAS), androstenedione (ASD), and 17-hydroxyprogesterone (17OHP) levels were higher in patients with IR compared to healthy controls (p < .05). 17OHP was associated with IR and other androgens tested in young females. According to the results, androgen excess was associated with IR in young females and TT appeared to be independent predictor of IR in these patients. These data may suggest that simultaneous quantification of an androgen profile including at least TT, DHT, and 17OHP can present useful clinical information for assessment of androgen excess.

Abstract
OBJECTIVE To summarize current evidence regarding testosterone treatment for women with low sexual desire. MATERIALS AND METHODS The Female Endocrinology and Andrology Department of the Brazilian Society of Endocrinology and Metabolism invited nine experts to review the physiology of testosterone secretion and the use, misuse, and side effects of exogenous testosterone therapy in women, based on the available literature and guidelines and statements from international societies. RESULTS Low sexual desire is a common complaint in clinical practice, especially in postmenopausal women, and may negatively interfere with quality of life. Testosterone seems to exert a positive effect on sexual desire in women with sexual dysfunction, despite a small magnitude of effect, a lack of long-term safety data, and insufficient evidence to make a broad recommendation for testosterone therapy. Furthermore, there are currently no testosterone formulations approved for women by the relevant regulatory agencies in the United States, Brazil, and most other countries, and testosterone formulations approved for men are not recommended for use by women. CONCLUSION Therefore, testosterone therapy might be considered if other strategies fail, but the risks and benefits must be discussed with the patient before prescription.

Abstract
Cardiovascular disease (CVD) is the number one cause of death in both men and women. Younger women have a lower risk for CVD, but their risk increases considerably after menopause when estrogen levels decrease. The cardiovascular protective properties of estrogen are mediated through decreasing vascular inflammation and progression of atherosclerosis, decreasing endothelial cell damage by preventing apoptosis and anti-hypertrophic mechanisms. Estrogen also regulates glucose and lipid levels, which are 2 important risk factors for CVD. Resveratrol (RES), a cardioprotective polyphenolic compound, is classified as a phytoestrogen due its capacity to bind to and modulate estrogen receptor signalling. Due to its estrogen-like property, we speculate that the cardioprotective effects of RES treatment could be sex-dependent. Based on earlier reports and more recent data from our lab presented here, we found that RES treatment may have more favourable cardiovascular outcomes in females than in males. This review will discuss estrogen- and phytoestrogen-mediated cardioprotection, with a specific focus on sex-dependent effects reported in preclinical and clinical studies.

Abstract
Adequate muscular strength is required to perform daily activitiesand is considered a marker of overall health. The aim of this study was to identify sociodemographic and lifestyle factors associated with handgrip strength (HGS) in adults and the younger segment of the older population. A cross-sectional,population-based study was conducted with 705 individuals aged between 25 and 65 years in the city of Florianópolis, capital of the State of Santa Catarina, Brazil.HGS was assessed usinga manual hand dynamometer. Interviews were conducted with the participants to collect sociodemographic and lifestyle data.Multiple linear regressionwas performed to identify the predictors of HGS. The findings revealed that women and individuals from older age groups showed lower HGS, while being active during leisure time was associated with higher HGS.Interventions aimed at maintaining HGS levels in individuals should pay special consideration toaging and individuals who are physically inactive or insufficiently active during leisure time.

Abstract
BACKGROUND & AIMS Testosterone plays a role in predisposing individuals to cardiovascular and metabolic diseases, but its effects differ between men and women. We investigated the association between serum total testosterone and non-alcoholic fatty liver disease in adults in the US. METHODS A cross-sectional analysis of data from participants in the 2011-2012 National Health and Nutrition Examination Survey was performed. Subjects with significant alcohol consumption and those with viral hepatitis were excluded. We used the highest sex-specific quartiles of serum total testosterone as references. Suspected non-alcoholic fatty liver disease was diagnosed when serum alanine aminotransferase was >30 IU/L for men and >19 IU/L for women. RESULTS Of the 4758 subjects (49.4% men), the prevalence of suspected non-alcoholic fatty liver disease was inversely correlated with the sex-specific quartiles of testosterone in men and women. In a multivariate model, low total testosterone levels were associated with progressively higher odds of suspected non-alcoholic fatty liver disease in men after adjusting for age, obesity and other metabolic risk factors (P values for trends <.01). When the women were divided into 2 groups according to menopausal status, a significant correlation was observed only in the post-menopausal women (P values for trends <.01). The adjusted odds ratios for suspected non-alcoholic fatty liver disease were 1.72-1.99 in men and 2.15-2.26 in post-menopausal women (lowest quartile vs highest quartile). CONCLUSIONS In this nationally representative sample of adults in the US, low total testosterone levels were associated with suspected non-alcoholic fatty liver disease in men and post-menopausal women independent of known risk factors.

The aim of this study was to determine whether a single bout of aerobic exercise would increase the androgen hormone concentration in mouse BAT and whether its increase was associated with uncoupling protein-1 (UCP-1), protein kinase A (PKA)-related mechanism in BAT. [Methods] Twenty, 9-week-old ICR adult male micewere randomly divided into three groups: Control (n=6, CON), Exercise (n=7, EX), and Exercise + SRD5A1A2 inhibitor (n=7, EXIN). SRD5A1A2 is an enzyme needed when free testosterone is metabolized to dihydrotestosterone (DHT). SRD5A1A2 was administered intraperitoneally in the EXIN group, while the CON and EX groups were treated with the vehicle only. One hour later, exercise was performed at 60–70% V˙O2max for 30minutes. The levels of testosterone and DHT in BAT were determined by ELISA, and UCP-1 mRNA level was examined by RT-PCR. UCP-1 and PKA protein levels were determined by western blotting. [Results] After a single period of exercise, testosterone and DHT concentrations in BAT were significantly higher in EX than those in CON, and lower in EXIN than those in EX. The ratio of phosphorylated PKA to total PKA in BAT was significantly higher in EX than that in CON, and lower in EXIN than that in EX. UCP-1 levels in BAT were not different in the three groups. [Conclusion] Aerobic exercise increased bioactive androgen hormone levels in BAT in association with the increase in phosphorylated PKA levels. In contrast, 30minutes of treadmill exercise did not affect UCP-1 expression.

Abstract
BACKGROUND Systemic sclerosis (SSc) is a multisystem disease affecting the skin, respiratory system and skeletal muscles. In SSc patients, hand function disability is the major factor limiting daily activities. AIM To evaluate the association of physical function with handgrip strength and pulmonary function in SSc patients. A further aim was to assess the relationship between handgrip strength and pulmonary function in patients with SSc. METHOD A cross-sectional study in which 28 patients with SSc underwent isometric handgrip strength (IHGS) measurement and pulmonary function tests and completed the Health Assessment Questionnaire Disability Index (HAQ-DI) to measure physical function. RESULTS The HAQ-DI scores were associated with the IHGS (rs = -0.599, P = 0.001) and pulmonary function parameters, particularly the diffusion capacity for carbon monoxide (DLco; rs = -0.642, P = 0.0004). CONCLUSION In patients with SSc, the degree of physical disability is associated with both hand grip strength and pulmonary function. However, there is no relationship between handgrip strength and pulmonary function in these patients.

Abstract
Testosterone is an androgenic steroid hormone, which plays an important role in the regulation of male reproduction and behaviors, as well as in the maintenance of insulin sensitivity. Several studies showed that testosterone exerted beneficial effects in brain function, including preventing neuronal cell death, balancing brain oxidative stress and antioxidant activity, improving synaptic plasticity and involving cognitive formation. Although previous studies showed that testosterone deficiency is positively correlated with cognitive impairment and insulin-resistant obesity, several studies demonstrated contradictory findings. Thus, this review comprehensively summarizes the current evidence from in vitro, in vivo and clinical studies of the relationship between testosterone deficiency and insulin-resistant obesity as well as the correlation between either insulin-resistant obesity or testosterone deficiency and cognitive impairment. Controversial reports and the mechanistic insights regarding the roles of testosterone in insulin-resistant obesity and cognitive function are also presented and discussed.

Abstract
Androgens are known to play a pivotal role in cardiovascular function. However, a definitive explanation as to how their impact differs between genders is yet to be provided. In this review, the existing studies on the link between androgens and cardiovascular disease have been analysed, with a particular focus on the gender-specific differences. Several studies agree that both direct and indirect effects of testosterone on cardiovascular function show a gender-related dimorphism. Consistently, men and women display different responses to androgen supplementation treatment. Post-menopausal women may particularly benefit from testosterone supplementation therapy. Future studies should further clarify the optimal dose and route of administration of testosterone, and more women should be included in clinical trials, in order to identify novel gender-specific targets, and finally to develop therapeutic strategies.

Abstract
It is well documented in the current literature that chronic heart failure is often associated with cachexia, defined as involuntary weight loss of 5 % in 12 month or less. Clinical studies unraveled that the presence of cachexia decreases significantly mean survival of the patient. At the molecular level mainly myofibrillar proteins are degraded, although a reduced protein synthesis may also contribute to the loss of muscle mass. Endocrine factors clearly regulate muscle mass and function by influencing the normally precisely controlled balance between protein breakdown and protein synthesis The aim of the present article is to review the knowledge in the field with respect to the role of endocrine factors for the regulation of cachexia in patients with CHF and deduce treatment perspectives.

Abstract
The handgrip strength is considered an excellent predictor of morbidity and mortality for acute and long term outcomes. In fact, several studies showed that the reduced handgrip strength is correlated to all-cause mortality in both middle aged and elderly subjects. Nevertheless, defined reference values of handgrip strength are not available, especially from young and healthy populations. The aim of this study was to determine the reference values for handgrip strength from a healthy population of young volunteers. A secondary objective was to derivate a muscle function T score useful for adults and elderly individuals. We enrolled 335 healthy university students (157 men and 178 females) aged 19-25 years. The handgrip strength was measured using a hydraulic hand dynamometer by trained dietitians. The mean handgrip strength value was 27.70 ± 4.3 kg for female and 44.77 ± 6.6 kg for male. We showed statistical difference between sexes. We also found the lower T score in community-dwelling elderly individuals in comparison to the young people. The muscle strength loss is a multi-factorial process influenced by age and hormonal factors. The availability of the reference values in both sexes might open the way to the diffusion of the handgrip strength assessment for more clinical use, and it might be useful to identify people who could benefit from early nutritional or pharmacological programs.

Abstract
We determined the effect of chronic androgen suppression on inflammation in women with polycystic ovary syndrome (PCOS) compared to weight-matched controls. We performed a pilot project using samples from previous prospective, controlled studies. Nine women with PCOS (5 obese, 4 lean) and 9 ovulatory controls (5 obese, 4 lean) participated in the study. Androgens, C-reactive protein (CRP), interleukin-6 (IL-6), free fatty acids (FFA) and body weight were measured before and after 3 and 6 months of gonadotropin-releasing hormone (GnRH) agonist administration. GnRH agonist treatment decreased estradiol, testosterone and androstenedione to similar levels in all subjects. CRP and IL-6 increased in obese women with PCOS, was unaltered in lean women with PCOS and obese controls, and decreased in lean controls after 6 months of treatment. FFA decreased and body weight increased in obese women with PCOS, but did not change significantly in lean women with PCOS and in either control group after 6 months of treatment. The testosterone reduction was related to increases in weight and IL-6. The fall in FFA was related to the rise in CRP. The increases in weight and IL-6 were related to the rise in CRP. We propose that hyperandrogenism in PCOS may exert an anti-inflammatory effect when obesity is present, but may not promote inflammation in the disorder; and that circulating androgens have a pleiotropic effect on inflammation depending on the combination of PCOS and weight status in a given individual.

Abstract
Testosterone deficiency is a generalized phenomenon seen in the course of chronic heart failure (CHF). Reduction in circulating testosterone level is a predictor of deterioration of functional capacity over time, underscoring the role of testosterone deficiency in CHF. Anabolic hormones are determinants of exercise capacity and circulating levels of anabolic hormones strongly determine muscle mass and strength. Testosterone deficiency is involved in the pathophysiology of CHF, contributing to some features of this syndrome, such as the reduced muscle mass, abnormal energy handling, fatigue, dyspnea and, finally, cachexia. This review summarizes current knowledge on the role of testosterone deficiency in the pathophysiology of CHF, gaining insights from the potential implications of testosterone as supplementation therapy.
