“…Previous works have indicated that obesity may contribute to chronic inflammation and oxidative stress, which can lead to prostate tissue remodeling and enlargement 38 . Given that WC increases with age, 39 it is difficult to identify the causal effect of WC on BPH in cross‐sectional studies. Wang et al undertook a two‐sample MR analysis of the effect of lifestyle on BPH and concluded that elevated WC increased the genetic liability for BPH, even after adjusting for BMI 22 .…”

BackgroundPrevious observational studies have indicated that metabolic abnormalities are associated with benign prostatic hyperplasia (BPH). The limitations of the research methodology of observational studies do not allow causal inference to be drawn; however, Mendelian randomization (MR) can clarify this.MethodsUsing summary‐level data from genome‐wide association studies, we conducted a two‐sample MR study to examine the causality of the metabolic syndrome (MetS) and its components on BPH (26,358 BPH cases and 110,070 controls). The random‐effects inverse‐variance weighted was employed as the primary method for MR analyses.ResultsWe observed that genetically predicted waist circumference (WC) (odds ratio [OR] = 1.236, 95% confidence interval [CI]: 1.034−1.478, p = 0.020) and diastolic blood pressure (DBP) (OR = 1.011, 95% CI: 1.002−1.020, p = 0.020) were significantly positively associated with BPH risk. We did not identify a causal effect of MetS (OR = 0.975, 95% CI: 0.922−1.031, p = 0.375), systolic blood pressure (OR = 1.004, 95% CI: 0.999−1.008, p = 0.115), triglycerides (OR = 1.016, 95% CI: 0.932−1.109, p = 0.712), high‐density lipoprotein (OR = 1.005, 95% CI: 0.930−1.086, p = 0.907), and fasting blood glucose (OR = 1.037, 95% CI: 0.874−1.322, p = 0.678) on BPH. In the multivariable MR analysis, we observed that the risk effect of DBP (OR = 1.013, 95% CI: 1.000−1.026, p = 0.047) on BPH persisted after conditioning with WC (OR = 1.132, 95% CI: 0.946−1.356, p = 0.177).ConclusionsOur study provides genetic evidence supporting the causal effect of DBP on BPH, although the effect of WC needs to be further validated.

“…There was no pubertal stage or maturation differentiation between the groups of children and adolescents The groups categorization by age were founded in evidence of different existing percentiles of anthropometric measurements by sex and age, as well as cut-off points to assess central obesity in children, adolescents, and adults. In fact, BMI and waist circumference show differences by age [27,28], tending to increase its values with age [29] and suggesting that mortality risk is also age related [30].…”

The accumulation of body fat is an important cardiometabolic risk factor; however, there is no consensus about which measure is more reliable for the assessment of cardiometabolic risk in people with intellectual disabilities. The aim of the present study was to primarily validate the submandibular skinfold as an anthropometric measurement of cardiometabolic risk in children, adolescents, and adults with intellectual disabilities, using a cross-sectional study made up of 131 people (67.2% men) with mild and moderate intellectual disability. The cardiometabolic risk indicators used were: body mass index (kg/m2), neck circumference (cm), waist circumference (cm), calf circumference (cm) and waist-to-height ratio. Moderate correlations were demonstrated between the submandibular skinfold measure and the anthropometric measurements analyzed in the three age categories, showing the highest correlation (r = 0.70) between the submandibular skinfold and BMI in the adolescent group and waist-to-height ratio in adults. The implementation of the submandibular skinfold measurement is suggested as an easy, fast, and minimally invasive anthropometric measurement as part of the physical and nutritional evaluation for the assessment of cardiometabolic risk in people with intellectual disabilities.

“…There is some controversy over the indication of using NC and its predictive role for body composition [ 21 , 22 ]. NC is simple, cheap, fast to measure, highly reproducible, and less-varied in age compared to WC [ 23 , 24 ]. It is more feasible in overcrowded clinics and more culturally accepted.…”

Background and Aims. Upper body fat distribution is more related to cardiometabolic diseases than central obesity. Neck circumference (NC) and neck-to-height ratio (NHtR) are two indicators of upper body obesity that are affordable, easy to obtain, highly reproducible, and more practical in the crowded health centers than the classic anthropometric indices. Methods. 18–65-year-old individuals with no past medical history were included. After obtaining written informed consent, they were screened for hypertension, high blood glucose, and other abnormal laboratory results. Data were analyzed using SPSS and Mann–Whitney U test, Chi square test, Spearman’s correlation coefficient, and ROC curve. Results. In our 2,812 participants, NC had the lowest area under the curve (AUC) in both male and female obese and overweight subjects. NHtR and hip circumference (HC) had the highest AUC in men and women with obesity, respectively. The highest sensitivity for overweight men and women belonged to waist circumference (WC) and waist-to-height ratio (WHtR), respectively, and for both males and females with obesity, NHtR had the highest sensitivity. The cutoff point of NHtR had the same value for males and females. HC and NHtR had the highest positive likelihood ratio (PLR) for obesity in men. In addition, HC and WC had the highest PLR for obesity in women. Conclusion. In this study, we revealed that NC had the lowest and NHtR and HC had the highest predictive value for obesity. Furthermore, for both males and females with obesity, NHtR had the highest sensitivity. HC had the highest PLR for obesity in both genders. Our results warrant prospective studies to evaluate the role of NHtR and other novel anthropometric indices in the risk of cardiometabolic diseases.
