Background: Animal models and observational studies have suggested a favorable role of vitamin D in male reproduction. However, randomized clinical trials investigating the effect of vitamin D supplementation on male fertility are limited. Therefore, this study aimed to examine the effect of vitamin D supplementation on semen quality, reproductive hormones, and anthropometric measurements in vi...

Body fat (BF) and cardiorespiratory fitness (CRF) are important health markers that ought to be considered in screening exams. The aim of this study was assess the value six indicators, i.e., tri-ponderal mass index (TMI), relative (RFM), waist–BMI ratio, waist-to-height ratio (WHtR), waist-to-hip (WHR) body (BMI) predicting CRF school-aged children. analysis based on data coming from examinati...

PURPOSE Obesity is associated with cardiovascular disease, affecting large arteries and the microcirculation. Waist circumference and body mass index are routinely employed as measures for assessing obesity-related health risk, whereas waist-to-hip ratio is not. We aimed to investigate the association between brachial vascular reactivity and body mass index, waist circumference, and waist-to-hi...

Background: Metabolic syndrome (MS) is a cluster of metabolic disturbances, and its prevalence is increasing worldwide. MS exhibits variations among ethnic groups. Zoroastrianism is an ethnic minority which has maintained its isolation and endogamy up to now. So, we evaluated the frequency of MS in Zoroastrians of Yazd, Iran.   Methods: In this cross-sectional study, participants aged &...

BACKGROUND Subclinical hypothyroidism (SH) is associated with cardiovascular metabolic syndromes, especially dislipidemia and abdominal obesity. Visceral abdominal adipose tissue (VAAT) and epicardial adipose tissue (EAT) have the same ontogenic origin and produce many proinflammatory and proatherogenic cytokines. We evaluated EAT and VAAT thickness in patients with SH. METHODS Forty-one pati...

OBJECTIVE: To evaluate the accuracy and usefulness of predicting birth weight by measuring fetal thigh circumference by ultrasound. METHODS: In 110 pregnant women, fetuses without structural or chromosomal anomalies were studied prospectively and cross-sectionally. Thigh circumference (TC) was determined at the mid level of the thigh. Biparietal diameter (BPD), Head circumference (HC), Abdomina...

Background: Given that abdominal obesity increases the risk of affecting metabolic and cardiovascular diseases, this study was conducted to determine the relationship between energy and macronutrient intake with women's abdominal obesity in Sabzevar. Methods: In this study, 225 female nurses and medical staff in Vase’e hospital of Sabzevar were selected. In order to assess the dietary int...

This paper compares body mass index, waist circumference, hip circumference, and waist-hip ratio as risk factors for ischaemic heart disease and stroke in Asia Pacific populations. We undertook a pooled analysis involving six cohort studies (45 988 participants) and used Cox proportional hazards regression to assess the associations of the four anthropometric indices with stroke and ischaemic h...
