Nonalcoholic steatohepatitis, a progressive form of nonalcoholic fatty liver disease (NAFLD), is one of the most common hepatic diseases in children who present with particular risk factors including obesity, sedentary lifestyle, and/or a predisposing genetic background. The worldwide prevalence of NAFLD in children is a worrying phenomenon because this disease is closely associated with the development of both cirrhosis and cardiometabolic syndrome in adulthood. To date, the etiopathogenesis of primary NAFLD in children is unknown...

BACKGROUND: Aberrant crypt foci (ACF) are commonly considered the early pre-cancerous lesions that can progress to colorectal cancer (CRC). The available literature data reveal that age, dietary factors and lifestyle can affect the development of several dozen percentages of malignant tumours, including CRC. In the present study, an attempt was made to assess the incidence and growth dynamics of ACF and to determine whether the type of diet affected the development and number of AFC. METHODS: Colonoscopy combined with rectal mucosa staining with 0...

A PC Program for X ray Monte Carlo (PCXMC) has been used to calculate organ doses in patient dosimetry and for the exposure assessment in epidemiological studies of ra- diogenic health related risks. This study compared the dosimetry from using the built-in stylized phantoms in the PCXMC to that of a newer hybrid phantom library with improved anatomical realism. We simulated chest and abdominal x ray projections for 146 unique body size computational phantoms, 77 males and 69 females, with different combinations of height (125 - 180 cm) and weight (20 - 140 kg) using the built-in stylized phantoms in the PCXMC version 2...

CVD is the leading cause of death worldwide. Diet is a key modifiable component in the development of CVD. No official UK diet quality index exists for use in UK nutritional epidemiological studies. The aims of this study are to: (i) develop a diet quality index based on components of UK dietary reference values (DRV) and (ii) determine the association between the index, the existing UK nutrient profile (NP) model and a comprehensive range of cardiometabolic risk markers among a British adult population. A cross-sectional analysis was conducted using data from the Airwave Health Monitoring Study (n 5848)...

AIMS: Obesity is an established risk factor for type 2 diabetes mellitus (T2DM). However, there is limited information on the pattern of relationship between the risk for T2DM and body mass index (BMI) categories including underweight and overweight. Thus, this study was to evaluate the risk of T2DM according to BMI categories defined by Asian-specific cutoff of BMI. METHODS: 7660 non-diabetic Koreans were grouped into five BMI categories (underweight, normal, overweight, obese and severe obese) defined by Asian-specific cutoff of BMI and followed up for 10 years to monitor the development of T2DM...

Background: A significant number of cardiovascular disease (CVD)-related deaths occur in developing countries. An increasing prevalence of CVD is associated with a change in the macro-economy of these countries. In this post hoc analysis, CVD risk factor (CVDRF) prevalence is evaluated across countries based on national income in the Africa and Middle East Region (AfME). Methods: Data from the Africa Middle East Cardiovascular Epidemiological (ACE) study were used; a cross-sectional study in 14 AfME countries (94 clinics) from July 2011-April 2012, which evaluated CVDRF prevalence in stable adult outpatients...

BACKGROUND: Obesity and metabolic abnormalities are important risk factors for knee osteoarthritis (KOA). Recent epidemiologic studies have found that a high glycemic index (GI) and glycemic load (GL) diet are associated with a higher risk for metabolic complications and cardiovascular mortality. OBJECTIVE: We aimed to examine the association between dietary GI, dietary GL, and KOA among Korean adults. DESIGN: This was a cross-sectional study that analyzed data obtained from the Korean National Health and Nutrition Examination Survey 2010-2012...

Type 2 diabetes (T2D) is a chronic disease with a growing prevalence and a leading cause of death in many countries. Several epidemiological studies observed an association between T2D and increased risk of many types of cancer, such as gynecologic neoplasms (endometrial, cervical, ovarian and vulvar cancer). Insulin resistance, chronic inflammation and high free ovarian steroid hormones are considered the possible mechanisms behind this complex relationship. A higher risk of endometrial cancer was observed in T2D, even though this association largely attenuated after adjusting for obesity...

Obesity, particularly central adiposity, is a well-established risk factor for cardiovascular disease (CVD). Waist circumference (WC) is measured in numerous epidemiologic studies as a relatively simple indicator of central adiposity. However, recently, investigators have considered a measure that takes height into consideration, waist-to-height ratio (WHtR) as a more sensitive predictor of CVD. A limited number of studies have examined the association between various measures of central adiposity and obesity with CVD, but there is a dearth of information on this topic focused specifically on African American adults...

Y Luo, W C Blackledge
Worldwide, the growing obesity pandemic contributes to a range of chronic diseases. Recent epidemiological studies have suggested an association between obesity and the development of rheumatoid arthritis (RA), particularly among young women, whereby pro-inflammatory effects of adipokines provide one explanatory hypothesis. Yet, recent clinical and laboratory-based studies provide emerging evidence indicating microbiome involvement in RA initiation and development, including anti-citrullinated antibody formation and Th17 cell activation...

BACKGROUND: Epidemiology studies have revealed that patients with obesity, hyperglycemia, or hypertension are associated with a decreased urine pH. These metabolic disorders are related to insulin resistance; however, the association between urine pH and insulin resistance remains unclear. METHODS: To evaluate this association while controlling for covariates, the present study was conducted in 1084 non-diabetic Japanese subjects undergoing health examination. Fasting urine pH was analyzed using an automated urine dipstick analyzer...

Excess body weight and fat mass levels in children have previously been associated with childhood hypertension. The aim of the current study was to identify anthropometric and body composition indices most strongly associated with hypertension and to propose relevant cut-off values for these indices, above which the likelihood of hypertension in schoolchildren aged 9-13 years old is increased. A sample of 2,665 children participated in a cross-sectional epidemiological study, the Healthy Growth Study. The current study enrolled 1,315 children with full data on blood pressure, anthropometric, and body composition indices...
