Objective: The present study examined the associations between adult food insecurity (FI) and percentage body fat (%BF) and BMI, stratified by height (HT).
Design, Setting And Subjects: %BF, HT and BMI of 2117 men and 1909 women in the National Health and Nutrition Examination Survey 1999-2002 were analysed in relation to adult food security status using multiple regression procedures.
Results: Compared with the fully food-secure, men's %BF, BMI and HT were lower as FI intensified. Marginal food security among women was associated with 1.3 cm shorter HT, P = 0.016. Marginal food security among women who were below median HT was associated with about 2.0 kg/m2 higher BMI, P = 0.042. %BF was not associated with FI among women.
Conclusions: FI is associated with shorter HT and lower %BF and BMI in men. Women's HT should be considered in the reported associations between FI and higher BMI.

Background: Epistasis, the phenomenon where the effect of one gene (or variant) is masked or modified by one or more other genes, significantly contributes to the phenotypic variance of complex traits. Traditionally, epistasis has been modeled using the Cartesian epistatic model, a multiplicative approach based on standard statistical regression. However, a recent study investigating epistasis in obesity-related traits has identified potential limitations of the Cartesian epistatic model, revealing that it likely only detects a fraction of the genetic interactions occurring in natural systems.

Background: Experimental and clinical studies have suggested that symbiotics might effectively manage type 2 diabetes mellitus (T2DM) by modulating the intestinal microbiota. However, these studies' limited sources, small sample sizes, and varied study designs have led to inconsistent outcomes regarding glycaemic control. This study aimed to investigate the effects of symbiotics on the anthropometric measures, glycaemic control, and lipid profiles of patients with T2DM.

Background: Exclusive breastfeeding (EBF) is defined as feeding infants only breast milk of the mother or a wet nurse for the first six months, without additional food or liquids except the oral rehydration solution or drops/syrups of vitamins, minerals or medicines. The working status of women in developed countries adversely affects the EBF rates, which calls for an assessment in rapidly developing countries like India. Therefore, the primary aim of the present study is to determine the prevalence of EBF using the data from the National Family Health Surveys (NFHS 3, 4, 5) conducted between 2005 and 06, 2015-16 and 2019-21 to estimate the likelihood EBF according to mothers' employment status.

Introduction: Obesity in older adults is linked to various chronic conditions and decreased quality of life. Traditional physical activity guidelines often overlook the specific postures and movements that older adults engage in daily. This study aims to explore the compositional associations between posture-specific behaviours and obesity risk in younger (M = 67.

Background: Endometriosis, a condition that significantly impacts the quality of life for affected women, manifests with a spectrum of symptoms ranging from mild discomfort to severe pelvic pain, dysmenorrhea, dyspareunia, and infertility. A previous single-center study suggested an elevated prevalence of endometriosis in Jordan, prompting the need for larger studies to confirm these findings.
Methods: We conducted a cross-sectional study involving a sample of 866 women who underwent various laparoscopic procedures for different indications at the Department of Obstetrics and Gynecology at Jordan University Hospital and Al-Karak Governmental Hospital, two tertiary referral hospitals in Jordan between January 2015 and March 2023.
