Published: June 2015

Background: Waist circumference (WC) to height ratio (WC/HT) is used as a measure of central obesity. However, the optimum ratio that will separate populations with high from low cardiovascular risk remains controversial. This investigation evaluates an optimum WC/HT value to define central obesity in children.

Methods: The sensitivity and specificity of WC/HT in 649 children (age 2-18 years) without evidence of heart disease were analyzed for WC and for body mass index (BMI).

Results: A WC/HT ≥0.5 resulted in sensitivity:specificity of 99%:72% for detecting central obesity and 83%:77% for detecting overweight (BMI ≥85th percentile) subjects. A value of WC/HT ≥0.55 yielded sensitivity:specificity of 80%:96% for detecting central obesity and 75%:94% for detecting subjects with obesity (BMI ≥95th percentile).

Conclusions: The use of WC/HT between ≥0.5 and <0.55 identified subjects at-risk for central obesity and WC/HT ≥0.55 identified central obesity with a high probability.

Obesity and its associated metabolic disorders are significant global health challenges, necessitating novel therapeutic approaches. This study explores the anti-adipogenic and anti-dyslipidemic properties of 4655-EF, a novel phytopharmaceutical derived from Polyalthia longifolia, and explores the molecular pathways involved in its pharmacological activity. This phytopharmaceutical was prepared using a bioactivity-guided supercritical fluid extraction method suitable for large-scale production.

Plastic materials are ubiquitous, leading to constant human exposure to plastic additives such as plasticizers. There is growing evidence that plasticizers may contribute to obesity due to their disruptive effects on metabolism. Alternatives like diisononylcyclohexane-1,2-dicarboxylate (DINCH) are replacing traditional phthalates such as di-(2-ethylhexyl) phthalate (DEHP), which are now banned due to their proven harmful health effects.

Background: Precision nutrition-based methods develop tailored interventions and/or recommendations accounting for determinants of intra- and inter-individual variation in response to the same diet, compared to current 'one-size-fits-all' population-level approaches. Determinants may include genetics, current dietary habits and eating patterns, circadian rhythms, health status, gut microbiome, socioeconomic and psychosocial characteristics, and physical activity. ​​​​In this systematic review, we examined the evidence base for the effect of interventions based on precision nutrition approaches on overweight and obesity in children and adolescents to help inform future research and global guidelines.
