Insights

Asian Indian children exhibit a "thin-fat" phenotype with higher body fat and insulin resistance compared to white UK children, despite lower BMIs. This metabolic profile persists even after adjusting for adiposity.

Area of Science:

  • Pediatric Endocrinology
  • Metabolic Health
  • Body Composition Analysis

Background:

  • The 'thin-fat' phenotype is recognized in Indian infants but poorly studied in older children.
  • Limited comparative data exists on the metabolic correlates of body composition in Indian versus white children.

Purpose of the Study:

  • To investigate the impact of body composition on metabolic profiles.
  • To compare Asian Indian and white UK children regarding body fat percentage and metabolic health.

Main Methods:

  • Measured Body Mass Index (BMI), waist circumference, skin-folds, and % body fat (dual-energy X-ray absorptiometry).
  • Assessed metabolic markers: glucose, insulin, insulin resistance (Homeostasis Model Assessment), lipids, and blood pressure.
  • Included 262 white UK children and 626 Indian children.

Main Results:

  • Indian children had lower BMI, waist circumference, and skin-folds but higher % body fat than white UK children.
  • Indian children exhibited higher fasting glucose, insulin, and insulin resistance (Homeostasis Model Assessment), independent of age and % body fat.
  • These differences were statistically significant (P < 0.001).

Conclusions:

  • The 'thin-fat' phenotype is present in pre-pubertal Indian children, characterized by higher adiposity despite lower BMI.
  • Indian children demonstrate increased insulin resistance compared to white UK children, even when accounting for body fat percentage.

Regression Toward the Mean01:52

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...
Nature and Nurture01:10

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience, such as differences...

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...

Bioavailability Study Design: Healthy Subjects Versus Patients

Bioavailability studies are essential for evaluating a drug's therapeutic efficacy and understanding its absorption patterns under various physiological conditions. Conducting such studies on target patient populations provides more relevant data by simulating real-world disease states. However, practical challenges often necessitate the use of young, healthy adult volunteers as study subjects.Patients may exhibit altered drug absorption patterns due to the effects of the disease itself,...

Bias in Epidemiological Studies

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:
