Insights

Pediatric obesity prevalence in Korea has significantly increased, rising from 8.7% in 2007 to 15.0% in 2017. This trend highlights the urgent need for updated epidemiologic data and effective obesity control strategies.

Area of Science:

  • Public Health
  • Epidemiology
  • Pediatrics

Background:

  • Pediatric obesity rates are rising globally and in Korea.
  • Childhood obesity is linked to health issues in both childhood and adulthood.

Purpose of the Study:

  • To review and analyze the prevalence of pediatric obesity in Korea.
  • To compare obesity prevalence using different data sources and growth charts.

Main Methods:

  • Utilized data from the National School Health Examination (NSHE) and Korea National Health and Nutrition Examination Survey (KNHANES).
  • Defined obesity using Body Mass Index (BMI) thresholds and age/sex-specific percentiles based on 2007 and 2017 growth charts.

Main Results:

  • Obesity prevalence increased from 8.7% (2007) to 15.0% (2017) in NSHE data (ages 6-18).
  • Obesity prevalence increased from 8.6% (2001) to 9.8% (2017) in KNHANES data (ages 2-18).
  • Higher increases observed in boys and high school students.

Conclusions:

  • Accurate, updated epidemiologic data using 2017 growth charts are crucial for developing obesity control strategies.
  • Further collection of reliable, nationally representative data, including longitudinal studies, is recommended.

Pharmacokinetics in Pediatric Patients: Drug Distribution

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight,...

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...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses...

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Drug Dosing: Obese Patients

In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

Obesity01:24

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...
