Insights

Childhood obesity is rising. This study found increased waist circumference (WC) and waist-to-height ratio (WHtR) in 6-12-year-olds compared to previous data, recommending these as key indicators.

Area of Science:

  • Pediatrics
  • Public Health
  • Anthropometry

Background:

  • Global rise in childhood overweight and obesity necessitates monitoring adiposity.
  • Waist circumference (WC) and waist-to-height ratio (WHtR) are key indicators of central obesity.

Purpose of the Study:

  • To assess current waist circumference (WC) and waist-to-height ratio (WHtR) measurements in children aged 6-12 years.
  • To compare these measurements with findings from earlier studies.

Main Methods:

  • Cross-sectional study of 2271 children (1150 boys) aged 6-12 years in 2015.
  • Measurements included height, weight, and waist circumference (WC).
  • Parental education level served as a proxy for socioeconomic status.

Main Results:

  • Significant age-related increase in WC for both sexes (p < .0001).
  • Higher WC observed in boys aged 10 and 12 years compared to girls.
  • Waist-to-height ratio (WHtR) decreased with age in girls (p < .0001); 14% had WHtR ≥ 0.50.
  • Current WC and WHtR are higher than in previous studies, despite similar weight and BMI.

Conclusions:

  • Waist circumference (WC) and waist-to-height ratio (WHtR) are recommended for identifying central obesity in children.
  • Findings indicate an increase in WC among 6-12-year-old children compared to historical data.

Fischer Projections02:18

Fischer Projections

Learning to draw Fischer projections of molecules and understanding their relevance plays a crucial role in the visual depiction of organic molecules. A Fischer projection is a two-dimensional projection on a planar surface to simplify the three-dimensional wedge–dash representation of molecules. This is especially helpful in the case of molecules with multiple chiral centers that can be difficult to draw. Here, all the bonds of interest are represented as horizontal or vertical lines. While...

Newman Projections02:06

Newman Projections

Different notations are used to represent the three-dimensional structure of molecules on two-dimensional surfaces. One of the most commonly used representations is the dash-wedge formula. The dashed wedges, solid wedges, and the plane lines indicate the groups situated behind the plane, coming out of the plane, and in the plane, respectively.
The organic molecules rotate across the single bonds leading to numerous temporary three-dimensional structures of varying energy known as...

Location and Orientation of the Heart01:13

Location and Orientation of the Heart

The human heart, despite its modest size and weight, is an organ of remarkable strength and endurance. Roughly the size of a fist, the heart weighs between 250 and 350 grams and is nestled within the mediastinum, the medial cavity of the thorax. It extends obliquely for about 12 to 14 cm, resting on the superior surface of the diaphragm. The heart is positioned anterior to the vertebral column and posterior to the sternum, with two-thirds of its mass lying to the left of the midsternal line.

Coordinates and Map Projections

Coordinates and map projections are essential tools in accurately representing the Earth's surface for various applications, ranging from navigation to spatial analysis. The latitude and longitude coordinate system is a universally recognized framework for defining locations. Latitude specifies the distance of a point north or south of the equator, measured in degrees from 0° at the equator to 90° at the poles. Longitude indicates a location's position east or west of the prime meridian,...

Health Literacy01:21

Health Literacy

Health literacy is an individual's or a community's capacity to comprehend, receive, read, and use relevant healthcare information and services. The World Health Organization (WHO, 2018) defines health literacy as the cognitive and social skills that determine the ability of individuals to gain access to, understand, and use information in ways that promote and maintain good health. As a result, the WHO helps individuals manage long-term health concerns, participate in preventative...

Methods of Documentation I: Source-Oriented Records

Source-oriented records, or SOR, are medical record-keeping organized by the data source. The SOR system was first developed in the mid-1900s to organize the growing patient data in hospitals and other healthcare facilities.
In an SOR, each discipline involved in patient care maintains a separate medical record section. This record-keeping method enables easy tracking of patient progress and ensures healthcare staff have access to up-to-date information.
