Insights

This study constructed body mass index (BMI) percentiles for infants and young children, finding slight increases compared to World Health Organization (WHO) standards. These findings aid in monitoring child growth and nutritional status.

Area of Science:

  • Pediatrics
  • Anthropometry
  • Public Health

Background:

  • Monitoring infant and child development is crucial for assessing health and nutritional needs.
  • Anthropometric parameters are routinely measured to track growth patterns post-birth.

Purpose of the Study:

  • To construct current body mass index (BMI) percentiles for children aged 0-24 months.
  • To compare these constructed BMI percentiles with existing literature and World Health Organization (WHO) data.

Main Methods:

  • A cross-sectional study involving 1,345 boys and 1,364 girls aged 0-24 months.
  • Body mass index (BMI) data collected from January 2018 to December 2021.
  • BMI growth curves generated using the LMS method and RefCurv software, with the 'gamlss' package for parameter selection.

Main Results:

  • Smoothed BMI growth curves constructed for both genders (3rd-97th percentiles).
  • Model adequacy confirmed via worm plots, indicating a sufficient fit.
  • 95% of BMI values fell within two elliptic curves, demonstrating model reliability.

Conclusions:

  • The study established gender-specific BMI percentile curves for infants and young children.
  • A slight increase in BMI percentile values was observed compared to WHO standards.

Bacterial Growth Curve01:28

Bacterial Growth Curve

The bacterial growth curve is a fundamental concept in microbiology that describes the dynamics of bacterial population growth in a closed system with controlled environmental conditions, such as temperature and nutrient availability. This curve is divided into four distinct phases: lag, log (exponential), stationary, and death phases, each reflecting a unique stage of bacterial adaptation and growth. During the lag phase, bacteria acclimate to their surroundings by synthesizing essential...

Growth of Cartilage and Bone Tissue01:27

Growth of Cartilage and Bone Tissue

Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...

z Scores and Area Under the Curve

z scores are the standardized values obtained after converting a normal distribution into a standard normal distribution. A z score is measured in units of the standard deviation. The z score tells you how many standard deviations the value x is above (to the right of) or below (to the left of) the mean, μ. Values of x that are larger than the mean have positive z scores, and values of x that are smaller than the mean have negative z scores. If x equals the mean, then x has a z score of...

Changes in the Appendicular Skeleton with Age

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Signs of Puberty01:27

Signs of Puberty

Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

Oxygen Requirements and Growth Patterns01:29

Oxygen Requirements and Growth Patterns

Microorganisms exhibit diverse oxygen requirements and growth patterns driven by their metabolic strategies and environmental adaptations. Oxygen, while essential for many organisms, can also be toxic under certain conditions, shaping how microorganisms grow and survive.Oxygen Requirements of MicroorganismsMicroorganisms are classified based on their ability to use or tolerate oxygen:● Obligate aerobes like Mycobacterium tuberculosis need oxygen for energy production, as it serves as the...
