Insights

Iranian schoolchildren aged 7-11 years showed significant differences in body mass index (BMI) centiles compared to international references. Local BMI curves are needed for accurate assessment of child growth in Babol.

Area of Science:

  • Pediatric Endocrinology
  • Public Health Nutrition
  • Growth Monitoring

Background:

  • Child body mass index (BMI) is a key health indicator.
  • International BMI references exist, but their applicability to Iranian children is unconfirmed.

Purpose of the Study:

  • To establish BMI-for-age growth curves for Iranian schoolchildren aged 7-11 years in Babol.
  • To compare these local curves with World Health Organization (WHO 2006) and Centers for Disease Control and Prevention (CDC 2000) references.

Main Methods:

  • Stratified multistage cluster sampling included 4,083 schoolchildren (48.8% boys) from urban and rural Babol.
  • Height and weight were measured to calculate BMI.
  • Smoothed BMI-for-age curves were generated and compared with WHO and CDC references.

Main Results:

  • Significant differences were observed between Iranian and international BMI curves, particularly at upper centiles.
  • The 5th centile of the Iranian data closely aligned with the reference curves.
  • The study included a substantial sample size from diverse geographic settings within Babol.

Conclusions:

  • BMI centiles for Iranian schoolchildren (7-11 years) in Babol diverge from international standards.
  • Development of local, population-specific BMI curves is crucial for accurate physical growth assessment in this demographic.

Drug Dosing in Renal Diseases: Estimation of Glomerular Filtration Rate Based on Serum Creatinine Concentration

Glomerular filtration rate (GFR) can be estimated from serum creatinine using the modification of diet in renal disease (MDRD) formula or the chronic kidney disease–epidemiology collaboration (CKD–EPI) equation. Both methods are widely used in clinical practice to assess kidney function and guide treatment decisions.The MDRD equation does not require weight or height measurements and is normalized to the body surface area of 1.73 m², considered the average adult surface area.

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

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...

Population Growth00:57

Population Growth

Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

Socioemotional Experience and Gender Development

Social-emotional experiences and cultural influences play significant roles in shaping gender development. During middle childhood, from ages 6 to 11, peer groups become dominant in reinforcing gender norms. Children in this age group often align with same-gender peer groups, which actively encourage behaviors that conform to traditional gender roles. For instance, boys may be discouraged from engaging in activities perceived as feminine, reinforcing culturally dictated norms about masculinity...

Variation: Normal Distribution, Range, and Standard Deviation

In the field of psychology, there are several ways to organize measurements of a trait, feature, or characteristic (i.e., variables). Qualitative data, such as ethnicity, can be tabulated into a frequency count to provide information about the proportion, as well as the variety of groups in a sample or population. On the other hand, researchers can perform a wider set of calculations on quantitative data. The mean, mode, and median, for instance, are central tendency measures to identify a...
