Insights

The optimal timing for starting complementary feeding in preterm infants remains unclear. Current research shows no significant impact on body mass index (BMI) Z-scores, but more studies are needed to understand long-term effects on overweight risk.

Area of Science:

  • Pediatrics
  • Neonatology
  • Nutrition Science

Background:

  • The appropriate timing for initiating complementary feeding in preterm infants is a subject of ongoing debate.
  • Existing research suggests a potential link between complementary feeding timing and overweight development in term infants.

Purpose of the Study:

  • To systematically review the effect of complementary feeding initiation timing on overweight outcomes in preterm infants.

Main Methods:

  • A systematic literature search was conducted using terms related to preterm infants, complementary feeding, and overweight.
  • Five studies, including three randomized controlled trials and two cohort studies, were included in the review.

Main Results:

  • Two randomized controlled trials found no significant difference in body mass index (BMI) Z-scores at 12 months.
  • One randomized controlled trial indicated a greater growth rate in infants weaned earlier.
  • One observational study suggested delayed complementary feeding was associated with reduced length and weight Z-scores.

Conclusions:

  • No definitive conclusion could be drawn regarding the effect of complementary feeding timing on overweight in preterm infants.
  • Further research is necessary to clarify the impact of complementary feeding initiation timing on overweight in this population.

Initiation of Translation02:33

Initiation of Translation

Initiating translation is complex because it involves multiple molecules. Initiator tRNA, ribosomal subunits, and eukaryotic initiation factors (eIFs) are all required to assemble on the initiation codon of mRNA. This process consists of several steps that are mediated by different eIFs.
First, the initiator tRNA must be selected from the pool of elongator tRNAs by eukaryotic initiation factor 2 (eIF2). The initiator tRNA (Met-tRNAi) has conserved sequence elements including modified bases at...

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
Percentiles are a type of fractile that partition data into...

Review and Preview

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

Random and Systematic Errors01:20

Random and Systematic Errors

Scientists always try their best to record measurements with the utmost accuracy and precision. However, sometimes errors do occur. These errors can be random or systematic. Random errors are observed due to the inconsistency or fluctuation in the measurement process, or variations in the quantity itself that is being measured. Such errors fluctuate from being greater than or less than the true value in repeated measurements. Consider a scientist measuring the length of an earthworm using a...
