Insights

Most parents start infants on whey-based formula but switch to non whey-based formula before 12 months. Perceived infant hunger, not medical advice, drives this change in infant formula choice.

Area of Science:

  • Pediatrics
  • Infant Nutrition
  • Public Health

Background:

  • Standard whey-based infant formula is recommended for formula-fed infants.
  • Limited data exists on parental adherence to whey-based formula for the first year.
  • Parental motivations for infant formula selection are largely unknown.

Purpose of the Study:

  • To describe the use of whey-based and non whey-based infant formula by parents in the first year of life.
  • To identify reasons for parental formula switching.

Main Methods:

  • Utilized data from the Cork BASELINE Birth Cohort Study.
  • Examined infant feeding at 2, 6, and 12 months.
  • Employed descriptive analysis and logistic regression.

Main Results:

  • Whey-based formula use decreased significantly over the first year (62.4% at 2 months to 12.8% at 12 months).
  • No consistent parental or infant factors influenced whey-based formula use.
  • Perceived infant hunger was the primary reason for switching to non whey-based formula.

Conclusions:

  • Most infants start on whey-based formula but transition to non whey-based formula before 12 months.
  • Parental perception of satiety, not professional advice, is the main driver for formula changes.
  • Further research is needed on the growth effects of different infant formulas.

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...

Bioavailability Study Design: Healthy Subjects Versus Patients

Bioavailability studies are essential for evaluating a drug's therapeutic efficacy and understanding its absorption patterns under various physiological conditions. Conducting such studies on target patient populations provides more relevant data by simulating real-world disease states. However, practical challenges often necessitate the use of young, healthy adult volunteers as study subjects.Patients may exhibit altered drug absorption patterns due to the effects of the disease itself,...

Bioavailability Study Design: Single Versus Multiple Dose Studies

Bioavailability studies are essential for understanding how a drug is absorbed, distributed, metabolized, and excreted in the body. These studies assess the extent and rate at which the active pharmaceutical agent becomes available at the site of action. The design of bioavailability studies can involve single-dose or multiple-dose regimens, each with distinct advantages and limitations.Single-dose studies are the preferred approach due to their simplicity and reduced drug exposure for...

Bioavailability Study Design: Absolute Versus Relative Bioavailability

Bioavailability is a crucial pharmacokinetic parameter that quantifies the proportion of an administered drug that reaches the systemic circulation and is available for therapeutic action. Regulatory agencies mandate the assessment of bioavailability, typically measured as the area under the drug plasma concentration-versus-time curve (AUC), to ensure the efficacy and safety of pharmaceutical products. These evaluations are categorized as absolute and relative bioavailability studies.Absolute...

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...
