Insights

Exclusive breastfeeding for the first six months promotes higher vitamin A intake in infants aged 6-12 months. While iron intake was lower in breastfed infants, its bioavailability is higher, underscoring the benefits of breastfeeding.

Area of Science:

  • Pediatrics
  • Nutrition Science
  • Public Health

Background:

  • Infant nutrition is critical for child development.
  • Understanding the impact of breastfeeding on nutrient intake is essential for public health guidelines.
  • Vitamin A and iron are key micronutrients for infants.

Purpose of the Study:

  • To investigate the association between breastfeeding type (first six months) and vitamin A and iron intake (6-12 months).
  • To evaluate nutrient intake patterns in relation to different infant feeding practices.

Main Methods:

  • A cohort study involving 226 children.
  • Assessment of breastfeeding type (1-6 months) and food intake (6-12 months).
  • Statistical analysis using Kruskal-Wallis test and Poisson Regression.

Main Results:

  • 33.6% of children had inadequate vitamin A intake; 67.7% had inadequate iron intake.
  • Exclusive/predominant breastfeeding from birth to two months correlated with higher vitamin A intake (6-12 months).
  • Breastfeeding at six months was linked to higher vitamin A and lower iron intake (bivariate analysis).

Conclusions:

  • Exclusive breastfeeding in the first six months is crucial for adequate vitamin A intake.
  • While iron intake may appear lower in breastfed infants, breast milk's iron bioavailability is superior.
  • Promoting exclusive breastfeeding supports optimal micronutrient status in young children.

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

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...

Anatomy of the Intestines01:23

Anatomy of the Intestines

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Vitamins

Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced...

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...

Role of Skin in Vitamin D Synthesis01:23

Role of Skin in Vitamin D Synthesis

The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...
