Excessive weight gain in exclusively breast-fed infants
Summary
Exclusive breastfeeding is linked to lower childhood obesity, but this study identified exclusively breastfed infants with excessive weight gain. Variations in maternal breast milk composition may influence infant growth patterns.
Area of Science:
- Pediatrics
- Human Nutrition
- Infant Health
Background:
- Exclusive breastfeeding is recommended for infant nutrition.
- Observational studies link it to reduced childhood obesity.
- This study investigates exclusively breastfed infants with excessive weight gain.
Purpose of the Study:
- To describe characteristics of exclusively breastfed obese infants.
- To identify factors contributing to unusual infant weight gain.
- To explore maternal, infant, and feeding pattern influences.
Main Methods:
- Descriptive, prospective cross-sectional study.
- Followed exclusively breastfed infants with excessive weight gain (2003-2015).
- Analyzed maternal, infant, feeding patterns, and breast milk macronutrients.
Main Results:
- 73 infants studied; 63% were girls.
- 100% had weight-for-height SDS >2 by 12 months.
- Lower fat content found in analyzed breast milk samples.
Conclusions:
- Inter-individual variations in maternal milk composition may impact infant growth.
- Further research is needed to understand these variations.
- This challenges assumptions about exclusive breastfeeding and obesity risk.

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

Drug metabolism, a critical process in the liver, involves two primary phases: Phase I reactions and Phase II conjugation. Obesity introduces significant alterations in this metabolic process, primarily due to fatty infiltration of the liver, leading to conditions such as nonalcoholic fatty liver disease (NAFLD). This condition can modify the activities of both Phase I and II enzymes, impacting how drugs are metabolized in obese patients.Phase I metabolism sees variable effects across...

Obesity significantly alters the pharmacokinetic processes of drug absorption and distribution, presenting unique challenges in medical treatment. The increased fat tissue and decreased lean muscle in obese individuals can significantly affect how drugs are absorbed into the body and distributed across different tissues. This alteration can lead to variances in the effectiveness and safety of medications, necessitating adjustments in dosing or drug selection for obese patients.One notable...

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...
