Study Notes

Introduction

Nutrition is crucial for child health and influences long-term eating habits, metabolism, and weight.
Malnutrition, a significant public health issue, encompasses undernutrition (wasting, stunting, micronutrient deficiencies) and overnutrition (overweight, obesity).
It affects all age groups but children, the elderly, and those with chronic illnesses are especially vulnerable.
The Convention on the Rights of the Child emphasizes every infant's right to good nutrition.

Malnutrition Statistics

45% of child deaths are associated with undernutrition.
In 2022, 149 million children under 5 were stunted, 45 million wasted, and 37 million overweight or obese.
Only 1 in 5 children from the poorest households and rural areas receive the minimum diverse diet for healthy growth and development.
Many adolescents consume highly processed foods, with 42% drinking sugary drinks and 46% eating fast food regularly.
Malnutrition can threaten survival, growth, and development of children, impacting economies and nations.

Acute Malnutrition

It results from insufficient energy or protein intake.
Primary acute malnutrition is commonly seen in developing countries due to inadequate food supply.
Secondary acute malnutrition arises from underlying diseases causing nutrient loss, increased energy expenditure, or decreased food intake.
Primary acute malnutrition is often rooted in socioeconomic and environmental factors, including household food insecurity, poverty, and poor breastfeeding practices.
Environmental enteropathy, caused by exposure to pathogens, contributes to malnutrition through intestinal damage and malabsorption.

Pathophysiology of Acute Malnutrition

Inadequate energy intake leads to growth restriction, loss of muscle and fat, reduced basal metabolic rate, and decreased energy expenditure.
Biochemical changes affect thyroid hormones, insulin, and growth hormone.
T3, insulin, and IGF-1 levels are reduced, while GH and cortisol levels increase.
Glucose initially decreases, followed by gluconeogenesis and protein conservation with fat mobilization.
Electrolyte imbalances include sodium retention and potassium depletion.
Acute malnutrition negatively impacts brain development, reducing neuron numbers, synapses, and myelination, leading to smaller brain size.
These brain effects may be irreversible after the age of 3-4 years.

Clinical Syndromes of Acute Malnutrition

Marasmus - caused by prolonged inadequate energy intake, characterized by wasting of muscle and fat, appearing emaciated and lethargic.
Kwashiorkor - thought to result from insufficient protein but relatively normal calorie intake, characterized by edema, skin lesions, and hair changes.

Management of Malnutrition

Nutritional Interventions:
- Dietary adjustments: Calorie and protein supplements with nutrient-dense foods.
- Oral Nutritional Supplements (ONS): Individualized based on preferences and tolerance.
- Enteral Nutrition: For patients unable to take oral nutrition due to medical conditions.
- Parenteral Nutrition: For severe cases when enteral feeding is not possible.
Pharmacological Interventions:
- Appetite Stimulation: Medications like megestrol acetate or dronabinol might be used to increase hunger.
- Micronutrient Stimulation: Supplementation of vitamins and minerals based on deficiencies.
Monitoring and Follow-Up:
- Regular monitoring of weight, intake, biochemical markers, and clinical signs to evaluate progress.
- Adjustments to interventions based on evaluations.
