Malnutrition: Caused by incorrect amount of nutrient intake Nutritional status: Health status that produced by balanced between requirements and intake Nutritional assessment: Measurement of nutritional status by anthropometrics , biochemical data, dietary history
A) Collect anthropometrics measurements B) Look at biochemical data C) Conduct physical examination to detect the clinical signs of nutritional status D) Obtain a dietary history
Anthropometrics • Height • Weight • Skin fold thickness (triceps, biceps, below scapula, above iliac, and upper thigh) • Circumference (head, mid upper arm, waist, calf, and hip)
Physical growth • Weight for age • Malnutrition (Gomez) • Height for age • Stunting (waterlow) • Weight for height • Wasting • BMI • Obesity
Weight for ageMalnutrition (Gomez) • W/A= W/W(N) x 100 • 90-110 = Normal • 75-89 = 1st, Mild • 60-74 = 2nd , Moderate • <60 = 3rd, Severe
Height for ageStunting • H/A=H/H(N) x 100 • < -2 SD = Stunted, Wasted • > 95 = Normal • 87.5-95= Mild • 80-87.5= Moderate • < 80 = Severe
Weight for heightWasting • W/H= W/W(at same H) x 100 • < -2 SD = Stunted, Wasted • > 90 = Normal • 80-90 = Mild • 70-80 = Moderate • < 70 = Severe
Body Mass Index (BMI) • BMI= W(kg)/ H(m)² • < 15= Underweight • 15-85= Normal • > 85= Overweight • > 95= Obese
