METHOD FOR PREDICTION OF RISK OF DEVELOPING PROTEIN-ENERGY MALNUTRITION IN THREE-YEAR-OLD CHILDREN BORN WITH EXTREMELY LOW BODY WEIGHT Russian patent published in 2024 - IPC A61B5/02 A61B5/103 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to paediatrics and neonatology, and can be used to predict the risk of developing protein-energy deficiency in three-year-old children born with extremely low body weight. Following parameters are determined: child’s body weight at birth (weight), gestational age at birth (GA), presence/absence of fetoplacental and/or uterine-placental blood supply (FPBS) and presence/absence of infant artificial feeding (AF) at stationary stage of nursing. Prognostic coefficient (z) is calculated as a classification value of the regression equation by formula: z = −1.9+K₁×GA+(K₂×Weight)+K₃×FPBS+K₄×AF, where −1.9 is a constant for this set; GA is gestational age, weeks; Weight is birth weight, g; FPBS is presence of fetoplacental and/or uterine-placental blood supply in anamnesis: 1 is presence, 0 is absence; AF is artificial feeding at the stationary stage of nursing: 1 is presence, 0 is absence; coefficients of variables (β): K₁= 0.246; K₂ = (−0.007); K₃ = 0.887; K₄ = 0.864. Then the probability of developing protein-energy deficiency (p) is calculated by formula: , where z is the value of the regression equation, e = 2.718. If the p value is more than 0.6, a high risk of developing protein-energy deficiency is predicted; if the value of p is from 0.6 to 0.3, the average degree of risk is determined; and if p is less than 0.3, a low risk of developing protein-energy deficiency is predicted.

EFFECT: method provides higher prediction accuracy due to specifics of determining and subsequent calculation of diagnostic values.
