METHOD OF DETERMINING INDIVIDUAL UPPER BOUNDARY OF PERSON'S REQUIREMENT OF MACRONUTRIENTS AND ENERGY

摘要

FIELD: medicine.;SUBSTANCE: invention relates to medicine and can be used for the selection of individual diet therapy in treatment-and-prophylactic institutions. For this purpose a patient keeps a diary of physical activity for 7 days with the registration of the passive and active time of the day t_act, t_pas. After that, an averaged coefficient of physical activity CPA_av and an average value of energy consumption E_cpaav for a day are determined. Load testing is carried out in the mode of the step-by-step increasing load with 10 W growth step, 3 minute long step duration, with the maximal load value not exceeding 100 W. Then, a graph showing the dependence of energy consumption on the load value is built and the load value, corresponding to E_cpaav, is determined, at the level of which values of nutrient exchange indices in the process of load testing V_Pcpaav, V_Ccpaav, V_Fcpaav are fixedand taking into account factual indices of nutrients V_Pres,V_Cres,V_Fres and energy consumption at rest E_res, an individual upper boundary of the patient's requirements is determined by formulas: E_ind=k₁E_res+k₂E_cpaav, V_Pind=V_Presk₁+V_Pcpaavk2, V_Cind=V_Cresk₁+V_Ccpaavk2, V_Find=V_Fresk₁+V_Fcpaavk2, where E_ind is the individual index of the person's rational energyexchange (kkal/day);E_res is energy consumption at rest (kkal/day); E_cpaav is the average value of energy consumption under physical load (kkal/day); t_act, t_pas are active and passive time of the day (hour);k₁=t_pas/24 is the coefficient of the passive time of the day; k₂=t_act/24 is the coefficient of the active time of the day; V_Pind, V_Cind, V_Find are individual indices of the nutrient exchange of the person's proteins, carbohydrates and fats (kkal/day); V_Pres, V_Cres, V_Fres are indices of the nutrientexchange of proteins, carbohydrates and fats in the rest state (kkal/day); V_Pcpaav, V_Ccpaav, V_Fcpaav are average indices of the nutrientexchange of proteins, carbohydrates and fats under physical load (kkal/day).;EFFECT: method provides the possibility of evaluating the individual indices of an upper boundary of the person's energy and macronutrient exchange with great accuracy due to the elaboration of a special system of load testing, connected with respiratory calorimetry, making it possible to obtain values of the real day-average requirement of proteins, fats, carbohydrates and energy.;5 dwg, 1 ex
