METHOD FOR PREDICTION OF MENSTRUAL DYSFUNCTION IN ADOLESCENT GIRLS Russian patent published in 2012 - IPC A61B10/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely paediatrics and gynaecology, and may be used in prediction of menstrual dysfunction in adolescent girls. Physical examinations are held to determine risk factors: dolichostenomelia, scoliosis, kyphosis, lordosis, extremity deformation, thin skin, hemorrhagic manifestations, abnormal occlusion, irregular ear shape, vegetative-vascular dystonia. The stated risk factors are graded and evaluated; thereafter the prognostic coefficients F₁ and F₂ are calculated by formulae: F₁=-7.93+2.16*Z₁+1.58*Z₂+0.92*Z₃+1.32*Z₄+1.27*Z₅+2.61*Z₆+ +1.43*Z₇+2.17*Z₈+1.26*Z₉+1.77*Z_10; F₂=-2.11-1.08*Z₁-0.79*Z₂-0.46*Z₃-0.66*Z₄-0.63*Z₅-1.30*Z₆-0.71*Z₇-1.08*Z₈-0.63*Z₉-0.88*Z₁₀, wherein Z₁ is dolichostenomelia = , wherein X₁: no - 1, yes - 2; ; s=0.4504; Z₂ - scoliosis = , wherein X₂: no - 1, yes - 2; ; s=0.5027; Z₃ - kyphosis = , wherein X₃: no - 1, yes - 2; ; s=0.1054; Z₄ - lordosis = , wherein X₄: no - 1, yes - 2; ; s=0.2072; Z₅ - extremity deformation = , wherein X₅: no - 1, yes - 2; ; s=0.2693; Z₆ - thin skin = , wherein X₆: no - 1, yes - 2; ; s=0.4104; Z₇ - hemorrhagic manifestations = , wherein X₇: no - 1, yes - 2; ; s=0.3535; Z₈ - abnormal occlusion = , wherein X₈: no - 1, yes - 2; ; s=0.4778; Z₉ - irregular ear shape = , wherein X₉: no - 1, yes - 2; ; s=0.4253; Z₁₀ - vegetative-vascular dystonia = , wherein X₁₀: no - 1, yes - 2; ; s=0.4778; and the absolute value F₁ exceeding the absolute value F₂ enables predicting a high risk, while F₁ being less than F₂ shows a low risk of menstrual dysfunction.

EFFECT: method provides higher prediction accuracy in menstrual dysfunction.
