Abstract

The aim of the study was to determine the impact of demographic and anthropometric parameters on the gastric myoelectrical activity characteristics in a healthy Croatian population. The influence of age, sex, body mass index (BMI) and menstrual cycle phase on the gastric myoelectrical activity characteristics was assessed. The study included 120 healthy subjects of both sexes (60 male and 60 female), divided into four age groups (18-35, 36-50, 51-65 and > 65 years) and three BMI groups (BMI < 25, 25-30 and > 30). Female subjects of reproductive age were divided into three groups according to menstrual cycle phase (day 1-3, day 4-8 and day 9-20 of menstruation). All study subjects underwent percutaneous electrogastrography (EGG) for 60 min before and 60 min after a test meal. The following parameters of the gastric myoelectrical activity were observed: dominant frequency (DF); dominant frequency within normal range (DFNR, %); coefficient of variation for dominant frequency (CVDF); dominant strength (DS. mV); postprandial increase intensity in dominant strength (PPIIDS, %); bradygastria (BG, c/min, %); tachygastria (TG, c/min, %); and arrhythmia (AR). Age was found to influence preprandial but not postprandial DFNR, CVDF and AR. Sex influenced preprandial DF, CVDF, DS and BG, and postprandial DF, CVDF, PPIIDS and TG. BMI exerted an impact on preprandial TG and AR, and postprandial DF, CVDF and AR. The phase of menstrual cycle influenced DF in preprandial period and none of EGG parameters in postprandial period.

Abstract in Croatian

Cilj ove studije je bio odrediti utjecaj demografskih i antropometrijskih parametara na značajke mioelektrične aktivnosti želuca u zdravih ispitanika hrvatske populacije. Ispitivan je utjecaj dobi, spola, indeksa tjelesne mase (BMI) i faze menstrualnog ciklusa (MC) na značajke želučane mioelektrične aktivnosti. 120 zdravih ispitanika oba spola (60 muškaraca i 60 žena) podijeljeno je u četiri dobne skupine (18–35 godina, 36–50 godina, 51–65 godina i više od 65 godina), te prema BMI u tri skupine (BMI<25, 25–30, >30). Žene u generativnoj dobi su bile podjeljene u tri skupine ovisno o fazi MC (1–3. dan, 4–8. dan i 9–20. dan od početka menstruacije). Svim ispitanicima je učinjena perkutana elektrogastrografija (EGG). Snimanje se izvodilo 60 minuta prije te 60 minuta nakon uzimanja testnog obroka. Pratili su se slijedeći parametri mioelektrične aktivnosti želuca: dominantna frekvencija (DF), dominantna frekvencija unutar normalnog raspona (DFNR, %), koeficijent varijacije dominantne frekvencije (KVDF), dominantna snaga (DS, mV), postprandijalni intenzitet porasta DS (PPIPDS, %), bradigastrija (BG, c/min, %), tahigastrija (TG, c/min, %) i aritmija (AR). Životna dob utječe na DFNR, KVDF i AR u preprandijalnom periodu, dok nema utjecaja u postprandijalnom periodu. Utjecaj spola očituje se kroz slijedeće EGG parametre: DF, KVDF, DS i BG u preprandijalnom, te DF, KVDF, PPIPDS i TG u ostprandijalnom periodu. Utjecaj BMI očituje se u TG i AR u preprandijalnom, te DF, KVDF i AR u postprandijalnom periodu. Utjecaj faze MC ogleda se u DF u preprandijalnom periodu, dok nije bilo utjecaja u postprandijalnom periodu.
