Sažetak

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.
