Background: Metabolic syndrome (MetS) is a cluster of metabolic disorders that includes central obesity, hyperinsulinemia, hypercholesterolemia, hypertriglyceridemia and high blood pressure (BP). Statistical reports suggest that the prevalence of MetS has dramatically increased during the recent years and is considered a worldwide epidemic. MetS has been found to be associated with increased risk of all-cause mortality, cardiovascular diseases (CVD), type 2 diabetes mellitus, chronic kidney disease and some types of cancer. MetS has a high socioeconomic cost and it is therefore extremely important that MetS is prevented and treated by simple and feasible methods., Methods: The PreveDi study is a pilot before/after preventive trial aimed at the evaluation of the impact of a brief lifestyle intervention on changes in metabolic syndrome (MetS) risk factors. Recruitment was carried out in two community (council-run) pharmacies in the province of Perugia, Italy and the sample population consisted of 186 adults aged 45 or more who volunteered to participate. At enrolment the participants received a booklet illustrating general recommendations for MetS. During the 6-months follow-up period, participants were invited (by brochures and text messaging on cellular phones) to attend five conferences, five cooking classes, and twelve physical activity sessions. The conferences and the kitchen course were aimed to disseminate a healthy diet strategy focused primarily on reducing glycemic and insulinemic response. At baseline and follow-up MetS parameters were evaluated using medical equipments available in community pharmacies., Results: At baseline, MetS was observed approximately in 52.2% of the PreveDi population, the MetS prevalence decreased with a higher education level in women, but not in men. Attendance to intervention programs was low and there was no significant difference between physical activity recorded at baseline and at follow-up. A slightly increased adherence to the healthy diet recommendations was observed for males. Waist circumference, systolic and diastolic blood pressure, fasting glucose and triglycerides did not change significantly, whereas weight, BMI and total cholesterol did. At follow-up the prevalence of MetS decreased, though not significantly, only in women (from 54,1 to 45.2%). Moreover, in women the negative correlation with education level was lost., Conclusions: This pilot study, even if with some limitations, suggests that MetS can be prevented and/or treated by simple and sustainable methods.
