Materials and Methods
Study Design: This study employed a randomized controlled trial (RCT) design to assess the impact of a Mediterranean diet intervention on cardiovascular health markers. The study duration was six months, with participants randomly assigned to either the intervention group, receiving the Mediterranean diet, or the control group, following their usual diet.
Participants: A total of 200 participants aged 30-65, with a history of cardiovascular risk factors but no diagnosed cardiovascular disease, were recruited. Inclusion criteria included BMI between 25 and 35 kg/m² and at least one cardiovascular risk factor such as hypertension or elevated cholesterol. Exclusion criteria included diagnosed cardiovascular disease, dietary restrictions, or chronic illnesses impacting dietary habits.
Dietary Intervention: Participants in the intervention group received comprehensive dietary guidelines based on the Mediterranean diet, focusing on high consumption of fruits, vegetables, whole grains, and lean proteins, particularly fish, with minimal processed food and red meat. They also attended bi-weekly nutritional counseling sessions for the study duration. The control group received no dietary modification or counseling.
Data Collection: Baseline data collection included demographic information, dietary habits, and cardiovascular health markers, including blood pressure, lipid profile, and body mass index (BMI). Follow-up measurements were taken at three and six months.
Statistical Analysis: Data were analyzed using SPSS software (version 26.0, IBM Corp). Descriptive statistics were used to summarize participant characteristics. Differences in cardiovascular markers between baseline and follow-up within and between groups were analyzed using paired and unpaired t-tests, respectively. A p-value of less than 0.05 was considered statistically significant. Multivariate regression analysis was conducted to adjust for potential confounders like age, sex, and baseline values.
Ethical Considerations: The study protocol was approved by the Institutional Review Board (IRB). Written informed consent was obtained from all participants before enrolment in the study.
