Effects of nutritional education on metabolic syndrome parameters in a sample of adults in Subotica, Northern Serbia

The aim of this study is to assess the changes in metabolic syndrome parameters among adults after the implementation of nutrition education. The research was conducted as a prospective, longitudinal, quasi-experimental evaluation study from May to December 2022. The research sample included 31 employees at the College of Vocational Studies in Subotica. The study was conducted in three phases: Initial assessment (anthropometric, clinical, biochemical measurements and eating habits), Nutrition educations (onloine and face-to-dace) and Evaluative assessment (six months after the initial assessment). Data analysis included methods of descriptive and comparative statistical analysis. Nutrition education was conducted for 31 participants, but only 18 responded to the evaluative assessment. Two thirds (62%) of the participants were overweight ad had elevated cholesterol levels. Elevated triglyceride values were registered in more than a half of the participants and high blood glucose levels in 13% of participants. More than a third of the participants had three or four risk factors for the development of metabolic syndrome. After nutrition education, distribution of participants according io BMI significantly changed (I—normal: 37%; overveigt: 31%; obese:29%; E—normal:10%; overveigt:29%; obese:19%; p = 0,001). Significant changes in the distribution of total cholesterol levels (I: 5.7 mmol/l; E: 5.4 mmol/l) was determined at the evaluative assessment (p = 0.005). Statistically changes in the distribution of breakfast (p = 0.001) and vegetables (p = 0.013) intake were observed. There were not determined significant changes in other antropometric, clinical and biochemical parameters after nutrition education. Although the nutrition education intervention showed some changes in the prevalence of risk factors, significant changes require more intensive, long-term interventions tailored to individual needs.
