简要总结
The PRENAV project focuses on healthy and sustainable eating among employees in the defense sector of the Republic of Slovenia. The project pursues two main objectives:
- In a selected sample of employees in the defense sector, the project will determine their nutritional status and assess indicators of metabolic health, including serum concentration of vitamin D.
- In the selected sample, through a survey and qualitative methods (interviews, focus groups), we will identify the eating habits of employees in the defense sector, the factors influencing their dietary decisions, and the barriers and facilitators of healthy and sustainable eating among employees in the defense sector.
Based on these findings, we will prepare recommendations and an action plan to promote healthier and more sustainable eating among employees in the defense sector.
详细描述
Participants will be selected using non-probability quota sampling, with quotas defined according to population characteristics, taking into account the research problem:
- Proportional representation based on the permanent composition of employees in the defense sector: soldiers, non-commissioned officers, officers, and military staff (military personnel 70%) and civilian employees (30%).
- Eating habits (canteens) during working hours: based on the number of employees at each military barracks (n=13) and at the Ministry of Defence.
- Gender structure of the observed population: military personnel 85% male and 15% female; civilian employees according to the gender distribution data of the civilian workforce.
- The purpose of this sampling strategy is to proportionally capture those characteristics of the military and civilian population employed in the defense sector that are crucial for the research objectives, namely: employment structure, gender distribution, and eating habits in canteens.

结局指标
主要结局
Food intake
时间窗: From enrollment to the end of the November 2025
Participants of the cross-sectional study will complete a Food Frequency Questionnaire (FFQ), adapted for the Slovenian population (Bizjak, Jenko Pražnikar \& Koroušić Seljak, 2014), with the aid of visual materials (portion size images). In the FFQ method, respondents answer questions about the frequency of consumption of specific foods over a certain period of time. From a methodological perspective, most studies examining dietary habits and food/nutrient intake in military populations use the Food Frequency Questionnaire (FFQ), which is typically adapted to the general population of individual countries (Collins et al., 2021), rather than specifically tailored to the military population. The questionnaire is based on self-reporting by study participants. It is an internationally established methodology for subjective assessment of nutrient intake, and the risk for participants is negligible.
