Results
In this study, the estimated point of saturation was observed after the fourth focus group session. One additional focus group discussion was conducted to be sure true saturation was established. In total, five focus group discussions have been conducted, consisting of five to ten participants per group. The sample (n = 35) consisted of 14 male and 21 female students with a mean age of 20.6 ± 1.7 yrs (range = 18-26 yrs) and a mean study career of 3.0 ± 1.0 yrs. The majority of students (62.9%) were enrolled in human sciences, whereas respectively 17.1% and 20.0% were enrolled in exact and applied, and biomedical sciences. Additional sample characteristics are described in Table 1.
According to the ecological principles a framework of factors influencing eating (incl. drinking) behaviours in university students was developed based on content analysis of the focus group discussions (Figure 1). The framework consists of four major levels, i.e. individual (intrapersonal), social environment (interpersonal), physical environment (community settings), macro environment, and an additional level of university characteristics. The most appropriate quotes were chosen to illustrate each (sub)category.
