Abstract

Introduction: vegan diets are currently an essential topic of discussion because they are recognized as a prototype of a healthy diet but are also associated with deficits in the intake of critical nutrients such as protein. Evaluating the factors that influence the deficit in their intake in vulnerable populations such as university students represents an important topic of interest, considering that this is one of the groups where veganism is most popular. Given this, the present study aimed to determine the degree of protein sufficiency and its associated factors in a sample of Chilean vegan university students. Materials and methods: an exploratory cross-sectional study was conducted on 114 vegan university students who responded to an online survey on academic, attitudinal, clinical, dietary, and sociodemographic variables. Protein intake was calculated, and based on self-reported weight, daily protein adequacy was calculated according to the recommendation of 0.9 g/kg/day. Finally, the association between protein adequacy and previously consulted variables was calculated by determining the odds ratios. Results: only 53.5 % had adequate daily protein intake, which was associated with the length of time respondents had been vegan (OR, 2.86; 95 % CI, 1.07 to 7.34; p < 0.05), use of supplements (OR, 5.24; 95 % CI, 1.17 to 25.2; p < 0.05), and the frequency with which they ate lunch at home (OR, 87.7; 95 % CI, 24.1 to 304; p = 0.000). Conclusion: there needs to be more protein adequacy in the assessed sample. Protein adequacy is associated with the length of time on the vegan diet, frequency of eating lunch away from home, and use of supplements regularly.
