Idenfying Dietary Paerns in Respect to Ultra-Processed Food (UPF) In French And Bulgarian Elderly Populaon: A Pilot Study
The consumpon of ultra processed food (UPF) has been rapidly increasing globally. This is
concerning, as UPFs are characterised by high levels of sugar, fat, sodium and has been associated
with the increasing prevalence of obesity and non-communicable diseases (NCDs). Despite the
growing concern over UPFs, there has been lile aenon given to UPF consumpon in elderlies,
who are parcularly vulnerable due to physiological declines associated with ageing. This study aims
to idenfy dietary paerns in respect to UPF in French and Bulgarian elderlies, compare the number
of food choices in each NOVA category between the different dietary paerns within each study
populaon and possible sociodemographic determinants associated with the dietary paerns. A
self-administered semi-quantave finite food choice and frequency web-based quesonnaire was
distributed. The datasets were run through mulple correspondence analysis (MCA). All resulng
dimensions from MCA were included in a subsequent hierarchical cluster analysis (HCA) to idenfy
clusters with similar dietary paerns. Three dietary paerns were idenfied in both French and
Bulgarian elderlies. Idenfied dietary paerns in French elderlies were: “Health-conscious”,
“Convenience food” and “UPF oriented’’. Idenfied paerns in Bulgarian elderlies were “Tradional
diet”, “No cooking” and “UPF oriented”. The “UPF oriented” dietary paern of the French elderlies
had a significantly higher number of UPF food choices compared to the “Health-conscious” dietary
paern (7.36 ± 2.01 vs 3.90 ± 1.95, p=
