Abstract
Background: In order to improve diet quality, it is important to assess its potential
determinants. Literature indicates young adults attending university engage in unhealthy
behaviour and may be at risk of establishing undesirable dietary habits that continue into later
adulthood. An understanding of the dietary patterns and associated factors in this population is
needed, particularly in New Zealand where the literature is sparse.
Aims: To investigate diet quality and potential influencing factors in a group of university in
New Zealand.
Methods: Diet quality and associated factors were measured in a pilot sample of university
students enrolled at Massey University’s Albany Campus, Auckland, New Zealand. A self-
administered online questionnaire was used to collect data on dietary habits as well as factors
that have been associated with diet quality in previous research. A Diet index was developed
and scored against the dietary recommendations outlined in the Eating and Activity Guidelines
for New Zealand Adults.
Results: Forty university students were recruited in the study. The overall mean diet quality
score was 54.2 (±10.6) points out of 80. The majority of participants met dietary guidelines
for fruit (70%), vegetable (57.5%) and ‘Extra’ food intake (77.5%), while less than half of
participants met dietary guidelines for grains (2.5%), wholegrains (30%), alcohol (40%),
saturated fat (32.5%), added sugar (25%) and added salt (10%). Of the potential influencing
factors investigated, healthy eating attitudes (P=<0.01), binge drinking and use of dietary
supplements (P=≤0.04), food preparation (P=<0.01), as well as confidence in basic cooking
techniques (P=0.05) were significantly associated with diet quality.
Conclusions: The current study identified potential influencing factors as well as components
of the diet in this population that were below dietary recommendations, and findings suggest
university students show clustering of health-related behaviours. This is particularly
concerning given the evidence that university students lack the confidence and/or ability to
prepare meals that contribute to optimal dietary habits, and are likely to engage in binge
drinking; which was negatively associated with diet quality in the current study. Further
research with improved methodology, specifically in regards to the diet quality index used, is
needed to build on the findings in this study.
