AIM
Poor eating habits among young adults are a public health concern. This survey examined the eating habits of undergraduate university students in Finland. We assessed students' dietary intake of a variety of food groups, their adherence to international dietary guidelines (whole sample and by gender), and the associations between importance of eating healthy and dietary guidelines adherence (whole sample and by gender).
METHODS
During the 2013-2014 academic year, 1,189 undergraduate students enrolled at the University of Turku in southwestern Finland completed an online self-administered questionnaire. Students reported their eating habits of 12 food groups, the number of daily servings of fruits/vegetables they consume and how important it is for them to eat healthy. For dietary adherence recommendations, we employed WHO guidelines. Chi-square statistic tested the differences in dietary guidelines adherence between males and females and also the associations between the gradients of importance of healthy eating and the self reported eating habits for each of the food groups, for the whole sample and by gender.
RESULTS
We observed high levels of dietary adherence (>70%) for most of the 'unhealthy food' items (cake/cookies, snacks, fast food/canned food, and lemonade/soft drinks), and moderate adherence for most of the 'healthy food' items (>50%) (dairy/dairy products, fruit/vegetables servings/day, fresh fruit, salads/raw vegetables and cereal/cereal products). Fish/seafood, meat/sausage products and cooked vegetables had levels <50% for adherence to the guidelines. Women had better adherence for meat/sausage products, fast food/canned food and for most 'healthy food' items (p≤0.001), whereas men had better adherence for sweets (difference=12.8%, p≤0.001), lemonade/soft drinks (difference=16.7%, p≤0.001) and fish/seafood (difference=6.6%, p=0.040) compared to women. Most students considered important to eat healthy (78.8%). The importance of eating healthy was significantly associated with adherence for all food groups besides sweets and cake/cookies. These associations remained significant for women but some of them not for men (cereal/cereal products, snacks and sweets).
CONCLUSIONS
The results suggest high adherence to the guidelines mainly for 'unhealthy food' groups, and moderate adherence for healthier food groups. There was also accordance between regarding eating healthy as important and actually eating healthy. However, there are improvements to be considered for specific food groups, as well as gender differences when implementing public health strategies related to food intake.
目的
年轻人不良的饮食习惯是一个公共卫生问题。本调查研究了芬兰大学生的饮食习惯。我们评估了学生对各类食物组的膳食摄入量、他们对国际膳食指南的遵循情况(全样本及按性别划分),以及健康饮食的重要性与膳食指南遵循情况之间的关联(全样本及按性别划分)。
方法
在2013 - 2014学年,芬兰西南部图尔库大学的1189名本科生完成了一份在线自填式问卷。学生报告了他们对12种食物组的饮食习惯、每日食用水果/蔬菜的份数以及健康饮食对他们的重要程度。对于膳食遵循建议,我们采用了世界卫生组织的指南。卡方统计检验了男性和女性在膳食指南遵循方面的差异,以及健康饮食重要程度梯度与全样本及按性别划分的每种食物组自我报告的饮食习惯之间的关联。
结果
我们观察到大多数“不健康食品”项目(蛋糕/饼干、零食、快餐/罐头食品以及柠檬水/软饮料)的膳食遵循水平较高(>70%),而大多数“健康食品”项目(>50%)(乳制品/奶制品、每日水果/蔬菜份数、新鲜水果、沙拉/生蔬菜以及谷物/谷物制品)的遵循水平中等。鱼类/海鲜、肉类/香肠制品和熟蔬菜的指南遵循水平<50%。女性在肉类/香肠制品、快餐/罐头食品以及大多数“健康食品”项目上的遵循情况更好(p≤0.001),而与女性相比,男性在甜食(差异 = 12.8%,p≤0.001)、柠檬水/软饮料(差异 = 16.7%,p≤0.001)和鱼类/海鲜(差异 = 6.6%,p = 0.040)方面的遵循情况更好。大多数学生认为健康饮食很重要(78.8%)。除了甜食和蛋糕/饼干外,表示健康饮食重要性与所有食物组的遵循情况显著相关。这些关联在女性中仍然显著,但在男性中,其中一些关联不显著(谷物/谷物制品、零食和甜食)。
结论
结果表明,主要对于“不健康食品”组,对指南的遵循程度较高,而对于较健康的食品组,遵循程度中等。在将健康饮食视为重要与实际健康饮食之间也存在一致性。然而,对于特定食物组以及在实施与食物摄入相关的公共卫生策略时的性别差异,仍有改进的空间需要考虑。
