Food preferences are among the most influential factors of food habits in the vulnerable period of adolescence; in addition, gender-dependent differences in food preferences are also observed. The aim of the present study was to analyze differences in food habits between individuals stratified based on their food preferences in a population-based sample of adolescents aged 15-20. The study was conducted within the Polish Adolescents' COVID-19 Experience (PLACE-19) Study population in a group of 2419 secondary school students who were randomly chosen to participate in the study using a random quota sampling procedure. The food preferences were determined on the basis of a validated Food Preference Questionnaire (FPQ) (which enables assessing preference of vegetables, fruit, meat/fish, dairy, snacks, and starches), whereas food habits were determined on the basis of the Adolescents' Food Habits Checklist (AFHC) (which enables assessing food purchase, preparation, and consumption habits). The analysis involved three homogenous clusters ('low-preferring', 'hedonists', and 'high-preferring'), which were identified using the k-means algorithm. It was found that for a number of the assessed food purchase, preparation, and consumption habits, there were statistically significant differences between the 'low-preferring', 'hedonists', and 'high-preferring' clusters. Within food purchase habits, the food preference influenced frequency of buying pastries/cakes and frequency of eating takeaway meals for all the respondents, while for female respondents, it influenced also choice of desserts in restaurants, and for male respondents, it influenced choosing a low-fat lunch away from home ( < 0.05). Within food preparation habits, the food preference influenced the fat content in desserts at home, the frequency of eating at least one serving of vegetables/salad with an evening meal, the frequency of spreading butter/margarine on bread thinly, and the frequency of having cream on desserts for all the respondents; meanwhile, for female respondents, it also influenced the frequency of avoiding fried foods and the frequency of including chocolate/biscuits in their packed lunch ( < 0.05). Within food consumption habits, the food preference influenced the frequency of eating a dessert/pudding, eating at least one serving of fruit a day, eating at least one serving of vegetables/salad a day, avoiding sausages/burgers, trying to ensure they eat plenty of fruit and vegetables, and frequency of choosing fruit as a snack for all the respondents; meanwhile, for male respondents, it also influenced the frequency of eating sweet snacks and eating at least three servings of fruit most days ( < 0.05). Taking into account that some improper food habits may be typical for the specific clusters, there is an urgent need to analyze and address them for the purposes of public health and to bear in mind that some of those habits are gender-dependent.
食物偏好是青少年这一脆弱时期饮食习惯的最主要影响因素之一;此外,还观察到食物偏好存在性别差异。本研究旨在分析基于食物偏好对人群进行分层后,青少年在饮食习惯方面的差异。该研究是在波兰青少年 COVID-19 经历(PLACE-19)研究人群中进行的,参与者为随机抽取的 2419 名中学生,他们通过随机配额抽样程序被选中参与研究。食物偏好是基于经过验证的食物偏好问卷(FPQ)来确定的(该问卷可评估对蔬菜、水果、肉/鱼、乳制品、零食和淀粉的偏好),而食物习惯是基于青少年食物习惯检查表(AFHC)来确定的(该检查表可评估食物购买、准备和消费习惯)。分析涉及三个同质聚类(“低偏好”、“享乐主义者”和“高偏好”),这些聚类是使用 k-均值算法确定的。研究发现,在所评估的一些食物购买、准备和消费习惯中,“低偏好”、“享乐主义者”和“高偏好”聚类之间存在统计学显著差异。在食物购买习惯方面,食物偏好影响所有受访者购买糕点/蛋糕的频率和外出就餐的频率,而对于女性受访者,它还影响餐厅甜点的选择,对于男性受访者,它还影响外出时选择低脂肪午餐(<0.05)。在食物准备习惯方面,食物偏好影响家庭自制甜点的脂肪含量、晚餐至少吃一份蔬菜/沙拉的频率、将黄油/人造黄油涂在面包上的频率、以及在甜点上加奶油的频率;同时,对于女性受访者,它还影响避免油炸食品的频率以及将巧克力/饼干纳入午餐的频率(<0.05)。在食物消费习惯方面,食物偏好影响吃甜点/布丁的频率、每天至少吃一份水果、每天至少吃一份蔬菜/沙拉、避免香肠/汉堡、尽量确保摄入足够的水果和蔬菜、以及选择水果作为零食的频率;同时,对于男性受访者,它还影响吃甜食的频率和每天至少吃三份水果的频率(<0.05)。考虑到某些不当的饮食习惯可能是特定聚类所特有的,因此迫切需要对这些习惯进行分析和处理,以维护公共健康,并牢记某些习惯是性别相关的。
