This study aimed to identify attitudes, health behaviours, social adjustment and self-reported health of vegetarian and omnivore teenagers and determine characteristics independently related to vegetarian status. Participants were 630 Grade 9 students, ages 13-15 years, in seven schools in Ontario, Canada. Vegetarian status was determined using a 19-item food inventory. The vegetarian group included lacto, ovo and/or lacto-ovo and semi-vegetarians. Omnivores consumed red meat at least monthly. Social adjustment factors included school misbehaviour, low academic performance, authority-defying risks and unsafe/illegal risks. Logistic regression estimated the relationship of characteristics to vegetarian status. The sample comprised 25 vegetarians (4%) and 605 omnivores. Analyses focussed mainly on females; 22 vegetarians and 315 omnivores. Dieting behaviours (current, frequent and past year), alcohol use, poorer social adjustment and poorer self-rated health were positively related to vegetarian eating (p<.05). Among females (using logistic regression), past year dieting (OR 9.88; 95% CI 2.19-44.47) and alcohol use (OR 2.91; 95% CI 1.02-8.32) predominated in the presence of attitudes that personal health and animal rights are very important. The model predicted 79.9% of cases. Teenage vegetarians were distinctive in health behaviours. The independent, positive association of alcohol use with vegetarian eating is a unique and concerning finding. Dieting behaviours were strongly, independently and positively linked to female vegetarian eating. Further studies with a greater range of behaviours would be useful to more fully characterize teenage vegetarians and explore subgroups.
本研究旨在确定素食和杂食青少年的态度、健康行为、社会适应情况及自我报告的健康状况，并确定与素食状态独立相关的特征。研究对象为加拿大安大略省七所学校的630名九年级学生，年龄在13至15岁之间。通过一份包含19项内容的食物清单来确定素食状态。素食组包括乳素食者、蛋素食者和/或蛋奶素食者以及半素食者。杂食者至少每月食用一次红肉。社会适应因素包括学校行为不端、学业成绩低、违抗权威风险和不安全/非法风险。采用逻辑回归分析特征与素食状态之间的关系。样本包括25名素食者（4%）和605名杂食者。分析主要集中在女性身上；22名素食者和315名杂食者。节食行为（当前、频繁和过去一年）、饮酒、较差的社会适应情况和较差的自我健康评分与素食饮食呈正相关（p<0.05）。在女性中（采用逻辑回归分析），过去一年的节食行为（比值比9.88；95%置信区间2.19 - 44.47）和饮酒行为（比值比2.91；95%置信区间1.02 - 8.32）在认为个人健康和动物权利非常重要的态度存在时更为突出。该模型预测了79.9%的情况。青少年素食者在健康行为方面具有独特性。饮酒与素食饮食之间独立的正相关关系是一个独特且令人担忧的发现。节食行为与女性素食饮食密切、独立且呈正相关。对更广泛行为进行进一步研究将有助于更全面地描述青少年素食者并探索亚组。
