Abstract

Introduction: Vegetarianism in its various forms has gained global recognition in part because of the notion that it is healthier; however, associations between plant-based diets and selected lifestyle practices in Israel have yet to be clarified. Methods: A population-based sample consisting of 1396 Israeli adults was collected via telephone survey, between the years 2013-2014. Differentiation between self-defined and actual vegetarians was initially verified (based on food intake). Next, “actual” vegetarian status was studied in relation to demographics and health behaviors. Results: Approximately 5% (N = 65) of respondents (5.8% Jews and 3.0% Arabs) were “self-defined” vegetarians; but only about half (N = 33) adhered to genuine vegetarian diets. By contrast, nearly 2% (N = 26) of those self-identified as non-vegetarians were “actual” vegetarians; thus, 4.4% (N = 59) of the sample were verified “vegetarians.” And while socio-demographic features did not meaningfully capture differences by vegetarianism status, “actual” vegetarians were significantly more likely than non-vegetarians to be physically active (OR = 1.7), use nutritive supplements (OR = 2.4) and read food product labels (OR = 1.9; all P < .01). Conclusions: Aggregately, “actual” vegetarian participants were more inclined to have healthier lifestyle practices relative to their non-vegetarian counterparts. Forthcoming research using larger samples should however exploit constant assessment measures to validate the link between vegetarianism and health-promoting correlates.
一项全国性研究中的素食主义流行率和生活方式相关因素
导言:各种形式的素食主义在全球范围内得到认可,部分原因是素食主义更健康;然而,在以色列,以植物为基础的饮食与特定生活方式之间的关系尚待澄清。研究方法通过电话调查收集了 2013-2014 年间 1396 名以色列成年人的人口样本。首先核实了自我定义的素食者和实际素食者之间的区别(基于食物摄入量)。接下来,研究了 "实际 "素食者身份与人口统计学和健康行为的关系。研究结果约 5%(N = 65)的受访者(5.8% 犹太人和 3.0% 阿拉伯人)是 "自我定义的 "素食者;但只有约一半(N = 33)的受访者坚持真正的素食。相比之下,近 2%(N = 26)自我认定为非素食者的人是 "真正的 "素食者;因此,样本中有 4.4%(N = 59)是经过验证的 "素食者"。虽然社会人口学特征不能有效反映素食者身份的差异,但 "实际 "素食者比非素食者更有可能参加体育锻炼(OR = 1.7)、使用营养补充剂(OR = 2.4)和阅读食品标签(OR = 1.9;均为 P < .01)。结论总体而言,"实际 "素食者比非素食者更倾向于采用更健康的生活方式。不过,即将进行的研究应使用更大的样本,利用恒定的评估措施来验证素食主义与促进健康的相关因素之间的联系。
