To investigate the determinants of vegetable intake in urban socio-economically disadvantaged adolescents to inform the development of an intervention programme.
A narrative systematic review was carried out by searching five electronic databases from 2013 to 2020. The descriptors used for the search strategy were vegetable intake, adolescents, determinants and correlates. Inclusion criteria were including a sample of socio-economically disadvantaged adolescents aged 12-18 years, evaluation of the association between vegetable intake and determinants of intake, and conducted in urban settings of high-income countries. Thirteen studies met the inclusion criteria. Identified determinants of vegetable intake were reported according to the five levels of the socio-ecological model of health.
Studies included in the review were conducted in four countries: USA (n 8), Australia (n 3), Ireland (n 1) and New Zealand (n 1).
Adolescents aged 12-18 years from socio-economically disadvantaged backgrounds living in urban settings.
Thirty-nine determinants were identified. Nutrition knowledge was the only determinant consistently investigated in several independent samples which was not associated with vegetable intake in socio-economically disadvantaged adolescents. For the remaining potential determinants, it was not possible to examine the consistency of evidence as there were not enough studies investigating the same determinants. Most of the studies followed a cross-sectional design and were carried out in school settings.
There is a need for further studies on the determinants of vegetable intake in this population preferably with longitudinal designs and beyond the school setting in different countries to guide the development of successful interventions.
调查城市社会经济条件不利的青少年蔬菜摄入量的决定因素，以为干预计划的制定提供依据。
通过检索2013年至2020年的五个电子数据库进行叙述性系统评价。搜索策略使用的描述词为蔬菜摄入量、青少年、决定因素和相关因素。纳入标准包括有12至18岁社会经济条件不利青少年的样本、对蔬菜摄入量与摄入决定因素之间关联的评估，且研究在高收入国家的城市环境中进行。13项研究符合纳入标准。根据健康社会生态模型的五个层面报告了已确定的蔬菜摄入量决定因素。
纳入评价的研究在四个国家进行：美国（8项）、澳大利亚（3项）、爱尔兰（1项）和新西兰（1项）。
居住在城市环境中、社会经济背景不利的12至18岁青少年。
确定了39个决定因素。营养知识是在几个独立样本中一直被调查的唯一决定因素，它与社会经济条件不利的青少年的蔬菜摄入量无关。对于其余潜在决定因素，由于没有足够多的研究调查相同的决定因素，因此无法检验证据的一致性。大多数研究采用横断面设计，且在学校环境中进行。
有必要对该人群蔬菜摄入量的决定因素进行进一步研究，最好采用纵向设计，并在不同国家的学校环境之外进行，以指导成功干预措施的制定。
