在队列研究中评估了蔬菜消费与肥胖测量之间的关系。从成立到2018年10月，对七个数据库进行了搜索。个体研究的质量使用乔安娜布里格斯研究所队列研究关键评估工具进行评估。采用建议分级评估、发展和评价（GRADE）系统来确定证据体的质量。纳入了10项研究。六项研究测量了蔬菜摄入量随时间的变化。其中2项研究表明，增加蔬菜摄入量导致4年内体重减轻0.09-0.1 kg （p < 0.001）。在其他研究中，增加蔬菜摄入量也与体重增加、超重或肥胖的风险降低有关（优势比（or）从0.18到0.88不等）。四项研究仅在基线上测量蔬菜摄入量。一项研究表明，每天摄入40份蔬菜可以降低体重增加的风险(OR为0.27(95%可信区间（CI） 0.08-0.99)，另一项研究发现，蔬菜摄入量与女性腰围呈负相关（每天每份蔬菜摄入量为- 0.36厘米）。本综述为成人蔬菜摄入量与体重相关结局之间的负相关提供了中等质量的证据。当这些发现与蔬菜消费没有明显的危害相结合时，证据基础可以以可接受的信心来指导实践和政策。
The relationship between vegetable consumption and measures of adiposity was assessed in cohort studies. Seven databases were searched from inception until October 2018. The quality of individual studies was assessed using the Joanna Briggs Institute Critical Appraisal of Cohort Studies tool. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) system was applied to determine the quality of the body of evidence. Ten studies were included. Six measured change in vegetable intake over time. Two showed that increasing vegetable consumption resulted in weight loss of 0.09–0.1 kg over four years (p < 0.001). Increased vegetable intake was also associated with a reduced risk of weight gain and overweight or obesity (Odds ratios (ORs) ranged from 0.18 to 0.88) in other studies. Four studies measured vegetable intake at the baseline only. One showed that intakes >4 servings/day reduced the risk of weight gain (OR 0.27 (95% confidence interval (CI) 0.08–0.99) and another found an inverse association with waist circumference in women (−0.36 cm per vegetable serving/day). This review provides moderate quality evidence for an inverse association between vegetable intake and weight-related outcomes in adults. When these findings are coupled with no apparent harm from vegetable consumption, the evidence-base can be used with acceptable confidence to guide practice and policy.
