Background: Fruit and vegetable consumption is infrequent among adolescents, and the possible effect of this consumption on cardiovascular health during this age group is undefined. Aim: To investigate the association between fruit and vegetable consumption on cardiovascular risk indicators in adolescents (abdominal obesity, hyperglycemia, hypertriglyceridemia, dyslipidemia, hypertension and metabolic syndrome). Methods: This systematic review was registered in PROSPERO (CRD42013004818), and a systematic review searching electronic databases (Biomed Central, CINAHL, MEDLINE, PsycINFO, Scopus, Web of Science) from inception to December 7, 2015 was conducted. The search strategy used the following sets of descriptors related to: age group; fruits and vegetables; cardiovascular risk indicators; cross-sectional and cohort studies. Eligibility criteria were: Articles in English, Spanish and Portuguese; original studies; sample of adolescents (10-19 year-old according to World Health Organization); descriptors according to the cardiovascular risk indicators. Potentially eligible articles were selected by two reviewers separately. Results: A total of 5632 articles were identified. After reading the titles and abstracts, 102 potentially relevant articles remained for full reviewed. After selection, 11 articles meeting the inclusion criteria were included (10 cross-sectional; 1 cohort). The main reasons for study exclusion were misclassifying adolescence, assessing fruits and vegetables as part of a food pattern (for example, together with fish, dairy, or cereal), and cardiovascular risk indicators that were not specified or that differed from the definitions established. Articles evaluated fruit and vegetable intake in diverse units, using food frequency questionnaires (54.5%), 24-hour-dietary-recalls (27.3%), and food records (18.2%). In addition, fruit and vegetable consumption were assessed separately (54.5%), together (36.4%), or only vegetables (9.1%); and 1 article included fruit juice (9.1%). A third of the studies showed significant inverse associations of fruit and vegetable intake with systolic blood pressure, abdominal obesity, triglycerides, HDL cholesterol, and metabolic syndrome. Conclusion: The associations between fruit and vegetable consumption and adolescent cardiovascular risk indicators are inconsistent. Since the benefits of this consumption are well established in adult cardiovascular health, further studies are necessary, addressing high methodological quality to better understand this phenomenon in adolescents (AU)
