Impact of sports participation on cardiovascular health markers of children and adolescents: Systematic review and meta-analysis

BACKGROUNDCardiovascular diseases have a high prevalence in adults and their development begins in the first decades of life. On the other hand, sports participation in childhood and adolescence provides benefits which can delay the onset of these diseases.AIMTo synthesize the available literature on the impact of sports participation on cardiovascular outcomes in children and adolescents.METHODSThis systematic review was conducted on studies of children and adolescents (aged 8-18 years) who regularly practiced a sport and had reported cardiovascular outcomes (blood pressure and intima-media thickness) recorded. The Medline/PubMed, SciELO, Reference Citation Analysis (https://www.referencecitationanalysis.com/) and Bireme databases were searched.RESULTSIn total, 3314 publications for blood pressure and 122 publications for intima-media thickness were identified in the databases. After exclusions (e.g., duplicate articles, animal studies and those that did not meet the inclusion criteria), four publications for blood pressure (449 adolescents) and two publications for intima-media thickness were included (402 adolescents). For blood pressure, all publications were longitudinal in design (follow-up ranging from 12 wk to 12 mo) and involved adolescents aged from 8 years to 18 years of age. For intima-media thickness, both publications were longitudinal in design and involved adolescents aged from 11 years to 18 years of age.CONCLUSIONSports participation seems to promote benefits to cardiovascular structure and function in adolescents. However, studies with adolescents are scarce and further research is needed to understand this phenomenon.     

高脂血症与颈总动脉内中膜厚度的相关研究

目的探讨脑梗塞患者高脂血症与颈总动脉内中膜厚度（IMT）之间关系。方法随机选择不同程度脑梗塞患者219例,常规进行血脂三项指标（TCH、TG、LDL）检查,根据结果将其分成三组,组1：血脂三项指标均正常。组2：血脂三项指标中有任意二项不同程度增高。组3：血脂三项指标均明显增高。然后分别行彩色多普勒超声检测和颈总动脉内中膜厚度及是否有斑块形成,最后用统计学多种方法分析高脂血症与IMT厚度及动脉硬化斑块之间关系。结果219例脑梗塞患者中,组1（50例）,IMT≤1．0,斑块形成2例。组2（81例）．1．0〈IMT≤1．3,斑块形成57例,组3（88例）,IMT≥1.3,全部患者均有斑块形成。结论高脂血症是致颈总动脉内中膜增厚的主要因素,是斑块形成的基础,是诱发心脑血管疾病的根源。
