越来越多的儿童表现出代谢综合征（MetS）的特征，包括腹部肥胖、高血压、不良血脂和胰岛素抵抗。健康的饮食习惯在上学期间可能会改善心脏代谢状况，但缺乏证据。在本研究中，在834名丹麦学龄儿童中研究了提供富含鱼类、蔬菜和纤维的学校膳食对MetS评分（主要结局）和个体心脏代谢标志物和身体成分（次要结局）的影响。这项研究是在九所学校进行的随机、对照、非盲、交叉试验。8-11岁的儿童接受新鲜准备的学校午餐和小吃或来自家中的普通盒装午餐（对照），为期3个月。在基线和每个饮食阶段后测量饮食摄入量、体力活动、心脏代谢标志物和身体成分。学校膳食对MetS评分没有影响（P = 1.00）。然而，发现平均动脉压降低了0.4（95% CI 0.0，0.8）mmHg（P = 0.04），空腹总胆固醇浓度降低0.05（95% CI 0.02，0.08）mmol/l（P = 0.001），HDL-胆固醇浓度降低0.02（95% CI 0.00，0.03）mmol/l，TAG浓度降低0.02（95% CI 0.00，0.04）mmol/l（均P
An increasing number of children are exhibiting features of the metabolic syndrome (MetS) including abdominal fatness, hypertension, adverse lipid profile and insulin resistance. Healthy eating practices during school hours may improve the cardiometabolic profile, but there is a lack of evidence. In the present study, the effect of provision of school meals rich in fish, vegetables and fibre on a MetS score (primary outcome) and on individual cardiometabolic markers and body composition (secondary outcomes) was investigated in 834 Danish school children. The study was carried out as a cluster-randomised, controlled, non-blinded, cross-over trial at nine schools. Children aged 8-11 years received freshly prepared school lunch and snacks or usual packed lunch from home (control) each for 3 months. Dietary intake, physical activity, cardiometabolic markers and body composition were measured at baseline and after each dietary period. The school meals did not affect the MetS score (P = 1.00). However, it was found that mean arterial pressure was reduced by 0.4 (95% CI 0.0, 0.8) mmHg (P = 0.04), fasting total cholesterol concentrations by 0.05 (95% CI 0.02, 0.08) mmol/l (P = 0.001), HDL-cholesterol concentrations by 0.02 (95% CI 0.00, 0.03) mmol/l, TAG concentrations by 0.02 (95% CI 0.00, 0.04) mmol/l (both P
