To evaluate the feasibility of diet mediterranisation, in a food-at-work context, and its consequence on metabolic syndrome in a mid-age unselected healthy male population group.
One-year longitudinal intervention study. Physical exercise was not modified.
All workers of the Santiago division of 'Maestranza Diesel', a metal-mechanic company servicing the mining industry, were invited to participate.
Initially, 145 workers of a total of 171, of average age 39 years, accepted to participate (sixteen women and 129 men). A subgroup of ninety-six men fully completed the controls programmed for the intervention study. Losses from the original group correspond to missing one control (sixteen), leaving the company (eleven) or blood sampling discomfort (six). The women and sixteen male workers, hired post study initiation, did participate but were excluded from this 12-month analysis.
Diet mediterranisation was successful, reflected in the daily food consumption at the canteen and the evolution of the Mediterranean diet score (MDS) from 4.8 +/- 1.4 to 7.4 +/- 1.5 (limits 0-14). Some metabolic syndrome components showed statistically significant improvement and also statistically significant correlation with the MDS: waist circumference, HDL-cholesterol, systolic and diastolic blood pressure. After 12 months, the reversion rate for metabolic syndrome was 48 % (12/23) with an incidence rate of 4.1 % for new cases (3/73). In total, metabolic syndrome decreased from 24.0 % to 15.6 % (23/96 to 15/96) (P = 0.029).
Diet mediterranisation is feasible in a food-at-work intervention, affecting lunch consumption at the workers canteen and overall consumption evaluated with MDS, together with a significant reduction in metabolic syndrome.
评估在工作场所饮食地中海化的可行性，以及其对中年未选择的健康男性人群代谢综合征的影响。
为期一年的纵向干预研究。不改变体育锻炼。
圣地亚哥分部的“Maestranza Diesel”的所有工人都被邀请参加，这是一家为采矿业服务的金属机械公司。
最初，171 名工人中有 145 名（16 名女性和 129 名男性）接受了参与的邀请。96 名男性的亚组完全完成了干预研究计划的控制。原始组的损失对应于一个控制的缺失（16），离开公司（11）或血液采样不适（6）。研究开始后雇用的女性和 16 名男性工人也参与了研究，但被排除在这个 12 个月的分析之外。
地中海饮食的成功，反映在食堂的日常食物消费和地中海饮食评分（MDS）的演变，从 4.8+/-1.4 到 7.4+/-1.5（0-14 分）。一些代谢综合征的组成部分显示出统计学上的显著改善，并且与 MDS 也有统计学上的相关性：腰围、高密度脂蛋白胆固醇、收缩压和舒张压。12 个月后，代谢综合征的逆转率为 48%（12/23），新病例的发生率为 4.1%（3/73）。总的来说，代谢综合征从 24.0%降至 15.6%（23/96 至 15/96）（P=0.029）。
在工作场所的饮食干预中，地中海饮食是可行的，影响工人食堂的午餐消费和 MDS 评估的整体消费，同时显著降低代谢综合征的发生率。
