A sodium intervention project was carried out in Tianjin, China, as part of the Tianjin Project, which is a national pilot, community-based intervention programme to reduce non-communicable diseases. The aim of this 3 year sodium project was to evaluate the feasibility and effects of sodium reduction in the population. The evaluation of the programme was based on examinations of independent cross-sectional population samples in 1989 (1719 persons) and in 1992 (2304 persons) in the intervention and matched reference areas. Food weighing and consecutive 3 day food records were used to measure dietary intake. The mean sodium intake fell 22 mmol/day in men and 11 mmol/day in women in the intervention area from 1989 to 1992. The reduction was significant in men (P = 0.001) and near significance in women (P = 0.05). The sodium intake increased significantly in men in the reference area. There was a significant net reduction in sodium intake in men in the intervention area. This reduction was similar in different educational and occupational groups suggesting that the intervention had reached the whole community. The mean systolic blood pressure (SBP) decreased 3 mm Hg for the total population and 2 mm Hg for normotensives in the intervention area. There was a significant net reduction in SBP both in all or in normotensive subjects. These results support the conclusion that community-based sodium intervention is feasible for hypertension prevention. However, the sodium intake is still very high in this population, which warrants further effective intervention.
作为“天津项目”的一部分,在中国天津开展了一项钠干预项目。“天津项目”是一项全国性试点、基于社区的干预计划,旨在减少非传染性疾病。这个为期3年的钠项目旨在评估人群中减少钠摄入的可行性和效果。该项目的评估基于对1989年(1719人)和1992年(2304人)干预地区及匹配对照地区独立横断面人群样本的检查。采用食物称重法和连续3天的食物记录来测量饮食摄入量。从1989年到1992年,干预地区男性的平均钠摄入量下降了22 mmol/天,女性下降了11 mmol/天。男性的下降具有显著性(P = 0.001),女性接近显著性(P = 0.05)。对照地区男性的钠摄入量显著增加。干预地区男性的钠摄入量有显著的净减少。不同教育和职业群体的减少情况相似,这表明干预措施覆盖了整个社区。干预地区总人群的平均收缩压(SBP)下降了3 mmHg,血压正常者下降了2 mmHg。所有受试者或血压正常者的SBP均有显著的净下降。这些结果支持了基于社区的钠干预对预防高血压是可行的这一结论。然而,该人群的钠摄入量仍然非常高,这需要进一步有效的干预。
