一项旨在评价减盐措施在农民中实施的可行性及效果的小型干预试验结果表明：在参加试验的１６户（共３８人）农民中，经过１２周的干预，膳食盐摄入量由干预前的平均１１．１±３．７ｇ／日下降到６．１±１．７ｇ／日，平均下降了５．０ｇ／日。其中来自高盐食物（如咸菜、泡菜、豆豉等）的盐平均下降了３．９ｇ。８小时夜尿钠及钠／钾比值也相应下降，但无统计学显著性。干预第４周后，血压出现显著性下降，第８周、第９周达最低点。与干预前相比，干预后收缩压平均下降１．７ｋＰａ（１２．５ｍｍＨｇ），舒张压平均下降１．０ｋＰａ（７．８ｍｍＨｇ），Ｐ值均＜０．０１）。上述结果说明：在足够的干预强度下，简单、明确、具体的膳食减盐指导能够在农民中行之有效地开展并取得良好效果。
A small-scale intervention trial to evaluate the feasibility and effectiveness of the salt reduction measures implemented among farmers showed that among the 16 households (38 persons) participating in the experiment, after 12 weeks’ intervention, the dietary salt intake increased from Average pre-intervention 11.1 ± 3.7g / day dropped to 6.1 ± 1.7g / day with an average decrease of 5.0g / day. Among them, salt from high-salt foods such as pickles, pickles, beans, etc. dropped by an average of 3.9g. 8-hour night urine sodium and sodium / potassium ratio also decreased, but not statistically significant. After the fourth week of intervention, the blood pressure decreased significantly, reaching the lowest point at the 8th week and the 9th week. Compared with that before intervention, systolic blood pressure decreased by 1.7kPa (12.5mmHg) on average and diastolic blood pressure decreased by 1.0kPa (7.8mmHg) on average, P <0.01). The above results indicate that simple, clear and specific dietary salt reduction guidance can be effectively and effectively implemented among farmers with sufficient intervention intensity.
