目的初步探讨人群日常饮食的咸味喜好值、钠摄入量与24 h尿钠之间的相关性。方法筛选咸味喜好值低、中、高的对象共12名;为其提供3 d膳食,称重计算其每日钠摄入量,测定24 h尿钠总量;进一步对咸味喜好值、钠摄入量和24 h尿钠总量做相关性分析。结果咸味喜好值和钠摄入量之间呈正相关(r=0.598,P<0.05),每日钠摄入量和24 h尿钠相关性未见统计学差异(r=0.543,P>0.05)。结论通过咸味喜好值的现场测定评估食盐摄入量具有一定的参考价值。
Objective To investigate the relationship between the salty taste preference, sodium intake and 24 h urinary sodium in daily diet. Methods A total of 12 subjects with low, medium, and high salty taste were screened. The dietary supplementation was given for 3 days. The daily sodium intake was weighed and the total amount of urinary sodium was measured. The salty taste preference, Correlation analysis between sodium intake and total 24 h urinary sodium. Results There was a positive correlation between salty taste preference and sodium intake (r = 0.598, P <0.05). There was no significant difference between daily sodium intake and 24 h urine sodium (r = 0.543, P> 0.05 ). Conclusion It is of some value to evaluate the salt intake through the field test of salty taste preference.
