Correlationbetweenobesityandsaltintake

Abstract:

Objective：Toexploretherelationshipbetweensaltintakeandobesity.Methods：Twohundredandtwenty-sixhealthypeopleaged18-55yearsfromcommunitiesinChengduwereenrolledinthisstudyfromSeptember2017toJuly2018，including92malesand134non-pregnantfemales.24-hoururineandserumsampleswerecollectedfromhealthypeople，andgeneralinformationwasobtainedthroughquestionnairesurvey.Saltintakeinthepopulationwasestimatedbymeasuring24-hoururinesodiumexcretion.Accordingtothequantityofsaltintake，thepopulationwasdividedintolow-saltintakegroup（<12g/d）andhigh-saltintakegroup（≥12g/d）.Overweightandobesityweredefinedbybodymassindex（BMI）andabdominalcircumference.Thesubjectstasteddiffer－entconcentrationsofsodiumchloridesolutioninalow-to-highorderinthefastingstate，andpointedouttheminimumsodiumchlo－rideconcentration，thusdeterminingthesalttastethreshold.Results：Obesitywascloselyrelatedtohigh-saltintake，whileBMIwasinapositivecorrelationwithsaltintake（P<0.001，r=0.223）.Caseswithoverweightandobesityhadalowersalttastesensitivity，andtheirsaltintakewassignificantlyhigherthanthatofpeoplewithnormalbodyweight[（13.50±0.37）gvs.（15.34±0.47）g，P=0.002]，especiallyinabdominalobesitypatients.Theproportionofobesepeoplewassignificantlyhigherinthepopulationwithhighsaltin－takethaninthepopulationwithlowsaltintake（78.64%vs.31.25%，P=0.016）.Conclusion：Obesityiscloselyrelatedtohighsaltin－take.Overweightandobesepatientshaveincreasedsaltintakeandreducedsalttastesensitivity.Highsaltintakeleadstoanincreaseintheprevalenceofoverweightandobesity.
