Prekomjerni unos kuhinjske soli je jedan od vodećih čimbenika rizika krvožilnih bolesti. Cilj istraživanja je bio ispitati utjecaj naljepnica upozorenja, postavljenih na kućne spremnike soli, na dnevni unos soli u Mostaru (Bosna i Hercegovina). Uključeno je 150 odraslih, liječenih hipertoničara, nasumice podijeljenih u dvije skupine: kontrolna je dobila samo letak s upozorenjem o štetnosti prekomjernog unosa soli, a interventna i naljepnice upozorenja. Mjerena je 24 satna natriurija (Na 24) i arterijski tlak, na početku istraživanja, te jedan i dva mjeseca kasnije. Ishodni Na24 iznosio je 209,2±78,3 mmol/dan ili 12,3 ± 4,6 g NaCl-a, bez razlika među skupinama (P= 0,745). Nakon jedan i dva mjeseca u interventnoj skupini Na24 je pao na 183 ± 63 i 176 ± 55 mmol (P< 0,001), a u kontrolnoj na 203 ± 60 i 200 ± 58 (P= 0,147). Ukupno sniženje srednjeg arterijskog tlaka je u kontrolnoj skupini iznosilo prosječno 0,7 mm Hg, a u interventnoj 3,6 mm Hg (P= 0,375).
Unos soli je neprihvatljivo visok, čak i u liječenih hipertoničara. Primjenom naljepnica upozorenja taj se unos može bitno smanjiti, no postignuti uspjeh je ipak nedostatan, a dugoročni ishodi nepoznati.Excessive salt intake is a major cardiovascular risk factor. Examined was the impact of enhanced warning on daily salt intake in Mostar (Bosnia and Herzegovina). A sample of 150 treated hypertensives was
randomized in a group receiving a leaflet about the harmful effects of excessive salt, and a group receiving in addition warning stickers for household salt containers. Blood pressure (BP) and 24 h urinary sodium excretion (Na24) were measured at the start of the trial, and one and two months later. The average starting Na24 was 209,2 ± 78.3 mmol,
equivalent to 12.3 ± 4.6 g NaCl, and similar inboth subgroups (P= 0.745). One month and two months later a significant decrease was observed in the intervention group (to 183 ± 63 and 176 ± 55 mmol; P<0.001) but not in the control group (to 203 ± 60 and 200± 58 mmol; P= 0.147). A noticeable decrease in BP (by some 3.6 mm Hg in mean BP; P= 0.375) was observed in the intervention group
only. Salt intake is unacceptably high, even among treated hypertensive subjects. Enhanced warning achieved a marked reduction in Na24 and BP. However, these results are still insufficient and the
long-term effects are unknown
