Abstract

Produljenjem očekivanog trajanja života stanovništvo je sve starije, a time se očekuje u budućnosti porast oboljelih od osteoporoze kao i troškova liječenja te bolesti. Cilj ovoga rada bio je procijeniti unos kalcija kao ključnog nutrijenta za zdravlje kostiju, te analizirati povezanost unosa kalcija i tjelesne aktivnosti s mineralnom gustoćom kostiju i pojavom osteoporoze u štićenika 6 domova za starije i nemoćne osobe grada Zagreba. U istraživanju je ukupno sudjelovalo 256 ispitanika. Upitnik o učestalosti konzumacije hrane i pića (FFQ) korišten je u svrhu procjene dnevnog unosa kalcija, dok su vrijednosti mineralne gustoće kosti određene metodom ultrazvučne denzitometrije. Rezultati pokazuju kako je dnevni unos kalcija bio značajno viši (p=0,004) u muškaraca (653,1 ± 296,7 mg) u odnosu na žene (528,4 ± 279,0) no nijedna skupina ne zadovoljava unos kalcija s obzirom na preporuke. Samo 14,5 % muških te 6,4% ženskih ispitanika ima unos veći od EAR (eng. Estimated Average Requirement; 1000 mg/dan) vrijednosti. Ultrazvučni koštani parametar (QUI) značajno (p=0.004 muškarci; p=0.040 žene) je povezan s tjelesnom aktivnosti u oba spola, dok unos kalcija nije bio značajan prediktor koštane gustoće.

Abstract (english)

The population is getting older so it's expected that the number of people with osteoporosis will grow, as well as the cost of treating this disease. The aim of this paper was to evaluate calcium intake as a key nutrient for bone health and to analyze the correlation between calcium intake and bone mineral activity in 6 nursing homes in Zagreb. A total of 256 respondents participated in this research. Food frequency questionnaire (FFQ) was used to evaluate daily calcium intake while bone mineral density (BMD) values were determined by ultrasound densitometry. Daily calcium intake was significantly higher (higher (p = 0.004) in males (653.1 ± 296.7 mg) compared to women (528.4 ± 279.0), but none of the groups meets calcium intake recommendations. Only 14,5 % male and 6,4 % female subjects have intake greater than EAR (Estimated Average Requirement) values. Ultrasound bone parameter (QUI) significantly (p = 0.004 males, p = 0.040 women) was associated with physical activity in both sexes, while calcium intake was not a significant predictor of bone density.
