Elderly people, especially those who live in nursing homes, are at high risk for getting osteoporosis and bone fractures. Knowing that an adequate calcium intake is important for prevention and therapy of osteoporosis, we aimed to estimate calcium intake in old people living in nursing homes in Zagreb. In a cross-sectional study, calcium intake was estimated using previously validated food frequency questionnaire especially designed for calcium intake, among 292 nursing homes residents (232 women and 60 men), mean age 82.4±6.5 years. Mean dietary calcium intake in men was 653±297 mg/day and in women 528±279 mg/day (p=0.004). Only 10 % of women and no men were taking calcium supplements. Calcium intake below the 750 mg/day was present in 67.3 % of men and 77.5 % of women. Very low calcium intake, below the half of the recommended value, was present in 18.3 % of men and 31.0 % of women. Milk and dairy products were the main source of calcium intake in our study and contributed more than 80% of total daily calcium intake. No significant correlation was found between the body mass index and calcium intake in both genders. We conclude that the mean calcium intake in nursing home residents was below the recommended values.; Stariji ljudi, pogotovo oni koji žive u domovima za starije osobe, imaju visok rizik obolijevanja od osteoporoze te posljedično lomova kostiju. Obzirom da je primjeren unos kalcija važan čimbenik u prevenciji i liječenju osteoporoze, u ovom presječnom istraživanju smo analizirali unos kalcija u osoba koje žive u domovima za starije osobe u Zagrebu. Korišten je prethodno validirani upitnik, dizajniran za procjenu unosa kalcija. Sudjelovale su 292 osobe, 232 žene i 60 muškarca, prosječne dobi 82,4±6,5 godina, a podaci o unosu kalcija su dobiveni upitnikom. Prosječan unos kalcija je iznosio 653±296 mg/dan u muškaraca i 528±279 mg/dan u žena (p=0,004). Unos kalcija ispod preporučenih vrijednosti od 750 mg/ dan je utvrđen u 67,3 % muškaraca i 77,5 % žena. Vrlo niski unos kalcija, manji od polovine preporučene vrijednosti, je utvrđen u 18.3 % muškaraca i 31.0 % žena. Mlijeko i mliječni proizvodi bili su glavni izvor (više od 80 %) ukupnog dnevnog unosa kalcija u ispitanika. Nije utvrđena značajna povezanost između indeksa tjelesne mase i unosa kalcija u oba spola. Zaključujemo da je prosječni unos kalcija u naših ispitanika koji žive u domovima za starije osobe ispod preporučenih vrijednosti.
