Namen študije je bil oceniti prehranski vnos kalcija in vitamina D pri 43 osteoporoznih bolnicah, saj sta to hranili, ki sta ključni za zdravje kosti. V raziskavo smo vključili prostovoljke, ki so opravile antropometrične meritve, izpolnile frekvenčni vprašalnik o pogostosti uživanja živil (FFQ) ter 24-urni priklic jedilnika preteklega dne. Od lečeče zdravnice smo pridobili tudi podatke o T-vrednosti preiskovank, ki je indikator stopnje osteoporoze, ter njihovo število kostnih zlomov. Ocenjen povprečen dnevni vnos vitamina D s hrano je zaskrbljujoče nizek; pri preiskovankah je znašal 72,3 (55,7) IE oz. 1,8 (1,4) µg, kar je znatno manj od priporočil, ki znašajo 800 IE oz. 20 µg. Preiskovanke, ki so prejemale zdravila z vitaminom D (n=32), so v povprečju dosegle 132 % priporočenega dnevnega vnosa vitamina D, preiskovanke, ki zdravil niso prejemale, pa le 5,5 % priporočenega dnevnega vnosa vitamina D. Povprečen dnevni vnos kalcija je pri posameznicah znašal 925 (428) mg, pri čemer je le 41,8 % preiskovank doseglo priporočen dnevni vnos kalcija, ki znaša 1000 mg. Največ so k dnevnemu vnosu kalcija doprinesli mlečni izdelki (624 (401) mg). Statistična analiza ni pokazala značilne povezave med dnevnim vnosom kalcija (p=0,074) oz. vitamina D (p=0,10) ter stopnjo osteoporoze, ovrednoteno s T-vrednostjo. Kljub temu smo opazili boljše doseganje priporočil za dnevni vnos kalcija pri preiskovankah s hudo osteoporozo, kot pri preiskovankah z osteoporozo, kar posredno kaže na pomen osveščanja o pomenu ustrezne prehrane za zdravje kosti.

• Title: Assessment of nutritional intake of calcium and vitamin D in patients with osteoporosis

Abstract

The aim of the study was to assess the nutritional intake of calcium and vitamin D in 43 female patients with osteoporosis, since these are key nutrients for bone health. Anthropometric measurements were performed on the included volunteers, they also had to fill out a food frequency questionnaire (FFQ) and 24-hour recall. We also acquired their T-score, an indication of the severity of osteoporosis, and number oftheir bone fractures from their physician. Mean intake of vitamin D with food was assessed at 72,3 (55,7) IU or 1,8 (1,4) µg, which is alarmingly low, much lower than the recommended daily value of 800 IU or 20 µg. Patients (n=32) who received dietary supplements containing vitamin D successfully increased their daily intake of vitamin D to 132 % of the recommended daily intake. Those who did not receive vitamin D supplementation achieved only 5,5 % of the recommended daily intake. Mean intake of calcium with food was assessed at 925 (428) mg and only 41,8 % of the patients obtained the recommended daily intake for calcium, which is 1000 mg. Dairy products contributed the most to the intake of calcium from food (624 (401) mg). Statistical analysis did not reveal any significant correlation between calcium intake (p=0,074) or vitamin D intake (p=0,10) and the rate of osteoporosis, evaluated with T-score. Nevertheless, the patients with serious osteoporosis had higher intakes of calcium than the patients with osteoporosis. This demonstrates the value of informing patients with osteoporosis about the appropriate nutrition for bone health.
