Objective: The incidence of osteoporosis increases with age and is most frequently observed in postmenopausal women. The objective of the present population-based cohort study was to assess the influence of Ca intake from dairy sources on hip bone mineral density and hip fracture incidence in a group of Polish women over 55 years of age. Design: The main outcome measures included: bone mineral density, the number of previous fractures and the reported Ca intake from dairy sources, assessed by a diet questionnaire. Setting: The RAC-OST-POL Study was conducted in the District of Raciborz in the south of Poland. Subjects: The study was carried out in a group of 625 women, randomly recruited from the general population of women aged >55 years. Results: Median Ca intake from dairy products was lower in the group of women with femoral neck T-score <=-2 center dot 5 than in the group with T-score >-2 center dot 5 (275 v. 383 mg/d; P = 0 center dot 0019). For total hip score, the difference was close to borderline significance (P = 0 center dot 0698). Median Ca intake from dairy products was lower in the group of women with previous fractures than in those without fracture history (336 v. 395 mg/d; P = 0 center dot 0254). The main dairy source of Ca in the analysed group included milk drinks, rennet cheese and milk. Conclusions: Higher dairy Ca intake is recommended, since a number of the women analysed were unable to satisfy their Ca requirement exclusively from their diet.
