(4) Dairy food costs. The AZ 628 chemical structure results of the sensitivity analyses are expressed in the outcome measures of DALYs lost and total costs avoided. Results Table 1 shows the data used as input in the model. For the sake of clarity,
the table pools the data from both sexes and all age categories. In the model itself, all input variables were divided into sex and age categories (i.e. 50–54, 55–59, 60–64, 65–69, 70–74, 75–79, 80–84, ≥85 years). The risk factor for a hip fracture due to low calcium intake was based on a study by Cumming et al., and amounted to 1.08 [37]. The incidence of hip fractures in both men and women in Sweden appeared to exceed that of The find more Netherlands and France. Moreover, in all countries, it shows that the incidence of hip fractures in women is higher compared with men. Furthermore, the incidence of hip fractures and mortality rates after hip fracture increase substantially with age especially in the age categories of 70 and above. As explained above, the mortality figures click here in Table 1 refer to the mortality after
hip fracture in the general population. It appeared that, up to the age of 80 years, the mortality data for Sweden exceed those for The Netherlands and France, probably because of the high incidence rates of hip fracture in Sweden compared to the other countries. In the first year after hip fracture, the average loss of quality of life (‘utility’) was calculated at 0.22; while in the following years, the average loss of quality of life was 0.08.
