Height and body mass index in Oslo, Norway, compared to other regions of Europe: do they explain differences in the incidence of hip fracture? European Vertebral Osteoporosis Study Group.
Lean body stature and tallness have both been identified as risk factors for hip fracture. In this study, height and weight data from a multinational multicenter study were used to compare Oslo, which has some of the highest incidence rates of hip fracture ever reported, to other regions of Europe, with respect to height and body mass index. More than 17,000 subjects in six age strata (50-54, 55-59, 60-64, 65-69, 70-74, 75+ years) from 36 centers in 19 European countries were enrolled in the European Vertebral Osteoporosis Study (EVOS), which included standardized height and weight measurements. We found that men in Oslo were 4.3 cm taller than men in western Europe, 5.0 cm taller than men in eastern Europe, and 8.6 cm taller than men in southern Europe. Oslo women were also taller, by 2.2 cm compared to women in western Europe, 2.7 cm compared to women in eastern Europe, and 5.2 cm compared to women in southern Europe. In all age groups, except women aged 55-59 years, mean body mass index (BMI) was lowest in Oslo. Nearly twice as many had a BMI less than 22.0 kg/m2 in Oslo compared to the other regions combined (11.1% vs. 6.6% in men and 19.2% vs. 9.9% in women). This study indicates that the people of Oslo are taller and leaner than people in other regions of Europe. This may in part explain the higher incidence of hip fracture in the population of Oslo.
