Bone Loss Rate

Aim was to investigate fracture risk (FR) according to bone loss (BL) rate. A random sample of 1652 women aged 53.5 years was measured with dual X-ray absorptiometry in femoral neck in 1989 and 1994 and divided into tertiles of annual BL rate: high >0.84%, moderate 0.13%–0.84%, and low <0.13%. Low trauma energy fractures during following 10 years were recorded. There were no differences in FR between BL tertiles in Cox regression model. Factors predicting lower FR in Cox model were in high tertile: high T-score (HR 0.71; 95% CI 0.54–0.93,P=.012), no sister's fracture (HR 0.35; 0.19–0.64,P=.001), no mother's fracture (HR 0.52; 0.31–0.88,P=.015), in moderate tertile: high T-score (HR 0.69;0.53–0.91,P=.008) and good grip strength (HR 0.98; 0.97–0.99,P=.022). In low tertile there were no predictors for FR. BL predicted FR in women with mother's fracture in univariate and multivariate model (OR 2.6; 1.15–5.7,P=.021) but with sister's fracture this was observed only in multivariate model (OR 2.66; 1.09–6.7,P=.039). Accordingly, the risk factors for postmenopausal fractures, especially mother's fracture, may interact with BL.

Vitamin D deficiency is common in non-Western immigrant groups living in Western countries. A comparison of vitamin D status in individuals who have emigrated and individuals who remain in their country of origin is needed in order to provide information about the effect of moving to northern latitudes. A total of 196 participants aged 30–60 years in a cross-sectional population-based study in Kandy, Sri Lanka (latitude 7° north) and 242 Sri Lankans aged 31–60 years participating in a cross-sectional population-based study in Oslo, Norway (latitude 60° north) were included in the analysis. All serum samples were analysed for serum 25-hydroxyvitamin D (s-25(OH)D) in the same laboratory. Sri Lankans living in Norway had substantially lower s-25(OH)D (mean 31·5 nmol/l) compared with those living in Sri Lanka (mean 54·2 nmol/l), and the prevalence of s-25(OH)D <  25 nmol/l was 9·3 times higher (95 % CI 4·4, 19·6) in Norway compared with Sri Lanka. In Sri Lanka there was a clear seasonal variation with the lowest s-25(OH)D levels in August–September and the highest levels in November–December. We conclude that vitamin D status among Sri Lankans living in Kandy, Sri Lanka was considerably higher than that among Sri Lankans living in Oslo, Norway. The low vitamin D status commonly observed in non-Western immigrant groups living at northern latitudes should not be regarded as normal levels for these groups. However, also in Sri Lanka we found a profound seasonal variation with the lowest levels in August and September after the Monsoon.
