Long-term effects of a ten-year osteoporosis intervention program in a Swedish population-A cross-sectional study

•The effect of community-based osteoporosis intervention seems modest in the long run.•Elderly women were compliant with fall prevention advice using spikes in winter.•An osteoporotic calcaneal T-score may imply increased risk for fracture.•Moderate/high physical activity was positively associated with calcaneal BMD in men.•Brisk walks in the summer were positively associated with calcaneal BMD in women.

The aim of the study was to explore long-term effects seven years after the completion of a ten-year community-based osteoporosis intervention program in Vadstena, Sweden. The association between calcaneal bone mineral density and several life style factors, and the impact of risk factors for sustaining a fracture after the age of 50 were also studied. Previous participants in the intervention group, and matched subjects were invited to calcaneal bone mass measurement by a portable device including the dual X-ray and laser (DXL) technology by Calscan, and to complete a questionnaire in 2006. A total of 417 persons (63% of those invited) in the intervention (I) group, and 120 persons (47% of those invited) in the control (C) group participated. Mean age was 63 years (37-94 years). There was somewhat more knowledge of osteoporosis in the I-group (M = 18) than in the C-group (M = 17) (p < 0.05), and more use of shoe/cane spikes in elderly women in the I-group (67%) than in the C-group (40.5%). The fully adjusted model of logistic regression showed that participants with an osteoporotic DXL T-score (≤− 2.5) had a 3-fold increased risk (95%CI 1.48-6.89) of having a history of a self-reported fracture after the age of fifty compared to women with a calcaneal T-score >− 2.5. The long-term effects of a ten-year, community-based, osteoporosis intervention program on knowledge and behavior were modest seven years after its completion.
