Rationale: Recent studies on osteoporosis have focused on dietary pattern rather than individual nutrient intake. This study aims to assess the association of bone mineral density (BMD) with Nordic diet score (NDS) characterized by high consumption of Nordic berries and fruits, whole grains, vegetables, fish, and low consumption of processed meat among elderly women.

Methods: The data are from interventional “Kuopio Osteoporosis Risk Factor and Fracture Prevention study (OSTPRE-FPS)”. At the baseline, 554 women, with mean±SD age of 67.9±1.87 and body mass index(BMI) of 28.8±4.71 kg/m², filled in 3-day food record and questionnaire on life style, disease, and medications. BMD was measured by dual energy X-ray absorptiometry in lumbar spine (L2-L4), femoral neck and total body at the baseline and year 3. In our prospective study NDS was calculated by summing the category score (0-3) of positively related foods (whole grains, vegetable, fruit, fish, low fat dairy products, total fat intake, polyunsaturated to saturated fatty acid ratio) with the reverse scores of negatively related foods (processed meat and alcohol). Association of NDS with BMD was analyzed by mixed linear model. We tested energy intake, hormone therapy(HT), calcium and vitamin D supplementation, diseases affecting BMD, mobility, time from menopause, life time smoking , BMI, age, and intervention group as covariates. In the final model significant covariates including Ca supplementation, mobility, smoking, BMI, and HT remained.

Results: All sites showed the highest BMD value in the 3^rd NDS quartile: Lumbar (NDSQ1=1.060, 2=1.090,3=1.130,4=1.110 g/cm²),femoral(NDSQ1=0.849,2=0.849,3=0.885,4=0.833 g/cm²), total (NDSQ1=1.038, 2=1.026, 3=1.067,3=1.041). Association of NDS was significant with lumbar and femoral BMD (p=0.046 and, p=0.027, respectively). but non-significant with total body BMD (p=0.089).

Conclusion: Nordic diet may be related to higher BMD in elderly women.
