Abstract

Background

Osteoporosis is a bone disease that combines both a decrease in bone density and its internal architecture changes. Nutrition is one of the major determinants of osteoporosis.

Aim

The purpose of our study was to identify nutritional risk factors of osteoporosis of two groups of osteoporotic women and witnesses.

Methods

We conducted a comparative cross-sectional study including 60 postmenopausal women and screening for osteoporosis by a bone densitometry, recruited the outpatient service of Rheumatology of the Institute KASSAB.

Results

We have identified excessive supply of saturated fatty acids (SFA) in the osteoporotic compared with controls (13.27% vs 10.23%, p = 0.002) and an inadequate intake of monounsaturated fatty acids (MUFA) (12.6% vs 16.16%, p = 0.012).

A low calcium intake is another factor of risk of osteoporosis (574.27 ± 336.9 mg/day vs 782.45 ± 340.54 mg/day; p = 0.021). This is explained by the low consumption of milk and milk products objectified in the osteoporotic group (p = 0.001). We also found a negative relationship between inadequate intakes of potassium and osteoporosis (2241.55 ± 1049.85 mg/day vs 2988.17 ± 1146.52 mg/day; p = 0.011). This may be due to the low consumption in fruit and vegetables, sources of potassium, found in the osteoporotic group (p = 0.003).

We found a significant increase in the consumption of the VVPO group in the osteoporotic toward women witness (2.23 ± 0.99 number of times/day vs 1.67 ± 0.76 number of times/day; p = 0.019).

A high consumption of coffee appears also as a risk factor since the osteoporotic group consume almost twice than controls (p = 0.002).

Conclusion

Nutritional risk factors of osteoporosis are all the most important that they are editable and can take their place in a prevention of public health policy.
