In our study, participants' mean BMI was increased (over 30: 29,42 kg⁄m2 and before 30: 29,31 kg⁄m2) . For further details of physical parameters please see Table 1.
Bone mass and bone density were significantly and moderately correlated (r=0,57 and p<0,01). Bone mass was significantly, negatively correlated with vit D intake (r=-0,24 and p<0,01). BMI was weakly but significantly negatively correlated with vit D intake and level (r=-0,14 and p<0,05).
Bone density was significantly increased by sherry consumption with weak correlation (r=0,16 and p˂0,05).
BMI was significantly and weakly correlated with bone density (r=-0,26 and p<0,01), moderately and significantly correlated with body fat (r=0,67 and p<0,01). BMI was negatively correlated with body water content (r=0,63 and p<0,01) and with muscle content (r=0,28 and p<0,01).
Regarding to dietary habits, citrus fruits consumption significantly decreased bone density (r=-0,15 and p<0,05) altough correlation was very weak.
ß-CTx level, which indicates bone resorption was significantly affected by dietary habits. Breakfast cereal resulted negative correlation with ß-CTx level (r=-0,21 and p<0,01), similar negative correlation was observed with white rice (r=-0,16 and p<0,05), white fish (r=-0,16 and p<0,05), pulses (r=-0,14 and p<0,05), core crops (r=-0,15 and p<0,05). Butter consumption significantly increased ß-CTx level, the correlation was weak (r=0,14 and p<0,05).
DXA LS score and even previous DXA LS scores were negatively affected by beef consumption, the correlation was again weak (r=-0,14 and p<0,05, r=-0,19 and p<0,05, respectively). DXA LS score was significantly increased by yoghurt intake (r=0,14 and p<0,05).
Olive oil consumption leaded to significantly higher vit D level, with weak correlation (r=0,14 and p<0,05).
Interestingly, DXA LS score (r=0,19 and p<0,01), previous LS score (r=-0,2 and p<0,05) was negatively affected by olive oil consumption. Previous DXA LS score was negatively affected by dairy based pudding intake (r=-0,19 and p<0,01).
Bone density was weakly, but significantly correlated with DXA FN score (r=0,23, and p<0,01), DXA LS score (r=0,20, and p<0,01), previous DXA LS score (r=0,30, and p<0,01) and with previous DXA FN score (r=0,22, and p<0,01).
Bone mass was significantly and weakly correlated with DXA LS score (r=0,29, and p<0,01). It moderately correlated with DXA FN score (r=0,39, and p<0,01), previous DXA LS score (r=0,33, and p<0,01), previous DXA FN score (r=0,43, p<0,01).
The number of deliveries negatively affected muscle content (r=0,14, and p<0,05).
The age of last delivery did not affect vit D and ß-CTx levels (Table 2).
Our results show that in the over 30 group, the DXA FN score was significantly worsen compared to the before 30 group (r=0,16 and p<0,05). The progression (values of the DXA scores during follow-up examinations) was also worsen in the over 30 group compared to the before 30 group (r=0,14 and p<0,05) (Table 3).
The number of deliveries were significantly different between these groups ( p<0,05). In the before 30 group there was less delivery (2,01±0,68 vs 1,70±0,59) (Table 4). So the differences between groups can not be caused by the number of pregnancies.
