| Abstract |
Dietary magnesium intake has been related to osteoporosis and risk of fractures in earlier studies; however, findings were conflicting. This meta-analysis indicated that high magnesium intake was not associated with increased risk of fracture; however, a positive marginally significant correlation was found between magnesium intake and bone mineral density (BMD) in total hip as well as in femoral neck. Although there is some evidence on the association between magnesium intake, BMD and fractures, no previous study has summarized findings in this regard. We aimed to systematically review the current evidence on this association and to perform a meta-analysis of observational studies. We searched MEDLINE, Scopus, EMBASE and Google Scholar up to January 2015 for studies that examined the relationship between magnesium intake and BMD or fracture. Studies that had reported correlation coefficients between magnesium intake and BMD or those that reported odds ratios (ORs) or relative risks (RRs) for risk of fracture in different sites were included. In total, 12 studies were included in the meta-analysis. We found that high intakes of magnesium were not significantly associated with risk of total hip fracture (summary effect size 1.92; 95 % CI 0.81, 4.55) or total fractures (1.01; 0.94-1.07). Combining four effect sizes, a positive marginally significant correlation was observed between magnesium intake and total BMD (pooled r 0.16; 95 % CI 0.001, 032). Based on nine effect sizes, we found a marginally significant association between magnesium intake and femoral neck BMD (0.14; 0.001, 0.28). However, no significant correlation was found between magnesium intake and BMD in lumbar spine (0.09; -0.01, 0.19). We found that high intakes of magnesium were not associated with increased risk of hip and total fractures. There was a positive marginally significant correlation between magnesium intake and BMD in femoral neck and total hip. No significant correlations were observed between magnesium intake and BMD in lumbar spine. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 19 July 2018.
All research outputs
#14,766,324
of 24,752,948 outputs
Outputs from Osteoporosis International
#2,148
of 3,817 outputs
Outputs of similar age
#140,052
of 288,697 outputs
Outputs of similar age from Osteoporosis International
#40
of 97 outputs
Altmetric has tracked 24,752,948 research outputs across all sources so far. This one is in the 39th percentile – i.e., 39% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,817 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.0. This one is in the 42nd percentile – i.e., 42% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 288,697 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 49th percentile – i.e., 49% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 97 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 54% of its contemporaries.
