Abstract

To identify the relationship between subclinical thyroid dysfunction and the risk of fracture, we conducted a meta-analysis of prospective cohort studies. Results showed that subclinical hyperthyroidism is associated with an increased risk of fracture, especially in elder. There are conflicting data on the association between subclinical thyroid dysfunction and the risk of fracture. This study is aimed at providing a summary of prospective evidence of the relationship between subclinical thyroid dysfunction and the risk of fracture. We systematically searched the MEDLINE, EMBASE, and the Chinese Biomedical literature database (CBM) from 1974 to August 2014 to identify prospective cohort studies which have studied the risk of fracture in patients with subclinical thyroid dysfunction. Various fractures were reported as the sole outcome. Five population-based cohort studies including 314,146 participants with relationship of endogenous or exogenous subclinical thyroid dysfunction or euthyroidism and fractures were identified as eligible for the meta-analysis. In an unadjusted model, the relative risk (RR) of subclinical hypothyroidism for fracture was 1.30 (CI 1.08-1.56). Risk estimates were lower in a multivariable-adjusted model (RR = 1.20, CI 0.70-2.04) and when higher quality studies (RR = 0.95, CI 0.58-1.57) were analyzed. For subclinical hyperthyroidism, the RR was 1.52 (CI 1.33-1.73) in unadjusted model and 1.25 (CI 1.11-1.41) in a multivariable-adjusted model. An analysis of higher quality studies revealed a RR 1.18 (CI 1.07-1.29). Subgroup analysis indicated that the RR for risk of fracture was higher in the endogenous group than the exogenous group, taking thyroid-altering medicine in subclinical hyperthyroidism. Similar finding was also demonstrated in subclinical hypothyroidism. Despite heterogeneity across the studies, data suggest that subclinical hyperthyroidism is associated with an increased risk of fracture in the population older than 60 years. No evidence could prove a definite association between subclinical hypothyroidism and the risk of fracture yet.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 1. 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 04 August 2015.
All research outputs
#20,284,384
of 22,818,766 outputs
Outputs from Osteoporosis International
#2,964
of 3,609 outputs
Outputs of similar age
#219,839
of 263,145 outputs
Outputs of similar age from Osteoporosis International
#57
of 81 outputs
Altmetric has tracked 22,818,766 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,609 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 7.6. This one is in the 1st percentile – i.e., 1% 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 263,145 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 81 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
