OBJECTIVE: To evaluate whether sex differences in the associations of subclinical hypothyroidism (SH) and subclinical hyperthyroidism (SCH) with the risks of major adverse cardiovascular events (MACE) and fractures.
METHODS: The PubMed, EmBase, and Cochrane Library databases were searched for eligible studies from inception until November 2021. The relative risk (RR) ratio with the 95% confidence interval (CI) was used to identify sex differences in the associations of SH and SCH with the risks of MACE and fractures. All analyses were performed using a random-effects model.
RESULTS: Twenty-four cohort studies (in 3,480,682 patients) were selected for meta-analysis. There were no sex differences in the associations of SH and SCH with the risks of atrial fibrillation, all-cause mortality, cardiac death, coronary heart disease, heart failure, MACE, stroke, fracture. Subgroup analyses indicated a greater risk of MACE in men than in women with SH if follow-up was ≥10.0 years (RR ratio 2.44; 95% CI 1.17-5.10; P = 0.017). The risk of any fracture was greater in men than in women with SH if follow-up was <10.0 years (RR ratio 1.17; 95% CI 1.03-1.34; P = 0.017) and in studies with a high level of adjustment (RR ratio 1.16; 95% CI 1.02-1.32; P = 0.022). However, the risk of hip fracture was lower in men than in women with SH on pooling of studies with low adjustment (RR ratio 0.53; 95% CI 0.29-0.97; P = 0.039).
CONCLUSIONS: There may be sex-related differences in the risks of MACE, any fracture, and hip fracture in patients with SH.
