Abstract
BACKGROUND AND OBJECTIVE: To assess the prevalence of hypertension, diabetes, and dyslipidaemia in subjects with subclinical hypothyroidism (SH) in comparison with an age- and sex-matched control group. PATIENTS AND METHODS: Case-control study with 240 subjects with SH and 480 controls carried out on patients aged 35-75 years admitted to a Primary Care Centre. The prevalence of hypertension, diabetes and dyslipidaemia, as well as blood pressure, plasma glucose, and lipid profilses, were evaluated in both groups. RESULTS: No differences were observed neither in the prevalence of hypertension (34.2% vs. 29.6%) or diabetes (12.1% vs. 10%) nor in mean values of blood pressure or plasma fasting glucose. Subjects with SH had an increased prevalence of lipid abnormalities (72.1% vs. 57.7%; P<.001), and increased mean values of total cholesterol (205±34 vs. 193±35mg/dL; P<.001), compared to the control group. CONCLUSION: Patients with SH have an increased prevalence of lipid abnormalities. This can be responsible for an increased cardiovascular risk in such patients.
