Vitamin D status and parathyroid hormone levels in patients with obstructive sleep apnea

What Was Tested

Researchers studied Parathyroid Hormone (PTH 1-84) in the context of sleep apnea (obstructive) in this observational study publication.

Vitamin D insufficiency and high levels of parathyroid hormone (PTH) appear to be emerging risk factors for metabolic syndrome (MS), diabetes and cardiovascular disease, conditions that occur frequently in patients with obstructive sleep apnea syndrome (OSAS).

Who Took Part

The study group was 826 patients.

By PubMed's age tags, the people studied were adults, middle-aged adults and older adults, both men and women.

The occurrence of the MS was analyzed according to the National Cholesterol Education Program Adult Treatment Panel III clinical criteria.

How the Study Was Run

Serum levels of 25(OH)D, PTH, glucose, triglycerides, cholesterol, HDL cholesterol, creatinine and uric acid were determined.

What Was Measured

Vitamin D insufficiency and high levels of parathyroid hormone (PTH) appear to be emerging risk factors for metabolic syndrome (MS), diabetes and cardiovascular disease, conditions that occur frequently in patients with obstructive sleep apnea syndrome (OSAS).

PubMed files the paper under topics including Diabetes Complications, Hypertension, Metabolic Syndrome, Parathyroid Hormone, Prevalence, Sleep Apnea, Obstructive and Spain.

What This Means in Plain Language

This is an observational study of Parathyroid Hormone (PTH 1-84) in 826 patients in people with sleep apnea (obstructive).

With several hundred people or more, it is a fairly large study for this kind of research.

The abstract goes on to report its results in about 6 sentences; this page does not restate them, so read the paper for the findings and their limits.
