Differing definition-based prevalence of metabolic syndrome in the women of Oman family study: a function of multiparity.

Objective: The aim of this study was to investigate causes of the prevalence of the metabolic syndrome in multiparous Omani Arab women using the International Diabetes Federation definition (IDF).

Research Design And Methods: Of 392 married women (mean age 40 years), 354 (90%) were multiparous with an average parity of 8. They were divided into four parity groups: Para 0, Para 1-3, Para 4-6, and Para >6.

Heritability of determinants of the metabolic syndrome among healthy Arabs of the Oman family study.

The metabolic syndrome, as defined by the International Diabetes Federation, was investigated in five large, extended, highly consanguineous, healthy Omani Arab families of a total of 1277 individuals. Heritability (h2) of the phenotypic abnormalities that make up the syndrome and other related traits was estimated by variance decomposition method using SOLAR software. The overall prevalence of the syndrome was 23%.
