Type A insulin resistance typically occurs in younger patients, while type B insulin resistance occurs more often in older women. Women with polycystic ovary syndrome (PCOS) usually present in their mid-20s. Many rare disorders of insulin resistance present in early life (eg, leprechaunism [first year of life], lipodystrophic states [ages 6-9 y until early puberty]).

The strongest relationship between insulin resistance and cardiovascular risk factors is observed in middle-aged persons rather than in older individuals, although cardiovascular morbidity and mortality increase with age.

Despite the growing obesity epidemic and insulin resistance in children, no clear diagnostic criteria and surrogate markers have been identified. An international consensus group recommended against screening for insulin resistance in children based on existing methodology and criteria. [40]
