Summary of "Diet Quality Indices and Risk of Type 2 Diabetes: The Singapore Chinese Health Study."

We aimed to test whether predefined dietary patterns inversely relating to risk of type 2 diabetes (T2D) in Western populations were similarly associated with lower T2D risk in an Asian population. We included 45,411 middle aged and older participants of the Singapore Chinese Health Study free of diabetes, cancer or cardiovascular disease at baseline (1993-1998). Participants were followed up for T2D diagnosis through 2010. Dietary information was collected using a validated food frequency questionnaire. Dietary pattern scores were calculated for the alternate Mediterranean diet, alternative Healthy Eating Index-2010, Dietary Approaches to Stop Hypertension diet, an overall plant-based diet index, and a healthful plant-based diet index. During a median 11.2 years of follow-up, 5,207 incident cases of T2D occurred. After the adjustment for multiple potential confounders, the 5 dietary pattern scores were significantly associated with 16% (for alternate Mediterranean diet) to 29% (for Dietary Approaches to Stop Hypertension diet) lower risk of T2D when comparing the highest with the lowest score quintiles (all P for trend <0.001). These associations did not vary substantially by baseline age, sex, body mass index or hypertension status, but were limited to non-smokers (P for interaction <0.001 for alternate Mediterranean diet and 0.03 for alternative Healthy Eating Index-2010). Adherence to a high-quality diet, as reflected by several predefined diet quality indices derived in Western populations, was significantly associated with lower risk of T2D in an Asian population.

Medical and Biotech [MESH] Definitions

The time period before the development of symptomatic diabetes. For example, certain risk factors can be observed in subjects who subsequently develop INSULIN RESISTANCE as in type 2 diabetes (DIABETES MELLITUS, TYPE 2).

A diet prescribed in the treatment of diabetes mellitus, usually limited in the amount of sugar or readily available carbohydrate. (Dorland, 27th ed)

A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.

An approach to nutrition based on whole cereal grains, beans, cooked vegetables and the Chinese YIN-YANG principle. It advocates a diet consisting of organic and locally grown foods, seasonal vegetables, complex carbohydrates, and fewer fats, sugars, and chemically processed foods.

The use of severity-of-illness measures, such as age, to estimate the risk (measurable or predictable chance of loss, injury or death) to which a patient is subject before receiving some health care intervention. This adjustment allows comparison of performance and quality across organizations, practitioners, and communities. (from JCAHO, Lexikon, 1994)
