Impact of lifestyle intervention on vitamin D, Adiponectin, Insulin-like growth factor 1 and Proneurotensin in overweight individuals from the Middle East

What Was Tested

This randomized controlled trial paper looks at IGF-1 LR3.

In ME immigrants at high risk of developing T2D, the researchers aimed to study the effect of a randomized culturally adapted lifestyle intervention on the levels of Vitamin D (25(OH)D), insulin-like growth factor 1 (IGF-1), Pro-neurotensin (Pro-NT) and Adiponectin.

Furthermore, the researchers aimed to study if the effect of the intervention was associated to these hormones, or if a direct effect of the intervention remained after accounting for these.

Why It Was Studied

Immigrants from the Middle East (ME) have a higher prevalence of type 2 diabetes (T2D) compared to the native-born Swedish population.

In individuals free from T2D, ME immigrants are more insulin resistant and have lower levels of adjusted insulin secretion (Disposition index, DIo) compared to Swedish-born individuals.

Who Took Part

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

In this culturally adapted randomized controlled trial of four months duration, eligible ME immigrants at high risk of developing T2D identified in the MEDIM cohort were invited to participate.

How the Study Was Run

In design terms this was a randomized study.

The participants were allocated by chance, so the IGF-1 LR3 group and the comparison group should start out alike.

The intervention group (N= 35) received a culturally adapted lifestyle intervention program consisting of seven group sessions and cooking classes.

What Was Measured

In individuals free from T2D, ME immigrants are more insulin resistant and have lower levels of adjusted insulin secretion (Disposition index, DIo) compared to Swedish-born individuals.
