Investigating the associations of glycemic load and glycemic index with lung cancer risk in the Southern Community Cohort Study.

ABSTRACT:

Purpose

Diets with a high glycemic load (GL) or glycemic index (GI) may increase cancer risk. Findings from prior studies on the relationship between GL, GI, and lung cancer risk are inconsistent. We investigated this relationship in a large prospective cohort.

Methods

We analyzed data from the Southern Community Cohort Study, a prospective cohort that includes diverse racial groups predominantly low-income adults aged 40-79 in 12 southeastern states of the USA. We estimated dietary GL and GI values using data collected from food frequency questionnaires at baseline. Dietary GL and GI were energy adjusted by residual method and categorized into sex-specific quintiles. Cox proportional hazard regression was used to assess the associations between dietary GL, GI, and lung canc
