How weight change is modelled in population studies can affect research findings: empirical results from a large-scale cohort study.

ABSTRACT:

Objectives

To investigate how results of the association between education and weight change vary when weight change is defined and modelled in different ways.

Design

Longitudinal cohort study.

Participants

60 404 men and women participating in the Social, Environmental and Economic Factors (SEEF) subcomponent of the 45 and Up Study-a population-based cohort study of people aged 45 years or older, residing in New South Wales, Australia.

Weight change was modelled in four differ
