BMI Trends for Veterans Up to 10 Years After VA Enrollment Following Military Discharge.

ABSTRACT:

Background

Obesity (body mass index [BMI]≥30kg/m²) among US adults has tripled over the past 45 years, but it is unclear how this population-level weight change has occurred.

Objective

We sought to identify distinct long-term BMI trajectories and examined associations with demographic and clinical characteristics.

Design

The design was latent trajectory modeling over 10 years of a retrospective cohort. Subgroups were identified via latent class growth mixture models, separately by sex. Weighted multinomial logistic regressions identified factors associated with subgroup membership.

Participants

Participants were a retrospective cohort of 292,331 males and 62,898 females enrolled in VA.

Main measures

The main outcome measure was 6-month average
