Associations of BMI, sleep quality, and sleep duration trajectories with new-onset diabetes mellitus in the elderly.

ABSTRACT:

Objective

Our objective was to investigate the relationships between BMI, sleep quality, and sleep duration trajectories and new-onset diabetes mellitus (NODM) in the elderly.

Methods

We analyzed 2648 diabetes-free participants aged ≥60 years from the Chinese Longitudinal Healthy Longevity Survey (CLHLS) in 2014. Using Cox proportional hazards models, we examined the associations of BMI, self-reported sleep quality, and sleep duration trajectories (categorized as persistent short, persistent normal, persistent long, low-increasing, normal-decreasing, normal-increasing, and long-decreasing) with NODM risk over 4 years. Diabetes diagnosis was self-reported.

Results

Over 4 years, 94 participants developed NODM. Obesity was associated with the highest risk (adjusted hazar
