Abstract

Introduction

Chronic conditions are costly and major causes of death and disability. Addressing conditions earlier in adulthood can slow disease progression and improve well-being across the lifespan. We estimated, by life stage, 10-year trends among US adults in the prevalence of 1 or more chronic conditions, multiple chronic conditions (MCC; ≥2 conditions), and 12 selected chronic conditions.

Methods

We analyzed data from the 2013-2023 (odd years) Behavioral Risk Factor Surveillance System (N = 2,673,529). We estimated the prevalence of 1 or more conditions, MCC, and each of 12 conditions, by life stage: young (18-34 y), midlife (35-64 y), and older (≥65 y) adults. We used polynomial contrasts to analyze 10-year trends.
