Is self-reported physical functioning associated with incident cardiometabolic abnormalities or the metabolic syndrome?

Abstract

Background: Physical functioning may be an important pre-clinical marker of chronic disease, used as a tool to identify patients at risk for future cardiometabolic abnormalities. This study evaluated if self-reported physical functioning was associated with the development of cardiometabolic abnormalities or their clustering (metabolic syndrome) over time.

Methods: Participants (n = 2,254) from the Study of Women's Health Across the Nation who reported physical functioning on the Short Form health survey and had a metabolic syndrome assessment (elevated fasting glucose, blood pressure, triglycerides and waist circumference; reduced HDL cholesterol) in 2000 were included. Discrete survival analysis was used to assess the 10-year risk of developing metabolic syndrome or a syndrome component through 2010.

Results: At baseline, the prevalence of metabolic syndrome was 22.0%. Women with substantial limitations (OR = 1.60; 95% CI: 1.12, 2.29) in physical functioning were significantly more likely to develop the metabolic syndrome compared with women reporting no limitations. Self-reported physical functioning was significantly associated with incident hypertension and increased waist circumference.

Conclusions: Simple screening tools for cardiometabolic risk in clinical settings are needed. Self-reported physical functioning assessments are simple tools that may allow healthcare providers to more accurately predict the course of chronic conditions.
