Objective: It is estimated that 41 million American adults 18 and older experience poor physical or mental health which limits their ability to engage in their daily activities. The objective of this study was to assess the prevalence of and factors associated with ≥14activity limitation days (ALD) due to poor physical or mental health as self-reported by persons aged 18 years and over in the United States (U.S).
Methods: Using the 2012 Behavioral Risk Factors Surveillance System (BRFSS), persons over the age of 18 in the U.S. were examined to assess the prevalence of and factors associated with ≥ 14ALD due to poor physical or mental health. The BRFSS is administered on a continuous basis by telephone using random-digit dial sampling methods. A clustering sample design was used to account for differences in the probability of selection and non-response in order to accurately derive US and state-based population estimates. The design consists of a probability sample of all households with telephones in the state. Analyses were conducted using SAS 9.2.
Results: Of the 104,257 participants included in the analyses, 40% reported having ≥14 ALD due to poor physical or mental health. After adjusting for demographic and socioeconomic factors, males (AOR1.17, 95% CI: 1.14-1.21), those with high school or less education (AOR: 1.42, 95% CI: 1.37-1.21), those who were separated (AOR: 1.23; 95% CI=1.14-1.32), divorced (AOR: 1.10; 95% CI=1.06-1.15), those from the Southern Black Belt States (AOR1.14, 95% CI: 1.10-1.20), and those from the remainder of the Southern region of the U.S. (AOR1.14, 95% CI: 1.08-1.21) were significantly more likely to report ≥14ALD due to poor physical or mental health.
Conclusion: The prevalence of ≥14ALD due to poor physical or mental health among the study population was associated with sociodemographic and region of residence factors. These findings highlight the need for prevention strategies specifically for populations who might be more at risk for ALD due to social determinants of health.
