Introduction

Physical activity is known to significantly impact cardiometabolic health. Accelerometer data, as a measure of physical activity, can be used to objectively identify a disparity in movement movement discordance between healthy and unhealthy adults. The purpose of this study was to examine the Movement Discordance between healthy and unhealthy adults in a large US population sample.

Methods

Demographic, health and accelerometer data from the National Health and Nutrition Examination Study NHANES 2003–2004 and 2005–2006 cohorts were used for this study. Participants were classified as either having a -normal- or -abnormal- value for each cardiometabolic health parameter examined, based on published criteria. Linear regression analyses were performed to determine significance of each abnormal health parameter risk factor in its unique effect on the accelerometer counts, controlling for age and gender. Average accelerometer counts per minute cpm by gender and age categories were estimated separately for the groups of normal and abnormal cardiometabolic risk.

Results

Average cpm for those with healthy levels of each individual cardiometabolic health parameter range from 296 cpm for C reactive protein to 337 cpm for waist circumference, while average cpm for those with abnormal levels of each individual cardiometabolic health parameter range from 216 cpm for insulin to 291 cpm for LDL-cholesterol. After controlling for age and gender, waist circumference, HbA1c, Insulin, Homocysteine, and HDL-Cholesterol were the cardiometabolic health parameters that showed significant, unique and independent effects on cpm. Overall, individuals who have abnormal values for all significant cardiometabolic health parameters -unhealthy- averaged 267 cpm SE = 15 cpm, while the healthy sample of this study averaged 428 cpm SE = 10 cpm. The difference in cpm between the unhealthy and healthy groups is similar between males and females. Further, for both males and females, the cpm gap between unhealthy and healthy is largest in the 30s males: 183 cpm; females 144 cpm and lessens as age increases, with the lowest gap seen in those 80+ years males, 81 cpm; females, 85 cpm.

Conclusion

This Movement Discordance between healthy and unhealthy adults represents a gap in movement that needs to be closed to improve the health of individuals with, or at risk for cardiometabolic disease.
