Computer use and cardiovascular risk biomarkers in midlife and older adults

With increased computer usage amongst midlife and older adults, concerns are emerging with regards to the potential adverse health effects of computer use given the sedentary habits it may encourage. The current study aims to investigate the relationship between computer use and cardiovascular risk in midlife and older adults. From the National Survey of Midlife Development in the United States II: Biomarker Project (2004–2009) and the National Survey of Midlife Development in the United States (MIDUS II), 2004–2006, we examined five cardiovascular risk biomarkers—high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides, interleukin-6, and C-reactive protein—in relation to self-reported general computer use frequency and computer use at work frequency. Our results show that general computer use frequency and computer use at work frequency were not significant predictors of any of the five cardiovascular risk biomarkers—HDL cholesterol, LDL cholesterol, triglycerides, interleukin-6, and C-reactive protein. However, our exploratory analysis showed that employment status significantly moderated the relationship between general computer use frequency and LDL cholesterol. Our study highlights the importance of a more nuanced approach to understanding the health implications of computer use and sedentary behaviour in general.
