Abstract
Background: Little research has been done on the prospective associations between television viewing and cardiometabolic risk factor profiles and obesity in young adults. Additionally, individuals with high levels of hostility may be more susceptible to the influence of television viewing on cardiometabolic risk factor profiles.
Objective: This study aimed to examine whether TV viewing is predictive of adverse cardiometabolic risk factor profiles (waist circumference, HOMA insulin resistance, fasting triglycerides, HDL-cholesterol, systolic blood pressure, and clustered cardiometabolic risk score) from young to middle adulthood in the U.S. adults. We also examined whether hostility personality trait modifies the association between TV viewing and cardiometabolic risk factor profiles.
Methods: There were a total of 3,269 participants in a prospective study of Black and White adults aged 23 to 35 at examination year 5 in 1990/1. Cross-lagged panel models were analyzed at three 5-year time periods to test whether TV viewing predicts adverse cardiometabolic risk factor profiles.
Results: Individuals who watched more TV were more likely to report adverse cardiometabolic risk factor profiles in the following 5 years. The prospective association between TV viewing and obesity was observed in young adulthood but not in middle adulthood. The cross-lagged effects of TV viewing on clustered cardiometabolic risk score were significant in the high hostility group but not in the low hostility group.
Conclusion: These findings suggest that TV viewing is positively associated with adverse cardiometabolic risk factor profiles and that this association is modified by hostility.
Public Health Significance: TV viewing and cardiometabolic risk are highly prevalent in our society. As such, even a modest association between the exposure and outcomes could have high public health significance. Our data suggest that reduction in TV viewing time, especially for people who reported high viewing time and with a propensity towards a hostile disposition, could reduce cardiometabolic risk.
