Ethnic variations in sedentary behavior and marijuana use among U.S. adults: A cross-sectional analysis

The link between sedentary behavior and substance use is drawing increased attention, especially as marijuana use becomes more prevalent in the U.S. studies suggest that excessive sedentary behavior negatively impacts health, and this research aims to explore its relationship with marijuana use to better understand its potential health implications. This cross-sectional study analyzed data from 7122 participants in the NHANES 2007 to 2012, focusing on U.S. adults with complete health and lifestyle data. Logistic regression and interaction effects analysis were used to examine the relationship between sitting time and marijuana use, controlling for confounders. Participants were categorized into 4 sitting time groups: <4 hours, 4 to 6 hours, 6 to 8 hours, >8 hours. A negative association was found between sitting time and marijuana use, with the OR for the 4 to 6 hours group at 0.91 (95% CI: 0.78-1.06, P = .227) and the 6 to 8 hours group at 0.78 (95% CI: 0.65-0.92, P = .004). Subgroup analysis showed a 48% lower risk of marijuana use in the 6 to 8 hours sitting group among Hispanic subgroups, with a 40% reduction compared to the >8 hours group. The study indicates that longer sitting times are associated with a lower likelihood of marijuana use among U.S. adults, with significant ethnic variations. Further research is needed to elucidate the relationship between sitting time and marijuana use risk. This study provides empirical data to support public health interventions targeting sedentary behavior and substance use.
