The Checkup blogger Rob Stein writes: “About 23 percent of those who drank one or no cans of soda a week carried a gun or knife, and 15 percent had perpetrated violence toward a partner. In comparison, among those who consumed 14 or more cans a week, 43 percent carried a gun or knife and 27 percent had been violent toward a partner, the researchers found. Similarly, violence towards peers rose from 35 percent to 58 percent while violence towards siblings rose from 25.4 percent to 43 percent.”
Researchers Sara J. Solnick of the University of Vermont and David Hemenway of the Harvard School of Public Health in Boston also found that “those who drank five or more cans of non-diet soft drinks every week were significantly more likely to have also consumed alcohol and smoked cigarettes at least once in the previous month,” Stein says.
Solnick and Hemenway analyzed data collected from 1,878 14- to 18-year-olds in grades nine through 12 in 22 public schools in 2008.
