I would say no. This has been studied for 30 years. This was a meta-analysis study, so it used the 30 years of study before it to come up with the causation aspect of it.
Until this point, for the last 30 years of studying this, we've only been able to show that people who engage in this behaviour also engaged in that behaviour. For the first time now we have a study, which came out in 2016, that says that people who engage in this behaviour are more likely to engage in that behaviour. It's a causation rather than a correlation.
