When a study describes a finding as 'significantly associated,' it usually merely means that the study result can be assumed to not be due to a mere anomaly in the study data with a confidence of 95 % (the commonly used p-value of 0.05). This phrasing doesn't say anything about the effect size and its practical importance.
What is the effect size in the given study? I'm not able to find it.
The larger the sample size of a study, the more capable it becomes at identifying even weak associations between variables as "statistically significant".
The effect size might be tiny. I don't see the point of discussing these studies (and letting them influence your lifestyle) if the effect size is not part of the discussion.
The effect size should be front and center in summaries of scientific studies. I wish this was an enforced norm.
