Oral microbiota dysbiosis and altered salivary cortisol levels have been linked to depression and anxiety. Given that bacterial transmission can occur between spouses, this study aimed to investigate whether the transmission of oral microbiota between newlywed couples mediates symptoms of depression and anxiety.
Hm, skimming the abstract it sounds like their data shows couples got more similar in both depression levels and oral bacteria levels, but they didn’t really control for the oral bacteria, so I don’t see how this proves a causal link between the two. Just that they happen to both get shared after people live together. Seems more like correlation.
