Using these profiles, they identified specific features that may partially regulate the biological processes that impact mental health and metabolic conditions that appear to be related to inflammation, and may help explain the higher incidences of depression and diabetes among <abbr>NHPIs<\/abbr>. Examples of these findings include:<\/p>\n<ul>\n<li>A novel interaction between self-esteem and abundance of <em>Veillonellaceae<\/em> bacteria, where increased levels of this bacteria in the gut corresponded to a significant increase in self-esteem, with individuals with low self-esteem (a risk factor for depression) showing abnormally low levels of this bacteria.<\/li>\n<li>Shared imbalance of <em>Bacteroidetes<\/em> between diabetes and obesity, where its abundance was observed to decrease with poor glycemic control and increase with obesity.<\/li>\n<li>A significant and specific deficiency in the levels of butyrate-producing bacteria in the gut of pre- and diabetic participants, that corresponded to increased systemic inflammation.<\/li>\n<li>A novel significant association between the levels of <em>Cyanobacteria<\/em> (which produces toxins and implicated in cancer risk in <span aria-label=\"Hawaii\">Hawai&#699;i<\/span>) and poor glycemic control, with overabundance of this bacteria in the gut of diabetic participants.<\/li>\n<li>A significantly higher gut microbial diversity in obese and diabetic individuals of <abbr>NHPI<\/abbr> ancestry.
