Group AB also had a negative correlation with age, although this was less pronounced: indeed, its effects were conditioned by gender, being significant only in females. The proportion of subjects with group A blood increased with age, but again this effect was significant only in females. Thus a conditioning effect of gender was evident for both A and AB groups. We have no explanations for these observations, although an association between B blood type and some aging-associated degenerative disorders, such as Parkinson\u2019s disease, has been found.<\/p><cite> <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4385082\/\">https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4385082\/<\/a> <\/cite><\/blockquote>\n\n\n\n<p>Rh negative blood has not been examined in the above study.<\/p>\n\n\n\n<p>ADDED:<\/p>\n\n\n\n<p>This is not the only European study indicating lower life expectancy in Europe for blood type B:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>To assess the observation that blood type B might be a marker for longevity, we reviewed the records and determined the ABO blood types of all patients who died in our hospital in 2004. Age was stratified by decade of death, and linear regressions were calculated by ABO percentage. ABO survival curves were compared. In 2004, 906 patients died; 35 were excluded (stillborn infants). Of the remaining 871 patients, ABO types were available for 772 (88.6%). The percentage of patients with group B blood declined with age (P &lt; .01). None of the other blood type percentages had a statistically significant increase or decrease. The group B survival curve was statistically worse than non-B groups (P \u2264 .01); there were no differences in survival among groups A, O, and AB (P =.47). In our patient population, the percentage of patients with group B blood declines with age. The survival curve in group B was worse than that in groups A, O, and AB. These findings suggest that in our patient population, blood group B is not a marker for longevity but may be a marker for earlier death.<br><\/p><cite> <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/21173130\/\">https:\/\/pubmed.ncbi.nlm.nih.gov\/21173130\/<\/a> <\/cite><\/blockquote>\n<div style=\"padding-bottom:20px; padding-top:10px;\" class=\"hupso-share-buttons\"><!-- Hupso Share Buttons - https:\/\/www.hupso.com\/share\/ --><a class=\"hupso_toolbar\" href=\"https:\/\/www.hupso.com\/share\/\"><img data-recalc-dims=\"1\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/static.hupso.com\/share\/buttons\/share-medium.png?w=640&#038;ssl=1\" style=\"border:0px; padding-top:5px; float:left;\" alt=\"Share Button\"\/><\/a><script type=\"text\/javascript\">var hupso_services_t=new Array(\"Twitter\",\"Facebook\",\"Pinterest\",\"Linkedin\");var hupso_background_t=\"#EAF4FF\";var hupso_border_t=\"#66CCFF\";var hupso_toolbar_size_t=\"medium\";var hupso_twitter_via = \"datebytype\";var hupso_image_folder_url = \"\";var hupso_twitter_via=\"datebytype\";var hupso_url_t=\"\";var hupso_title_t=\"Life expectancy and blood types: Blood type B\";<\/script><script type=\"text\/javascript\" src=\"https:\/\/static.hupso.com\/share\/js\/share_toolbar.js\"><\/script><!-- Hupso Share Buttons --><\/div>","protected":false},"excerpt":{"rendered":"<div style=\"padding-bottom:20px; padding-top:10px;\" class=\"hupso-share-buttons\"><!-- Hupso Share Buttons - https:\/\/www.hupso.com\/share\/ --><a class=\"hupso_toolbar\" href=\"https:\/\/www.hupso.com\/share\/\"><img src=\"https:\/\/static.hupso.com\/share\/buttons\/share-medium.png\" style=\"border:0px; padding-top:5px; float:left;\" alt=\"Share Button\"\/><\/a><script type=\"text\/javascript\">var hupso_services_t=new Array(\"Twitter\",\"Facebook\",\"Pinterest\",\"Linkedin\");var hupso_background_t=\"#EAF4FF\";var hupso_border_t=\"#66CCFF\";var hupso_toolbar_size_t=\"medium\";var hupso_twitter_via = \"datebytype\";var hupso_image_folder_url = \"\";var hupso_twitter_via=\"datebytype\";var hupso_url_t=\"\";var hupso_title_t=\"Life expectancy and blood types: Blood type B\";<\/script><script type=\"text\/javascript\" src=\"https:\/\/static.hupso.com\/share\/js\/share_toolbar.js\"><\/script><!-- Hupso Share Buttons --><\/div>For another study indicating longevity in blood type B, see the Japanese study on this blog.
