They stratified the blood group of 28,129 subjects according to age and gender and found that group A was statistically more represented in the male population (43.40%&nbsp;<em>vs<\/em>&nbsp;40.50%), whilst the opposite was true for group B (10.70%&nbsp;<em>vs<\/em>&nbsp;13.48%). The Authors observed that the proportion of individuals with group B declined significantly with age regardless of gender. For example, 17.62% of the individuals aged between 20 and 29 years were type B compared to only 9.05% of those aged 80\u201389 years. Some other associations were confined only to females: the prevalence of group AB declined with age, while the prevalence of group A tended to increase with age. Of note, although not statistically significant, 70% of subjects aged over 99 years had type O blood.<\/p>\n<cite>https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4614285\/<\/cite><\/blockquote>\n\n\n\n<p>Clicking on the names of the individuals who conducted the study seems to reveal Australia as the location.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><sup>1<\/sup>Department of Haematology, Institute of Clinical Pathology and Medical Research, Pathology West, Westmead Hospital, Westmead, Australia<\/p>\n<\/blockquote>\n\n\n\n<p>From same study:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>The above-noted research has logically extended to studies on the potential association of the ABO blood group with&nbsp;<em>longevity<\/em>, in an attempt to explain differences in life span among individuals with different blood groups. Prior to the report by Mengoli and Colleagues in the past issue of Blood Transfusion<sup><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4614285\/#b6-blt-13-351\">6<\/a><\/sup>, there have only been a few reports in English on a potential association between certain ABO phenotypes and longevity. Murray was the first to publish his findings in 1961 of increased prevalence of group A in 125 healthy elderly males (65\u201389 years)<sup><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4614285\/#b7-blt-13-351\">7<\/a><\/sup>. Eight years later, a study carried out on 50 inhabitants of eastern Turkey allegedly aged &gt;90 years (interestingly, one individual claimed to be 155 years old) found no correlation between the ABO system and longevity; instead the authors reported a significant difference in the prevalence of P and Lewis types in the senescent group compared to 110 controls<sup><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4614285\/#b8-blt-13-351\">8<\/a><\/sup>. In a survey of German doctors aged &gt;75 years, group O appeared to be associated with longer life expectancy<sup><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4614285\/#b9-blt-13-351\">9<\/a><\/sup>. Findings of two studies performed on centenarians were contradictory. Blood type B was observed more frequently in 269 Japanese centenarians (29.4%) than in controls (21.9%)<sup><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4614285\/#b10-blt-13-351\">10<\/a><\/sup>. By contrast, in the only study using molecular ABO typing, Vasto and Colleagues failed to demonstrate significant differences in the distribution of ABO groups between a group of 38 centenarians and healthy controls (age range, 45\u201365 years) from western Sicily<sup><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4614285\/#b11-blt-13-351\">11<\/a><\/sup>. Finally, following a review of 772 deaths in their hospital in the United States, Brecher and Hay concluded that B type, rather than being associated with longevity, was a marker of early death<sup><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4614285\/#b12-blt-13-351\">12<\/a><\/sup>.<\/p>\n<\/blockquote>\n\n\n\n<p>From SHEILAGH MURRAY, M.D. Director, Regional Transfusion Centre, Newcastle upon Tyne:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>The ABO groups and Rh genotypes are reported on 633 persons over 64 years of age.
