Recent studies suggest that female patients diagnosed with anxiety and depression carry more genetic risks related to attention-deficit hyperactivity disorder (ADHD) compared with affected males.<\/jats:p>\n\t  <\/jats:sec>\n\t  <jats:sec id=\"S2056472420000472_sec_a2\" sec-type=\"other\">\n\t    <jats:title>Aims<\/jats:title>\n\t    <jats:p>In this register-based study, we aimed to test whether female patients who received clinical diagnoses of anxiety, depressive, bipolar and eating disorders are at higher familial risk for ADHD and other neurodevelopmental disorders, compared with diagnosed male patients.<\/jats:p>\n\t  <\/jats:sec>\n\t  <jats:sec id=\"S2056472420000472_sec_a3\" sec-type=\"methods\">\n\t    <jats:title>Method<\/jats:title>\n\t    <jats:p>We analysed data from a record-linkage of several Swedish national registers, including 151 025 sibling pairs from 103 941 unique index individuals diagnosed with anxiety, depressive, bipolar or eating disorders, as well as data from 646 948 cousin pairs. We compared the likelihood of having a relative diagnosed with ADHD\/neurodevelopmental disorders in index males and females.<\/jats:p>\n\t  <\/jats:sec>\n\t  <jats:sec id=\"S2056472420000472_sec_a4\" sec-type=\"results\">\n\t    <jats:title>Results<\/jats:title>\n\t    <jats:p>Female patients with anxiety disorders were more likely than affected males to have a brother with ADHD (odd ratio (OR) = 1.13, 95% CI 1.05\u20131.22). Results for broader neurodevelopmental disorders were similar and were driven by ADHD diagnoses. Follow-up analyses revealed similar point estimates for several categories of anxiety disorders, with the strongest effect observed for agoraphobia (OR = 1.64, 95% CI 1.12\u20132.39). No significant associations were found in individuals with depressive, bipolar or eating disorders, or in cousins.<\/jats:p>\n\t  <\/jats:sec>\n\t  <jats:sec id=\"S2056472420000472_sec_a5\" sec-type=\"conclusions\">\n\t    <jats:title>Conclusions<\/jats:title>\n\t    <jats:p>These results provide modest support for the possibility that familial\/genetic risks for ADHD may show gender-specific phenotypic expression. Alternatively, there could be gender-specific biases in diagnoses of anxiety and ADHD. These factors could play a small role in the observed gender differences in prevalence of ADHD and anxiety.<\/jats:p>\n\t  <\/jats:sec>","DOI":"10.1192\/bjo.2020.47","type":"journal-article","created":{"date-parts":[[2020,6,18]],"date-time":"2020-06-18T07:11:52Z","timestamp":1592464312000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":5,"title":["Investigating gender-specific effects of familial risk for attention-deficit hyperactivity disorder and other neurodevelopmental disorders in the Swedish population"],"prefix":"10.1192","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8911-3479","authenticated-orcid":false,"given":"Joanna","family":"Martin","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura","family":"Ghirardi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qi","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Catharina A.","family":"Hartman","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mina A.","family":"Rosenqvist","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark J.","family":"Taylor","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andreas","family":"Birgeg\u00e5rd","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Catarina","family":"Almqvist","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul","family":"Lichtenstein","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Henrik","family":"Larsson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"170","published-online":{"date-parts":[[2020,6,18]]},"reference":[{"key":"S2056472420000472_ref27","doi-asserted-by":"publisher","DOI":"10.1038\/s41380-018-0070-0"},{"key":"S2056472420000472_ref26","doi-asserted-by":"publisher","DOI":"10.1016\/j.bpsc.2017.11.013"},{"key":"S2056472420000472_ref23","doi-asserted-by":"publisher","DOI":"10.1016\/j.biopsych.2009.08.010"},{"key":"S2056472420000472_ref9","doi-asserted-by":"publisher","DOI":"10.1017\/S0033291717003440"},{"key":"S2056472420000472_ref7","doi-asserted-by":"publisher","DOI":"10.3109\/09540261.2010.514601"},{"key":"S2056472420000472_ref6","doi-asserted-by":"publisher","DOI":"10.1001\/jamapsychiatry.2014.16"},{"key":"S2056472420000472_ref1","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2008-1770"},{"key":"S2056472420000472_ref8","doi-asserted-by":"publisher","DOI":"10.1038\/s41380-017-0010-4"},{"key":"S2056472420000472_ref28","doi-asserted-by":"publisher","DOI":"10.1007\/s11920-008-0067-5"},{"key":"S2056472420000472_ref21","doi-asserted-by":"publisher","DOI":"10.1016\/j.biopsych.2017.11.014"},{"key":"S2056472420000472_ref2","doi-asserted-by":"publisher","DOI":"10.1007\/s10803-013-1849-0"},{"key":"S2056472420000472_ref4","doi-asserted-by":"publisher","DOI":"10.1001\/jama.1996.03540040037030"},{"key":"S2056472420000472_ref10","doi-asserted-by":"publisher","DOI":"10.1111\/jcpp.12874"},{"key":"S2056472420000472_ref11","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.b.32685"},{"key":"S2056472420000472_ref29","doi-asserted-by":"publisher","DOI":"10.1007\/s00787-018-1211-3"},{"key":"S2056472420000472_ref5","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpsychires.2009.04.003"},{"key":"S2056472420000472_ref12","doi-asserted-by":"publisher","DOI":"10.1007\/s10654-009-9350-y"},{"key":"S2056472420000472_ref25","doi-asserted-by":"publisher","DOI":"10.1001\/jamapsychiatry.2019.0566"},{"key":"S2056472420000472_ref3","doi-asserted-by":"publisher","DOI":"10.1038\/nrdp.2017.24"},{"key":"S2056472420000472_ref14","doi-asserted-by":"publisher","DOI":"10.1007\/s10654-016-0117-y"},{"key":"S2056472420000472_ref19","volume-title":"The ICD-9 Classification of Mental and Behavioural Disorders.
