This hypothesis, however, does not explain some other irregularities in the month of birth distribution in contrast to the seasonal preovulatory <jats:italic>o<\/jats:italic>verripeness ovopathy (SPrOO) and seasonal optimally ripened oocytes (SOptRO) hypotheses.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>The month of birth distribution of 408 patients with EDs from Southeast England and of 199 patients from Australia has been reassessed in relation to previously determined high\u2010risk and low\u2010risk months based on a priori knowledge from mammals and on the physiologic birth peaks and troughs in humans at population level. The differences between high\u2010risk and low\u2010risk months were assessed by conventional chi\u2010square analyses and by relative risks (RRs) with 95% confidence intervals (CI).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In England, fewer AN patients (<jats:italic>n<\/jats:italic> = 259) were born at the peaks of the total birth pattern, that is, during the 2 low\u2010risk months, and more were born during the transitional stages, that is, during the remaining 10 high\u2010risk months (<jats:italic>p<\/jats:italic> = .004; RR = 1.66 [95% CI = 1.13\u20132.41]). After the addition of 149 other ED patients (<jats:italic>n<\/jats:italic> = 408), this result remained (<jats:italic>p<\/jats:italic> = .005; RR = 1.47 [95% CI = 1.10\u20131.97]). Similar results were found in 199 ED patients from Australia (<jats:italic>p<\/jats:italic> = .009; RR =1.70 [95% CI = 1.09\u20132.64]).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>ED patients appear to be more frequently conceived during the transitional stages of the ovulatory pattern due to SPrOO and less frequently at the ovulatory peaks due to SOptRO. The pathophysiologic processes of oocyte maturation in estrous animals and the circumstantial evidence of similar phenomena in humans are more appropriate to explain these coincidences than the temperature at conception hypothesis. \u00a9 2005 by Wiley Periodicals, Inc.<\/jats:p><\/jats:sec>","DOI":"10.1002\/eat.20173","type":"journal-article","created":{"date-parts":[[2005,10,7]],"date-time":"2005-10-07T02:16:29Z","timestamp":1128651389000},"page":"236-243","source":"Crossref","is-referenced-by-count":9,"title":["Seasonally bound ovopathy versus \u201ctemperature at conception\u201d as cause for anorexia nervosa and other eating disorders"],"prefix":"10.1002","volume":"38","author":[{"given":"Piet Hein","family":"Jongbloet","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hans M.M.","family":"Groenewoud","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nel","family":"Roeleveld","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,10,6]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00339562"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/1098-108X(199111)10:6<631::AID-EAT2260100603>3.0.CO;2-4"},{"key":"e_1_2_1_4_1","unstructured":"Birth Statistics England and Wales: Office for National Statistics London."},{"key":"e_1_2_1_5_1","unstructured":"Birth Statistics Australia: Central Office Australian Bureau of Statistics Camberra."},{"key":"e_1_2_1_6_1","first-page":"339","volume-title":"Principles and practice of obstetrics and perinatology","author":"Butcher R.L.","year":"1981"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1001\/archpsyc.56.7.634"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.1069"},{"key":"e_1_2_1_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(03)12378-1"},{"key":"e_1_2_1_10_1","doi-asserted-by":"publisher","DOI":"10.1095\/biolreprod20.3.567"},{"key":"e_1_2_1_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/0140-6736(93)90768-C"},{"key":"e_1_2_1_12_1","first-page":"105","volume-title":"Social and biological effects on perinatal mortality III, perinatal analyses","author":"Golding J.","year":"1990"},{"key":"e_1_2_1_13_1","first-page":"300","volume-title":"International symposium, Seattle, 1973, aging gametes.
