Lack of pattern of birth in patients with bulimia nervosa

“…This result is consistent with the findings of other authors . Only Brewerton et al were able to find significant differences across seasons between patients with and without BN. These differences could be an artifact because of the small sample size in the BN group ( n = 85).…”

“…In a recent work, Brewerton, et al concluded that there were significant differences across seasons between patients with ( n = 85) and without ( n = 2898) BN among a nonclinical sample in the United States of America. Fall was the season with the highest relative number of births.…”

Season of birth and subclinical psychosis: Systematic review and meta-analysis of new and existing data

“…Season of birth (SOB) has been shown to modify risk for several health outcomes, including a number of neuropsychiatric disorders (Brewerton, Dansky, O'Neil, & Kilpatrick, 2012;Cheng et al, 2013;Davies, Welham, Chant, Torrey, & McGrath, 2003;Disanto et al, 2012;Dome, Kapitany, Ignits, & Rihmer, 2010). In effect, there is evidence indicating that seasonality influences fetal growth and development (Currie & Schwandt, 2013;Flouris, Spiropoulos, Sakellariou, & Koutedakis, 2009;Strand, Barnett, & Tong, 2011;Watson & McDonald, 2007), which bears significance for psychiatric research.…”

Season of birth bias and anorexia nervosa: Results from an international collaboration

“…Examples include: novelty seeking, 1 chess expertise, 2 smoking, 3 schizophrenia, 4,5 obesity, 6 and bulimia nervosa. 7 For females with AN, several studies report a season of birth bias with more births during the first 6 months of the year, 8 particularly in the spring months in Europe. 9,10 These findings are strengthened by a pooled meta-analyses of some of the UK samples 11 and a narrative review of the field.…”
