These researchers focused on the influence of climate and social integration, in regards to suicide rates categorized by gender. Their data suggest that both genders showed a "bimodal distribution of suicides and the sexes, but did not differ significantly from each other (x@=l2.29, d.f.=ll, P>0.30)". The authors hypothesized that the high summer peaks in suicide deaths are the result of an ultimately disappointed hope amongst the emotionally discomforted that winter might bring an end to the "social isolation and depression brought about by the cold weather". In contrast to these findings, some studies indicate that males have only one peak of suicide during the spring and early summer while women show two peaks of suicide throughout the year, during the spring and fall: " The seasonal distribution of suicides among the 117 males was similar and showed a significant seasonality: spring and summer peaks (33 and 29%, respectively) and fall–winter lows (18% and 20%, respectively, χ2=7.684, d.f.=3, P=0.053)".
