To evaluate the relationship between stressful life events and the ons
et of secondary amenorrhoea Paykel's semi-structured interview for Rec
ent Life Events was administered to patients affected by secondary ame
norrhea and also to healthy volunteers. The number, quality, and objec
tive negative impact of life events were compared among different horm
onal subtypes of secondary amenorrhoea and healthy normally menstruati
ng women, as a control group. The number of life events in amenorrhoei
c patients (N = 131) was significantly greater than those observed in
the control group (N = 64) (45.9 vs 32.8%). Moreover, where only hypot
halamic hypogonadotrophic amenorrhoea was considered, the occurrence o
f life events was significantly higher (59.8%) than in hyperandrogenic
(26.6%) or in normogonadotrophic (20.4%) patients. The most prevalent
events among hypothalamic hypogonadotrophic amenorrhoeic patients wer
e those classified as 'undesirable', 'uncontrolled' and with 'Objectiv
e Negative Impact'. The present study supports the hypothesis of a cau
se-effect relationship between stressful personal life events and the
onset of secondary amenorrhoea of hypogonadotrophic subtype.
