Adolescents and young women with functional hypothalamic amenorrhoea: is it time to move beyond the hormonal profile?

PURPOSE: To ascertain the role of deranged eating behaviours (DEBs) in the development of functional hypothalamic amenorrhoea (FHA) and the reciprocal role of psychopathological traits on both disorders. METHODS: A prospective case-control study was conducted spanning the period January 2016 to April 2018. Forty-one consecutive FHA females and 86 healthy controls were recruited. We assessed the DEBs and other FHA predisposing factors via self-reported questionnaires. Possible correlations amongst the variables were examined using the Spearman's correlation coefficient (rho), whilst multivariate logistic regression was carried out to identify independent predictors of DEBs. RESULTS: Mean scores on Eating Attitudes Test-26 (EAT-26) were significantly higher in females with FHA (p < 0.0001). Women with FHA were characterised by significantly higher scores at the sub-scale items of dieting (p = 0.03) and bulimia and food preoccupation (p < 0.001) compared to healthy controls. Significant difference was also observed between the mean scores of the two groups in all other questionnaires: State-Trait-Anxiety-Inventory (STAI) (p < 0.0001), Multidimensional Body-Self-Relations Questionnaire (MBSRQ) (p < 0.0001) and International Physical Activity Questionnaire (IPAQ) (p = 0.004). EAT-26 scores were positively correlated with scores on STAI (ρ = 0.26, p = 0.04), MBSRQ (ρ = 0.79, p < 0.0001) and IPAQ (ρ = 0.35, p = 0.03). High scores on IPAQ and STAI were correlated with a 12.2-fold (p = 0.008) and 4.3-fold (p = 0.04) increased risk for high scores on EAT-26 respectively. CONCLUSIONS: DEBs may occur in FHA populations at a higher frequency compared to the general population. Anxiety and overweight preoccupation may underlie and independently contribute to development and maintenance of both DEBs and FHA. This evidence may have future implications for both screening and interventions that target DEBs and other psychological factors.

Poor sleep and high anxiety levels in women with functional hypothalamic amenorrhoea: A wake-up call for physicians?

OBJECTIVE: To assess sleep disorders (SleD) in women with functional hypothalamic amenorrhoea (FHA) and to identify possible associations with known FHA predisposing factors. STUDY DESIGN: We conducted a prospective case-control study spanning the period January 2016 to April 2018. We recruited forty-one FHA women and 86 healthy controls. We assessed SleD and other FHA predisposing factors via self-reported questionnaires. The Spearman's correlation coefficient (rho) was used to examine possible correlations among the different variables. Multivariate logistic regression analysis was conducted to identify independent factors associated with SleD. RESULTS: Women with FHA reported having higher SleD (p = 0.004), abnormal eating attitudes (p < 0.0001), higher anxiety levels (AL) (p < 0.0001), overweight preoccupation (P < 0.0001) and increased weekly physical activity (p = 0.004). There was a significant positive correlation between SleD and AL (rho = 0.88, p < 0.0001). Significant correlation was also found between AL and several Athens insomnia scale constituents, including sleep induction (rho = 0.53, p = 0.0004), awakenings during the night (rho = 0.6, p < 0.0001), final awakening (rho = 0.42, p = 0.006), total sleep duration (rho = 0.64, p < 0.0001), quality of sleep (rho = 0.63, p < 0.0001), well-being during the day (rho = 0.34, p = 0.03) and sleepiness during the day (rho = 0.51, p = 0.007). High AL were correlated with 2.83-fold increased SleD risk (p = 0.04). CONCLUSION: FHA women are seemingly more prone to SleD and those with SleD suffer from higher AL. In view of this evidence, the potential rationale of adding psychological and SleD evaluation to their clinical care is highlighted.
