Predictors associated with night sleep disturbance among breastfeeding women.

Objective: The aim of this study was to investigate the incidence of somnological disorders among Kazakhstani women who breastfeed and to assess the association of this phenomenon with some medical and social characteristics.

Methods: The authors used the standardized questionnaire of A.M. Vein and Y.I. Levin to assess nocturnal sleep among 1101 breastfeeding women in the Republic of Kazakhstan, applied Pearson's chi-square test to study the correlation between sleep disturbances and duration of breastfeeding, and multiple logistic regression to assess the influence of various medical and social factors on somnological disorders. Data collection occurred in February 2023.

Results: On average, 80% of breastfeeding women (ranging from 79% to 85.9%) experienced some form of nocturnal sleep disorders, with no significant association found between these disorders and breastfeeding duration (p = 0.234), while urban residence, history of operative delivery, child's health issues, and low satisfaction levels with various aspects were associated with over twofold increased odds of experiencing sleep disorders (p ≤ 0.05).

Conclusions: The elevated prevalence of nocturnal sleep disorders among breastfeeding Kazakhstani women serves as a risk indicator for adverse health outcomes, with predictors including place of residence, obstetric complications, child health issues, and satisfaction levels with social conditions and personal expression opportunities.
