Course of maternal fatigue and its associated factors during the first 6 months postpartum: a prospective cohort study.
Hiroko Iwata, Emi Mori, Akiko Sakajo and 3 others
PMID 29599994WHAT IT FOUND
First-time mothers had the highest fatigue in the first month, while mothers who already had children saw fatigue rise again by six months.
Poor sleep, child-rearing worries, low social support satisfaction, financial burden and short meal times were linked to higher fatigue.
Key findings
01Fatigue peaked at 1 month postpartum for all groups, but parity changed the trajectory: primiparas improved after 1 month, while multiparas saw fatigue increase again from 4 to 6 months.
02Satisfaction with sleep was the strongest factor associated with maternal fatigue, followed by concerns about child-rearing.
03Factors consistently linked to higher fatigue across both time periods included dissatisfaction with sleep, concerns about child-rearing, financial burden, short meal times, and dissatisfaction with social support.

What it does not show
The study did not include any pre-birth data, so it cannot account for fatigue levels during pregnancy. The models explained only 34% and 41% of the variance in fatigue, indicating other significant factors were not measured. Findings cannot be generalized to mothers of multiple births (twins, triplets, etc.), who may experience higher fatigue. The study was conducted in Japan, so cultural attitudes toward childcare and social support may limit applicability in other countries.
Declared interests
The authors declared no conflicts of interest. The study was part of a larger research project funded by the Japan Society for the Promotion of Science.
The easy way to misread this
Do not assume that fatigue improves steadily for all mothers after the first month. Multiparas experienced a significant increase in fatigue between 4 and 6 months postpartum, meaning support needs to continue beyond the immediate newborn period for families with older siblings.
