Abstract
Objective Mothers of preterm infants face unique challenges in establishing milk supply. We
hypothesized that daily meditation practice while pumping would increase milk volume.
Study Design This was a randomized control trial examining the effect of meditation on the breastmilk
supply of women delivering preterm infants. The meditation group engaged in daily
use of a mindfulness-focused meditation app in addition to routine lactation support.
The primary outcome was mean breastmilk volume on the infant's nineth day of life.
Secondary outcomes included use of lactation-promoting behaviors, continuation of
breastfeeding, and measures of mental health and breastfeeding self-efficacy by validated
questionnaires. In addition to the intention to treat analysis, a per protocol analysis
examined the association of frequent meditation with these breastfeeding and mental
health outcomes.
Results A total of 60 women were analyzed. Mean milk volume was 647.1 ± 467.8 mL in the meditation
group and 514.9 ± 393.5 mL in the routine care group (p = 0.27). Median number of pumping sessions was 7 (interquartile range [IQR] 5–8)
in the meditation group, compared to 6 (IQR 4–7) in the routine care group (p = 0.11). Other lactation-promoting behaviors, breastfeeding continuation, and questionnaire
scores were similar.
Adjusting for confounders, we found an increase in breastmilk production of 223.2 mL
(95% CI 98.8–347.5, p = 0.001) and in pumping episodes by 0.93 (95% CI 0.16–1.70, p = 0.020) associated with frequent meditation. Skin-to-skin contact was increased
to 100% (p = 0.006) among women who meditated seven or more times. Adjusted odds of a clinically
significant Edinburgh Postnatal Depression Scale score of >9 was 0.057 (95% CI 0.0014–0.711,
p = 0.023) with frequent meditation.
Conclusion Breastmilk production was similar in mothers practicing meditation compared to those
receiving routine lactation support. For women engaging in frequent mediation, there
may be an effect in establishing breastmilk supply and reduction of depression symptoms.
Key Points
Breastmilk is not increased for neonatal intensive care unit (NICU) moms asked to
engage in meditation.
Maternal mental health is not improved among NICU moms asked to meditate.
However, higher-frequency meditation is associated with increased milk volume and
lower odds of high scores on depression screening.
