- Breastfeeding rate survey: Analysis by combining factors of presence of previous delivery and age in Japanese women Shigeru Nishimaki Kazuhiro Iwama Masafumi Yamamoto Takeshi Ikegaya Azusa Uozumi Pediatrics International Abstract Background Age and presence of previous delivery are inextricably linked to breastfeeding. This study aims to examine breastfeeding during the first year after childbirth by combining four factors: primiparas and multiparas, as well as ages <35 years and ≥35 years. Methods Four hundred thirty‐six healthy mothers and their infants (vaginally delivered singleton term infants with birth weight >2500 g) were divided into four groups: (1) 134 pairs of primiparas aged <35 years and their infant (P [<35] group), (2) 72 pairs of primiparas aged ≥35 years and their infant (P [≥35] group), (3) 108 pairs of multiparas aged <35 years and their infant (M [<35] group), and (4) 122 pairs of multiparas aged ≥35 years and their infant (M [≥35] group), and the breastfeeding rate was examined at 0, 1, 2, 4, 6, 8, 10, and 12 months after childbirth. Results The percentage of the 436 cases with only breastfeeding was 59.6% at 0 months, 69.1% at 4 months, and 56.6% at 12 months. Comparing the four groups, the percentage with only breastfeeding in decreasing order was M [<35] group (70.8%–85.8%, range of rates at each time point) > M [≥35] group (57.9%–69.4%) > P [<35] group (47.8%–61.2%) > P [≥35] group (36.1%–51.4%). Conclusions There were difficulties with breastfeeding for primiparas, especially those aged ≥35 years. We propose that breastfeeding should be analyzed by combining maternal age and presence or absence of previous delivery together rather than as independent factors. 10.1111/ped.70029 http://onlinelibrary.wiley.com/termsAndConditions#vor
