Detailed Description
Time of recruitment: 1 December 2021 - 30 April 2022. Two thousand women who meet the following criteria are to be recruited:(1) primparious women; (2) full-term delivery;(3) age ≤35 (4) breastfeeding within 7 days after delivery; (5) with autonomous behavior ability; (6) provide voluntary informed consent; (7) ability to breastfeed individually(8) prenatal breast ultrasound shows no breast lesions.. Exclusive criteria: (1) abnormal breast or nipple development (Poland syndrome or degree II and above inverted nipple); (2) history of breast surgery; (3) history of chest radiotherapy; (4) history of malignant tumors; (5) History of mastitis; (6) severe cardiovascular and cerebrovascular diseases, chronic diseases (Ecog score >3, long-term medication affects breastfeeding); (7) skin diseases or connective tissue diseases; (8) Hepatitis, syphilis, gonorrhea, AIDS and other infectious diseases. Criteria of elimination after recruitment: (1) failure to follow the breastfeeding instruction; (2) painless breast mass.
Participants are to be randomly divided into the interventional group which provides guidance on gravitationally assisted breastfeeding, and into the control group which provides general breastfeeding guidance. Through the social media network WeChat, each participant receives breastfeeding guidance before their first breastfeeding, and once a month until 6 months after childbirth. Additionally, at 3 and 6 postpartum, the breasts will be examined by a breast surgeon at Shenyang Women and Infants Hospital. Infant's height and weight will be measured and recorded at 6 months. The incidence of breastfeeding mastitis and the rate of baby weight gain are compared between the groups. This clinical cohort study aims to investigate effects of scientific guidance on the gravitationally assisted breastfeeding positions on the occurrence of breast mastitis.

---|---|
Control group
Under the professional guidance of doctors, participating women (1) breastfeed individually without using a breast pump; (2) massage their breasts 4 times a day for 15 minutes each time; (3) breastfeeding time is scientifically matched with infant's schedule; (4) alternative breastfeed, ensuring emptying one breast within 24 hours.
Doctors follow up once a month via WeChat.
Participants complete the questionnaires.
A breast ultrasound will be performed every three months.
The infant weight will be measured and recorded 6 months after breastfeeding
|
Prior to the first breastfeeding after delivery, the guidance of gravitationally assisted breastfeeding will be provided.
The primary breastfeeding position is advised to be the sitting position, supplemented by the lateral position with a time ratio of 4:1.
The following guidance will also be given: (1) participating women breastfeed individually without using a breast pump; (2) massage their breasts 4 times a day for 15 minutes each time; (3) breastfeeding time is scientifically matched with infant's schedule; (4) alternative breastfeed, ensuring emptying one breast within 24 hours.
Doctors follow up once a month via WeChat.

A breast ultrasound will be performed every three months.
The infant weight will be measured and recorded 6 months after breastfeeding.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The occurrence of lactational mastitis during breastfeeding
Time Frame: Six months
|
The incidence of lactational mastitis is defined as the proportion of breastfeeding mastitis that occurs during the period between the first breastfeeding and 6 months post-partum.
|
Six months
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Breast swelling and pain
Time Frame: Six months
|
Mastitis is caused by the failure of milk to discharge in time, resulting in milk accumulation.Milk accumulation is a prodrome of lactational mastitis.
