ABSTRACT To study the effects of caesarean section on breastfeeding.
Six hundred and two [301 cases was caesarean section (caesarean section group) and 301 cases was vaginal delivery (vaginal delivery group)] nulliparas were interviewed face-to-face at antepartum and postpartum in an indication-matched prospective study.
There was a significantly lower postpartum prolactin (PRL) level in the caesarean section group (8.48 nmol/L, 95% CI: 7.80 - 9.21 nmol/L) compared with vaginal delivery group (9.61 nmol/L, 95% CI: 8.99 - 10.26 nmol/L) during 6 - 24 hours in the daytime after delivery. The median time of breastfeeding initiation was 12 hours and 2 hours after birth for caesarean section and vaginal delivery groups respectively. Caesarean section was an important hazard for a shorter duration of breastfeeding (RR = 1.21; 95% CI: 1.10 - 1.33) within one year after childbirth.
Caesarean section is associated with significantly lower postpartum PRL, which is in line with the longer breastfeeding initiation and lower rate of successful breastfeeding. Necessary measures including promoting the secretion of postpartum PRL such as early contact, early sucking and analgesic method should be taken to improve the successful breastfeeding rate.

    ABSTRACT: Cesarean delivery has increased significantly during the last decades. This study aimed to investigate the association between planned mode of delivery and method of feeding. A cohort was created retrospectively using data from a population-based maternal and child health surveillance system, which covers 27 study sites in China from 1993 to 2006. The cohort consisted of 431,704 women for analysis, including 22,462 women with planned cesarean delivery on maternal request (CDMR) and 409,242 women with planned vaginal delivery (VD). Logistic regression models were used to examine the association between mode of delivery and method of feeding adjusting for selected covariates. In this cohort, 398,176 (92.2%) women exclusively breastfed their baby, 28,798 (6.7%) women chose mixed feeding, and 4,730 (1.1%) women chose formula feeding before hospital discharge. Women who planned CDMR were less likely to exclusively breastfeed and more likely to formula feed their babies than those who planned VD. After adjusting for covariates, the odds ratios were 0.85 (95% CI: 0.81-0.89) for exclusive breastfeeding and 1.61 (95% CI: 1.45-1.79) for formula feeding. Associations between planned mode of delivery and method of feeding in the south, north, rural and urban areas yielded similar results. This study demonstrated that planned CDMR was associated with a lower rate of exclusive breastfeeding and a higher rate of formula feeding in a low-risk Chinese population.

    ABSTRACT: Breast feeding has a great impact on the infant morbidity and mortality. According to Pakistan Demographic and Health survey (PDHS) infant mortality rate is 78 deaths per 1,000 live births. World Health Organization recommends that exclusive breast feeding for six months can decrease infant mortality rate by one-third. The objective of the study was to find out how the mode of delivery had impact on the practice of breast feeding. Data were collected for 2500 consecutive patients during a period of two years, and it was seen that maternal initiative to breast feed was low and problems with lactation were much more in cases delivering their babies via cesarean sections than those delivering theirs by normal delivery. Vaginal and cesarean section deliveries took place in 54% and 46% of the case, respectively. Thirty percent of the women studied felt that they had no problems regarding breastfeeding, but 70% of them had some sort of problems with breastfeeding their babies. When the women were matched for the mode of delivery, 58% of women who had breastfeeding problems belonged to the cesarean delivery group and 42% of complaining mothers were from women with normal delivery. The relative risk of having problems with breastfeeding for women subjected to cesarean was 1.38 and the odds ratio was 0.61. The findings of the present study indicate that more in depth counseling sessions are required for women undergoing operative delivery to improve breast feeding among them.

    ABSTRACT: To describe breastfeeding practices in rural China using globally recommended indicators and to compare them with practices in neighbouring countries and large emerging economies. A community-based, cross-sectional survey of 2354 children younger than 2 years in 26 poor, rural counties in 12 central and western provinces was conducted. Associations between indicators of infant and young child feeding and socioeconomic, demographic and health service variables were explored and rates were compared with the most recent data from China and other nations. Overall, 98.3% of infants had been breastfed. However, only 59.4% had initiated breastfeeding early (i.e. within 1 hour of birth); only 55.5% and 9.4% had continued breastfeeding for 1 and 2 years, respectively, and only 28.7% of infants younger than 6 months had been exclusively breastfed. Early initiation of breastfeeding was positively associated with at least five antenatal clinic visits (adjusted odds ratio, aOR: 3.48; P < 0.001) and negatively associated with delivery by Caesarean (aOR: 0.53; P < 0.001) or in a referral-level facility (aOR: 0.6; P = 0.014). Exclusive breastfeeding among children younger than 6 months was positively associated with delivery in a referral-level facility (aOR: 2.22; P < 0.05). Breastfeeding was not associated with maternal age or education, ethnicity or household wealth. Surveyed rates of exclusive and continued breastfeeding were mostly lower than in other nations. Despite efforts to promote breastfeeding in China, rates are very low. A commitment to improve infant and young child feeding is needed to reduce mortality and morbidity.
