Objectives
1. Look at the prevalence of Cesarean Sections worldwide
and in Lebanon
2. Discuss the underlying factors
3. Review the short and long-term effects of C section on
the health of mothers and newborns.
4. Recommend solutions to reduce the rate of unnecessary
C Sections

World Health Organization
 Recommended rate of C section : Not to exceed 15%
(1985)
 A study published in December 2015 in JAMA indicates
that if the CS rate increases to 19%, maternal and neonatal
mortality decline
 A CS rate above this level did not lead to any improvement
in maternal and neonatal mortality rates

PLoS ONE 11 (2): e0148343. doi:10.1371/journal.pone.0148343

Rising Trends of Cesarean Section Worldwide:
A Systematic Review
Soto-Vega E. et al. Obstet Gynecol Int J 2015, 3(2): 00073

Lebanon
 The Lebanese literature demonstrated that this rate
increased alarmingly since the beginnings of the 1990s, as
it reached:
 33% of total deliveries in 1996
 35% in 2004
 40.8% in 2008
(Abdallah et al, 2004; DeJong et al., 2010; Mroue, 2011)
 Latest figures reported from the MoPH in 2013 showed
that the rate of C Section reached 44-45 % of total
deliveries covered by MoPH.

• The study was conducted through GlobeMed’s portfolio
• The majority of centers included in the study were private
hospitals
• Between January 2000 and December 2015 : 29,878
pregnant women were included in the study.

Prevalence and Causes of Cesarean Section in
Iran
Systematic Review and Meta-Analysis
Saber AZAMI-AGHDASH et al. Iran J Public Health. 2014 May; 43(5): 545–555.

No preparation for the pregnant mom
 Prenatal classes
 Relaxation methods
 Breathing
 Physical activity and muscle strengthening

Once a C section, always a C section!
 Vaginal Birth after CS (VBAC) that is rising in developing
countries and contributing to the reduction of repeated CS
rate constitutes only 0.2% of deliveries in Lebanon.
 This low rate indicates that women who undergo primary CS
are more likely to go through repeated CS in Lebanon (WHO,
2010)

Non-reassuring fetal heart rate
 Almost all hospital births include continuous monitoring of
the fetal heart beat.
 These monitors are highly unreliable, which means that a
majority of babies identified to have “non-reassuring”
heart rate patterns by continuous electronic monitoring
may not be compromised at birth.

3. WHAT ARE THE ADVERSE EFFECTS OF C SECTION?

Risks of C section (Mother)
C Section increases adverse health consequences such as:
 Need for antibiotic treatment (Smaill & Gyte, 2010)
 Blood transfusion (Rouse et al., 2006)
 Urinary tract infections, bladder damage, uro-genital tract
injury, backache, thromboembolism … (Carayol et al., 2008;
Mazzoni et al., 2010; Khunpradit et al. 2011; Lavender et al., 2012; Main et al.,
2012; Huster, 2013; Teixeira et al., 2013)
 Hysterectomy (Rooney et al., 2005; Whiteman et al., 2006)
 Death (Kacmar et al., 2003; Rooney et al., 2005)

Long-term risks and benefits associated with cesarean
delivery for mother, baby, and subsequent pregnancies:
Systematic review and meta-analysis
 Lower rate of fertility
 Pregnancy after cesarean delivery was associated with
increased risk of miscarriage (OR 1.17) and stillbirth (OR
1.27), but not perinatal mortality (OR 1.11)
 Pregnancy following cesarean delivery was associated
with increased risk of placenta previa (OR 1.7), placenta
accreta (OR 2.95), and placental abruption (OR 1.38)
Oonagh E. Keag et al. PLOS Medicine | https://doi.org/10.1371/journal.pmed.1002494 January 23, 2018

Elective C section and the late preterm
 Pregnancy dating has an error margin of 2-3 weeks
 Most elective C-sections are performed around 36 weeks of GA
 The late preterm newborn (34-37 weeks GA) is prone to the
following risks:
1. Hypothermia
2. Respiratory distress and TTN (3 x more than at 39 weeks)
Stutchfield P, Br Med J 331(7518):662; 2005
3. Hyperbilirubinemia and Hypoglycemia

Risks of C section (Baby)
 Neonatal intensive care unit admission (Hannah et al., 2000;
Stutchfield et al., 2005)
 Many systematic reviews showed that C sections are highly
associated with childhood overweight and obesity (Li et al,
2013; Huh et al., 2012; Barros et al., 2012) respiratory complications
like pulmonary hypertension and asthma besides brain
damage in some occasions (Main et al., 2012; Zanardo et al., 2004;
MacDorman, 2008).
 CS were also associated with a decrease of breastfeeding
rates (Rowe-Murray & Fisher, 2002; Zanardo et al., 2010; Merten et al., 2007;
Labbok & Taylor, 2008).

Fluid in the lungs of the fetus
 Lungs are full of fluid in fetal life (38 ml/Kg)
 Resorbed shortly after birth
 In NVD with natural labor 40% of the alveolar fluid is
resorbed before birth due to the action of stress
hormones
 In elective C section there is no labor and no stress
hormones, therefore the baby frequently ends up in the
NICU
Lucky Jain, Physiology of fetal lung fluid clearance and the effect of labor Semin Perinatol 30, 2006

Breastfeeding after cesarean delivery:
a systematic review and meta-analysis of
world literature
 The systematic review included 53 studies (554,568
subjects, 33 countries); 25 authors contributed additional
data (245,455 subjects), and 48 studies (553,306 subjects,
31 countries) were included in the meta-analysis.
 Rates of early breastfeeding were lower after CD compared
with after VD (pooled OR: 0.57; P < 0.00001)
Prior E. Am J Clin Nutr. 2012 May;95(5):1113-35

Birth by cesarean section
in relation to adult offspring overweight
and biomarkers of cardio-metabolic risk
Methods:
 The Danish Fetal Origins Cohort enrolled 965 pregnant women
in 1988–1989.
 In 2008, a follow-up study of the offspring was completed.
Results:
 Birth by C-section was associated with increased odds of
overweight or obesity at 20 years (OR=2.17 ) after adjustment
for potential confounders.
 Birth by C-section was also associated with higher serum
concentrations of total cholesterol (8.5%), LDL cholesterol
(12.6%), leptin (73.1%) and Apolipoprotein B (0.08 g/l)
S. Hansen et al. International Journal of Obesity 42, 15–19 (2018)

Long-term risks and benefits associated with cesarean
delivery for mother, baby, and subsequent pregnancies:
Systematic review and meta-analysis
 One RCT and 79 cohort studies were included, involving
29,928,274 participants.
 Children delivered by cesarean delivery had increased risk
of asthma up to the age of 12 years (OR 1.21, 1.11 to 1.32; n
= 887,960; 13 studies) and obesity up to the age of 5 years
(OR 1.59, 1.33 to 1.90; n = 64,113; 6 studies).
Oonagh E. Keag et al. PLOS Medicine | https://doi.org/10.1371/journal.pmed.1002494 January 23, 2018

Caesarean Section is associated with reduced perinatal
cytokine response, increased risk of bacterial
colonization in the airway, and infantile wheezing
 Children delivered by CS were associated with
increased risk of wheezing (aHR 1.63; 95% CI: 1.01–
2.62) and decreased compliance of the respiratory
system at 12 months (p = 0.045).
 CS was associated with reduced TLR1–2- triggered TNF-
α and IL-6 responses at birth.
 By 12 months of age, children delivered by CS had
significantly less airway bacterial clearance.

The Elevated Rate of Cesarean Section and Its Contribution to
Non-Communicable Chronic Diseases in Latin America:
The Growing Involvement of the Microbiota
 Conclusion : The establishment of the gut microbiota is
delayed in infants born by C-section during the postnatal
period, during a critical developmental window for the
maturation of the newborn’s immune system.
 This delay may favor the subsequent development of
inflammatory and metabolic disorders during childhood
Magne F et al. Front. Pediatr. 5:192. doi: 10.3389/fped.2017.00192

 The mother's vaginal bacterial community was similar to
her own baby's microbiota (vertical transmission)
 In contrast, skin bacterial communities of C-section
mothers were not that similar to their own babies
 These results suggest that incidental exposures to skin
bacteria in the hospital environment could contribute to
the microbiota of C-section delivered babies

Partial restoration of the microbiota
of cesarean-born infants via
vaginal microbial transfer
 Samples from 18 infants and their mothers, including 7 born vaginally and
11 delivered by scheduled C-section, of which 4 were exposed to the
maternal vaginal fluids at birth.
 Briefly, the microbial restoration procedure consists of incubating a sterile
gauze in the vagina of mothers that are negative for Group B streptococcus
(GBS) during the hour preceding the C-section.
 Before C section the gauze is withdrawn and put in a sterile container at
room temperature
 Within the first two minutes of birth, babies were swabbed with the gauze,
starting with the mouth, then the face, and finally the rest of the body

The Dutch experience
 C section rate 14% in 2000-2001
 Increased to 16.7% in 2010
 Fetal and early neonatal morbidity decreased in the same time
period from 0.53% to 0.21%
 30 % of all deliveries were done at home assisted by the
midwife
 There are no epidurals at homes
 All expenses at home are for free
 Non-indicated C sections at hospital are self-payed by the
patient

Take home message
1. The rate of C section in Lebanon has reached unacceptable
levels
2. Improving women's knowledge about the risks and
benefits of different modes of delivery can lead to a
positive maternal attitude towards vaginal delivery.
3. Prenatal classes (Free and monthly)
4. Increase the quality of vaginal delivery services ( and
possibly fees) and cover for epidurals by official 3d party
payers
5. Prevent the first cesarean delivery.
6. Encourage breast-feeding
