Abstract: |
Background: Exclusive breastfeeding
for first 6 months of life is recommended under Infant and Young Child
Feeding practices in India. The objective of present study was to estimate
the prevalence of exclusive breastfeeding during first 6 months of life
of babies and to identify factors that interfere with the practice in
the study area. Methods: A prospective
cohort of 462 women who delivered at maternity unit of Government Medical
College & Hospital, Rajkot, which is a tertiary care centre for
the district, was studied. Data collection was done at hospital as well
as during home visits of babies at 1, 3 and 6 months. Factors related
to cessation of breastfeeding were analyzed using univariate, bivariate
and multivariate analysis. Results: All 462 mothers
reported breastfeeding their newborns. Prevalence of exclusive breastfeeding
reported at 3 months was 97% which declined to 62% by 6 months of age
of infants. Bivariate analysis revealed no significant association between
interruption of exclusive breastfeeding before 6 months of age and various
demographic, socioeconomic, maternal and infant characteristics. Multivariate
analysis by logistic regression demonstrated no association between
discontinuation of exclusive breastfeeding and socioeconomic status,
maternal education and maternal age, number of antenatal visits, maternal
employment and initiation of breastfeeding after delivery. Conclusion: Exclusive breastfeeding
prevalence rate found higher than at national level indicating better
feeding practices in these part of India. Also, factors classically
considered as supportive for breastfeeding had shown no association
with breastfeeding pattern in present study.

Breastfeeding
provides adequate and essential nutrients for infant’s growth and
development, protects infants against infections and ensures chances
of survival. The benefits of breastfeeding, especially exclusive breastfeeding
are well established 1, 2 particularly in poor environments
where early introduction of other milk is of particular concern because
of risk of pathogens contamination and over dilution of milk leading
to increased risks of morbidity and undernutrition.2 Based
on scientific evidence, the World Health Organization (WHO) recommends
the practice of exclusive breastfeeding the infants for first 6 months
after their birth, in addition to its continuation with supplementary
foods until 2 years or more. 3 Till the beginning of this
century, breastfeeding was accepted and practiced as routine. Data from
last few years showed varied improvement in breastfeeding rates.4 Studies have proved with no doubt that children exclusively
breast fed are less prone to diseases such as diarrhea5
and dehydration.6 There is also evidence that early breastfeeding
reduces the rate of hospitalization due to pneumonia.7
Some studies8 reveal factors, positively associated with exclusive breastfeeding,
such as higher maternal educational level, gestational age greater than
37 weeks, mothers with previous experience of breastfeeding. There are
also studies that relate factors leading to interruption of exclusive
breastfeeding such as low family income, low maternal age, primiparity
and mothers returning to work.9 Several studies intended
to define determinant variables in the success or failure of breastfeeding
10,11, which could ease the planning of promotional strategies.
Nevertheless, it is always prudent to consider that, as an eating habit,
breastfeeding is intrinsically related to social, cultural and traditional
patterns of a given population. This fact justifies need for regional
studies that allows more efficient action in regard to measures for
intervention, based on knowledge of local reality. The objective of
this study was to evaluate the prevalence of exclusive breastfeeding
during first 6 months of life of babies in Rajkot, and to identify factors
that interfere with practice.
A prospective
cohort study included women who gave birth at maternity unit of Government
Medical College & Hospital, Rajkot and a tertiary care centre for
the district. Tertiary care hospital implies round the clock availability
of specialists like, obstetricians and gynecologists, anesthetists,
and facilities for blood transfusion & other similar interventions.
The present study was hospital based and the hospital under study mainly
caters people from lower socio-economic strata.
Breastfeeding found a common practice in these region of India and usually
all the mothers delivering offers breastfeeding to their infants as
soon as after birth. By considering prevalence rate of exclusive breastfeeding
46% as per National Family Health Survey (NFHS) -3, present study was
planned with purpose to know the prevalence rate in Rajkot.
Total 492 mothers
recruited who delivered from 1st January to 19th
February, 2007. The sample size calculated was 460 infants, using EPI
6 software with 39.7% children exclusive breastfed upto 6 months4, standard error of 5% and design effect 5. The study was planned
with purposive sampling, in which mothers were included from the beginning
of study period and on achieving the calculated sample size, data collection
was terminated. By considering 10% lost to follow up, 492 mothers were
considered for the study. Informed consent was obtained from mothers
who agreed to participate in study. To minimize bias, mothers were informed
that the study was on infant feeding practices rather than breastfeeding
practices. Women recruited for study were from homogenous group and
their socio-demographic variables did not differ from those who did
not participate in the study. Mothers were interviewed by trained personnel
either by home visits or telephone call at 1, 3 and 6 months after delivery.
Study group was free from contraindications against breastfeeding (e.g.
newborn with severe malformations or mothers seropositive for HIV).
A mother who delivered infant with congenital malformations was excluded.
Among 492 mothers who had given consent to participate, 462 (93.9%)
mothers could be interviewed 1 month after delivery. Among these 462
mothers, 397 (85.9%) mothers were interviewed by home visits and remaining
65 (14.1%) by telephone calls. Thirty mothers were lost to follow up.
Of these 30, eighteen mothers could not be traced and 12 lost their
interest in study. Successive interviews were conducted at 3rd
and 6th month after delivery among the 462 mothers who were
still breastfeeding at 1 month by home visits (85.9%) and by telephone
calls (14.1%).
The questionnaire
included information regarding demographic profile and socioeconomic
status of mother and her family, obstetric history and infant feeding
practices. Breastfeeding was defined into following categories by World
Health Organization12: exclusive breastfeeding as when child
is fed exclusively on human milk; predominant breastfeeding when child
is fed on human milk and other liquids like water, tea, juices; general
breastfeeding when all kind of milk, liquid and semisolid diet is given.
Statistics
EPI 6 and Epi
Info version 3.4 were used for data analysis, adhering to the hierarchical
model created previously, with variables related to demography (baby’s
sex, maternal age) and socioeconomic factors (family income, parent’s
education) at first level, maternal characteristics (parity, type of
delivery, place of delivery, number of antenatal visits, maternal employment,
received advice on exclusive breastfeeding during postnatal visits,
inter delivery interval [birth spacing], previous duration of exclusive
breastfeeding in multiparous) at second level, and at third level, infants`
characteristics (birth weight, initiation of breastfeeding, any breastfeeding
difficulties). The frequencies of variables were calculated and bivariate
analysis was performed between individual exposure factors and the outcome,
between exposure factors and other variables and between the outcome
and other variables. For all data analysis, cutoff for statistical significance
was set at p<0.05. For multivariate analysis all variables
whose associations with outcome had the p value <0.20 were
selected in order to study possible confounding factors. Experimental
research that is reported in the manuscript has been performed with
approval of ethical committee of the Government Medical College, Rajkot
(reference number was not provided). Research carried out on humans
is in compliance with the Helsinki Declaration.
Nine out of
ten participants were literate; 86% were aged more than 20 years and
84% belonged to low socioeconomic class. A little more than 2/5th
of study population (43%) was primiparous and 86% had normal delivery.
Majority of mothers had attended more than 3 antenatal visits. One fifth
of the mothers delivered low birth weight (< 2500 grams) babies.
As shown in table 1, deliveries among 86% of the study population were
conducted in hospital. Fourteen percent mothers returned to usual work
within 6 months of delivery.

The breastfeeding
initiation rate in this study was 100%. Prevalence of exclusive breastfeeding
at 3 months was 97% which was reduced to 62% at the end of 6 months
of infant`s age. The use of water, tea, juice etc was found in remaining
study sample but solids were not introduced in any infant.

Factors like
socio-economic status, maternal education, mother`s age, number of antenatal
visits and maternal employment were analyzed for multivariate analysis
but none were found statistically significant.
Exclusive breastfeeding
is safe, economical and emotionally satisfying means of feeding babies.
In countries where lactation support is available, six months exclusive
breastfeeding has improved substantially over time.3 This
study enabled to evaluate the rate of exclusive breastfeeding and to
determine factors associated with cessation of exclusive breastfeeding
within first 6 months of life. In present study, the prevalence rate
of exclusive breastfeeding by 6 months was 62%, compared to 46% at national
level.13 Foo LL et al 14 reported prevalence rate of 21%
which is very low compared to present study.
Present study
showed no association between parental education, and mother’s employment
with exclusive breastfeeding. It differs with Agampodi SB et al15 study which associates influence of parental education and
women’s employment on breastfeeding practices. The reason may be because
of better health services available under Integrated Management of Neonatal
& Childhood Illness (IMNCI). Several studies 16,17 recommended
implementation of IMNCI in India. Present study showed no association
between living conditions and cultural habits of population with breastfeeding
practices during first 6 months of child birth in contrast to Mascarenhas
MLW et al9 study. After detailed analysis by adjusted logistic
regression, no significant association was found with birth weight,
while comparing another study in which low birth weight was negatively
associated with initiation and continuation of exclusive breastfeeding.18
No association
was found between breastfeeding pattern and variables, classically considered
as supportive for breastfeeding such as number of antenatal visits,
mothers receiving postnatal breastfeeding advice, previous breastfeeding
duration in multiparous, start of breastfeeding after birth, which was
in accordance with Caldeira AP et al.19 The possible justification
for such findings could be excellent execution of maternal and infant
care which includes promotion of breastfeeding in health services especially
after introduction of IMNCI training in Gujarat state, an Indian modification
of Integrated Management of Childhood Illness (IMCI) which promotes
exclusive breastfeeding for first 6 months of life. Breastfeeding is
a maternal option that involves a complex interaction of socioeconomic,
cultural and psychological factors and many more. However, as a socially
recreated habit, the role of reproductive and child health services
in promoting of breastfeeding should by no means be disregarded.
There is an
intricate relation among the determinants of successful breastfeeding practice,
but present study did not aim at discussing it deeply. Authors believe that
while defining breastfeeding pattern in a certain region, it is of utmost
importance that all intervening variables be considered, allowing a thorough
knowledge of situation, and ensuing a greater potential for planning and
intervening.
Present study
alerts us that in spite of prevalent practice of breastfeeding, promoting
and strengthening reproductive and child health services is of paramount
importance, since unsatisfactory behavior, regarding exclusive breastfeeding
is still observed. Further studies are necessary to correlate the interrelations
among these several variables and also other psychological and anthropological
questions (not considered in this study) that are known to certainly
interfere in breastfeeding practice.
There were
several limitations in this study. Main clientele was from low socioeconomic
strata attending a tertiary care center and hence it may not be a representative
of the general population. Overestimation of proportion of exclusive
breastfed is possible due to selection bias. Good numbers of subjects
were from urban area and they might have more exposure to the facts
of importance of breastfeeding.
Exclusive breastfeeding
prevalence rate found higher than at national level indicating better
feeding practices in these part of India. Also, factors classically
considered as supportive for breastfeeding had shown no association
with breastfeeding pattern in present study, needs promotion 20,
21 & improvement of maternal & child health services. Impact assessment
of IMNCI introduction should be carried out to identify changes in knowledge,
attitude and practice regarding breastfeeding over a period of time. We acknowledge
