Introduction
Nutrition is one of the easily modifiable environmental factors that
can affect growth, development, infant metabolism, and the immune
system. Good nutrition during first thousand days of life is critical
and crucial for healthy growth and neurological development across
the lifespan. Nutrition during this period is of importance because
it positively affects the child physical and cognitive development.
[1] Introduction of complementary feeding which should begun
from 6 months onwards is associated with major changes in
both macronutrient and micronutrient intake.[4] This period is
characterized by rapid development and growth, exposing infants to
an increased risk of deficiencies, especially Iron Deficiencies and Iron
Deficiencies Anaemia, which are most common at this age affecting
an estimated 40% of children under five years of age in both low- and
high-income countries.[1] Consequently, complementary foods and
correct feeding practices can prevent malnutrition.
Infants born with cleft lip and or palate have problems with
feeding in varying degrees. The extent of feeding problem and
malnutrition varies with the severity of defect.[2] Irrespective of
the setting, infants born with an orofacial cleft have a heightened
risk of failure to thrive because their ability to suck and swallow is
compromised.[6] Malnutrition in infants with cleft can be attributed
to feeding challenges like poor oral suction, lengthy feeding times,
nasal regurgitation, excessive air intake, and inadequate volume of
oral intake.[2] Infants with CLP presents with unique nutritional
requirements and vulnerabilities.[3] Infants born with clefts require
prompt nutrition support to be ready for timely surgery. Maintaining
sufficient dietary intake is of paramount importance to build their
immunity and to allow adequate weight gain so that they can tolerate
stress of surgical interventions and hasten the healing process.[5]
Global estimate of malnutrition in children with cleft, born in
limited-resource settings is about 28% at the time of primary surgery
which is well above the global underweight prevalence in under-5
children without cleft estimated at about 13.5%.[6] From a study
conducted in India, 69.6% children with cleft below the age of 5 years
were malnourished. As per the WHO classification, 12.5% of children
were severely malnourished and 34.8% were mildly malnourished.[7]
Prevalence of all forms of malnutrition particularly wasting among
clefts is much higher than the national average.[8]Infants are more
susceptible to micronutrient deficiencies and the most common one
is anemia because of feeding difficulties where the infant with cleft
consumes less nutrients and repeated upper airways or middle ear
infections.[8] Iron deficiency with or without anemia in the first
6 months of life can adversely affect child’s physical and cognitive
development. The child with anemia is more vulnerable to infection
and has lower immunity. In infant with cleft, it also adversely affects
their wound healing in post cleft repair.[8]Few studies report the
prevalence of anemia among cleft (74.6%) higher than the national
average.[8]In another study, anaemia (microcytic hypochromic type)
was reported as 81.63% and eosinophilia was seen in 20.60% cases
which interferes with and delays the surgical management of these
patients. [9]
Body iron stores as measured by serum iron, serum ferritin
was much lower among children with cleft lip and/or palate when
compared to that of age-matched controls. The iron deficiency state
has no relation to the type of cleft present.[8] The other micronutrient
deficiencies commonly seen among children with both cleft lip and
palate are folate and vitamin B12 deficiency, compared to children
having only one of the two deformities.[8] Malnutrition among
patients with CLP is further exacerbated by surgical intervention,
wound healing and impaired postoperative feeding until the surgical
site heals. Surgery and wound healing results in a hypermetabolic
state during the postoperative period as the body responds to tissue
damage in turn increasing the demand for good nutrition.[8]
Most common type of malnutrition is protein deficiency and
micronutrient deficiencies.[11] Protein deficiency in infants with
cleft is characterized by stunted growth, lack of muscle mass, oedema
and delayed healing. The oedema and poor muscle mass might lead
to a compromised outcome of lip and palate surgeries attributed to
tension on the surgical closure line.[11] Malnutrition among infants
will have negative effect on surgical healing.[3] Poor perioperative
nutrition has been associated with higher complication rates in other
disciplines. Good nutrition plays a major role in surgical wound
healing and improves the surgical outcome.
Infant and young child feeding (IYCF) practices like early
initiation of breastfeeding, exclusive breast milk feeding, starting
of complementary feeding at 6 months, dietary diversity which are
suboptimal among under 5 infants both in with and without cleft
are the major reasons for malnutrition [7,10] Therefore, overcoming
nutritional inadequacies and providing nutrition information to
parents is critical in combating feeding issues and ensuring that
infants receive proper nourishment. Introduction of nutritious
complementary food during the perioperative stage which will
help in wound healing, quicker recovery from surgery and growth
is of paramount importance. Dietary diversification, fortification
of complementary foods and nutrition education are important
measures to improve the overall nutritional quality of the child’s diet
which in turn reflects in timely ready for surgery.[12]
Materials and Methods
Development of Product:
Infant of 6 -12months consumes small quantity of food hence it is
imperative to provide optimum nutrition at every meal. Home-based
meals, predominantly vegetarian may lack in many micronutrients
which creates a nutrition gaps and results in hidden hunger.[19]
In this context, iron fortification of complementary food made
from locally available grains to meet iron gap provide effective
strategy to combat malnutrition. Role of iron in neurodevelopment,
cognition and immunity during infancy cannot be undermined.
[19] According to National Health Family Survey 5 prevalence of
anemia among children age 6- 59 months is 67% and among infants
with cleft is 74%.[18] Zinc deficiency is associated with poor growth,
loss of appetite, skin lesions, impaired taste acuity, delayed wound
healing, hypogonadism, delayed sexual maturation, and impaired
immune response. Zinc is widely present in all food groups but the
bioavailability is low because of high amounts of inhibitors such as
fibre and phytate.[20] Hence it is important to fortify complementary
food with micronutrient to meet the gap. For this study a low-cost
complementary food will be prepared by mixing malted pearl millet,
roasted amaranth, roasted green gram. The domestic processing
of grains like soaking, germination and roasting will result in
lower levels of phytic acid, polyphenols and saponins and higher
bioavailability of proteins, iron and zinc than those of the raw grains
used for preparing mixtures. Food legumes are good source of
protein and continue to contribute significantly towards the protein
content of diets of people. Food fortification is one of the most
cost-effective ways of addressing development challenges in infants
according to 2008 Copenhagen Consensus. [22]Report from metaanalysis,
which included 18 randomized controlled trials and 5468
children, compared the impact of micronutrient-fortified milk and
cereal- based products versus similar non-fortified items on children
between 6 months and 5 years of age. The use of fortified milk and
cereal-based products was more effective in reducing anemia in
young children in developing countries, compared to the use of
non-fortified products.[22] On this rationale, study complementary
food was prepared by the above method and fortified with iron, zinc
and vitamin C and then evaluated for its nutritional characteristics.
Points to be considered when a food product is fortified with a trace
element is safety, beneficial effects of the trace element, influence on
the organoleptic properties of the food, and cost of the fortification.
Vitamin C was added to increase the iron absorption. This product
was developed and fortified as homemade and commercially available
food lacks micronutrients. Millet was used to bring in the dietary
diversity. The formulation was prepared in accordance to national
standards. Malt is fortified with ferrous fumarate, zinc sulphate and
vitamin c to achieve 75% of recommended allowance in per serving to
achieve 20% change in body iron stores. Study using ferrous fumarate
(FeF) as an iron compound, had stronger effect on iron status with
higher Hb and serum ferritin (SF) concentration and reduced anemia
and ID in infants receiving additional 5.5 mg or 12.5 mg iron per
day from a micronutrient-fortified maize porridge compared with
their control peers. [20,23] Fortified complementary food and the
unfortified complementary food is evaluated by atomic absorption
spectrophotometer method. A 5 g sample was dried and ashed in a
muffle furnace at 5500C temperature and the residue dissolved in 6 N,
1:1 hydrochloric acid. Iron and Zinc concentration of the sample was
estimated using the Atomic Absorption Spectrophotometry. Other
nutrient contents of malt were estimated using national food tables.
Each serving of fortified malt (25gms) contains 3.92mg of iron and
3.87mg of zinc when compare to unfortified malt (Iron – 1.29mgs
and zinc 0.69mg). [23]Study design:
Study design
This study is a randomized clinical trial. The trial will be performed
in tertiary care hospital in accordance with the Consolidated
Standards of Reporting Trials (CONSORT) statement. The protocol
is registered in the Clinical Trial RegistryCTRI/2022/11/047579.
Approval for the study was granted by Institute’s EthicsCommittees on Human Subject:
Study population:Infant with Non syndromic cleft lip and or
palate of 6 months of age.Inclusion criteria:
1) Cleft lip and or palate infants of age 6 months and above
attending the Out Patient Department2) Parents who give consent for the study.
Exclusion criteria:
• Infants with syndromes or with secondary deformities were
excluded.• Any congenital heart disease
The study population includes a total of 130 infants aged 6 months non syndromic cleft, who will be recruited into experimental group (n 65) or control group (n 65). A sample size of 65 infants per study group was required to detect an expected difference of 20% in increase Hb concentration between the baseline and endpoint results of intervention group, with statistical power of 95%.
Baseline Assessment:
Baseline data will be collected at the time of recruiting of
the eligible study participants. Data on socio-economic status,
anthropometric measurements, bio-chemical data, clinical history
and signs, and dietary history. Blood sample will be collected for Body
Iron store and S Zinc assay.Randomization and Allocation:
Eligible subjects will be randomly allocated into one of the two
groups according to a computer-generated randomisation list.
Study participants at the time of recruiting will be allotted one of the
following two groups;Group 1: Complementary food or fortified complementary food for a duration of 6 months.
Intervention:
Study participants will consume 25g of complementary food
per day for 6 months of intervention in addition to the habitual
complementary feeding regimen. The fortified complementary food
provided 75% of the daily recommended intake for iron and zinc so
that other complementary foods or breast milk could still contribute
to the DRI. Depending on the infant’s age and feeding behavior,
caregivers will be instructed to cook and feed 25 g of infant cereal.
Caregivers will be instructed to reconstitute 25g complementary
food with 150 ml of water and cook for 5 minutes to obtain a
puree consistency allowing to feed the infant cereal with a spoon.
Consumption of study malt amount (25gm) is constant and supports
growth metrics of infant as the requirement for 6-12months is same.
Along with this intervention, caregivers are encouraged to follow
Infant and Young Child Feeding practices for optimal growth.Post-baseline assessments will be conducted at midpoint (9
months of age) and at study end (12 months of age).
Primary outcome of the study is to see improvement in
body iron store as measured by Hemoglobin, S Ferritin, S Iron,
TIBC and S Zinc because the study malt is fortified with iron and
zinc. Anthropometric measurements will be measured at 9th and
12thmonth. Weight-for-age, length-for-age, weight-for-length, and
head circumference-for-age Z- scores will be calculated using WHO
reference data. Concomitant medications, including the use of iron
supplements based on a low Hb concentration during a study visit,
will be monitored throughout the study. Morbidity and safety will
be assessed from 1) a sickness questionnaire at baseline, midpoint,
and study end visit, 2) recording of adverse events (AEs) will be
collected during each visit for both groups. Nutrient intake will be
evaluated using a 24- hour dietary recall administered by a trained
dietitian to the infant’s parent or caregiver at baseline and all the
study visits for the both the groups. Breastmilk intake during the
24-hour dietary recall was assessed as frequency of breastmilk feeds.
The daily intake of energy, macronutrients (fat, carbohydrates, and
protein) and selected micronutrients (iron, and zinc) coming from
complementary food and regular diet will be calculated using Food
Composition Tables. Adherence to the dietary intervention will be
measured by subjective methods like 24 h dietary recall method and
food frequency questionnaire and objectively byimprovement in
weight gain, body iron store and ultimately eligibility for surgery.At
12th month, Neurodevelopment Assessment using the Bayley Scales
of Infant and Toddler Development Third Edition (Bayley-III) will
be assessed.
Data Management and Analysis:
A total of 130 infants with cleft will be screened for enrollment inthe Control group and Study group. During the intervention, maternal
and infant characteristics like ratio of boys to girls, mean birth weight,
gestational age, mode of delivery and breast feeding will be compared
between the two groups for any statistical differences. Students T
test will be applied for testing means. The socioeconomic status will
be studied. Iron status assessed by Hemoglobin, Serum Ferritin and
Serum Transferrin concentrations and Bayley-III scores between the
study group will be compared using analysis of covariance (ANOVA).
Chi square test will be applied for categorical data. At 12 months of
age growth outcomes in the two groups will be compared by similar
anthropometric Z-scores. Frequency of breastfeeding, energy and
nutrient intakes between the two study groups were compared by
independent t-test. With nutrition education and complementary
food provision, growth should be improved. Dietary intake will be
assessed by 24 hours recall as given by the care taker. With nutrition
support and education expect an improvement in dietary diversity
and in turn overall growth and development. Neurodevelopment
at 12 months of age will be assessed using the Bayley-III score for
both the groups. Many areas of child development are negatively
affected in infants with Cleft lip and/or palate. With improvement
in body iron stores and growth, we expect to see improvement in
neurodevelopment. Adverse events and concomitant medication will
be recorded during the visits.
Discussion
Malnutrition and anemia prevent many children with OFC from
receiving timely surgical care. Exclusive breastfeeding up to 6 months
of life is associated with better iron status in infants as it provides
highly bioavailable iron and reduces diarrheal diseases (and other
infections). Most infants with cleft do not receive breastmilk because
of feeding challenges. Use of formula feeds, unhygienic conditions
lead to repeated infection and hence malnutrition and anemia.
Nutritional inadequacies can be tackled through diet diversity, food
fortification and nutrition education. We assume, in our randomized
control study among infants with cleft lip palate aged 6 months who
will receive fortified complementary food for 6 months will have
better body iron stores at 12 months of age and lower rates of Iron
Deficiencies and Iron Deficiency Anemia than infants who will
receive the only complementary food. Homemade complementary
food often is low in iron concentration and bioavailability and do not
cover the high iron needs during rapid growth in infancy. Hence, the
need for fortification of complementary food to support the rapid
growth and development in infants
Conclusion
First 1000 days is the “critical window” for the promotion of
optimal growth, health, and cognitive development. Malnutrition in
infancy especially in infants with cleft can be attributed to feeding
challenges and inadequate infant feeding practices. To achieve optimal
growth in infants with cleft lip and palate, it is critical to implement
appropriate nutrition interventions and nutrition education to the
family. The goal is to provide the newborn with enough nourishment
before and after surgical intervention so that the infant recuperates
well.
