Children
are their nation’s future and it is the society’s responsibility to ensure
their healthy growth and development. Normal growth and development only when
we provide them with adequate nutrition and a safe environment to live in.
Amongst the few important markers of development, stunting is considered a
well-known marker of poor development. It affects millions of children globally
and is considered a major risk factor for paediatric morbidity and mortality. 1
According
to the Child Growth Standards set by the World Health Organisation, one in four
children under the age of five years are failing to grow along the optimum
trajectory. 1. This failure to grow is known as stunting, a term
given to impaired linear growth (length/height for age) in the early years of
life, which results in failure to reach a height by adulthood implied by
genetic potential. 1 It is also defined as malnutrition causing
impaired linear growth in the initial 2 years of life. 1
Nutritional
status is the major reason behind stunted growth but environmental risk factors
have also found to be associated with stunting. 1 In 2015, 5. 9
million children expired due to preventable causes of death and undernutrition
accounts for 45% of under 5 deaths. 3
Stunting
cannot be reversed easily and leads to physical and cognitive impairments.
These then undermine child’s educational attainment and ability to learn in
their lives later. 5
Globally,
persistent efforts have been made to decrease childhood stunting over the last
few years; however, there is high prevalence of stunting still in many low- and
middle-income countries. 5
Amongst
many researches, primary causes of childhood stunting remain continued exposure
to recurrent infections and inadequate nutritional intake, during the first
1000-days of life. 5
In addition, there are many risk factors
affecting growth and development that act independently of nutritional intake. 1
Day
by day, climatic challenges are worsening with their impacts extending far
beyond the environmental damage and are affecting global health in general. 2
According
to the current flood situation in Pakistan, children from affected areas are
bound to live in shelters. Researchers suggest that children who must live in
shelters could be more vulnerable to develop mental health problems due to
their exposure to various adverse environmental risk factors like poverty,
unstable home life and inadequate care.
Amongst
the many risk factors that have been studied for stunting, foodborne
mycotoxins, an inadequate sanitation, dirty home floors, sub-standard cooking
fuels, and lack of adequate local waste disposal were found topping the list. 1
Out
of many problems, the three pandemics—obesity, undernutrition, and climate
change—represent The Global Syndemic which has affected people worldwide. They
constitute a syndemic, or a synergy of epidemics due to their interaction with
each other. As a result, they produce complex sequelae and share common
underlying societal drivers.
Climatic
changes can also be considered a pandemic because of their disastrous effects
on the health of humans and the natural systems we depend on. 2
Environmental
factors were studied to correlate with nutritional status. 30.7%, 46.2% and
7.5% of children were found to be underweight, stunted and wasted respectively.
Open defecation, having access to unsafe water and children living in kuccha
houses were found to be more underweight. 3
Multiple
factors indicate a child’s poor diet quality, amongst which total and passive
screen time at 24 months of age were found to be important ones affecting
child’s mental health. 4
Another
interesting factor was children who had twice the risk of being stunted if they
had working mothers as compared to children with non-working mothers. 5
Amongst
the slum areas, maternal employment has been found to be associated with a
substantial increase in the odds of child stunting. This seems to arise in the
absence of adequate family support. Therefore, integrating appropriate
childcare support measures for low-income urban working mothers might be an effective
strategy to help reduce the prevalence of chronic undernutrition among slum
children. 5
Another
study revealed that amongst 819 extremely poor children, 325 (39.7%) were
stunted, 135 (16.5%) were underweight and 27 (3.3%) were wasted. In addition,
stunting and underweightness were negatively associated with developmental
skills. It was also observed that in extremely poor children, limited play
activities, limited child-to-child interactions and mother-child relationships
were negatively related mainly to gross motor and language performances of
children. 6
Undernutrition
and psychosocial factors were negatively related to the developmental outcomes
of children belonging to a poor socio-economic status. Hence, trying to
integrate home-based play-assisted developmental stimulation and nutritional
rehabilitation can help in normal development. 6
Maternal
education is an important factor in a child’s growth and development. Hence,
families with stronger family meal policies, where mothers did not work for pay
or were less educated, exhibited higher child “junk” food intake scores. 7
Low
parental education levels have been associated with poorer child diet quality
and increased child obesity. Similarly, maternal employment status (full time,
part-time or unemployed) and work hours affect children’s healthy lifestyles
and the family food environment to varying degrees. 7
Summarising it all, children are exposed to multiple risk factors for poor growth and development. This negative impact on their development and mental health results from the complex interaction between biological, psychological and environmental risk factors. Amongst all, the main factors influencing their development are the social and psychological environmental factors. Therefore, efforts regarding decreasing the cumulative risk effect are very important to ensure adequate growth and development in this population.
