CALCIUM INTAKE IN CHILDREN & ADOLESCENTS 2
Just like it does with other food components, calcium plays a significant role in the diet,
both for children and adults. It is rightly in order that any child, adolescent, or adult take a
recommended amount of calcium as this not only contributes to the overall well-being of the
body but also protects the body from the adverse effects that would otherwise result from
calcium deficit. This essay takes a look at the Australian dietary calcium intake, compares it to
the Nutrient Reference Values with specific focus on the Estimated Average Requirement, the
Recommended Daily Intake, and Upper Level, and further gives an evaluation of calcium’s
health implications.
In order to realize a good diet and consumption of recommended dosage of nutrients,
various countries have employed a number of assessment methods. These methods, in most
cases, are grouped into three, notably: Individual data, household data, and the national food
supply data (Fao.org1). Based on the individual data, Australian Health Survey further
synchronized into five distinct applicable sub-methods. The first being food record which is
alternatively known as food diary. In this case, the subject is expected to give a report of all
calcium foods consumed over a given span of time. The second sub-method in this case is the
24-hour recall of dietary in which the subject is expected to recount on the calcium-rich foods
consumed over the past 24 hours. Food frequency questionnaire is the third sub-method. In this
case, a structured listing of individual food or food grouping is maintained. The other two sub-
methods in this case are the questionnaires for food habit and history of diets. The second
method which, in essence, focuses on the household calcium consumption, is known as
household data. In this case, the data collected is used to compare the calcium consumption in
different families making up a community. The final method known as the national food supply

CALCIUM INTAKE IN CHILDREN & ADOLESCENTS 3
data, utilizes stuff like data of food disappearance and the balance sheet of food to give an
estimation of availability of calcium commodities nationally.
A closer view of Australia indicates that the vast majority do not attain the minimum
serves recommended for the five various groups of meals and as such, does not align with the
Australian Dietary Guidelines of the year 2013. As stated by Louise Gates, the ABS Director of
Health, hardly 10% of the Australian children and adults meet the recommended servings of
dairy products with only one out of every seven Australians consuming the right serving of lean
meat or its alternatives on a daily basis (Australian Bureau of Statistics2). Based on gender, a
higher number of female children and adolescents in Australia do not get the recommended
calcium serving as compared to their male counterparts. Australian Bureau of Statistics2 reports
that 51% male and 73% female Australians from age 2 and above do not get their Estimated
Average Requirement (EAR) serving for calcium. Based on this, ABS asserts that the males
consumed extra 0.3 calcium compared the females within the age bracket of 14-18. Whereas
ADG recommends 3 1
2 consumption of calcium by adolescents aged between 12-18 years, a
closer comparison of the consumption of the same indicates that 10% were able to consume
dairy products and their alternatives to meet the desired recommendations (Australian Bureau of
Statistics2). Comparatively, a 43% children aged between 2-8 years were able to meet the
Recommended Daily Intake (RDI) of calcium, and another 6.4% of those aged above 9 years
meeting the recommended serving too. Further statistics by ADG that groups the children and
adolescents into the ages of 2-3, 4-8, 9-11, 12-13, and 14-18 years indicates that 70.3%, 26.3%,
12.0%, 3.9%, and 2.5% of males respectively met the recommendation. This compares to 60.3%,
40.2%, 3.9%, 1.8%, and 0.5% of their female counterparts in the aforementioned age groups
(Australian Bureau of Statistics2). On average, 65% of children aged between 2-3 years were

CALCIUM INTAKE IN CHILDREN & ADOLESCENTS 4
reported to consume the recommended 1.5 servings of the products of dairy or their alternatives
on a daily basis. This is inclusive of the 20% that consumes more than 2.5 servings of the same
daily. 23% of the 35% who never met the recommended serving were reported to consume
amounts that were half a serving or less below the recommendation. From the data, it is also
clear that there is a general trend in reduced consumption of calcium as age increases. The table
below shows an analysis of calcium intake in boys and girls in the age bracket 14-18, the EAR,
RDI, and UL.

From the table above, it is quite evident that both boys and girls are taking insufficient calcium.
A number of literatures and peer-review journals have been developed to create
awareness on the effects of insufficient calcium in the diets of children and adolescents. One
such journal is known as the National Academies Press that addresses the behavior of eating in
children and adolescents as well as the heath concerns related to nutrition. The National Youth
Academies Press3 maintains that it is physical inactivity and poor diet observation that result into
imbalance, hence causing obesity. In addition to the National Youth Academies Press, Elsevier5
also gives evidence-based approach to the effects of calcium deficiency. It empirically addresses
the effects of supplementing short-term calcium both in children and adolescents. Finally,

CALCIUM INTAKE IN CHILDREN & ADOLESCENTS 5
Gateway8 crowns this list of peer-journals by laying emphasis on the importance of equipping
the caregivers with important skills giving the recommended servings of calcium to infants,
children and the adolescents. As a matter of fact, it also lays emphasis on the adverse effects that
come along with the inefficient serving of calcium to the aforementioned. These effects, in most
cases, are attached to the body skeleton which plays a significant role in the body.
Generally, calcium plays a significant role in bone formation as well as maintenance of
healthy bones. The improper consumption of the same warranties defects to the bones.
According to The National Youth Academies Press3, low supply of calcium to the body results
into degeneration of the bone tissues and low mass of the bone which eventually causes a
complex disorder known as Osteoporosis. DHHS4 justifies that a whooping 10 million
Americans suffer from this disorder. Loc cit., DHHS4 argues that owing to the fact that there is
an expected looming increase in the number of patients with this condition, those with hip
fracture are likely to triple by the year 2040. The argument on Osteoporosis given by The
National Youth Academies Press is similarly echoed by Esevier5 that claims that Phenylketonuria
patients have always experienced the occurrence of osteopenia risk and bone mineral density
reduction. Based on this assessment, the outcome was that upon the supplementation of calcium,
the levels of AD-SoS significantly increased (Esevier5, Porta et al.6 & Koura et al.7). As
contended by Gateway8, the human skeleton exhibits approximately 99% of the total calcium in
the body. In part, arguments are that lack of understanding of the regulatory requirements that
practically maintain the calcium level of serum may result into unintentional poor health
conditions in infants and children at different levels (National Institute of Health Consensus
Conference9). In support for this fact, the Institute of Medicine, Food and Nutrition Board10
emphasize that various dietary constituents as well as generic viability do affect the calcium

CALCIUM INTAKE IN CHILDREN & ADOLESCENTS 6
levels. This further justifies the fact that these levels need to be strictly observed as extremities in
this case could have severe effects.
In conclusion, calcium greatly plays an important role in the overall wellness of
children’s growth and development. As opposed to the Estimate Average Requirement, however,
a considerably larger number of Australian children and adolescents are under served with
calcium-rich food stuff. This is also justifiable with regard to the American statistics. Conditions
such as Osteoporosis, which result from calcium deficiency, could be greatly reduced if a close
observation is made to calcium consumptions at different levels of growth. The data giving the
variations on the uptake of calcium, as given by the Australian Health Survey, should be
considered as a true reflection of inefficient calcium consumption not only in Australia but also
the other parts of the world.
