Calcium Deficiency among the Elderly
Calcium is one of the most important nutrients in the body and
significantly contributes to bone health. Hejazi points out that 99% of the
calcium requirement of the body is stored in the bones (1). Calcium requirement
in the body is dependent on age as those aged 50 years and above are
recommended to have 1200 mg/day as compared to about 1000 mg/day for men and women
with less than 50 years (2). Calcium is an essential nutrient that is needed throughout
the life cycle.
The process of aging is characterized by loss of appetite resulting in decreased
food intake. The decline in the ability to ingest an adequate amount of food,
as a consequence makes the elderly not able to meet their recommended nutrient
requirement (2). Among individuals aged 65 years and above calcium intake is insufficient leading to the decline of
serum calcium levels in the body to causes a series of consequences. First,
it causes increased secretion of parathyroid hormone (PTH) that results in the
resorption of bones and release of their content to the blood inhibiting the reduction
of the serum calcium level (1). The continuation of these phenomena decreases
BMD and increases the risk for osteoporosis.
Calcium deficiency causes a significant major health
issue among the elderly as it leads to osteoporosis. Osteoporosis is a systematic skeletal disease characterized by the loss
of bone mass density (BMD) and damage to the microstructure of bone tissue
leading to bone susceptibility and risk of fracture. In Australia, osteoporosis
is a health condition affecting approximately 4% of the population (3).
The elderly require calcium as their skeleton loses it due to age (1).
Most women lose more calcium from their bones in the 5-10 years around the age
of menopause. However, both men and women lose bone mass as they grow older and
need to make sure that they get enough calcium in their diet to offset the
losses. Older patients need to understand that a high diet of calcium cannot
reverse age-related bone loss but can slow down the process (2).
The impacts of Calcium Deficiency
Osteoporosis is a major healthcare issue specifically affecting the
elderly as it is an issue of concern as; The condition
causes morbidity and mortality among older people (1). It also imposes a
profound financial burden on the healthcare system every year. Today,
osteoporosis is an epidemic in some societies with the rapid growth of elderly
people (1).

The statistics confirms that women have higher chances of suffering from
osteoporosis than men aged 75 years and above.
Risk factors
How Lifestyle can affect bone strength
· High salt-diet.
· More than 6 drinks per day of caffeine-containing drinks such as coffee,
cola, or energy drinks.
· Excessive alcohol intake (4).
· Very low body weight.
· Smoking.
· Very high intake of fibre (More than 50 g per day from wheat bran).
· Low levels of physical activity and low levels of vitamin D
Role of calcium in the body
i.
Calcium plays a vital role in strengthening bones and
teeth,
ii.
Calcium regulates muscle functioning such as vascular
contraction and relaxation (5).
iii.
Calcium plays a role in regulating heart functioning.
iv.
Calcium plays a significant role in blood clotting.
v.
Calcium helps in the transmission of nervous system
messages (5).
vi.
Calcium aids in enzyme function.
Dietary sources of Calcium
i.
Dairy products account for a mere 40% of calcium
intake largely due to the popularity of dietary supplements and the declining
intake of cow’s milk (6). Milk and Milk products such as yogurt, cheese, and
buttermilk. For instance, one cup of milk, a 200g tub of yogurt, or 200 ml of
calcium-fortified soymilk provides around 300 mg of calcium.
Besides, calcium-fortified milk can provide large amounts of calcium in a
smaller volume of milk ranging from 280 mg to 400 mg per 200 ml of milk.
ii.
Leafy green vegetables such as broccoli, collards
(cabbage family), bok choy, Chinese cabbage, and spinach (7). For instance, one
cup of cooked spinach contains 100mg although about 5% of this may be absorbed.
This is due to the high concentration of oxalate, a compound in spinach that
reduces calcium absorption. In contrast, one cup of
cooked broccoli contains about 45 mg of calcium but the absorption is higher at
around 50-60%.
iii.
Other food types rich in calcium include soy and tofu,
fish, nuts, and seeds such as almonds where 15 almonds contain 40 mg of
calcium. Sardines and canned salmons and their bones are included as the fish
types that yield adequate calcium (7). For instance, half a cup of canned
salmon contains 402mg of calcium.
iv.
Besides, calcium-fortified foods like breakfast
cereals, fruit juices, bread, and some plant-based kinds of milk also
supplement calcium intake in the body.
Recommendations
Good nutrition plays a significant role in osteoporosis prevention and
treatment. This can be achieved through several interventions.
I.
Maintenance of an adequate protein intake is important
in the preservation of musculoskeletal function in men and women over 50 years
of age (8).
II.
The use of protein supplements in patients with hip
fracture help in lessening bone loss, reducing the risk of infection, diminishing
the length of hospital stay, and increases in functional recovery. The endorsed
protein intake is 1.2g/kg daily (8).
III.
Undertaking lifestyle modifications within the
population-based strategies can help in having an adequate intake of calcium
and sufficient intake of vitamin D such as proper dieting and sun exposure.
IV.
In instances of deplorable state, the elderly can take
a minimum dose of 400 IU of vitamin D which is desirable in the blood levels at
a rate of 30-50 ng/mL.
V.
The endorsed calcium intake is 1000-1200 mg daily with
a preferable intake through dieting. However, supplementation can be provided
not to exceed 500-600 mg per dose (2).
VI.
Additionally, exercises with weight, balance, and
resistance load are recommended to help improve mobility, strength, and
physical performance as a way of reducing the risk of fragility fracture
through the prevention of falls which can be attained through supervision such
as physical therapy.

Absolutely! Calcium plays a pivotal role in bone health, especially as we age. The recommended intake varies with age, emphasizing its significance across the life cycle. This insight aligns well with the depth of analysis expected in CIPD assignment level 5.
I recently learned about calcium deficiency among the elderly and how crucial it is for their bone health. It's alarming to see how many seniors struggle with this issue. As someone interested in tech, I think it’s important for us to support local companies that distribute essential health products, like a microsoft distributor in dubai, to help improve our community's well-being.
5/5
Calcium deficiency is a significant concern for the elderly, affecting bone health and overall well-being. Calcium supplements can play a vital role in bridging the gap, supporting stronger bones and reducing the risk of osteoporosis. They are an excellent addition to a balanced diet for seniors.
