What is the Influence of Age on Health?

The average human lifespan is on the rise, with many individuals now expecting to live well into their 60s and beyond. Across the globe, populations are aging, with a significant increase in the percentage of seniors. By 2030, an estimated one in every six individuals worldwide will be aged 60 or older. This demographic shift is expected to continue, with the proportion of people aged 60 and over projected to increase from 1 billion in 2020 to 1.4 billion by 2050. Moreover, the global population of individuals aged 60 and above is anticipated to triple by 2050, reaching 2.1 billion. Over the same period, the population of those aged 80 and over is projected to triple as well, from 168 million to 426 million.

This phenomenon, known as population aging, refers to the trend of countries' age distributions skewing towards older age groups. Initially observed in high-income nations like Japan, where 30% of the population is already over 60, population aging is now most notable in low- and middle-income countries. By 2050, it's estimated that two-thirds of the world's population aged 60 and above will reside in these regions.

The Nature of Ageing

At the biological level, aging is primarily attributed to the accumulation of various types of molecular and cellular damage over time. This gradual process leads to a decline in both health and cognitive abilities, heightening the risk of developing severe illnesses and ultimately culminating in death. However, these changes aren't uniform or linear, and they exhibit only a weak correlation with chronological age. Age-related variations are not random occurrences. Alongside biological transformations, aging encompasses numerous life changes such as retirement, relocating to more suitable accommodations, and the loss of friends and companions

Hearing loss, cataracts, and refractive errors are common among the elderly, as are back and neck discomfort, osteoarthritis, COPD, diabetes, depression, and dementia. The likelihood of a person ageing and developing many coexisting conditions increases.

Geriatric syndromes are a collection of complicated health conditions that tend to appear in older people. Frailty, urine incontinence, falls, confusion, and pressure ulcers are all symptoms of underlying causes.

Influences on Ageing

The extended lifespan not only benefits individuals and their families but also enriches entire communities. With more time available, individuals can pursue long-held aspirations such as completing education, transitioning careers, or reigniting past hobbies. Moreover, the elderly contribute significantly to their communities and families. However, the pivotal factor determining the scope of these contributions remains health.
Studies indicate that the proportion of healthy years lived has remained relatively constant, suggesting that additional years often coincide with illness. The ability to engage in meaningful activities is largely contingent on enjoying good health and residing in supportive surroundings. If these extra years are spent in good health, individuals can maintain a similar level of functionality as their younger counterparts. Yet, if the majority of additional years are marred by physical and cognitive decline, both individuals and society face formidable challenges.

While certain disparities in elderly health can be attributed to inherent traits, the majority stem from environmental factors like living conditions and personal characteristics such as gender, ethnicity, or socioeconomic status. How individuals age is shaped not only by genetics and personality but also by early life circumstances, including prenatal and childhood experiences. Recognizing these influences is crucial for developing strategies to promote healthy aging and address disparities within aging populations.

Determine the Age

Once Excel processes the formula you input, it will normally display the calculated result. If you enter this formula into cell C2 without making any mistakes, you will get the age you requested in either years or months. These figures often occur without any explicit units. If you do the math and come up with the number 20, for instance, you can figure out if the individual is 20 years old or 20 months old, depending on the exact method you employed. Follow these instructions for each person whose age you want to determine.

Opportunities & Behaviours

Physical and social environments play a significant role in shaping opportunities, decisions, and health-related behaviors. Maintaining healthy habits throughout life, such as consuming a balanced diet, engaging in regular physical exercise, and avoiding tobacco use, not only reduces the risk of non-communicable diseases but also enhances physical and mental capabilities while delaying the need for care assistance

Living in socially and physically inclusive communities fosters the ability to pursue meaningful activities, even as functional limitations may arise with age. Accessible public transportation and easily navigable buildings contribute to such inclusive settings. When crafting public health responses to aging, it's essential to consider measures that promote recovery, adaptability, and psychological well-being, rather than solely focusing on mitigating age-related losses. This comprehensive approach is vital for supporting healthy aging and maximizing quality of life for older adults.


Physically and mentally, some 80-year-olds are on par with many 30-year-olds. Some people's abilities drastically deteriorate at significantly earlier ages. The diverse needs and experiences of the elderly must be taken into account by any effective public health response. Age-related differences are not coincidental. The opportunities and health-related behaviours of individuals are influenced to a considerable extent by the contexts in which they live. Personal traits such as our birth families, our sexes, and our ethnicities shape our interactions with our environments in ways that contribute to health disparities.

There's a common misconception that the elderly are helpless or a burden on society. These and other forms of ageism are problematic because they can lead to discrimination, shape policy decisions, and limit older adults' access to resources that support good ageing. There are both direct and indirect effects of globalisation, technical advances (especially in transportation and communication), urbanisation, migration, and shifting gender norms on the lives of the elderly. These expected trends are important to consider when formulating public health responses.
