Are you ready? What you need to know about ageing


Determinants of healthy ageing

1. Healthy ageing is linked to health in earlier stages of life

Undernutrition in the womb, for example, may increase the risk of disease in adult life, such as circulatory diseases and diabetes. Respiratory infections in childhood may increase the risk of chronic bronchitis in adult life. Obese, or overweight, adolescents run the risk of developing chronic diseases, such as diabetes, circulatory disease, cancer, respiratory and musculo-skeletal disorders, in adult life.

2. Yet, how well we age depends on many factors

The functional capacity of an individual's biological system increases during the first years of life, reaches its peak in early adulthood and naturally declines thereafter. The rate of decline is determined, at least in part, by our behaviours and exposures across the whole life course. These include what we eat, how physically active we are and our exposure to health risks such as those caused by smoking, harmful consumption of alcohol, or exposure to toxic substances.
