The continuing rise of lifestyle-related diseases and chronic disorders means that we need to take a fresh look at health and healthcare, and to remember that prevention is better than cure. The indicator is calculated following the Sullivan method which is widely used by experts across the world since the 1970’s. It is based on prevalence measures of the age specific proportion of population with and without disabilities and on mortality data. Its interest lies in its simplicity, the availability of its basic data and its independence of the size and age structure of the population. The health status of a population is inherently difficult to measure because it is often defined differently among individuals, populations, cultures, and even across time periods. The demographic measure of life expectancy has often been used as a measure of a nation’s health status because it is defined by a single vital characteristic of individuals and populations – death. However, the measure of life expectancy has limited utility as a gauge of a population’s health status because it does not provide an estimate of how healthy people are during their lifespan.
Many of the studies of health expectancy focus on measures such as physical impairment or disability in functional tasks or presence of a specific chronic disease. However,Â self-assessed health, being much more global and subjective in nature, can incorporate a variety of aspects of health including cognitive and emotional as well as physical status, and therefore provide insights into the needs of an aging society.
Our busy lifestyles can be hard on our family’s health. Rushing to and from school and work can make it hard to find time to be physically active. We can also slip into the habit of choosing unhealthy snacks and take-away foods or spending our free time watching TV or in front of the computer. Some people skip breakfast because they think it will help them lose weight. In fact, research shows that people who regularly eat breakfast are less likely to be overweight.
Long-term trials, following humans from early adulthood to death, are a rarity. I don’t see a human study of longevity as something that would be a fundable research programme,â€ says Mattison. Even if you start humans at 40 or 50 years old, you’re still looking at potentially 40 or 50 more years of study.â€ Plus, she adds, ensuring that extraneous factors – exercise, smoking, medical treatments, mental wellbeing – don’t influence the trial’s end results is near impossible for our socially and culturally complex species.
Most adults need to lose weight , and need to eat fewer calories to do this.
