In this extract taken from a Geneva Association newsletter, Mr Florian Boecker of PartnerRe reviews lifestyle risk trends and their dynamic and varied impact on Life and Health (re)insurance.
 
We all hope (and in many cases, expect) to live a long, healthy life. Over the last century, disease and accident prevention measures and medical progress have massively improved our chances of doing just that. Indeed, the world average life expectancy at birth more than doubled over this period, increasing from 31 years at the beginning of the 20th century to 68 years in 2013 (although there is still a large contrast between developed countries, where a newborn can expect to live well beyond its 80th birthday, and the poorest countries where it will struggle to reach its 50th). Most of this progress in life expectancy is due to the successful fight against infectious diseases, better treatment of cardiovascular disease and a reduction in accidents and injuries. 
   However, we are not doing as well as we could do in minimising our risk of disease and injury when the contributory cause relates to the way in which we (in the main, choose to) live our lives. Known to (re)insurers as “Lifestyle Risk Factors”, smoking, drinking, drugs, poor dietary habits and lack of physical exercise, for example, all have a significant negative influence on our health. 
   To better understand the impact of lifestyle risk factors, we can look at the disability-adjusted life years (DALYs) concept, a measure of the “burden of disease”. This measure is defined as the number of healthy years lost due to both sickness and premature mortality, compared to an ideal situation where everyone in the population lives healthily to an advanced age. 
   Splitting DALYs by cause indicates where the major health issues lie in a population. As Figure 1 shows, DALYs directly linked to lifestyle risk factors account for more than 75% of total DALYs in developed countries. This demonstrates just how important it is to monitor and understand the various lifestyle related risk factors and their respective evolution. 
 
Dalys in developed countries in 2010
 
Over-sized vs under-sized
Weight related issues are the biggest contributor to DALYs in developed countries (Figure 1), with problems at both ends of the weight spectrum. 
   At one end of the scale, a rapidly increasing number of people, especially in developed countries, now qualify as obese, ie have a body mass index (BMI) of 30 or higher. Although BMI is an imperfect measure for the adequacy of a person’s weight, it is still widely used and is considered sufficient in the context of this article. Of particular concern is the fact that the highly obese subpopulation (persons with a BMI of 35 or higher) is growing even more rapidly than the “normally obese” group. 
   While we will have to live with the consequences of increasing obesity, including the financial strain on health systems, there is at the same time some positive news. The recent, and hopefully sustainable, trend towards personal fitness and health programmes could lead to a partial reversal of the obesity trend, although the effect may be selective within certain subgroups. Technology, primarily in the form of wearable fitness trackers and health apps, has the potential to play a crucial role in this development by encouraging users to enhance their activity and fitness levels. 
   At the other end of the scale, being underweight is also a major health concern. In terms of excess mortality, having a BMI of 15 is equivalent to being extremely obese with a BMI of 40. Contributing to these figures, severe eating disorders such as anorexia nervosa and bulimia nervosa have the highest mortality rates of all major mental illnesses. 
 
Still cool to smoke?
The use of tobacco increased continuously throughout the first three quarters of the last century, proliferated during the major wars of this period and supported by aggressive marketing and PR campaigns by the tobacco industry. 
   Since the causal link between smoking and certain types of cancers has been established, the attitude of society towards tobacco consumption has changed, leading to the introduction of a broad variety of measures to discourage smoking. As a result, the prevalence of smoking around the world has significantly decreased. 
   Relatively recently, a new trend has emerged: e-cigarettes became very popular within just a few years of their introduction. In terms of health risk, the jury is still very much out on the associated long-term health effects of e-cigarettes and many are concerned by their potential to attract non-smokers. There is also anecdotal evidence that e-cigarettes are being used to consume illicit substances such as hashish oil. 
   They are, however, overall considered by many researchers to be the “healthier choice” because they lack most of the toxic ingredients that are present in tobacco, delivering mainly just nicotine (plus propylene glycol/glycerine) in vapour form. 
 
A tipple too many
Alcohol has a multi-faceted, predominantly negative impact on health. Excessive “binge” drinking and chronic alcohol consumption have slightly different effects, respectively linked to injuries and poisoning vs severe diseases including liver cirrhosis and cancers. 
   The trends in alcohol consumption vary significantly by country (see Figure 2). 
 
 
In developed countries with an established “drinking culture”, a person aged 15 years and over consumes on average 11-12 litres of pure alcohol per year. This equates to approximately three small (0.2 litre) beers per person per day – every person, every day! Although this number is alarming, the good news is that consumption is generally decreasing in most of those countries. Recent statistics from the UK, for example, indicates that binge drinking levels are falling. However, some subpopulations, such as older men, are drinking more. 
   Developing countries, for example China, India and Brazil, are experiencing an increase in alcohol consumption, but from a lower level compared to developed countries. This trend is mainly driven by a westernisation of lifestyle in combination with the increased affordability and availability of alcoholic beverages. 
   These two country groups are framed on the one side by Eastern European countries, which in general display very high alcohol consumption, and on the other by Islamic countries with negligible drinking levels. Both extremes indicate the importance of social acceptance of alcohol consumption as a determinant of its prevalence – an effect that we see to varying extents for all major lifestyle risk factors.
 
Insurance in a world of fast-changing lifestyles
In a world which has overcome many of the “big killers” of the past, lifestyle choices have now become the dominant factor that determines the likelihood of a long and healthy life. They are therefore of great importance not just to the individual and to society in general, but also to Life and Health (re)insurers. 
   The good news is that substantial progress is being made; smoking and alcohol consumption are on the decline in many countries and personal fitness is increasing in popularity, all of which will have a positive impact on health and mortality. However, there are worrying, negative developments in some areas, such as obesity, and lifestyle risk is clearly a dynamic area with subgroups that are at substantially higher risk irrespective of positive overall trends. 
 
Wearables and predictive underwriting
Looking into the future, technology, especially better data analytics, is set to lead to new life and health insurance products that are both very attractive for the policyholders while at the same time protecting the (re)insurers against anti-selection. 
   Predictive underwriting will make insurance purchases more convenient for the policyholder. Wearables offer the opportunity to monitor and positively influence the behaviour of individuals and could be used to provide flexible, highly customised insurance protection at a comparably low price. These devices may actually become the Life and Health equivalent to telematics. In addition, previously uninsurable subpopulations, such as HIV positive individuals, are now already able to access affordable life insurance cover due to advances in the treatment of this infection and a greatly enhanced comprehension of the risks associated with it. 
   An area where improvement is needed relates to the speed at which the (re)insurance industry responds to changing trends, a good example being e-cigarettes which may have gone through most of their “popularity cycle” before the industry fully incorporated this phenomenon into underwriting. 
   As an industry, we need to better understand lifestyle risks and their impact on our customers. For better or worse, they are the key group of risk factors in Life and Health (re)insurance, they are dynamic and they can be influenced.
