The adult generations of today are less healthy than their counterparts of previous generations

10.04.2013
Results from a large cohort study suggest that exposure to metabolic risks of cardiovascular disease is increasing

Sophia Antipolis, 10 April 2013. Despite their greater life expectancy, the adults of today are less "metabolically" healthy than their counterparts of previous generations. That's the conclusion of a large cohort study from the Netherlands which compared generational shifts in a range of well established metabolic risk factors for cardiovascular disease.

Assessing the trends, the investigators concluded that "the more recently born generations are doing worse", and warn "that the prevalence of metabolic risk factors and the lifelong exposure to them have increased and probably will continue to increase".

The study, reported today in the European Journal of Preventive Cardiology, analysed data on more than 6,000 individuals in the Doetinchem Cohort Study, which began in 1987 with follow-up examinations after six, 11, and 16 years.(1,2) The principal risk factors measured were body weight, blood pressure, total cholesterol levels (for hypercholesterolaemia) and levels of high-density lipoprotein (HDL) cholesterol, which is considered "protective".

The subjects were stratified by sex and generation at baseline into ten-year age groups (20, 30, 40, and 50 years); the follow-up analyses aimed to determine whether one generation had a different risk profile from a generation born ten years earlier - what the investigators called a "generation shift".

Results showed that the prevalence of overweight, obesity, and hypertension increased with age in all generations, but in general the more recently born generations had a higher prevalence of these risk factors than generations born ten years earlier. For example, 40% of the males who were in their 30s at baseline were classified as overweight; 11 years later the prevalence of overweight among the second generation of men in their 30s had increased to 52% (a statistically significant generational shift). In women these unfavourable changes in weight were only evident between the most recently born generations, in which the prevalence of obesity doubled in just 10 years.

Other findings from the study included:

Unfavourable (and statistically significant) generation shifts in hypertension in both sexes between every consecutive generation (except for the two most recently born generations of men).
Unfavourable generation shifts in diabetes between three of the four generations of men, but not of women.
No generation shifts for hypercholesterolaemia, although favourable shifts in HDL cholesterol were only observed between the oldest two generations.

As for the overall picture, and based on the evidence of a "clear" shift in the prevalence of overweight and hypertension, the investigators emphasise that "the more recently born adult generations are doing worse than their predecessors". Evidence to explain the changes is not clear, they add, but note studies reporting an increase in physical inactivity.

What do the findings mean for public health? First author Gerben Hulsegge from the Dutch National Institute for Public Health and the Environment emphasises the impact of obesity at a younger age. "For example," he explains, "the prevalence of obesity in our youngest generation of men and women at the mean age of 40 is similar to that of our oldest generation at the mean age of 55. This means that this younger generation is '15 years ahead' of the older generation and will be exposed to their obesity for a longer time. So our study firstly highlights the need for a healthy body weight - by encouraging increased physical activity and balanced diet, particularly among the younger generations.

"The findings also mean that, because the prevalence of smoking in high-income countries is decreasing, we are likely to see a shift in non-communicable disease from smoking-related diseases such as lung cancer to obesity-related diseases such as diabetes. This decrease in smoking prevalence and improved quality of health care are now important driving forces behind the greater life expectancy of younger generations, and it's likely that in the near future life expectancy will continue to rise - but it's also possible that in the more distant future, as a result of our current trends in obesity, the rate of increase in life expectancy may well slow down, although it's difficult to speculate about that."

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
