Men with diabetes and low testosterone levels at a greater risk of heart attacks

If you are a man and have diabetes, this news is for you. A new study has found that low testosterone levels in men with diabetes could increase their risk of heart disease . The study found that men who have low testosterone levels and type 2 diabetes are more likely to have atherosclerosis – a condition where plaque builds up in the arteries – than men who have diabetes and normal testosterone levels, the findings showed. ‘The results of our study advance our understanding of the interplay between low testosterone and cardiovascular disease in patients with diabetes,’ said study co-author Javier Mauricio Farias from Hospital Universitario Sanatorio Guemes in Argentina.

Atherosclerosis occurs when fats, cholesterol and other substances build up in and on the walls of the body’s arteries. This can restrict blood flow through the body’s blood vessels. The plaques also can burst and cause blood clots. ‘Our study indicates a strong association between low testosterone concentration and the severity of atherosclerotic plaques as well as other key atherosclerotic markers in middle-aged men with Type 2 diabetes,’ Farias added.  

The study involved 115 men with Type 2 diabetes. The participants were younger than age 70 and had no history of cardiovascular disease. The study found men who had low testosterone and Type 2 diabetes were six times more likely to have increased thickness of the carotid artery and endothelium dysfunction compared to men with normal serum testosterone levels. The findings appeared in the Journal of Clinical Endocrinology & Metabolism (JCEM).

Drinking soft drinks ages you 4 times faster

Love drinking sugar-sweetened, fizzy sodas? Well, you might just be doing a lot of damage to your health, especially your bones. According to a new study daily consumption of a 20-ounce sugar-sweetened soda is associated with 4.6 years of additional biological ageing – effects that are comparable to that of smoking – a new study has warned. Soda consumption might promote disease independently from its role in obesity, according to researchers from the University of California, San Francisco who found that drinking sugary drinks was associated with cell ageing. The study found that telomeres – the protective units of DNA that cap the ends of chromosomes in cells – were shorter in the white blood cells of survey participants who reported drinking more soda.

The length of telomeres within white blood cells – where it can most easily be measured – has previously been associated with human lifespan. Short telomeres also have been associated with the development of chronic diseases of ageing, including heart disease, diabetes, and some types of cancer.

‘Regular consumption of sugar-sweetened sodas might influence disease development, not only by straining the body’s metabolic control of sugars, but also through accelerated cellular ageing of tissues,’ said Elissa Epel, professor of psychiatry and senior author of the study. ‘This is the first demonstration that soda is associated with telomere shortness,’ Epel said. ‘This finding held regardless of age, race, income and education level. Telomere shortening starts long before disease onset. Further, although we only studied adults here, it is possible that soda consumption is associated with telomere shortening in children, as well,’ Epel said.

Based on the way telomere length shortens on average with chronological age, the UCSF researchers calculated that daily consumption of a 20-ounce soda was associated with 4.6 years of additional biological ageing. This effect on telomere length is comparable to the effect of smoking, or to the effect of regular exercise in the opposite, anti-ageing direction, according to UCSF postdoctoral fellow Cindy Leung, from the UCSF Center for Health and Community, lead author of the study. The authors cautioned that they only compared telomere length and sugar-sweetened soda consumption for each participant at a single time point, and that an association does not demonstrate causation.

The findings were published in the American Journal of Public Health.
