  • Study suggests abdominal fat in the middle aged postmenopausal women drives cancer
  • Body fat distribution is more important as compared to the body weight, when talking about the risk of cancer in postmenopausal women
  • The best protection is to avoid central obesity 

Washington D.C. [USA], Sep 12, 2017: So if you never gave a thought to the idea of getting rid of that middle-age abdominal fat, ladies, this is the right time to start, as a recent study suggests, abdominal fat is a key factor in driving cancer for postmenopausal women.

It is important to understand the difference between the body weight and body fat distribution, since the latter is more important when talking about the risk of cancer in postmenopausal women, according to the study presented at the ESMO 2017 Congress in Madrid.

Women in this age group, who are more vulnerable to abdominal weight gain, are now left with a new spin on their weight management priorities, as a result of the findings, said Line Maersk Staunstrup, the study investigator.

“When assessing cancer risk, body mass index (BMI) and fat percentage may not be adequate measures as they fail to assess the distribution of fat mass,” she explained.

“Avoiding central obesity may confer the best protection,” she added.

The findings are from the prospective Epidemiologic Risk Factor study. The study, which is observational in nature, is a prospective cohort study designed to understand the age-related diseases in Danish, postmenopausal women, in a better way.

The study included 5,855 postmenopausal women, with the mean age being 71, who went through baseline dual-energy X-ray absorptiometry (DXA) scans to assess body fat and its composition, which have been followed for 12 years.

“The average elderly women can very much use this information, as it is known that the menopause transition initiates a shift in body fat towards the central trunk area. Therefore elderly women should be especially aware of their lifestyle when they approach the pre-menopause age,” said Mærsk Staunstrup.

“Clinicians can additionally use the information for a preventive conversation with women who are in higher risk of cancer. While clinicians have access to whole body DXA scanners at most hospitals, portable DXA scanners have become available on the commercial market and this may allow regional bone and fat scanning, however it may not be the most reliable for measuring central obesity,” she concluded.

Longer Exposure to Honking Traffic Makes You Obese

For the study, the researchers involved 3,796 adults and examined body mass index (BMI), waist circumference, body fat, central obesity and overweight

Are you obese or overweight? Blame long term exposure to blaring horns and other noise from road traffic, said researchers.

The study showed that a 10 decibel (dB) increase in mean noise level was associated with a 17 per cent increase in obesity.

“Our analysis shows that people exposed to the highest levels of traffic noise are at greater risk of being obese” said Maria Foraster, lead researcher from the Barcelona Institute for Global Health in Spain.

It could be because noise generates stress and affects our sleep. It alters hormone levels and increases blood pressure.

Moreover, among other effects, sleep disturbance deregulates glucose metabolism and alters the appetite, the researchers explained in the paper published in the journal Environment International.

“In the long term, these effects could give rise to chronic physiological alterations, which would explain the proven association between persistent exposure to traffic-related noise and cardiovascular disease or the more recently discovered associations with diabetes and obesity,” Foraster said.

“Our findings suggest that reducing traffic-related noise could also be a way of combating the obesity epidemic,” he noted.

For the study, the researchers involved 3,796 adults and examined body mass index (BMI), waist circumference, body fat, central obesity and overweight.

They also analysed exposure to noise generated by aircraft and railway traffic and found no significant associations except in the case of long-term exposure to railway noise, which was associated with a higher risk of overweight but not of obesity. (IANS)
