‘70% north Indian women low in vitamin D, at high diabetes risk’

An inverse relationship exists between vitamin D levels and blood sugar levels indicating lower the vitamin D levels, the higher the blood sugar.

VITAMIN D

New Delhi, July 4: Despite adequate exposure to sunshine, nearly 70 per cent pre-diabetic women in north India are “deficient” in vitamin D, making them more vulnerable to the risk of developing Type-2 diabetes, finds a study.

Pre-diabetes is a condition in which blood sugar is high, but not high enough to be type 2 diabetes.

The findings showed that pre-diabetes women living in north India were 68.6 per cent vitamin D “deficient”, 26 per cent have “insufficient” levels, while only 5.5 per cent have “sufficient” levels of the vitamin.

“In India, there is a need to understand this as women have a propensity to be obese, develop metabolic syndrome, consequent hyperglycaemia and thereby be at the risk of diabetes. The pace at which women are moving from the pre-diabetic stage to the diabetic stage is alarming,” Anoop Misra, Chairman Fortis C-Doc, said in a statement.

“If this could be prevented by prescribing a cost effective vitamin D supplement, it would be truly amazing,” he added.

According to the researchers, an inverse relationship exists between vitamin D levels and blood sugar levels indicating lower the vitamin D levels, the higher the blood sugar.

It is because vitamin D may have a direct effect on the pancreatic beta cell function, thereby increasing insulin production.

“Previous studies had already established the link between the high prevalence of vitamin D deficiency and abdominal obesity. However, the relationship between vitamin D and the development of pre-diabetes, with a special focus on women, has remained obscure and unexplored,” Misra noted.

According to a recent report by India Spend, the country currently represents 49 per cent of the world’s diabetes burden, with an estimated 72 million cases in 2017, a figure expected to almost double to 134 million by 2025.

For the study, published in the British Medical Journal, the team included 797 women between the ages of 20 and 60.

The results indicated that women from lower socio-economic groups tend to have a higher vitamin deficiency that those from higher socio-economic groups.

Post-menopausal women who suffer from low calcium deposits in addition to low vitamin D deficiency were also found to be at a higher risk of bone damage than others.

Supplementation with vitamin D — present in foods such as milk, eggs, salmon, tuna, and mushroom — may prevent diabetes in India women, the researchers suggested.

A healthy diet, regular physical activity, maintaining a normal body weight and avoiding tobacco use are ways to prevent or delay the onset of Type-2 diabetes, the researchers said.

What is to be blamed for childhood cancer?

A team of researchers has thrown light on the community beliefs about what causes cancer in children, an area which remains understudied, finds a latest research.

“Few childhood cancers are attributed to genetics or environmental factors, so when children are diagnosed with cancer, families often wonder ‘why me/why us’?” said lead author Janine Vetsch, postdoctoral research candidate from UNSW Sydney in Australia.

For the study, the team examined the beliefs of more than 600 participants — parents and childhood cancer survivors — about the causes of childhood cancer, and compared them with beliefs of 510 members of the general population.

Findings, published in Acta Oncologica, revealed that more than seven out of 10 childhood cancer survivors and survivors’ parents believed that chance or bad luck caused the cancer.

This led to most parents and survivors seem to understand that there is nothing they could have done to prevent the cancer, according to Vetsch.

However, around one in five families did believe that environmental factors and genetics played a role, despite only limited available scientific evidence, results further showed.

“It looks like healthcare professionals are successfully helping most families arrive at that view,” said Vetsch.

Such views could lead to stigma. Hence, it is important to increase community knowledge of childhood cancer causes in general.

There is a need to encourage doctors to talk about the causes with affected families to address unhelpful misconceptions,” Vetsch suggested.

Does your dental floss contain toxic chemicals?

New York, Jan 9: Using Oral-B Glide dental floss could contribute to elevated levels of toxic chemicals that can lead to health problems, especially in women, including kidney and testicular cancer, high cholesterol, low birth weight, among others, says a study led by US-based Silent Spring Institute.

In the study, the team measured the presence of 11 different PFAS (per- and polyfluoroalkyl substances) — water- and grease-proof substances — in blood samples of 178 middle-aged women.

The findings, appearing in the Journal of Exposure Science and Environmental Epidemiology (JESEE), showed that women who flossed with Oral-B Glide tended to have higher levels of a type of PFAS called PFHxS (perfluorohexanesulfonic acid) in their body compared with those who did not.

“This is the first study to show that using dental floss containing PFAS is associated with a higher body burden of these toxic chemicals,” said lead author Katie Boronow, a scientist at the institute.

“The good news is, based on our findings, consumers can choose flosses that don’t contain PFAS,” she added.

Further, the team also tested 18 dental flosses (including three Glide products) for the presence of fluorine — a marker of PFAS, all of which tested positive for fluorine. The new findings are consistent with previous reports that Glide is manufactured using Teflon-like compounds.

In addition, the study also showed that women who frequently ate prepared food in coated cardboard containers, such as French fries or takeout, had elevated blood levels of PFAS chemicals.

“Overall, this study strengthens the evidence that consumer products are an important source of PFAS exposure,” Boronow said. “Restricting these chemicals from products should be a priority to reduce levels in people’s bodies.”

Other behaviours that were associated with higher PFAS levels included having stain-resistant carpet or furniture and living in a city served by a PFAS-contaminated drinking water supply.

How breastfeeding is linked to being a righty or lefty

Published

Breastfeeding

New York, Jan 9: Are you a leftie or a righty? The duration for which a child is breastfed may determine handedness or the dominant hand, says a research.

The study, from the University of Washington, suggests that the prevalence of left-handedness is lower among breastfed infants.

Children breastfed for longer than nine months were associated with the prevalence for righthandedness.

On the other hand, bottle fed infants were associated with left-handedness.

The reason could be because the region of the brain that controls handedness localises to one side of the brain.

Possibly, breastfeeding optimises this process towards becoming right or left-handed, the researchers explained.

“We think breastfeeding optimises the process the brain undergoes when solidifying handedness,” said Philippe Hujoel, a professor from the varsity.

“That’s important because it provides an independent line of evidence that breastfeeding may need to last six to nine months,” Hujoel added.

For the study, the researchers included 62,129 mother-child pairs.

The findings, published in the journal Laterality: Asymmetries of Body, Brain and Cognition, showed that breastfeeding for less than one month, one to six months, and more than six months, when compared to bottle feeding, was associated with a nine per cent, 15 per cent and 22 per cent decreased prevalence of non right-handedness, respectively.

However, the study does not imply that breastfeeding leads to right-handedness, Hujoel emphasised.

Handedness, whether it be right- or left-handed, is set early in fetal life and is at least partially determined by genetics, he noted.
