Walking faster could make you live longer

Walking faster could make you live longer, a study led by the University of Sydney suggests. Walking at an average pace was found to be associated with a 20 percent risk reduction for all-cause mortality compared with walking at a slow pace, while walking at a brisk or fast pace was associated with a risk reduction of 24 percent.

A similar result was found for risk of cardiovascular disease mortality, with a reduction of 24 percent walking at an average pace and 21 percent walking at a brisk or fast pace, compared to walking at a slow pace.

“A fast pace is generally five to seven kilometers per hour, but it really depends on a walker’s fitness levels; an alternative indicator is to walk at a pace that makes you slightly out of breath or sweaty when sustained,” lead author Professor Emmanuel Stamatakis explained in the findings published in a special issue of the British Journal of Sports Medicine.

The researchers sought to determine the associations between walking pace with all-cause, cardiovascular disease and cancer mortality.

The protective effects of walking pace were also found to be more pronounced in older age groups. Average pace walkers aged 60 years or over experienced a 46 percent reduction in risk of death from cardiovascular causes, and fast pace walkers a 53 percent reduction.

“Walking pace is associated with all-cause mortality risk, but its specific role – independent from the total physical activity a person undertakes – has received little attention until now,” Professor Stamatakis said.

“While sex and body mass index did not appear to influence outcomes, walking at an average or fast pace was associated with a significantly reduced risk of all-cause mortality and cardiovascular disease. There was no evidence to suggest pace had a significant influence on cancer mortality however.”

In light of the findings, the research team is calling for walking pace to be emphasised in public health messages.
“Separating the effect of one specific aspect of physical activity and understanding its potentially causal association with risk of premature death is complex,” Professor Stamatakis said.

“Assuming our results reflect cause and effect, these analyses suggest that increasing walking pace may be a straightforward way for people to improve heart health and risk for premature mortality – providing a simple message for public health campaigns to promote.

Diabetes drug might ease heart failure risk

A new research has showed that the diabetes drug Farxiga might do double-duty for patients, helping to ward off another killer, heart failure.

According to the findings were published in the New England Journal of Medicine to coincide with their presentation at the annual meeting of the American Heart Association in Chicago, Type 2 diabetics who took Farxiga saw their odds of hospitalization for heart failure drop by 27 percent compared to those who took a placebo.

Farxiga is a type of drug called a SGLT2 inhibitor. The compound is called dapagliflozin.

The study included more than 17,000 type 2 diabetes patients aged 40 and older. Nearly 7,000 had heart disease and more than 10,000 had numerous risk factors for heart disease, Wiviott’s group said.

Patients were randomly assigned to take a dummy placebo pill or 10 milligrams of Farxiga each day.

“When it comes to helping our patients control and manage blood glucose, the ‘how’ appears to be as important [as] the ‘how much,” said study author Dr Stephen Wiviott, a cardiovascular medicine specialist at Brigham and Women’s Hospital in Boston.

“When choosing a therapy, trial results like these can help us make an informed decision about what treatments are not only safe and effective for lowering blood glucose but can also reduce risk of heart and kidney complications,” Wiviott said in a hospital news release.

Taking the drug did not reduce the risk of heart attack, stroke and cardiovascular-related death, the research team noted. However, patients who took the drug did see healthy declines in their blood sugar levels, plus an added bonus: a 27 percent decrease in their risk of hospitalization for heart failure.

Their risk of kidney failure and death from kidney failure also fell, researchers noted.

Two other recent studies of this class of drugs show that they “robustly and consistently improve heart and kidney outcomes in a broad population of patients with diabetes,” Wiviott noted.
