It seems to be that sedentary is fast becoming a dirty word when it comes to a healthy extended life. The more we act to remove it from our lives that better off we will be.
Increased physical activity, not weight loss, gives individuals with coronary heart disease a longer lease on life, according to a new study conducted at the Norwegian University of Science and Technology (NTNU).
NTNU researchers have found that heart disease patients can gain weight without jeopardizing their health, but sitting in their recliner incurs significant health risks.
Weight loss seems to be associated with increased mortality for the participants in the study who were normal weight at baseline. The survey, which is an observational study based on data from HUNT (the Nord-Trøndelag Health Study), was recently published in the Journal of the American College of Cardiology (JACC).
Researcher Trine Moholdt in NTNU’s Department of Circulation and Medical Imaging collaborated on the study with cardiologist Carl J. Lavie at the John Ochsner Heart and Vascular Institute in New Orleans, and Javaid Nauman at NTNU.
They studied 3307 individuals (1038 women) with coronary heart disease from HUNT. Data from HUNT constitute Norway’s largest collection of health information about a population. A total of 120,000 people have consented to making their anonymized health information available for research, and nearly 80,000 individuals have released blood tests.
HUNT patients were examined in 1985, 1996 and 2007, and followed up to the end of 2014. The data from HUNT were compared with data from the Norwegian Cause of Death Registry.
During the 30-year period, 1493 of the participants died and 55 per cent of the deaths were due to cardiovascular disease.
“This study is important because we’ve been able to look at change over time, and not many studies have done that, so I am forever grateful to HUNT and the HUNT participants,” said Moholdt.
Exercise and live longer
The study revealed that people who are physically active live longer than those who are not. Sustained physical activity over time was associated with substantially lower mortality risk. Continue reading
