The Risk Of Type 2 Diabetes And Heart Disease With A 2-week Sedentary Behavior
A study at the University of Liverpool, the United Kingdom shows a decrease in metabolic health and the muscle mass with a just two-week break (or a holiday) from daily physical exercise. A two-week break from daily exercise may lead to chronic diseases such as type 2 diabetes (T2D) and heart diseases.
This study shows the importance of daily physical activity and the adverse health consequence with a sedentary behavior when an individual takes a 14-day break from daily physical activity.
A study was conducted on 28 individuals with an average age of 25 years and 25kg/m2 of BMI to find out the risk factors to the chronic diseases when a person takes a 14-day break from daily physical activity. The investigators have observed a change in the body composition, decrease in cardio-respiratory fitness and the skeletal muscle mass and an increase in the total fat in the central area.
The change in the total body fat and the accumulation of fat in the central area of the body are the major risk factor for the development of chronic diseases.
The author of the study was Dr. Kelly Bowden-Davies and the leader of the study was Dr. Dan Cuthbertson, the University of Liverpool, UK. The study was presented at the European Congress on Obesity (ECO2017), between May 17 and 20, 2017 in Porto, Portugal. Title of the article is "Short-term decreased physical activity with increased sedentary behaviour causes metabolic derangements and altered body composition: effects in individuals with and without a first-degree relative with type 2 diabetes."
Increase In The Risk Of Gestational Diabetes With An Increase In Outdoor Temperature
According to the Centers for Disease Control and Prevention (CDC), 9.2 percent of pregnant women are affected by gestational diabetes (GD) in the United States in 2014.
An earlier study shows an improvement in insulin sensitivity when the body is exposed to the cold temperature as the body produces more heat to maintain body temperature. The cold weather can improve the insulin sensitivity of an individual as the brown adipose tissue will play a protective role.
An observational study by the researchers at the Mount Sinai Hospital, the St Michael's Hospital, the Institute for Clinical Evaluative Sciences (ICES) and the University of Toronto shows an increase in the risk of gestational diabetes (GD) with hot weather (air temperature). The authors say that the number of women affected by gestational diabetes (GD) may continue to rise due to the consequence of global warming.
The researchers have examined 555,911 deliveries of 396,828 women with an average age of 31 years for 12 years (between 2002 and 2014). The researchers considered a temperature of less than or equal to 10℃ as cold temperature and an average temperature of 24℃ as hot temperature. Gestational diabetes (GD) screening was done after exposing the pregnant women for 30 days at either hot or cold temperatures.
The researchers have found maternal gestational diabetes in 4.6 percent of pregnant women when exposed to cold temperature and in 7.7 percent of pregnant women when exposed to hot temperature. The study shows a six to nine percent increase in gestational diabetes (GD) with every 10℃ increase in outdoor (atmospheric) temperature. A similar trend was found in the mother of two babies with a difference in temperatures.
The researchers have observed a direct association between the risk of gestational diabetes (GD) and outdoor temperature in 400,000 pregnant women.
The lead author of the study was Dr. Gillian Booth, a researcher at St Michael's and ICES and the study was published on May 15, 2017, in the Canadian Medical Association Journal (CMAJ). Title of the article is "Influence of environmental temperature on risk of gestational diabetes."
