Less than six hours of sleep per day causes weight gain, type 2 diabetes (T2D) and obesity
A study by researchers at the Leeds Institute of Cardiovascular and Metabolic Medicine (LICAMM) and the School of Food Science and Nutrition, Leeds, United Kingdom shows increased risk of metabolic diseases, obesity or weight gain and to the development of high blood sugar levels or type 2 diabetes (T2D) with less than six hours of sleep. The study results show increased waist measurement by three cm among people who sleep on an average around six hours a night compared to those people who sleep on an average around nine hours of sleep a night. Researchers suggest seven to nine hours of night sleep per day for an adult individual.
Researchers found above results when they conducted a study involving 1,615 adults aged between 19 and 65 years. They collected details such as the number of sleep hours per day, food consumption, body weight, the circumference of waist, thyroid function, blood cholesterol, blood sugar or glucose and blood pressure from the participants. The study results also show reduced levels of HDL or "good" cholesterol among those participants who sleep for a shorter duration. Obesity is a risk factor for the development of multiple diseases including type 2 diabetes (T2D). But the study did not find any association between a less healthy diet and a less sleep.
The study not intended to assess chronic poor sleep over time and its associated diseases. Lead author of the study was Dr. Laura J. Hardie, a Reader in Molecular Epidemiology, the Leeds Institute of Cardiovascular and Metabolic Medicine (LICAMM), the University of Leeds. The study findings were published on July 27, 2017, in the journal PLOS One. Title of the article was "Longer sleep is associated with lower BMI and favorable metabolic profiles in UK adults: Findings from the National Diet and Nutrition Survey."
Higher risk of the development type 1 diabetes (T1D) in early term or early birth babies
A study by researchers at the Ben-Gurion University of the Negev (BGU), Israel shows the risk of the development of type 1 diabetes (T1D), obesity-related illnesses and shorter lifespan in "early term" or early birth babies. Delivery between 37 and 39 weeks is considered as "early term", preterm or early birth. But babies born between 39 and 41 weeks shows a less likely risk of the development of type 1 diabetes (T1D) compared to babies born either before 39 weeks or after 41 weeks.
The researchers analyzed general health outcomes and hospital visits of 171,000 full term delivery babies and 54,073 "early term" or early birth babies. Researchers found higher rates of type 1 diabetes (T1D) incidents in "early term" or early birth babies when they aged five years or older. They also found obesity or higher body mass index (BMI) when they grow and hospitalizations associated with endocrine and metabolic complications are common up to the age of 18 years.
Professor Eyal Sheiner, vice dean of Department of Obstetrics and Gynecology at the Soroka University Medical Center, Beersheba, Israel says early term pregnancies likely to be associated with following issues.
Authors of the study are Dr. Daniela Landau, Dr. Tamar Weinstock and Ruslan Sergienko from the Ben-Gurion University of the Negev (BGU), Israel. The study findings were published on August 7, 2017, in the American Journal of Obstetrics and Gynecology. Title of the article was "Evidence that children born at early term (37-38 6/7 weeks) are at increased risk for diabetes and obesity-related disorders."
