Moderate-to-vigorous exercise Lowers Preterm Birth Risk With Gestational Diabetes.







By Lori Solomon, HealthDay Reporter

MONDAY, Dec. 23, 2024 -- Moderate- to vigorous-intensity physical activity (MVPA) during pregnancy is inversely associated with preterm birth in women with gestational diabetes (GD), according to a study published online Dec. 19 in JAMA Network Open.

Wanglong Gou, Ph.D., from Westlake Laboratory of Life Sciences and Biomedicine in China, and colleagues examined the association of accelerometer-derived physical activity metrics and patterns with preterm birth among women with GD. The analysis included 1,427 women with GD with wearable accelerometer-derived physical activity data.

The researchers found an inverse relationship between an increase in MVPA and the fraction of physical activity energy expenditure derived from MVPA and preterm birth (odds ratio per 30 minutes, 0.64 and 0.69, respectively). The odds of preterm birth decreased progressively with increasing duration of MVPA per day, reaching a plateau at 74 minutes per day. The benefit was similar whether active MVPA (≥30 minutes per day) was concentrated into a few days or followed a more regular pattern.

"These findings provide key evidence for the health benefits of MVPA during pregnancy and lay the foundation for establishing physical activity guidelines for pregnant women with GD," the authors write.

  Learn How the NEW Nutrition Facts Label Can Help You Improve Your Health The US Food and Drug Administration (FDA) issued new regulations changing the  Nutrition Facts  label external  icon  on packaged foods. This is the first major change to the label since it was introduced in 1994. The changes are based on updated science, the most  recent dietary  recommendations, external  icon , and public input. Using the new label can help you choose foods for a healthy diet. The label will be required on all packaged foods made in the United States and imported from other countries. The new label is already appearing on packages. Most items will have the new label by January 1, 2021. What is changing? Calories & Fat Larger, darker letters make calories the easiest item to see on the new label. When it comes to health outcomes, the type of fat you eat matters more than the overall amount of fat. For this reason, the label will no longer show the per...

MUSCLES EXERCISING POWERS NEURON GROWTH AND REPAIR

  MUSCLES EXERCISING POWERS NEURON GROWTH AND REPAIR The findings suggest that biochemicals released during exercise and the physical effects of exercise could help heal nerves. Exercise is good for the body. Regular activity strengthens muscles and can strengthen bones, blood vessels, and the immune system. Now, MIT engineers have found that exercise can also have benefits at the level of individual neurons. They observed that muscles contract during exercise and release biochemical signals called myokines. In these muscle-generated signals, neurons grew four times further than neurons not exposed to myokines. These cellular-level experiments suggest that exercise can have a significant biochemical effect on nerve growth. Surprisingly, the researchers also found that neurons respond to the biochemical signals of exercise and its physical impacts. The team observed that when neurons are repeatedly pulled back and forth, similar to how muscles contract and expand during trainin...

CANNABIS, THE PHANTOM MENACE, MORE DANGEROUS THAN IMAGINED

  CANNABIS, THE PHANTOM MENACE, MORE DANGEROUS THAN IMAGINED  Scientists have known for some time that cannabis use has deleterious effects on health long-term. The evidence keeps piling up of how dangerous this drug can be.  A recent study conducted at McGill University showed how cannabis increases the risks of psychosis. These are just the latest concerns, as cannabis has also been implicated in increasing heart attacks and stroke risks, according to a study of 430,000 adults conducted by the American Heart Association. According to findings at McGill University, Young adults at risk of psychosis show reduced brain connectivity, a deficit that cannabis use appears to worsen. In the first-of-its-kind study, McGill University researchers detected a marked decrease in synaptic density -- the connections between neurons that enable brain communication -- in indivi...
