Weight cycling linked to increased sleep problems in women

2021-05-20
(Press-News.org) May 20, 2021 - Women with a history of weight cycling - losing and regaining 10 pounds or more, even once - have increased rates of insomnia and other sleep problems, reports a study in The Journal of Cardiovascular Nursing, official journal of the Preventive Cardiovascular Nurses Association. The journal is published in the Lippincott portfolio by Wolters Kluwer.

"History of weight cycling was prospectively associated with several measures of poor sleep, including short sleep duration, worse sleep quality, greater insomnia, greater sleep disturbances, and greater daytime dysfunction among diverse US women across various life stages," according to the new research by Brooke Aggarwal, EdD, MS, FAHA, of Columbia University Vagelos College of Physicians and Surgeons, New York, and colleagues.

Weight cycling predicts shorter, poorer-quality sleep and higher sleep apnea risk The researchers analyzed data on 506 women, average age 37 years, enrolled in an ongoing American Heart Association-funded "Go Red for Women" research project. The women represented every stage of adult life, including childbearing, premenopausal, menopausal, and postmenopausal. About 60 percent of the women identified themselves as a racial/ethnic minority.

Seventy-two percent of the women reported one or more episodes of weight cycling, defined as losing or gaining at least 10 pounds (excluding pregnancy). History of weight cycling was evaluated for associations with a wide range of sleep problems, both at the time of study entry and at a one-year follow-up visit. The analyses adjusted for other factors known to affect women's weight history, including pregnancy history and menopausal status.

At both times, sleep problems were more likely for women with any history of weight cycling. Each additional episode of weight cycling was associated with shorter sleep time, poorer sleep quality, longer time to falling asleep, more severe insomnia, more sleep disturbances, less-efficient sleep, and more frequent use of sleep medications.

History of weight cycling also predicted an increased risk of sleep problems at follow-up. After adjustment for other factors, women with even a single episode of weight cycling were at higher risk of shorter sleep duration (less than seven hours), lower scores for sleep quality and efficiency, and longer time to falling asleep (about half an hour or more).

Women with episodes of weight cycling were also five times more likely to score in the high-risk range for developing obstructive sleep apnea (OSA). Patients with OSA have interruptions or other abnormalities of breathing during sleep. Obstructive sleep apnea is an important risk factor for serious health problems, including heart disease and stroke.

Being overweight or obese is a known risk factor for sleep problems. In previous studies in their "Go Red for Women" research cohort at Columbia University, Dr. Aggarwal and colleagues found that women with a history of weight cycling had increased odds of poor cardiovascular health. The relationship between weight cycling and sleep problems may be "bidirectional" - reflecting the "intricate interplay" between sleep and weight loss/weight maintenance.

The researchers emphasize the need for further studies of how body weight changes across the life span may affect sleep, in men as well as women and across racial/ethnic groups. In the meantime, asking women about their history of weight cycling might be helpful in identifying their risk for sleep problems, including OSA.

The findings also suggest that maintaining a stable body weight over time might promote better quality sleep. Dr. Aggarwal and coauthors conclude, "Future research can potentially inform more targeted weight maintenance interventions for sleep health and cardiovascular health promotion."

Airborne radar reveals groundwater beneath glacier

Airborne radar reveals groundwater beneath glacier
2021-05-20
Melting glaciers and polar ice sheets are among the dominant sources of sea-level rise, yet until now, the water beneath them has remained hidden from airborne ice-penetrating radar. With the detection of groundwater beneath Hiawatha Glacier in Greenland, researchers have opened the possibility that water can be identified under other glaciers from the air at a continental scale and help improve sea-level rise projections. The presence of water beneath ice sheets is a critical component currently missing from glacial melt scenarios that may greatly impact how quickly seas rise - for example, by enabling big chunks of ice to calve ...

Forensic memory detection tests less effective in older adults

2021-05-20
New research led by the University of Kent's School of Psychology has found that some brain activity methods used to detect incriminating memories do not work accurately in older adults. Findings show that concealed information tests relying on electrical activity of the brain (electroencephalography [EEG]) are ineffective in older adults because of changes to recognition-related brain activity that occurs with aging. EEG-based forensic memory detection is based on the logic that guilty suspects will hold incriminating knowledge about crimes they have committed, and therefore their brains will elicit a recognition response ...

The entire genome from Peştera Muierii 1 sequenced

The entire genome from Peştera Muierii 1 sequenced
2021-05-20
For the first time, researchers have successfully sequenced the entire genome from the skull of Peştera Muierii 1, a woman who lived in today's Romania 35,000 years ago. Her high genetic diversity shows that the out of Africa migration was not the great bottleneck in human development but rather this occurred during and after the most recent Ice Age. This is the finding of a new study led by Mattias Jakobsson at Uppsala University and being published in Current Biology. "She is a bit more like modern-day Europeans than the individuals in Europe 5,000 years earlier, but the difference is much less than we had thought. We can see that she is not a direct ancestor of modern Europeans, but she is a predecessor of the hunter-gathers that lived in Europe until the end of the last ...

Newly identified antibody can be targeted by HIV vaccines

2021-05-20
DURHAM, N.C. - A newly identified group of antibodies that binds to a coating of sugars on the outer shell of HIV is effective in neutralizing the virus and points to a novel vaccine approach that could also potentially be used against SARS-CoV-2 and fungal pathogens, researchers at the Duke Human Vaccine Institute report. In a study appearing online May 20 in the journal Cell, the researchers describe an immune cell found in both monkeys and humans that produces a unique type of anti-glycan antibody. This newly described antibody has the ability to attach ...

Survival of migrating juvenile salmon depends on stream flow thresholds

Survival of migrating juvenile salmon depends on stream flow thresholds
2021-05-20
Juvenile salmon migrating to the sea in the Sacramento River face a gauntlet of hazards in an environment drastically modified by humans, especially with respect to historical patterns of stream flow. Many studies have shown that survival rates of juvenile salmon improve as the amount of water flowing downstream increases, but "more is better" is not a useful guideline for agencies managing competing demands for the available water. Now fisheries scientists have identified key thresholds in the relationship between stream flow and salmon survival that can serve as actionable targets for managing water resources in the Sacramento River. The new analysis, published May 19 in Ecosphere, revealed nonlinear ...

Understanding light-activated proteins in order to improve them

Understanding light-activated proteins in order to improve them
2021-05-20
Today, proteins that can be controlled with light are a widely used tool in research to specifically switch certain functions on and off in living organisms. Channelrhodopsins are often used for the technique known as optogenetics: When exposed to light, these proteins open a pore in the cell membrane through which ions can flow in; this is how nerve cells can be activated. A team from the Centre for Protein Diagnostics (PRODI) at Ruhr-Universität Bochum has now used spectroscopy to discover a universal functional mechanism of channelrhodopsins that determines their efficiency as a channel and thus as an optogenetic tool. The researchers led by Professor Klaus ...

Microfluidic technologies have seen great advances over the past few decades in addressing applications such as biochemical analysis, pharmaceutical development, and point-of-care diagnostics. Miniaturization of biochemical operations performed on lab-on-a-chip microfluidic platforms benefit from reduced sample, reagent, and waste volumes, as well as increased parallelization and automation. This allows for more cost-effective operations along with higher throughput and sensitivity for faster and more efficient sample analysis and detection. Optoelectrowetting (OEW) is a digital optofluidic technology that is based on the principles of light-controlled electrowetting and enables ...

The viruses in our genes: When activated, they damage brain development

The viruses in our genes: When activated, they damage brain development
2021-05-20
Since our ancestors infected themselves with retroviruses millions of years ago, we have carried elements of these viruses in our genes - known as human endogenous retroviruses, or HERVs for short. These viral elements have lost their ability to replicate and infect during evolution, but are an integral part of our genetic makeup. In fact, humans possess five times more HERVs in non-coding parts than coding genes. So far, strong focus has been devoted to the correlation of HERVs and the onset or progression of diseases. This is why HERV expression has been studied in samples of pathological origin. Although important, these studies ...

How plants leave behind their parents' genomic baggage

How plants leave behind their parents genomic baggage
2021-05-20
Passing down a healthy genome is a critical part of creating viable offspring. But what happens when you have harmful modifications in your genome that you don't want to pass down? Baby plants have evolved a method to wipe the slate clean and reinstall only the modifications that they need to grow and develop. Cold Spring Harbor Laboratory (CSHL) Professor & HHMI Investigator Rob Martienssen and his collaborators, Jean-Sébastien Parent and Institut de Recherche pour le Développement Université de Montpellier scientist Daniel Grimanelli, discovered one of the genes responsible for reinstalling modifications in a baby plant's genome. A plant's genomic modifications--called epigenetic ...

Study finds gender pay gap in large government agency

2021-05-20
The study sought to describe and explain gender pay differences in the U.S. Department of Health and Human Services between 2010 and 2018. HHS comprises a quarter of the country's governmental public health workers, with over 80,000 employees. Understanding what may be driving wage gaps at HHS provides opportunities for employers and legislators to take action to support women in the health care field, said lead author Zhuo "Adam" Chen, an associate professor of health policy and management at UGA's College of Public Health. "A large percentage of the health care workforce are women," said Chen. "If you have underpaid women in the profession, I don't think it spells good things for the public health system." Chen ...
