Exploring actograms, actigraphs, and how preschoolers' sleep affect executive function 🧠
Ever done research with preschoolers? It’s part science, part chaos, and 100% unpredictable! 🤪

So women get less productive sleep when sleeping with their partner while men benefit more.
NBC NEWS WATCH HEALTH NEWS Men sleep better beside mate; women worse Women sleep less soundly when they share a bed with a romantic partner, while men actually sleep better when they sleep next to their women, says a study published this month in Sleep and Biological Rhythms. Taylor's trouble getting a good night's rest next to her husband isn't unusual. Women sleep less soundly when they share a bed with a romantic partner, a study published this month in Sleep and Biological Rhythms found. Surprisingly, men actually sleep better when they sleep next to a woman. There are a lot more couples sleeping separately than you might guess, says Mark Mahowald, director of the Minnesota Regional Sleep Disorders Center in Minneapolis and a professor of neurology at the University of Minnesota Medical School. An estimated 23 percent of American couples sleep apart, according to a survey by the National Sleep Foundation. A Canadian study reported that 34 percent of couples hit the sack separately. Women may have a tougher time sharing a bed because men are much more likely to be snorers, says Mahowald. And often, it's the woman who has to move to a different bed - or room, in some cases - when the decibel level of her husband's snoring crescendos to an intolerable le The actigraph's measurements would most likely have been even more distinct if the couples in the study had been older, says sleep expert Michael Perlis. That's because snoring becomes more of an issue as men age, explains Perlis, director of the Sleep Research Lab and an associate professor in the department of psychiatry at the University of Rochester in Rochester, N.Y. Psychologist Wendy Troxel isn't surprised to see that men do better when sleeping in a shared bed. Studies have shown that men are very dependent on close relationships - contrary to popular stereotypes, says Troxel, a researcher at the University of Pittsburgh who has studied how the quality of a relationship affects overall health and sleep in men and women. actigraphs showed that the women's sleep was more fragmented on nights when they shared a bed, than when they slept alone. The differences weren't huge, but they were significant. The researchers speculated that women's fretful sleep might be caused by brain wiring differences between men and women. Women tend to be lighter sleepers because they historically have been the ones caring for infants, the researchers suggested. In general, men show much clearer benefits from committed relationships, Troxel says. "My research shows that married men are much happier and healthier than unmarried men," she adds. "The findings are much less consistent with women."

Amortized Bayesian inference for actigraph time sheet data from mobile devices
By Zhou, Banerjee
Mobile data technologies use ``actigraphs'' to furnish information on health variables as a function of a subject's movement. The advent of wearable devices and related technologies has propelled the creation of health databases consisting of human movement data to conduct research on mobility patterns and health outcomes. Statistical methods for analyzing high-resolution actigraph data depend on the specific inferential context, but the advent of Artificial Intelligence (AI) frameworks require that the methods be congruent to transfer learning and amortization. This article devises amortized Bayesian inference for actigraph time sheets. We pursue a Bayesian approach to ensure full propagation of uncertainty and its quantification using a hierarchical dynamic linear model. We build our analysis around actigraph data from the Physical Activity through Sustainable Transport Approaches in Los Angeles (PASTA-LA) study conducted by the Fielding School of Public Health in the University of California, Los Angeles. Apart from achieving probabilistic imputation of actigraph time sheets, we are also able to statistically learn about the time-varying impact of explanatory variables on the magnitude of acceleration (MAG) for a cohort of subjects.

#sleepSky I want to get researcher grade actigraphs (something a little more robust than FitBit). Right now I'm considering Activinsights &Axivity. Would appreciate any input!
Want to have these last so I can get the most out of my startup. @tfblanken.bsky.social @jparentphd.bsky.social

Alzheimer's: Daily activity pattern changes could predict disease
Researchers used wrist-worn devices called 'actigraphs' to track participants' daily activity patterns. They found that changes in those activity patterns correlate with signs of cognitive decline.
