Sleep, Diet, and Environment: A Nomogram for Early Anxiety Detection in 11,654 Health Examination Adults
This study developed and validated a nomogram integrating demographic, behavioral, dietary, environmental, and clinical factors to effectively screen for anxiety symptoms in a large cohort of adults undergoing routine health examinations.

Imagine your mind is like a high-tech security system for your body. Just as a house alarm might go off because of a broken window, a loose door, or a sudden noise, your brain's "anxiety alarm" can be triggered by a mix of things happening inside and outside your life. Scientists have long known that anxiety is a common feeling that can make your heart race, your stomach churn, and your sleep vanish. But usually, we only check this alarm when someone is already screaming for help or visiting a specialist. This paper asks a different question: What if we could spot the alarm before it starts blaring, right when people are just walking in for a routine check-up? The researchers wanted to see if simple, everyday habits—like how you sleep, what you eat, and even the air you breathe—could act as early warning lights, helping us catch anxiety symptoms before they become a full-blown crisis.
The team behind this study, led by researchers from Central South University in China, decided to build a special "anxiety detector" for the 11,654 adults who visited their hospital for routine health exams between 2015 and 2025. Think of this detector as a digital recipe or a "scorecard" called a nomogram. Instead of needing a psychiatrist to interview you for an hour, this tool uses a list of 14 simple questions and facts to calculate your risk. The researchers gathered data on everything from your education level and medical history to whether you eat spicy food, binge eat, or live near noisy traffic. They then used a smart computer method (called LASSO regression) to sift through all this information and find the specific ingredients that actually matter most for predicting anxiety.
Here is what their "recipe" revealed. The two biggest ingredients that light up the anxiety alarm are poor sleep quality and binge eating. If you are sleeping badly, your risk score jumps up dramatically—so much so that it was the strongest predictor in their model. Binge eating was the second most powerful signal. The study also found that other factors play a role: having a history of allergies, taking long-term medication, or having had surgery in the past can increase your risk. On the flip side, some things act like "shield" ingredients. Having a higher level of education and eating soybean products every day were linked to a lower risk of anxiety. Surprisingly, even environmental factors like breathing in air pollution, being exposed to cooking oil fumes, or living in a noisy area were part of the mix.
The researchers tested their new "anxiety detector" on a huge group of people, splitting them into a training group and a testing group to make sure it wasn't just guessing. The tool worked well, correctly identifying anxiety risk about 73% to 75% of the time in their tests. This isn't a perfect crystal ball, but it's a solid tool that suggests we can spot anxiety risks just by looking at a person's lifestyle and health habits. The study explicitly argues against the idea that we need to wait for someone to show severe psychiatric symptoms or that we only need to look at mental health history. Instead, it suggests that physical health checks are the perfect place to catch these early signs.
However, the authors are careful to note that this study is like taking a snapshot of a moment in time; it shows connections but doesn't prove that bad sleep causes anxiety or that eating soy prevents it. They also admit that because everyone in the study came from one hospital, the tool might need to be tested in other places to see if it works everywhere. Still, the findings offer a playful yet serious new way to look at mental health: by paying attention to the small, everyday details of our lives, we might be able to tune our internal security systems before the alarm ever goes off.
