Current status and influencing factors of digital health literacy and health self-management ability of older adults with chronic diseases in China: a cross-sectional study
This cross-sectional study of 286 older Chinese adults with chronic diseases reveals that digital health literacy and health self-management abilities are at moderate levels and are significantly influenced by sociodemographic and internet usage factors, while also showing that subjective health ratings often fail to reflect actual disease prevalence.

Imagine your health as a massive, complex video game. In this game, Chronic Non-Communicable Diseases (like high blood pressure, diabetes, or fatty liver) are the persistent, annoying glitches that keep popping up. To beat the game, you need a character skill called Digital Health Literacy (DHL). Think of DHL as your "player manual" for the digital world: it's your ability to search for health info, understand if a website is telling the truth, and use apps to manage your diet or meds. Then, there's Health Self-Management Ability (HSMA), which is your actual "in-game performance"—how well you're actually eating, exercising, and taking your pills based on that manual.
A team of researchers from the First Affiliated Hospital of the Army Medical University in China decided to check the stats of 286 players (older adults, aged 60 and up) who visited a hospital for a physical check-up in April 2024. They wanted to see how good these players were at reading the manual (DHL), how well they were playing the game (HSMA), and how they felt about their own character status (Self-Evaluation of Health Status, or SEHS).
The Scoreboard: Moderate Skills, Big Gaps
The results showed that the average player's "Digital Health Literacy" score was 43.77 (out of a possible 75). That's a "moderate" level—like a player who knows how to move their character but hasn't mastered the advanced combos yet.
Here's the twist the paper explicitly rules out: Feeling good doesn't mean you are glitch-free.
The researchers found that a player's subjective feeling of their health (SEHS) did not effectively reflect their actual number of chronic diseases. You could feel like a superhero, but your blood tests might show you have diabetes or high creatinine. The paper argues that relying on how you feel is like judging your video game score by how happy you are while playing, rather than checking the actual points on the screen. The only time feelings matched the data was for players with diabetes; for everyone else, the "feeling" score and the "actual disease" score were disconnected.
The Cheat Codes: What Actually Helps?
The study suggests that certain "cheat codes" (factors) significantly boost your ability to read the manual and play the game:
- The "Urban vs. Rural" Map: Players living in cities had higher scores than those in towns or rural areas.
- The "Education" Power-up: Higher education levels (like a bachelor's degree or above) were linked to much better digital skills.
- The "Money" Inventory: Players with higher monthly incomes (over 5,000 yuan) and those with medical insurance had better scores. If you have no insurance, your scores drop significantly.
- The "Family" Co-op Mode: This is a big one. The paper suggests that having family members help you navigate the internet is crucial. Players who actively asked for help or passively received guidance from family did better. In China, where 91.6% of older adults live with relatives, this "co-op mode" is a massive advantage.
- The "Trust" Meter: If a player thinks online health info is useful, easy to use, and reliable, their skills go up. If they think it's risky or hard to use, their skills go down.
The "Glitch" of Internet Habits
Here is a weird finding that the paper highlights: Players who had a habit of surfing the internet actually had lower self-rated health scores than those who didn't. The authors suggest this might be because when you search for your symptoms online, you might start thinking, "Oh no, this looks like a serious disease!" which makes you feel worse, even if you aren't actually sicker.
The Numbers Don't Lie
The paper measured these things using specific tools:
- Digital Health Literacy (DHL): Average score 43.77 (SD 14.33).
- Health Self-Management (HSMA): Average score 160.11 (SD 19.62).
- Self-Evaluation of Health (SEHS): Average score 98.55 (SD 12.59).
There was a strong link between reading the manual (DHL) and playing the game well (HSMA), with a correlation coefficient of 0.559. This suggests that if you get better at finding and understanding digital health info, you are likely to get better at managing your actual health.
What the Paper Does NOT Say
The paper is careful not to say that digital skills caused the diseases or that they are the only thing that matters. It explicitly states that this is a "cross-sectional study," meaning it's a snapshot in time. It suggests relationships but doesn't prove cause-and-effect like a long-term experiment would. It also notes that because they only looked at patients in Chongqing, the results might not represent every older adult in China.
The Final Boss Strategy
The researchers conclude that while digital health tools are powerful, they aren't magic. To help older adults beat the chronic disease glitches, we need to:
- Bridge the Digital Divide: Make sure people with lower incomes, less education, or those living in rural areas get the help they need.
- Use the Family Co-op: Encourage younger family members to teach older relatives how to use health apps safely.
- Design Better Interfaces: Make health websites easier to use (bigger fonts, simpler steps) so they don't feel "risky" or "hard."
- Check the Real Stats: Don't just ask, "How do you feel?" Check the actual blood work and clinical data, because feelings can be misleading.
In short, the paper suggests that if we want older adults to manage their health better in the digital age, we need to give them better manuals, a supportive co-op team, and a user-friendly interface, while remembering that how they feel isn't always a reliable map of their actual health status.
