A study that followed more than 12,000 older Australians for 11 years found that people who often read, stayed close to friends and family, and got out into their community became frail more slowly than people who did these things less often1. Frailty here means a broad loss of the body’s reserves across many systems, which leaves a person more vulnerable to falls, illness and other setbacks1. The study watched people over time rather than testing the activities, so it shows a link, not proof that the activities themselves slow frailty.
What happened
The researchers drew on the ASPREE Longitudinal Study of Older Persons, known as ALSOP, a large group of Australians aged 70 and older who were living in their own homes rather than in care1. All 12,862 people in the analysis filled in a questionnaire about their social life at the start, and their frailty was checked every year for 11 years. Just over half (54.4%) were women1.
The team asked about 19 everyday activities and used a statistical method that groups activities people tend to do together. That produced seven types1:
- Passive mental activities: reading, watching TV, listening to music
- Adult literacy: writing letters, using a computer
- External outings: getting out into the community
- Interpersonal networks: keeping close relationships
- Social activities: group and community involvement
- Creative or artistic activities: arts, crafts, music
- Active mental activities: puzzles and games
The researchers call this mix “lifestyle enrichment.” Exercise and diet usually get most of the attention in healthy-aging research, and this kind of social and mental engagement has been studied far less as a way to delay frailty1.
The evidence so far
Frailty was scored two ways: a 67-item frailty index, which adds up health problems across many areas, and the modified Fried phenotype, a checklist of physical signs1. For most of the seven activity types, doing them often went along with slower frailty and a lower chance of becoming frail, and the pattern held on both measures1.
How fast frailty grew
On the yearly rise in frailty, the reported differences were1:
- Passive mental activities and adult literacy: a 0.04-unit slower yearly increase, the largest of any group
- External outings: 0.03 units slower each year
- Close relationships and social activities: 0.02 units slower each year
- Creative and artistic activities: 0.01 units slower each year
- Puzzles and games: no clear difference
The coverage available to Biohack does not explain what one unit means on the frailty scale, so these numbers are hard to translate into everyday terms.
Who became frail
Over a typical follow-up of about 7.4 years, 3,630 people became frail1. Reading and other passive activities, close relationships, social activities, outings, letter writing and computer use, and puzzles and games were each tied to a 2% to 5% lower risk of becoming frail1. Two results pointed in different directions. Creative and artistic activities were tied to a slower rise in frailty but not to a lower chance of becoming frail. Puzzles and games showed the reverse: no slower rise, but a lower chance of becoming frail1.
What it does not show yet
This is an observational study. Nobody was asked to start reading or join a club; the researchers recorded what people already did and followed their health. That design cannot rule out other explanations. For example, people who were already healthier, wealthier or more mobile may have found it easier to go out and socialize, and their better health could explain part of the link.
The study itself points to one such pattern. The links were stronger in women and in people with middle-to-high socioeconomic status, meaning income, education and social standing1. The researchers suggest this likely reflects differences in access to community resources, free time and local infrastructure, not that the activities matter less for men or for people with lower incomes1. That explanation is their interpretation; the data reported do not test it directly.
Activities were measured once, at the start, through a questionnaire1. If people changed their habits over the following decade, the study as described would not capture that. The effects tied to each activity type were also small, a few percent lower risk at most1.
The possible reasons behind the link are not established. The authors suggest that social and mental engagement may help through social support, lower stress and keeping the brain adaptable, and note that social and creative pursuits have been tied to better mental health and independence1. These are proposed pathways, not findings of this study.
Who is behind it
The data come from ALSOP, a long-running study of Australians aged 70 and older1. The coverage Biohack read does not name the journal, the authors or the funders, so we cannot report on funding or possible conflicts of interest. Biohack’s account rests on a summary from mindbodygreen, a wellness site whose article page also carries advertising for its own supplement products1. We will update this thread if the full paper becomes available to us.
How it fits the field
Most long-term frailty research has focused on the body. A 2022 study in the journal BMC Geriatrics followed 5,131 people in Taiwan aged 60 and over for 20 years and tracked how their physical activity changed2. People whose activity rose over time had the lowest frailty scores by 2015, and people whose activity fell had the highest2. That study also found older age, being male, poor oral health, diabetes, chronic kidney disease and depressive symptoms were tied to frailty2. It, too, was observational.
The Australian study adds social and mental activities to that picture. Groups that run programs for older people already promote social activity as good for health. The All Seniors Foundation, a US nonprofit, says on its website that social involvement is linked to better physical health and less loneliness3. Those are general claims from an advocacy group, not new data. The new study gives some long-term numbers on the question, while still stopping short of showing cause and effect.
Biohack has also covered trials that do test interventions in frail older adults, including virtual reality training for people with early memory problems and exercise for older women living with HIV. Trials like these, where people are assigned an activity, are the kind of test that could show whether a habit changes frailty.
What to watch next
- The full paper: its journal, authors, funding and exactly how the frailty scores were scaled.
- Adjustment for health at the start: how much of the link remains once the starting health, income and mobility of participants are fully accounted for.
- Testing the idea: whether anyone runs a trial that assigns older adults to reading groups, outings or social programs and measures frailty.
- Access: whether the stronger links in women and better-off people hold up, and whether easier access to community spaces narrows the gap.
