Task: Fact Verification
Input (English): Paragraph: Cost wasn’t mentioned, but given that this is light activity, we’ll rate this N//A. Still, the story could have explicitly said that the activities that are highlighted in this study probably have no cost associated with them. The story notes that engaging in light activity for 30 minutes per day reduced relative risk of mortality during the study period by 12 percent. It also noted that engaging in moderate activity for 30 minutes per day reduced that risk by 39 percent. But what about the absolute risk reduction? As the NIH has noted, the benefits of physical activity far outweigh the risks. For that reason, we won’t ding this story for not going into details regarding the risks associated with light physical activity. Nonetheless, it would have been nice to see the story mention that older adults may want to consult with a health professional to determine what types of activity they should (or should not) engage in. The story does briefly point out that this type of study can’t prove cause and effect, though it quickly pivoted to a “however…” to weaken that point. A limitation that should have made it into the news story is that individuals weren’t assigned a level of activity–rather they presumably went about their usual activities for a week (just a week) and the device captured it. The authors then categorized individuals into three categories of increasing level of activity. The challenge is that people who are less active, may be that way for a reason. Maybe they are sick, or have other issues that make them less active. And that might have been a temporary problem. This helps readers understand why the study can’t prove cause and effect. There’s really no disease mongering here, though there is one note we’d like to make that falls under this heading as well as anywhere. The story tells readers that increased physical activity is “linked to a lower risk of death.” Reader, we have bad news…death is inevitable. It would be more accurate to note that physical activity reduced the relative risk of dying during a given timeframe (in this case, the three-year period of observation). No outside sources are cited in the story, nor does the story make clear who funded the research (addressing potential conflicts of interest). The study compared different levels of physical activity. As such, it was comparative. However, there are other important lifestyle habits that affect mortality (cigarette smoking or drinking alcohol, for instance), and it would be interesting to know how helpful light activity is compared to these other lifestyle modifications. The story does a good job of defining what light activity means, which is important for understanding how accessible it is. Bike riding is a moderate activity, for example, whereas “strolling around the neighborhood” is a light activity. The story refers to national guidelines and some (nonspecific) “recent analyses,” noting that the “new study refutes that research.” But is this the first study to show benefits like these from engaging in low-intensity daily activities? No. For example, this 2014 study published in Preventive Medicine examined “examine[d] the association between household physical activity and all-cause mortality in a cohort of older adults from Spain.” The study relied on self-reporting from study participants, but found that — among other things — “Household physical activity may have benefits for longer survival in older women.” It would have been interesting to see the article look at how the new study compared to the 2014 study. Do the findings support each other? How do they differ? This sort of context would be valuable for readers. What does appear novel is the use of a device to assess activity–versus recording what people report as their activity levels. This is borderline. The story maps very closely to the news release. However, the story appears to incorporate quotes from study author Andrea LaCroix that are not found in the news release. Claim: Want to Live Longer? Every Movement Counts, Even Cleaning the House
