Australian researchers confirm the importance of regular physical activity for stroke prevention. Analyzing data collected in the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study involving 30,239 Americans, ages 45 years and over, with follow-up every 6 months for stroke events. Michelle N. McDonnell, from the University of South Australia (Australia), and colleagues found that 33% of the subjects reported a lack of physical activity, which associated with a hazard ratio of 1.2. While there was no significant association between physical activity frequency and risk of stroke by sex groups, there was a trend toward increased risk for men reporting physical activity of zero to 3-times a week, as compared with those who were active four or more-times a week. The study authors warn that: “Self-reported low [physical activity] frequency is associated with increased risk of incident stroke.”

Tip #192 - Stay Connected
Researchers from the University of Chicago (Illinois, USA) report that social isolation may be detrimental to both mental and physical health. The team analyzed data from the National Social Life, Health, and Aging Project, a nationwide US study involving 3,000 men and women, ages 57 to 85 years. They arrived at three key findings regarding the relationships between health and different types of isolation:
• The researchers found that the most socially connected older adults are three times as likely to report very good or excellent health compared to those who are least connected, regardless of whether they feel isolated.
• The team found that older adults who feel least isolated are five times as likely to report very good or excellent health as those who feel most isolated, regardless of their actual level of social connectedness.
• They determined that social disconnectedness is not related to mental health unless it brings feelings of loneliness and isolation.
Separately, Rush University Medical Center (Illinois, USA) researchers studied 906 older men and women, testing their motor functions (including grip, pinch strength, balance, and walking) and surveying their social activity, for a period of 5 years. Those study participants with less social activity were found to have a more rapid rate of motor function decline. Specifically, the team found that every one-point decrease in social activity corresponded to an increase in functional aging of 5 years, translating to a 40% higher risk of death and 65% higher risk of disability.
