Unhealthy behaviors were defined as current or recent smoking, nonmoderate alcohol consumption (abstinence or heavy drinking), fruit and vegetable consumption less than twice per day, and physical inactivity (&lt;1&nbsp;h\/wk of moderate and &lt;1&nbsp;h\/wk of vigorous physical activity). For each unhealthy behavior, a cumulative score was calculated as the number of times a person reported the behavior over the three assessments divided by 3. The score ranged between 0 (never) and 1 (all three times).<\/p>\n<p><strong>RESULTS:<\/strong><\/p>\n<p>In linear regression models adjusted for age, sex, education, marital status, and height, all unhealthy behaviors in 1991-93 were associated with slower walking speed in 2007-09, with differences ranging from 0.10 (nonmoderate alcohol consumption) to 0.25 (physical inactivity) of a standard deviation between participants with and without the unhealthy behavior (Pt-test &lt;.001). For walking speed, the accumulation-of-risk model provided the best fit for unhealthy diet (&beta; for a 1-point increment in the low fruit and vegetable consumption score&nbsp;=&nbsp;-0.29, 95% confidence interval (CI)&nbsp;=&nbsp;-0.36 to -0.22) and physical inactivity (&beta;&nbsp;=&nbsp;-0.37, 95% CI&nbsp;=&nbsp;-0.45 to -0.29). For smoking and nonmoderate alcohol consumption, a cumulative effect was also observed, but partial F-tests did not suggest that it provided a better fit than models with behaviors in 1991-93, 1997-99, or 2002-04. All behavioral scores except smoking were associated with grip strength, but F-tests supported the accumulation-of-risk hypothesis only for physical inactivity.<\/p>\n<p><strong>CONCLUSION:<\/strong><\/p>\n<p>These findings highlight the importance of duration of unhealthy behaviors, particularly for diet and physical activity, when examining associations with physical functioning.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-30763","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Department of Epidemiology and
