Abstract: Background: Studies provide conflicting evidence for the protective effects of moderate-to-vigorous-intensity physical activity on depression. Recent evidence suggests that sedentary behaviors may also be associated with depression. Purpose: To examine the associations of accelerometer-derived moderate-to-vigorous-intensity physical activity and sedentary time with depression among a population-based sample. Methods: Cross-sectional study using 2,862 adults from the 2005–2006 US National Health and Nutrition Examination Survey. ActiGraph accelerometers were used to derive both moderate-to-vigorous-intensity physical activity and sedentary time. Results: Depression occurred in 6.8% of the sample. For moderate-to-vigorous-intensity physical activity, compared with those in quartile 1 (least active), significantly lower odds of depression were observed for those participants in quartiles 2 (OR=0.55, 95% CI, 0.34 to 0.89), 3 (OR=0.49, 95% CI, 0.26 to 0.93), and 4 (most active) (OR=0.37, 95% CI, 0.20 to 0.70) (p for trend p <0.01). In overweight/obese participants only, those in quartile 4 (most sedentary) had significantly higher odds for depression than those in quartile 1 (least sedentary) [quartile 3 vs 1 (OR=1.94, 95% CI, 1.01 to 3.68) and 4 vs 1 (OR=3.09, 95% CI, 1.25 to 7.68)]. Conclusion: The current study identified lower odds of depression were associated with increasing moderate-to-vigorous-intensity physical activity and decreasing sedentary time, at least within overweight/obese adults.

Objective: The primary objective of this study was to assess the suitability and readability level of publicly available educational print resources related to physical activity (PA)., Methods: Educational print resources related to PA (n=66) were requested from organizations (e.g., professional, commercial, government, and educational). The suitability assessment of materials (SAM) and the simple measure of gobbledygook (SMOG) readability measure were used to evaluate the suitability and readability of the PA resources., Results: Of the 66 PA resources, suitability scores were superior in only 10 resources (15%), adequate in 36 resources (55%), and inadequate/not suitable in 20 resources (30%). The average reading grade level for the PA resources was a 10th grade level (S.D.=1.82; Rg=5th grade to 15th grade). Only 56.5% (n=35) of PA resources depicted a primary PA recommendation that was consistent with the public health recommendation for PA., Conclusion: Results indicate that the majority of educational print resources related to PA have poor readability indices and inadequate to adequate suitability., Practice Implications: Health educators developing educational print resources related to PA must ensure these resources conform to the highest suitability standards. This includes developing resources that a) contain information consistent with current public health recommendations, and b) can be utilized by all individuals regardless of health literacy status.
