OBJECTIVE: To examine the relationship between physical activity levels measured objectively by accelerometry and the use of mental health services (MHS) in a representative sample of males and females. METHOD: NHANES 2003-2004 is a cross-sectional study of the civilian, non-institutionalized US adult population. Participants reported whether or not they had seen a mental health professional during the past 12 months. Three measures of daily physical activity (light minutes, moderate-vigorous minutes, and total activity counts) and sedentary minutes were determined by accelerometry. The relationship between physical activity and use of MHS was modeled with and without adjustments for potential socioeconomic and health confounders. RESULTS: Of the 1846 males and 1963 females included in this analysis, 7 and 8% reported seeing mental health professionals during the past 12 months, respectively. Men who used MHS were significantly less active than men who did not use MHS (227,700 versus 276,900 total activity counts, respectively, p < 0.05). Men who did not use MHS engaged in 38 min (95% CI 16.3, 59.0) more of light or moderate-vigorous physical activity per day than men who used MHS. Physical activity levels of women, regardless of MHS use, were significantly lower than men who did not use MHS. Differences in total physical activity between women who did and did not use MHS were small (1.3, 95% CI - 14.0, 11.4). CONCLUSION: Men and women who used MHS were relatively sedentary. Additional research is warranted to determine if increasing physical activity levels results in improved mental health in individuals who use MHS.

    • "Whereas the LRC activity levels did not reflect PA measured by accelerometer, a moderate correlation was observed with Wmax and VO2peak. This finding is in line with the original validation study of the LRC which showed a significant association of the LRC activity levels with VO2peak but not with physical activity measured by accelerometry in a healthy adult population [8,29,30]. In contrast to the individual LRC activity levels, neither the physical activity derived from the 7D-PAR or from the HAES questionnaire correlated with measures of physical fitness. "

    ABSTRACT: The objective of this study was to validate physical activity questionnaires for cystic fibrosis (CF) against accelerometry and cycle ergometry. 41 patients with CF (12-42 years) completed the Habitual Activity Estimation Scale (HAES), the 7-Day Physical Activity Recall questionnaire (7D-PAR) and the Lipid Research Clinics questionnaire (LRC) and performed an incremental exercise test according to the Godfrey protocol up to volitional fatigue. Time spent in moderate and vigorous physical activity (MVPA) assessed objectively by accelerometry was related to the time spent in the respective activity categories by correlation analyses and calculating intraclass correlation coefficients (ICC). Furthermore, the results of the exercise test were correlated with the results of the questionnaires. Time spent in the categories 'hard','very hard' and 'hard & very hard' of the 7D-PAR (0.41 < r < 0.56) and 'active' (r = 0.33) of the HAES correlated significantly with MVPA. The activity levels of the LRC were not related to objectively determined physical activity. Significant ICCs were only observed between the 7D-PAR activitiy categories and MVPA (ICC = 0.40-0.44). Only the LRC showed moderate correlations with the exercise test (Wmax: r = 0.46, p = 0.002; VO2peak: r = 0.32, p = 0.041). In conclusion, the activity categories 'hard' and 'very hard' of the 7D-PAR best reflected objectively measured MVPA. Since the association was at most moderate, the 7D-PAR may be selected to describe physical activity within a population. None of the evaluated questionnaires was able to generate valid physical activity data exercise performance data at the individual level. Neither did any of the questionnaires provide a valid assessment of aerobic fitness on an invidual level.

    • "Using accelerometers first of all helps us to eliminate the concern for examining associations between two self-reported measures, and secondly permits an examination of different components of physical activity (i.e., sedentary, light, moderate and vigorous) in a way that self-reported measures struggle to do. The paper follows two previously published epidemiological studies in MENPA that have also involved objectively measured physical activity (Janney et al., 2008; Yoshiuchi et al., 2010). This work is in its infancy; while other research also seeks to explore how the volume of sedentary time is associated with and possibly impacts on physical health (e.g., Type II diabetes), the implications for mental health may be intuitively worth further investigation.

    ABSTRACT: Previously reported bus encoding approaches reduce crosstalk delay but they ignore the effects of inductive coupling between the bus lines, i.e. crosstalk noise. Aiming to solve this issue, this paper presents a modified bus-invert technique which minimizes crosstalk noise, as well as delay and power, at the expense of a small area overhead.
