Sickle cell disease (SCD) significantly affects physical functioning. We examined physical activity (PA) patterns in children with SCD versus a national sample and factors associated with PA and participation in physical education and organized sports.
One hundred children with SCD completed a 58-item survey with questions from the 2009–2010 National Health and Nutrition Examination Survey (NHANES) Physical Activity Questionnaire and others on physical education and sports, disease impact, and physical functioning.
Compared with NHANES participants, more children with SCD (67 vs 42%, p < .01) reported doing at least 10 min of moderate-to-vigorous intensity PA (MVPA)/week. Children with SCD also reported spending more days in MVPA (2.3 vs. 1.4 days/week, p < .01). However, fewer reported spending ³ 60 min/day in either vigorous PA (VPA) (24 vs. 43%, p = .01) or MVPA (17 vs 23%, p < .01). In addition, 90% and 48% of children with SCD participated in physical education and sports, respectively. Greater disease impact on PA and physical functioning were associated with lower participation.
Children with SCD are active at moderate to vigorous intensity for shorter durations. Negative personal beliefs about disease impact and poor physical functioning represent barriers to PA in SCD.

Few studies have examined the gender differences between C-reactive protein (CRP) and muscle strengthening activity (MSA).
The sample (n = 7533) included U.S. adult (≥20 years of age).participants in the 1999–2004 National Health and Nutrition Examination Survey (NHANES). Created categories of MSA participation included no MSA (referent group), some MSA (≥1 to <2 days/week), and meeting the 2008 Department of Health and Human Services (DHHS) recommendation (≥2 days/week). The dependent variable was elevated CRP (>3 to 10 mg/L).
Analysis revealed significantly lower odds of having elevated CRP for women reporting some MSA (OR 0.64; 95% CI 0.44–0.93, P = .0191). Significantly lower odds of men having elevated CRP was observed in those reporting MSA volumes meeting the DHHS recommendation (OR 0.72; 95% CI 0.59–0.88, P = .0019). Following adjustment for waist circumference (WC) these odds remained significant in men but not women.
These results suggest that WC may mediate the associations between MSA and CRP and this relationship may be stronger in women.

The interrelations between various physical activity domains have received little empirical attention in the United States. Of particular interest, given the potential applicability to traditionally underserved communities, is the nature of the association between occupational physical activity (OPA) and leisure-time physical activity (LTPA).
5448 adult men and women who participated in NHANES 1999–2000 were included in analyses. Linear regression was used to examine the bivariate and multivariable associations of OPA and education with LTPA. Generalized logit models were used to examine the association of education with OPA.
We found no association between education and LTPA. OPA was significantly positively associated with LTPA (P < .001). The association between OPA and LTPA was not strongest among those with low education and held only for men in gender-stratified analysis. Education was inversely associated with OPA (P < .001) in multivariable analysis.
Our findings lend preliminary support to the hypothesis that OPA is an important determinant of LTPA, particularly in men. This provides additional support to calls for assessment of OPA, particularly among individuals of low social class.

Analysis of the 2005–2006 National Health and Nutrition Examination Survey (NHANES) accelerometer data provides the descriptive epidemiology of peak 30-minute cadence (defined as the average steps/min recorded for the 30 highest, but not necessarily consecutive, minutes in a day) and peak 1-minute cadence (defined as the steps/min recorded for the highest single minute in a day) by sex, age, and body mass index (BMI).
Minute-by-minute step data were rank ordered each day to identify the peak 30-minute and 1-minute cadences for 3522 adults (20+ years of age) with complete sex, age, and BMI data and at least 1 valid day (ie, 10/24 hours of accelerometer wear) of accelerometer data. Peak values were averaged across days within participants by sex, age, and BMI-defined categories.
U.S. adults average a peak 30-minute cadence of 71.1 (men: 73.7, women: 69.6, P < .0001) steps/min and a peak 1-minute cadence of 100.7 (men: 100.9, women: 100.5, P = .54) steps/min. Both peak cadence indicators displayed significant and consistent declines with age and increasing levels of obesity.
Peak cadence indicators capture the highest intensity execution of naturally occurring ambulatory activity. Future examination of their relationship with health parameters using cross-sectional, longitudinal, and intervention designs is warranted.
