Moderate to vigorous physical activity (MVPA) is a modifiable health behavior that protects against many chronic diseases, including heart disease and cancer. 1 Adolescence is a critical window during which MVPA declines. 2 This decline occurs earlier among girls than among boys, 2 and nonwhite

Moderate-to-vigorous physical activity (MVPA) is well known to have multiple implications for the health of children and adolescents ( Galan et al., 2013 ). The World Health Organization ( 2010 ) recommends that children and adolescents should accumulate at least 60 min of MVPA daily to gain the

Background:
A study deriving a threshold for moderate- to vigorous-intensity physical activity (MVPA) in terms of accelerometer counts in 12-year-old children was repeated with a subset of the same children at 16 years.
Methods:
Fifteen girls and thirty boys took part in 6 activities (lying, sitting, slow walking, walking, hopscotch and jogging) while wearing an Actigraph 7164 accelerometer and a Cosmed K4b2 portable metabolic unit. Random intercepts modeling was used to estimate cut points for MVPA (defined as 4 METs).
Results:
Using a single model, the sex-specific thresholds derived for MVPA at 16 years were some way below the 3600 counts/minute used for both sexes at age 12, particularly for girls. However graphical examination suggested that a single model might be inadequate to describe both higher- and lower-intensity activities. Models using only lower-intensity activities close to the 4 METs threshold supported retention of the 3600 counts/minute cut point for both sexes.
Conclusions:
When restricting to lower-intensity activities only, these data do not provide sufficient evidence to change the previously established cut point of 3600 counts/minute to represent MVPA. However, further data and more sophisticated modeling techniques are required to confirm this decision.

Background:
Disruptive sleeping patterns have been linked to serious medical conditions. Regular physical activity (PA) has a positive impact on health; however, few research have investigated the relationships between PA, body mass index (BMI), sedentary behaviors (SB), and sleep disorders (SD).
Methods:
Data from the 2005–2006 NHANES were analyzed for this study. Participants (N = 2989; mean age = 50.44 years) were grouped based upon responses to SD questions. Accelerometers were used to measure the average time spent in moderate or vigorous physical activity (MVPA) and SB. Multinomial logistic regression analyses were used to examine the associations between PA, SB, and SD after controlling for covariates and to explore potential moderation effects among common risk factors and the main study variables.
Results:
Among middle-aged adults, PA was significantly associated with SD [Wald χ2 (8) = 22.21; P < .001]. Furthermore, among adults in the highest tertile of SB, PA was significantly associated with SD [Wald χ2 (8) = 32.29; P < .001].
Conclusions:
These results indicate that middle-aged adults who are less active may have increased likelihoods of SD. It is important for health care professionals to continue developing methods for increasing PA to decrease the risk of SD.
