Moderate to vigorous physical activity (MVPA) benefits a child’s health. 1 Accelerometers are commonly used to objectively measure how much MVPA children accumulate. Issues inherent to accelerometers may lead to biased MVPA estimates. 2 , 3 One of these issues is nonwear time. Nonwear time occurs

physical activity (PA) recommendations for adults – this is typically a minimum of 150 minutes of moderate-to-vigorous physical activity (MVPA) per week ( World Health Organisation, 2009 ). Meeting PA recommendations is known to be associated with a reduction in a number of health outcomes, such as

Nonetheless, some uncertainty remains

Literature Review The health benefits of regular physical activity (PA) are well known ( U.S. Department of Health & Human Services, 2008 ). Despite this knowledge, data show that only 25% of elementary school children in Qatar accumulate the recommended 60 min of moderate to vigorous physical

When the same set of data is

Background:

Few studies have used ecological models to study multiple levels of association with objectively measured moderate-to-vigorous physical activity (MVPA) in young children from middle-income countries. The purpose of this study was to examine potential correlates of objectively measured MVPA in Brazilian children.

Methods:

The sample consisted of 328 children. An Actigraph GT3X+ accelerometer was used to monitor MVPA over 7 days. Body mass index and body fat percentage were measured using a bioelectrical impedance scale. Questionnaires completed by the children, their parents, and school personnel queried individual, family and home, and school-level environmental correlates.

Results:

Children averaged 59.3 min/d in MVPA (44.5% met MVPA guidelines), and 51.8% were overweight/obese. For boys and girls combined, significant correlates (P < .05) of MVPA were waist circumference (β = –.007), travel mode to school (β = .140), maternal employment status (β = –.119) and TV in bedroom (β –.107). In boys, significant correlates of MVPA were waist circumference (β = –.011), travel mode to school (β = .133), and maternal employment status (β = –.195). In girls, the only significant correlate of MVPA was travel mode to school (β = .143).

Conclusions:

Several factors were identified as correlates of MVPA in Brazilian children; however, only travel mode to school was common for both boys and girls.

In contrast, increasing the levels of physical activity, especially moderate-to-vigorous physical activity (MVPA) has a beneficial effect on elevated cardiometabolic risk factors. 6 , 7 To date, few studies have investigated how different

The UK Government advises that children and young people aged 5–18 years should participate in structured and unstructured activities throughout the day to achieve the recommended 60 daily minutes of moderate to vigorous physical activity (MVPA). Physical activity of this intensity stimulates the
