You are an expert at identifying data availability statements in scientific text. A data availability statement describes where research data can be found or how it can be accessed.<|eot_id|><|start_header_id|>user<|end_header_id|>

Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: To the best of our knowledge , this is the first study to test the mediation hypotheses of the recently proposed conceptual models of parenting influences on children 's physical activity ( Patrick et al . , 2013;Sleddens et al . , 2011 ) . Other strengths of this study are its conceptual foundations , the large sample and the objective measurement of children 's physical activity using accelerometers . Despite the strength of our objective measure of physical activity , the lack of consensus regarding which cut - points are most accurate for classifying MVPA among children and youth is a limitation of the literature , and inherently our study ( Freedson et al . , 2005;Kim et al . , 2012 ) . However , in following the current recommendations for researchers ( Freedson et al . , 2005;Kim et al . , 2012 ) , we chose the most appropriate MVPA cut - points based on our sample 's age , and the methodology used in the original calibration study ( Evenson et al . , 2008 ) . Some additional limitations should be noted . Firstly , on average , the children in our study met the UK physical activity guidelines and on average , parents reported that they provided positive support for their children 's physical activity . As such , our findings are reflective of families that are supportive of activity and have children who are relatively more active . Parents included in the analysis were less deprived , and provided greater nurturing and logistic support than excluded parents . Further work is needed to develop strategies to ensure satisfactory adherence to data collection protocols , in particular accelerometer measures amongst children from families across the socioeconomic spectrum .<|eot_id|><|start_header_id|>assistant<|end_header_id|>
