Accelerometer-Based Assessment of Physical Activity in Asian Children: Challenges, Trends, and Future Directions

Accelerometer-Based Assessment of Physical Activity in Asian Children: Challenges, Trends, and Future Directions

Introduction: The rise of sedentary lifestyles and increasing rates of obesity among Asian children have raised concerns regarding public health. Accelerometer-based physical activity (PA) evaluation provides an objective, quantitative method with acceptable validity and reliability to quantify PA in the child, and currently, there is increasing popularity in the use of accelerometers in PA studies in Asia. Objective: This review aims to examine the factors that need to be considered before conducting accelerometer-derived studies in Asian children while exploring the utility of accelerometers in assessing PA and sedentary behaviours. Method: This narrative review was undertaken using publications retrieved from PubMed, Google Scholar, Sci-Hub, and MEDLINE databases. The publications contained a combination of words related to accelerometry-based assessment of PA, sedentary behaviour, and PA in Asian children. Result: Despite the recognised benefits of PA, accurate measurement remains challenging. Accelerometer-based devices offer objective and quantitative data, yet their use in Asian countries is underexplored compared to Western nations because of wearing reluctance, fear of damage, stigma, and overemphasis on academic achievement. Challenges such as cultural preferences, socioeconomic factors, and technical limitations hinder the widespread adoption of accelerometers in PA research. Moreover, existing cut-points for defining PA levels are primarily based on Western populations, raising questions about their applicability to Asian children. This review highlights the need for culturally specific and age-appropriate PA guidelines and emphasises the importance of validating accelerometer-based measurements for accurate PA assessment in Asian children. Conclusion: When assessing PA, consideration needs to be given to specific challenges within the Asian context, including ethnicity, body composition, diet, and seasonal variation. Future research should focus on assessing the validity and reliability of accelerometerderived cut-points tailored to the Asian population to advance our understanding of PA behaviours and inform targeted interventions to promote active lifestyles in this demographic.
