International Surveillance Study of Movement Behaviours in the Early Years
The International Surveillance Study of Movement Behaviours in the Early Years (SUNRISE) represents a critical global initiative designed to address the urgent need for standardized data on physical activity, sedentary behavior, and sleep among children under the age of five. As the early years are a foundational period for health and development, understanding how children moveor remain sedentaryis essential for shaping public health policies and interventions.
The Importance of Early Childhood
The first five years of life are characterized by rapid physiological, cognitive, and social development. During this time, the habits established within a childs routine often set the trajectory for their future health. The SUNRISE study recognizes that movement behaviors, which include physical activity, sedentary time (such as screen use), and sleep duration, are interlinked and critical to preventing non-communicable diseases later in life, including obesity and metabolic disorders.
Objectives of the SUNRISE Study
The primary objective of the SUNRISE study is to generate robust, comparative data across diverse countries and socioeconomic backgrounds. While many studies have focused on adolescents and adults, high-quality, standardized research in the early years has historically been sparse, particularly in low- and middle-income countries. By creating a global surveillance system, the study aims to:
- Determine the proportion of children meeting the World Health Organization (WHO) guidelines for physical activity, sedentary behavior, and sleep.
- Identify socioeconomic and environmental factors that influence these behaviors globally.
- Provide a baseline that allows countries to track changes over time and evaluate the effectiveness of national health policies.
Defining Movement Behaviours
The study views movement behavior as a holistic "24-hour" experience. It is not enough to look at physical activity in isolation. Instead, the study examines:
- Physical Activity: Ranging from structured play to active transport and movement within the home environment.
- Sedentary Behavior: Specifically focusing on screen time and prolonged periods of inactivity, which have become increasingly prevalent in modern childhood.
- Sleep: Examining the duration and quality of nighttime sleep and daytime naps, which are crucial for physical growth and neurological health.
Challenges and Methodology
Conducting research with toddlers and preschoolers presents unique challenges. Unlike older children who can self-report, researchers must rely on parental reports and objective measures like wearable devices (accelerometers) that can capture movement data without requiring the child to understand the research protocol. The SUNRISE methodology is designed to be culturally sensitive, acknowledging that "active play" may look very different in a rural village than in a high-density urban environment.
Impact and Future Directions
The findings from the SUNRISE study are instrumental in informing evidence-based guidelines. When governments understand the barriers to physical activity in their specific regionswhether due to lack of safe outdoor spaces, cultural norms, or screen exposurethey can better allocate resources to support family health.
As the study continues to collect data across the globe, it serves as a powerful advocacy tool. It highlights the global challenge of sedentary behavior and underscores the need for environments that facilitate movement. Ultimately, the work of the SUNRISE study is about ensuring that every child, regardless of geography, has the best possible start to a healthy, active life.
