Levels and Patterns of Objectively Measured Physical Activity and Sedentary Time in 4-Year-Old Swedish Children
Insights
Physical activity (PA) in 4-year-olds is crucial for health. Alarmingly, most children are sedentary, and only one-third meet daily moderate-to-vigorous PA guidelines, missing key health benefits.
Area of Science:
- Pediatric Health
- Public Health
- Child Development
Background:
- Physical activity (PA) levels significantly impact health outcomes in early childhood, starting at 4 years of age.
- Sedentary time (ST) is a growing concern in pediatric populations.
- Establishing healthy PA patterns in early life is vital for long-term well-being.
Purpose of the Study:
- To characterize PA levels and patterns in a cohort of 4-year-old Swedish children.
- To quantify sedentary time (ST) among these young children.
- To determine the proportion of children adhering to recommended daily PA guidelines.
Main Methods:
- Utilized accelerometer data (Actigraph GT3X+) from 540 children in the PRIMROSE trial.
- Measured PA and ST over a one-week period in 4-year-old participants.
- Assessed average PA, light PA, moderate-to-vigorous PA (MVPA), and ST.
Main Results:
- Children averaged 6.7% of their day in MVPA and spent 45% sedentary.
- Only 33% of children met the guideline of 60 minutes of MVPA daily.
- Significant gender differences observed: boys averaged 56.8 min/day MVPA vs. girls at 43.0 min/day.
Conclusions:
- A substantial proportion of 4-year-olds exhibit high sedentary time and fail to meet PA recommendations.
- Low PA levels at this early age are concerning due to links with childhood obesity and reduced long-term health benefits.
- Intervention strategies promoting PA in early childhood are warranted.
Background:
Levels of physical activity (PA) affect health already at 4 years of age. The aims of this study were to describe levels and patterns of PA and sedentary time (ST) in a sample of 4-year-old Swedish children and to assess the number of children achieving PA guidelines throughout the week.
Methods:
Data from 540 4-year-old children enrolled in the population-based PRIMROSE trial was used. PA was measured for a period of 1 week by the Actigraph GT3X+ accelerometer. Average PA, time spent in light PA, moderate-to-vigorous PA (MVPA) and ST were assessed.
Results:
On average children spent 6.7% of the day in MVPA and 45% of the day being sedentary and 33% (n = 178) of the children met the PA guidelines of 60 minutes of MVPA per day. Boys spent 56.8 (SD 21.8) minutes/day in MVPA, while girls spent 43.0 (SD 18.1) minutes/day in MVPA (P < .001).
Conclusions:
Four-year-old children spent almost half of the day being sedentary and only one-third meet the recommended PA guidelines. This finding is alarming as higher levels of PA, already at 4 years of age, seem to reduce the risk of childhood obesity and provides long-term health benefits.
