Seasonal Variability in Weight Gain Among American Indian, Black, White, and Hispanic Children: A 3.5-Year Study.

American journal of preventive medicine·2021

Young adults did not change their physical activity (PA) behavior when wearing motion sensors. Differences in daily activity were due to typical weekday versus weekend patterns, not sensor reactivity.

Area of Science:

  • Exercise Science
  • Behavioral Science
  • Biomedical Engineering

Background:

  • Assessing physical activity (PA) is crucial for understanding health behaviors.
  • Motion sensors like accelerometers and pedometers are common tools for objective PA measurement.
  • Understanding potential reactivity to these devices is important for data validity.

Purpose of the Study:

  • To investigate if young adults alter their physical activity (PA) behavior when wearing motion sensors.
  • To determine if wearing accelerometers and pedometers influences PA patterns in young adults.
  • To assess PA reactivity in a sample of young adults over a two-week period.

Main Methods:

  • 119 young adults (mean age = 20.82 years) participated over two consecutive weeks.

  • Week 1: Participants wore an accelerometer; Week 2: Participants wore an accelerometer and a pedometer.
  • Data analyzed using descriptive statistics and two-factor repeated-measures ANOVA, examining daily counts and steps.

    • Main Results:

    • Significant differences in daily activity counts were observed across study days in both weeks (p < .0001).
    • Significant differences in daily steps were found during Week 2 (p < .0001).
    • No evidence of reactivity to the motion sensors was detected; differences were attributed to weekday/weekend activity variations.

    Conclusions:

    • Young adults did not exhibit reactivity to wearing accelerometers and pedometers.
    • Observed daily PA variations were primarily driven by typical weekday versus weekend behavior.
    • Motion sensors appear to be valid tools for measuring PA in this demographic without inducing behavioral changes.
