Insights
This study establishes peak expiratory flow (PEF) reference values for children in Xinjiang. PEF can be accurately calculated using a child's height and sex.
Area of Science:
- Pediatric pulmonology
- Respiratory physiology
- Public health research
Context:
- Establishing normative data for lung function is crucial for diagnosing respiratory conditions in children.
- Regional variations in anthropometric and physiological parameters necessitate localized reference values.
Purpose:
- To determine reference values for peak expiratory flow (PEF) in a healthy pediatric population in Xinjiang, China.
- To identify key factors influencing PEF in children aged 7–16 years.
Summary:
- A cross-sectional study measured peak expiratory flow (PEF) in 3520 healthy children (7–16 years) in Xinjiang.
- PEF demonstrated significant positive correlations with age, height, and weight.
- A regression equation was derived: PEF = -342.98 + 3.94 * Height + 26.30 * Sex.
Impact:
- Provides essential reference data for pediatricians and healthcare providers in Xinjiang for accurate PEF assessment.
- Enables better diagnosis and monitoring of obstructive and restrictive lung diseases in children within the region.
- Highlights the importance of considering height and sex for precise PEF calculations in pediatric populations.
Objective:
To establish reference values of peak expiratory flow (PEF) for children in Xinjiang.
Methods:
A total of 3520 healthy children (1705 males and 1815 females) aged from 7 to 16 years were enrolled in this study. PEF was measured using MicroPeak Peak Flow Meter. Children's age, sex, height and weight were recorded. Impact factors for PEF were investigated by multiple stepwise regression analysis.
Results:
PEF values increased with the increase of age, height and weight and correlated significantly with age, height, weight and sex. The regression equation between sex and height and PEF was obtained, i.e, PEF (y)=-342.98+3.94 x Height (x1) + 26.30 x Sex (x2).
Conclusions:
PEF values can be calculated according to children's height and sex.

Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
