Insights

Passive smoking negatively impacts lung function in late-preterm children. This study found increased airway resistance in preschool children exposed to secondhand smoke, highlighting risks to pulmonary health.

Area of Science:

  • Pediatric Pulmonology
  • Environmental Health
  • Neonatal Medicine

Background:

  • Late-preterm delivery (34-36 weeks gestation) is linked to impaired lung development.
  • Passive smoking (exposure to secondhand smoke) is a known environmental risk factor for respiratory issues in children.

Purpose of the Study:

  • To investigate the impact of passive smoking on lung function in preschool children born late-preterm.
  • To utilize impulse oscillometry (IOS) as a noninvasive tool for assessing pulmonary function.

Main Methods:

  • A cohort of 139 late-preterm children (3-7 years) was divided into passive smoking (PS) and non-PS groups.
  • Lung function was assessed using impulse oscillometry (IOS), measuring resistance (R5-R20) and reactance (X5-X20) at 5-20 Hz.

Main Results:

  • Children exposed to passive smoking (PS group) exhibited significantly higher median peripheral airway resistance (R5-R20) compared to the non-PS group.
  • A significant decrease in median reactance (X10) was observed in the PS group, indicating altered lung mechanics.

Conclusions:

  • Passive smoking exposure is associated with increased peripheral airway resistance in late-preterm born children.
  • Secondhand smoke adversely affects lung function in this vulnerable pediatric population, underscoring the need for avoidance.

Levels of Health Promotion and Illness Prevention

Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...

Models of Health Promotion and Illness Prevention I

A model is a theoretical way to understand a concept or an idea. Models can overcome barriers to health regardless of diverse economic and cultural backgrounds. In addition, models make the task easier by providing different ways to approach complex issues. There are two major health promotion models: the health belief model and the health promotion model.
The health belief model (HBM) attempts to predict health-related behavior in specific belief patterns. According to the HBM, a person's...

Models of Health Promotion and Illness Prevention II

The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.
The agent-host-environment model states that disease results...

Pulmonary Function Tests

Pulmonary Function Tests (PFTs)
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.
PFTs involve using a spirometer, a...

Passive Filters01:27

Passive Filters

Passive filters are utilized to shape the frequency spectrum of signals across a diverse array of applications. These filters, using only passive elements like resistors (R), inductors (L), and capacitors (C), are capable of selectively allowing or blocking certain frequency ranges without the need for external power sources.
Low-Pass Filters
Low-pass filters are designed to transmit signals with frequencies lower than the cutoff frequency, ωc, and attenuate those above it. The cutoff...
