Abstract

Background:

Asthma prevalence in adolescents appears to be increasing and determinants are not well established.

Objective:

To determine the association between sex and active smoking with asthma prevalence in adolescents.

Participants And Method:

In this cross-sectional study 6,922 students, ages 12 to 18 years, residents in an area of northeastern Mexico, were included. We developed a questionnaire based on The International Study of Asthma and Allergies in Childhood (ISAAC) and on The European Community Respiratory Health Survey (ECRHS). The association between sex and active smoking with asthma prevalence was determined using a logistic regression model.

Results:

Of the total population, 46.3% were males, 7.3% suffered from asthma and 17.3% were cigarette smokers. We found that sex (OR = 0.55; CI 95%: 0.48-0.63) and active smoking (adjusted OR = 1.12; CI 95%: 0.89-1.42) were not associated with asthma prevalence. Females (OR = 1.44; CI 95%: 1.13-1.84) and active smoking (adjusted OR = 1.38; CI 95%: 1.15-1.67) were associated with prevalence of wheezing in the last 12 months, and with prevalence of dry cough at night (OR = 1.53; CI 95%: 1.34-1.76).

Conclusions:

Teenager males and active smoking were not associated with asthma prevalence. Females had an association with wheezing in the last 12 months and dry cough at night.

Asthma-I: Introduction

Asthma-I: Introduction

Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Asthma III: Clinical Manifestations

Asthma III: Clinical Manifestations

Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...

Asthma-III: Symptoms and Complications

Asthma-III: Symptoms and Complications

Asthma, a common chronic respiratory condition, is classified considering the frequency and severity of symptoms alongside lung function impairment. Understanding this classification is essential for appropriate treatment and management. Here's a detailed look at the classification of asthma and its clinical features and complications:

Asthma-IV: Diagnostic and Management

Asthma-IV: Diagnostic and Management

The diagnosis and management of asthma are comprehensive, encompassing clinical assessments, lung function tests, and pharmacological interventions. Here's an overview:

This is the first step in diagnosing and managing asthma. It includes:

Asthma I: Introduction

Asthma I: Introduction

Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...

Asthma-II: Pathophysiology and Classification

Asthma-II: Pathophysiology and Classification

Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
