Maturational delay and temporal growth retardation in asthmatic boys

Insights

Asthmatic boys experience delayed growth and sexual maturation. This study found growth retardation during childhood and adolescence, with a delayed adolescent growth spurt, suggesting factors related to asthma impact development.

Area of Science:

  • Pediatric Endocrinology
  • Respiratory Medicine
  • Human Growth and Development

Background:

  • Asthma is a common chronic respiratory disease in children.
  • Growth and pubertal development can be affected by chronic illnesses.
  • Understanding these effects in asthmatic boys is crucial for clinical management.

Purpose of the Study:

  • To analyze growth patterns in height, bone age, and sexual maturation in asthmatic boys.
  • To identify specific age periods of growth retardation and pubertal delay.
  • To investigate the relationship between asthma and developmental delays.

Main Methods:

  • Mixed-longitudinal analysis of height measurements in 531 asthmatic boys (ages 2-20).
  • Mixed-longitudinal analysis of bone age in 370 asthmatic boys.
  • Cross-sectional analysis of pubic hair development in 91 asthmatic boys.

Main Results:

  • Height growth showed no infancy retardation, slight childhood retardation, and pronounced adolescent delay.
  • The adolescent growth spurt was delayed by approximately 1.3 years.
  • Bone age was slightly retarded between ages 6-13, and pubic hair development was significantly delayed.
  • Factors secondary to asthma appear to cause growth and developmental retardation.

Conclusions:

  • Asthmatic boys exhibit a characteristic pattern of delayed growth and sexual maturation.
  • These delays are linked to physiological maturation issues secondary to the asthmatic condition.
  • Further research is needed to elucidate the specific mechanisms and optimize interventions.

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience, such as differences...

Asthma: Pathogenesis and Management

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
Signs of Puberty01:27

Signs of Puberty

Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...
Asthma I: Introduction01:28

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 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,...

Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features

Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...
