Resumen
La prevalencia de asma infantil aumentó significativamente de 1981 a 1988, principalmente en niños blancos. Sin embargo, la gravedad del asma y el impacto funcional no empeoraron durante este período.
Área de la Ciencia:
- Salud Pediátrica en la Salud Pediátrica.
- Epidemiología La epidemiología.
- Salud Pública La salud pública.
Sus antecedentes:
- El asma infantil es una preocupación significativa para la salud pública.
- Comprender las tendencias en la prevalencia y el impacto es crucial para las intervenciones efectivas.
Objetivo del estudio:
- Analizar los cambios en la prevalencia y distribución del asma infantil entre 1981 y 1988.
- Investigar la relación entre el asma infantil y la salud y el funcionamiento de los niños durante este período.
Principales métodos:
- Análisis de los datos de los Suplementos de Salud Infantil a la Encuesta Nacional de Entrevistas de Salud.
- Utilizó una muestra aleatoria nacionalmente representativa de niños de 0 a 17 años en 1981 y 1988.
Principales resultados:
- La prevalencia de asma infantil aumentó del 3,1% en 1981 al 4,3% en 1988 (P < .0001).
- El aumento se observó en los niños blancos, mientras que la prevalencia se mantuvo estable en los niños negros, aunque más alta en general.
- Los niños con asma en 1988 mostraron un mejor estado de salud y una reducción de hospitalizaciones, días en cama y días perdidos en la escuela en comparación con 1981.
Conclusiones:
- La prevalencia de asma infantil aumentó casi un 40% entre 1981 y 1988, exclusivamente entre los niños blancos.
- No hay evidencia que respalde un aumento en la gravedad del asma o el impacto funcional para los niños con asma durante este período de tiempo.
- Los hallazgos desafían las creencias sobre el aumento de la prevalencia del asma en los niños negros y el empeoramiento de la gravedad en los Estados Unidos.

01:20Assessment of Ventilation I: Respiratory Rate
Assessment of Ventilation
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.

01:26Respiratory Volumes and Capacities I
Assessing the respiratory rate and rhythm for a complete minute is crucial for evaluating the breathing pattern. Even a minor increase in the patient's average respiratory rate, by as little as three to five breaths per minute, is an early and vital indicator of respiratory distress. Patients with a respiratory rate exceeding twenty-four breaths per minute require close monitoring to determine the physiological alterations. This careful observation is essential for prompt recognition and...
01:17Pulmonary Cycle: Exhalation
In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...
01:17Other Pulmonary Disorders
Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.
01:25Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.
Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

01:29Respiratory Syncytial Virus Disease
Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
