From antiquity to the 1920s, the frequency of asthma and especially death from asthma was considered to be rare. In fact, asthma was not considered a significant cause of death during the early years of the 20th century. The Frenchman Armand Trousseau declared in his Clinique Medicale that "asthma n'est pas fatale" ("asthma is not fatal"). In the United States, Oliver Wendell Holmes had described asthma as a "slight ailment that promotes longevity." Clearly this perception of asthma has changed for many reasons.
Vitamin D has received tremendous amount of attention recently due to the ever-increasing reports of association between vitamin D deficiency and a wide range of conditions, from cancer to fertility to longevity. The fascination of disease association with vitamin D deficiency comes from the relatively easy solution to overcome such a risk factor, that is, either by increase in sun exposure and/or diet supplementation.
Asthma is the most common chronic disease of childhood, affecting millions of children in the United States and worldwide. Prematurity is a risk factor for asthma, and certain ethnic or racial minorities such as Puerto Ricans and non-Hispanic blacks are disproportionately affected by both prematurity and asthma.

BACKGROUND: While previous studies of enrollment motivation have been conducted with either healthy subjects or subjects with certain other diseases, little is known about the motives of subjects with asthma or rhinitis symptoms who seek to enter clinical trials. OBJECTIVE: This study was conducted to assess the self-reported role that altruism, healthcare receipt, and financial gain play in the motivation of subjects with symptoms of bronchial asthma, seasonal allergic rhinitis, and perennial nonallergic rhinitis who attempted to enroll in clinical trials.
OBJECTIVE: To analyse the motivations and perceptions of parents on the participation of their infants and young children in a comprehensive and invasive clinical research study. METHODS: Semistructured qualitative interviews were conducted with 23 mothers with asthma whose infants and young children were participating in the Copenhagen Prospective Study on Asthma in Childhood. The interviews were audiotaped, transcribed and analysed using the template analysis method.
