An evaluation of asthma morbidity in Singaporean schoolchildren--a teachers' survey.

: Asthma is the most common chronic illness in childhood. This study evaluated the asthma morbidity among Singaporean schoolchildren. The survey involved 1,744 schoolteachers using a structured written questionnaire. 73.4% of class teachers reported at least 1 asthmatic student in their class. 37.1% of teachers had students absent from school for up to 3 days per month and 5.1% missed school for 4 to 14 days in a month. 87.4% of the physical education (PE) teachers reported at least 1 asthmatic student in their class. 65.2% reported an average of 1-3 students sitting out at each PE lesson and 15.1% reported students who were exempted from PE for more than 3 months in a year due to asthma. The morbidity of asthma in Singaporean schoolchildren in terms of school absenteeism and exemption from PE classes is substantial. The data supports a need to improve asthma control amongst our schoolchildren.
