Results
In total, 1,156 units were visited and invited to participate in the survey.
There were 707 (61.2 %) units either not at home or not responsive, even on second attempt.
Out of the 1,156 units, 240 units (20.8 %) consented and completed the survey, and 18 % rejected participation in
the survey.
The median age of the participants was 41.5 years old [Interquartile range (IQR): 32–52], 50.8 % was female, 76.7 % was married, 66.3 % was Chinese, 75.8 % was Singaporean, and 55.4 % stayed in a four room flat (Table 1).
In addition, 50 % of the participants had post-secondary education (defined as higher than
GCE ‘O’ level), 40 % had at least one comorbidity, and the most common comorbidity was hypertension(14.2%;Table1).
The majority of the participants (60.4 %) had three to five residing members, and 22.9 % had at least a
child below the age of five.
Furthermore, 25 % of the participants self-reported having at least one diarrhoea episode in the past six month period before the survey day, and about 30 % self-reported having at least one flu episode over the same period (Table 1). The sampled population had similar demographic profiles as the national population (Table 1).
