Knowledge, attitudes, practices, and its associated factors toward COVID-19 pandemic among Bangladeshi older adults

Background: The newly emerged COVID-19 has an unprecedented impact on all classes of people, particularly the elderly. The knowledge, attitudes, and practices (KAP) of older adults toward COVID-19 are currently unknown. This study aimed to investigate the KAP and its associated factors toward COVID-19 among older adults in Bangladesh. Methods: A cross-sectional survey was conducted from April to May 2021 among Bangladeshi older adults. Face-to-face interviews were used to collect data from five selected divisions in Bangladesh using simple random sampling. The questionnaire consisted of socio-demographic characteristics, disease conditions, and KAP toward COVID-19. Descriptive statistics, t-tests, one-way analysis of variance (ANOVA), and logistic regression analyses were performed. Results: Out of 900 respondents, the majority of older adults (82.9%) indicated that COVID-19 is a viral disease and the major clinical symptom of COVID-19 (86.5%). Only 22.1% of participants always washed their hands with soap or hand sanitizer, and 27.6% wore a mask to protect against the virus when going outside the home. Overall, 55.2% had adequate knowledge, 50.2% had positive attitudes toward COVID-19 and only 22.7% had good practices. Out of 30 scores, mean score values were 20.8±6.7 in the knowledge section, 21.2±4.3 in the attitude section, and 11.3±6.7 in the practice section out of 30. In binary logistic regression analysis, factors associated with poor knowledge, and practices were being male, aged >70 years, having a primary education, less income
