Life in a New Normal with a Self-Care Routine: A Cross-Sectional Study of Older Adults' Daily Health Behaviors (DHB) Performance during the Initial Outbreak of COVID-19 in China.

For older adults, self-care begins with daily health behaviors (DHB), which refers to a series of basic behaviors beneficial to health in daily life; it is the foundation for promoting health, preventing disease, and maintaining health with or without the support of a healthcare provider. Thus, this study aimed to observe the changes in DHB among older adults when the COVID-19 pan-demic first erupted in China (at the beginning of 2020) and explore the impact factors on self-care routines in daily life. We applied a cross-sectional study among 1256 (83.7%) valid older Chinese from 19 February 2020 to 19 March 2020, the score of DHB changes (mean ± SD, 14.70 ± 2.140; range, 8-18) presented a significant growth (t 1256 = 44.636, p < 0.001) during COVID-19. From 3 hierarchical linear regression models, the older Chinese who received a higher education include high school ( β = 0.403, 95% CI [0.009, 0.797], p = 0.045) and college degree and above ( β = 0.488, 95% CI [0.034, 0.943], p = 0.035), and lived in the eastern China ( β = 0.771, 95% CI [0.392, 1.151], p < 0.001) took DHB more frequently. However, the high-risk infection ( β = -0.740, 95% CI [-1.248, -0.231], p = 0.004), overweight/obese character ( β = -0.265, 95% CI [-0.526, -0.004], p = 0.047), and alcohol consumption ( β = -0.350, 95% CI [-0.634, -0.065], p = 0.016) are significant factors in decreasing a senior's DHB performance. For China, self-care offers a straightforward strategy among the range of measures required to combat COVID-19 and future health threats. In summary, findings in this study can build a foundation for developing healthcare policy and services for the relevant government and departments on prompting DHB and the importance of self-care among the older population.
