Physical activity during COVID-19 lockdown: relationship with sedentary behaviour, health-related quality of life, loneliness, and sleep quality among a sample of Nigerian adults

ABSTRACT

COVID-19 lockdown, targeted at preventing the spread of coronavirus, had deleterious effects on physical and psychosocial health. This study examined the association between physical activity (PA), sedentary behaviour, health-related quality of life (HRQoL), loneliness and quality of sleep of 507 Nigerian adults during the COVID-19 lockdown. Five hundred and seven respondents (aged 18-67 years) from 12 States completed an online survey on RedCap. Questionnaires comprising the Stages of Change scale, Pittsburgh Sleep Quality Index, International Sedentary Assessment Tool, UCLA Loneliness Questionnaire, Short Form-12 Health Survey, and International Physical Activity Questionnaire were used. Respondents were categorised based on exercise behaviour as non-exercisers, non-regular exercisers, or regular exercisers;and based on age into 18-24, 25-34, 35-44 and > 44 years categories. Descriptive and inferential statistics were used to analyse the data. About 33.1% of respondents did not meet moderate-to-vigorous PA levels. The physical component of HRQoL was positively associated with total PA (p = 0.04). Among the non-exercisers, the odds of being regular exercisers during pre-COVID-19 lockdown were significantly higher for the 35-44 (odds ratio [OR] = 3.49;95% CI = 1.44, 8.48, p = 0.01) and > 44 years age groups (OR = 2.98;95% CI 1.16, 7.62, p = 0.02) relative to 18-24 years age category. During COVID-19 lockdown, > 44 (OR = 3.65;95% CI 1.47, 9.07, p = 0.005), 35-44 (OR = 6.42;95% CI 2.75, 14.96, p = 0.001) and 25-34 (OR = 2.35;95% CI 1.15, 4.80, p = 0.02) years age categories had significant higher odds of being regular exercisers compared to the 18-24 years age group. There was a high rate of physical inactivity among Nigerian adults during the COVID-19 lockdown, which was directly influenced by the physical components of HRQoL. Older age was an independent predictor of exercise behaviour before and during the COVID-19 lockdown among Nigerian adults.
