Background:The transition to young adulthood offers more autonomy in making lifestyle choices, many of which can be unhealthy. Lack of physical activity (PA) and prolonged sedentary behaviour (SB) can have adverse effects on the concurrent and future health and wellbeing of young adults. However, little is known about PA and SB among young adults in low-and-middle-income countries (LMICs), where rapid urban-industrial transformation may promote a sedentary lifestyle and affect wellbeing. Bangladesh is an LMIC with young adults representing one-fifth of the country's population. Major causes of poor health in this age group are attributed to non-communicable diseases and psychosocial disorders. Given the established associations with health and wellbeing, it is essential to understand PA and SB of young adults in Bangladesh.
Objectives:To assess the (i) prevalence and sociodemographic patterns of PA and SB, (ii) individual-level correlates of PA, SB, and changes in PA and SB, and (iii) associations of PA and SB with psychological distress and sleep difficulties among university-based young adults in Bangladesh. Design and Methods: A one-year prospective study with two assessment points was conducted to collect data. The self-administered written survey included the Global Physical Activity Questionnaire (GPAQ) to assess PA and SB. Wellbeing was assessed using the Kessler 6 Psychological Distress scale and a single item on sleep difficulties. Data on sociodemographic, health, wellbeing, lifestyle, and environmental factors were also collected.Setting/participants: Participants were undergraduate students aged 18 to 24 years from six universities (3 public and 3 private) in Dhaka city, Bangladesh (Wave 1=573; response rate 92%, 45% female; Wave 2=395).
Results:Overall, 17% of participants at Wave 1 and 23% at Wave 2 met the World Health Organization recommendations to do ≥150 mins/week of moderate-to-vigorous PA (MVPA). Significantly more males than females were meeting the recommendations at both waves (Wave 1: 27% vs. 6%; Wave 2: 34% vs. 12%). Median duration of MVPA was significantly higher (p<.0001) for males [120 mins/week] than females [90 mins/week].Jogging/running was the most common recreational PA, with 20% males and 12% females doing this at least once per week. Females participated more in indoor activities (e.g., University Library and, subject to the policy and procedures of The University of Queensland, the thesis be made available for research and study in accordance with the Copyright Act 1968 unless a period of embargo has been approved by the Dean of the Graduate School.
