Abstract [en]

Background: Global industrialisation and economic development lead to changes in physical activity patterns with more sedentary behaviours and increasing sitting time, which are related to obesity. This study aims to identify the association between sedentary behaviour and obesity among older people aged 50+ in six low- and middle-income countries.

Methods: This study utilises data from the WHO's Study on Global Ageing and Adult Health in China, Ghana, India, Mexico, the Russian Federation and South Africa. Physical activity level was measured using the Global Physical Activity Questionnaire Version 2 and daily sitting time was recorded in hour. Overweight and obesity was measured through height and weight, with BMI > =25. We conducted logistic regression to analyse the association between physical activity level and total daily sitting time and obesity, controlling for age, sex, highest education level, and living area.

Results: Overweight and obesity prevalence ranged from 14% in India to 76% in the Russian Federation, and was significantly higher among women. The prevalence of low-to-moderate physical activity ranged from 36% in Ghana to 76% in South Africa. About 25% of the Russian population sat 2 hours or less daily, in contrast to 83% of the Mexican population who did so. Sitting more than 2 hours a day increased the odds of overweight and obesity (odds ratio 1.18; 95% confidence interval 1.09-1.29). The associated odds were 1.21 (95%CI 1.08-1.35) and 1.41 (95%CI 1.27-1.56) for those with moderate and low physical activity, compared to those who were more active.

Conclusions: Independent of physical activity level during work, leisure and transport, longer daily sitting time is significantly associated with obesity among older adults. Public health intervention to promote physical activity among older people is crucial in preventing premature chronic disease deaths and promoting active and healthy ageing.

Key messages:

  • The levels of sedentary behaviours among older people in low-and middle-income country are worrying, and are significantly associated with the level of obesity.
  • Reducing sitting time and promoting physical activity among older people are essential strategies to prevent obesity and its impacts on chronic disease and ensuring an active and healthy ageing.
