Worldwide trends in insufficient physical activity from 2001 to 2016: a pooled analysis of 358 population-based surveys with 1·9 million participants

TLDR

Insufficient physical activity is a leading risk factor for non‑communicable diseases and negatively impacts mental health and quality of life. The study aims to describe country‑level levels of insufficient physical activity and estimate global and regional trends by pooling data from population‑based surveys. The authors pooled 358 surveys from 168 countries (1.9 million participants), adjusted data to a standard definition and age groups using regression models, and estimated time trends with multilevel mixed‑effects modelling. In 2016 the global age‑standardised prevalence of insufficient physical activity was 27.5 %, higher in women (31.7 %) than men (23.4 %), remained stable since 2001, and varied markedly by region and income, with high‑income countries showing twice the prevalence of low‑income countries and a rising trend that threatens the 2025 target.

Abstract

Insufficient physical activity is a leading risk factor for non-communicable diseases, and has a negative effect on mental health and quality of life. We describe levels of insufficient physical activity across countries, and estimate global and regional trends.We pooled data from population-based surveys reporting the prevalence of insufficient physical activity, which included physical activity at work, at home, for transport, and during leisure time (ie, not doing at least 150 min of moderate-intensity, or 75 min of vigorous-intensity physical activity per week, or any equivalent combination of the two). We used regression models to adjust survey data to a standard definition and age groups. We estimated time trends using multilevel mixed-effects modelling.We included data from 358 surveys across 168 countries, including 1·9 million participants. Global age-standardised prevalence of insufficient physical activity was 27·5% (95% uncertainty interval 25·0-32·2) in 2016, with a difference between sexes of more than 8 percentage points (23·4%, 21·1-30·7, in men vs 31·7%, 28·6-39·0, in women). Between 2001, and 2016, levels of insufficient activity were stable (28·5%, 23·9-33·9, in 2001; change not significant). The highest levels in 2016, were in women in Latin America and the Caribbean (43·7%, 42·9-46·5), south Asia (43·0%, 29·6-74·9), and high-income Western countries (42·3%, 39·1-45·4), whereas the lowest levels were in men from Oceania (12·3%, 11·2-17·7), east and southeast Asia (17·6%, 15·7-23·9), and sub-Saharan Africa (17·9%, 15·1-20·5). Prevalence in 2016 was more than twice as high in high-income countries (36·8%, 35·0-38·0) as in low-income countries (16·2%, 14·2-17·9), and insufficient activity has increased in high-income countries over time (31·6%, 27·1-37·2, in 2001).If current trends continue, the 2025 global physical activity target (a 10% relative reduction in insufficient physical activity) will not be met. Policies to increase population levels of physical activity need to be prioritised and scaled up urgently.None.
