OBJECTIVES The aim of this study was to analyse the clustering of multiple health-related behaviours among adolescents and describe which socio-demographic characteristics are associated with these patterns. DESIGN Cross-sectional study. SETTING Brazilian schools assessed by the National Survey of School Health (PeNSE, 2012). PARTICIPANTS 104 109 Brazilian ninth-grade students from public...

Abstract Background Most studies on day-to-day patterns of physical behaviours (i.e. activities and sedentary behaviour) are based adults with high socioeconomic status (SES) without differentiating between work leisure time. Thus, we aimed to characterise the time among low SES investigate influence behaviours. Methods This cross-sectional study included 963 from occupations (e.g. manufacturin...

BACKGROUND Sedentary behaviours (television, video and computer) are related to health outcomes independent of physical activity. Few studies have examined trends and correlates of sedentary behaviours among youth in developing nations. The current study is to examine temporal trends in sedentary behaviours and recent correlates of screen use in Chinese children during a period of economic tran...

BACKGROUND Physical activity and sedentary behaviour are important contributors to adolescents' health. These behaviours may be affected by the school and neighbourhood built environments. However, current evidence on such effects is mainly limited to Western countries. The International Physical Activity and the Environment Network (IPEN)-Adolescent study aims to examine associations of the bu...

Context Clustering of unhealthy lifestyle behaviours has been well documented. Addressing multiple behavioural issues at the same time presents a challenge for both practitioners and the clients they serve. This four-group randomised trial sought to examine the comparative impact of interventions focused on a combination of one aspect of dietary behaviour (low-fat diet or fruit and vegetable in...

The time that children and adults spend sedentary-put simply, doing too much sitting as distinct from doing too little physical activity-has recently been proposed as a population-wide, ubiquitous influence on health outcomes. It has been argued that sedentary time is likely to be additional to the risks associated with insufficient moderate-to-vigorous physical activity. New evidence identifie...

Sedentary behaviour is an independent risk factor for adverse health conditions. Adults with intellectual disabilities spend a high proportion of their day engaged in sedentary behaviour, however, there is limited evidence on potential correlates of objectively measured sedentary behaviour in this population group. In Glasgow, UK from July to September 2017, a secondary analysis of pooled basel...
