Abstract
BackgroundPhysical inactivity and high sitting time are directly related to mortality and morbidity of non-communicable diseases (NCDs). Thus, improved understanding of the prevalence and trends of these behaviors could support the design of policies and interventions for NCDs prevention.ObjectiveTo determine the current prevalence of physical inactivity and high sitting time, to analyze the trends, and to estimate the association of meeting/not meeting physical activity recommendations and low/high sitting time with sociodemographic characteristics and body mass index categories.MethodologyData from the 2018 National Health and Nutrition Survey were used. Moderate-to-vigorous physical activity (MVPA) and sitting minutes per week were calculated using the International Physical Activity Questionnaire short form (IPAQ). In total, 38,033 questionnaires of adults aged 20 to 69-year-old were analyzed. Adults were classified as physically inactive if they achieved less than 150 minutes per week of MVPA and as with high sitting time if they accumulated more than 420 minutes of sitting per day. Health and Nutrition National Surveys (ENSANUT) 2006, 2012 and 2018 were used to estimate the trends.ResultsIn total, 16.5% were classified as physically inactive and 11.3% within the high sitting time category. Both prevalences increased more than 40% during the 12-y period (2006–2018). In 2018, men, younger adults, those living in urban areas, and people within the highest socioeconomical status and educational levels were more likely to not achieve physical activity recommendations and to be classified in the highest sitting time category.ConclusionTo stop current increased trends and achieve global targets, stronger and more concerted efforts to promote physical activity and reduce sitting time are required. Thus, continued surveillance of these behaviors is necessary.

Summary
Physical inactivity is associated with increased morbidity and mortality of many diseases including diabetes, hypertension, cancer, stroke and cardiovascular diseases [1, 2]. Physical inactivity is responsible for a substantial economic burden [3]. Based on the World Health Organization (WHO) recommendations, physical inactivity is defined as failing to accumulate at least 150 minutes of moderate physical activity or 75 minutes of vigorous physical activity or the combination of both intensities per week [4]. 27.5% of adults are classified as physically inactive [5]. Physical inactivity prevalence has not experienced a significant increase worldwide since 2001 [5]. Physical inactivity and high sitting time are directly related to mortality and morbidity of noncommunicable diseases (NCDs). Improved understanding of the prevalence and trends of these behaviors could support the design of policies and interventions for NCDs prevention
