BACKGROUND: Insufficient physical activity (PA) is a major risk factor for non-communicable diseases (NCDs) and one of the leading causes of premature mortality worldwide. This study examined the prevalence and independent determinants of insufficient PA among adults resident of Tehran utilizing Tehran Cohort Study Data (TeCS).
METHODS: We used the recruitment phase data from the TeCS with complete data on PA. PA was assessed through a Likert-scaled question and categorized into three groups. Utilizing data from the 2016 national census, the age- and sex-weighted prevalence of insufficient PA in Tehran was determined. The adjusted logistic regression model is used to neutralize influencing factors and determine the factors associated with insufficient PA.
RESULTS: The weighted prevalence of insufficient PA was 16.9% among the 8213 adult citizens of Tehran, with a greater prevalence among females (19.0% vs. 14.8% among males). Additionally, older age groups, unemployed, housewives, and illiterate educated participants displayed a much higher prevalence of insufficient PA (p < 0.001). Moreover, Tehran\'s central and southern districts had higher rates of insufficient PA. Concerning the adjusted regression model, older age (Odds ratio [OR]: 4.26, 95% confidence interval [95% CI]: 3.24-5.60, p < 0.001), a lower education level (p < 0.001), unemployment (OR: 1.80, 95% CI: 1.28-2.55, p = 0.001), being a housewife (OR: 1.44, 95% CI: 1.15-1.80, p = 0.002), higher body mass index (BMI) (OR for BMI > 30: 1.85, 95% CI: 1.56-2.18, p < 0.001), opium consumption (OR: 1.92, 95% CI: 1.46-2.52, p < 0.001), diabetes mellitus (OR: 1.25, 95% CI: 1.06-1.48, p = 0.008), hypertension (OR: 1.29, 95% CI: 1.11-1.50, p = 0.001), and coronary artery diseases (OR: 1.30, 95% CI: 1.05-1.61, p = 0.018), were significantly associated with insufficient PA.
CONCLUSIONS: The identified associated factors serve as a valuable guide for policymakers in developing tailored intervention strategies to address the needs of high-risk populations, particularly among older adults and females.

The global prevalence of insufficient physical activity (PA) was reported to be 27.5% in 2016, and there were stable levels of insufficient PA worldwide between 2001 and 2016. The global target of a 10% reduction in insufficient PA by 2025 will not be met if the trends remain. The relevant data for trends in China were still scarce. This study aimed to determine nationwide temporal trends in insufficient PA among adults in China from 2010 to 2018.
645 903 adults aged 18 years or older were randomly selected from four nationally representative cross-sectional surveys of the China Chronic Disease and Risk Factor Surveillance conducted in 2010, 2013, 2015, and 2018. PA was measured using the Global Physical Activity Questionnaire. Temporal changes in insufficient PA prevalence and participation of domain-specific moderate- to vigorous-intensity PA (MVPA) were analyzed using logistic regression.
From 2010 to 2018, the age-adjusted prevalence of insufficient PA in China increased from 17.9% (95% confidence interval 16.3% to 19.5%) in 2010 to 22.3% (20.9% to 23.8%) in 2018 (P for trend < 0.001). By age group, with a significant increase in insufficient PA in adults aged 18-34 years (P for trend < 0.001), which rose more rapidly than in adults aged ≥ 35 years (P for interaction < 0.001). Insufficient PA has increased significantly among adults engaged in agriculture-related work, non-manual work, and other manual work (all P for trend < 0.05). And among the occupational groups, those engaged in agriculture-related work had the fastest increase (P for interaction = 0.01). The percentage of adults participating in work-related MVPA decreased from 79.6% (77.8% to 81.5%) to 66.8% (64.9% to 68.7%) along with a decrease in time spent on work-related MVPA, while percentages of adults participating in recreation-related MVPA increased from 14.2% (12.5% to 15.9%) to 17.2% (16.0% to 18.4%) (all P for trend < 0.05).
Among Chinese adults, an increasing trend was found in insufficient PA from 2010 to 2018, with more than one-fifth of adults failing to achieve the recommendation of adequate PA. More targeted PA promotion strategies should be developed to improve population health.

Globally, school-going children spend most of their days at school, sitting in lessons and unable to achieve the daily WHO recommendations for Physical Activity (PA) of at least 60 minutes per day. Limited studies have assessed the opportunities schools provide for PA to help the children achieve their daily recommended PA. We determined the level of and the factors associated with PA offered in primary schools in Makindye Division in Kampala during the school term.
This cross-sectional study was conducted in 36 selected government and private primary schools in Makindye Division, Kampala. PA was defined as the amount of time in minutes available for PA as per WHO recommendations - sufficient (60 minutes or more of PA) or insufficient (less than 60 minutes of PA) and assessed for any factors associated with provision of time for PA in schools. Data were collected by interview administered questionnaires and analysed descriptively. Factors associated with PA were assessed using a logistic regression model.
Of the 36 schools, 3 were government and 33 were private schools. The proportion of schools offering sufficient time for PA among Primary schools in the Makindye Division was (8/36) 22%. The average time for PA for all schools per week was 197 minutes (SD 70.7). Sufficient PA was associated with the provision of PE lessons after a break or after lunch (p-value 0.038). Sufficient PA was more likely in schools that offered volleyball (OR 8.69), had space in the school for PA (OR 13.27), provided athletics (OR 2.26) and whose fees were Ushs 700,000 (USD 187) or more (OR 1.30).
Only 22% of sampled schools offered sufficient time for PA among Primary schools in Kampala per WHO guidelines. Provision of sufficient time for PA was associated with PE scheduled either after break or lunch. Sufficient PA was more likely with schools that had space for PA, schools which offered volleyball and athletics, and whose fees were 700,000/= or more. Schools should consider scheduling PE lessons after break or after lunch to increase the likelihood of meeting the targeted time for PA. Primary schools need to be supported to establish facilities and to increase diversity in available activities to ensure children achieve their recommended PA.

Low level of physical activity (PA) has become an important public health problem even in low-income countries. The objectives of this study were to measure PA levels, determine the prevalence of low PA and identify socio-demographic factors associated with it in Bangladeshi adults.
Data from 792 (urban, 395; rural, 397) Bangladeshi adults (25-64 years) were included in this population-based cross-sectional study conducted in 2011. Global Physical Activity Questionnaire version 2 (GPAQ-2) was used to measure PA. The metabolic equivalent task (MET) in minutes per week was calculated to determine total PA. Participants were categorized into low, moderate and high PA groups. Logistic regression was used to assess socio-demographic factors associated with low level of PA.
Median MET-minute of total PA per week was almost double in the rural area (1720) than the urban area (960). The overall prevalence of low PA was 50.3% (95% CI: 46.8-53.8), urban 59.5% (54.7-64.3) and rural 41.9% (37.0-46.8). Women in general were more inactive (women 63.1% [58.3-67.9], men 39.3% [34.6-44.0]). The main contributions to total PA were from work (urban 40.0%, rural 77.0%) and active commute (57.0%, 21.0%). Leisure-time PA represented a very small proportion (<3.0%). Multiple logistic regressions found a significant association of urban residence (OR = 2.2; 95% CI: 1.5-3.2), women (2.1; 1.4-3.9), oldest age group 55-64 years (15.6; 7.5-32.2) compared to youngest age group 25-34 years, graduation or further education (8.6; 4.1-17.7), and higher socio-economic class (2.4; 1.4-4.2) compared to poor with insufficient PA.
This study identifies low PA in a rural and urban population in Bangladesh and that further large-scale population studies are warranted.
