“…Previous research [ 45 ] indicates that sedentary behaviour has not been studied in the African culture. This study concurs with research from Western countries which indicate a high prevalence of sedentary behaviour among adolescents in todays society [ 46 , 47 ]. The present study found that sedentary behaviour among Ghanaian young people was mainly associated with screen use, especially computers, followed by television and videogames.…”

BackgroundResearch development is needed in physical activity and sedentary behaviour and their associations with mental health in young people. In Western countries the weather is a key contributing factor of sedentary behaviour in youth. The likely contributing factor of sedentary behaviour among African youth has not been explored. This study examined the association between sedentary behaviour and mental health in African young people.MethodsParticipants were 296 adolescents (150 males, 146 females) aged 13 to 18 years (mean = 14.85 years) living in Ghana. Participants’ physical activity levels were assessed using the Physical Activity Questionnaire for Older Adolescents (PAQ-A) and sedentary behaviour, using the Adolescents Sedentary Activity Questionnaire. Depression was assessed using the Children Depression Inventory and aspects of self-esteem were measured with the Physical Self-worth test and Body Image Silhouette test.ResultsThere was a significant negative correlation between physical activity and mental health independent of sedentary behaviour [depression (r =-0.78, p < 0.001); physical self-worth (r = 0.71, p < 0.001); body dissatisfaction (r =-0.76, p < 0.001)]. Moreover, sedentary behaviour was significantly associated with higher depression (r = 0.68, p < 0.001). Affluence was a significant contributing factor of sedentary behaviour in African young people [t (294) =-7.30, p < 0.001].ConclusionThe present study has found that sedentary behaviour is highly prevalent among African adolescents especially among adolescents from affluent homes. Low levels of physical activity as well as sedentary behaviour is significantly associated with mental health problems among African youth, which is consistent with reports from studies among Western young people. The present research, therefore, contributes new information to the existing literature. Increased physical activities can improve the mental health of adolescents.

“…A high prevalence of overweight and obesity (≈46%) was found among Portuguese children in this study which is not in complete agreement with previous studies. For example, Vasques et al (2012) found a prevalence of about 30% in children and adolescents aged 6 to 13 years using the IOTF cut points [ 47 ]. Sardinha et al (2011) studied Portuguese youth aged 10 to 18 years, and reported the prevalence of overweight and obesity contrasting two cut points 22.7% and 31.7% using the IOTF and WHO references, respectively.…”

Profiling Physical Activity, Diet, Screen and Sleep Habits in Portuguese Children

Obesity in children is partly due to unhealthy lifestyle behaviours, e.g., sedentary activity and poor dietary choices. This trend has been seen globally. To determine the extent of these behaviours in a Portuguese population of children, 686 children 9.5 to 10.5 years of age were studied. Our aims were to: (1) describe profiles of children’s lifestyle behaviours; (2) identify behaviour pattern classes; and (3) estimate combined effects of individual/socio-demographic characteristics in predicting class membership. Physical activity and sleep time were estimated by 24-h accelerometry. Nutritional habits, screen time and socio-demographics were obtained. Latent Class Analysis was used to determine unhealthy lifestyle behaviours. Logistic regression analysis predicted class membership. About 78% of children had three or more unhealthy lifestyle behaviours, while 0.2% presented no risk. Two classes were identified: Class 1-Sedentary, poorer diet quality; and Class 2-Insufficiently active, better diet quality, 35% and 65% of the population, respectively. More mature children (Odds Ratio (OR) = 6.75; 95%CI = 4.74–10.41), and boys (OR = 3.06; 95% CI = 1.98–4.72) were more likely to be overweight/obese. However, those belonging to Class 2 were less likely to be overweight/obese (OR = 0.60; 95% CI = 0.43–0.84). Maternal education level and household income did not significantly predict weight status (p ≥ 0.05).

“…In Iranian adolescents, the time spent on TV viewing was associated with an increased risk of obesity while obesogenic foods and physical activity had no effect on the frequency of obesity 19 . In Portugal, only 12.2% of children spend 1.5 hours or less on TV and computer and boys who spend less time on TV and computer were 75.4% less likely to be overweight/obese than those who spend more time 20 . Indicators of sedentary lifestyle, such as screen time and presence of a TV in the child's bedroom, were associated with overweight and obesity in Norwegian schoolchildren 21 .…”

Background: Obesity is a health problem among adolescents worldwide and television (TV) viewing could promote it in several ways.Objective: To determine the association between time spent on TV viewing and obesity considering economic status and residential area in primary schoolchildren in the north of Iran. Method:A descriptive cross-sectional study was carried out on primary schoolchildren from 112 schools. Schools and students were chosen by cluster sampling. All children completed a questionnaire containing questions on the socio-economic condition. Overweight and obesity were classified based on the Centres for Disease Control and Prevention (CDC) values with body mass index (BMI) in excess of the 85th and 95th percentiles, respectively. Daily time spent on TV viewing was classified into 3 groups: less than 1 hour or no watching, 1-2 hours and 3 hours or over. SPSS 16.0 software was used for statistical data analysis.Results: Study population comprised 7,453 primary schoolchildren (urban 3,662, rural 3,791). Of the subjects 52.7% viewed TV for 3 hours or more. In boys, prevalence of obesity had a positive association with TV viewing time but in girls, it was not a steady trend. In urban areas, time spent on TV viewing was in line with obesity but wasting significantly decreased with more time spent on TV viewing (P=0.001). This association was not seen in rural children. In the poor economic group, prevalence of obesity significantly decreased with more time spent on TV viewing (P=0.041) but this trend was not found in the moderate economic group. In the good economic group, the association between obesity and time spent on the TV viewing was not significant.
