“…Nevertheless, our findings are consistent with that from a previous community-based sample of younger children. 15 A 5-year follow-up of this study is currently underway, which will provide longitudinal evidence on this association.…”

“…Additionally, each hour per day spent doing homework was associated with a 19% reduced odds of having high BP during early adolescence. Martinez-Gomez et al 15 recommended that time spent in TV viewing, computer use and total screen time should be considered independently. This is particularly important given that published studies show computer use and video game play could have differing metabolic and physiologic effects.…”

“…These findings are in agreement with previous studies conducted among children and adolescents. 15,17,18 Several mechanistic links between TV viewing and elevated BP in children have been hypothesized. Increased micronutrient and energy intake is one proposed mediator.…”

“…A recent US community-based study of 111 children aged 3-8 years reported a positive association between screen time (that is television (TV) viewing and computer use) with both systolic and diastolic BP, after adjusting for age, sex and percentage of body fat. 15 In a Belgian study of 1028 children aged 6-12 years, a borderline significant association was observed between TV viewing and systolic BP in boys but not girls. 16 In a Brazilian study of 4452 children aged 10-12 years, the authors reported a significant positive association between TV viewing and systolic and diastolic BP.…”

“…19 For effective prevention of hypertension and resulting cardiovascular morbidity and mortality, it is important to fully clarify the influence of a range of sedentary activities on BP in children. 15 Ours may be the first, large community-based study of children to assess the association between such a wide range of indicators of sedentariness (that is TV viewing, computer usage, video game usage and time spent in homework and reading) and BP, after adjusting for several potential confounders.…”

Relationship between a range of sedentary behaviours and blood pressure during early adolescence

Very few studies have explored links between physical activity, sedentary behaviours and blood pressure (BP) in early adolescence. We aimed to assess the association between a range of sedentary activities (screen time, television (TV) viewing, computer usage, video game usage and time spent in homework or reading) and BP in schoolchildren. Eligible year-7 students (2353/3144, mean age 12.7 years) from a random cluster sample of 21 Sydney schools were examined during [2003][2004][2005]. Parents and children completed detailed questionnaires of activity. BP was measured using a standard protocol and high BP was defined using published guidelines. Height and weight were measured, and body mass index (BMI) calculated. After adjusting for age, sex, ethnicity, parental education, height, BMI and time spent in physical activity, each hour per day spent in screen time, watching TV and playing video games was associated with a significant increase in diastolic BP of 0.44 (P ¼ 0.0001), 0.99 (Po0.0001) and 0.64 mm Hg (P ¼ 0.04), respectively. In contrast, each hour per day spent reading was associated with a decrease of 0.91 (P ¼ 0.01) and 0.69 mm Hg (P ¼ 0.02) in systolic and diastolic BP, respectively. Our results indicate that addressing different types of sedentary activities could be a potentially important strategy to reduce the prevalence of elevated BP in children.
