Prevalence of physical activity and sedentary-related behaviors among adolescents: data from the Qatar National School Survey

OBJECTIVES

To investigate the prevalence of physical activity (PA) and sedentary behaviors among adolescents in Qatar by selected demographic characteristics.

STUDY DESIGN

Cross-sectional study.

METHODS

A total of 5862 students (2938 boys and 2924 girls) in the age group 12-17 years were included in the analyses. PA and sedentary-related measures were obtained from the self-reported survey questions.

RESULTS

Only 35.4% of students were performing 60 min of PA ≥3 days/week. The proportion of students with >2 hr screentime ranged from 43% to 57% (weekdays) and 50% to 62.5% (weekends). Girls had less odds of being physically active than the boys (odds ratio [OR] = 0.61, P < 0.001). Qatari students were less likely to be physically active than non-Qataris (OR = 0.79, P < 0.001). Age was inversely correlated with PA ([r = -0.113, P < 0.001 for participation with sports team] and [r = -0.139, P < 0.001 for school physical education classes]). Participation in sports teams positively correlated with 60 min of PA number of days in a week (r = 0.317, P < 0.001).

CONCLUSIONS

The study describes insufficient PA among youth as a public health issue of concern in the State of Qatar that requires multipronged health promotion initiatives.

The prevalence and characteristics of overweight and obesity among students in Qatar

OBJECTIVES

To estimate the prevalence of overweight and obesity using World Health Organisation (WHO) cut-offs for the body mass index (BMI) among students of the general population living in Qatar in the period 2015-2016.

STUDY DESIGN

Cross-sectional study.

METHODS

The study includes 164,963 students aged 5-19 years. The body weight and height were measured to calculate the BMI. The WHO standard cut-offs were used to categorise the BMI into severe thinness (BMI z-score <-3), thinness (BMI z-score ≥-3 to <-2), normal (BMI z-score ≥-2 to <1), overweight (BMI z-score ≥+1 to <+2) and obese (BMI z-score >+2).

RESULTS

Overweight and obesity prevalence was 44.8% and 40.4% among males and females and 45.6% and 40.9% among Qatari and non-Qatari students, respectively. Odds of obesity and overweight status were significantly higher among 10-14 and 15-19 age groups than 5-9 years age group (P < 0.001). By sex, males had 1.48 times higher odds of having obesity than females (P < 0.001), and Qatari nationals had 1.4 times higher odds of obesity than non-Qataris (P < 0.001). Although non-Qatari males also had higher odds of being overweight than females (odds ratio [OR] = 1.05, P = 0.0006), the opposite was seen among Qatari students (OR = 0.95, P = 0.01).

CONCLUSION

The result of this survey provides evidence of a high prevalence of overweight and obese students living in Qatar. Therefore, preventive strategies are essential in this population to lower the incidence of being overweight and obesity.
