The association between obesity and problematic smartphone use among school-age children and adolescents: a cross-sectional study in Shanghai.

ABSTRACT:

Background

The study aimed to investigate the association between content-based problematic smartphone use and obesity in school-age children and adolescents, including variations in the association by educational stage and sex.

Methods

Two-stage non-probability sampling was used to recruit 8419 participants from nineteen primary schools, five middle schools, and thirteen high schools in Shanghai in December 2017. Obesity was identified by body mass index (BMI), which was obtained from the school physical examination record, while problematic smartphone use was measured by the Revised Problematic Smartphone Use Classification Scale as the independent variable.

Results

The rates of obesity varied with educational stages, while problematic smartphone use increased with educational stages. Male students reported higher obesity rates (37.1%vs19.4%, P < 0.001) and greater problematic smartphone use scores (25.65 ± 10.37 vs 22.88 ± 8.94, P < 0.001) than female students. Problematic smartphone use for entertainment (smartphone users addicted to entertainment games, music, videos, novels and other applications) was positively associated to obesity status for primary school [odds ratio (OR), 1.030; 95% confidence interval (95% CI), 1.005-1.057] and high school students (OR, 1.031; 95% CI, 1.004-1.059). For female students, problematic smartphone use for entertainment was positively associated with obesity status (OR, 1.046; 95% CI, 1.018-1.075).

Conclusions

Problematic smartphone use may be associated with obesity in children and adolescents. The association differed based on the educational stage and sex, and the difference possessed dimensional specificity.

Project description:IntroductionChildren and adolescents with overweight and obesity have an impaired health-related quality of life (HRQoL). However, it is unclear which of these children are most affected in their physical, psychological, and social functioning. Therefore, this study aimed to evaluate HRQoL in treatment-seeking children and adolescents with overweight, obesity, and severe obesity.MethodsA cross-sectional study was performed at the Centre for Overweight Adolescent and Children's Healthcare (COACH). Children and adolescents (8-17 years) with overweight, obesity, and severe obesity were included. The primary outcome was the self-reported HRQoL measured with the KIDSCREEN-27.ResultsA total of 419 participants with overweight (N = 121), obesity (N = 182), and severe obesity (N = 116) were included. One-way ANOVA analysis showed that children and adolescents with severe obesity reported significantly lower physical well-being (41.25 ± 13.14) compared to those with overweight (47.91 ± 12.53; p < 0.001) and obesity (46.74 ± 11.93; p < 0.001). Furthermore, impaired psychological well-being was found in the group with severe obesity (45.14 ± 13.27) in comparison to the group with overweight (50.90 ± 9.48; p < 0.001) and obesity (49.71 ± 10.95; p = 0.002). Multivariable linear regression analysis, while correcting for age, sex, cardio metabolic health risk, and ethnicity, revealed similar results. Additionally, children and adolescents with severe obesity scored lower regarding autonomy and parent relation than those with overweight (B = 3.95; p = 0.009). In almost all groups and dimensions of the KIDSCREEN-27, caregivers scored lower compared to the children and adolescents themselves. Furthermore, a low child-caregiver agreement seemed to exist, especially in the children and adolescents with overweight.ConclusionThe HRQoL of treatment-seeking children and adolescents with overweight and obesity was most affected in children and adolescents with the most severe grade of obesity. Following these findings, lifestyle intervention programs targeting childhood obesity should be aware of this even more vulnerable group so that treatments can be tailored according to their needs.

Project description:BackgroundThe Gulf Cooperation Council (GCC) countries have among the highest prevalence of adult obesity and type 2 diabetes in the world. This study aimed to estimate the recent prevalence of obesity among school-age children and adolescents in the GCC States.MethodsThe literature search for obesity prevalence data was carried out in July 2017 in Google Scholar, Physical education index, Medline, SCOPUS, WHO, 2007-2017, and updated in November 2018.In addition, 22 experts from the GCC were contacted to check the search results, and to suggest studies or grey literature which had been missed. Eligible studies were assessed for quality by using the Joanna Briggs Institute (JBI) tool for prevalence studies. Conduct of the systematic review followed the Assessment of Multiple Systematic Reviews Tool (AMSTAR) guidance. A narrative synthesis was conducted.ResultsOut of 392 studies identified, 41 full-text reports were screened for eligibility; 11 of which were eligible and so were included, from 3 of the 6 GCC countries (United Arab Emirates, Kuwait, Saudi Arabia). Surveillance seems good in Kuwait in compared to other countries, with one recent national survey of prevalence. Quality of the eligible studies was generally low-moderate according to the JNBI tool: representative samples were rare; participation rates low; power calculations were mentioned by only 3/11 studies and confidence intervals around prevalence estimates provided by only 3/11 eligible studies; none of the studies acknowledged that prevalence estimates were conservative (being based on BMI-for-age). There was generally a very high prevalence of obesity (at least one quarter-one third of study or survey participants obese according to BMI-for-age), prevalence increased with age, and was consistently higher in boys than girls.ConclusionsThe prevalence of obesity among school-age children and adolescents appears to have reached alarming levels in the GCC, but there are a number of major gaps and limitations in obesity surveillance in the GCC states. More national surveys of child and adolescent obesity prevalence are required for the GCC states.Trial registrationPROSPERO registration number CRD42017073692.
