Review Meta AnalysisEffect of screen time intervention on obesity among children and adolescent: A meta-analysis of randomized controlled studies.
Several studies have investigated the effect of screen time interventions on obesity in children and adolescents, but the existing results were controversial. This study aimed to analyze the effect of screen time intervention on obesity in children and adolescents. PubMed, Cochrane, Web of Science, Embase databases were searched through December 2020 to identify publications meeting a priori inclusion criteria and references in the published articles were also reviewed. ⋯ The results showed that interventions targeting screen time are effective in reducing total screen time (MD: -6.90 h/week, 95% CI: [-9.19 to -4.60], p < 0.001) and television time (MD: -6.17 h/week, 95% CI: [-10.70 to -1.65], p < 0.001) in children and adolescents. However, there was no significant difference between the intervention and control groups in body mass index and body mass index-z score. In conclusion, there is no evidence that screen time interventions alone can decrease obesity risk in children and adolescents, though they can effectively reduce screen time.

ReviewElectronic health literacy and health-related outcomes among older adults: A systematic review.
This review aims to identify, appraise, and synthesize research evidence of the association between electronic health (eHealth) literacy and health outcomes in older adults. English-written articles that presented the relationships between eHealth literacy and health-related outcomes in older adults were identified by searching five scientific databases (Web of Science, PubMed, Cochrane Library, APA PsycInfo, and EMBASE) hand-searching reference lists. Searches yielded 2993 studies after duplicates were removed, of which 24 publications were included in the final review. eHealth literacy was relatively low in older adults, and the eHealth Literacy Scale, developed by Norman and Skinner in 2006, was the most frequently used instrument in the included studies (21/24, 87.5%). ⋯ Most included studies were assessed as moderate quality. Overall, higher eHealth literacy is associated with more positive health behaviors and better health knowledge and attitude in older adults, however, the associations with some physical and psychosocial outcomes are less consistent. Clarifying the pathways of the relationships between eHealth literacy and some health-related outcomes is needed for further exploring their underlying mechanisms.

Randomized Controlled TrialPostal reminder with reduced burden of clinic information seeking for equitable participation in general health check-ups: A randomized controlled trial.
High participation rate and low inequality in participation are key to the program success of general health check-ups in Japan. This study examined the effectiveness of a postal reminder including nearest clinic information, compared to the standard postal reminder including details of all local clinics, on participation rate and income-based participation rate in general health checks. This was a single-blind, two-arm, prospective, randomized controlled study conducted at the Fukuoka Branch of Japan Health Insurance Association. ⋯ The intervention effect was estimated to decrease as the income category increased (P for interaction = 0.037). Tailored postal reminders with information on the nearest clinic were able to improve the overall participation rate and reduce income-based inequality in participation for general health check-ups in Japan. Trial registration: UMIN-CTR, UMIN000042509, Registered 26 November 2020 - Retrospectively registered.

Latent profile analysis to identify subgroups of Chinese sexual minority adolescents at risk of suicidality.
This study aimed to identify latent class profiles of sexual minority adolescents (Men Sexually attracted to Men, Women Sexually attracted to Women, and Bisexual) with elevated suicidal ideation. ⋯ Sexual minority adolescents with mood problems have the highest risk of suicidal ideation, followed by adolescents frequently being bullied at school. Interventions aimed at reducing suicide risk among sexual minority adolescents may benefit from attending to such profile factors identified in this study to develop targeted clinical care.

Trends in material and non-material inequalities in adolescent health and health behaviours: A 12-year study in 23 European countries.
Information on trends in adolescent health inequalities is scarce but the available evidence suggests that inequalities are increasing. Prior studies describe associations between material resources of socioeconomic status (SES) and health, while information on non-material SES resources and inequalities in health behaviours is lacking. To improve current understandings of evolutions in adolescent health inequalities, we examined how material and non-material SES resources were associated with changes in selected health outcomes (life satisfaction, physical and psychological symptoms) and health behaviours (physical activity, screen time, breakfast, fruit, vegetables, sweets and soft drinks consumption and alcohol and tobacco use) over a 12-year period. ⋯ Non-material inequalities increased in all health behaviours (except for sweets consumption) between highest and lowest occupational social class groups: physical activity (0.16 to 0.24 h/day difference; p = 0.0071), screen time (-0.41 to -0.58 h/day difference; p < 0.001), breakfast (0.21 to 0.51 day/week difference; p < 0.001), fruit (OR 1.23 to 1.48 higher odds; p < 0.001), vegetables (OR 1.39 to 1.74 higher odds; p < 0.001) and soft drinks consumption (OR 0.59 to 0.43 lower odds; p < 0.001) and alcohol (OR 0.99 to 0.85 lower odds; p = 0.0420) and tobacco use (OR 0.71 to 0.59 lower odds; p = 0.0183). In summary, non-material inequalities in most health behaviours increased, whereas material inequalities in adolescent health and health behaviours remain stable or decreased. Policies and interventions may consider non-material SES components as these can help in reducing future health inequalities.
