Purpose: The purpose of this survey was to explore the prevalence of reduced visual acuity and its associated factors among school students in Shenyang in 2016. Methods: This was a cross-sectional study using data from the Ministry of Education’ Student Physical Fitness (MESPF) monitoring in 2016. A total of 13,642 students aged 9–18 years were surveyed in Shenyang. The unaided distance visual acuity was measured, and questionnaire on lifestyle behaviors that may affect visual acuity was investigated among students. The prevalence of reduced visual acuity and its associated factors were analyzed. Results: The average prevalence of reduced visual acuity among students aged 9–18 years was 65.8%, and severe reduced visual acuity was main (42.9%), and there were statistical effect of age, gender, and region on the prevalence of reduced visual acuity. Binary and multi variable logistic regression results revealed that students sleeping <8 h, homework hours ⩾1 h, and parental myopia had an increased risk of reduced visual acuity. Conclusions: Sleep time <8 h and homework time ⩾1 h may be associated with reduced visual acuity among students in Shenyang. Therefore, it is benefit for student to get enough sleep and decreasing studying time in order to prevent and reduce poor vision.

Objective: The purpose of this research was to investigate the prevalence of lifestyle behaviors and suicide-related behaviors and the association between them using a nationally representative sample of adolescents from the USA.Methods: 13,677 high school students aged 14-18 years were included in this cross-sectional study. The research data were retrieved from the Youth Risk Behavior Surveillance System Survey in 2019. All data on age, sex, grade, race, physical activity, television time, fruit intake, and suicide-related behavior were self-reported by students. Logistic regression models were adopted to examine the association between lifestyle behaviors and the suicide-related behaviors.Results: Students who played video/computer games for ≥2 h had higher risk of suicide attempt (OR = 1.55, 95%CI: 1.30-1.85). Daily sleep duration of ≤8 h was positively associated with considering a suicide attempt (OR = 1.99, 95%CI: 1.62-2.43). In addition, participants who did not engage in any sport team were more likely to report considering a suicide attempt (OR = 1.50, 95%CI: 1.24-1.81).Conclusion: This research suggests that some lifestyle behaviors (e.g., time for video or computer use, sleep duration, sports team participation, regular breakfast intake, and substance use) are associated with increased risk of suicidal behavior and ideation in high school students. To identify the specific effect of multiple lifestyle factors in influencing the risk of suicide-related behaviors in high school students, longitudinal studies are warranted in future.

Adolescents involved in bullying can be at risk of developing behavioural problems, physical health problems and suicidal ideation. In view of this, a quantitative research design using a cross-sectional study was conducted to determine the prevalence of bullying and associated individual, peer, family and school factors. The study involved 4469 Malaysian public-school students who made up the response rate of 89.4%. The students were selected using a randomized multilevel sampling method. The study found that 79.1% of student respondents were involved in bullying as perpetrators (14.4%), victims (16.3%), or bully–victims (48.4%). In a multivariate analysis, the individual domain showed a significant association between students’ bullying involvement and age (OR = 1.38; 95% CI 1.12–1.70), gender (OR = 1.73; 95% CI 1.47–0.91), ethnicity (OR = 0.66; 95% CI 0.47–0.91), duration of time spent on social media during the weekends (OR = 1.43; 95% CI 1.09–1.87) and psychological distress level (OR = 2.55; 95% CI 1.94–3.34). In the peer domain, the significantly associated factors were the number of peers (OR = 0.69; 95% CI 0.56–0.86) and frequency of quarrels or fights with peers (OR = 2.12; 95% CI 1.24–3.26). Among the items in the school domain, the significantly associated factors were students being mischievous in classrooms (OR = 1.52; 95% CI 1.06–2.06), student’s affection towards their teachers (OR = 1.53; 95% CI 1.06–2.20), frequency of appraisal from teachers (OR = 1.49; 95% CI 1.16–1.94), frequency of friends being helpful in classrooms (OR = 1.92; 95% CI 1.09–3.38) and frequency of deliberately skipping class (OR = 2.91; 95% CI 2.90–1.72). As a conclusion, the study revealed high levels and widespread bullying involvement among students in Malaysia. As such, timely bullying preventions and interventions are essential, especially in terms of enhancing their mental health capacity, which substantially influences the reduction in the prevalence rates of bullying involvement among students in Malaysia.

Abstract Background Uncorrected refractive errors contribute enormously to the burden of avoidable visual impairment worldwide. There is a huge disparity in different parts of the globe in context to spectacle coverage for distance vision. This study was undertaken with objectives of determining prevalence of spectacle coverage, unmet needs and associated factors among adults in a rural community of north India. Methods A community-based cross-sectional study was carried out within selected clusters of Jhajjar district of Haryana. All participants aged > 15 years underwent visual acuity assessment by LogMAR “E” screening chart. Participants with presenting visual acuity < 6/12 in any eye and all current spectacle users underwent detailed ophthalmic examination and refraction. Additional details about spectacles, barriers for their use and willingness to pay for them were collected. Participants with met and unmet need for spectacle use at visual acuity > 6/12 was computed. These are reported as proportions with 95% confidence intervals. Associated factors with unmet need were determined using bivariable and multivariable logistic regression analysis. Results A total of 6910 participants were examined. The current spectacle use was 7.5% (95% Confidence Interval CI: 6.5, 8.7). The spectacle coverage was found in 33.3% (95% CI: 30.0, 36.7) participants among those in need. The unmet need was found in 10.8% of participants (95% CI: 10.1, 11.6). On multivariable analysis, odds of unmet need was associated with age, gender, level of education and marriage status. The most common barrier for refractive correction was lack of perceived need for refraction and its correction. Conclusion There is substantial unmet need for distance vision spectacles in this population. It is imperative that multi-component intervention be implemented to improve spectacle coverage in this rural north Indian setting.

Purpose: To determine the prevalence of asthenopia and its associated factors in a sample of university students in Iran. Methods: In this cross-sectional study, participants were selected using multistage cluster sampling. Presence of at least one of the 10 symptoms—foreign body sensation, diplopia, blurred vision, eye swelling, dry eye, eye pain, difficulty in sustaining visual operations, decreased visual acuity, tearing, and photophobia—was considered as asthenopia. Ocular examinations, including uncorrected/corrected visual acuity measurement, objective/subjective refraction, cover test, amplitude of accommodation (AA), and near point of convergence (NPC) were performed. Results: Of the 1,462 students (mean age: 22.8 ± 3.1 years), 73% were women. The age- and gender standardized prevalence was 70.9% (95% confidence interval [CI]: 68.3–73.5), 39.8% (95% CI: 36.4–43.1), and 19.7% (95% CI: 16.0–23.3) based on the presence of at least one, two, and three symptoms, respectively. The prevalence was significantly higher in females (P = 0.048), hyperopic students (P < 0.001), and astigmatic participants (P < 0.001). The mean AA and NPC were 9.7 ± 2.6 D and 10.2 ± 4.2 D (P = 0.008) and 7.0 ± 2.1 cm and 7.7 ± 3.9 cm (P < 0.001) in participants with and without asthenopia, respectively. Multiple regression model revealed age (28–29 years), astigmatism, and NPC as independent associated factors (odds ratios: 3.51, 1.61, and 0.91, respectively). Conclusion: This study shows relatively high prevalence of asthenopia in university students. Demographic factors and visual system disorders are important risk factors and timely correction of conditions may lead to decreased asthenopia.

Abstract Background Hypertension (HTN) could have its origin in childhood and remain undetected unless a special screening is done during this period. We conducted this study to determine the screened HTN prevalence in adolescents and its associated factors, in order to increase the awareness on this subject and lead the state to make preventive strategies. Methods A cross-sectional study was carried among secondary school students in Sousse, Tunisia, during 2017-2018 school year. Blood pressure and anthropometric indices were measured. A structured questionnaire was used to collect information about socio demographic characteristics, lifestyle, addictive behavior and mental health status. Results A total of 1399 adolescents participated in the study. The prevalence of screened HTN was 15.6% (95% CI[13.8% -17.5%]). It was significantly higher in boys (23.1%) than in girls (10.7%; p ≤ 10-3). After binary logistic regression, positively associated factors to screened HTN in total population were: obesity (aOR=3.69; p ≤ 10-3), and overweight (aOR=1.7; p ≤ 10-3). Female gender (aOR=0.4; p ≤ 10-3), School failure (aOR=0.64; p = 0.014) and depression (aOR=0.67;p=0.017) were negatively associated to screened HTN. Conclusions Our study showed an alarming prevalence of high blood pressure among secondary school adolescents in our Low Middle Income Country and that it was mainly associated with weight excess. This emphasizes the emergent need of a comprehensive strategy for the prevention and control of hypertension and NCD risk factors among youth. Key messages Hypertension is an alarming emerging problem among youth in LMIC The emergent need of an effective strategy to prevent NCD risk factors in LMIC Keywords Hypertension Prevalence - Adolescent lifestyle- behavior, addictive - mental health
