Purpose. To analyse the correlation of myopia with physical exercise and sleep habits to explore the possible risk or protective factors of juvenile myopia. Methods. This study was a retrospective cross-sectional study. A total of 1831 students aged 11–18 years from five schools in Qingpu completed questionnaires from 2018 to 2019; the students were divided into the nonmyopia group and the myopia group, with students in the myopia group having myopia in at least one eye. Based on the chi-square test, the variables with statistical significance were selected for the logistic regression analysis. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were determined. Results. Myopia was positively associated with older age (OR = 2.216, 95% CI: 1.720–2.855), having a parent with myopia (father: OR = 2.463, 95% CI: 1.900–3.193; mother: OR = 2.853, 95% CI: 2.232–3.646), and a late bedtime during holidays (before 10 pm: p = 0.002; 10 pm-11 pm: OR = 1.516, 95% CI: 1.095–2.100; 11 pm-12 am: OR = 1.966, 95% CI: 1.383–2.795), but negatively correlated with male gender (OR = 0.693, 95% CI: 0.549–0.876), a late daily wake time (OR = 0.782, 95% CI: 0.621–0.985), and having more days per week of outdoor activities during the semester (OR = 0.764, 95% CI: 0.597–0.978). After adjustment for demographic characteristics, myopia was positively associated with a late bedtime during holidays (before 10 pm: p = 0.003; 10 pm-11 pm: OR = 1.570, 95% CI: 1.076–2.289; 11 pm-12 am: OR = 2.173, 95% CI: 1.451–3.253; after 12 am: OR = 1.786, 95% CI: 1.093–2.919), but negatively correlated with a late daily wake time during the semester (OR = 0.761, 95% CI: 0.581–0.997). Conclusion. The association of outdoor exercise with myopia among Chinese suburban adolescents does not seem to be as strong as that of sleep habits. Future research could seek to provide consistent evidence for a potential association between myopia and sleep habits.

The aim of this study was to evaluate knowledge on pre-hospital emergency management of tooth avulsion among Croatian kindergarten teachers. A cross-sectional study was conducted among 33 educators in kindergarten (average 43.9±9.7 years). The questionnaire contained 10 close-ended questions with two or eleven possible answers. Statistical significance was determined using chi-square test. Majority of participants had no experience with tooth injury among children in kindergarten. Questions about the familiarity with the terms of a knocked-out tooth and tooth replantation and whether the knocked-out tooth should be replanted were confirmatively answered by 90.9%, 57.6% and 63.6% of participants, respectively. Only 9.1% of participants provided the correct answer that replantation should be done within 30 minutes. 78.8% of participants would choose correct medium for cleaning if avulsed tooth got dirty. Tooth would be transported in appropriate medium by 48.5% of participants. Correct answers on both the transport medium and the cleaning of knocked-out tooth were provided by 45.5% participants. 57.6% participants would seek help for replantation by visiting the nearest dentist. None of the participants had ever received any kind of information on management of a knocked-out tooth. The kindergarten teachers have a lack of knowledge for immediate response to tooth avulsion. Every kindergarten teacher should be well informed what should be done if some type of dental injury happens. The official communication between dental professionals and kindergarten teachers should be improved at local and regional level.

Background: Self-medication is defined as the use of medicines to treat self-recognized or self-diagnosed conditions or symptoms, instead of seeking advice from professionals. Aim: Our study was aimed to assess knowledge, attitude and practice of self-medication among undergraduates in different colleges of Kathmandu valley. Methods: Descriptive cross-sectional study was carried out among undergraduates of Kathmandu valley. A semi-structured questionnaire was distributed to students in 4 different colleges. Chi-square test was used to determine statistical significance. Likert’s scale was used to measure attitude. Results: 240 students participated in this study. Totally, (92.9%) students had known and taken medicine without doctor’s prescription. More than half of the participants (56.6%) had good knowledge on self-medication and nearly three quarter (74.7%) of the respondents had a positive attitude regarding self-medication. Fever, cough/cold and aches/pain were the most common symptoms for self-medication, thus making antipyretics and analgesics the most popular self-medication drugs. Pharmacists and family were the major source of information regarding self-medication. Conclusion: Based on the findings, the prevalence of self-medication was high (94.9%). Majority respondents had good knowledge of the advantages and disadvantages of self-medication but still practiced it.

The purpose of this study was to evaluate the knowledge regarding tooth avulsion and dental first aid response among Croatian students of the Faculty of Education. A cross-sectional study was conducted among students. Participants (N = 235) were female with an average age of 21.9 ± 2.7 years. The questionnaire contained 10 close-ended questions with two to eleven possible answers. Every participant chose one correct answer. Statistical significance was determined using a Chi-square test. Majority of participants had never received any kind of information on management of a knocked-out tooth. Questions in the nature of tooth injuries, a knocked-out tooth, tooth replantation and whether the knocked-out tooth should be placed back were answered confirmatively by 40.43%, 83.40%, 57.02% and 62.55% of participants, respectively. The questionnaire showed that 18.78% of participants were aware that replantation should be performed within 30 min. The appropriate cleaning and transport medium was chosen by 40.85% and 35.31% of participants, respectively. A nearby dentist would be visited by 66.38% of students. Only 8.08% of participants provided a correct answer to all of the knowledge-based questions. The “I do not know” answer was chosen by 18.30% of participants whenever it was offered. This indicates that the majority (89.78%) were not aware of the fact that the procedure they chose would be inappropriate. The current study confirmed that future primary school teachers have a lack of knowledge for immediate response to tooth avulsion, leaving small chances for a successful prognosis of tooth replantation.

Abstract The aim of this study was to verify sleep hours and associated factors among Brazilian and Spanish students. A cross-sectional study with students aged 11 to 16 years-old was carried out in Paranavaí, Brasil (n = 264) and Cáceres, Spain (n = 233) between 2013 and 2015. Sleeping hours were verified regarding time in minutes, sleep in weekdays, weekends and after lunch/Siesta. All data were checked for normality by the Kolmogorov-Smirnov test. Mann-Whitney U test, Chi-square test (X2) and Odds Ratio estimates were used (p < 0.05). High prevalence in both groups of sleeping 8 hours or more a night at the weekend. The prevalence of sleeping on weekdays, > 8 hours, 6 to 8 hours and < 6 hours among Spanish and Brazilian students, respectively. Nearly a quarter of each group responded that makes the siesta. Spanish students had 3 times higher chance to sleep < 8 hours a night in weekdays, among students from 14 to 16 years old and among the underactive. At the weekends the chance of sleeping < 8 hours is 2 times greater among the Spanish students. Simple guidelines could help so that sleep habits do not affect school development, such as practicing physical activity regularly, sleeping at least 8 hours a night, avoid excessive access to technology at night.

This survey was taken up to analyze the association between food habits and sleep with obesity. The survey involved 200 healthy participants of both genders.  A cross sectional study was planned among the saveetha university students. Generalised questionnaires which assess the food habits of the participants was designed to find how it relates with obesity and PITTSBURGH sleep quality index (PSQI) was used to assess sleep habits of the subject during the past one month. The responses of the questions were tabulated and the correlation of food habits and sleep with the tendency of obesity and gender-related analysis was done using SPSS software version 22 and the statistical test used was chi-square test and the significance value was fixed at p < 0.05. The results revealed that about 49% of people have trouble sleeping. 51% of people less than once a week face trouble. 53 % of people use the bathroom in the middle of sleep. 56% of people drink soft drinks two times per day. There were also significant changes among genders in the intake of junk food intake, appetite and sleep rating. Thus the study concluded that food habits with the intake of junk food and sleep deprivation with gender correlation predispose to obesity.

Introduction: Smile line is a major factor considered in esthetic treatment planning.Objective: To assess the position of the smile line both in natural and forced position in relation to age and gender in Nepali population sample.Materials & Method: A cross sectional study was done in 220 adults. DSLR camera was used to take photograph of the participants. Two different photographs were taken of each participant in natural and forced smile position in standardized format. The smile lines were determined and classified according to Liebart et al. Data analysis was done by SPSS 20.0 software. Chi square test was performed to analyze statistical significance between the gender and age groupsResult: Maximum individuals had low type of natural smile (59.1%) and average type of forced smile (40.0%). Very few individuals had very high type of natural smile (1.4%) and very high type of forced smile (15.9%). Among all, 41% had visibility of the periodontium during normal smile while on forced smile 79.1% had visibility of the periodontium.Conclusion: Females have significantly more periodontal visibility when compared to males during forced smile in Nepali population sample. This concept of smile line should be utilized for treatment planning to achieve desirable facial esthetics in many fields of dentistry including Orthodontics, Prosthodontics, Periodontics, Restorative Dentistry.

Objective: To determine the immunophenotyping of a population of blood donors, intended to build a database for transfusion medicine. 2) To make available to patients with chronic diseases that are systematically dependent on blood transfusions as compatible as possible in ABH, Rh (DCcEe) and Kell 1 antigen systems. Method: A cross-sectional study was carried out on 11,664 blood donors for the ABH system typing and of these, 1255 blood donors were selected randomly for the determination of blood group antigens of the Rh system and Kell antigen. Blood centrifugation methods, centrifuge hemolysis tube test and indirect Coombs test were used for blood typing. The results obtained were compared by the Chi-square test. A level of statistical significance of p ≤ 0.05 was considered. Results: Antigenic frequencies for the ABH system found: the frequency found for the blood group O 48.8%, the frequency found for the blood group A 35.4%; the frequency found for the blood group B 10.6% and the frequency found for the blood group AB 3.2%. In the Rh-Hr system the most frequent antigens found: e 94.5%, D 88.9%; c 80.6; C 56.4%; E 26.3%. For the Kell antigen, the frequency found was 6.7%. The most frequent phenotypes found were DCcee 23.3%; ddccee 18.1%, DCCee 16.7%; Dccee 11.0%; DCcEe 10.2% and DccEe 8.8%. The lowest frequency was found: DCcEE 0.64% and ddCcEe 0.08% Conclusion: The antigenic and phenotypic frequencies found show the great importance and necessity of the immunophenotyping of these antigens of blood groups in order to transfuse them, making them as compatible as possible, thus reducing the risk of alloimmunization. Due to the great miscegenation of our population, we find different frequencies in each region, making initiatives in this regard more relevant. Disclosures No relevant conflicts of interest to declare.
