Background: The high prevalence and also multiple consequences of addiction to various online content, including online games and social networks, have become a major challenge. The ability to predict musculoskeletal disorders from this addiction can help reveal in students' health status in the near future. The aim of this study was to determine the prevalence of this addiction and the ability to predict neck pain from this matter in students. Study Design: A cross sectional study. Methods: This study was carried out among 665 students. Data collection was performed through three questionnaires on problematic use of online games, social networking addiction, and Nordic musculoskeletal disorders. Data were compared with Chi-square and independent T-test, and the logistic regression model was then presented at a significant level of 0.05. Finally, the area under the receiver operating characteristic (ROC) curve and Discriminant analysis were conducted to clarify associations. Results: The prevalence of Internet-related content addiction was 32.8%. The results showed that addiction to social networks and online games can increase the risk of neck disorder. Also 0.58 area under ROC curve depicted the ability to predict neck pain from this addiction. Conclusions: In students with internet - related content addiction, neck disorder can be predicted. Given the high prevalence of internet addiction in students, it is essential to take immediate and appropriate interventions to avoid the associated adverse effects such as neck problems.

Abstract: The objective was to analyze the predictive power of indicators of the perception of food and nutritional insecurity comparing beneficiary and non - beneficiary families of the Bolsa Família Program, through a cross - sectional study with 150 families. Demographic, socioeconomic, food insecurity (Brazilian Food Insecurity Scale), nutritional status (Body Mass Index) and household consumption patterns were collected. The correlation between the demographic, socioeconomic, nutritional status and level of food insecurity were tested using the Pearson correlation coefficient; the association with Chi-square and ANOVA tests; and the prevalence ratio and 95% confidence intervals with Poisson Regression model. The predictive power of indicators of food insecurity was evaluated with the ROC curve. Patterns of food consumption, demographic and health characteristics were not significantly correlated with food insecurity. In the analyzes with the ROC curve, among the beneficiary families, the income derived only from the Bolsa Família and the Renda Cidadã Program with the Bolsa Família presented a better predictive power of food insecurity, covering the curve by 70%, followed by the difference between the income from wages and rent and gas (70%). The proportions of the total income of families spent on rent and gas had low predictive power (67%). Income components, mainly rent and gas spending, showed a better performance in the prediction of food insecurity among beneficiaries of Bolsa Família, and could be a complementary quantitative indicator to the Brazilian Scale of Food Insecurity.

Objective: Conventional diagnostic methods are limited in their ability to differentiate destructive thyroiditis from Graves’ disease. We hypothesised that serum diiodotyrosine (DIT) and monoiodotyrosine (MIT) levels could be biomarkers for differentiating destructive thyroiditis from Graves’ disease. Design: Patients with destructive thyroiditis (n = 13) and Graves’ disease (n = 22) were enrolled in this cross-sectional study. Methods: We assayed the serum DIT and MIT levels using liquid chromatography-tandem mass spectrometry. A receiver operating characteristic (ROC) curve analysis was used to determine the sensitivity and specificity of the serum DIT and MIT levels as biomarkers for differentiating destructive thyroiditis from Graves’ disease. Results: The serum DIT and MIT levels were significantly higher in patients with destructive thyroiditis than in those with Graves’ disease. The ROC curve analysis showed that the serum DIT levels (≥ 359.9 pg/mL) differentiated destructive thyroiditis from Graves’ disease, significantly, with 100.0% sensitivity and 95.5% specificity (P < .001). The diagnostic accuracy of the serum MIT levels (≥119.4 pg/mL) was not as high as that of the serum DIT levels (sensitivity, 84.6%; specificity, 77.3%; P = .001). Conclusions: The serum DIT levels may serve as a novel diagnostic biomarker for differentiating destructive thyroiditis from Graves’ disease.

Background: Generalised and central obesity are established risk factors for metabolic syndrome and cardiovascular diseases. Easy assessment of overweight or obesity is the need of the hour from public health perspective. Waist circumference (WC) can be a simple screening tool for identifying overweight individuals since measuring WC is simple, inexpensive, less time consuming, convenient for self-monitoring and needs no complicated calculation as BMI.Methods: A community based cross-sectional study was conducted in January-February 2017 among 338 adults, in a village of Singur Block, West Bengal. Height, weight and WC were measured for each subject. Receiver Operating Characteristic (ROC) curve analysis was used to estimate the cut-off values of WC.Results: The sensitivity and specificity of WC ≥90 centimeters for men for identifying overweight (BMI ≥25) were 78.8% and 75.6% respectively, whereas those of WC ≥80 cm for women were 80.3% and 44% respectively. ROC curve analysis revealed good diagnostic accuracy at 88.5 cm for WC cut-off for men (area under curve (AUC) 0.854, sensitivity 86.5%, specificity 67.6%) and fair accuracy (AUC 0.744, sensitivity 80.3%, specificity 44%) for WC cut-off for 80 cm for women.Conclusions: This study shows, WC can be used for screening of overweight individual infield practice as measuring tape is inexpensive and easy-to-carry compared to a weighing scale. More research may be done on larger sample size to establish an optimal WC cut-off value for Indian population.

Exposure To Secondhand Smoke

Background: Despite the high prevalence of secondhand smoke exposure among Bangladeshi adults, little is known about the knowledge regarding the health effects of exposure to secondhand smoke among the youth aged 15-24 years in Bangladesh. Against this background, the present study was conducted among the youth in Bangladesh to ascertain their levels of knowledge regarding health effects of secondhand smoke and its associated factors.Methods: This was a cross-sectional study of 656 respondents between the age of 15-24 years old selected by multistage cluster sampling. This study was conducted in Dhaka Division, Bangladesh. Data was analyzed using Chi square testing and multivariate logistic regression.Results: The proportion of good, average and poor knowledge scores among respondents were 30.5%, 50.0% and 19.5% respectively. Age and education were significant independent predictors of good knowledge. Furthermore, education and gender were tended as independent predictor of average knowledge. OR for age: 1.12 (95% CI: 1.01 to 1.25); OR for education: 1.27 (95% CI: 1.15 to 1.40).Conclusions: Overall, the results of this study found that less than one-third of the youth had a good level of knowledge on secondhand smoke health effects. The government needs to focus more on less-educated individuals and adolescents if a successful policy is to be implemented.

Objective: This study was conducted to find out the youth perspective about the use of tobacco and its ill effects. The survey was conducted at a private Engineering college of Nagpur, Maharashtra India. Material and Methods: A cross-sectional study with self-administered modified Global youth tobacco survey (GYTS) questionnaire was used for data collection. Eight hundred nine college students of age group between 17 year-24years were included in this study. The questionnaire comprised of information on socio-demographic characteristics and questionnaire was used to gather data on knowledge, attitude and practices of participants about tobacco use. Data analysis was performed by using chi-square test and Statistical significance was measured at a level of 0.05. Result: Out of 806 total participants, 136 (16.8) were current tobacco consumers, significantly high prevalence of tobacco use was observed among boys 106 (13.1) than girls 30 (3.7). Moreover, a higher number of boys 106 (13.1) started smoking at young adolescent age (13- 20 years) than girls30 (3.7). Conclusion: The findings in the study suggest that tobacco use is still an important risk behavior amongst students. Tobacco use was comparatively higher amongst boys though its use is not restricted to them only. There is a need to plan to gather nationwide baseline data on the use of tobacco by young adolescents and the factors associated with initiation of tobacco habit.KeywordsGlobal youth tobacco survey (GYTS); Tobacco prevalence; Tobacco use among youth.

Background. Migraine is the most common neurological disorder associated with a wide range of psychiatric comorbidities. It is therefore regarded as a major global health problem due to its high prevalence. Here we investigated the factors associated with migraine among an Iranian population. Methods. This investigation included a cross-sectional study consisting of 270 migraine patients. Initially, a questionnaire was designed based on demographic information and headache characteristics. SPSS analyzed the collected data, and chi-square and logistic regression were used to evaluate the clinical data. Results. Our findings revealed that many migraine patients are experiencing multiple trigger factors, with stressful life events being the most common in both genders and migraine subtypes. The incidence of migraine was higher in women than in men. Among the trigger factors leading to the intensification of migraine attacks, stress, sleep changes, and bright lights were the most common and important causes of headache, followed by tiredness and weather change disturbance. Conclusions. Considering the contradictory reports on the effect of trigger factors on migraine, further studies are needed to be performed. Due to the significance of the socio-economic impact of migraine on patient’s quality of life, strategies for managing these factors should be effectively implemented to improve the community’s health.

Musculoskeletal disorders (MSDs) are the most common health complaints in the working population and the advancement in technology is a big contributor. Many offices and work spaces have been revolutionised with technological advances, most notably through computer usage, which has become an integral part of life. Intensive use of computers has shown to result in MSDs. The aim of this study was to examine the occurrence of MSDs in a library setting at a University of Technology with the objectives of: determining the prevalence of MSDs in the library staff, to describe the workstations of the staff, and to describe any associations between the workstations and MSDs. This was a cross sectional study at two libraries at a University of Technology with a sample of 59 library staff. The study involved a two part process in which an observational assessment of the library staff was conducted by the researcher with each staff member individually, followed by a questionnaire completed by each participant. The observational checklist was used as a means to assess the ergonomic environment of the library staff. The questionnaire included demographic information, pain-related questions, psychosocial questions, and perception-based questions regarding the participants’ work environment. Statistical analysis was performed using SPSS (version 24), including descriptive and inferential statistics. Statistics included frequencies, measures of central tendency, and variance and measures of association for example chi-square, Cronbach’s alpha and correlation statistics. The study indicated a prevalence of 96% for some kind of MSD. One out of every two participants had reported that the MSDs or pain interferes with their work. Certain risk factors were evident from the study, namely: inappropriate desk height, reaching for items in the work place, noise, inappropriate chairs and inadequate leg room. The most commonly reported MSDs related to neck (55.9%), shoulders/upper arm (55.9%), head (49.2%), and knees/legs (49.2%). The significant associations that were present included head and neck MSDs with noise and upper arm positioning in worker posture and hand pain. Significant rates of MSDs were reported by the participants with half of them reporting that pain caused interference with their work and only a small portion of participants seeking treatment for these conditions. It would be beneficial for the library staff to become more aware of MSDs and their ergonomic environments both at work and privately and to take corrective action to better equip themselves to mitigate MSDs and seek treatment when needed.
