Prevalence and risk factors of Internet addiction in high school students.

AIM: In this study, the prevalence and risk factors of Internet addiction in high school students was investigated. MATERIAL AND METHOD: This cross-sectional study was performed in the Mersin Province in 2012. The study sample consisted of students attending high school in the central district of Mersin. The data were summarized by descriptive statistics and compared by a binary logistic regression. RESULTS: Our study population included 1156 students, among whom 609 (52.7%) were male. The mean age of the students was 16.1 ± 0.9 years. Seventy-nine percent of the students had a computer at home, and 64.0% had a home Internet connection. In this study, 175 (15.1%) students were defined as Internet addicts. Whereas the addiction rate was 9.3% in girls, it was 20.4% in boys (P < 0.001). In this study, Internet addiction was found to have an independent relationship with gender, grade level, having a hobby, duration of daily computer use, depression and negative self-perception. CONCLUSION: According to our study results, the prevalence of Internet addiction was high among high school students. We recommend preventing Internet addiction among adolescents by building a healthy living environment around them, controlling the computer and Internet use, promoting book reading and providing treatment to those with a psychological problem.

A five year retrospective surveillance; monitoring and evaluation for the regional tuberculosis control programme in Mersin, Turkey, 2004-2008.

AIM: The aim of this study is to identify and evaluate problems in regional tuberculosis control studies, using an international tuberculosis indicator. METHODS: In this retrospective cohort study, the records of a total of 1,776 patients diagnosed with tuberculosis, followed up and treated from 2004-2008 in Mersin were evaluated. Indicators recommended by the World Health Organization were used as assessment criteria. Descriptive statistics were used to summarize data. The Mantel-Haenszel test was used for calculation of the risk between urban/rural, and between male/ female which were in different age groups. RESULTS: During the five year period, new case notification rates were reduced and tuberculosis risk shifted to advanced age groups in our region. Tuberculosis development risk increased two-fold among males (p < 0.001). One-fifth of the tuberculosis cases had been diagnosed without sputum smears. Sputum microscopy was not done at the end of the initial phase in one-fifth of patients. During the five-year follow-up period, tuberculosis treatment success rate increased from 83% to 91% and cure rate increased from 49% to 67%. The death rate, treatment failure rate, default rate, and transmission rate decreased, and the directly observed treatment implementation increased. CONCLUSION: Improvements were seen in diagnosis and treatment indicators beginning from 2006; the year when the directly supervised treatment application started. However, use of sputum smear microscopy is inadequate for the diagnosis and treatment of tuberculosis. Tuberculosis control studies should be monitored and evaluated using a tuberculosis indicator.

Knowledge of emergency contraception among women aged 15-49 years in Mersin, Turkey.

OBJECTIVE: To determine the knowledge of, use of and willingness to use emergency contraception (EC) among women in Turkey. STUDY DESIGN: This cross-sectional study was conducted among 1,298 women at 12 primary health care centers in Mersin. Chi-square, Student's t test, Mann-Whitney U and binary logistic regression tests were performed for statistical analysis. RESULTS: Overall, 18.1% of the women had heard of EC, and of those, 73.6% correctly identified the time limit for the method's use. Among women who had heard about EC, the most commonly cited source of information was health care centers. Knowledge of EC was independently associated with younger women, higher education, having received counseling about family planning, having had an unintended pregnancy, and being employed. Of women who had been sexually active, 4.4% reported having used EC. CONCLUSION: These data suggest that in general a low percentage of the study population has heard of EC. Health care providers and media have an important role to play in the education of women for accurate information about EC. Providing information about EC may help to prevent some unintended pregnancies and induced abortions.

Awareness of emergency contraception among university students in Mersin, Turkey.

AIM: The aim of this study is to determine the degree of knowledge, behavior and attitude of university students in Mersin towards emergency contraception (EC). MATERIAL & METHODS: This cross-sectional study was carried out among the students of the University of Mersin in December 2008. One thousand and forty-two voluntary students participated in this study and answered the questions presented in the self-administered questionnaire. The questionnaire consisted of demographic information and the students' awareness, knowledge and use of EC. RESULTS: The study sample consisted of 532 males and 510 females. The mean age of the participants was 20.4 ± 1.8. Overall, 149 (14.3%) students were aware of EC, and among those, 125 (83.9%) students correctly identified 72 h as the time limit for the methods to be used. The main sources of knowledge about EC were schools (38.9%), friends (18.8%), healthcare providers (17.4%), media (16.1%) and other sources (8.7%). EC awareness was positively associated with female gender, age, studying Health Sciences, father's level of education and level of monthly income. A total of 37 respondents (3.6%) reported that they had unprotected intercourse. Only 20 students or their partners had previously used emergency contraceptive pills. CONCLUSION: Awareness and knowledge of EC was low among the students of Mersin University. Our results demonstrated that males are less aware about EC when compared to females. We strongly recommend that education and counseling about sexual health and family planning be offered to this age group.

Rubella seroprevalence in women in the reproductive period, Mersin, Turkey.

The aim of this study was to determine the rubella seroprevalence in women of reproductive age. This cross-sectional study was conducted on women aged 15-49 years. Serologic studies were performed by using the ELISA method. The number of women enrolled in the study was 607, the mean age was 30.7+/-9.3 years and 13.2% of the participants were living in the rural area. Rubella seroprevalence was 55.0%. This ratio was 77.5% in women living in the rural area (p<0.001). There were no statistically significant correlations between immunity to rubella and other socio-demographic characteristics. In conclusion, women in this age group are advised to have a single dose of rubella vaccination in order to avoid CRS before pregnancy.

Determination of depression risk factors in children and adolescents by regression tree methodology.

We used a regression tree method (RTM) to determine risks of depression in children/adolescents. The survey records of 4,143 children/adolescents in a study based in Mersin, Turkey served as data in this study, and multi-step, stratified, and cluster sampling were used. Effects of 24 variables (sex, smoking, parental problems, etc.) were evaluated on depression scores. The Child Beck Depression Inventory (CBDI) was used to determine the level of depression. Subjects were into 12 different groups based on magnitudes of mean depression scores. The interactions among 7 variables determined to be risk factors are shown on a schema. The STATISTICA (ver.6.0) package program was used for all computations. Although traditional statistical methods have often been used for analysis in this field, such approaches are associated with certain disadvantages such as missing values, ignorance of interaction effects, or restriction of the shape of the distribution. To avoid such disadvantages, we therefore suggest the use of the RTM in studies involving numerical-based outcome variables and for the investigation of a large number of variables and it may be more effective than traditional statistical methods in epidemiological studies which determine risk factors.

A cross-sectional prevalence study of depression at various times after delivery in Mersin province in Turkey.

BACKGROUND: Postpartum depression (PPD) is defined as a major depression occurring after delivery. Depression in mothers postpartum may affect the development of the infant and life quality of the mother negatively. In this study, PPD prevalence in the first 2 months after delivery was compared with the prevalence in later periods. METHODS: This study was conducted in 2001 in the province of Mersin in Turkey. In-home questionnaires were given to nonpregnant married women age 15-44 years from primary healthcare centers identified through a multistage, stratified sampling method. Depression was defined as a score of 13 or higher on the Edinburgh Postpartum Depression Scale (EPDS). RESULTS: Data were available on 1447 women. PPD prevalence was 29.0% at 0-2 months, 36.6% at 3-6 months, 36.0% at 7-12 months, and 42.7% >or= 13 months postpartum. PPD prevalence in the 0-2-month postpartum period was lower than in the other groups (F = 4.6, p < 0.01). The prevalence increased with the time since delivery. When compared with the prevalence in months 0-2, PPD risk was 1.41 times greater in months 3-6, 1.37 times greater in months 7-12, and 1.82 times greater in months >or=13 (chi-square for trend test = 11.7, p < 0.001). CONCLUSIONS: In this Turkish population, PPD prevalence was substantial at all time points. The prevalence was at its lowest level before the second postpartum month and increased with time. The decrease in the intensive social and physical support given to the mother immediately after delivery may explain this trend.
