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.

The linear trend of headache prevalence and some headache features in school children.

The objectives of this study were to determine the age and sex dependent linear trend of recurrent headache prevalence in schoolchildren in Mersin. A stratified sample composed of 5562 children; detailed characteristics were previously published. In this study the prevalence distribution of headache by age and sex showed a peak in the female population at the age of 11 (27.2%) with a plateau in the following years. The great stratified random sample results suggested that, in addition to socio-demographic features, detailed linear trend analysis showed headache features of children with headache have some specific characteristics dependent on age, gender and headache type. This study results can constitute a basis for the future epidemiological based studies.

Intra-articular injection of tenoxicam in osteoarthritic knee joints with effusion.

Thirty patients who had grade II to III osteoarthritis according to Kellgren-Lawrence system and presenting with acute effusion of the knee joint were randomly assigned to 2 groups. All patients were treated with aspiration of the synovial fluid, cold application, and rest. Fifteen patients received an intra-articular injection of tenoxicam 20 mg following aspiration. The other group was administered oral tenoxicam 20 mg a day for 10 days. Patients were examined at 2, 4, and 8 weeks and then in 3-month intervals. At followup visits, pain was assessed using visual analog scale: range of motion, and effusion of the knee joint were recorded. A repeated measure test was used to determine the significance of changes in pain and mobility between the groups. Student's Neyman Keuls test was used to determine the significance of differences within the groups. Chi-square test was used for the number of episodes. The intra-articular injection group had more rapid pain relief than the oral treatment group (P < .01). At the end of 1 year, the number of effusions was significantly lower in the intra-articular treatment group (P < .01). These results indicate that intra-articular injection of tenoxicam provides rapid pain relief in the patients with acute flare-up of knee osteoarthritis and helps to prevent effusion.

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.

Risk factors for depression in the first postnatal year: a Turkish study.

BACKGROUND: The aim of the study was to identify risk factors for depression and to estimate its prevalence in postnatal mothers. METHODS: This cross-sectional and multi-centre study was carried out on 1,350 Turkish women in their first postnatal year. Measures included a structured questionnaire and the Turkish version of the Edinburgh Postnatal Depression Scale (EPDS). RESULTS: Of the women, 31.1% had a score of 13 or higher on the EPDS. The mean score and standard deviation was 9.8+/-5.7. In the multivariate analysis, EPDS scores were significantly associated with economic status, access to support from family members and close friends, emotional distress at the pregnancy, whether the pregnancy was planned, health problems during pregnancy, the perceived standard of baby care after delivery, and mental disorder before and during pregnancy. CONCLUSION: The prevalence of EPDS-based depression among Turkish women in postnatal the period was high, and was associated with several social, economic and demographical factors.

Prevalence and factors affecting headache in Turkish schoolchildren.

BACKGROUND: Headache is a public health problem affecting life quality negatively. The present cross-sectional, selective (2nd-5th grades) study was conducted to determine the prevalence of recurrent headache in schoolchildren in Mersin, a city of Turkey. METHODS: A stratified sample of 5777 students was selected to be representative of the city's schoolchildren population. After the data quality control process, the study sample was reduced to 5562 schoolchildren. RESULT: The prevalence of recurrent headache was 49.2% (2739/5562). Among the studied population 24.7% had tension-type headache and 10.4% had migraine. Girls had significantly more frequent headache than boys. Binary logistic regression analysis found that increasing age, female gender, low socioeconomic status of family, low education level of mother, and positive family history of headache (father, mother, siblings, second degree relatives) had a statistically significant effect on the presence of headache in children. Additionally, having travel sickness had a statistically significant effect on schoolchildren headache (P = 0.000). CONCLUSION: Headache is a common health problem among schoolchildren in Mersin, which merits increased attention and detailed multicentre epidemiological and clinical studies.

Are parents aware of their schoolchildren's headaches?

BACKGROUND: The objective of this study is to determine parents' awareness of their children's headaches and to evaluate some of the factors that affect this awareness. METHODS: The subjects of the study are 2601 children who were diagnosed with headache. Data on the children and the parents was collected using a detailed data form. The diagnosis of headache in children was made on the basis of the criteria of the International Headache Society (IHS). If the parents of a child diagnosed with headache reported that their child had headache, the parent was evaluated to be aware of his/her child's headache. In the statistical analyses, chi-square and binary logistic regression were used. RESULTS: Almost 74% of parents were aware of their children's headache. It was found that migraine type headache, female gender, being the first child of the family, travel sickness of children, the presence of headache history in one of the family members; the number of family members and mother's age are factors that affect the awareness level of parents. It was also revealed that parents who do not work outside are more aware of their children's headache and that educational and financial status do not have any effect on the degree of awareness. CONCLUSIONS: In a city like Mersin, which is economically well developed when compared with the rest of the country, one quarter of the parents are not aware of their children's headache.

Suicide attempts and risk factors among children and adolescents.

The purpose of this study was to determine the prevalence of suicide attempts, and to identify the risk factors for suicide attempts in Turkish children and adolescents between the ages 10 and 20 years. Multi-step, stratified, cluster sampling was used. A stratified sample of 4256 students was selected as representative of the city's school children population. Data was obtained with a pair of structured questionnaires designed to evaluate the presence and risk factors of suicide attempts, both in the children and adolescents and their parents. These questionnaires investigated family environment, subject characteristics, and various risk factors for suicide attempts. Child Beck Depression Inventory (CBDI) was administered to all children and adolescents. After the data quality control process, the study sample was reduced to 4143 children and adolescents. Children and adolescents were divided two groups according to the experience or non-experience of suicide attempts: group 1 (n=80) and group 2 (n=4063), respectively. Three categories of independent variables were assessed: adolescent, family, and socioeconomic characteristics. Logistic regression models were based on the children and adolescents and on parent reports. The prevalence of suicide attempts as reported by the children and adolescents was 1.93% (n=80). The mean age of group 1 was higher than that of group 2 (p=0.002, t=-3.172), as was the mean score of CBDI (p=0.000, t=-9.083). Logistic regression analysis indicated that having problems with parents, using illicit drugs, and psychiatric problems in relatives best predicted suicide attempts in Turkish children and adolescents.

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.

The prevalence of pediculosis capitis in schoolchildren in Mersin, Turkey.

BACKGROUND: Pediculosis capitis is an endemic parasitosis affecting many countries of the world. The aim of this study was to investigate the incidence of head lice infestation in Mersin, Turkey. METHODS: A total of 5318 elementary schoolchildren, aged 8-16 years, were examined for the presence of Pediculus capitis. If any evidence of head lice was detected, such as live or dead eggs, or nits, the child was considered to be infected. The following details were recorded for each child: age, sex, family size, monthly income, number of siblings, parents' education, presence or absence of social security of the family, pet (cat or dog) ownership, and frequency of hair washing (per week). The chi-squared test and logistic regression analysis were performed to analyze the results. RESULTS: Pediculosis capitis was detected in 360 (6.8%) children. The prevalence of infestation was significantly higher in girls (13.3%) than in boys (1.1%) (chi2 = 313.2, d.f. = 1, P = 0.000). Children aged 8-9 years exhibited a significantly lower prevalence rate than those aged 10-11 years and those aged 12 years and above. The following variables were found to be statistically significantly related to pediculosis capitis: sex, age, father's education level, and pet ownership (cat or dog). CONCLUSIONS: Our results show that the prevalence of pediculosis capitis is not very high in Mersin, Turkey, and is observed in all schools regardless of the socio-economic and personal hygiene status of the children.

The levels of serum vitamin C, malonyldialdehyde and erythrocyte reduced glutathione in chronic obstructive pulmonary disease and in healthy smokers.

There is an increasing interest in the concept that oxidant/antioxidant imbalance plays a role in the pathogenesis of chronic obstructive pulmonary disease (COPD). However, most of the studies are concentrated on the local antioxidant/oxidant balance. In this study, we investigated the oxidant/antioxidant balance in systemic circulation of patients with COPD. Serum malonyldialdehyde (MDA), vitamin C and erythrocyte reduced glutathione (GSH) were determined in patients during acute exacerbation and during the stable phase of the disease, and compared with age- and sex-matched healthy controls. The levels of serum MDA, vitamin C and erythrocyte GSH were determined according to Yagi, Beutler and Bauer et al., respectively. Serum MDA levels were significantly higher in patients compared to controls, and during acute exacerbation compared to the stable phase. MDA levels in patients with acute exacerbation and in those in stable phase were also higher than in controls. We found significantly decreased levels of erythrocyte GSH and serum vitamin C in patients with acute exacerbation and stable COPD compared to controls. Although smoking caused an increase in oxidative stress in controls, the measured parameters were not affected by smoking in the patient group. In conclusion, there is a systemic oxidant/antioxidant imbalance in COPD, and this imbalance is probably independent of smoking.
