Bullying victimization among adolescents: Prevalence, associated factors and correlation with mental health outcomes

INTRODUCTION

Knowledge of the risk factors of bullying victimization in adolescents is crucial for the implementation of preventive measures. This study aimed to determine the prevalence and associated factors of bullying victimization and to identify its correlation with mental health outcomes among middle school students in Tunisia.

METHODS

A cross-sectional study was conducted using a multi-stage cluster sampling technique to recruit a sample of 1111 students from 10 middle schools in El kef (Tunisia). The revised Olweus Bully/Victim Questionnaire was used to assess the prevalence and types of bullying victimization and the perceived efforts of others to counteract bullying. The Strengths and Difficulties Questionnaire (SDQ) was used for screening emotional and behavioral problems. Multivariate logistic regression analysis was conducted to determine associated factors of bullying victimization. Additionally, we tested whether emotional and behavioral problems were present for bullying victims.

RESULTS

The findings reported that 45.8% (95%CI = 45.5-46.0), of the total number of participants experienced school bullying victimization. Multivariate logistic regression analysis, revealed that repeating a grade (OR = 1.82, 95%CI = 1.31-2.54), having a working father (OR = 17.68; 95%CI = 2.29-136,15), and having a working mother (OR = 1.88, 95%CI = 1.39-2.53) were the factors significantly associated with bullying victimization. Nevertheless, a higher mother's educational level (OR = 0.76, 95%CI = 0.67-0.88) was a protective factor against bullying victimization. The self-reported SDQ revealed that the total difficulties score was significantly higher among victims (17.46 ± 5.30 vs. 20.86 ± 5.06, p<0.01).

CONCLUSIONS

This study showed that the prevalence of bullying in middle schools was high and it significantly led to mental health problems. National policies for bullying prevention within schools are potentially needed. Improving students' problem-solving and soft skills is also essential.

Impact of a tailored-care education programme on maternal and neonatal outcomes in pregnant women with gestational diabetes: a randomized controlled trial

Introduction

patient education is a key component of positive pregnancy and childbearing experiences, especially in women with gestational diabetes (GDM). Scant studies assessed the impact of tailored self-care education on pregnancy outcomes in pregnant women with gestational diabetes mellitus (GDM). This study aimed to assess the effect of a tailored-care education programme on maternal and neonatal outcomes in pregnant women with GDM during pregnancy and at birth.

Methods

this was a randomized controlled trial conducted in a university hospital in the centre of Tunisia, from October 2020 to May 2021. The intervention group (n=61) received a self-care education programme with the usual care plan for GDM, while the control group received only the usual care plan (n=60). This trial was registered in the Pan African Clinical Trials Registry under the registration number PACTR202106591503674.

Results

at baseline, there was no significant difference between groups in terms of sociodemographic and clinical characteristics. The findings showed that the intervention significantly reduced maternal and neonatal hospitalizations (p=0.000), caesarean section (p=0.002), preterm labour (p=0.002), macrosomia (p=0.000), foetal distress (p=0.001), newborn respiratory complication (p=0.01) and hypoglycaemia (p=0.000).

Conclusion

implementing a tailored-care education for pregnant women with GDM had a positive impact on mother and infant clinical outcomes. Midwives and endocrinologists should use this programme to reduce maternal and neonatal complications during and after pregnancy.

Shape transition and coalescence of Au islands on Ag (110) by molecular dynamics simulation

We have used molecular dynamics simulations based on many body semi-empirical potentials described by the embedded atom method, to analyze and understand the diffusion and coalescence phenomena of Au-clusters during the heteroepitaxial growth on Ag (110) surface. Temperature ranging from 300 to 700 K were considered. In this study, we examined the heterogeneous system Au_n/Ag(110), where n is the number of atoms in each cluster/island (with n = 15, ….35). Our results show that the clusters diffuse on the Ag (110) surface via different diffusion processes, namely, the exchange mechanism and the simple jump, which generate a 2D to 3D transition. Formation and adsorption energies of clusters with different sizes have been computed using static simulations. The dynamic study of coalescence for two islands of system Au₁₅; Au_0 - 9/Ag(110) at different temperatures makes it possible to deduce the detail of cluster shape and the influence of its temperature on the stability of the system and its growth during this evolution.

Assessing the impact of a family empowerment program on asthma control and medication use in children with asthma: A randomized controlled trial

PURPOSE

In pediatric asthma, family empowerment education has been beneficial for the quality of life, pulmonary function, and family functioning. Few studies addressed the impact of a family empowerment program on asthma symptom control, acute healthcare use (AHCU), and medication use in children with asthma. This study aimed to assess the effect of a family empowerment intervention on asthma symptom control, AHCU, inhaler technique, and controller adherence in children with asthma.

DESIGN AND METHODS

A single-center study using a randomized controlled design was conducted in a university hospital in the center of Tunisia from May 2018 to September 2019. Eighty-two families were randomly assigned to the intervention group (n = 41) of 8 weeks of group training sessions, or to the control group (n = 41) of usual care education. Thirty-seven families in the intervention group and 39 families in the control group received allocated intervention at baseline. Thirty-four families in each group completed the study at the 12-month follow-up.

RESULTS

At baseline, the intervention and control groups were statistically comparable (p > .05). At follow-up, there were significant differences between the intervention and the control group in asthma symptom control, χ² (1, N = 34) = 9.950, p = .002, and inhalation technique, χ² (1, N = 34) = 5.916, p = .01. For AHCU and adherence to asthma controller, there was no significant difference between groups, χ² (1, N = 34) = 3.219, p = .07, χ² (1, N = 34) = 0.541, p = .46, respectively. The difference within time in asthma symptom control and inhalation technique was significant (p = 10^-3 , p = .001; respectively).

PRACTICE IMPLICATIONS

This study demonstrated that a family empowerment program significantly improved asthma symptom control and inhaler technique in children with asthma aged 7-17 years. This intervention could be clinically useful and time-saving for pediatric nurses.

Stress perception and associated factors among healthcare students

Introduction

Stress and its deleterious effects are currently a major topic in public health. Health care studies can be very stressful as they pose a challenge for students around the world. The aim of this study was to assess stress perception among healthcare students and to identify its associated factors.

Methods

A descriptive cross-sectional study was carried out over a five-month period (January-May 2017) among healthcare students at the Higher School of Health Sciences, University of Sousse (Tunisia), during the 2016/2017 academic year. The socio-demographic and health status data have been collected using a pre-established data collection sheet. Stress perception was assessed by the French version of the Perceived Stress Scale with 10 items (PSS-10). Factors associated with stress were examined using ANOVA and T-student tests.

Results

A total of 237 students participated in the study with a response rate of 64.40%. The average age was 20.57±1.05 with a female predominance of 90.7%. The mean of the PSS-10 total score was 31.37±4.406. A rate of 89% of cases had a perceived high-stress score. Factors associated with stress were social status (p = 0.005), housing (p = 0.01), hometown (p = 0.03), presence of a diagnosed health condition (p = 0.02), presence of eating disorder (p = 0.04), presence of sleeping disorder (p = 0.004).

Conclusions

This study reported that healthcare students had a high level of stress associated with endogenous and exogenous factors. Stress management strategies must be included in the educational curriculum in healthcare schools.

Key messages

Health care studies pose a challenge for students around the world. Healthcare students had a high level of stress associated with endogenous and exogenous factors.

Association between smoking cessation and quality of life among patients with COPD in Tunisia

Introduction

Smoking cessation is the most important step to limit the complications of chronic obstructive pulmonary disease (COPD). Outcomes from studies that assessed the association between health-related quality of life (HRQL) and smoking cessation have been controversial. This study aimed to assess the relationship between HRQL and smoking cessation in patients with COPD in Tunisia.

Methods

A cross-sectional study was carried out in the two main primary care centers in the center of Tunisia over a period of three months (April-June 2016). Clinic and socio-demographic data were collected from patients' records. HRQL was assessed by the Medical Outcomes Study Short-form 36 (SF-36). This instrument is composed of two dimensions: physical and mental components. The questionnaire outcomes were described as means and standard deviation. T-test was performed to assess the statistical difference between the dependent and categorical variables.

Results

A total of 249 COPD patients participated in the study with a mean age of 67.77±11.13. Of this sample, 169 (67.9%) ceased smoking. The average period of smoking cessation was 10 years. The mean of total HRQL score in patients who ceased smoking was lower in comparison to patients who did not quit smoking (40.65±24.49, 43.37±24.49; respectively). The T-test reported a significant difference between the physical component of HRQL and smoking status. Patients with current smoking status had a better physical component score in comparison with patients who quit smoking (43.76±22.62, 37,86±18.21, p = 0.04, respectively). No significant differences were found between smoking cessation, mental component, and HRQL total score (p = 0.89, p = 0.39; respectively).

Conclusions

This study revealed that smoking cessation was associated with the physical component of HRQL. The smoking dependence in patients with COPD could explain this finding. Health care professionals should work harder on effective smoking cessation strategies.

Key messages

These findings suggested that HRQL was better among patients who did not quit smoking. Patients who did not cease smoking reported better physical status and poorer mental status in comparison with patients who quit smoking.

Quality of Life Determinants in Children and Adolescents with Mild to Moderate Asthma in Tunisia

Chronic childhood asthma is a leading cause of poor quality of life. Factors associated with this major asthma outcome were controversial. The aim of this study is to assess the quality of life of children and adolescents with mild to moderate asthma and to determine the factors associated with quality of life impairment in this population. This was a descriptive study carried out in the pediatric outpatient clinic of a University Hospital in the center of Tunisia over a period of 3 months (April-June 2018). Participants were children with mild to moderate asthma aged 7 to 17 years. The Pediatric Asthma Quality of Life Questionnaire was used to assess quality of life. Binary logistic regression was performed to identify predictors of asthma-related quality of life. A total of 90 children participated in the study. Almost 68% of children were aged 7 to 11, and nearly 32% were adolescents. The mean of PAQLQ total score was 4.7 ± 1.2. The final logistic regression model demonstrated that asthma symptoms control had the greatest impact on quality of life, followed by acute health care use in the past 12 months (p = .007; p = .01, respectively). The child gender and the parent's quality of life were also associated with the child's quality of life (p = .02; p = .008, respectively). This study revealed that children and adolescents with mild to moderate asthma had a moderate quality of life score. Asthma symptoms control, acute health care use, gender, and parent's quality of life determined the quality of life of children with asthma. Family-based asthma training programs that target family functioning and asthma outcomes are required.

Factors Associated with Acute Health Care Use in Children and Adolescents with Asthma

Asthma is a leading cause of acute health care use (AHCU) as defined by hospitalization and emergency department visits (ED). Little was known about factors associated with asthma-related AHCU. This study aimed to identify factors determining AHCU in children and adolescents with asthma. A descriptive study was conducted among children with mild to severe asthma referred to the pediatric outpatient clinic of "Farhat Hached" University Hospital of Sousse (Tunisia) over a period of three months (April-June 2018). We collected data regarding clinical information, the number of hospitalizations and ED visits related to asthma in the past 12 months, asthma management behaviors, and quality of life of children. Multivariable logistic regression was performed using SPSS (20.0). A total of 90 children have participated in the study. The percentage of children aged 7 to 11 years was higher than the percentage of adolescents aged 12 to 17 years (67.8%; 32.2%, respectively). The final logistic regression model demonstrated that asthma severity and inhaler technique increased the odds of AHCU (OR a = 4.6; 95% CI: 1.1-18.1; p = .03, OR a = 2.9; 95% CI: 1.1-7.8; p = .02, respectively). Also, increased quality of life score reduced the odds of AHCU (OR a = 0.6; 95% CI: 0.4-0.9; p = .01). These results suggest that the organization of programs targeting the management of these factors can reduce the workload on hospital services and emergencies.

Estimation of direct cost related to asthma among school-age children with asthma

Background

Childhood asthma still imposes a substantial burden on the health care system and community. Its management requires a significant direct cost. Several factors can influence the cost of asthma management, particularly severe asthma. There is scant information about the predictors of asthma-related cost. Thus, the purpose of this study was to estimate direct asthma-related cost among children with chronic asthma and to identify factors that have the greatest contribution to change it.

Methods

This cross-sectional study was carried out in Farhat Hached University Hospital in Sousse (Tunisia, Africa) over a period of three months (April-June 2018) among children with asthma aged 7-17 years. The direct cost was defined as the costs of health resources utilization and medication related to asthma in the past 12 months. Purchasing power parity technique was used to convert TND to USD. Multiple linear regression was performed to examine the association between dependent and independent variables.

Results

A total of 90 subjects participated in the study. The mean age was 9.81±2.56 and 55.6% were male. The annual mean of the total direct cost was USD 616.71±454. Multivariate analysis showed that the severity of asthma, inhalation technique and emotional domain of QOL predict asthma cost and that the latter was the best predictor (p = 0.005, p = 0.03, p = 0.004, respectively). This data indicates that for one child with mild asthma, correct inhaler technique, and moderate impairment of emotional function QOL domain, estimated asthma direct cost was equal to 1035.21 USD per 12 months.

Conclusions

This study showed that higher severity of asthma, incorrect inhaler technique and a lower score of emotional function increased direct cost related to asthma. These results are useful for health care providers and community since they provide information about the impact of modifiable risk factors on direct asthma cost.

Key messages

For one child with mild asthma, correct inhaler technique, and moderate impairment of emotional function QOL domain, estimated asthma direct cost was equal to 1035.21 USD per 12 months. Higher severity of asthma, incorrect inhaler technique and a lower score of emotional function increased direct cost related to asthma.

Determinants and outcomes associated with decisions to deny intensive care unit admission in Tunisian ICU

Introduction

intensive care unit (ICU) beds are a scarce resource, and admissions may require prioritization when demand exceeds supply. However, there are few data regarding both outcomes of admitted patients to intensive care unit (ICU) in comparison with outcomes of not admitted patients. The aim of this study was to assess reasons and factors associated to refusal of admission to ICU as well as the impact on mortality at 28 days and patients' outcomes.

Methods

Single-center, cross-sectional descriptive study conducted in 8-bed Medical ICU at a Tunisian University hospital. All consecutive adult patients referred for admission to ICU during 6 months were included. We collected demographic data, ICU admission/refusal reasons, co-morbidity and diagnosis at time of admission, mortality probability model (MPMII0) score, day and time of admission, request for admission and mortality at 28 days.

Results

327 patients were evaluated for ICU admission and 260 were refused to ICU (79.5%). Patients refused because of unavailability of beds represented 50% and patients considered “too sick to benefit” represented 22%. Multivariate analysis showed that the presence of acute respiratory failure and request by direct contact in the unit were independently associated to admission to ICU (OR: 0.15; 95% CI: 0.07-0.31 and OR: 0.16; 95% CI: 0.08-0.31, respectively). Higher mortality rates were shown in patients “too sick to benefit” (80.7%) and unavailable beds (26.56%).

Conclusion

Refusal of ICU admission was correlated with the severity of acute illness, lack of ICU beds and reasons for admission request. ICU clinicians should evaluate their triage decisions and, if possible, routinely solicit patient preferences during medical emergencies, taking steps to ensure that ICU admission decisions are in line with the goals of the patient. Ultimately, these efforts will help ensure that scarce ICU resources are used most effectively and efficiently.
