Relationship Between Types of Information, Dental Anxiety, and Postoperative Pain Following Third Molar Surgery: A Randomized Study.

PURPOSE: Third molar (M3) extraction is an anxiety-provoking procedure. Information mode delivery may affect patients' anxiety level and postoperative sequelae. This study determined the relationship between information types, dental anxiety, and postoperative pain following mandibular M3 extraction. METHODS: Patients (aged 18 to 35 years) requiring M3 extraction under local anesthesia were recruited into this prospective randomized study conducted in Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife. Patients were randomized to two groups; verbal or audiovisual depending on M3 extraction information received. Primary outcome variable (difference in anxiety between groups) was assessed with State-Trait Anxiety Inventory (STAI-S) and Modified Dental Anxiety Scale(MDAS). Pain recorded on postoperative days (PODs) 1, 3, and 7 using the Visual Analog Scale was the secondary outcome. Other covariables include biodata, impaction types, and difficulty indices. Data analysis was descriptive and bivariate using IBM/SPSS for Windows, version 23 (SPSS, Chicago, IL USA) with significance set at P < .05. RESULTS: Ninety patients referred for M3 extraction met the inclusion criteria, 45 patients in each group. The audiovisual group had significant increase in anxiety preoperatively measured by STAI-S (P = .002) and MDAS (P = .009) when compared with the verbal group. No significant differences in the STAI-S (P = .16) and MDAS (P = .216) scores were recorded at POD7. The progressive reduction in pain in both groups was not significant at POD7 (P = .746). CONCLUSIONS: Preoperative verbal information allayed anxiety compared to real life audiovisual information in M3 patients. These findings will provide a baseline reference data for subsequent research in our environment.

Sleep quality and its relationship with school schedules and mental health of Nigerian secondary school adolescents.

STUDY OBJECTIVES: This study aimed to determine the sleep quality of in-school Nigerian adolescents and its association with their schooling and mental health outcomes. METHODS: The study was a descriptive cross-sectional study. It was conducted among adolescents attending public and private secondary schools within the Ife Central Local Government, Osun State, southwestern Nigeria. A multistage sampling technique was used to select study participants. The Pittsburgh Sleep Quality Index, 9-item Patient Health Questionnaire (PHQ-9), and 7-item General Anxiety Disorder questionnaires were used to determine sleep quality, depression, and anxiety, respectively. RESULTS: We studied 448 adolescents aged between 10 and 19 years with a mean age of 15.0 ± 1.8 years. The majority of our respondents (85.0%) had poor sleep quality. More than half of the respondents (55.1%) had insufficient sleep during weekdays, while only 34.8% had insufficient sleep during weekends. The school closing time and school type showed a statistically significant association with sleep quality (P = .039 and .005, respectively). The odds of having poor sleep quality increased by 2-fold among adolescents in private schools when compared with those in public schools (adjusted odds ratio = 1.97, 95% confidence interval = 1.069-3.627). Using multiple linear regression, only depression showed a statistically significant association with sleep quality at 95% confidence interval (CI = 0.073 to 0.219, P < .001), such that for every unit change in depression scores (PHQ-9), there will be a corresponding increase of 0.103 in sleep quality. CONCLUSIONS: Sleep quality is poor in adolescents and adversely associated with their mental health. This should also be addressed in the development of appropriate interventions.

Sleep quality and psychological distress among undergraduate students of a Nigerian university.

OBJECTIVES: The objectives of the study were to assess the sleep quality of undergraduate students in a Nigerian University, to determine its association with psychological distress, and to evaluate some of the factors associated with poor sleep quality among the students. METHODS: It is a descriptive cross-sectional study conducted among the undergraduate students of Obafemi Awolowo University, Ile-Ife. The multistage sampling method was used to select 520 study participants, and a self-administered instrument including a questionnaire on sociodemographic characteristics, Pittsburgh Sleep Quality index, General Health Questionnaire, and Hospital Anxiety-Depression Scale was administered. RESULTS: Out of 520 students who gave consent to participate in the study, 505 students (97.1%) returned a fully-completed questionnaire. Half of the students (50.1%; 95% confidence interval [CI], 45.7-54.5%) had poor sleep quality, with a minority (5.7%) taking sleep medications at least once or twice a week. About one-fourth (24.4%; 95% CI, 21.7-27.1%)) had psychological distress. Among the demographic factors, the year of study (χ2=13.80 [P<.01]) had significant association with poor sleep quality. Presence of psychological distress and symptoms of depression and anxiety were also significantly associated with poor sleep quality. The year of study, psychological distress, and anxiety symptoms were significant predictors of poor sleep quality among the students. CONCLUSION: The strong association between psychological distress and quality of sleep further underscores the benefit of advocating for habits that can improve optimal mental health and sleep quality among the undergraduate students.

Caregiver burden in families of patients with depression attending Obafemi Awolowo University teaching hospitals complex Ile-Ife Nigeria.

OBJECTIVE: The objective of this study was to assess caregiver burden among relatives of patients on treatment for depressive disorder attending the psychiatry outpatient clinic of the Obafemi Awolowo University Teaching Hospitals Complex, Ile Ife, Nigeria. METHODS: A cross sectional design was used. Hundred caregivers of patients with ICD-10 diagnosis of depression, on outpatient treatment for at least six months were recruited from the psychiatric outpatient clinic. Caregivers completed a semi-structured socio-demographic questionnaire, the Zarit Burden Interview and General Health Questionnaire (GHQ) 12. Descriptive statistics were used to describe socio-demographic variables; association between dependent and independent variables were assessed using Pearson's correlation, chi squared and t test as appropriate. RESULTS: The mean ZBI score was 41.32 (S.D. = 9.82), 45% of respondents reported moderate to severe burden, spouses constituted 57% of caregivers. Age at onset of depression (t = 2.46, P = .02) number of hospitalization,(χ(2) = 9.82, P = 0.001), and current active symptoms (χ(2) = 36.1, P = .001) were all significantly associated with burden score. Severity of symptoms (r = 0.48, P < .01) and age at onset of illness (r = -0.26, P < .01) both correlated significantly with burden scores, while GHQ score among caregivers also correlated significantly with burden scores (r = 0.52, P < .01). CONCLUSIONS: Caregivers of depressed patients experience moderate to severe burden. Caring for the depressed need to change from a patient focused approach to a combined patient and caregiver approach.

Psychological reactions to amputation in a sample of Nigerian amputees.

OBJECTIVE: The study compares psychological symptoms between amputees and other orthopedic patients. METHOD: Forty-two consecutive amputees were interviewed between 7 and 28 days after amputation, and an equal number of other orthopedic patients matched for age, sex, marital status, and occupation were used as controls. Each respondent completed a sociodemographic questionnaire, while clinical variables were obtained from the case notes. Respondents also completed the General Health Questionnaire, State Trait Anxiety Inventory, and the Zung Self-Rating Depression Inventory. RESULTS: The mean age of amputees in this study was 42.33 years (S.D.=15.89 years), and the average weekly income is #3500.00 ($29.00). Anxiety and depressive symptoms were high among amputees (64.3% and 59.5%, respectively) compared to other orthopedic patients (14.3% and 12.0%, respectively). Correlation analysis showed that there was significant correlation between anxiety and age (negative), marital status, and level of education, while depressive symptoms significantly correlated significantly with age (negative) and marital status. CONCLUSION: Psychological symptoms are high in this sample of amputees, indicating the importance of social and emotional support for these patients.
