Alcohol use disorders in multidrug resistant tuberculosis (MDR-TB) patients and their non-tuberculosis family contacts in Nigeria.

INTRODUCTION: the main aim of this study was to determine the prevalence and associated factors of alcohol use disorder (AUD) in patients with Multi-Drug Treatment-Resistant Tuberculosis (MDR-TB) compared with their non-tuberculosis control, and its association with disease pattern and associated medical comorbidities. METHODS: MDR-TB patients (128) and their respective caregivers were interviewed in a treatment unit in Nigeria. Diagnosis of AUD was made using the Structured Clinical Interview for DSM-IV Axis I Disorder, information was obtained on the severity of the TB and associated health problems. RESULTS: prevalence of AUD was (21.9%) and was significantly higher among cases than in controls (2.3%), p = 0.006. Severe TB, OR = 3.33 (1.56-6.83), hematological diseases, OR = 2.34 (1.06-4.33) and HIV/AIDS, OR = 3.01 (1.67-7.01) were the strongest predictors of AUD at 95% CI. Conclusion: AUD was highly prevalent in MDR-TB and was associated with certain medical comorbidities and increased severity of the illness.

Shisha smoking in selected nightclubs in Nigeria.

INTRODUCTION: Shisha consumption is a growing public health issue all over the globe and public health awareness about its deleterious health consequences is still not sufficiently raised. METHODS: In this location-based study of nightclubs in Ibadan, Nigeria, 633 patrons of selected nightclubs were interviewed in order to obtain information on prevalence, correlates and predictors of shisha smoking. RESULTS: The overall prevalence of shisha smoking was 7.1%. The age of initiation into shisha smoking was lower among women, p = 0.03, but men were significantly more likely to be more frequent users, daily or weekly users, p < 0.001 and also to be current cigarette smokers, p = 0.03. There was no significant gender variability in the stage of readiness to quit. Regression analysis showed that after adjusting for age, the predictors of shisha smoking were: cigarette smoking, OR = 4.83, 95% CI (1.49-15.70) and more than 12 years of education, OR = 7.55, 95% CI (1.88 - 30.37), while being a rural dweller was a protective factor, OR = 0.05, 95% CI (0.01-0.20). CONCLUSION: Shisha smoking has emerged as a prevalent public health issue in Nigeria. There is a need for an immediate response from policy providers towards shisha smoking intervention in Nigeria.

Beta-cell Function and Metabolic Clearance Rate of Glucose in Patients with Major Mental Health Disorders on Antipsychotic Drug Treatment.

BACKGROUND: Insulin resistance and metabolic alteration continue to be essential features of major mental health disorders (MMHD) with poorly understood and multifaceted mechanisms. This study was carried out to provide information on insulin resistance, beta-cell function, metabolic clearance rate of glucose and their possible interplay with duration of antipsychotic use in patients with major mental health disorders. METHODOLOGY: Plasma levels of glucose and insulin were determined in 124 patients with MMHD after an overnight fast and at 30 and 120 min of standard Oral Glucose Tolerance Test. Thereafter, indices of insulin resistance, beta-cell function and estimated metabolic clearance rate of glucose (eMCR) were calculated appropriately. Statistical analysis was done using ANOVA, Kruskal Wallis, independent Student's t-test and Mann-Whitney U. P-values less than 0.05 were considered as statistically significant. RESULTS: Metabolic factors (fasting and postprandial glucose and insulin), indices of insulin sensitivity and ß-cell function were not significantly different when patients with schizophrenia, bipolar and depression were compared with one another. Postprandial insulin level at 30 min (30 min PPI), estimated First and Second Phases of Insulin Release (eFPIR, eSPIR) were significantly lower in patients on atypical antipsychotic drugs [18.15 (3.57-40.35) µIU/ml), 617.63 (320.06-911.31) pmol/l, 180.30 (114.82-249.39) pmol/l] compared with patients on typical antipsychotic drugs [27.48 (13.33-47.68) µIU/ml, 767.69 (530.58-1198.35) pmol/l, 209.89 (154.01-310.97) pmol/l]. Furthermore, the mean waist circumference and body mass index were significantly higher in patients who have been on anti-psychotic drug for more than 10 years compared with patients with less than 5 years history of anti-psychotic use. eMCR of glucose progressively declined with increasing duration of antipsychotic use and it was significantly lower in patients who have been on antipsychotic drugs for more than 10 years [8.09 (5.90-9.44) ml.kg-1.min-1] compared with patients who have been on the drugs for less than 5 years [9.03 (7.47-10.04) ml.kg-1.min-1]. CONCLUSION: Patients on atypical antipsychotics seem to have insulin secretion phases consistent with ß-cell dysfunction. Also, chronicity of antipsychotic treatment predisposes patients with major mental health disorders to central adiposity and low metabolic clearance rate of glucose, a forerunner of glucose intolerance.

Vitamin D Levels in Different Severity Groups of Schizophrenia.

BACKGROUND: Vitamin D deficiency (VDD) continues to be associated with schizophrenia, but there is the dearth of information on the relationship between the severity of schizophrenia and plasma levels of vitamin D. This study, therefore, determined the plasma levels of vitamin D in different severity groups of schizophrenia. MATERIALS AND METHODS: Plasma level of vitamin D was determined in 60 patients with schizophrenia and 30 apparently healthy individuals who served as controls. Patients with schizophrenia were classified into mildly ill, moderately ill, markedly ill, and severely ill groups using the Positive and Negative Syndrome Scale (PANSS). RESULTS: The mean level of vitamin D was significantly lower in patients with schizophrenia compared with the controls. Similarly, there was a significant association between VDD and schizophrenia. The mean plasma levels of vitamin D were not significantly different when the mildly, moderately, markedly, and severely ill groups were compared with one another and there was no significant correlation between vitamin D level and PANSS scores. Furthermore, patients on atypical antipsychotics had an insignificantly lower level of vitamin D compared with the patients on typical antipsychotics. CONCLUSION: It could be concluded from this study that patients with schizophrenia have low plasma vitamin D level which does not appear to be associated with the severity of schizophrenia and type of antipsychotics. Therefore, regular screening for vitamin D status of patients with schizophrenia is suggested in order to allow for the institution of appropriate clinical intervention when necessary.

Profile and Determinants of Disability in Psychotic Disorders in Nigeria.

We compared profile and predictors of disability among 210 patients with schizophrenia, schizoaffective disorder, bipolar I disorder with psychosis and depression with psychosis, respectively in a Nigerian clinical population, using the WHO Disability Assessment Schedule, (2.0). Severity of psychosis was determined with Positive and Negative Symptoms Scale, functioning was assessed using the Global Assessment of Functioning Scale, medication adherence with the Medication Adherence Questionnaire. Analyses were by SPSS 20.0. There were remarkable differences in the predictors of disability across these psychotic disorders. The findings strengthens the significance of psychosocial rehabilitation in patients with psychosis as clinical remission and medication adherence did not equate functional recovery.

Medical Co-morbidities Among Patients with Severe Mental Illnesses in a Community Health Facility in Nigeria.

To examine prevalence of medical comorbidity (MCM) in schizophrenia (n = 1310) and in bipolar disorder (n = 1307) and the association of high burden of MCM (≥3 MCM) with duration of untreated illness, number of episodes, functioning, poly-medication and lifetime hospitalization for the mental disorder. Participants were recruited from a private psychiatric facility in Ibadan, Nigeria between 2004 and 2013 and enquiry made about the lifetime occurrence of 20 common chronic diseases including common tropical diseases. Psychiatric diagnosis was made using the Structured Clinical Interview for DSM IV Axis I disorder (SCID). Except for nutritional anemia, dermatitis and intestinal Helminthiasis, patients with schizophrenia were not at higher odds of reporting MCM than those with bipolar disorder. DUI ≥2 years, episodes of illness ≥3, being on multiple neuroleptics and history of previous hospitalization were significantly associated with high burden of MCM in schizophrenia and episodes of illness ≥3, reduced functioning and history of previous hospitalization with bipolar disorder. Schizophrenia and bipolar disorder are associated with high rates of medical comorbidity. Treatment of this medical comorbidity is essential in order to improve the outcomes for patients with bipolar disorder and schizophrenia.

Community-Based Screening, Brief Intervention, and Referral for Treatment for Unhealthy Tobacco Use: Single Arm Study Experience and Implementation Success in Rural and Semi-Rural Settings, South-West Nigeria.

OBJECTIVE: To determine whether screening, brief intervention, and referral for treatment can reduce the prevalence of tobacco use in rural and semi-rural settings. DESIGN AND PARTICIPANTS: A non-randomized clinical trial with assessments at baseline and post-intervention assessments at 3 and 6 months was conducted in a rural and semi-rural district in South-West of Nigeria. A representative sample of 1203 persons consented to the study and had alcohol, smoking, and substance involvement screening test (ASSIST) administered to them by trained community health-care extension workers between October 2010 and April 2011. Follow-up participation was more than 99% at all points. INTERVENTION: Participants received a single ASSIST-linked brief intervention (BI) and referral for treatment (RT) at entry, and a booster ASSIST BI and RT at 3 months. MAIN OUTCOMES AND MEASURES: The primary outcome was self-reported scores on ASSIST. RESULTS: At baseline, out of 1203 respondents, lifetime prevalence and current prevalence of any tobacco products were 405 (33.7%) and 248 (20.6%), respectively. Of the current users, on the ASSIST, 79 (31.9%) scored 0-3 (low health risk), 130 (52.4%) scored 4-26 (moderate risk), and 39 (15.7%) scored 27+ (high risk). At 3 months, out of 1199 respondents, prevalence of current users was 199 (16.5%) and out of 1195 respondents, was 169 (14.1%) at 6 months. Prevalence of tobacco use reduced significantly at 3 months Z = -3.1, p = 0.01 and at 6 months when compared with baseline Z = 4.2, p = 0.001, but not at 6 months compared with at 3 months, Z = 2.1, p = 0.09. Multivariate analysis revealed that age at initiation of tobacco use, gender, marital status, setting of dwelling, and socioeconomic status were the only variables that were associated with current tobacco use at baseline, 3 and 6 months. CONCLUSION: A one-time BI with a booster at 3 months had a significant effect on tobacco use in persons living in community settings. This finding suggests a need for promoting the adoption of this intervention for tobacco use in rural and semi-rural community settings.

Prevalence and Correlates of Alcohol Use among a Sample of Nigerian Semirural Community Dwellers in Nigeria.

Objective. To determine the prevalence and correlates of alcohol use among a sample of Nigerian semirural community dwellers in Nigeria. Methods. In a single arm nonrandomized intervention study, the assessment of baseline hazardous and harmful alcohol use and associated risk factors was conducted in two semirural local government areas of Oyo State, Nigeria, with the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST). Participants included 1203 subjects 15 years and older, recruited between October 2010 and April 2011. ASSIST score of 0-10 was classified as lower risk scores, 11-26 as moderate risk, and 27+ as high risk. Results. Prevalence of lifetime alcohol use was 57.9% and current alcohol use was 23.7%. Current alcohol use was more prevalent among the younger age group p = 0.02, male gender p = 0.003, unmarried p < 0.01, low educational level p = 0.003, low socioeconomic class p = 0.01, unemployed p < 0.001, and the Christians p < 0.01. Of the current drinkers, the majority (69.1%) were at either moderate or high health risk from alcohol use. Conclusion. Alcohol consumption is prevalent in semirural communities in Nigeria and the majority of these drinkers are at moderate or high health risk. Screening, brief intervention, and referral for treatment for unhealthy alcohol use should be integrated into community care services in Nigerian rural communities.

Family Burden in Caregivers of Schizophrenia Patients: Prevalence and Socio-demographic Correlates.

BACKGROUND: This study aims to determine the prevalence and socio-demographic correlates of caregiver's burden in schizophrenia. MATERIALS AND METHODS: A dyad of 368 schizophrenia patients and their caregivers were interviewed. Caregiver's burden was assessed using the Yoruba-version of the FBIS and GHQ-12. RESULTS: Mean age of patients was 29.7 SD (8.6) years. Of the 368 caregivers, 81.5% were parents, mean age was 58.1 years (SD 19.6). Total mean objective FBIS score was 22.69 (6.21), 324 (85.3%) reported total objective burden and 310 (84.2%), subjective burden. There were significant differential demographic associations with caregivers' burden. CONCLUSION: Caregivers of schizophrenia patients experience enormous burden and are potential "high risk group" for mental disorders. Thus, they require comprehensive intervention in order to reduce the growing incidence of chronic enduring diseases including mental disorders.

Burnout among Nurses in a Nigerian General Hospital: Prevalence and Associated Factors.

Objective. To evaluate the prevalence and associated factors of burnout among nurses in a Nigerian general hospital. Methods. A total sampling method was utilized. Measurements. Burnout was evaluated using the Maslach Burnout Inventory; GHQ-12 was used to determine the presence of psychiatric morbidity. Results. A high level of burnout was identified in 39.1% of the respondents in the area of emotional exhaustion (EE), 29.2% in the area of depersonalization and 40.0% in the area of reduced personal accomplishment. Multivariate analysis showed that doctor/nurse conflict (OR = 3.1, 95% CI: 1.9-6.3), inadequate nursing personnel (OR = 2.6, 95% CI: 1.5-5.1), and too frequent night duties (OR = 3.1, 95% CI: 1.7-5.6) were predictors of burnout in the area of EE, doctor/nurse conflict (OR = 3.4, 95% CI: 2.2-7.6) and too frequent night duties (OR = 2.4, 95% CI 1.5-4.8) in the area of D, high nursing hierarchy (OR = 2.7, 95% CI: 1.5-4.8), poor wages (OR = 2.9, 95% CI: 1.6-5,6), and too frequent night duties (OR = 2.3, 95% CI: 2.3-4.5) in the area of RPA. Conclusions. Prevalence of burnout among these nurses was high. The government therefore needs to look into factors that will enhance nurses' recruitment and retention for effective health care delivery system.

Validation of Yoruba Version of Family Burden Interview Schedule (Y-FBIS) on Caregivers of Schizophrenia Patients.

Objective. To validate the Yoruba version of Family Burden Interview Schedule (Y-FBIS) for assessing the burden on caregivers of persons with schizophrenia. Methods. Three hundred and sixty-eight dyads of persons with schizophrenia and their caregivers were recruited from a psychiatric outpatient clinic. The (Y-FBIS) and the Yoruba version of the GHQ-12 (Y-GHQ-12) were applied to the caregivers. Patients' level of social functioning was assessed using the Global Assessment of Functioning scale. Results. All (368) caregivers were used for tests of internal consistency, 180 for interrater reliability, and another 180 for test-retest reliability. Internal consistency of the Y-FBIS was demonstrated by a significant Cronbach α of between 0.62 and 0.82 for each item. Concurrent validity of the Y-FBIS was illustrated by its significant positive correlation with Y-GHQ-12 (r = 0.633 , P < 0.01). Split-half reliability was 0.849. Intraclass correlation coefficient for the total score of Y-FBIS was 0.849 at 95% confidence interval. Test-retest reliability of individual scales ranged from 0.780 to 0.874 and was 0.830 for total objective scale score. Convergent validity was shown by the significant positive correlation (r = 0.83) between the objective burden score and subjective burden score of Y-FBIS. ROC curve area was 0.981. Conclusion. The Y-FBIS is a valid, reliable, and sensitive instrument for assessing the burden on caregivers of persons with schizophrenia in Nigeria.

Prevalence of depression in tuberculosis patients in comparison with non-tuberculosis family contacts visiting the DOTS clinic in a Nigerian tertiary care hospital and its correlation with disease pattern.

Background Individuals with chronic diseases such as tuberculosis often have comorbid de-pression that requires frequent hospitalisations. This poses great challenges to the care of such patients.Objective This study aimed at determining the prevalence of depression in tuberculosis patients in comparison with non-tuberculosis controls, and its correlation with disease pattern.Method Eighty-eight patients with tuberculosis and 81 family members visiting the DOTS Centre at University College Hospital Ibadan Centre were screened for depression. Severity of depression was assessed using the Hamilton Depression Scale and was compared with severity of pulmonary tuberculosis.Results The prevalence of depression was 45.5% among patients and 13.4% among family members. Depression was more prevalent among patients that were elderly (P = 0.001), with extensive disease (P = 0.01), of long duration (P = 0.03), those with category 2 tuberculosis (P = 0.003), those from a nuclear family (P = 0.01) and patients that were unmarried (P = 0.02).Conclusion The impact of chronic diseases such as tuberculosis extends beyond physical impairment. It includes behavioural consequences, in this instance depression, for both the patient and the primary care givers. Thus, the care of patients with tuberculosis should be comprehensive and include consultative-liaison psychiatric care.
