BACKGROUND: Schizophrenia is highly disabling. Though efforts at genetic mapping to identify those at risk of the illness have been promising but same cannot be said about predicting its associated disability before illness-onset (i.e., during premorbid phase). It is envisaged that Schizophrenia-related disability may be ameliorated if premorbid clinical markers are adequately predictive enough to identify those at risk and worked upon them. AIM: This study aimed to determine whether there is a relationship between schizophrenia-related disability and premorbid adjustment. SETTING: This cross-sectional study was conducted at the out-patient clinic of the Neuropsychiatric Hospital, Aro, Abeokuta, Ogun State, Nigeria. METHODS: Three hundred patients with the diagnosis of schizophrenia and within the age range of 18-64 years were eligible for the study. RESULTS: Mean age of the participants was 41.9 ± 10.05 years with a slight female dominance (50.7%). Spearman's correlation revealed a direct correlation between disability and premorbid adjustment, albeit rather weak (r s = 0.130, p = 0.025). CONCLUSION: Pre-diagnostic factors such as premorbid functioning may play a role in the subsequent functioning of an individual post-diagnosis. Other research efforts may focus on yet-to-be identified premorbid factors that may be targets of prevention to reduce disability in schizophrenia. CONTRIBUTION: This research serves as a pioneer work on disability and premorbid adjustment and has provided a template for the early identification of those at risk of schizophrenia by providing an intervention opportunity at the premorbid stage

BACKGROUND: Studies from developed countries have shown that poor premorbid adjustment in patients with schizophrenia is associated with poor outcome. However, similar studies in developing countries like Nigeria are few despite the stability of schizophrenia prevalence across cultures. AIM: The aim of this study was to assess the prevalence and correlates of poor premorbid adjustment amongst outpatients with schizophrenia. SETTING: The Neuropsychiatric Hospital, Abeokuta in Ogun State, Nigeria. METHODS: The premorbid adjustment of 300 outpatients with schizophrenia was assessed using the premorbid adjustment scale. Pattern and severity of psychosis, overall illness severity, global assessment of functioning and socio-demographic factors were investigated as correlates of premorbid functioning. RESULTS: About half (53.3%) of the respondents had poor premorbid adjustment and most of them were males (56.9%). Poor premorbid adjustment was associated with male gender (χ² = 7.81, p = 0.005) whilst good premorbid adjustment was associated with no or borderline illness severity (χ² = 8.26, p = 0.016) as well as no or mild impairment in functioning (χ² = 7.01, p = 0.029) amongst the respondents. Positive, negative and general symptomatology were predicted by premorbid adjustment at different developmental stages CONCLUSION: Consistent with existing literature, poor premorbid adjustment was prevalent amongst patients with schizophrenia in this study and was associated with male gender, poorer clinical outcomes and greater illness severity. Mental health promotion and other preventative approaches are recommended as possible early intervention strategies in dealing with schizophrenia.

BACKGROUND: Despite several studies on the prevalence and pattern of substance use in Nigeria, there is little information on substance use in patients diagnosed with serious mental illness (SMI) such as schizophrenia and bipolar affective disorder (BD). AIM: The aim of the study was to compare the pattern of psychoactive substance use among outpatients with BD and schizophrenia. SETTING: The study was conducted in a neuropsychiatric hospital in Nigeria. METHODS: Seventy five consecutive patients with a MINI-PLUS diagnosis of BD were compared with an equal number of patients obtained by systematic random sampling with a MINI-PLUS diagnosis of schizophrenia. RESULTS: The respondents with schizophrenia were aged 18-59 years (37.2 ± 9.99) and were predominantly young adult (49, 65.3%), men (46, 61.3%), who were never married (38, 50.7%). Overall, lifetime drug use prevalence was 52%, while for current use, overall prevalence was 21.3%. Participants with BD were aged 18-63 years (36.7 ± 10.29) and were predominantly young adult (53, 70.7%), women (44, 58.7%), who were married (32, 42.7%), with tertiary education (31, 41.3%). Overall, lifetime drug use prevalence was 46.7%, while current overall prevalence was 17.3%. These rates (lifetime and current) for both diagnostic groups are higher than what was reported by the World Health Organization in the global status report of 2014 (0% - 16%). The statistically significant difference between the two diagnostic groups was related to their sociodemographic and clinical variables and psychoactive substance use. CONCLUSION: Psychoactive substance use remains a burden in the care of patients diagnosed with schizophrenia and BD. Future policies should incorporate routine screening for substance use at the outpatient department with a view to stemming the tide of this menace.

Apneia obstrutiva do sono (SAOS) é uma condição médica com consequências adversas. OBJETIVOS: Descrever os fatores de risco associados com OSA em adultos atendidos em uma clínica especializada ambulatorial. Forma de estudo: Estudo clínico prospectivo, entre pacientes ambulatoriais adultos em uma clínica especializada. MÉTODO: Os dados foram coletados por meio de questionário incorporando o BQ e os pacientes foram divididos em riscos de baixa e alta da OSA. Os fatores de risco associados com OSA na análise univariada foram submetidas a um modelo multivariado de regressão logística binária. Odds ratio ajustados com intervalo de confiança de 95% foram calculados para as seguintes variáveis independentes. RESULTADOS: Cento e nove e cinco pacientes participaram do estudo (sexo masculino 56,4%; idade 43,5 ± 15,6 anos; não roncadores habituais 81,5%, risco de alta OSA 17,4%, IMC 24,1 ± 4,6 kg/m²; obesos 12,9%). Seis fatores, incluindo o estado civil e a pressão arterial, foram significativamente associados com SAOS usando análise bivariada, no entanto, idade, horas de trabalho, tabagismo e IMC permaneceu preditivo da OSA na análise de regressão logística. CONCLUSÕES: SAOS é comum entre pacientes nigerianos, pode ser sub-reconhecida e está associada a fatores de risco que são passíveis de estratégias preventivas.

Obstructive sleep apnea (OSA) is a medical condition with adverse consequences. OSA is credited to be a sleep disorder that disproportionately affects blacks. The Berlin Questionnaire (BQ) is a screening questionnaire for OSA. OBJECTIVE: To describe the risk factors associated with OSA among adults attending an out-patient specialist clinic. Study design: Prospective, clinical study including adult outpatients attending a specialist clinic. METHOD: Data was collected using a questionnaire incorporating the BQ and patients were divided into low and high risks of OSA. The risk factors associated with OSA in the univariate analyses were subjected to a multivariate binary logistic regression model. Adjusted odds ratios with 95% confidence intervals were calculated for these independent variables. RESULTS: One hundred and ninety five patients participated in the study (Males 56.4%; Age 43.5 ± 15.6 years; Non-habitual snorers 81.5%; High risk OSA 17.4%; BMI 24.1 ± 4.6 kg/m²; Obese 12.9%). Six factors including marital status and blood pressure were significantly associated with OSA using bivariate analysis nevertheless age, hours at work, smoking status and BMI remained predictive of OSA on logistic regression analysis. CONCLUSIONS: OSA is common among Nigerian outpatients, may be under-recognized and is associated with risk factors that are amenable to preventive strategies.
