Special attention should be paid to patients with these factors while designing programmes to improve overall compliance in patients with schizophrenia.

Objective The objective of this study is to compare the prevalence of depression in postpartum women and that of non-postpartum women. Method A total of 876 women recruited at 6 weeks postpartum and 900 matched non-postpartum women were administered the Beck's Depressive Inventory (BDI) and translated local version of the EPDS. Psychiatric diagnosis was made using the using the modified non-patient version of Structured Clinical Interview for DSM-III-R (SCID-NP). Results Depressive disorder was diagnosed in 128 (14.6%) of the postpartum women and in 55 (6.3%) of the non-postpartum women, and the difference was found to be significant (t=8.919, df=875, P<0.001). The postpartum women had higher EPDS and BDI scores than the non-postpartum women. The EPDS correlated well with the SCID-NP diagnosis with a Spearman's correlation of 0.600 (P<0.001) and with the BDI score with a Spearman's correlation of 0.461 (P<0.001). The sensitivity of the EPDS at cut-off score of 8/9 was 94% and specificity was 97%. Conclusion The prevalence of postnatal depression in Nigeria is comparable to that of the western world and the Yoruba version of EPDS is a valid instrument for screening postnatal women for depressive disorders in a Nigerian community.

The objectives of this study were to determine the prevalence and pattern of Kola nut use among secondary school students in Osogbo, Osun State, Nigeria. The study also aimed to determine the association of socio-demographic variables (of the students and their parents) with kola nut chewing. A questionnaire consisting of socio-demographic variables, the stimulant use section of the WHO Students Drug Use Questionnaire was administered on three hundred and eighty-five (385) randomly selected students of the two Local Government Areas of Osogbo. The prevalence rate of kola nut use was calculated and some socio demographic variables were determined. The 30-day prevalence rate of kola nut use was 11.2%. The one-year prevalence of kola nut use was 29.1 percent and the lifetime rate was 74.8 percent. Majority of users started at age 14 years or below. Kola nut use was associated with lower age group, poor school attendance, polygamous background, low education of mother, high education of father and the description of mother as being too permissive. The findings suggest the need to increase the awareness of the dangers of kolanut use among adolescents. Control program are urgently needed to prevent student wastage.
