ABSTRACT This study aimed to determine the prevalence of ADHD and co-morbid conditions in a sample of primary school children aged 7-12 years in Nigeria.
A two-staged procedure in which primary school pupils aged 6-12 years (n = 1112) were assessed for DSM-IV criteria of attention deficit hyperactivity disorder (ADHD) by their teachers in the first stage and their parents in the second stage. A flexible criterion was used for estimating the prevalence.
The prevalence of ADHD was 8.7%. The prevalence of the subtypes were: predominantly Inattentive 4.9%, predominantly hyperactive/impulsive 1.2% and combined 2.6%. The male to female ratio was 2:1 for all the subtypes of ADHD except hyperactive/impulsive which was 3.2:1. The co-morbid conditions include oppositional defiant disorder (ODD - 25.8%), conduct disorder (CD - 9.3%) and anxiety/depression (20.6%). While ODD and CD were associated with the hyperactive/impulsive subtype, anxiety/depression was associated with inattentive subtype.
Our findings support the notion that ADHD occurs across cultures. Given the prevalent rate, efforts should be made to map out strategies for early identification and referral of these children for proper evaluation and treatment. This study can serve as a platform for future analytical studies about this challenging research issue in sub-Saharan Africa.

    ABSTRACT: 5 ÖZET: Trabzon ili ilkö¤retim ça¤› çocuklar›nda dikkat eksiklii hiperaktivite bozukluu ve efllik eden y›k›c› davran›fl bozukluklar› yayg›nl›¤› Amaç: Bu çal›flman›n amac› Trabzon ilinde ilkö¤retim ça¤› çocuklar›nda Dikkat Eksiklii Hiperaktivite Bozukluu'nun (DEHB) ve ona efllik eden Y›k›c› Davran›fl Bozukluklar›'n›n (YDB) yayg›nl›¤›n› incelemektir. Yöntem: Çal›flmada 6-12 yafl aral›¤›ndaki ilkokul ö¤rencile- rinde (n=1126) DSM-IV tan› ölçütlerine göre DEHB ve YDB tan›lar›n›n konulmas› amac› ile Turgay'›n Çocuk ve Ergen- lerde Davran›m Bozukluklar› için DSM-IV'e Dayal› Tarama Ölçei kullan›lm›flt›r. Bulgular: DEHB yayg›nl›¤› %8.6 (n=97) ve alt tip da¤›l›mla- r› dikkat eksiklii %1.6 (n=18), hiperaktif/ dürtüsel tip %6 (n=69) ve kombine %0.9 (n=10) olarak s›ralanm›flt›r. Erkek k›z oran› DEHB'nin tüm alt tipleri için 3.5/1 olarak bulun- mufltur. Örneklemde dier YDB yayg›nl›¤› %18.6 (n=209)'d›r. Karfl›t Gelme-Karfl› Olma Bozukluu'nun (KG-KOB) yayg›nl›¤› %14.1 (n=159) ve Davran›m Bozuklu- ¤u'nunki (DB) %4.4 (n=50) olarak belirlenmifltir. DEHB olan olgularda KG-KOB'nin s›kl›¤› %57.5 (n=56)ve DB'nin s›kl›¤› %20.6 (n=20)'d›r. Sonuç: Bu çal›flman›n sonuçlar› DEHB yayg›nl›¤›n›n, erkek bask›nl›¤›n›n ve efllik eden YDB s›kl›¤›n›n kültürler aras›nda anlaml› bir farkl›l›k göstermedii görüflünü desteklemekte- dir. Öte yandan hiperaktif/ dürtüsel alt tipin da¤›l›m› litera- türde sunulan oranlardan farkl›l›k göstermektedir. Bu fark›n Türk toplumunda çocua yönelik yafla bal› tutumlar, yak- lafl›m örüntüleri ve beklentilerle iliflkili kültürel farklarla fle- killlenebilecei deerlendirilmifltir. Bu noktan›n kültürel farklara odaklanan ileri çal›flmalarla aç›klanmas› önerilmek- tedir.

    ABSTRACT: The paper deals with ceria–zirconia supported copper catalysts in NO reduction by toluene. Catalysts were characterized by XRD and H2-TPR. The deNOx temperature window was estimated by NO-TPD experiments which revealed two NO desorption areas. The activity and temperature range for deNOx reaction were being observed during temperature programmed deNOx reaction (TPSR) in the presence of toluene. NOx decomposition, starting above 200°C, was accompanied by total oxidation of toluene. Catalytic tests performed in stationary conditions revealed that the most active in C7H8-SCR of NOx is Cu(4)/CeZrO2.
