--- abstract: 'The menarchial age of 859 secondary school girls consisting of 508 from urban and 351 from rural area of Rivers State, Nigeria were determined, using questionnaires and interview method. Data collation revealed that 69.2% (243) of the rural population were menstruating, while 70.1% (356) of the urban population were menstruating. Mean ages of menarche were 13.19±1.32 years and 14.22±1.47 years for urban and rural areas respectively .A statistically significant lower mean menarchial age was observed in urban area girls, compared to their rural counterparts. Girls from families of high socio-economic class has significantly lower mean menarchial age in both urban and rural area. The mean age of menarche was significantly higher in girls involved in vigorous sporting activity in rural areas compared to their non-sporting counterparts. Urban school girls attain menarche earlier than those in rural area. High socio-economic class and vigorous sporting activity can be predisposing factors to low and high age of menarche respectively. There is need for redefinition of high socio-economic class in Nigeria.' altloc: - http://www.ojhas.org/issue14/2005-2-4.htm chapter: ~ commentary: ~ commref: ~ confdates: ~ conference: ~ confloc: ~ contact_email: ~ creators_id: - Ikaraoha CI - Mbadiwe IC - Igwe CU - Allagua DO - Mezie O - Iwo GTO - Ofori PI creators_name: - family: Chidiebere given: Ikaraoha honourific: '' lineage: Ikechukwu - family: Ikaraoha given: Mbadiwe honourific: '' lineage: Chigaekwu - family: Chidi given: Igwe honourific: '' lineage: Uzoma - family: Dennis given: Allagua honourific: '' lineage: O - family: Okoye given: Mezie honourific: '' lineage: '' - family: Golden given: Iwo honourific: '' lineage: TO - family: Peace given: Ofori honourific: '' lineage: I date: 2005-08 date_type: published datestamp: 2005-10-20 department: ~ dir: disk0/00/00/45/54 edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: - Kakkilaya BS editors_name: - family: Kakkilaya given: Srinivas honourific: Dr. lineage: Bevinje eprint_status: archive eprintid: 4554 fileinfo: /style/images/fileicons/application_pdf.png;/4554/1/2005%2D2%2D4.pdf full_text_status: public importid: ~ institution: ~ isbn: ~ ispublished: pub issn: ~ item_issues_comment: [] item_issues_count: 0 item_issues_description: [] item_issues_id: [] item_issues_reported_by: [] item_issues_resolved_by: [] item_issues_status: [] item_issues_timestamp: [] item_issues_type: [] keywords: 'Menarchial age, School Girls, Urban, Rural, Sports, Socio-economic class' lastmod: 2011-03-11 08:56:11 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: 2 pagerange: ~ pubdom: TRUE publication: Online Journal Of Health And Allied Sciences publisher: Dr. B.S.
