RESUMO
Background: The use of modern contraceptives has been embraced by developed nations as a means of achieving controlled growth rate. Nigeria, Africa's most populous nation at 158 million with a growth rate of 2% is expected to grow to 730 million by the end of this century. There is need for regular assessment of the knowledge and practice of contraception among women of childbearing age. Aim: The aim of this study is to determine the contraceptiveseeking pattern among women attending antenatal care in an urban city in a developing country and the factors affecting usage. Subjects and Methods: This was a cross-sectional study of 430 antenatal women using structured self-administered questionnaires on randomly selected attendees who consented to participate. Results were analyzed using SPSS Version 16 (Chicago, IL, USA). Results: Although majority of the women 71.2% (306/430) wished to have between 1 and 4 children, only 20% (87/430) had on their own sought for advice on contraception from a health facility. The percentage of women who had a knowledge of contraception was 61.4% (264/430) with highest source of information from antenatal clinics. Among the women, 41.2% (177/430) have used contraception since getting married; 16.1% (69/430) used natural and withdrawal methods while only 25.1% (108/430) used modern contraceptives. Reasons for nonusage of some modern contraceptives given by 340 women include fear of side effect 53.2% (181/340), objection from partner 7.9% (27/340), conflict with religious beliefs 4.1% (14/340) while 34.4% (117/340) had no reason for not using contraceptive. Conclusion: Contraceptive-seeking is low. Programs aimed at encouraging women to deliver in health facilities should be intensified. Health workers should utilize every opportunity to educate on contraceptive choices

Background & objectives: The study examined the mosquito-repellent and mosquitocidal activities of the volatile oil of Ocimum gratissimum at three different locations (World Bank Estate, Ihitte and Umuekunne) in Imo State, eastern Nigeria, with the purpose of sourcing for mosquito repellent that is cheap, abundant, environment and user-friendly. Methods: Four different lotions; 20% (v/v) and 30% (v/v) concentrations each of the extracted volatile oil in two natural oil bases (olive and palm kernel) were made and six volunteered human baits were used to evaluate the mosquito repellent and mosquitocidal activities of the stock materials at the three different centres from September to November 2008. Results: Topical application of each of the four different lotions significantly (p <0.05) reduced the biting rate of mosquitoes in all the three locations tested. The 30% (v/v) concentration in olive oil base exhibiting highest average percentage repellencies of 97.2, 95.7 and 96.3% at World Bank Estate, Ihitte and Umuekunne centres respectively while the 20% (v/v) concentration in palm kernel oil base had the least repellency of 36.3, 41.6 and 36.3%, respectively. The other two formulations had values ranging from 67.8 to 80% in the three locations. The 30% (v/v) concentration in both olive and palm kernel oil bases afforded all night protection against mosquito bites in all the centres, and demonstrated fast knockdown and paralyzing effect on few mosquitoes at the urban centre (World Bank Estate). Interpretation & conclusion: The study confirms that O. gratissimum grown in eastern Nigeria has mosquito-repellent and mosquitocidal potentials and the formulations could be used to reduce human-mosquito contacts and hence mosquito-borne diseases and irritations caused by their bites.
