Childbearing dynamics among married women of reproductive age in Nigeria: re-affirming the role of education

Nigeria ranks among the high-fertility countries in sub-Saharan Africa. Studies that examine relationship between fertility dynamics and education are important to improving maternal and child health. This study uses 2008 NDHS dataset on births history of married women of childbearing age. Data were analysed using ANOVA, Kaplan-Meier and Cox-proportional hazard models. Mean CEB were 6.72 and 4.31 among women with no formal education and higher education respectively. Majority (38.6%) of the women left 24-35 months births-interval. Women with lower education exhibited shorter births-interval and higher completed fertility than more educated women. The Births Progression Hazard Rate from marriage to 1 birth was higher among highly educated women than those with no education, but reverse pattern was observed at higher order births. This pattern barely changes after controlling for other socio-demographic variables. Education remains an important factor in fertility dynamics in Nigeria; therefore, existing policies addressing female education should be sustained

Determinants of Unmet Need for Modern Contraception and Reasons for Non-use among Married Women in Rural Areas of Burkina Faso

Burkina-Faso (TFR=6.0) is among the top-ten high fertility countries world-wide and CPR (15%) among women is low. This study examined the factors associated with non-use of modern contraception among married women residing in the rural areas of Burkina-Faso. The study used 2010 Burkina Faso Demographic and Health Survey data-set and focussed on married women aged 15-49 years (n=7,191). Chi-square and logistic regression techniques were used for the analysis (a=5%). Mean number of living children was significantly higher among women who have UNMC (3.92) than those with met need (3.01). Modern CPR and UNMC among married women was 12.7% and 40.7% respectively. The multivariate analysis reveals that being married more than once increases the likelihood of UNMC (OR=1.304; C.I=1.0821.571, p<0.05). Husbands’ approval of FP is a protective factor of UNMC (OR=0.858; C.I=0.7560.975, p<0.05). Husbands’ approval and health education on benefits of FP are important factors to consider in strategies aimed at reducing UNMC in Burkina-Faso.

Ethnic disparities in fertility and its determinants in Nigeria

Background High fertility rate has been consistently reported in Nigeria. The three major ethnic groups in Nigeria, Hausa/Fulani, Igbo, and Yoruba have different socio-cultural identities particularly those that relate to fertility but fertility index is often reported at the national level. This paper examined ethnic differences in fertility and identified its determinants in Nigeria. Method This cross-sectional design study focused on 23,140 women aged 15–49 years. Fertility was measured from information on the full birth history of women of reproductive age. Fertility was assessed using descriptive statistics, parity progression ratio(PPR) and negative binomial model (α = 0.05). Results The total fertility rate was 8.02, 4.91 and 4.43 among women in Hausa/Fulani, Igbo and Yoruba ethnic group respectively. The proportion of women with ≥5 children was highest among the Hausa/Fulani (40%), followed by Igbo (21.6%) and Yoruba (17.5%). For women aged 45–49 years; the PPR was highest among Hausa/Fulani while Igbo and Yoruba exhibited a similar pattern. The mean fertility was 1.725(C.I = 1.661–1.792, p < 0.001) times higher among Hausa/Fulani than Yoruba women, but Igbo and Yoruba women exhibited a similar pattern. Controlling for other factors barely changes this pattern. Conclusion Variation existed in fertility across the main ethnic groups in Nigeria, but highest among Hausa/Fulani. Fertility reduction strategies that target improvement in women’s education will reduce the fertility rate in Nigeria, particularly among Hausa/Fulani women. Ethnicity is important in fertility reduction strategies in Nigeria

Mathematical music theory of embodied acoustics of Ikoro music using beat-class theory

Through mathematical representation (beat-class theory) of embodied acoustics (psychoacoustics) the predominance of the musical tradition of the Ikoro drum with the Igbo's can be traced from the past, into the present and forecasted into the future. The Ikoro music tradition has been viewed as an integral and indispensable part of Igbo culture at large (Onwubiko and Neilsen, 2019). The major musical instruments that accompany most Igbo music are percussional, such as, ichaka (beaded-gourd rattle), okpokolo (wooden claves), and igba (membrane drum) and are characterized by successions of rhythmic interchange unlimited to interesting pitch, timbre, rhythm and meter by employing shifted accents, non-accented rhythms and syncopations. In order to understand Ikoro music located in the listener's experience (embodied psychoacoustics), we demonstrate how mathematical music theory (beat-class theory) provides the means to articulate the “mind and body” response to the stimulus of sound. By examining the aural tradition of Ikoro music of the Igbo's through visualizations and sonifications of beat-class theory using ski-hill graphs and circular cyclic graphs, “hidden” musical structures are revealed which possess significant cultural significance

Hydrocarbon-degrading bacteria isolation and surfactant influence on the growth of organisms: A case study in Ibadan, Nigeria

Hydrocarbons are substantially insoluble in water, often remaining partitioned in the non-aqueous phase liquid (NAPL). However, there had been little or no attempts to advance the bioavailability of hydrocarbons through the use of surfactants. This study was conducted based on the need to isolate hydrocarbon degrading bacteria and to establish the effect of surfactants on the growth of organisms. Ten organisms were isolated and classified into five genera based on their physiological, morphological and biochemical characteristics. These genera include Pseudomonas, Bacillus, Micrococcus, Flavobacterium and Corynebacterium. In determining the effect of surfactant on isolated organisms, Bacillus strain and Corynebacterium strains were enhanced by palmitic acid. Detergent was found to have stimulatory effect on Bacillus and Pseudomonas. There is a significant difference between separate applications of palmitic acid and detergent on the samples with respect to the growth of Micrococcus sp. (p &lt; 0.01). There was also a significant difference between the applications of detergent and control on the selected samples with respect to Flavobacterium sp. (p &lt; 0.001). Surfactant which stimulated bacterial growth is highly recommended in bioremediation, although the use of improved strains may be preferable.Keywords: Hydrocarbons, surfactants, biodegradation, pollutants, microoganism

Contraceptive use among Nigerian women with no fertility intention: interaction amid potential causative factors

High fertility (HF) remains a public health problem and intention to reduce fertility is a global phenomenon. The health hazards and economic burden of HF on women are enormous. Contraceptive is widely known as a fertility reduction method. Achieving desirable MDGs and PoA of 1994 ICPD will be an illusion if research on the relationship between fertility intention and contraceptive use is neglected. The study which focused on 2,257 women of childbearing age who do not have any intention to bear more children utilized Nigeria Demographic Health Survey, 2008 dataset. Data was analysed using Chi-square, binary and multinomial logistic regression (=5.0%). Mean age of the women and children ever born were 40.91±5.73 years and 6.28±2.62 respectfully. The prevalence of Current Use of Any Contraceptive Method (CUACM) was 37.6% with 12.4% and 25.2% currently using natural and modern family planning methods respectively. About 7.0% of women in poorest wealth quintile are CUACM compared to 61.8% of those in richest wealth quintile. Current use of modern contraceptive prevalence rate was strikingly higher among Yorubas (41.8%) than the Hausas (3.6%). Multivariate analysis identified age, region, residence, education, ethnicity and family planning media exposure as significant predictors of CUACM. In addition; religion and decision on how to spend family income were identified as predictors of current use of modern contraceptive method (p&lt;0.05). The use of contraceptive is not adequately practiced in Nigeria. The identified predictors of contraceptive use in this study should be considered while designing strategies to improve contraceptive prevalent rate in Nigeria

Factors Influencing Satisfaction with Service Delivery Among National Health Insurance Scheme Enrollees in Ibadan, Southwest Nigeria.

Perceived quality of care is a determinant of uptake of health services. This study aimed to assess the determinants of quality of care of enrollees in the National Health Insurance Scheme (NHIS) in Nigeria. The outcome was satisfaction with health care services, which was used as a proxy for quality. Findings will assist in the intervention to enhance enrollment in the scheme and for universal health coverage attainment. This was a descriptive cross-sectional study conducted among enrollees in selected NHIS facilities in Ibadan, Nigeria. Data on satisfaction with health care were collected among selected 432 enrollees with the aid of an adapted semi-structured WHO-USAID interviewer-administered questionnaire. Data were analyzed using chi-square and multiple logistic regression models (α = 0.05). Among predictors of satisfaction with health services were younger age (OR = 1.85, 95% CI = 1.05-3.25, p = .024), working in the private sector (OR = 1.84, 95% CI = 1.03-3.28, p = .022), and seeking information about quality of services prior enrollment (OR = 1.63, 95% CI = 1.04-2.53, p = .013). Targeted intervention based on the findings of this study should be implemented to improve satisfaction with the services offered

FACTORS INFLUENCING THE CAREER CHOICE OF LIBRARY AND INFORMATION SCIENCE STUDENT’S IN FEDERAL POLYTECHNIC EDE, OSUN STATE

This study investigates the factors influencing the career choice of library and information science students in Federal Polytechnic Ede, Osun State. The major objectives of this study was to find out the factors that influence the choice of librarianship as a career among students, the level of students perception towards library and information science as a career and to find a way out on how library and information science can become a reputable discipline in the society. A total number of 127 newly admitted students into LIS were purposely chosen. Enumerative sampling techniques were adopted. Structured questionnaire were used for data collection. Findings of the study revealed that students were influenced based on their personal interest in the course 78(70.9%), to seek for knowledge 77(70.0%) and Career expectation 60(54.5%). The study also find out that the students level of perception towards choosing librarianship as a career, and it was indicated that Library and information science is a lucrative field 95(86.4%), Library and information science is a professional course 93(84.6%),it offers job security 76(69.1%) and they will like to further their career in librarianship 60(54.5%). Furthermore the study find out that librarianship as a career should be introduced to secondary schools curriculum in Nigeria 99(90.0%).The study therefore recommendthat there should be a continuous awareness of LIS in other to clarify the belief of the public that LIS profession is a dumping ground for poor students, Nigeria library association should be involved in educating the publics about librarianship as a profession through symposiums, conferences, etc

Variations in modern contraceptive uptake and its correlates in South West and North East Nigeria: a comparative analysis

Background: Family planning programs are implemented specifically to address the sexual and reproductive health challenges of women of childbearing age but these interventions are yet to address regional differences in modern contraceptive usage in Nigeria. Hence, this study aimed to examine correlates of modern contraceptive uptake in South West and North Eastern, Nigeria.Methods: A cross-sectional survey data for women aged 15-49 years was extracted from Nigeria demographic and health surveys 2018 (NDHS). Data analyses were based on a weighted sample of 10,907 (North East= 5406 and South West = 5501) women of reproductive age. The outcome variable was modern contraceptive use. The main explanatory variables were age, employment status, religion, Number of living children, education, and marital status. Frequency distribution, Chi-square test, and binary logistic regression were used for data analysis (α=0.05).Results: The result showed the mean age of women of reproductive age in South West and North East to be 32years and 30 years respectively. More women in South West used modern contraceptive than women in North East. About 91.5% and 75.8% of women in North East and South West respectively did not used any modern method. The result showed that, in the South West, number of living children (OR:4.06, CI: 2.794-5.921), education (OR:1.35, CI: 1.045-1.754) and wealth index (OR:1.77, CI: 1.053-2.973) increased the odds of contraceptive uptake, while maternal age (OR:0.52, CI: 0.282-0.965), religion (OR:0.25, CI: 0.184-0.347) and place of residence (OR:0.68, CI: 0.504-0.916) significantly reduced the odds of modern contraceptive uptake in North East.Conclusions: This study concludes that there are regional variations in uptake and predictors of modern contraceptives use in Nigeria. Therefore, sexual and reproductive health interventions that considers the study’s significant variables should be put in place to increase uptake
