Economic Recessions in Nigeria: An Econometric Investigation of Roles of Crude oil Price Volatility (1970 -2016)

This paper analysed the relationship between crude oil price volatility and Nigerian• Gross Domestic Products (proxy for growth of Nigerian economy) for the period 1970 to 2016 with Gareh (1, I) model and Vector autoregressive (VAR) model. The result of Arch test confirmed that crude oil price is significantly volatile while analysis of the result of trend of crude oil price volatility from 1970 to 2016 revealed that the 1973-74, 1979-80, 2003-2007, 2010-2014 boom periods were associated with crude oil price increases while the oil price collapse of 1986-2000 and near recession indices of year 2015-2016 is an episode of crude oil price fall.The resultofVARestimation revealed that there is a statistically significant, direct relationship between crude oil price volatility (COP) and gross domestic product (GDP} in the short run. Also, impulse response function showed that shock in crude oil prices has both positive and negative effect on gross domestic product in the short~ depending on whether the shock from crude oil price is an increase or a decrease (positive or negative) which might implied period of economic recession or prosperity. The paper therefore recommended that governments at all levels should intensify their efforts in diversifying the economy to a more productive and less volatile sector like agriculture in order to improve agricultural products export instead of total and heavy reliance on rents from crude oil export whose price is highly volatile and to insulate the economy against these shocks (decrease in oil prices) and its attendant consequences

Prevalence and predictors of exclusive breastfeeding among mothers in a semi-urban Nigerian community: A cross-sectional study

Background: The uptake of exclusive breastfeeding (EBF) is low globally including Nigeria despite its benefits and interventions. This study aimed to assess the prevalence and predictors of EBF among mothers in a semiurban Nigerian community. Methods: We conducted a cross-sectional study among nursing mothers attending the immunization clinic at the Federal Medical Centre, Owo, Ondo State. A semi-structured questionnaire containing the World Health Organization’s indicators for assessing breastfeeding practices was used for data collection. Results: A total of 386 mothers were recruited with a mean age of 30.8 ± 5.0 years. Among them, 149 (36.8%) were below 30 years, 345 (89.4%) have had ANC visit at least four times, and 259 (67.1%) had initiated breastfeeding immediately after delivery. The prevalence of EBF was 52.6%. Natural feeds were the common feeds introduced after 6 months among 159 (78.3%) mothers. One hundred and forty-four  (62.1%) nursing mothers aged 30 years or older practiced EBF compared to 72 (48.3%) persons below 30  years (X2 = 6.290, p = 0.012). Also, 38 (70.3%) mothers who have delivered four or more children practiced  EBF compared to 180 (54.2%) with fewer children (X2 = 5.437, p = 0.020). Nursing mothers aged  30 years or older had 36% higher odds of practicing EBF compared to younger persons (Adjusted  Odds Ratio = 1.358, 95%CI = 0.886 – 2.081, p = 0.160). Conclusion: To achieve the WHO recommended target of ensuring that 90% of nursing mothers practice EBF, advocacy and health education must be intensified
