Eating disorders (EDs) are found to have high rates of comorbidity accompanied by other mental illnesses in particular with Major Depressive Disorder (MDD). The main objective of the present study was, to conduct a systematic review on the risk of depression in patients suffering from eating disorders (anorexia nervosa, bulimia nervosa). The study was conducted using online databases: such as PUBMED, PsycInfo, ScienceDirect and Google Scholar. Data are collected from studies conducted from 2000 to 2018. Of the selected studies, 6 were case-control studies, 6 were cross-sectional studies, 2 systematic reviews, and only one case study. Out of the 15 selected studies, the majority of them indicated that there is no correlation between eating disorders and depression. This systematic review demonstrates that there is no authenticated scale to evaluate the specific relationship between an eating disorder and different types of depression. There is however a scale that evaluates the relationship between depressive and eating behavior, the Emotional Eating Scale (EES). Based on the results obtained from the majority of the selected studies, it is evident that there is no connection between eating disorders and depression. Usually, symptoms pertaining to depression and eating disorders are comorbid. Hence considering the same view, depressive symptoms are frequently evaluated in regards to an eating disorder. Therefore, additional efforts are needed to extend interventions that are simpler and applicable in diminishing both major depression and eating disorder in order to increase the efficiency of therapy.

This study empirically explored the impact of monetary policy instruments on economic growth in Nigeria from the period 1986 to 2018. Autoregressive distributed lag model (ARDL) was employed for the long run and short run dynamic relationship between each of the policy variables; Money supply, Interest rate and Exchange rate, and the target variable; Gross domestic product. The estimated long run model shows that log of money supply has a positive impact on the log of GDP, Exchange rate in its current period is inversely related to the target variable, while its one period lag positively impacts the target variable. Also, the Interest rate in its current value exerts a positive and significant impact on economic growth in Nigeria. Similarly, in the short run, one period lag of the target positively impacts its current value, while the Exchange rate in its current and one period lag, significantly, exerts a negative and positive impact on economic growth respectively. The error correction mechanism coefficient shows that the speed of adjustment of the variables to equilibrium in the short run is 19%. Therefore, the study concludes that monetary policy instruments are significant in explaining economic growth in Nigeria. Also, it is recommended that necessary measures should be taken by the monetary authority to ensure proper use of the instruments by maintaining favorable interest rate, exchange rate and money supply in to attain the desired level of growth in the economy.
