Energy drinks are non alcoholic, carbonated beverages claimed to give extra burst of energy for daily obligation. They contain some form of legal stimulants and vitamins which are meant to give consumers short term boost in energy and increase mental alertness. Energy drinks enjoy patronage especially among higher institution students in Nigeria, but little is known about the consumption pattern and possible health risks to consumers. This study was carried out to determine the contribution of four commonly consumed energy drinks to energy intake of University of Ibadan students and the associated health risk factors. A descriptive cross-sectional survey of energy drinks consumption was carried out using a four-stage systematic random sampling technique to select 307 students from six out of nine halls of residence for Undergraduates and the two Postgraduate halls. A validated semi-structured, self-administered questionnaire was used to collect information on socio-demographic characteristics, consumption pattern and frequency, and factors influencing consumption of energy drinks. Samples of the four most commonly consumed energy drinks by the students (Power Horse, Emerge, Red Bull and Matador brands) were purchased from different stores within and around the University of Ibadan campus. Composite samples of all the four energy drinks (with at least six months expiration date) were analysed for physico- chemical characteristics, gross energy, minerals and B-vitamins content in triplicate using standard methods of AOAC. Data were analysed using descriptive statistics and one way ANOVA, and level of significance set at p < 0.05. Respondents mean age was 23.1 ± 4.6 years, 79.2% were undergraduates and 51.1% were female. Majority (74.6%) of respondents had ever taken energy drinks prior to the study, 42.4% reported consuming at least one can in a week, and 52.1% consumed 1 can at a sitting. Reasons for consumption included to increase: energy (48.2%), mental alertness (18.6%) and athletic performance (9.5%). Reported side effects were: insomnia (14.0%), frequent urination (12.2%), dehydration (11.3%), anxiety (9.1%), heart palpitation (3.5%). Frequency of consumption was significantly associated with gender (p < 0.05). Titratable acidity, total solids and pH of energy drinks ranged between 7.57 ± 0.60 - 8.28 ± 0.08, 7.57 ± 0.60 - 11.42 ± 0.31, and 3.36 ± 0.08 - 3.81 ± 0.12 respectively. Glucose, sucrose, and gross energy content ranged between 7.77 ± 0.01 - 7.89 ± 0.01 g, 22.61 ± 0.07 - 23.74 ± 0.09 g, and 43.59 ± 0.38 - 48.89 ± 0.28 kcal/100g respectively. Few respondents knew about the ingredients and potential health risks associated with energy drink consumption. All the four drinks had acidic pH, hence nutrition education on reduction of energy drink consumption is needed among these students.

Does Immigration Promote the Investment of the Monopolistic Firm?

In the present paper, we examine the effect of increasing uncertainty of immigrants’ growth on the optimal timing of investment of a firm that has a monopolistic power over the labor market. It is revealed that when the uncertainty of immigrants’ growth is more than a threshold level, increasing uncertainty of immigrants’ growth accelerates the optimal timing of firms’ investment and enhances the economic growth, even if the uncertainty of immigrants’ growth is formulated by the geometric Brownian motion, which is in sharp contrast to the standard result that an increase in the uncertainty postpones the optimal timing. With an increase in the immigrants over the past ten years, workforces in the host countries have been growing significantly to the extent that the immigrants represent 70% of the increase in the workforce in Europe, and 47% in the United States as OECD indicates. In the present paper, we attempted to investigate the effect of increased uncertainty caused by the growi...

Education Policy Implementation: A Mechanism for Enhancing Primary Education Development in Zanzibar

Education is one of the fundamental rights of individuals; therefore, the government of a country needs to develop and strengthen educational policy and quality as well as to ensure that everyone has equal access to basic education. The improvement of access and quality of education in the world is becoming as an essential factor in development, whereas the basic education (primary school), is acknowledged as a foundation of the higher educational development for every country. To fulfill this goal, governments introduce several policies and procedures; however, it requires some reforms and participation from the politician, policymakers, and other stakeholders to re-examine educational policy so that it can lead to multiplication and betterment of the reforms. Educational reforms actually focus on accountability. A positive educational development and reform is very challenging and needs more effort and strategy on how to use and utilize the resources effectively as such it can achie...
