Energy drink: the consumption prevalence, and awareness of its potential health implications among commercial drivers in the Ho municipality of Ghana.

BACKGROUND: Consumption of energy drinks has become an escalating global public health problem. The work schedule and irregular sleeping habits of commercial bus drivers make them highly susceptible to getting fatigued, hence most of them consume energy drinks as a fatigue management strategy. However, consumption of energy drinks produces numerous psychomotor side effects that if consumed among drivers puts the traveling public in danger of road accidents. This study sought to assess the prevalence of energy drink consumption and awareness of associated potential health problems among commercial long-distance bus drivers operating from the Ho municipality. METHODS: The study population comprised about 266 commercial bus drivers. This was a cross-sectional study involving 132 participants who completed a structured questionnaire on the participants' socio-demographic characteristics, frequency of consumption and reasons for consumption. It also included questions to assess the knowledge of the ingredients and side effects of energy drinks. Respondents were selected using a convenience sampling technique. Descriptive analysis and Chi-square test of association were used to analyse the data. RESULTS: A majority (62.1%) of the drivers had more than 10 years of commercial driving experience. A 75% energy drink consumption prevalence was recorded with driving performance enhancement (78.8%) as the predominant reason for consumption. 7-10 bottles per week were consumed by most (32.2%) of the drivers. Also, 72.0% had poor knowledge of the side effects linked with energy drink consumption as well as the ingredients for preparation. CONCLUSION: Energy drinks were consumed by the majority of the drivers at the Ho main bus terminal of which most of the drivers had poor knowledge of the potential health problems linked with the consumption of these drinks. The consumption of energy drinks was observed to be higher among the drivers with lower education levels, higher monthly income and those who worked long hours in a day. The Ghana National Road Safety Commission (GNRC) in collaboration with other private road transport unions in Ghana should organize regular seminars for commercial bus drivers on the potential dangers and effects associated with energy drink consumption.

Health risk assessment and levels of toxic metals in fishes (Oreochromis noliticus and Clarias anguillaris) from Ankobrah and Pra basins: Impact of illegal mining activities on food safety.

Arsenic (As), mercury (Hg), Cadmium (Cd) and lead (Pb) are toxic heavy metals that naturally occur in the ecosystem. Their levels are on the rise due to anthropogenic activities posing threat to aquatic wildlife and humans. In Ghana, pollution of some water bodies has led to unsafe consumption of riverine fishes as well as a shortage of treated potable water principally because the cost of treating polluted water has become expensive across the country. This study aimed to assess the As, Hg, Pb and Cd concentrations in water and fishes from rivers Pra and Ankobrah where activities of artisanal gold mining were carried out resulting in gross pollution of the water bodies. An experimental study was performed to ascertain the levels of As, Hg, Pb and Cd in fish species of Nile tilapia (Oreochromis noliticus) and mudfish (Clarias anguillaris) and aquatic media (water) from the Pra and River Ankobrah basins using the Atomic Absorption Spectrophotometer (AAS) (Varian AA240FS). Both river water samples recorded ranges of 0- 0.0040, 0.0060- 0.0387, 0 - 0.0020, 0.006-0.0093 mg/l for Cadmium, Lead, Arsenic and Mercury respectively. For Cadmium and Arsenic, their levels were comparable (p > 0.05). However, detected values for Lead and Mercury were no comparable (p < 0.05). Toxic metals concentrations in the rivers decreased in the order of Hg > Pb > Cd > As. For the fish samples, values ranged 0-0.08, 0.04-0.42, 0-0.04, and 0.40- 0.60 mg/kg for Cadmium, Lead, Arsenic and Mercury respectively. Generally, appreciably high values were obtained for Mercury. Toxic metals concentrations in the rivers decreased in the order of Hg > Pb > Cd > As. Human health risk assessment from heavy metal exposure through fish consumption from the Rivers for both children and adults showed no significant non-carcinogenic adverse health risk to humans since all calculated values for Hazard Quotient (HQ) were <1. Nonetheless, Target Hazard Quotient (THQ) values calculated for children and adult exposure to Cadmium and Mercury were>1 which implied a likely cause of adverse effects during a person's lifetime.
