ABSTRACT ABSTRACT


Globally, substance abuse is a cause of increased concern among youths. Studies
conducted have associated consumption of alcohol as a major contributory factor to
manifest and latent violence, crime, and bodily injuries, as well as to other economic, social, in addition to the academic failures. This cross-sectional epidemiological study was conducted between May 2021 to May 2023 to investigate the prevalence of hypertension and hot beverage intake among the Polytechnic Students in Ogun state
Southwest Nigeria. Two thousand respondents were randomly selected and
examined to determine their socio-economic characteristics and beverage
consumption level. A structured pre validated interview guide and Nigeria Beverage Consumption Survey questionnaires were used to determine the beverage intake of the respondents. Data were analyzed using Statistical Package for Social Science version 21. Pearson Correlation was used to determine the P values of the variables. The results of socio demographic characteristics showed that ninety percentage (90%) of respondents were between the age range of 18-44years in was in majority, fifty two percent (52%) were male while forty eight percent (48%) were female, About eighty seven percent (87%) were single while thirteen percent (3%) were married. Beverage
consumption result showed that Seven percent (7.4%) took 30ml of fresh fruit juices, two percent (2%) took 600ml of fresh fruit juices, eight percent (8%) took 850ml of fresh fruit juices, one percent (1.4%) took 1000ml of fresh fruit juices, two percent (2%) took 3000ml of bottled fruit juices(without sugar), Two percent (2%) took 850ml of bottled fruit juices(with sugar), two percent (2%) while took 120ml of non-alcoholic wine. There is a significant positive relationship between the beverage intake of the respondents (p<0.05). The study showed that the students were not strong drinkers of beverages including water intake (p>0.05). There is a need for proper education to the students on the need to stay hydrated to avoid health issues that can arise because
of dehydration.

ABSTRACT ABSTRACT


The study aimed at optimizing the yield of extraction of flavonoids and phenolics in
Ipomoea batatas leaves as a function of drying temperature (65-105 ºC) and ethanol
concentration (60-80 v/v %) at constant drying time (95 minutes) using Response
Surface Methodology (RSM). From the results, quadratic term was significant for
phenolic content, while 2F1 model was significant for flavonoid content. The
coefficients of determination (R2
) and for phenolic and flavonoid contents were 0.9362 and 0.8102 respectively, showing a good fit model. The model terms were significant (P<0.05) for all the responses which provided its suitability for prediction purposes. The coefficients of variation (CV) for phenolic and flavonoid were 3.21 and 4.21, respectively, both of which were less than 10%. Using desirability function, the optimum operating conditions to obtain higher extraction of phenolic and flavonoid
was found to be 65 °C and 70.33 (v/v %) ethanol concentration. The study implies that Ipomoea batatas leaves possess robust antioxidant abilities making them suitable for therapeutic purposes.
