    Survey of pathogenic bacteria in bottom sediments of Iloilo River: An assessment of water sanitary quality
    Araneta, Karla Teresa S.; Bugayong, Adrienne Marrie S.; Cabanilla, Jennifer C.; Caro, Mary Ann Gina C.; Gayatgay, Christian Era U.; Nufuar, Ernest Jan T.; Rufino Krystal Hope S. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2009-03)
    This study assessed the water sanitary quality of the Iloilo River by determining the monthly heterotophic plate count (HPC), total coliform (TC), fecal coliform (FC), and fecal streptococcus (FS) counts of the bottom sediments in five sampling sites from October 2008 to February 2009. These parameters were then correlated with the physico-chemical parameters that were additionally obtained from the river water. The presence of Salmonella spp, E. coli. Vibrio spp, and fecal Streptococcus were also determined as indicators of the pathogenic bacteria in the bottom sediments of the Iloilo River. Using the FC:FS ratio, the study further distinguished fecal contamination sources from each site as human, animal, or mixed in origin. An assessment of sediment quality was done using DENR standards for TC and Kohl and Albinger's sediment quality criteria for HPC and FC. Sediment samples were taken from the following sampling sites along the Iloilo River: 1) Forbes. 2) Dungon, 3) IBRD, 4) Carpenter's, and 5) So-oc. No significant difference in any of the physico-chemical or microbiological parameters were found among sampling stations. However, analysis and comparison of the microbiological parameters of bottom sediments in terms of months showed significant temporal variability HPC, TC, and FC alternately decrease and increase every month while FS showed a generally increasing trend. The following correlations between the microbiological and physico-chemical parameters were found. 1) temperature with HPC and FS , 2) salinity with FS count, and 3) dissolved oxygen concentration with TC and FC Counts. The mean percentage of bottom sediment samples with Salmonella ranged from 3% to 10% while more than half of samples from all sampling sites showed the presence of Vibrio spp. and S. faecalis. Samples with E.coli from all sites ranged from 3 to 14%. Fecal contamination sources varied across sampling sites. So-oc show ed mostly animal sources as its orgin of fecal contamination, while other sites had either animal, human or mixed sources. S. faecalis and E. coli exhibited multiple antibiotic resistance, a grow ing health concent in many of today's rivers. All isolates were susceptible to Gentamicin and Ciprofloxacin but resistant to Penicillin. Based on HPC and FC values the degree of loading with easily decomposable organic substance and feces among the sampling sites ranges from very little to little. TC count of the sediment samples from all the sites does not exceed the limit of 5000 CFU/ 100ml set by the DENR. Results suggest that sediments were not a significant reservoir of bacterial pollution at the time this study was conducted.

    Waist-to-hip ratio, body mass index and hypertension among adult in the San Rafael Catchment Area in Miagao, Iloilo
    Alfabeto, Ace Robert; Anglopez, Mae Therese; Arzaga, Rhodora; Jocsing, Christy Joy; Sandoy, Rovi Floresa; Tan. Louie Lito (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2009-03)
    A cross sectional study was conducted among 169 randomly selected adults of selected barangays served by the San Rafael Health Center in Miagao, Iloilo. The study determined the relationship of anthropometric measures Body Mass Index and Waist to Hip Ratio with hypertension. Several biological and socio-demographic variables including age, physical activity, family history, family income, smoking and alcohol consumption were studied to determine their possible association with hypertension. These were analyzed with binary logistic regression for their possible association with hypertension. The prevalence of hypertension in the San Rafael Catchment Area was found to be 47.3%. This value is greater than the 22% national prevalence obtained in the 6th National Nutrition Survey of Filipino adults in 2003-2004. A higher prevalence of hypertension was found to be higher among males (51.4%) than in females (44.2%). the prevalence of hypertension obtained using BMI as an indicator of overweight and obese individuals was 51.2%. On the other hand, the prevalence of hypertension using WHR as a measure of android obesity was found to be lower (45.6%). Based on analysis with binary logistic regression, none of the confounding factors (sex, age, family history, physical activity, smoking and alcohol consumption) was significantly associated with hypertension. Body Mass Index was used in the study to identify those who were overweight and obese and Waist to Hip ratio to identify those who had android obesity. Based on body mass index, the prevalence of overweight and obesity was found to be 15.38%. The prevalence of android obesity based on Waist to Hip Ratio was found to be 40.24%. Body Mass Index was positively correlated to SBP but not to DBP based on analysis by linear regression. However, low R squared values show that BMI is a poor indicator for hypertension. Likewise, WHR was positively correlated to both SBP and DBP by linear regression, but was also found to be a poor indicator of hypertension. The results obtained recommend further study in the San Rafael Catchment area. The prevalence of hypertension and android obesity are found to be much higher than national statistics. However, no significant relationship between the anthropometric measurements and hypertension could be drawn from the present study.
