Item Prevalence and risk factors for hypertension and obesity among public utility jeepney and tricycle drivers in Janiauy, IloiloBacallan, Jed Vincent; Caro, Miguel Angelo; Delos Reyes, Fate; Divinigracia, Bert Lorenz; Ehimplar, Annie Rose; Lavente, Hannah Gail; Mallorca, Tracy Roz; Tabañar, Jessa Andrea; Tubeo, Nikki Francheska; Villanueva, Ma. Sharee Lou (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2014-04)A cross sectional study was conducted in Janiuay, Iloilo, involving tricycle drivers and jeepney drivers. The objective of this study was to determine and compare the prevalence and risk factors for hypertension and obesity between public utility jeepney and tricycle drivers in Janiuay, Iloilo. A total of 165 respondents, jeepney (87) and tricycle (78), were measured with an aneroid sphygmomanometer and tape measure to determine the blood pressure and waist-hip ratio. An interview was also conducted to determine occupational factors and lifestyle habits. Results were analyzed through SPSS using Chi-square test, T-test and Odds ratio. The prevalence of hypertension was found to be greater in jeepney drivers (36.80%) compared to tricycle drivers (34.60%). The prevalence of obesity was found to be greater in tricycle drivers (46%) compared to jeepney drivers (45%). There is a significant difference in the occupational risk factors between jeepney drivers and tricycle drivers, years of driving, average trip time, kilometers travelled per day and number of trips per day (p<0.0005). However, working days per week (p<0.08) and working hours per day (p<0.30) showed no significant difference between two populations. The results of the odds ratio showed no significant effect in all lifestyle factors to hypertension and obesity. There is no significant difference in the prevalence of hypertension, obesity, and lifestyle risk factors between jeepney drivers and tricycle drivers. However there is a significant difference in the occupational risk factors between the two driver populations.Item Temporal variation in the subtidal macroinfaunal composition of a NaGISA seagrass bed in southern Guimaras, Philippines between 2015 and 2016Bacabac, Earl Jeroh I. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2019-06)Seagrass meadows are amongst the most abundant and diverse ecosystems when it comes to biodiversity but due to stress induced by natural and anthropogenic factors, a worldwide decline threatens the vital ecological functions of these habitats. Studying the infauna provides clues and information about the complexity of seagrass ecosystems and provides information that would facilitate better seagrass area management and associated conservation efforts. The NaGISA sampling protocol was conducted in Calaparan seagrass bed in TINMAR, Guimaras, Philippines between Sept. 2015 and 2016. Overall macrofaunal density was recorded at 21,954.80 ± 36,109.62 ind.m'2 with macrofaunal density higher in 2015 than in 2016 albeit, insignificant except for capitellid polychaetes. Community structure analysis also found similarity in dominance patterns in the subtidal zone with other soft-bottom macrofaunal studies in the Philippines with polychaetes, nematodes, and crustaceans as the respective dominant macrofaunal groups observed. Dominant polychaete families were also found to be cosmopolitan and opportunistic. Granulometric analysis characterized the sediment as pebble to medium sand with mid phi values ranging from -3.69 to 1.10 but poor sorting in all sampling points was observed. Cymodoceaceans dominated the subtidal zone in both years (Halodule pinnifolia in 2015; Cymodocea rotundata in 2016). Correlation analysis showed macrofaunal densities to have a significantly strong negative relationship with sorting index and percent gravel while a strong positive relationship with percent seagrass cover. The poor sediment sorting, coarse sediment character, and seagrass cover were the primary factors influencing the observed decrease in macrofaunal density but the decrease is considered normal for the variability of macrofauna in the area. A clearer picture of macrofaunal interactions would be provided with comparison to intertidal macrofauna of the area in the sampling years and data on additional factors that were not measured in the study.Item Sagip COUGHamilya: Improving prevention, and case management & care seeking in Sitio Durog, Barangay Palaca, MiagaoAsorio, Leslie S.; Clarito, Thea Joy A.; Dolorosa, Rex Victor V.; Marecap, Mitzi N.; Napulan, Andrea Marie N.; Recabar, James Mathew V.; Rodriguez, Sael D.; Velasco, Princess Monic Q. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2019-06)According to the 2018 Morbidity Diseases Reports of Miag-ao’s Rural Health Unit (RHU), Acute Respiratory Infection (ARI) is the main cause of morbidity among the children in the municipality. Upon further review, the community that was found to have the greatest number of ARI cases is that of Barangay Palaca. To contribute with the reduction of ARI cases in the said community, Project Sagip COUGHamilya was implemented in Sitio Durog. This project aims to reduce the number of current ARI cases among children aging 2 months to 11 years old by at least 50% after the 6-week project implementation. In order to accomplish such goal, the team utilized strategic components such as: (1) establishment of a core group called FamiLEADERS, (2) honing the ARI case management knowledge and skills of the barangay health workers (BHWs) through FamiLINANG sessions for BHWs, (3) improving the mothers’ & guardians’ knowledge, attitude, and practices (KAP) towards care seeking and case management for ARI through FamiLINANG sessions for mothers, and (4) raising the children’s awareness on cough etiquette, proper handwashing, and other key health practices through LINIStorya sessions. Upon implementation, the project’s outputs include the 80% increase in the ARI case management knowledge and skills of BHWs, 44.47% increase in the KAP of the mothers & guardians towards care seeking and case management for ARI, and 12.5% increase in the children’s awareness towards cough etiquette, proper handwashing, and other key health practices. All these results were statistically found to be significant improvements. In conclusion, the strategies done by the group significantly improved the care seeking, case management, and key health practices for ARI in Sitio Durog, Barangay Palaca. As a result, Projesct Sagip COUGHamilya contributed to the reduction of ARI cases by 80%, far exceeding the goal of the project and deeming it to be very effective and successful.Item Spatio-temporal analysis of animal rabies cases in Negros Occidental from 2012-2018Asorio, Leslie S.; Clarito, Thea Joy A.; Dolorosa, Rex Victor V.; Meracap, Mitzi N.; Napulan, Andrea Marie N.; Recabar, James Matthew V.; Rodriguez, Sael D.; Velasco, Princess Monic Q. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2019-06)Rabies is particularly dangerous and deadly disease that infects domestic and wild animals and is transmissible to humans. The province of Negros Occidental has been experiencing an uneasy situation on both human and animal rabies in recent years. It posted a rising trend on the number of human deaths due to rabies infection from 2012 to 2018, and has ranked number one among the provinces in Western Visayas with the highest number of positive animal rabies cases in 2017 to 2018. Animal rabies, particularly of canine and feline type, is considered to be a serious threat to public health thus all prevention and control efforts in order to reduce the cases of human rabies are stemming from the identification of high-risk barangays based on the occurrence of canine or feline rabies cases. In this research, a spatio-temporal analysis was performed to determine the high-risk municipalities and temporal pattern of animal rabies cases in Negros Occidental from 2012 to 2018. Spatial analysis identified the major cities such as Bacolod City and Bago City and their surrounding municipalities to be of high risk to animal rabies. The epicenter of cases is slowly shifting towards the central part of the province in subsequent years. Twenty-six (26) space-time clusters of animal rabies cases in Negros Occidental were found to have “intensifying”, “consecutive”, “oscillating”, and “sporadic” time trends. Two clusters classified as “new” hotspots were identified in the central part of the province.Item Survey of pathogenic bacteria in bottom sediments of Iloilo River: An assessment of water sanitary qualityAraneta, 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.Item Knowledge, attitudes, and practices on dengue vectors of households in Tumagboc Catchment Area, Miagao, IloiloArbizo, Jeric L.; Baldevarona, Rosa Lea S.; Caoyonan, Louise Asuncion D.; Gabasa, Marah Febcy J.; Mapa, Fernie Love D.; Patria, Elaine Joy M.; Tenchavez, Darlene Ruth B.; Trivilegio, Enna Fleur C. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2011-03)Previous studies have shown that knowledge, attitudes and practices have an association with the dengue vector control. As such, the independence of mosquito population on the sociodemographic characteristics and KAP of the household heads in Tumagboc Catchment Area, Miagao, Iloilo was tested. Based on the results, the household heads generally are unemployed, married females aging 41 to 50. Their households are composed of 4 to 7 members with no or one child below 15 years, and usually receive below P 1999 per month. Most of them are informed about dengue fever, but only one had suffered from it in the last two years. Moreover, they have moderate knowledge, poor attitudes, but good practices regarding dengue prevention. The container index is 2.71 for crude mosquito larvae and pupae population, and 0.39 for Aedes sp. The house index is 9.72, while the Breteaux indexis 13.19. Chi-square analysis at 0.05 level of significance confirmed the independence of mosquito larvae and pupae population from monthly income, dengue information reception, knowledge, attitudes and practices. A solid reason was the untimely conduct of the study in the beginning of the summer season, when stagnant water has dried up and with few vulnerable breeding sites.Item Risk zone mapping of 2010 dengue fever and dengue hemorrhagic fever cases in the Province of Iloilo based on land coverAndrada, Thresdale; Cañonero, Gertrude Mikee; España, Regine Marie; Puno, Abigail; Sarangaya, Dorothy Rose; Tan, Leonard; Tejada, Ma. Corazon (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2013-04)Dengue is considered as one of the most important vector-borne diseases in many tropical and subtropical countries. Iloilo Province had 8201 cases in 2010. Heterogeneity in the risk of disease transmission results from spatial heterogeneity in both land use and land cover. Thus, the present study was conducted to identify the risk zones of Dengue Fever and Dengue Hemorrhagic Fever in Province of Iloilo in 2010 based on land cover types by using GIS software. Results of the study show that all land covers in the 6th district pose moderately low risk on dengue incidence. In the case of the 1st district of Iloilo, on the other hand, water bodies have the highest probability of dengue incidence, while the rest of the districts (2nd, 3rd, 4th, 5th). built-up areas have the highest probability of dengue incidence. The land cover type in Iloilo, therefore, with the highest risk for dengue incidence are built up areas due to its high population density, multitude of households and stagnant water areas.Item Dengue knowledge, policies, and Aedes Larval population in selected low and high dengue priority areas in Miagao, IloiloAmihan, April Rose D.; Basco, Arriane Mae P.; Escosia, Edmon B.; Monsale, April Joy P.; Solis, Jann Christian V.; Varon, Marianne Joy C. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2009-03)This cross-sectional study aimed to compare the knowledge, practices, and Aedes larval populations between low and high dengue priority areas of Miagao, Iloilo. Questionnaire-guided interviews were conducted to assess the knowledge and practices of the study population. Larval surveys were done to determine Aedes larval populations, expressed as House Index (HI), Container Index (CI), and Breteau Index (BI). Results showed that respondents from the low priority area were more knowledgeable on dengue than the respondents from the high priority area (p<0.05). Dengue preventive practices were found to be the same for both low and high priority areas. There was, however, no significant relationship between dengue knowledge and dengue preventive measures (p<0.05). Results from (he larval survey revealed that both low and high priority areas have HI and BI above the WHO standards (HI<5%; BI<20) and are considered “high risk” areas. Lastly, age (p<0.01) and educational attainment (p<0.05) were found to affect an individual’s dengue knowledge.Item Waist-to-hip ratio, body mass index and hypertension among adult in the San Rafael Catchment Area in Miagao, IloiloAlfabeto, 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.Item Phytoplankton assemblages in contrasting seasons in the area of Banate Bay, Iloilo, PhilippinesAlvarez, Rose Ann T. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2019-06)Banate Bay in Iloilo is one of the major food and occupation contributors in the Panay Island because of its rich biodiversity. This study investigated the phytoplankton assemblage and their diversity with respect to the contrasting seasons namely; December 2012 and June 2013 on the pre-selected nine (9) stations of the Coastal Ecosystem Conservation and Adaptive Management (CECAM) Project. Physicochemical parameters such as salinity, turbidity, DO, and pH did not display seasonality but total suspended solids (TSS) did, with increased values resulting from run-off from the surrounding watershed and rivers. Principal Component Analysis divided the stations during the two months into groups. Station B3 during June 2013 possessed low salinity level, low turbidity level, low pH level and a very high DO level. While the other stations during June 2013 and all the stations during December 2012 possessed higher salinity levels, higher turbidity levels, higher pH levels and lower DO levels. While the PC2 of PCA divided the stations according to the TSS levels and the temperature. All stations during December 2012 showed characteristics of higher TSS levels and lower temperatures while stations during June 2013 were observed to have low TSS levels and higher temperatures. A total of 86 genera falling under six families were identified from the samples, namely: bacillariophyceae (49 genera), dinophyceae (24 genera), cyanophyceae (6 genera), silicoflagellate (4 genera), chlorophyceae (1 genus), euglenophyceae (1 genus) and Miscellaneous (2 genera). In December 2012, a total of 84 genera were identified and 86 genera in June 2013. The top 10 genera with the highest mean densities were Bacteriastrum, Chaetoceros, Eutintinnus, Guinardia, Leptocylindricus, Lioloma, Protoperidinium, Thallasiothrix and Trichodesmium. Pearson’s correlation analysis revealed that water temperature and TSS were the most significant parameters influencing the distribution and seasonal shift in phytoplankton families and genera such as Bacillariophyceae, Others (composed of Euglenophyceae, Chlorophyceae, Myrionecta, and Globigerina), Protoperidinium, and Guinardia. pH and DO had minor influence on phytoplankton distribution. Shannon- Wiener diversity index as a pollution index suggested that the study area was incipiently polluted at stations Bl, B2, and B3 and marginally polluted at Stations B4, B5, GN1, GN2, GS1, and GS2. Despite potential effects of various human activities, the water quality and phytoplankton assemblage of this area has not reached an alarming situation. The current study provides valuable baseline data.
