Delos Santos, MAEd, RN, Mary Abigail A. Hernandez, MPH, RN, Kristine Joy L. Tomanan, MCD, RN, Laurence Lloyd B.

Nurses have a pivotal role in nurturing the capabilities of individuals, families, and population groups for better health. However, underserved communities in the Philippines, such as those with socioeconomic inadequacies, geographic isolation, and service access problems, have significant limitations in attaining the highest possible level of health. Hence, a community extension service (Project “Lusog-Linang”), employing community-engaged research, was launched with the residents of an underserved locality in Central Luzon. The current paper aimed to describe the engagement of the community residents in describing their current health situation and related priority problems, as well as explore appropriate initiatives to manage the identified problems. \u0000Methods. Community-engaged research was utilized to enable the residents of Barangay San Vicente, Bamban, Tarlac to participate in health capacity building. Particularly, records review and focus group discussions were conducted to assess the community’s health needs and to identify the residents’ perceived problems. The findings were presented in a community assembly, where residents further discussed their priority health concerns and potential interventions to address them. Quantitative data were summarized through descriptive statistics, while qualitative information was synthesized via content analysis. \u0000Results. The priority community health problems included healthcare inaccessibility (trained staff, health equipment, and facility access), food insecurity, water supply limitations, and environmental sanitation. Moreover, there was inadequate knowledge and skills among the residents in health promotion, disease prevention, and illness management. While Barangay San Vicente had limited socioeconomic resources to optimize their health capacities, the sense of community among the residents is a vital resource towards empowering them to improve their health. \u0000Conclusion. The results could be utilized as a launching pad for developing appropriate health programs for theresidents of Barangay San Vicente. Hence, the next steps in Project “Lusog-Linang” should include the identification and training of core group members toward community mobilization, and further exploring collaborative and sustainable partnerships across organizations to ensure that the community will have long-term solutions to their problems. Consequently, this project could guide public health workers in ensuring the active involvement and participation of the community members in managing their own health.","PeriodicalId":6994,"journal":{"name":"Acta Medica Philippina","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141649184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
