Stigma towards people with mental health problems (PMHP) is known to have substantial negative impacts on their lives. More in-depth exploration of the stigma and discrimination experienced by PMHP in low- and middle-income countries is needed. Previous research suggests that negative attitudes towards PMHP are widespread among the Filipino general public. However, no study has investigated PMHP’s own experiences of being stigmatised in the Philippines. A qualitative study was conducted on the stigma experienced by PMHP (including people with epilepsy) and its related factors in the Philippines, employing the constructivist grounded theory approach. We analysed data on 39 PMHP collected through interviews with PMHP, their carers, and community health volunteers who know them well. The findings highlight the culturally and socio-economically specific contexts, consequences, and impact modifiers of experiences of stigma. Participants emphasised that PMHP face stigma because of the cultural traits such as the perception of mental health problem as a disease of the family and the tendency to be overly optimistic about the severity of the mental health problem and its impact on their life. Further, stigma was experienced under conditions where mental health care was not readily available and people in the local community could not resolve the PMHP’s mental health crisis. Stigma experiences reduced social networks and opportunities for PMHP, threatened the economic survival of their entire family, and exacerbated their mental health problems. An individual’s reaction to negative experiences can be fatalistic in nature (e.g. believing in it is God’s will). This fatalism can help PMHP to remain hopeful. In addition, traditional communal unity alleviated some of the social exclusion associated with stigma. The study indicates that existing stigma-reduction strategies might have limitations in their effectiveness across cultural settings. Therefore, we propose context-specific practical implications (e.g. emphasis on environmental factors as a cause of mental health problems, messages to increase understanding not only of the possibility of recovery but also of challenges PMHP face) for the Philippines.

The maternal mortality ratio in the Philippines remains high; thus, it will be difficult to achieve the Millennium Development Goals 5 by 2015. Approximately two-thirds of all maternal deaths occur during the postpartum period. Therefore, we conducted the present study to examine the current state of postpartum health care service utilization in the Philippines, and identify challenges to accessing postpartum care. A questionnaire and knowledge test were distributed to postpartum women in the Philippines. The questionnaire collected demographical characteristics and information about their utilization of health care services during pregnancy and the postpartum period. The knowledge test consisted of 11 questions regarding 6 topics related to possible physical and mental symptoms after delivery. Sixty-four questionnaires and knowledge tests were analyzed. The mean time of first postpartum health care visit was 5.1±5.2 days after delivery. Postpartum utilization of health care services was significantly correlated with delivery location (P<0.01). Women who delivered at home had a lower rate of postpartum health care service utilization than women who delivered at medical facilities. The majority of participants scored low on the knowledge test. We found inadequate postpartum health care service utilization, especially for women who delivered at home. Our results also suggest that postpartum women lack knowledge about postpartum health concerns. In the Philippines, Barangay health workers may play a role in educating postpartum women regarding health care service utilization to improve their knowledge of possible concerns and their overall utilization of health care services.

Given the shortage of medical professionals in the Philippines, Barangay Health Workers (BHWs) may play a role in providing postpartum healthcare services. However, as there are no reports regarding BHW activities in postpartum healthcare, we conducted this study to understand postpartum healthcare services and to explore the challenges and motivations of maternal health service providers. Focus group interview (FGI) of 13 participants was conducted as qualitative research methodology at Muntinlupa City. The results were analyzed according to the interview guide. The proceedings of the FGI were transcribed verbatim, and researchers read and coded the transcripts. The codes were then used to construct categories. Four important activities were highlighted among 11 analysis codes. These activities were "Assessment of postpartum women's conditions," "Recommendation to visit a health facility," "Measurement of blood-pressure and vitamin intake," and "Providing postpartum health information." Among five analysis codes, we identified three challenges that BHWs face, which were "No current information regarding postpartum care," "Some postpartum women do not want to receive healthcare services from BHW," and "Too many assigned postpartum women." Among five analysis codes, we identified two reasons for continuing BHW activities, which were "Hospitality to help postpartum women and their family in the community" and "Performance of mission in providing BHW services." This study is the first to evaluate BHW activities in postpartum healthcare services. Our results indicate that BHWs play a potentially important role in evaluating postpartum women's physical and mental conditions through home-visiting services. However, several difficulties adversely affected their activities, and these must be addressed to maximize the contributions of BHWs to the postpartum healthcare system.

Purpose: The World Health Organization advocates that all pregnant women in areas where anemia is prevalent receive supplements of iron and folic acid. However, owing to a myriad of factors, the uptake of iron and folic acid supplementation (IFAS) is still low in many countries. Therefore, this study was conducted to assess the prevalence of IFAS and its associated factors among pregnant women. Patients and Methods: A cross-sectional study was conducted at a hospital in Muntinlupa, Philippines, between March and August 2019 among 280 pregnant women. A systematic random sampling technique was used to select participants. Data were collected using interviewer-administered questionnaires. Multivariable logistic regression analyses were employed to identify factors associated with the prevalence of IFAS among pregnant women. Results: Among 280 pregnant women, a majority (85.6%, n= 238) took IFAS during pregnancy. Among the respondents, 128 (45.9%) women had knowledge about signs and symptoms of anemia, 126 (45.3%) had knowledge of the benefits associated with IFAS, and 42 (15.4%) had knowledge about side effects associated with IFAS. The main sources of information about IFAS were health care providers (41.8%), followed by community health workers (CHWs) (14.6%). Maternal knowledge concerning IFAS benefits (OR = 2.50, CI = 1.04– 5.97, p=0.04) was positively associated with the prevalence of IFAS. Conclusion: Maternal knowledge about the benefits of taking IFAS was significantly associated with the prevalence of IFAS among pregnant women in Muntinlupa, Philippines. There is a pressing need to improve health education on the benefits of IFAS among pregnant women to increase its prevalence. This emphasizes the necessity of increased involvement of health care providers and CHWs to increase women’s knowledge of IFAS benefits and support them through pregnancy.

This study aimed to examine the mental health status and related factors among Vietnamese migrants in Japan during the COVID-19 pandemic. We conducted an online cross-sectional survey between September 21 and October 21, 2021. Along with Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder 7-item (GAD-7) scores, we collected data on demographics, changes in socioeconomic status due to the pandemic, language proficiency, social support, and health conditions. Multivariate logistic regression was performed to identify factors related to symptoms of depression and anxiety. Among 621 participants who completed the questionnaire, moderate-to-severe symptoms of depression (PHQ-9 score ≥ 10 points) and mild-to-severe symptoms of anxiety (GAD-7 score ≥ 5 points) were observed in 203 (32.7%) and 285 (45.9%) individuals, respectively. Factors related to depressive symptoms were age (95% confidence interval [CI]=0.89-0.99), pre-existing health conditions (95% [CI]=1.61–3.76), and a low subjective socioeconomic status (95% [CI]=1.64–3.71). Factors related to anxiety symptoms were being single (95% [CI]=1.01–2.93), having pre-existing health conditions (95% [CI]=1.63–3.88), subjective socioeconomic status (95% [CI]=1.87–3.97), and absence of a partner to discuss one’s health with (95% [CI]=1.11–2.47). Vietnamese migrants in Japan experienced a decrease in income, worsening working conditions, and poor mental health status during the COVID-19 pandemic. Further investigations are necessary to find an effective way to increase their social support and mitigate socioeconomic adversities.

Utilization of healthcare services in postpartum women in the Philippines who delivered at home and the effects on their health: a cross-sectional analytical study Tadashi Yamashita,1 Maria Teresa Reyes Tuliao,2 Magdalena Concel Meana,2 Sherri Ann Suplido,3 Cecilia L Llave,4 Yuko Tanaka,5 Hiroya Matsuo6 1Kobe City College of Nursing, Kobe, Japan; 2Health Department of Muntinlupa, Muntinlupa, Philippines; 3Department of Obstetrics and Gynecology, Philippine General Hospital, Manila, Philippines; 4College of Medicine (CM), University of the Philippine (UP), Manila, Philippines; 5Department of School of Health Sciences, Faculty of Medicine, Tokushima University Graduate School, Tokushima, Japan; 6Department of International Health, Kobe University Graduate School of Health Sciences, Kobe, Japan Background: A low ratio of utilization of healthcare services in postpartum women may contribute to maternal deaths during the postpartum period. The maternal mortality ratio is high in the Philippines. The aim of this study was to examine the current utilization of healthcare services and the effects on the health of women in the Philippines who delivered at home. Methods: This was a cross-sectional analytical study, based on a self-administrated questionnaire, conducted from March 2015 to February 2016 in Muntinlupa, Philippines. Sixty-three postpartum women who delivered at home or at a facility were enrolled for this study. AÂ questionnaire containing questions regarding characteristics, utilization of healthcare services, and abnormal symptoms during postpartum period was administered. To analyze the questionnaire data, the sample was divided into delivery at home and delivery at a facility. Chi-square test, Fisherâ??s exact test, and Mannâ??Whitney U test were used. Results: There were significant differences in the type of birth attendant, area of residence, monthly income, and maternal and child health book usage between women who delivered at home and those who delivered at a facility (P
