"I'll take them another day": A qualitative study exploring the socio-behavioral complexities of childhood vaccination in urban poor settlements.

Despite improvement over recent decades, childhood vaccination uptake remains a concern across countries. The World Health Organization observed that over 25 million children missed out on one or more vaccines in 2021, with urban poor and other marginalized groups being the most affected. Given the higher risk of disease transmission and vaccine-preventable diseases (VPD) outbreaks across densely populated urban slums, identifying effective interventions to improve childhood vaccination in this vulnerable population is crucial. This study explored the behavioral and social factors influencing childhood vaccination uptake in urban informal settlements in Nairobi, Kenya. A grounded theory approach was employed to develop a theoretical account of the socio-behavioral determinants of childhood vaccination. Five focus group discussions (FGDs) were conducted with purposively sampled caregivers of children under five years of age residing in informal settlements. The Theory of Planned Behavior guided the structuring of the FGD questions. An iterative process was used to analyze and identify emerging themes. Thirty-nine caregivers (median age 29 years) participated in the FGDs. From the analysis, four main thematic categories were derived. These included attitude factors such as perceived vaccine benefits, cultural beliefs, and emotional factors including parental love. Additionally, subjective norms, like fear of social judgment, and perceived behavioral control factors, such as self-control and gender-based influences, were identified. Furthermore, a number of practical factors, including the cost of vaccines and healthcare providers attitude, also affected the uptake of vaccination. Various social, behavioral, cultural, and contextual factors influence caregiver vaccination decisions in urban poor settings. Community-derived and context-specific approaches that address the complex interaction between socio-behavioral and other contextual factors need to be tested and applied to improve the timely uptake of childhood vaccinations among marginalized populations.

Financial protection and equity in the healthcare financing system in Iran: a cross-sectional study among slum dwellers with type 2 diabetes.

OBJECTIVES: This study was conducted to assess financial protection and equity in the healthcare financing system among slum dwellers with type 2 diabetes (T2D) in Iran in 2022. DESIGN: Cross-sectional study. SETTING: Primary care centres in Iran were selected from slums. PARTICIPANTS: Our study included 400 participants with T2D using a systematic random sampling method. Patients were included if they lived in slums for at least five consecutive years, were over 18 years old and did not have intellectual disabilities. PRIMARY AND SECONDARY MEASURES: A self-report questionnaire was used to assess cost-coping strategies vis-à-vis T2D expenditures and factors influencing them, as well as forgone care among slum dwellers. RESULTS: Of the 400 patients who participated, 53.8% were female. Among the participants, 27.8% were illiterate, but 30.3% could read and write. 75.8% had income below 40 million Rial. There was an association between age, education, income, basic insurance, supplemental insurance and cost-coping strategies (p<0.001). 88.2% of those with first university degree used health insurance and 34% of illiterate people used personal savings. 79.8% of people with income over 4 million Rial reported using insurance to cope with healthcare costs while 55% of those with income under 4 million Rial reported using personal savings and a combination of health insurance and personal savings to cope with healthcare costs. As a result of binary logistic regression, illiterate people (adjusted OR=16, 95% CI 3.65 to 70.17), individuals with low income (OR 5.024, 95% CI 2.42 to 10.41) and people without supplemental insurance (OR 1.885, 95% CI 0.03 to 0.37) are more likely to use other forms of cost-coping strategies than health insurance. CONCLUSIONS: As a result of insufficient use of insurance, cost-coping strategies used by slum dwellers vis-à-vis T2D expenditures do not protect them from financial risks. Expanding universal health coverage and providing supplemental insurance for those with T2D living in slums are recommended. Iran Health Insurance should adequately cover the costs of T2D care for slum dwellers so that they do not need to use alternative strategies.

Protocol for process evaluation of ARTEMIS cluster randomised controlled trial: an intervention for management of depression and suicide among adolescents living in slums in India.

INTRODUCTION: There are around 250 million adolescents (10-19 years) in India. The prevalence of mental health-related morbidity among adolescents in India is approximately 7.3%. Vulnerable subpopulations among adolescents such as those living in slum communities are particularly at risk due to poor living conditions, financial difficulty and limited access to support services. Adolescents' Resilience and Treatment nEeds for Mental Health in Indian Slums (ARTEMIS) is a cluster randomised controlled trial of an intervention that intends to improve the mental health of adolescents living in slum communities in India. The aim of this paper is to describe the process evaluation protocol for ARTEMIS trial. The process evaluation will help to explain the intervention outcomes and understand how and why the intervention worked or did not work. It will identify contextual factors, intervention barriers and facilitators and the adaptations required for optimising implementation. METHODS: Case study method will be used and the data will include a mix of quantitative metrics and qualitative data. The UK Medical Research Council's guidance on evaluating complex interventions, the Reach, Efficacy, Adoption, Implementation and Maintenance Framework and the Affordability, Practicability, Effectiveness and cost-effectiveness, Acceptability, Safety/Side Effects and, Equity criteria will be used to develop a conceptual framework and a priori codes for qualitative data analysis. Quantitative data will be analysed using descriptive statistics. Implementation fidelity will also be measured. DISCUSSION: The process evaluation will provide an understanding of outcomes and causal mechanisms that influenced any change in trial outcomes. ETHICS AND DISSEMINATION: Ethics Committee of the George Institute for Global Health India (project number 17/2020) and the Research Governance and Integrity Team, Imperial College, London (ICREC reference number: 22IC7718) have provided ethics approval. The Health Ministry's Screening Committee has approved to the study (ID 2020-9770). TRIAL REGISTRATION NUMBER: CTRI/2022/02/040307.

Increasing Contraceptive Use Through Free Family Planning Special Days in Poor Urban Areas in Francophone West Africa.

INTRODUCTION: In francophone West Africa (FWA), contraceptive uptake remains limited, often due to geographic, economic, and social barriers. With technical support from The Challenge Initiative (TCI), municipalities and health systems implemented Family Planning Special Days (FPSDs) to improve family planning (FP) uptake and reduce high unmet need. The FPSD intervention consisted of organizing free FP services on a monthly or quarterly basis over 2 to 5 consecutive days within health facilities or sites close to the population. These events helped to educate, inform, and mobilize the community around FP and improve geographic and financial access to FP services. We describe the process of implementing FPSDs in FWA countries and analyze the results. METHODS: We used several techniques and data sources in our descriptive analysis, including document review of activity reports, analysis of health management information system data, and retrospective data collection on the profile of FPSD users and implementation costs. RESULTS: Between July 2020 and June 2021, municipalities and health systems collaborated to hold 1,046 FPSDs in 452 health facilities in 10 FWA cities. This collaboration was made possible through the establishment of city-level management and coordination units composed of municipal, health system, and TCI focal points. In the 10 FWA cities, 181,792 people were made aware of the FPSDs and 71,669 contraceptive users were served. The overall cost of organizing the FPSDs was about 145382501 Central African CFA francs (US$252839), 35% of which came from the municipalities' local financial contribution. DISCUSSION: Results from our analysis showed that, with appropriate financial support from municipalities, the health system could offer high-quality free FP services. Nonetheless, there are still challenges to the sustainability of conducting FPSDs, including the availability of contraceptive products and continued financing of the strategy during system shocks such as the COVID-19 pandemic.

Caesarean delivery and neonatal mortality: evidence from selected slums in and around Dhaka city, Bangladesh- A prospective cohort study.

BACKGROUND: This study examined the neonatal mortality for newborn of women who delivered by caesarean section or vaginally using a prospective cohort. METHODS: A total of 6,989 live births registered from 2016 to 2018, were followed for neonatal survival from the selected slums of Dhaka (North and South) and Gazipur city corporations, where icddr,b maintained the Health and Demographic Surveillance System (HDSS). Neonatal mortality was compared by maternal and newborn characteristics and mode of delivery using z-test. Logistic regression model performed for neonatal mortality by mode of delivery controlling selected covariates and reported adjusted odd ratios (aOR) with 95% confidence interval (CI). RESULTS: Out of 6,989 live births registered, 27.7% were caesarean and the rest were vaginal delivery; of these births, 265 neonatal deaths occurred during the follow-up. The neonatal mortality rate was 2.7 times higher (46 vs. 17 per 1,000 births) for vaginal than caesarean delivered. Until 3rd day of life, the mortality rate was very high for both vaginal and caesarean delivered newborn; however, the rate was 24.8 for vaginal and 6.3 per 1,000 live births for caesarean delivered on the 1st day of life. After adjusting the covariates, the odds of neonatal mortality were higher for vaginal than caesarean delivered (aOR: 2.63; 95% CI: 1.82, 3.85). Additionally, the odds were higher for adolescent than elderly adult mother (aOR: 1.60; 95% CI: 1.03, 2.48), for multiple than singleton birth (aOR: 5.40; 95% CI: 2.82, 10.33), for very/moderate (aOR: 5.13; 95% CI: 3.68, 7.15), and late preterm birth (aOR: 1.48; 95% CI: 1.05, 2.08) than term birth; while the odds were lower for girl than boy (aOR: 0.74; 95% CI: 0.58, 0.96), and for 5th wealth quintile than 1st quintile (aOR: 0.59, 95% CI: 0.38, 0.91). CONCLUSION: Our study found that caesarean delivered babies had significantly lower neonatal mortality than vaginal delivered. Therefore, a comprehensive delivery and postnatal care for vaginal births needed a special attention for the slum mothers to ensure the reduction of neonatal mortality.

Uncovering the causes and socio-demographic constructs of stillbirths and neonatal deaths in an urban slum of Karachi.

INTRODUCTION: Neonatal deaths and stillbirths are significant public health concerns in Pakistan, with an estimated stillbirth rate of 43 per 1,000 births and a neonatal mortality rate of 46 deaths per 1,000 live births. Limited access to obstetric care, poor health seeking behaviors and lack of quality healthcare are the leading root causes for stillbirths and neonatal deaths. Rehri Goth, a coastal slum in Karachi, faces even greater challenges due to extreme poverty, and inadequate infrastructure. This study aims to investigate the causes and pathways leading to stillbirths and neonatal deaths in Rehri Goth to develop effective maternal and child health interventions. METHODS: A mixed-method cohort study was nested with the implementation of large maternal, neonatal and child health program, captured all stillbirths and neonatal death during the period of May 2014 till June 2018. The Verbal and Social Autopsy (VASA) tool (WHO 2016) was used to collect primary data from all death events to determine the causes as well as the pathways. Interviews were conducted both retrospectively and prospectively with mothers and caregivers. Two trained physicians reviewed the VASA form and the medical records (if available) and coded the cause of death blinded to each other. Descriptive analysis was used to categorize stillbirth and neonatal mortality data into high- and low-mortality clusters, followed by chi-square tests to explore associations between categories, and concluded with a qualitative analysis. RESULTS: Out of 421 events captured, complete VASA interviews were conducted for 317 cases. The leading causes of antepartum stillbirths were pregnancy-induced hypertension (22.4%) and maternal infections (13.4%), while obstructed labor was the primary cause of intrapartum stillbirths (38.3%). Neonatal deaths were primarily caused by perinatal asphyxia (36.1%) and preterm birth complications (27.8%). The qualitative analysis on a subset of 40 death events showed that health system (62.5%) and community factors (37.5%) contributing to adverse outcomes, such as delayed referrals, poor triage systems, suboptimal quality of care, and delayed care-seeking behaviors. CONCLUSION: The study provides an opportunity to understand the causes of stillbirths and neonatal deaths in one of the impoverished slums of Karachi. The data segregation by clusters as well as triangulation with qualitative analysis highlight the needs of evidence-based strategies for maternal and child health interventions in disadvantaged communities.

Community stigma, victimization, and coping strategies among gay, bisexual, and other cis-gender men who have sex with men in slum communities in Ghana. BSGH-003.

BACKGROUND: Gay, bisexual, and cis-gender men who have sex with men (GBMSM) face severe consequences, especially within stigmatized environments. However, very little is known about the experiences of GBMSM living in slums in SSA and Ghana. This study investigates the experiences of stigma, victimization, and coping strategies and proposes some interventional approaches for combating stigma facing GBMSM in slum communities. METHODS: We engaged GBMSM living in slums in two major Ghanaian cities. We used a time-location sampling and collected data through in-depth individual interviews. Two major themes emerged from the study: (1) insecurities and criminalization of GBMSM activity, and (2) GBMSM coping strategies. RESULTS: Findings show GBMSM experienced negative attitudes from the community due to their sexual behavior/orientation. GBMSM also developed coping strategies to avert negative experiences, such as hiding their identities/behavior, avoiding gender non-conforming men, and having relationships with persons outside their communities. CONCLUSION: We propose interventions such as HIV Education, Empathy, Empowerment, Acceptance, and Commitment Therapy as possible measures to improve the experiences of GBMSM living in Ghanaian slum communities.

A qualitative perspective of working women care providers and care receivers on eldercare: a study from India.

BACKGROUND: The paper aims to explore the elderly caregiving process in India from the perspective of both elderly as well as working women care providers, along with the challenges faced and the coping strategies adopted by them during the process. METHODS: In-depth interviews with 48 participants (care providers and care receivers) from 25 multi-generational households were conducted in the slums of Mumbai and analysed using QSR-NVivo-10. RESULTS: Working women care providers supported the needs of the dependent elderly along with performing household chores and paid work. However, the way the care was perceived and demanded, was not often same as delivered by the care providers. Care provider suffered silently with poor social, physical and emotional welling in absence of support system and lack of time. Sometimes, physically exhausted care providers unknowingly resorted to elderly abuse and neglect. At the same time, a bidirectional flow of support from elderly also existed in the form of childcare, household chores and financial support. Though caregiving overstrained the care providers, strong family ties, acknowledgement of the contributions of the elderly during their young days, and the desire to set a precedent for the young generation did not let them step back from their duties. The main coping mechanism for both care receivers and providers was largely centred around the notion of acceptance of their situation. CONCLUSION: Conversations between generations can help in enhancing family ties and reduce conflicts. The support of family and community can also ease the burden of caregiving.

Unmet and unperceived needs for type 2 diabetes self-management among slum dwellers in Iran: a cross-sectional study.

AIM: This study aimed to identify unmet and unperceived needs for T2D self-management among those residing in Tabriz slums, Iran, in 2022. BACKGROUND: Type 2 diabetes (T2D) and its complications are more common among slum dwellers. T2D is a lifelong disease that requires continuous care. By contrast, slum dwellers are less likely to adhere to standard health care. METHODS: This study is cross-sectional. We included 400 patients using a systematic random sampling method. Unmet and unperceived needs were assessed through a researcher-made questionnaire. The questionnaire was developed based on Iran's Package of Essential Non-Communicable Diseases (IraPEN) instructions and an expert panel. Data were analyzed using SPSS version 22. FINDINGS: Need for more healthcare cost coverage by insurance organizations (85.5%), financial support to provide medicine (68%), free and accessible sports equipment in the area (48.5%), continuous access to blood sugar test instruments (47.8%), know how to test blood sugar and interpret the results (47.7%), more communication with healthcare providers (42.3%), and detailed education from health professionals (41.2%) were the most common unmet needs. The least perceived need was to know how to care for feet (16%).

Interplay of missed opportunity for vaccination and poor response to the vaccine led to measles outbreak in a slum area of Eastern Mumbai, India.

In the third week of September 2022, an outbreak of measles was reported from a slum in Eastern Mumbai, India. We sought to investigate whether failure to vaccinate or vaccine failure was the cause. We constructed an epidemic curve, drew a spot map, and calculated the attack rate and case-fatality ratio. We calculated vaccine effectiveness (VE) for one and two doses of measles vaccine in an unmatched case-control study and did stratified analysis by sex, availability of vaccination card, and migrant status. We identified 358 cases and four deaths with a 11.3% attack rate and 1.1% case fatality, both being highest among 0-24-month-old boys. The epidemic curve suggested a propagated mode of spread. The VE for two doses was 64% (95% confidence interval (CI): 23-73%) among under-5-year-old children and 70% (95% CI: 28-88%) among 5-15-year-old children. Failure to vaccinate, consequent to the COVID-19 pandemic, and vaccine hesitancy might have led to the accumulation of susceptible children in the community. Additionally, the occurrence of case-patients among vaccinated suggests reduced VE, which needs further investigation into humoral and cell-mediated immunity as well as contributory factors including nutritional status. Outbreak response immunization to complete immunization of missed and dropout children was carried out to control the outbreak.

[Perception of the food environment by Brazilian slum residents: a qualitative study]. / Percepção dos residentes de favelas brasileiras sobre o ambiente alimentar: um estudo qualitativo.

Food availability in the territory can influence food consumption by the population. However, it is important to understand how people perceive their food environment to see how food availability affects consumption in different contexts. This study aimed to assess the perception of the food environment by Brazilian slum residents in their neighborhoods. This is a qualitative study, with online focus groups guided by a script in order to gather collective discourses about access to food in Brazilian slums. The invitation to participate in this study was made through social media, and community leaders and nongovernmental organizations with actions in slums were contacted using the snowball sampling technique. Grounded theory analysis was applied with the technique of thematic networks. Access to food for slum residents involves lack of resources and essential elements for an adequate and healthy diet, such as lack of information about food, low income, and low availability of stores that sell healthy food at affordable prices. Public programs and policies are required to encourage the expansion of food and nutritional security resources, such as vegetable gardens and markets, to increase the supply and sell healthy food at affordable prices in slums. Actions are also required to address the complexity of obstacles faced by slum residents in the access to healthy foods.

A disponibilidade de venda de alimentos no território pode influenciar no consumo alimentar da população. Entretanto, é importante compreender como as pessoas percebem o seu ambiente alimentar para se entender como essa disponibilidade afeta seu consumo em contextos distintos. O objetivo foi avaliar a percepção dos moradores de favelas brasileiras sobre o ambiente alimentar em suas vizinhanças. Estudo qualitativo, em que foram realizados grupos focais online guiados por um roteiro para reunir discursos coletivos sobre o acesso aos alimentos em favelas brasileiras. O convite ocorreu por meio das redes sociais e do contato com líderes comunitários e organizações não governamentais que atuam em favelas, por meio da técnica de amostragem "bola de neve". Para a análise, foi utilizada a abordagem grounded theory (teoria fundamentada) e, como técnica, foi empregada a análise de redes temáticas. O acesso aos alimentos por moradores de favelas é permeado pela falta de recursos e elementos fundamentais para uma alimentação adequada e saudável, como: a falta de informação sobre alimentação; a renda insuficiente; e a baixa disponibilidade de estabelecimentos que comercializam alimentos saudáveis a preços acessíveis. São necessários programas e políticas públicas que incentivem a ampliação de equipamentos de segurança alimentar e nutricional, como hortas e feiras, e que aumentem a oferta de alimentos saudáveis com valores baixos nas favelas. Também são necessárias ações que abordem a complexidade das barreiras enfrentadas por moradores de favelas para ter acesso aos alimentos saudáveis.

La disponibilidad de venta de alimentos en el territorio puede influir en el consumo alimentario de la población. Sin embargo, es importante comprender la manera en que las personas perciben su entorno alimentario para comprender cómo esta disponibilidad afecta su consumo en diferentes contextos. El objetivo fue evaluar la percepción de los residentes de favelas brasileñas sobre el entorno alimentario en sus vecindarios. Estudio cualitativo, en el que se formaron grupos focales en línea orientados por un guion con el objetivo de reunir discursos colectivos sobre el acceso a los alimentos en favelas brasileñas. La invitación se dio por medio de las redes sociales y mediante el contacto con líderes comunitarios y organizaciones no gubernamentales que trabajan en favelas, utilizando la técnica de muestreo "bola de nieve". Para el análisis, se utilizó el enfoque de la grounded theory (teoría fundamentada) y, como técnica, se empleó el análisis de redes temáticas. El acceso a los alimentos de los habitantes de las favelas está permeado por la falta de recursos y elementos fundamentales para una alimentación adecuada y sana, tales como: la falta de información sobre la alimentación, los bajos ingresos y la poca disponibilidad de establecimientos que vendan alimentos sanos a precios asequibles. Se necesitan programas y políticas públicas para fomentar la ampliación de equipos de seguridad alimentaria y nutricional, como huertas y mercadillos, que aumenten la oferta y vendan alimentos sanos a precios asequibles en las favelas. También se necesitan acciones para abordar la complejidad de las barreras que enfrentan los residentes de las favelas para acceder a alimentos sanos.

Social determinants of chronic diseases reporting among slum dwellers in Egypt.

The high prevalence of chronic diseases in urban slums poses increasing challenges to future social and economic development for these disadvantaged areas. Assessing the health status of slum residents offers guidance for formulating appropriate policies and interventions to improve slum residents' health outcomes. This research aimed to identify the social determinants of chronic diseases reporting among slum dwellers in Egypt. A cross-sectional survey was conducted from March to December 2021 in three slum areas in Giza governorate, Egypt, including 3,500 individuals. We constructed an asset index and a welfare index to measure the economic status and living conditions of slum residents, respectively. We used these indices, along with demographic and socio-economic factors, as independent variables in the analysis. We modeled factors associated with health status using a two-level mixed logistic model to control the effects of slum areas and the potential correlation between household members. The study contributed significantly to a better understanding of the context in which slum dwellers live and the interlinkages among poor living conditions, low economic status, and health outcomes. The results showed a high rate of self-reported chronic diseases among adults aged 18 and older, reaching more than 22%, while it did not exceed 2.0% among children in the slum areas. Therefore, measuring the determinants of chronic diseases was limited to adults. The sample size was 2530 adults after excluding 970 children. The prevalence of chronic diseases among adults ranged between 16.3% in Zenin and 22.6% in Bein El Sarayat. Our findings indicated that low socio-economic status was significantly associated with reporting chronic diseases. Future policies should be dedicated to improving living conditions and providing necessary healthcare services for these vulnerable areas.

Utilizing a multi-stage transition model for analysing child stunting in two urban slum settlements of Nairobi: A longitudinal analysis, 2011-2014.

INTRODUCTION: Stunting is common among children in many low and middle income countries, particularly in rural and urban slum settings. Few studies have described child stunting transitions and the associated factors in urban slum settlements. We describe transitions between stunting states and associated factors among children living in Nairobi slum settlements. METHODS: This study used data collected between 2010 and 2014 from the Nairobi Urban and Demographic Surveillance System (NUHDSS) and a vaccination study nested within the surveillance system. A subset of 692 children aged 0 to 3 years, with complete anthropometric data, and household socio-demographic data was used for the analysis. Height-for-age Z-scores (HAZ) was used to define stunting: normal (HAZ ≥ 1), marginally stunted (-2 ≤ HAZ < -1), moderately stunted (-3 ≤ HAZ < -2), and severely stunted (HAZ < -3). Transitions from one stunting level to another and in the reverse direction were computed. The associations between explanatory factors and the transitions between four child stunting states were modeled using a continuous-time multi-state model. RESULTS: We observed that 48%, 39%, 41%, and 52% of children remained in the normal, marginally stunted, moderately stunted, and severely stunted states, respectively. About 29% transitioned from normal to marginally stunted state, 15% to the moderately stunted state, and 8% to the severely stunted state. Also, 8%, 12%, and 29% back transitioned from severely stunted, moderately stunted, and marginally stunted states, to the normal state, respectively. The shared common factors associated with all transitions to a more severe state include: male gender, ethnicity (only for mild and severe transition states), child's age, and household food insecurity. In Korogocho, children whose parents were married and those whose mothers had attained primary or post-primary education were associated with a transition from a mild state into a moderately stunted state. Children who were breastfed exclusively were less likely to transition from moderate to severe stunting state. CONCLUSION: These findings reveal a high burden of stunting and transitions in urban slums. Context-specific interventions targeting the groups of children identified by the socio-demographic factors are needed. Improving food security and exclusive breastfeeding could potentially reduce stunting in the slums.

Evaluation of the primary health care expansion program with public-private partnership in slum areas from the perspective of stakeholders: a qualitative study.

BACKGROUND: Today, economic and social determinants of health in slum settlements are at the policymakers' center of attention. Iran has had an excellent experience in the Primary Health Care Program. This study aimed to evaluate the Primary Health Care Expansion Program with public-private partnerships in slum areas of Iran from the perspective of stakeholders in 2022. METHODS: This qualitative study was conducted using the framework content analysis method. Participants were 17 experts and health managers involved in The Primary Health Care Expansion with Public-Private Partnerships in the suburban areas at the medical universities of Khorasan Razavi province in the east of Iran, who were selected through purposive sampling via snowball method. For data collection, a semi-structured interview was done and framework content analysis was used for data analysis and results categories based on the SWOT. RESULTS: The study identified 23 main themes and 112 sub-themes, which were then grouped into four main categories - strengths, weaknesses, opportunities, and threats using the SWOT model. CONCLUSION: Results of the study showed the internal and external factors affecting Primary Health Care Expansion with Public-Private Partnerships in suburban areas. This situational analysis can help health policymakers to better understand the performance of health facilities.

Serosurveillance among urban slum and non-slum populations immunized with COVID-19 vaccines in Bangladesh.

Using two rounds of serosurveillance, we aimed to observe the COVID-19 vaccination status and the dynamics of antibody responses to different vaccines among urban slum and non-slum populations of Bangladesh. Adults (>18 years) and children (10-17 years) were enrolled in March and October 2022. Data including COVID-19 vaccine types and dosage uptake were collected. SARS-CoV-2 spike (S)-specific antibodies were measured in blood. The proportion of vaccinated children was significantly lower among slum than non-slum populations. Two doses of vaccines showed an increase in the level of anti-S-antibodies up to 2 months, followed by reduced levels at 2-6 months and a resurgence at 6-12 months. Children showed significantly higher anti-S-antibodies after two doses of the Pfizer-BioNTech vaccine than adults; however, after 6 months, the level of antibodies declined in younger children (10 - < 12 years). In a mixed vaccine approach, mRNA vaccines contributed to the highest antibody response whether given as the first two doses or as the third dose. Our findings emphasized the need for increasing the coverage of COVID-19 vaccination among slum children and booster dosing among all children. The use of mRNA vaccines in the mixed vaccination approach was found to be useful in boosting the antibody response to SARS-CoV-2.

Preterm birth and neonatal mortality in selected slums in and around Dhaka City of Bangladesh: A cohort study.

BACKGROUND: Although under-five mortality has declined appreciably in Bangladesh over the last few decades, neonatal mortality still remains high. The objective of the study is to assess the level and determinants of preterm birth and the contribution of preterm birth to neonatal mortality. METHODS: Data for this study came from selected slums in and around Dhaka city, where; since 2015, icddr,b has been maintaining the Health and Demographic Surveillance System (HDSS). The HDSS data were collected by female Field Workers by visiting each household every three months; however, during the visit, data on the Last Menstrual Period (LMP) were also collected by asking each eligible woman to ascertain the date of conception. Gestational age was estimated in complete weeks by subtracting LMP from the date of the pregnancy outcome. In this study, 6,989 livebirths were recorded by HDSS during 2016-2018, and these births were followed for neonatal survival; both bivariate and multivariate analyses were performed. RESULTS: Out of total births, 21.7% were born preterm (before 37 weeks of gestation), and sub-categories were: 2.19% for very preterm (28 to 31 weeks), 3.81% for moderate preterm (32 to 33 weeks), and 15.71% for late preterm (34 to 36 weeks). The study revealed that preterm babies contributed to 39.6% of neonatal deaths; however, the probability of death was very high on the 1st day of birth (0.124 for very preterm, 0.048 for moderate preterm, 0.024 for late preterm, and 0.013 for term birth), and continued until the 3rd day. In the regression analysis, compared to the term neonates, the odds of neonatal mortality were 8.66 (CI: 5.63, 13.32, p<0.01), 4.13 (CI: 2.69, 6.34, p<0.01) and 1.48 (CI: 1.05, 2.08, p<0.05) respectively for very, moderate, and late preterm birth categories. The population attributable fraction for neonatal mortality was 23%, and sub-categories were 14% for very preterm, 10% for moderate preterm, and 6% for late preterm. CONCLUSIONS: Although urban slums are in proximity to many health facilities, a substantial proportion of preterm births contribute to neonatal deaths. So, pregnant women should be targeted, to ensure timely care during pregnancy, delivery, and post-partum periods to improve the survival of new-borns in general and preterm birth in particular.

The urban-poor vaccination: Challenges and strategies in low-and-middle income countries.

Vaccination is one of the success stories of public health. The benefit of vaccination goes beyond individual protection to include promoting population well-being, improving cognitive development, and increasing economic productivity. However, the existing inequalities in the access to vaccination undermines its impact. There are significant variations in the coverage of vaccination between and within countries. Despite that urban populations have better access to health services; evidence has shown that the urban poor have the worst health indicators including vaccination uptake. Additionally, there are unique challenges affecting vaccination in urban settings, especially in urban slums. This paper has discussed key challenges some of the proposed interventions that can improve urban vaccination service delivery.

Effectiveness of community-based sports programs on mental health in brazilian favelas

Based on current research and broad concepts, this research provides an overview of the possible effects of community-based sports programs on mental health in Brazilian favelas. The research study aims to determine the effectiveness of community-based sports programs on mental health in the Brazilian favelas. Although there may not be as many particular studies on this subject, a larger body of research indicates that physical activity, especially sports, might improve mental health by lowering stress levels and generating endorphins. Beyond just providing physical activity,community-based sports programs in Brazilian favelas promote social ties, community participation, and empowerment, all essential for building resilience in difficult socioeconomic contexts. For measuring, the research study used smart PLS software and generated results, including descriptive statistics and correlation coefficients, explaining the smart PLS Algorithm model between them. With an emphasis on goal-setting, discipline,and collaboration, the programs support the healthy development of young people and may even serve as a deterrent to dangerous behavior. However, efficacy varies depending on elements likecultural relevance and program design. Overall, the result found a positive and significant link between community-based sports programs and mental health in Brazilian favelas. Recent research on community-based sports programs in Brazilian favelas and their unique mental health effects is advised to better comprehend these dynamics (AU)

"If the food is finished after my brother eats then we (girls) sleep hungry." Food insecurity and dietary diversity among slum-dwelling adolescent girls and boys in Pakistan: A mixed methods study.

To explore gender differences in food insecurity (FI) and minimum dietary diversity (MDD) among adolescent girls and boys in a slum community in Karachi, we employed an explanatory sequential mixed methods study that included a survey of 391 girls and boys of 10-19 years of age and followed by semi-structured interviews of eight purposely selected food insecure adolescents. Survey data was analyzed by Cox proportional algorithm and adjusted prevalence ratios (APR) with 95% confidence intervals (CI) were estimated for associated factors of FI and thematic analysis was undertaken for qualitative work. Meta inferences for mixed methods study were drawn by joint display analysis of survey results juxtaposed to qualitative findings. Overall, FI among adolescents was prevalent (46.5%) which was not different between boys (52.7%) and girls (47.3%) (APR 0.8, (95% CI 0.6, 1.2); p-value-0.4). MDD (5/10 food groups consumed) was achieved by only 23.0% and it was also not different between boys (25.1%) and girls (20.9%) (p-value-0.3). The survey found no significant difference in FI and MDD between boys and girls however, qualitative findings provided insight into the cultural practices at mealtimes that prefer boys. Qualitative results contrasted the survey results and revealed the increased vulnerability of girls towards FI and low MDD compared to boys due to gender norms.

Seasonal Diversity in Mosquito Larval Ecology and Its Public Health Implications in Urban Slums of Lagos, Nigeria.

Mosquito-borne diseases (MBDs) are major public health burdens in tropical nations, including Nigeria. This study assessed mosquito larval species composition, abundance, and abiotic factors influencing mosquito breeding in slum communities of Lagos with the goal of informing MBD control measures. Three slum communities-Bariga, Makoko, and Ajegunle-were selected along with the nonslum community of Ikeja, which served as a control site. Larval sampling was done using the standard dipping technique between December 2021 and July 2022 across the dry and wet seasons. Mosquito larvae were raised to adults and identified using morphological keys and molecular assays. A total of 57,753 immature mosquitoes were collected from all study sites, with a significantly (P < 0.05) greater abundance in the dry season than the wet season. The majority (98.1%) of the mosquitoes collected belonged to Culex pipiens s.l., the only species found during the dry season in almost all locations. In the wet season, species identified from all sites combined were Anopheles gambiae ss., Anopheles arabiensis, Aedes aegypti, Aedes albopictus, Cx. pipiens s.l., and Lutzia tigripes, with Ajegunle having the greatest species diversity (H = 0.593). Among physicochemical parameters measured, only water temperature had a significant positive correlation (r = 0.934, P = 0.020) with larval densities in Ajegunle only. Permanent mosquito-breeding habitats had significantly greater larval densities than temporary habitats within the slum communities. These findings could inform the development of integrated vector control strategies that address the different species of mosquitoes in the fight against MBDs in urban slums.
