Corneal ulcers and the risk of visual impairment in a matched cohort study in Nepal

PurposeWe estimated the association between corneal ulcer and two outcomes: visual impairment and vision-related quality of life. We investigated for differential effects by rural/urban location. DesignPopulation-based matched prospective cohort study. MethodsWe followed 540 incident corneal ulcer cases identified in a cluster randomized trial in Nepal. Cases were pair-matched to individuals without incident corneal ulcers by age, sex and location using incidence density sampling. Clinical examinations were performed to assess outcomes in both groups after 12 months, which included visual acuity and a modified version of the Hong Kong vision-related quality of life questionnaire. Results392 matched pairs had complete outcome data and were included in the analyses. Median age was 42 years (interquartile range [IQR]: 28, 53) and 63.8 % were female. After controlling for education and occupation, corneal ulcer was associated with an approximately 1-line reduction in visual acuity (0.11 logMAR units, 95 % CI 0.06 to 0.15, P < 0.001), and with an increased risk of low vision/blindness (adjusted risk ratio 1.89, 95 % CI 1.44 to 2.48, P < 0.001). Corneal ulcer was associated with lower vision-related quality of life on the 20-question questionnaire (adjusted mean difference in score -1.69, 95 % CI -2.78 to -0.61, P = 0.002). We were unable to demonstrate effect modification for any outcome by rural/urban status. ConclusionsWe observed worse visual acuity and lower vision-related quality of life among those with incident corneal ulcers compared to those without. The population-based design, which captured the full spectrum of disease, confirms that corneal ulcers are an important cause of vision loss in the general population of Nepal and highlights the need for effective community-based corneal ulcer prevention interventions.

The effectiveness of a suicide prevention program in primary care clinics supported by community public health resources: A difference-in-differences analysis

The importance of appropriate and intensive follow-up management for individuals identified with suicide risk through screening is highlighted. The Link between Primary Care Clinic and Public Health Resources Intervention(LinkPC-PH), a suicide prevention program in primary care clinics supported by community public health resources, was implemented at the district level in 2017. The purpose of the present study is to evaluate the effectiveness of the LinkPC-PH intervention by comparing suicide rates before(2014-2016) and after(2017-2019) implementation of the intervention using a difference-in-differences design. The LinkPC-PH comprises several dimensions of intervention including screening, risk assessment of suicidality, and referral in primary care clinics and crisis contact within 24 hours, case management, and safety planning led by public health professionals. After adjustment for district-level confounders, an intervention-implemented district had 2.87 fewer suicide deaths per 100,000 people in a population sample at post-intervention than would have been expected from the same trend in suicide rates as non-implemented intervention districts. In other words, the suicide rate in the intervention area decreased by 25% following the intervention. These results empirically substantiate suicide prevention programs in primary care clinics by community public health resources for reduced suicide rates to support effective community-based suicide prevention interventions.

The 4-level approach: A community-based intervention targeting depression and suicidal behaviour

Multilevel community-based interventions are considered the most efficient way to target diagnostic and treatment gaps concerning depression and to prevent suicidal behaviour. The 4-level intervention approach of the European Alliance against Depression (EAAD) combines the two partly overlapping aims of improving care for people with depression and preventing suicidal behavior. After forming a local stakeholder network in a certain region and a preparation phase, intervention activities start at four levels: i) Primary health care, ii) General public, iii) Community facilitators, iv) Affected individuals' and their relatives. This 4-level approach has been successfully adapted to different cultures and health care systems in more than 120 regions in and from outside of Europe. A systematic review recently has singled out this 4-level approach as the most promising community-based suicide preventive intervention worldwide. In this paper, the 4-level approach, it´s evidence base, and lessons learnt concerning implementation are presented.

A qualitative exploration of the health needs and goals of urban women to inform the tailoring and adaptation of Strong Hearts Healthy Communities: a community-based cardiovascular disease prevention intervention

BackgroundIn the United States, cardiovascular diseases (CVD) are the leading cause of death and disability in women. CVD-modifiable risk factors, including poor diet quality and inadequate physical activity, can be addressed through evidence-based interventions (EBIs). Strong Hearts Healthy Communities (SHHC) is an EBI that has demonstrated effectiveness in reducing CVD risk and improving health outcomes among rural white women. The aims of this study were to understand the general health, diet, and physical activity-related needs and goals of women living in an urban community, to inform the tailoring and adaptation of the SHHC EBI to an urban setting and more diverse population.MethodsFocus groups (FGs) were conducted with African American/Black and Hispanic/Latinx women in the Dallas metropolitan area who had a BMI ≥ 25 kg/m2 and engaged in ≤ 150 min per week of moderate physical activity. The data were coded using a team-based, deductive, and thematic analysis approach, that included multiple coders and in-depth discussions.ResultsFour FGs with a total of 18 participants (79% Black and 21% Latinx) were conducted, and three themes were developed: (1) participants had adequate knowledge and positive attitudes towards healthy living but faced many barriers to practicing healthy behaviors; (2) culturally-based beliefs and community practices exerted a strong influence on behaviors related to food and stress, revealing barriers to healthy eating and generational differences in stress and stress management; (3) participants desired a more individualized approach to nutrition and physical activity interventions that included familiar and enjoyable activities and social support centered around shared health goals.ConclusionsThe SHHC intervention and similar health programs for Black/African American and Hispanic/Latinx women in urban settings should emphasize individualized nutrition and practical skills for healthy eating with accessible, familiar, and enjoyable exercises. Additionally, stress management strategies should be culturally and generationally sensitive and social support, whether through family, friends, or other program participants, should be based on shared health goals.

Are climate-change actions present in community-based obesity prevention interventions? Development and application of the DoublE-duty actions in CommunIty-baSed obesity InterVEntions (DECISIVE) framework

Abstract Aim Community-based obesity prevention interventions (CBOPIs) target the causes of obesity. Actions implemented in CBOPIs could simultaneously impact both climate change and obesity, making them a potentially important approach. To date, limited work has been undertaken to identify and categorise double-duty actions (those that simultaneously influence obesity and climate change) in CBOPIs. The prevalence of double-duty actions in CBOPIs is currently unknown. This paper outlines the development and application of the DoublE-duty actions in CommunIty-baSed obesity InterVEntions (DECISIVE) framework to address this gap. Subjects and methods A scoping review focusing on obesity and climate change was performed, and the results informed the development of DECISIVE. DECISIVE was applied to studies included in the Cochrane review of obesity prevention interventions in children, and both the published and unpublished data of a completed intervention. Results The scoping review identified one study and one systematic review which contributed to the development of DECISIVE. The framework lists nine double-duty actions, plus an ‘Other’ action. Each action’s potential impact on both obesity and climate change is summarised and example strategies are provided. Reduce the availability and consumption of ultra-processed foods was the most prevalent double-duty action when applying DECISIVE to published studies. Conclusion DECISIVE is the first framework to recognise double-duty actions on obesity and climate change in CBOPIs. The development of DECISIVE holds important implications for community stakeholders who may be able to better identify, incorporate, and promote double-duty actions. This may enhance stakeholder acceptability, feasibility, and value-for-money of interventions.

Urban-rural differences in seasonal malaria chemoprevention coverage and characteristics of target populations in nine states of Nigeria: a comparative cross-sectional study.

Differences between urban and rural contexts in terms of sociodemographic characteristics, geographical features and risk perceptions may lead to disparities in coverage and related outcomes of community-based preventive interventions, such as seasonal malaria chemoprevention (SMC). This study investigated urban-rural differences in SMC coverage and other programme outcomes, as well as child and caregiver characteristics of target populations in nine implementing states in Nigeria during the 2022 SMC round. This is a comparative cross-sectional study based on comprehensive end-of-round household surveys conducted in nine states where SMC was delivered in Nigeria in 2022. Data of 11,880 caregiver-child pairs were included in the analysis. Rural-urban differences in SMC outcomes and child and caregiver characteristics were assessed, first by using Pearsons' chi-square test for independence for categorical variables. Univariate multilevel mixed-effect logistic regression models, with random intercepts for cluster units, were used to quantify the strength of association between location and each SMC coverage and related outcomes. Significant urban-rural differences were observed in caregivers' sociodemographic characteristics, such as age, gender, level of education, occupation status and health-seeking behaviour for febrile childhood illnesses. Disparities were also seen in terms of SMC coverage and related outcomes, with lower odds of the receipt of Day 1 dose direct observation of the administration of Day 1 dose by community distributors, receipt of the full three-day course of SMC medicines and receipt of SMC in all cycles of the annual round among children residing in urban areas, compared with those residing in rural areas. Similarly, urban-dwelling caregivers had lower odds of being knowledgeable of SMC and believing in the protective effect of SMC than rural-dwelling caregivers. Findings highlight observable urban-rural disparities in SMC programme delivery and related outcomes, as well as target population characteristics, underscoring the need for context-specific strategies to ensure optimal delivery of SMC and improve programme implementation outcomes in urban settings.

Sex Differences in Diet and Physical Activity Behaviors Among Racial/Ethnic Minority Adolescents with High Metabolic Risk.

Certain dietary and physical activity (PA) behaviors may differentially predispose male and female adolescents to obesity and diabetes; however, sex differences in dietary and PA behaviors and in factors that impact these behaviors (e.g., self-efficacy, social support) in this population remain unknown. Using data from a community-based adolescent diabetes prevention intervention conducted in East Harlem in New York City, we examined sex differences in baseline characteristics including clinical measurements, lifestyle behaviors, and behavioral determinants. Among 147 overweight/obese adolescents aged 13-19years, 61.9% were girls, 69.7% were of Hispanic ethnicity, 24.8% were non-Hispanic Black, and 60.5% were diagnosed with prediabetes. Boys had higher metabolic risk scores than girls (3.8 vs. 3.3, p = 0.002) despite girls reporting more perceived barriers to healthy eating and PA. Boys reported doing more moderate to vigorous PA but also had more sedentary behaviors than girls. Boys reported higher self-efficacy and more peer support for PA. Girls reported more depressive symptoms and were more likely to compare their body images to those in magazines/social media. Overall, among a sample of urban adolescents with high metabolic risk, we found significant sex differences in many dietary and PA behaviors and related factors, which could be used to inform tailored strategies for weight management to reduce cardiometabolic risk among youth from similar high-risk populations.

BRINGING COMMUNITY-BASED FALLS PREVENTION PROGRAM TO IMPROVE GLOBAL HEALTH (BRIGHT)

Abstract Older adults in low- and middle-income countries (LMICs) experience a disparate burden of non-communicable diseases (NCDs) and barriers to accessing health care. Unintentional injuries are among the major NCDs, and falls are the second leading cause of these injuries and deaths. Falls were reported in up to 50% of older people living in Asia, including Thailand. There is a lack of community-based multifactorial fall prevention interventions that target both older adults and the primary care systems. We aimed to culturally adapt the CDC’s Stopping Elderly Accidents, Deaths, and Injuries (STEADI) for Thai older adults and explore the feasibility, appropriateness, and acceptability of using STEADI by trained community health workers (CHWs) and care managers (CMs). STEADI consists of three steps: screening, assessing, and intervening. In Step a, CHWs screened fall risk using three key questions and found that all of participants had fall risk, then CHWs screened with a Stay Independent questionnaire (range 0-14) and found that 100% have high fall risk (total scores 9.7± 2.4). In Step b, CMs assessed risk factors and CHWs assessed home hazards. They found that 50% had poor balance, 70% took 4+ medications, 75% fell on the walkway, and 70% had no bathroom modifications. In Step c, individual participants received fall prevention interventions and participants attended all sessions. Our results indicated that STEADI delivered by CHWs and CMs is feasible and acceptable for older adults. The mean scores of acceptability, appropriateness, and feasibility were 19.20,18.80, and 18.60 out of 20 totals, respectively.

Abstract A027: Creating partnerships to deliver community-based interventions for cancer prevention in a historically African American community

Abstract Be Well Communities™ is MD Anderson’s signature place-based approach for cancer prevention and control, working with communities to promote wellness and address modifiable risk factors for cancer. In this project, the planning phase of the Be Well Communities’ model was implemented in Acres Homes, a neighborhood in northwest Houston with more than 57,000 residents. While the changing demographics show increasing numbers of residents of Hispanic descent (43% of the population), Acres Homes still experiences effects of a legacy of Blacks experiencing poverty; more than half of the population of Acres Homes resides in census tracts that are considered areas of persistent poverty. Further, it is a medically underserved area with relatively high rates of unhealthy behaviors, as compared to Healthy People 2030 goals. To work toward addressing the disparities in health outcomes experienced by community residents, a community advisory group (Steering Committee) including residents, non-profit organizations, health care partners, city and county agencies, plus other stakeholders, was convened and aligned through a structured process to develop shared goals, foster multisector collaboration (as measured by a stakeholder survey administered twice), and enhance community capacity to improve health outcomes through development of a Community Action Plan. Clear, achievable goals were developed, multisector collaboration was enhanced, and more than 400 hours of capacity building support led to a Community Action Plan focused on healthy eating and active living, including 15 evidence-based interventions led by 18 organizations. The majority (93%) of the Steering Committee reports that this plan reflects community priorities and will reach the residents most in need. In the first 2 years of implementation nearly 40% of the residents of the community have been reached by programs including more than 5,000 residents participating in physical activity opportunities, classes and over 1000 individuals receiving outreach from a Community Health Worker within the safety-net hospital system to receive access to healthy food access and nutrition education programming. By listening and developing trust, the Be Well Communities team successfully worked with Acres Homes residents and organizations to enhance community capacity to address health inequities in one of Houston’s most historic communities.

A mixed-methods evaluation of the acceptability and fidelity of the James’ Place model for men experiencing suicidal crisis

ABSTRACT Background Research supports development of informal, community-based suicide prevention interventions that can be tailored to suit men’s unmet needs. The James’ Place model (JPM) is a community-based, clinical suicide prevention intervention for men experiencing suicidal crisis. Evidence supports the efficacy of the JPM and there are plans to expand to additional sites across the UK. This study evaluates therapists perceived acceptability of the JPM, and if fidelity to the planned delivery of the model is maintained within therapeutic practice. Method A mixed-methods design was used. Descriptive analyses of 30 completed intervention cases were examined to review fidelity of the model against the intervention delivery plan. Eight therapists took part in semi-structured interviews between November 2021 and March 2022 exploring the perceived acceptability, and barriers and facilitators to delivering the JPM. Results Descriptive analyses of James’ Place audit notes revealed high levels of adherence to the JPM amongst therapists, but highlighted components of the model needed to be tailored according to individual men’s needs. Thematic analysis led to the development of five themes. The first theme, therapeutic environment highlighted importance of the therapy setting. The second theme identified was specialised suicide prevention training in the JPM that facilitated therapists understanding and expertise. The third theme identified was therapy engagement which discusses men’s engagement in therapy. The fourth theme, person-centred care related to adaptation of delivery of JPM components. The final theme, adapting the JPM to individual needs describes tailoring of the JPM by therapists to be responsive to individual men’s needs. Conclusion The findings evidence therapist’s acceptability and their moderate adherence to the JPM. Flexibility in delivery of the JPM enables adaptation of the model and co-production of therapy to meet men’s needs. Implications for clinical practice are discussed.

Types, reporting and acceptability of community-based interventions for stillbirth prevention in sub-Saharan Africa (SSA): a systematic review

Community-based interventions are increasingly being implemented in Sub-Saharan Africa (SSA) for stillbirth prevention, but the nature of these interventions, their reporting and acceptability are poorly assessed. In addition to understanding their effectiveness, complete reporting of the methods, results and intervention acceptability is essential as it could potentially reduce research waste from replication of inadequately implemented and unacceptable interventions. We conducted a systematic review to investigate these aspects of community-based interventions for preventing stillbirths in SSA. In this systematic review, eight databases (MEDLINE(OvidSP), Embase (OvidSP), Cochrane Central Register of Controlled Trials, Global Health, Science Citation Index and Social Science Citation index (Web of Science Core Collection), CINAHL (EBSCOhost) and Global Index Medicus) and four grey literature sources were searched from January 1, 2000 to July 7, 2023 for relevant quantitative and qualitative studies from SSA (PROSPERO-CRD42021296623). Following deduplication, abstract screening and full-text review, studies were included if the interventions were community-based with or without a health facility component. The main outcomes were types of community-based interventions, completeness of intervention reporting using the TIDier (Template for Intervention Description and replication) checklist, and themes related to intervention acceptability identified using a theoretical framework. Study quality was assessed using the Cochrane risk of bias and National Heart, Lung and Blood Institute's tools. Thirty-nine reports from thirty-four studies conducted in 18 SSA countries were eligible for inclusion. Four types of interventions were identified: nutritional, infection prevention, access to skilled childbirth attendants and health knowledge/behaviour of women. These interventions were implemented using nine strategies: mHealth (defined as the use of mobile and wireless technologies to support the achievement of health objectives), women's groups, community midwifery, home visits, mass media sensitisation, traditional birth attendant and community volunteer training, community mobilisation and transport vouchers. The completeness of reporting using the TIDier checklist varied across studies with a very low proportion of the included studies reporting the intervention intensity, dosing, tailoring and modification. The quality of the included studies were graded as poor (n=6), fair (n=14) and good (n=18). Though interventions were acceptable, only 4 (out of 7) studies explored women's perceptions, mostly focusing on perceived intervention effects and how they felt, omitting key constructs like ethicality, opportunity cost and burden of participation. Different community-based interventions have been tried and evaluated for stillbirth prevention in SSA. The reproducibility and implementation scale-up of these interventions may be limited by incomplete intervention descriptions in the published literature. To strengthen impact, it is crucial to holistically explore the acceptability of these interventions among women and their families. Clarendon/Balliol/NDPH DPhil scholarship for UGA.

The Pre-Implementation Phase of a Project Seeking to Deliver a Community-Based CVD Prevention Intervention (SPICES-Sussex): A Qualitative Study Exploring Views and Experience Relating to Intervention Development.

Community-led health care interventions may be an effective way to tackle cardiovascular disease (CVD) risk factors, especially in materially deprived communities where health care resources are stretched and engagement with institutions is often low. To do so effectively and equitably, interventions might be developed alongside community members through community engagement. The aim of this project was to carry out stakeholder mapping and partnership identification and to understand the views, needs, experiences of community members who would be involved in later stages of a community-based CVD prevention intervention's development and implementation. Stakeholder mapping was carried out to identify research participants in three communities in Sussex, United Kingdom. A qualitative descriptive approach was taken during the analysis of focus groups and interviews with 47 participants. Three themes were highlighted related to intervention design (a) Management: the suitability of the intervention for the community, management of volunteers, and communication; (b) Logistics: the structure and design of the intervention; and (c) Sociocultural issues, the social and cultural expectations/experiences of participants and implementers. Study participants were open and willing to engage in the planned community-based intervention, particularly in elements of co-design and community-led delivery. They also highlighted the importance of sociocultural factors. Based on the findings, we developed recommendations for intervention design which included (but were not limited to): (a) a focus on a bottom-up approach to intervention design, (b) the recruitment of skilled local volunteers, and (c) the importance of fun and simplicity.

Dietary outcomes of community-based cardiovascular disease preventive interventions: a systematic review and meta-analysis.

We aimed to synthesize available evidence on the effects of community-based interventions in improving various dietary outcome measures. Systematic review and meta-analysis. We searched databases including Medline, EMBASE, PSYCINFO, CINAHL, and the Cochrane registry for studies reported between January 2000 and June 2022. The methodological quality of the included studies was evaluated using the Cochrane risk of bias tools for each study type. For some of the outcomes, we pooled the effect size using a random-effects meta-analysis. A total of 51 studies, 33 randomized and 18 non-randomized, involving 100 746 participants were included. Overall, 37 studies found a statistically significant difference in at least one dietary outcome measure favoring the intervention group, whereas 14 studies found no statistically significant difference. Our meta-analyses indicated that, compared to controls, interventions were effective in decreasing daily energy intake (MJ/day) (MD: -0.25; 95% CI: -0.37, -0.14), fat % of energy (MD: -1.01; 95% CI: -1.76, -0.25), and saturated fat % of energy (MD: -1.54; 95% CI: -2.01, -1.07). Furthermore, the interventions were effective in improving fiber intake (g/day) (MD: 1.08; 95% CI: 0.39, 1.77). Effective interventions use various strategies including tailored individual lifestyle coaching, health education, health promotion activities, community engagement activities and/or structural changes. This review shows the potential of improving dietary patterns through community-based CVD preventive interventions. Thus, development and implementation of context-specific preventive interventions could help to minimize dietary risk factors, which in turn decrease morbidity and mortality due to CVDs and other non-communicable diseases.

A novel method for measuring the burden of breast cancer in neighborhoods

Community-based breast cancer prevention efforts often focus on women who live in the same neighborhoods, as they tend to have similar demographic characteristics, health behaviors, and environmental exposures; yet little research describes methods of selecting neighborhoods of focus for community-based cancer prevention interventions. Studies frequently use demographics from census data, or single breast cancer outcomes (e.g., mortality, morbidity) in order to choose neighborhoods of focus for breast cancer interventions, which may not be optimal. This study presents a novel method for measuring the burden of breast cancer among neighborhoods that could be used for selecting neighborhoods of focus. In this study, we 1) calculate a metric composed of multiple breast cancer outcomes to describe the burden of breast cancer in census tracts Philadelphia, PA, USA; 2) map the neighborhoods with the greatest breast cancer burden; and 3) compare census tracts with the highest burden of breast cancer to those with demographics sometimes used for geo-based prioritization, i.e., race and income. The results of our study showed that race or income may not be appropriate proxies for neighborhood breast cancer burden; comparing the breast cancer burden with demographics at the census tract level, we found few overlaps with the highest percentage African American or the lowest median incomes. Agencies implementing community-based breast cancer interventions should consider this method to inform the selection of neighborhoods for breast cancer prevention interventions, including education, screening, and treatment.

Effects of a ‘social activity program that encourages interaction’ on rural older people's psychosocial health: Mixed‐methods research

We developed a program that encourages interaction among older people living at home by combining face-to-face and online activities and examined its effects on older adults' psychosocial health. In this mixed-methods study, we recruited 11 women and 6 men (Mage=79.5 ± 6.4 years), who lived in a rural community and participated in a senior citizen club. The intervention was conducted for 13months, comprising monthly face-to-face group and social media activities. For the program process evaluation, we collected focus-group interview data on participants' perceptions of their personal lives, club membership, and community post-intervention. For the outcome evaluation, we collected six outcome measures pre- and post-intervention: loneliness, subjective health, subjective well-being, self-esteem, social support and social activity satisfaction. Finally, through the integration of the process-outcome evaluation, we inferred what effects the program had on participants' psychosocial health. In the process evaluation, we identified four themes: 'Stimulation brought about by relationships with peers,' 'Realization as to where they feel they belong,' 'Rethinking of oneself in the community,' and 'Awareness of attachment to and coexistence with the community.' In the outcome evaluation, the outcome measures were maintained without significant decline post-intervention. Through the integration of the process-outcome evaluation, we deduced three effects of the program on psychosocial health: (1) fulfilment of subjective health, (2) maintenance and assurance of moderate distance connectedness and (3) orientation toward aging in place. This study offers a promising opportunity for further development and research into community-based preventive nursing care intervention strategies to maintain the psychosocial health of homebound older people in communities with social activity groups.

Reducing inequities in maternal and child health in rural Guatemala through the CBIO+ Approach of Curamericas: 5. Mortality assessment

BackgroundThe Curamericas/Guatemala Maternal and Child Health Project, 2011–2015, implemented the Census-Based, Impact-Oriented Approach, the Care Group Approach, and the Community Birthing Center Approach. Together, this expanded set of approaches is known as CBIO+. This is the fifth of 10 papers in our supplement describing the Project and the effectiveness of the CBIO+ Approach. This paper assesses causes, levels, and risk factors for mortality along with changes in mortality.MethodsThe Project maintained Vital Events Registers and conducted verbal autopsies for all deaths of women of reproductive age and under-5 children. Mortality rates and causes of death were derived from these data. To increase the robustness of our findings, we also indirectly estimated mortality decline using the Lives Saved Tool (LiST).FindingsThe leading causes of maternal and under-5 mortality were postpartum hemorrhage and pneumonia, respectively. Home births were associated with an eight-fold increased risk of both maternal (p = 0.01) and neonatal (p = 0.00) mortality. The analysis of vital events data indicated that maternal mortality declined from 632 deaths per 100,000 live births in Years 1 and 2 to 257 deaths per 100,000 live birth in Years 3 and 4, a decline of 59.1%. The vital events data revealed no observable decline in neonatal or under-5 mortality. However, the 12–59-month mortality rate declined from 9 deaths per 1000 live births in the first three years of the Project to 2 deaths per 1000 live births in the final year. The LiST model estimated a net decline of 12, 5, and 22% for maternal, neonatal and under-5 mortality, respectively.ConclusionThe baseline maternal mortality ratio is one of the highest in the Western hemisphere. There is strong evidence of a decline in maternal mortality in the Project Area. The evidence of a decline in neonatal and under-5 mortality is less robust. Childhood pneumonia and neonatal conditions were the leading causes of under-5 mortality. Expanding access to evidence-based community-based interventions for (1) prevention of postpartum hemorrhage, (2) home-based neonatal care, and (3) management of childhood pneumonia could help further reduce mortality in the Project Area and in similar areas of Guatemala and beyond.

Demographic and HIV status diversities as mechanisms of social integration and segregation among Black sexual and gender minorities enrolled in a community-based social network intervention

Drawing on a social integration and intersectionality framework, this study advances a dynamic network understanding of the mechanisms that enable differential patterns of within-group social integration and segregation among Black sexual and gender minorities (BSGM). Specifically, in a cohort of BSGM (18–35 years of age, n = 340) participating in a community-based network intervention for HIV prevention, we examine how sexual, gender, age, and HIV status diversities contribute to friendship formation and maintenance patterns over the 12-month study enrollment period. We found attenuated social integration (or social activity) among non-gay-identified and older BSGM and evidence of social segregation (or homophily) on the basis of sexual identity and age similarities. Accounting for the moderating effects of the intervention revealed that the attenuated integration of non-gay-identified and older BSGM were stronger for participants who received the peer leadership training, and integration challenges were also found for transgender BSGM who received the peer leadership training. Meanwhile, BSGM living with HIV who received the peer leadership training were significantly more integrated than their counterparts in the control arm. These findings help us understand the complicated social fabric among BSGM and the dynamics that interventions for this community may have to contend with or alter.

Primary headache disorders in Latin America and the Caribbean: A meta-analysis of population-based studies

In this manuscript, we aim to systematically estimate the pooled prevalence and incidence of primary headaches and its subtypes (migraine, tension-type headache, and chronic headaches) in Latin America and the Caribbean, describing its epidemiological profile and associated factors. We systematically searched PubMed/MEDLINE, Scopus, and LILACS (From conception to March 2021), for populational studies reporting the epidemiology of primary headaches and their associated factors in Latin America and the Caribbean. The data extraction was conducted independently. We performed random-effect model meta-analysis of prevalence (overall primary headaches and by subtypes) and associated factors, assessed potential sources of heterogeneity, the risk of bias, publication bias, and the evidence certainty (GRADE methodology). We included 32 populational studies (38 subpopulations, n = 63,813). The prevalence of primary headaches was 41.4% (95% CI 31.1-52.2%; n = 54,357), 15% for migraine (95% CI 12.0-18.3; n = 53,658 individuals), 20.6% for tension-type headache (95% CI 12.4-30.2; n = 25,840), and 6% for chronic headaches (95% CI 3.3-9.6; n = 21,720), with high between-study heterogeneity. No incidence data was found. Female sex, white ethnicity, high BMI, comorbid mental health disorders, and low-back pain were associated with higher prevalence of primary headaches. The prevalence was less in rural areas. In Latin America and the Caribbean, primary headaches are highly prevalent affecting young females disproportionally. The prevalence of chronic headaches is higher than in other systematic global and regional estimations. The presence of comorbidities as modifiable risk factors should encourage their integration as targets for community-based preventive and therapeutic interventions. CRD42018105116.

Effects of a community-based substance use prevention program in Iranian adolescents (SUPPIA)-using social cognitive theory

ABSTRACT Objective This study aimed to develop and assess a tailored community-based intervention protocol for preventing substance use based on social cognitive theory in adolescents. Methods A tailored community-based substance use prevention intervention was undertaken with 140 boys and girls (14-18- years old) participating in the study in Isfahan, Iran. The intervention group attended eight 45-minute theory-based sessions based on social cognitive theory from 2018 to 2020. Data were analyzed 6, 18, and 24 months later by the SPSS.23 software. Results Social cognitive theory indicators, including positive outcome expectancies (p < .001, F = 25, ES = 0.34), negative outcomes expectancies (p < .001, F = 31.2, ES = 0.38), and self-efficacy (p < .001, F = 12.3, ES = 0.45) showed significant improvements at three stages (6, 18, and 24 months after intervention). The program also demonstrated significant but low effect size reductions in the incidence of cigarette (ES = 0.15), alcohol (ES = 0.05), and other drug use (ES = 0.01) in the intervention group among three follow-ups. Conclusion The results support the effectiveness of the community-based intervention program based on social cognitive theory in reducing the incidence of substance use among Iranian adolescents.

Pilot Study of a Fall Prevention and Management Intervention Program for People With Multiple Sclerosis Who Use a Wheelchair or Scooter Full-Time

To examine the efficacy of a fall prevention/management intervention among persons with multiple sclerosis (PwMS) who use a wheelchair (WC) or scooter full-time. Pre-post/follow-up trial. Community and research laboratory. Twenty-one PwMS who used a WC or scooter full-time, self-reported at least 1 fall/12 months, and could transfer independently or with minimal/moderate assistance (N=21). Six-week, group and community-based fall prevention and management intervention. The intervention included six 2-hour in-person weekly sessions led by a physical or occupational therapist featuring interactive group discussions, skill practice, and action planning opportunities. Fall frequency tracked 12 weeks pre- and 24 weeks post intervention. Outcomes were assessed pre- and post intervention and 12 weeks post intervention. Measures included surveys to examine fear of falling (FOF), fall prevention/management, quality of life, community participation, and assessment of functional mobility skills. Semistructured interviews were administered post intervention to ascertain overall experiences with the program and effect on daily life. A Friedman test with signed-rank post hoc analysis was run to determine differences across the 3 study visits. After the intervention, fall incidence did not significantly change, but fall management strategies (P=.01-0.05), importance of community participation (P=.01), and transfer quality (P=.02) significantly improved. Moderate effect sizes were noted among concerns about falling, activity curtailment because of to FOF, and WC skills. Qualitative results indicate that participants found the intervention beneficial and applied intervention content in their daily lives. This study is the first to describe the effect of a multicomponent fall prevention/management intervention designed specifically for PwMS who use a WC or scooter full-time. Results indicate the program has potential to reduce fall risk; however, further testing is needed to fully examine the effect of the program.
