Collective efficacy and obesity-related health behaviors in a community sample of African Americans

Pediatric obesity during COVID-19: the role of neighborhood social vulnerability and collective efficacy

INTRODUCTION

Childhood obesity increased in the first year of COVID-19 with significant disparities across race, ethnicity, and socioeconomic status. Social distancing led to fewer physical activity opportunities but increased screen time and high-calorie food consumption, all co-determined by neighborhood environments. This study aimed to test the moderation effects of neighborhood socioeconomic and built environments on obesity change during COVID-19.

METHODS

Using electronic health records from a large pediatric primary care network in 2018-2022, we cross-sectionally examined 163,042 well visits of 2-17-year-olds living in Philadelphia County in order to examine (1) the pandemic's effect on obesity prevalence and (2) moderation by census-tract-level neighborhood socioeconomic disadvantage, crime, food and physical activity-related environments using interrupted-time-series analysis, Poisson regression, and logistic regression.

RESULTS

Weekly obesity prevalence increased by 4.9 percent points (pp) during the pandemic (January 2021-August 2022) compared to pre-pandemic (March 2018-March 2020) levels. This increase was pronounced across all age groups, racially/ethnically minoritized groups, and insurance types (ranging from 2.0 to 6.4 pp) except the Non-Hispanic-white group. The increase in obesity among children racially/ethnically minoritized groups was significantly larger in the neighborhoods with high social vulnerability (3.3 pp difference between high and low groups), and low collective efficacy (2.0 pp difference between high and low groups) after adjusting for age, sex, and insurance type.

CONCLUSIONS

Racially/ethnically minoritized children experienced larger obesity increases during the pandemic, especially those in socioeconomically disadvantaged neighborhoods. However, the buffering effect of community collective efficacy on the disparities underscores the importance of environments in pediatric health.

Qualitative Insights on the Importance of Sociocultural Contexts on Asian Indian Migrant Participation in Physical Activity and Sedentary Behavior

BACKGROUND

Influences on physical activity and sedentary behavior may differ for migrants moving from their country of origin to a new country. This study aimed to explore the range of contextual factors that influence physical activity and sedentary behavior among Indian migrants, making comparisons with India.

METHODS

Semistructured interviews were conducted with 21 Indian migrants (10 men and 11 women) aged between 18 and 65 years living in Melbourne, Australia. Data were analyzed thematically, coded inductively, and managed with NVivo.

RESULTS

Participants perceived a lack of social connection as a key barrier to physical activity participation. Group-based physical activity fostered social connections. Cultural associations were sites to engage in cultural physical activity and integrate with other Indians. Australia's physical contexts (eg, availability of facilities and built environment) facilitated physical activity behavior. Workplace environments (eg, the nature of the job) prompted sedentary behavior. Other contextual shifts with migration related to activities of daily living (eg, shifts in transport [walking] behavior in India to a greater reliance on cars in Australia) and migrant-friendly health communication (messaging from Australian health/allied health practitioners).

CONCLUSIONS

Sociocultural contexts remain key influences on migrant physical activity participation. Prioritizing integrated approaches and engaging insider codesign are important in tailoring and promoting migrant physical activity and limiting sedentary behavior.

Disparities in pediatric obesity during COVID-19: The role of neighborhood social vulnerability and collective efficacy

Introduction

Childhood obesity increased in the first year of Covid-19 with significant disparities across race, ethnicity, and socioeconomic status. Social distancing led to fewer physical activity opportunities but increased screen time and high-calorie food consumption, all co-determined by neighborhood environments. This study aimed to test the moderation effects of neighborhood socioeconomic and built environments on racial/ethnic disparities in obesity change during Covid-19.

Racially/ethnically-minoritized children experienced larger obesity increases during the pandemic, especially those in socioeconomically disadvantaged neighborhoods. However, the buffering effect of community collective efficacy on the disparities underscores the importance of environments in pediatric health.

The Growing Role of Technology in the Care of Older Adults With Diabetes

The integration of technologies such as continuous glucose monitors, insulin pumps, and smart pens into diabetes management has the potential to support the transformation of health care services that provide a higher quality of diabetes care, lower costs and administrative burdens, and greater empowerment for people with diabetes and their caregivers. Among people with diabetes, older adults are a distinct subpopulation in terms of their clinical heterogeneity, care priorities, and technology integration. The scientific evidence and clinical experience with these technologies among older adults are growing but are still modest. In this review, we describe the current knowledge regarding the impact of technology in older adults with diabetes, identify major barriers to the use of existing and emerging technologies, describe areas of care that could be optimized by technology, and identify areas for future research to fulfill the potential promise of evidence-based technology integrated into care for this important population.

Effects of social media empowerment on COVID-19 preventive behaviors in China

Purpose

During the coronavirus disease 2019 (COVID-19) pandemic, ubiquitous social media has become a primary channel for information dissemination, social interactions and recreational activities. However, it remains unclear how social media usage influences nonpharmaceutical preventive behavior of individuals in response to the pandemic. This paper aims to explore the impacts of social media on COVID-19 preventive behaviors based on the theoretical lens of empowerment.

Design/methodology/approach

In this paper, survey data has been collected from 739 social media users in China to conduct structural equation modeling (SEM) analysis.

Findings

The results indicate that social media empowers individuals in terms of knowledge seeking, knowledge sharing, socializing and entertainment to promote preventive behaviors at the individual level by increasing each person's perception of collective efficacy and social cohesion. Meanwhile, social cohesion negatively impacts the relationship between collective efficacy and individual preventive behavior.

Originality/value

This study provides insights regarding the role of social media in crisis response and examines the role of collective beliefs in the influencing mechanism of social media. The results presented herein can be used to guide government agencies seeking to control the COVID-19 pandemic.

Neighborhood level facilitators and barriers to hypertension management: A Native Hawaiian perspective

Native Hawaiians have a disproportionately high prevalence of hypertension, which is an important and modifiable risk factor for cardiovascular disease (CVD). To reduce CVD among Native Hawaiians, we must better understand facilitators and barriers to hypertension management (i.e., diet, physical activity, stress reduction) unique to Native Hawaiians. Despite evidence of neighborhood-level facilitators and barriers to hypertension management in other populations, there is limited research in Native Hawaiians. Participants from a randomized controlled trial (n = 40) were recruited for 5 focus groups. All participants were self-reported Native Hawaiians and had uncontrolled hypertension. Discussions elicited experiences and perceptions of neighborhood-level stressors as they relate to participants' hypertension management efforts. Audio recordings were transcribed and analyzed using ATLAS.ti for emergent themes. Five themes were identified: neighborhood description, community resources, neighborhood change, safety, and social connectedness. Novel barriers to hypertension control included loss of culture and loss of respect for elders, change in community feel, and over-development. Facilitators included social cohesion and collective power. These data provide a deeper understanding of how Native Hawaiians experience neighborhood factors and how those factors impact their efforts to improve their diets, physical activity, and stress management. The findings help to inform the development of multilevel CVD prevention programs. Further research is needed to explore the subtheme of social and emotional stress related to neighborhood change and CVD health risk due to cultural and historic trauma references.

Neighborhood social organization exposures and racial/ethnic disparities in hypertension risk in Los Angeles

Despite a growing evidence base documenting associations between neighborhood characteristics and the risk of developing high blood pressure, little work has established the role played by neighborhood social organization exposures in racial/ethnic disparities in hypertension risk. There is also ambiguity around prior estimates of neighborhood effects on hypertension prevalence, given the lack of attention paid to individuals' exposures to both residential and nonresidential spaces. This study contributes to the neighborhoods and hypertension literature by using novel longitudinal data from the Los Angeles Family and Neighborhood Survey to construct exposure-weighted measures of neighborhood social organization characteristics-organizational participation and collective efficacy-and examine their associations with hypertension risk, as well as their relative contributions to racial/ethnic differences in hypertension. We also assess whether the hypertension effects of neighborhood social organization vary across our sample of Black, Latino, and White adults. Results from random effects logistic regression models indicate that adults living in neighborhoods where people are highly active in informal and formal organizations have a lower probability of being hypertensive. This protective effect of exposure to neighborhood organizational participation is also significantly stronger for Black adults than Latino and White adults, such that, at high levels of neighborhood organizational participation, the observed Black-White and Black-Latino hypertension differences are substantially reduced to nonsignificance. Nonlinear decomposition results also indicate that almost one-fifth of the Black-White hypertension gap can be explained by differential exposures to neighborhood social organization.

Associations of Neighborhood Safety and Collective Efficacy with Dietary Intake among Preschool-Aged Children and Mothers

Background: Positive neighborhood environments may promote healthier behaviors, yet few studies have examined associations between neighborhood social environment and diet. We examined associations of neighborhood perceived safety, collective efficacy, and violent crime with dietary intake among preschool-aged children and their mothers. Methods: We administered a cross-sectional survey to 300 mothers/female caregivers of Medicaid-enrolled 2- to 4-year-old children in Philadelphia. Mothers reported their own and their child's dietary intake using the validated Dietary Screener Questionnaire. Mixed-effects linear regression models assessed associations of perceived neighborhood safety, collective efficacy, and census tract-level violent crime with parent and child dietary intake, adjusted for individual, family, and neighborhood covariates. Results: Among mothers, higher perceived neighborhood safety and collective efficacy were associated with higher daily intake of fruits/vegetables (β = 0.35 cups, 95% CI: 0.12-0.58 and β = 0.30 cups, 95% CI: 0.08-0.52, comparing the highest with lowest tertile). Higher neighborhood-perceived safety was also associated with higher whole-grain intake among mothers (β = 0.14 ounces, 95% CI: 0.02-0.27) and children (β = 0.07 ounces, 95% CI: 0.01-0.13, comparing the highest with lowest tertile). Neighborhood social exposures were not associated with intake of added sugars or sugar-sweetened beverages for mothers or children, nor were lower levels of violent crime associated with any outcome. Conclusions: More favorable perceptions of neighborhood safety and collective efficacy were associated with a slightly higher consumption of some healthy foods among mothers and their young children. Future prospective research is needed to confirm these findings, explore potential mechanisms, and determine whether intervening on the social environment improves diet.

What Are the Relationships between Psychosocial Community Characteristics and Dietary Behaviors in a Racially/Ethnically Diverse Urban Population in Los Angeles County?

To address existing gaps in public health practice, we used data from a 2014 internet panel survey of 954 Los Angeles County adults to investigate the relationships between psychosocial community characteristics (PCCs) and two key chronic disease-related dietary behaviors: fruit and vegetable (F+V) and soda consumption. Negative binomial regression models estimated the associations between 'neighborhood risks and resources' and 'sense of community' factors for each dietary outcome of interest. While high perceived neighborhood violence (p < 0.001) and perceived community-level collective efficacy (p < 0.001) were associated with higher F+V consumption, no PCCs were directly associated with soda consumption overall. However, moderation analyses by race/ethnicity showed a more varied pattern. High perceived violence was associated with lower F+V consumption among White and Asian/Native Hawaiian/Other Pacific Islander (ANHOPI) groups (p < 0.01). Inadequate park access and walking as the primary mode of transportation to the grocery store were associated with higher soda consumption among the ANHOPI group only (p < 0.05). Study findings suggest that current and future chronic disease prevention efforts should consider how social and psychological dynamics of communities influence dietary behaviors, especially among racially/ethnically diverse groups in urban settings. Intervention design and implementation planning could benefit from and be optimized based on these considerations.

Mediating roles of psychological factors and physical and social environments between socioeconomic status and dietary behaviors among African Americans with overweight or obesity

The study aim was to examine the relationship between socioeconomic status (SES) and dietary behaviors through psychological and environmental mediators among African Americans with overweight or obesity. We conducted a cross-sectional study in 225 African American men and women. Data were analyzed using structural equation modeling with bootstrapping procedures. In the multiple mediation model, SES had a significant indirect effect on dietary behaviors through psychological and environmental factors (β = -.27; p = .01; 95% confidence interval [CI] = -0.59--0.10), but it had no significant direct effect on dietary behaviors (β = .06; p = .70; 95% CI = -0.21-0.39). SES had significant direct effects on psychological (β = .52; p = .01; 95% CI = 0.31-0.77) and environmental factors (β = -.40; p = .03; 95% CI = -0.53--0.25). Psychological (β = -.31; p = .02; 95% CI = -0.68--0.04) and environmental factors (β = .26; p = .01; 95% CI = 0.04-0.47) also showed significant direct effects on dietary behaviors. Thus, psychological and environmental factors mediated the relationship between SES and dietary behaviors in African Americans with overweight or obesity. Interventions that enhance psychological and environmental factors such as self-efficacy, perceived barriers to healthy eating, health perceptions, and physical and social environments may improve dietary behaviors among socioeconomically disadvantaged African Americans.

Social Determinants of Racial Disparities in Breast Cancer Mortality Among Black and White Women

INTRODUCTION

Mortality from breast cancer among Black women is 60% greater than that of White women in South Carolina (SC). The aim of this study was to assess racial differences in mortality among Black and White breast cancer patients based on variations in social determinants and access to state-based early detection programs.

METHODS

We obtained a retrospective record for breast cancer patients diagnosed between 2002 and 2010 from the SC Central Cancer Registry. Mortality was the main outcome while race-stratified Cox proportional hazard models were performed to assess disparities in mortality. We assessed effect modification, and we used an automated backward elimination process to obtain the best fitting models.

RESULTS

There were 3286 patients of which the majority were White women (2186, 66.52%). Compared with married White women, the adjusted hazard ratio (aHR) for mortality was greatest among Black unmarried women (aHR 2.31, CI 1.83, 2.91). Compared with White women who lived in the Low Country region mortality was greatest among Black women who lived in the Midland (aHR 2.17 CI 1.47, 3.21) and Upstate (aHR 2.96 CI 1.96, 2.49). Mortality was higher among Black women that were not receiving services in the Best Chance Network (BCN) program (aHR 1.70, CI 1.40, 2.04) compared with White women.

CONCLUSIONS

To reduce the racial disparity gap in survival in SC, Black breast cancer patients who live in the Upstate, are unmarried, and those that are not enrolled in the BCN program may benefit from more intense navigation efforts directed at early detection and linkage to breast cancer treatments.

Social and clinical determinants of physical activity in prostate cancer survivors

PURPOSE

Physical activity is important for enhancing quality of life and cancer control among prostate cancer survivors. The purpose of this study was to characterize adherence to physical activity guidelines among African American and white prostate cancer survivors based on social and clinical determinants and psychosocial factors.

METHODS

Observational study of meeting guidelines for moderate intensity physical activity in a retrospective cohort of African American and white prostate cancer survivors (n = 89).

RESULTS

Thirty-four percent of survivors met the recommended guidelines for moderate intensity physical activity. There were no racial differences in physical activity between African American and white prostate cancer survivors; however, the likelihood of meeting guidelines was associated significantly with stage of disease, self-rated health, and perceptions of stress. Survivors who had stage pT2c or higher disease had a significantly reduced likelihood of meeting recommended guidelines for physical activity (OR = 0.27, 95% CI = 0.08, 0.86, p = 0.03). The likelihood of meeting guidelines was also reduced among survivors who rated their health as being the same or worse than before they were diagnosed with prostate cancer (OR = 0.32, 95% CI = 0.11, 0.96, p = 0.04). As perceived stress increased, the likelihood of being physically active according to guidelines also decreased (OR = 0.48, 95% CI = 0.26, 0.89, p = 0.02).

CONCLUSION

The results of this study underscore the need to develop, implement, and evaluate strategies to enhance physical activity among prostate cancer survivors, regardless of their racial background. Complementary and alternative strategies for physical activity may be one strategy for enhancing activity levels and managing stress among prostate cancer survivors.

Greater social cohesion is associated with lower body mass index among African American adults

Obesity remains a public health issue, especially for Blacks (or African Americans). Obesity is thought to reflect a complex interaction of socioenvironmental, biological, and cognitive factors. Yet, insufficient attention has been given to psychosocial factors like social cohesion within the African American community. Using multivariable linear regression, we examined the association between social cohesion, measured by the Social Cohesion and Trust scale, and body mass index (BMI) with cross-sectional data (n = 1467) from a cohort study (2008–2009). Greater social cohesion was associated with lower BMI (b = -0.88; 95% CI: −1.45, −0.32) in an unadjusted model. The association was strengthened after further adjusting for relevant covariates (i.e., individual-level sociodemographic factors, health behaviors, and depressive symptoms) (b = -1.26; 95% CI: −1.94, −0.58). Future research should examine potential mechanisms underlying the association between social cohesion and BMI with longitudinal data. In the meantime, obesity prevention and intervention measures should consider promoting social ties and bonds to lower BMI in African American communities.

Responsibility in healthcare across time and agents

It is unclear whether someone's responsibility for developing a disease or maintaining his or her health should affect what healthcare he or she receives. While this dispute continues, we suggest that, if responsibility is to play a role in healthcare, the concept must be rethought in order to reflect the sense in which many health-related behaviours occur repeatedly over time and are the product of more than one agent. Most philosophical accounts of responsibility are synchronic and individualistic; we indicate here what paying more attention to the diachronic and dyadic aspects of responsibility might involve and what implications this could have for assessments of responsibility for health-related behaviour.

Racial disparities, cancer and response to oxidative stress

At the intersection of genetics, biochemistry and behavioral sciences, there is a largely untapped opportunity to consider how ethnic and racial disparities contribute to individual sensitivity to reactive oxygen species and how these might influence susceptibility to various cancers and/or response to classical cancer treatment regimens that pervasively result in the formation of such chemical species. This chapter begins to explore these connections and builds a platform from which to consider how the disciplines can be strengthened further.

The nexus between health and time use among racially and ethnically diverse women

OBJECTIVES

Ethnic and racial health disparities have been well-documented in the scholarly literature. In recent years, evidence about time spent in physical (in)activity and its relationship to physical and mental health has also emerged. This study assesses if observed ethnic/racial health differences were associated with differences in time use.

DESIGN

Our analyses utilized baseline data from 510 Utah women who enrolled in one of two community-based, participatory research intervention studies between 2012 and 2015. The distinct racial/ethnic groups included African immigrants, African Americans, Latinas, Native Hawaiians/Pacific Islanders, American Indians/Alaskan Natives, and rural White, Non-Latina women. In the baseline survey, respondents reported the typical time they spent in paid employment, television/movie viewing, physical activity, food preparation/clean-up, and sleep. Cluster analysis was used to identify seven distinct patterns of time use within these five activities. We related these time use patterns along with race/ethnicity, socio-demographics, and other potentially contributing health-related factors (e.g. smoking status) to two health outcomes: (1) self-reported health status, and (2) depression.

RESULTS

Our time use clusters revealed heterogeneity by racial/ethnic groups, suggesting that some of the health effects that may have been previously ascribed to group membership should instead be attributed to (un)healthy patterns of time use. In particular, spending too much time in sedentary activities such as watching television/movies and too little time sleeping both linked to poor physical and mental health, independently of racial/ethnic group membership.

CONCLUSIONS

Researchers and policy makers designing culturally sensitive physical activity health-related interventions should consider patterns of time use that are associated with poor health. Programs designed to improve sleep time and reduce sedentary television-viewing time may be as important as interventions designed to increase physical activity time. These broader patterns of time use mediated the relationships between race/ethnicity and physical and mental health for the women in our study.

The Role of Collective Efficacy in Reducing Health Disparities: A Systematic Review

Many improvements in health equity are spearheaded by community collaborations working to change policy and social norms. But how can collective efficacy (CE), defined as the willingness and ability of a group to work toward a common good, be increased? Eight articles reporting on interventions aiming to reduce health disparities by improving CE were found for this systematic literature review. All studies showed improvements in CE and most found reduction in disparities, but operationalization of CE varied. Findings support a model of how CE can address health disparities, which can guide standardization of CE interventions and measures.

Technology as a Means to Address Disparities in Mental Health Research: A Guide to "Tele-Tailoring" your Research Methods

We must include rural participants in health-related research if we are to address health-related disparities and inequity, particularly in mental health. However, the first step of the research process, in person, witnessed, signed informed consent is often a limiting factor and insurmountable barrier to precisely the type of research (e.g., telehealth) designed to overcome barriers of geographic distance and travel time. Telehealth, or the provision of medical care or services to patients by means of audio/video and procedure-specific technology, addresses some barriers to health created by rurality by making health care professionals more accessible to patients. A logical complement to telehealth is "teleconsent." Teleconsent can be defined as using remote, facial integrated identity verification to allow (a) remote guidance of participants through consent documents, and (b) digital signing by all parties, obviating the need for in person signed consent. The ability to review and sign consent documents via telehealth with synchronous viewing is a novel, innovative means by which to overcome the initial significant barrier to recruitment of rural participants into healthcare research. By leveraging the growing capabilities of telehealth, teletailoring studies can improve the efficiency of research recruitment and facilitate the consent process for under-represented populations in research. Strategies for implementation are clearly relevant to increasing the success of clinical trial recruitment.

Provider Advice About Weight Loss in a Primary Care Sample of Obese and Overweight Patients

Objective: Primary care providers play an important role in obesity prevention and reduction by advising patients about weight loss strategies. This study examined receipt of provider advice to lose weight among primary care patients who were overweight and obese. Methods: Observational study conducted among primary care patients (n = 282) who completed a survey that measured receipt of provider advice about weight loss/management, chronic health conditions, perceived weight status, and perceptions about shared decision making about weight loss/management. Results: Fifty-nine percent of participants had been advised by their physician to lose weight. Participants who were obese were more likely than those who were overweight to report provider advice (odds ratio [OR] = 1.31, 95% CI = 1.25-4.34, P = .001). Similarly, participants who believed they were obese/overweight had a greater likelihood of reporting provider advice compared with those who did not believe they were obese/overweight (OR = 1.40, 95% CI = 2.43-6.37, P = .0001). Shared decision making about weight loss/management was associated with an increased likelihood of reporting provider advice (OR = 3.30, 95% CI = 2.62-4.12, P = .0001). Conclusions: Patient beliefs about their weight status and perceptions about shared decision-making are important to receiving provider advice about weight loss/management among primary care patients. Practice Implications: Continued efforts are needed to enhance provider advice about weight loss/management among obese/overweight patients.

A comparative effectiveness education trial for lifestyle health behavior change in African Americans

Obesity and excess weight are significant clinical and public health issues that disproportionately affect African Americans because of physical inactivity and unhealthy eating. We compared the effects of alternate behavioral interventions on obesity-related health behaviors. We conducted a comparative effectiveness education trial in a community-based sample of 530 adult African Americans. Outcomes variables were physical activity (PA) and fruit and vegetable intake. Outcomes were evaluated at baseline and 1-month following interventions about shared risk factors for cancer and cardiovascular disease (CVD) (integrated, INT) or CVD only (disease-specific). Significant increases were found in the proportion of participants who met PA guidelines from baseline (47.4%) to follow-up (52.4%) (P = 0.005). In the stratified analysis that were conducted to examine interaction between education and intervention group assignment, this effect was most apparent among participants who had ≤high school education and were randomized to INT (OR = 2.28, 95% CI = 1.04, 5.00, P = 0.04). Completing the intervention was associated with a 1.78 odds of meeting PA guidelines (95% CI = 1.02, 3.10, P = 0.04). Education about risk factors for chronic disease and evidence-based strategies for health behavior change may be useful for addressing obesity-related behaviors among African Americans.

Discordance in perceived risk and epidemiological outcomes of prostate cancer among African American men

As guidelines for prostate cancer screening have changed from an annual screening recommendation starting at age 50 to discussing the benefits and harms of screening with health care providers, it is necessary to examine other types of factors that are important to prostate cancer screening decisions among African American men. Perceived risk of developing cancer has been shown to predict cancer control behaviors and is lower among African Americans. We characterized perceived risk of developing prostate cancer among African American men from November 2009 to 2011 and evaluated the relationship between prostate cancer risk perceptions and sociodemographic characteristics, health care experiences, and knowledge and exposure to health information about cancer. Chi square tests and logistic regression were employed to determine independent associations. Overall, men did not believe they were at increased risk of developing prostate cancer; they believed their risk was equivalent to or lower than men the same age. Perceived risk of prostate cancer was associated with income (OR = 0.59, 95% CI = 0.26, 1.34, p = 0.03), hypertension (OR = 2.68, 95% CI = 1.17, 6.16, p = 0.02), and beliefs about the association between race and cancer risk (OR = 2.54, 95% CI = 1.24, 5.20, p = 0.01). Clinic and community-based approaches to improve prostate cancer risk comprehension among African American men are needed to reduce the discordance between perceived risk and epidemiological data on prostate cancer risk factors. Risk education interventions that are developed for African American men may need to integrate information about susceptibility for multiple diseases as well as address strategies for risk reduction and prevention, and chronic disease management.

•

Perceived risk was associated with income, hypertension and race and cancer risk.

•

There is discordance in perceived risk for prostate cancer and risk outcomes data.

•

Clinic and community-based approaches are needed to improve risk comprehension.

Collective Efficacy, Physical Activity, and Health Outcomes Among Mothers

Motherhood is associated with low rates of physical activity that increase disease risk. Most theory-based approaches to increasing physical activity focus on personal rather than social factors. The purpose of this study was to examine the associations among perceptions of community collective efficacy and objectively measured physical activity, self-efficacy, social support, and health. Mothers completed questionnaires and wore a pedometer for 7 days. There was a significant, positive association between physical activity and collective efficacy-social cohesion subscale. In the regression analysis, only age and social support were independent predictors of physical activity. Future studies should examine relationships among collective efficacy and social support and physical activity.

Neighborhood Satisfaction and Colorectal Cancer Screening in a Community Sample of African Americans

Social determinants are important to cancer screening among African Americans. To evaluate the association between social determinants (e.g., psychological characteristics, perceived social environment, cultural beliefs such as present temporal orientation) and colorectal cancer (CRC) screening among African Americans. African American adults (n = 262) ages 50-75 completed a telephone interview. Multivariate logistic regression analysis was used to identify factors having significant independent associations with CRC screening. Only 57% of respondents reported having CRC screening. The likelihood of screening increased with greater neighborhood satisfaction (OR = 1.38, 95% CI = 1.01, 1.90, p = 0.04), older age (OR = 1.75, 95% CI = 1.24, 2.48, p = 0.002), greater self-efficacy (OR = 2.73, 95% CI = 1.40, 5.35, p = 0.003), and health care provider communication (OR = 10.78, 95% CI = 4.85, 29.94, p = 0.0001). Community resources are important precursors to CRC screening and outcomes among African Americans. In addition to addressing psychological factors and patient-provider communication, efforts to ensure the availability of quality health care facilities that provide CRC screening in the neighborhoods where African Americans live are needed.

Social Disorder in Adults with Type 2 Diabetes: Building on Race, Place, and Poverty

The recent resurgence of social and civic disquiet in the USA has contributed to increasing recognition that social conditions are meaningfully connected to disease and death. As a "lifestyle disease," control of diabetes requires modifications to daily activities, including healthy dietary practices, regular physical activity, and adherence to treatment regimens. One's ability to develop the healthy practices necessary to prevent or control type 2 diabetes may be influenced by a context of social disorder, the disruptive social and economic conditions that influence daily activity and, consequently, health status. In this paper, we report on our narrative review of the literature that explores the associations between social disorder and diabetes-related health outcomes within vulnerable communities. We also propose a multilevel ecosocial model for conceptualizing social disorder, specifically focusing on its role in racial disparities and its pathways to mediating diabetes outcomes.

Facilitators and barriers to health promotion in African-American adults: a qualitative systematic review protocol

The objective of this review is to identify, appraise and synthesize the best available qualitative evidence on the barriers and facilitators to participation in health-promoting behaviors as experienced by African-American adults. More specifically, this review will systematically examine scientific literature for the purpose of addressing the following questions.

The Relationship Between the Social Environment and Lifestyle-Related Physical Activity in a Low-Income African American Inner-City Southern Neighborhood

The social ecological model was used to examine individual, interpersonal, and neighborhood characteristics related to lifestyle-related physical activity (PA) in a low-income African American (AA) population in New Orleans, Louisiana. Interviewers administered surveys to randomly-sampled household participants from three low-income, AA neighborhoods in New Orleans, Louisiana. Questions included the social and physical environment, physical activity, interpersonal factors, demographics, height and weight. Logistic regression multivariable models were built predicting whether the respondent met PA guidelines, controlling for neighborhood. Females were less as likely to engage in lifestyle-related PA compared to males (OR 0.46, CI 0.30-0.70). Support specific for PA was correlated with engaging in lifestyle-related PA (OR 1.45, CI 1.14-1.83). The individual and social environment should be considered for increasing PA in AA. Interventions targeting the AA population could consider ways of enhancing social support for PA.

Why the Neighborhood Social Environment Is Critical in Obesity Prevention

The continuing obesity epidemic in the USA calls for the examination of antecedents to the well-known risk factors of physical activity and diet. The neighborhood built environment has been extensively studied in relation to obesity noting an increased risk of development and prevalence of obesity in relation to numerous built environment characteristics (lack of green spaces, higher number of fast food restaurants, low walkability indices). The neighborhood social environment, however, has been less extensively studied but is perhaps an equally important component of the neighborhood environment. The neighborhood social environment, particularly constructs of social capital, collective efficacy, and crime, is associated with obesity among both adults and children. Several studies have identified physical activity as a potential pathway of the neighborhood social environment and obesity association. Further work on social networks and norms and residential segregation, as well as the examination of dietary behaviors and mental health as potential mediating pathways, is necessary. Given the existing evidence, intervening on the neighborhood social environment may prove to be an effective target for the prevention on obesity. Intervention studies that promote healthy behaviors and prevent obesity while addressing aspects of the neighborhood social environment are necessary to better identify targets for obesity prevention.

Increasing collective efficacy for physical activity: Design and rationale of Moms UNITE for Health

BACKGROUND

Mothers are a population that engages in low levels of physical activity due to unique barriers to physical activity. As such, there is a need to develop and implement physical activity interventions for mothers that can be delivered in community settings. The objective of this article is to describe the Moms UNITE (Using Networks to Increase Togetherness and Efficacy) for Health walking intervention. This intervention, based on social cognitive theory, is designed to compare a collective efficacy enhanced intervention to a standard intervention for increasing physical activity and secondary outcomes.

METHODS

In this 6-week, randomized controlled trial, mothers will be assigned to either the standard or intervention (collective efficacy) group. Both groups will receive the same walking intervention and an evidence-based health education program. Strategies and messages focusing on building collective efficacy will be used in the intervention group. Data will be collected at baseline, post-intervention, and follow-up (after a 3 month no-intervention period) using a mixed methods approach.

RESULTS

Quantitative data will include anthropometric measurements, objective physical activity, and questionnaires assessing self- and collective-efficacy. Post-intervention focus groups and weekly process evaluation surveys will describe participants' experiences within the program.

CONCLUSIONS

This paper will serve as a theoretical framework for researchers and public health practitioners to develop and implement community-based walking programs for mothers.

Intervention completion rates among African Americans in a randomized effectiveness trial for diet and physical activity changes

BACKGROUND

The intervention completion rate is an important metric in behavioral and intervention research; trials with limited intervention completion rates may have reduced internal validity. We examined intervention completion rates among 530 African Americans who had been randomized to an integrated (INT) or disease-specific (DSE) risk education protocol as part of a comparative effectiveness trial from September 2009 to August 2012.

METHODS

The interventions were developed by an academic-community partnership using community-based participatory research. Intervention completion rates were determined based on attendance at all four intervention sessions. Intervention completers were participants who completed all four sessions and noncompleters were those who did not complete any session or only completed one to three sessions following randomization.

RESULTS

Seventy-three percent of participants were intervention completers and 27% were noncompleters. There were no differences in intervention completion based on randomization to INT (72%) or DSE (75%), sociodemographic factors, or body mass index (BMI) in the total sample. Different factors were associated significantly with intervention completion within study groups. Among participants randomized to INT, the odds of intervention completion were greater with higher levels of intrinsic motivation, less exposure to information about diet and cardiovascular disease, and greater BMI. Among participants randomized to DSE, the odds of completing the intervention were associated significantly with older age and greater dietary self-efficacy.

CONCLUSIONS

Many African Americans are likely to complete risk education interventions.

IMPACT

Psychologic characteristics should be considered when determining intervention completion rates following randomization in behavioral and intervention trials.
