ABSTRACT

Background and Aim: Previously observed associations between interpregnancy interval (IPI) and perinatal outcomes using a between-individual method may be confounded by unmeasured maternal factors. This study aims to examine the association between IPI and adverse perinatal outcomes using within-individual comparative analyses. Methods: We studied 10,647 individuals from the National Institute of Child Health and Human Development Consecutive Pregnancies Study in Utah with ≥3 liveborn singleton pregnancies. We matched two IPIs per individual and used conditional logistic regression to examine the association between IPI and adverse perinatal outcomes, including preterm birth (PTB, <37 weeks' gestation), small-for-gestational-age (SGA, <10th percentile of sex-specific birthweight for gestational age), low birthweight (LBW, <2,500 g), and neonatal intensive care unit (NICU) admission. Point and 95% confidence interval (CI) estimates were adjusted for factors that vary across pregnancies within individuals. Results: CIs did not unequivocally support either an increase or a decrease in the odds of PTB (adjusted odds ratio [aOR]: 1.31, 95% CI: 0.87, 1.96), SGA (aOR: 0.81, 95% CI: 0.51, 1.28), LBW (aOR: 1.59, 95% CI: 0.90, 2.80), or NICU admission (aOR: 0.96, 95% CI: 0.66, 1.40) for an IPI <6 months compared to 18-23-months IPI (reference), and neither did the CIs for the aOR of IPIs of 6-11 and 12-18 months compared to the reference. In contrast, an IPI ≥24 months was associated with increased odds of LBW (aOR: 1.66, 95% CI: 1.03, 2.66 for 24-29 months; aOR: 2.27, 95% CI: 1.21, 4.29 for 30-35 months; and aOR: 2.09, 95% CI: 1.17, 3.72 for ≥36 months). Conclusions: Using a within-individual comparative method, we did not find evidence that a short IPI compared to the recommended IPI of 18-23 months was associated with increased odds of PTB, SGA, LBW, and NICU admission. IPI ≥ 24 months was associated with increased odds of delivering an LBW infant.

ABSTRACT

Inequalities in breastfeeding programmes and practices have slowed global progress in providing the life-saving protection of breastfeeding for millions of infants despite well-known life-long impacts. As breastfeeding interventions are scaled up, inequalities in coverage and breastfeeding practices should be tracked, particularly in disadvantaged groups, who are likely to suffer the most serious health and developmental impacts of poor childhood nutrition. The literature provides evidence of inequalities in breastfeeding practices, but research is limited on socioeconomic disparities in the coverage of breastfeeding interventions. This paper (1) compares inequalities in breastfeeding practices in intervention and nonintervention areas and (2) documents inequalities in programme coverage by type of intervention. We disaggregated endline evaluation surveys in Bangladesh, Burkina Faso and Vietnam, where rigorous evaluations had documented significant overall improvements, and analysed whether inequalities in breastfeeding practices and programme coverage differed by treatment areas. We used Erreygers index to quantify inequalities and found that breastfeeding practices were largely pro-poor; intervention coverage was not consistently pro-poor. While counselling coverage often favoured women from the poorest quintile, public education/media coverage consistently favoured better-off women. Inequalities favoured more educated mothers in the coverage of combined interventions. None of the programmes had explicit equality objectives. The results indicate the need for introducing specific actions to reduce inequalities in breastfeeding policies and programmes. This is a priority unfinished agenda for nutrition programming.

ABSTRACT

The objective of this study was to test whether adding a text message campaign about the importance of eating eggs and other nutrition-related behaviours to an on-going package of large-scale, diverse social and behaviour change interventions would improve four types of nutrition-related knowledge and behaviour outcomes: child diets (egg consumption as the primary outcome), maternal diets, maternal nutrition knowledge, and maternal participation in additional interventions. The cluster-randomized controlled trial involved a repeat cross-sectional design, recruiting families with children 12-23 months of age at baseline and endline in one plains district of Nepal. Throughout the 1000-day period, 51 text messages were sent to each household at specific time points to reinforce ideal diets and other nutrition-related practices and promote engagement with community health workers and other intervention platforms. The primary outcome was egg consumption and dietary diversity among young children. We found no population-level effect. Some evidence supports that for those who received and opened the SMS intervention, it improved child egg consumption (odds ratio [OR]: 1.41, 95% confidence interval [CI]: 1.03-1.93), child minimum dietary diversity (OR: 1.36, 95% CI: 1.07-1.73), child dietary diversity scores (ß: 0.15, 95% CI: 0.01-0.24), as well as maternal IYCF knowledge (ß: 0.21, 95% CI: 0.08-0.35), participation in health mothers' group meetings (OR: 3.03, 95% CI: 1.91-4.84) and Bhanchhin Aama listenership (OR: 1.36, 95% CI: 1.07-1.73). This study highlights the importance of more research to understand the effectiveness of emerging digital interventions for behaviour change among specific populations, to facilitate nuanced targeting to those who can best benefit from these investments.

ABSTRACT

Adherence to a vegan diet may lower risk of cardiovascular disease among African Americans (AAs). Feasibility and sustainability of adopting a vegan diet may be challenging among AAs who live in regions where soul food is a predominant cuisine. Our hypothesis was that AAs randomized to a culturally adapted vegan diet will have greater adherence to their assigned diet compared with those randomized to a culturally adapted omnivorous diet. AAs (N = 113) with overweight/obesity from South Carolina were included. Dietary intake was measured at months 0, 3, 6, and 12 using 24-hour recalls. Adherence was defined based on recommended animal product intake for each group. Differences in nutrient intakes and dietary indices (Alternative Healthy Eating Index 2010 and healthy plant-based diet index) between groups were evaluated using t-tests. At 12 months, adherence was higher to the vegan (51%) versus omnivorous (35%) diet. Participants assigned to the vegan diet had higher intake of carbohydrates (P = .01) and fiber (P < .001), and lower intake of cholesterol P< .001) and protein (P = .001) compared with participants assigned to the omnivorous diet. Participants adherent to the vegan diet had lower cholesterol intake (P < .001) and higher fiber intake (P = .02) compared with those adherent to the omnivorous diet. Compared with those assigned to the omnivorous diet, participants assigned to the vegan diet had higher Alternative Healthy Eating Index 2010 (P = .01) and healthy plant-based diet index (P < .001) scores. AAs with overweight/obesity were more adherent to a culturally adapted vegan diet versus an omnivorous diet after 1 year, and nutrient and food group intake changes were sustained.

ABSTRACT

OBJECTIVES: We sought to understand the influence of recurrent assessments on the behaviour of children and caregivers in a 2-year study of an agricultural livelihood intervention. DESIGN: This study used qualitative exit interviews from caregivers in the control arm of a large, cluster-randomised control trial, Shamba Maisha. SETTING: The study was conducted in Western Kenya and involved 12 health facilities between 2016 and 2019. PARTICIPANTS: Participants were 99 caregivers in the control arm who had a child that was 6-36 months in age at the start of the study. INTERVENTIONS: Intervention participants within Shamba Maisha received an irrigation pump, farming lessons and a microloan. Control participants received no intervention but were offered the intervention after completing the 2-year study. RESULTS: Despite receiving no formal benefits, control caregivers reported improved mental health and enhanced knowledge of their child's health compared with the beginning of the study and reported changes in the child's play and diet that they attributed to participation in study assessments. Caregivers in the control arm attributed their changed behaviour to recurrent questioning, instrumental support, interactions with study staff and increased health knowledge. CONCLUSIONS: Recurrent assessments altered participant behaviour, which may have made inference of the intervention's impact more difficult. In designing future, such studies with intervention and control arms, a trade-off between the gains in statistical power provided by recurrent visits and the avoidance of alterations in participants' behaviour that could affect responses to assessments must be considered when deciding on the number of visits for assessment. TRIAL REGISTRATION NUMBERS: NCT03170986; NCT02815579.

ABSTRACT

PURPOSE OF REVIEW: Because nutrition plays a crucial role in the development of chronic diseases, ensuring nutrition security is important for promoting population health. Nutrition security is defined as having consistent and equitable access to healthy, safe, affordable foods essential to optimal health and well-being. Distinguished from food security, nutrition security consists of two constructs: healthy diets and nutritional status. The study aimed to identify population measures that reflect the important constructs of nutrition security (i.e., healthy diets and nutritional status) to inform U.S. nutrition security assessment and monitoring. RECENT FINDINGS: Through a narrative review conducted across multiple databases, associations between subconstructs of healthy diets and nutritional status were identified. Of the six subconstructs that constitute healthy diets, nutrient adequacy and moderation were most often used to assess and monitor healthfulness of U.S. population diets and were associated with health outcomes. There is little evidence of an association between health outcomes and macronutrient balance or diversity in the U.S. Thirteen instruments were identified as potentially suitable for measuring at least one subconstruct of healthy diet in the population. This review highlights the importance of nutrition security in addressing population health challenges. It emphasizes the potential use of multiple instruments and measures to comprehensively monitor population nutrition security and inform intervention strategies. Identifying feasible and practical measures for assessing and monitoring nutrition security is imperative for advancing population health and mitigating the burden of chronic diseases.

ABSTRACT

Suaahara, an at-scale multisectoral nutrition programme in Nepal, aimed to advance knowledge and skills of frontline health workers to improve the quality of nutrition and health services at health facility and community levels. This study assessed the impact of Suaahara interventions on knowledge and skills of health facility workers and Female Community Health Volunteers (FCHVs). The study used a quasi-experimental design in which four Suaahara intervention districts were compared with pair-matched comparison districts. One health facility worker and three FCHVs from each survey cluster were included. Baseline survey consisted of 93 health facility workers (2015) and 118 FCHVs (2012), and endline survey (2022) consisted of 40 health facility workers and 120 FCHVs. Difference-in-differences regression models employing intent-to-treat analysis, accounting for clustering at the district level, assessed the impact of intervention. The intervention, relative to comparison, had no effect on health facility workers' knowledge. There was a positive effect, however, on FCHVs' knowledge in intervention relative to comparison areas on exclusive breastfeeding, timing of introduction of complementary feeding, sick child feeding and growth monitoring and promotion (GMP) for children under 2 years. Health facility workers and FCHVs in intervention versus comparison districts had higher endline scores for skills related to measuring the weight of children and pregnant women, measuring the height/length of children, conducting GMP for children under 2 years and identifying malnourished children. Suaahara interventions improved the capacity of health workers, particularly nutrition-related knowledge among FCHVs and GMP-related skills of both health facility workers and FCHVs.

ABSTRACT

BACKGROUND: The prevalence of childhood obesity in the U.S. has increased, likely due to decreased physical activity, increased sedentary behaviour and unhealthy diets. Little is known about the relationships between these factors and weight gain in those under the age of three. OBJECTIVES: This study aimed to understand the longitudinal associations of weight gain over 6-month intervals with child and parent characteristics as children develop from 6 to 36 months. METHODS: Mother and infant data were collected at 6-month intervals from 6 to 36 months. Weight (kg) was the primary outcome variable, and potential explanatory variables included child and parent characteristics, physical activity, motor development, diet and sleep. Structural equation modelling was used to assess associations between explanatory variables and 6-month weight gain. RESULTS: Weight increased ~1 kg per 6-month interval (p < 0.001) from 6 to 36 months. Childcare outside of the home at 12 months was associated with 0.272 kg (p = 0.002) greater weight gain at 18 months, while children's physical activity was associated with 0.228 kg (per 2 SD, p = 0.051) less weight gain during the same time period. Mother's TV and screen media use (0.102 kg per hour/day, p = 0.046) and child's intake of high-energy beverages at 18 months (0.387 kg, p = 0.037) were both associated with greater weight gain at 24 months. CONCLUSION: Childcare, physical activity, screen media use and high-energy beverage consumption might affect weight gain at different time points in early childhood. These insights can inform efforts to prevent excessive weight gain and childhood obesity effectively.

ABSTRACT

OBJECTIVE: HIV stigma undermines antiretroviral treatment (ART) adherence and viral suppression. Livelihood interventions may target drivers of negative attitudes towards people with HIV (PWH) by improving their health and strengthening their economic contributions. We examined the effects of a multisectoral agricultural livelihood intervention on HIV stigma among PWH in western Kenya. DESIGN: Sixteen health facilities were randomly allocated (1 : 1) to intervention or control arms in Shamba Maisha , a cluster randomized controlled trial that aimed to improve HIV-related health through behavioral, mental health, and nutritional pathways. METHODS: The intervention included a farming loan and agricultural and financial training. Participants had access to farmland and surface water and were at least 18 years old, on ART for more than 6 months, and moderately-to-severely food insecure. We measured internalized, anticipated, and enacted HIV stigma semiannually over 2 years using validated scales. In blinded intent-to-treat analyses, we compared changes in scores over 24 months by study arm, using longitudinal multilevel difference-in-differences linear regression models that accounted for clustering. RESULTS: Of 720 enrolled participants (354 intervention), 55% were women, and the median age was 40 years [interquartile range 34-47 years]. Two-year retention was 94%. Compared with the control arm, the intervention resulted in significant decreases ( P  < 0.001) of 0.42 points [95% confidence interval (CI) -0.52 to -0.31) in internalized stigma, 0.43 points (95% CI -0.51 to -0.34) in anticipated stigma, and 0.13 points (95% CI -0.16 to -0.09) in enacted stigma over 24 months. CONCLUSION: The agricultural livelihood intervention reduced HIV stigma among PWH. Poverty-reduction approaches may be a novel strategy for reducing HIV stigma.

ABSTRACT

BACKGROUND: Policy support for "Food is Medicine"-medically tailored meals or groceries to improve health-is rapidly growing. No randomized trials have heretofore investigated the benefits of medically tailored food programs for people living with HIV (PLHIV). METHODS: The CHEFS-HIV pragmatic randomized trial included PLHIV who were clients of Project Open Hand (POH), a San Francisco-based nonprofit food organization. The intervention arm (n = 93) received comprehensive medically tailored meals, groceries, and nutritional education. Control participants (n = 98) received less intensive (POH "standard of care") food services. Health, nutrition, and behavioral outcomes were assessed at baseline and 6 months later. Primary outcomes measured were viral non-suppression and health related quality of life. Mixed models estimated treatment effects as differences-in-differences between arms. RESULTS: The intervention arm had lower odds of hospitalization (odds ratio [OR] = 0.11), food insecurity (OR = 0.23), depressive symptoms (OR = 0.32), antiretroviral therapy adherence <90% (OR = 0.18), and unprotected sex (OR = 0.18), and less fatty food consumption (ß= -0.170 servings/day) over 6 months, compared to the control arm. There was no difference between study arms in viral non-suppression and health-related quality of life over 6 months. CONCLUSIONS: A "Food-is-Medicine" intervention reduced hospitalizations and improved mental and physical health among PLHIV, despite no impact on viral suppression.

ABSTRACT

AIMS: To examine, among youth and young adults (YYA) with type 1 diabetes (T1D), the association of household food insecurity (HFI) with: 1) HbA1c and 2) episodes of diabetic ketoacidosis (DKA) and severe hypoglycemia. METHODS: HFI was assessed using the U.S. Household Food Security Survey Module in SEARCH for Diabetes in Youth participants with T1D between 2016 and 2019. Linear and logistic regression models adjusted for age, diabetes duration, sex, race, ethnicity, clinic site, parent/participant education, household income, health insurance, and diabetes technology use. RESULTS: Of 1830 participants (mean age 20.8 ± 5.0 years, 70.0 % non-Hispanic White), HbA1c was collected for 1060 individuals (mean HbA1c 9.2 % ± 2.0 %). The prevalence of HFI was 16.4 %. In the past 12 months, 18.2 % and 9.9 % reported an episode of DKA or severe hypoglycemia, respectively. Compared to participants who were food secure, HFI was associated with a 0.33 % (95 % CI 0.003, 0.657) higher HbA1c level. Those with HFI had 1.58 (95 % CI 1.13, 2.21) times the adjusted odds of an episode of DKA and 1.53 (95 % CI 0.99, 2.37) times the adjusted odds of an episode of severe hypoglycemia as those without HFI. CONCLUSIONS: HFI is associated with higher HbA1c levels and increased odds of DKA in YYA with T1D.

ABSTRACT

Livelihoods have changed dramatically over the past decade in low- and middle-income countries (LMIC). These shifts are happening in tandem with shifts in individual and household food choice behaviors. This scoping review aimed to identify and characterize mechanisms through which livelihood changes could affect food choice behaviors in LMIC, including behaviors relating to food production, acquisition, preparation, distribution, and consumption. A literature search was conducted using 4 databases: PubMed, PsycInfo, AGRICOLA, and Embase. The search was further enhanced by expert solicitations. Studies were included if they measured or focused on a livelihood change, described or assessed a change in ≥1 food choice behavior, and focused on LMIC. Studies were excluded if they focused on migration from LMIC to a high-income country. Of the 433 articles that were identified, 53 met the inclusion criteria. Five mechanisms of how livelihood change can affect food choice were identified: occupation, locality, time, income, and social relations. Changes in occupation altered the balance of the availability and affordability of foods in local food environments compared with individual food production. Changes in location, time use, and income influenced where food was purchased, what types of foods were acquired, and how or where foods were prepared. Additionally, changes in social relationships and norms led to expanded food preferences, particularly among urban populations. Time limitations and higher discretionary income were associated with consumption of ultraprocessed foods. Understanding the relationships between the changes in livelihood occuring in LMIC and food choices of households in these countries can inform the development of policies, programs, and other actions to promote sustainable healthy diets and planetary health.

ABSTRACT

Understanding the drivers of improvements in child undernutrition at only the national level can mask subnational differences. This paper aimed to understand the contributions of factors in the enabling environment to observed differences in stunting reduction between districts in Rwanda. In 2017, we conducted 58 semi-structured interviews with mid-level actors (n = 38) and frontline workers (n = 20) implementing Rwanda's multi-sectoral nutrition policy in five districts in which stunting decreased (reduced districts) and five where it increased or stagnated (non-reduced districts) based on Rwanda's 2010 and 2014/15 Demographic and Health Surveys. Mid-level actors are government officials and service providers at the subnational level who represent the frontline of government policy. Interviews focused on political commitment to and policy coherence in nutrition, and contributors to nutrition changes. Responses were coded to capture themes on the changes and challenges of these topics and compared between reduced and non-reduced districts. Descriptive statistics described district characteristics. Political commitment to nutrition was high in both reduced and non-reduced districts. Respondents from reduced districts were more likely to define commitment to nutrition as an optimal implementation of policy, whereas those from non-reduced districts focused more on financial commitment. Regarding coherence, respondents from reduced compared to non-reduced districts were more likely to report the optimal implementation of multi-sectoral nutrition planning meetings, using data to assess plans and progress in nutrition outcomes and integration of nutrition into the agriculture sector. In contrast, respondents from non-reduced districts more often reported challenges in their relationships with national-level stakeholders and nutrition and/or monitoring and evaluation capacities. Enhancing the integration of nutrition in different sectors and improving mid-level actors' capacity to plan and advocate for nutrition programming may contribute to reductions in stunting.

ABSTRACT

BACKGROUND: The Household Food Security Survey Module (HFSSM) was not tailored to people with chronic diseases or young adults (YAs). OBJECTIVES: We aim to evaluate whether the 18-item HFSSM meets assumptions underlying the scale among YAs with diabetes. METHODS: Data from 1887 YAs with youth-onset type 1 diabetes or type 2 diabetes were used from the SEARCH for Diabetes in Youth Study, 2016-2019, and on 925 who returned for the SEARCH Food Security Cohort Study, 2018-2021, all of whom had completed the HFSSM. Guttman scaling properties (affirmation of preceding less severe items) and Rasch model properties (probability to answer an item based on difficulty level) were assessed. RESULTS: Items 3 (balanced meals) and 6 (eating less than one should) were affirmed more frequently than expected (nonmonotonic response pattern). At 1.2%-3.5%, item nonresponse was rare among type 1 diabetes but higher among type 2 diabetes (range: 3.1%-10.6%). Items 9 (not eating the whole day) and 3 did not meet the Guttman scaling properties. Rasch modeling revealed that item 3 had the smallest difficulty parameter. INFIT indices suggested that some responses to item 3 did not match the pattern in the rest of the sample. Classifying household food insecurity (HFI) based on items 1 and 2 compared with other 2-item combinations, including item 3, revealed a substantial undercount of HFI ranging from 5% to 8% points. CONCLUSIONS: Use of the HFSSM among YAs with diabetes could potentially result in biased HFI reporting and affect estimates of HFI prevalence in this population.

ABSTRACT

BACKGROUND: Social unacceptability of food access is part of the lived experience of food insecurity but is not assessed as part of the United States Household Food Security Survey Module (HFSSM). OBJECTIVES: The objectives were as follows: 1) to determine the psychometric properties of 2 additional items on social unacceptability in relation to the HFSSM items and 2) to test whether these 2 items provided added predictive accuracy to that of the HFSSM items for mental health outcomes. METHODS: Cross-sectional data used were from the Intersection of Material-Need Insecurities and HIV and Cardiovascular Health substudy of the Multicenter AIDS Cohort Study/Women's Interagency HIV Study Combined Cohort Study. Data on the 10-item HFSSM and 2 new items reflecting social unacceptability were collected between Fall 2020 and Fall 2021 from 1342 participants from 10 United States cities. The 2 social unacceptability items were examined psychometrically in relation to the HFSSM-10 items using models from item response theory. Linear and logistic regression was used to examine prediction of mental health measured by the 20-item Center for Epidemiologic Studies Depression scale and the 10-item Perceived Stress Scale. RESULTS: The social unacceptability items were affirmed throughout the range of severity of food insecurity but with increasing frequency at higher severity of food insecurity. From item response theory models, the subconstructs reflected in the HFSSM-10 and the subconstruct of social unacceptability were distinct, not falling into one dimension. Regression models confirmed that social unacceptability was distinct from the subconstructs reflected in the HFSSM-10. The social unacceptability items as a separate scale explained more (∼1%) variation in mental health than when combined with the HFSSM-10 items in a single scale, and the social unacceptability subconstruct explained more (∼1%) variation in mental health not explained by the HFSSM-10. CONCLUSIONS: Two social unacceptability items used as a separate scale along with the HFSSM-10 predicted mental health more accurately than did the HFSSM-10 alone.

ABSTRACT

Suaahara was an innovative, complex, multi-sectoral, large-scale, nutrition programme in Nepal to increase exposure to nutrition-related information and services, improve nutrition-related knowledge and practices among pregnant women and mothers of infants and young children, and improve their nutrition. This study evaluated the effectiveness of Suaahara to improve nutrition and nutrition-related practices by comparing changes over 10 years between intervention and comparison districts. The samples of households at baseline in 2012 and endline in 2022 were 2040 and 2480, respectively, from 120 old wards. The impact was estimated using intent-to-treat regression models in which survey year, arm and their interaction were fixed effects, accounting for district clustering, with the interaction estimating differences between arms in changes over time. The intervention, relative to comparison, reduced maternal underweight by 8.43 percentage points (p < 0.001), consistent with improved maternal and fetal condition that was manifested as the greater length of 0.761 z-scores (p = 0.004) of infants 0-5.9 months. Complementary feeding practices with children between 6 and 23.9 months of age improved more in the intervention than comparison districts: child dietary diversity by 0.294 food groups (p = 0.072) and minimum dietary diversity by 9.51 percentage points (p = 0.028), feeding sick child more (p = 0.002) and administering oral rehydration solution and zinc for diarrhoea (p = 0.057) by about 17 percentage points each, and minimum meal frequency (p = 0.004) and minimum acceptable diet (p = 0.022) by about 15 percentage points each. Substantial impacts were demonstrated despite political restructuring, earthquakes, and other major challenges that Nepal and Suaahara faced and limitations in statistical power because of the reduced number of districts that then could be included in the study.

ABSTRACT

The Nutritious Eating with Soul study was a 24-month, randomized behavioral nutrition intervention among African American adults. This present study, which is a secondary analysis of the NEW Soul study, examined changes in dietary acceptability, restraint, disinhibition, and hunger. Participants (n = 159; 79% female, 74% with ≥ college degree, mean age 48.4 y) were randomized to either a soul food vegan (n = 77) or soul food omnivorous (n = 82) diet and participated in a two-year behavioral nutrition intervention. Questionnaires assessing dietary acceptability (Food Acceptability Questionnaire; FAQ) and dietary restraint, disinhibition, and hunger (Three-Factor Eating Questionnaire; TFEQ) were completed at baseline, 3, 6, 12, and 24 months. Mixed models were specified with main effects (group and time) and interaction effects (group by time) to estimate mean differences in FAQ and TFEQ scores using intent-to-treat analysis. After adjusting for employment, education, food security status, sex, and age, there were no differences in any of the FAQ items, total FAQ score, dietary restraint, disinhibition, and hunger at any timepoint except for one item of the FAQ at 12 months. Participants in the vegan group reported a greater increase in satisfaction after eating a meal than the omnivorous group (mean difference 0.80 ± 0.32, 95% CI 0.18, 1.42; P = 0.01). This is one of the first studies to examine differences in dietary acceptability, hunger, and other eating factors among African American adults randomized to either a vegan or omnivorous soul food diet. The findings highlight that plant-based eating styles are equally acceptable to omnivorous eating patterns and have similar changes in hunger, restraint, and disinhibition. These results suggest that plant-based eating styles can be an acceptable dietary pattern to recommend for cardiovascular disease prevention and may result in greater post-meal satisfaction.
