RESUMO

BACKGROUND: The British Columbia Farmers' Market Nutrition Coupon Program (BC FMNCP) provides households with low incomes with coupons to purchase healthy foods from farmers' markets. OBJECTIVE: To examine the impact of the BC FMNCP on the short-term household food insecurity, malnutrition risk, mental well-being, sense of community (secondary outcomes), and subjective social status (exploratory outcome) of adults with low incomes post-intervention and 16 weeks post-intervention. DESIGN: Secondary analyses from a pragmatic randomized controlled trial conducted in 2019 that collected data at baseline, post-intervention, and 16 weeks post-intervention. PARTICIPANTS/SETTING: Adults ≥18 years with low incomes were randomized to an FMNCP group (n = 143) or a no-intervention control group (n = 142). INTERVENTION: Participants in the FMNCP group received 16 coupon sheets valued at $21 Canadian dollars (CAD)/sheet over 10 to 15 weeks to purchase healthy foods from farmers' markets and were eligible to participate in nutrition skill-building activities. MAIN OUTCOME MEASURES: Outcomes included short-term household food insecurity (modified version of Health Canada's 18-item Household Food Security Survey Module), malnutrition risk (Malnutrition Universal Screening Tool), mental well-being (Warwick-Edinburgh Mental Well-Being Scale), sense of community (Brief Sense of Community Scale), and subjective social status (MacArthur Scale of Subjective Social Status community scale). STATISTICAL ANALYSIS: Mixed-effects linear regression and multinomial logistic regression examined between-group differences in outcomes post-intervention and 16 weeks post-intervention. RESULTS: The risk of marginal and severe short-term household food insecurity was lower among those in the FMNCP group compared with those in the control group (relative risk ratio [RRR] 0.15, P = 0.01 and RRR 0.16, P = 0.02) post-intervention, with sustained reductions in severe household food insecurity 16 weeks post-intervention (RRR 0.11, P = 0.01). No statistically significant differences were observed in malnutrition risk, mental well-being, sense of community, or subjective social status post-intervention or 16 weeks post-intervention. CONCLUSIONS: The BC FMNCP reduced short-term household food insecurity but was not found to improve malnutrition risk or psychosocial well-being among adults with low incomes compared with a no-intervention control group.

RESUMO

Consideration of the definition of the social determinants of health (SDOHs) requires health care to include work, play, and worship environments because they are important to the health of patients and communities. This article attempts to discuss the issues with limited focus on these areas and the importance of using multidisciplinary health-care teams during primary care visits. The expectation from this information is to advance the ability for primary care providers to support patients and the communities they work in to effect change toward decreasing health disparities and enhancing overall health outcomes.

RESUMO

BACKGROUND: Adults with low incomes have lower diet quality than their higher income counterparts. In Canada, the British Columbia Farmers' Market Nutrition Coupon Program (FMNCP) provides coupons to low-income households to purchase healthy foods in farmers' markets. OBJECTIVE: The objective of this study was to examine the impact of the FMNCP on the diet quality of adults with low incomes. METHOD: In a pragmatic randomized controlled trial conducted in 2019, adults with low incomes (≥18 y) were randomly assigned either to an FMNCP intervention (n = 143) or a no-intervention control group (n = 142). The FMNCP group received 16 coupon sheets valued at $21 per sheet over 10-15 wk to purchase healthy foods from farmers' markets. Participants completed a questionnaire and 2 24-h dietary recalls at baseline (0 wk), immediately post-intervention (10-15 wk), and 16-wk post-intervention (26-31 wk). Diet quality was calculated using the Healthy Eating Index-2015 (HEI-2015). Linear mixed-effects regression assessed differences in HEI-2015 total (primary outcome) and component scores (secondary outcomes) between the FMNCP and control groups at post-intervention and 16-wk post-intervention. Subgroup analyses examined program impacts by sex and age group (18-59 y, ≥60 y). RESULTS: There were no significant differences in HEI-2015 total scores between the FMNCP and control groups at post-intervention (-0.07; 95% CI: -4.07, 3.93) or 16-wk post-intervention (1.22; 95% CI: -3.00, 5.44) overall or between subgroups. There were no significant between-group differences in HEI-2015 component scores at post-intervention, although there were significant differences in component scores for dairy and fatty acids at 16-wk post-intervention. CONCLUSION: The FMNCP did not significantly improve diet quality among adults with low incomes over the study period. Further research is needed to explore whether higher subsidy amounts or a longer intervention period is needed to meaningfully improve diet quality among adults with low incomes. This trial was registered at [clinicaltrials.gov] as [NCT03952338].

RESUMO

BACKGROUND: The British Columbia Farmers' Market Nutrition Coupon Program (FMNCP) is a farmers' market food subsidy program that provides low-income households with coupons valued at $21/wk for 16 weeks to purchase healthy foods at participating BC Association of Farmers' Markets members' markets. OBJECTIVE: This study aimed to explore changes, differences, and similarities in participants' experiences and perceived short-term outcomes during and after participating in the FMNCP. DESIGN: A longitudinal qualitative research approach was used to conduct a recurrent cross-sectional analysis. Data generation and analysis were guided by Freedman et al's theoretical framework of nutritious food access. Data generation occurred during 2019 FMNCP program (time 1) and 4 to 7 weeks after (time 2) the program year ended. Data at each time point were analyzed separately using directed content analysis, followed by a comparative analysis to identify changes, differences, and similarities between time points. PARTICIPANTS: Twenty-eight adult participants were interviewed during the program; 24 were re-interviewed post program. SETTING: Three communities in British Columbia, Canada. RESULTS: Three themes were generated: temporary relief and engagement; lasting experiences and outcomes; enhancing participant experiences and outcomes. The first theme related to how participants' experiences and perceived outcomes, such as increased financial support and improved diet quality and health, were temporary. The second theme reflected positive lasting experiences and outcomes from participating in the FMNCP, including increased food and nutrition knowledge and enhanced social ties. The third theme focused on enhancing participants' program experiences and outcomes, including increasing the duration of food subsidies. CONCLUSION: The FMNCP temporarily enhanced access to nutritious foods and had lasting positive effects on participants' nutrition-related knowledge and social outcomes. Nevertheless, participants struggled to maintain healthy eating practices post program due to financial constraints. Expanding farmers' market subsidy programs may improve access to nutritious foods; maintain positive dietary, social, and health outcomes for participants; and reach more low-income households.

RESUMO

OBJECTIVE: The British Columbia Farmers' Market Nutrition Coupon Program (FMNCP) provides low-income households with coupons valued at $21/week for 16 weeks to purchase healthy foods in farmers' markets. Our objective was to explore FMNCP participants' experiences of accessing nutritious foods, and perceived programme outcomes. DESIGN: The current study used qualitative description methodology. Semi-structured interviews were conducted with FMNCP participants during the 2019 farmers' market season. Directed content analysis was used to analyse the data, whereby the five domains of Freedman et al.'s framework of nutritious food access provided the basis for an initial coding scheme. Data that did not fit within the framework's domains were coded inductively. SETTING: One urban and two rural communities in British Columbia, Canada. PARTICIPANTS: Twenty-eight adults who were participating in the FMNCP. RESULTS: Three themes emerged: autonomy and dignity, social connections and community building, and environmental and programmatic constraints. Firstly, the programme promoted a sense of autonomy and dignity through financial support, increased access to high-quality produce, food-related education and skill development and mitigating stigma and shame. Secondly, shopping in farmers' markets increased social connections and fostered a sense of community. Finally, participants experienced limited food variety in rural farmers' markets, lack of transportation and challenges with redeeming coupons. CONCLUSIONS: Participation in the FMNCP facilitated access to nutritious foods and enhanced participants' diet quality, well-being and health. Strategies such as increasing the amount and duration of subsidies and expanding programmes may help improve participants' experiences and outcomes of farmers' market food subsidy programmes.

RESUMO

INTRODUCTION: Low-income populations have poorer diet quality and lower psychosocial well-being than their higher-income counterparts. These inequities increase the burden of chronic disease in low-income populations. Farmers' market subsidies may improve diet quality and psychosocial well-being among low-income populations. In Canada, the British Columbia (BC) Farmers' Market Nutrition Coupon Programme (FMNCP) aims to improve dietary patterns and health among low-income participants by providing coupons to purchase healthy foods from farmers' markets. This study will assess the impact of the BC FMNCP on the diet quality and psychosocial well-being of low-income adults and explore mechanisms of programme impacts. METHODS AND ANALYSIS: In a parallel group randomised controlled trial, low-income adults will be randomised to an FMNCP intervention (n=132) or a no-intervention control group (n=132). The FMNCP group will receive 16 coupon sheets valued at CAD$21/sheet over 10-15 weeks to purchase fruits, vegetables, dairy, meat/poultry/fish, eggs, nuts and herbs at farmers' markets and will be invited to participate in nutrition skill-building activities. Overall diet quality (primary outcome), diet quality subscores, mental well-being, sense of community, food insecurity and malnutrition risk (secondary outcomes) will be assessed at baseline, immediately post-intervention and 16 weeks post-intervention. Dietary intake will be assessed using the Automated Self-Administered 24-hour Dietary Recall. Diet quality will be calculated using the Healthy Eating Index-2015. Repeated measures mixed-effect regression will assess differences in outcomes between groups from baseline to 16 weeks post-intervention. Furthermore, 25-30 participants will partake in semi-structured interviews during and 5 weeks after programme completion to explore participants' experiences with and perceived outcomes from the programme. ETHICS AND DISSEMINATION: Ethical approval was obtained from the University of Calgary Conjoint Health Research Ethics Board, Rutgers University Ethics and Compliance, and University of Waterloo Office of Research Ethics. Findings will be disseminated through policy briefs, conference presentations and peer-reviewed publications. TRIAL REGISTRATION NUMBER: NCT03952338.

RESUMO

OBJECTIVE: Adherence to combination antiretroviral therapy (ART) among pregnant women is essential to attaining the goal of eliminating mother-to-child HIV transmission. The objective of this study was to determine which factors affect adherence to ART among HIV-positive women enrolled in a large prevention of mother-to-child HIV transmission (PMTCT) trial in rural north-central Nigeria. METHODS: The parent study included 372 HIV-positive pregnant women enrolled in a cluster-randomized control trial conducted at 12 health facilities in Nigeria between 2013 and 2015. This secondary analysis included HIV-positive women (and their infants) from the original trial with documented adherence data (n=210, 56.5%). The primary outcome was maternal adherence to ART, determined by self-report and based on the visual analogue scale (VAS) of a validated medication adherence tool. Participants with a VAS score of ≥ 95% were classified as adherent. We employed multivariate logistic regression to evaluate the predictors of maternal ART adherence in the study sample. RESULTS: Approximately 61.0% of study participants (128/210) were adherent to ART. The majority of adherent participants (62.5%, 80/128) were enrolled in the trial intervention arm. The most common cited response for non-adherence was fear of status disclosure. Adherence to ART was associated with study arm (intervention arm vs. control arm, adjusted Odds Ratio (aOR) [95% CI]: 16.95 [5.30-54.23]), maternal ethnicity (Gwari vs. Other, aOR = 0.13 [0.05-0.38]), and partner HIV status (HIV-positive vs. unknown, aOR = 3.14 [1.22-8.07]). CONCLUSION AND GLOBAL HEALTH IMPLICATIONS: Adherence to ART among a cohort of pregnant women enrolled in a PMTCT trial in rural North-Central Nigeria was associated with trial arm, maternal self-reported ethnicity, and partner's HIV status. Increased understanding of the interplay between these factors will enable the development of more targeted and effective interventions.

RESUMO

Objectives: This analysis documents the use of conventional health-care providers, traditional healers, and complementary therapies by Mexican farmworkers; identifies the purposes and perceived helpfulness of these modalities; and delineates variation in the use of traditional healers and complementary therapies. Methods: Two-hundred Mexican farmworkers in North Carolina completed interviews May-September, 2017. The International Complementary and Alternative Medicine Questionnaire (I-CAM-Q) elicited use of conventional health-care providers, traditional healers, and complementary therapies in the previous 12 months. Results: Most of the farmworkers had been treated by a conventional provider (63.0%). One-in-five had been treated by any traditional healer; 19.5% had been treated by a sobador, 4.5% by a curandero, 2.0% by an herbalist, and 2.0% by a spiritual healer. Conventional providers (69.8%) and sobadores (84.6%) most often treated acute conditions; 62.5% had used an herb, 46.0% a vitamin, 57.0% an over-the-counter medicine, and 13.5% a home remedy. Participants used various self-care practices, including music (36.5%), sleep (18.0%), prayer for health (15.0%), and social media (14.0%). Education was inversely associated with the use of a traditional healer and herbs; treatment by a conventional health-care provider was positively associated with using a traditional healer and vitamins. Conclusions: Mexican farmworkers use conventional health-care providers as well as traditional healers and complementary therapies. Research on how use of complementary therapies and a system of medical pluralism affects farmworker health is needed. Health-care providers need to recognize complementary therapy use and provide patient education about ineffective or harmful therapies.

RESUMO

This qualitative literature review aimed to describe the totality of peer-reviewed scientific evidence from 1990 to 2017 concerning validity of self-reported mammography. This review included articles about mammography containing the words accuracy, validity, specificity, sensitivity, reliability or reproducibility; titles containing self-report, recall or patient reports, and breast or 'mammo'; and references of identified citations focusing on evaluation of 2-year self-reports. Of 45 publications meeting the eligibility criteria, 2 conducted in 1993 and 1995 at health maintenance organisations in Western USA which primarily served highly educated whites provided support for self-reports of mammography over 2 years. Methodological concerns about validity of self-reports included (1) telescoping, (2) biased overestimates particularly among black women, (3) failure to distinguish screening and diagnostic mammography, and (4) failure to address episodic versus consistent mammography use. The current totality of evidence supports the need for research to reconsider the validity of self-reported mammography data as well as the feasibility of alternative surveillance data sources to achieve the goals of the Healthy People Initiative.

RESUMO

OBJECTIVES: Diabetes is a chronic disease prevalent in Hispanic/Latino adults, including migrant farmworkers in the US. Its management requires that individuals follow dietary guidelines, which may be difficult for migrant farmworkers due to work and environmental constraints. This analysis is designed to explore potential barriers to and supports for migrant farmworkers' practice of effective dietary self-management. METHODS: Interviews were conducted with 200 Latino migrant farmworkers in North Carolina, including workers with and without diabetes, recruited at housing sites throughout the 2017 agricultural season. The survey instrument included questions designed to elucidate how workers obtain food, prepare and consume food, and maintain food security. RESULTS: Most purchased food is obtained once per week at large grocery stores, with most farmworkers depending on others for transportation. Less than 1 in 5 supplement with garden produce and food from food pantries, farmers markets, and hunting and fishing. About half of lunches and a quarter of dinners are purchased from vendors or other commercial sources. More than 2 in 5 workers report they have to compromise on or lack control of meal content. About 1 in 5 report issues with food security. CONCLUSIONS: The food-related practices of farmworkers would require change to accommodate effective dietary self-management of diabetes. Greater use of sources of fresh produce and other nutrient-dense foods, coupled with greater control over meal content and cooking techniques would be needed. While some accommodations could be encouraged through education, others would require policy change in housing or access to community resources.

RESUMO

PURPOSE: We conducted a study of women recruited at Meharry Medical College, a historically black medical school, to investigate the relationship between diabetes and mammographic breast density. METHODS: A total of 476 women completed in-person interviews, body measurements, and full-field digital mammograms on a Hologic mammography unit from December 2011 to February 2014. Average percent breast density for the left and right breasts combined was estimated using Quantra, an automated algorithm for volumetric assessment of breast tissue. The prevalence of type 2 diabetes was determined by self-report. RESULTS: After adjustment for confounding variables, the mean percent breast density among premenopausal women with type 2 diabetes [[Formula: see text] 13.8 %, 95 % confidence interval (CI) 11.6-15.9] was nonsignificantly lower than that of women without type 2 diabetes ([Formula: see text] 15.9 %, 95 % CI 15.0-16.8) (p = 0.07); however, there was no association among postmenopausal women. The effect of type 2 diabetes in severely obese women (BMI ≥ 35) appeared to differ by menopausal status with a reduction in mean percent breast density in premenopausal women, but an increase in mean percent breast density in postmenopausal women which could have been due to chance. CONCLUSIONS: Confirmation of our findings in larger studies may assist in clarifying the role of the insulin signaling breast cancer pathway in women with high breast density.

RESUMO

PURPOSE: This study assessed whether perinatal factors were associated with breast cancer among Hispanics, a group with fairly low incidence rates of breast cancer. METHODS: Data were used from a case-control study of breast cancer among Hispanics aged 30-79 conducted between 2003 and 2008 on the Texas-Mexico border. In-person interviews were completed with 188 incident breast cancer cases ascertained through surgeons and oncologists, and 974 controls (with respective response rates of 97% and 78%). RESULTS: Relative to birth weight 2500-3999g, there was no elevation in breast cancer risk for birth weight of ≥ 4000g (odds ratio [OR] 0.76, 95% confidence interval [CI] 0.47-1.21). CONCLUSIONS: The results tended to differ slightly from previous studies of this topic perhaps owing to the different hormonal milieu among Hispanics relative to Caucasians, African Americans and Asians in whom all previous studies of this topic have been conducted. Confirmation of these findings in larger studies may assist in determining how hormonal mechanisms responsible for breast cancer differ by ethnicity.

RESUMO

OBJECTIVES: This analysis described Latino migrant farmworkers' work safety climate and its association with musculoskeletal discomfort, working while injured or ill, and depressive symptoms. METHODS: Data were from a cross-sectional survey of 300 farmworkers conducted in North Carolina in 2009. Generalized estimating equations models were used to investigate the association of work safety climate with health and safety outcomes. RESULTS: Farmworkers perceived their work safety climate to be poor. About 40% had elevated musculoskeletal discomfort, 5.0% had worked at least 1 day while injured or ill, and 27.9% had elevated depressive symptoms. The odds of elevated musculoskeletal discomfort were 12% lower and the odds of working while injured or ill were 15% lower with each 1-unit increase in the work safety climate. Work safety climate was not associated with depressive symptoms. CONCLUSIONS: Work safety climate was important for agricultural workers. Poor work safety climate was associated with health outcomes (musculoskeletal discomfort) and safety (working while injured or ill). Interventions to improve work safety climate in agriculture are needed, with these interventions being directed to employers and workers.
