Potential Societal Savings From Reduced Sodium Consumption in the U.S. Adult Population

Kartika Palar; Roland Sturm

Purpose. Policies that address the food environment at the population level may help prevent chronic disease, but their value to society is still uncertain. Dietary sodium is linked to increased prevalence of hypertension, a primary risk factor for cardiovascular and renal diseases. This study calculates the potential societal savings of reducing hypertension and related cardiovascular disease via a reduction in population-level sodium intake. On average, U. S. adults consume almost twice the recommended maximum of dietary sodium, most of it from processed foods. Design. This study modeled sodium-reduction scenarios by using a cross-sectional simulation approach. The model used population-level data on blood pressure, antihypertensive medication use, and sodium intake from the National Health and Nutrition Examination Survey (1999–2004). This data was then combined with parameters from the literature on sodium effects, disease outcomes, costs, and quality of life to yield model outcomes. Measures. This study calculated the following outcome measures: hypertension prevalence, direct health care costs, and quality-adjusted life years for noninstitutionalized U.S. adults. Analysis. The simulation was conducted with STATA 9.2 and Microsoft Excel. Survey weights were used to calculate population averages. Results. Reducing average population sodium intake to 2300 mg per day, the recommended maximum for adults, may reduce cases of hypertension by 11 million, save

32 billion annually. Greater reductions in population sodium consumption bring even greater savings to society. Conclusions. Large benefits to society may result from efforts to lower sodium consumption on a population level by modest amounts over time. Although savings in direct health care costs are likely to be quite high, they could easily be matched or exceeded by the value of quality-of-life improvements.

Introduction:Food insecurity is a potentially important barrier to the success of antiretroviral therapy (ART) programs in resource-limited settings. We undertook a longitudinal study in rural Uganda to estimate the associations between food insecurity and HIV treatment outcomes. Design:Longitudinal cohort study. Methods:Participants were from the Uganda AIDS Rural Treatment Outcomes study and were followed quarterly for blood draws and structured interviews. We measured food insecurity with the validated Household Food Insecurity Access Scale. Our primary outcomes were: ART nonadherence (adherence <90%) measured by visual analog scale; incomplete viral load suppression (>400 copies/ml); and low CD4+ T-cell count (<350 cells/&mgr;l). We used generalized estimating equations to estimate the associations, adjusting for socio-demographic and clinical variables. Results:We followed 438 participants for a median of 33 months; 78.5% were food insecure at baseline. In adjusted analyses, food insecurity was associated with higher odds of ART nonadherence [adjusted odds ratio (AOR) 1.56, 95% confidence interval (CI) 1.10–2.20, P < 0.05], incomplete viral suppression (AOR 1.52, 95% CI 1.18–1.96, P < 0.01), and CD4+ T-cell count less than 350 (AOR 1.47, 95% CI 1.24–1.74, P < 0.01). Adding adherence as a covariate to the latter two models removed the association between food insecurity and viral suppression, but not between food insecurity and CD4+ T-cell count. Conclusions:Food insecurity is longitudinally associated with poor HIV outcomes in rural Uganda. Intervention research is needed to determine the extent to which improved food security is causally related to improved HIV outcomes and to identify the most effective policies and programs to improve food security and health.

Religious organizations may be uniquely positioned to address HIV by offering prevention, treatment, or support services to affected populations, but models of effective congregation-based HIV programs in the literature are scarce. This systematic review distils lessons on successfully implementing congregation HIV efforts. Peer-reviewed articles on congregation-based HIV efforts were reviewed against criteria measuring the extent of collaboration, tailoring to the local context, and use of community-based participatory research (CBPR) methods. The effectiveness of congregations’ efforts and their capacity to overcome barriers to addressing HIV is also assessed. We found that most congregational efforts focused primarily on HIV prevention, were developed in partnerships with outside organizations and tailored to target audiences, and used CBPR methods. A few more comprehensive programs also provided care and support to people with HIV and/or addressed substance use and mental health needs. We also found that congregational barriers such as HIV stigma and lack of understanding HIV’s importance were overcome using various strategies including tailoring programs to be respectful of church doctrine and campaigns to inform clergy and congregations. However, efforts to confront stigma directly were rare, suggesting a need for further research.

Comparative case studies were used to explore religious congregations’ HIV involvement, including types and extent of activities, interaction with external organizations or individuals, and how activities were initiated and have changed over time. The cases included 14 congregations in Los Angeles County representing diverse faith traditions and races-ethnicities. Activities fell into three broad categories: (1) prevention and education; (2) care and support; and (3) awareness and advocacy. Congregations that engaged early in the epidemic focused on care and support while those that became involved later focused on prevention and education. Most congregations interacted with external organizations or individuals to conduct their HIV activities, but promoting abstinence and teaching about condoms were conducted without external involvement. Opportunities exist for congregations to help address a variety of HIV-related needs. However, activities that are mission-congruent, such as providing pastoral care for people with HIV, raising HIV awareness, and promoting HIV testing, appear easier for congregations to undertake than activities aimed at harm reduction.

Food insecurity continues to be a major challenge in the United States, affecting 49 million individuals. Quantitative studies show that food insecurity has serious negative health impacts among individuals suffering from chronic illnesses, including people living with HIV/AIDS (PLHIV). Formulating effective interventions and policies to combat these health effects requires an in-depth understanding of the lived experience and structural drivers of food insecurity. Few studies, however, have elucidated these phenomena among people living with chronic illnesses in resource-rich settings, including in the United States. Here we sought to explore the experiences and structural determinants of food insecurity among a group of low-income PLHIV in the San Francisco Bay Area. Thirty-four semi-structured in-depth interviews were conducted with low-income PLHIV receiving food assistance from a local non-profit in San Francisco and Alameda County, California, between April and June 2014. Interview transcripts were coded and analysed according to content analysis methods following an inductive-deductive approach. The lived experience of food insecurity among participants included periods of insufficient quantity of food and resultant hunger, as well as long-term struggles with quality of food that led to concerns about the poor health effects of a cheap diet. Participants also reported procuring food using personally and socially unacceptable strategies, including long-term dependence on friends, family, and charity; stealing food; exchanging sex for food; and selling controlled substances. Food insecurity often arose from the need to pay high rents exacerbated by gentrification while receiving limited disability income--​a situation resulting in large part from the convergence of long-standing urban policies amenable to gentrification and an outdated disability policy that constrains financial viability. The experiences of food insecurity described by participants in this study can be understood as a form of structural violence, motivating the need for structural interventions at the policy level that extend beyond food-specific solutions.

Forty‐nine million individuals are food insecure in the United States, where food insecurity and HIV/AIDS are prevalent among the urban poor. Food insecurity is associated with risky sexual behaviours among people living with HIV/AIDS (PLHIV). No qualitative studies, however, have investigated the mechanisms underlying this relationship either in a resource‐rich setting or among populations that include men who have sex with men (MSM).

Objective:Although the physical health benefits of HIV antiretroviral therapy (ART) are well documented, the socioeconomic benefits are still being established. Few studies have examined the effects of ART on food insecurity, although studies suggest there may be a benefit via improved health and ability to work. Design:Twelve-month prospective cohort study of 602 treatment-naive patients initiating clinical care in Uganda. Methods:Longitudinal multivariate logistic regression was used to investigate the effect of ART on food insecurity compared to HIV care without ART. A staged regression approach was used to explore pathways through which ART may affect food insecurity. Results:Food insecurity decreased significantly for both the ART and non-ART groups over time, with the ART group experiencing greater reductions by the end of the study. ART remained a significant predictor of reduction in food insecurity over time after controlling for baseline differences in the regression model (odds ratio 0.642; P < 0.01). Improvements in work and mental health status were identified as potential pathways through which ART may improve food security. Conclusion:Taken together with the well known benefits of food security on ART adherence, treatment retention and clinical outcomes in resource-poor settings, our results suggest that a positive feedback loop of improved functioning and productivity could result from the interaction between food security and ART. Policymakers could leverage this positive cycle by strengthening mental health support and promoting sustainable food security interventions as part of HIV treatment programs.

Optimal strategies to improve food security and nutrition for people living with HIV (PLHIV) may differ in settings where overweight and obesity are prevalent and cardiovascular disease risk is a concern. However, no studies among PLHIV have investigated the impact of food support on nutritional outcomes in these settings. We therefore assessed the effect of food support on food insecurity and body weight in a population of PLHIV with high prevalence of overweight and obesity. We implemented a pilot intervention trial in four government-run HIV clinics in Honduras. The trial tested the effect of a monthly household food ration plus nutrition education (n = 203), compared to nutrition education alone (n = 197), over 12 months. Participants were clinic patients receiving antiretroviral therapy (ART). Assessments were obtained at baseline, 6 and 12 months. Primary outcomes for this analysis were food security, using the validated Latin American and Caribbean Food Security Scale and body weight (kg). Thirty-one percent of participants were overweight (22%) or obese (8%) at baseline. At 6 months, the probability of severe food insecurity decreased by 48.3% (p < 0.01) in the food support group, compared to 11.6% in the education-only group (p < 0.01). Among overweight or obese participants, food support led to average weight gain of 1.13 kg (p < 0.01), while nutrition education alone was associated with average weight loss of 0.72 kg (p < 0.10). Nutrition education alone was associated with weight gain among underweight and normal weight participants. Household food support may improve food security but not necessarily nutritional status of ART recipients above and beyond nutrition education. Improving nutritional tailoring of food support and testing the impact of nutrition education should be prioritized for PLHIV in Latin America and similar settings.
