RESUMO

While past studies have provided evidence linking excessive alcohol consumption to increased risk for cardiovascular diseases (CVDs) and colorectal cancer (CRC), existing data on the effects of moderate alcohol use on these conditions have produced mixed results. The purpose of this study was to investigate the effects of moderate alcohol consumption on risk factors associated with the development of CVDs and CRC in adult rats. Twenty-four, 14-month-old, non-deprived male Wistar rats were randomly assigned to either an ethanol group, which consisted of voluntary access to a 20% (v/v) ethanol solution on alternate days, or a water control group (n = 12/group) for 13 weeks. Blood samples were collected to analyze levels of albumin, glucose, adiponectin, lipids, oxidized low-density lipoprotein cholesterol, high-density lipoprotein cholesterol (HDL-C), apolipoprotein A1 (apoA1), C-reactive protein (CRP), high-mobility group box 1 protein (HMGB-1), tumor necrosis factor-alpha (TNF-α), thyroxine, thyroid-stimulating hormone, 8-oxo-2'-deoxyguanosine (8-oxo-dG), liver function enzymes, and antioxidant capacity. Colonic gene expression related to colon carcinogenesis was also assessed. Ethanol-treated rats were found to have significantly higher HDL-C and apoA1 levels compared to controls. Moderate alcohol consumption led to significantly lower CRP levels and a trend for decrease in HMGB-1, TNF-α, and 8-oxo-dG levels. In the ethanol-exposed group, colonic gene expression of superoxide dismutase was upregulated while aldehyde dehydrogenase 2 showed a trend for increase compared to the control group. These results indicate that adopting a moderate approach to alcohol consumption could potentially improve health biomarkers related to CVD and CRC by increasing HDL-C levels and antioxidant activity and reducing DNA damage and inflammatory activity.

RESUMO

BACKGROUND: Capacity-oriented approaches have the potential to reduce food insecurity (FI) and promote nutrition and health equity in low-resource settings. OBJECTIVE: The objective of this study was to identify multilevel capacities in San Diego County, CA that key informants from diverse food- and nutrition-related stakeholder agencies perceived to be helping to address FI. DESIGN: Trained qualitative interviewers conducted face-to-face, semi-structured interviews (30-60 minutes) with key informants. The Socioecological Model and a capacity-oriented approach informed interview guides. PARTICIPANTS/SETTING: Participants were key informants (n = 23) from diverse purposively sampled stakeholder agencies (n = 16) providing food or nutrition services and programs across San Diego County. Interviews were conducted between April 2019 and December 2021. ANALYSES PERFORMED: Interviews were audio-recorded, transcribed verbatim, and checked for accuracy. The research team conducted thematic content analysis to identify themes. RESULTS: Two interrelated themes, within-agency capacities and across-agency partnerships, collectively appeared to influence each individual agency's ability to provide tailored, holistic care to their clients and, thus, expand each agency's reach and impact to address the 4 domains of food security (ie, quantity, quality, psychological, and social). Multilevel (ie, individual, interpersonal, organizational, and macro) within-agency human, social, and cultural capital (eg, volunteers, staff-client relationships, and cultural competency) positively influenced the reach and impact of the individual agencies by enabling them to provide clients with personalized, holistic care. Alongside within-agency capacities, multilevel (ie, interpersonal, organizational, community, and macro levels) across-agency partnerships allowed individual agencies to address FI more effectively and holistically by connecting clients to other services (eg, housing and mental health) related to the circumstances of FI. CONCLUSIONS: In San Diego County, multilevel capacities in the form of within-agency capacities and across-agency partnerships collectively influenced the effectiveness of stakeholder agencies in addressing the 4 domains of FI among at-risk households. Future research should consider how to evaluate the impact of these existing capacities on FI.
