Longitudinal associations between food insecurity and substance use in a cohort of women with or at risk for HIV in the United States.

ABSTRACT: BACKGROUND AND AIMS:Few longitudinal studies have examined the relationship between food insecurity and substance use. We aimed to investigate this relationship using longitudinal data among women with or at risk for HIV in the United States. DESIGN:Women's Interagency HIV Study (WIHS), a prospective cohort study. SETTING:Nine sites across the United States. PARTICIPANTS:A total of 2553 women with or at risk for HIV. MEASUREMENTS:Semi-annual structured interviews were conducted during April 2013-March 2016. Food security (FS) was the primary predictor, measured using the Household Food Security Survey Module. Outcomes were: any illicit substance use except cannabis; licit or illicit cannabis use; stimulant use (crack, cocaine, or methamphetamine); opioid use (heroin or methadone in a non-prescribed way); and prescription drug misuse (prescription narcotics, amphetamines, or tranquilizers in a non-prescribed way) since the last visit. We used multivariable logistic regression with random effects to examine longitudinal associations of current and previous FS with the outcomes simultaneously, adjusting for socio-demographic factors, HIV serostatus, physical health and health insurance. FINDINGS:Average number of visits was 4.6. At baseline, 71% of participants were HIV-seropositive, 44% reported marginal, low, or very low FS, and 13% were using illicit substances. In adjusted analyses, current low and very low FS were significantly associated with 1.59 [95% confidence interval (CI) = 1.02, 2.46; P = 0.039] and 2.48 (95% CI = 1.52, 4.04; P < 0.001) higher odds of any illicit substance use, compared to high FS, and also with higher odds of cannabis, stimulant and opioid use, exhibiting a consistent dose-response relationship. Marginal, low, and very low FS at the previous visit were associated with 1.66 (95% CI = 1.08, 2.54; P = 0.020), 1.77 (95% CI = 1.14, 2.74; P = 0.011), and 2.28 (95% CI = 1.43, 3.64; P < 0.001) higher odds of current illicit substance use. CONCLUSIONS:Food insecurity appears to be longitudinally associated with substance use among US women with or at risk for HIV.

Project description:BackgroundFood insecurity, lack of consistent access to the food needed for an active, healthy life, harms population health. Although substantial biomedical evidence examines the connections between food insecurity and health, fewer studies examine why food insecurity occurs.MethodsWe propose a conceptual understanding of food insecurity risk based on institutions that distribute income-the factor payment system (income distribution stemming from paid labor and asset ownership), transfers within households, and the government tax-and-transfer system. A key feature of our understanding is 'roles' individuals inhabit in relation to the factor payment system: child, older adult, disabled working-age adult, student, unemployed individual, caregiver, or paid laborer. A second feature is that the roles of others in an individual's household also affect an individual's food insecurity risk. We tested hypotheses implied by this understanding, particularly hypotheses relating to role, household composition, and income support programs, using nationally-representative, longitudinal U.S. Current Population Survey data (2016-2019).ResultsThere were 16,884 participants (year 1 food insecurity prevalence: 10.0%). Inhabiting roles of child (Relative Risk [RR] 1.79, 95% Confidence Interval [95%CI] 1.67 to 1.93), disabled working age-adult (RR 3.74, 95%CI 3.25 to 4.31), or unemployed individual (RR 3.29, 95%CI 2.51 to 4.33) were associated with a greater risk of food insecurity than being a paid laborer. Most food insecure households, 74.8%, had members inhabiting roles of child or disabled working age-adult, and/or contained individuals who experienced job loss. Similar associations held when examining those transitioning from food insecurity to food security in year 2.ConclusionsThe proposed understanding accords with the pattern of food insecurity risk observed in the U.S. An implication is that transfer income programs for individuals inhabiting roles, such as childhood and disability, that limit factor payment system participation may reduce food insecurity risk for both those individuals and those in their household.

Project description:BackgroundNeurocognitive impairment (NCI) persists among women living with HIV. Food insecurity is also common among women and may be an important modifiable contributor of NCI.ObjectiveThe goal of this study was to determine the association of food insecurity with neurocognitive function among women living with or without HIV.MethodsFrom 2013 to 2015, we analyzed data from a cross-sectional sample from the Women's Interagency HIV Study (WIHS). Measures included food insecurity and a comprehensive neuropsychological test battery assessing executive function, processing speed, attention/working memory, learning, memory, fluency, and motor function. We conducted multivariable linear regressions to examine associations between food insecurity and domain-specific neurocognitive performance, adjusting for relevant sociodemographic, behavioral, and clinical factors.ResultsParticipants (n = 1,324) were predominantly HIV seropositive (68%), Black/African-American (68%) or Hispanic (16%), and low income (48% reported <$12,000/y), with a median age of 49.6 y (IQR = 43.1, 55.5). Approximately one-third (36%, n = 479) were food insecure. Food insecurity was associated with poorer executive function (b = -1.45, SE = 0.58, P ≤ 0.01) and processing speed (b = -1.30, SE = 0.59, P ≤ 0.05). HIV serostatus modified the association between food insecurity and learning, memory, and motor function (P values <0.05). Food insecurity was positively associated with learning among women living with HIV (b = 1.58, SE = 0.77, P ≤ 0.05) and negatively associated with motor function among HIV-negative women (b = -3.57, SE = 1.08, P ≤ 0.001).ConclusionsFood insecurity was associated with domain-specific neurocognitive function in women, and HIV serostatus modified associations. Food security may be an important point of intervention for ethnically diverse women with low socioeconomic status. Longitudinal studies are warranted to determine potential pathways by which food insecurity is associated with neurocognitive function among women living with or at risk for HIV.
