Alcohol Consumption and Illicit Drug Use: Associations With Fall, Fracture, and Acute Health Care Utilization Among People With HIV Infection

BACKGROUND

Given alcohol and/or other drug (AOD) use occurs among people with HIV (PWH), we examined its association with falls and fall-related outcomes and whether frailty moderates the association.

SETTING

Northeastern US city.

METHODS

We analyzed an observational cohort of PWH with current or past AOD use. Alcohol measures were any past 14-day heavy use, average alcohol/day, and days with heavy use. Drug use measures were past 30-day illicit use of cocaine, opioids, and sedatives. Repeated cross-sectional associations were estimated with separate multivariable generalized estimating equation regression models for each fall-related outcome.

RESULTS

Among PWH (n = 251; mean age 52 [SD = 10]), 35% reported heavy alcohol use, 24% cocaine, 16% illicit opioids, 13% illicit sedatives, and 35% any fall; 27% were frail. Heavy alcohol use was associated with a fall (AOR = 1.49, 95% CI: 1.08 to 2.07), multiple falls (AOR = 1.55 95% CI: 1.10 to 2.19), and fall/fracture-related emergency department visit or hospitalization (AOR = 1.81, 95% CI: 1.10 to 2.97). Higher average alcohol/day and more heavy drinking days were associated with multiple falls. Illicit sedative use was associated with a fall, multiple falls, and emergency department visit/hospitalization and opioid use with fracture. Frailty moderated the association of heavy alcohol use and a fall (AOR = 2.26, 95% CI: 1.28 to 4.01 in those frail) but not in those not frail.

CONCLUSION

The effect of AOD use on falls and fall-related outcomes was most pronounced with alcohol, particularly among frail PWH. Heavy alcohol, illicit sedative, and illicit opioid use are high-priority targets for preventing falls and fall-related consequences for PWH.

Self-medication of pain and discomfort with alcohol and other substances by people with HIV infection and substance use disorder: preliminary findings from a secondary analysis

There is a limited literature regarding factors associated with self-medication of pain and discomfort using alcohol, non-prescription substances or overuse of prescription medications among people living with Human Immunodeficiency Virus (HIV). This cross-sectional analysis used data from the Boston ARCH Cohort among participants with HIV infection and a history of alcohol or other substance use. Among 248 participants, 37% were female, 50% Black, 25% Latinx; 36% reported fair to poor health and 89% had CD4 cell counts >200/mm3. Half reported self-medication and of those, 8.8% reported doing so only with alcohol, 48.8% only with other substances and 42.4% with both alcohol and other substances. Those reporting self-medication were significantly (p < .05) younger (mean 47 vs 50 years), less employed (11% vs 21%), and less likely to have HIV viral suppression (60% vs. 80%). Depression, anxiety, and HIV symptoms were associated with significantly greater odds of self-medicating, as were substance dependence, recent injection substance use, heavy alcohol use, cocaine use, opioid use, sedative use, and cannabis use. Self-medication, highly prevalent and associated with worse mental health symptoms, greater substance use, and lesser HIV disease control, should be explored by HIV clinicians caring for people who use substances.

Heavy Alcohol Use and HIV Outcomes: The Moderating Role of Pain

Pain and heavy alcohol consumption are prevalent among people living with HIV/AIDS (PLWH), each contributing to impaired functioning and diminished quality of life. Each of these conditions may have negative effects on the HIV care continuum, but less is known about their combined influences. The current study examined how heavy drinking and pain were associated with HIV viral suppression and CD4 cell count among participants receiving antiretroviral therapy (ART). The study sample consisted of 220 PLWH with past 12-month substance dependence or ever injection drug use enrolled in a large HIV cohort study. Logistic regression analyses showed an interaction between pain level (no/mild pain vs moderate/severe) and heavy drinking on viral suppression such that heavy drinking was a significant predictor of poorer viral suppression only for those who experienced moderate/severe pain. We also examined whether ART adherence differentially mediated the association between heavy drinking and HIV viral suppression by level of pain. Although there was a significant indirect effect of heavy drinking on viral suppression among those with moderate/severe pain, moderated mediational analyses did not indicate that the indirect effect of heavy drinking on viral suppression through ART adherence differed significantly by level of pain. Pain level did not significantly moderate the association between heavy drinking and CD4 cell count. We conclude that heavy drinking may be particularly likely to be associated with poorer HIV viral suppression among PLWH with moderate or severe pain. Providers should routinely address comorbid heavy drinking and pain to improve HIV outcomes.

Development and Validation of an Abbreviated Child and Adult Food Security Scale for Use in Clinical and Research Settings in the United States

BACKGROUND

Food insecurity (FI) prevalence was consistently >10% over the past 20 years, indicating chronic economic hardship. Recession periods exacerbate already high prevalence of FI, reflecting acute economic hardship. To monitor FI and respond quickly to changes in prevalence, an abbreviated food security scale measuring presence and severity of household FI in adults and children is needed.

OBJECTIVE

Our aim was to develop an abbreviated, sensitive, specific, and valid food security scale to identify severity levels of FI in households with children.

DESIGN

Cross-sectional and longitudinal survey data were analyzed for years 1998 to 2022.

PARTICIPANTS/SETTING

Participants were racially diverse primary caregivers of 69,040 index children younger than 4 years accessing health care in 5 US cities.

STATISTICAL ANALYSES PERFORMED

Sensitivity, specificity, positive and negative predictive values, accuracy, and area under the receiver operator curve were used to test combinations of questions for the most effective abbreviated scale to assess levels of severity of adult and child FI compared with the Household Food Security Survey Module. Adjusted logistic regression models assessed convergent validity between the Abbreviated Child and Adult Food Security Scale (ACAFSS) and health measures. McNemar tests examined the ACAFSS performance in times of acute economic hardship.

RESULTS

The ACAFSS exhibited 91.2% sensitivity; 99.6% specificity; 98.3% and 97.6% positive and negative predictive values, respectively; 97.7% accuracy; and a 99.6% area under the receiver operator curve, while showing high convergent validity.

CONCLUSIONS

The ACAFSS is highly sensitive, specific, and valid for detecting severity levels of FI among racially diverse households with children. The ACAFSS is recommended as a stand-alone scale or a follow-up scale after households with children screen positive for FI risk. The ACAFSS is also recommended for planning interventions and evaluating their effects not only on the binary categories of food security and FI, but also on changes in levels of severity, especially when rapid decision making is crucial.

Cannabis use frequency and pain interference among people with HIV

Cannabis is often used by people with HIV (PWH) for pain, yet study results are inconsistent regarding whether and how it affects pain. This study examines whether greater cannabis use frequency is associated with lower pain interference and whether cannabis use modifies the association of pain severity and pain interference among 134 PWH with substance dependence or a lifetime history of injection drug use. Multi-variable linear regression models examined the association between past 30-day cannabis use frequency and pain interference. Additional models evaluated whether cannabis use modified the association between pain severity and pain interference. Cannabis use frequency was not significantly associated with pain interference. However, in a model with interaction between cannabis use frequency and pain severity, greater cannabis use frequency attenuated the strength of the association between pain severity and pain interference (p = 0.049). The adjusted mean difference (AMD) in pain interference was +1.13, + 0.81, and +0.05 points for each 1-point increase in pain severity for those with no cannabis use, 15 days of use, and daily use, respectively. These findings suggest that attenuating the impact of pain severity on pain-related functional impairment is a potential mechanism for a beneficial role of cannabis for PWH.

Burden of Chronic Obstructive Pulmonary Disease Attributable to Tuberculosis: A Microsimulation Study

Tuberculosis (TB) is a risk factor for chronic obstructive pulmonary disease (COPD), but COPD is also a predictor of TB. The excess life-years lost to COPD caused by TB can potentially be saved by screening for and treating TB infection. We examined the number of life-years that could be saved by preventing TB and TB-attributable COPD. We compared the observed (no intervention) and counterfactual microsimulation models constructed from observed rates in the Danish National Patient Registry (covering all Danish hospitals between 1995 and 2014). In the Danish population of TB and COPD-naive individuals (n = 5,206,922), 27,783 persons (0.5%) developed TB. Among those who developed TB, 14,438 (52.0%) developed TB with COPD. Preventing TB saved 186,469 life-years overall. The excess number of life-years lost to TB alone was 7.07 years per person, and the additional number of life-years lost among persons who developed COPD after TB was 4.86 years per person. The life-years lost to TB-associated COPD are substantial, even in regions where TB can be expected to be identified and treated promptly. Prevention of TB could prevent a substantial amount of COPD-related morbidity; the benefit of screening and treatment for TB infection is underestimated by considering morbidity from TB alone.

Impact of alcohol use disorder severity on human immunodeficiency virus (HIV) viral suppression and CD4 count in three international cohorts of people with HIV

BACKGROUND

Alcohol use has been linked to worse human immunodeficiency virus (HIV) immunologic/virologic outcomes, yet few studies have explored the effects of alcohol use disorder (AUD). This study assessed whether AUD severity is associated with HIV viral suppression and CD4 count in the three cohorts of the Uganda Russia Boston Alcohol Network for Alcohol Research Collaboration on HIV/AIDS (URBAN ARCH) Consortium.

METHODS

People with HIV (PWH) in Uganda (n = 301), Russia (n = 400), and Boston (n = 251), selected in-part based on their alcohol use, were included in analyses. Logistic and linear regressions were used to assess the cross-sectional associations between AUD severity (number of DSM-5 diagnostic criteria) and (1) HIV viral suppression, and (2) CD4 count (cells/mm3 ) adjusting for covariates. Analyses were conducted separately by site.

RESULTS

The proportion of females was 51% (Uganda), 34% (Russia), and 33% (Boston); mean age (SD) was 40.7 (9.6), 38.6 (6.3), and 52.1 (10.5), respectively. All participants in Uganda and all but 27% in Russia and 5% in Boston were on antiretroviral therapy. In Uganda, 32% met criteria for AUD, 92% in Russia, and 43% in Boston. The mean (SD) number of AUD criteria was 1.6 (2.4) in Uganda, 5.6 (3.3) in Russia, and 2.4 (3.1) in Boston. Most participants had HIV viral suppression (Uganda 92%, Russia 57%, Boston 87%); median (IQR) CD4 count was 673 (506, 866), 351 (201, 542), and 591 (387, 881), respectively. In adjusted models, there were no associations between AUD severity and HIV viral suppression: adjusted odds ratios (AOR) (95%CI) per 1 additional AUD criterion in Uganda was 1.08 (0.87, 1.33); Russia 0.98 (0.92, 1.04); and Boston 0.95 (0.84, 1.08) or CD4 count: mean difference (95%CI) per 1 additional criterion: 5.78 (-7.47, 19.03), -3.23 (-10.91, 4.44), and -8.18 (-24.72, 8.35), respectively.

CONCLUSIONS

In three cohorts of PWH, AUD severity was not associated with HIV viral suppression or CD4 count. PWH with AUD in the current era of antiretroviral therapy can achieve virologic control.

Alcohol and falls among people with HIV infection: A view from Russia and the United States

BACKGROUND

Both human immunodeficiency virus (HIV) infection and alcohol use predispose to autonomic/sensory neuropathy, imbalance symptoms, and cognitive impairment-conditions associated with a greater risk of falls-yet it is unclear how to identify people with HIV (PWH) whose drinking is associated with falls. Research on alcohol and falls using the same instruments in different countries could help to specify the level of alcohol use associated with fall risk. We examined whether a consumption-based measure (the Alcohol Use Disorders Identification Test-Consumption [AUDIT-C]) and/or a symptom-based measure (DSM-5 criteria for alcohol use disorder [AUD]) are associated with sustaining a fall among PWH in St Petersburg, Russia and Boston, Massachusetts in the United States.

METHODS

Separate multivariate logistic regressions were used for each cohort to examine cross-sectional associations for each alcohol measure predicting fall. Potential confounders included physical functioning, depressive symptoms, and other substance use (measured with the Addiction Severity Index).

RESULTS

A fall was reported by 35% (87/251) of the sample in Boston and 12% (46/400) in St Petersburg. Each additional AUD criterion-but not higher AUDIT-C score-was significantly associated with a fall in both Boston (odds ratio [OR] = 1.10; 95% confidence interval [CI] 1.02, 1.18) and St Petersburg (adjusted OR AOR = 1.10; 95% CI 1.02, 1.18). Heavy alcohol use (>6 drinks/occasion, any vs. none) was associated with more than twice the odds of a fall (AOR = 2.24; 95% CI 1.21, 4.13) in Boston.

CONCLUSIONS

These findings suggest that while fall risk may vary by setting and population, heavy alcohol use and AUD symptom severity are potential targets for interventions to prevent falls. Studies in diverse global settings advance our understanding of the relationship between alcohol and falls in PWH.

Associations of spousal and non-spousal caregiving with six-year trajectories of depressive symptoms among older women in the Caregiver-Study of Osteoporotic Fractures study

Objectives:Caregiving and becoming widowed are risk factors for depression in older adults, but few studies have examined their combined effect on depressive symptom trajectories. In a cohort of older women (mean age = 80.7 years) from the Caregiver-Study of Osteoporotic Fractures, we used latent class growth curve modeling to identify trajectories of depressive symptoms over approximately six years.Method:We used multinomial logistic regression to assess the relative odds of four depressive symptom trajectories (consistently low, consistently moderate, moderate/increasing, and consistently high), among three groups: spousal caregivers (n = 149), non-spousal caregivers (n = 157), and non-caregivers (n = 422). We also repeated this analysis with combined caregiving status and widowhood as the exposure.Results:Compared to non-caregivers, spousal caregivers had greater relative odds of consistently high versus consistently low depressive symptoms (adjusted odds ratio [aOR] = 3.6, 95% confidence interval [CI]: 1.9, 6.5). Non-spousal caregivers did not differ from non-caregivers in depressive trajectories. Compared to non-caregivers who did not become widowed, both widowed and non-widowed spousal caregivers had greater relative odds of consistently high versus consistently low depressive symptoms (aOR = 4.9, 95% CI: 1.9, 12.7 and aOR = 3.0, 95% CI: 1.5, 6.0, respectively). Non-widowed spousal caregivers, but not widowed spousal caregivers, had a non-statistically-significant trend toward increased relative odds of moderate/increasing depressive symptoms (aOR = 1.5, 95% CI: 0.7, 3.4).Conclusion:Spousal caregiving and widowhood, but not non-spousal caregiving, are associated with trajectories reflecting greater depressive symptoms over time. Informal caregiving is common among older women, and women caring for spouses should be monitored for depression, both during caregiving and after spousal loss.Supplemental data for this article can be accessed online at https://doi.org/10.1080/13607863.2021.1950611.

Effect of Culturally Tailored, Internet-Delivered Cognitive Behavioral Therapy for Insomnia in Black Women: A Randomized Clinical Trial

IMPORTANCE

Black women are at risk for insomnia disorder. Despite interest in addressing sleep health disparities, there is limited research investigating the efficacy of criterion-standard treatment (cognitive behavioral therapy for insomnia [CBT-I]) among this racial minority population.

OBJECTIVE

To compare the efficacy of a standard version of an internet-delivered CBT-I program, a culturally tailored version, and a sleep education control at improving insomnia symptoms.

DESIGN, SETTING, AND PARTICIPANTS

In this single-blind, 3-arm randomized clinical trial, participants in a national, longitudinal cohort (Black Women's Health Study [BWHS]) were recruited between October 2019 and June 2020. BWHS participants with elevated insomnia symptoms were enrolled and randomized in the current study.

INTERVENTIONS

Participants were randomized to receive (1) an automated internet-delivered treatment called Sleep Healthy Using the Internet (SHUTi); (2) a stakeholder-informed, tailored version of SHUTi for Black women (SHUTi-BWHS); or (3) patient education (PE) about sleep.

MAIN OUTCOMES AND MEASURES

The primary outcome was insomnia severity (Insomnia Severity Index [ISI]). Index score ranged from 0 to 28 points, with those scoring less than 8 points considered to not have clinically significant insomnia symptoms and a score of 15 points or higher suggesting insomnia disorder. An ISI score reduction of more than 7 points was considered a clinically significant improvement in insomnia symptoms. The SHUTi-BWHS program was hypothesized to be more effective at significantly decreasing insomnia severity compared with the SHUTi program and PE.

RESULTS

A total of 333 Black women were included in this trial, and their mean (SD) age was 59.5 (8.0) years. Those randomized to receive either SHUTi or SHUTi-BWHS reported significantly greater reductions in ISI score at 6-month follow-up (SHUTi: -10.0 points; 95% CI, -11.2 to -8.7; SHUTi-BWHS: -9.3 points; 95% CI, -10.4 to -8.2) than those randomized to receive PE (-3.6 points; 95% CI, -4.5 to -2.1) (P < .001). Significantly more participants randomized to SHUTi-BWHS completed the intervention compared with those randomized to SHUTi (86 of 110 [78.2%] vs 70 of 108 [64.8%]; P = .008). Participants who completed either intervention showed greater reductions in insomnia severity compared with noncompleters (-10.4 points [95% CI, -11.4 to -9.4] vs -6.2 points [95% CI, -8.6 to -3.7]).

CONCLUSIONS AND RELEVANCE

In this randomized clinical trial, both the SHUTi and SHUTi-BWHS programs decreased insomnia severity and improved sleep outcomes more than PE. The culturally tailored SHUTi-BWHS program was more effective at engaging participants with the program, as a greater proportion completed the full intervention. Program completion was associated with greater improvements in sleep.

Household unmet basic needs in the first 1000 days and preterm birth status

OBJECTIVE

To examine the relationship of individual and composite number of unmet basic needs (housing, energy, food, and healthcare hardships) in the past year with preterm birth status among children aged 0-24 months.

STUDY DESIGN

We examined cross-sectional 2011-18 data of 17,926 families with children aged 0-24 months. We examined children born <31 weeks', 31-33 weeks', and 34-36 weeks' gestation versus term (≥37 weeks) using multivariable multinomial logistic regression.

RESULTS

At least 1 unmet basic need occurred among ≥60% of families with preterm children, compared to 56% of families with term children (p = 0.007). Compared to term, children born ≤30 weeks' had increased odds of healthcare hardships (aOR 1.28 [1.04, 1.56]) and children born 34-36 weeks' had increased odds of 1 (aOR 1.19 [1.05, 1.35]) and ≥2 unmet needs (aOR 1.15 [1.01, 1.31]).

CONCLUSION

Unmet basic needs were more common among families with preterm, compared to term children.

Variation in United States COVID-19 newborn care practices: results of an online physician survey

Background

Newborn care practices that best promote the health and well-being of mother-infant dyads after birth while minimizing transmission of COVID-19 were uncertain at the onset of the COVID-19 pandemic.

Objective

Examine variation in COVID-19 newborn care practices among U.S. birth hospitals and by hospital characteristics (U.S. census region, highest level of neonatal level of care, and Baby-Friendly hospital status).

Study Design

We surveyed physicians via American Academy of Pediatrics email listservs and social media between 5/26/2020-6/8/2020. Physicians identified the birth hospital in which they provided newborn care and their hospital’s approach to obstetrical and newborn care related to COVID-19. Chi-square tests were used to examine variation in hospital practices by U.S. census region, highest level of neonatal care, and Baby-Friendly hospital status.

Results

Four hundred thirty three physicians responded from 318 hospitals across 46 states. Variation in care of SARS-CoV-2 positive mother-infant dyads was greatest for approaches to location of newborn care (31% separation, 17% rooming-in, and 51% based on shared-decision making), early skin-to-skin care (48% prohibited/discouraged, 11% encouraged, and 40% based on shared-decision making) and direct breastfeeding (37% prohibited/discouraged, 15% encouraged, and 48% based on shared-decision making). Among presumed uninfected dyads, 59% of hospitals discharged at least some mother-infant dyads early. We found variation in practices by U.S. census region.

Conclusion

Approaches to newborn care and breastfeeding support for mother-infant dyads with positive SARS-CoV-2 testing differed across U.S. birth hospitals during the COVID-19 pandemic. Early discharge of presumed uninfected mother-infant dyads was common.

Trends in Cannabis Involvement and Risk of Alcohol Involvement in Motor Vehicle Crash Fatalities in the United States, 2000‒2018

Objectives. To assess cannabis and alcohol involvement among motor vehicle crash (MVC) fatalities in the United States. Methods. In this repeated cross-sectional analysis, we used data from the Fatality Analysis Reporting System from 2000 to 2018. Fatalities were cannabis-involved if an involved driver tested positive for a cannabinoid and alcohol-involved based on the highest blood alcohol concentration (BAC) of an involved driver. Multinomial mixed-effects logistic regression models assessed cannabis as a risk factor for alcohol by BAC level. Results. While trends in fatalities involving alcohol have remained stable, the percentage of fatalities involving cannabis and cannabis and alcohol increased from 9.0% in 2000 to 21.5% in 2018, and 4.8% in 2000 to 10.3% in 2018, respectively. In adjusted analyses, fatalities involving cannabis had 1.56 (95% confidence interval [CI] = 1.48, 1.65), 1.62 (95% CI = 1.52, 1.72), and 1.46 (95% CI = 1.42, 1.50) times the odds of involving BACs of 0.01% to 0.049%, 0.05% to 0.079%, and 0.08% or higher, respectively. Conclusions. The percentage of fatalities involving cannabis and coinvolving cannabis and alcohol doubled from 2000 to 2018, and cannabis was associated with alcohol coinvolvement. Further research is warranted to understand cannabis- and alcohol-involved MVC fatalities. (Am J Public Health. 2021;111(11):1976-1985. https://doi.org/10.2105/AJPH.2021.306466).

Community health worker-delivered weight management intervention among public housing residents: A feasibility study

Community health worker-led interventions may be an optimal approach to promote behavior change among populations with low incomes due to the community health workers’ unique insights into participants’ social and environmental contexts and potential ability to deliver interventions widely. The objective was to determine the feasibility (implementation, acceptability, preliminary efficacy) of a weight management intervention for adults living in public housing developments. In 2016–2018, in Boston Massachusetts, we conducted a 3-month, two-group randomized trial comparing participants who received a tailored feedback report (control group) to participants who received the same report plus behavioral counseling. Community health workers provided up to 12 motivational interviewing-based counseling sessions in English or Spanish for diet and physical activity behaviors using a website designed to guide standardized content delivery. 102 participants enrolled; 8 (7.8%) were lost at 3-month follow up. Mean age was 46.5 (SD = 11.9) years; the majority were women (88%), Hispanic (67%), with ≤ high school degree (62%). For implementation, among intervention group participants (n = 50), 5 completed 0 sessions and 45 completed a mean of 4.6 (SD = 3.1) sessions. For acceptability, most indicated they would be very likely (79%) to participate again. For preliminary efficacy, adjusted linear regression models showed mean changes in weight (-0.94 kg, p = 0.31), moderate-to-vigorous physical activity (+11.7 min/day, p = 0.14), and fruit/vegetable intake (+2.30 servings/day, p < 0.0001) in the intervention vs. control group. Findings indicate a low-income public housing population was reached through a community health worker-led intervention with sufficient implementation and acceptability and promising beneficial changes in weight, nutrition, and physical activity outcomes.

Disparities in Breastfeeding Among U.S. Black Mothers: Identification of Mechanisms

Objective: Disparities in U.S. breastfeeding rates persist among Black mothers according to birth country and between Black and White mothers, necessitating further investigation of modifiable mediating factors to inform interventions. This study seeks to examine the extent that social, maternal, infant factors and Theory of Planned Behavior (TPB) domains (attitudes, perceived control, and subjective norms) mediate the association of maternal race/birth country and breastfeeding continuation. Methods: A national cohort of 2,050 mothers self-identifying as U.S.-born non-Hispanic Black (n = 689), foreign-born non-Hispanic Black (n = 139), and U.S.-born non-Hispanic White (n = 1,222) was analyzed. Using logistic regression, associations of race/birth country and any/exclusive breastfeeding at 2-6 months were examined. Structural equation modeling was used to determine whether social, maternal, and infant factors and TPB domains mediate these relationships. Results: 40.0% of U.S.-born Black, 82.2% of foreign-born Black, and 57.3% of U.S.-born White mothers reported any breastfeeding at 2-6 months. Compared with U.S.-born Black mothers, odds of any breastfeeding were sevenfold higher among foreign-born Black mothers (odds ratio [OR] = 7.04 95% confidence interval [CI] = 4.80-10.31), which was explained partly by social/maternal/infant factors and TPB domains. Compared with U.S.-born White mothers, any breastfeeding was lower (OR = 0.54, 95% CI = 0.40-0.73) among U.S.-born Black mothers and higher (OR = 3.81, 95% CI = 2.48-5.87) among foreign-born Black mothers; these differences were also mediated by the aforementioned factors. Conclusions: Among Black mothers in the United States, breastfeeding continuation varied substantially by birth country. Promotion of interventions targeting positive attitudes, perceived control, and subjective norms may reduce disparities among Black and between Black and White mothers.

National Prevalence of Donor Milk Use Among Level 1 Nurseries

BACKGROUND AND OBJECTIVES

Donor milk use has increased among very preterm infants because of mounting evidence of health benefits; however, the extent that donor milk is used among healthy term infants in level 1 nurseries is unclear. We aimed to determine (1) national prevalence of and (2) hospital factors associated with donor milk use in level 1 nurseries.

METHODS

Among 3040 US birthing hospitals, we randomly selected hospitals from each of 4 US regions (119 in northeast, 120 in Midwest, 116 in west, and 103 in south) for a total of 458 hospitals. We surveyed the nursing leaders of these hospitals from October to December 2017 regarding routine use of donor milk in the level 1 nursery (yes or no). To estimate national prevalence, we weighted responses according to the number of birthing hospitals within each region. We examined relationships between routine donor milk use in the level 1 nursery and hospital characteristics using multivariable logistic regression.

RESULTS

In total, 214 of 458 (47%) nursing leaders responded. The national prevalence of routine donor milk use in level 1 nurseries was 17.6%. Eighty-five percent of donor milk programs were ≤5 years old. Donor milk use occurred more often in hospitals with ≥1500 annual births (41.7%), compared to ≤500 annual births (6.3%) (adjusted odds ratio 7.8; 95% confidence interval 1.8-34.4), and in the west (30.9%), compared to the northeast (10.5%) (adjusted odds ratio 4.1; 95% confidence interval [1.1-14.9]).

CONCLUSIONS

Although there is limited evidence to support donor milk for healthy infants in the nursery, nearly one-fifth of level 1 US nurseries routinely used donor milk in 2017.

Alcohol Policies in U.S. States, 1999-2018

OBJECTIVE

U.S. policymakers and public health practitioners lack composite indicators (indices) to assess and compare the restrictiveness of state-level alcohol policy environments, conceptualized as the presence of multiple policies in effect in a particular place and time. The purposes of this study were to characterize the alcohol policy environment in each U.S. state and Washington, DC, in 2018, and to examine changes during the past 20 years.

METHOD

State-specific Alcohol Policy Scale (APS) scores from 1999 to 2018 were based on 29 policies, after weighting each present policy by its efficacy and degree of implementation. Modified APS scores were also calculated on the basis of two sets of mutually exclusive policy subgroups.

RESULTS

APS scores in 2018 varied considerably between states, ranging from 25.6 to 67.9 on a theoretical scale of 0 to 100; the median score was 43.5 (based on a 0-100 range), and 43 states had scores less than 50. The median change in state APS scores from 1999 to 2018 was positive (+4.9, range: -7.4 to +10.3), indicating increases in the restrictiveness of policy environments, with decreases in only five states. The increases in APS scores were primarily attributable to the implementation of stronger impaired-driving laws, whereas policies to reduce excessive drinking were unchanged. There was no correlation between states' excessive drinking policy scores and their impaired-driving scores (r = .05, p = .74).

CONCLUSIONS

Based on this policy scale, few states have restrictive policy environments. Although states adopted policies targeting impaired driving during the study period, there was no change in policies to reduce excessive drinking.

Loss Of SNAP Is Associated With Food Insecurity And Poor Health In Working Families With Young Children

The Supplemental Nutrition Assistance Program (SNAP) helps working families meet their nutritional needs. Families whose earned income increases in a given month may have their SNAP benefits abruptly reduced or cut off in the following month. Using sentinel sample data from 2007-15 for families with children younger than age four, we investigated how SNAP benefit reductions or cutoffs resulting from increased income were related to economic hardships (food and energy insecurity, unstable housing, forgone health and/or dental care, and health cost sacrifices) and to caregiver and child health. After we controlled for covariates, we found that the groups whose SNAP benefits were reduced or cut off had significantly increased odds of household and child food insecurity, compared to a group with consistent participation in SNAP. Reduced benefits were associated with 1.43 and 1.22 times greater odds of fair or poor caregiver and child health, respectively. Policy modifications to smooth changes in benefit levels as work incomes improve may protect working families with young children from increased food insecurity, poor health, and forgone care.

Medication for addiction treatment and acute care utilization in HIV-positive adults with substance use disorders

Medication for addiction treatment (MAT) could reduce acute care utilization in HIV-positive individuals with substance use disorders. The study objective was to determine if HIV-positive people with substance use disorders treated with MAT report less acute care utilization than those not receiving MAT. We assessed the association between MAT and acute care utilization among HIV-positive individuals with alcohol or opioid use disorder. Acute care utilization 6 months later was defined as any past 3-month self-reported (1) emergency department (ED) visit and (2) hospitalization. Of 153 participants, 88% had alcohol use disorder, 41% had opioid use disorder, and 48 (31%) were treated with MAT. Fifty-five (36%) participants had an ED visit and 38 (25%) participants had a hospitalization. MAT was not associated with an ED visit (AOR 1.12, 95% CI 0.46-2.75) or hospitalization (AOR 1.09, 95% CI 0.39-3.04). MAT was not associated with acute care utilization. These results highlight the need to increase MAT prescribing in HIV-positive individuals with substance use disorders, and to address the many factors that influence acute care utilization.

Food insecurity and substance use in people with HIV infection and substance use disorder

BACKGROUND

Food insecurity and substance use are common among people living with HIV (PLWH). Substance use may help people cope with hunger and thus be associated with food insecurity, but the association is uncertain. This study assessed whether, in PLWH and substance dependence, if there was an association between food insecurity and substance use.

Methods: We studied adults with HIV and current substance dependence or ever injection drug use interviewed at 12 and 24 months after enrollment in a prospective cohort study. The presence of food insecurity (insufficient food quantity or quality, or anxiety about its availability) was assessed using the Household Food Insecurity Assessment Scale questionnaire (HFIAS). Unhealthy alcohol use was assessed with the Alcohol Use Disorder Identification Test - Consumption (AUDIT-C) and past 30-day other drug use with the Addiction Severity Index. Associations using repeat cross-sectional data from each of two time-points, 12 months apart, from the same participants were tested using generalized estimating equations logistic regressions.

Results: The 233 participants had a mean age of 50 years and 65% were male. At the first interview, 44% reported food insecurity, 40% unhealthy alcohol use, 25% past 30-day cocaine use, and 17% past 30-day illicit opioid use. In analyses adjusted for demographics, social factors, physical and mental health function, and substance use related variables, there was no significant association between food insecurity and unhealthy alcohol use (adjusted odds ratio (aOR) = 1.06 (95% CI: 0.59, 1.87)). Those with food insecurity had higher odds of illicit opioid use (aOR = 2.5 (95% CI: 1.12, 5.58)) and cocaine use (aOR = 1.95 (CI 95%: 1.00, 3.81)).

Conclusion: Food insecurity was not associated with unhealthy alcohol use but was associated with cocaine and illicit opioid use. Given the prevalence and impact substance use has on PLWH, food insecurity should be identified and addressed.

Alcohol Policies and Motor Vehicle Crash Deaths Involving Blood Alcohol Concentrations Below 0.08

INTRODUCTION

Motor vehicle crashes are a leading cause of injury death in the U.S. Restrictive alcohol policies protect against crashes involving alcohol above the legal blood alcohol concentration of 0.08%. Characteristics of motor vehicle crash fatalities involving blood alcohol concentrations below the limit and their relationships to alcohol control policies have not been well characterized.

METHODS

Motor vehicle crash fatality data and crash and decedent characteristics from 2000 to 2015 came from the Fatality Analysis Reporting System and were analyzed in 2018-2019. Alcohol Policy Scale scores characterized alcohol policy environments by state-year. Generalized estimating equation alternating logistic regression models assessed these scores and the odds that a fatality involved alcohol below the legal threshold.

RESULTS

Of 612,030 motor vehicle crash fatalities, 223,471 (37%) died in alcohol-involved crashes, of which 33,965 (15% of alcohol-involved fatalities or 6% of all fatalities) had a blood alcohol concentration <0.08%. A 10 percentage point increase in Alcohol Policy Scale score, approximating the interquartile range among states, was associated with reduced odds of fatalities involving alcohol <0.08% vs 0.00% (AOR=0.91, 95% CI=0.89, 0.93). These findings held across multiple subgroup analyses by decedent and crash characteristics. Similar results were found for odds of alcohol involvement <0.05% vs 0.00% (AOR=0.90, 95% CI=0.88, 0.93), and ≥0.05% but <0.08% vs <0.05% (AOR=0.93, 95% CI=0.89, 0.96).

CONCLUSIONS

The number of lower blood alcohol concentration fatalities is substantial. States with more restrictive alcohol policies tend to have reduced odds of lower blood alcohol concentration motor vehicle crashes than states with weaker policies.

Alcohol and Bone Turnover Markers among People Living with HIV and Substance Use Disorder

BACKGROUND

Although unhealthy alcohol use and low bone density are prevalent among people living with HIV (PLWH), it is not clear whether alcohol use is associated with bone turnover markers (BTMs), and if so, at what quantity and frequency. The study objective was to examine the association between alcohol and BTMs in PLWH with substance use disorder.

METHODS

We studied a prospective cohort recruited from 2 HIV clinics who met criteria for DSM-IV substance dependence or reported ever injection drug use. Outcomes were BTM of (i) bone formation (serum procollagen type 1 N-terminal propeptide [P1NP]) and (ii) bone resorption (serum C-telopeptide type 1 collagen [CTx]). Alcohol consumption measures included (i) mean number of drinks/d (Timeline Follow-Back [TLFB]) (primary predictor), (ii) any alcohol use on ≥20 of the past 30 days, and phosphatidylethanol (PEth), a biomarker of recent alcohol consumption. Linear regression analysis examined associations between (i) each alcohol measure and each BTM and (ii) change in alcohol and change in BTM over 12 months.

RESULTS

Among 198 participants, baseline characteristics were as follows: The median age was 50 years; 38% were female; 93% were prescribed antiretroviral medications; 13% had ≥20 drinking days/month; mean drinks/day was 1.93 (SD 3.89); change in mean drinks/day was -0.42 (SD 4.18); mean P1NP was 73.1 ng/ml (SD 34.5); and mean CTx was 0.36 ng/ml (SD 0.34). Higher drinks/day was significantly associated with lower P1NP (slope -1.09 ng/ml; 95% confidence interval [CI] -1.94, -0.23, per each additional drink). On average, those who drank on ≥ 20 days/month had lower P1NP (-15.45 ng/ml; 95% CI: -26.23, -4.67) than those who did not. Similarly, PEth level ≥ 8ng/ml was associated with lower P1NP. An increase in drinks/d was associated with a decrease in P1NP nonsignificantly (-1.14; 95% CI: -2.40, +0.12; p = 0.08, per each additional drink). No significant associations were detected between either alcohol measure and CTx.

CONCLUSIONS

In this sample of PLWH with substance use disorder, greater alcohol consumption was associated with lower serum levels of bone formation markers.

Do Differences in Learning Performance Precede or Follow Initiation of Marijuana Use?

OBJECTIVE

Studies examining cross-sectional associations between age at marijuana initiation and memory deficits yield mixed results. Because longitudinal data are sparse, controversy continues regarding whether these deficits reflect premorbid risk factors or sequelae of early marijuana initiation; here, we examine this question in a community sample followed since birth.

METHOD

Masked examiners administered four subtests of the Wide Range Assessment of Memory and Learning (WRAML/WRAML2) from childhood until young adulthood to 119 urban, predominantly African American participants. Multivariable generalized estimated equation models measured longitudinal trajectories of learning. Participants were grouped as never users (n = 26), later initiators (≥16 years old; n = 31), and earlier initiators of marijuana use (n = 62).

RESULTS

Marijuana onset groups did not significantly differ on WRAML scaled scores or IQ in childhood, nor did they differ on WRAML scaled scores in adolescence. On most WRAML2 subtests, these groups did not significantly differ in young adulthood after taking into account sex and childhood IQ. However, on Story Memory, later initiators attained higher scaled scores in young adulthood, even after including additional covariates of anxiety, depression, postsecondary education, past-month marijuana use, and past-week high-risk drinking. They showed a significantly more positive trajectory than never users that was driven by within-group improvement after adolescence. Earlier initiators showed within-group decline in Story Memory after adolescence.

CONCLUSIONS

Differences in learning following earlier initiation of marijuana use may not be solely attributable to premorbid deficits.

Alcohol Policies in U.S. States, 1999-2018

OBJECTIVE

U.S. policymakers and public health practitioners lack composite indicators (indices) to assess and compare the restrictiveness of state-level alcohol policy environments, conceptualized as the presence of multiple policies in effect in a particular place and time. The purposes of this study were to characterize the alcohol policy environment in each U.S. state and Washington, DC, in 2018, and to examine changes during the past 20 years.

METHOD

State-specific Alcohol Policy Scale (APS) scores from 1999 to 2018 were based on 29 policies, after weighting each present policy by its efficacy and degree of implementation. Modified APS scores were also calculated on the basis of two sets of mutually exclusive policy subgroups.

RESULTS

APS scores in 2018 varied considerably between states, ranging from 25.6 to 67.9 on a theoretical scale of 0 to 100; the median score was 43.5 (based on a 0-100 range), and 43 states had scores less than 50. The median change in state APS scores from 1999 to 2018 was positive (+4.9, range: -7.4 to +10.3), indicating increases in the restrictiveness of policy environments, with decreases in only five states. The increases in APS scores were primarily attributable to the implementation of stronger impaired-driving laws, whereas policies to reduce excessive drinking were unchanged. There was no correlation between states' excessive drinking policy scores and their impaired-driving scores (r = .05, p = .74).

CONCLUSIONS

Based on this policy scale, few states have restrictive policy environments. Although states adopted policies targeting impaired driving during the study period, there was no change in policies to reduce excessive drinking.

Assessing the Role of Selection Bias in the Protective Relationship Between Caregiving and Mortality

Caregivers have lower mortality rates than noncaregivers in population-based studies, which contradicts the caregiver-stress model and raises speculation about selection bias influencing these findings. We examined possible selection bias due to 1) sampling decisions and 2) selective participation among women (baseline mean age = 79 years) in the Caregiver-Study of Osteoporotic Fractures (Caregiver-SOF) (1999-2009), an ancillary study to the Study of Osteoporotic Fractures (SOF). Caregiver-SOF includes 1,069 SOF participants (35% caregivers) from 4 US geographical areas (Baltimore, Maryland; Minneapolis, Minnesota; the Monongahela Valley, Pennsylvania; and Portland, Oregon). Participants were identified by screening all SOF participants for caregiver status (1997-1999; n = 4,036; 23% caregivers) and rescreening a subset of caregivers and noncaregivers matched on sociodemographic factors 1-2 years later. Adjusted hazard ratios related caregiving to 10-year mortality in all women initially screened, subsamples representing key points in constructing Caregiver-SOF, and Caregiver-SOF. Caregivers had better functioning than noncaregivers at each screening. The association between caregiving and mortality among women invited to participate in Caregiver-SOF (41% died; adjusted hazard ratio (aHR) = 0.73, 95% confidence interval (CI): 0.61, 0.88) was slightly more protective than that in all initially screened women (37% died; aHR = 0.83, 95% CI: 0.73, 0.95), indicating little evidence of selection bias due to sampling decisions, and was similar to that in Caregiver-SOF (39% died; aHR = 0.71, 95% CI: 0.57, 0.89), indicating no participation bias. These results add to a body of evidence that informal caregiving may impart health benefits.

SNAP, Young Children's Health, and Family Food Security and Healthcare Access

INTRODUCTION

The Supplemental Nutrition Assistance Program (SNAP) is the largest nutrition assistance program in the U.S. This study's objective was to examine the associations between SNAP participation and young children's health and development, caregiver health, and family economic hardships.

METHODS

Cross-sectional data from 2006 to 2016 were analyzed in 2017 for families with children aged <3 years in 5 cities. Generalized estimating equations and logistic regression were used to evaluate the associations of SNAP participation with child and caregiver health outcomes and food insecurity, forgone health care, and health cost sacrifices. Nonparticipants that were likely to be eligible for SNAP were compared with SNAP participants and analyses adjusted for covariates including Consumer Price Index for food to control for site-specific food prices.

RESULTS

The adjusted odds of fair or poor child health status (AOR=0.92, 95% CI=0.86, 0.98), developmental risk (AOR=0.82, 95% CI=0.69, 0.96), underweight, and obesity in children were lower among SNAP participants than among nonparticipants. In addition, food insecurity in households and among children, and health cost sacrifices were lower among SNAP participants than among nonparticipants.

CONCLUSIONS

Participation in SNAP is associated with reduced household and child food insecurity, lower odds of poor health and growth and developmental risk among infants and toddlers, and reduced hardships because of healthcare costs for their families. Improved SNAP participation and increased SNAP benefits that match the regional cost of food may be effective preventive health strategies for promoting the well-being of families with young children.

Twelve-Month Outcomes of a Group-Randomized Community Health Advocate-Led Smoking Cessation Intervention in Public Housing

Background

Lower rates of smoking cessation are a major reason for the higher prevalence of smoking among socioeconomically disadvantaged adults. Because barriers to quitting are both more numerous and severe, socioeconomically disadvantaged smokers may benefit from more intensive intervention. We sought to determine whether a smoking cessation intervention delivered by public housing residents trained as Tobacco Treatment Advocates (TTAs) could increase utilization of cessation resources and increase abstinence.

Methods

We conducted a group-randomized trial among Boston public housing residents who were interested in quitting smoking. Participants at control sites received standard cessation materials and a one-time visit from a TTA who provided basic counseling and information about cessation resources. Participants at intervention sites were eligible for multiple visits by a TTA who employed motivational interviewing, cessation counseling, and navigation to encourage smokers to utilize cessation treatment (Smokers' Quitline and clinic-based programs). Utilization and 7-day and 30-day point prevalence abstinence were assessed at 12 months. Self-reported abstinence was biochemically verified.

Results

Intervention participants (n = 121) were more likely than control participants (n = 129) to both utilize treatment programs (adjusted odds ratio [aOR]: 2.15; 95% confidence interval [CI]: 0.93-4.91) and 7-day and 30-day point prevalence abstinence (aOR: 2.60 (1.72-3.94); 2.98 (1.56-5.68), respectively). Mediation analysis indicated that the higher level of utilization did not explain the intervention effect.

Conclusions

An intervention delivered by peer health advocates was able to increase utilization of treatment programs and smoking abstinence among public housing residents. Future studies of similar types of interventions should identify the key mechanisms responsible for success.

Implications

In order to narrow the large and growing socioeconomic disparity in smoking rates, more effective cessation interventions are needed for low-income smokers. Individual culturally-relevant coaching provided in smokers' residences may help overcome the heightened barriers to cessation experienced by this group of smokers. In this study among smokers residing in public housing, an intervention delivered by peer health advocates trained in motivational interviewing, basic smoking cessation skills, and client navigation significantly increased abstinence at 12 months. Future research should address whether these findings are replicable in other settings both within and outside of public housing.

Comparison of novel methods in two-way enriched clinical trial design

Two-way enriched design (TED) is a novel approach addressing placebo response in clinical trials. It is a two-stage, randomized, placebo-controlled trial design with enrichment in placebo non-responders and treatment responders at the second stage. All data from the first stage and data from placebo non-responders and treatment responders in the second stage are used for the final analysis of the treatment effect. The existing methods for the analysis of TED data include score tests with one, two, and three degrees of freedom. All these methods are only applicable to binary outcomes. However, there is an interest in continuous outcomes in clinical trials in psychiatry. In this manuscript, we apply some novel methods, including a repeated measures model, a weighted repeated measures model with weights from propensity score, and weights from K-means clustering, to analyze TED data for both binary outcomes and continuous outcomes. The simulation study indicates that the repeated measures model performs consistently well in preserving the type I error and achieving the minimum mean standard error as well as a higher power. The performance of the weighted repeated measures model with weights from K-means clustering improves with increasing sample size. Investigators can choose from these analytic approaches under different scenarios.

Alcohol Policies and Alcohol Involvement in Intimate Partner Homicide in the U.S

INTRODUCTION

Intimate partner violence (IPV) results in deaths of both primary and corollary (i.e., nonintimate partner) victims. Alcohol use is a known risk factor for IPV, yet the relationship between alcohol policies and IPV homicides is unclear. This repeated cross-sectional study characterizes alcohol involvement, and the relationship between alcohol policies and alcohol involvement, among victims of IPV homicides in the U.S.

METHODS

Homicide victim data from 17 states in the National Violent Death Reporting System from 2003 to 2012 were analyzed in 2017-2018. Alcohol Policy Scale scores characterized alcohol policies by state year and were used in generalized estimating equation logistic regression models to predict the odds of alcohol involvement among victims of IPV homicide.

RESULTS

Among victims of IPV homicide, 36.5% of primary and 41.1% of corollary victims had a blood alcohol concentration (BAC) >0.00%. Of the victims with a positive BAC, 67.6% had a BAC ≥0.08%. In adjusted models, a 10-percentage point increase in Alcohol Policy Scale score was associated with reduced odds of having a positive BAC (AOR=0.77, 95% CI=0.64, 0.93) and having a BAC ≥0.08% (AOR=0.82, 95% CI=0.68, 0.99) among all victims, primary victims (AOR=0.78, 95% CI=0.63, 0.98; AOR=0.82, 95% CI=0.65, 1.04), and corollary victims (AOR=0.61, 95% CI=0.42, 0.89; AOR=0.68, 95% CI=0.48, 0.97).

CONCLUSIONS

Alcohol use was prevalent among victims of IPV homicide, and more-restrictive alcohol policies were associated with reduced odds of alcohol involvement. Strengthening alcohol policies is a promising strategy to reduce alcohol-involved IPV homicide victimization.

Neurocognitive and Health Correlates of Overweight and Obesity among Ten-Year-Old Children Born Extremely Preterm

OBJECTIVE

To assess the relationship between overweight (body mass index [BMI] percentile ≥85 and <95) and obesity (BMI ≥95 percentile) and developmental and health outcomes at 10 years of age in a cohort of individuals born extremely preterm.

STUDY DESIGN

This was an observational cohort study of children born extremely preterm and then assessed at age 10 years for neurocognitive function and parent-reported behavior and health outcomes. Participants included 871 children aged 10 years. To describe the strength of association between overweight or obesity and outcomes, we used logistic regression models adjusting for confounders. Neurocognitive function, academic achievement, parent-reported health outcome surveys, and height and weight were measured.

RESULTS

BMI category at 10 years of age was not associated with differences in intelligence, language, or academic achievement. Parents of children with obesity were more likely to report their child had asthma (OR 2.2; 95% CI 1.4-3.5), fair/poor general health (OR 3.2; 95% CI 1.4-7.5), and decreased physical function (OR 1.7; 95% CI 1.1-2.9) but less likely to have physician diagnosed attention-deficit/hyperactivity disorder (OR 0.5; 95% CI 0.3-0.97) or an individualized education plan (OR 0.6; 95% CI 0.4-0.99).

CONCLUSION

Among children born extremely preterm, an elevated BMI, compared with normal or low BMI, is not associated with a difference in neurocognitive function. However, asthma, fair/poor general health, and decreased physical function were more prevalent among study participants with obesity, and attention-deficit/hyperactivity disorder and individualized education plan were less prevalent.

Transitions To and From At-Risk Alcohol Use in Adults in the United States

Introduction

The objective of this research was to study transitions to and from at-risk alcohol use.

Methods

Logistic regression analyses (done 2015-2016) assessed transitions to and from past-year at-risk drinking in a representative sample of U.S. adults surveyed twice (in 2001-2 and 2004-5).

Results

Among 34,653 adults, 28% reported at-risk use at time 1. Of those, 73% had at-risk use at time 2. Of those without at-risk use at time 1, 15% reported at-risk use at time 2. Positive high-risk drinking transition predictors were, at time 1, being young, male, white, childless, in good to excellent health, ever smoking, using drugs, military membership (time 1 but not 2), and becoming divorced or separated by time 2. Positive low-risk drinking transition predictors were being elderly (age ≥65), female, non-white, never smoking or using drugs, no alcohol use disorder, alcohol treatment, and, after time 1, having children.

Conclusions

Many adults transition to and from at-risk alcohol use; youth is the strongest positive predictor of transition to at-risk and not transitioning to low-risk drinking. Persons transitioning to legal drinking age are most likely to transition to high-risk and least likely to low-risk drinking.

Association of State Alcohol Policies With Alcohol-Related Motor Vehicle Crash Fatalities Among US Adults

IMPORTANCE

Motor vehicle crashes are a leading cause of mortality. However, the association between the restrictiveness of the alcohol policy environment (ie, based on multiple existing policies) and alcohol-related crash fatalities has not been characterized previously to date.

OBJECTIVE

To examine the association between the restrictiveness of state alcohol policy environments and the likelihood of alcohol involvement among those dying in motor vehicle crashes in the United States.

DESIGN, SETTING, AND PARTICIPANTS

This investigation was a repeated cross-sectional study in which state alcohol policies (operationalized by the Alcohol Policy Scale [APS]) from 1999 to 2014 were related to motor vehicle crash fatalities from 2000 to 2015 using data from the Fatality Analysis Reporting System (1-year lag). Alternating logistic regression models and generalized estimating equations were used to account for clustering of multiple deaths within a crash and of multiple crashes occurring within states. The study also examined independent associations of mutually exclusive subgroups of policies, including consumption-oriented policies vs driving-oriented policies. The study setting was the 50 US states. Participants were 505 614 decedents aged at least 21 years from motor vehicle crashes from 2000 to 2015.

MAIN OUTCOMES AND MEASURES

Odds that a crash fatality was alcohol related (fatality stemmed from a crash in which ≥1 driver had a blood alcohol concentration [BAC] ≥0.08%).

RESULTS

From 2000 to 2015, there were 505 614 adult motor vehicle crash fatalities in the United States, of which 178 795 (35.4%) were alcohol related. Each 10-percentage point increase in the APS score (corresponding to more restrictive state policies) was associated with reduced individual-level odds of alcohol involvement in a crash fatality (adjusted odds ratio [aOR], 0.90; 95% CI, 0.89-0.91); results were consistent among most demographic and crash-type strata. More restrictive policies also had protective associations with alcohol involvement among crash fatalities associated with BACs from greater than 0.00% to less than 0.08%. After accounting for driving-oriented policies, consumption-oriented policies were independently protective for alcohol-related crash fatalities (aOR, 0.97; 95% CI, 0.96-0.98 based on a 10-percentage point increased APS score).

CONCLUSIONS AND RELEVANCE

Strengthening alcohol policies, including those that do not specifically target impaired driving, could reduce alcohol-related crash fatalities. Policies may also protect against crash fatalities involving BAC levels below the current legal limit for driving in the United States.

Alcohol Consumption and Bone Mineral Density in People with HIV and Substance Use Disorder: A Prospective Cohort Study

BACKGROUND

People living with HIV (PLWH) commonly have low bone mineral density (BMD) (low bone mass and osteoporosis) and are at high risk for fractures. Fractures and low BMD are significant causes of morbidity and mortality, increasingly relevant as PLWH age. Alcohol use is common among PLWH and known to affect bone health. The association between alcohol use and changes in BMD among PLWH is not well understood.

METHODS

We conducted a 3.5-year prospective cohort study of 250 PLWH with substance use disorder or ever injection drug use. Annual alcohol consumption was measured as a mean of grams per day of alcohol, mean number of heavy drinking days per month, mean number of days abstinent per month, and any heavy drinking, using the 30-day Timeline Followback method twice each year. The primary outcome was annual change in BMD measured each year by dual energy X-ray absorptiometry in grams per square centimeter (g/cm2 ) at the femoral neck. Additional dependent variables included annual change in total hip and lumbar spine BMD, >6% annual decrease in BMD at any site, and incident fractures in the past year. Regression models adjusted for relevant covariates.

RESULTS

The median age of participants was 50 years. The median duration of HIV infection was 16.5 years and the mean time since antiretroviral therapy initiation was 12.3 years. At study entry, 67% of participants met criteria for low BMD (46% low bone mass, 21% osteoporosis). Median follow-up was 24 months. We found no significant associations between any measure of alcohol consumption and changes in BMD (g/cm2 ) at the femoral neck (adjusted β for g/d of alcohol = -0.0032, p = 0.7487), total hip, or lumbar spine. There was no significant association between any measure of alcohol consumption and >6% annual decrease in BMD at any site, or incident fractures.

CONCLUSIONS

In this sample of PLWH and substance use disorders or ever injection drug use, we detected no association between any of the alcohol measures used in the study and changes in BMD or incident fractures.

Childhood Trauma Questionnaire (CTQ) correlations with prospective violence assessment in a longitudinal cohort

Retrospective recall-based measures administered to adults, like the Childhood Trauma Questionnaire (CTQ), are commonly used to determine experiences of childhood trauma in the home. However, the CTQ has not been compared with prospective measures of childhood violence exposure, whether at home or in the community. We evaluated the relationships between young adults' responses to the CTQ and their prospective self-reports of exposure to violence in childhood and adolescence. Participants were 127 (93% African American, 47% male) urban young adults in a longitudinal birth cohort study examining effects of prenatal substance exposure and environmental factors on development. Participants completed the Violence Exposure Scale for Children-Revised (VEX-R), a 21-item self-report measure of experience of/witness to interpersonal violence, administered face to face at 9, 10, and 11 years using cartoon pictures, and via audio-computer assisted self-interview at 12, 14, and 16 years. Participants also completed the CTQ, a 28-item, 5-scale screening measure, during a young-adult follow-up (ages 18-23). Using Pearson Correlation coefficients, VEX-R total scores significantly correlated with the sum of CTQ scales, r = .33, p < .01, and 3 (physical, emotional, and sexual abuse) of the 5 CTQ subscales, showing a moderate linear association. This study suggests that the CTQ serves as a reasonable retrospective assessment of prospectively ascertained childhood trauma exposure. The differences may be accounted for by disparities in domains assessed. (PsycINFO Database Record

Differences in Caregiving Outcomes and Experiences by Sexual Orientation and Gender Identity

PURPOSE

The purpose of this study was to determine whether caregiving experiences and their health-related outcomes differ by sexual orientation and gender identity in a representative U.S. caregiver sample.

METHODS

A secondary data analysis was performed of the cross-sectional, nationally representative National Alliance for Caregiving online survey that was conducted in 2014. To account for the study design, we used sampling weights and then added propensity score weighting to account for imbalances between LGBT respondents and their heterosexual and cisgender counterparts, that is, non-LGBT caregivers. Outcomes consisted of caregivers' self-reported health, financial strain, physical strain, and emotional stress.

RESULTS

LGBT caregivers were significantly younger, more racially and ethnically diverse, less likely to be married, and more likely to be of low socioeconomic status than their non-LGBT counterparts. Caregiving experiences and intensity were similar, but after controlling for demographic and caregiving characteristics, LGBT caregivers were significantly more likely to report financial strain and showed trends toward elevated levels of poor health and emotional stress. Physical strain was similar by LGBT status.

CONCLUSION

Caregiving itself is universal, yet LGBT caregivers differed demographically and were more likely to report financial strain compared with non-LGBT caregivers.

Lifetime marijuana and alcohol use, and cognitive dysfunction in people with human immunodeficiency virus infection

BACKGROUND

Substance use is common among people with human immunodeficiency virus (HIV) infection. Alcohol, marijuana, and HIV can have negative effects on cognition. Associations between current and lifetime marijuana and alcohol use and cognitive dysfunction in people with HIV infection were examined.

METHODS

Some 215 HIV-infected adults with Diagnostic and Statistical Manual of Mental Disorders Fourth Edition (DSM-IV) substance dependence or ever injection drug use were studied. In adjusted cross-sectional regression analyses associations were assessed between current marijuana use, current heavy alcohol use, lifetime marijuana use, lifetime alcohol use, duration of heavy alcohol use (the independent variables), and 3 measures of cognitive dysfunction (dependent variables): both the (i) memory and (ii) attention domains from the Montreal Cognitive Assessment (MoCA) and the (iii) 4-item cognitive function scale (CF4) from the Medical Outcomes Study HIV Health Survey (MOS-HIV). Analyses were adjusted for demographics, primary language, depressive symptoms, anxiety, comorbidities, antiretroviral therapy, hepatitis C virus (ever), duration of HIV infection (years), HIV-viral load (log copies/mL), CD4 cell count, lifetime and recent cocaine use, and recent illicit and prescribed opioid use.

RESULTS

Current marijuana use was significantly and negatively associated with the MOS-HIV CF4 score (adjusted mean difference = -0.40, P = .01). Current marijuana use was not significantly associated with either MoCA score. Lifetime marijuana use and current heavy and lifetime alcohol use and duration of heavy alcohol use were not associated with any measure of cognitive dysfunction.

CONCLUSION

Current marijuana use was associated with one measure of cognitive dysfunction, but there was not a consistent pattern of association with lifetime marijuana use or alcohol use and measures of cognitive dysfunction. Understanding the mechanism by which marijuana, with and without alcohol, are associated with worse cognition warrants larger, longer studies with more precise and diverse measurements of cognitive function.

Trust in Sources of Advice about Infant Care Practices: The SAFE Study

Objectives (1) Determine the prevalence of maternal trust in advice sources on infant care practices; (2) Investigate the association of maternal and infant characteristics with trust in advice sources on infant care practices. Methods Using probability sampling methods, we recruited mothers from 32 U.S. maternity hospitals with oversampling of Black and Hispanic women resulting in a nationally representative sample of mothers of infants aged 2-6 months. Survey questions assessed maternal trust in advice sources (physicians, nurses, family, friends, and media) regarding infant care practices including infant sleep practices (sleep position, bed sharing, and pacifier use), feeding, and vaccination. Weighted frequencies of maternal trust in advice sources were calculated to obtain prevalence estimates. Multivariable logistic regression was used to assess the association of maternal and infant characteristics with maternal trust in advice sources. Results Mothers had the greatest trust in doctors for advice on all infant care practices (56-89 %), while trust was lowest for friends (13-22 %) and the media (10-14 %). In the adjusted analyses, there were significant associations of maternal race/ethnicity, education, and age with trust in advice sources. Conclusions for Practice Maternal trust in advice about infant care practices varied significantly by source. A better understanding of which advice sources are most trusted by mothers, as well as the factors associated with maternal trust, may guide the development of more effective strategies to improve adherence to health promoting infant care practices.

Polypharmacy and risk of falls and fractures for patients with HIV infection and substance dependence

Although people with HIV infection (PLWH) are at higher risk of polypharmacy and substance use, there is limited knowledge about potential harms associated with polypharmacy such as falls and fractures in this population. The study objective was to determine whether polypharmacy, as measured by the number and type of medication, is associated with falls and fractures among PLWH and DSM-IV substance dependence in the past year or ever injection drug use (IDU). We identified the number of medications by electronic medical record review in the following categories: (i) systemically active, (ii) non-antiretroviral (non-ARV), (iii) sedating, (iv) non-sedating as well as any opioid medication and any non-opioid sedating medication. Outcomes were self-reported (1) fall/accident requiring medical attention and (2) fracture in the previous year. Separate logistic regression models were fitted for medications in each category and each outcome. Among 250 participants, the odds of a fall requiring medical attention were higher with each additional medication overall (odds ratio [OR] 1.12, 95% Confidence Interval [CI] = 1.05, 1.18), each additional non-ARV medication (OR 1.13, 95%CI = 1.06, 1.20), each additional sedating medication (OR 1.36, 95%CI = 1.14, 1.62), and a non-opioid sedating medication (OR 2.89, 95%CI = 1.06, 7.85) but not with an additional non-sedating medication or opioid medication. In receiver operating characteristic (ROC) curve analyses, optimal cutoffs for predicting falls were: ≥8 overall and ≥2 sedating medications. Odds ratios for fracture in the previous year were OR 1.05, 95%CI = 0.97, 1.13 for each additional medication overall and OR 1.11, 95%CI = 0.89, 1.38 for each additional sedating medication. In PLWH and substance dependence or ever IDU, a higher number of medications was associated with greater odds of having a fall requiring medical attention. The association appeared to be driven largely by sedating medications. Future studies should determine if reducing such polypharmacy, particularly sedating medications, lowers the risk of falls.

Predictors of Maternal Trust in Doctors About Advice on Infant Care Practices: The SAFE Study

OBJECTIVE

To determine predictors of maternal trust in doctors about advice on infant care practices.

METHODS

Using probability sampling methods, we recruited mothers from 32 US maternity hospitals. Mothers completed a survey 2 to 6 months postpartum that included questions about maternal trust in doctors regarding 6 infant care practices and physician characteristics (doctor asked mother's opinion, doctor is qualified, infant sees 1 main doctor who is/is not of the same ethnicity/race). Prevalence estimates and 95% confidence intervals were calculated for maternal trust in physician advice for each infant care practice. Multivariate logistic regression was used to calculate the independent association of maternal and physician characteristics and trust for each infant care practice, controlling for sociodemographic characteristics.

RESULTS

Of the 3983 mothers enrolled from January 2011 to March 2014, 3297 (83%) completed the follow-up survey. Maternal trust in the doctor varied according to infant care practice with highest trust for vaccination (89%) and lowest trust for pacifier use (56%). In the adjusted analyses, for all infant care practices, mothers were more likely to trust their doctors if they reported that the doctors were qualified (adjusted odds ratio [AOR], >3.0 for all practices) or if the doctor had asked their opinion (AOR, 1.76-2.43). For mothers who reported seeing 1 main doctor, white mothers were more likely to trust physicians for almost all infant care practices if they reported the doctor was the same race (AOR, 1.54-2.19).

CONCLUSIONS

Physician characteristics and ways of communication were significantly associated with maternal trust in doctors about advice on infant care practices.

Alcohol Policies and Alcohol-Involved Homicide Victimization in the United States

OBJECTIVE

The purpose of this study was to examine the associations between the alcohol policy environment and alcohol involvement in homicide victims in the United States, overall and by sociodemographic groups.

METHOD

To characterize the alcohol policy environment, the presence, efficacy, and degree of implementation of 29 alcohol policies were used to determine Alcohol Policy Scale (APS) scores by state and year. Data about homicide victims from 17 states from 2003 to 2012 were obtained from the National Violent Death Reporting System. APS scores were used as lagged exposure variables in generalized estimating equation logistic regression models to predict the individual-level odds of alcohol involvement (i.e., blood alcohol concentration [BAC] > 0.00% vs. = 0.00% and BAC ≥ 0.08% vs. ≤ 0.079%) among homicide victims.

RESULTS

A 10 percentage point increase in APS score (representing a more restrictive policy environment) was associated with reduced odds of alcohol-involved homicide with BAC greater than 0.00% (adjusted odds ratio [AOR] = 0.89, 95% CI [0.82, 0.99]) and BAC of 0.08% or more (AOR = 0.91, 95% CI [0.82, 1.02]). In stratified analyses of homicide victims, more restrictive policy environments were significantly protective of alcohol involvement at both BAC levels among those who were female, ages 21-29 years, Hispanic, unmarried, victims of firearm homicides, and victims of homicides related to intimate partner violence.

CONCLUSIONS

More restrictive alcohol policy environments were associated with reduced odds of alcohol-involved homicide victimization overall and among groups at high risk of homicide. Strengthening alcohol policies is a promising homicide prevention strategy.

Cumulative Incidence of Seizures and Epilepsy in Ten-Year-Old Children Born Before 28 Weeks' Gestation

OBJECTIVE

We evaluated the incidence of seizures and epilepsy in the first decade of life among children born extremely premature (less than 28 weeks' gestation).

METHOD

In a prospective, multicenter, observational study, 889 of 966 eligible children born in 2002 to 2004 were evaluated at two and ten years for neurological morbidity. Complementing questionnaire data to determine a history of seizures, all caregivers were interviewed retrospectively for postneonatal seizures using a validated seizure screen followed by a structured clinical interview by a pediatric epileptologist. A second pediatric epileptologist established an independent diagnosis based on recorded responses of the interview. A third epileptologist determined the final diagnosis when evaluators disagreed (3%). Life table survival methods were used to estimate seizure incidence through ten years.

RESULTS

By age ten years, 12.2% (95% confidence interval: 9.8, 14.5) of children had experienced one or more seizures, 7.6% (95% confidence interval: 5.7, 9.5) had epilepsy, 3.2% had seizure with fever, and 1.3% had a single, unprovoked seizure. The seizure incidence increased with decreasing gestational age. In more than 75% of children with seizures, onset was after one year of age. Seizure incidence was comparable in both sexes. Two-thirds of those with epilepsy had other neurological disorders. One third of children with epilepsy were not recorded on the medical history questionnaire.

SIGNIFICANCE

The incidence of epilepsy through age ten years among children born extremely premature is approximately 7- to 14-fold higher than the 0.5% to 1% lifetime incidence reported in the general pediatric population. Seizures in this population are under-recognized, and possibly underdiagnosed, by parents and providers.

Polypharmacy and risk of non-fatal overdose for patients with HIV infection and substance dependence

INTRODUCTION

People living with HIV (PLWH) are at risk of both polypharmacy and unintentional overdose yet there are few data on whether polypharmacy increases risk of overdose. The study objective was to determine if the number and type of medication (e.g., sedating) were associated with non-fatal overdose (OD) among PLWH with past-year substance dependence or a lifetime history of injection drug use.

MATERIALS AND METHODS

This was a longitudinal study of adults recruited from two urban, safety-net HIV clinics. Outcomes were i) lifetime and ii) past-year non-fatal OD assessed at baseline and a 12-month follow-up. We used logistic regression to examine the association between each outcome and the number of medications (identified from the electronic medical record) in the following categories: i) overall medications, ii) non-antiretroviral (non-ARV), iii) sedating, iv) non-sedating, as well as any vs no opioid medication and any vs no non-opioid sedating medication. Covariates included demographics, medical comorbidities, depressive and anxiety symptoms, and substance use.

RESULTS

Among 250 participants, 80% were prescribed a sedating medication, 50% were prescribed an opioid; 51% exceeded risky drinking limits. In the past month, 23% reported illicit opioid use and 9% illicit opioid sedative use; 37% reported lifetime non-fatal OD and 7% past-year non-fatal OD. The median number (interquartile range) of total medications was 10 (7, 14) and 2 (1, 3) sedating. The odds of lifetime non-fatal OD were significantly higher with each additional sedating medication (OR 1.26, 95% CI 1.08, 1.46) and any opioid medication (OR 2.31; 95% CI 1.37, 3.90), but not with each overall, non-ARV, or non-sedating medication. The odds of past year non-fatal OD were greater with each additional sedating medication (OR 1.18; 95% CI 1.00, 1.39, p=0.049), each additional non-ARV medication (OR 1.07; 95% CI 1.00, 1.15, p=0.048), and non-significantly for any opioid medication (OR 2.23; 95% CI 0.93, 5.35).

CONCLUSIONS

In this sample of PLWH with substance dependence and/or injection drug use, number of sedating medications and any opioid were associated with non-fatal overdose; sedating medications were prescribed to the majority of patients. Polypharmacy among PLWH and substance dependence warrants further research to determine whether reducing sedating medications, including opioids, lowers overdose risk.

Intrauterine exposure to tobacco and executive functioning in high school

BACKGROUND

Executive functioning (EF), an umbrella construct encompassing gradual maturation of cognitive organization/management processes, is important to success in multiple settings including high school. Intrauterine tobacco exposure (IUTE) correlates with negative cognitive/behavioral outcomes, but little is known about its association with adolescent EF and information from real-life contexts is sparse. We evaluated the impact of IUTE on teacher-reported observations of EF in urban high school students controlling for covariates including other intrauterine and adolescent substance exposures.

METHODS

A prospective low-income birth cohort (51% male; 89% African American/Caribbean) was followed through late adolescence (16-18 years old). At birth, intrauterine exposures to cocaine and other substances (52% cocaine, 52% tobacco, 26% marijuana, 26% alcohol) were identified by meconium and/or urine assays, and/or maternal self-report. High school teachers knowledgeable about the student and unaware of study aims were asked to complete the Behavior Rating Inventory of Executive Functioning-Teacher Form (BRIEF-TF) annually.

RESULTS

Teachers completed at least one BRIEF-TF for 131 adolescents. Multivariable analyses included controls for: demographics; intrauterine cocaine, marijuana, and alcohol exposures; early childhood exposures to lead; and violence exposure from school-age to adolescence. IUTE was associated with less optimal BRIEF-TF Behavioral Regulation scores (p <0.05). Other intrauterine substance exposures did not predict less optimal BRIEF-TF scores, nor did exposures to violence, lead, nor adolescents' own substance use.

CONCLUSIONS

IUTE is associated with offspring's less optimal EF. Prenatal counseling should emphasize abstinence from tobacco, as well as alcohol and illegal substances.

Maternal Attitudes and Other Factors Associated with Infant Vaccination Status in the United States, 2011-2014

OBJECTIVE

To assess the role of maternal attitudes and other factors associated with infant vaccination status.

STUDY DESIGN

Data on reported vaccination status were analyzed from a nationally representative prospective survey of mothers of 2- to 6-month-old infants. Weighted univariate and multiple logistic regression analyses were conducted. Latent profile analysis of mothers reporting nonimmunized infants identified distinct groups, RESULTS: Of 3268 mothers, 2820 (weighted 86.2%), 311 (9.1%), and 137 (4.7%), respectively, reported their infant had received all, some, or no recommended vaccinations for age. Younger infants and infants with younger mothers were more likely to have received no vaccinations. Mothers with neutral and negative attitudes toward vaccination were >3 (aOR 3.66, 95% CI 1.80-7.46) and 43 times (aOR 43.23, 95% CI 20.28-92.16), respectively, more likely than mothers with positive attitudes to report their infants had received no vaccinations. Two subgroups of mothers reporting that their infants had received no vaccinations were identified: group A (52.5%) had less than positive attitudes and less than positive subjective norms about vaccination (ie, perceived social pressure from others); group B (47.5%) had positive attitudes and positive subjective norms. Group A mothers were more likely to be white (76.1% vs 48.3%, P?=?.002), more educated (43.5% vs 35.4% college or higher, P?=?.02), and to exclusively breastfeed (74.9% vs. 27.3%, P?<?.001).

CONCLUSIONS

Although access barriers can result in nonvaccination, less than positive maternal attitude toward vaccination was the strongest predictor. Strategies to improve vaccination rates must focus on both improved access and better understanding of factors underlying maternal attitudes.

HIV-infected individuals who use alcohol and other drugs, and virologic suppression

People living with HIV (PLWH) on antiretroviral therapy (ART) who use substances were examined to (a) describe those with virologic control and (b) determine which substance use-factors are associated with lack of virologic control. Participants were adult PLWH taking ART with either past 12-month DSM-IV substance dependence or past 30-day alcohol or illicit drug use. Substance use factors included number of DSM-IV alcohol or drug dependence criteria and past 30-day specific substance use. Associations with HIV viral load (HVL) (<200 vs. ≥200 copies/mL) were tested using logistic regression models. Multivariable analyses adjusted for age, sex, homelessness and anxiety or depression. Participants (n = 202) were median age 50 years, 66% male, 51% African American and 75% self-reported ≥90% past 30-day ART adherence. Though HVL suppression (HVL <200 copies/mL) was achieved in 78% (158/202), past 30-day substance use was common among this group: 77% cigarette use; 51% heavy alcohol use; 50% marijuana; 27% cocaine; 16% heroin; and 15% illicit prescription opioid use. After adjusting for covariates, specific substance use was not associated with a detectable HVL, however number of past 12-month DSM-IV drug dependence criteria was (adjusted odds ratio = 1.23 for each additional criterion, 95% CI: 1.04-1.46). Three-quarters of a substance-using cohort of PLWH receiving ART had virologic control and ≥90% ART adherence. Substance dependence criteria (particularly drug dependence), not specifically substance use, were associated with lack of virologic control. Optimal HIV outcomes can be achieved by individuals who use alcohol or drugs and addressing symptoms of substance dependence may improve HIV-related outcomes.

Lifetime and recent alcohol use and bone mineral density in adults with HIV infection and substance dependence

Low bone mineral density (BMD) is common in people living with HIV infection (PLWH), increasing fracture risk. Alcohol use is also common in PLWH and is a modifiable risk factor for both HIV disease progression and low BMD. In PLWH, alcohol's effect on BMD is not well understood.We studied adult PLWH with substance dependence. We measured lifetime alcohol use (kg) and recent (i.e., past 30-day) alcohol use (categorized as: abstinent, low risk, or high risk). In adjusted multivariable regression analyses, we tested associations between lifetime and recent alcohol use and (i) mean BMD (g/cm) at the femoral neck, total hip, and lumbar spine and (ii) low BMD diagnosis (i.e., osteopenia or osteoporosis). We also examined associations between 2 measures of past alcohol use (i.e., total consumption [kg] and drinking intensity [kg/year]) and BMD outcome measures during 3 periods of the HIV care continuum: (i) period before first positive HIV test, (ii) period from first positive HIV test to antiretroviral therapy (ART) initiation, and (iii) period following ART initiation.We found no significant associations between lifetime alcohol use and mean femoral neck (β -0.000, P = .62), total hip (β -0.000, P = .83) or lumbar spine (β 0.001, P = .65) BMD (g/cm), or low BMD diagnosis (adjusted odds ratio [aOR] = 0.98, 95% Confidence Interval [CI]: 0.95-1.01). There was no significant correlation between past 30-day alcohol use and mean BMD (g/cm). Past 30-day alcohol use was associated with low BMD diagnosis (P = .04); compared to abstainers, the aOR for high risk alcohol use was 1.94 (95% CI: 0.91-4.12), the aOR for low risk alcohol use was 4.32 (95% CI: 1.30-14.33). Drinking intensity (kg/year) between first positive HIV test and ART initiation was associated with lower mean BMD (g/cm) at the femoral neck (β -0.006, P = .04) and total hip (β -0.007, P = .02) and increased odds of low BMD (aOR = 1.18, 95% CI = 1.03-1.36).In this sample of PLWH, we detected no association between lifetime alcohol use and BMD. However, recent drinking was associated with low BMD diagnosis, as was drinking intensity between first positive HIV test and ART initiation. Longitudinal studies should confirm these associations.

Alcohol Policies and Alcohol-Related Motor Vehicle Crash Fatalities Among Young People in the US

BACKGROUND

Motor vehicle crashes (MVCs) are a leading cause of death among young people in the United States. We examined the relationship between states' alcohol policy environments and alcohol-related MVC fatalities among children, adolescents, and young adults under the minimum legal drinking age of 21 years.

METHODS

We used the Alcohol Policy Scale (APS), an assessment of 29 alcohol policies across 50 states and Washington, DC, developed with the assistance of an interdisciplinary Delphi panel. Using the Fatality Analysis Reporting System, we examined APS scores in relation to fatalities of people ≤20 years old from 2000 to 2013 occurring in crashes in which ≥1 involved driver had a blood alcohol content ≥0.08%. Logistic regression was used with a 1-year lag between policies and MVC fatalities and adjusted for potential confounders.

RESULTS

Of 84 756 MVC fatalities of those ≤20 years old during the study period, 23 757 (28.0%) were alcohol related, including deaths of 11 006 (46.3%) drivers, 10 212 (43.0%) passengers, and 2539 (10.7%) pedestrians, cyclists, and others. People killed in alcohol-related MVCs were predominantly male (72.7%) and older (65.5% were 18-20 years old), and 51.2% were non-Hispanic white. Restrictive policy environments were associated with fewer fatalities (adjusted odds ratio, 0.91 per 10-percentage-point increase in APS score; 95% confidence interval, 0.89-0.94). The association was observed for drivers and passengers, male and female decendents, and children, adolescents, and young adults.

CONCLUSIONS

More restrictive alcohol policies are associated with reduced alcohol-related MVC mortality among young people. Studies should scrutinize the relationship between policies and fatalities to highlight mechanisms.

Differences in Infant Care Practices and Smoking among Hispanic Mothers Living in the United States

OBJECTIVE

To assess the association between maternal birth country and adherence to the American Academy of Pediatrics safe sleep recommendations in a national sample of Hispanic mothers, given that data assessing the heterogeneity of infant care practices among Hispanics are lacking.

STUDY DESIGN

We used a stratified, 2-stage, clustered design to obtain a nationally representative sample of mothers from 32 US intrapartum hospitals. A total of 907 completed follow-up surveys (administered 2-6 months postpartum) were received from mothers who self-identified as Hispanic/Latina, forming our sample, which we divided into 4 subpopulations by birth country (US, Mexico, Central/South America, and Caribbean). Prevalence estimates and aORs were determined for infant sleep position, location, breastfeeding, and maternal smoking.

RESULTS

When compared with US-born mothers, we found that mothers born in the Caribbean (aOR 4.56) and Central/South America (aOR 2.68) were significantly more likely to room share without bed sharing. Caribbean-born mothers were significantly less likely to place infants to sleep supine (aOR 0.41). Mothers born in Mexico (aOR 1.67) and Central/South America (aOR 2.57) were significantly more likely to exclusively breastfeed; Caribbean-born mothers (aOR 0.13) were significantly less likely to do so. Foreign-born mothers were significantly less likely to smoke before and during pregnancy.

CONCLUSIONS

Among US Hispanics, adherence to American Academy of Pediatrics safe sleep recommendations varies widely by maternal birth country. These data illustrate the importance of examining behavioral heterogeneity among ethnic groups and have potential relevance for developing targeted interventions for safe infant sleep.

Urban Young Adults’ Adaptive Functioning

Research on the association between prenatal substance exposures and adaptive functioning among young adults is limited, with inconsistent conclusions. In a prospective longitudinal study of 138 urban young adults, prenatal substance exposures were identified at birth from maternal self-report, urine screens, and/or infant meconium. At follow-up between ages 18 and 24 years, masked interviewers assessed level of adaptive functioning, a composite indicator comprising five domains: education, housing, adolescent pregnancy, arrest history, and employment. A significant negative association was found between prenatal tobacco exposure and adaptive functioning, particularly among females with heavier exposure. This association with heavier, but not lighter, prenatal tobacco exposure is consistent with a neuroteratologic explanation, but other, non-biological explanations cannot be ruled out. No statistically significant associations were observed between prenatal cocaine, marijuana, or low-moderate alcohol exposure and young adult adaptive functioning.
