Therapeutic plasma exchange in paediatric nephrology in Ireland.

BACKGROUND: Therapeutic plasma exchange (TPE) is utilised in the management of a limited number of paediatric renal conditions. Despite its widespread acceptance and advancements in the practice of apheresis, there remains a paucity of data pertaining to paediatrics. We present a large retrospective review of our cohort of paediatric patients undergoing TPE for renal indications, outlining their outcomes and complications. METHODS: A retrospective chart review was conducted for all patients (under 16 years) undergoing TPE for renal conditions between January 2002 and June 2019 in Ireland. Demographic and clinical data were extracted, with patients anonymised and stratified according to their pathology. RESULTS: A total of 58 patients were identified. A total of 1137 exchanges were performed using heparin sodium anticoagulation. The median age was 35.5 months (IQR 18-110 months). The leading indication was neurological involvement in Shiga toxin-producing Escherichia coli haemolytic uraemic syndrome (STEC-HUS) (n = 29). Complications (minor or major) occurred in 65.5% (n = 38) of patients, with most experiencing minor complications 58.6% (n = 34). Asymptomatic hypocalcaemia was the most common complication in 43.1% (n = 25). CONCLUSIONS: Our experience of TPE, spanning 1137 exchanges, proved a safe, well-tolerated therapy. Most complications were minor, and with therapy conducted in specialised centres, there are very low levels of adverse events.

Transitional care models in adolescent kidney transplant recipients-a systematic review.

BACKGROUND: Adolescence is a time of significant change for patients, guardians and clinicians. The paediatrician must ensure patients develop the necessary skills and knowledge required to transition and to function as an independent entity, with autonomy over their own care. The transfer from paediatric to adult care carries an increased risk of graft-related complications attributable to a multitude of reasons, particularly non-adherence to immunosuppressive medicines and poor attendance at scheduled appointments. This systematic review was conducted to ascertain the transitional care models available to clinicians caring for kidney transplant recipients and to compare the approach in each respective case. METHODS: A systematic review was performed, in a methodology outlined by the PRISMA guidelines. OVID MEDLINE and EMBASE databases were searched for studies that outlined valid, replicable models pertaining to transitional care of paediatric kidney transplant recipients between 1946 and Quarter 3 of 2021. The reference lists of selected articles were also perused for further eligible studies and experts in the field were consulted for further eligible articles. Two investigators assessed all studies for eligibility and independently performed data extraction. Any discrepancies were settled by consensus. RESULTS: A total of 1121 abstracts were identified, which was reduced to 1029 upon removal of duplicates. A total of 51 articles were deemed appropriate for full-text review and critical appraisal. A total of 12 articles that described models for transition pertaining to kidney transplant patients were included in qualitative synthesis. Every paper utilized a different transition model. All but one model included a physician and nurse at minimum in the transition process. The involvement of adult nephrologists, medical social work, psychology and psychiatry was variable. The mean age for the initiation of transition was 13.4 years (range: 10-17.5 years). The mean age at transfer to adult services was 18.3 years (range: 16-20.5 years). CONCLUSIONS: Despite the well-established need for good transitional care for paediatric solid-organ transplant recipients, models tailored specifically for kidney transplant recipients are lacking. Further research and validation studies are required to ascertain the best method of providing effective transitional care to these patients. Transitional care should become a standardized process for adolescents and young adults with kidney transplants.

Neurological involvement in children with hemolytic uremic syndrome.

Our objective was to establish the rate of neurological involvement in Shiga toxin-producing Escherichia coli-hemolytic uremic syndrome (STEC-HUS) and describe the clinical presentation, management and outcome. A retrospective chart review of children aged ≤ 16 years with STEC-HUS in Children's Health Ireland from 2005 to 2018 was conducted. Laboratory confirmation of STEC infection was required for inclusion. Neurological involvement was defined as encephalopathy, focal neurological deficit, and/or seizure activity. Data on clinical presentation, management, and outcome were collected. We identified 240 children with HUS; 202 had confirmed STEC infection. Neurological involvement occurred in 22 (11%). The most common presentation was seizures (73%). In the neurological group, 19 (86%) were treated with plasma exchange and/or eculizumab. Of the 21 surviving children with neurological involvement, 19 (91%) achieved a complete neurological recovery. A higher proportion of children in the neurological group had renal sequelae (27% vs. 12%, P = .031). One patient died from multi-organ failure.Conclusion: We have identified the rate of neurological involvement in a large cohort of children with STEC-HUS as 11%. Neurological involvement in STEC-HUS is associated with good long-term outcome (complete neurological recovery in 91%) and a low case-fatality rate (4.5%) in our cohort. What is Known: • HUS is associated with neurological involvement in up to 30% of cases. • Neurological involvement has been reported as predictor of poor outcome, with associated increased morbidity and mortality. What is New: • The incidence of neurological involvement in STEC-HUS is 11%. • Neurological involvement is associated with predominantly good long-term outcome (90%) and a reduced case-fatality rate (4.5%) compared to older reports.

Temporal trends in smoking and nicotine dependence in relation to co-occurring substance use in the United States, 2005-2016.

BACKGROUND: Despite an overall decline in tobacco use in the United States, secular trends of smoking and nicotine dependence with co-occurring substance use are not well characterized. METHODS: We examined self-reported tobacco and other substance use in 22,245 participants age 21-59 in the United States from six waves of the National Health and Nutrition Examination Survey (NHANES). Using Joinpoint regression, we assessed secular trends of smoking and nicotine dependence as a function of co-occurring use of alcohol, prescription opioids, marijuana/hashish, cocaine/heroin/methamphetamine, or other injection drug use. Multivariable logistic regressions were fitted to identify the potential risk factors. RESULTS: During 2005-2016, the prevalence of current smoking decreased (without co-occurring substance use: 17.0 %-12.7 %; with co-occurring use of one substance: 35.3 % to 24.6 %; with co-occurring use of two or more substances: 53.8 %-42.2 %), and moderate-to-severe nicotine dependence decreased as well (8.0 %-4.2 %, 16.0 %-8.8 %, and 23.9 %-15.7 %, respectively). Smoking and nicotine dependence were more likely in those with co-occurring use of one substance (current smoking: odds ratio [OR] = 2.22, 95 % confidence interval [CI] = 2.01-2.45); nicotine dependence: OR = 1.88, 95 % CI = 1.63-2.17) and in those with co-occurring use of two or more substances (current smoking: OR = 5.25, 95 % CI = 4.63-5.95; nicotine dependence: OR = 3.24, 95 % CI = 2.72-3.87). CONCLUSIONS: Co-occurring substance use was associated with smaller reductions in tobacco use, over time, and with increased odds of nicotine dependence. This suggests that co-occurring substance users should be regarded as a tobacco-related disparity group and prioritized for tobacco control interventions.

Timing of mortality in mothers with recurrent convictions for driving under the influence of alcohol and their children, from childbirth to child age 17.

BACKGROUND: We tested variation in the timing of child and maternal mortality associated with severe maternal AUD, as represented by recurrent arrests for driving under the influence of alcohol (rDUI). METHODS: rDUI mothers (N = 1614) and Controls with no alcohol-related driving offenses (N = 109,928) who gave birth in Missouri from 2000 to 2004 were identified using vital records. Propensity score matching adjusted for birth record measures including delayed prenatal care, smoking during pregnancy, relationship with reproductive partner [married/unmarried, paternity acknowledged/unacknowledged], partner DUI status from driving records, and for socioeconomic characteristics of maternal residential census tract at birth derived from census data. Survival analysis was used to test months from childbirth to child or maternal death as a function of lifetime rDUI status. RESULTS: Maternal rDUIs were associated with a consistently elevated probability of child mortality from birth through child age 17 after propensity score-adjustment (Hazard Ratio [HR] = 1.70, 95 % CI = 1.17-2.47). Maternal mortality was not elevated, relative to Controls, until child age 6-11 (HR = 1.58, 95 % CI = 1.05-2.35) and increased again from child age 12-17 (HR = 4.12, 95 % CI = 3.04-5.86). CONCLUSIONS: Severe maternal AUD, as characterized by rDUI, increases the risk for child mortality over that of Controls through age 17. Delays in rDUI maternal mortality until child age 6 may indicate a period when maternal referral for intervention to reduce harm to child and mother is likely to be especially effective.

Long-term outcome of transplant ureterostomy in children: A National Review.

BACKGROUND: CAKUT are the most common cause of end-stage renal failure in children (Pediatr Nephrol. 24, 2009, 1719). Many children with CAKUT have poor urinary drainage which can compromise post-transplant outcome. Identifying safe ways to manage anatomical abnormalities and provide effective urinary drainage is key to transplant success. Much debate exists regarding optimum urinary diversion techniques. The definitive formation of a continent urinary diversion is always preferable but may not always be possible. We explore the role of ureterostomy formation at transplantation in a complex pediatric group. METHODS: We report six pediatric patients who had ureterostomy formation at the time of transplantation at the National Paediatric Transplant Centre in Dublin, Ireland. We compared renal function and burden of urinary tract infection to a group with alternative urinary diversion procedures and a group with normal bladders over a 5-year period. RESULTS: There was no demonstrable difference in estimated glomerular filtration rate between the groups at 5-year follow-up. The overall burden of UTI was low and similar in frequency between the three groups. CONCLUSIONS: Ureterostomy formation is a safe and effective option for temporary urinary diversion in children with complex abdominal anatomy facilitating transplantation; it is, however, important to consider the implications and risk of ureterostomy for definitive surgery after transplantation.

Marital status, partner acknowledgment of paternity, and neighborhood influences on smoking during first pregnancy: findings across race/ethnicity in linked administrative and census data.

BACKGROUND: Improving prediction of cigarette smoking during pregnancy (SDP), including differences by race/ethnicity and geography, is necessary for interventions to achieve greater and more equitable SDP reductions. METHODS: Using individual-level data on singleton first births, 2010-2017 (N = 182,894), in a US state with high SDP rates, we predicted SDP risk as a function of reproductive partner relationship (marital status, paternity acknowledgement), maternal and residential census tract sociodemographics, and census tract five-year SDP rate. RESULTS: SDP prevalence was 12.7% (white non-Hispanics, WNH), 6.8% (Black/African Americans, AA), 19.5% (Native American, NA), 4.7% (Hispanic, H), and 2.8% (Asian, AS). In WNH and AA, with similar trends in other groups, after adjustment for non-linear effects of maternal age and education and for census tract risk-factors, there was a consistent risk-ordering of SDP rates by reproductive partner relationship: married/with paternity acknowledged < unmarried/acknowledged < unmarried/unacknowledged < married/unacknowledged. Associations with census tract SDP rate, adjusted for maternal and census tract sociodemographics, were stronger for AA and H (OR 2.65-2.67) than for NA (OR = 1.91), WNH (OR = 1.75), or AS (NS). AA SDP was increased in tracts having a higher proportion of WNH residents and was reduced in comparison with WNH at every combination of age, education and partner relationship. CONCLUSIONS: Inattention to differences by race/ethnicity may obscure SDP risk factors. Despite marked race/ethnic differences in unmarried-partner cohabitation rates, failure to acknowledge paternity emerged as an important and consistent risk-predictor. Census-tract five-year SDP rates have heterogeneous origins, but the association of AA SDP risk with increased racial heterogeneity suggests an important influence of neighbor risk behaviors.

Alcohol Dependence and Reproductive Onset in Women, Updated: Analyses of Research and State-Level Administrative Data.

OBJECTIVE: The present study updates prior research, incorporating state-level administrative data to examine associations between self-reported history of alcohol dependence and birth record-derived reproductive onset, the latter assessed through peak childbearing years. METHOD: Participants included 542 African ancestry (AA) and 2,928 European or other ancestry (EA) female twins ascertained through Missouri birth records and recruited as part of a birth cohort study of like-sex female pairs born between 1975 and 1985. Analyses were limited to twins for whom residence in Missouri when of reproductive age could be documented, including twins who left Missouri but later returned. Cox proportional hazards regression models were estimated predicting age at first childbirth from history of alcohol dependence, separately for AA and EA twins, without and with adjustment for sociodemographic characteristics, comorbid psychopathology and other substance involvement, overweight/obesity status, and family-of-origin and childhood risk factors. RESULTS: Among EA twins, alcohol dependence predicted both early and delayed childbearing; in adjusted models, alcohol dependence was associated with overall delayed childbearing. Associations between alcohol dependence and reproductive onset were nonsignificant among AA twins. CONCLUSIONS: Findings for EA twins are consistent with the broader literature indicating increased risk of teen motherhood associated with early-onset and problem drinking, but suggest that this may be explained by other correlated risk factors. The more robust finding, confirming relatively recent research, is of delayed childbearing associated with alcohol dependence.

Sexual Risk Behaviors during Adolescence: Associations with Childhood and Adolescent BMI.

Research examining associations between unhealthy weight and sexual risk behaviors derives primarily from cross-sectional studies conducted at varying ages during adolescence. The present study examined longitudinal associations between adolescent sexual risk behaviors and Body Mass Index (BMI), the latter measured prospectively from childhood through adolescence. Data were drawn from an 8095 individuals between the ages of 14 and 19 at last assessment, including 1768 Hispanic (52% female), 2659 non-Hispanic Black (Black; 50% female), and 3668 non-Hispanic, non-Black (predominantly White; 49% female). Childhood BMI predicted increased sexual risk-taking during adolescence for Black and White youth, and increases in BMI predicted increased sexual risk-taking for White females and Black males. The findings highlight differential patterns of association between BMI and sexual risk behaviors for Hispanic, Black, and White females and males with implications for prevention discussed.

The interaction of sociodemographic risk factors and measures of nicotine dependence in predicting maternal smoking during pregnancy.

BACKGROUND: Understanding differences in nicotine dependence assessments' ability to predict smoking cessation is complicated by variation in quit attempt contexts. Pregnancy reduces this variation, as each pregnant smoker receives the same strong cessation incentive. Cigarette smoking during pregnancy (SDP) provides a powerful paradigm for analyzing the interplay between nicotine dependence measures and sociodemographics in predicting cessation failure. METHODS: Data from a female twin cohort (median birth year 1980), assessed in teens and early twenties, were merged with birth records to identify those with smoking history who experienced childbirth (N = 1657 births, N = 763 mothers). Logistic regression predicting SDP, as a function of birth record sociodemographic variables, generated a sociodemographic risk-score. Further analysis incorporated the risk-score with data from research interviews on DSM-IV-Nicotine Dependence symptom count, Heaviness of Smoking Index. RESULTS: Low maternal educational level, younger age at childbirth, and being unmarried all contributed risk for SDP. In addition to sociodemographic risk-score, the best predictors of SDP included HSI-score (OR:1.51), their two-way interaction (OR:0.39; reduced impact of dependence at intermediate-high sociodemographic risk), history of ≥ two failed quit attempts (OR:1.38), and a dummy variable for prior pregnancy at time of assessment (OR:1.82). DSM-IV-Nicotine Dependence symptoms underperformed the Heaviness of Smoking Index and did not improve prediction when added to the best model. CONCLUSIONS: The 2-item Heaviness of Smoking Index measure and report of ≥ two failed quit attempts performed best for predicting SDP. The contribution of either nicotine dependence measure to SDP risk was diminished at increased levels of sociodemographic risk.

Parental relationship dissolution and child development: the role of child sleep quality.

We utilized the Fragile Families and Child Wellbeing longitudinal dataset to evaluate associations among a maternal relationship dissolution, childhood sleep, and child development, specifically externalizing and internalizing symptoms, attention and social difficulties, as well as cognitive ability, when children were ages 5 (n = 3590) and 9 (n = 3062). A maternal relationship dissolution was related to poorer child sleep quality at ages 5 and 9. There was evidence of an indirect relation from a maternal relationship dissolution to child development through poor sleep quality when the child was 5 and 9 years old. The implications of this work are discussed.

Associations between Childhood Weight Status and Timing of First Sex in an Ethnically Diverse Sample.

BACKGROUND: Most research linking weight status and timing of first sexual intercourse is cross-sectional in design, with few longitudinal analyses published to date. We examined associations between childhood weight status and subsequent onset of first sexual intercourse within a survival analytic framework, testing for differences among Hispanic, black, and white females and males. METHODS: Data were drawn from 6379 child respondents of the 1979 National Longitudinal Survey of Youth aged 13 and older at last assessment. Cox proportional hazards regression models were estimated predicting age at first sexual intercourse from weight status during childhood without and with adjustment for correlated risk factors. Analyses were conducted separately by sex and race/ethnicity, with interactions among weight status, respondent sex, and race/ethnicity modeled in subsidiary analyses. RESULTS: Overweight status predicted earlier sexual intercourse among Hispanic females, whereas obese status predicted delayed sexual intercourse among white males, both relative to peers of the same race/ethnicity with healthy weight. Underweight status predicted delayed sexual intercourse among Hispanic males relative to peers with healthy weight. Significant differences by sex and race/ethnicity were observed in tests of interactions. CONCLUSIONS: Findings document associations between childhood weight status and subsequent onset of first sexual intercourse, especially among Hispanic females and males and white males. Together, results highlight respondent sex and race/ethnicity as potential moderators and also unique risk for Hispanic females who were overweight as children, and who may benefit from early screening and education to delay sexual initiation to reduce risk of early unplanned pregnancy and sexually transmitted infections.

The Impact of Traumatic Experiences on Risky Sexual Behaviors in Black and White Young Adult Women.

BACKGROUND: Trauma exposure has been linked to risky sexual behavior (RSB), but few studies have examined the impact of distinct trauma types on RSB in one model or how the association with trauma and RSB may differ across race. PURPOSE: The objective of the current study was to examine the contribution of trauma exposure types to RSB-substance-related RSB and partner-related RSB identified through factor analysis-in young Black and White adult women. METHODS: We investigated the associations of multiple trauma types and RSB factor scores in participants from a general population sample of young adult female twins (n = 2,948). We examined the independent relationship between specific traumas and RSB, adjusting for substance use, psychopathology, and familial covariates. All pertinent constructs were coded positive only if they occurred before sexual debut. RESULTS: In Black women, sexual abuse was significantly associated with substance-related and partner-related RSB, but retained significance only for partner-related RSB in a fully adjusted model. For White women, sexual abuse and physical abuse were associated with both RSB factors in the base and fully adjusted models. Witnessing injury or death was only associated with RSBs in base models. For both groups, initiating alcohol (for Black women), alcohol, or cannabis (for White women) before sexual debut (i.e., early exposure) was associated with the greatest increased odds of RSB. CONCLUSIONS: Data highlight the contribution of prior sexual abuse to RSBs for both White and Black women, and of prior physical abuse to RSBs for White women. Findings have implications for intervention after physical and sexual abuse exposure to prevent RSB, and thus, potentially reduce sexually transmitted infection/human immunodeficiency virus infection and unintended pregnancy in young women.

Clinical Relapses of Atypical HUS on Eculizumab: Clinical Gap for Monitoring and Individualised Therapy.

Atypical hemolytic uremic syndrome (aHUS) is caused by dysregulation of the complement system. A humanised anti-C5 monoclonal antibody (eculizumab) is available for the treatment of aHUS. We present the first description of atypical HUS in a child with a coexistent diagnosis of a POL-III leukodystrophy. On standard eculizumab dosing regime, there was evidence of ongoing C5 cleavage and clinical relapses when immunologically challenged. Eculizumab is an effective therapy for aHUS, but the recommended doses may not be adequate for all patients, highlighting the need for ongoing efforts to develop a strategy for monitoring of treatment efficacy and potential individualisation of therapy.

Interactive Effects of Maternal Alcohol Problems and Parental Separation on Timing of Daughter's First Drink.

BACKGROUND: Few studies examine risk to offspring who experience both parental alcohol problems and parental separation and still fewer consider gender of the affected parent. We examined interactive effects of maternal versus paternal alcohol problems and parental separation on timing of first alcoholic drink in daughters. METHODS: Data were drawn from a sample of 3,539 European (or other) ancestry (EA) and 611 African ancestry (AA) female twins born between 1975 and 1985, median age 15 at first assessment. Cox proportional hazards regression models were estimated predicting age at first full drink from parental history of alcohol problems (mother only, father only, or both parents), parental separation during childhood, and the interaction of parental alcohol problems and parental separation. Cox models were estimated without and with adjustment for correlated risk factors, separately for EA and AA twins. RESULTS: For both EA and AA twins, a significant interaction between parental separation and mother-only alcohol problems was observed, suggesting reduced risk of drinking associated with mother-only alcohol problems in separated versus intact families. CONCLUSIONS: Findings highlight parental separation as an important moderator of risk to children of mothers who have a history of problem drinking, with interactive effects observed consistently across racial group. To identify underlying processes, additional research is needed with more detailed characterization of separated families where mother only has a history of alcohol problems.

Single Motherhood, Alcohol Dependence, and Smoking During Pregnancy: A Propensity Score Analysis.

OBJECTIVE: Few studies linking single motherhood and maternal smoking during pregnancy consider correlated risk from problem substance use beyond history of smoking and concurrent use of alcohol. In the present study, we used propensity score methods to examine whether the risk of smoking during pregnancy associated with single motherhood is the result of potential confounders, including alcohol dependence. METHOD: Data were drawn from mothers participating in a birth cohort study of their female like-sex twin offspring (n = 257 African ancestry; n = 1,711 European or other ancestry). We conducted standard logistic regression models predicting smoking during pregnancy from single motherhood at twins' birth, followed by propensity score analyses comparing single-mother and two-parent families stratified by predicted probability of single motherhood. RESULTS: In standard models, single motherhood predicted increased risk of smoking during pregnancy in European ancestry but not African ancestry families. In propensity score analyses, rates of smoking during pregnancy were elevated in single-mother relative to two-parent European ancestry families across much of the spectrum a priori risk of single motherhood. Among African ancestry families, within-strata comparisons of smoking during pregnancy by single-mother status were nonsignificant. CONCLUSIONS: These findings highlight single motherhood as a unique risk factor for smoking during pregnancy in European ancestry mothers, over and above alcohol dependence. Additional research is needed to identify risks, beyond single motherhood, associated with smoking during pregnancy in African ancestry mothers.

Timing of First Alcohol Use and First Sex in Male and Female Adolescents.

PURPOSE: We examined associations between timing of first alcohol use and first sexual intercourse in adolescent males and potential differences in observed associations between males and females. METHODS: Data were drawn from 4,079 male and 4,059 female participants of the National Longitudinal Study of Youth 1997, aged 12-16 years at the first assessment. Cox proportional hazards regression models were estimated predicting age at first sexual intercourse from age at first alcohol use, without and with adjustment for correlated sociodemographic and individual- and family-level risk factors. Analyses were conducted separately for males and females, with interactions between alcohol use and respondent sex (female vs. male) modeled in subsidiary analyses. RESULTS: Onset of first drink was strongly predictive of earlier sexual intercourse for both males and females, with effects of drinking most pronounced for females during early adolescence. CONCLUSIONS: Results highlight age at first alcohol use as an important predictor of sexual onset in male as well as female adolescents and suggest that effective prevention efforts focusing on delay of sexual intercourse might also focus on delay on alcohol use.

The Influence of Paternal Separation, Paternal History of Alcohol Use Disorder Risk, and Early Substance Use on Offspring Educational Attainment by Young Adulthood.

OBJECTIVE: This study aimed to determine the associations among paternal alcohol problems, separation, and educational attainment in European American and African American offspring and whether offspring early alcohol/tobacco/marijuana use influenced these associations. METHOD: Families with offspring ages 13-19 years at intake were selected from state birth records and screened by telephone to determine high-risk or low-risk status (with/without paternal heavy drinking). Families of men with two or more driving-under-the-influence offenses were added as a very-high-risk group. Data from 340 African American and 288 European American offspring who were not enrolled in school at their last interview were analyzed. Educational attainment was modeled as less than high school, high school only (reference category), and some college or higher. Separation was defined as offspring report of not having lived continuously in the same household with their biological father from birth to age 14. Analyses were stratified by race. RESULTS: In European Americans, neither family risk status nor early alcohol/tobacco/marijuana use was associated with educational outcomes. However, paternal separation significantly elevated the likelihood of not completing high school in all models (relative risk ratios [RRRs] = 6.0-8.1, p <.001). For African American offspring, likelihoods of high school noncompletion were elevated marginally for paternal separation in only one model, but significantly for early marijuana use (RRRs = 2.8-3.2, p < .05). Very-high-risk status significantly reduced the likelihood of post-high school education in an adjusted model (RRR = 0.4, p < .05). CONCLUSIONS: High school noncompletion was significantly associated with paternal separation in European Americans and with early marijuana use in African American offspring. In addition, very-high-risk status reduced the likelihood of post-high school education in African American offspring only, suggesting that research with ethnically diverse samples yields important differences when examining outcomes of both separation and substance use on offspring education.

Childhood family characteristics and prescription drug misuse in a national sample of Latino adults.

Prescription drug misuse is a growing public health concern and has been understudied in Latino populations. The current study tests the relationships between childhood and family characteristics and prescriptions drug misuse among adult Latinos. A subsample of 8,308 Latinos from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) were examined. Logistic regression analyses tested associations between parental alcoholism, parental divorce before age 18, and parental death before age 18 and prescription drug misuse and prescription drug use disorder. Parental alcoholism and parental divorce increased the odds of both prescription drug misuse and use disorder. Parental death increased the odds of prescription drug use disorders. The results have important implications for understanding the complex associations between family psychosocial history and prescription drug misuse. (PsycINFO Database Record
