Sleep Characteristics and Behavioral Problems Among Children of Alcoholics and Controls.

Past research has indicated that both sleep difficulties and a parental history of alcoholism increase the risk of behavioral problems. But it is not known whether sleep difficulties differentially increase the risk of problem behaviors among children of alcoholics (COAs) and controls. We compared multiple measures of sleep and the relationships between sleep and behavioral problems in these 2 groups of children. One hundred and fifteen children aged 8 to 12 (67% COAs; 56% girls; Mage =10.85, SDage =1.51) participated in this study. Data presented here were taken from Time 1 of a larger prospective study designed to understand the relationship between sleep and alcohol use. All participants were naïve to alcohol and other illicit drugs. Participants were asked to wear an actigraph watch on their nondominant wrist for 1week. Parents completed the Pediatric Sleep Questionnaire and the Achenbach Child Behavior Checklist. Parents of COAs were more likely to rate their children as overtired compared with parents of non-COAs. Structural equation modeling analyses focusing on overall internalizing and externalizing problems did not reveal any group differences on the relationships between sleep measures and behavioral problems. Regression analyses focusing on specific behavioral problems showed that longer total sleep time, parental ratings of "sleep more" and "sleep less" than other children interacted with COA status to predict specific behavioral problems. Sleep difficulties and duration appear to be a general risk factor for behavioral problems in both COAs and non-COAs, yet the relationships between specific sleep parameters and behavioral problems appear to be different between the 2 groups.

Modeling Trajectories of Adolescent-Perceived Family Conflict: Effects of Marital Dissatisfaction and Parental Alcoholism.

We evaluated the effects of marital dissatisfaction on adolescent-perceived conflict in 435 families with and without a parental history of alcoholism. On average, family conflict decreased linearly as adolescents aged. Families with an alcoholic parent demonstrated higher adolescent-reported family conflict and this effect was partially mediated by higher mother- and father-reported marital dissatisfaction. Families with higher marital dissatisfaction had greater conflict when adolescents were young (based on fathers' marital dissatisfaction) and as they aged (based on mother's marital dissatisfaction). Years in which mothers reported higher marital dissatisfaction than usual coincided with years in which adolescents reported greater family conflict. Results indicate that marital dissatisfaction has both within and between-family effects on adolescent perceptions of conflict.

Parental Separation, Parental Alcoholism, and Timing of First Sexual Intercourse

PurposeWe examined timing of first voluntary sexual intercourse as a joint function of parental separation during childhood and parental history of alcoholism. MethodsData were drawn from a birth cohort of female like-sex twins (n = 569 African ancestry [AA]; n = 3,415 European or other ancestry [EA]). Cox proportional hazards regression was conducted predicting age at first sex from dummy variables coding for parental separation and parental alcoholism. Propensity score analysis was also employed to compare intact and separated families, stratified by predicted probability of separation. ResultsEarlier sex was reported by EA twins from separated and alcoholic families, compared to EA twins from intact nonalcoholic families, with effects most pronounced through the age of 14 years. Among AA twins, effects of parental separation and parental alcoholism were largely nonsignificant. Results of propensity score analyses confirmed unique risks from parental separation in EA families, where consistent effects of parental separation were observed across predicted probability of separation. For AA families, there was poor matching on risk factors presumed to predate separation, which limited interpretability of survival-analytic findings. ConclusionsIn European American families, parental separation during childhood is an important predictor of early-onset sex, beyond parental alcoholism and other correlated risk factors. To characterize risk for African Americans associated with parental separation, additional research is needed where matching on confounders can be achieved.

Parental alcohol history differentially predicts offspring disorders in distinct subgroups in Israel.

The association between alcoholism in parents and related disorders in their offspring is well established in cultures with intermediate/high alcohol consumption, but not in those with low consumption, such as Israel. This study investigated differences in parental transmission of alcohol problems and related psychopathology between immigrants from the former Soviet Union (FSU) to Israel and other Israelis-two Israeli subgroups with differing alcohol consumption behaviors and social norms. A total of 1,347 adults from a household sample were interviewed. Regression analyses were used to examine associations between parental alcohol problems and participant disorders: alcohol, nicotine, and cannabis use disorders (AUD, NUD, CUD); antisocial personality disorder (ASPD); major depressive disorder (MDD); and posttraumatic stress disorder (PTSD). We also examined the associations of parental alcohol problems with participant disorders characterized with two latent factors: externalizing (EXT: AUD, NUD, CUD, ASPD) and internalizing (INT: MDD, PTSD). Differential parental transmission of alcohol problems in FSU (n = 315) and non-FSU (n = 1,032) Israelis was examined with statistical interaction. Among emigrants from the FSU, parental alcohol problems predicted AUD, NUD, CUD, ASPD, PTSD, EXT, and INT (mean ratios = 1.38-4.83). In non-FSU Israelis, parental alcohol problems predicted only ASPD and PTSD (mean ratios = 1.08-4.09). Significant interactions were observed for AUD, CUD, PTSD, and EXT; each relationship was stronger in FSU Israelis and null (AUD, CUD, EXT) or less robust (PTSD) in other Israelis. Parental alcohol problems were related to substance use and psychiatric disorders differently in FSU and other Israelis, two groups with different alcohol consumption levels and drinking norms. We propose that, in social contexts that vary in the degree to which they constrain alcohol behavior, underlying genetic predispositions may manifest as different disorders.

Childhood maltreatment, stressful life events, and alcohol craving in adult drinkers.

Little is known about the relationship between stressful life events and alcohol craving in the general population, and whether a history of childhood maltreatment sensitizes individuals to crave alcohol after adult stressors. Participants were 22,147 past-year drinkers from Wave 2 (2004 to 2005) of the National Epidemiologic Survey on Alcohol and Related Conditions. A structured, face-to-face interview assessed past-year stressful life events, alcohol craving, and history of childhood maltreatment. Logistic regression was used to generate adjusted odds ratios (aOR) to evaluate the relationship between stressful life events and craving, adjusting for demographic characteristics and parental history of alcoholism. Interaction between stressful life events and childhood maltreatment was also assessed. Compared to participants with no stressful life events, those with ≥ 3 events had increased odds of moderate alcohol craving (aOR = 3.15 [95% CI = 2.30 to 4.33]) and severe craving (aOR = 8.47 [95% CI = 4.78 to 15.01]). Stressful life events and childhood maltreatment interacted in predicting severe craving (p = 0.017); those with ≥ 3 events were at higher risk of craving if they had been exposed to childhood maltreatment. A direct relationship between stressful life events and risk of alcohol craving was observed. Further, history of childhood maltreatment increased the salience of stressful life events in adulthood. Future studies should examine the role of psychiatric comorbidity in more complex models of stress sensitization and alcohol craving.

Risks for early substance involvement associated with parental alcoholism and parental separation in an adolescent female cohort

BackgroundWe examined timing of substance involvement as a joint function of parental history of alcoholism and parental separation during childhood. MethodData were drawn from a large cohort of female like-sex twins [n=613 African Ancestry (AA), n=3550 European or other ancestry (EA)]. Cox proportional hazards regression was conducted predicting age at first use of alcohol, first alcohol intoxication, first use and regular use of cigarettes, and first use of cannabis and other illicit drugs from dummy variables coding for parental alcoholism and parental separation. Propensity score analysis was also conducted comparing intact and separated families by predicted probability of parental separation. ResultsIn EA families, increased risk of substance involvement was found in both alcoholic and separated families, particularly through ages 10 or 14 years, with risk to offspring from alcoholic separated families further increased. In AA families, associations with parental alcoholism and parental separation were weak and with few exceptions statistically nonsignificant. While propensity score findings confirmed unique risks observed in EA families, intact and separated AA families were poorly matched on risk-factors presumed to predate parental separation, especially parental alcoholism, requiring cautious interpretation of AA survival-analytic findings. ConclusionFor offspring of European ancestry, parental separation predicts early substance involvement that is not explained by parental alcoholism nor associated family background characteristics. Additional research is needed to better characterize risks associated with parental separation in African American families.

Self and partner alcohol-related problems among ACOAs and non-ACOAs: Associations with depressive symptoms and motivations for alcohol use

The present study examined whether drinking motivations and depressive symptoms would have a stronger impact on alcohol-related problems among adult children of alcoholics (ACOAs) and their dating partners as compared to non-ACOAs and their dating partners. Participants were 197 undergraduate (60 ACOAs, 137 non-ACOAs) 18 to 25year-old female drinkers in dating relationships. Participants completed measures of ACOA screening, depressive symptoms, and drinking motives, as well as alcohol-related problems for themselves and their partner. Although no differences were found between ACOA and non-ACOA women's alcohol-related problems, ACOA women and women with greater depressive symptoms were at a higher risk of having a partner with more alcohol-related problems. In addition, we found that regardless of parental history of alcoholism, higher depressive symptoms coupled with stronger motives for drinking to cope with stressors predicted participants' own alcohol-related problems. These findings demonstrate the need for future research to examine additional factors that may moderate the effects of depressive symptoms and ACOA status on female college student drinking problems. A greater understanding of the unique and interactive effects of these variables on alcohol-related problems in both young women and their dating partners can aid in the development of prevention programs more targeted to the specific vulnerabilities of this population.

Dissipation of sleep pressure is stable across adolescence

The sleep electroencephalogram (EEG) undergoes many changes during adolescence. We assessed whether sleep homeostasis is altered across adolescent development using two measures: the dissipation of slow-wave activity (SWA, 0.6–4.6Hz) across the night and the rate of build-up of SWA in the first non-rapid eye movement (NREM) sleep episode. Furthermore, we examined the association between homeostatic and circadian measures, by correlating the build-up of SWA in the first non-rapid eye movement (NREM) sleep episode with circadian phase. Finally, we compared the dissipation of SWA in individuals with (PH+) and without (PH−) a parental history of alcohol abuse/dependence. Twenty children (8 PH+) and 25 teens (10 PH+) underwent two consecutive polysomnographic recordings at ages 9/10 and 15/16years and again 1.5–3years later. Thirteen young adults (ages 20–23 years; no PH+) were assessed one time. The decay of Process S was modeled for each individual at each assessment using data from both recordings. Four parameters of Process S were derived for EEG derivation C3/A2: time constant of the decay, lower asymptote (LA), the level of S at sleep onset (SSO), and SSO minus LA. We found no change in these parameters between assessments for the children and teen cohorts. Between-subject analysis of the follow-up assessment for children (ages 11–13 years) and the initial assessment for teens (ages 15/16 years) showed no difference in these parameters, nor did follow-up assessment of teens (ages 17–19 years) compared to the single assessment of young adults (ages 20–23 years). Similarly, we observed no developmental changes in the rate of the build-up of SWA in the first NREM sleep episode for our within- and between-subject analyses, or a correlation between this measure and circadian phase for either cohort. With regard to parental alcohol history, we found no difference in the dissipation of sleep pressure between PH+ and PH− children and teens. These results indicate that the dissipation of sleep pressure does not change across adolescent development, is not correlated with circadian phase, and does not differ between PH+ and PH− children and teens.

Adolescence and Parental History of Alcoholism: Insights from the Sleep EEG

Disrupted sleep is a common complaint of individuals with alcohol use disorder and in abstinent alcoholics. Furthermore, among recovering alcoholics, poor sleep predicts relapse to drinking. Whether disrupted sleep in these populations results from prolonged alcohol use or precedes the onset of drinking is not known. The aim of this study was to examine the sleep electroencephalogram (EEG) in alcohol-naïve, parental history positive (PH+), and negative (PH-) boys and girls. All-night sleep EEG recordings in 2 longitudinal cohorts (child and teen) followed at 1.5 to 3 year intervals were analyzed. The child and teen participants were 9/10 and 15/16 years old at the initial assessment, respectively. Parental history status was classified by Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria applied to structured interviews (DIS-IV) resulting in 14 PH- and 10 PH+ children and 14 PH- and 10 PH+ teens. Sleep data were visually scored in 30-second epochs using standard criteria. Power spectra were calculated for EEG derivations C3/A2, C4/A1, O2/A1, O1/A2 for nonrapid eye movement (NREM) and rapid eye movement (REM) sleep. We found no difference between PH+ and PH- individuals in either cohort for any visually scored sleep stage variable. Spectral power declined in both cohorts across assessments for NREM and REM sleep in all derivations and across frequencies independent of parental history status. With regard to parental history, NREM sleep EEG power was lower for the delta band in PH+ teens at both assessments for the central derivations. Furthermore, power in the sigma band for the right occipital derivation in both NREM and REM sleep was lower in PH+ children only at the initial assessment. We found no gross signs of sleep disruption as a function of parental history. Modest differences in spectral EEG power between PH+ and PH- children and teens indicate that a marker of parental alcohol history may be detectable in teens at risk for problem drinking.

Prospective investigation of psychological and affective pathways from childhood trauma to psychosis-like experiences in a UK birth cohort

with childhood maltreatment and sex on the risk for alcohol dependence. Using national data with extensive measures, we address these issues: (1) Do childhood sexual abuse, physical abuse, emotional abuse, physical neglect, and emotional neglect predict adult lifetime DSM-IV alcohol dependence, controlling for co-occurring maltreatments and other childhood traumas? (2) Are these relationships synergistically modified by parental alcoholism history? Method: Face-to-face interviews of 27 712 adult participants in the National Epidemiological Survey on Alcohol and Related Conditions were conducted. Results: Childhood physical, emotional, and sexual abuse, and physical neglect were associated with alcohol dependence (P b .001), controlling for demographics, co-occurring maltreatments, and other childhood trauma. A significant (P b .05) synergistic relationship between parental history and physical abuse was found in the entire sample (AP, 0.21), and between parental history and sexual abuse (AP, 0.31) and emotional neglect (AP, 0.26) in women. In other words, the risk of alcohol dependence given both parental history and the maltreatment was higher than what would be expected given the additive effect of each alone. Conclusions: Childhood maltreatments independently increased the risk of alcohol dependence, underscoring the importance of early identification and prevention and suggesting the need to develop and incorporate alcohol preventative components, such as cognitive restructuring, in maltreatment interventions. Importantly, the effect of physical abuse on alcohol dependence may depend on genetic vulnerability as suggested by the effect of parental history of alcoholism, whereas the effects of sexual abuse and emotional neglect may depend on this vulnerability among women. Thus, maltreatment may have a long-term negative impact, which may depend on genetic vulnerability and sex. Findings can be used to guide genetic studies and intervention development.

The Contribution of Parental Alcohol Use Disorders and Other Psychiatric Illness to the Risk of Alcohol Use Disorders in the Offspring

Few population-based studies have investigated associations between parental history of alcoholism and the risk of alcoholism in offspring. The aim was to investigate in a large cohort the risk of alcohol use disorders (AUD) in the offspring of parents with or without AUD and with or without hospitalization for other psychiatric disorder (OPD). Longitudinal birth cohort study included 7,177 men and women born in Copenhagen between October 1959 and December 1961. Cases of AUD were identified in 3 Danish health registers and cases of OPD in the Danish Psychiatric Central Register. Offspring registration with AUD was analyzed in relation to parental registration with AUD and OPD. Covariates were offspring gender and parental social status. Both maternal and paternal registration with AUD significantly predicted offspring risk of AUD (odds ratios 1.96; 95% CI 1.42 to 2.71 and 1.99; 95% CI 1.54 to 2.68, respectively). The association between maternal, but not paternal, OPD and offspring AUD was also significant (odds ratios 1.46; 95% CI 1.15 to 1.86 and 1.26; 95% CI 0.95 to 1.66, respectively). Other predictors were male gender and parental social status. A significant interaction was observed between paternal AUD and offspring gender on offspring AUD, and stratified analyses showed particularly strong associations of both paternal and maternal AUD with offspring AUD in female cohort members. Parental AUD was associated with an increased risk of offspring AUD independent of other significant predictors, such as gender, parental social status, and parental psychiatric hospitalization with other diagnoses. Furthermore, this association appeared to be stronger among female than male offspring. The results suggest that inherited factors related to alcoholism are at least as important in determining the risk of alcoholism among daughters as among sons.

Effects of a Diagnosis or Family History of Alcoholism on the Taste Intensity and Hedonic Value of Sucrose

Given inconsistent findings in published studies, we examined whether a personal lifetime history of alcohol dependence (AD) or a parental history of alcoholism affected preference for sweet solutions. Ninety-three alcohol-dependent subjects rated the intensity and hedonic value of five different sucrose solutions, which was compared with similar data from 122 subjects screened to exclude alcohol dependence. The effect of a family history of alcoholism (FH) was examined in the AD group. Neither the diagnosis of AD nor a family history of alcoholism was associated with ratings of sweetness intensity or sweet preference. These findings do not support the hypothesis that sucrose preference is positively associated with either a personal lifetime history of AD or a family history of alcoholism.

Parental History of Anxiety and Alcohol-Use Disorders and Alcohol Expectancies as Predictors of Alcohol-Related Problems

Research has consistently identified a family history of alcoholism as a risk factor for alcohol-related problems, and global positive expectancies have been found to moderate this association. High rates of comorbidity between alcohol use and anxiety disorders suggest that a family history of anxiety disorders may also increase risk. Further, expectations of negative reinforcement (e.g., tension reduction) have been found to moderate the influence of anxiety-related traits. The current study sought to extend previous research by examining the influence of parental history of alcoholism, anxiety disorders, and the combination, as predictors of alcohol-related problems. Expectancies of global positive changes and tension reduction were hypothesized to moderate the influence of parental history of alcoholism and anxiety, respectively. Direct interviews with parents assessed their history of alcoholism and anxiety for 144 offspring (ages 18-32; 53.5% male) creating four groups: those with a parental history of alcoholism (27.80%), anxiety (22.20%), both alcoholism and anxiety (33.30%), and no history of psychopathology (16.70%). Established measures assessed the offsprings'alcohol expectancies, alcohol use, and alcohol-related problems. Although expected interactions between parental alcoholism and global positive expectancies and between parental anxiety and tension-reduction expectancies were not found, global positive expectancies were associated with alcohol-related problems among the group with parental history of both alcoholism and anxiety. The results suggest that the relation between parental history of alcoholism and global positive expectancies observed in previous studies may be strongest among individuals with a comorbid parental history of alcohol and anxiety disorders. Incorporating expectancies into interventions targeting individuals with a comorbid parental history of alcohol and anxiety disorders may have utility.

Family History of Alcoholism Does Not Influence Adrenocortical Hyporesponsiveness in Abstinent Alcohol-Dependent Men

Background: Early abstinence in alcohol-dependent subjects is marked by adrenocortical hyporesponsivity. However, it is uncertain whether the blunted response is primarily attributable to a genetic vulnerability or to the chronic abuse of alcohol. In the present study, the authors investigated the influence of a family history (FH) of alcoholism upon suppressed glucocorticoid reactivity. Methods: Twenty-two abstinent alcohol-dependent and 14 control men were studied. The cortisol response was assessed in 11 patients following oCRH infusion (.4 ug/kg) and in a separate group of 11 patients following cosyntropin infusion (.01 ug/kg) preceded by high-dose intravenous dexamethasone (8 mg). FH, as determined by self-report, was assessed using two different methods: history of parental alcoholism and number of alcohol-dependent first- and second-degree relatives. Results: Neither a parental history or familial loading of alcoholism had a significant effect upon glucocorticoid responsivity in abstinent alcohol-dependent men. Conclusions: Adrenocorticol responsiveness in recently abstinent alcohol-dependent men does not appear to reflect a preexisting biologic vulnerability to alcoholism.

Alcoholism Risk Moderation by a Socio-Religious Dimension

Religious affiliation is inversely associated with the development of alcohol-dependence symptoms in adolescents, but the mechanisms of this effect are unclear. The degree to which religious affiliations accommodate to or differentiate from cultural values may influence attitudes about alcohol use. We hypothesized that, given permissive cultural norms about alcohol in the United States, if a religious affiliation differentiates itself from cultural norms, then high-risk adolescents (those with parents having a history of alcoholism) would exhibit fewer alcohol-dependence symptoms compared with other affiliations and nonreligious adolescents. A sample of female adolescent offspring (N = 3,582) in Missouri was selected. Parental alcoholism and religious affiliation and their interaction were examined as predictors of offspring alcohol-dependence symptoms. Findings indicated that (1) parental alcohol history robustly predicted increased offspring alcohol-dependence symptoms, (2) religious rearing appeared protective (offspring exhibited fewer alcohol-dependence symptoms), (3) religious differentiation accounted for most of the protective effect, (4) other religious variables did not account for the differentiation effect, and (5) black religious adolescents were more frequently raised with differentiating affiliations and exhibited greater protective effects. Results demonstrate that religious differentiation accounts for most of the protective influence of religious affiliation. This may be because religious differences from cultural norms (that include permissive alcohol norms) counteract these social influences given alternative "higher" religious ideals.

Alcohol outcome expectancies and risk for alcohol use problems in women with and without a family history of alcoholism

Studies have shown that alcohol expectancies are positively associated with drinking and alcohol abuse and dependence symptoms among alcohol users. This study looked at the relationship of alcohol expectancies, family history of alcoholism, menstrual cycle and drinking behavior. The present study compared alcohol expectancies using the Alcohol Expectancy Questionnaire (AEQ) in 85 women ranging from 18 to 35 years of age. Forty-one women had a confirmed parental history of alcoholism (family history positive, FHP) and 44 women had no parental history of alcoholism (family history negative, FHN). Participants’ mood, alcohol consumption, and daily consequences of alcohol use were prospectively tracked across one menstrual cycle. Alcohol expectancies at screening were significantly greater in FHP women in four of the six AEQ subscales, as well as the composite score. Alcohol expectancies correlated significantly with drinking behavior among FHN women. In FHP women, alcohol expectancies were elevated regardless of their drinking level. Alcohol expectancies decreased among FHP women, but not FHN women, after prospectively tracking their drinking behavior and consequences of drinking. Negative outcomes of drinking were increased among the FHP women who were heavy drinkers. Irrespective of family history status, alcohol use in moderate drinkers increased significantly during menses compared to the follicular and luteal phases of the menstrual cycle. These findings suggest that menstrual cycle may also play a role in alcohol consumption. Thus, the results of the present study indicate that issues related to the level of alcohol consumption, menstrual cycle phase and family history of alcoholism should be considered when addressing alcohol abuse in women.

Effects of Age and Parental History of Alcoholism on EEG Findings in Mission Indian Children and Adolescents

Many, but not all, Native American tribes have some of the highest rates of alcohol abuse and dependence. Yet, risk factors for the development of problem drinking in these high risk groups remain largely unknown. In primarily Euroamerican populations, electrophysiological variables have been associated with risk for alcoholism. The EEG has a specific developmental time course that has been described in a diverse set of ethnic groups, but it has not been described in Native American youth. In addition, the relationship between EEG development and risk for alcoholism in Indian youth has not been previously studied. Clinical ratings and spectral characteristics of the resting EEG were investigated in 140 Native American Mission Indian children and adolescents between the ages of 7 and 13 years. The specific aims of the study were to (1) investigate the relationship of age and gender with EEG spectral variables to determine if this population conforms to similar trends from previously published data in other ethnic groups and (2) to determine whether children with a parental history of alcoholism differ from those without alcoholic parents on EEG spectral parameters. No excess of abnormal EEG activity was found in this sample of Native American youth. Age, but not gender, was found to have a significant effect on EEG spectral characteristics with younger children (7-11 years old), having significantly more power in slow activity (0.5-7.5 Hz) and in alpha power (8-12 Hz) as well as slower alpha frequencies than older children (12-13 years old). Consistent with other studies of Native American youth, 66% of the children and adolescents participating in this study had at least one parent who had a lifetime diagnosis of alcohol dependence. However, an ANCOVA that covaried for age and gender revealed no significant differences in power or frequency characteristics of the EEG on the basis of parental history of alcoholism. These studies suggest that this sample of Mission Indian children, despite high levels of parental alcohol dependence and low socioeconomic status, show normal EEG development. As yet, no relationship has been found between any specific EEG phenotype and parental history of alcoholism in this population, however, further EEG maturation may be necessary before any relationships can be fully delineated.

Peripheral neuropathy in chronic alcoholism: a retrospective cross-sectional study in 76 subjects.

A consecutive sample of 76 chronic alcoholic patients was studied clinically, biochemically and electrophysiologically to assess clinical and/or subclinical signs of alcohol-related neuropathy as well as the most important and disputed risk factors for neuropathy such as age, parental history of alcoholism, nutritional status, alcoholic disease duration and total lifetime dose of ethanol (TLDE). The results show that alcohol-related neuropathy, especially when subclinical, seems to be frequent and mostly characterized by axonal degeneration of peripheral nerve fibres with earlier and more frequent involvement of sensory fibres and lower limbs. Moreover, positive family history of alcoholism, but above all alcoholic disease duration and TLDE, could be more important factors than malnutrition in determining neuropathy.
