Vulnerability of NCDs and Mediating Effect of Risk Behaviors Among Tuberculosis Patients and Their Household Contacts Compared to the General Population in the Yangon Region, Myanmar

Purpose

We investigated the association of TB patients and their household contacts with diabetes mellitus (DM) and hypertension compared to the general population, and the mediating effects of risk behaviors including current smoking, alcohol drinking, and poor diet quality.

Patients and Methods

A cross-sectional study on screening for DM, hypertension, and risk behaviors among newly diagnosed TB patients (n = 221) and their household contacts (n = 257) aged 25-74 years in Yangon in 2018. Health data of the general population (n = 755) were obtained from an NCD risk factor survey in Yangon. A directed acyclic graph is used to identify possible pathways of association between variables. Associations are presented as adjusted odds ratios (aOR).

Results

Compared to the general population, both TB patients and their household contacts were associated with current smoking and drinking, and TB patients were more likely to be underweight. Without considering mediating effects, TB patients had higher odds of DM (aOR = 6.3, 95% CI: 3.8-10.6), but both TB patients and household contacts had lower odds of hypertension (aOR = 0.54; 95% CI: 0.33-0.87) and (aOR = 0.68; 95% CI: 0.47-0.98), respectively. The body mass index-mediated pathway reduced the odds of DM and hypertension among TB patients (aOR = 3.4; 95% CI: 2.2-5.3) and (aOR = 0.3; 95% CI: 0.2-0.5), respectively.

Conclusion

The shared risk behaviors among TB patients and household contacts with high burden of DM in TB patients endorse screening of risk behaviors and strengthening the integration of NCD services among TB patients and household contacts in this dual-burden country.

Alcohol family history moderates the association between evening substance-free reinforcement and alcohol problems

Behavioral economic theories of substance abuse posit that deficits in substance-free reward increase risk for substance misuse, but little research has examined potential moderators of this relationship, including dispositional risk factors. Here, we tested the hypothesis that young adult heavy drinkers with family histories of alcohol misuse would show a stronger association specifically between low evening substance-free reinforcement and alcohol problems compared to those without a family history of alcohol misuse. Participants were 317 college students reporting heavy episodic drinking (Mage = 18.8, SD = 1.1, 61% female, 79% White) who completed a questionnaire about engagement and enjoyment in rewarding activities not involving substance use after 7 p.m., along with measures of personal and parental alcohol use/problems. Evening substance-free reinforcement was negatively associated with typical drinking level for women, but not for men. Family history status did not show a significant association with typical alcohol consumption or evening substance-free reinforcement (operationalized as activity participation × enjoyment), but did show a significant association with alcohol problems. Evening substance-free reinforcement was significantly negatively related to alcohol problems for both men and women. However, the presence of a family history of alcohol misuse moderated this relationship, such that only individuals with familial risk for alcohol misuse who reported lower evening substance-free reinforcement evidenced greater alcohol-related problems. These findings suggest that lower evening substance-free reinforcement is associated with alcohol misuse among young adults, and that this association is exacerbated among individuals with familial risk for developing alcohol problems.

Cognitive and behavioural dispositions in offspring at high risk for alcoholism

OBJECTIVES

Offspring with family history of alcoholism are considered to be at high risk for alcoholism. The present study sought to expand our understanding of cognitive and behavioural dispositions associated with executive control and self-regulation in alcohol naïve offspring with and without family history of alcoholism.

METHODS

Sample comprised of alcohol naive offspring in two groups: (i) at high risk (n = 34) and (ii) at low risk for alcoholism (n = 34). Both groups were matched on age (+/-1 year), education (+/-1 year) and gender. Measures used were: Mini-International Neuropsychiatric Interview, Family Interview for Genetic Studies, Socio-demographic Data Sheet, Annett's Handedness Questionnaire, Barratt's Impulsiveness Scale-version 11, Digit Span Test, Spatial Span Test, Tower of London, Wisconsin Card Sorting Test, Iowa Gambling Task (IGT) and Game of Dice Task (GDT).

RESULTS

Results showed that alcohol naive offspring at high risk for alcoholism reported significantly high impulsivity and demonstrated significant differences on executive functions and decision making tasks. Correlation analysis revealed that high impulsivity was significantly associated with poor performance on explicit decision making task (GDT) and executive function task (WCST). There was no significant correlation between two decision making tasks (IGT and GDT) in both groups and performance on IGT was not significantly associated with impulsivity and executive functions.

CONCLUSIONS

The present study indicates cognitive and behavioural dispositions in alcohol naive offspring at high risk for alcoholism and support the sub-optimal balance between reflective and impulsive system responsible for addiction. Furthermore, present study supports separability between two different types of decision making tasks.

Family history density of substance use problems among undergraduate college students: Associations with heavy alcohol use and alcohol use disorder

PURPOSE

A family history of alcoholism has been found associated with problematic alcohol use among college students, but less research has examined the effects of family history density of substance use problems in this population. This study examined the prevalence of family history density of substance use problems and its associations with heavy alcohol use, negative alcohol consequences, and alcohol use disorder in a college sample.

METHODS

Based on a secondary analysis of a probability sample, data were analyzed from 606 undergraduate students. Family history density of substance use problems included both first and second degree biological relatives. Heavy alcohol use was the total number of days in which participants drank five/four or more drinks for men/women, negative alcohol consequences were derived from items commonly asked in college student surveys, and an alcohol use disorder was defined as meeting diagnostic criteria for alcohol abuse or dependence. Point prevalence estimated rates of family history density of substance use problems, and negative binomial, ANCOVA, and logistic regression models examined associations between family history density and the alcohol variables while adjusting for sociodemographic variables.

RESULTS

Family history density of substance use problems was not significantly associated with total days of heavy alcohol use. Having a second degree, a first degree, or both a first and second degree relative(s) with a substance use problem, however, was significantly associated with experiencing negative alcohol consequences. In addition, having both a first and second degree relative(s) with a substance use problem significantly increased the odds of having an alcohol use disorder.

CONCLUSIONS

Family history density of substance use problems may play a role in experiencing negative alcohol consequences and in having an alcohol use disorder among undergraduate college students and may be an important risk factor to assess by college health professionals.

Neurobiological phenotypes associated with a family history of alcoholism

BACKGROUND

Individuals with a family history of alcoholism are at much greater risk for developing an alcohol use disorder (AUD) than youth or adults without such history. A large body of research suggests that there are premorbid differences in brain structure and function in family history positive (FHP) individuals relative to their family history negative (FHN) peers.

METHODS

This review summarizes the existing literature on neurobiological phenotypes present in FHP youth and adults by describing findings across neurophysiological and neuroimaging studies.

RESULTS

Neuroimaging studies have shown FHP individuals differ from their FHN peers in amygdalar, hippocampal, basal ganglia, and cerebellar volume. Both increased and decreased white matter integrity has been reported in FHP individuals compared with FHN controls. Functional magnetic resonance imaging studies have found altered inhibitory control and working memory-related brain response in FHP youth and adults, suggesting neural markers of executive functioning may be related to increased vulnerability for developing AUDs in this population. Additionally, brain activity differences in regions involved in bottom-up reward and emotional processing, such as the nucleus accumbens and amygdala, have been shown in FHP individuals relative to their FHN peers.

CONCLUSIONS

It is critical to understand premorbid neural characteristics that could be associated with cognitive, reward-related, or emotional risk factors that increase risk for AUDs in FHP individuals. This information may lead to the development of neurobiologically informed prevention and intervention studies focused on reducing the incidence of AUDs in high-risk youth and adults.

Re-examining religiosity as a protective factor: comparing alcohol use by self-identified religious, spiritual, and secular college students

Religiosity has been found to be associated with lower alcohol use by college students. The majority of studies on this topic, however, fail to differentiate religiosity and spirituality. This is potentially problematic due to the changing face of religion in America today. A study was conducted to explore similarities and differences between self-identified religious and spiritual college students. A modified version of the Core Alcohol and Drug Survey was administered online with a sample of 2,312 students. As hypothesized, self-identified religious and spiritual students differed significantly on key variables related to religious practices, alcohol consumption, and postmodern social values.

Contribution of time of drinking onset and family history of alcohol problems in alcohol and drug use behaviors in Argentinean college students

AIMS

The aim of the study was to analyze independent and potential interactive effects of age at drinking onset and family history of alcohol abuse on subsequent patterns of alcohol drinking, alcohol-related problems and substance use.

METHODS

Participants were college students (60.3% females, mean age = 20.27 ± 2.54 years) from the city of Córdoba, Argentina. Several measures were used to assess alcohol, tobacco and drug use. The Spanish version of the Brief Young Adult Alcohol Consequences Questionnaire was used to assess alcohol-related problems. Factorial analyses of variance, or its non-parametric equivalent, were performed to explore differences in substance use behaviors and alcohol-related problems in subjects with early or late drinking onset and with or without family history of alcohol abuse. Chi-square tests were conducted to analyze the association between these two risk factors and categorical measures of alcohol, tobacco and drug use.

RESULTS

Early onset of drinking was associated with amount of consumption of alcohol including up to hazardous levels, as well as tobacco and drug use. However, the frequency of alcohol problems and frequency of episodes of alcohol intoxication were only related to age of onset in those with a positive family history of alcohol problems.

CONCLUSION

Delaying drinking debut is particularly important in the prevention of future alcohol problems in those adolescents who have a family history of such problems.

Does family history of alcohol problems influence college and university drinking or substance use? A meta-analytical review

AIMS

Family history of alcohol use problems is a reliable determinant of alcohol use and problems in the population at large, but findings are inconsistent when this issue is examined in college and university students. No quantitative summary of this literature has been reported to date. The purpose of this study was to conduct a meta-analysis on the effects of family history on substance use and abuse in college and university students.

METHODS

A two-group contrast meta-analysis was conducted to evaluate the differences in substance use and abuse between family history-positive and -negative students pursuing higher education. The studies that contributed data to this meta-analysis were conducted in five countries, with the majority of studies from the United States. A total of 65 published papers (53 samples) contributed data from 89 766 participants attending university or college. Effect sizes were coded for alcohol consumption, problems and use disorder symptoms, as well as other illegal drug use and abuse. Two independent coders calculated effect sizes and coded descriptive content about the papers, and discrepancies were reconciled. Family history was used as the grouping variable.

RESULTS

Family history had a minimal effect on alcohol consumption, with stronger effects on alcohol consequences (Cohen's d: 0.21-0.25), alcohol use disorder symptoms (Cohen's d: 0.24) and other drug involvement (Cohen's d: 0.37-0.86).

CONCLUSIONS

Relative to students without a family history of alcohol problems, students with positive family histories do not drink more, but may be at greater risk for difficulties with alcohol and drugs.

Risky decision-making: an FMRI study of youth at high risk for alcoholism

BACKGROUND

Adolescents with a family history of alcoholism (FHP) are at risk for developing an alcohol use disorder (AUD), and some studies indicate that FHP individuals show deficits in executive functioning. The ability to make adaptive decisions is one aspect of successful executive functioning that is often measured during risk-taking tasks; however, this behavior has not been examined in FHP youth. As impaired decision-making could predispose FHP youth to make poor choices related to alcohol use, the current study examined the neural substrates of risk-taking in FHP adolescents and their family history negative (FHN) peers.

METHODS

Thirty-one (18 FHP, 13 FHN) youth between 13 and 15 years old were included in this study. All youth had used little to no alcohol prior to study involvement. Functional magnetic resonance imaging was used to examine the neural substrates of risk-taking during the Wheel of Fortune (WOF) decision-making task (Ernst et al., 2004) in FHP and FHN youth.

RESULTS

FHP youth did not differ from FHN youth in risk-taking behavior, but showed less brain response during risky decision-making in right dorsolateral prefrontal cortex and right cerebellar regions compared with FHN peers.

CONCLUSIONS

Despite no behavioral differences on the WOF decision-making task, FHP youth exhibited atypical neural response during risk-taking compared with FHN peers. Atypical brain activity, in regions implicated in executive functioning could lead to reduced cognitive control, which may result in risky choices regarding alcohol use. This could help explain the higher rates of AUDs seen in FHP adolescents. Further examination of risky behavior and associated brain response over the course of adolescence is necessary to characterize the vulnerabilities of FHP youth in the absence of alcohol abuse.

Identifying factors that increase the likelihood of driving after drinking among college students

Driving after drinking (DAD) is a serious public health concern found to be more common among college students than those of other age groups or same-aged non-college peers. The current study examined potential predictors of DAD among a dual-site sample of 3753 (65% female, 58% Caucasian) college students. Results showed that 19.1% of respondents had driven after 3 or more drinks and 8.6% had driven after 5 or more drinks in the past 3 months. A logistic regression model showed that male status, fraternity or sorority affiliation, family history of alcohol abuse, medium or heavy drinking (as compared to light drinking), more approving self-attitudes toward DAD, and alcohol expectancies for sexual enhancement and risk/aggression were independently associated with driving after drinking over and above covariates. These results extend the current understanding of this high risk drinking behavior in collegiate populations and provide implications for preventive strategies. Findings indicate that in addition to targeting at-risk subgroups, valuable directions for DAD-related interventions may include focusing on lowering both self-approval of DAD and alcohol-related expectancies, particularly those associated with risk/aggression and sexuality.

Stress and consumption of alcohol in humans with a Type 1 family history of alcoholism in an experimental laboratory setting

BACKGROUND

This paper investigates how stress interacts with alcohol consumption in subjects with a family history of alcoholism. One mechanism for increases in alcohol intake may be that stress alters the subjective effects produced by the drug.

METHODS

58 healthy volunteers, divided into two groups of family history positive (FHP) and two groups of family history negative (FHN) participated in two laboratory sessions, in which they performed in one out of two sessions a stress task. Then subjects were allowed to choose up to six additional drinks of ethanol or placebo depending on which session they were randomly assigned to start with.

RESULTS

It was found that FHP subjects increased their consumption of alcohol after stress.

CONCLUSIONS

It is possible that both stress and alcohol specifically exaggerate the feelings of the reward in the FHP individuals in such way that it may increase the likelihood of consuming more alcohol.

Response to alcohol in women: role of the menstrual cycle and a family history of alcoholism

The present study determined whether: (1) the response to alcohol varied as a function of menstrual cycle phase and (2) women with a paternal history of alcoholism (FHP) were less sensitive to the effects of alcohol compared to women without a family history of alcoholism (FHN). The behavioral effects of alcohol (0.00, 0.25, and 0.75 g/kg) were evaluated in 21 FHN and 24 FHP women; each dose was tested during both the midfollicular and late luteal phases of the menstrual cycle. Baseline negative mood was increased during the luteal phase compared to the follicular phase (increased Beck Depression scores and decreased Vigor, Arousal, and Friendly scores). Alcohol increased ratings of Drug Liking and Good Drug Effect more in the luteal phase than the follicular phase. FHP women had greater negative mood during the luteal phase and some of these dysphoric effects were increased by alcohol more in FHP women than FHN women. Alcohol impaired performance, with no group or menstrual cycle differences. However, consistent with previous studies, FHP women were less impaired by alcohol than FHN women on the balance task. These data indicate that (1) the differences in response to alcohol across the menstrual cycle are subtle, although alcohol is liked more during the luteal phase; (2) increases in dysphoric mood during the luteal phase are more pronounced in FHP women compared to FHN women, particularly after alcohol; and (3) the differences observed in response to alcohol between FHP and FHN women are less pronounced than previously shown in men.

Family history of alcohol abuse associated with problematic drinking among college students

Studies examining family history of alcohol abuse among college students are not only conflicting, but have suffered various limitations. The current report investigates family history of alcohol abuse (FH+) and its relationship with alcohol expectancies, consumption, and consequences. In the current study, 3753 student participants (35% FH+), completed online assessments. Compared to FH- same-sex peers, FH+ males and FH+ females endorsed greater overall positive expectancies, consumed more drinks per week, and experienced more alcohol-related negative consequences. Further, FH+ females evaluated the negative effects of alcohol to be substantially worse than FH- females. An ANCOVA, controlling for age, GPA, race, and alcohol expectancies, resulted in family history main effects on both drinking and consequences. An interaction also emerged between gender and family history, such that FH+ males were especially vulnerable to high levels of alcohol consumption. Results reveal the scope of FH+ individuals in the college environment and the increased risk for these students, particularly male FH+ students, suggesting a need for researchers and college health personnel to focus attention and resources on this issue.

The motivational context for mandated alcohol interventions for college students by gender and family history

OBJECTIVE

Alcohol interventions to reduce drinking for college students sanctioned for alcohol use reduce drinking and/or problems. However, intrinsic motivation to change cannot be assumed if students are mandated to receive interventions. The purpose of this study was to explore the influence of both gender and family history on motivational variables prior to a mandated intervention.

METHOD

Participants were 677 students (63% male) who violated residence hall alcohol policy and were mandated to participate in an alcohol abuse prevention intervention. During a baseline assessment, students described their drinking patterns and completed an assessment of biological risk for alcohol problems; they also reported attitudes regarding the sanction event, perceived peer norms regarding sanctions, resistance to influences on their alcohol use, motivation to change alcohol use, and decisional balance regarding current alcohol use.

RESULTS

Many gender differences emerged on the motivational variables suggestive of more motivation to change among female students; family history was related only to drinking patterns and decisional balance.

CONCLUSIONS

If motivational factors influence receptivity and response to mandated interventions, then these finding suggest that greater attention to enhancing motivation to change in male students is warranted.

Family history of alcohol abuse moderates effectiveness of a group motivational enhancement intervention in college women

This study examined whether a self-reported family history of alcohol abuse (FH+) moderated the effects of a female-specific group motivational enhancement intervention with first-year college women. First-year college women (N=287) completed an initial questionnaire and attended an intervention (n=161) or control (n=126) group session, of which 118 reported FH+. Repeated measures ANCOVA models were estimated to investigate whether the effectiveness of the intervention varied as a function of one's reported family history of alcohol abuse. Results revealed that family history of alcohol abuse moderated intervention efficacy. Although the intervention was effective in producing less risky drinking relative to controls, among those participants who received the intervention, FH+ women drank less across five weeks of follow-up than FH- women. The current findings provide preliminary support for the differential effectiveness of motivational enhancement interventions with FH+ women.
