NIAAA’s Strategic 5-year Plan
“A lifespan perspective will allow researchers to identify how the emergence and progression of drinking behavior is influenced by changes in biology, in psychology, and in exposure to social and environmental inputs over a person’s lifetime, and vice versa.”
“This approach should help researchers discover life stage-appropriate strategies for identifying, treating, and preventing alcohol use disorders.”

on Much is not specific to alcohol, but related to other problems in childhood (e.g. aggression, impulsivity, conduct disorder)
During this age period, expectations about effects of alcohol are learned
Early use this young may affect developing brain structures
Social-environmental factors (family, peers, school, community, culture)
Multilevel dynamic interplay
Points to keep in mind

Monitoring the future 2005
Three out of every four 12th grade students (75%) have at least tried alcohol
Four tenths (41%) of 8th graders have tried alcohol
Been drunk at least once:– 58% of 12th graders– 41% of 10th graders– 20% of 8th graders
![Page 12: Alcohol use and disorder across the lifespan](https://reader030.vdocuments.site/reader030/viewer/2022032414/56813364550346895d9a7b14/html5/thumbnails/12.jpg)
Monitoring the Future, 2005
Daily drinking is infrequent – .5 – 3.1% of students
Binge drinking much more common: 5+ drinks in a row in the past 2 weeks– 28% of 12th graders– 21% of 10th graders– 11% of 8th graders

Adolescent Cognition: Time of Development and Vulnerability
Formal operations not yet in place Brain development continues into the 20s
– Myelination develops prefrontally through the adolescent period
– Enhanced connectivity and organization in specific regions
– Synaptic pruning, especially prefrontally– Pruning + experience adult
efficient/organized/specialized (Luna, Giedd) Ability to assess risk and apply effective decision-
making potentially immature– Estimates of norms for substance use are biased
![Page 18: Alcohol use and disorder across the lifespan](https://reader030.vdocuments.site/reader030/viewer/2022032414/56813364550346895d9a7b14/html5/thumbnails/18.jpg)
Deviance Proneness
Problem behavior theory (Jessor et al., 1977)– Problem behaviors co-occur in
adolescence– Risk processes overlap (behavior
problems, school difficulties, family adversities/stresses/ psychopathologies)
– Empirical support plentiful (e.g., Petraitis et al. 1995, for review).

strategies
Peer influence processes (selection and influence)
Broader socialization networks (school and community activities such as after-school sports and religious organizations)

Stress and Affect Regulation
Stress model of drinking – complicated with inconsistent support– Parental alcoholism negative life
events/perceived stress alcohol use• Stress or marker for dysfunction/impairment?• Stress measurement/time lag (Hussong et al 2001)
• Inconsistent support for responsivity to stress and prospective role of mood/anxiety
• More refined measurement of stress, affect, and biological underpinnings (e.g., type and severity of negative affect)

Treatment of adolescents with AUD
No one treatment approach stands out over others
Optimal dosage and length of treatment unclear
Comorbidities not well researchedPharmacotherapy studies small in number
(e.g., a few studies of SSRIs for AUD and depression; stimulants being tested)

Emerging Adulthood
Period from the end of secondary school through the attainment of “adult” status (age 18-25)
Bridges adolescence and adulthood Marked by frequent change and
exploration Assumption of adult roles and
responsibilities
![Page 25: Alcohol use and disorder across the lifespan](https://reader030.vdocuments.site/reader030/viewer/2022032414/56813364550346895d9a7b14/html5/thumbnails/25.jpg)
Why This New Developmental Stage? Delay in marriage, parenthood
– Increases in education – Changes in women’s roles– Birth control pill, standards of sexual
morality Increased desire for independence,
freedom
![Page 26: Alcohol use and disorder across the lifespan](https://reader030.vdocuments.site/reader030/viewer/2022032414/56813364550346895d9a7b14/html5/thumbnails/26.jpg)
Many Developmental Tasks Occur During this Stage Identity exploration & formation Freedom to choose new behaviors &
lifestyles New social networks Separation from families & friends Education, intellectual growth
![Page 27: Alcohol use and disorder across the lifespan](https://reader030.vdocuments.site/reader030/viewer/2022032414/56813364550346895d9a7b14/html5/thumbnails/27.jpg)
Drinking Can be Maladaptive
Failure to master tasks frustration and stress alcohol use
Alcohol use failure to master tasks frustration and stress
Long-term effects on physical & psychological well-being; implications for attainment of traditional adult roles

Role compatibility theory (Kandel) Role socialization
– Individuals change substance use to be compatible with expectations from the social roles
Role selection – Individuals with pre-existing traits
(including low substance use) select into certain roles

Midlife
Adapted from presentation byTheodore Jacob, Ph.D.VA Palo Alto Medical Health Care System

But What Happens After 30 ?
Are these identified patterns (trajectories) stable after young adulthood or does variability and change continue?
Do other drinking pathways emerge at later ages which could not be anticipated from young adult studies?
What historical and dynamic variables allow for prediction of which alcoholics will follow what trajectories for what length of time?
![Page 45: Alcohol use and disorder across the lifespan](https://reader030.vdocuments.site/reader030/viewer/2022032414/56813364550346895d9a7b14/html5/thumbnails/45.jpg)
Why So Little Interest in Alcoholism at Midlife?
– Alcoholism was viewed as a unitary disorder– Less “payoff” studying midlife alcoholism– Stage-specific issues (e.g. maturation) are
fewer at midlife making specification of this time period difficult
![Page 46: Alcohol use and disorder across the lifespan](https://reader030.vdocuments.site/reader030/viewer/2022032414/56813364550346895d9a7b14/html5/thumbnails/46.jpg)
Class Results
Analyses yielded a 4-class solution: Severe, Chronic Alcoholics (SCAs) Young Adult Alcoholics (YAAs) Late Onset Alcoholics (LOAs) Severe, Nonchronic Alcoholics
(SNCAs)
![Page 47: Alcohol use and disorder across the lifespan](https://reader030.vdocuments.site/reader030/viewer/2022032414/56813364550346895d9a7b14/html5/thumbnails/47.jpg)
Results
Four different drinking trajectories were supported
Three trajectories have previous empirical support
1. Most notable was the Severe Chronic Alcoholism type that exhibited early onset, persistent duration, likelihood of comorbid ASP disorder, and paralleled Zucker’s Antisocial Alcoholism

Treatment for Older Adults with Abuse/Dependence Generally older adults do as well or better than
younger adults in treatment. Predictors of better outcomes
– Longer treatment– Greater involvement in after-care programs– Female gender– Social network that does not encourage alcohol use

Moderate Alcohol Use and CHD
Light to moderate (~1 drink) regular (most days) alcohol consumption linked to favorable CHD outcomes.
Moderate alcohol intake linked to increase in HDL and reduced platelet aggregation and increased fibrinolysis.

Conclusions
40-60% of older persons drink alcohol In cohort studies alcohol has benefits or
risks in regard to CHD and CHD-related outcomes depending on amount and frequency of alcohol use
Alcohol is a risk for many other disease outcomes
![Page 67: Alcohol use and disorder across the lifespan](https://reader030.vdocuments.site/reader030/viewer/2022032414/56813364550346895d9a7b14/html5/thumbnails/67.jpg)
Conclusions (cont)
Most older drinkers are not at-risk because they would meet criteria for alcohol abuse or dependence, but rather because of the amount of alcohol they drink given their other medical conditions
More data needed on the effect of alcohol use and multiple comorbidity on health outcomes

Summary of MLDA research
-- Deaths go up when MLDA is lowered, go down when it is raised
-- Higher MLDA results in lower alcohol consumption
-- Benefits accrue not only to those directly affected by the law (18-20 year olds) but also to those not directly affected – 16-17 year olds

Initial Experience with Alcohol
10% of 9-10 year olds have had alcohol (Donovan, 2004)
1/3 of youth begin drinking before age 13– Normative experimentation vs problem
exposure– Sips vs drinks– Initial sips at young age, occurring in family
context, not associated with risk factors for problem drinking (Donovan & Molina, under review)
![Page 93: Alcohol use and disorder across the lifespan](https://reader030.vdocuments.site/reader030/viewer/2022032414/56813364550346895d9a7b14/html5/thumbnails/93.jpg)
Early Initiation into Alcohol
Drinking alcohol (more than a sip or taste) at an early age (~ before age 14) predicts– Heavier drinking and other drug use in
adolescence (Robins & Pryzbeck, 1985; Hawkins et al 1997)
– Adult alcohol dependence (Grant & Dawson, 1998)
– Other adverse outcomes such as vehicular crashes after drinking (Hingson et al., 2002, Accid Anal Prev)
