Risky Behaviors: Smoking and Alcohol

Study Notes

Risky Behaviors

Smoking: Men smoke more than women, with 70% of men smokers in 1945 declining to 12% in 2019.
Reasons for smoking:
- Sociocultural factors: Exposure to smoking in media normalizes the behavior, impacting likelihood; descriptive norms (what people do) versus injunctive norms (what people approve of).
- Reinforcement: Smoking offers relaxation, but this effect is often not greater than a non-smoker, or neutral
- Weight control: Quitting smoking can lower cravings and weight gain, although ongoing smoking and subsequent weight gain are still a significant concern.
- Nicotine dependence: This is a factor in the ongoing use of smoking.
Quitting smoking: Long-term success rates for quit strategies are only 15-20%
Preventing smoking uptake: Interventions like self-efficacy and implementation intentions; this particular type of intervention had the best outcomes when used to prevent smoking initiation

Alcohol Consumption

Prevalence: 62% of Australians drank alcohol in the past week; 80% in the past year.
Risky drinking behavior: Often defined as 5 or more drinks in a row; the drinking pattern is often more damaging than a single occasion, ranging from 20-40% involvement.
Effects of alcohol:
- Initial: Positive, outgoing, reduced inhibition
- Continued: Depressant, impaired coordination and judgment
- Alcohol myopia: Narrowed attention to immediate stimuli, affecting judgment.
- Long-term: Adverse effects on all organs, increasing mortality risk.
Health benefits: Moderate use may potentially decrease Low-density lipoprotein (LDL)
Global impact: 2.5 million net deaths globally related to alcohol use, with an adjustment for some health benefits, 2.25 million.
Costs: $36 billion annually in Australia due to alcohol-related issues; incidents like assaults, domestic violence, child abuse, and hospitalizations. Costs likely higher than the reported amounts.

Sexual Behavior

Prevalence: Significant proportions of adolescents engage in sexual activity, with rates increasing through high school; year 10 students at 25% and year 12 at 50%.
Condom use: Low rates of consistent condom use among high school seniors (40%).
Alcohol/Substance use: High correlation of risky sexual behavior with alcohol or drug use and intoxication.
Barriers to safe sex:
- Unrealistically optimistic risk perception: Individuals under-estimate their risk for infections.
- Decreased perceived risk of STIs: Particularly concerning and impacting HIV/AIDS risk reduction strategies
- Beliefs that condoms reduce pleasure: Incorrect perceptions regarding condoms' effect on sexual experience.
- Concerns about initiating discussions around safe sex practices

Sleep

Definition of sleep: A reversible behavioral state characterized by perceptual disengagement and unresponsiveness to the environment.
Stages of sleep:
- NREM (non-rapid eye movement): Further divided into stages marked by distinct brainwave patterns and changes in physiological parameters
- REM (rapid eye movement): Associated with dreaming, rapid eye movements, and distinctive brainwave patterns, important for memory consolidation and brain plasticity.
Sleep duration by age: Varies across stages of life, from infancy to later adulthood.
Functions of sleep:
- Inactivity theory: Evolutionary protection for safety.
- Energy conservation theory: Reduction of energy consumption. reduced metabolic rate
- Brain plasticity theory: Facilitates adaptation to environments, crucial for learning, memory, and cognitive function. Improves the brain's ability to adapt to its environment.
- Restoration theory: Restores bodily function, repairs tissue, and removes toxins.
Consequences of sleep deprivation: Impaired cognitive functions, increased risk for physical illness and death, with direct correlation with sleep duration and life expectancy

Insomnia

Definition (DSM-5): A dissatisfaction with sleep quantity or quality, associated with difficulty initiating, maintaining sleep, or early-morning awakening, present 3 nights a week for 3 months despite adequate opportunities to sleep and causing difficulties in daily functions.
Prevalence: Affects approximately 20% of the population
Causes of Insomnia:
Hyperarousal: Emotional, cognitive, and physiological arousal, contributing to difficulty falling asleep.
Sleep impairing cognitions: Thoughts about sleep loss, consequences, expectations, etc.
Dysfunctional sleep habits: Irregular schedules and napping habits, can impact sleep regularity negatively.
Cognitive Behavioral Therapy for Insomnia (CBT-I): This form of therapy is a useful treatment for insomnia
