3. 3 Physical Health: 1. What factors account for sex differences in health? (continued)

4. 4 By the end of today’s class, you should be able to: 1. review health behaviours that may contribute to sex differences in mortality and morbidity. 4. discuss sex differences in overweight and obesity rates. 3. explain the greater susceptibility to alcohol-related impairments among females than males. 2. discuss sex differences in alcohol and drug use rates.

5. 5 (c) Alcohol and Other Drug Use What factors account for sex differences in health? (continued)  The prevalence of alcohol and other drug use has declined in Canada in recent years (Statistics Canada, 2009). 2. Health Behaviours (continued)

6. 6  Males are more likely than females to consume alcohol and illicit drugs; females are more likely than males to consume psychoactive pharmaceutical drugs.

MalesFemales Alcohol (any amount, past 30 days)70.658.6 Alcohol (any amount, past 12 months)81.473.5 Alcohol (heavy drinking, 5 or more drinks on one occasion, at least once a month, past 12 months) 26.811.4 Illicit drugs (e.g., cannabis, cocaine/crack, speed, ecstasy, hallucinogens, heroin; past 12 months) 15.39.1 Pharmaceutical drugs (pain relievers, stimulants, sedatives; past 12 months) 24.4 (0.5 to get high) 32.1 (0.6 to get high) Rates of Alcohol and Drug Use by Sex, (Statistics Canada, 2008, 2012) 7

8. 8  Consistent with the greater alcohol and illicit drug use among males than females, males are more likely than females to be (Statistics Canada, 2009): alcohol dependent (3.9% vs. 1.3%) illicit drug dependent (1.1% vs. 0.5%)

9. 9 Females become more quickly addicted to alcohol and drugs than males and experience more adverse health consequences (e.g., brain atrophy) from alcohol than males.  Females are more likely than males to receive treatment for drug abuse.  Females are more vulnerable to the acute and chronic effects of alcohol and other drugs (Nolen- Hoeksema & Hill, 2006; Roth et al., 2004):

10. 10 (d) Overweight, Obesity, and Exercise  Healthy vs. unhealthy weight is determined by the body mass index (BMI): BMI = weight (kg) / height (m) 2 Overweight = BMI of 25 to 29.9 Obese = BMI ≥ 30

11. 11  Rates of overweight and obesity have increased substantially in Canada over the last 3 decades.  Males are more likely than females to be overweight. Males and females do not differ significantly in rates of obesity (Statistics Canada, 2011).
