3. 3 Achievement and Physical Health: 1. Are there sex differences in self-esteem? (continued) 2. Are there sex differences in mortality and morbidity?

4. 4 By the end of today’s class, you should be able to: 1. review explanations for sex differences in global self- esteem. 3. define the term “morbidity paradox.” 2. identify sex differences in domain-specific forms of self- esteem.

5. 5 5. contrast sex differences in mortality rates in distinct regions of the world. 4. discuss sex differences in mortality rates across the life span among Canadians.

6. 6 Explanations for the lower levels of global self-esteem among females than males: 1.Gender roles. 2. Imbalances in cross-sex interactions in childhood. 3. Differential treatment of boys and girls in school. Are there sex differences in self-esteem? (continued)

7. 7 5. Pervasive violence against girls and women. 4. Differential athletic participation by boys and girls. 6. Cultural emphasis on appearance among females: Body dissatisfaction is so common among females that it has been termed a “normative discontent” (Rodin et al., 1985).

8. 8 Nevertheless, the relatively small sex difference in global self-esteem has led some theorists to caution against excessive focus upon it. This may: 2. Lead to self-fulfilling prophecies among females: 1. Result in neglect of the challenges to self-esteem that are experienced by boys and men. Females obtain higher scores than males on some domain-specific forms of self-esteem:

10. 10 Are there sex differences in mortality and morbidity? Although males have higher mortality rates than females, females have higher morbidity rates than males.

11. 11 1.Mortality  More males are conceived than females: (100 females:120-160 males; Stillion, 1995).  However, birth rates (100 females:105 males) suggest that male fetuses are more likely to die than female fetuses (Matthews & Hamilton, 2005).  After birth, death rates are higher for males than females at all ages, with the exception of >85 years.

15. 15  Sex differences in life expectancy are more variable in “developing” countries than in developed countries. Nevertheless, in the vast majority of countries, females outlive males:
