Body mass index, disordered eating behavior, and acquisition of health information: examining ethnicity and weight-related issues in a college population

OBJECTIVE AND PARTICIPANTS: To investigate ethnic differences related to weight, the authors assessed body mass index, dysfunctional eating, receipt of health information, and perceived obstacles to healthy lifestyles of 210 ethnically diverse college women. METHODS: The authors used the Eating Attitudes Test to assess dieting, food preoccupation, and bulimic behaviors. RESULTS: The authors found no ethnic differences in body mass index or disordered eating, but African Americans were more likely than were European Americans and Latina Americans to receive nutrition information from professionals and less likely than European Americans to perceive time as an obstacle. Overall, receipt of health information from a professional was related to fewer disordered eating behaviors; however, the specific eating behavior that was reduced varied by ethnicity. CONCLUSIONS: Health professionals should reconsider traditional assumptions of disordered eating behavior as a European American problem and consider cultural appropriateness in the development of effective health programs.     

Philanthropic racism in Britain: The Liverpool university settlement,the anti‐slavery society and the issue of ‘half‐caste’ children, 1919–51

The history of racial ideology in Britain has focused mainly on extreme groups of the political right. Less attention has been paid to more ‘respectable’ forms of racism. This paper attempts to redress the balance. It concentrates upon two groups, the Anti‐Salvery Society and the Settlement Movement and, with particular reference to Liverpool and Cardiff between 1919 and 1951, examines their attitudes towards Britain's ‘half‐caste’ population.     

Mortality,past and future

The study of mortality in previous centuries and of the trends in recent decades helps to elucidate some present-day medical problems and to contribute to their solution. The author considers, from a historical and socio-economic point of view, the factors which, during the last 200 years, have influenced the trends of mortality. This analysis indicates the lines along which present research, aimed at reducing mortality and extending expectation of life, should be directed.

Infancy (0–1 year): In backward countries, the whole of infancy is a period of high mortality. In progressive countries, on the other hand, the main reproductive wastage is in the ‘perinatal’ period, that is to say, covering stillbirths and deaths during the first week of life. For example, even in New Zealand, the death risk per day is more than eighty times as high during the first week of life than in the following 358 days.

Historical studies and social class comparisons suggest that further reduction of perinatal mortality is likely to depend on socio-economic, housing and cultural factors rather than on improvements in obstetric skill. Evidence cited by the author indicates that a crucial factor may be to provide expectant mothers with adequate rest during the weeks immediately prior to delivery. In general, research into mortality in infancy is too much bounded by a purely medical point of view whereas a socio-medical approach is needed.

Childhood (1–14 years): There has been an immense reduction in childhood mortality during the last 200 years. Less than 200 years ago the mortality among children aged 1–4 and 5–9 years was thirty-three times, and among those aged 10–14 years twelve times, that of the present day. Future reduction of mortality among children will be primarily a function of social factors and trends.

Adolescence and maturity (15–49 years): One of the outstanding trends of the last 200 years has been a relative increase in tuberculosis mortality among those aged 15–49 years, whereas among children tuberculosis has become relatively less important

as a cause of death. Recently, however, there has been a decline in the relative importance of tuberculosis as a cause of death among the adolescent and mature and, among New York males, it now takes second place to the cardiovascular

diseases. The total mortality of people in this age group has fallen, since the sixteenth century, by 77% for men and 81% for women. No spectacular discoveries are needed to reduce the mortality of this group by a further third; in doing this, control of environment will be the important factor.

Later maturity and old age (50 years and over): In the four centuries since the Renaissance the mortality of people over 50 years of age has been reduced by half. Among the factors contributing to this reduction is a fall in mortality due to tuberculosis. But even cancer, which is popularly supposed to have increased, used to be more common in the eighteenth century than it is now and to appear at an earlier. age. Moreover, there has been a change in the organs most commonly affected. The distribution of the greater proportion of cancer in a given population is a function of living conditions in the broadest sense of the term. Studies of groups exposed to carcinorelevant factors suggest that a high incidence of cancer in one organ is associated with a low incidence in other organs. But on many other causes of death at the older ages far more research is required, especially on the cardio-vascular-renal complex, and on the degenerative joint and bone diseases.     

A Twin Study of Adult Gambling Behavior

A twin study explored the possible genetic influences on gambling behavior. Male monozygotic (MZ) twins (n = 42) revealed significantly greater similarity on gambling frequency associated with high-action games than male dizygotic (DZ) twins (n = 50). The heritability estimates for involvement in these types of games among males were moderate and significant. All MZ versus DZ comparisons among males for low-action games were nonsignificant, as were MZ versus DZ comparisons among females (n = 63) for both types of games. The findings suggest that genetic influences may be important in the origins of certain types of gambling by men.     

Primary care for young African American men

Young African American men in the inner city have higher rates of mortality and morbidity from potentially preventable causes than other American men of the same age. They suffer disproportionately high rates of preventable illness from violence, sexually transmitted diseases, and HIV infection. These young men present with problems related to sexual concerns, mental health issues, substance abuse, and violence. They also report substantial risk-taking behaviors, including unprotected sex, substance use, and weapon carrying, as well as exposure to violence. Access to and use of preventive primary care services has been limited for these patients in the past because of financial barriers and competing social issues. Racism and historical oppression have created barriers of mistrust for young men of color. Factors that contribute to their adverse health status, as well as ways to address these problems, are discussed.     

ESTIMATION OF THE CONDITIONAL PROBABILITY OF TUBERCULOSIS GIVEN THE RESPONSE OF A MANTOUX TEST

For the planning of community tuberculosis, prophylaxis one must know the prevalence of tuberculosis (TB) infection as a function of response to the Mantoux intradermal tuberculin test; the standard test for indicating Mycobacterium TB infection. The skin induration size used to select individuals for prophylaxis must be chosen carefully, in view of the costs associated with carrying out and supervising such prophylaxis. The Mantoux test was used to obtain measurements on adolescents in metropolitan Victoria and on a small sample of adolescents with clinical TB. These data are employed to obtain estimates and to construct upper confidence bounds for the conditional probability of TB infection, given the level of Mantoux response. Two conservative methods are presented; one is ‘nonparametric’, the other ‘semiparametric’. The analyses indicate that for responses up to and including 13 mm, the probability of TB infection is less than.07 with ninety-five percent confidence.     

Information,disinformation, and union success in certification and decertification elections

In certification elections, workers consider the purchase of union services whose quality is, ex ante, unobservable. Voters must rely on available signals or indices in forming their expectations. Union members are able to reevaluate their initial purchase decision as more accurate information is obtained through experience. Therefore, participants in decertification elections rely less on sources of imperfect information. Using NLRB data over the period 1966 to 1990, we find evidence consistent with information-related distinctions between the certification and decertification decisions. Our study provides a useful framework for understanding the observed differences between these two types of elections.
