Sex role effects on female response to illness

This study of sex differentials in health behavior and health service choice among the Korean rural population is based on 1421 individuals aged 14 and over who received medical care at hospitals or clinics, pharmacies, a government health center, or through Chinese medical practices. Logistic regression is used to explore the relationship between the dichotomous variable, the log of the odds of the probability of using formal health care services, and the independent variables (sex, age, education, marital status, perceived health status, perceived medical care need, illness days in bed, limited activity days, total sick days, date of illness). A profile of rural Korea shows for all ages fewer adult females than males, but more females 65 years who have been previously married, which suggests higher male mortality rates in the middle ages. Health service usage is higher among the elderly. Higher level of education is associated with greater use of formal medical service. The results of binomial and multinomial analysis indicate that women receive less medical care from the formal system in spite of complaints and restricted activity, and least of all from health centers. It is suggested that personnel at health centers may reduce the desire for care because of incompatible social backgrounds (young single males who are inexperienced, city bred, and completing required service). A woman must carefully choose from the formal system and may more easily use the informal system of pharmacies and Chinese medicine practice. The responses to self rated health showed many differences; males report better health than females and older people consider themselves more unhealthy than young or adult groups. Those with lower educational attainment also consider themselves unhealthy, and indicate greater need for health services. Females and older age groups also stated their need for professional medical care for an illness within 15 days prior to the survey. The mean number of bed days followed a similar pattern as the perceived need and self rated health. However, women had a lower volume of bed days than men in contrast to typical Western trends. Females reported more restricted days of activity. The old age group had the same restricted days but more bed days than the adult group. Reported chronic diseases were greater for lower socioeconomic groups.     

Differentials in Adult Mortality and Activity Limitation by Years of Education in the United States at the End of the 1990s

This study examines mortality differentials and health disparities between educational groups within the 1998 adult population (ages 25 and older) in the United States. Mortality differentials are measured using average life expectancy and health disparities by expected years without activity limitation. The results indicate that for both sexes, higher education is associated with higher life expectancy. Those with higher levels of education also have higher life expectancy without activity limitation. Adults with higher education can also expect to enjoy a greater percentage of their expected lives free of any form of activity limitation. At each level of education, adult females have a higher level of activity limitation compared to adult males. At the same level of education, adult females expect to enjoy smaller percentages of their remaining lives free of activity limitation compared to adult males of the same age.     

Gender-related Effect of Cultural Participation in Psychological Well-being: Indications from the Well-being Project in the Municipality of Milan

Gender differences have been observed in the way males and females process cognitive stimuli coming from exposure to works of art and participation in leisure activities. For this reason, we designed a project to assess this issue, with a cross-sectional study in Milan, on a sample of the population consisting in 1,000 inhabitants. Our objective was to assess how cultural participation affects subjective well-being, measured with the Psychological General Well-being Scale, which gives a global index of psychological well-being ranging from 0 (lowest level of well-being) to 110 (highest level of well-being). The survey was conducted with the assistance of Doxa, an Italian pollster company, through telephone interviews, according to the Computer Aided Telephone Interview system. A significant statistical difference in variable distribution between the two genders was found for civil status (more males resulted as being single and more women widowed), income (higher income in males), cultural participation (higher in males) and psychological well-being (higher in males). As expected, state of health has the maximum impact on the level of psychological well-being. The increase in the number of concomitant diseases is in fact linearly associated with a progressive increase in psychological distress with average scores of around 60 (very low level of well-being), in the presence of 5 or more concomitant diseases, in both males and females. The impact profile of nine major determinants on subjective well-being resulted to be clearly different in the two genders. Health status dominates in both, but its impact is higher in females than in males. The obtained results remained substantially unchanged also when the two gender groups were matched according to civil status and income level distribution. Leisure activities play an important role in females (second place after health status), while in males they result as being less important (fourth place after health status, civil status and occupation). Education is quite important for females (third place), while it is given the least importance in males. This different profile probably reflects different social and environmental influences on the two genders. The social and psychological implications of these findings are discussed.     

Male mating behavior in relation to spermatophore transfer in the white cabbage butterfly

The lifetime mating frequency of female butterflies is believed tobe dependent on the reproductive status of the males which they have mated. This report assesses those status usingPieris rapae L. Multiple mating females mated males with a short time interval after the last mating or males with many mating records. Such males, like small ones, produced small spermatophores during copulation, which may have resulted in high mating frequency of those females. The males with short time interval after the last mating or those with many mating records also showed a long mating duration. Alternative interpretations of the adaptive significance of this behavior for males are discussed.     

The Contribution of Drug Overdose to Educational Gradients in Life Expectancy in the United States, 1992–2011

Since the mid-1990s, the United States has witnessed a dramatic rise in drug overdose mortality. Educational gradients in life expectancy widened over the same period, and drug overdose likely plays a role in this widening, particularly for non-Hispanic whites. The contemporary drug epidemic is distinctive in terms of its scope, the nature of the substances involved, and its geographic patterning, which influence how it impacts different education groups. I use vital statistics and National Health Interview Survey data to examine the contribution of drug overdose to educational gradients in life expectancy from 1992–2011. I find that over this period, years of life lost due to drug overdose increased for all education groups and for both males and females. The contribution of drug overdose to educational gradients in life expectancy has increased over time and is greater for non-Hispanic whites than for the population as a whole. Drug overdose accounts for a sizable proportion of the increases in educational gradients in life expectancy, particularly at the prime adult ages (ages 30–60), where it accounts for 25 % to 100 % of the widening in educational gradients between 1992 and 2011. Drug overdose mortality has increased more rapidly for females than for males, leading to a gender convergence. These findings shed light on the processes driving recent changes in educational gradients in life expectancy and suggest that effective measures to address the drug overdose epidemic should take into account its differential burden across education groups.     

Host-size-dependent sex ratio in a parasitoid wasp

Charnov's host-size model explains parasitoid host-size-dependent sex ratio as an adaptive consequence when there is a differential effect of host size on the offspring fitness of parasitoid males versus females. This article tests the predictions and the assumptions of the host-size model. The parasitoid wasp Pimpla nipponica Uchida (Hymenoptera: Ichneumonidae) laid more female eggs in larger or fresher host pupae when choice among hosts of different sizes or ages was allowed. Then, whether an asymmetrical effect of host size and age on the fitness of females versus males existed in P. nipponica was examined. Larger or fresher host pupae yielded larger wasps. Larger females lived longer, whereas male size did not influence male longevity. Large males mated successfully with relatively large females but failed with small females, whereas small males could mate successfully either with small or with large females. Thus, small-male advantages were found, and this held true even under male–male competition. Ovariole and egg numbers at any one time did not differ among females of different sizes. Larger females attained higher oviposition success and spent less time and energy for oviposition in hosts. Larger females produced more eggs from a single host meal. Taken together, females gained more, and males lost more, by being large. Host size and age thus asymmetrically affected the fitness of offspring males versus females through the relationships between host size or hast age and wasp size, which means the basic assumption of the host-size model was satisfied. Therefore, sex ratio control by P. nipponica in response to host size and age is adaptive. Received: November 13, 1998 / Accepted: January 18, 1999     

Gender differences in health promotion behaviors and quality of life among community-dwelling elderly

The differences of basic attributes, health promotion behaviors, and quality of life between elderly males and females in Taiwan were compared. Several scales were used to examine the gender differences and the factors associated with quality of life. Regression analysis revealed that gender, education level, depression level, and healthy diet were key factors influencing the overall quality of life. The education level of females was lower, and their depression level was higher; however, females had healthier diets. With regards to their satisfaction in the quality of life, elderly males scored higher than females in both the physical and psychological domains.     

Long-term effects of international migration: Lessons from Israel

The paper shows that characteristics of immigrants at the time of immigration affect both long-term occupational achievements and income at the end of the labor force career, after age 59. Data representing 174,000 Jewish males 60 and older from a 1985 survey by the Israeli Central Bureau of Statistics are analyzed to show how the timing of immigration, the number of years in the country, age at immigration, country of origin, and educational resources at time of immigration are related to years in the labor force in the host country, occupational achievement, pension entitlement and income after age 59. Both direct and indirect effects are analyzed. The results show the importance of immigration characteristics on long-term socioeconomic adjustment, and the necessity of considering social status over the life course as an indicator of long-term immigrant adjustment. Decomposition of the effect of country of origin pinpoints what characteristics at time of immigration influence social status differences in ethnic groups at older ages. The discussion includes a number of methodological implications for future studies in immigration.Abbreviations AA Asian-African - CBS Israeli Central Bureau of Statistics - EA European-American This article is based on a paper presented at the annual meeting of the Society for the Advancement of Socio-Economics, New York, March 1993.

Does Female Disadvantage Mean Lower Access to Food?

The literature on gender differentials in nutrition demonstrates that the calorie intake of females is generally as adequate as that of males at all ages. Female disadvantage in micronutrient intake is, however, frequent. Pregnant and lactating women are disadvantaged relative to both men and other women. In South Asia there is evidence that boys are advantaged over girls in food intake at some ages, but the evidence for male advantage in access to health care is far stronger. The authors argue that nutrition interventions are best targeted when the incidence of female disadvantage is better understood and, similarly, that interventions to improve women's status should be focused on objectives other than calorie intake in most communities. However, standards for measuring adequacy incorporate norms for female body size and physical activity that may uncritically accept the notion that females are more physically passive. Maintaining adequacy by these standards could perpetuate low levels of female functioning.     

Occupational careers and mortality of elderly men

This article presents findings from an analysis of occupational differentials in mortality among a cohort of males aged 55 years and older in the United States for the period 1966-1983. Using the National Longitudinal Survey of Mature Men, we construct event histories for 3,080 respondents who reach the exact age of 55. The dynamics that characterize socioeconomic differentials in mortality are analyzed by evaluating the differential effects of occupation over the career cycle. Maximum likelihood estimates of hazard-model parameters show that the mortality of current or last occupation differs substantially from that of longest occupation, controlling for education, income, health status, and other sociodemographic factors. In particular, the rate of mortality is reduced by the substantive complexity of the longest occupation while social skills and physical and environmental demands of the latest occupation lower mortality.     

The influence of psychological and situational factors on the contraceptive behavior of single men: A review of the literature

The study of contraceptive behavior has focused on women with relatively few studies examining the psychological and situational factors that influence male contraceptive behavior. A review of empirical studies indicates the importance of the personality variable of sexual anxiety and the cognitive variables of attitudes toward contraception and sex roles in influencing the contraceptive behavior of single males. However, the situational variable of having an established sexual relationship is the best predictor of whether contraception is used. Although the contributions of attitude and utility theorists have been of substantial assistance in understanding the contraceptive behavior of married couples, the affect-reinforcement theory appears to be more applicable to contraceptive behavior in general. An analysis of the socialization of males and females in terms of utility theory also helps explain the relative failure of adolescent couples in contraception.This research was funded by team grants from Health and Welfare, Family Planning Division, Canada and from Ministère des Affaires Sociales, Quebec. In addition, the second author was supported by a Bourse de I'Enseignement Superieur from the Quebec Government.

A Preliminary Examination of Covitality as Integrated Well-Being in College Students

The emergence of positive psychology has generated increased interest about the correlates of positive psychological functioning. Researchers have identified and studied various positive psychological constructs (e.g., hope, optimism, self-efficacy, gratitude, and life satisfaction) and found them to covary and to be positively associated with optimal human functioning and negatively associated with mental illness. This study of 528 college students examined the co-occurrence of selected positive psychological traits and explored their relations with a proposed second-order latent construct called covitality and with psychological well-being. Structural equation modeling examined each first-order positive psychology construct related to the second-order concept of covitality. Findings supported the second-order latent factor model of covitality, which was also significantly related to indicators of psychological well-being. Implications for theory development related to understanding positive human resources and applications within the context of college student populations are discussed.     

从再婚人口的性别差异看城市女性的再婚困境——以北京为例

随着我国婚姻解体数量的增多，再婚也日益普遍。基于北京市人日抽样调查数据和婚姻登记数据的计算结果表明，北京近年来失婚女性的再婚率只有男性的40％左右。通过对再婚人口的婚次、年龄、教育程度和户籍等方面的特征及其匹配特点的分析，可以看到女性在再婚过程中相对男性处于明显的弱势地位，而“男高女低”的婚配模式则是造成城市女性再婚困境的主要原因。     

Occupational mobility and fertility in metropolitan Latin America

The relation between career mobility and reproductive behavior is examined for five cities of developing Latin American nations: Bogota, Columbia; San Jose, Costa Rica; Mexico City, Mexico; Panama City, Panama; and Caracas, Venezuela. The data are obtained from fertility surveys conducted between September, 1963, and August, 1964, in the above-named cities under the auspices of the Centro Latinoamericano de Demografía (CELADE), and the analysis is based on information from 600–800 women per city who have been married only once and married ten years or more. Career mobility is defined as an occupational change of the husband between the date of marriage and 1963–1964, based on the Hall-Jones occupational scale. Reproductive behavior is operationalized as the number of live births. The conclusion of the multiple classification analysis is that the process of career mobility in four out of five Latin American samples is not a significant factor in explaining differential reproductive behavior. These results are compatible with a variety of North American studies which stress that variation heretofore ascribed to the process of mobility is an additive composite of past and present status effects. These findings are discussed; a theoretical and methodological critique of mobility-fertility research is presented.     

Reproductive behavior of the Japanese treefrog,Rhacophorus arboreus (Anura: Rhacophoridae)

Reproductive behavior of the foam-nesting treefrog,Rhacophorus arboreus, is described. Oviposition was made either by an amplectant pair (a female, and an amplectant male) alone or by an amplectant pair and other males (joiners). The snout-vent length of males and females was negatively correlated with the date of the first appearance in the pond. The period of staying in the pond in males was longer than that in females. Physical body contacts of other males, and encounter calls by ampletant males were frequently observed before oviposition with joiners. Snout-vent length of the female and an amplectant male were positively correlated. Encounter calls by amplectant males were likely to precede movement of females. There was no difference of snout-vent length between amplectant males and joiners. Females moved the hindlimbs more frequently than males during oviposition. Amplectant males made encounter cells more frequently in oviposition with joiners, than oviposition without joiners. The patterns of transitions between acts of females and amplectant males were similar between oviposition with and without joiners. Females more frequently responded to amplectant males than joiners. Both the duration of a bout of the movements of hindlimbs of females and the interval between the bouts were longer in oviposition without joiners than that with joiners. The number of the movements per bout in oviposition without joiners was smaller than that with joiners. Encounter calls by amplectant males during oviposition tended to precede the hindlimb movements of females.     

Impact of the 1999 East Marmara Earthquake in Turkey

This paper studies responses to the 1999 Marmara Earthquake (Turkey) in which 18,000 people died, 50,000 people were injured, there were 5,000 building collapses and 340,000 damaged buildings, 14,513 businesses closed, 150,000 people became unemployed, and 129,338 were forced to live in prefabricated houses. This research is based on a survey comprising 500 interviews carried out a year after the earthquake. Responsible behavior as the dependent variable is statistically tested with several socio-demographic and attitude variables. The findings indicate social solidarity, knowledge, basic needs, desire for change and psychological status of the disaster survivors were all adversely affected. It was observed that education, employment, social security, knowledge and fatalism have varying impacts on responsible behavior related to preparedness for future earthquakes.     

Intergenerational Profiles of Socioeconomic (Dis)advantage and Obesity During the Transition to Adulthood

Investigations of socioeconomic status (SES) and health during the transition to adulthood in the United States are complicated by the later and more varied transitions in residence, employment, schooling, and social roles compared with previous generations. Parental SES is an important influence during adolescence but cannot sufficiently capture the SES of the independent young adult. Typical, single SES indicators based on income or education likely misclassify the SES of young adults who have not yet completed their education or other training, or who have entered the labor force early with ultimately lower status attainment. We use a latent class analysis (LCA) framework to characterize five intergenerational SES groups, combining multidimensional SES information from two time points—that is, adolescent (parental) and young adult (self) SES data. Associations of these groups with obesity, a high-risk health outcome in young adults, revealed nuanced relationships not seen using traditional intergenerational SES measures. In males, for example, a middle-class upbringing in adolescence and continued material advantage into adulthood was associated with nearly as high obesity as a working poor upbringing and early, detrimental transitions. This intergenerational typology of early SES exposure facilitates understanding of SES and health during young adulthood.     

Child Mortality in Beirut: Six Indirect Estimates Based on Data Collected at the Time of a Birth

Six indirect techniques for estimating child mortality were applied to information on survival status of all children ever born, provided by a sample of 1,252 women delivered at the Maternity Unit of the American University of Beirut Hospital. The results were compared, using as a reference the estimate derived from partial birth histories (ages of surviving children, ages at death of children who have died). Their dispersion is minimal for the probability of dying between birth and fifth birthday, estimated at 48 per thousand. For each mother, the ratio of the observed number of children who have died, to that expected given the lengths of exposure of the children to the risk of mortality, was used as a dependent variable in a multiple regression analysis. Educational level of mothers had a significant effect, but not occupational status of father, religion or consanguinuity.     

Age cohort differences in the developmental milestones of gay men

As the social context in which gay men live changes due to greater visibility, greater acceptance, and easier access to gay subculture, gay males may self-identify and take part in gay social activities at earlier ages than in the past. This study examined whether developmental milestones associated with sexual orientation for gay men have changed over the past several decades. A large and diverse sample of 2,402 gay men who responded to a 1994 survey published in a national magazine provided retrospective information on the age at which they reached individual psychological, social, and sexual behavior developmental milestones. We found evidence that individual psychological and sexual behavior milestones (e.g., awareness of attraction to males, having an orgasm with other male) are slowly moving toward earlier chronological ages (by 1 year of age every 8-25 years, p < 0.05), whereas social milestones (e.g., coming out) are moving more rapidly in a similar direction (by 1 year of age every 2-5 years, p < 0.001). The authors perform an innovative sensitivity test to demonstrate the persistence of the finding after correcting for the bias attributable to underrepresentation of those who have not yet self-identified as gay in such samples.
