Environment and sex ratios among Alaska Natives: An historical perspective

Human-environment interactions can affect the sex ratios of resource-dependent societies in a variety of ways. Historical and contemporary data on Alaska Native populations illustrate such effects. Some eighteenth and early nineteenth century observers noted an excess of females, which they attributed to high mortality among hunters. Population counts in the later nineteenth century and well into the twentieth found instead an excess of men in many communities. Female infanticide was credited as the explanation: since family survival depended upon hunting success, males were more valued. Although infanticide explanations for the excess of males have been widely believed, available demographic data point to something else: higher adult female mortality. Finally, in the postwar years, the importance of mortality differentials seems to have faded- and also changed direction. Female outmigration from villages accounts for much of the gender imbalance among Native populations today. Natural-resource development, particularly North Slope oil, indirectly drives this migration. In Alaska's transcultural communities, the present gender imbalances raise issues of individual and cultural survival.     

India’s ‘Missing Women’ and Men’s Sexual Risk Behavior

Although scholars and policymakers have long been concerned with the ??missing women?? of India, little rigorous research has examined the consequences of India??s sex ratio imbalance for young men??s sexual risk behavior and reproductive health. We use data from the third wave of India??s 2005?C2006 National Family and Health Survey to examine the influence of the community female-to-male sex ratio at ages 10?C39 on men??s likelihood of marrying early in life, of engaging in premarital, multi-partnered, and commercial sex, and of contracting a sexually-transmitted disease. We estimate logistic regression models that control for respondents?? demographic and socioeconomic status and that adjust for the clustering of observations within communities. Net of the effects of other characteristics, the female-to-male sex ratio is positively and significantly associated with the likelihood that men marry prior to age 18 and inversely and significantly associated with the odds that men have had intercourse with a commercial sex worker. However, no significant net associations are observed between the sex ratio and the other outcomes. Education, wealth, religious affiliation, caste, and geographic region emerge as significant predictors of Indian men??s sexual risk behaviors.     

Skewed Sex Ratios and Criminal Victimization in India

Although substantial research has explored the causes of India’s excessively masculine population sex ratio, few studies have examined the consequences of this surplus of males. We merge individual-level data from the 2004–2005 India Human Development Survey with data from the 2001 India population census to examine the association between the district-level male-to-female sex ratio at ages 15 to 39 and self-reports of victimization by theft, breaking and entering, and assault. Multilevel logistic regression analyses reveal positive and statistically significant albeit substantively modest effects of the district-level sex ratio on all three victimization risks. We also find that higher male-to-female sex ratios are associated with the perception that young unmarried women in the local community are frequently harassed. Household-level indicators of family structure, socioeconomic status, and caste, as well as areal indicators of women’s empowerment and collective efficacy, also emerge as significant predictors of self-reported criminal victimization and the perceived harassment of young women. The implications of these findings for India’s growing sex ratio imbalance are discussed.     

Looking at Population Health Beyond “Male” and “Female”: Implications of Transgender Identity and Gender Nonconformity for Population Health

Looking beyond binary measurements of “male” or “female” can illuminate health inequality patterns that correspond to gender identity rather than biological sex. This study examines disparities in overall health among transgender men, transgender women, gender-nonconforming adults, and cisgender (nontransgender) men and women in the U.S. population. Behavioral Risk Factor Surveillance System (BRFSS) data from 32 U.S. states and territories between 2014 and 2016 yield an analytic sample that identifies 2,229 transgender and gender-nonconforming adults and 516,753 cisgender adults. Estimates from logistic regression models, using cisgender men as a reference group, show that gender-nonconforming respondents have significantly higher odds of reporting poor self-rated health than any other gender identity group. Transgender men also display higher odds of reporting poor health in some models, corresponding to their relative socioeconomic disadvantage. I find no apparent health disadvantage among transgender women and a persistent, if slight, disadvantage among cisgender women. Gender-nonconforming respondents’ predicted probabilities of reporting poor health remain nearly twice as high as those of cisgender men after adjustments for demographic, socioeconomic, and behavioral factors. Their persistent patterns of health-related disadvantage underscore the need for higher-quality data on gender-nonconforming respondents that account for sex assigned at birth.     

The obesity pay gap: gender,body size,and wage inequalities—a longitudinal study of Chinese adults, 1991–2011

Sociocultural values promoting Western body-type ideals have proliferated over the past 20 years. An important question is whether the same obesity wage penalties seen in the United States, such as wage reductions for obese individuals, are emerging in China as ideals of beauty change to reflect Western ones. We hypothesize that Westernisation will exacerbate the impact of body size on wages for years to come, particularly for urban non-manual workers whose workplaces call for extensive interpersonal relations with employers, colleagues, and customers. This study examines the economic outcomes for individuals aged 18–55, focusing on 6600 female and 8488 male participants in the longitudinal 1991–2011 China Health and Nutrition Survey. Linear fixed-effects regression models estimate the net effect of body mass index (BMI) on wages, as well as the marginal effect of BMI on wages, by survey year. All analyses control for demographic backgrounds and household fixed effects, and are stratified by gender. The results show that normal-weight women with non-manual jobs in 2011 made 2.79–2.95 times more than they had in 1991, while overweight women made 2.66–2.76 times more, and obese women made only 2.57–2.63 times more. The results also indicate that women with non-manual jobs have been subject to wage disparities since 2000. Specifically, the wage disparity for heavier women living in urban areas with non-manual jobs increased significantly after 2000, while current male obesity rates may have been propelled by social acceptance of larger body sizes among men, particularly for manual workers living in rural areas.     

Causes of Male Excess Mortality: Insights from Cloistered Populations

The degree to which biological factors contribute to the existence and the widening of mortality differences by sex remains unclear. To address this question, a mortality analysis for the years 1890 to 1995 was performed comparing mortality data on more than 11,000 Catholic nuns and monks in Bavarian communities living in very nearly identical behavioral and environmental conditions with life table data for the general German population. While the mortality differences between women and men in the general German population increased considerably after World War II, they remained almost constant among the members of Bavarian religious orders during the entire observation period, with slight advantages for nuns. Thus, the higher differences observable in the general population cannot be attributed to biological factors. The different trends in sex‐specific mortality between the general and the cloistered populations are caused exclusively by men in the general population who were unable to follow the trend in mortality reduction of women, nuns, and especially monks. Under the special environmental conditions of nuns and monks, biological factors appear to confer a maximum survival advantage for women of no more than one year in remaining life expectancy at young adult ages.     

HIV Risk Among Men Who Have Sex with Men Only (MSMO) and Men Who Have Sex with Men and Women (MSMW) in Baltimore

Men who have sex with men and women (MSMW) are at high risk for HIV. However, the majority of research on populations of men who have sex with men (MSM) combines MSMW and men who have sex with men only (MSMO) samples, which limits our understanding of HIV risk behaviors and factors associated with HIV risk among MSMW populations. We used the BESURE-MSM2, a venue-based cross-sectional study of HIV risk behaviors among MSM in Baltimore, MD, to examine HIV risk among MSMW. MSMW were less likely to report unprotected receptive anal intercourse than MSMO (6.8% vs. 19.6%, p = .0024). Among MSMW, 43.0% reported unprotected sex with a woman in the past year, but only 19.4% reported unprotected sex with both men and women, representing only 5.0% of the total MSM sample. In multivariate analyses, we found that among MSMW having unprotected sex with women in the past year, disclosing same sex behavior and having a main female partner were associated with unprotected anal intercourse with male partners. HIV prevention programs for MSMW are needed that address the complex partnerships of MSMW and the social contextual factors within which relationships and behaviors are embedded.     

The Gender of “Energy”: Language,Social Theory,and Cultural Change in Women’s Lands in the United States

Within women’s intentional communities, women use the phrase women’s energy to describe certain social interactions, a sense of community, and ideas about how gender is done or performed. For example, energy can express both difference in communication style between men and women and male dominance in social situations. During my fieldwork in these communities, I explored how this phrase suggests a reference to a precultural female body, but it is also sometimes used to explicitly reject biological reasons for gender difference. The term is easily understandable to a wide range of women from varying class backgrounds and encompasses both the unconscious side of social interactions and a possibility for future change.     

On the Far Eastern pattern of mortality

Since the early 1980s, it has been accepted widely that there is a Far Eastern pattern of mortality, a pattern characterized by excessively high death rates among older men relative to death rates among younger men and among women. It has been regarded as a unique regional mortality pattern, applying primarily to Far Eastern populations. A re-examination of the mortality data of some Far Eastern populations reveals that changes in both age patterns of and sex differentials in mortality have been widely observed. Further, mortality patterns similar to the so-called Far Eastern mortality model have been found in many other populations.

Historical changes in the household division of labor

A number of studies published in the 1970s asserted that the amount of time women spend doing housework shows no historical decline. This article draws on evidence from time-budget surveys—three from the United States (1965, 1975, and 1985) and three from the United Kingdom (1961, 1974, and 1984)—to investigate the evolution of housework time for men and women over the last three decades. Clearly much other than housework has changed over this period. More women have paid jobs, more men are unemployed, and families have gotten smaller on average. Even having controlled for such sociodemographic changes, we conclude that in the two countries, women in the 1980s do substantially less housework than those in equivalent circumstances in the 1960s, and that men do a little more than they did (although still much less than women). These changes correspond closely to developments in four other countries (Canada, Holland, Denmark, and Norway) for which historical time-budget evidence is available.     

Survey sheds new light on marriage and sexuality in the Philippines

The Young Adults Fertility and Sexuality Study (YAFS-II) was conducted in 1994 by interviewing 10,879 men and women aged 15-24 years in households on dating, marriage, and onset of sexual activity in the Philippines. In addition, screening data were collected on all households visited and on the 959 sampled local communities. Direct questions on premarital sex revealed that at least 52% of married women had sex before marriage. Among married respondents, 57% of men and 51% of women reported having had sex with their spouse before they were married. Only 3% of the women had additional premarital partners vs. 37% of the men. Questions on premarital sex and social patterns showed that about 20% of the single women and 28% of the single men had been in a serious relationship by the time they were 17. By age 20, 44% of the single women and 63% of the single men had been in a serious relationship, while the respective figures by age 24 were 60% and 68%. Altogether 24% of the women and 10% of the men described themselves as married. 34% of all women who either eloped or lived with their spouses had been married in church by the time of the survey, 23% had had civil ceremonies, and 41% designated their marital status as cohabitation. With regard to the risk of HIV/AIDS and other sexually transmitted diseases, 25% of the 24-year old men who never had a girlfriend reported sexual experience and 22% of those still single at age 24 reported that they had visited a commercial sex worker. Marital status was not the best basis for providing family planning services, and the provision of reproductive health services to young people living in consensual union would reduce accidental pregnancy.     

90年代以来中国夫妇年龄差变动趋势及其原因分析

夫妇年龄差的研究是人口学研究的一个重要领域。但目前的研究由于数据来源多样化,得出的结论不尽一致,关于年龄差的变化方向也没有形成定论。为此,本文利用我国三期妇女地位调查数据,对年龄差变动趋势进行分析。结果发现：我国同龄婚配的特点非常稳定,其比例维持在16％～17％之间。中国夫妇年龄差模式自90年代以来,发生了较大的变化,2010年中国传统的＂男高女低＂的婚配模式有所改变,这种＂男高女低＂婚姻明显下降,而＂女高男低＂婚姻明显升高,扣除同龄婚后二者平分秋色。其原因可能与我国出生性别比持续偏高和婚姻观念的转变等因素有关。     

The effect of the sex composition of jobs on starting wages in an organization: Findings from the NLSY

We show that individuals in a job with a higher percentage of females earn lower starting wages with an employing organization. This holds true with controls for individuals’ human capital, job demands for skill or difficult working conditions, and detailed industry. We use a measure of sex composition that applies to detailed jobs: cells in a three-digit census occupation by three-digit census industry matrix. We use pooled panel data from the 19791987 waves of the National Longitudinal Survey of Youth. The unit of analysis is the spell-the time in which a person worked for one organization. The dependent variable is the first wage in the spell. We use models with fixed-effects to control for unmeasured, unchanging individual characteristics; we also show results from OLS and weighted models for comparison. The negative effect on wages of the percentage female in one’s job is robust across procedures for black women, white women, and white men. For black men the sign is always negative but the coefficient is often nonsignificant.     

Socioeconomic marriage differentials in Australia and New Zealand

While marriage rates are relatively stable among better-educated men and women, they are rapidly declining among those with low educational attainment. This development has been recognized in the US as a new socioeconomic pattern of marriage. This article uses census data to show that socioeconomic marriage differentials are also increasing in Australia and New Zealand. These differentials have previously been noted independently of each other and of the international picture. In synthesizing the antipodean data, the article documents the new socioeconomic marriage pattern as an international phenomenon. This article further considers the extent to which the available explanations for the new marriage pattern fit the antipodean setting. In general, the factors identified as important in the North American setting are applicable to both Australia and New Zealand. In particular, the poor marriage prospects of men with low educational attainment appear to be common to these post-industrial economies with minimalist welfare states.     

女性就业竞争力与出生人口性别比的城乡差异分析

经验分析表明,相对于城镇而言,农村拥有更高的出生性别比,本文试图从经济学角度解释此现象。改革开放以来,中国城镇女性的就业竞争力有显著的提高,城镇中男女性别在就业与教育中的差异都存在收敛的现象。但在农村中,男性和女性无论是在就业竞争力还是在劳动收益上都存在很大的差距,而且,调查结果显示,无论是与农村男性还是与城镇女性相比农村女性的受教育机会都要少得多,这些因素共同决定了农村女性与城镇女性的就业竞争力差异,并影响了城乡出生性别比。     

Social capital and women's reduced vulnerability to HIV infection in rural Zimbabwe

Social capital—especially through its “network” dimension (high levels of participation in local community groups)—is thought to be an important determinant of health in many contexts. We investigate its effect on HIV prevention, using prospective data from a general population cohort in eastern Zimbabwe spanning a period of extensive behavior change (1998–2003). Almost half of the initially uninfected women interviewed were members of at least one community group. In an analysis of 88 communities, individuals with higher levels of community group participation had lower incidence of new HIV infections and more of them had adopted safer behaviors, although these effects were largely accounted for by differences in socio-demographic composition. Individual women in community groups had lower HIV incidence and more extensive behavior change, even after controlling for confounding factors. Community group membership was not associated with lower HIV incidence in men, possibly refecting a propensity among men to participate in groups that allow them to develop and demonstrate their masculine identities—often at the expense of their health. Support for women's community groups could be an effective HIV prevention strategy in countries with large-scale HIV epidemics.     

The female aging body: A systematic review of female perspectives on aging,health, and body image

While most body image research has focused on young female populations, evidence has shown that as few as 12% of older women are satisfied with their body size. Recent studies have also highlighted how anti-aging discourses are promoting unrealistic body norms, which have shown to contribute to poor body image and altered health behaviors. A systematic review of empirical studies focused on older women’s perspectives of health, body image, and the aging body is presented. Findings support that body image is a persistent, lifelong issue for women and should be considered when implementing healthy aging policies and practices.     

Social,behavioral, and biological factors,and sex differences in mortality

Few studies have examined whether sex differences in mortality are associated with different distributions of risk factors or result from the unique relationships between risk factors and mortality for men and women. We extend previous research by systematically testing a variety of factors, including health behaviors, social ties, socioeconomic status, and biological indicators of health. We employ the National Health and Nutritional Examination Survey III Linked Mortality File and use Cox proportional hazards models to examine sex differences in adult mortality in the United States. Our findings document that social and behavioral characteristics are key factors related to the sex gap in mortality. Once we control for women’s lower levels of marriage, poverty, and exercise, the sex gap in mortality widens; and once we control for women’s greater propensity to visit with friends and relatives, attend religious services, and abstain from smoking, the sex gap in mortality narrows. Biological factors—including indicators of inflammation and cardiovascular risk—also inform sex differences in mortality. Nevertheless, persistent sex differences in mortality remain: compared with women, men have 30% to 83% higher risks of death over the follow-up period, depending on the covariates included in the model. Although the prevalence ofriskfactors differs by sex, the impact of those riskfactors on mortality is similar for men and women.     

The educational attainment of young women: Role model effects of female high school faculty

To test for the presence of role model effects of female high school faculty and professional staff on young women in high school, we estimate several models of educational attainment for young women using data from the National Longitudinal Survey of Youth. Exposure to female high school faculty and professional staff has a positive impact on the educational attainment of young women. This result, combined with our finding that female faculty and professional staff have no significant impact on the educational attainment of young men, supports a female role model hypothesis.
