Sensation seeking and men's face preferences

Findings from previous studies suggest that only men who are in good physical condition can afford to pursue high-risk activities and that men who engage in high-risk activities are considered particularly attractive by women. Here, we show that men's interest in high-sensation activities, a personality trait that is known to increase the likelihood of those individuals engaging in high-risk behaviors, is positively related to the strength of their preferences for femininity in women's faces (Studies 1–3) but is not related to the strength of their preferences for femininity in men's faces (Study 2). We discuss these findings as evidence for potentially adaptive condition-dependent mate preferences, whereby men who exhibit signals of high quality demonstrate particularly strong preferences for facial cues of reproductive and medical health in potential mates because they are more likely than lower-quality men to succeed in acquiring such partners.     

A biosocial model of medication use among older women and men in Ismailia, Egypt

In Western industrialized countries, women report using health services, and certain medications, more often than do men. Often, analyses are based on data that exclude objective measures of morbidity and that come from cross-sectional surveys, which precludes the use of socioeconomic covariates that are endogenous to seeking care. Here, differences in objective cognitive and physical function, as well as differences in reporting on illness, propensity to seek care, and socioeconomic resources are expected to account for differences in care-seeking behaviour among women and men. This model is applied to the question of medication use in Ismailia, Egypt, using two waves of survey data and in-home tests of physical function from 896 adults aged 50 years and older. The results show that women use "modern" medications more often than do men, and that differences between women and men in reported morbidity and disability, observed cognitive and physical function, and economic resources account for women's greater use of medication. The findings underline a need for biosocial models to understand differences in women's and men's care-seeking behaviour in later life.     

Are husbands a barrier to women's family planning use? The case of Morocco

Little is known about men's role in the adoption of family planning. Recent studies suggest that men may be a barrier to women's use of family planning. However, it is not clear whether husbands represent a true or a perceived barrier. Using the 1992 Morocco Demographic and Health Survey data, this study examines (1) whether women and men report concordant fertility desires, discussions, and contraceptive use; (2) the accuracy of women's perceptions of their husbands' fertility desires; and (3) whether husbands are a barrier to women's family planning use. The results demonstrate that, controlling for women's own fertility desires, husbands' true fertility desires are associated with family planning use. Likewise, women who perceive their husbands to want fewer children than they want are more likely to use family planning. Future fertility and family planning programs need to include men to reduce their role as both perceived and true barriers to family planning use.     

Reading men's faces: women's mate attractiveness judgments track men's testosterone and interest in infants

This study investigated whether women track possible cues of paternal and genetic quality in men's faces and then map perception of those cues onto mate attractiveness judgments. Men's testosterone concentrations served as a proxy for genetic quality given evidence that this hormone signals immunocompetence, and men's scores on an interest in infants test were chosen as prima facie markers of paternal quality. Women's perceptions of facial photographs of these men were in fact sensitive to these two variables: men's scores on the interest in infants test significantly predicted women's ratings of the photos for how much the men like children, and men's testosterone concentrations significantly predicted women's ratings of the men's faces for masculinity. Furthermore, men's actual and perceived affinity for children predicted women's long-term mate attractiveness judgments, while men's testosterone and perceived masculinity predicted women's short-term mate attractiveness judgments. These results suggest that women can detect facial cues of men's hormone concentrations and affinity for children, and that women use perception of these cues to form mate attractiveness judgments.     

Social transmission of face preferences among humans

Previous studies demonstrating mate choice copying effects among females in non-human species have led many researchers to propose that social transmission of mate preferences may influence sexual selection for male traits. Although it has been suggested that social transmission may also influence mate preferences in humans, there is little empirical support for such effects. Here, we show that observing other women with smiling (i.e. positive) expressions looking at male faces increased women's preferences for those men to a greater extent than did observing women with neutral (i.e. relatively negative) expressions looking at male faces. By contrast, the reverse was true for male participants (i.e. observing women with neutral expressions looking at male faces increased male participant's preferences for those men to a greater extent than did observing women smiling at male faces). This latter finding suggests that within-sex competition promotes negative attitudes among men towards other men who are the target of positive social interest from women. Our findings demonstrate that social transmission of face preferences influences judgments of men's attractiveness, potentially demonstrating a mechanism for social transmission of mate preferences.     

Integrating cues of social interest and voice pitch in men's preferences for women's voices

Most previous studies of vocal attractiveness have focused on preferences for physical characteristics of voices such as pitch. Here we examine the content of vocalizations in interaction with such physical traits, finding that vocal cues of social interest modulate the strength of men's preferences for raised pitch in women's voices. Men showed stronger preferences for raised pitch when judging the voices of women who appeared interested in the listener than when judging the voices of women who appeared relatively disinterested in the listener. These findings show that voice preferences are not determined solely by physical properties of voices and that men integrate information about voice pitch and the degree of social interest expressed by women when forming voice preferences. Women's preferences for raised pitch in women's voices were not modulated by cues of social interest, suggesting that the integration of cues of social interest and voice pitch when men judge the attractiveness of women's voices may reflect adaptations that promote efficient allocation of men's mating effort.     

Authoritative knowledge and single women's unintentional pregnancies,abortions, adoption,and single motherhood: social stigma and structural violence

This article explores the sources of authoritative knowledge that shaped single, white, middle-class women's unintentional pregnancies and child-bearing decisions throughout five reproductive eras. Women who terminated a pregnancy were most influenced by their own personal needs and circumstances. birth mothers' decisions were based on external sources of knowledge, such as their mothers, social workers, and social pressures. In contrast, single mothers based their decision on instincts and their religious or moral beliefs. Reproductive policies further constrained and significantly shaped women's experiences. The social stigma associated with these forms of stratified maternity suggests that categorizing pregnant women by their marital status, or births as out-of-wedlock, reproduces the structural violence implicit to normative models of female sexuality and maternity. This mixed-method study included focus groups to determine the kinds of knowledge women considered authoritative, a mailed survey to quantify these identified sources, and one-on-one interviews to explore outcomes in depth.     

Control tactics and partner violence in heterosexual relationships

This study investigated sex-specific predictors of violent and nonviolent mate guarding used by men (n=399) and women (n=951) in heterosexual relationships, using both self-reports and reports on partners. We found, contrary to some previous evolutionary assumptions, that men and women showed similar degrees of controlling behavior, and that this predicted physical aggression to partners in both sexes. We also predicted from evolutionarily based studies that men's and women's control and aggression would vary as a function of female fecundity and mate value (relative to peer group and to partner). Fecundity was associated with men's and women's controlling behavior, but not their physical aggression: relationships where the woman was fecund showed higher rates of control. According to partners' reports, men and women who had lower mate values showed more controlling behavior and (to a lesser extent) more physical aggression. There was no support for the prediction that higher mate-value partners would be guarded more than lower mate-value ones. The following limitations are discussed: the sample and method of data collection, and the lack of information on the women's hormonal status.     

Patterns of sexual behaviour and reported symptoms of STI/RTIs among young people in Croatia--implications for interventions' planning

This paper describes some of the results of the first national-level survey on sexual behaviour and the distribution of risks to sexually transmitted infections (STIs), including human immunodeficiency virus infection (HIV), among youth in Croatia, and the nature and the extent of their vulnerability to these adverse health outcomes. The study was a cross-sectional, probability-based household survey conducted in 2005, and included 1093 respondents aged 18-24. This paper aims to describe the findings related to the knowledge of HIV transmission, key behavioural outcomes relevant for potential transmission of HIV and STIs, and correlates of genital discharge in young men and young women. More than 80% of young people know that the correct use of condoms protects against HIV and that HIV can be transmitted by someone who looks healthy. Fifty-nine percent of young men and 52.4% of young women reported using condoms during the first sexual intercourse, and 59.3% of men and 46.1% of women used condoms during the last sexual intercourse with a casual partner. This points to the gap between knowledge of condom use and the actual use of condoms as a high proportion of risky sexual contact remain unprotected. Having sexual intercourse frequently or regularly while consuming alcohol was reported by 19.2% of men and 7.6% of women. Much lower proportion are using drugs frequently or regularly during sexual intercourse (3.7% of men and 2.1% of women). Among those sexually experienced, 11.8% of men and 44.1% of women reported ever having a genital discharge. Higher presence of genital discharge in women is suggestive of reproductive tract infections that are not necessarily sexually transmitted. In the multivariate analysis, the lack of knowledge of whether chlamydial infections is an STI and having more than five partners in life were correlates of genital discharge in men, while in women the correlates included having more than five partners in life and not using condoms during the first sexual intercourse. Higher burden of STI-related symptoms was found among men who have men as sexual partners, those who paid for sex, and those with concurrent partnerships. These findings point out to the immediate need to strengthen sexual health education among young people and to the necessity for further development of other broad-based interventions to prevent adverse sexual health outcomes among both men and women, as well as those targeted towards more vulnerable subgroups.     

Understanding users' perspectives of barriers to maternal health care use in Maharashtra, India.

This paper uses data collected using in-depth, semi-structured interviews to examine utilization of maternal health care services among two rural and urban populations of Pune and Mumbai in Maharashtra, India. The study aims to identify key social, economic and cultural factors influencing women's decisions to use maternal health care and the places used for child delivery, whilst considering the accessibility of facilities available in the local area. Socioeconomic status was not found to be a barrier to service use when women perceived the benefits of the service to outweigh the cost, and when the service was within reasonable distance of the respondent's place of residence. A large number of women perceived private services to be superior to those provided by the government, although cost often meant they were unable to use them. The provision of services did not ensure that women used them; they had to first perceive them to be beneficial to their health and that of their unborn child. Respondents identified the poor quality of services offered at government institutions to be a motivating factor for delivering at home. Thus further investigation is needed into the quality of services provided by government facilities in the area. A number of respondents who had received antenatal care went on to deliver in the home environment without a trained birth attendant. Further research is needed to establish the types of care provided during an antenatal consultation to establish the feasibility of using these visits to encourage women, particularly those with high-risk pregnancies, to be linked to a trained attendant for delivery.     

Walking attenuates the relationships of high-meat, low-fruit dietary intake to total and regional adiposity in men and women

Vigorous physical activity (running) has been shown to attenuate the association between diet and body weight. Walking is the most popular physical activity, but is a moderate-intensity physical activity because it requires less than sixfold the energy expenditure of sitting at rest. We therefore examined whether reported distance walked per week affected the relationship of diet to BMI and circumferences of the waist, hip, and chest in 30,014 female and 7,133 male participants of the National Walkers' Health Study. Reported meat and fruit intakes served as indicators of high-risk diets for weight gain. The analyses showed that higher meat and lower fruit intake were significantly and consistently associated with greater BMI and waist circumference at all activity levels. Longer usual walking distance significantly attenuated the concordant relationships of diet with women's BMIs (P < 10(-8)), men's BMIs (P = 0.04), and women's waist (P < 10(-6)), hip (P = 0.0001), and chest circumferences (P < 10(-5)). Compared to walkers who averaged <1.5 km/day, the association of diet with adiposity in subjects who walked ≥1.5 km/day was reduced 21% in women and 31% in men for BMI; 20% in women and 27% in men for waist circumference; 19% for women's hip circumference; and 26% for women's chest circumference. Thus we conclude that diets characterized by high-meat/low-fruit intake were significantly associated with greater BMI, and this association was attenuated by moderate physical activity. The weaker results in men than women probably related to the smaller sample size, and reduced statistical power of the men.     

Abortion-seeking behaviour among Nigerian women

This study used data from a community-based survey to examine women's experiences of abortion in Nigeria. Fourteen percent of respondents reported that they had ever tried to terminate a pregnancy, and 10% had obtained an abortion. The majority of women who sought an abortion did so early in the pregnancy. Forty-two percent of women who obtained an abortion used the services of a non-professional provider, a quarter experienced complications and 9% sought treatment for complications from their abortions. Roughly half of the women who obtained an abortion used a method other than D&C or MVA. The abortion prevalence and conditions under which women sought abortions varied by women's socio-demographic characteristics. Because abortion is illegal in Nigeria except to save the woman's life, many women take significant risks to terminate unwanted pregnancies. Reducing the incidence of unwanted pregnancy and unsafe abortion can significantly impact the reproductive health of women in Nigeria.     

Vagina dentata revisited: Gender and asymptomatic shedding of genital herpes

Medical research on genital herpes indicates that women shed herpes asymptomatically. This paper examines the medical understanding of asymptomatic shedding of herpes among women as partial knowledge, meaning biased and incomplete, based upon folk models of male and female sexual bodies and upon the structure of medical practice. The focus on women's sexual anatomy as dangerous to men and the lack of a medical specialty on male reproductive/sexual health results in blaming women for transmission of sexual diseases.     

Human mate guarding

Long-term committed mating is a fundamental strategy in the human repertoire. Successful enactment of this strategy requires solving two related adaptive problems--fending off potential mate poachers and preventing a mates from defecting. Mate guarding adaptations evolved to solve these persistent problems. Those who failed in mate guarding risked suffering substantial reproductive costs ranging from genetic cuckoldry to reputational damage to the entire loss of a mate. Because the precise nature of the adaptive problems confronted differed historically for the sexes, men and women evolved corresponding differences in the underlying psychology of mate guarding. Men's mate guarding, relative to that of women's, is strongly triggered as a consequence of being mated to young and physically attractive women, being confronted by interested rivals who have superior economic resources or prospects, and having a mate who displays signs of sexual involvement with a rival. Women's mate guarding, relative to that of men's, is triggered as a consequence of being mated to men high in income and status striving, rivals who are more physically attractive, and having a partner who shows signs of emotional involvement with another woman. Behavioral output of mate guarding adaptations range from vigilance to violence.     

The hide-and-seek game: men's perspectives on abortion and contraceptive use within marriage in a rural community in Zimbabwe

This paper is based on a study aimed at understanding the perceptions of men to induced abortion and contraceptive use within marriage in rural Zimbabwe. Two qualitative methods were combined. Men were found to view abortion not as a reproductive health problem for women. Instead, they described abortion as a sign of illicit sexual activity and contraceptive use as a strategy married women use to conceal their involvement in extramarital sexual activity. Men felt anxious and vulnerable for lack of control over women. In the absence of verbal communication on sexual matters, women and men resort to what are called here 'hide-and-seek' strategies, where women acquire and use contraceptives secretly while men search for evidence of such use. It is concluded that promoting women's sexual and reproductive health requires both short- and long-term strategies. The short-term strategy would entail providing women with reproductive technology they can use without risking violence. The long-term strategy would entail understanding men's concerns and the way these are manifested. In turn this requires the use of methodologies that encourage dialogue with research participants, in order to capture their deep meanings and experiences.     

Neural activation in the orbitofrontal cortex in response to male faces increases during the follicular phase

Women's sexual interest changes with hormonal fluctuations across the menstrual cycle. It is unclear how hormones modify women's sexual behavior and desire, but one possibility is that they alter women's positive appraisals of stimuli and thus their sexual interest. Using 3 T fMRI, we measured neural activation in women at two time points in their menstrual cycle (late follicular, luteal) while they evaluated photos of men presented as potential sexual partners. Participants were ten heterosexual women aged 23-28 none of who was using hormonal contraceptives or in a committed relationship. In an event-related design, the women were presented with as series of photos of male faces and asked questions to assess their degree of sexual interest in the men depicted. Results demonstrate an overall effect of menstrual cycle phase on neural activation. During their follicular versus luteal phase, women demonstrated increased activation in the right medial orbitofrontal cortex (OFC), suggesting increased positive appraisal. Activation in the OFC was positively correlated with women's estradiol to progesterone ratios. There were no areas that demonstrated increased activation during the luteal versus follicular phase. The observed increase in activation in the OFC during the follicular phase may reflect a hormonally mediated increase in appetitive motivation and may prime women towards increased sexual interest and behavior around ovulation.     

Body odor attractiveness as a cue of impending ovulation in women: evidence from a study using hormone-confirmed ovulation

Scent communication plays a central role in the mating behavior of many nonhuman mammals but has often been overlooked in the study of human mating. However, a growing body of evidence suggests that men may perceive women's high-fertility body scents (collected near ovulation) as more attractive than their low-fertility body scents. The present study provides a methodologically rigorous replication of this finding, while also examining several novel questions. Women collected samples of their natural body scent twice--once on a low-fertility day and once on a high-fertility day of the ovulatory cycle. Tests of luteinizing hormone confirmed that women experienced ovulation within two days of their high-fertility session. Men smelled each woman's high- and low-fertility scent samples and completed discrimination and preference tasks. At above-chance levels, men accurately discriminated between women's high- and low-fertility scent samples (61%) and chose women's high-fertility scent samples as more attractive than their low-fertility scent samples (56%). Men also rated each scent sample on sexiness, pleasantness, and intensity, and estimated the physical attractiveness of the woman who had provided the sample. Multilevel modeling revealed that, when high- and low-fertility scent samples were easier to discriminate from each other, high-fertility scent samples received even more favorable ratings compared with low-fertility scent samples. This study builds on a growing body of evidence indicating that men are attracted to cues of impending ovulation in women and raises the intriguing question of whether women's cycling hormones influence men's attraction and sexual approach behavior.     

Effect of mechanical loading on breathing patterns in women

First-breath ventilatory responses to graded inspiratory elastic and resistive loads were obtained from 80 women unfamiliar with respiratory experimentation. For each load 1) responses from different subjects ranged from a weak tidal volume defense coupled with an increased breathing frequency to a strong tidal volume defense coupled with a decreased frequency; 2) strong tidal volume defenders employed longer inspirations than did weak tidal volume defenders; and 3) individual respiratory frequency responses were mediated by changes in inspiratory and/or expiratory timing. Thus the group response was qualitatively the same as that reported for 80 men. Quantitatively, however, mean inspiratory airflow responses of women exceeded those of men by an amount attributable to women's higher intrinsic respiratory elastance. Tidal volume responses, on the other hand, did not differ significantly, suggesting that men and women produce different neural adjustments to loads. In support of this hypothesis, analysis of respiratory timing responses revealed that 1) men actively prolonged inspiration more than women during resistive loading; and 2) women actively shortened inspiration more than men during elastic loading. These findings indicate that the load-compensating behavior exhibited by men and women is similar but not identical.     

Prevalence of urinary incontinence.

The prevalence of urinary incontinence was investigated by determining the number of incontinent patients under the care of various health and social service agencies in two London boroughs and by a postal survey of the 22 430 people aged 5 years and over on the practice lists of 12 general practitioners in different parts of the country. The prevalence of incontinence known to the health and social service agencies was 0.2% in women and 0.1% in men aged 15-64 and 2.5% in women and 1.3% in men aged 65 and over. The postal survey, to which 89% of the people whose correct address was known replied, showed a prevalence of urinary incontinence of 8.5% in women and 1.6% in men aged 15-64 and 11.6% in women and 6.9% in men aged 65 and over. Nulliparous women had a lower prevalence than those who had had one, two, or three babies, but within the parity range of one to three there were no differences in prevalence. The prevalence was appreciably increased in women who had had four or more babies. Incontinence was moderate or severe in a fifth of those who reported it in the postal survey, of whom less than a third were receiving health or social services for the condition. Incontinence is a common symptom, and many unrecognised cases appear to exist. There may be considerable scope for improving its management.     

Defining women's health: a dozen messages from more than 150 ethnographies

Although the women's health research agenda has been largely defined by Western biomedicine and public health, anthropology has much to offer in terms of defining and understanding women's health from the perspective of women themselves. Through the in-depth qualitative tradition of ethnography, anthropologists have documented women's health concerns around the globe, producing a large and constantly expanding literature that is rich and provocative. This article summarizes a dozen major messages about women's health that emerge from the ethnographic literature, now consisting of more than 150 volumes. These volumes are listed in the article, and some primary examples are described as representative of anthropology's contribution to knowledge production in women's health.
