Body Size and Sexual Behavior in a Community-Based Sample of Women

ABSTRACT. Women's body size is closely related to their social and sexual experiences. Clinical research has found that women's lifetime sexual behaviors may vary based on body mass index (BMI). Objectives: This study examined the relationship between BMI and recent solo and partnered sexual repertoire in a community-based, non-clinical sample of women. Methods: Two hundred thirty-eight sexually active women completed an online survey measuring age, sexual relationship status, BMI, gender of sexual partners, and engagement in sexual behaviors in the previous 4 weeks. Logistic regression analyses were conducted to determine whether BMI predicted engagement in behaviors after controlling for age and sexual relationship variables. Results: Participant age ranged from 18 to 56 years (M = 30.4, SD = 7.8). Participants were predominantly in exclusive sexual relationships (62.9%, n = 146) with men (82.8%, n = 197). Mean BMI for the sample was 29.33 (SD = 9.28). Participation in self-masturbation, masturbating a partner, performing oral sex on a partner, receiving oral sex from a partner, and penile–vaginal intercourse were not predicted by BMI after controlling for age and partner variables. Conclusions: BMI did not impact sexual repertoire during the previous 4 weeks, with the exception of an increased odds ratio for penile–anal intercourse (OR = 1.06; 95% CI [1.02, 1.10]). Researchers and practitioners working with women should not assume limitations on women's sexual repertoires because of larger body size.     

Relationship Between Body Image and Body Mass Index in College Men

Objective and Participants: The authors examined cognitive and affective dimensions of body image of a randomized sample of 188 college men on the basis of body mass index (BMI). Methods: They conducted chi-square tests and ANOVAs to determine differences between 4 BMI groups (underweight, normal weight, overweight, and obese) on demographics and body image measures. Results: The authors found significant differences in regard to total body image (p < .001), weight or shape concern (p < .001), and body dissatisfaction (p < .001). BMI was significantly correlated with negative body image. Overweight and obese participants reported significantly higher levels of negative body image than did normal- and underweight participants. Overweight participants reported significantly higher weight and shape concerns than did underweight, normal-weight, and obese participants. In regard to body dissatisfaction, underweight, overweight, and obese participants reported significantly higher levels of body dissatisfaction than that reported by normal-weight participants. Conclusions: BMI may be an important factor in identifying potential body image disorders in college-aged men.     

Race‐Ethnicity,Union Status,and Change in Body Mass Index in Young Adulthood

This study used data from three waves of the National Longitudinal Study of Adolescent to Adult Health and fixed effects regression to consider whether associations between change in union status and change in body mass index (BMI) were moderated by race‐ethnicity. The results indicated that intimate unions were differentially associated with gains in BMI along racial‐ethnic lines, especially for women. When compared with White women, marriage was associated with larger increases in BMI for Black, Hispanic, and Multiracial women, and cohabitation was associated with larger increases for Black and Hispanic women. In contrast, marriage and cohabitation were associated with less weight gain for Asian when compared with White women. Among men, racial‐ethnic differences in the relationship between union status and BMI were similarly patterned but less pronounced. The results suggest that marital status further exacerbates racial‐ethnic disparities in BMI from adolescence to young adulthood.     

The College Health Advisor and the College Age Adoptee

Abstract

Eating disorders are among the most common psychopathologies on college campuses. Research on ethnic differences in eating disorder symptoms and prevalence has resulted in conflicting conclusions. Some studies find that particular ethnic groups have a higher prevalence of a symptom; others find that members of that ethnic group have a lower prevalence of the same symptom. The authors explored the role of body mass index (BMI), one potential confound. They used a reliable measure of eating disorder symptoms to assess differences between Hispanic, Asian, and non-Hispanic White college women from two separate samples. After controlling for BMI, ethnic differences in eating disorder symptoms of concern about weight and shape disappeared, but differences in restrained eating remained. Inconsistent findings in the ethnic-difference literature on eating disorders may result from systematic group differences in BMI. Implications for college health programs, counseling, and case finding are discussed.     

Individual and Familial Correlates of Body Satisfaction in Male and Female College Students

Abstract

Objective: This study investigates the relative contributions of global self-esteem, body mass index (BMI), dieting behaviors, and perceived parental control and care on body satisfaction among a nonclinical sample of college students. Participants and Methods: Participants (49 males and 299 females) reported weight and height (to calculate BMI) and completed the EAT 26 test. Perceived parental care and control, global self-esteem, and body satisfaction were measured and examined in relation to BMI and dieting behavior. Results: High BMIs were associated with lower body satisfaction for both genders; dieting behavior, self-esteem, and perceived parental care and control demonstrated a unique gender-specific association among variables in prediction of body satisfaction and dieting behavior for each gender. Conclusions: Body satisfaction as a part of global self-esteem is constructed differently by males and females. Various aspects of parenting (care and control) are associated with self-esteem and body satisfaction for each gender, influencing dieting behavior.     

Ethnic differences in eating disorder symptoms among college students: the confounding role of body mass index.

Eating disorders are among the most common psychopathologies on college campuses. Research on ethnic differences in eating disorder symptoms and prevalence has resulted in conflicting conclusions. Some studies find that particular ethnic groups have a higher prevalence of a symptom; others find that members of that ethnic group have a lower prevalence of the same symptom. The authors explored the role of body mass index (BMI), one potential confound. They used a reliable measure of eating disorder symptoms to assess differences between Hispanic, Asian, and non-Hispanic White college women from two separate samples. After controlling for BMI, ethnic differences in eating disorder symptoms of concern about weight and shape disappeared, but differences in restrained eating remained. Inconsistent findings in the ethnic-difference literature on eating disorders may result from systematic group differences in BMI. Implications for college health programs, counseling, and case finding are discussed.     

Gender,Race/Ethnicity,and Deviant Drinking: A Longitudinal Application of Social Structure and Social Learning Theory

Aker's (1998) theory of social structure and social learning (SSSL) argues that structural variations in deviant behavior, such as gender or race/ethnic differences in underage or heavy drinking, are mediated by social learning variables. However, longitudinal analyses of deviant drinking in an urban sample of white, black, and Hispanic adolescents fail to support the SSSL mediation hypothesis. Significant gender and race/ethnic differences persist after controls for social learning variables as well as for social bonding variables. Interaction effects involving two social bonding variables—family attachment and moral belief—point to theoretically important conditions that maintain a gender gap in underage drinking and relatively low levels of deviant drinking among African American adolescents.     

Becoming Overweight without Gaining a Pound: Weight Evaluations and the Social Integration of Mexicans in the United States

Mexican women gain weight with increasing duration in the United States. In the United States, body dissatisfaction tends to be associated with depression, disordered eating, and incongruent weight evaluations, particularly among white women and women of higher socioeconomic status. However, it remains unclear how being overweight and obesity are interpreted by Mexican women. Using comparable data of women aged 20–64 from both Mexico (the 2006 Encuesta Nacional de Salud y Nutricion; N = 17,012) and the United States (the 1999–2009 National Health and Nutrition Examination Surveys; N = 8,487), we compare weight status evaluations among Mexican nationals, Mexican immigrants, US‐born Mexicans, US‐born non‐Hispanic whites, and US‐born non‐Hispanic blacks. Logistic regression analyses, which control for demographic and socioeconomic variables and measured body mass index and adjust for the likelihood of migration for Mexican nationals, indicate that the tendency to self‐evaluate as overweight among Mexicans converges with levels among non‐Hispanic whites and diverges from blacks over time in the United States. Overall, the results suggest a US integration process in which Mexican‐American women's less critical self‐evaluations originate in Mexico but fade with time in the United States as they gradually adopt US white norms for thinner body sizes. These results are discussed in light of prior research about social comparison and negative health assimilation.     

Friendship Groups,Personal Motivation,and Gender in Relation to High School Students' STEM Career Interest

Friendship group characteristics, motivation, and gender were investigated in relation to adolescents' science, technology, engineering, and math (STEM) career interest. The sample was comprised of 468 high school students (M = 16 years, range = 13–18) from diverse ethnic backgrounds. Participants rated their friendship group's support of STEM as well as their personal motivation in science. They separately rated the friendship group's support of English and personal motivation in English. Other predictors included friendship group characteristics (importance, gender composition) and background variables such as gender. Group support of STEM (but not English) and science motivation (but not English motivation) predicted STEM career interest. Group characteristics and participant gender moderated the effects. Findings suggest social identities and self‐concepts may shape youths' STEM career choices.     

Hispanic Assimilation and Fertility in New U.S. Destinations

This paper evaluates comparative patterns of fertility in new Hispanic destinations and established gateways using pooled cross‐sectional data from the 2005–2009 microdata files of the American Community Survey. Changing Hispanic fertility provides a useful indicator of cultural incorporation. Analyses show that high fertility among Hispanics has been driven in part by the Mexican origin and other new immigrant populations (e.g., non‐citizens, those with poor English language skills, etc.). However, high fertility rates among Hispanics cannot be explained entirely by sociodemographical characteristics that place them at higher risk of fertility. For 2005–2009, Hispanic fertility rates were 48 percent higher than fertility among whites; they were roughly 25 percent higher after accounting for differences in key social characteristics, such as age, nativity, country of origin, and education. Contrary to most previous findings of spatial assimilation among in‐migrants, fertility rates among Hispanics in new destinations exceeded fertility in established gateways by 18 percent. In the multivariate analyses, Hispanics in new destinations were roughly 10 percent more likely to have had a child in the past year than those living in established gateways. Results are consistent with subcultural explanations of Hispanic fertility and raise new questions about the spatial patterning of assimilation and the formation of ethnic enclaves outside traditional settlement areas.     

Body mass index,waist/hip ratio and androgen—estrogen activity in younger versus older Polish men

This study was performed to evaluate the associations between estradiol, dehydroepiandrosterone sulfate (DHEAS), free and total testosterone levels, and anthropometric parameters of general adiposity (body mass index, BMI) and fat distribution (waist/hip ratio, WHR), separately in two subgroups of healthy Polish men: younger (aged 22–39 years, n = 95) and older (aged 40 years and over, n = 141) subjects. Sex steroid levels were assessed using radioimmunoassay (RIA). BMI was used as a measure of general adiposity. WHR was used to estimate distribution of adipose depots. The relationships between sex steroids, BMI, WHR and age were evaluated by use of non-parametric statistics (Spearman coefficients). Aging was related to a reduction of all hormone levels (correlation coefficients with age: free testosterone r = -0.52, p < 0.001; total testosterone r = -0.25, p < 0.001; estradiol r = -0.18, p < 0.001; DHEAS r = -0.45, p < 0.001) and an increase of BMI and WHR for BMI r = 0.23, p < 0.001; for WHR r = 0.47, p < 0.001). A one way analysis of co-variance (ANCOVA) was applied separately in the two subgroups of subjects to assess the relationships between hormonal and anthropometric variables. In men aged 22–39 years, the total (but not free) testosterone and DHEAS (when controlled for age) significantly differentiated BMI values. In subjects aged 40 years and over, no associations between sex steroids and BMI were revealed. In younger males DHEAS differentiated WHR values (even when controlled for age and BMI), whereas after the age of 40 years an increased WHR was accompanied by increases in both estradiol and DHEAS levels. The associations between the androgen—estrogen activity and the anthropometric parameters of adiposity vary in younger versus older healthy men.     

Body mass index and functional status in community dwelling older Turkish males

Abstract

Objectives: To assess sex hormones in men with obesity and prostate cancer (PCa) and to study association between androgens and the pathogenesis biology of PCa in vitro.

Subjects and methods: One hundred and eighty-one men older than 45?years selected from of a population attending to Urology departments screening for PCa, (78 participants without PCa and 103 patients with PCa). All participants were assessed for body mass index (BMI), age, Gleason score, and PSA. Endocrine profile was determined for LH, total testosterone (TT), 17β-estradiol (E2), prolactin and leptin. Biochemical profile (HbA1c, triacylglycerols and lipoproteins) was also determined. In vitro experiments were also performed, involving the study of 5α-dihydrotestosterone (DHT) and E2 in the presence of adipocyte-conditioned medium (aCM).

Results: All variables were continuous and described a Gaussian distribution unless mentioned. To determine the relation of aggressiveness, variable were transformed into categories. Thus, PCa aggressiveness is associated with the increase of age and BMI (p?<?.0001) but with is decreased with TT and E2 (p?<?.05). Moreover, adipocyte-secreted molecules increase aggressiveness of PCa cells in vitro. Lastly, DTH but not E2 enables invasiveness in vitro.

Conclusions: It was observed a coexistence of hormone axis profile alteration with sex hormones and BMI in PCa patients, in accordance with the new perspective of PCa pathogenesis.     

Negative Stereotypes of Ethnic Outgroups: A Longitudinal Examination Among Palestinian,Israeli Jewish,and Israeli Arab Youth

Ethno‐political conflict impacts thousands of youth globally and has been associated with a number of negative psychological outcomes. Extant literature has mostly addressed the adverse emotional and behavioral outcomes of exposure while failing to examine change over time in social cognitive factors in contexts of ethno‐political conflict. Using cohort sequential longitudinal data, this study examines ethnic variation in the development of negative stereotypes about ethnic outgroups among Palestinian (n = 600), Israeli Jewish (n = 451), and Israeli Arab (n = 450) youth over 3 years. Age and exposure to ethno‐political violence were included as covariates for these trajectories. Findings indicate important ethnic differences in trajectories of negative stereotypes about ethnic outgroups, as well as variation in how such trajectories are shaped by prolonged ethno‐political conflict.     

Extended Family Integration Among Euro and Mexican Americans: Ethnicity,Gender, and Class

This article compares the extended family integration of Euro and Mexican American women and men and assesses the importance of class and culture in explaining ethnic differences. Using National Survey of Families and Households II data (N = 7,929), we find that ethnic differences depend on the dimension of integration. Mexican Americans exhibit higher rates of kin coresidence and proximity, but lower rates of financial support than Euro Americans. Two additional differences exist only among women: Mexican American women are more likely than Euro American women to give household or child care help. As to the explanation for these differences, social class is the key factor; cultural variables have little effect. Our findings support a theoretical framework attending to intersections among ethnicity, gender, and class.     

Marriage Delay,Time to Play? Marital Horizons and Hooking Up in College

Previous research suggests that an increasing age at first marriage has contributed to the prevalence of sexual hookups on U.S. college campuses. In this article, we use life course and marital horizons theories to analyze the influence of ideal age at first marriage on hooking up among unmarried heterosexual college students. Analyses of the Online College Social Life Survey (N = 17,981) show a positive association between ideal age at first marriage and hookups for most students, but not for students whose mothers have no post‐secondary education, Asian men, Asian women, and Latina women. Variation in ideal marriage timing does not account for gender, racial/ethnic, and class gaps in hookup participation. Results are discussed with reference to the role of sexuality in processes of stratification throughout young adulthood.     

The Grand Challenge of Reducing Gender and Racial/Ethnic Disparities in Service Access and Needs Among Adults with Alcohol Misuse

This study examined the impact of the Affordable Care Act (ACA) on gender and racial and ethnic disparities in accessing and using behavioral health services among a national sample of adults who reported heavy or binge alcohol use (n = 52,496) and those with alcohol use disorder (AUD; n = 22,966). Difference-in-differences models estimated service-related disparities before (2008–2009) and after (2011–2014) health care reform. A subanalysis was conducted before (2011–2013) and after (2014) full implementation of the ACA. Asian subgroups among respondents with heavy or binge drinking were excluded from substance use disorder (SUD) treatment and unmet need outcome models due to insufficient cell size. Among heavy or binge drinkers, unmet SUD treatment need decreased among Black women and increased among Black men. Mental health (MH) treatment decreased among Asian men, whereas unmet MH treatment need decreased among Hispanic men. MH treatment increased among Hispanic women with AUD. Although there were improvements in service use and access among Black and Hispanic women and Hispanic men, there were setbacks among Black and Asian men. Implications for social workers are discussed.     

Immigration and the American Obesity Epidemic1

Immigration is an important population dynamic at work in the U.S., but we know little about its impact on American obesity. Built on nutrition transition and immigration theories, this paper provides explanations for immigrants’ initial body composition advantage, its partial erosion over time, and the gender difference in the erosion. We find evidence that the American obesity epidemic would be much more severe without the mass immigration that began in 1965. In addition to confirming the erosion in immigrants’ body composition advantage, we further find that this erosion is weaker for men than for women. Once immigration’s impact is teased out, racial/ethnic disparities in body composition greatly differ from what we observe. This study provides gender‐specific estimates for the differences in obesity by nativity and residence duration and the net level of Hispanic‐white and Asian‐white disparities at the mean body mass index (BMI) as well as the overweight, Stage‐1, and Stage‐2 obesity cutoffs. Our findings suggest that immigration must be taken into account when addressing public health concerns.     

Factors that Influence Body Dissatisfaction: Comparisons across Culture and Gender

This study examined the relationship between attachment style, differentiation of self, and body dissatisfaction across culture and gender. The sample consisted of 115 Caucasians (85 females, 29 males) with a mean age of 22.2 years (SD = 5.81) and 119 Chinese individuals (93 females, 26 males) with a mean age of 22.8 years (SD = 2.35). Participants completed online self-report measures of body satisfaction, attachment style, and differentiation of self. Results indicated that high attachment anxiety and less differentiation of self were associated with lower body satisfaction for women but not for men of either cultural group. There were no significant cultural or gender differences in terms of overall body satisfaction; however, there were differences with regard to preoccupation with weight and self-perceived weight. It was concluded that culture had little impact on body dissatisfaction in the present sample but that the factors that shape body dissatisfaction differed by gender.     

Pilot Testing a Cognitive-Behavioral Protocol on Psychosocial Predictors of Exercise,Nutrition, Weight,and Body Satisfaction Changes in a College-Level Health-Related Fitness Course

Abstract

Objective: Small-scale pilot testing of supplementing a required college health-related fitness course with a cognitive-behavioral exercise-support protocol (The Coach Approach). Participants: Three classes were randomly assigned to Usual processes (n = 32), Coach Approach–supplemented: Mid-size Groups (n = 32), and Coach Approach–supplemented: Small Groups (n = 34) conditions. Methods: Repeated-measures analyses of variance (ANOVAs) assessed overall and between-class changes in the behavioral/physiological factors of exercise, fruit/vegetable intake, and body mass index (BMI); and the psychosocial factors of self-regulation, exercise self-efficacy, mood, and body satisfaction. Dependent t tests evaluated within-class changes. Multiple regression analyses tested prediction of exercise by changes in self-regulation, self-efficacy, and mood. Results: Significant improvements in self-regulation and fruit/vegetable intake were found in all classes. The Coach Approach–supplemented classes demonstrated significant increases in exercise. Significant improvements in BMI, self-efficacy, and body satisfaction were found in only The Coach Approach–supplemented: Small Groups class. Psychosocial changes predicted increased exercise. Self-regulation was the strongest contributor. Conclusions: Overall, results were positive and warrant more comprehensive testing.
