Refusing expectation? Class, masculinity and selfhood in a longitudinal analysis of young men’s educational transitions/trajectories, age 10–22

Young African-American men have altered macrovascular and microvascular function. In this cross-sectional study, we tested the hypothesis that vascular dysfunction in young African-American men would contribute to greater central blood pressure (BP) compared with young white men. Fifty-five young (23 yr), healthy men (25 African-American and 30 white) underwent measures of vascular structure and function, including carotid artery intima-media thickness (IMT) and carotid artery beta-stiffness via ultrasonography, aortic pulse wave velocity, aortic augmentation index (AIx), and wave reflection travel time (Tr) via radial artery tonometery and a generalized transfer function, and microvascular vasodilatory capacity of forearm resistance arteries with strain-gauge plethysmography. African-American men had similar brachial systolic BP (SBP) but greater aortic SBP (P<0.05) and carotid SBP (P<0.05). African-American men also had greater carotid IMT, greater carotid beta-stiffness, greater aortic stiffness and AIx, reduced aortic Tr and reduced peak hyperemic, and total hyperemic forearm blood flow compared with white men (P<0.05). In conclusion, young African-American men have greater central BP, despite comparable brachial BP, compared with young white men. Diffuse macrovascular and microvascular dysfunction manifesting as carotid hypertrophy, increased stiffness of central elastic arteries, heightened resistance artery constriction/blunted resistance artery dilation, and greater arterial wave reflection are present at a young age in apparently healthy African-American men, and conventional brachial BP measurement does not reflect this vascular burden.

Background: Race disparities in cardiovascular disease (CVD) related morbidity and mortality are evident among men. While previous studies show health in young adulthood and racial residential segregation (RRS) are important factors for CVD risk, these factors have not been widely studied in male populations. We sought to examine race differences in ideal cardiovascular health (CVH) among young men (ages 24–34) and whether RRS influenced this association. Methods: We used cross-sectional data from young men who participated in Wave IV (2008) of the National Longitudinal Survey of Adolescent to Adult Health (N = 5080). The dichotomous outcome, achieving ideal CVH, was defined as having ≥4 of the American Heart Association’s Life’s Simple 7 targets. Race (Black/White) and RRS (proportion of White residents in census tract) were the independent variables. Descriptive and multivariate analyses were conducted. Results: Young Black men had lower odds of achieving ideal CVH (OR = 0.67, 95% CI = 0.49, 0.92) than young White men. However, RRS did not have a significant effect on race differences in ideal CVH until the proportion of White residents was ≥55%. Conclusions: Among young Black and White men, RRS is an important factor to consider when seeking to understand CVH and reduce future cardiovascular risk.

Young Adults Are Worse Off Than Adolescents

Fesoterodine, a new antimuscarinic agent for overactive bladder, undergoes immediate and extensive hydrolysis by nonspecific esterases to 5-hydroxymethyl tolterodine (5-HMT), the metabolite principally responsible for its antimuscarinic activity. Formation of 5-HMT does not require cytochrome P450 (CYP)-mediated metabolism, but its further metabolism and inactivation involves CYP3A4 and CYP2D6 isoenzymes. Subject age, gender, and race can play a key role in inter-subject variability in pharmacokinetics and thus efficacy and safety of drugs. This article examines the effects of age, gender, and race on the pharmacokinetics and pharmacodynamics of fesoterodine. Data from two randomized, double-blind, placebo-controlled, parallel-group trials in healthy subjects are presented: Study 1 investigated the effects of race (white vs. black men) and Study 2 investigated the effects of age (young vs. old men) and gender (elderly men vs. elderly women) on the pharmacokinetics and pharmacodynamics of single doses of fesoterodine 8 mg. In both studies, the primary endpoints were area under the concentration-time curve up to the last sample (AUC0-tz) and maximum concentration (Cmax) of 5-HMT in plasma. Pharmacodynamic variables included spontaneous salivary secretion (Studies 1 and 2) and residual urine volume (Study 2 only). The two studies included 5 groups of 16 subjects each (randomized 3 : 1 to fesoterodine or placebo): white men aged 18 - 45 years, black men aged 18 - 45 years (Study 1); young white men aged 18 - 40 years, elderly white men aged > 65 years, and elderly white women aged > 65 years (Study 2). There were no clinically meaningful differences in the primary endpoints between white and black subjects or between young white men, elderly white men, and elderly white women. Mean AUC0-tz was 70.7 ng/ml x h in whites and 64.1 ng/ml x h in blacks; mean Cmax was 6.1 and 5.5 ng/ml in whites and blacks, respectively. Mean AUC0-tz in young white men, elderly white men, and elderly white women was 49, 48, and 54 ng/ml x h, respectively; mean Cmax in young white men, elderly white men, and elderly white women was 4.1, 3.8, and 4.6 ng/ml, respectively. Consistent with the anticholinergic pharmacology of fesoterodine, declines in salivary volume were observed in both studies, and elevations in residual urinary volume were observed, especially in elderly subjects, in Study 2. Fesoterodine was well tolerated, with common adverse events such as headache and dry mouth recognized as antimuscarinic class effects. Subject demographics, such as age, gender, and race, do not have a clinically meaningful effect on 5-HMT pharmacokinetics or pharmacodynamics after single-dose administration of fesoterodine 8 mg; thus, no dosage adjustment is required for fesoterodine based on age, gender, or race.

The Great Recession had a devastating impact on labor force participation and employment. This impact was not unlike other recessions, except in size. The recovery, however, has been unusual not so much for its sluggishness but for the unusual pattern of recovery in employment by race. The Black employment–population rate has increased since bottoming out in 2010 while the White employment–population rate has remained flat. We examine trends in labor force participation and employment by race, sex, and age and determine that the explanation is a combination of an aging White population and an increase in labor force participation among younger Black people. We estimate the likelihood of labor force participation and employment among young men and women to control for confounding factors, such as changes in educational characteristics. We then decompose the gaps among groups and the changes over time in labor force participation using an Oaxaca–Blinder-like technique for nonlinear estimations. We find that much smaller negative impacts of characteristics and greater returns to characteristics among young Black men and women than among young White men and women explain the observed trends.

Black Employment Trends since the Great Recession

This article explores an important, yet infrequently explored, topic in youth studies: far-right festivals. Drawing upon contemporary international examples, this article suggests the powerful imagery of embodied militancy in far-right festivals may cut through to potential young recruits, especially young men, on a visceral and emotional level. They experience a strong sense of nationalist heritage, cultural belonging and radical political identity. Youth may be attracted to the far-right through festivals because they seem to be an exciting space to express resistance against the mainstream, including hatred for ethnic minorities. There is an active process of becoming that takes place. Through collectively lived experience, young people, especially young white men, are guided towards right-wing extremist membership. Such events offer not only a powerful face-to-face experience for youth, but later become a compelling digital recruitment tool, targeted at young people, when photos and videos of the festival are uploaded on social media.

When serious public disorder exploded onto the streets of Bradford, West Yorkshire in June 1995, involving mostly ‘Muslim’ and some white and black young men, the cause was identified as a widening cultural and generation gap within the Asian community. Keith Hellawell, then Chief Constable of West Yorkshire Police, stated that ‘Cultural and religious leaders have been worried for the past ten years or so that the younger generation don’t follow their teachings and feel that they have great difficulty in controlling them’ (quoted in the Independent 12 June 95). The notion of an intergenerational crisis within the British Muslim community has taken hold ever since and has been returned to again and again. As if on cue, the serious public disorders, again mostly involving Muslim and some white young men, in Bradford, Oldham and Burnley – all former textile towns in Northern England – in the spring and summer of 2001, spectacularly compounded suspicion of crisis and disaffection. Almost immediately the drama was eclipsed by the epoch-making but wholly unrelated terrorist attacks in the United States. Worries about disorder and disaffection were displaced by fear of terrorist attack as the UK joined the US’s ‘asymmetrical’ ‘war on terror’. The war was brought home with a vengeance by the bomb attacks in London (2005) and Glasgow (2007), the two failed shoe bombers (2001 and 2010) and the 2003 bombing in Tel Aviv, carried out by British-born ‘Islamic political terrorists’ (Abbas 2007). Taking its cue from the response to the earlier disorders, the government launched its action plan ‘Preventing violent extremism: winning hearts and minds’ in April 2007, to support community cohesion and strengthen the role of faith institutions and leaders in resisting violent extremism. This religious inflection clearly targeted the British Muslim community as the main harbingers of cohesion and security.KeywordsYoung PeopleMuslim CommunityIntergenerational MobilityViolent ExtremismMuslim IdentityThese keywords were added by machine and not by the authors.

PURPOSE: Young African American men have stiffer large central arteries, impaired dilation of smaller peripheral arteries and greater central blood pressure (BP) when compared to their white peers. The purpose of this study was to examine the effect of resistance exercise training (RT) on vascular function and central BP in young (age 22 yrs) African American and white men. METHODS: Vascular and hemodynamic measures were made in 19 African American and 18 white men at baseline and following 6-weeks of RT. Carotid BP and carotid artery beta-stiffness were measured by tonometry and ultrasonography respectively. Aortic BP and augmentation index (AIx) were measured by radial artery tonometry and a generalized transfer function. Aortic and brachial stiffness were measured by pulse wave velocity (PWV). Brachial blood flow was assessed by Doppler ultrasonography. Forearm blood flow was measured by strain-gauge plethysmography at rest and during reactive hyperemia (RH) induced by 5-min of upper arm occlusion. RESULTS: There were similar reductions in aortic systolic BP, carotid systolic BP, forearm vascular resistance and brachial vascular resistance in both African American and white men following training (p<0.05). There were similar increases in peak forearm blood flow and forearm blood flow area under the curve measured during RH in both African American and white men following training (p<0.05). There were no changes in brachial systolic BP, carotid stiffness, aortic AIx, aortic PWV, and brachial PWV in either group (p>0.05). CONCLUSIONS: RT reduced central BP while having no effect on brachial BP in young African American and white men. Resistance exercise training appears to be a useful lifestyle intervention for improving peripheral vascular function while not detrimentally affecting central vascular function in young African American men.

To evaluate the incidence of oral cavity squamous cell carcinoma (OCSCC) and oral tongue squamous cell carcinoma (OTSCC) in young white women, age 18 to 44 years. We analyzed incidence and survival data from the Surveillance, Epidemiology and End Results (SEER) Program of the National Cancer Institute from 1975 to 2007 for OCSCC and OTSCC. Three cohorts were examined: all ages, age 18 to 44 years (ie, "young"), and age > 44 years. Individuals were stratified by sex and/or race. Percentage change (PC) and annual percentage change (APC) were calculated. Joinpoint regression analyses were performed to examine trend differences. Overall, incidence of OCSCC was decreasing for all ages. However, incidence was increasing for young white women (PC, 34.8; APC, 2.2; P < .05). Incidence of OTSCC was decreasing for all ages except in the age 18 to 44 years group (PC, 28.8; APC, 1.8; P < .05). Young white individuals had increasing incidence trends of OTSCC (white women: PC, 111.3; APC, 4; P < .05; young white men: PC, 43.7; APC, 1.6; P < .05). The APC of OTSCC was significantly greater in young white women compared with that in young white men (P = .007). Furthermore, incidence of SCC in all other subsites of the oral cavity was decreasing. Nonwhites had a decreasing incidence of OCSCC and OTSCC. Cause-specific survival was similar among whites age 18 to 44 and individuals older than age 44 years. OTSCC is increasing among young white individuals age 18 to 44 years, particularly among white women. Young white women may be a new, emerging head and neck cancer patient population.

The preceding article in this series1 reviewed evidence as to why age-associated changes in the central arterial system are risky with respect to vascular disease. In a similar vane, the focus of this article is on the potential link between age-associated changes in the heart and clinical cardiac disease outcomes. Left ventricular hypertrophy, heart failure, and atrial fibrillation increase dramatically with age (Figure 1). The prevalence of left ventricular hypertrophy (LVH) also increases with rising blood pressure and body mass index, a measure of obesity.2–4 Whether identified by electrocardiography or echocardiography, left ventricular hypertrophy has been shown to be associated with increased risk for coronary heart disease, sudden death, stroke, and overall cardiovascular disease.4,5 Figure 1.

Previous studies suggest that male testosterone concentrations have declined over time. To explore this in a large US population, we examined testosterone and free testosterone concentrations in National Health and Nutrition Examination Surveys (NHANES) from 1988-1991 and 1999-2004. We also examined sex hormone-binding globulin (SHBG), estradiol, and androstanediol glucuronide (3α-diol-G) over the same period. Non-Hispanic white, non-Hispanic black, and Mexican-American men from 1988-1991 and 1999-2004 NHANES surveys who were ≥20 years old and had serum from morning blood draws were included in this analysis (1988-1991: N = 1,413; 1999-2004: N = 902). Testosterone, estradiol and SHBG were measured by competitive electrochemiluminescence immunoassays and 3α-diol-G was measured by enzyme immunoassay. Free testosterone was calculated using testosterone and SHBG values. Adjusted mean hormone concentrations were estimated using linear regression, accounting for NHANES sampling weights and design, age, race/ethnicity, body mass index, waist circumference, alcohol use and smoking. Differences in adjusted mean concentrations (Δ) and two-sided p-values were calculated; p < 0.05 was statistically significant. Overall, 3α-diol-G and estradiol declined between 1988-1991 and 1999-2004, but there was little change in testosterone, free testosterone, or SHBG (Δ: 3α-diol-G = -1.83 ng/mL, p < 0.01; estradiol = -6.07 pg/mL, p < 0.01; testosterone = -0.03 ng/mL, p = 0.75; free testosterone = -0.001 ng/mL, p = 0.67; SHBG = -1.17 nmol/L, p = 0.19). Stratification by age and race revealed that SHBG and 3α-diol-G declined among whites 20-44 years old (Δ: SHBG = -5.14 nmol/L, p < 0.01; 3α-diol-G = -2.89 ng/mL, p < 0.01) and free testosterone increased among blacks 20-44 years old (Δ: 0.014 ng/mL, p = 0.03). Estradiol declined among all ages of whites and Mexican-Americans. In conclusion, there was no evidence for testosterone decline between 1988-1991 and 1999-2004 in the US general population. Subgroup analyses suggest that SHBG and 3α-diol-G declined in young white men, estradiol declined in white and Mexican-American men, and free testosterone increased in young black men. These changes may be related to the increasing prevalence of reproductive disorders in young men.

Cigarette smoking prevalence is more than two times greater among incarcerated adults, a population usually excluded from national health surveys. African American young adult (18-25) men are less likely to smoke cigarettes than their white counterparts. However, they are two and a-half-times more likely to be incarcerated. This study estimated smoking prevalence with noninstitutionalized and incarcerated samples combined to determine if excluding incarcerated adults impacts smoking prevalence for certain populations. The Bureau of Justice Statistics last fielded the Survey of Inmates in State and Federal Correction Facilities in 2003-2004. We combined data from Survey of Inmates in State and Federal Correction Facilities (n = 17 910) and the 2003 and 2004 National Health Interview Survey (n = 61 470) to calculate combined cigarette smoking estimates by race/ethnicity, sex, and age. Inmates represented the greatest proportion of smokers among African American men. Among African American young adult men, inmates represented 15.2% of all smokers in the combined population, compared to 2.0% among white young adult men. Cigarette smoking prevalence was 17.6% in the noninstitutionalized population of young adult African American men and 19.7% in the combined population. Among white young adult men, cigarette smoking prevalence was 29.8% in the noninstitutionalized population, and 30.2% in the combined population. There was little difference in estimates among women. The exclusion of incarcerated African American young adult men may result in a small underestimation of cigarette smoking prevalence in this population. Increasing access to smoking cessation support among inmates may reduce smoking prevalence in disproportionately incarcerated segments of the US population. The exclusion of incarcerated adults from national survey data should be considered when examining differences in cigarette smoking prevalence estimates between African American and white young adult men. Approximately one in six African American young adult men who smoke were incarcerated. Increasing access to smoking cessation support among inmates may reduce smoking prevalence among disproportionately incarcerated segments of the population.
