Adolescent Reproductive Knowledge, Attitudes, and Beliefs and Future Fatherhood.

PurposeWith a growing focus on the importance of men's reproductive health, including preconception health, the ways in which young men's knowledge, attitudes, and beliefs (KAB) predict their reproductive paths are understudied. To determine if reproductive KAB predicts fatherhood status, timing and residency (living with child or not).MethodsReproductive KAB and fatherhood outcomes were analyzed from the National Longitudinal Study of Adolescent Health, a 20-year, nationally representative study of individuals from adolescence into adulthood. Four measures of reproductive KAB were assessed during adolescence in waves I and II. A generalized linear latent and mixed model predicted future fatherhood status (nonfather, resident/nonresident father, adolescent father) and timing while controlling for other socio-demographic variables.ResultsOf the 10,253 men, 3,425 were fathers (686 nonresident/2,739 resident) by wave IV. Higher risky sexual behavior scores significantly increased the odds of becoming nonresident father (odds ratio [OR], 1.30; p < .0001), resident father (OR, 1.07; p = .007), and adolescent father (OR, 1.71; p < .0001); higher pregnancy attitudes scores significantly increased the odds of becoming a nonresident father (OR, 1.20; p < .0001) and resident father (OR, 1.11; p < .0001); higher birth control self-efficacy scores significantly decreased the odds of becoming a nonresident father (OR, .72; p < .0001) and adolescent father (OR, .56; p = .01).ConclusionsYoung men's KAB in adolescence predicts their future fatherhood and residency status. Strategies that address adolescent males' reproductive KAB are needed in the prevention of unintended reproductive consequences such as early and nonresident fatherhood

Longitudinal Study of Body Mass Index in Young Males and the Transition to Fatherhood.

Despite a growing understanding that the social determinants of health have an impact on body mass index (BMI), the role of fatherhood on young men's BMI is understudied. This longitudinal study examines BMI in young men over time as they transition from adolescence into fatherhood in a nationally representative sample. Data from all four waves of the National Longitudinal Study of Adolescent Health supported a 20-year longitudinal analysis of 10,253 men beginning in 1994. A "fatherhood-year" data set was created and changes in BMI were examined based on fatherhood status (nonfather, nonresident father, resident father), fatherhood years, and covariates. Though age is positively associated with BMI over all years for all men, comparing nonresident and resident fathers with nonfathers reveals different trajectories based on fatherhood status. Entrance into fatherhood is associated with an increase in BMI trajectory for both nonresident and resident fathers, while nonfathers exhibit a decrease over the same period. In this longitudinal, population-based study, fatherhood and residence status play a role in men's BMI. Designing obesity prevention interventions for young men that begin in adolescence and carry through young adulthood should target the distinctive needs of these populations, potentially improving their health outcomes

Polarization is the Psychological Foundation of Collective Engagement

The term polarization is used to describe both the division of a society into opposing groups (political polarization), and a social psychological phenomenon (group polarization) whereby people adopt more extreme positions after discussion. We explain how group polarization underpins the political polarization phenomenon: Social interaction, for example through social media, enables groups to form in such a way that their beliefs about what should be done to change the world – and how this differs from the stance of other groups - become integrated as aspects of a new, shared social identity. This provides a basis for mobilization to collective action

New Technologies, New Identities, and the Growth of Mass Opposition in the Arab Spring

The recent revolutions known as the Arab Spring have been characterized as the products of social media. However, there is an alternative view that revolution takes place on the street or the battlefield and that the role of social media has been overstated. We argue that some new technologies can serve to facilitate rapid social change when they provide ways to overcome restrictions on the freedoms of expression and association. In doing so, communication technologies enable the formation of new social identities that can challenge existing social orders by promoting the growth of a social movement that is positioned as loyal to the nation and its people but opposed to the government. Our analyses focus on the role of social media in spreading video images of dissent and the links between this video material, satellite television, and mobile telephones in Tunisia and Egypt

#MeToo, #MenToo: how men's progressive and reactionary actions are shaped by defensiveness

Movements for progressive social change (e.g., Black Lives Matter, #MeToo) are commonly met with reactionary counter-movements that seek to protect the rights and interests of structurally advantaged groups (e.g., All Lives Matter, #MenToo). Drawing on the insights of the social identity approach and the needs-based model of reconciliation, the current research explores whether men's support for progressive and reactionary action (i.e., their intentions to promote women's rights and men's rights, respectively) are shaped by their need to defend their group's moral identity. Combined analyses of three samples (N = 733) showed that men's social identification was associated with their reduced intentions to act for women's rights and positively related to their intentions to promote men's rights—effects mediated by their need for positive moral identity and defensiveness regarding the issue of gendered violence. Overall, the findings suggest that defensive construals regarding group-based inequalities may not only present a barrier to men's engagement in collective action for gender equality, but might also underlie their participation in reactionary actions designed to advance the rights of their own (advantaged) group

17β-Estradiol inhibits proliferation and migration of human vascular smooth muscle cells: similar effects in cells from postmenopausal females and in males

Objectives: Cardiovascular disease is rare in premenopausal women, but increases after the menopause when hormone replacement therapy reduces coronary events. Vascular smooth muscle cell (SMC) proliferation and migration occur in atherosclerosis, restenosis and venous graft disease. We studied the effects of 17β-estradiol on SMC proliferation and migration. Methods: SMC were cultured from saphenous veins of postmenopausal women and age-matched men. Cell growth was determined by 3H-thymidine incorporation and cell counting. Migration of SMC was assessed in 4-well chambers. SMC were seeded in one corner and PDGF-BB in filter paper glued onto the opposite wall. Results: PDGF-BB (5 ng/ml for 24 h) similarly stimulated 3H-thymidine incorporation in female (511 ± 57%; n = 8) and male (528 ± 62%; n = 12) SMC. This was reduced by 17β-estradiol (10−8-10−6 M; female 313 ± 52%; male 337 ± 54%; P < 0.05). PDGF-BB increased the number of SMC (P < 0.0001 at 10 days) obtained from females (153 ± 3%; n = 5) and males (150 ± 4%; n = 5), which was inhibited by 17 β-estradiol (10−6 M; female 134 ± 7%; male 128 ± 5%; P < 0.05). Similar results were obtained with basic fibroblast growth factor. In contrast to 17β-estradiol, another steroid (dexamethasone) had no effects on 3H-thymidine incorporation in these cells stimulated with PDGF-BB. PDGF-BB (0.01-1 ng) stimulated SMC migration (P < 0.05) which was inhibited by 17β-estradiol (10−10-10−6 M; n = 5; P < 0.005). Conclusion: 17β-Estradiol inhibits growth-factor-induced SMC proliferation and migration regardless of gender. These effects of 17β-estradiol may contribute to its cardiovascular protective properties in postmenopausal women during replacement therap

"We must be the change we want to see in the world":integrating norms and identities through social interaction

In this article, we propose a social psychological mechanism for the formation of new social change movements. Here, we argue that social change follows the emergence of shared injunctive social norms that define new collective identities, and we systematically spell out the nature of the processes through which this comes about. We propose that these norms and identities are created and negotiated through validating communication about a normative conflict; resulting in an identity-norm nexus (INN), whereby people become the change they want to see in the world. We suggest that injunctive norms are routinely negotiated, validated, and integrated with shared identity in order to create the potential to effect change in the world. Norms and identities need not be integrated or connected in this way, but the power of social actors to form new social movements to bring about socio-political change will tend to be severely limited unless they can bring about the integration of identity and action

The association of physical function and physical activity with all-cause mortality and adverse clinical outcomes in non-dialysis chronic kidney disease : a systematic review

Objective: People with nondialysis-dependent chronic kidney disease (CKD) and renal transplant recipients (RTRs) have compromised physical function and reduced physical activity (PA) levels. Whilst established in healthy older adults and other chronic diseases, this association remains underexplored in CKD. We aimed to review the existing research investigating poor physical function and PA with clinical outcome in nondialysis CKD. Data sources: Electronic databases (PubMed, MEDLINE, EMBASE, Web of Science, Cochrane Central Register of Controlled Trials) were searched until December 2017 for cohort studies reporting objective or subjective measures of PA and physical function and the associations with adverse clinical outcomes and all-cause mortality in patients with nondialysis CKD stages 1–5 and RTRs. The protocol was registered on the International Prospective Register of Systematic Reviews (PROSPERO) (CRD42016039060). Review methods: Study quality was assessed using the Newcastle-Ottawa Scale and the Agency for Healthcare and Research Quality (AHRQ) standards. Results: A total of 29 studies were included; 12 reporting on physical function and 17 on PA. Only eight studies were conducted with RTRs. The majority were classified as ‘good’ according to the AHRQ standards. Although not appropriate for meta-analysis due to variance in the outcome measures reported, a coherent pattern was seen with higher mortality rates or prevalence of adverse clinical events associated with lower PA and physical function levels, irrespective of the measurement tool used. Sources of bias included incomplete description of participant flow through the study and over reliance on self-report measures. Conclusions: In nondialysis CKD, survival rates correlate with greater PA and physical function levels. Further trials are required to investigate causality and the effectiveness of physical function and PA interventions in improving outcomes. Future work should identify standard assessment protocols for PA and physical function
