New research provides evidence that oral contraceptive use is related to changes in brain structure and function. The study, published in Hormones and Behavior , indicates that oral contraceptive use during puberty might impact stress reactivity and also increase brain activity when working memory is engaged. The researchers used functional magnetic resonance imaging or functional MRI fMRI to examine the brain activity and structure of 75 women as they completed a test of working memory. In addition, women completed the Trier Social Stress Test, an experimentally verified stress-inducing scenario in which the participants are asked to give a speech and do mental arithmetic. Ismail and her colleagues found that oral contraceptive use was linked to increased activation in the prefrontal cortex during working memory processing for negatively arousing stimuli, such as images of a gun. Women who started using oral contraceptives during puberty or adolescence displayed a blunted cortisol response following the stress test. In particular, women who started using oral contraceptives during puberty or adolescence displayed more brain activity in the bilateral lingual gyrus, midtemporal gyrus, pre-central gyrus, and insula during working memory processing of neutral images. Oral contraceptive use during puberty was also associated with structural changes in brain regions implicated in emotion regulation and memory, such as the fusiform gyrus and precuneus. One possibility is depression. Some women have complained of depression symptoms during oral contraceptive use.

By Saul McLeod , updated The Strange situation is a standardized procedure devised by Mary Ainsworth in the s to observe attachment security in children within the context of caregiver relationships. It applies to infants between the age of nine and 18 months. The procedure involves series of eight episodes lasting approximately 3 minutes each, whereby a mother, child and stranger are introduced, separated and reunited.

This report examines 1 the prevalence of psychological and minor physical violence victimization in a nationally representative sample of adolescents and 2 associations between sociodemographic factors and victimization. Analyses are based on adolescents who reported exclusively heterosexual romantic relationships in the National Longitudinal Study of Adolescent Health. Items from the Conflict Tactics Scale were used to measure victimization. Associations between victimization patterns and sociodemographic characteristics were assessed with polytomous logistic regression.
Although most sociodemographic characteristics were significantly associated with victimization, patterns varied by sex and type of victimization. Psychological and minor physical violence victimization is common in opposite-sex romantic relationships during adolescence. The sex-specific associations between sociodemographic characteristics and patterns of partner violence victimization underscore the importance of pursuing longitudinal, theory-driven investigations of the characteristics and developmental histories of both partners in a couple to advance understanding of this public health problem.
Violence between intimate partners is a significant public health problem and is thought to be most prevalent in early adulthood.

Life expectancy is the key metric for assessing population health. Broader than the narrow metric of the infant and child mortality , which focus solely at mortality at a young age, life expectancy captures the mortality along the entire life course. It tells us the average age of death in a population. Estimates suggest that in a pre-modern, poor world, life expectancy was around 30 years in all regions of the world.
Life expectancy has increased rapidly since the Age of Enlightenment. In the early 19th century, life expectancy started to increase in the early industrialized countries while it stayed low in the rest of the world.

Jump to navigation. Goncy’s program of research focuses on the importance of relationships e. Secondary interests include person-centered and variable-centered approaches to measurement, treatment implementation and fidelity, and development and evaluation of prevention and intervention programs in these areas. She also applies innovative methods and statistical techniques to promote science on issues such as measurement, longitudinal modeling, and use of multi-method or cross-informant data.
Goncy is currently conducting two-mixed method studies to examine relationship factors in young adults. These studies will include interviewing young adults about their opinions related to relationships, as well as having participants complete a series of questionnaires. In DYAD2, couples are brought in to complete similar tasks and also complete a video-taped set of tasks together. Students interested in gaining research experience may apply as an RA for this project, which is currently in progress.

Human sexuality is the way people experience and express themselves sexually. Someone’s sexual orientation is their pattern of sexual interest in the opposite or same sex. Social aspects deal with the effects of human society on one’s sexuality, while spirituality concerns an individual’s spiritual connection with others. Sexuality also affects and is affected by cultural, political, legal, philosophical, moral , ethical , and religious aspects of life. Interest in sexual activity typically increases when an individual reaches puberty.
Hypothesized social causes are supported by only weak evidence, distorted by numerous confounding factors.

See the CME Quiz. Vision screening in children is an ongoing process, with components that should occur at each well-child visit. The purpose is to detect risk factors and visual abnormalities that necessitate treatment and to identify those patients who require referral to an ophthalmologist skilled in examining children. Screening can reveal conditions commonly treated in primary care and can aid in discussion of visual concerns with parents or caregivers.
Vision screening begins with a review of family and personal vision history to identify risk factors requiring referral, including premature birth, Down syndrome, cerebral palsy, and a family history of strabismus, amblyopia, retinoblastoma, childhood glaucoma, childhood cataracts, or ocular or genetic systemic disease. Visual acuity measurement and external ocular examination are performed to recognize refractive error, childhood glaucoma, and various ocular conditions.

Theory and research suggest that there may be significant heterogeneity in the development, manifestation, and consequences of adolescent dating violence that is not yet well understood. Cultural parent acculturation, acculturation conflict , family conflict and cohesion and individual normative beliefs, conflict resolution skills, self-control risk and protective factors were associated with class membership. Membership in the multiform versus the uninvolved class was concurrently associated with emotional distress among girls and predicted emotional distress longitudinally among boys.
The results contribute to understanding heterogeneity in patterns of involvement in dating violence among Latino youth that may reflect distinct etiological processes. Estimates from nationally representative surveys in the U. Although dating violence affects youth in all ethnic and racial groups, research suggests that Latino youth represent a growing population who may be particularly at risk. Census projections estimate that the proportion of youth under the age of 18 in the U.
Although progress has been made in characterizing the etiology of dating violence, considerable knowledge gaps remain. In particular, one area that has received scant research attention among adolescents, and no attention in studies of Latino youth, is the examination of dating violence typologies. Typological theoretical perspectives on partner violence and other antisocial behaviors posit the existence of different types or patterns of violence that have distinct causes and consequences and may thus merit different prevention and treatment approaches Holtzworth-Munroe and Stuart ; Johnson ; Johnson ; Langhinrichsen-Rohling ; Moffitt For example, Johnson ; proposed a typology of partner violence among adults distinguishing a pattern of violence termed intimate terrorism , which is characterized by the use of severe emotional and physical violence to dominate and control a romantic partner, from situational violence , which is less severe, reciprocal, occurs with less frequency, and is not embedded in a dynamic of coercive control.
While these and other for a review, see Johnson and Ferraro proposed typologies vary in many particulars, they all suggest there may be subgroup heterogeneity in the causes, manifestation, and consequences of partner violence that could limit the effectiveness of one-size-fits-all prevention programs. This new emerging body of research has used person-centered analytic approaches e. For example, two previous studies have used person-centered approaches to assess adolescent dating violence profiles using measures of both victimization experiences as well as perpetration behaviors Haynie et al.

About Follow Donate. Among Republicans, Gen Z stands out in views on race, climate and the role of government. No longer the new kids on the block, Millennials have moved firmly into their 20s and 30s, and a new generation is coming into focus. In most cases, members of the Silent Generation are at the opposite end, and Baby Boomers and Gen Xers fall in between. Most have yet to reach voting age, and their outlook could be altered considerably by changing national conditions, world events or technological innovations.
Even so, two new Pew Research Center surveys, one of U. Similarly, while majorities in Gen Z and the Millennial generation say government should do more to solve problems, rather than that government is doing too many things better left to businesses and individuals, Gen Xers and Boomers are more evenly divided on this issue. For their part, most Silents would like to see a less activist government. When it comes to views on race, the two younger generations are more likely than older generations to say that blacks are treated less fairly than whites in the United States today.
