Psychosocial Environment

Common Stressors

Stress, much like beauty, is in the eye of the beholder. What is stressful for one person may not be for another. However, there are some events and environments which typically cause stress:1

  • Changes to family: marriage, pregnancy, death, divorce, a new child
  • Work environment: job change, job loss, promotion, work overload, conflict at work, business failure, employee strike
  • Living environment: new house, relocation to a new community, loss of a home, neighborhood crime
  • Physical environment or conditions: noise, pollution, traffic, violence, illness, disability, injury, pain, cold, heat, lack of sleep, hunger, malnutrition, natural disaster, unsafe surroundings, physical abuse or neglect
  • Economic environment: poverty, escalating bills, unanticipated expenses, theft
  • Social environment: isolation, family or peer demands, forced separation (such as from military service, prison, abandonment or conflict), grief, emotional abuse or neglect, legal entanglements, bullying, difficult roommates or neighbors

Our psychosocial environment includes our responses to stressors in our lives, from temporary ones such as a traffic jam to major stressors such as war, homelessness or major disease. Our relationships with family members, friends, colleagues and other individuals and groups with whom we interact in our communities are an important part of this environment. These can impact our capacity to deal with stressors. Nurturing, supportive relationships allow us to better access all our innate resources to respond to stress in positive ways.2

Stress and the Body's Response

Our bodies, families, communities and lives are embedded in a complex network of systems. The degree of support in the environment can shape a person’s resilience. Likewise, an environment that is stressful can foster disease. The conditions of a person’s social and psychological environment—those in which they are born, grow, live, work and age—are known as the social determinants of health. These conditions are shaped by the distribution of money, power and resources at global, national and local levels.3

Risks for Stress: Riskscapes

A riskscape, or landscape of risks, captures the overlapping threats to health occurring in a physical location that increase risk for disease.4 An example of overlapping risks can be seen in impoverished neighborhoods,5 which often experience many of the stressors listed above simultaneously. We discuss poverty in more detail on our Socioeconomic Environment page.

Minority status, age and gender further interact to increase risk for disease.6 Individuals experience additional adversity when they live amid wealth and affluence but do not share those resources.7

Stressful Environments and the Social Ecological Model of Health

The rise of chronic disease is a complex and growing problem for public health in the US.8 Stress, particularly exposure to long-term chronic stress, is associated with the majority of chronic health conditions.9

Social Ecological Model of Health

The Social Ecological Model of Health Promotion (SEM) describes how our psychosocial experiences are nested inside layers that influence health and well-being:10

  • individual
  • interpersonal (familial)
  • communal (neighborhood)
  • societal

The Human Stress Response System

This response system is evolutionarily old and has been shaped by the environmental experiences of thousands of preceding generations. Through millennia of adverse environmental challenges, adaptations and collective evolution, humans have developed a sophisticated stress response system.11

The physical stress response is a complex network of coordinated physical and behavioral activations from the endocrine and nervous systems:12

When a threat is perceived, the hypothalamus activates the sympathetic nervous system (the "fight or flight" response) by sending signals through the autonomic nerves to the adrenal glands. The adrenal glands pump the hormone epinephrine—also known as adrenaline—into the bloodstream, causing several physiological changes:13

When the initial surge of epinephrine subsides, the hypothalamus activates the 1-5月佛山出口陶瓷产品同期下降4.6%, signaling the release of cortisol to keep the sympathetic nervous system engaged.

When the threat passes, the parasympathetic nervous system (the "rest and digest" function) calms the body and returns it to a pre-threat state.

The SEM is particularly useful in allowing researchers to study stressors from the micro scale (cellular) to the macro scale (social policy), positioning their work in the larger social ecological context.14 Layers are labeled with their corresponding social determinants of health.

Policies that affect economic and social determinants (top level) can decrease access to income and education, and have powerful effects on neighborhood stressors.15

These policies shape disparities in local environments (second level)16 such as poverty, pollution, crime rates and political power.

Daily opportunities (third level) create or suppress nurturing environments and govern the frequency and intensity of daily hassles (discrimination and microaggressions).17

These layers affect our daily behaviors and patterns (fourth level) and daily interactions.

As these pressures funnel down from the political to the community to the individual, they become observational cues (fifth level) that the environment is threatening, unpredictable or uncontrollable and thus stressful.18

Upon activation, the brain sends signals to the body to mount a stress response.19

Allostasis: The Body’s Stress Response

When the brain interprets a threat, it sends a cascading signal through the body that causes a stress response, known casually as "fight or flight" and more formally as an allostatic response.20 See The Human Stress Response System at right for more detail.

In healthy doses and supportive environments, this response is tempered and can foster learning.21 In adversarial environments the allostatic response can manifest as chest pain, heart palpitations, headaches, dysphagia (difficulty swallowing), intestinal cramping, anxiety, panic, immobility, frustration, muscle tension and inflammation.22

These reactions can be exhausting and imprint a strong memory of fear on the brain.23 Fortunately, a feedback system in the brain is capable of stopping the stress response. 24 Terminating the stress response and restoring the body to pre-stress response states is important to protecting the body’s long-term health.25

Programming the Stress Response

When early-life experiences signal that the environment is unpredictable, threatening or uncontrollable, the stress response system may be reprogrammed, becoming blunted,26 or may be programmed to be sensitized and thus more responsive.

Responsivity is informed by the number of steroid receptors available during stress termination.27 The feedback system in the brain—cells in the hippocampus—have glucocorticoid receptors that, once filled, signal the termination of the stress response. When there are fewer glucocorticoid receptors in these cells, it takes a higher circulating quantity of cortisol to terminate the stress response.

The number of receptors available in the feedback system is dependent on how many proteins are produced in that cell. This is determined by the availability of the receptor gene to be transcribed into proteins. Stress signals, such as cortisol, circulating in maternal blood during pregnancy, can epigenetically alter the glucocorticoid receptor gene to be permanently downregulated, causing fewer receptor proteins to be produced.28

How our bodies respond to stress varies across the population,29 determined by genetic predisposition30 and previous experiences including exposure to maternal stress signals before birth31 The typical responsivity can be modified by genetic predisposition32 but is generally neither amplified nor repressed.33 This neutral programming is optimal in moderately stressful environment where life is not overly threatening nor consistently safe. Over an individual’s life, neutral programming is optimal in balancing the risk for internal burnout from repetitive stress burden and survival in adverse environments long enough to maximize periods for mating and parenting.34

Chronic Stress and Disease: Weathering

With repeated exposure to stressors, the HPA axis activation is sustained, and stress signals continue to flood the body. This sustained activation delays the onset of restorative repair and pushes the body into pre-disease states.35 Chronic stress acts on the cardiovascular, metabolic, neuroendocrine and immune systems:36

Over time, stress deteriorates health and resilience. This process is referred to as weathering.37 Just as a flag that weathers many storms begins to fray, so too does the body when it experiences harsh environments of social inequity.38 The health outcomes are mental illness, chronic disease morbidity and premature death.39 In short, stress causes physical changes that impact our health and functioning.

The frequency, duration, intensity, source, target and proximity of stressors influence the extent of the stress response. The duration of response can increase an individual’s risk for physical and mental burnout. Stressors that are higher intensity or longer duration carry a high internal burden (allostatic load).40 Over time this internal pressure forces body systems to adapt in ways that foster pre-disease states.41

In weathering, each body system adapts to this internal pressure through secondary changes:42

Dysregulation in these areas  can cause these secondary changes.43   With chronic stress, such changes increase the risk for these conditions:44

  • Metabolism
  • Mental functioning

  • Increased startle response

Stress-induced Gene Expression

Physiologic shifts following stressful exposures occur in large part through hormone-activated gene expression.45 When cortisol is released by the adrenal glands into the blood stream, it targets glucocorticoid responsive genes in tissues distributed throughout the body,46 including the central nervous system, metabolism, immune, cardiovascular, endocrine and renal systems.47

Within each cell nucleus, the steroid hormone binds with its receptor, and this complex binds to a stretch of DNA called a hormone response element.48 This binding activates gene expression to shift the physiologic activity of the target cell. In this way, stressful experiences, mediated through the allostatic response, have an epigenetic effect on the body.

See our Gene-Environment Interaction page for further explanation.

Through this process, chronic stress responses cause weathering on the body, eroding health status.49 As years turn into decades, the physiologic changes (such as hypertension, metabolic disorder or anxiety) may become irreversible, often increasing co-morbidities, potentially increasing maladaptive coping mechanisms (such as social aversion, drug and alcohol dependence) and decreasing life expectancy.50

Through these mechanisms social structures can get under the skin, alter our bodies and cause disease. The loss of productivity and financial burden of systemic disease further erodes family and community resilience, especially when the chronic stress starts in childhood.51

Disadvantaged Populations

Lower social classes experience longer durations of chronic stress, such as lengthy unemployment or institutionalized discrimination. Those with less power experience barriers to achievement of life goals, such as high costs of educational programs or lack of childcare options, inadequate recognition and rewards for personal qualification (such as gender pay differences) or for invested effort in the workplace. In the US and other White-majority countries, minorities and women in these environments are exposed to more chronic stressors than their White male counterparts due to differential expectations resulting in role strain and interpersonal conflict.52

Both the sources and frequency of stressors are not distributed equally in society, with heavier burdens borne by those with less advantage.53 These systems of inequity create differences in health outcomes, known as health disparities.54

These exposures increased amygdala function, which enhances fear, anxiety, and emotional dysfunction, while it decreased prefrontal cortex function, which participates in regulating and terminating the stress response.55

Our stress system responds to environmental conditions even before birth56 and is especially sensitive early in development.57 Glucocorticoid receptors are found in most fetal tissue and in the placenta, suggesting they are capable of responding to high maternal cortisol. Early-life experiences shape our stress response and therefore the impact stress has on our health over the life course.

A person’s individual responsiveness to stress signals can shape brain development.58 Highly responsive individuals demonstrate better learning and health outcomes in supportive environments and worse health outcomes in high adversity environments.59 Supportive environments foster better mental and social learning, increase memory and improve decision-making; in such environments, children have adequate time for stress response termination and are generally characterized by openness to information.

In negative environments, however, high responsivity magnifies the body’s response to intense or chronic stressors, increasing the risk for weathering over the life span. Highly responsive individuals can become hypersensitive to social feedback and psychological manipulation, both capable of detracting individuals from achieving goals.60 This increases the risk for future stressful experiences, further increasing the risk for weathering.

cycle of stress and performance

Stress responsivity shapes the intensity of weathering and has implications for later adult health outcomes.61 Responsivity biased toward either under- or over-reactivity can predispose children to adult disease.62 For example, overexposure to maternal stress hormones before birth can restrict birth weight and predispose the developing child to hypertension later in life.63 Effects of parental stress, such as reduced opportunities for bonding and distant parent-child relationships, significantly increase the risk up to fourfold for a child to experience anxiety, depression, diabetes and heart disease as an adult.64 Higher prenatal glucocorticoid exposure is directly associated with higher circulating glucocorticoids in adulthood, and both are associated with increased hypertension and hyperglycemia and changes in adult behaviors.65

Investigating Brain Changes

We rely heavily on animal models to understand early-life stress programming because sampling a core of living human brain is not an option. However, we do have direct human associations: the brains of suicide completers show epigenetic changes in the glucocorticoid receptor gene66 as well as methylation changes in other important genes that inform the intensity of the stress response.67

Newborns of mothers with depressive symptoms during pregnancy also demonstrated increased methylation of the GR gene in umbilical cord blood cells. As three-month-old infants, these children had higher levels of salivary cortisol.68

Brain Changes

With exposure to chronic stress, the brain changes shape, reducing connections that support nuanced cognitive function, self-regulation and memory; this process is less reversible as a child ages. Through these changes, chronic stress increases the likelihood of aggression, vigilance and anxiety.69 Because an individual suffering from these changes and conditions is handicapped in becoming a nurturing parent (although many people do overcome adversity and become terrific parents), the effects of stress can be self-perpetuating down generations. Through stress biasing, the social determinants can become multigenerational stimulants of chronic disease.70

To the individual, there is a cost for high responsivity. Early life stressors that reshape the brain affect hippocampal and amygdala development that can affect a child’s transition into adolescence. Chronic early stress impacting social learning may predispose teens to depression and substance abuse, both feeding into adult chronic diseases.71 This is a vicious cycle of early childhood adversity. The stress that parents experience can have direct influences on a child’s biological capacity in responding to future stressful situations.72 The parent-child relationship, in utero and through development, provides experiential information that programs stress responsivity.

Telomere Changes

Telomeres are structures on the ends of chromosomes that protect and stabilize chromosomes. They are essential for avoiding cellular dysfunction. Telomere length is reduced with age, smoking and stress, and shorter telomeres can impair health.73

Telomere length in specific blood cells is viewed as a biomarker for cellular aging that is closely associated with age-related and chronic diseases.74 This biomarker may reflect population-level weathering in communities. For example, a study of nine-year-old boys found that adverse environments shaped by low income, low maternal education, unstable family structure and harsh parenting were associated with a 19 percent shortening of white blood cell telomeres as compared to a cohort in more nurturing environments. These boys physically aged faster than their chronical age would suggest. Children with the most sensitivity (highest responsivity) to stress showed the longest telomeres in advantaged environments and the shortest in disadvantaged environments.75

Resilience

Resilience, the capacity to recover quickly from difficulties, is a characteristic of both individuals and communities. Parental bonding is a resilience factor, protecting children from the adverse effects of poverty on emotional and cognitive development.76

Community resilience is difficult to define and measure; the US Department of Health & Human Services defines it as "the ability of a community to use its assets to strengthen public health and healthcare systems and to improve the community’s physical, behavioral, and social health to withstand, adapt to, and recover from adversity".77   A resilient community is one that is socially connected, takes collective action, and has access to necessary resources.

Substantial risks to community health and well-being lie within community adversities such as climate change, urbanization and disparities. In the context of a natural or manmade disaster, increasing community resilience includes better preparedness and disaster planning, promoting community systems, and reducing threats to health. These are some steps communities and public health can take to build resilience:78

Selected Sources of Stress and Impacts on Health

Psychosocial risk factors for disease include family conflict, neighborhood violence, work stress and social discrimination; these factors can hinder mental and physical health.82

Domestic and Intimate Partner Violence

Global Domestic and Intimate Partner Violence

Globally, most data available is on intimate partner violence and sexual assault against women. An estimated 35 percent of women worldwide have experienced intimate partner violence over their lifetimes. Violence rates range from 71 percent of all women in Ethiopia to 15 percent of all women in Japan. Worldwide, up to 38 percent of all murders of women are committed by their partners.83

Domestic and Intimate Partner Violence: United States

Domestic violence includes violence from spouses, partners, parents, children, siblings or relatives. Three-quarters of incidents occur against women.84 In fact, it is estimated that a US woman is assaulted or beaten every nine seconds.85

Types of Domestic Violence.86

  • Rape
  • Sexual assault
  • Robbery
  • Intimate partner assault

Most violence occurs around the home (77 percent),87 and 19 percent of all violent incidents include the use of a weapon.88

The 楼市急转直下 买房人该怎么选? shows that between 2003 and 2012, domestic violence accounted for 21 percent of all violent victimizations in the US, with 70 percent of those from intimate partner violence (IPV).89

Preventing Violence in Relationships

Research in high-income areas indicates school-based programs can help prevent relationship violence among young people.91

Costs. Intimate partner violence accounted for $4 billion annually in 1995 in health care services and an additional $900 million in lost productivity.92 When these amounts are updated to 2003 figures, $8.3 billion in annual expenses are estimated, a combination of higher medical costs ($5.8 billion) and lost productivity ($2.5 billion).93

Health outcomes of intimate partner violence. In addition to death and injury (bruising, flesh wounds, fractures, brain injury and headaches), the cardiovascular, gastrointestinal, immune, and endocrine systems are impacted from violence-induced stress, as discussed above.

Neighborhood Violence

Living in a neighborhood that experiences high levels of violence can have a devastating impact on people’s long-term mental and physical health.  People who live in neighborhoods with high rates of violence suffer from trauma-related illnesses such as post-traumatic stress disorder (PTSD), at higher rates.101

child memorial in a poor neighborhood

时间:2009-10-26 编辑:vicki

Exposure to neighborhood violence is especially harmful for children—it has been shown to impair children’s cognitive abilities and academic performance, and potentially contribute to inattentive and compulsive behaviors.102

Other health outcomes are associated with negative characteristics of residential settings including fewer cancer screenings, cardiovascular disease, and the outcomes of violence discussed above. The risk or resilience of a community can directly affect the prevalence of child maltreatment.103

A 2015 review of national and international studies in urban areas found these associations. More research is needed in rural areas to understand if these factors are generalizable:104

  • In the US community unemployment rate, per capita income, poverty rate and educational status were associated with intimate partner violence.
  • Internationally, though lacking representation from Europe or the Middle East, intimate partner violence was associated with community norms, community attitudes towards women, women’s literacy, education, and murder rates. Women’s empowerment is also shown to be protective against IPV.
  • Households with higher proportions of children were also associated with an increased risk of IPV.
  • Community characteristics such as lower collective efficacy, social cohesion, higher perceived neighborhood disorder, and general social disorganization are associated with an increase of IPV. Although crime and violence rates themselves have mixed results with association to IPV, higher levels of perceived violence and worry about violence are associated with IPV.

Discrimination

Racism, sexism, and other forms of discrimination exert a negative influence on mental health in a variety of ways. While experiencing discrimination within a person’s community is deeply stressful in and of itself, discrimination can also place certain groups at a higher risk of other adversities (poverty, segregation, unemployment, violence), which can also negatively impact health. Systematic racism, for example, raises exposure of communities of color to social exclusion and economic adversity, thereby placing them at a higher risk of stress, anxiety and chronic disease.105

Work Stress

Many factors in a person’s workplace can have a negative impact on their mental well-being. Factors such as poor work satisfaction, high demand, low job security, harassment and work disorganization can all cause people to feel substantially stressed while on the job. A 2016 investigation found 43 percent of working adults said their job negatively affects their stress levels. Others said their job negatively affects their eating habits (28 percent), sleeping habits (27 percent) and weight (22 percent).106

One reason stress is a such a risk factor for substance abuse is that substance abuse can temporarily reduce anxiety caused by stressful events. As stress levels become chronic, the body responds with dysregulated hormonal states and stress-related behaviors that can produce anxiety. This predisposes an individual to seek substances that temporarily alleviate this stress-induced physical state. After the 9/11 terrorist event in the US, researchers noted a corresponding increase in the sales of various street drugs.111

Those who drink alcohol report that doing so makes them feel relaxed and less stressed. However, using alcohol as a coping mechanism for stress, especially on a regular basis, increases alcohol's harm to the body.

Stress and Antisocial or Violent Behavior

Stressors early in life are heavily associated with aggressive tendencies later in adulthood.112 Universally, childhood maltreatment is a risk factor for conduct disorders, antisocial personality symptoms, and becoming a violent offender. Research has found that abused boys experiencing erratic, coercive and punitive parenting were most at risk of antisocial behaviors later in adulthood, with the earlier the experience the more likely the negative behaviors were. Early child abuse doubles the risk a person will engage in criminal activities later in life.113

Environments That Break the Cycle of Violence114

  • 建设行业智库 促进建材工业绿色发展

  • Gisele, 37, came in second place, having earned $17.5 million, marking the first year she has not headed up the line-up since 2002.

This "cycle of violence" describes the association between experiencing violence during childhood and the increased risk of either becoming violent or being a victim of violence. Although the majority of maltreated do not grow up to abuse others, we do know that one in six maltreated children becomes a violent offender and one in eight sexually abused boys becomes a sex offender.115 Victims of childhood abuse are at an increased risk of abusing their own children. Researchers also have found that up to one in seven children who experienced maltreatment in childhood also experienced abuse by their spouse. Violent experiences can be collective (gang membership), self-directed (harming oneself) or interpersonal (by a parent or other).116
