A lonely man is a strong man


Social support definition

Social support - definition

  • Social support is the resource provided by other people (S Cohen, L Syme 1985)

  • Social networks - structure

  • Social supports - function

  • Social relations may have negative and positive effects on health


Social networks and health

Social networks and health

”the patterns of prospective association between social integration (that is the number and frequency of social relationships and contacts) and mortality are remarkably similar, with some variations by race, sex and geographic locale.”

House et al., Science, 1988

Swedish survey of living conditions

Swedish Survey of Living Conditions

  • 17 400 men and women, age 15 to 65

  • Representative of the Swedish population

  • Followed for 6 years

  • Low Social network interaction predicted mortality in men of all ages

  • Excess risk 50%, controlling for other risk factors


Men aged 50 born in g teborg

Men, aged 50, born in Göteborg

  • 741 men, born in 1933

  • Followed for 6 years and 15 years

  • Attachment - close emotional ties

  • Social integration - help with appraisal and coping, tangible support, belonging


Social inegration avsi

Social inegration (AVSI)

  • How many people do you know?

  • How many people do you have regular contact with?

  • How many friends do you have who can come to visit any time?

  • How many people can you trust?

  • How many people can you ask for small favors?

  • How many people can you turn to in difficulties and expect real help?

Attachment avat

Attachment (AVAT)

  • Is there anyone you can lean on?

  • Is there anyone who feels very close to you?

  • Is there anyone you can share happiness with, who would also feel happy ?

  • Is there anyone you can share most private feelings with ?

  • Is there anyone to hold and comfort you?

  • Do people really appreciate what you do for them?

Conclusions

Conclusions

  • Socially integrated men have half the risk of getting a myocardial infarction over 15 yrs

  • Attachment is also protective

  • Both effects are independent of other risk factors

Social support

Attachment did not significantly affect prognosis in women.Are close emotional ties stressful rather than protective in women?

Negative effects of social ties?


Social support

Aim

To evaluate the impact of stress from social relations on prognosis in women CHD patients - controlling for both disease severity, standard risk factors and work stress as measured at baseline.


The stockholm marital stress scale

The Stockholm Marital Stress Scale

Is the relationship with your spouse loving?

Is the relationship with your spouse friendly?

Is the relationship with your spouse routine-like ?

Is the relationship with your spouse problematic?

Do you engage in leisure activities together with your spouse?

Do you have your own private life outside the relationship with your spouse?

Is your spouse your closest confidant?

Are there things you can’t talk openly about with each other?

Have you had serious problems in the relationship with your spouse previously?

Have you had serious problems in the relationship with your spouse currently?

Have you had serious crises in your relationhip?

Have you solved problems actively together?

Do you have a sexual relationship with your spouse?

Do you find the sexual relationship with your spouse satisfactory?

Has your sexual relationship been affected by your heart disease?

IS THE MEATABOLIC SYNDROME A MEDIATING MECHANISM?


The metabolic syndrome

The metabolic syndrome

  • Defined according to WHO

  • Fasting plasma glucose > 7.0 mmol/l

  • Blood pressure > 160/90 mmHg

  • Central obesity ( w/h >.85 or BMI>30 kg/m2)

  • Fasting TG >1.7mmol/l or HDL<1.0 mmol/l

Methods

Methods

  • All female patients, aged 65 or under who wereadmitted with an acute coronary syndrome between 1991 and 1994 in Stockholm (n=292)

  • Diagnosis at baseline: Acute Myocardial Infarction (n=110) or unstable Angina Pectoris (n=182)

  • followed for five years for recurrent event

  • sleep complaints were measured at baseline using a standardized questionnaire

  • 283 women answered the sleep questionnaire


The sleep questionnaire

The Sleep Questionnaire

  • Have you perceived any of the following

  • complaints during the last time?

  • Difficulties falling asleep

  • Disturbed/restless sleep Sleep quality

  • Premature awaking index

  • Heavy snoring

  • Not feeling refreshed

Results

Results

Poor sleep quality and not feeling well-rested are associated with poorer prognosis in women with a prior cardiac event.


Are variations in heart rate and rhythm autonomic imbalance a mediating mechanism

Are variations in heart rate and rhythm - autonomic imbalance a mediating mechanism?


Heart rate variability

HEART RATE VARIABILITY

Derived from 24-hour Holter recordings:

SDNN index Total power

Low Frequency power (LF)

High Frequency power (HF)

Very Low Frequency power (VLF)

SDNN index:

average of the standard deviations of all normal to normal

intervals for each 5-minute interval of the entire recording

(ms)


Hrv high healthy low unhealthy

HRV - high (healthy)low (unhealthy)

Heart rate variability =

ability ofthe heart to react to stressors
