Job strain and mortality in elderly men: social network, support, and influence as buffers.

The aim was to investigate whether job strain affects mortality in a representative population of elderly men, and whether social network and social support outside the workplace can buffer the negative health effects of job strain. A higher relative mortality risk (RR) was found among men exposed to job strain (RR = 1.7). The combination of exposure to job strain and seven different measures of weak social network and social support was associated with a further increased RR ranging from 2.1 to 4.6.

Social network, social support and acute chest complaints among young and middle-aged patients in an emergency department--a case-control study.

The risk of developing non-specific chest complaints was higher among young and middle-aged persons with a weak social network and low social support, when comparing cases with controls at a hospital emergency department (ED). The study was comprised of 62 cases; two different control groups were recruited from other patients at the medical ED (n = 67) and from patients at the surgical ED with urolithiasis or cholecystitis (n = 31). Relative risks for non-specific chest complaints were 2.3-3.4 for patients with a low score on two of the social network factors (an overall index and social anchorage) and two social support factors (emotional esteem support and support by a confidant). These results could be used for developing guidelines for a more adequate clinical management of these patients, as well as for the prevention of stress-related conditions in general. An analysis was made of the conceptual validity of the instrument used for assessing social network and social support. It was concluded that structural elements, such as social network factors, represented a more valid measurement that was less affected by subjectivity. Future research is of importance for finding overbridging concepts, rather than to further continue the dissection of presently used indices into even more 'specific' variables.

Risk factors for carotid artery stenosis: an epidemiological study of men aged 69 years.

Four hundred and seventy-eight men born in 1914 and residing in the city of Malmö, Sweden, underwent ultrasonic Doppler examination of the carotid arteries in 1982/83. The known risk factors for vascular disease--blood pressure, lipids, glucose, hematocrit, alcohol consumption and Body Mass Index were also measured. A moderate stenosis (diameter reduction 30-59%) of the internal carotid artery was found in 95 men (20%); 15 men (3%) had a greater than or equal to 60% stenosis of the internal carotid artery, while 7 (1.5%) had complete unilateral occlusion. Smoking was found to be significantly related to severe carotid artery disease. There was also a significant correlation between maximum flow velocity in the internal carotid artery and triglycerides. Those quitting smoking before the age of 50 had the same incidence of internal carotid artery disease as non-smokers, while those quitting later in life had a slightly higher incidence than life-long smokers.

Social network and social support predict improvement of physical working capacity in rehabilitation of patients with first myocardial infarction.

A cohort of 50 patients under 70 years of age who had suffered their first myocardial infarction (MI) entered an exercise-based rehabilitation programme. An extensive personal interview concerning psychosocial factors, including social network and social support, as well as an assessment of an array of clinical and laboratory variables was made before the patients were discharged from the hospital. A follow-up 6 months later of the 40 patients that completed the programme showed that material social support and social anchorage at baseline predicted improvement in physical working capacity, independently from age, gender and important clinical variables. The authors conclude that psychosocial factors could be predictors of equal importance as many of the standard risk factors and clinical assessments in the rehabilitation of a majority of post-MI patients. It is suggested that training programmes should provide opportunities for involvement of the patients' social network, in order to benefit from optimal social support during the rehabilitation process.

Social support and quitting smoking for good. Is there an association? Results from the population study, "Men born in 1914," Malmö, Sweden.

The objective in this study was to analyse whether there is independent association between social network, social support, social influence and quitting smoking for good. The study sample (n = 621) comprised a random half of all male Malmö residents born in 1914, of which 500 (80.5%) participated. A new instrument based on a model with carefully defined and well differentiated concepts was used to measure different aspects of social network, social support and social influence. In logistic regression analysis, emotional support (an important aspect of social support) had an association to quitting smoking for good (odds ratio 3.1, 95% confidence interval 1.9-5.4), when adjustments were made for social class, marital status (spousal support), alcohol consumption, physical activity, smoking of spouse and different medical conditions. Emotional support reflects the individuals' opportunity for care, encouragement of personal value and feelings of confidence and trust. This may contribute to a deeper understanding of mechanisms behind smoking cessation and could be of importance in the field of health promotion, but also for improvement of the long-term results of smoking cessation programs and in our clinical work with patients who smoke.

Social network and social support influence mortality in elderly men. The prospective population study of "Men born in 1914," Malmö, Sweden.

The objective of this study was to determine whether there is an association of all-cause mortality with different aspects of social network, social support, and social influence. The study sample (n = 621) was a random half of all male residents of Malmö, Sweden, born in 1914, of whom 500 (80.5%) were interviewed and examined in 1982-1983. On the basis of a model with carefully defined and well-differentiated concepts integrated in a theoretic framework of social resources, an instrument was developed to measure different aspects of social network, social support, and social influence. During the follow-up period from September 1982 to November 1987, 67 (13.4%) of the 500 participants died. In univariate analysis, a higher mortality risk was found among men with low availability of emotional support and low adequacy of social participation and among men living alone (crude relative risk = 2.3, 2.3, and 1.7, respectively). These relative mortality risks changed little after adjustments for social class, health status at baseline, cardiovascular risk factors, alcohol intake, physical activity, and body mass index in the multivariate analysis (adjusted relative mortality risk = 2.5, 2.2, and 2.0 for men with low availability of social support and low adequacy of social participation and for men living alone, respectively). These findings are consistent with the existence of a general effect of social network and social support on mortality among elderly men.

Increased mortality in men with ST segment depression during 24 h ambulatory long-term ECG recording. Results from prospective population study 'Men born in 1914', from Malmö, Sweden.

'Men born in 1914', from Malmö, Sweden, is a cohort study of the morbidity and mortality of cardiovascular diseases among 68-year-old men in an urban population. Ambulatory long-term ECG recording was part of the health examination that these men were invited to undergo in 1982. Five hundred attended (80.5%) of the 621 invited. Ninety-eight of the 394 men in whom the ECG recording was technically satisfactory had at least one episode with horizontal or downsloping ST segment depression greater than or equal to 0.1 mV. The median total duration of ST segment depression was 135 min. 90% of these episodes were not preceeded by any increase in heart rate. In only eight of the 47 men who reported an occurrence of chest symptoms during the recording period did ST segment depression and chest symptoms occur simultaneously. 43 months after the health examination, 33 (8.4%) men had died. The mortality in men without ST segment depression and without any history of coronary heart disease was 6.5%. The incidence of fatal and non-fatal myocardial infarction in men without ST depression greater than or equal to 0.1 mV and without a history of IHD was 2.3%. Men with ST depression greater than or equal to 0.1 mV in comparison with this group had a 4.4 times greater relative risk. The risk in men with both ST segment depression greater than or equal to 0.1 mV and history of coronary heart disease was 16.0 times greater. This study shows that asymptomatic ST segment depression is a frequent finding in elderly men. The occurrence of asymptomatic ST segment depression is associated with an increased cardiovascular mortality. This increased mortality is independent of a history compatible with angina pectoris or previous myocardial infarction.

Job demands, job decision latitude, job support, and social network factors as predictors of mortality in a Swedish pulp and paper company.

Three hundred and ninety one male employees aged 35-65 in a Swedish pulp and paper company were followed up for 22 years; 151 deaths were recorded by 31 December 1983. On the basis of data from 1961, indices for job decision latitude, job support, and other work related psychosocial factors were constructed as were five indices for non-work related social network factors. All indices were checked by life table analysis in respect of mortality. Job decision latitude and a combined index for job decision latitude and job support showed significant associations with mortality. These two indices were investigated by multivariate analysis with scale for evaluation of neuroticism and known somatic risk factors such as smoking, cholesterol, and systolic and diastolic blood pressure. Age, educational level, occupational status, physically heavy work, and general health state were also included in the multivariate analysis. Age, systolic blood pressure, the combined index for job decision latitude and job support, smoking, and neuroticism were shown to be independent predictors of mortality.

Social network and regular dental care utilisation in elderly men. Results from the population study "Men born in 1914", Malmö, Sweden.

In connection with an extensive examination of their health status, a representative sample of 68-year-old men (n = 621) in the city of Malmö, Sweden, were interviewed in detail regarding different aspects of the social network, social support and social influence of the individual, dental care utilisation and perceived dental health. 79% of the dentate and 7% of the edentulous subjects made regular dental visits. The most important reason for not visiting a dentist regularly was "no perceived need". Social class and different aspects of social network and social support were in univariate analyses associated with regular dental care. In the multivariate analysis, social anchorage and social participation, subconcepts of the social network, and social class showed independent associations with regular dental care. The addition of the social network and social support variables yielded a more differentiated and thereby a more valid picture of the determinants of regular dental care utilisation. These factors should therefore be considered when public health efforts to increase the number of elderly persons receiving regular dental care are made.

Social anchorage and blood pressure in elderly men--a population study.

The present study was designed to test the hypothesis that there is an independent association between the three concepts of psychosocial factors, social network, social support, social influence and blood pressure (see Materials and methods for definition). The study sample chosen (n = 621) comprised a randomly selected group of half the male residents of Malmö born in 1914, 500 (80.5%) of whom participated. A study based on a model with clearly defined criteria was used to measure the different aspects of social network, social support and social influence. In multiple regression analysis, social anchorage (a subconcept of social network) was shown to have an association with both systolic (P = 0.03) and diastolic blood pressure (P less than 0.001), when adjustments for social class, marital status, medication for hypertension, alcohol consumption, smoking habits, body mass index (BMI) and physical activity were made. Social anchorage is a concept on a structural level, that describes to what degree the individual belongs to and is anchored within formal and informal groups in society. As such, it may contribute to a deeper understanding of mechanisms behind high blood pressure and could thus be significant in the field of health promotion.

The effect of nicotine on the attachment of human fibroblasts to glass and human root surfaces in vitro.

This study examined the effect of nicotine on fibroblast attachment to glass and nondiseased human root surfaces. Human foreskin fibroblasts (HFF) were trypsinized, suspended in RPMI 1640 medium, and incubated with autoclaved human root sections and nicotine concentrations of zero (control), 25, 50, 100, 200, or 400 ng/ml. The root sections were examined for fibroblast attachment at 24, 48, and 72 hours by light microscopy and scanning electron microscopy (SEM). Additional trypsinized HFF were incubated on glass surfaces with the same concentrations of nicotine and examined at one week by light microscopy. HFF attached and grew on glass and root surfaces at all concentrations of nicotine. Controls on glass surfaces exhibited a normal monolayer of long spindle-shaped fibroblasts with a parallel alignment and minimal overlapping. Nicotine-treated HFF exhibited a haphazard arrangement with cell overlapping and vacuolization of the cytoplasm. Under SEM, the controls had smooth surfaces and appeared firmly attached to the root surface via (1) microvilli and filopodia on the cell boundaries and (2) short, branched, thin-to-medium width cytoplasmic processes with microvilli and filopodia on their boundaries. Few microvilli were noted on the control cell surfaces. HFF exposed to nicotine had microvilli and filopodia on the cell surfaces and long thin and long broad cytoplasmic processes with many microvilli and filopodia that projected away from the root surface. These findings suggest that the nature of fibroblast attachment to glass and root surfaces is altered by nicotine. A similar disturbance in fibroblast attachment may occur in humans who use nicotine-containing products, making them more susceptible to destruction of the periodontium and less responsive to new attachment after periodontal therapy.

Different social network and social support characteristics, nervous problems and insomnia: theoretical and methodological aspects on some results from the population study 'men born in 1914', Malmö, Sweden.

A representative sample of 68-year-old men in the Swedish city of Malmö, were interviewed in detail regarding their social network, social support and social influence as a part of an extensive examination of their health status. Emphasis in this paper is put on the definition and operationalization of different social network, social support and social influence characteristics included in a tentative model. The reliability and validity of the different social network, social support and social influence indices are analyzed and discussed. The relation between the different indices and marital status and social class are analyzed implying that men living alone and men in the lowest social class have the most insufficient social network, social support and social influence. The indices were then used in an analysis of nervous problems and insomnia. Social anchorage, social participation and contact frequency, all subconcepts of social network, had independent associations with mental health in this cross-sectional study. The addition of the social network, social support and social influence indices to social class and marital status gives a more differentiated and thereby a more valid picture of the association between the psychosocial environment and this type of mental health problems.

Dietary intake and psychosocial factors in 68-year-old men. A population study.

In a representative sample of 621 men aged 68 years 500 (80.5%) participated in a dietary history interview, and in an interview where social network and social support characteristics, marital status, and social class were assessed. Also included was a questionnaire on alcohol consumption and smoking habits, as well as weight and height measurements and an assessment of the men's physical activities. The purpose was to describe dietary habits and to characterize men with inadequate habits according to different psychosocial characteristics. Average intake of energy and nutrients was, in general, well above the recommended. However, the variation was wide. According to the definition used, about 20% were considered to have "inadequate" dietary habits. No proportional differences in social class and marital status were found among these men. However, those with sufficient social network and social support fared better. Overweight, obesity, low physical activity and high alcohol consumption were more common among the men with inadequate diets. Low social anchorage, low physical activity and high body mass index were independent risk indicators of inadequate dietary habits in this population.

Factors influencing participation in health surveys. Results from prospective population study 'Men born in 1914' in Malmö, Sweden.

Base line data together with data in public registers and a structured phone interview of 94 of the 121 non-attenders was used for an assessment of factors influencing participation in the prospective population study 'Men born in 1914' in Malmö, Sweden. The overall attendance rate was 80.5% but varied among areas in the city from 27% to 100%. The lower participation rate among single men remained, when correcting for social class, significant only for single men in social class III. Men who did not feel well and/or had been admitted to hospital during the last 12 months had a lower participation rate. A negative attitude towards health surveys in general was the most common reason for non-participation. The phone interview turned out to be a feasible method to reach non-attenders to assess whether the sample was representative of the population and to learn more about reasons for non-participation.

Changes in the effects of stimulation of locus coeruleus and nucleus raphe magnus following dorsal rhizotomy.

The effects of stimulating locus coeruleus (LC) and nucleus raphe magnus (NRM) on lumbar dorsal horn cells that had been denervated by dorsal rhizotomy were studied. Both LC and NRM stimulation inhibited the responses of dorsal horn cells from the side of the cord with intact dorsal roots. However, when cells from the side of the spinal cord that had had prior rhizotomies were studied, half of the units were shown to be activated by either LC or NRM stimulation.
