Usage and users of natural remedies in a middle-aged population: demographic and psychosocial characteristics. Results from the Malmö Diet and Cancer Study.

BACKGROUND: In Sweden, large amounts of money are spent annually on natural remedies (NRs), in spite of the fact that most products in this category lack scientific documentation of their efficacy and side-effects. The usage and users of natural remedies are not well defined. This paper describes NR use and NR users in a city in southern Sweden, and tests the hypothesis that the use of natural remedies is a strategy for coping with psychosocial stressors. METHODS: The study cohort consisted of 6545 men and women, aged 45-65 years, who during 1991 and 1992 participated in the Malmö Diet and Cancer Study, a large-scale prospective cohort study. Data on consumption of natural remedies were recorded during seven consecutive days, as part of a dietary assessment. Each participant also completed a questionnaire, covering education, work history, alcohol and smoking habits, perceived health, and psychosocial factors such as social network, social support, job strain and global control. Body composition was also measured. RESULTS: The prevalence of NR consumption was 26% among women and 17% among men. NR use was most common during winter and spring. The most popular products were ginseng, garlic, and various herb and plant extracts. Important determinants of NR usage were higher education, Swedish origin, and lifestyle factors like low body weight fat percentage and high alcohol consumption among women. Other determinants were higher age and non-smoking among men. None of the psychosocial factors appeared to influence the prevalence of NR consumption. CONCLUSIONS: The prevalence of NR consumption is influenced by sex, demographic factors, season of the year, and lifestyle. Use of NRs does not appear to be a common strategy for coping with psychosocial stress.

Increased risk of ischaemic heart disease mortality in elderly men using anxiolytics-hypnotics and analgesics. Results of the 10-year follow-up of the prospective population study "Men born in 1914", Malmo, Sweden.

OBJECTIVES: An increased risk of all-cause and cardiovascular mortality in users of anxiolytic-hypnotic drugs (AHD) has been reported, and use of analgesics may be an additional factor. Therefore, we examined the association of AHD and analgesic use, alone and in combination, with all-cause and ischaemic heart disease (IHD) mortality. METHODS: Multivariate 10-year survival analysis in a population based cohort of 500 men born in 1914. Relative risks (RR) were adjusted by relevant confounders (blood pressure, serum cholesterol, diabetes mellitus, smoking habit, high alcohol consumption, history of previous IHD, cancer, and other diseases). RESULTS: The RR of both all-cause and IHD mortality were significantly increased among those using both AHD and analgesics compared to those who took neither of these drugs: RR = 1.8 for all-cause mortality, and RR = 2.7 for IHD mortality. CONCLUSION: Although the number of cases was small, warranting interpretative caution, the current study suggests that the combined use of AHD (mainly benzodiazepines) and analgesics seems to be associated with an increase in all-cause and IHD mortality in elderly men.

An economic and sociological interpretation of social differences in health-related behaviour: an encounter as a guide to social epidemiology.

We argue that the group-centred analyses of social epidemiology should follow from theoretical considerations that take the situation of the individual as their natural starting point. In a tentative dialogue between economics and sociology, we develop a framework for the analysis of health-related behaviour. Such behaviour is modelled as a process of decision-making at the individual level. Within economics, we draw specifically on the demand-for-health literature and the new institutional economics. Within sociology, Bourdieu's habitus theory is presented in combination with a macro-structural approach where the focus is on the process of individualization. The relationship between these different approaches to health-related behaviour and their implications is discussed. We find that the encounter between different sciences provides valuable insights for future work in the socio-epidemiological tradition.

Psychosocial resources and persistent smoking in early pregnancy--a population study of women in their first pregnancy in Sweden.

STUDY OBJECTIVE: To test the stress hypothesis by characterising women during their first pregnancy who continue to smoke in early pregnancy in comparison with women who quit smoking, with special reference to psychosocial factors like social network, social support, demands, and control in work and daily life. DESIGN: The study is based on a cohort of primigravidas followed during pregnancy. Data were collected by self administered questionnaires during the pregnant womens' first antenatal visit at about 12 weeks. SETTING: The study was performed in the antenatal clinics in the city of Malmö, Sweden. PARTICIPANTS: The participants were all primigravidas living in the city of Malmö, Sweden, over a one year period, 1991-92. A total of 872 (87.7%) of the 994 invited women agreed to participate. The population of this study on smoking includes all primigravidas who at the time of conception were smoking (n = 404, 46.3%). MAIN RESULTS: At the first antenatal visit (63.6% (n = 257) of the prepregnancy smokers were still smoking (a total smoking prevalence of 29.5%). The pregnant smokers were on average younger and had a lower educational level. The highest relative risk (RR) of continued smoking was found among unmarried women RR 2.7 (95% confidence interval) (1.5, 4.8), women having unplanned pregnancies RR 2.2 (1.2, 4.0) and those with a low social participation RR 1.6 (1.0, 2.7), low instrumental support RR 2.6 (1.2, 6.0), low support from the child's father RR 2.1 (1.0, 4.2) and those exposed to job strain RR = 2.3 (1.1, 4.8). The associations were independent of potential confounders such as age, educational level, nationality, cohabiting status, passive smoking, and previous years of smoking. CONCLUSIONS: This study supports the stress hypothesis. Smoking can be one way women handle stress when demands become too great. In order to reduce smoking among pregnant women, maternity centre resources need to be focused more on women with low psychosocial resources who are at highest risk for continued smoking. It is also important to involve actively the woman's partner or other important people in the woman's social network.

Importance of participation rate in sampling of data in population based studies, with special reference to bone mass in Sweden.

OBJECTIVE: To study the effects of participation rate in sampling on "normative" bone mass data. DESIGN: This was a comparison between two randomly selected samples from the same population. The participation rates in the two samples were 61.9% and 83.6%. Measurements were made of bone mass at different skeletal sites and of muscle strength, as well as an assessment of physical activity. SETTING: Malmö, Sweden. SUBJECTS: There were 230 subjects (117 men, 113 women), aged 21 to 42 years. RESULTS: Many subjects participated in both studies (163). Those who took part only in the study with the higher participation rate (67) almost invariably had higher values for bone mass density at the sites measured (up to 7.6% for men) than participants in the study with the lower participation rate. No differences in muscle strength were recorded. CONCLUSION: A high degree of compliance is important to achieve a reliable result in determining normal values in population based studies.

Alcohol consumption modifies the total lung capacity in smokers.

Smoking-related airflow obstruction can develop with or without emphysema. Moderate alcohol consumption has been suggested to diminish the risk of centrilobular emphysema caused by smoking. Our aim was to study the influence of total energy and nutrient (protein, fat, carbohydrate and alcohol) intake on smoking-related emphysema. Lung function and nutrient intake including alcohol consumption were recorded at age of 68 years in 478 men as part of the population study 'Men Born in 1914' in Malmö, Sweden. In nonsmokers (n = 88) and ex-smokers (n = 223), there were no significant relationships between energy and nutrient intake and lung function. In smokers (n = 167), men in the highest and lowest quintile of total lung capacity (TLC) differed in alcohol intake (p = 0.004) but not in intake of total energy or other nutrients. In smokers with a forced expiratory volume in 1 s/vital capacity ratio of below 70% (n = 81), alcohol intake was positively correlated with TLC (r = 0.31; p = 0.006) after adjustment for smoking and body mass index. We conclude that in men with smoking-related airway obstruction, emphysema defined as large TLC was associated with high alcohol consumption but not with the intake of total energy or other nutrients.

Dental considerations for a Glanzmann's thrombasthenia patient: case report.

Glanzmann's thrombasthenia is a qualitative platelet disorder characterized by a deficiency in the platelet membrane glycoproteins (GP) IIb-IIIa. It belongs to a group of hereditary platelet disorders typified by normal platelet numbers and a prolonged bleeding time. The bleeding seen in Glanzmann's thrombasthenia usually includes bruising, epistaxis, gingival hemorrhage, and menorrhagia. Spontaneous, unprovoked bleeding is unusual. The severity of bleeding is unpredictable in thrombasthenia and does not correlate with the severity of the platelet GP IIb-IIIa abnormality. The present case report describes the dental treatment of a patient with Glanzmann's thrombasthenia. A 39-year-old female with a history of Glanzmann's thrombasthenia presented for periodontal therapy for spontaneous gingival hemorrhage. The patient had been sporadically seen in the past and had a record of only returning for appointments on an "emergency" basis. The periodontal findings revealed a diagnosis of moderate to advanced adult periodontitis in all quadrants. After all dental options had been discussed, the treatment of choice was determined to be extraction of the remaining dentition and fabrication of immediate dentures. The patient received a loading dose of 5 grams of aminocaproic acid (EACA) intravenously 3 hours prior to the surgery. At the beginning of the extractions 1 gram of EACA per hour continuous infusion and a 6 pack of platelets was administered. The patient tolerated the extractions well. All sites healed normally. The patient has had no difficulty in adjusting to the dentures. The case report discusses a possible treatment option in a noncompliant patient having Glanzmann's thrombasthenia and briefly discusses other hereditary bleeding disorders with similar presentations.

Social network, social support and the prevalence of neck and low back pain after retirement. A population study of men born in 1914 in Malmö, Sweden.

In this study we investigated the importance of social network and social support systems outside the workplace and workload and psychological job strain in former work for the prevalence of daily neck and low back pain. The study population (n = 621) comprised a random half of all male residents in Malmö, Sweden, born in 1914, of whom 500 (80.5%) participated. Two of the social network and social support indices (social anchorage and availability of material and informational support) were independent of life-style factors (leisure time physical activity, smoking and alcohol consumption) related to daily neck and back pain after retirement (OR = 2.0, 95% CI 1.2-3.4 and OR = 1.7, 95% CI 1.0-2.7, respectively), while the psycho-social and physical factors in former work were not. As no conclusion about the direction of the association can be drawn, prospective studies are needed to further explore these findings.

The effects of intracanal medicaments, fillers, and sealers on the attachment of human gingival fibroblasts to an exposed dentin surface free of a smear layer.

To date there has been very little research into the possible effects of endodontic therapy on regeneration of the lost periodontal attachment. The objective of this study was to examine the effects of endodontic medicaments on fibroblast attachment to dentin surfaces free of a smear layer. Pulp chambers of extracted third molars were filled with one of the following medicaments: gutta-percha with Roth's zinc oxide and eugenol-based sealer, warm gutta-percha with sealer, warm gutta-percha without sealer, calcium hydroxide, formocresol, cotton pellet, or left empty. A predetermined dentin surface area was then inoculated with human gingival fibroblasts at a concentration of 2 x 10(4) cells per ml. The cells were allowed to adhere to the dentin surface for either 4 or 24 hours, then cell attachment was quantified using a methyl-tetrazolium assay. The data were analyzed using a Kruskal-Wallis one-way analysis of variance and Dunn's multiple comparison test. It was determined that fibroblast attachment was significantly reduced when exposed to formocresol or warm gutta-percha without sealer at both the 4 and 24 hour interval (P < or = 0.05). This suggests that the use of formocresol or warm gutta-percha without sealer in a root canal may impede periodontal wound healing and regeneration.

Social network, social support and heavy drinking in elderly men--a population study of men born in 1914, Malmö, Sweden.

We analysed whether there were associations among different aspects of social network and social support, on one hand, and heavy drinking and alcohol problems on the other. The study sample (n = 621) comprised a random half of all male residents born in 1914 in Malmö, Sweden. Five hundred (80.5%) participated. Heavy drinking was defined as an alcohol consumption above 250 g alcohol per week and alcohol problems were assessed by a modified Michigan Alcoholism Screening test. Eight conceptually differential aspects of social networks and social support were measured. Four of five social network indices (social anchorage, social participation, contact frequency, spousal support) were associated with heavy drinking (OR 1.9-2.5) and two social network indices (social anchorage, spousal support) were associated with alcohol problems (OR 2.1-2.3). The results in this study are independent of social class, but based on a cross-sectional study, so we do not know if heavy drinking has caused social isolation or the contrary. If these results can be verified in a prospective study, a strengthening of the social network of the individual could perhaps lead to more moderate alcohol habits and better health, a finding of potential importance in the field of health promotion.

Social network, social support and dental status in elderly Swedish men.

The objective of this study was to investigate whether there were associations between different aspects of social network and social support and dental status. The study sample (n = 621) comprised a random half of all male residents in Malmö, Sweden, born in 1914. Five hundred (80.5%) participated. Eight conceptually different aspects of social networks and social support were measured, and all men were clinically examined regarding number of teeth, prevalence of removable dentures, fixed bridges and anterior open tooth spaces. We found that some aspects of dental status were associated with social class, while others were associated with different aspects of social network and social support. Prevalence of complete dentures and fixed bridges was strongly associated with social class, a low number of functioning teeth was associated with both low social class belonging and an insufficient social network and social support, while anterior open tooth spaces were associated mostly with an insufficient social network and social support. This study shows that there are significant associations between some aspects of dental status and the social network and social support of the individual, while other aspects of dental status are associated with social class, which from a psychosocial perspective contribute to a deeper understanding of the backgrounds of dental status.

HIV infection: social network, social support, and CD4 lymphocyte values in infected homosexual men in Malmö, Sweden.

STUDY OBJECTIVE: The aim was to determine if there is an association between social network and social support and the CD4 cell count in HIV infected homosexual men. DESIGN: The study was cross sectional. A structured questionnaire assessing psychosocial factors such as social network and social support was administered at interview. Information on CD4 cell counts and HIV symptoms were obtained from participants' medical records. SETTING: The study population consisted of all HIV seropositive homosexual and bisexual men who had not been diagnosed as having AIDS seen at the Department of Infectious Diseases, the only hospital clinic in the city of Malmö (230,000 inhabitants), Sweden that provides care for HIV infected patients. PARTICIPANTS: Altogether 47 (68%) of 69 men in the population agreed to be interviewed. MAIN RESULTS: A low CD4 cell count was found more frequently in men with low social participation scores (OR 3.3; 95% CI 1.0, 11), in those with a low adequacy of social participation (OR 3.8; 95% CI 1.1, 13), and in men with low material support scores (OR 3.9; 95% CI 1.1, 13). After adjustment for age and time of awareness of the HIV infection, the two former associations remained statistically significant. CONCLUSIONS: These results, if reproduced in a longitudinal study, might suggest that psychosocial factors can affect an individual's immune system.

How much can data on days with heavy drinking decrease the underestimation of true alcohol consumption?

An adjusted quantity-frequency method, with questions on occasions with heavy drinking, was used to estimate the consumption of alcohol during the last 30 days. The purpose was to analyze if it was possible to decrease the underestimation of true alcohol consumption. The questionnaire was mailed to a randomized sample of 1,500 individuals, 20-75 years of age, living in the city of Malmö, Sweden; 930 persons (64.3%) participated. Data on alcohol consumption were validated by comparison to sales of alcohol for the city of Malmö. The estimated per capita consumption of alcohol in the population was equivalent to 77.0% of the registered sale of alcohol in Malmö. By adding days with heavy drinking, the estimated weekly per capita consumption of alcohol among the alcohol consumers increased from 74.5 grams to 77.1 grams (+3.5%; p < .001). Of the alcohol consumers, 15.1% increased their reported consumption. In order to decrease even more the underestimation of the true alcohol consumption, we suggest the use of questions about any alcohol consumption that deviates from the typical consumption of each individual.

Alcohol habits among teenagers in Sweden: factors of importance.

This study of 689 secondary school students (13-16 years of age) in Sweden investigates the association between alcohol habits, the availability of alcohol and age, gender, socioeconomic status, ethnic origin and family structure. Data were obtained by anonymous questionnaires in 1991. The availability of alcohol increased from the seventh grade to the ninth as did the proportion of alcohol consumers and students with regular alcohol consumption. Boys in the seventh and eighth grades showed somewhat more advanced alcohol habits than girls, but in the ninth grade the opposite was seen. Students with more advanced alcohol habits and a higher availability of alcohol more often belonged to a lower socioeconomic strata and they lived more often with a single parent. Students of foreign background drank alcohol (especially wine) more regularly. An association was also found between the parents' liberal attitude toward offering alcohol at home and frequent intoxication and the students' experience of illicitly produced liquor, especially among the youngest students. In spite of the Swedish alcohol policy the availability of alcohol is rather high among young people. Special attention in alcohol preventive work should be paid to girls, young people living with one parent, young people in lower socioeconomic groups and young people of foreign origin.

Serum concentrations of total sialic acid and sialoglycoproteins in relation to coronary heart disease risk markers.

This study investigated the relationship between serum sialic acid concentration and cardiovascular mortality. Correlations were determined between lifestyle-related coronary heart disease risk markers (cigarette consumption, alcohol consumption, and leisure time physical activity), biological risk markers (apolipoprotein A1, apolipoprotein B, lipoprotein(a), and diastolic blood pressure) on the one hand and the concentration of sialic acid as well as sialic acid-rich acute phase proteins (orosomucoid, haptoglobin, and alpha 1-antitrypsin) on the other. A total of 145 men aged 21-46 years and with a C-reactive protein concentration below 5 mg/l were included. Total sialic acid concentration correlated significantly with apolipoprotein B (r = 0.48), number of cigarettes smoked daily (r = 0.32), and leisure time physical activity (r = -0.23) after adjustment for age and other cardiovascular risk markers. No significant partial correlations were found between serum total sialic acid concentration on the one hand and alcohol consumption, apolipoprotein A1, lipoprotein(a), and diastolic blood pressure on the other. Of the sialic acid-rich glycoproteins, orosomucoid correlated with apolipoprotein B (r = 0.38), haptoglobin with cigarette consumption (r = 0.35) and leisure time physical activity (r = -0.26) and alpha 1-antitrypsin with cigarette consumption (r = 0.18), leisure time physical activity (r = 0.17), alcohol consumption (r = -0.18), and apolipoprotein B (r = 0.21) after adjustment for age and other cardiovascular risk markers.

Influence of social support on cardiac event rate in men with ischaemic type ST segment depression during ambulatory 24-h long-term ECG recording. The prospective population study 'Men born in 1914', Malmö, Sweden.

Three-hundred and ninety-four 68-year-old men, representing 60.3% of a cohort of men born in 1914, were examined with ambulatory ECG during 24 h in 1982-83. Ninety-eight (24.8%) men had one or more episodes of ischaemic type ST segment depression (greater than or equal to 0.10 mV), 79 of whom had no history of previous ischaemic heart disease (IHD). During 63 months follow-up, 17 of the 98 suffered a cardiac event, i.e. fatal or non-fatal myocardial infarction (MI) or death due to chronic IHD. The objective of this study was to assess the influence of psychosocial factors, such as social network and social support, on cardiac event rate in men with ischaemic ST segment depression. A higher risk was found among men with little material and informational support (i.e. access to practical services and material resources and access to guidance, advice and information (crude relative risk 4.8; 95% CI; 1.6-14.8) and men with low availability of emotional support (i.e. opportunity for care, encouragement of personal value and feelings of confidence and trust) (crude relative risk 4.3; 95% CI: 1.4-13.3). This association was independent of history of IHD and other known risk factors for myocardial infarction (MI).

The epidemiology of sick leave in an urban population in Malmö, Sweden.

The epidemiology of sick leave was studied in the city of Malmö, Sweden, (230,000 inhabitants). Every current and completed sick-leave episode during the year of 1985 was collected for 124,411 persons aged 16 to 65, who were registered with the National Health insurance scheme in 1985. Absence rate, absence incidence, absence prevalence and absence duration were analyzed in relation to age, sex, marital status, nationality, income and place of residence. Absence rate (mean value) in the total population was 25.5 days with a median of three days. The absence rate increased by age. High absence rates were seen for females, single people and some immigrant groups. This was even true for residential areas characterized by a higher proportion of single-person households and households on social welfare, of unemployed and people with a low income and a foreign background. The absence rate gives limited information as to the epidemiology of sick leave. Through adding absence incidence, absence prevalence and absence duration it was possible to get a more comprehensive picture of the phenomenon. Sex-differences in absence rate for instance were mainly explained by differences in absence incidence and prevalence, while differences in absence rate regarding nationality were explained by differences in absence duration. This is an important step towards a better understanding of the factors behind sick leave.
