ABSTRACT
OBJECTIVES: The prevalence of dementia is growing rapidly worldwide. The early identification and treatment of cognitive decline could reduce the burden on the health care system. Our objective was to investigate whether factors measured at an examination at age 50 predict cognitive impairment (CI) 23 years later. MATERIALS & METHODS: In 1993 we enrolled a randomly selected sample of 798 men, 50 years of age, from the general population. They all underwent a physical examination, provided blood samples and filled out questionnaires addressing lifestyle and psychosocial factors. Cognitive testing was offered to all participants still alive in 2016, at age 73. RESULTS: A total of 333 men participated in the cognitive study, of which 80 (24.0%) performed at a level corresponding to mild cognitive impairment, and four (1.2%) at a level consistent with severe cognitive impairment. After the first step in the multivariable analysis, hypertension, heavy smoking, high intake of alcohol, financial stress, difficulty falling asleep, and cogwheel rigidity were associated with cognitive impairment. After further adjustment, only wide waist circumference measured in cm (OR 1.04, 95% CI 1.00-1.08, p = .04), leg pendulousness (OR 41.97, 95% CI 3.27-538.62, p = .004) and self-assessed hidden irritability (OR 2.18, 95% CI 1.10-4.32, p = .03) at baseline, remained as being associated with cognitive impairment 23 years later. CONCLUSIONS: Extrapyramidal symptoms such as leg pendulousness, at the age of 50, may be an indicator for very early identification of future cognitive decline.

OBJECTIVE: We aimed to assess the feasibility of a simple new fifteen-item FFQ as a tool for screening risk of poor dietary patterns in a healthy middle-aged population and to investigate how the results of the FFQ correlated with cardiovascular risk factors and socio-economic factors. DESIGN: A randomized population-based cross-sectional study. Metabolic measurements for cardiovascular risk factors and information about lifestyle were collected. A fifteen-item FFQ was created to obtain information about dietary patterns. From the FFQ, a healthy eating index was created with three dietary groups: good, average and poor. Multivariate logistic regression was used to assess relationships between dietary patterns and cardiovascular risk factors. SETTING: Sweden. SUBJECTS: Men and women aged 50 years and living in Gothenburg, Sweden. RESULTS: In total, 521 middle-aged adults (257 men, 264 women) were examined. With good dietary pattern as the reference, there was a gradient association of having obesity, hypertension and high serum TAG in those with average and poor dietary patterns. After adjustment for education and lifestyle factors, individuals with a poor dietary pattern still had significantly higher risk (OR; 95 % CI) of obesity (2·33; 1·10, 4·94), hypertension (2·73; 1·44, 5·20) and high serum TAG (2·62; 1·33, 5·14) compared with those with a good dietary pattern. CONCLUSIONS: Baseline data collected by a short FFQ can predict cardiovascular risk factors in middle-aged Swedish men and women. The FFQ could be a useful tool in health-care settings, when screening for risk of poor dietary patterns.

BACKGROUND: Unexplained chest pain (UCP) is a common reason for emergency hospital admission and generates considerable health-care costs for society. Even though prior research indicates that psychological problems and impaired quality of life are common among UCP patients, there is lack of knowledge comparing UCP patients with a reference group from the general population. The aim of this study was to analyse differences between men and women with UCP and a reference group in terms of psychosocial factors as depression, anxiety, stress, social interaction and health-related quality of life (HRQOL). METHODS: A self-administered questionnaire about psychosocial factors was completed by 127 men and 104 women with acute UCP admitted consecutively to the Emergency Department (ED) or as in-patients on a medical ward. A reference group from the general population, 490 men and 579 women, participants in the INTERGENE study and free of clinical heart disease, were selected. RESULTS: The UCP patients were more likely to be immigrants, have a sedentary lifestyle, report stress at work and have symptoms of depression and trait-anxiety compared with the reference group. After adjustment for differences in age, smoking, hypertension and diabetes, these factors were still significantly more common among patients with UCP. In a stepwise multivariate model with mutual adjustment for psychosocial factors, being an immigrant was associated with a more than twofold risk in both sexes. Stress at work was associated with an almost fourfold increase in risk among men, whereas there was no independent impact for women. In contrast, depression only emerged as an independent risk factor in women. Trait-anxiety and a low level of social interaction were not independently associated with risk in either men or women. Patients with UCP were two to five times more likely to have low scores for HRQOL. CONCLUSION: Both men and women with UCP had higher depression scores than referents, but an independent association was only found in women. Among men, perceived stress at work emerged as the only psychosocial variable significantly associated with UCP.

BACKGROUND: Random samples of 50-year-old men living in Gothenburg have been examined every 10th year since 1963 with a focus on cardiovascular risk factors. The aims of the study were to acquire up-to-date information about risk factors in the fifth cohort of 50-year-old men and women, to re-examine those who were 50 years of age in 1993, and to analyse the prevalence of the metabolic syndrome (MetSyn) using different definitions. METHODS: A random sample of men and women born in 1953 were examined in 2003-2004 for cardiovascular risk factors. Men born in 1943 and that participated in the examination in 1993 were also invited. Descriptive statistics were calculated. RESULTS: The participation rate among men and women born in 1953 was 60 and 67% respectively. Among men born in 1943, the participation rate was 87%. The prevalence of obesity was from 15 to 17% (body mass index, BMI >or= 30) in the three samples. The prevalence of known diabetes was 4% among the 50-year-old men and 6% among the 60-year-old men, and 2% among the women. Increased fasting plasma glucose varied substantially from 4 to 33% depending on cut-off level and gender. Mean cholesterol was 5.4 to 5.5 mmol/l. Smoking was more common among women aged 50 (26%) than among men aged 50 (22%) and 60 years (15%). The prevalence of the MetSyn varied with the definition used: from 10 to 15.8% among the women, from 16.1 to 26% among 50-year-old men, and from 19.9 to 35% among the 60-year-old men. Only 5% of the men and women had no risk factors. CONCLUSION: This study provides up-to-date information about the prevalence of cardiovascular risk factors and the MetSyn in middle-aged Swedish men and women. Different definitions of the MetSyn create confusion regarding which definition to use.

BACKGROUND: Despite a decline in mortality rates from cardiovascular disease (CVD) in the past few decades, the burden of CVD in a contemporary population remains inadequately addressed. Therefore, this study was aimed to investigate secular trends in mortality from coronary artery disease and all-cause mortality over 2 decades, by comparing 2 cohorts of men born 30 years apart and evaluate the prediction of the risk of CVD and all-cause death in a contemporary random sample of Swedish men. METHODS AND RESULTS: Two cohorts of randomly selected men born in 1913 (855 men) and 1943 (798 men) were first examined at age 50 in 1963 and 1993, respectively, and followed longitudinally over 21 years. All-cause mortality and coronary artery disease death were lower in 50- to 71-year-old men born in 1943 compared with those born in 1913, with unadjusted hazard ratios of 0.57 (0.45-0.71) and 0.34 (0.22-0.53), respectively. After adjustment for risk factors (smoking, serum cholesterol, hypertension, systolic blood pressure, diabetes mellitus, body mass index, and physical activity), the differences between the cohorts remained significant for coronary artery disease, hazard ratios 0.57 (0.34-0.94), P=0.029, but not for all-cause mortality hazard ratios 0.82 (0.62-1.07), P=0.14. However, the rate of CVD events during follow-up was still high (30.7%) for the men born in 1943. No statistically significant interaction by birth cohort in contribution of risk factors to death was found between 2 cohorts except physical inactivity. CONCLUSIONS: Despite a marked reduction in the rate of coronary artery disease death over the past 30 years, the burden of CVD events and all-cause mortality remains high. Therefore, intensified efforts to modify contributing risk factors are still required.

BACKGROUND: The beneficial effects of statins were unequivocally demonstrated in the Scandinavian Simvastatin Survival Study (4S) in 1994, leading to an increase in the use of lipid-lowering drugs. However, to what extent this translates into serum cholesterol levels in a real-life setting has not been systematically investigated. OBJECTIVE: To estimate secular trends from 1994 to 2002 in blood lipid levels among unselected younger patients after a first acute myocardial infarction (AMI). METHOD: Descriptive single centre study using consecutive data collection in 781 patients (aged <65 years) hospitalized with a first AMI during the period 1994-2002. RESULTS: From 1994-2002, the use of lipid-lowering drugs increased from 10% to 94% for men and from 23% to 90% for women. In 1994, the mean serum cholesterol levels were 6.53 mmol/l in men and 6.32 mmol/l in women, decreasing to 4.31 mmol/l and 5.13 mmol/l in men and women, respectively, in 2002. Still, only 56% of the men and 35% of the women had total serum cholesterol levels <4.5 mmol/l in 2002. CONCLUSION: Despite a marked increase in lipid-lowering drug treatment in which there was an increase from about 10% in 1994 to more than 90% in 2002, current target levels of <4.5 mmol/l for serum cholesterol were not achieved in a significant proportion of post-AMI patients.

Background During the past decades, declining trends in mean cholesterol levels and smoking have been observed in Western Europe, whereas obesity and a sedentary lifestyle have increased. Simultaneously, there has been a marked decrease in mortality from cardiovascular (CV) diseases. Methods The aim of the study was to determine whether these trends in CV risk factors continued over a period of 50 years. Six systematic or random population samples of 50-year-old men ( n = 3563) living in Gothenburg, Sweden, were investigated between 1963 and 2013. Results During the 50 years, mean body mass index (BMI) at 50 years of age increased by 2 kg/m2, from 24.8 kg/m2 in 1963 to 26.8 kg/m2 in 2013 ( p < 0.001). A decrease in systolic blood pressure of nearly 10 mmHg was observed from 1963 to 1993, but was not sustained through the past two decades. Mean serum cholesterol fell from 6.42 (SD 1.12) mmol/L to 5.34 (SD 0.97) mmol/L. The prevalence of smoking at 50 years of age decreased markedly from 56.1% in 1963 to 11.9% in 2013. The number of participants with a sedentary lifestyle during leisure time decreased until 1993, but has remained unchanged since. In 2013, 50-year-old men had a 6.9-times higher likelihood of lacking CV risk factors than 50-year-old men in 1963 (95% confidence interval (CI): 3.5-13.3, p < 0.001). The odds ratio for having four or more risk factors was only 0.13 (95% CI: 0.062-0.29, p < 0.001). Conclusion Despite increasing body weight, the total CV risk factor burden has decreased in 50-year-old men over the past 50 years.

BACKGROUND: The number of patients suffering from unexplained chest pain (UCP) is increasing. Intervention programmes are needed to reduce the chest pain and suffering experienced by these patients and effective preventive strategies are also required to reduce the incidence of these symptoms. The aim of this study was to describe general coping strategies in patients with UCP and examine the relationships between coping strategies, negative life events, sleep problems, physical activity, stress and chest pain intensity. METHOD: The sample consisted of 179 patients younger than 70 years of age, who were evaluated for chest pain at the emergency department daytime Monday through Friday and judged by a physician to have no organic cause for their chest pain. The study had a cross-sectional design. RESULTS: Emotive coping was related to chest pain intensity (r = 0.17, p = 0.02). Women used emotive coping to a greater extent than did men (p = 0.05). In the multivariate analysis was shown that physical activity decreased emotive coping (OR 0.13, p < 0.0001) while sex, age, sleep, mental strain at work and negative life events increased emotive coping. Twenty-seven percent of the patients had sleep problems 8 to 14 nights per month or more. Permanent stress at work during the last year was reported by 18% of the patients and stress at home by 7%. Thirty-five percent of the patients were worried often or almost all the time about being rushed at work and 23% were worried about being unable to keep up with their workload. Concerning total life events, 20% reported that a close relative had had a serious illness and 27% had reasons to be worried about a close relative. CONCLUSION: Our results indicated that patients with more intense UCP more often apply emotive coping in dealing with their pain. Given that emotive coping was also found to be related to disturbed sleep, negative life events, mental strain at work and physical activity, it may be of value to help these patients to both verbalise their emotions and to become cognizant of the influence of such factors on their pain experience.
ABSTRACT
Enhancing and assuring the quality of doctoral nursing programs is currently of major concern to promote growth in quality and quantity of research in nursing. The aims of the paper were to review the literature about evaluation of higher education with focus on doctoral programs in nursing, and to present a strategy to evaluate a doctoral nursing program. A search of literature in relevant databases was done using the keywords doctoral program, evaluation, nursing, program evaluation and higher education. From the review it is concluded that more systematic evaluations are necessary to guide the development of quality in nursing. Attention must be given to the curricula, competence in the faculty, the research activity and to the students' involvement in courses and research. Therefore, a strategy for evaluation should be ongoing, flexible, systematic and comprehensive. It should involve students, graduates, employers and faculty members in evaluation, include process and outcome data and give possibility for comparison to internal and external standards. The strategy developed aims to facilitate ongoing and future improvement of the doctoral nursing program. This process is dependent on a methodological pluralism of evaluation to detect what is of most weight for growth in the process of research and education.

OBJECTIVES: Global self-rated health (SRH) has become extensively used as an outcome measure in population health surveillance. The aim of this study was to analyse the effects of age and secular trend (year of investigation) on SRH. DESIGN: Prospective cohort study, using population-based data from eight ongoing cohort studies, with sampling performed between 1973 and 2003. SETTING: Sweden. PARTICIPANTS: 11 880 women and men, aged 25-99 years, providing 14 470 observations. PRIMARY OUTCOME MEASURE: Global SRH. RESULTS: In multiple ordinal logistic regression analyses, adjusted for the effects of covariates, there were independent effects of age (p<0.0001) and of year of investigation (p<0.0001) on SRH. In women the association was linear, showing lower levels of SRH with increased age, and more recent year of investigation. In men the association was curvilinear, and thus more complex. The final model explained 76.2% of the SRH variance in women and 74.5% of the variance in men. CONCLUSIONS: SRH was strongly and inversely associated with age in both sexes, after adjustment for other outcome-affecting variables. There was a strongly significant effect of year of investigation indicating a change in SRH, in women towards lower levels over calendar time, in men with fluctuations across time.
ABSTRACT
BACKGROUND: Population-based study of a random sample of 50-year-old men and women in Gothenburg, Sweden. OBJECTIVE: To examine the determinants of perceived health and the differences between 50-year-old men and women. METHODS: Men and women born in 1953 were examined between 2003 and 2004. Participation rate was 60% among the men and 67% among the women. Questionnaires were used, including one on perceived health that was ranked on a 7-point scale from 1 (excellent) to 7 (very poor). The participants' medical histories were obtained through a questionnaire, and risk factors were measured. RESULTS: Women generally perceived their health as poorer than men. Women experienced more symptoms than men, and most symptoms were more prevalent among women than men. Poor perceived health was strongly related to number of symptoms. In multivariable analyses 5 factors were related to perceived health in both men and women: working full or part time (women OR [odds ratio] = 0.3, men OR = 0.3) and physical activity (women OR = 0.6, men OR = 0.6) had a positive effect, whereas a low level of social activities (women OR = 1.9, men OR = 1.7), still feeling tired after normal hours of sleep (women OR = 4.5, men OR = 4.0), and feeling burned out during the past 12 months (women OR = 2.3, men OR = 3.0) had a negative effect on perceived health. CONCLUSIONS: Women perceive their health as "worse" in comparison with men. Perceived health is a multifaceted condition related to social circumstances, physical activity, various symptoms, and tiredness after normal hours of sleep both in women and men.

BACKGROUND: Little scientific attention has been paid to providing a comprehensive multidimensional description of chest pain in patients with unexplained chest pain. AIMS: The aims of the present study were: (1) to describe the symptom chest pain, including the dimensions of intensity, quality, duration and location in patients with unexplained chest pain (UCP); and (2) to identify similarities and differences in how patients with UCP and patients with ischemic heart disease (IHD) describe chest pain. METHOD: A descriptive, correlational and comparative design. Totally 208 consecutive UCP patients and 40 IHD patients below 70 years of age participated. Pain was assessed using the instrument Pain-O-Meter. RESULTS: The occurrence of chest pain was 79% (n=165) in UCP patients versus 60% (n=22) in the IHD patients (p=0.001). Patients with UCP reported greater pain intensity and used more sensory and affective words than IHD patients (p<0.01). Relationships between pain location and amount of body surface involved in the pain and pain intensity in both groups were found (p<0.001). CONCLUSIONS: Our results showed some defining characteristics of the UCP group, but the many similarities between the two groups in their experience of chest pain made it impossible to clearly differentiate the groups' pain profiles.

BACKGROUND: Unexplained chest pain is a frequent and increasingly common complaint among patients admitted to Emergency Departments. Previous studies have defined unexplained chest pain as non-cardiac or non-coronary artery disease, i.e. patients with other organic causes explaining the chest pain could be included. To increase the knowledge of unexplained chest pain, this study only includes patients without any known explanation for their chest pain. AIM: To analyze gender differences regarding pain characteristics, psychosocial factors and health-related quality of life among patients diagnosed unexplained chest pain. METHODS AND RESULTS: The results are based on 179 patients (101 men, 78 women) between 16 and 69 years old (mean age 45.3) consecutively admitted to Emergency Department. Pain characteristics were assessed by Pain-O-Meter. Social relationships, depression, anxiety, and health-related quality of life were measured by a self-administered questionnaire. There were no gender differences regarding chest pain intensity; however women described their pain as burning (p<0.01) and frightening (p<0.03) more often than men. Men reported less depression (p<0.01) and less trait anxiety (p=0.01) than women. Chest pain intensity did not significantly impact health-related quality of life except physical functioning in men (p=0.05). CONCLUSION: Gender differences were few. Chest pain intensity did not significantly impact health-related quality of life.

The purpose of this study was to investigate the use of and attitudes among young people toward pornography and their sources of information about sexuality. Eight hundred and seventy-six young people ages 15-25 years (555 females and 321 males) who visited a youth center in Sweden for a period of 1 year answered a questionnaire about their use of pornography, their attitudes toward pornography, and sources of information about sexuality. Although most had seen pornographic movies, the youngest boys reported viewing the most pornography. The male participants reported that the most common reason they viewed pornography was to get aroused and to masturbate, whereas the female participants stated that they viewed pornography out of curiosity. The most frequent source of information about sexuality was peers. These results illustrate the importance of sex education to give factual information about sexuality and to counteract the messages about sexuality presented in pornography.

BACKGROUND: We have previously shown that insulin is not a major risk factor for CHD. Our data have been re-analysed with longer follow-up and the homeostasis model assessment (HOMA) method. DESIGN: Prospective cohort study of 57- and 67-year-old men. METHODS: Insulin resistance was estimated with the HOMA equation. Standard methods were used to measure risk factors. The endpoint (CHD) was the combination of non-fatal myocardial infarction and fatal CHD during 13 years of follow-up. RESULTS: The risk of CHD increased 2.5-fold in known diabetics compared with those with normal glucose tolerance, 2.2-fold among those in the highest compared with the lowest quintile of insulin resistance, and 2.4-fold among those in the highest compared with the lowest quintile of fasting insulin. Increased physical activity decreased the risk of CHD by 65%. Cholesterol was also a significant risk factor for CHD but blood pressure, obesity and smoking were not related to the incidence of CHD. CONCLUSION: Insulin resistance is a significant risk factor for CHD. Whether it is a causal risk factor remains to be proven. Regular physical activity protects against CHD.
