Background: A growing body of literature demonstrates internet-based smoking cessation interventions as a promising aid in helping people quit smoking. However, the underlying mechanisms of how these interventions influence the cessation process are still relatively unknown. Several studies have indicated blogging as a potential source in providing social support to users of internet-based smoking cessation interventions and thereby enhance their change of succeeding in quitting. Objective: The study aimed to investigate themes discussed on a blog in an internet-based smoking cessation intervention. In addition, we examined if blogging could provide social support for people in a smoking cessation process. Method: The study was based on messages posted from 1 January 2012 to 29 February 2012 on the blog of the internet-based smoking cessation programme DDSP, operated by the Danish Cancer Society. Messages were coded according to themes using Grounded Theory, and additionally data about bloggers were analyzed. Result: In total, 1663 messages were posted within the 2-month period, and we identified 16 themes. The majority of messages contained personal stories or experiences (53%), provided emotional support (34%) or congratulated other users (17%). The messages were found capable of supplying social support to members on the blog. In addition, we found that only a minority of users who viewed the blog participated actively in posting messages, and only a minority was highly active bloggers. Conclusions: The blog offers a unique platform for informal conversations about quitting smoking and is important in providing social support to people in a smoking cessation process.

Aims: Tobacco-smoking behaviours of young people between the age of 18 and 25 years are less understood than those of middle-aged people. The aim of this study is to contribute to improved knowledge of some of the factors that are associated with smoking and cessation among young people. Methods: We use the most recently available public health survey data from the southern region of Skåne in Sweden to analyze these factors. The survey is a cross-sectional study with a total sample size of 28,198 individuals with 2801 in the age category of interest. We apply statistical measures of association between smoking and gender and also model the relationship between smoking and smoking cessation and the role of a set of sociodemographic determinants by means of logistic regression to estimate odds ratios. Results: The findings include significant differences between the younger age group and the older group with respect to the odds of smoking and method of cessation. We also find differences between young women and men with regard to smoking prevalence, intensity and cessation methods. In particular, young women attempt to quit smoking by means of unassisted methods to a significantly higher extent than do young men. Conclusions: There are significant differences between young people and older individuals with respect to a range of smoking behaviours. There are also strong gender effects within the group of young people. Policy development and anti-smoking interventions need to take such differences into consideration for improved effectiveness.

Background: Sweden has shown a decreasing tendency in the incidence of myocardial infarction (MI), except among middle-aged women. The incidence among middle-aged immigrant women is less explored. Aim: To determine if foreign-born women have a higher risk of MI as compared to women born in Sweden. Furthermore, to examine if physical activity (PA) modifies the risk of MI regardless of immigration status and smoking habits. Methods: The Malmö Diet and Cancer Study was used for analyses. A total of 16,776 women aged 45–73 years participated. The mean follow-up time was 13.8±4 years. Results: Mean age was 57.4±7.9 years. No difference was found in incidence of MI between Swedish and immigrant women (p=0.72). For current smokers among Swedish women, the relative risk (RR) with no/low PA was 2.93 (95% CI 2.07–4.14) and with moderate/high PA, the RR was 2.21 (95% CI 1.61–3.03) with no/low PA-never smoker as the reference group. Among immigrant smoking women, the RR with no/low PA was 4.56 (95% CI 1.62–12.8) and with moderate/high PA, the RR was 3.27 (95% CI 1.21–8.84) with no/low PA-never smoker as the reference group. Conclusions: PA reduces the risk of MI in non-smokers as well as in smokers, regardless of immigration status. Furthermore, PA was even more beneficial for women born outside Sweden. Against this background, immigrant women ought to get special consideration and attention from both caregivers and public health workers.

Aims: The primary aim is to estimate the prevalence of Swedish adolescents who perceive their parent(s) to have alcohol problems. Additional research questions pertain to the prevalence of adolescents who think someone close to them drinks too much alcohol and if this has hurt them or caused them problems. Methods: A cross-sectional design was employed using a web-based survey targeted to 1000 Swedish 16–19-year-olds randomly selected from a web panel. The questionnaire included the CAST-6 scale, used to assess whether or not participants perceived their parents’ alcohol consumption as problematic, and questions relating to whether or not they think someone close to them drinks too much and if this has caused them problems. Data was weighted using a post-stratification procedure. Results: The proportion of adolescents classified as having parents with alcohol problems was 20.1%. Further, 44.0% reported that they think someone close to them drinks too much alcohol and 9.6% that this has hurt them or caused them problems. Conclusions: These results indicate that the problem is widespread. Our findings are similar to previous research where a more indirect methodology has been adopted, using either psychiatric interviews or self-reported alcohol consumption of adults, to estimate the magnitude of the problem.

Aims: Sickness absence is of considerable concern in both Norway and Denmark. Labour Force Surveys indicate that absence in Norway is about twice that in Denmark and twice that of the mean reported by the Organisation for Economic Co-operation and Development. This study compares absence patterns according to age, percentage of employment, and occupation between municipal employees in the health and care sectors in two municipalities in Norway and Denmark. Methods: Data recorded in the personnel registers of the municipalities of Kristiansand, Norway and Aarhus, Denmark were extracted for the years 2004 and 2008, revealing 3498 and 7751 employee-years, respectively. We calculated absence rates together with number of sick leave episodes, and their association with the above-mentioned covariates. Gender-specific comparative descriptive statistics and negative binomial regression analysis were performed. Results: The sickness absence rate in women was 11.3% in Norway (95% confidence interval [CI] 11.2–11.4) and 7.0% in Denmark (95% CI 7.0–7.1) whereas mean number of sick leave episodes among women was 2.4 in Denmark, compared to 2.3 in Norway (p = 0.02). Young employees in Denmark had more sick leave episodes than in Norway. Proportion of absentees was higher in Denmark compared to Norway (p < 0.0001). Conclusions: The finding of that more employees in Denmark have more frequent, but shorter sick leave episodes compared to Norway, for whatever reasons, may indicate that more frequent sick leaves episodes prevent higher sick leaves rates.

Aims: The need to combine active employment and parenthood is a reality for many parents today. Knowing more about which work place factors are associated with better or worse health could help employers to form a work environment that provides optimal conditions to maintain or increase health and work engagement in this group. The aim of this study was to explore possible associations between different subjective and objective work factors and benefits, and a range of outcome variables such as stress, symptom report, wellbeing, work-related fatigue, work engagement, and work–family conflict among working mothers and fathers with small children. Methods: Cross-sectional analyses of associations between work place factors categorised into three different dimensions; flexibility, benefits, and attitude and the outcome measures were performed, including questionnaire responses from 1562 working parents. Results: The results showed that work place factors related to flexibility and, especially among women, attitude to parenthood appear to have the strongest effect on working parents’ subjective stress and wellbeing, while benefits appear to have less impact. Except regarding factors related to attitudes at the work place, most associations were similar among men and women. Conclusions: Most likely, different factors are better suited or more important for some individuals than others depending on their total work, as well as family situation and also depending on individual factors such as personality and priorities. A positive attitude towards parenthood and a flexible work situation seem, however, beneficial for the general wellbeing and work engagement among working parents.

Background: Prevalence of sedentary behaviour is high in many countries, but little is known about temporal trends in sitting time. Objective: To examine temporal changes in sleep and domain-specific sedentary behaviour and moderate to vigorous leisure time physical activity (MVPA). Methods: Two cross-sectional population-based surveys of 25–79-year-old inhabitants were conducted in The Capital Region of Denmark in 2007 (N = 69.800, response rate 52.3%) and 2010 (N = 77.517, response rate 54.8%). Information on sedentary behaviour and physical activity was obtained from self-report questionnaire and sociodemographic information from central registers. Data were weighted for survey design and for non-response and were analysed by multiple regression analyses. Results: In 2007, the entire survey population reported a mean daily sleeping duration of 7.4 hours, leisure time sitting of 3.4 hours per day, occupational sitting of 4.4 hours per day, MVPA of 0.87 hours per day and a total 24-hour energy expenditure of 40.12 METs per day. In 2010, duration of sleep was unaltered (p = 0.1), sedentary leisure time and sedentary work time had increased by 12.6 minutes (p < 0.0001) and 13.2 minutes (p < 0.0001) per day, respectively. Time spent on MVPA had increased by 2.9 minutes per day (p < 0.0001). The 24-hour energy expenditure had decreased by 0.41 METs (p < 0.0001). Conclusions: Adult Danish men and women spend an increased amount of time sitting down at work and during leisure time, but also on leisure time MVPA. As duration of sleep is unaltered findings suggest that low intensity physical activity may be displaced in everyday life.

Aims: Insomnia is a large health problem. In some prior studies, positive associations between insomnia symptoms and sickness absence have been observed. There is, however, no previous nationwide cohort study of clinically diagnosed insomnia and risk of incident sickness absence. Methods: Prospective nationwide cohort study based on Swedish population-based registers including all 4,956,358 individuals registered as living in Sweden on 31 December 2004/2005, aged 17–64 years, not on disability pension, old-age pension or on-going sickness absence. Those having insomnia inpatient or outpatient care, defined as having at least one admission/specialist visit with a main or secondary diagnosis of disorders of initiating and maintaining sleep [insomnias] (ICD-10: G47.0) during 2000/2001–2005, were compared to those with no such care. All-cause and diagnosis-specific incident sickness absence were followed during 2006–2010. Incidence rate ratios (IRRs) and 95% confidence intervals (CIs) were estimated by Cox proportional hazards regression. Results: In models adjusted for prior sickness absence, socio-demographic factors and inpatient and specialized outpatient care, associations between insomnia and increased risks of all-cause sickness absence (IRR 1.18, 95% CI 1.04–1.35) and sickness absence due to mental diagnoses (IRR 1.75, 95% CI 1.36–2.25) were observed. After further adjustment for insomnia medications these associations disappeared. No associations between insomnia and risk of sickness absence due to cancer, circulatory or musculoskeletal diagnoses, or injuries, were observed. Conclusions: In this nationwide cohort study, we observed increased risks of all-cause sickness absence and sickness absence due to mental diagnoses after adjustment for several potential confounders that disappeared after further adjustment for insomnia medications.

Purpose: To describe sexual health risks in an understudied group, youth in detention, and compare these to sexual health risks among non-detained youth. In addition, variables predicting adverse sexual health outcomes are sought and compared. Methods: In 2009, a self-administered questionnaire on sexuality was conducted amongst youth in Sweden. In 2010, the same Internet-based questionnaire was applied in a study at Swedish detention centres. In this article, sexually active youth aged 15–20 years in the two groups are compared and bivariate logistic regression analyses are conducted in order to find predictors of adverse sexual health outcomes, among detainees and non-detainees respectively. Results: Major differences between the detained and the non-detained concerning a majority of risk-taking variables exist. Conclusions: Although detained youth display several risky sexual behaviors, no specific risk factors are found in a logistic regression analysis. However, this is a vulnerable group. The mere fact that an adolescent is placed at a detention centre should be an imperative for professionals to address the subject of sexual health and safer sex. Furthermore, the results will be used in a forthcoming sex education curriculum tailored especially at detained youth. This is one, but by far not the only way to minimize the health inequalities that are presented in this study.

Aim: To study the sociodemographic characteristics and attitudes associated with buying sex among Finnish men residing in different areas of Finland. Methods: A population-based questionnaire survey among 18–74-year-old Finns in 1999 with a response rate among men of 38%. The data on 575 men were analysed with descriptive statistics and logistic regression. Results: The overall proportion of men ever having bought sex was 14%. Men who at the time of the survey were in the age group 30–39, aged 50 or over, with 13–15 years of educational study, entrepreneurs, and with high income, were more likely to have ever bought sex. Being married and living with a partner at the time of the study lowered the odds of ever having bought sex. The differences between the groups were mostly the same in all residential areas, though the strength and statistical significance varied. The exception was the association with education, which occurred only in small towns. The effect of attitudes to buying sex was strong and did not differ by area of residence. Conclusions: Many men with different sociodemographic characteristics reported having bought sex. There was no noticeable variation in the sociodemographic characteristics and attitudes of men having bought sex by the area of residence. More current research is needed on the motives and health consciousness of men buying sex.

Aims: Understanding the determinants of social and coping inequalities in subclinical cardiovascular disease is an important prerequisite in developing and implementing preventive strategies. The aim of this study was to investigate the association between social factors and coping status, respectively, and subclinical coronary artery disease (CAD) in middle-aged Danes. Methods: This is a DanRisk screening substudy, thus including healthy Danish males and females aged 50 or 60 years. Social measures included grade of education, employment and co-habiting status. The coping status was estimated by the general self-efficacy (GES) scale. Coronary artery calcification (CAC) was assessed by computed tomography using the Agatston score (AS). Conventional clinical risk factors included sex, family history of CAD, BMI > 25, smoking, hypercholesterolaemia and hypertension. Results: In 568 individuals the prevalence of subjects with CAC was 267 (45%). Independent predictors of CAC in males were age (OR = 1.10, 95% CI = 1.04–1.16, p < 0.001), smoking (OR = 1.75, 95% CI = 1.03–2.99, p = 0.038), and low co-habiting status (OR = 3.66, 95% CI = 1.19–11.25, p = 0.023). Independent predictors in females were age (OR = 1.67, 95% CI = 1.02–1.12, p = 0.006), and smoking (OR = 1.71, 95% CI = 1.06–2.78, p = 0.029). Higher AS was associated to lower employment level in females (p = 0.001) but not in males (p = 0.833). Conclusions: Social factors are associated to the prevalence and severity of CAC in asymptomatic middle-aged individuals with gender differences. The relative value of gender specific social versus conventional clinical risk factors in the risk assessment of subclinical CAC in middle-aged individuals needs further investigation in future prospective studies.

Aim: Poor health-related quality of life (HRQoL) is associated with increased use of healthcare services, but it remains unclear which individuals have a heightened risk in the general population. Methods: A Swedish population-based cross-sectional survey was conducted in 2008. Predefined risk characteristics including sex, age, educational level, marital status, body mass index, diseases, physical activity, and tobacco smoking were collected by a self-report questionnaire. Five aspects of the EORTC QLQ-C30 were used to assess HRQoL: physical, role, emotional, social, and cognitive function. Participants were defined as having “poor HRQoL” if they scored ≥10 points (scale 0–100) lower than the mean score of the total sample. To assess the characteristics of individuals with poor HRQoL, classification and regression tree (CART) analysis was performed. Results: A total of 4910 (70.5% participation rate) randomly selected individuals participated in the study. The CART analysis showed that for each of the five functional aspects of HRQoL, the most important covariate HRQoL was the number of reported diseases, while the second strongest covariate was physical inactivity. Conclusion: This large population-based study indicates that a higher number of diseases and physical inactivity are the most important covariates of poor HRQoL in the Swedish general population.

Aim: The academic performance of children impacts future educational attainment which may increase socioeconomic status which again influences their health. One of several factors that might affect academic performance is the diet. The aim of this study was to investigate the cross sectional relation between diet and self-reported reading-, writing-, and mathematical difficulties in Norwegian adolescents. Methods: In total, 475 ninth- and tenth-grade students out of 625 eligible ones from four different secondary schools in three different municipalities in Vest-Agder County, Norway, participated, giving a participation rate of 77%. The students filled in a questionnaire with food frequency questions of selected healthy and unhealthy food items, questions of meal frequency and different learning difficulties. Results: Regular breakfast was significantly associated with decreased odds of both writing and reading difficulties (OR: 0.44 (0.2–0.8), p = 0.01) and mathematical difficulties (OR: 0.33 (0.2–0.6), p ≤ 0.001). In addition, having lunch, dinner and supper regularly were associated with decreased odds of mathematical difficulties. Further, a high intake of foods representing a poor diet (sugar-sweetened soft drinks, sweets, chocolate, savory snacks, pizza and hot dogs) was significantly associated with increased odds of mathematical difficulties. Conclusions: Having a less-frequent intake of unhealthy foods and not skipping meals are associated with decreased odds of self-reported learning difficulties in Norwegian adolescents in this study. The results of this study support the need for a larger study with a more representative sample.

Background: The economic effects of waterborne outbreaks have rarely been reported. A large waterborne outbreak occurred in the town of Nokia in Finland in 2007 with half of the population in the contaminated area suffering from gastroenteritis. We studied the healthcare costs of this outbreak. Methods: Healthcare costs were studied using register data from the Nokia Health Care Centre, data collected in the regional university hospital, and data from laboratory register on stool samples. Results: Total excess healthcare costs were EUR 354,496, which is approximately EUR 10 per resident of Nokia. There were 2052 excess visits because of gastroenteritis in Nokia Health Care Centre, 403 excess episodes in the university hospital, and altogether over 2000 excess stool samples due to the outbreak. Care in the Nokia Health Care Centre accounted for 44% and care in the university hospital for 42% of the excess healthcare costs while stool samples accounted for only 10%. Conclusions: Despite the high morbidity, the total cost was low because most patients had a relatively mild illness. The situation would have been worse if the microbes involved had been more hazardous or if the financial situation of the community had been worse. Prevention of waterborne outbreaks is important, as there is a risk of severe short- and long-term health effects and substantial health-economic costs.
