- AIM: Preterm birth is associated with a number of physical and mental health issues. The aim of this study was to find out if there was also any association between individuals born preterm in Sweden between 1984 and 2006 and the risk of unintentional injuries during childhood, adolescence and young adulthood METHODS: The study followed 2,297,134 individuals, including 5.9% born preterm, from 1985 to 2007 for unintentional injuries leading to hospitalisation or death (n=244,021). The males and females were divided into four age groups: 1-5 years, 6-12 years, 13-18 years and 19-23 years. Hazard ratios were calculated for falls, transport injuries and other injuries RESULTS: After adjusting for a comprehensive set of covariates, some of the preterm subgroups demonstrated slightly increased risks of unintentional injuries, while others showed slightly decreased risks. However, most of the estimates were borderline or non-significant in both males and females. In addition, the absolute risk differences between individuals born preterm and full term were small CONCLUSION: Despite the association between preterm birth and a variety of physical and mental health consequences, this study shows that there is no consistent risk pattern between preterm birth and unintentional injuries in childhood, adolescence and young adulthood. ©2012 The Author(s)/Acta Paediatrica ©2012 Foundation Acta Paediatrica©2012 The Author(s)/Acta Paediatrica ©2012 Foundation Acta Paediatrica.

- BACKGROUND: Little is known about whether the four main manifestations of arterial vascular disease (coronary heart disease=CHD, ischemic stroke, peripheral artery disease=PAD, and aortic (i.e. atherosclerosis/aneurysm) disease=AD) share familial susceptibility. The aim of this nationwide study was to determine the familial risks of concordant (same disease in proband and exposed relative) and discordant (different disease in proband and exposed relative) cardiovascular disease (CVD). METHODS: Data from the Swedish Multigeneration Register on individuals aged 0-76years were linked to Swedish Hospital Discharge Register data for the period 1964-2008. Standardized incidence ratios (SIRs) for CHD (n=140,708 cases), ischemic stroke (n=73,771), PAD (n=18,982) and AD (n=7879) were calculated for siblings of individuals hospitalized due to CHD, stroke, PAD or AD compared to those of unaffected siblings. The procedure was repeated for parent-offspring and spouses. RESULTS: All concordant and discordant sibling risks were increased for both males and females. Concordant risks were generally higher than discordant risks. The highest sibling risks were observed for premature concordant disease (<55years for males and <65years for females): SIR for CHD=1.93 (95% CI: 1.90-1.96), SIR for ischemic stroke=1.45 (1.39-1.50), SIR for PAD=2.76 (2.54-3.00), and SIR for AD=6.36 (5.28-7.59). Premature parent-offspring transmission followed the same pattern. The disease risk was modestly increased in spouses, highest for AD (SIR=1.48 (1.28-1.69)) and PAD (SIR=1.27 (1.21-1.32)). CONCLUSIONS: The four main manifestations of CVD share familial susceptibility, but unique site-specific familial factors may exist.

- Socioeconomic inequalities and infant mortality of 46 470 preterm infants born in Sweden between 1992 and 2006. Paediatric and Perinatal Epidemiology 2011; 25: 357-365. Studies on possible sociodemographic inequities in the survival of preterm infants are scarce. Individual and neighbourhood sociodemographic factors are related to preterm birth and to infant mortality in full-term infants. The aim here was to examine whether infant mortality in Swedish preterm infants is related to individual and neighbourhood sociodemographic factors, and to study whether the hypothesised association between neighbourhood deprivation and infant mortality persists after accounting for individual sociodemographic factors. The study included 46 470 infants with a gestational length of < 37 weeks, born in Sweden between 1992 and 2006. Neighbourhood deprivation was assessed by an index (education, income, unemployment, welfare assistance) in small geographical units, and categorised into low, moderate and high deprivation. Adjusted odds ratios for infant mortality were examined in relation to individual and neighbourhood sociodemographic factors. After adjusting for maternal age, infant mortality was associated with the following sociodemographic variables: maternal non-married/non-cohabiting status, low family income, low maternal education and rural status. After full adjustment, the odds ratio [95% confidence interval] was 2.98 [2.42, 3.67] for low family income compared with high family income. An increase in infant mortality was also associated with high neighbourhood deprivation; however, this increased risk no longer remained statistically significant after adjusting for individual sociodemographic factors. In conclusion, this study showed an increased infant mortality in preterm infants born to women with a less favourable sociodemographic profile.

Tidskriftsartikel (refereegranskat)abstract
- Background: The aim of this longitudinal study was to analyze whether mean Body Mass Index (BMI), assessed at four occasions, changed within different age groups and birth cohorts over time, i.e., between 1980/81 and 2004/05, after adjustment for possible confounders. Methods: A sample of 2728 men and 2770 women aged 16-71 years at study start were randomly drawn from the Swedish Total Population Register and followed from 1980/81 to 2004/05. The same sample was assessed on four occasions during the 24-year study period (i.e., every eighth year). The outcome variable, BMI, was based on self-reported height and weight. A mixed model, with random intercept and random slope, was used to estimate annual changes in BMI within the different age groups and birth cohorts. Results: Mean BMI increased from 24.1 to 25.5 for men and from 23.1 to 24.3 for women during the 24-year study period. The annual change by age group was highest in the ages of 32-39, 40-47 and 48-55 years among men, and in the ages of 24-31, 32-39, and 40-47 years among women. The highest annual changes were found in the youngest birth cohorts for both men and women, i.e., those born 1958-65, 1966-73, and 1974-81. For each birth cohort, the annual change in BMI increased compared to the previous, i.e., older, birth cohort. In addition, age-by-cohort interaction tests revealed that the increase in BMI by increasing age was higher in the younger birth cohorts (1966-1989) than in the older ones. Conclusions: Public health policies should target those age groups and birth cohorts with the highest increases in BMI. For example, younger birth cohorts had higher annual increases in BMI than older birth cohorts, which means that younger cohorts increased their BMI more than older ones during the study period.

- OBJECTIVES: To analyze whether there is an association between neighborhood deprivation and cervical cancer morbidity and mortality, beyond individual level characteristics. DESIGN: The entire Swedish population aged 25 to 74, a total of 1.9million women, were followed from January 1, 1990, until hospital admission due to cervical cancer during the study period, or the end of the study on December 31, 2008. Multilevel logistic regression was used in the analysis with individual level characteristics (age, marital status, family income, education, immigration status, urban/rural status, mobility, comorbidities, parities, and number of partners) at the first level and level of neighborhood deprivation at the second level. Neighborhood deprivation was measured at small area market statistics level by the use of an index. RESULTS: There was a strong association between level of neighborhood deprivation and cervical cancer morbidity and mortality. In the full model, which took account of the individual level characteristics, the risks of cervical cancer morbidity and mortality were 1.25 and 1.36, respectively, in the most deprived neighborhoods. The between neighborhood variance was over twice the standard error, indicating significant differences in cervical cancer morbidity and mortality between neighborhoods. CONCLUSIONS: This study is the largest to date of the influences of neighborhood deprivation on cervical cancer morbidity and mortality. The results suggest that neighborhood characteristics affect cervical cancer morbidity and mortality independently of individual level sociodemographic characteristics. Both individual and neighborhood level approaches are important in health care policies.

Study protocol: a multi-professional team intervention of physical activity referrals in primary care patients with cardiovascular risk factors-the Dalby lifestyle intervention cohort (DALICO) study
- 2012
-
Ingår i: BMC Health Services Research. - : Springer Science and Business Media LLC. - 1472-6963. ; 12
-
Tidskriftsartikel (refereegranskat)abstract
- Background: The present study protocol describes the trial design of a primary care intervention cohort study, which examines whether an extended, multi-professional physical activity referral (PAR) intervention is more effective in enhancing and maintaining self-reported physical activity than physical activity prescription in usual care. The study targets patients with newly diagnosed hypertension and/or type 2 diabetes. Secondary outcomes include: need of pharmacological therapy; blood pressure/plasma glucose; physical fitness and anthropometric variables; mental health; health related quality of life; and cost-effectiveness. Methods/Design: The study is designed as a long term intervention. Three primary care centres are involved in the study, each constituting one of three treatment groups: 1) Intervention group (IG): multi-professional team intervention with PAR, 2) Control group A (CA): physical activity prescription in usual care and 3) Control group B: treatment as usual (retrospective data collection). The intervention is based on self-determination theory and follows the principles of motivational interviewing. The primary outcome, physical activity, is measured with the International Physical Activity Questionnaire (IPAQ) and expressed as metabolic equivalent of task (MET)-minutes per week. Physical fitness is estimated with the 6-minute walk test in IG only. Variables such as health behaviours; health-related quality of life; motivation to change; mental health; demographics and socioeconomic characteristics are assessed with an electronic study questionnaire that submits all data to a patient database, which automatically provides feed-back to the health-care providers on the patients' health status. Cost-effectiveness of the intervention is evaluated continuously and the intermediate outcomes of the intervention are extrapolated by economic modelling. Discussions: By helping patients to overcome practical, social and cultural obstacles and increase their internal motivation for physical activity we aim to improve their physical health in a long- term perspective. The targeted patients belong to a patient category that is supposed to benefit from increased physical activity in terms of improved physiological values, mental status and quality of life, decreased risk of complications and maybe a decreased need of medication.
