The association between perceived relationship discord at childbirth and parental postpartum depressive symptoms: a comparison of mothers and fathers in Sweden
2012
Ingår i: Uppsala Journal of Medical Sciences. - : Uppsala Medical Society. - 0300-9734 .- 2000-1967 .- 0300-9726. ; 117:4, s. 430-438

Aim. To examine whether mothers' and fathers' levels of perceived relationship discord at childbirth were associated with postpartum depressive symptoms when the child was 3 months old. Another aim was to examine parents' levels of self-reported depressive symptoms. The hypothesis was that parents with high levels of perceived relationship discord have higher levels of postpartum depressive symptoms than parents with low levels of perceived relationship discord. Method. One week after childbirth, 305 couples' perceived level of relationship discord was measured using the Dyadic Consensus Subscale (DCS) of the Dyadic Adjustment Scale (DAS). At 3 months postpartum, the same couples answered the Edinburgh Postnatal Depression Scale (EPDS) questionnaire. The relations between perceived level of relationship discord and postpartum depressive symptoms were analysed using standard non-parametric statistical methods. Results. The mothers and fathers partly differed regarding which areas of their relationship they perceived that they disagreed with their partners about. Furthermore, 16.5% of the mothers and 8.7% of the fathers reported postpartum depressive symptoms, and there was a moderate level of correlation between the DCS and EPDS scores. Conclusion. These results may be useful for professionals in antenatal care and child health centres as well as for family caregivers who need to be aware that mothers and fathers may have different views on relationship discord and of the high level of depressive symptoms in recent parents. Further research is needed to examine perceived relationship discord and the development of depressive symptoms postpartum over a longer term.

Incidence of ICD-based diagnoses of alcohol-related disorders and diseases from swedish nationwide registers and suggestions for coding
2020
Ingår i: Clinical Epidemiology. - Macclesfield, United Kingdom : Dove Medical Press Ltd.. - 1179-1349. ; 12, s. 1433-1442
Tidskriftsartikel (refereegranskat) abstract
Aim: To improve consistency between register studies in Sweden and ensure valid comparisons of possible changes in alcohol-related disorders and diseases (ARDDs) over time, we propose a definition of ARDDs. Based on this definition, we examined Sweden’s incidence rates of ARDDs from 1970 to 2018 in non-primary healthcare settings (inpatient and outpatient). Methods: Swedish Society of Epidemiology members were invited to give feedback on the International Classification of Disease (ICD) codes with a potential link to alcohol use. We then calculated age-standardised and age-specific incidence of ARDDs over time according to the National Patient Register, and the lifetime prevalence of ARDDs diagnosed in adults alive in Sweden on Dec 31, 2018. Results: Sweden’s estimated incidence of ARDDs increased substantially after introducing the new ICD-9 codes in 1987. In the past 10 years (2009–2018), the incidence of ARDDs has been stable (males: 110/100,000 person-years, females: 49/100,000 person-years). Requiring at least two ICD records for diagnosed ARDDs led to a somewhat lower incidence of ARDDs (males: 71 per 100,000 person-years, females: 29 per 100,000 person-years). In Sweden, the lifetime prevalence of diagnosed ARDDs in adults on Dec 31, 2018, was 1.9% (95% CI=1.9–1.9). Conclusion: In this nationwide study, we found an incidence of ARDDs of 50–100/ 100,000 person-years. In 2018, 1 in 52 adults in Sweden had been diagnosed with ARDDs in the National Patient Register.

Socioeconomic status and alcohol use disorders across the lifespan : A co-relative control study
2019
Ingår i: PLoS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 14:10, s. 0224127-0224127
Tidskriftsartikel (refereegranskat) abstract
OBJECTIVES: Alcohol use disorders (AUD) is well known to aggregate in families and is associated with socioeconomic status (SES). The objective was to study the effect of education, income and neighborhood SES in adulthood on AUD, and to explore whether the potential associations were confounded by shared familial factors, by using a co-relative control design. METHODS: Data on AUD was drawn from the Swedish inpatient and outpatient care registers; prescription drug register; and crime data. Through national population registers we collected information on income, education and neighborhood SES at age 25, 30, 35 and 40 years in all individuals born in Sweden between 1950 and 1980. Each sex-specific stratum consisted of approximately 750,000-1,200,000 individuals, who were followed for AUD for a mean follow-up time ranging between 10 and 15 years until the end of 2013. Cox proportional hazards models were used to investigate the risk of AUD as a function of income, education and neighborhood SES in the general population and in pairs of first cousins and full siblings within the same sex, who differed in their exposure to the SES measure. RESULTS: Higher educational level, higher income and higher neighborhood SES were all associated with a reduced risk for AUD for both males and females in all ages. The potentially protective effect remained but was attenuated when comparing pairs of first cousins and full siblings. CONCLUSIONS: High educational level and income in adulthood, as well as high neighborhood socioeconomic status, may represent protective factors against alcohol use disorders, even when shared familial factors, e.g. childhood socioeconomic status and genetic factors, have been taken into account.

Triangulation of evidence on immigration and rates of alcohol use disorder in Sweden : Evidence of acculturation effects
2023
Ingår i: Alcoholism: Clinical and Experimental Research. - : Wiley. - 0145-6008 .- 1530-0277. ; 47:1, s. 104-115
Tidskriftsartikel (refereegranskat) abstract
Background: This study aimed to determine the robustness of the impact of immigration on risk for alcohol use disorder (AUD) using different measures, designs, and immigrant regional cohorts. Methods: The analytic sample included all individuals born between 1950 and 1990 and registered in Sweden from 1973 to 2017. Using Cox regression models, we examined the risk for AUD from Swedish nationwide registries in immigrants to Sweden from seven geographical regions: Africa, Asia and Oceania, Eastern Europe, Finland, Latin America and the Caribbean, Middle East/North Africa, and Western countries. We assessed greater exposure to Swedish culture, which we interpreted as increasing acculturation, by (i) comparing first-generation immigrants and their children with no and one native Swedish parent and (ii) examining age at immigration. The baseline comparison group was the native Swedish population. We also examined AUD risk in first-generation sibling pairs discordant for their age at immigration. Results: In nearly all immigrant cohorts in Sweden, increasing degrees of acculturation, as assessed by both our variables, were associated with rates of AUD that approached those of the Swedish population. These findings occurred in both men and women and both regional cohorts whose first-generation immigrants had lower and higher levels of AUD than native-born Swedes. For most cohorts, the rates of change with acculturation were greater in women than in men. In sibling pairs from most regions, the sibling who was younger at immigration had a higher rate of AUD. Conclusions: An examination of both sexes and two different proxies for acculturation provides consistent support for socio-cultural influences on AUD risk. Our co-sibling analyses suggest that a meaningful proportion of this effect is likely to be causal in nature.

Exercise is medicine : Primary care counseling on aerobic fitness and muscle strengthening
2019
Ingår i: Journal of the American Board of Family Medicine. - : American Board of Family Medicine (ABFM). - 1557-2625 .- 1558-7118. ; 32:1, s. 103-107
Tidskriftsartikel (refereegranskat) abstract
Patient counseling on physical fitness remains underutilized in primary care, despite its clinical and cost effectiveness. Most counseling interventions have focused on aerobic activity and neglected another vital component of physical fitness, muscle strengthening, which has recently been shown to be independently protective against cardiometabolic diseases and premature mortality. This article reviews the latest scientific evidence and makes recommendations toward a more comprehensive approach for promoting physical fitness in primary care. Given the high prevalence and wide-ranging health impacts of physical inactivity, counseling on physical fitness should be a standard part of wellness promotion and disease prevention and treatment for all patients. Interventions that include muscle strengthening will have a significantly greater impact on health outcomes than those focused on aerobic fitness alone. Counseling to promote both aerobic fitness and muscle strengthening is indicated for all patients, irrespective of body weight, and should begin early in life and continue across the life course.

Interactive Effects of Aerobic Fitness, Strength, and Obesity on Mortality in Men
2017
Ingår i: American Journal of Preventive Medicine. - : Elsevier BV. - 0749-3797. ; 52:3, s. 353-361
Tidskriftsartikel (refereegranskat) abstract
Introduction: Low aerobic fitness, low muscular strength, and obesity have been associated with premature mortality, but their interactive effects are unknown. This study examined interactions among these common, modifiable factors, to help inform more-effective preventive interventions. Methods: This national cohort study included all 1,547,478 military conscripts in Sweden during 1969-1997 (97%-98% of all men aged 18 years each year). Aerobic fitness, muscular strength, and BMI measurements were examined in relation to all-cause and cardiovascular mortality through 2012 (maximum age, 62 years). Data were collected/analyzed in 2015-2016. Results: Low aerobic fitness, low muscular strength, and obesity at age 18 years were independently associated with higher all-cause and cardiovascular mortality in adulthood. The combination of low aerobic fitness and muscular strength (lowest versus highest tertiles) was associated with twofold all-cause mortality (adjusted hazard ratio=2.01; 95% CI=1.93, 2.08;. p<0.001; mortality rates per 100,000 person years, 247.2 vs 73.8), and 2.6-fold cardiovascular mortality (2.63; 95% CI=2.38, 2.91;. p<0.001; 43.9 vs 8.3). These factors also had positive additive and multiplicative interactions in relation to all-cause mortality (their combined effect exceeded the sum or product of their separate effects;. p<0.001), and were associated with higher mortality even among men with normal BMI. Conclusions: Low aerobic fitness, low muscular strength, and obesity at age 18 years were associated with increased mortality in adulthood, with interactive effects between aerobic fitness and muscular strength. Preventive interventions should begin early in life and include both aerobic fitness and muscular strength, even among those with normal BMI.

Alcohol Use Disorder and Risk of Suicide in a Swedish Population-Based Cohort
2020
Ingår i: The American journal of psychiatry. - : American Psychiatric Association Publishing. - 1535-7228 .- 0002-953X. ; 177:7, s. 627-634
Tidskriftsartikel (refereegranskat) abstract
OBJECTIVE: The authors examined the association between alcohol use disorder (AUD) and risk of suicide, before and after accounting for psychiatric comorbidity, and assessed the extent to which the observed association is due to a potentially causal mechanism or genetic and familial environmental confounding factors that increase risk for both. METHODS: Longitudinal population-wide Swedish medical, criminal, and pharmacy registries were used to evaluate the risk of death by suicide as a function of AUD history. Analyses employed prospective cohort and co-relative designs, including data on 2,229,880 native Swedes born between 1950 and 1970 and observed from age 15 until 2012. RESULTS: The lifetime rate of suicide during the observation period was 3.54% for women and 3.94% for men with AUD, compared with 0.29% and 0.76% of women and men, respectively, without AUD. In adjusted analyses, AUD remained robustly associated with suicide: hazard ratios across observation periods ranged from 2.61 to 128.0 among women and from 2.44 to 28.0 among men. Co-relative analyses indicated that familial confounding accounted for some, but not all, of the observed association. A substantial and potentially causal relationship remained after accounting for a history of other psychiatric diagnoses. CONCLUSIONS: AUD is a potent risk factor for suicide, with a substantial association persisting after accounting for confounding factors. These findings underscore the impact of AUD on suicide risk, even in the context of other mental illness, and implicate the time frame shortly after a medical or criminal AUD registration as critical for efforts to reduce alcohol-related suicide.

Genetic and environmental influences on the progression from alcohol use disorder to alcohol-related medical conditions
2021
Ingår i: Alcoholism: Clinical and Experimental Research. - : Wiley. - 0145-6008 .- 1530-0277. ; 45:12, s. 2528-2535
Tidskriftsartikel (refereegranskat) abstract
Background: Medical conditions related to alcohol use disorders (AUD) represent a substantial public health concern. However, only a subset of individuals with AUD develop these conditions and the extent to which genetic and environmental factors that are shared with AUD, versus those distinct from it, contribute to this progression has not yet been determined. Methods: Using data from Swedish national registries for a cohort born from 1932 to 1970 (N = 1,319,214, 48.9% women), we conducted twin-sibling biometric model fitting to examine the genetic and environmental sources of variance that contribute to the liability to alcohol-related medical conditions (AMC). Progression to AMC, determined using medical registry data, was contingent on an AUD registration, which was determined using medical and criminal registry data. Results: We identified AUD registrations in 3.2% of women and 9.2% of men. Among individuals with an AUD registration, 14.4% of women and 15.4% of men had an AMC registration. In the final models, we constrained the beta pathway from AUD to AMC and the genetic and unique environmental paths to be equal across sexes. The beta path was estimated at 0.59. AMC was modestly heritable in women (A = 0.32) and men (A = 0.30). The proportion of total heritability unique to AMC was 39.6% among women and 41.3% among men. A higher proportion of total environmental variance was unique to AMC: 76.7% for women and 77.2% for men. In a sensitivity analysis limited to liver-related AMC, we observed similar results, with a slightly lower beta path from AUD to AMC (0.46) and higher proportions of AMC-specific genetic (70.0% in women; 71.7% in men) and environmental (84.5% in both sexes) variance. Conclusions: A moderate-to-substantial proportion of genetic and environmental variance that contributes to AMC risk is not shared with AUD, underscoring the need for additional gene identification efforts for AMC. Furthermore, the prominent influence of environmental factors specific to AMC provides a promising area for the identification of prevention targets. We did not observe significant sex differences in the etiology of AMC, although follow-up is warranted in other well-powered studies.

Socioeconomic sequelae of drug abuse in a Swedish national cohort
2020
Ingår i: Drug and Alcohol Dependence. - : Elsevier BV. - 0376-8716. ; 212
Tidskriftsartikel (refereegranskat) abstract
Background: Drug abuse is frequently associated with negative sequelae such as reduced socioeconomic functioning. The extent to which these associations are attributable to a causal role of the disorder versus confounding factors that increase risk for both drug abuse and negative socioeconomic outcomes is unclear. Methods: Drug abuse cases were identified using Swedish national medical, pharmacy, and criminal registers. Applying Cox proportional hazard models, we tested the association between drug abuse and four outcomes: early retirement, social assistance, unemployment, and income at age 50. We used co-relative models to determine whether familial confounding factors accounted for observed associations. Results: In models adjusted for birth year, education, and early onset externalizing behavior, drug abuse was strongly associated with early retirement (hazard ratios [HR] = 5.13–6.28), social assistance (HR = 6.74–7.89), and income at age 50 (beta = −0.19 to −0.12); it was more modestly associated with unemployment (HR = 1.05–1.20). For social assistance and income (both sexes), and early retirement (women only), a model in which the association was partly attributable to familial factors fit the data well; residual associations support a partially causal role of drug abuse. For unemployment and early retirement among men, there was little evidence of familial confounding. Conclusions: The negative socioeconomic sequelae of drug abuse are likely due in part to familial confounding factors in conjunction with a causal relationship and/or unmeasured non-familial confounders. Relative contributions from distinct mechanisms differed across socioeconomic outcomes, which could have implications for understanding the potential impact of prevention and intervention efforts.

Alcohol use disorder and mortality across the lifespan : a longitudinal cohort and co-relative analysis
2016
Ingår i: JAMA Psychiatry. - : American Medical Association (AMA). - 2168-622X. ; 73:6, s. 575-581
Tidskriftsartikel (refereegranskat) abstract
Importance: Excess alcohol consumption and alcohol use disorders (AUDs) are associated with substantially increased mortality. Efforts to reduce this toll require an understanding of their causes. Objective: To clarify the degree to which the excess mortality associated with AUDs arises (1) from the predispositions of the person who develops AUD (and which would likely be shared by close relatives) and (2) as a direct result of AUD itself. Design, Setting, and Participants: A prospective cohort and co-relative design study involving all individuals born in Sweden from 1940 to 1965 who had neither died nor migrated prior to 1973 or age 15 years (N = 2 821 036). They were followed up from January 1, 1973, until December 31, 2010. Alcohol use disorder was assessed from medical, criminal, and pharmacy registries. Half-siblings, full-siblings, and monozygotic twin pairs discordant for AUD were obtained from the Multi-Generation and Twin Register. Main Outcome and Measure: Death obtained from the Swedish Death registry. Results: Our cohort (1 447 887 males and 1 373 149 females) included 131 895 males and 42 163 females registered with AUD. The mean (SD) age at first AUD registration was 39 (13.4) years.We ascertained 127 347 and 76 325 deaths in the male and female subsamples, respectively. Controlling for sex, educational status, and year of birth, the mortality hazard ratio associated with AUD was 5.83 (95%CI, 5.76-5.90) and varied-with an inverted U-shaped function-by age. Examining the AUD-mortality association in the general population and in relative pairs discordant for AUD exposure demonstrated substantial familial confounding in early to mid-adulthood: the AUD-associated mortality hazard ratio was much lower in discordant close relatives than in the general population. In middle to late adulthood, evidence for familial confounding decreased with increasing evidence for a direct effect of AUD on elevated mortality. In the oldest age group (65-70 years), the mortality hazard ratios were similar across the population and all relative pairs, suggesting that the excess mortality was largely a result of having AUD. Adding years since onset of AUD to the model showed that both increasing age and increasing years of duration of AUD contributed to the reduction of familial confounding in the association between AUD and elevated mortality. Conclusions and Relevance: Excess mortality associated with AUD arises both from the predispositions of the person who develops AUD and the direct result of having AUD. The effect of predisposition is more prominent early in the life course and in the early years of AUD. The direct effect of AUD becomes progressively more important later in life and with longer duration of AUD. These results have implications for interventions seeking to reduce the elevated AUD-associated mortality.
