Parental alcohol intoxication and adverse health outcomes among offspring. A 4-year follow up HUNT study among 2399 Norwegian adolescents

Parents' drinking, childhood hangover? Parental alcohol use, subjective health complaints and perceived stress among Swedish adolescents aged 10-18 years

BACKGROUND

Alcohol abuse is not only harmful to the consumer but may also negatively impact individuals in the drinker's social environment. Alcohol's harm to others is vital to consider when calculating the true societal cost of alcohol use. Children of parents who have alcohol use disorder tend to have an elevated risk of negative outcomes regarding, e.g., health, education, and social relationships. Research on the general youth population has established a link between parental drinking and offspring alcohol use. However, there is a lack of knowledge regarding other outcomes, such as health. The current study aimed to investigate the associations between parental drinking and children's psychological and somatic complaints, and perceived stress.

METHODS

Data were derived from a nationally representative sample, obtained from the 2010 Swedish Level-of-Living survey (LNU). Parents and adolescents (ages 10-18) living in the same households were interviewed independently. The final study sample included 909 adolescents from 629 households. The three outcomes, psychological and somatic complaints and perceived stress, were derived from adolescents' self-reports. Parents' self-reports of alcohol use, both frequency and quantity, were used to categorise adolescents as having abstaining, low-consuming, moderate-drinking, or heavy-drinking parents. Control variables included adolescents' gender, age, family structure, and household socioeconomic status. Linear and binary logistic regression analyses were performed.

RESULTS

Parental heavy drinking was more common among adolescents living in more socioeconomically advantaged households and among adolescents living with two custodial parents or in reconstituted families. Adolescents with heavy-drinking parents reported higher levels of psychological and somatic complaints and had an increased likelihood of reporting stress, compared with those having moderate-drinking parents. These associations remained statistically significant when adjusting for all control variables.

CONCLUSION

The current study's results show that parental alcohol consumption is associated with poorer offspring adolescent health. Public health policies that aim to reduce parental drinking or provide support to these adolescents may be beneficial. Further studies investigating the health-related outcomes among young people living with heavy-drinking parents in the general population are needed to gain more knowledge about these individuals and to implement adequate public health measures.

Risk of somatic disease and mortality in individuals of parents with alcohol use disorder: a register-based cohort study

AIMS

To estimate the risks of 12 types of somatic disease-alcohol-related, blood, cancer, circulatory, digestive, endocrine and metabolic, genitourinary, infectious, musculoskeletal, nervous, respiratory and skin-in individuals with parental alcohol use disorder (AUD) versus a reference population, and to estimate the risks of all-cause mortality and of death from an alcohol-related cause.

DESIGN

Matched cohort study followed-up through nation-wide health registries. Cox proportional hazards models were used to estimate hazard ratios (HRs) with 95% confidence intervals (CIs).

SETTING

Denmark.

PARTICIPANTS

A total of 14 008 individuals born 1962-2003 of parents with AUD and 139 087 reference offspring randomly selected from the Danish Civil Registration System were followed from their 15th birthday and onward during 1970-2018. Follow-up time ranged between 2 423 955 and 3 208 366 person-years for somatic diseases and was 3 214 411 person-years for all-cause and alcohol-related mortality.

MEASUREMENTS

Information on somatic disease was obtained from the Danish National Patient Registry. Causes of death were obtained from the Danish Cause of Death Registry.

FINDINGS

Individuals of parents with AUD had a higher risk of alcohol-related diseases (HR = 2.70, 95% CI = 2.24-3.24) compared with the reference individuals. Higher HRs among individuals with parental AUD compared with reference individuals were also observed in all other somatic diseases except for cancer. All-cause mortality (HR = 1.80, 95% CI = 1.63-2.00) and alcohol-related mortality (HR = 3.28, 95% CI = 2.11-5.08) were higher among individuals of parents with AUD compared with the reference individuals. No significant differences were found in relation to the gender of either parents or offspring.

CONCLUSIONS

In Denmark, parental alcohol use disorder appears to predict alcohol-related and non-alcohol-related somatic morbidity and mortality in offspring.

Mortality in adult children of parents with alcohol use disorder: a nationwide register study

Research suggests that adult children of parents with harmful alcohol use are at increased risk for premature death. This national cohort study investigated mortality in adult children of parents with alcohol use disorder (AUD), adjusting for sociodemographic variables. The study used 1973 to 2018 data from Swedish national registers to compare mortality risk in children who had ≥ 1 parent with AUD (ICD-10 code F10 and its ICD-8 and ICD-9 equivalents) (n = 122,947) and those who did not (n = 2,298,532). A Cox regression model adjusted for year of birth, sex, parental education, and childhood loss of a parent was used. Before the age of 18 years, about 5% of children born in Sweden lived with ≥ 1 parent who had a clinical diagnosis of AUD. Overall mortality was higher in adult children of parents with AUD: hazard ratio (HR) 1.76, 95% confidence interval (CI) 1.71-1.82. Mortality remained elevated after adjustments for sociodemographic factors (HR 1.45, 95% CI 1.40-1.50). Children of parents with AUD had increased mortality from all investigated causes. The highest excess risk was for death from drug-related causes (excluding accidental poisonings) (HR 3.08, 95% CI 2.74-3.46). For most causes, mortality was higher if the mother had AUD than if the father had AUD. Patterns of mortality were similar in both sexes. This study provides evidence that parental AUD raises the risk of offspring mortality from preventable causes such as drug use, suicide (HR 2.16, 95% CI 1.98-2.36), accident (HR 2.00, 95% CI 1.87-2.13), and assault (HR 1.76, 95% CI 1.38-2.24).

Prevalence of Parental Alcohol Problems among a General Population Sample of 28,047 Norwegian Adults: Evidence for a Socioeconomic Gradient

The aim of the study presented here was to estimate the prevalence of parental alcohol problems during childhood in a general population of Norwegian adults, and to investigate associations between parental alcohol problems during childhood and lower socioeconomic status in adulthood. This cross-sectional study recruited 28,047 adults (≥18 years) to an online health survey (Norwegian Counties Public Health Surveys). We evaluated demographic and socioeconomic measures and responses to a shortened version of the Children of Alcoholics Screening Test (CAST-6) scale to assess whether respondents perceived parental alcohol consumption during childhood as problematic. Respondents reported parental alcohol problems at a rate of 15.6%, but the experience was more prevalent among adults with a low education (20.0%), compared to those with intermediate (16.4%) or high educations (13.8%, χ2(2) = 87.486, p < 0.001), and it was more common among respondents with low economic capabilities (21.1%) compared to those with middle/high capabilities (14.2%, χ2(1) = 162.089, p < 0.001). Parental alcohol problems were most prevalent among respondents that received welfare benefits (24.5%). Multivariable logistic regression analyses revealed associations between parental alcohol problems and low socioeconomic status in adulthood; odds ratios (95% confidence intervals) ranged from 1.33 (1.25-1.42) to 1.89 (1.72-2.06). From a public health perspective, children who grow up with parental alcohol problems should be reached through both universal and selective interventions.
