IQ in high school as a predictor of midlife alcohol drinking patterns.

AIMS: The aim of the present study was to assess the relationship between adolescent IQ and midlife alcohol use and to explore possible mediators of this relationship. METHODS: Study data were from 6300 men and women who participated in the Wisconsin Longitudinal Study of high-school students graduating in 1957. IQ scores were collected during the participants' junior year of high school. In 2004, participants reported the number of alcoholic beverages consumed (past 30 days) and the number of binge-drinking episodes. A multinomial logistic regression was conducted to determine the relationship between adolescent IQ and future drinking pattern (abstainer, moderate drinker, or heavy drinker), and Poisson regression was used to examine the number of binge-drinking episodes. Two mediators-income and education-were also explored. RESULTS: Every one-point increase in IQ score was associated with a 1.6% increase in the likelihood of reporting moderate or heavy drinking as compared to abstinence. Those with higher IQ scores also had significantly fewer binge-drinking episodes. Household income, but not education, partially mediated the relationship between IQ and drinking pattern. CONCLUSIONS: The present study suggests that higher adolescent IQ may predict a higher likelihood of moderate or heavy drinking in midlife, but fewer binge-drinking episodes. The study also suggests that this relationship is mediated by other psychosocial factors, specifically income, prompting future exploration of mediators in subsequent studies.

The relationship between alcohol consumption and amygdala volume in a community-based sample.

Most prior studies have reported decreased amygdala volume in those with a history of alcohol use disorder. Decreased amygdala volume associated with alcohol use disorder may be related to an increased risk of addiction and relapse. However, the relationship between amygdala volume and a broad range of alcohol consumption is largely unexplored. The present cross-sectional analysis investigates the relationship between amygdala volume and self-reported alcohol consumption in participants of the Dallas Heart Study, a community-based study of Dallas County, Texas residents. Brain imaging and survey data from participants (n = 2023) were obtained, and multiple linear regressions were performed with the average amygdala volume as the dependent variable and drinking status, drinking risk, drinks per week, and binge drinking as independent variables. Drinking risk was categorized such that low-risk constituted ≤ 14 drinks per week in men and ≤ 7 drinks per week in women, while > 14 drinks per week in men and > 7 drinks per week in women constituted high-risk. Age, sex, intracranial volume, body mass index, education, and Quick Inventory of Depressive Symptomatology-Self Report score were included in all models as covariates. No statistically significant (p ≤ .05) associations were observed between self-reported alcohol consumption and amygdala volume. The present study suggests non-significant relationships between self-reported alcohol consumption and amygdala volume when controlling for relevant demographic factors in a large, community-based sample.

Contribution of caregiver and child anxiety and depressive symptoms to child asthma-related quality of life.

BACKGROUND: Depression and anxiety negatively affect asthma-related quality of life (QoL). Yet, little is known regarding mood and asthma-related factors that best uniquely explain asthma-related QoL in children. OBJECTIVE: This cross-sectional study evaluated the unique variance explained by caregiver and child depressive and anxiety symptom severity in child asthma-related QoL, apart from that explained by demographics and asthma control. METHODS: Children aged 7 to 17 years with asthma (n = 205) and their caregivers with major depressive disorder were included. A 3-stage hierarchical linear regression analysis was conducted with the Pediatric Asthma Quality of Life Questionnaire total scores considered as the outcome. Predictors included demographic characteristics (stage 1); asthma control assessed by the Asthma Control Test (stage 2); and caregiver depression and anxiety (Hamilton Rating Scale for Depression and the Spielberger State/Trait Anxiety Scale) and child depression and anxiety (Children's Depression Inventory and the Screen for Child Anxiety-Related Disorders) (stage 3). RESULTS: Demographic characteristics accounted for only 5.5% of the Pediatric Asthma Quality of Life Questionnaire scores. Asthma control significantly increased variance explained in QoL to 32.6%, whereas caregiver and child depression and anxiety symptoms significantly increased variance explained to 42.6%. Child anxiety was found to uniquely explain the largest proportion of variance in QoL (rs2 = 0.584). CONCLUSION: After adjusting variance in QoL for demographic characteristics and asthma control, caregiver and child depression and anxiety measures significantly increased the proportion of variance explained in a child's asthma-related QoL. In addition to better asthma control, child and caregiver depression and anxiety should be addressed to increase child asthma-related QoL.

The dynamic buffering of social support on depressive symptoms and cancer worries in patients seeking cancer genetic counseling.

PURPOSE: Social support is a crucial protective factor against psychological concerns in patients with cancer. However, there is limited knowledge regarding the differential impacts of social support on cancer worries and depressive symptoms in patients undergoing genetic counseling for hereditary cancer. The current study utilized a high-volume database from a multi-site cancer genetics clinic to assess the impact of perceived social support on depressive symptoms and cancer worries among patients of different age groups (young versus older patients) and diagnosis status (diagnosed survivors versus undiagnosed). METHODS: 6,666 patients completed brief assessments of depressive symptoms, cancer worries, social support, and demographic questionnaires as part of routine clinical care between October 2016 and October 2020. Logistics and moderated regression were used to analyze the relationships between social support, depressive symptoms, and cancer worries. RESULTS: Increased social support was associated with fewer depressive symptoms and fewer cancer worries across all patients. Social support mitigated depressive symptoms most significantly for young adult patients with and without cancer. Social support mitigated cancer worries most significantly for young adults with cancer and older adults without cancer. CONCLUSIONS: While results were mixed, general findings upheld original hypotheses. Social support buffered depressive symptoms and cancer worries differentially for patients of different ages and different disease status. IMPLICATIONS FOR CANCER SURVIVORS: Social support groups are beneficial for all patients and should be emphasized by cancer clinics. However, increasing patient-tailored and age-appropriate support networks will be crucial for managing depression and cancer worries for high-risk survivors: young adults with cancer.

Severe Multiple Drug Intolerance Syndrome in Fibromyalgia and Irritable Bowel Syndrome.

BACKGROUND: Multiple drug intolerance syndrome (MDIS) describes patients with multiple nonimmunologically mediated adverse reactions to medications. Patients with more than 10 medication intolerance labels are considered to have severe MDIS. There is overlap in the characteristics of patients with MDIS and fibromyalgia and irritable bowel syndrome (IBS). Severe MDIS can limit treatment options in this already complex patient group. OBJECTIVE: This study assessed the prevalence of severe MDIS in patients with fibromyalgia and IBS and its associated risk factors. METHODS: A retrospective chart review identified patients diagnosed with fibromyalgia or IBS who had been seen at a large academic center from August 2019 to July 2020. Exact birthdate- and sex-matched controls who had been seen within the same time frame were selected at random. Listed drug intolerance data and patient characteristics were then analyzed with logistic regression and χ2 testing. RESULTS: Patients with fibromyalgia and IBS were 12 and 3 times more likely to have severe MDIS compared with controls, respectively. Severe MDIS was associated with polypharmacy in both groups. Opiates were the most frequently reported drug intolerance across all participants. Although patients with IBS more often reported gastrointestinal symptoms as adverse reactions, individuals with fibromyalgia did not more frequently report pain or behavioral changes as adverse reactions. CONCLUSIONS: There was an increased rate of severe MDIS in patients diagnosed with fibromyalgia and IBS. Additional studies are needed to better understand the morbidity of MDIS and how it can best be managed in patients with fibromyalgia and IBS.
