• Alcohol consumption and associated factors among people with diabetes mellitus: a multicentre institution-based cross-sectional study (2026) · Scientific Reports · doi

  In this study, alcohol consumption was measured via self-reported alcohol consumption behaviour, and self-reports tended to underestimate alcohol consumption due to recall bias. Since the study was performed at a health institution, diabetic patients who have severe alcohol use disorders may not visit the hospital. As an institution-based cross-sectional study, this work estimates prevalence and associations at a single point in time and therefore cannot establish causality or temporal sequence between factors and alcohol consumption. In addition, the outcome measurement tool (AUDIT, consider the past–12-month use) and other variables use different recall periods, introducing potential temporal misalignment.

• Cultural and intergenerational pathways between family alcohol use, trauma exposure, and probable PTSD in Taiwanese adolescents (2026) · Frontiers in Psychiatry · doi

  Several limitations must be acknowledged. First, the cross- sectional design precludes causal inference and limits the ability to establish causality between AU, trauma exposure, and posttrau- matic symptoms. While regression models utilize ‘predictors’ and ‘outcomes,’ these should be interpreted as measures of statistical association within a single point in time rather than evidence of a chronological causal chain. Consequently, the observed associations should not be interpreted as definitive causal pathways. Second, while the UCLA PTSD-RI is a validated screening tool, it provides a measure of probable PTSD based on symptom thresholds rather than a confirmed clinical diagnosis. Third, alcohol use was assessed via frequency-based self-reports consistent with prior Taiwanese research, yet the absence of measures for consumption quantity or binge drinking limits the construct validity and precision of this variable. Moreover, frequency alone may not fully distinguish between experimental, low-risk drinking and heavy episodic use, which is often more strongly linked to traumatic injury and PTSD. Consequently, our findings may represent a conservative estimate of the association between alcohol and trauma, as we were unable to isolate the specific effects of high-intensity drinking patterns. Fourth, the treatment of sexual trauma as a single aggregated category resulted in statistical imprecision and potential model insta- bility in some subgroups, as evidenced by very large odds ratios and wide confidence intervals. Fifth, our analytical model was primarily unidirectional, focusing on how alcohol use predicts trauma and PTSD. This leaves unexamined the bidirectional relationship—specif- ically the “self-medication” pathway where trauma exposure or post- traumatic symptoms may drive subsequent alcohol use. Sixth, unmeasured factors such as parental mental illness, genetic variants beyond ALDH2, or culturally specific traumas such as discrimination or community conflict may partially account for the observed associ- ations and warrant investigation in future longitudinal studies. Finally, although the dataset was collected in 2012, its relevance is sustained by recent national statistics from the Ministry of Health and Welfare (46) and the Child Welfare League Foundation (47) which indicate that adolescent suicide rates have reached 18.4%, with past trauma remaining a significant predictor of distress. the chronic 8-year life expectancy gap for Furthermore, Indigenous populations highlights that the structural and familial risk factors examined in this study—specifically alcohol-related pathways—remain a critical, unaddressed frontier in Taiwan. This is further supported by National Health Insurance (NHI) reports from 2024–2025, which highlight that alcohol-related illnesses and mortality continue to be disproportionately high in regions with large Indigenous populations.

• Alcohol-Attributable Fraction for Injury in the U.S. General Population: Data From the 2005 National Alcohol Survey (2008) · Journal of Studies on Alcohol and Drugs · cited 17× · doi

  Additional studies of alcohol and injury in general populations that take into account the intensity of exposure to alcohol before the event, as well as recall bias by eliciting data on the proximity of the event to the time of the respondent interview, are necessary for determining unbiased estimates of the attributable fraction of alcohol in injury morbidity.
