Effects of genetic variants of ADH1B and ALDH2 and social network on continued alcohol drinking among young adolescents in Taiwan

Alcohol drinking and problems in young populations: the challenge in Asia

PURPOSE OF REVIEW

The current article reviews recent research (from 2016 onward) on drinking behaviors and alcohol-related problems among young people in Asia with an emphasis on population-based evidence.

RECENT FINDINGS

Recent evidence concerning underage drinking in Asia was limited to certain countries and societies with most data derived from cross-sectional surveys. Measures of alcohol drinking or problems were less sophisticated. The prevalence of recent alcohol drinking varies widely with the highest estimates reported in Hong Kong and Korea (∼21%). Certain emotional, behavioral, and cognitive characteristics have been linked with increased drinking behaviors, including internalizing or externalizing problems. Parents (or family) are the most studied predictors within the domain of socioenvironmental characteristics, whereas little attention has been paid to the macro environments (e.g., media, alcohol advertisement, and alcohol control policy/regulations).

SUMMARY

Research on underage drinking behaviors in Asia is urgently needed, particularly in some emerging markets. Follow-up studies with longitudinal measurements and large diverse samples will provide a better understanding of developmental stage-dependent and ever-changing macroenvironmental factors, as well as possible mechanisms.

Television viewing and alcohol advertising with alcohol expectancies among school-aged children in Taiwan

OBJECTIVES

This study is aimed to examine the strength of association between television watching and potential exposure to alcohol advertising with multidimensional alcohol expectancies in school-aged children.

METHODS

A total of 779 4th (age 10) and 768 6th (age 12) grade students were recruited from 17 public elementary schools in northern Taiwan in 2006, with two waves of follow-up at 6 months apart. Self-administered questionnaires were used to collect information concerning individual characteristics, parental attributes, past-week screen time, drinking behaviors, and alcohol expectancies. Data of aired alcohol advertisements at baseline were obtained from the Nielsen Media Research Advertising Information Services; parenting styles were ascertained from the 1st follow-up. Alcohol Expectancies Questionnaire-Children version was used to measure alcohol expectancies (AEs) at baseline and the 2nd follow-up.

RESULTS

Nearly 27% of students reported watching television for more than two hours per day and 58% watching television after 9 p.m. Dimension-related heterogeneity exists in the relationship between TV viewing and alcohol advertising with AEs. With statistical adjustment for covariates, spending more than two hours watching TV per day was associated with increased levels of positive AEs "Promoting Relaxation or Tension Reduction [PRTR]" (β=1.52, 95% CI=0.92, 2.12; p<0.001); the exposure to alcohol advertising was associated with decline in negative AEs "Deteriorated Cognitive and Behavioral Function" (e.g., >8.0 ads: β=-1.06, 95% CI=-1.66, -0.47, p<0.01).

CONCLUSIONS

Greater screen time is associated with elevated positive expectancies of PRTR and alcohol advertising exposure is linked with lowered negative expectancies in late childhood. School-based anti-underage drinking programs may consider integrating the media literacy curriculum.
