Social context of drinking among older adults: Relationship to alcohol and traffic risk behaviors

Unveiling the dynamics of social engagement and subjective health in older adults: A gendered perspective

OBJECTIVES

As populations age globally, understanding the dynamics that influence the well-being of older individuals become increasingly crucial. The research employs a comprehensive approach to unravel the multifaceted interplay between social engagements and subjective health perceptions of older Indians, with a special focus on gender differences.

SUBJECTS AND METHODS

This study used data from the Longitudinal Aging Study in India (LASI) wave 1, 2017-18 with a total sample of 30,533 older adults aged 60 years and above. Bivariate analysis, chi-square tests and unadjusted and adjusted average marginal effects from logistic regression models were used to assess the relationship between social engagements and subjective health among older adults, stratified by gender.

RESULTS

The prevalence of poor health status decreased with higher frequency of social networks among both men (pp. (percentage point) = 6.1; CI (Confidence Interval): 10.6, 1.6) and women (pp. = 9.2; CI: 14.9, 3.4). The adjusted average marginal effects demonstrate that with an increase in the overall score of social engagement, the likelihood of poor health is almost reduced by half. For men, the prevalence of poor health was 9.8 pp. (95 % CI: 13.7, 5.8), while for women, it was 9.3 pp. (95 % CI: 15.2, 3.1).

CONCLUSION

Gendered perspectives unveil unique patterns, highlighting how societal expectations and roles assigned to each gender may influence the subjective health perceptions of older individuals. This study adds to the expanding knowledge base to enhance the well-being and fulfillment of aging populations, considering the complex interplay of social dynamics and gendered perspectives.

Mining patterns of near-crash events with and without secondary tasks

The engagement of secondary tasks, like using a phone or talking to passengers while driving, could introduce considerable risks to driving safety. This study utilizes a near-crash dataset extracted from a naturalistic driving study to explore the patterns of near-crash events with or without the involvement of secondary tasks as a surrogate approach to understand the impact of these behaviors on traffic safety. The dataset contains information about driver behaviors, such as secondary tasks, vehicle maneuvers, other conflict vehicles' maneuvers before and during near-crash events, and the driving environment. The patterns for near-crashes with or without the involvement of secondary tasks are mined by adopting the apriori association rule algorithm. Finally, the mined rules for the near-crash events with or without the involvement of the secondary tasks are analyzed and compared. The results demonstrate that near-crashes with the involvement of secondary tasks often occur with drivers in a relatively stable and presumably predictable environment, such as an interstate highway with a constant speed. This type of near-crash is highly associated with the leading vehicle's sudden slowing or stopping since there is no expectation of any interruptions for these drivers performing the secondary tasks. The most common evasive maneuver in this kind of emergency is braking. Near-crashes without the involvement of secondary tasks is often associated with lane-changing behavior and sideswipe incidents. With shorter reaction time and awareness of the driving environment, the drivers in this type of near-crash can often make more complex maneuvers, like braking and steering, to avoid a collision. Understanding the patterns of these two types of near-crash incidents could help safety researchers, traffic engineers, and even vehicle designers/engineers develop countermeasures for minimizing potential collisions caused by secondary tasks or improper lane changing behaviors.

Driver experiences with the alcohol ignition interlock: Comparing successful and poor performers

OBJECTIVES

The purpose of this investigation was to compare the drinking patterns and experiences (both positive and negative) among DUI offenders who had installed an ignition interlock. The association between those experiences and interlock performance as measured by the number of times they had a lockout, was also assessed.

METHODS

Over 300 DUI offenders who installed an interlock in the State of Florida were recruited and completed an on-line survey at the beginning and end of their interlock restriction. A record of the interlock performance data from each was downloaded and used to determine how many lockouts they experienced during their interlock restriction period. Offenders were defined into two groups; successful cases (having 0 or 1 lockout) or poor performers (have 2 or more lockouts). Chi-square and binary regressions were used to assess differences between groups.

RESULTS

Poor performers reported significantly more drinking and were more likely to drink in a context of emotional comfort, yet they were more likely to report positive experiences with the interlock, especially as to its ability to remind them to avoid another DUI by reducing their drinking and driving. No difference was found between these two groups for the interlock's ability to reduce drinking.

CONCLUSIONS

People with a more serious drinking pattern and who may be most at risk for recidivating may be more inclined to recognize the potential benefits of the interlock as a DUI preventive countermeasure. More research is needed to identify and influence high risk DUI offenders while on the interlock to increase its effectiveness once the interlock is removed.

Situational context and motives of alcohol use among graduate student drinkers

Extensive research has examined alcohol use context and motives among undergraduates, but less is known about where, when, and why graduate students drink. The current study aimed to describe the motives and situational context of graduate student alcohol use, identify demographic and program characteristics associated with alcohol use motives and context, and assess how alcohol use motives and context are associated with alcohol use behavior. A sample of master's and doctoral-level students who drank during the past month (n = 2091; 63% female) completed an online survey. An exploratory factor analysis yielded two situational context factors: drinking in social situations (e.g., with friends, at a bar) and non-social situations (e.g., alone, at home). Graduate students most frequently endorsed social and enhancement drinking motives. Results of multivariate linear regression models showed that age, sex, race/ethnicity, and international student, marital, parental, and employment status were all associated with motives and context. Drinking for enhancement and drinking to cope were the motives most strongly associated with increased alcohol quantity and frequency, respectively. Drinking in social contexts was positively associated with alcohol quantity and frequency, and drinking in non-social contexts was positively associated with alcohol use frequency but inversely related to alcohol quantity. Graduate students who drink for enhancement reasons and in social situations might be at increased risk for higher quantity alcohol use, or graduate students who drink for coping reasons and in non-social situations might be at increased risk for more frequent alcohol use. Future longitudinal research is needed to explore whether drinking in certain contexts and with certain motivations is predictive of alcohol problems during and after graduate school.
