Knowledge about concurrent substance use and other risk behaviors - as well as their determinants - in the general population is insufficient.

To investigated socio-demographic, health status, and lifestyle determinants of habit-forming risk behaviors among French men and women.

We analyzed data collected in 2021–2022 from 32,622 participants (74.5% female; mean age=57.9±14.2 years) of the NutriNet-Santé web-cohort who had completed the Alcohol Use Disorders Identification Test, the 12-item Cigarette Dependence Scale, the modified Yale Food Addiction Scale 2.0, and the Internet Addiction Test. Using established cutoff values, participants were first split into 2 groups (Yes/No) for each risk behavior (alcohol use disorders, nicotine dependence, food addiction, and Internet addiction) and then placed into 3 groups (no risk behavior, 1 risk behavior (reference), and ≥2 risk behaviors) before fitting polytomous logistic regression models according to sex.

Younger age (Odds Ratio: ORmale=2.07; ORfemale=2.04), self-perceived poor health (ORmale=2.06; ORfemale=1.61), having obesity (OR=1.56; ORfemale=1.30), lack of affection during childhood (ORmale=1.56; ORfemale=1.39), and a lifetime prevalence or medication use for a mental disorder (ORmale=1.73; ORfemale=1.38) were significantly associated with having ≥2 versus 1 habit-forming risk behavior in both sexes (all p<0.05). Results for experiencing current financial difficulties (ORfemale=1.34), self-perceived poor dietary quality (ORfemale=3.23), being underweight (ORfemale=1.58) and overweight (ORfemale=1.30) were significant only in females (all p<0.05). The same factors plus current e-cigarette use (ORmale=0.54; ORfemale=0.77) in both sexes, having a higher educational attainment (ORfemale=0.75), being physically active at work (ORfemale=0.78) in females were inversely associated with having none versus 1 risk behavior (all p<0.05).

To our knowledge, this is the first study to explore determinants of concurrent habit-forming risk behaviors among men and women in a large, population-based study. The findings could serve as impetus for future research in this domain and ultimately help guide addiction prevention efforts.

We aimed to study the influence of age, in normal hearing individuals, on: the masking level difference test, the speech recognition in noise test, the transient evoked otoacoustic emissions test, and the contralateral transient evoked otoacoustic emission suppression test. We also aimed to research the effect of age when using these tests to evaluate the central auditory nervous system.

Transient evoked otoacoustic emissions and contralateral transient evoked otoacoustic emission suppression were measured in all subjects. Subjects also underwent masking level difference and speech recognition in noise tests.

We found a decrease in transient evoked otoacoustic emission amplitudes, speech recognition in noise scores and hearing thresholds with age. We also found that higher masking level difference values were associated with lower speech recognition in noise scores and contralateral transient evoked otoacoustic emission suppression values.

We conclude that decreasing speech recognition in noise scores are associated with decreasing contralateral transient evoked otoacoustic emission supression values. This effect may be related to medial efferent system dysfunction.
