Not in Education Employment or Training (NEET) Trajectories Between Adolescence and Early Adulthood and Subsequent Mental Health

Importance: Not in Education Employment or Training (NEET) in youth is associated with poorer mental health and is increasing. Prior work has treated NEET as a single status, obscuring whether repeated disengagement carries cumulative later mental health risk. Objective: Estimate associations between the number of NEET occasions between ages 16 and 33 years and depression, anxiety, wellbeing and a recent suicide attempt at age 33. Secondary analysis explored associations between age of first NEET and type of NEET with outcomes. Design, Setting and Participants: 3,792 individuals from a longitudinal population-based birth cohort (Avon Longitudinal Study of Parents and Children), followed from birth to age 33. Exposure: Number of NEET occasions, modelled as a count and as categories (0, 1, 2, 3+), the age of first NEET occasion and the type of NEET (single, sustained or recurrent occasions). Main Outcomes and Measures: Depression (SMFQ), anxiety (GAD-7), lower life satisfaction (SWLS), recent suicide attempt. Results: Each additional NEET occasion was associated with higher odds of depression (OR: 1.29 [95%CI: 1.18, 1.40], PFDR=3.04x10-08), anxiety (1.21 [1.11, 1.32], PFDR=7.54x10-05), lower life satisfaction (1.53 [1.40, 1.68], PFDR=2.26x10-19) and a recent suicide attempt (1.51 [1.28, 1.77], PFDR=1.17x10-06). Relative to never being NEET, odds of depression were higher at three or more NEET occasions (2.68 [1.74, 4.11], PFDR=1.76x10-05), while lower life satisfaction (5.97 [3.93, 9.05], PFDR=4.94x10-16) and a recent suicide attempt (7.40 [3.08, 17.80], PFDR=1.18x10-05) increased stepwise from one to three or more occasions. Associations were strongest for first NEET at ages 25 to 33, though first NEET between ages 16 to 20 was also associated with a recent suicide attempt (4.49 [2.20, 9.17], PFDR=6.51x10-05). Among those ever NEET, sustained and recurrent NEET showed little association beyond a single occasion, except for lower life satisfaction (2.60 [1.68, 4.02], PFDR=0.0001) and a recent suicide attempt (3.16 [1.23, 8.08], PFDR=0.042). Conclusions and Relevance: Repeated NEET status across adolescence and early adulthood was associated with poorer mental health at age 33, with dose-dependent associations for depression, life satisfaction and a recent suicide attempt. Our findings suggest that preventing repeated NEET and identifying mental health need at the point of first NEET entry, may be important targets for intervention and/or prevention of later poorer mental health.
