Age at entry to UK military service and long-term mental health

Abstract: IntroductionIt has been suggested that ‘junior entry’ to the UK Armed Forces (prior to age 17.5 years) increases the risk of adverse mental health outcomes. We used data from a large cohort of veterans to examine long-term mental health outcomes in veterans by age at entry to the UK Armed Forces, compared with non-veterans.MethodsRetrospective cohort study of 78 157 veterans in Scotland, born between 1945 and 1995 and and 252 637 matched non-veterans, with up to 37 years follow-up, using Cox proportional hazar… Show more

“…15 Junior entrants were defined as personnel who entered service under 17.5 years of age, in a predominantly educational role. 16 Cox proportional hazard models were used to examine the association between veteran status and cumulative risk of suicide, using age as the time-dependent variable, age at death from suicide as the failure time, and age at death (from causes other than suicide) as the censor time. 17 Proportionality assumptions were tested using methodology based on Schoenfeld residuals.…”

“…In the existing studies on Chinese military personnel, demographic variables, such as age, gender, education level, and military rank, are significantly correlated with mental health symptoms (e.g., anxiety, social anxiety disorder) (61)(62)(63). Moreover, in relevant studies conducted in western countries, sociodemographic characteristics, such as race, ethnicity, marital status, and enlistment age, can all affect the mental health of military personnel (64)(65)(66). As such, future research would benefit from focusing on specific personnel categories to develop more targeted guidance for psychological services.…”
