Prospective associations between joint categories of physical activity and insomnia symptoms with onset of poor mental health in a population-based cohort

Background:Physical inactivity and insomnia symptoms are independently associated with increased risk of depression and anxiety;however,few studies jointly examine these risk factors.This study aimed to prospectively examine the joint association of physical activity(PA)and insomnia symptoms with onset of poor mental health in adults.Methods:Participants from the 2013 to 2018 annnual waves of the Household Income and Labour Dynamics in Australia panel study who had good mental health(Mental Health Inventory-5>54)in 2013,and who completed at least 1 follow-up survey(2014-2018),were included(n=10,977).Poor mental health(Mental Health Inventory-5≤54)was assessed annually.Baseline(2013)PA was classified as high/moderate/low,and insomnia symptoms(i.e.,trouble sleeping)were classified as no insomnia symptoms/insomnia symptoms,with 6 mutually exclusive PAinsomnia symptom groups derived.Associations of PA-insomnia symptom groups with onset of poor mental health were examined using discrete-time proportional-hazards logit-hazard models.Results:There were 2322 new cases of poor mental health(21.2%).Relative to the high PA/no insomnia symptoms group,there were higher odds(odds ratio and 95%confidence interval(95%CI))of poor mental health among the high PA/insomnia symptoms(OR=1.87,95%CI:1.57-2.23),moderate PA/insomnia symptoms(OR=1.93,95%CI:1.61-2.31),low PA/insomnia symptoms(OR=2.33,95%CI:1.96-2.78),and low PA/no insomnia symptoms(OR=1.14,95%CI:1.01-1.29)groups.Any level of PA combined with insomnia symptoms was associated with increased odds of poor mental health,with the odds increasing as PA decreased.Conclusion:The se findings highlight the potential benefit of interventions targeting both PA and insomnia symptoms for promoting mental health.

Absolute cardiovascular risk assessment by Australian early-career general practitioners: a cross-sectional study

Objective To determine the prevalence and associations of general practice registrars’performing absolute cardio-vascular risk(ACVR)assessment(ACVRa).Design A cross-sectional study employing data(2017–2018)from the Registrar Clinical Encounters in Training project,an ongoing inception cohort study of Australian GP registrars.The outcome measure was whether an ACVRa was performed.Analyses employed univariable and multivariable regression.Analysis was conducted for all patient problems/diagnoses,then for an‘at-risk’population(specific problems/diagnoses for which ACVRa is indicated).Setting Three GP regional training organisations(RTOs)across three Australian states.Participants GP registrars training within participating RTOs.Results 1003 registrars(response rate 96.8%)recorded details of 69105 problems either with Aboriginal and/or Torres Strait patients aged 35 years and older or with non-Indigenous patients aged 45 years and older.Of these problems/diagnoses,1721(2.5%(95%CI 2.4%to 2.6%))involved an ACVRa.An ACVRa was‘plausibly indicated’in 10384 problems/diagnoses.Of these,1228(11.8%(95%CI 11.2%to 12.4%))involved ACVRa.For‘all problems/diagnoses’,on multivariable analysis female gender was associated with reduced odds of ACVRa(OR 0.61(95%CI 0.54 to 0.68)).There was some evidence for Aboriginal and/or Torres Strait Islander people being more likely to receive ACVRa(OR 1.40(95%CI 0.94 to 2.08),p=0.10).There were associations with variables related to continuity of care,with reduced odds of ACVRa:if the patient was new to the registrar(OR 0.65(95%CI 0.57 to 0.75)),new to the practice(OR 0.24(95%CI 0.15 to 0.38))or the problem was new(OR 0.68(95%CI 0.59 to 0.78));and increased odds if personal follow-up was organised(OR 1.43(95%CI 1.24 to 1.66)).For‘ACVRa indicated’problems/diagnoses,findings were similar to those for‘all problems/diagnoses’.Association with Aboriginal and/or Torres Strait Islander status,however,was significant at p<0.05(OR 1.60(95%CI 1.04 to 2.46))and association with female gender was attenuated(OR 0.88(95%CI 0.77 to 1.01)).Conclusion Continuity of care is associated with registrars assessing ACVR,reinforcing the importance of care continuity in general practice.Registrars’assessment of an individual patient’s ACVR is targeted to patients with individual risk factors,but this may entail ACVRa underutilisation in female patients and younger age groups.

Specificity of early-career general practitioners’problem formulations in patients presenting with dizziness:a cross-sectional analysis

Objectives Dizziness is a common and challenging clinical presentation in general practice.Failure to determine specific aetiologies can lead to significant morbidity and mortality.We aimed to establish frequency and associations of general practitioner(GP)trainees’(registrars’)specific vertigo provisional diagnoses and their non-specific symptomatic problem formulations.Design A cross-sectional analysis of Registrar Clinical Encounters in Training(ReCEnT)cohort study data between 2010 and 2018.ReCEnT is an ongoing,prospective cohort study of registrars in general practice training in Australia.Data collection occurs once every 6 months midtraining term(for three terms)and entails recording details of 60 consecutive clinical consultations on hardcopy case report forms.The outcome factor was whether dizziness-related or vertigo-related presentations resulted in a specific vertigo provisional diagnosis versus a non-specific symptomatic problem formulation.Associations with patient,practice,registrar and consultation independent variables were assessed by univariate and multivariable logistic regression.Setting Australian general practice training programme.The training is regionalised and delivered by regional training providers(RTPs)(2010-2015)and regional training organisations(RTOs)(2016-2018)across Australia(from five states and one territory).Participants All general practice registrars enrolled with participating RTPs or RTOs undertaking GP training terms.Results 2333 registrars(96%response rate)recorded 1734 new problems related to dizziness or vertigo.Of these,546(31.5%)involved a specific vertigo diagnosis and 1188(68.5%)a non-specific symptom diagnosis.Variables associated with a non-specific symptom diagnosis on multivariable analysis were lower socioeconomic status of the practice location(OR 0.94 for each decile of disadvantage,95%CIs 0.90 to 0.98)and longer consultation duration(OR 1.02,95%CIs 1.00 to 1.04).A specific vertigo diagnosis was associated with performing a procedure(OR 0.52,95%CIs 0.27 to 1.00),with some evidence for seeking information from a supervisor being associated with a non-specific symptom diagnosis(OR 1.39,95%CIs 0.92 to 2.09;p=0.12).Conclusions Australian GP registrars see dizzy patients as frequently as established GPs.The frequency and associations of a non-specific diagnosis are consistent with the acknowledged difficulty of making diagnoses in vertigo/dizziness presentations.Continuing emphasis on this area in GP training and encouragement of supervisor involvement in registrars’diagnostic processes is indicated.
