Undiagnosed depression, persistent depressive symptoms and seeking mental health care: analysis of immigrant and non-immigrant participants of the Canadian Longitudinal Study of Aging.

ABSTRACT: AIMS:Early diagnosis and treatment of depression are associated with better prognosis. We used baseline data of the Canadian Longitudinal Study on Aging (2012-2015; ages 45-85 years) to examine differences in prevalence and predictors of undiagnosed depression (UD) between immigrants and non-immigrants at baseline and persistent and/or emerging depressive symptoms (DS) 18 months later. At this second time point, we also examined if a mental health care professional (MHCP) had been consulted. METHODS:We excluded individuals with any prior mood disorder and/or current anti-depressive medication use at baseline. UD was defined as the Center for Epidemiological Studies Depression 10 score ?10. DS at 18 months were defined as Kessler 10 score ?19. The associations of interest were examined in multivariate logistic regression models. RESULTS:Our study included 4382 immigrants and 18 620 non-immigrants. The mean age (standard deviation) in immigrants was 63 (10.3) years v. 65 (10.7) years in non-immigrants and 52.1% v. 57.1% were male. Among immigrants, 12.2% had UD at baseline of whom 34.2% had persistent DS 18 months later v. 10.6% and 31.4%, respectively, among non-immigrants. Female immigrants were more likely to have UD than female non-immigrants (odds ratio 1.50, 95% confidence interval 1.25-1.80) but no difference observed for men. The risk of persistent DS and consulting an MHCP at 18 months did not differ between immigrants and non-immigrants. CONCLUSIONS:Female immigrants may particularly benefit from depression screening. Seeking mental health care in the context of DS should be encouraged.

Project description:OBJECTIVE:To identify the factors associated with 12-month mental health service use in primary care patients with depressive symptoms. DESIGN:Cross-sectional followed by 12-month cohort study. SETTING AND PARTICIPANTS:10?179 adult patients were recruited from the waiting rooms of 59 primary care clinics across Hong Kong to complete a questionnaire which screened for depression. 518 screened-positive participants formed the cohort and were telephoned at 3, 6 and 12?months to monitor mental health service use. PRIMARY AND SECONDARY OUTCOMES:??Help-seeking preferences; ??Intention to seek help from a healthcare professional; ? 12-month mental health service use. RESULTS:At baseline, when asked who they would seek help from if they thought they were depressed, respondents preferred using friends and family (46.5%) over a psychiatrist (24.9%), psychologist (22.8%) or general practitioner (GP; 19.9%). The presence of depressive symptoms was associated with a lower intention to seek help from family and friends but had no effect on intention to seek help from a healthcare professional. Over 12?months, 24.3% of the screened-positive cohort reported receiving services from a mental health professional. Factors associated with service use included identification of depression by the GP at baseline, having a past history of depression or other mental illness, and being a public sector patient. Having a positive intention to seek professional help or more severe depressive symptoms at baseline was not associated with a greater likelihood of receiving treatment. CONCLUSIONS:Mental health service use appears to be very low in this setting with only one in four primary care patients with depressive symptoms receiving treatment from a psychiatrist, GP or psychologist over a year. To help reduce the burden of illness, better detection of depressive disorders is needed especially for patients who may be undertreated such as those with no prior diagnosis of depression and those with more severe symptoms.

Project description:BackgroundHealth risk assessments (HRAs), which often screen for depressive symptoms, are administered to millions of employees and health plan members each year. HRA data provide an opportunity to examine longitudinal trends in depressive symptomatology, as researchers have done previously with other populations.ObjectiveThe primary research questions were: (1) Can we observe longitudinal trajectories in HRA populations like those observed in other study samples? (2) Do HRA variables, which primarily reflect modifiable health risks, help us to identify predictors associated with these trajectories? (3) Can we make meaningful recommendations for population health management, applicable to HRA participants, based on predictors we identify?MethodsThis study used growth mixture modeling (GMM) to examine longitudinal trends in depressive symptomatology among 22,963 participants in a Web-based HRA used by US employers and health plans. The HRA assessed modifiable health risks and variables such as stress, sleep, and quality of life.ResultsFive classes were identified: A "minimal depression" class (63.91%, 14,676/22,963) whose scores were consistently low across time, a "low risk" class (19.89%, 4568/22,963) whose condition remained subthreshold, a "deteriorating" class (3.15%, 705/22,963) who began at subthreshold but approached severe depression by the end of the study, a "chronic" class (4.71%, 1081/22,963) who remained highly depressed over time, and a "remitting" class (8.42%, 1933/22,963) who had moderate depression to start, but crossed into minimal depression by the end. Among those with subthreshold symptoms, individuals who were male (P<.001) and older (P=.01) were less likely to show symptom deterioration, whereas current depression treatment (P<.001) and surprisingly, higher sleep quality (P<.001) were associated with increased probability of membership in the "deteriorating" class as compared with "low risk." Among participants with greater symptomatology to start, those in the "severe" class tended to be younger than the "remitting" class (P<.001). Lower baseline sleep quality (P<.001), quality of life (P<.001), stress level (P<.001), and current treatment involvement (P<.001) were all predictive of membership in the "severe" class.ConclusionsThe trajectories identified were consistent with trends in previous research. The results identified some key predictors: we discuss those that mirror prior studies and offer some hypotheses as to why others did not. The finding that 1 in 5 HRA participants with subthreshold symptoms deteriorated to the point of clinical distress during succeeding years underscores the need to learn more about such individuals. We offer additional recommendations for follow-up research, which should be designed to reflect changes in health plan demographics and HRA delivery platforms. In addition to utilizing additional variables such as cognitive style to refine predictive models, future research could also begin to test the impact of more aggressive outreach strategies aimed at participants who are likely to deteriorate or remain significantly depressed over time.

Project description:Depressive symptoms and binge eating are both prevalent in weight management populations and may be associated with reduced benefit from behavioral weight loss, including higher attrition, more perceived barriers, lower weight loss, and increased weight regain. These two potential risk factors for poor behavioral weight loss outcomes may also be associated with each other as depressive symptoms may trigger binge eating, and binge eating-related distress could increase depressive symptoms. The depressive symptom-binge eating link has not been well studied in weight management samples, and psychological processes involved in this relationship have not yet been elucidated. Psychological flexibility, an individual's ability to be connected with and conscious of the present moment and to engage in values-consistent behavior even in the presence of difficult internal experiences, may be one psychological process that changes the depressive symptom-binge eating relationship. High psychological flexibility may be a protective factor in the association of depressive symptoms with binge eating. This study examined the relationship between depressive symptom and binge eating and a potential interactive role of psychological flexibility. Participants (N = 468, 76% female) completed self-report questionnaires of binge eating, depressive symptoms, and psychological flexibility at baseline prior to initiating behavioral weight loss. Depressive symptoms were positively associated with binge eating (B = 1.00, p < 0.001). Psychological flexibility had an interactive role (B = -0.03, p = 0.005). Among participants with minimal to mild depressive symptoms, those with higher psychological flexibility had less severe binge eating. Findings suggest that psychological flexibility may be a protective factor in the association between depressive symptoms and binge eating in the majority of individuals initiating behavioral weight loss. Psychological flexibility is a psychological process to consider targeting for enhancing efficacy of weight loss treatment, especially among individuals with minimal to mild depressive symptoms and binge eating behavior.
