Despite the availability of effective treatments for late life depression, data indicate that only a small minority of adults over the age of 65 years with depression access any kind of care for emotional or mental health problems. Using data from the Canadian Community Health Survey (Cycle 1.1), we compared patterns of mental health service utilization among middle-aged (45-64 years), younger old (65-74 years), and older old (75 years and older) adults with and without depression and identified predictors associated with accessing different services (n=59,302). Compared to middle-aged adults with depression, individuals aged 65 and older with depression were less likely to report any mental health consultation in the past year and especially unlikely to report consulting with professionals other than a family physician. Age remained a significant predictor of mental health service utilization even after accounting for other relevant variables such as gender, marital status, years of education, depression caseness, and number of chronic medical conditions. Although the prevalence of depression is lower in older age groups, the present study provides compelling evidence that mental health services are particularly underutilized by depressed older adults.
Older adults are under-represented in studies of CCBT for depression.
Background: Adults aged 65 years and older stand to benefit from the accumulating wealth of Internet-based health resources, including online interventions to assist in the self-management of chronic health conditions. However, concerns have been expressed that lesser Internet use and familiarity among older adults may limit the utility of web-based health interventions in older age groups. As these interventions become more prevalent, it is important to understand older adults’ receptivity to using the Internet as a tool in managing healthcare. Objective: The purpose of the present study was to gauge the extent to which older primary care patients are receptive to using web-based health resources, and to explore how health-related Internet use may be related to patient characteristics such as age, income, and health and mental health status. Methods: We surveyed 50 adults aged 65 years and older in a Veterans Administration primary care clinic regarding: (1) Internet use for any purpose, (2) Internet use to obtain health or mental-related information, and (3) interest in using Internet-based interventions to address various health-related needs. A substantial proportion of respondents were in their 70s, 80s, and 90s, and many had multiple medical conditions. Results: Nearly three-quarters of older primary care patients in our sample were regular Internet users and over half had experience in using the Internet to search for health information. The majority of Internet users endorsed an interest in using web-based resources to manage various aspects of their health and mental healthcare. Conclusions: Our results support the conclusion that older primary care patients, including those among the oldest-old and those with multiple medical conditions, are amenable to using the Internet as a means of enhancing healthcare.
Numerical solutions to a model equation that describes cell population dynamics are presented and analyzed. A distinctive feature of the model equation (a hyperbolic partial differential equation) is the presence of delayed arguments in the time (t) and maturation (x) variables due to the nonzero length of the cell cycle. This transport like equation balances a linear convection with a nonlinear, nonlocal, and delayed reaction term. The linear convection term acts to impress the value of u(t,x=0) on the entire population while the death term acts to drive the population to extinction. The rich phenomenology of solution behaviour presented here arises from the nonlinear, nonlocal birth term. The existence of this kinetic nonlinearity accounts for the existence and propagation of soliton-like or front solutions, while the increasing effect of nonlocality and temporal delays acts to produce a fine periodic structure on the trailing part of the front. This nonlinear, nonlocal, and delayed kinetic term is also shown to be responsible for the existence of a Hopf bifurcation and subsequent period doublings to apparent "chaos" along the characteristics of this hyperbolic partial differential equation. In the time maturation plane, the combined effects of nonlinearity, nonlocality, and delays leads to solution behaviour exhibiting spatial chaos for certain parameter values. Although analytic results are not available for the system we have studied, consistency and validation of the numerical results was achieved by using different numerical methods. A general conclusion of this work, of interest for the understanding of any biological system modeled by a hyperbolic delayed partial differential equation, is that increasing the spatio-temporal delays will often lead to spatial complexity and irregular wave propagation.
