Prevalence of depressive symptoms in new Mexico Hispanic and non-Hispanic white elderly.

OBJECTIVE: To evaluate the prevalence rates, risk factors, and pattern of depressive symptoms in elderly Hispanic and non-Hispanic Whites (NHWs). METHODS: This survey was a community-based, cross-sectional survey of randomly selected Medicare recipients living in Bernalillo County (Albuquerque, New Mexico). The survey's objective was to examine the health and health-related issues of Hispanic and NHW elderly persons (> or =65 years of age). As part of the survey, participants were administered the Geriatric Depression Scale-short form (GDS). RESULTS: Complete data were available on 798 subjects with a mean age of 73.7 years, age range 65-96. The prevalence of a GDS score > or =6 was: Hispanic males, 9.5%; Hispanic females, 19.2%; NHW males, 5.4%; and NHW females, 8.7%. Hispanics (P=.001) and women (P=.003) had higher prevalence rates. Sociodemographic variables, health, social support, and the activities of daily living (ADLs) were significantly related to symptoms. English skills (P<.0001) and birthplace (P=.011) were associated with symptoms in Hispanics. Significant differences were found in the response patterns between Hispanics and NHWs. Logistic regression analyses showed that ethnic differences were largely explained by differences in the level of education and income among Hispanics and NHWs. CONCLUSION: A difference was seen in the prevalence rates of depressive symptoms between Hispanic and NHW elderly persons and between men and women. In addition to the traditional risk factors for depressive symptoms, we found that ethnic differences in prevalence rates can be largely explained by education and income differences in the two groups.

Emotional responses to APO E genotype disclosure for Alzheimer disease.

The purpose of our study is to assess the emotional responses to disclosing APO E genotype to asymptomatic older adults at increased risk for Alzheimer disease (AD). This is a longitudinal cohort study of volunteer subjects who were aged 50 years or over, asymptomatic for (AD), had a family history of AD, passed a psychological assessment, and participated in pre- and post-test genetic counseling and three follow-up visits over 10 months. We analyzed responses by three emotional constructs: depressed, worried, and relieved. Three hundred and twenty-eight subjects were screened, 76 received their APO E genotype. When emotional responses occurred it was immediate, between baseline and the 1 month follow-up. Emotional reactions did not change significantly past 1 month. Our results suggest that for emotionally stable persons, disclosing results of their APO E genotype, high risk subjects did not report more depression or worry and low risk subjects felt relieved by knowing the results. Future studies should evaluate the risks of disclosure to family members involved in the diagnostic work-up of a relative and include subjects from a broader range of emotional stability and socioeconomic background.
