Summary

The Sacramento Area Latino Study on Aging (SALSA Study) was a longitudinal cohort study of 1,789 community-dwelling Mexican Americans residing in California's Sacramento Valley who were aged 60-101 years at baseline in 1998-1999. Participants were followed every 12-15 months via home visits that included clinical and cognitive assessments. A semiannual phone call was made to obtain updates on medications, health events, and some sociodemographic risk factors. This study, Semi-Annual Phone Call Data, contains data from the six-month follow-up calls of the SALSA project.

The SALSA project tracked the incidence of physical and cognitive impairment as well as dementia and cardiovascular diseases in elderly Latinos in the Sacramento, California region. The SALSA project aimed to assess cognitive, physical, and social functions, which include the ability to follow instructions, to perform certain movements, and to interact with others. The project explored the effects that cultural, nutritional, social, and cardiovascular risk factors have on overall health and dementia, and examined the association between diabetes and functional status.

Demographic information collected in these data includes language and age given at follow-up visits.

Data Collection Notes

  1. These data are being released in BETA version to facilitate early access to the study for research purposes. This collection has not been fully processed by NACDA or ICPSR at this time; the original materials provided by the principal investigator were minimally processed and converted to other file types for ease of use. As the study is further processed and given enhanced features by ICPSR, users will be able to access the updated versions of the study. Please report any data errors or problems to user support and we will work with you to resolve any data related issues.

  2. Data from the SALSA project were originally made available as one study (ICPSR 22760) which has subsequently been divided into several individual studies now comprising the Sacramento Area Latino Study on Aging (SALSA) Series.

Study Purpose

The purpose of the Semi-Annual Phone Call Data for the SALSA study was to obtain updates on medications, health events, and some sociodemographic risk factors throughout participation in the SALSA study.

Study Design

Baseline interviews asked questions about lifestyle factors, depressive symptoms, acculturation and medical diagnoses. They assessed participants' demographics, including their socioeconomic mobility from childhood to adulthood, as well as nativity. Additional medical measures were taken, including blood pressure, blood analyses, and physical performance tests. At each home visit participants received two cognitive tests, The Modified Mini-Mental State Examination (3MSE) and the Spanish English Verbal Learning Test (SEVLT). Scores from these tests determined whether further neuropsychological testing was conducted. Random sampling of every fifth participant was used to refer an additional 20% of participants for neuropsychological testing. Formal neuropsychological testing utilized a test battery including the Spanish English Neuropsychological Assessment Scales and the Informant Questionnaire on Cognitive Decline in the Elderly. Participants determined to be demented from these scores were referred for MRI and appropriate lab tests. Participants were followed every 12-15 months via home visits that included the clinical and cognitive assessments. Prescription medication was also assessed via a medicine cabinet inventory during each annual home visit, and this information was coded into groups. A semi-annual phone call was made in tandem to obtain updated clinical information. During these phone calls, interviewers asked participants about changes to medication use- including new medications and removal of medications- information about health events such as hospitalizations, and updates to sociodemographic risk factors.

Sample

Study participants were residents of the Sacramento Metropolitan Statistical Area and surrounding suburban and rural counties in California. Begun in 1996, the original SALSA baseline includes 1,789 Latinos from the Sacramento area age 60 and older, participating for up to five years. The Semi-Annual Phone Call Data include a decreasing number of the original participants due to attrition, including mortality and loss to follow up. Dataset one includes 1,527 participants, dataset two includes 1,407, dataset three has 1,270, and dataset four has 1,094.
