Social connections delay memory loss among elderly Americans
Using a nationally representative sample of U.S. individuals age 50 and over, researchers examined whether an individual's level of social connectedness predicted memory change over six years. Memory was measured by immediate and delayed recall of a 10-word list. The mean memory score declined from 11.0 in 1998 to 10.0 in 2004. Higher baseline social integration predicted slower memory decline, with memory among the least socially integrated declining at twice the rate of the most integrated.
"Being in the highest level of social integration ameliorated more than half of the age-related decline in memory"¦Our results suggest that increasing social integration may be an important component of efforts to protect older Americans from memory decline. Future research should focus on identifying the specific aspects of social integration most important for preserving memory," the study's authors stated.

Multilevel community-based intervention significantly increases interest in influenza vaccination in hard-to-reach populations
Researchers examined whether the work of community-based intervention increased interest in influenza vaccination among hard-to-reach individuals in urban settings. Intervention activities were conducted in eight racially and ethnically diverse and economically disadvantaged locations in East Harlem and the Bronx. "Hard-to-reach" populations of interest included substance abusers, possible undocumented immigrants, homeless persons, commercial sex workers and persons 65 years and older, including the homebound elderly. Through a five-phased intervention project, the authors of the study concluded that targeting underserved neighborhoods through this approach did significantly increase interest in influenza vaccination.
"In pandemic situations, gaining access to hard-to-reach populations for immunization could be particularly challenging," the study's authors said. "Unvaccinated populations may serve as undetected reservoirs of infection and key bridge populations, thereby limiting the effectiveness of population-wide vaccination efforts."

Increased risk of institutionalization high immediately after the death of a spouse
This study's objective was to analyze how the death of a spouse affects the probability of entering institutionalized care. The 140,902 study participants included Finnish adults aged 65 years or older living with a spouse at the beginning of the study period. Participants were followed for the next five years--from January 1998 to December 2002. Risk of institutionalization was particularly high immediately after the death of a spouse, demonstrating the importance of loss of social and instrumental support.
"These results provide indirect evidence of the effect of the loss of social and instrumental support on the risk of institutionalization," the study's authors stated. "Furthermore, we found that high levels of education and income did not buffer the effects of bereavement." [From: "Institutionalization of Older Adults After the Death of a Spouse," ].
