Weight Loss on Vegan Diet
American Journal of Medicine (September 2005)
A group of 59 overweight and postmenopausal women ages 44 to 73 was divided into two groups, where half ate a low-fat vegan diet of vegetables, fruits, grains, and legumes, and the other half followed a more moderate low-fat diet. At the pre-study level, participants were instructed to maintain exercise and not to limit their portions. Both groups attended a one-hour meeting once a week, and they prepared their own meals or ate at restaurants. After 14 weeks, the vegan group lost a mean of 12.7 pounds of body weight compared with the control group, which lost a mean of 8.3 pounds of body weight. The vegan group had significantly greater reductions of body mass index and waist circumference and enjoyed unlimited servings of fruits, vegetables, whole grains, and other healthy foods that enabled them to lose weight without feeling hungry.

Soy Protein Cuts Bone Loss
Archives of Internal Medicine (September 12, 2005)
Eating soy-based foods lessens the progress of osteoporosis in women after menopause, a time when hormonal changes can rapidly thin bones and increase the risk of fractures. Replacing estrogen through hormone replacement therapy has been found to carry health risks, including stroke. Soy protein from soy milk, tofu, soy sprouts, and fresh soybeans has been viewed as a possible alternative. In this study, a sampling of 24,000 women participating in the three-year Shanghai Women’s Health Study, found post-menopausal women who ate the most soy protein had a 37 percent lower risk of bone fracture compared with women who consumed the least soy. The women were divided into five categories of soy consumption, with those in the highest-consuming group eating at least 13 grams per day, while the low-consuming group ate five grams per day.

Regular Exercise Fights Pain
Arthritis Research & Therapy (September 2005)
Older persons who exercise regularly experience fewer aches and pains than other people their age who are less active. For 14 years, researchers followed a group of running club members and a similar group of non-runners in their mid-60s. Overall pain increased in both groups during the study, but regular exercise was associated with a significant reduction in pain over the long term. Runners, however, had a slightly higher percentage of broken bones reported during the study. Researchers found joint and muscle pain to be 25 percent lower among the regular exercisers, compared with their more sedentary counterparts. Researchers say this reduction in pain persisted over the average ages of 62 to 76 after adjusting for age, sex, and body mass index. |

Fitness and Mobility Exercise Program Helps Stroke Patients Journal of the American Geriatrics Society (October 2005)
To examine the effects of a community-based group exercise program for older individuals with chronic stroke, 63 persons with chronic stroke who were living in the community were randomized into an intervention group or control group. The intervention group underwent a fitness and mobility exercise (FAME) program designed to improve cardiorespiratory fitness, mobility, leg muscle strength, balance, and hip bone mineral density. One-hour sessions took place three times a week for 19 weeks. The control group underwent a seated upper extremity program. The intervention group had significantly more gains on all outcome measures than controls. The FAME program is beneficial for improving the complications resulting from physical inactivity in older adults living with stroke. It may serve as a model of a community-based fitness program for preventing secondary diseases in adults with chronic conditions.

Employees Who Are Caregivers
Center on an Aging Society (September 2005)
The new report Caregiving and Paid Work: Are there tradeoffs? examines both working and non-working caregivers ages 25 to 64. It notes that about one-third of all caregivers, regardless of age, are in the workforce. Among those primary caregivers of working age, 58 percent are employed, with more than 80 percent employed full-time. The report discusses the issues associated with working caregivers, including effects on productivity, work adjustments, use of formal services, and other factors. The report can be found at www.aging-society.org.

A Look at Working-Age Caregivers' Roles
The Commonwealth Fund (September 2005)
A new study reports that more than half of the nation’s 16 million caregivers, or nine million adults, have health problems of their own, and many cope with severe financial stress. Researchers say caregivers ages 19 to 64 are more likely than non-caregivers to not be working, to miss days of work if they are employed, and to lack health insurance coverage. As a result, many are financially vulnerable and struggle to obtain needed medical care. The authors urge policymakers to take steps to ease caregivers’ burdens. For more information, see A Look at Working-Age Caregivers’ Roles, Health Concerns, and Need for Support, at http://www.cmwf.org/publications/publications_show.htm?doc_id=293045. |

1.4 Million American Kids Are Caregivers
National Alliance for Caregiving and the United Hospital Fund
(September 2005)
As many as 1.4 million American children between the ages of eight and 18 provide care for an older adult, including approximately 400,000 kids between the ages of eight and 11. These and other data are contained in the landmark study Child Caregivers in the United States: Findings from a National Study. Researchers also found that young caregivers – half of whom are boys – are more likely to come from households with lower incomes; are less likely to be from a two-parent home; and are more likely than their non-caregiving counterparts to experience depression and anxiety. The survey Child Caregivers: A First Look at an Unstudied Population can be seen at http://www.caregiving.org/pubs/.

Complex Work May Cut Risk
Journal of Gerontology: Psychological Sciences (September 2005)
In a study of more than 10,000 older Swedish adults who were part of a twin registry, researchers found that people with a history of “complex” work had a lower risk of Alzheimer’s disease. The same held true even among twin pairs in which one was affected by Alzheimer’s but the other was not – a situation that factors in the influence of genes and upbringing. The study found that the complexity of a worker’s interactions with other people – with teaching as an example of higher complexity – showed the strongest link to a lower risk. Men and women with the most challenging jobs were 22 percent less likely to develop the disease compared with those who did the least complex work. The findings fit in with other research that has linked higher education, as well as mentally stimulating leisure activities like reading and doing crossword puzzles, to a lowered risk of Alzheimer’s disease.

Green Tea May Also Offer Protection
Journal of Neuroscience (September 2005)
An ingredient in green tea may protect the brain from Alzheimer’s disease. Scientists injected mice with an antioxidant from green tea called EGCG and found that it significantly decreased the production of beta-amyloid, a protein that forms brain-clogging plaques in persons with Alzheimer’s. Drinking ordinary green tea may not lead to the same plaque reduction seen in the study because other ingredients in tea appear to block EGCG’s benefits. Supplement pills containing EGCG might help, however. Humans would probably need 1,500 milligrams per day of EGCG to get the amount that helped mice. Researchers have tested the safety of this dose in people and found no major side effects. The next step is to test an oral form of EGCG in mice to examine if it protects their memory. If those studies show clear benefits, human trials would be warranted.

A Call for Action
Alzheimer’s Spoken Here (September 6, 2005)
A growing number of people with Alzheimer’s disease and related dementias are becoming more outspoken about their need for recognition and participation in decisions that affect them. A grassroots effort is underway that urges the Alzheimer’s Association to adopt a 10-point plan aimed at encouraging the Chicago-based organization to be more inclusive of people with dementia on a local and national level. This “Call for Action” is being signed by people with dementia and their family members, friends, and professionals. The document and signatures will be presented to the Association’s leadership team this month. You can view or download the “Call for Action” and signature forms at www.alzsh.net. |

Improving Retention of Direct Care Staff
Institute for the Future of Aging Services (August 25, 2005)
This 394-page guide gives long-term care providers tools for improving retention of direct-care workers. Measuring Long-Term Care Work: A Guide to Selected Instruments to Examine Direct Care Worker Experiences and Outcomes helps providers in residential, home care, and other long-term care settings create employee surveys tailored toward their values and goals. The guide also provides tools for measuring other factors such as turnover. Asking workers what changes they’d like to see is the most effective and efficient way for an organization to learn how to improve employee satisfaction and retention. Employee surveys can quickly tell managers whether it is best to focus on supervision, skill development, or advancement opportunities. The report includes sample surveys, letters, and guidance on how to analyze and act on the opinions expressed. To read the report, go to www.futureofaging.org/page.cfm?name=News&nid=12.

Activities Improve Sleep Patterns in Nursing Home Residents
Journal of the American Geriatrics Society (September 2005)
This study of 141 nursing home residents with dementia tested the efficacy of an individualized social activity intervention on decreasing daytime sleep, improving nighttime sleep, and lowering the day/night sleepratio. The intervention consisted of one to two hours of individualized social activities for 21 consecutive days. Twenty-four-hour sleep/wake patterns were measured using an Actigraph. The intervention group had significantly less daytime sleep and a lower day/night sleep ratio than the control group. The weekly cost of the intervention was approximately $70 per participant. |

Advances Will Extend Lives but Not Curb Costs
Health Affairs (September 26, 2005)
Technological innovations will improve people’s health and extend their lives, yet they will do nothing about curbing the soaring cost of medical care for older adults. In fact, the advances probably will inflate the cost of Medicare, according to analysts at the RAND Corporation. Its study included a look at 10 medical technologies such as expanding the use of implantable defibrillators for life-threatening heart conditions. If half of the patients with new cases of heart failure or heart attacks got the devices, health care spending on older adults would increase by $14 billion, or four percent, over the next 10 years. |

Help for Dying Patients
Journal of Clinical Oncology (September 2005)
Helping dying people to relive and record important memories and thoughts may ease the distress many feel at the end of life. Researchers found that “dignity” therapy offers terminally ill patients the chance to talk about their lives and accomplishments and to say anything they feel their friends and families should know. The process is recorded, transcribed, and given to a family member or friend. Of the 100 persons who underwent the therapy as part of hospice or home-based care, 91 percent said they were satisfied with it. In addition, 81 percent said it would help or had already helped their families, while more than two-thirds said it had enhanced their sense of meaning and purpose in life.

Latest Profile of Older Americans
U.S. Administration on Aging (September 2005)
The population of those ages 65 and older in the U.S. reached 35.9 million in 2003, a 9.5 percent increase since 1993. Half of women ages 75 and older in the U.S. live alone, and 416,000 grandparents ages 65 and older have primary responsibility for grandchildren who live with them. These and other facts are included in A Profile of Older Americans: 2004, a concise document from the U.S. Administration on Aging. See the report at http://www.aoa.gov/prof/statistics/profile/2004/profiles2004.asp.
