Second Longitudinal Study of Aging: Baseline (Second Supplement on Aging, 1994-1996)

Investigators: National Center for Health Statistics

The Second Longitudinal Study of Aging (LSOA II) is a collaborative effort of the National Center for Health Statistics (NCHS) and the National Institute on Aging (NIA). Conducted ten years after the original LSOA, it is a prospective study with a nationally representative sample comprised of 9,447 civilian non-institutionalized persons 70 years of age and over in 1995. The specific aims of the study include: To provide a replication of the first SOA in order to determine whether there have been changes in the disability and impairment process among older persons between the 1980's and 1990's; To provide information on the sequence and consequences of health events, including utilization of health care and services for assisted community living, on the physiological consequences of disability such as pain and fatigue, on social consequences such as changes in social activities, living arrangements, social support, and use of community services, and on the deployment of assisted living strategies and accessibility of technological and environmental adaptations; To provide information on the causes and correlates of changes in health and functioning of older Americans, including social and demographic characteristics, preexisting and emerging physical illnesses, cognitive and emotional status, and social and environmental support; and To provide information on individual health risks and behaviors in the elderly including alcohol and cigarette use, use of hormone replacement therapy, receipt of important health screenings such as mammography and prostate exams, body mass and weight loss, physical activity, and diet and nutrition. The Second Supplement on Aging (SOA II), conducted as a supplement to the 1994 National Health Institute Survey (NHIS), served as the baseline for the LSOA II. Follow-up interviews were conducted in 1997–98 (Wave 2) and 1999–2000 (Wave 3). The baseline interview was administered face-to-face in the home by U.S. Census Bureau interviewers. The Wave 2 and Wave 3 follow-up interviews were administered using Computer Assisted Telephone Interviews (CATI) by the National Opinion Research Center at the University of Chicago. The interview data may be augmented by linkage to Medicare records, the National Death Index, and multiple cause-of-death records.

Youth Risk Behavior Surveys: 1992, 1993, 1995, 1997, 1999, and 2001

Investigators: Centers for Disease Control and Prevention (CDC)

The Youth Risk Behavior Surveillance System (YRBSS) is an epidemiologic surveillance system that was established by the Centers for Disease Control and Prevention (CDC) to monitor the prevalence of youth behaviors that most influence health. The results from the YRBS are used by CDC to (1) monitor how priority health-risk behaviors among high school students (grades 9-12) increase, decrease, or remain the same over time; (2) evaluate the impact of broad national, state, and local efforts to prevent priority health-risk behaviors; and (3) monitor progress in achieving three leading health indicators and 15 Healthy People 2010 national health objectives. Results are also used to help focus programs and policies for comprehensive school health education on the behaviors that contribute most to the leading causes of mortality and morbidity. CWP offers six years of YRBS data. The school-based YRBS focuses on priority health-risk behaviors established during youth that result in the most significant mortality, morbidity, disability, and social problems during both youth and adulthood. These include: behaviors that result in unintentional and intentional injuries; tobacco use; alcohol and other drug use; sexual behaviors that result in HIV infection, other sexually-transmitted diseases (STDs) and unintended pregnancies; dietary behaviors; and physical activity.

Study of the Effectiveness and the Economic Feasibility of Bone-Setting, 1994-1995

Investigators: Heikki Hemmilä

A Study of the Effectiveness and the Economic Feasibility of Bone-Setting was conducted between 1994 and 1995 at the Folk Medicine Center in Kaustinen, Finland. The study was conducted to determine whether bone-setting (a form of traditional Finnish folk healing) or light exercise therapy could ease back pain and improve function better than ordinary physiotherapy. The study was a randomized, single-blind, clinical trial that lasted 6 weeks. 114 patients with prolonged back pain were randomly assigned to receive therapy involving bone-setting, a light exercise regimen, or physiotherapy. Patients received up to ten 1-hour treatment sessions during the 6 week treatment period. Patients were evaluated at the start of the study, at 6 weeks, 3 months, 6 months, and 12 months. The main outcomes include several measures of spinal mobility, muscular performance, and back pain. Secondary outcome measures include Oswestry disability scores, number of sick-leaves, number of visits to health centers, other types of therapy received for back pain, health care costs, and quality of life.

Longitudinal Study of Aging 70 Years and Over 1984-1987; 1988; 1990

Investigators: National Center for Health Statistics

The Longitudinal Study of Aging (LSOA), conducted by the National Center for Health Statistics (NCHS) in collaboration with the National Institute on Aging (NIA), was designed to provide needed information on those factors implicated in the physical dysfunction and institutionalization of older persons in the United States. The study focuses on measuring changes in living arrangements and functional status experienced by the elderly in order to examine the path from health to functional disability to institutionalization and death. Its objectives include: (1) to study changes in functional status and living arrangements with the hope of recognizing potential points for intervention to prevent institutionalization and provide alternative forms of care to extremely elderly people, and (2) to study length of life and death rates by characteristics of the population that are not reported on death certificates, such as education, whether living alone or with others, frequency of contact with family or friends, and other characteristics. Four waves of data were collected. Baseline data were obtained in 1984 from 16,148 persons aged 55 and over as part of the Supplement on Aging (SOA) to the National Health Interview Survey (NHIS). Follow-up questionnaires were administered in 1986, 1988, and 1990 to 7,527 persons, 70 years of age and older at the time they participated in the SOA.

Alternative High School Youth Risk Behavior Study, 1998

Investigators: Centers for Disease Control and Prevention (CDC)

The Youth Risk Behavior Surveillance System (YRBSS) is an epidemiologic surveillance system that was established by the Centers for Disease Control and Prevention (CDC) to monitor the prevalence of youth behaviors that most influence health. The 1998 national alternative high school Youth Risk Behavior Survey (YRBS) is one component of the YRBSS. The YRBS focuses on health-risk behaviors established during youth that result in the most significant mortality, morbidity, disability, and social problems during both youth and adulthood. These include: behaviors that result in unintentional and intentional injuries; tobacco use; alcohol and other drug use; sexual behaviors that result in HIV infection, other sexually-transmitted diseases (STDs), and unintended pregnancies; dietary behaviors; and physical activity. Results from the Alternative High School YRBS are used by CDC to: (1) identify the prevalence and age of initiation of priority health-risk behaviors among students attending alternative high schools; and 2) identify the need for school health programs and policies for students attending alternative high schools. Four previous versions of the YRBS have been archived at Sociometrics. The 1992 survey (DAAPPP data set K9), the 1993 (data set M1), 1995 (data set N4), the 1997 (data set P5), and the 1999 (data set P7). Each of these data sets is cross-sectional.

National School-based Youth Risk Behavior Survey, 2003

Investigators: Centers for Disease Control and Prevention (CDC)

The Youth Risk Behavior Surveillance System (YRBSS) is an epidemiologic surveillance system that was established by the Centers for Disease Control and Prevention (CDC) to monitor the prevalence of youth behaviors that most influence health.
