Defined Population Studies
Defined population studies are designed to measure the impact of an
intervention in a defined target population (i.e. women, racial and ethnic
minorities). These studies can provide further validation of the methods
utilized and information about whether or not an intervention works in various
population groups.
- Lay Health Workers and the Promotion of
Colorectal Cancer Screening Among Chinese Americans
National Cancer Institute (NCI)
This study investigates characteristics of lay health workers in Chinese
American communities and evaluates the health workers' effectiveness as health
educators for promoting colorectal cancer screening in adults aged 50 to 75. The
findings will expand our understanding about effective and culturally
appropriate cancer prevention techniques among ethnic minority communities.

Geographic and Contextual Influences on Energy
Balance-Related Health Behaviors
National Cancer Institute (NCI)
These four studies focus on energy balance-related health behaviors. Topics
include obesity, physical activity, eating behavior, and the impact of
environmental factors affecting obesity on breast, colorectal, and prostate

can aid us in the development of prevention measures for obesity and its
comorbidities.

Folic Acid, B-Vitamins, and Age-Related Macular
Degeneration: Blood and Diet-based Studies
National Eye Institute (NEI)
Based on information from previous trials, this trial seeks to investigate the
causal relevance of the amino acid homocysteine to age-related macular
degeneration and to evaluate the possible preventive benefits of folic acid and
B vitamins. This study will use blood samples from men and women who were
diagnosed with macular degeneration to examine the effect of folic acid and B
vitamins on homocysteine levels.

Middle School Youth
National Institute on Alcohol Abuse and Alcoholism (NIAAA)
Middle school years are peak years for initiation of alcohol and marijuana use.

services. The purpose of this study is to evaluate the effectiveness of Project
CHOICE, an intervention program in Los Angeles, California aimed at minimizing
the use of drugs among youth.

Effectiveness of Proactive Tobacco Treatment in
Diverse Low-Income Smokers
National Cancer Institute (NCI)
There is a high prevalence of smoking and a high burden of tobacco-related
disease among low-income populations. This study evaluates the effects of
proactive outreach coupled with free telephone counseling on the population
impact of tobacco dependence treatment. If effective, this intervention could
reduce tobacco-related morbidity, mortality, and health care costs for low-income populations.
-
Barriers to Cervical Cancer Prevention in
Hispanic Women
National Cancer Institute (NCI)
This study examines how individual, interpersonal, and community factors affect
the likelihood Hispanic women will take the steps necessary to prevent, detect,
and treat cervical cancer. Through surveys and observation, this study will
provide an improved understanding of how to best communicate information about
cervical cancer and facilitate screening among Hispanic women to maximize
prevention.

Prevention of Substance Abuse Risks in American
Indian Teen Families
National Institute on Drug Abuse (NIDA)
The Family Spirit intervention is designed to promote mothers' effective
parenting practices. This research addresses critical behavioral health
disparities and drug abuse among American Indian teen mothers and their children
in communities located on reservation lands. This study sets out to expand early
intervention with teen mothers in this and similar populations and to prevent
behavior problems in young children that lead to adolescent and adult drug use.
