BACKGROUND Previous studies have shown that alendronate can increase bone mineral density (BMD) and prevent radiographically defined (morphometric) vertebral fractures. The Fracture Intervention Trial aimed to investigate the effect of alendronate on the risk of morphometric as well as clinically evident fractures in postmenopausal women with low bone mass.(More)
CONTEXT The optimal duration of treatment of women with postmenopausal osteoporosis is uncertain. OBJECTIVE To compare the effects of discontinuing alendronate treatment after 5 years vs continuing for 10 years. DESIGN AND SETTING Randomized, double-blind trial conducted at 10 US clinical centers that participated in the Fracture Intervention Trial(More)
Farmworkers are low-paid, uninsured employees in an extremely hazardous industry, and they provide an essential service for U.S. society. This review evaluates the delivery of health services to farmworkers. It describes the farmworker population in the United States, noting characteristics (e.g., migratory and immigration status) that limit their access to(More)
CONTEXT The number of Latinos in rural regions of the United States is increasing. Little is known about factors that undermine the mental health of this segment of the rural population. PURPOSE The goal of this study is to determine which stressors inherent in farmwork and the farmworker lifestyle contribute to poor mental health. METHODS An interview(More)
OBJECTIVE Food insecurity is defined as lack of access at all times, due to economic barriers, to enough food for an active and healthy lifestyle. The objective of this study was threefold: to characterize levels of food security, food insecurity, and hunger among migrant and seasonal Latino farmworkers; to assess predictors of food insecurity for this(More)
BACKGROUND Migrant and seasonal farmworkers are at risk for occupational illnesses from pesticide exposure, and the effectiveness of pesticide safety regulations has not been evaluated. It is important to learn from farmworker safety experiences to develop effective measures to improve agricultural workplace safety. METHODS Formative research included(More)
Children of farmworkers can be exposed to pesticides through multiple pathways, including agricultural take-home and drift as well as residential applications. Because farmworker families often live in poor-quality housing, the exposure from residential pesticide use may be substantial. We measured eight locally reported agricultural pesticides and 13(More)
Farmworkers experience a lack of control over the conditions of their work environment. In trying to reduce the effects of exposure to pesticides, most health care providers give instructions to farmworkers about how to protect themselves. Outreach programs that target farmworkers focus on health education and recommend washing hands, wearing appropriate(More)
STUDY OBJECTIVE The characteristics of some populations make epidemiological measurement extremely difficult. The objective of this study is to identify risk factors that explain variation among incidence densities and proportions of one occupational illness, green tobacco sickness, within one such special population, Latino migrant and seasonal farmworkers(More)
Household food insecurity is higher among minority households in the U.S., but few data exist on households of recent minority immigrants, in part because such households are difficult to sample. Four studies of a total of 317 Latino immigrant families were conducted in different regions and during different seasons in North Carolina. A Spanish translation(More)
