OBJECTIVE:

To estimate the prevalence of refractive errors in persons 40 years and older.

METHODS:

Counts of persons with phakic eyes with and without spherical equivalent refractive error in the worse eye of +3 diopters (D) or greater, -1 D or less, and -5 D or less were obtained from population-based eye surveys in strata of gender, race/ethnicity, and 5-year age intervals. Pooled age-, gender-, and race/ethnicity-specific rates for each refractive error were applied to the corresponding stratum-specific US, Western European, and Australian populations (years 2000 and projected 2020).

RESULTS:

Six studies provided data from 29 281 persons. In the US, Western European, and Australian year 2000 populations 40 years or older, the estimated crude prevalence for hyperopia of +3 D or greater was 9.9%, 11.6%, and 5.8%, respectively (11.8 million, 21.6 million, and 0.47 million persons). For myopia of -1 D or less, the estimated crude prevalence was 25.4%, 26.6%, and 16.4% (30.4 million, 49.6 million, and 1.3 million persons), respectively, of whom 4.5%, 4.6%, and 2.8% (5.3 million, 8.5 million, and 0.23 million persons), respectively, had myopia of -5 D or less. Projected prevalence rates in 2020 were similar.

CONCLUSIONS:

Refractive errors affect approximately one third of persons 40 years or older in the United States and Western Europe, and one fifth of Australians in this age group.

This document provides an overview of the most relevant developments in United States trade policy relating to Latin America and the Caribbean in 2002. U.S. policy continued to promote trade liberalization through advancing negotiations on multiple fronts- globally (WTO), regionally (FTAA) and bilaterally or sub regionally- with a view that the various negotiations are mutually reinforcing and seek to create a constructive competition for liberalization" among trade partners. The passage of Trade Promotion Authority (TPA) included in the Trade Act of August 2002 enhanced the U.S. Administration's ability to negotiate trade agreements. It provided an impetus to conclude bilateral negotiations with Chile as well as to advance a number of trade agreements currently under negotiation, including negotiations toward the Free Trade Area of the Americas (FTAA) and bilateral negotiations with Central America. The Trade Act also renewed the Generalized System of Preferences, extended the Caribbean Trade Partnership Act by liberalizing apparel provisions and augmented the Andean Trade Preference Act, increasing the list of duty free products. On the multilateral front, in partial fulfillment of the Doha mandate, the U.S. tabled in 2002 two comprehensive proposals for the reduction of trade barriers on agricultural and non-agricultural goods. Along with these trade liberalizing proposals, the U.S. Administration imposed temporary safeguard measures on key steel products to provide relief to the sectors of the steel industry that have been most affected by import surges. In addition, the U.S. Congress passed the 2002 Farm Security and Rural Investment Act that substantially increased U.S. domestic farm subsidies to shield domestic farm producers from competition from subsidized products from abroad."

Objective. To determine the association between nativity status and mammography utilization among women in the U.S. and assess whether demographic variables, socioeconomic factors healthcare access, breast cancer risk factors and acculturation variables were predictors in the relationship between nativity status and mammography in the past two years. ^ Methods. The NHIS collects demographic and health information using face-to-face interviews among a representative sample of the U.S. population and a cancer control module assessing screening behaviors is included every five years. Descriptive statistics were used to report demographic characteristics of women aged 40 and older who have received a mammogram in the last 2 years from 2000 and 2005. We used chi square analyses to determine statistically significant differences by mammography screening for each covariate. Logistic regression was used to determine whether demographic characteristics, socioeconomic characteristics, healthcare access, breast cancer risk factors and acculturation variables among foreign-born Hispanics affected the relationship between nativity status and mammography use in the past 2 years. ^ Results. In 2000, the crude model between nativity and mammography was significant but results were not significant after adjusting for health insurance, access and reported health status. Significant results were also reported for years in U.S. and mammography among foreign-born born women. In 2005, the crude model was also significant but results were not significant after adjusting for demographic factors. Furthermore, there was a significant finding between citizenship and mammography in the past 2 years. ^ Conclusions. Our study contributes to the literature as one of the first national-based studies assessing mammography in the past two years based on nativity status. Based on our findings, health insurance and access to care is an important predictor in mammography utilization among foreign-born women. For those with health care access, physician recommendation should further be assessed to determine whether women are made aware of mammography as a means to detect breast cancer at an early stage and further reduce the risk of mortality from the breast cancer.^
