A longitudinal cohort study of the impact of first- and both-eye cataract surgery on falls and other injuries in Vietnam.

Aim: Little information exists on the impact of cataract surgery on falls and other injuries in Vietnam. The aim of this study was to determine the impact of first and both eye cataract surgery on the number of falls and other injuries among bilateral cataract patients in Ho Chi Minh City, Vietnam.

Materials And Methods: A longitudinal cohort study was conducted involving 413 bilateral cataract patients aged 50+ years.

Prevalence and visual risk factors for falls in bilateral cataract patients in Ho Chi Minh City, Vietnam.

Purpose: To determine the prevalence of falls in the 12 months prior to cataract surgery and examine the associations between visual and other risk factors and falls among older bilateral cataract patients in Vietnam.

Methods: Data collected from 413 patients in the week before scheduled cataract surgery included a questionnaire and three objective visual tests.

Results: The outcome of interest was self-reported falls in the previous 12 months.

The impact of cataract surgery on vision-related quality of life for bilateral cataract patients in Ho Chi Minh City, Vietnam: a prospective study.

Background: To determine the impact of cataract surgery on vision-related quality of life (VRQOL) and examine the association between objective visual measures and change in VRQOL after surgery among bilateral cataract patients in Ho Chi Minh City, Vietnam.

Methods: A cohort of older patients with bilateral cataract was assessed one week before and one to three months after first eye or both eye cataract surgery. Visual measures including visual acuity, contrast sensitivity and stereopsis were obtained.

Assessing the test-retest repeatability of the Vietnamese version of the National Eye Institute 25-item Visual Function Questionnaire among bilateral cataract patients for a Vietnamese population.

Aim: To determine the test-retest repeatability of the National Eye Institute 25-item Visual Function Questionnaire (NEI VFQ-25) for use with older Vietnamese adults with bilateral cataract.

Methods: The questionnaire was translated into Vietnamese and back-translated into English by two independent translators. Patients with bilateral cataract aged 50 and older completed the questionnaire on two separate occasions, one to two weeks after first administration of the questionnaire.

The impact of cataract surgery on depressive symptoms for bilateral cataract patients in Ho Chi Minh City, Vietnam.

Background: Depression is common among older populations with cataract. However, the impact of cataract surgery on depression in both developed and developing countries remains unclear. The aim of this study is to determine the impact of cataract surgery on depressive symptoms and to examine the association between objective visual measures and change in depressive symptoms after surgery among a Vietnamese population in Ho Chi Minh City.

Validation of the Educational Stress Scale for Adolescents (ESSA) in Vietnam.

Introduction: To date, there has been little systematic, quantitative research on the links between academic pressure and mental health among adolescents in Asia, and none in Vietnam. In part, this is because of a lack of appropriate tools to measure this complex phenomenon. This study was to validate the Educational Stress Scale for Adolescents (ESSA), developed and tested in China, with the aim of fostering further research in Asia.

Test-retest repeatability and relative validity of the Global Physical Activity Questionnaire in a developing country context.

Background: The increasing prevalence of chronic lifestyle diseases in developing countries warrants reliable and valid surveillance of physical activity levels in the population. This study assesses the test-retest repeatability and criterion validity of the WHO-recommended Global Physical Activity Questionnaire (GPAQ) in Vietnamese adults during the dry and wet seasons.

Methods: In 2007 a representative sample of 169 adults (25-64 years) was recruited to determine the GPAQ reliability and validity.
